[Methods and systems for selection of compression cut-fracture for fueling combustible waste]

The present invention relates to a compression cutting crushing method and a sorting system for converting combustible waste into fuel, and more preferably, household waste discharged from homes and large-scale unsanitary landfills generated from residential land development projects or trunk line SOC projects, or illegal in the past. The combustible waste (waste vinyl, waste synthetic resin, etc.) buried in the unsanitary landfill is collected and naturally dried in a drying site, and then attached to and mixed with combustible waste in the primary pretreatment process, reduction screening process. After sorting and transferring foreign substances such as scrap iron to the combustible fuel sorting device, foreign substances such as soil, earth and ash, which are an impediment to the heating amount of combustibles, as well as foreign substances such as soil, soil and ash, as well as metals are precisely sorted and separated to reduce the amount of compression and cutting. Using a crushing device, malicious coarse waste is compressed into a small shape, then cut and crushed, and the moisture contained in the combustible waste is discharged during compression and dried in a dryer, thus enhancing the efficiency of selecting combustible waste and being used as fuel. Compressed to convert combustible waste into fuel to select high-quality combustible waste that meets the specifications of Fluff's SRF (non-molded solid fuel) by pulverizing it to the size suitable for the following, and finally wrap it in a wrapping device so that it can be used as fuel. This is a technology related to the cutting and shredding screening method and screening system.

Recently, technologies and policies for securing energy using waste resources are being actively promoted globally to reduce greenhouse gases due to resource depletion and climate change, and advanced countries such as Europe and Japan are seeking to recover energy contained in waste. In other words, the expansion of facilities for fuel conversion (MT (Mechanical Biological Treatment) or MBT (Mechanical Biological Treatment)), a production technology of SRF (Solid Refuse Fuels), is on the rise.

In Korea, the quality standards of solid fuels and regulations on manufacturing facilities and storage facilities have been amended and implemented under the “Act on the Promotion of Resource Conservation and Recycling”.

Among the fuels that can be recycled as such, combustible wastes that can be recycled and construction wastes such as soil and aggregates are not sorted out of the waste wastes buried in unsanitary landfills or recycling landfills. Therefore, the amount of waste waste reclaimed and its treatment The cost is increased and the water content of the waste waste is high, so the proportion of waste waste is high even after sorting, and due to this, the disposal cost of the waste waste is excessive, and leachate, odor and fugitive dust are generated from the landfilled waste. While causing pollution, recyclable resources are wasted.

In addition, when combustible waste mixed with waste is incinerated, combustible gas is discharged.This combustible gas can be reused as fuel, but it is impossible to recover and reuse useful combustible gas with a conventional incineration method, thus wasting resources. Results.

Therefore, waste garbage is separated into recyclable resources, combustible incineration garbage and landfill garbage, and only non-recyclable garbage is incinerated or buried to be disposed of, thereby significantly reducing the amount of garbage to be treated, while reprocessing the selected garbage in a dry sorting separator. There is a need for efficient treatment by minimizing the amount of incineration or landfill by putting in and drying, removing foreign substances to reduce the amount.

As movements to solve these problems become active, technologies such as extracting industrial oil or combustible gas using combustible waste that has been incinerated or reclaimed or producing alternative fuels such as solid fuel (SRF) are being developed.

However, combustible wastes do not only contain pure combustible wastes, and contain various foreign substances. In particular, the wastes that have been buried contain ash-like foreign substances such as a large amount of soil, stone, and fine powder, and a large amount of moisture.

Therefore, the conventional landfill waste treatment technology requires a pretreatment process of removing various foreign substances and moisture before producing gas or fuel using combustible waste as well as recycling technology such as soil.

Conventional techniques for removing foreign substances mixed with combustible waste mostly use water treatment, and various foreign substances are removed by putting mixed waste (a mixture of combustible waste and foreign substances) into a water tank and washing the combustible waste with washing water, This is a method of drying the combustible waste using a dryer.

Therefore, the conventional technology for removing various foreign substances mixed with combustible waste requires a lot of energy and power because it requires large facilities such as a water tank and a dryer, and requires not only a large site, but also a lot of manpower, and also work time. There is a problem with this lengthening.

In addition, since the water treatment method removes foreign substances by removing the adhesion between the combustible waste and foreign substances, the efficiency of removing foreign substances is lowered, while the washing water used to remove foreign substances can be reused, but since a large amount of foreign substances is mixed in this washing water, foreign substances must be removed. And, since the method of removing foreign substances from the washing water usually goes through processes such as precipitation and foreign substances aggregation, there is a problem that a large facility for recycling the washing water is required.

Thus, Korean Patent Laid-Open Publication No. 10-2015-0145726 "mass fuel sorting system for buried combustible waste applied with natural drying process" was disclosed, but the above configuration was dried in a drying area to remove only the moisture content contained in the combustible waste. When the waste is transferred to the combustible fuel sorting system, since quantitative supply is not made, the combustible fuel sorting system is overloaded, and thus it was not possible to prevent loss of repair costs and operating time due to failure.

In addition, since the combustible waste collected at the landfill is transferred directly to the combustible fuel sorting system without first sorting and reducing the sediment in the pretreatment process, the reduction and sorting of combustible waste is not efficient, making it unsuitable for use as a high-quality fuel.

In addition, since the selected combustible waste is dried only with heat of 120~200℃ generated from the heater even when drying, it is impossible to completely remove fine powder or soil that remains in the dry combustible waste and adheres or mixed. Therefore, there is an unsuitable problem in using the reduced waste as a high-quality fuel that meets the standards of Fluff's SRF (non-molded solid fuel).

And, as disclosed in Republic of Korea Utility Model No. 20-0447204, when the reduced combustible waste is directly put into the hopper of the drying device and dried, the hopper is automatically inserted because air is filled between the combustible waste that is put into the hopper. Because it is not put in manually or as an input device for putting inflammable waste into the hopper, manual input can result in wasted labor costs or safety accidents, and installing the input device in the hopper leads to high cost. As it had to be expenditured, a factor of cost increase occurred.

