DRYING FEED SELECTION SYSTEM FOR DRY EQUIPMENT

The present invention relates to a dry feed sorting system for a dryer facility, and more particularly, to a dry feed sorting machine for a dryer facility capable of producing high-quality feed with even particles and no foreign substances by sorting and pulverizing dried materials discharged from the dryer. It's about the system.

In general, household waste is rapidly increasing due to the increase in income, changes in consumption propensity, and development of distribution structure along with industrial development.

In particular, since most of the food waste generated in the residential area is composed of organic materials, there is a problem in the stabilization of leachate and the ground during landfill disposal.

Therefore, food waste is recycled into compost or feed through reduction through dehydration or drying, and food waste recycling.

However, in the process of converting food waste into resources, excessive energy was used for feed production, resulting in a lot of economic loss.

In addition, in the process of recycling food waste, wastewater containing a large amount of solids that can be recycled is discharged as it is in the process of separating the solids and desorbents of the food waste, causing serious environmental pollution and waste of resources. Since it contains contaminants of

Usually, the dried material discharged from the dryer goes through processes such as a trommel separator, a magnetic separator, and a pulverizer. The increase and the amount of contaminants (waste) have also increased, which has been a hindrance to corporate management due to excessive expenditure on consignment disposal of waste.

In particular, the post-treatment process part 220 is responsible for producing a high-quality feed with a small particle size and uniformity by re-selecting and pulverizing the firstly selected and pulverized solids through the pre-treatment process part 16 .

To this end, the post-processing process part 220 includes a post-processing primary sorter 180, a post-processing secondary sorter 170, a post-processing hopper 200, a post-processing grinder 190, and a post-processing tertiary sorter ( 210) and the like.

The post-processing primary sorter 180 is a circular sorter, which is installed between the grinder 130 and the feed hopper 140, and separates the solids discharged from the grinder 130 from the solids having a relatively large particle size and the solids having a relatively small particle size. After each of the solids are sorted, the solids having a relatively large particle size, that is, the solids that have not passed through, are discharged to the post-processing secondary sorter 170, and the solids that have a relatively small size, that is, the solids that have passed through, can be discharged to the feed hopper 140, respectively. there will be

In addition, the passing solids sent to the feed hopper 140 are stored in the feed hopper 140 so that they can be used as feed.

The post-processing primary sorter 180 is connected to the pulverizer 130 side and the pre-processing screw conveyor 150a, and each post-processing screw is connected to the post-processing secondary sorter 170 side and the feed hopper 140 side. It is connected to the conveyor 150b.

Here, the mesh size of the post-processing primary sorter 180 may be set to about 2.5 to 3.5 mm, preferably about 2.93 mm (eg, a square mesh having a width of 2.93 mm and a length of 2.93 mm).

Accordingly, the solids that have passed through the mesh of about 2.5 to 3.5 mm in the post-processing primary sorter 180 are sent to the feed hopper 140, and the solids that have not passed the mesh of about 2.5 to 3.5 mm are then It is sent to the secondary sorter 170 for processing.

The post-processing secondary sorter 170 is a circular sorter, and the solids discharged from the post-processing primary sorter 180, that is, the unpassed solids that did not pass through the post-processing primary sorter 180, are treated with relatively large solids. and solids having a relatively small particle size, respectively, a relatively large solid, that is, an unpassed solid, is sent to the post-processing grinder 190, and a relatively small solid, that is, a passed solid is sent to the feed hopper 140. each can be discharged.

In addition, the passing solids sent to the feed hopper 140 are stored in the feed hopper 140 so that they can be used as feed.

The post-processing secondary sorter 170 is connected to the post-processing primary sorter 180 side, the post-processing crusher 190 side, and the feed hopper 140 side by each post-processing screw conveyor 150b.

Here, the size of the mesh of the post-processing secondary sorter 170 may be set to about 3 to 4 mm, preferably to about 3.63 mm (eg, a rectangular mesh having a width of 3.63 mm and a length of 3.63 mm).

