[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dust crushing device for easily and finely crushing waste such as glass bottles, paper or plastic cups, sardines, containers, bags, etc., or pieces of ceramics.

[0002]

[Prior art]

 Recently, the treatment of food waste discharged from homes and cafeterias has been taken up as a social issue. By the way, normally, garbage is accompanied by mixed water, adhering water, and tissue water. For example, udon soup, miso soup, vegetable soup, curry rice, etc. can be mixed with water, while water with adhered water can be, for example, vegetable scraps after washing with water, pieces of fish or meat, etc. There is. In addition, examples of tissue water include water that constitutes fruit pulp and skin, water contained in vegetable leaves, stems, and water contained in each tissue of animals. Therefore, if the food waste is shredded and shredded, these waters will adhere to the solids or become mixed with the solids. It is necessary to design it so that it can be taken out.

In order to meet such a demand, the present inventor has previously provided the garbage, which is fed from the garbage inlet 2 as shown in FIG. The screw 11 and the cutting blade 14 mounted in the housing 1 are pressed, dehydrated, and crushed and sent to the lid plate 16 to drain the water dewatered from the garbage through the drainage holes 21 to remove the garbage. A garbage processing apparatus (Japanese Utility Model Publication No. 61-4474) having a structure for discharging through a processed material discharging hole 17 formed in 16 and this apparatus, as shown in FIG. A cylindrical second casing (5) having a plurality of rows of crushed waste discharge grooves (6, ...) and multiple drainage holes (7, ...) in the lower half is connected to the lid plate side. In addition, in the second casing (5), the first screw as shown in FIG. The second screw (18) that rotates coaxially with the main unit (11) is mounted, and the pressure plate (19) provided at the end opposite to the cover plate (16) is attached to the shaft of the second rotating shaft (12). A device (Japanese Patent Application No. 9-20488) having a structure in which a load in the direction is supported so as to be adjustable is proposed.

On the other hand, unlike raw garbage, waste that does not substantially contain water, such as glass bottles, paper or plastic cups, sarcasm, packaging containers, bags, etc., is finely cut and crushed. Therefore, the amount handled is also reduced. The device in this case has only to have a function of crushing into fine pieces, and it is not necessary to particularly consider the separation of solid matter and water.

[0005]

[Problems to be solved by the device]

 The present invention has been made for the purpose of providing a crushing device capable of crushing waste efficiently by simply replacing some of the parts of the previously proposed food waste processing device with parts having a simple structure. It is a thing.

[0006]

[Means for Solving the Problems]

 The present inventor has conducted various studies on how to easily convert the previously proposed food waste treatment device into a dust crushing device, and as a result, has identified a second screw 18 and a pressure plate 19 in the device shown in FIG. It was found that the object can be achieved by adopting a structure in which the middle cylinder B having a shape is exchanged, and the present invention has been made based on this finding.

That is, according to the present invention, one end is opened, the other end is closed, and a first rotating shaft (10) and a first rotating shaft (10) are installed in a cylindrical first casing (1) provided with a dust inlet (2) above. A fixed first screw (11) and a cutting blade (14) arranged at the tip of the first screw are rotatably mounted, and a large number of processed product discharge holes are attached at the open end to the cutting blade (14). With respect to the main body fitted with the cover plate (16) having the holes (17, ...), a plurality of crushed waste discharge grooves (6, ...) Are engraved in almost the upper half and a large number in the lower half. The cylindrical second casing (5) having the water drainage holes (7, ...) Is continuously provided on the lid plate side, and is inscribed in the second casing (5) with one end having a ring-shaped outer edge (8). ), And a middle cylinder (B) consisting of a cylinder with a lower half cut out is detachably fitted and fixed. It provides a rubbish crushing device.