In addition, when the reduced combustible trash is put into the hopper of the drying device, the combustible trash is not uniform in length and is formed long in the longitudinal direction.Therefore, air pressure is generated between combustible trash and when it is put into the hopper, the same problem as the prior art. This is what happens.

In addition, as disclosed in Korean Patent Registration No. 10-1561611, when the reduced combustible waste is sorted and packaged using a packaging device, a hydraulic motor is applied, so that the conveyor system is simple and the appearance design is good. However, when all processes are applied with a hydraulic motor, there is a problem that the production cost of the wrapping package increases due to the increase in manufacturing cost and power cost.

Republic of Korea Patent Publication No. 10-2015-0145726 Republic of Korea Patent Publication No. 10-2014-0098352 Korean Patent Registration No. 10-1373117 Korean Patent Registration No. 10-1142140 Republic of Korea Utility Model Registration No. 20-0447204 Korean Patent Registration No. 10-1561611

As described above, the present invention is a method for completely removing various foreign substances (wood and metal, etc.), such as soil mixed with conventional combustible waste, before processing through the drying and pulverizing process, which is the present process. In order to solve the problems of requiring large facilities such as water tanks and dryers, and the need for a lot of energy and power to dry unnecessary foreign substances, the combustible waste created to improve the problems of requiring a lot of manpower and lengthening the working time. Its purpose is to provide a sorting method and a sorting system for fueling.

In other words, the combustible waste is pre-dried in the pretreatment reduction screening process, cut to a certain size or less in a large shredder and a medium shredder, and then reduced by sorting and reducing flammable and soil foreign matters in a return method, and transferred to a combustible fuel sorting device, a post-treatment facility. The purpose of this is to process combustible waste obtained with high purity into fuel by making the reduction operation more efficient due to compression and cutting and crushing.

In addition, since combustible waste can be quantitatively input when inputting the combustible waste into the combustible fuel sorting device, there is no irregular overload on the combustible fuel sorting device and the sorting operation is continued, thereby preventing loss of repair costs and operating time. can do.

In addition, the present invention transfers foreign matter remaining in the combustible waste selected in the weight reduction screening process to a multi-stage mesh conveyor belt, and at the same time performs drying and sorting through a drying device for drying with hot air, and drying and sorting. Afterwards, the dust, such as soil attached to the combustible waste, is finally removed by the vibrating screen of the vibrating and striking device and the ash, which is the foreign matter adhering to the combustible waste, through the hitting action of the rotary striker installed on the top and bottom of the vibrating screen. Because it is completely separated and sorted, high-quality combustible waste can be converted into fuel to meet the FSRF standard of Fluff Type.

In addition, the present invention compresses the reduced-selected combustible waste with a compressor, and then compresses the compressed combustible waste into a small shape by compressing the malicious coarse waste in one cutting process using a horizontal cutter and a vertical cutter. Since it is a method to achieve this, the size and volume of combustible waste can be drastically reduced, as well as by removing moisture by compression in advance, reducing the size of combustible waste and removing moisture when putting it into the hopper of the drying furnace. It is to prevent and increase the drying effect.

In addition, the present invention prevents the overload of the crushing and sorting process, which is a downstream facility, because the coarse garbage having a large size and volume is cut and crushed at the same time by compression. The purpose is to prevent overloading of downstream facilities and drastically reduce the operating cost of the drying furnace as it can be cut and crushed to smoothly input combustible waste.

Each of the major processes according to the present invention will be described in more detail in correspondence with the drawings as follows.

1. Pre-treatment selection and reduction process (S1)

Household waste from households and large-scale unsanitary landfills generated from residential land development projects or trunk line SOC projects, or combustible waste (waste vinyl, waste synthetic resin, etc.) that were illegally buried in the landfill in the past are collected and dried naturally in a drying site.

At this time, natural drying is natural drying using sunlight, but it is also possible to dry combustible waste (including household waste) with a dryer that uses electric energy charged in a rechargeable battery by condensing solar heat through a solar dust collecting module installed according to the site conditions. have.

In addition, the present invention does not directly input the dried combustible waste into the combustible fuel sorting device 900 for selective processing, but in advance through the pretreatment sorting reduction device 200 in order to manufacture high quality combustible fuel (SRF). After completely sorting and reducing the amount of soil and foreign matter mixed with the waste, it is transferred to the combustible fuel sorting device 900, which is a post-treatment facility, so that it can be selectively processed.

That is, as shown in FIG. 3, the dried combustible waste is fed into a quantitative supply device (A) for quantitatively supplying the dried combustible waste, and the soil and combustible waste of 100 mm to 150 mm or less are sorted through the primary trommel separator 10. Since the primary trommel separator 10 is a known technology, a detailed description of the configuration will be omitted.

In addition, foreign substances such as combustible garbage and earth and stone of 100mm~150mm or more through the first trommel sorter 10 are discharged to a conveyor belt and transferred to the first combustible waste sorter 130 to sort foreign substances such as combustible garbage and non-combustible earth and stone. And discharge.

In addition, the sorted soil and combustible waste of less than 100mm ~ 150mm are transported on a conveyor belt, and the inner sorting drum 21 and the outer sorting drum 22 are combined to form an integral part 2 for precise sorting of secondary combustible waste. The soil of 25mm or less is sorted and discharged through the trommel sorter 20, and the sorted combustible waste of 25mm or more is transported to the secondary reduction sorter 131 on a conveyor belt to sort and discharge the soil.

In addition, the sorted soil of 25 mm or less is transported to the soil precision sorting machine 11 on a conveyor belt to sort the soil and combustible waste to discharge the soil. Then, the sorted combustible waste is transferred to the secondary reduction sorting machine 131 after being combined with the combustible waste discharged from the double trommel sorter 20 for precise sorting of combustible waste.

In addition, as shown in FIG. 6, the double trommel sorter 20 has a cylindrical inner sorting drum 21 and an outer sorting drum 22 in which a plurality of through holes 21a and 22a are perforated on the outer circumferential surface. It is formed by bonding. The inner sorting drum 21 sorts soil of less than 65 mm, and the outer sorting drum 22 sorts soil less than 25 mm.