Accordingly, the solids that have passed through the mesh of about 3-4 mm in the post-processing secondary sorter 170 are sent to the feed hopper 140, and the solids that do not pass the mesh of about 3-4 mm are then It is sent to the processing grinder 190 .

The post-processing hopper 200 serves to store contaminants such as vinyl and bulky foreign substances discharged from the trommel sorter 120 and supply them to the post-processing grinder 190 .

This post-processing hopper 200 is connected to the trommel sorter 120 side and the post-processing crusher 190 side by each post-processing screw conveyor 150b.

The post-processing grinder 190 serves to pulverize impurities discharged from the post-processing hopper 200 , unpassed solids discharged from the trommel sorter 110 , and unpassed solids discharged from the post-processing secondary sorter 170 . will do

In this post-processing grinder 190, contaminants that have been previously consigned are pulverized once more, and solids of a relatively large particle size that did not pass through the trommel sorter 110 and the post-processing secondary sorter 170 Relatively large solids that did not pass through the process are pulverized once more.

Accordingly, it is possible to reduce the amount of contaminants that are finally consigned, and it is possible to secure an amount that can be used as feed as much as possible.

The post-processing grinder 190 is connected to the post-processing hopper 200 side, the trommel sorter 120 side, and the post-processing tertiary sorter 210 side by each post-processing screw conveyor 150b.

The post-processing tertiary sorter 210 is a circular sorter, and is installed successively on the discharge side of the post-processing grinder 190, and this post-processing tertiary sorter 210 compares the solids discharged from the post-processing grinder 190 relative to each other. After sorting solids with a large particle size (e.g., impurities) and solids with a relatively small particle size, The relatively small solids, that is, the passing solids are sent to the pulverizer 130 to serve to be pulverized once more.

The post-processing tertiary sorter 210 is connected to the crusher 130 side and the post-processing screw conveyor 150b.

Here, the size of the mesh of the post-processing tertiary selector 210 may be set to about 6.5 to 7.5 mm, preferably about 6.8 mm (eg, a square mesh having a width of 6.8 mm and a length of 6.8 mm).

Accordingly, the solids that have passed through the mesh network of about 6.5 to 7.5 mm in the post-processing tertiary separator 210 are sent to the pulverizer 130, and the solids that have not passed through the mesh of about 6.5 to 7.5 mm, that is, contaminants can be consigned.

As a preferred embodiment, the mesh size of each sorting network of the post-processing primary sorter 180 , the post-processing secondary sorter 170 , and the post-processing tertiary sorter 210 of the post-processing process part 220 is post-processing. The order of the primary sorter 180 < the post-processing secondary sorter 170 < the post-processing tertiary sorter 210 may be performed.

Accordingly, the solids and/or contaminants that have passed through the pretreatment process part 160 are separated and sorted into solids having a predetermined particle size while sequentially passing through each of the selectors 180, 170, and 210, and finally, the high-quality feed desired by the customer, that is, the particle size. is reproduced as an even and small feed, it is possible to increase the production of high-quality feed, and it is also possible to significantly reduce the amount of contaminants that are relatively consigned.

As an example, the solids discharged through the dryer 100 and the trommel sorter 120 are trommel sorter 110 → magnetic sorter 120 → crusher 130 → post-treatment primary sorter 180 → post The secondary sorting machine 170 → post-processing grinder 190 → post-processing tertiary sorter 210 → As the grain size is made into small feed while repeatedly passing through the circulation line leading to the grinder 130, feed production can be increased, and the amount of contaminants can be relatively reduced by that much.

2 to 11 are perspective, cross-sectional, and side views illustrating a post-processing grinder in a dry feed sorting system of a dryer facility according to an embodiment of the present invention.

As shown in FIGS. 2 to 11 , the post-treatment crusher 190 is an organic waste, for example, unpassed solids discharged from the trommel sorter 110 , that is, the passed solids discharged from the trommel sorter 110 . In contrast, unpassed solids having a relatively large particle size and contaminants discharged from the post-treatment hopper 200, for example, are foreign substances such as vinyl that are separately discharged together with passed solids and unpassed solids from the trommel sorter 110 It serves to pulverize contaminants and unpassed solids discharged from the post-processing secondary sorter 170 together.

