Description

Trommel screen

The present invention relates to a trommel sorter, and more particularly, to a trommel sorter that sorts organic wastes and the like according to particle size by a sorting method using a double perforated mesh drum after drying them.

In general, some of the general waste and landfill waste generated at industrial sites are incinerated, and the rest is mostly landfilled.

However, landfilling of waste has not been a fundamental solution, and landfills that can fill the continuously increasing number of wastes are almost saturated, and due to landfilling, they remain almost permanent pollutants without rotting or decomposing. It is the cause of destruction of the natural environment.

In addition, until now, wastes generated from households and industrial sites have not been classified into household waste, building waste, organic waste, and domestic waste according to the type, but are incinerated and landfilled, so the odor, leachate, and dust contained in the waste have been incinerated and landfilled. The environment around the landfill site is also polluted by pollutants such as other pollutants.

As an example, about 30 to 40% of the total amount of waste currently discharged from households is food waste.

In order to dispose of such food waste, conventional methods such as landfilling, dumping at sea, or incineration have been used.

However, in the case of underground reclamation, there is a problem of securing a landfill site, and soil and groundwater contamination by leachate during reclamation occurs. When dumping in the sea, swarms of fish die, red tides, and marine pollution occur. When incinerated, odor and dust occur. As a result, serious air pollution has occurred, which greatly threatens the living environment and the natural environment.

In order to solve these problems, many processes of processing food waste and recycling it as feed or fertilizer have been developed. In the related art, the food waste treatment process collects food waste from homes and restaurants, and then collects foreign substances from the collected food waste. Removed, crushed and pulverized, then dried and fermented at room temperature are widely used.

When organic waste such as food waste is usually dried and recycled as livestock feed or crop compost, plastics, wooden chopsticks, spoons, etc. mixed with the dried organic waste must be sorted.

Currently, the sorting of foreign substances such as vinyls, wooden chopsticks, spoons, etc. is usually done by the manual operation of the operator. There are many problems, such as an increase in the cost of a product due to an increase in the cost of the product and a decrease in market competitiveness, and the inability to protect the health of the worker due to exposure to the odor.

In addition, general vibratory sorters reduce the sorting ability by blocking the perforation network of the vibrating sorter due to vinyl and fiber materials (grass roots, etc.), yarn tissue, etc., and organic substances such as bone fragments that can be used as feed materials are also converted to incineration waste. As the amount of separated and sorted waste increases, there is a disadvantage that it must be incinerated at a high cost.

On the other hand, a trommel screen is a particle size screening device using a rotating drum equipped with a screening net, and is a facility that forms a perforated network in a large cylinder to sort the input material according to the particle size.

This trommel sorter consists of a cylindrical screen with various calibers to sort the input by particle size, and several blades installed inside help break/shredding envelopes and large objects. Therefore, the trommel sorter can be used in rear-end sorting machines. It plays a role of maximizing the sorting efficiency of each sorting machine by selecting and inputting only suitable specifications.

In the present invention, a trommel sorter with improved structure and performance of Korean Patent Registration No. 10-1940451 『Dried Organic Waste Sorter』, which is based on the sorting method of the trommel sorter as described above, is intended to be devised.

The inner perforated network drum driving unit 19 serves to provide power for rotation of the inner perforated network drum 18 .

To this end, a motor 19a is installed in the motor frame 31 that is located at the rear of the frame 10 and installed just below the upper end, and a driving sprocket 19b is installed on the shaft of the motor 19a installed in this way. At the same time, a driven sprocket 19c is mounted around the outer peripheral surface of the rear end of the inner perforated mesh drum 18, and a chain 19d is connected between the driving sprocket 19b and the driven sprocket 19c at this time.

Accordingly, when the motor 19a is operated, the inner perforated network drum 18 is rotated by the transmission between the driving sprocket 19b and the driven sprocket 19c, and eventually the rotating inner perforated network drum 18 is contained inside Coarse foreign substances in the dry organic waste can be first sorted through the hole.

In particular, the inner perforated net drum 18 includes an inner perforated net drum inner baffle 24a and an inner perforated net drum outer baffle 24b as a means to double the screening efficiency of dry organic waste.

The inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum have a flat iron shape having a certain length, and are welded while maintaining an erect posture on the inner and outer peripheral surfaces of the inner perforated network drum 18 in the flat iron width direction. fixed in a way that

The inner baffles 24a of the inner perforated network drum and the outer baffles 24b of the inner perforated network drum 18 are continuously connected along the longitudinal direction of the inner perforated network drum 18 at regular intervals along the circumferential direction of the inner perforated network drum 18. It can be made of a plurality of arranged pieces.

Even in the case of the inner perforated network drum 18 along the circumferential direction, it can be made of four pieces arranged at intervals of about 90°, and at this time, the inner perforated network drum inner baffle (24a) and the inner perforated network drum outer baffle (24b) are It is desirable to ensure that an interval of about 45° can be maintained between each other.

Here, the inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum can be formed in a form that draws various trajectories.

As an example, as shown in FIG. 4A , the inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum may be formed in a straight line side by side along the longitudinal direction of the inner perforated network drum 18. .

As another example, as shown in FIG. 5A , the inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum form a spiral trajectory along the longitudinal direction of the inner perforated network drum 18. can be done

As another example, as shown in FIG. 6A , the inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum are connected in a straight line in parallel along the longitudinal direction of the inner perforated network drum 18 and end The portion forms an arc (弧) and is curved, that is, it can be formed in an arc (弧) curved form such that the concave portion faces toward the rear of the inner perforated network drum (18).

By having the inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum in this way, the entire perforated surface of the inner perforated network drum 18 can be widely utilized when sorting the dry organic waste with a large particle size. , In the case of reverse rotation with the external perforated network drum 22, the external perforated net drum inner baffle 25 in the external perforated net drum 22 and the inner perforated net drum outer baffle 24b of the inner perforated net drum 18 are reversed with each other It is possible to induce frictional movement by hitting, such as hitting the dry organic waste while it is moving, so it is possible to increase the sorting efficiency by loosening the tangled or clumping dry organic waste.

And, when the inner baffle 24a of the inner perforated network drum and the outer baffle 24b of the inner perforated network drum form a spiral trajectory along the longitudinal direction of the inner perforated network drum 18, the dry organic waste is a spiral baffle As it is guided along the path, it naturally proceeds to the front with the outlet, so that the transport efficiency of the dry organic waste can be increased.

In addition, the inner perforated network drum inner baffle (24a) and the inner perforated network drum outer baffle (24b) are connected in a straight line in parallel along the longitudinal direction of the inner perforated network drum 18, and the end portion forms an arc shape and is bent In the case of having a form in which the dry organic waste is trapped inside the arc shape, it can be stagnated for a certain period of time, and the sorting process by drum rotation continues while it is stagnant, so that the dry organic waste is In contrast to the waste that proceeds forward as it is and exits, the sorting efficiency for dry organic waste can be relatively increased.

In addition, the trommel sorter includes an external perforated net drum 22 and an external perforated net drum driving unit 23 as a means for secondary sorting of dry organic waste.

The external perforated network drum 22 is a medium coarse foreign material contained in the dry organic waste, for example, a relatively coarse foreign material from the selected waste remaining after primary screening by the internal perforated net drum 18. do.

To this end, the outer perforated network drum 22 is in the form of a circular perforated drum having a plurality of holes formed on the circumferential surface, and is arranged concentrically around the outer periphery of the inner perforated network drum 18 and takes a horizontal posture parallel to it The front end and the rear end of the external perforated network drum 22 taking a horizontal posture in this way are installed in a structure supported by the second roll support device 20 installed in the front and rear sides, respectively, at the upper end of the frame 10 .

This external perforated network drum 22 has a relatively large diameter compared to the inner perforated network drum 18 and at the same time has a relatively small hole size compared to the inner perforated network drum 22, and it is possible to select medium thick foreign substances.

At this time, the hole of the external perforated network drum 22 may have a diameter of about 5 to 10 mm, preferably a diameter of about 8 mm.

By adopting a double perforated network consisting of a combination of the inner perforated net drum 18 and the outer perforated net drum 22, it is possible to improve the sorting and discharging ability for each particle size size.

That is, by separating and discharging into a double structure using the inner perforated network drum 18 and the external perforated net drum 22, materials with large and light particle sizes are first selected through the internal perforated network, and secondarily, the particle size is sorted through the external perforated network. By proceeding, it is possible to secure excellent selective discharge capability for dry organic waste.