In addition, as shown in Figure 3, the inlet of the primary and secondary flammability reduction separator (130, 131) is equipped with a hot air fan (130a) (131a) by the hot air generated from the hot air, foreign substances such as soil and combustible garbage. Are selected by specific gravity. At this time, the primary and secondary flammability reduction separators 130 and 131 are also cylindrical sorting drums (trommels), and a plurality of through holes are drilled on the outer circumferential surface to sort the soil and discharge it to the outside.

The first combustible waste sorter 130 sorts and discharges combustible waste, and the sediment and foreign matters sorted and discharged to the lower part are transferred to the second weight loss sorting machine 131 by riding a conveyor belt. In addition, the second reduction sorter 131 sorts and discharges combustible waste, and the sediment and foreign matter discharged to the bottom after sorting is transported on a conveyor belt again, and re-selected in the non-combustible reduction sorter 132, Sorting of combustible waste is done.

As shown in Figs. 7 to 9, the non-combustible reduction sorter 132 is a cylindrical sorting drum, and a plurality of through holes are perforated on the outer circumferential surface to sort and load the soil, as well as to sort and discharge the combustible waste at the end. A plurality of landslides 141 are individually mounted on the cylindrical sorting hole 140 along the outer circumferential surface formed in a cylindrical shape so that the unsuccessful earths and stones fall to the bottom by the weight of the earths and can be sorted and loaded. Since the earth and stone falling piece 141 is made of an elastic material, it is possible to return to its original state by elasticity even if it is bent downward.

That is, as shown in the use state of Fig. 8, when sorted through the non-flammable reduction separator 132 and discharged to the end, when the earth and stones discharged to the earth and stone dropping piece 141 mounted on the cylindrical sorting hole 140 are settled, , The earth and stone dropping piece 141 does not withstand the weight of the earth and is tilted downward to sort the earth and then discharge it to the discharge conveyor belts 142 and 143 installed at the lower part and transport.

At this time, the non-combustible reduction sorter 132 is formed to be inclined to the front, and a hot air fan (F) is also installed at the entrance to dry the sorted combustible waste.

And, as described above, depending on the site conditions, in order to re-select the sediment sorted by the double trommel sorter 20 that accurately sorts the combustible waste in the second, the fine soil separator 11 is replaced with the double trommel sorter 20. It is additionally installed at the rear of the machine to sort out soil and combustible waste less than 25mm. At this time, the sorted combustible waste is transferred to the secondary reduction sorting machine 131 by riding a conveyor belt along with the combustible waste sorted by the double trommel sorter 20 that precisely sorts the flammability in the second.

In addition, in order to accurately select the combustible waste mixed in the soils selected by the primary and secondary reduction separators 131 and 132, a non-combustible reduction separator 132 is additionally installed at the rear of the secondary reduction separator 131. Installed.

After separating and discharging soil and foreign substances from the primary and secondary flammability reduction separators 130 and 131 and the incombustibility reduction separator 132 of the pretreatment process (S1 to S5), and reducing combustible waste, the conveyor belt Ride and merge, and go through the quantitative supply cooperative (S2) and the compression cutting and crushing process (S3), and through the crushing and magnetic selection process (S4 and S5) to sort out crushing and metal, to the combustible fuel conversion screening device 900, which is a post-treatment facility. Supply and transfer.

As described above, the present invention does not selectively process combustible waste by directly inputting combustible waste into the combustible fuel sorting device 900, which is the present process, but first, soils and foreign matter mixed into combustible waste through the pretreatment sorting and reducing device 200, Since the maximum reduction and sorting, the coarse malignant waste is crushed and the metal is separated and transferred to the combustible fuel sorting device 900, which is the main process of the post-treatment facility, the efficiency of sorting combustible waste can be further improved.

However, if the collected combustible waste is dried and sorted through a combustible fuel sorting system without a pretreatment process, as in the prior art, the soil or fine powder mixed with the combustible waste cannot be completely separated and sorted. You will not be able to get combustible waste.

2. Quantitative supply process (S2)

Quantitative supply process (S2) separates the combustible wastes pre-selected in the pretreatment, sorting and reduction process (S1) from crushing and metal, and the compression cutting and crushing device 410, which is a post-treatment facility, and the primary and secondary crushing magnetic separation device ( 300, 400) and when supplying to the combustible fuel sorting device 900, by supplying quantitatively so that the sorting work is carried out continuously without being subjected to irregular overloads, the loss of operating time is prevented, and work efficiency is improved, repair costs, etc. This is to help prevent loss of power.

That is, the sorted combustible waste is injected into the hopper 31 of the quantitative supply device 30 through an excavator or a loader.

As shown in FIGS. 10 and 11, the quantitative supply device 30 is equipped with a quantitative supply means 35 at the lower part of the hopper 31 for injecting combustible waste, and the quantitative supply means 35 The two buckets 32, 33, and 34 are in close contact with each other to be combined.

In addition, cylinders 36, 36a, and 36b are mounted on both sides of the bucket, respectively connected to the buckets 32, 33, and 34 to drive opening and closing of the buckets 32, 33, and 34. .

In addition, the hydraulic unit 37 for controlling the driving of the cylinders 36, 36a, 36b is also mounted under the transfer means 38 to be described later so as not to be interfered with the moving direction of the transfer means 38. . In addition, in order to transport the combustible waste discharged to the bottom by the opening of the buckets 32, 33, 34, a transfer means 38 is installed at the bottom of the buckets 32, 33, and 34. It is formed so that waste can be supplied quantitatively.

The combustible waste sorted as described above is put into the hopper 31 of the quantitative supply device 30. At this time, the opening/closing time of the quantitative supply means 35 mounted at the lower part of the hopper 31 is input to the hydraulic unit 37 in advance.

In this way, when combustible waste is put into the hopper 31, it falls into the plurality of buckets 32, 33, and 34 mounted under the hopper 31.

When the combustible waste introduced into the hopper 31 falls into the buckets 32, 33, and 34 in this way, the cylinders 36, 36a, 36b are moved forward and backward by the drive of the hydraulic unit 37. While doing the opening and closing of the buckets 32, 33, 34 mounted on the lower part of the hopper 31, the operation is performed. At this time, in order to supply the combustible waste into the hopper 31 in a quantitative amount, the buckets 32, 33, and 34 are closed before the combustible waste is input and supplied.