Since this post-processing grinder 190 pulverizes not only contaminants but also solids with relatively large particle sizes, internal parts such as hammers and fixed plates are worn out after a certain period of use, so they must be replaced periodically. The cartridge can be separated only when the main body is completely disassembled when replacing the rotating body) There is a disadvantage in this, the present invention provides a post-processing grinder 190 of a new type that can facilitate replacement work by improving the structure of the post-processing grinder 190 .

To this end, the post-processing grinder 190 includes a grinder body 12 as a means for providing a space for grinding unpassed solids and contaminants.

An inlet 10 is formed at the upper portion of the pulverizer body 12 to allow organic waste to enter the pulverizer body, and an outlet 11 is formed at the lower portion to discharge the pulverized material therethrough.

The pulverizer cartridge 18 is installed inside the pulverizer body 12, and the organic waste introduced into the pulverizer body 12 can be finely pulverized by the pulverizing operation of the pulverizer cartridge 18 at this time.

Further, the post-processing crusher 190 includes a crusher cartridge 18 as a means for substantially crushing organic waste.

The crusher cartridge 18 serves to crush or cut the organic waste in a manner that strikes the organic waste using the rotating hammer 17 .

The crusher cartridge 18 includes a shaft 14 connected to the shaft of the motor 13 to rotate, a plurality of fixing plates 15 that rotate together while being fitted and coupled in a coaxial structure on the shaft 14, and the fixing plate 15 ) is composed of a plurality of hammers 17 and the like that rotate together while being coupled through the hammer pins 16 on the .

The crusher cartridge 18 configured in this way can be installed in a structure supported through both ends of the shaft 14 .

For example, the grinder cartridge 18 is located inside the grinder body 12, and in this state, the shaft 14 of the grinder cartridge 18 passes through the side plate of the grinder body 12 (substantially) Bearings 29 extending outside the grinder body 12 (through the cartridge cover installed on the side plate) and having both ends of the shaft 14 positioned in this way installed on the outer frame structure of the grinder body 12 . ) by being supported at both ends, the crusher cartridge 18 can be installed in a structure supported through both ends of the shaft coupled to the bearing 29 .

Therefore, when power is received from the motor 13 and the shaft 14, the fixing plate 15, and the hammer 17 are rotated as a whole, the organic waste entering the inside of the crusher body 12 is the hammer 17. It can be crushed and crushed by hitting it.

In addition, the post-processing crusher 190 includes a motor 13 as a means for providing power for rotation of the crusher cartridge 18 .

The motor 13 is installed in a structure supported on the frame structure from one external side of the grinder body 12, and the shaft of the motor 13 installed in this way penetrates the side plate of the grinder body 12 and extends outward. It is connected to one end of (14) by a coupling (30).

Accordingly, when the motor 13 rotates, the shaft 14 also rotates, and as a result, the entire grinder cartridge 18 rotates, so that the grinding operation can be performed.

Here, unexplained reference numeral 33 denotes a perforated network.

In particular, the present invention provides a structure in which the entire grinder cartridge 18 can be easily removed from the inside of the grinder body 12 or easily inserted into the grinder body 12 .

To this end, a door 20 that can be opened and closed is installed on the front part of the grinder body 12 while being tilted around the lower hinge part 19 .

Therefore, during normal operation of the grinder, the front part of the grinder body 12 is closed while the door 20 is kept closed, and when the grinder cartridge 18 is replaced, the door 20 is opened and opened at the same time. The grinder cartridge 18 can be removed or inserted through the rear opening of the grinder body 12 .

Here, the upper end of the door 20 can be fixed to the grinder body 12 side by a known clamping device (not shown) capable of locking and releasing.

