Description

[Detailed Description of the Invention] The present invention relates to a bag breaking machine, and its purpose is to effectively break plastic bags and the like, and crush and sieve the contents thereof.

General garbage such as kitchen waste and miscellaneous garbage, excluding large-sized garbage, is generally disposed of and collected in plastic bags.

This waste is made up of a variety of miscellaneous items, some of which can be used effectively and others that cannot.

Therefore, in order to effectively utilize such general waste, it is necessary to break the bag as a pretreatment to release the waste, and then separate the active ingredients in the waste.

When it is required to separate waste by utilizing differences in particle size, specific gravity, or other characteristics without crushing it, various methods and machines have been proposed, but each has its advantages and disadvantages. The current situation is that there is no effective one.

The present invention has been developed in view of the above-mentioned points, and according to the invention, garbage contained in plastic bags, etc. is released by tearing the plastic bag, and then crushed, and then the garbage is separated into particles according to the particle size difference. Therefore, it is possible to effectively perform subsequent processes such as sorting and removing iron materials using a magnetic separator, which is a pre-processing machine for composting waste, or crushing paper materials that are composted materials. Can be done.

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

1 indicates a rotating sieve made of a cylindrical wire mesh or a perforated plate.

Blades 2 extending in the axial direction of the rotary sieve 1 are fixed at regular pitches in the circumferential direction on the inner peripheral surface of the rotary sieve 1.

The blades 2 are in the shape of lifters and are arranged along almost the entire length of the rotary sieve 1.

The rotary sieve 1 has an opening at one end serving as an inlet 3 for the material to be treated, and an opening at the other end serving as an outlet 4 for discharging the material to be treated, and current collecting rings 5 and 6 are arranged around the peripheries of the inlet 3 and the outlet 4 as insulators (Fig. Not shown.

) is fixed via. A heating wire 7 such as a nichrome wire is embedded in each of the plurality of blades 2 through an insulator along the blade edge 2A, and one end and the other end of the heating wire 7 are connected to the current collecting rings 5 and 6, respectively. connected to.

A power source (not shown) is provided for the current collecting rings 5 and 6.

) is provided, and its power supply brushes 8A, 9A are brought into contact with the current collecting rings 5, 6.

On the other hand, a hopper 1 for charging the material to be processed is placed in the receiving port 3 of the rotary sieve 1, which is placed horizontally with the discharge port 4 side facing downward.
There is also a discharge chute 1 for the sieved material at the discharge port 4.
1 and a receiving tank 12 are installed together, and a receiving tank 13 for the unscreened material is arranged below the rotary sieve 1.

Electricity is applied to the heating wire 7 through the power supply devices 8 and 9, and the cutting edge 2A is heated by the heat generated. At the same time, the rotary sieve 1 is rotated by a rotary drive device outside Japan, and the processed material is passed through the hopper 10 into the rotary sieve 1. When material M, such as a plastic bag containing garbage, is thrown in, inside the rotary sieve 1,
At the same time as the plastic bag is torn, the contents released by the bag breakage are crushed and sorted, the under-sieve treated material a is dropped into the receiving tank 13 and the sieved-like treated material A is sent to the discharge chute 1.
1 into the receiving tank 12.

In this case, when breaking bags such as plastic bags, use the blade tip 2 when the bag is hot.
This is effectively achieved by the mutual effect of linear melting on contact with A and the shearing action of the blades 2, and the contents of the garbage are removed by the blades 2 as the rotary sieve 1 rotates. The material is transferred to the discharge port 4 side while being reversed and crushed by the lifting action, and on the way, it is separated into the upper sieve material A and the lower sieve material a.

When this crusher is applied as a pre-processing device for composting waste, it is necessary to reliably remove dangerous substances such as dry batteries mixed in the waste.

For this purpose, the opening size of the rotary sieve 1 is selected to be slightly larger than that of the dry cell.

As a result, the unsieved materials a such as dry batteries and other microbial easily decomposable organic matter are collected in the receiving tank 13, and the collected materials are transferred to a magnetic separator (not shown).

) to sort out and remove dry batteries.

By adopting such a method, the required power is lower than when the entire waste is subjected to a magnetic separator, and not only the capacity of the magnetic separator can be reduced, but also the sorting efficiency is improved.

In addition, the sieved material A contains paper, and this paper is useful for improving yield and controlling moisture when used as a compost raw material, but this paper is crushed to a particle size suitable for fermentation. However, if it is necessary to separate the waste into paper and other items after that, it is sufficient to crush only the sieved waste A and separate it, which requires less crushing compared to the case where the entire waste is crushed and then separated. The processing capacity and power of the machine and sorting machine can be small.

As is clear from the above description, according to the present invention, it becomes possible to break plastic bags, crush the contents, and sieve them smoothly and continuously, and by using the present invention, it is possible to smoothly and continuously break plastic bags and the like, crush the contents, and sieve them. It becomes easy to simplify pretreatment for effective utilization and improve economic efficiency.