And looking at the opening and closing state of the buckets 32, 33, and 34 of the quantitative supply means 30, the buckets are sequentially shown in Fig. 11 (32-33-34-32-33-34). By repeatedly opening and closing the phosphorus operation, the combustible waste injected into the hopper 31 is continuously quantitatively supplied.

First, when the respective cylinders 36, 36a, and 36b are driven by the drive of the hydraulic unit 37, the cylinder 36 mounted on the rear bucket 32 shown in FIG. 5 moves backward and By slowly opening the bucket 32, combustible waste is supplied in a fixed amount.

In addition, after dropping and supplying the combustible waste to the transfer means 38 under the bucket 32, when the cylinder 36 advances and pushes the bucket 32, the bucket 32 is closed.

At the same time, in order to open the bucket 33 in the central portion, the cylinder 36a mounted on the bucket 33 in the central portion moves backward and slowly opens the bucket 33 in the central portion to supply the combustible waste in a fixed amount.

In addition, after dropping and supplying the combustible garbage to the transfer means 38 under the bucket 33, the bucket 33 is closed when the cylinder 36a advances and pushes the bucket 33.

At the same time, in order to open the front bucket 34, the cylinder 36b mounted on the front bucket 34 moves backward while slowly opening the front bucket 34 to supply combustible waste in a fixed amount.

In addition, after dropping and supplying the combustible waste to the transfer means 38 under the bucket 34, the bucket 34 is closed when the cylinder 36b advances and pushes the bucket 34.

As described above, when the rear bucket 32 is opened and closed in the drawing, the inside of the bucket 32, 33, and 34 by repeatedly opening and closing the bucket 33 and the front bucket 34 in sequence. It is possible to continuously supply the combustible waste input to the combustible waste into the combustible fuel conversion device 900, which is a subsequent treatment facility, in a quantitative amount.

Due to the operating principle of the quantitative supply device 30 as described above, irregular garbage having a large length is cut by the opening and closing movement of the bucket, so that a certain amount can be continuously supplied without being caught or coiled.

As described above, the present invention provides a quantitative and continuous supply of combustible waste to be transferred to the combustible fuel sorting device 900, thereby sorting while maintaining the continuity of work without irregular overload on the combustible fuel sorting device 900 You can do the work.

However, as in the prior art, if combustible waste is directly fed into the primary shredder of the combustible fuel system through the hopper, since it is supplied irregularly without quantitative supply, if a large amount of combustible waste is supplied, it will be blocked or overload the primary shredder. There is a problem that the cause of the failure occurs due to the problem. In addition, as the amount of combustible waste supplied to the hopper is adjusted, the amount of combustible waste supplied to the excavator or loader is inputted at a time difference, so there is a problem that the continuity of the sorting operation cannot be maintained, resulting in a decrease in productivity and equipment cost. This is the amount of over-investment.

3. Compression and crushing process (S3)

The waste supplied from the quantitative supply device 30 as described above has a high moisture content and the poor combustible waste is transferred to the compression cutting and crushing device 410 again to be cut and crushed in a random shape, and then the primary crushing and magnetic separation device (S4) ).

The compression cutting and crushing device 410 is a compression chamber 414 by a compressor 413 that horizontally moves the combustible waste inputted into the hopper 412 of the main body 411 as shown in FIG. 16. When it is compressed and moved forward, it is horizontally cut by the first horizontal cutters 415 installed on both sides of the front body 411, and the horizontally cut combustible waste is moved forward by the compressor 413 again. It is cut again horizontally by the second horizontal cutters 416 installed on both sides of the main body 411.

As described above, the combustible waste cut by the first and second horizontal cutters 415 and 416 is moved forward by the compressor 413 and is vertically cut by the vertical cutter 417 installed in the front.

At this time, since the crushing blade 418 is mounted on the side surfaces of the first horizontal cutting machine 415, the second horizontal cutting machine 416, and the vertical cutting machine 417, the combustible waste is cut at a right angle during horizontal and vertical cutting. The malignant trash of 299M~300M is shredded.

Therefore, the combustible waste cut to less than 300mm and transported is discharged to the discharge port and transferred to the primary crushing and magnetic sorting device (S4) on a conveyor belt.

Further, since a blocking plate 419 is formed on the upper side of the compressor 413, when the compressor 413 moves forward and compresses the combustible waste injected into the hopper 412 in the compression chamber 414, the compressor 413 ) Together with the blocking plate 419 moving forward and closing the outlet of the hopper 412, preventing combustible waste from flowing into the interior of the main body 411 when compressed.

Therefore, when the compressor 413 moves to the rear after compression is finished, the blocking plate 419 also moves backward and opens the outlet of the hopper 412, so that the combustible waste is returned to the inside of the main body 411 through the hopper 412. It is an inflow.

In addition, the compressor 410, the first and second horizontal cutters 415 and 416, and the vertical cutter 417 are connected to the piston of the hydraulic cylinder connected to the hydraulic unit by a hydraulic unit, so that it can be moved forward and backward horizontally and vertically. It will move.

4. 1st crushing and magnetic selection process (S4)

Since the combustible waste conveyed through the above-described compression cutting and crushing device 410 is mixed with bulky foreign substances such as large metal products or wood products, the primary crushing and magnetic separation device 300 to facilitate sorting. First, it is crushed to a large standard.

That is, by using the primary shredder 40, the garbage having a large volume and length is crushed to a size of about 100 to 300 mm. At this time, the primary crusher 40 may use a generally known crusher, but in the present invention, an endless continuous crusher capable of applying a continuous force was used as follows.

As shown in FIGS. 12 and 13, the primary crusher 40 includes shredding blades 45 and 46 on a pair of rotating shafts 43 and 44 formed parallel to each other inside the main body 42. Install at intervals.

Then, by inserting the crushing blade 46 at an interval between the crushing blade 45 and the crushing blade 45, the crushing blades 46 are mounted to be staggered. Accordingly, the crushing blade 45 and the crushing blade 46 are configured to cut the combustible garbage at the intersection (X).