As another embodiment, as a means that can replace the role of the door 20, a cover for opening (not shown) detachable by a bolt fastening structure may be installed on the front portion of the grinder body 12, at this time When the cover for opening is removed from the Edo grinder body 12, an open part with a sufficient area is created in the front part of the grinder body 12, so that the grinder cartridge 18 can be removed or inserted through this place. .

In addition, on both side plates of the grinder body 12 , slide grooves 21 , through which the shaft 14 of the grinder cartridge 18 can be pulled out or put, for example, upper and lower dimensions relatively large compared to the diameter of the shaft 14 . Each of the slide grooves 21 cut in a substantially rectangular shape having a width is formed, and the slide grooves 21 thus formed can be formed in a form that is completely opened toward the rear side of the grinder body 12 .

In addition, cartridge covers 22 in the form of square plates having a relatively large area compared to the area of the slide groove 21 are installed on both side plates of the grinder body 12, respectively, at this time each cartridge cover 22 can be detachably installed on the side plate of the grinder body 12 by a bolt fastening structure while closing the slide grooves 21 formed on both side plates of the grinder body 12 .

Accordingly, when replacing the grinder cartridge 18, open the door 20 installed on the front part of the grinder body 12 downward (or remove the cover installed on the front part of the grinder body), When the bolted portion of the cartridge cover 22 installed on both side plates of the grinder body 12 is loosened, the front part of the grinder body 12 is opened and the fixed state of the side part is released at the same time, and the slide groove 21 A space through which the shaft 14 can escape is secured.

In this state, after separating the perforated network 33 disposed on the periphery of the crusher cartridge 18, the fixed state of the bearing 29 supporting the shaft 14 is released and the shaft 14 is connected If the connection with the coupling 30 is released and the entire grinder cartridge 18 including the bearings 29 and cartridge cover 22 on both sides is pulled out toward the front, the grinder cartridge 18 can be easily removed from the grinder body ( 12) can be separated from the outside.

That is, since the whole grinder cartridge 18 can be taken out by a simple operation of opening the door 20 and releasing the cartridge cover 22, as before, after completely disassembling the grinder body 12, the grinder cartridge 18 Compared to the method of removing the shredder cartridge, it is possible to secure the efficiency of replacement of the crusher cartridge, as there are advantages in terms of working time and manpower.

Of course, even when reassembling the new crusher cartridge 18 or the repaired crusher cartridge 18, push the crusher cartridge 18 into it from the front side of the crusher body 12 to position it, and then insert the cartridge cover ( 22) is assembled and the door 20 is simply closed, so that the reassembly work after replacement can also be completed quickly and easily.

In addition, the post-processing crusher 190 includes a damper 28 as a means to assist the crusher cartridge 18 to more effectively crush organic waste.

The damper 28 is in the form of a square plate and is positioned between the inlet 10 of the grinder body 12 and the grinder cartridge 18 and can be folded back and forth by a pin 31 at the bottom installed on the grinder body 12 side. installed in the structure.

When the damper 28 installed in this way is fully tilted backward while taking an inclined posture of about 45°, the inlet 10 side and one side of the crusher cartridge 18 (eg, a vertical line passing through the center of the crusher cartridge is a reference) As the front side - the left side in Fig. 3) is in an open state, organic waste is directed to this side and sent to the crusher cartridge 18 side, and at the same time, the inlet 10 side and the other side of the crusher cartridge 18 (for example, , the rear side based on the vertical passing through the center of the crusher cartridge - the right side in FIG. 3) is in a closed state, and organic waste is not sent to the crusher cartridge 18 side through this place.

Accordingly, the organic waste entering through the inlet 10 of the crusher body 12 is guided by the damper 28 to one side of the crusher cartridge 18, for example, the crusher cartridge 18 driven counterclockwise. It is pulverized as it naturally descends toward the rotational direction of the pulverizer, and the organic waste that comes up to the other side of the pulverizer cartridge 18 is blocked by the damper 28 to prevent overflow.