In addition, a second outlet 21 having a shape corresponding to the overall diameter of the drum is formed at the front end of the external perforated drum 22 for discharging the secondarily sorted waste, and through the second outlet 21 formed in this way Secondary sorting waste can be discharged out of the drum.

In order to support the rotation of the external perforated network drum 22 as described above, the second roll support device 20 for supporting the front end and the rear end of the external perforated network drum 22 includes a bracket 20a installed at the upper end of the frame 10 and this It consists of a roll (20b) which is freely rotatably installed on the installed bracket (20a) and in rolling contact with the outer peripheral end of the external perforated network drum (22).

It serves to support the perforated drum 22 so that it can rotate smoothly.

Here, each of the two brackets 20a and the roll 20b of the front and the rear are arranged with a phase difference of about 90° from each other based on the central axis of the external perforated network drum 22 while stably holding the external perforated network drum 22 be able to support

The external perforated network drum driving unit 23 serves to provide power for rotation of the external perforated network drum 22 .

To this end, the motor 23a is installed in the motor frame 31 installed just below the upper end while being positioned at the rear of the frame 10, and the driving sprocket 23b is installed on the shaft of the motor 23a installed in this way. At the same time, a driven sprocket 23c is mounted around the outer peripheral surface of the rear end of the external perforated mesh drum 22, and a chain 23d is connected between the driving sprocket 23b and the driven sprocket 23c at this time.

Accordingly, when the motor 23a is operated, the external perforated network drum 23 is rotated by the transmission between the driving sprocket 23b and the driven sprocket 23c, and eventually the rotating external perforated net drum 23 is contained inside Medium-thick foreign substances in the dry organic waste can be secondary sorted through the hole.

At this time, the rotational direction of the external perforated network drum 22 can be set in opposite directions to the rotational direction of the inner perforated network drum 18, and thus the external perforated network drum 22 and the inner perforated network drum 18 are connected to each other. As it rotates in the reverse direction, the primary and secondary sorting capabilities of the perforated net drum can be further improved.

In particular, the external perforated net drum 22 includes an inner baffle 25 for the external perforated net drum as a means to double the screening efficiency of dry organic waste.

The inner baffle 25 of the external perforated network drum has a flat iron shape having a certain length, and is fixedly installed by welding or the like while maintaining an erect posture in the horizontal direction of the inner peripheral surface of the outer perforated network drum 22 in the flat iron width direction.

This external perforated network drum inner baffle 25 is continuously connected along the longitudinal direction of the external perforated network drum 22, and at the same time, it can be made of a plurality of pieces arranged at regular intervals along the circumferential direction of the external perforated network drum 22.

For example, the inner baffle 25 of the external perforated network drum may be formed of four pieces arranged at intervals of about 90° along the inner peripheral surface of the outer perforated network drum 22 in the circumferential direction.

Here, the inner baffle 25 of the external perforated network drum can be formed in a form that draws various trajectories.

As an example, as shown in FIG. 4B , the inner baffle 25 of the external perforated network drum can be formed in a straight line parallel to the longitudinal direction of the external perforated network drum 22 .

As another example, as shown in FIG. 5B , the inner baffle 25 of the external perforated network drum can be formed in a continuous form while forming a spiral trajectory along the longitudinal direction of the external perforated network drum 22 .

As another example, as shown in Fig. 6b, the inner baffle 25 of the outer perforated network drum is connected in a straight line in parallel along the longitudinal direction of the outer perforated net drum 22, and the end portion forms an arc shape, It can be made in a curved form, that is, in an arc-shaped curved form such that the concave portion is directed toward the rear of the external perforated network drum 22 .

It is possible to induce frictional motion caused by blows, so it is possible to increase the sorting efficiency, such as loosening and dissolving tangled or clumped dry organic waste.

And, when the inner baffle 25 of the external perforated network drum has a spiral trajectory along the longitudinal direction of the external perforated network drum 22 and is formed in a continuous form, the dry organic waste is guided along the spiral baffle and naturally the front side with the outlet Therefore, it is possible to increase the transport efficiency of dry organic waste.

