Description

Integrated shredding, solid-liquid separation and compression dewatering device for food waste disposal

The present invention relates to an integrated shredding, solid-liquid separation and compression dewatering device for food waste treatment, and more particularly, to a food waste processing apparatus in which the shredding module, the solid-liquid separation module and the compression dewatering module are integrated.

Food waste and / or sewage from kitchens related to human daily life, manure or sludge collected from restrooms, or manure or livestock wastewater from livestock are primarily separated from food waste and sewage purification in each household or industry. It is collected or treated primarily in a facility or septic tank. Thereafter, the object to be treated is transferred to a sewage end treatment plant, a wastewater end treatment plant, a wastewater treatment facility, or the like and finally processed.

However, since the object to be treated such as food waste, sewage, manure, sludge and the like contains a large amount of solids such as sludge, the purification process cannot be properly performed without separating and removing the solids. Accordingly, the purification treatment step includes a solid-liquid separation step for separating water and solids by dewatering sludge or the like.

Thus, as a solid-liquid separation device for dewatering sludge, two endless filter cloth belts are installed to pass through a plurality of rollers, and a belt press for passing sludge between the two filter cloths so that the sludge is dewatered by the rollers. There is a way. In addition, the shaft with the screw blades formed on the outer circumferential surface is rotatably installed on the inner circumference of the filtration cylinder, and the shaft diameter is gradually increased toward the front, so that the volume of the dehydration chamber is gradually reduced, and gradually as the sludge is transported forward. While being compressed, the water in the sludge is separated through the filter cylinder, and a screw press method in which the sludge from which the water has been removed is discharged in a cake state is used.

However, the belt press method or the screw press method described above is a method of dewatering by pressurizing sludge, and the apparatus is complicated and enlarged, so that the manufacturing cost is high and the dewatering takes a lot of time. Moreover, these methods have a problem in that a lot of moisture remains in the cake discharged due to the low dehydration effect.

In order to solve such a problem, in recent years, the apparatus which isolate | separates moisture using the centrifugal force called the decanter type dehydrator has been developed. The decanter type dehydrator can be manufactured in a small size and light weight, and its use range is gradually being widened as a solid-liquid separator having excellent dewatering effect even at a relatively low speed.

However, when the above-mentioned treatment object not only contains solids such as sludge in a large amount of water, but also includes solids having a large size other than sludge, such as food waste, the above-mentioned solid-liquid separator is directly Can't use it.

In this case, since the water in the solid cannot be removed by the apparatus described above, the object to be treated containing the solid in the form of a large size other than the sludge form must undergo a crushing process before the solid-liquid separation process. That is, after crushing the solids in the form of large lumps in the crushing device in the form of sludge, it is put into the solid-liquid separation device to perform the solid-liquid separation, the purification process needs to be performed properly.

The sludge crimping portion 36 formed at the other end downstream of the barrel 30 has a form in which the inner diameter is gradually reduced, and water passes through the wall surface of the crimping portion 36 similarly to the wall surface of the filtration cylinder 22. May be configured as a filter structure in which a plurality of micropores are formed to be filtered. By this configuration, the dewatered sludge conveyed as described above is compressed in the sludge crimping unit 36 and the water remaining in the sludge is separated once more through the wall surface of the sludge crimping unit 36. Accordingly, the sludge is discharged through the sludge cake outlet 130 while the water is once more removed while the sludge is compressed. Solids discharged through the sludge cake outlet 130, that is, the sludge cake may be collected by a collection device separately installed thereunder.

In this case, below the sludge crimping portion 36, a configuration for collecting the water separated second through the wall surface of the sludge crimping portion 36 is required, which is the dehydrating liquid outlet 120 of the solid-liquid separation module (II) It can be connected and discharged with the water separated from the solid-liquid separation module (II).

On the other hand, in place of the sludge crimping portion 36 having a shape in which the inner diameter gradually decreases, the screw shaft 30s whose outer diameter gradually increases from one end portion upstream to the other end portion downstream in the barrel 30 having a constant inner diameter gradually increases. ) Or a screw shaft 30s having a constant outer diameter is installed in the barrel 30 whose inner diameter gradually decreases from one end portion on the upstream side to the other end portion on the downstream side, and the barrel 30 and the screw shaft 30s. It is also possible to form such that the volume of the space 34 between) gradually decreases. This causes the barrel 30 itself to function as the sludge presser 36. Thus, in this case, the barrel 30 can be configured with a filter structure of the type described above, and below the barrel 30, a configuration for collecting water separated secondly through the wall surface of the barrel 30 is required. . The moisture collection configuration may be connected to the dehydration outlet 120 of the solid-liquid separation module II and discharged together with the water separated from the solid-liquid separation module II.

