Description

TECHNICAL FIELD [0001] The present invention relates to a treatment apparatus for disposing waste batteries,

The present invention relates to a waste disposal apparatus for disposing waste batteries, and more particularly, to a waste disposal apparatus for disposing waste batteries, which uses a specific gravity difference to almost completely separate the residual grid and metallic material of the selected polyethylene, And recovering the reduced amount of pure polyethylene. BACKGROUND OF THE INVENTION

Generally, most of the batteries used for starting the automobile are composed of a synthetic resin case and a separator made of sulfuric acid, lead, lead sulfate, lead monoxide, lead dioxide (paste) and synthetic resin. Since sulfuric acid and lead, which are hazardous substances, are discarded as they are, they cause environmental pollution. Therefore, waste batteries that have reached the end of their life are being recycled by separating, collecting, collecting and regenerating or disassembling them.

For example, waste batteries are subjected to disintegration and separation processes at a designated waste disposal plant. Lead and lead compounds, which are constituents of electrode terminals, electrode terminals, electrode plates and positive and negative electrodes separated, are used as the main raw materials for lead- Other parts attached to the container, ie, the separator, are used as plastics and are disposed of separately.

The method of dismantling a waste battery is divided into a conventional method in which an operator manually dismantles a waste battery and an automation method in which a waste battery is separated using a non-separator (hydraulic separator). In the conventional manual method, And the dismantling work requires a considerable amount of labor and time. Recently, a method using an automated waste battery dismantling system has been mainly used.

A waste disposal system of a waste disposal system automates a series of processes of disposing and disassembling a waste battery. As a prior art related thereto, Korean Patent No. 10-0784440 (Patent Document 1) discloses a waste disposal system in which charged waste batteries are continuously installed A deaerator for removing the iron material by using a deaerator installed at one side of the electrolytic solution removing unit, the electrolytic solution removing unit being disposed at one side of the electrolytic solution removing unit and receiving the electrolytic solution-removed waste accumulator; A crusher installed on one side of the de-ironing unit to supply pulverized storage batteries from which the iron materials have been removed to a crusher installed at one side to crush the crushed and stored crushers; and a crusher installed at one side of the crusher, A drag chain conveyor installed at one side of the primary vibration screen to accumulate paste in the form of sludge supplied with pulverized material having a size of less than 100mesh and installed on the other side of the crusher; And the polypropylene floating on the water is supplied to one side of the recovery means, and the separator and the grid which are settled in the water are transferred to the outlet through the first screw conveyor installed on the inner lower side, The separator and the middle plastic, which are suspended by spraying, And a water separator provided at one side of the hydraulic separator to supply the separator and the heavy plastic and the water and the residual paste supplied to the drag chain conveyor, and the separator passes through the screw conveyor at one side to recover the secondary vibration And a stirring device installed on one side of the drag chain conveyor for stirring the soda ash when the paste is supplied and the soda ash is filled and passing the desulfurized material through the filter.

However, in the dismantling system as in Patent Document 1, polyethylene is recovered by separating polypropylene, grid and polyethylene (separator) from a hydraulic separator and separating water and residual paste through a secondary vibration screen. In this case, Polyethylene contains a large amount of polypropylene, lead (lead), paste, and other useful materials that are not completely separated, so that it is impossible to obtain a pure polyethene resin, and there is a problem that useful resources such as a grid, paste and polypropylene are leaked .

That is, the grid of the waste polyethylene is in the form of a thin net-like structure, and because of the softness of the lead, the polyethylene and the grid are tangled with each other, 0.1 to 2% by weight of the paste, 1 to 5% by weight of the paste, and 50 to 80% by weight of the moisture content.

In order to reduce water content in the waste polyethylene, the storage container is tilted for a long time while the bulk is being stored. However, in this case, separate storage facilities are required and the waste water needs to be separately managed and consumes a lot of time.

In addition, since the paste and the grid are discarded together with the waste polypropylene, there is a problem in that there is a large loss in terms of recycling, and when the waste polypropylene is incinerated, the grid, paste and lead components are buried in the ash residue to cause environmental pollution.

Therefore, it is required to develop a process with a high processing speed for recovery and dehydration of these resources.

1. Korean Registered Patent No. 10-0784440 (published on Nov. 11, 2007)

It is able to maximize the recovery rate by increasing the residence time in the separating and dewatering unit by adjusting the amount of metal to be separated and separated from the dewatering unit and the amount of discharged from the dewatering unit. At the same time, the occupied space can be minimized by the integrated process, and the pollution can be prevented by minimizing the leakage of harmful substances.