At this time, the crushing blades 45 and 46 are formed with a plurality of locking projections 45 ′ and 46 ′ at intervals on the outer circumferential surface so as to cut combustible waste, so that the locking projections 45 ′ and 46 ′ rotate. As a result, the combustible waste is collected inward and cut at the intersection (X).

The operating state according to the above configuration is a plurality of crushing blades each mounted at regular intervals on the rotation shaft 43 that is decelerated and rotated by the reducer S by receiving the power of the motor M and the rotation shaft 44 meshed with a gear. (45) (46) face each other and rotate inward, staggering. At this time, the combustible garbage is introduced from the outside of the body 42 to the center of the inside by the locking projections 45' and 46' formed protruding from the outer circumferential surfaces of the crushing blades 45 and 46, respectively rotating inward. (45) Combustible garbage is cut at the intersection (X) where (46) crosses.

In addition, since the combustible waste crushed by the primary crusher 40 is mixed with various metals as well as soil, metals must be separated and sorted in order to sort out high-quality combustible waste.

Therefore, in order to sort and separate metals mixed in combustible waste, the metal is separated and sorted by using the primary magnetic sorter 50 mounted in front of the primary crusher 40. At this time, the primary magnetic separator 50 uses an electromagnet or a permanent magnet.

Therefore, the combustible waste from which the metals are separated and foreign substances such as soil are transported through the conveyor belt to the secondary crushing and magnetic sorting device 400 installed in front.

5. Secondary crushing and magnetic selection process (S5)

The combustible waste that is first crushed and transported and the combustible waste of 150 mm or more returned from the first combustible waste sorting process (S6) are secondarily crushed to a size of 100 to 150 mm using the second shredder 41 again. In addition, the secondary magnetic separator 51 is used to sort the metals in order to sort out the metals remaining without being sorted in the combustible waste.

As shown in Figs. 14 and 15, the secondary crushing machine has crushing blades 55 and 56 spaced apart from a pair of rotating shafts 53 and 54 formed parallel to each other inside the main body 52. To form. In addition, the crushing blade 56 is inserted between the crushing blade 55 and the crushing blade 55 to be mounted alternately with each other.

Therefore, the combustible waste is configured to be cut at the intersection (X') where the crushing blade 55 and the crushing blade 56 intersect.

At this time, the crushing blades 55 and 56 are formed with a plurality of protruding blades 55 ′ and 56 ′ at intervals so that combustible waste can be cut to the outer circumferential surface of the protruding blades 55 ′ and 56 ′. Combustible waste is cut by the rotation of.

In addition, a plurality of crushing blades 55a and 56a are combined with a plurality of crushing blades 55a and 56a, respectively, to a rotation shaft 53a and 54a mounted at an angle of 45 degrees to the outer side of the upper side of each of the crushing blades 55 and 56. do. At this time, the crushing blades installed on the upper rotating shafts 53a and 54a between the crushing blades 55 and 55 and crushing blades 56 and 56 respectively formed on the lower rotating shafts 53 and 54 (55a) and (56a) are formed by inserting them alternately. In addition, a plurality of locking projections 55a' and 56a' are formed on the outer periphery of the crushing blades 55a and 56a at intervals in the rotational direction, respectively.

Therefore, the combustible waste flowing into the main body 52 is attracted to the inside by the locking jaws 55a' and 56a' while the crushing blades 55a and 56a on the upper side rotate and rotates to the inside of the lower side. Combustible trash is configured to be cut at the intersection point X'by the protruding blades 55' and 56' of the crushing blades 55 and 56.

The operating state according to the above configuration is a lower rotation shaft engaged by a gear with two rotation shafts 53a and 54a that are decelerated and rotated by a speed reducer (S) (S') by receiving the power of the motor (M) (M'). (53) (54) rotate inward to each other.

At this time, the crushing blades 55a and 56a formed on the rotation shafts 53a and 54a are formed with a plurality of locking projections 55a' and 56a' in the rotational direction, so that they flow into the interior of the main body 42. The combustible waste is caught by the locking jaws 55a' and 56a' and is pulled inward, which is the rotational direction of the crushing blades 55a and 56a, and flows into the center.

Therefore, when the combustible waste flowing into the inner center rotates while the plurality of crushing blades 55 and 56 each mounted at regular intervals face each other by rotation of the rotating shaft 53 and 54, they are alternately rotated inward. , Combustible garbage is crushed and cut smoothly by the protruding blades 55 ′ and 56 ′ of the crushing blades 55 and 56 at the intersection point X′ intersecting each other.

In addition, since the mesh net 57 is mounted in an ellipse under the crushing blades 55, 56, 55a, 56a mounted on the rotating shaft 53, 54, 53a, 54a, As the crushing blades 55, 56, 55a, and 56a rotating close to the mesh mesh 57 rotate, the combustible waste cut at the intersection X is in close contact with the mesh mesh 57, crushed and discharged. Let it. In addition, the combustible waste that has not been discharged is crushed again by the rotation of the crushing blades 55, 56, 55a, and 56a to be discharged through the mesh net 57.

In this way, since the combustible waste crushed by the secondary shredder 41 is mixed with various metals as well as earth and stone, the metals must be separated and sorted in order to sort out high-quality combustible waste.

Therefore, in order to sort and separate the metals mixed in the combustible waste, the metal is separated and sorted using the secondary magnetic separator 51 mounted in front of the secondary crushing machine 41. At this time, the secondary magnetic separator 51 uses an electromagnet or a permanent magnet.

The combustible waste shredded below a certain standard as described above is transferred to the primary combustible waste sorting device 500 for reducing the amount of combustible waste installed in the front.

6. First combustible waste sorting process (S6)

Since the combustible waste that is crushed to a size of 100mm to 150mm and the metals are sorted and transported is mixed with soil, soil, and ash, the double trommel sorter 60 and the combustible material sorter 70 are used. A process is carried out to selectively acquire high-quality combustible waste by separating foreign matters such as soil and combustible waste by size in two stages.