In the above-described embodiment, the solids pulverized in the shredding module I are transferred through the shredding passage 12a, which is an opening formed in the partition 12 that forms the boundary between the adjacent shredding module I and the solid-liquid separation module II. Transfer to solid-liquid separation module (II) with water. In this case, the pulverized passage 12a is too small in size to make it difficult to move the pulverized solids and water to the solid-liquid separation module II, and if the size is too large, solids that are not properly pulverized are transferred to the solid-liquid separation module II. Will move. Accordingly, it is preferable that a plurality of crushed passages 12a are formed while being formed in a size corresponding to the size of solids that can be processed in the solid-liquid separation module II. However, in order to prevent the crushed material passage 12a from being blocked by the solids, the solids removing unit may be provided at the boundary between the crushed module and the solid-liquid separation module.

Referring to FIG. 8, the brush member 11b may be fixed to the fracture rotation shaft 10s at a position adjacent to the partition wall 12 so as to rotate together with the fracture rotation shaft 10s. A brush is formed on a surface of the brush member 11b facing the partition wall 12, and when the solid member is blocked in the crushed object passage 12a formed in the partition wall 12 as the brush member 11b rotates, the brush member 11b may be removed.

This brush member 11b may be installed in addition to the solid-liquid separation module II. That is, the brush member in which the brush was formed is fixed to the surface which faces the partition 12 in the rotating shaft or the scraper rotating shaft 24s of the filtration cylinder 22, and it can remove that the solid thing was clogged in the crushed object passage 12a.

The overall operation of the integrated crushing, solid-liquid separation and compression dehydration apparatus 100 described above is as follows.

When the object to be processed such as food waste is put into the inlet 110 formed at the rear upper part of the shredding module I and the lid is closed, the motor 100 rotates to start the operation of the apparatus 100. The processing object introduced into the shredding module housing 10 through the inlet 110 is mounted on the shredding rotating shaft 10s and rotated on the rotating blade 11 and the fixed blade 13 fixed to the bottom of the shredding module housing 10. Crushed by At this time, since the rotary blade 11 is rotatably installed on the crushing rotary shaft 10s, when the solid object is included in the object to be processed, the object is rotated in a state indicated by a dotted line in FIG. It will be broken or cut. By supplying water into the shredding module housing 10 from the nozzle 114 provided in the shredding module I, it is possible to facilitate movement to the solid-liquid separation module II after shredding and shredding of the object to be treated. When a part of the input treatment object is crushed and moved to the solid-liquid separation module II through the crushed matter passage 12a formed in the partition 12 of the crush module housing 10 together with the water contained therein and the water supplied separately, The object to be disposed on the inclined surface of the inlet 110 is sequentially introduced into the shredding module housing 10 so that the shredding process is continuously performed. At this time, by spraying water from the plurality of nozzles 114 formed on the inclined surface 112 of the inlet 110, it is possible to facilitate the sequential inflow into the shredding module housing 10 of the object to be treated.

When the crushed treatment object and water flow into the solid-liquid separation module II through the crushed passage 12a, the solid matter is attached to the inner wall surface of the filtration cylinder 22 by centrifugal force by the rotation of the filtration cylinder 22, and the moisture is It flows out through the filtration cylinder 22, and flows out. The spilled water is collected downward by hitting the inner wall surface of the solid-liquid separation module housing 20 and discharged through the dehydrating liquid outlet 120. The solid adhering to the inner wall surface of the filtration cylinder 22, that is, the dewatered sludge, is removed by scraping off the scraper 24 in close contact with the inner wall surface of the filtration cylinder 22 by relative rotational movement with the filtration cylinder 22. The dewatered sludge removed is conveyed to the compression dewatering module III by the spirally arranged scrapers 24.

The dewatered sludge separated from the solid-liquid separation module II is introduced into the space 34 between the barrel 30 of the compressed dewatering module III and the screw shaft 30s through the dewatering sludge passage 31. In the space 34 between the barrel 30 and the screw shaft 30s, the dewatered sludge is moved downstream by the screw vanes 32 formed thereon due to the rotation of the screw shaft 30s. The dewatered sludge is compressed while passing through the sludge pressing portion 36 formed on the downstream side of the barrel 30 to remove moisture once more and is discharged through the sludge cake outlet 130.

On the other hand, the dewatering sludge discharged from the sludge cake outlet 130 in a compressed state by removing most of the water in the food waste and minimizing the voids therein, the conveyance module (IV) (not shown) connected to the sludge cake outlet Through the food processing box (not shown). Such a conveying module may be constituted by a conveying screw device or a belt conveyor.