[0008]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing a middle cylinder B and a casing portion A 1 before mounting the middle cylinder B in the device of the present invention. The casing portion A shown in FIG. 1 is the same as the casing portion of the previously proposed food waste treatment device (Japanese Patent Application No. 9-20488), and the dust input port 2 is provided at the upper portion in the portion A of this figure. The second casing 5 is connected to the open end side of the first casing 1 having the above through the flanges 3 and 4. The second casing 5 is provided with a plurality of grooves 6 for discharging crushed dust in the upper half of its inner wall, and a large number of drainage holes 7 are formed in the lower half. , ... have been drilled. It is advantageous to construct the second casing 5 such that the upper half and the lower half are separately manufactured and bolted through a flange, but they are connected by screwing, welding or other means. Good.

The middle cylinder B shown in this figure is formed of the same cylinder with one end formed on the ring-shaped outer edge 8 and the lower half portion cut out. The outer diameter of the middle cylinder is almost the same as the inner diameter of the first casing. The middle cylinder is fitted in the second casing, and the ring-shaped outer edge makes close contact with the outer edge of the perforated plate. Is fastened to the second casing through bolt holes of projecting plates 9 and 9'provided on the left and right of the opposite end surface of the ring-shaped outer edge 8. In the casing part A having such a structure, the parts housed in the casing of the previously proposed garbage device (Japanese Patent Application No. 9-20488), that is, the parts shown in FIG. The one without the plate 19 is stored.

That is, inside the second casing 5, a second rotary shaft 12 is provided at the end of the first screen 11 in the first casing 1 so as to rotate coaxially with the first rotary shaft 10. It is fixed. The connecting portion of the second rotary shaft 12 is provided with a square seat 13 for fitting and fixing the cutting blade 14. The cutting blade 14 is fitted into the square seat 13 through a rectangular hole 15 formed in the central portion of the cutting blade 14, and the cutting blade 14 includes the first rotary shaft 10 and the first screw 11. And, it is adapted to rotate coaxially with the second rotary shaft 12. A cover plate 16 having a large number of discharge holes 17, ... Is attached to the cutting blade 14 so as to attach it to the flange 3 connecting the first casing 1 and the second casing 5, for example, a pin. It is supported in a non-rotating state.

The second rotary shaft 12 has a length substantially the same as that of the second casing 5. In the present invention, the second rotary shaft 12 merely plays a role of mounting and fixing the cutting blade 14. When diverted to the processing device, it plays a role of mounting the second screw 18 and the pressure plate 19 and adjusting the load together with the adjusting bolt 20.

The second casing 5 of the present invention is provided with a plurality of crushed dust discharge grooves 6, ... In the upper half of the inner wall thereof, and is shredded by the first screw 11 and the cutting blade 14 and fed. The crushed dust that has flowed out passes through this discharge groove and is discharged from the other end of the middle cylinder B. Further, in the lower half portion of the second casing 5, a large number of water drainage holes 7, etc. for adhering to the material to be crushed and squeezed out of the mixed garbage are pierced. , Are preferably provided in a rectangular shape having a long side / short side ratio of 1.5 to 2 and a short side of 1.0 to 2.0 mm. It is advantageous in terms of processing to form the lower half portion of the second casing 5 into a mesh plate structure having such voids.

Usually, a mesh plate having a right circular hole is used for extracting moisture of this kind, but this has no particular problem during the first time, but the mesh gradually becomes clogged during use. As it will not be possible to dehydrate, it is necessary to carefully clean the holes one by one and remove the clogs, which requires a great deal of labor and time.

Causes of such clogging include glass products such as glass bottles, resin products such as ceramics and food and drink containers, paper products such as paper containers, chicken bones, and fish in crushers and food waste processors. This is because crushed fines such as bones and plant fibers can not firmly enter, squeeze out or return into the right circular hole by the strong squeezing and pressing force of the rotating screw.

This phenomenon will be described by taking fine fibers as an example. As a result, the fine fibers sandwiched from the upper edge to the lower edge of the hole follow the arc as a result of the pressing force being applied to the entire width of the diameter of the right circular hole. It is pressed into multiple layers while gradually gathering at the right end of the circle, and even if each is a soft and weak fine fiber, the whole becomes hard and strong and becomes a resistance block extending from the upper edge to the lower edge. It becomes difficult to pull it out, and the holes are blocked, making it impossible to dehydrate. Moreover, even if this aggregated and consolidated fiber mass is pushed back in the opposite direction in an attempt to clean it, the compressed mass cannot return to the inside.

