Description

Sealed waste compression storage system {SEALED TYPE WASTE PRESS AND STORAGE APPARATUS}

The present invention relates to an enclosed waste compression storage device, and more particularly, by crushing, compressing and storing wastes containing harmful substances such as asbestos contained in the closed slate collectively in a closed device to scatter and expose harmful substances. It relates to a sealed waste compression storage device that minimizes air pollution caused by and can be completely and safely disposed of.

Asbestos are several natural minerals belonging to the class of silicates with a fibrous structure. Asbestos has high mechanical strength, excellent technical properties such as heat resistance, fire resistance, abrasion resistance, and flexibility, and is inexpensive, so it is a slate plate, water pipe, fireproof coating material, brake pad, gasket, heat insulation plate, rope, packing, filling material for acetylene containers, etc. It has been widely used in the fields of building materials and transportation machinery.

Recently, asbestos has been found to be a factor of many health problems such as asbestos lung, lung cancer, and malignant mesothelioma, and its use is prohibited. Therefore, the asbestos-containing member, which has already been used in a large amount, needs to be urgently disposed of and detoxified. In particular, the dismantling of buildings using building materials containing asbestos is being actively performed, and the problem of treatment of asbestos is becoming serious.

In general, asbestos-containing waste has been treated by simple landfill. However, in recent years, according to the domestic waste management law, in the case of scatterable wastes containing more than a certain weight of asbestos, they are solidified and then buried. Therefore, the asbestos-containing waste must be transported to the landfill, and the asbestos-containing waste must be finely crushed and atomized one by one even when landfilling, so the asbestos-containing material scattered during this process causes fatal harm to the health of the worker. There is a serious problem in that the risk of environmental pollution increases due to scattering or dissipation of asbestos-containing materials during the process.

Korean Patent Publication No. 10-2010-0010242 includes a crusher that strikes and crushes asbestos-containing wastes and a pulverizer that crushes crushed asbestos-containing wastes, and contains asbestos that can more easily atomize crushed asbestos-containing wastes. Disclosed is a waste crushing device. However, since these pulverizers only have the function of pulverizing and micronizing the asbestos-containing waste, they do not have a function to compress or store the micronized asbestos-containing waste, so it cannot solve the secondary pollution problem during transport of asbestos-containing materials. There is.

The present invention is to overcome the problems of the prior art described above, one object of the present invention by integrating a crusher, a compressor, and a storage container for waste containing harmful components such as asbestos-containing waste slate into a closed structure, It can prevent environmental pollution by fundamentally blocking the scattering and exposure of harmful substances such as asbestos.
