Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage disposal device that processes so-called shredder dust after collecting automobile scrap products, home appliances, bulky garbage, etc. and crushing them in a shredder.

Conventionally, to dispose of the shredder dust mentioned above, the shredder dust was generally dumped into a landfill by trucks, etc., but some of the treated material would scatter during transportation, causing environmental health problems. Moreover, it has the disadvantage that it is bulky, making it uneconomical due to high transportation and dumping costs.

In view of the above points, it is an object of the present invention to provide an apparatus that can handle shredder dust easily and economically.

In order to achieve the above object, the garbage disposal device of the present invention includes a casing in which a screw is rotatably driven, and a waste material supply section is connected in communication with the casing.
A cutting blade is attached to the inner circumferential surface of the casing, and a molding part is provided at the conveying end portion of the screw for compressing and molding the processed material by reducing the effective conveying cross-sectional area between the screw and the casing, and It is characterized in that it is provided with a device for taking it out from the molding section.

In other words, we focused on the fact that shredder dust contains a large amount of petroleum products such as vinyl and plastics, and while transporting the shredder dust, we further shred it using a cutting blade and process the shredded product. Compression molding is carried out while being conveyed, and heat is generated by friction between the processed material and the inner circumferential surface of the casing, melting the petroleum products in the processed material and surrounding the molded material with the molten material. The product is cooled and solidified, and the solidified product is taken out as a molded product.

Therefore, the shredder dust can be crushed and compressed to significantly reduce its volume, and the petroleum products contained therein can be effectively used for coagulation and solidification, and the processed material can be solidified without using any coagulation and solidification agent. ,
It is possible to obtain a shaped molded product, which is easy to handle and has a lower bulk than conventional products, which reduces transportation costs and dumping costs for transporting it to a landfill or later use. It is possible to eliminate the scattering of dust during transportation, thereby reliably avoiding deterioration in environmental hygiene.Furthermore, the cost of chemicals for coagulation and solidification is unnecessary, and as a whole, shredder dust can be handled easily and economically. Now I can process it.

Moreover, since crushing, compression, solidification, and molding of the processed material can be performed while transporting the processed material, the shredder dust can be continuously processed and molded products can be taken out, which is advantageous in terms of work efficiency.

In addition, since the shredder dust is further crushed and compressed and solidified, high-density molded products can be obtained, which can be used as aggregates in civil engineering and construction, and as building materials.
Furthermore, when the content of petroleum products is large, various post-uses such as use as fuel are possible, which has the advantage of further improving economic efficiency.

Embodiments of the present invention will be described below with reference to illustrative drawings.

and a second casing 8b on the side of the take-out device 5.

Cutting blades 10 are attached to the inner circumferential surface of the first casing 8a at predetermined intervals in both the circumferential direction and the longitudinal direction, and are configured to crush the material while conveying it.

The second casing 8b has a tapered shape with a smaller diameter toward the downstream side in the direction of conveying the workpiece, and the blade body 9a of the screw 9 is also configured to have a smaller diameter toward the downstream side in the direction of conveyance of the workpiece, and the screw 9 and the second casing 8b In addition to reducing the effective conveyance cross-sectional area between the
The processed material is transported while rotating together with the screw 9, and heat is generated by friction between the processed material and the inner peripheral surface of the second casing 8b, thereby removing petroleum products such as vinyl and plastic contained in the processed material. The molding section 4 is configured to melt and flow the molten material toward the inner circumferential surface of the casing 8b by centrifugal force, and to solidify the molten material to mold the processed material.

A cylindrical eighth casing 8c with an equal diameter and a small diameter is provided in series with the second casing 8b over almost the entire length in the longitudinal direction, and the processed material taken out from the molding section 4 is guided through an equal diameter path of a predetermined length. The structure is such that the material to be processed can be transported and molded and solidified better. A third casing 8c is provided on the inner peripheral surface of the third casing 8c at a predetermined interval in the circumferential direction.
The protrusion 11...
On the other hand, a rod 12 is connected to the shaft end of the screw shaft 9b of the screw 9 so as to be integrally rotatable with the longitudinal axis being deviated from the rotation axis P of the screw 9. , the protruding portion 11
A ventilation hole H is formed by the rotation of the rod 12 on the center side of the molded product whose rotation is prevented by the locking action of the rod 12, and the steam generated due to the aforementioned heat generation is released into the atmosphere, It is configured to prevent the molded product from being ejected due to the pressure of the generated steam.

Removal member 14 formed with retrieval holes 13...
is intermittently driven and rotatable by a motor 15 by 45 degrees at predetermined time intervals, receives the molded product from the third casing 8c into the take-out hole 13, and rotates the take-out member 14 with a predetermined amount accommodated. The take-out device 5 is configured to shear the molded product and sequentially take out a predetermined amount of the molded product. In this take-out device 5, hydraulic cylinders 18 and 19 with pushers 16 and 17 attached are provided on both sides of the third casing 8c, and one of the pushers 16 and 17 is used for compression, and
The other 17 is configured for extrusion and transfers a predetermined amount of the molded product accommodated in the take-out hole 13 to the pusher 1.
6, the final molded product is discharged from the take-out hole 13 by a pusher 17, and transported to a desired location by a chute 20 and conveyor 7. In the figure, 21 indicates a lid that closes the extraction hole 13 other than the location corresponding to the chute 20.

A heating device 23 using an electric heater 22 is attached to the outer periphery of the second casing 8b, and a cooling device 26 is fitted around the heating device 23 and causes cooling water from the cooling tower 24 to flow into the annular flow path 25.

In carrying out the present invention, if there are many pieces of wood or paper and the content of petroleum products is small, the heating device 23
However, if the petroleum product has a large content and can be melted well by frictional heat between it and the casing 8b, the heating device 23 and cooling device 26 may not be used.

To configure the forming section 4, it is only necessary to reduce its conveying cross-sectional area and perform compression processing. For example, the second casing 8b and the first casing 8a may be integrally formed with the same diameter, and the screw shaft 9b may be set in the conveying direction. It may be configured such that the diameter becomes larger toward the lower side.