In addition, in the case where the inner baffle 25 of the external perforated network drum is connected in a straight line in parallel along the longitudinal direction of the external perforated net drum 22 and the end is curved in an arc shape, dry organic waste Being trapped inside this arc shape, it can stagnate for a certain period of time, and even while it is stagnant, the sorting process by drum rotation continues to take place, so that the dry organic waste flows forward as it is. Compared to that, the sorting efficiency for dry organic waste can be relatively high.

On the other hand, in the present invention, the dry organic waste naturally proceeds forward along the longitudinal direction of the inner and outer perforation network without a separate transport means while the sorting is carried out through the internal and external perforated network, so that the selection is made while passing through the entire length of the inner and outer perforated network. to provide.

The position is lowered by ∼10°, and in addition, the tip of the screw 11b of the screw feeder 11 and the tip of the pipe feeder 15 are internally and externally combined with the inner perforated net drum 18 and the outer perforated net drum. It can be positioned only to the inner rear end of (22).

Accordingly, the dry organic waste pushed into the screw feeder 11 after being supplied into the pipe feeder 15 is forcibly transferred only to the inner rear end of the inner perforated network drum 18 and the outer perforated net drum 22, and then It can be selected while being naturally transported forward along the inside of the inner perforated net drum 18 and the outer perforated net drum 22, which are in an inclined posture, and eventually the inner perforated net drum (without a power means for transporting dry organic waste) 18) and the entire length section of the external perforated net drum 22 can be used to sort dry organic waste, thereby increasing the efficiency and sorting ability of the perforated net drum.

In addition, the trommel sorter is a means for transferring to one side the tertiary sorting waste that has passed through the inner perforated net drum 18 and the external perforated net drum 22, that is, the final sorted waste used as feed, etc. ) and a screw feeder driving unit 27 .

The screw transfer device 26 has a circular or rectangular elongated box shape having a screw shaft 26a rotating by motor power while being supported at both ends by bearings, and a sorting waste outlet 26b in the front lower part based on the sorting waste transport direction. It is composed of a transfer case (26c) made of.

Here, the transfer case 26c is installed in a structure coupled to the case chute 32 formed at the lower end of the case 24 in a horizontal posture, and the transfer case 26c installed in this way is the case chute over the entire length. The sorting waste of fine particles that communicates with the case chute 32 and is discharged through the case chute 32 can be put into the transfer case 26c as it is.

Next, the fine foreign material that has fallen into the discharge chute 28 of the external perforated network drum 22, that is, the tertiary sorting waste is introduced into the screw transfer device 26, and the tertiary sorted waste thus introduced is the screw shaft 26a). After being transferred to the front by the rotation of , it is continuously discharged through the waste outlet 26b in the transfer case 26c and can be recovered.

Therefore, the dry organic waste is collected by size such as coarse foreign material, medium foreign material, and fine foreign material while sequentially passing through the internal double mesh drum 18 and the external double mesh drum 22, and then collected and used as reclassification or feed. can become

In particular, during the primary and secondary sorting by the inner perforated network drum 18 and the external perforated network drum 22, the inner perforated network drum 18 has an inner perforated network drum inner baffle 24a and an inner perforated network drum outer baffle 24b In addition, the external perforated network drum 22 is provided with an inner baffle 25 of the external perforated net drum, and these baffles interfere with the dry organic waste while crossing each or each other by the reverse rotation of the drum, and by striking the dry organic waste, drying When sorting organic wastes with a large particle size, the entire perforated surface of the inner and outer perforated network drums 18 and 22 can be widely used, and the dry organic waste can cause frictional motion due to blows, etc. Selection of dry organic wastes efficiency can be increased.

As such, in the present invention, by using a double perforated mesh drum, the screening waste of coarse particles such as vinyls, wooden chopsticks, spoons, grass roots, etc. contained in the dried organic waste, as well as the screening waste of intermediate particles, fine particles that can be used as feed, etc. By providing a new organic waste sorting machine that can classify the sorting wastes of the sorting equipment step by step according to their size, the efficiency of sorting operation can be increased, such as increasing the daily processing capacity of the sorter equipment, and the durability of the sorter equipment can be extended. In addition to this, it is possible to efficiently and economically operate the sorting equipment such as maintenance and repair.

In addition, in the present invention, by providing a new trommel sorter equipped with a baffle that serves to blow and transport dry organic waste to the inner perforated net drum and the external perforated net drum, the selection efficiency is improved by inducing frictional motion by hitting the baffle. can be further improved.