That is, when the combustible waste crushed and transported passes through the double trommel sorter 60, as shown in FIGS. 5 and 6, through the through hole 21a of the internal sorting drum 21, the soil and sand of 150 mm or less are removed. After sorting, the soil of 50 mm or less is sorted through the through hole 22a of the external sorting drum 22.

As described above, the relatively large volume of combustible waste of 150 mm or more is transferred back to the secondary crushing and magnetic sorting device 400 by riding a conveyor belt to perform sorting again.

In addition, the combustible waste separated by separating the soil of 50 mm or less is transferred to the drying device 80 installed in front of the conveyor belt.

In addition, the double trommel sorter 60 is configured by integrally combining an inner sorting drum 21 with a large through-hole 21a of the perforated net and an outer sorting drum 22 with a small through-hole 22a of the perforated net. As the process proceeds sequentially in one body, it can be installed in a confined space, has high sorting efficiency, and precisely sorts combustible waste.

In addition, foreign matters such as soil, etc., selected to be less than 50mm, are transferred to the combustible material sorter 70 by riding the conveyor belt again, and foreign matters such as soil and sand remaining in the combustible waste are sorted and loaded into 18mm or less.

7. Drying process (S7)

As shown in FIGS. 17 to 19, when the combustible waste sorted and transported by the primary combustible waste sorting device 500 is put into the hopper 81a formed on the body 81 of the drying device 80, multi-stage The mesh conveyor belt (82) (83) (84) (85) (86) mounted as a hot air pipe (82a) (83a) (84a) (85a) (86a) and a hot air spray rod are transferred from the top to the bottom. (82b)(83b)(84b)(85b)(86b) It dries quickly while vortexing and swinging motion by the hot air sprayed from it.

That is, in the drying apparatus 80, a hopper 81a is formed above the main body 81, and a rotary injector 81b is mounted below the hopper 81a. Since the rotary injector 81b has a plurality of protruding protrusions 81c on the outer circumferential surface, combustible garbage is accumulated inside the hopper 81a by rotating the combustible garbage input by the rotation of the protruding protrusion 81c. It is configured so that it can be injected continuously while controlling the amount to be injected.

In addition, mesh gun bayer belts 82, 83, 84, 85, and 86 are mounted in the body 81 in multiple stages. At this time, the multi-stage mesh conveyor belt 82, 83, 84, 85, and 86 is installed to transport combustible waste by dropping it from the top to the bottom in a D-shape.

In addition, the mesh conveyor belts 82, 83, 84, 85, 86 are transported forward after drying the floating combustible waste by vortexing and swinging motion by putting hot air into the entrance in the direction of rotation. The hot air pipes 82a, 83a, 84a, 85a, 86a are installed, and the inside of each mesh conveyor belt 82, 83, 84, 85 and 86 Thread rods 82b, 83b, 84b, 85b, 86b are formed in the longitudinal direction, and hot air is blown on the upper surface of the injection rods 82b, 83b, 84b, 85b, 86b. A number of injection nozzles 82c, 83c, 84c, 85c, and 86c are perforated for vertically spraying to promote the oscillating motion of the combustible waste and to lift it for convenient transportation forward while drying. In addition, soil other than the combustible waste that is sorted and transported is discharged to the soil discharge port 87 while falling downward through the holes formed in the mesh conveyor belt 82, 83, 84, 85, and 86. In addition, the combustible waste is discharged through the discharge port 81d on the mesh conveyor belt 82, 83, 84, 85, and 86.

In this way, the combustible waste flowing into the hopper 81a of the drying device 80 is prevented from congestion by the rotation of the rotary inlet 81b mounted under the hopper 81a, and at the same time, the input amount is adjusted and injected .

Therefore, when the combustible waste introduced through the rotary inlet 81b is transported forward by riding the mesh conveyor belt 82 installed on the upper part of the main body 81, it is floated by the hot air sprayed from the hot air tube 82a, causing a eddy current phenomenon. The drying is accelerated while hitting a swinging motion by the hot air sprayed upward through the spray nozzle 82c of the hot air spray rod 82b mounted inside the mesh conveyor belt 82.

In addition, foreign substances such as soil mixed with the combustible waste transported on the mesh conveyor belt 82 fall downward through the holes of the mesh conveyor belt 82.

In this way, the combustible waste is transferred sequentially from the upper side to the lower side on the mesh conveyor belt 82, 83, 84, 85, 86, and the hot air pipe 82a, 83a, 84a, 85a ( Hot air sprayed from 86a) and hot air sprayed upward through the spray nozzles 82c, 83c, 84c, 85c, 86c of the hot air spray rods 82b, 83b, 84b, 85b, 86b Drying is promoted through vortex and rocking motions, and at the same time, foreign matter such as soil falls downward through the holes of the mesh conveyor belts 82, 83, 84, 85, 86, and the soil discharge port 87) is discharged to the outside by a transfer screw 88 mounted therein, and the sorted combustible waste is transported through a conveyor belt through the discharge port 81d.

In addition, the hot air is the hot air obtained by heating the heat blown from the blower 89 by the heater 89a, and the hot air pipes 82a, 83a, 84a, 85a, 86a and the hot air spray rods 82b and 83b ) (84b) (85b) (86b) to transfer and spray.

In addition, on one side of the main body 81, the hot air sprayed from the hot air tubes 82a, 83a, 84a, 85a, 86a and the hot air spray rods 82b, 83b, 84b, 85b, 86b An inlet 81e for recovery is formed, and a filter is attached to the inlet 81e to remove foreign substances and only hot air flows in, and the recovered hot air is exchanged through a heat exchanger 89c through a condenser 89b. After that, after dehumidifying the moisture introduced by the hot air in the dehumidifier 89d, the hot air is again blown through the blower 89 through the hot air pipes 82a, 83a, 84a, 85a, 86a, and the hot air spraying rod ( It is possible to improve thermal efficiency by circulating and recycling 82b) (83b) (84b) (85b) (86b).

In the present invention, the mesh conveyor belt 82, 83, 84, 85, and 86 are formed in five stages inside the main body 81, but depending on the site conditions, 3 stages of 5 stages or less or 5 stages or more It is installed in 5 stages to multiple means so that soil and combustible waste can be dried and sorted.