[0016] Due to the blockage of the mesh formed by the holes of such round holes, the processed material is discharged together with a large amount of water which cannot be dehydrated, and the residue which is almost uncleanable and is blocked by the mesh is a source of a bad smell. It will result in adverse effects such as If the pore size of the mesh is increased by avoiding such an adverse effect, fine particles smaller than the pore size together with the fine fibers, which should not be discharged together with water, such as cooked rice grains, will come out from the mesh in a considerable amount and the dust will be removed. As a processing machine, it will expose a fatal defect. In addition, in order to eliminate this defect, attempts have been made to constantly clean the mesh by using a complicated structure in which the rotating brush makes circulating contact with the outer circumference of the mesh cylinder while pouring water, but none of them failed. The reality is that there have been no successful cases yet.

The water drain hole 7 as a preferred embodiment of the present invention has solved all the above-mentioned inconveniences and defects by making the shape of the hole rectangular. That is, since the directions of the fine fibers sandwiched from the upper edge to the lower edge of the hole are the same direction and are parallel to each other, they change direction along a circular arc like a right circular hole, aggregate and entangle, overlap and compress, and press firmly. There is no need to be.

That is, even if layers of fine fibers are extended in parallel to the same direction and extend to the left, fibers in a straight traveling direction such as a right circular hole and fibers bent inward along both arcs are different from each other. Since it does not become a solid compact that is pushed in by overlapping, it cannot withstand the pressing force that acts from the inside to the outside when it expands to a certain extent and the upper part of the fiber layer collapses to the outside, at that time. Even the lower layer is dragged together and collapsed and discharged, and the fine fiber residue sandwiched from the upper edge to the lower edge of the hole to the extent that it does not collapse can be rubbed in a reverse direction with a brush or the like. Since there is no resistance and it falls off to the outside, no mesh blockage occurs.

[0019] It should be noted that a piece of a piece of mesh that rarely fits into and is caught in the short diameter and width of the hole of a mesh has a margin on the left and right when it is rubbed left and right with a brush, so the piece itself rotates and returns to the inside of the hole. Either way, it will fall out, and in any case, the holes such as the mesh will not remain blocked.

Therefore, according to the preferred drainage hole of the present invention, there is no blockage of holes such as meshes, therefore, the dehydration effect is not affected, cleaning is easily completed, and no residue remains in the casing, Therefore, no odor is generated and it becomes extremely hygienic.

[Action]

 In the field of food and drink, fresh food, and favorite foods, a large amount of disposable waste such as plastic, paper, wooden tableware, packaging containers, folding boxes, glass bottles, pottery containers for cooked rice, etc. are generated. To do. Since all of these occupy a large volume, the actual situation is that they are troubled in their collection and processing.

The present invention is a crushing device suitable for reducing the volume of these bulky wastes, and when these wastes are put into the device of the present invention, they are attached to paper cups, bottles and other various containers. When the container is crushed, cut, or broken by the first screw that rotates in the first casing, the accumulated water immediately flows down to the lower side, and if necessary, the drain pipe provided in the first casing. The water is drained from the container, the container is pushed forward by the action of the first screw, further crushed and granulated by passing through the cutting blade and the perforated plate, and then discharged through the middle cylinder. Also, a bento box made of vinyl, which contains uneaten food waste with water content, is also crushed by the first screw and crushed into fine particles when it is pushed forward while passing through the cutting blade and porous plate. Water is squeezed at the time of liquefaction treatment and by the pressing force to reach the perforated plate, the water flows down in the first casing and is drained from the drain pipe, and the remaining water is drained from the drain hole of the second casing. To be done.

[0023]

[Effect of the invention]

 The waste crushing device of the present invention can be configured simply by replacing a part of the parts of the food waste processing device, thereby reducing various wastes to a volume of 1/8 to 1/10. Therefore, it is very advantageous both economically and efficiently.
