Description

[Detailed Description of the Invention] An object of the present invention is to provide an apparatus with excellent processing ability for washing, crushing, and shredding sieve residue separated from sewage and the like.

In order to achieve the above-mentioned purpose, the present invention includes a primary crusher that crushes and sends out sieve residue, a washing tank that agitates and washes the sieve residue crushed by the same machine in water using jetted air, and a sieve residue that has been washed with the same type. A secondary shredding machine re-shreds and dehydrates the sieve, and a cutting machine shreds the sieve residue that has been re-shredded and dehydrated using the same machine. This facilitates subsequent processing.

Hereinafter, the present invention will be explained with reference to an illustrated embodiment.
is a waterway for sewage, etc., 2 is a screen provided in the waterway, 3 is a conveyor, 4 is a primary crusher, 5 is a cleaning tank, 6 is a scraping conveyor, 7 is a secondary crusher, 8 is a cutting machine, Reference numeral 9 indicates a discharge conveyor, and reference numeral 10 indicates a skip hoist, each of which is constructed as follows.

One or two water channels 1 are provided in parallel above the quince.

In the figure, two or more waterways are shown in two rows above and below, but these two waterways are drawn in two rows above and below for convenience, as they are arranged in parallel on the same plane instead of in two rows above and below. It is.

The dust scraped by the scraper 21 from the screen 2 of the waterway 1, that is, the sieve residue, is transferred from the discharge port 22 by the transfer conveyor 23, and from the chute 24 to the transfer conveyor 3.
and sent to the primary crusher 4.

The primary crusher 4 includes a receiving plate 41 following the discharge port 31 of the conveyor 3 and a roller 42 that presses against the upper surface of the plate.
The sieve residue thus crushed falls into the starting end of the washing tank 5 from the end of the receiving plate 41 facing the starting end of the washing tank 5.

The bottom surface 5a of the cleaning tank 5 slopes downward from the starting end toward the terminal end, and at the terminal end there is a sloped wall 5c that slopes upward from the rounded bottom 5b that is curved in an arc shape. Water is stored in the tank, and this water flows from the starting end to the ending end in the tank, and is circulated by the pump P through a pipe 51 communicating from the ending end to the starting end.

A water supply pipe 52 is provided above the starting end of the cleaning tank 5, and a plurality of water supply pipes 53 and air jetting pipes 54 are alternately provided below the water surface, and the water supply pipes 52 and 53 supply water for cleaning. The air jet pipe 54 jets out air to agitate the cleaning water in the tank.
Therefore, the sieve residue put into the tank is washed while being stirred.

A scraping conveyor 6 is provided in the terminal end of the washing tank 5 so as to scrape up the sieve residue from the rounded bottom 5b to the top along the inclined wall 5c, so that the sieve residue scraped up is tilted. It is discharged from the discharge port 5d at the upper part of the wall and flows into the chute 5e.
from there to the secondary crusher 7.

In addition to the same receiving plate 71 and rollers 72 as in the primary crushing machine 4, the secondary crusher 7 is further provided with a pressure roller 73 in contact with the slanted lower surface of the roller 72. The crushed sieve residue is further passed between rollers 72 and 73 to be compressed and dehydrated, and then supplied to the cutting machine 8 via a guide plate 74.

The cutting machine 8 is used to shred the sieve residue that has been crushed and dehydrated as described above, and the structure of the machine may be any structure as long as it has the ability to shred empty cans in the sieve residue.

The shredded sieve residue is dropped from a chute 91 to a discharge section 92 by a discharge conveyor 9 from a carry-out conveyor 81, and is thrown into a hopper 11 by a skip hoist 10.

As described above, in the present invention, the mud adhering to the sieve residue scraped up from sewage, etc. is separated from the sieve residue during crushing by the primary crusher, or becomes easily separated, and the mud in the washing tank is removed. Since the washing water is agitated by the jetted air, the flow of water and sieve residue works together to thoroughly wash away the deposits on the sieve residue, and the sieve residue that has moved to the end of the seed line is removed by a scraping conveyor. It is scraped up, dehydrated by roller compression in a secondary crusher, and crushed again, and furthermore, empty cans and the like in the sieve residue are shredded by a cutting machine 8, making subsequent transport and other processing easier. In addition, the shredded material greatly contributes to improving processing capacity, such as by reducing the pretreatment process when sending it to an incinerator for incineration.

[Brief explanation of drawings]

The drawings are explanatory diagrams showing an example of implementing the present invention. 1 is a water channel, 2 is a screen, 3 is a conveyor, 4 is a primary crusher, 5 is a cleaning tank, 6 is a scraping conveyor, 7 is a secondary crusher, 8 is a cutting machine, 9 is a discharge conveyor, 10 is It is a skip hoist.