And as described above, the dried and sorted combustible waste is transported by riding a conveyor belt to the vibration and striking device 100 for secondary reduction work installed in front.

In this way, even in the drying process (S6) according to the present invention, the drying time can be shortened because the inflammable waste transported horizontally by the hot air is sprayed back to the upper side in the vertical direction and dried by a vortex motion and a swinging motion. have. In addition, since the combustible waste is transported through the mesh conveyor belt, foreign matter such as soil mixed with the combustible waste falls through the holes formed in the mesh conveyor belt and sorted during transport, thereby improving the sorting efficiency.

However, the prior art of the related art applies heat to the inside of the body through a heater from the outside of the cylindrical body and heats the internal temperature to 120~200℃. It only dries the combustible waste and does not require additional sediment sorting. Could not be maximized. In addition, since it was dried using a heater, there was a fire problem and it was not economical due to the high consumption of electricity.

8. Secondary combustible waste sorting process (S8)

Since the combustible waste dried and transported by the drying device 80 is still attached without being completely sorted out, the vibration and striking device 100 is configured as shown in FIGS. 19 and 20 to completely sort it out. The second combustible waste sorting process (S7) is carried out by transferring to the impact vibration screen 92 and the rotary striker 90 and 91 to completely select and reduce the soil and fine particles by vibration and hitting.

As shown in Figs. 20 and 21, the impact vibration screen 92 vibrates the transferred combustible waste while the eccentricity received from the motor is vibrating up and down, and the soil and fine powder mixed and attached to the combustible waste are removed from the bottom. It is to drop to and select.

In addition, at the upper and lower portions of the impact vibration screen 100, a rotary striker 90, 91 having a plurality of rotary blades 90a and 91a of rubber wire or synthetic resin, respectively, is formed in the longitudinal direction of the impact vibration screen 92 They are installed at intervals in the width direction.

Therefore, the combustible waste selected by the vibration of the impact vibration screen 92 is sorted by repeatedly peeling off the fine powder attached to the combustible waste by hitting the rotor blades 90a of the rotary slab 90 while rotating the combustible waste. At the same time, it is transported forward.

In addition, the rotary blade 91a of the rotary striker 91 installed under the impact vibration screen 92 strikes the lower surface of the impact vibration screen 92, which vibrates up and down while rotating. By preventing the holes from being blocked by foreign substances such as soil, the continuity of work is maintained.

In other words, the impact vibration screen is separated by peeling and separating the fine powder by applying a blow while the rotary blade (90a) of the rotary strike isolator (90) mounted on the upper side to the selected combustible garbage that is transported along the impact vibration screen (92) is rotated. It is discharged to the bottom through the hole of (92).

In addition, while the rotating blades 91a of the rotating strike body 91 mounted under the impact vibration screen 92 rotate, it strikes the lower surface of the impact vibration screen 92 to solve the clogging phenomenon.

In addition, a cover grill 93 is mounted on the upper side of the impact vibration screen 92 to prevent dust and the like generated by peeling off fine particles attached to the combustible waste from scattering to the outside. In addition, since a plurality of viewing windows 94 are formed in the cover grill 93, the operating state of the impact vibration screen 92 can be checked at any time.

As described above, the present invention completely peels and sorts the fine powder attached to the dried combustible waste by vibration by the impact vibrating screen and the blow of the rotary striker (90, 91), so the selection efficiency can be maximized. have.

However, in the prior art of the related art, since only the soil mixed with the combustible waste is separated and sorted by vibration only with the vibrating screen, the fine powder adhered to the combustible waste cannot be completely separated and sorted, so the sorting efficiency is low, and high quality fuel cannot be provided.

As described above, in the present invention, the combustible garbage, which soil and fine particles are sorted by the vibration and strike device 100 consisting of the impact vibration screen 92 and the rotary striker 90, 91, rides on a conveyor belt, and is installed in front of a crusher. It will be transferred to (110).

9. Fracturing process (S9)

As described above, according to the present invention, a process of completely separating and sorting the soil or attached fine powder remaining in the dried combustible waste, and then cutting and pulverizing through the pulverizer 110 is performed.

That is, the combustible waste is pulverized through the pulverizer 110 into a raw material having a size of 50 mm that meets the specifications of Fluff's SRF (non-molded solid fuel).

The crushing machine 110 may be used as long as it is capable of crushing combustible waste.

However, as shown in FIGS. 14 and 15 used in the present invention, the crushing blades 55 and 56 are spaced apart from a pair of rotating shafts 53 and 54 formed parallel to each other inside the main body 52. To form. In addition, the crushing blade 56 is inserted between the crushing blade 55 and the crushing blade 55 to be mounted alternately with each other.

Therefore, the combustible waste is configured to be cut at the intersection (X') where the crushing blade 55 and the crushing blade 56 intersect.

At this time, the crushing blades 55 and 56 are formed with a plurality of protruding blades 55 ′ and 56 ′ at intervals so that combustible waste can be cut to the outer circumferential surface of the protruding blades 55 ′ and 56 ′. Combustible waste is cut by the rotation of.

In addition, a plurality of crushing blades 55a and 56a are coupled with a plurality of crushing blades 55a and 56a to the rotation shafts 53a and 54a mounted at an angle of 45 degrees to the outer side of the upper side of each of the crushing blades 55 and 56. . At this time, the crushing blades installed on the upper rotating shafts 53a and 54a between the crushing blades 55 and 55 and crushing blades 56 and 56 respectively formed on the lower rotating shafts 53 and 54 (55a) and (56a) are formed by inserting them alternately. In addition, a plurality of locking projections 55a' and 56a' are formed on the outer periphery of the crushing blades 55a and 56a at intervals in the rotational direction, respectively.

Therefore, the combustible waste flowing into the main body 52 is pulled from the outside to the inside by the locking jaws 55a' and 56a' while the crushing blades 55a and 56a on the upper side rotate and flows into the center Combustible garbage is cut at the intersection point X'by the protruding blades 55' and 56' of the crushing blades 55 and 56 rotating inward of the side.