As a result, the organic waste introduced into the inlet 10 of the crusher body 12 smoothly while solving problems such as clogging and entanglement of organic wastes in the inlet area of the crusher cartridge 18 using the damper 28 It is possible to ensure a smooth flow of organic waste, such as being able to send it to the crusher cartridge 18 side, and to effectively pulverize the organic waste.

On the other hand, when replacing the crusher cartridge 18, a method of easily separating or combining the fixing plate 15 from the shaft 14 will be described as follows.

The pulverizer cartridge 18 includes a shaft 14, a fixed plate 15, a hammer 17, etc., and pulverizes organic waste using a hammer 17 that rotates after receiving power through the shaft 14 will play a role

To this end, a plurality of fixing plates 15 in the form of a disk are coupled to the outer circumferential surface of the shaft 14 while being fitted in a coaxial structure through the center hole, and the shaft 14 is between each fixing plate 15 at this time. A spacer 32 fitted thereon is disposed to maintain a gap between the fixing plates 15 .

In addition, a plurality of hammer pins 16 arranged in a horizontal direction in parallel with the shaft 14 at an edge portion of each fixing plate 15 fitted and coupled on the shaft 14, for example, at a predetermined interval along the circumferential direction About six hammer pins 16 arranged as .

At this time, since bolts are fastened to both ends of the hammer pin 16 , the hammer pin 16 as well as the hammer 17 can be easily separated when the bolt is released.

Accordingly, when the shaft 14 rotates according to the operation of the motor 13, the fixing plate 15 as well as the plurality of hammers 17 coupled to the ends also rotate, and eventually the rotating hammers 17 strikes the organic waste, so that the organic waste can be pulverized.

In particular, each fixing plate 15 axially installed on the shaft 14 is coupled in a structure that can be easily separated from the shaft side.

To this end, a recess 23 in the form of a square key groove is formed on the outer circumferential surface of the shaft 14 in parallel along the shaft longitudinal direction, and the recess 23 at this time is 180° out of phase on the outer circumferential surface of the shaft 14 and Two rows can be formed.

In addition, a rectangular convex portion 24 is formed on the inner circumferential surface of the shaft penetrating portion of the fixing plate 15, and the convex portion 24 at this time may also be formed in two places with a 180° phase difference on the inner peripheral surface of the shaft penetrating portion.

Accordingly, when the fixing plate 15 is coupled to the shaft 14, it can be coupled while inserting the convex part 24 of the fixing plate 15 along the recess 23 of the shaft 14, and thus the shaft 14 ) and the fixing plate 15 are coupled by an uneven structure, so that the fixing plate 15 can be easily disassembled from the shaft 14 side, and the fixing plate 15 can be easily coupled to the shaft 14 side. be able to

As a result, only the fixing plate 15 to be replaced can be replaced after the fixing plate 15 is separated from the shaft 14 when the fixing plate 15 is unbalanced or damaged when the fixing plate 15 is damaged, saving time related to the replacement of the fixing plate Of course, the cost of replacing parts can be greatly reduced.

That is, in the past, since the shaft and the fixing plate were connected by welding, the entire fixing plate and the shaft had to be replaced when the fixing plate was worn out or some of the fixing plates were damaged. Since only the parts to be replaced can be easily replaced, the working time can be shortened and the cost of replacing the parts can be reduced.

As a preferred embodiment, the dry feed sorting system of the dryer facility according to an embodiment of the present invention includes a circulation duct provided in the post-processing grinder 190, and this circulation duct has air inside the grinder body 12. By creating a flow that can circulate, it plays a role in preventing clogging caused by the pulverized material.

Usually, the grinder cartridge 18 installed inside the grinder body 12 rotates at about 2,000 rpm. At this time, when the air inside the grinder body to which the grinder cartridge 18 belongs is not smoothly discharged, the grinder body 12 The clogging of the pulverized material occurs at the entrance and the perforated network 33 of the , and eventually, the facility operation rate is lowered such as frequent cleaning of the facility as well as the inspection according to the failure of the facility.