The operating state according to the above configuration is a lower rotation shaft engaged by a gear with two rotation shafts 53a and 54a that are decelerated and rotated by a speed reducer (S) (S') by receiving the power of the motor (M) (M'). (53) (54) rotate inward to each other.

At this time, the crushing blades 55a and 56a formed on the rotation shafts 53a and 54a are formed with a plurality of locking projections 55a' and 56a' in the rotational direction, so that they flow into the interior of the main body 42. The combustible waste is caught by the locking jaws 55a' and 56a' and is pulled inward, which is the rotational direction of the crushing blades 55a and 56a, and flows into the center.

Therefore, when the combustible waste flowing into the inner center rotates while the plurality of crushing blades 55 and 56 each mounted at regular intervals face each other by rotation of the rotating shaft 53 and 54, they are alternately rotated inward. , Combustible garbage is crushed and cut smoothly by the protruding blades 55 ′ and 56 ′ of the crushing blades 55 and 56 at the intersection point X′ intersecting each other.

In addition, a mesh net 57 is mounted in an ellipse under the crushing blade 55, 56, 55a, 56a, [0202] mounted on the rotating shaft 53, 54, 53a, 54a Therefore, the crushing blades 55, 56, 55a, and 56a rotating in close proximity to the mesh net 57 rotate, and the combustible waste cut at the intersection X is in close contact with the mesh net 57 Crush and discharge. In addition, the combustible waste that has not been discharged is crushed again by the rotation of the crushing blades 55, 56, 55a, and 56a to be discharged through the mesh net 57.

In addition, foreign substances generated when fine particles such as soil are selected by the vibration and striking device 100, which is the second reduction process described above, and foreign substances such as fine particles scattered to the outside during pulverization in the pulverizer 110 are air pollution. In order to prevent this, it may be installed to collect dust by connecting the dust collectors 120 and 120 ′ to the vibration screen 100 and the crushing machine 110 described above.

As shown in Figs. 22 to 24, the dust collecting devices 120 and 120 ′ have a main body formed with a conical sieve, and an inlet for injecting air in all directions at intervals in the middle of the main body 121 ( 122) is formed, and a discharge port 123 for discharging fine powder such as soil is formed in the lower part. Therefore, it is possible to remove the dust by connecting the dust generating sources (sorting device, crushing device, etc.) in various places where the dust is generated in each of the plurality of inlets 122 by a duct 122a, respectively.

At this time, a blower 122b is mounted in front of the inlet 122 in order to introduce dust from the dust generating source to the inlet 122 of the dust collecting device. That is, when the blower 122b is operated, the dust generated from the dust generating source is sucked in the operation of the fan and guided through the inlet 122a of the dust collecting device 120 through the duct 122a.

In addition, a plurality of cartridge-type filters 125 are mounted on the filter support plate 124a formed by being coupled to the upper side of the cylindrical case 124 formed in the main body 121. In addition, the filter 125 is supported by being inserted into a plurality of insertion holes 124a perforated in the filter support plate 125a. Therefore, it is configured to filter dust or dust flowing between the filter 125 and the filter 125.

In addition, an air discharge pipe 126 is installed inside the filter 125, so that dust or dust attached to the surface of the filter 125 is separated into air discharged through the air discharge pipe 126, and the lower outlet ( 123).

In addition, the air purified through the filter 125 is configured to be discharged through the air outlet 127.

When dust or the like flows through the inlet 122 formed in all directions on one side of the main body 121 by the above configuration, the introduced dust is transferred to the bottom while rotating along the surface of the cylindrical case 124 to the inside of the cylindrical case 124 The dust is attached to the surface of the filter 125 by entering between the plurality of filters 125 and the filter 125 mounted in a plurality of, and the filtered air from which the dust is removed is an air outlet at the top of the main body 121 ( 127).

In addition, the dust attached to the surface of the filter 125 is supplied from the air tank 126a, and the air injected through the air discharge pipe 126 passes through the outer circumferential surface of the filter 125 and is attached to the outer circumferential surface of the filter 125. The dust is removed and discharged to the discharge port 123 at the bottom of the main body 121, and transported and loaded on the conveyor belt 128.

In addition, a ladder 129 and an inspection hole 120a are formed on one side of the main body 121 to climb up the ladder 129 and inspect the interior of the main body 121 through the inspection hole 120a or replace the filter. have.

Therefore, by completely removing fine dust generated in the process of sorting and separating combustible waste, it is possible to reduce pollution of the surrounding environment and produce high-purity combustible waste fuel (SRF) due to dust removal.

In addition, the crushed combustible waste is transported on a conveyor belt to the compression binding device 150 installed in the front.

10. Compression binding process (S10)

As described above, the combustible trash crushed with high purity is passed through the compression binding device 150 to form a rectangular parallelepiped shape, and processed into combustible fuel (SRF) with iron wire or PP wire, and transferred to the wrapping device 800 for packaging.

11. Lapping process (S11)

After packing the combustible fuel (SRF) compressed as described above in the wrapping device 800, the combustible fuel is shipped.

The wrapping device 800 is as shown in FIG. 25. That is, the combustible compressed product 810 compressed by the compressor first is transferred to the wrapping apparatus 800 by riding the conveyor belt 820. The transferred combustible compressed material 810 is a cross-wrapped material 840 is formed in the cross wrap conveyor 830, and the cross-wrapped material 840 is again successively continued from the horizontal wrap conveyor 850 to the horizontal wrap material 860 After forming, the PP bending wrapping material 880 is automatically formed in 5-stage bundles by the PP automatic bending machine 870, and is transferred to the forklift truck conveyor.

At this time, the wrapping device 800 is proven to have price competitiveness because the production cost is lowered by driving all the power transmission using an electric motor, and the power cost according to partial operation is reduced, so that the production cost due to wrapping is low. In addition, it may be considered that the device may be more complex than a hydraulic motor by using off-the-shelf electric motors, but it has the advantage of requiring less manufacturing cost.

Although the technical idea of the present invention has been described above, this is illustrative of a preferred embodiment of the present invention, but does not limit the present invention. In addition, it is a clear fact that anyone of ordinary skill in the art can perform various modifications and imitations without departing from the scope of the technical idea of the present invention.
