A kind of waste refrigerators disintegrating machine

Technical field

The utility model relates to disintegrating machine, specifically a kind of waste refrigerators disintegrating machine.

Background technology

Waste refrigerators metal, plastics and alveolar layer fuse, and in waste refrigerators recycling process, adopt crushing technologies such as low temperature and normal temperature fragmentation at present.The cryogenic pulverization technology is used liquid nitrogen, make firm parts coolings down about-190 ℃ such as compressor, utilize the black brittleness of iron, make iron and nonmetally efficiently peel off fragmentation, and the normal temperature crushing technology is sorted out respectively big parts such as door of refrigerator body and finding exactly, and the sorting in sorting unit respectively of metal fragment and plastics.But cryogenic pulverization technical equipment required precision height, and complicated operation, the operating cost height is unsuitable for the national conditions of China.In all electric appliance and electronic products, only waste refrigerators is handled the most complicated, processing cost is the highest, even realize that resource also is difficult to support cost recovery and processing cost, the processing of waste refrigerators suffers great loss, so adopt the cryogenic pulverization technology again, only can make originally to make the matter worse, so technology and equipment are difficult to obtain promote in China with regard to the project of losing.

Toshiba household electrical appliances reclaim factory casing are pulverized with alveolar layer, carry out destructive distillation again and handle, by the gas converting means with the angry body of institute at pyrolytic more than 1200 ℃, be used as clean oxidation fuel.According to the character such as be subjected to that magnetic force, density, electricity are led of metal, metal material in the waste household appliances to be carried out mechanical sorting reclaim, particle diameter, shape, the flexibility ratio of the various materials in broken back also is the key parameter that waste refrigerators machinery reclaims technology.The eddy current screening installation successfully is used for the classification and the reclaimer operation of metal beyond several deironing, but for the recovery of waste refrigerators, still need improve.Electrostatic separation technique is to be applicable to the fine grain important isolation technics of particle separation diameter scope at 0.1～5mm, but this technology be used for the metal material of waste household appliances reclaim still immature, and complicated operation.For educational level China on the low side, promote very difficulty.Germany has released a kind of technological process of handling discarded electric appliance and electronic product with beneficiation method.Waste refrigerators can draw various metal values products through pulverizing, magnetic separation and eddy current separation sequence of operations.This beneficiation method is the nature difference according to various components in the discarded object, realizes various components separation.Twice pulverizing, magnetic separation, separation operation have wherein been adopted.Though separation process is complicated, separating effect is better than the handling process of resource flow process.This technological process has obtained bigger popularization in China, but, what wherein the problem of Cun Zaiing need solve is, waste refrigerators extensively is subjected to social concerns because of contained CFC-11 or CFC-12 in its cold-producing medium and the foamed plastic, because CFC is serious day by day to the destruction of ozone layer, so a plurality of countries sign Montreal protocol in September, 1987 in Montreal, CAN, limit the use of CFC stage by stage, China classifies the refrigeration plant that contains CFC-11 and CFC-12 as the nonimportation material.Technological difficulties maximum during waste refrigerators is handled are exactly the control of CFC.So generally, can extract it earlier for the processing of waste refrigerators, carry out fragmentation again, in order to avoid loosing in shattering process, it overflows in air.Yet its extraction yield is the highest also can only to reach 95%, and increases operating procedure, therefore, needs this technology is improved.

The utility model content

The technical problem that solves: the utility model provides a kind of waste refrigerators disintegrating machine with the PLC programmable function, can discern the heat-insulating material in the heat insulation layer, to containing the thermal insulation layer of blowing agent, to reclaim cold-producing medium and be transported to steel cylinder in liquid mode and store the separation of harmful substances such as solution waste refrigerators CFC.

Technical scheme: a kind of waste refrigerators disintegrating machine, comprise disintegrating machine, its special character is: described disintegrating machine is provided with Programmable Logic Controller PLC and hydrocarbon monitoring alarm device.

In described disintegrating machine bottom the refrigerant-recovery carrier pipe being installed is connected with liquid storage cylinder fitted.

Beneficial effect: for the whole fragmentation of refrigerator, blowing agent contained in the heat insulation layer will cause very big influence to fragmentation.If directly broken, then blowing agent looses easily to overflow and escapes to overflow in air in air or by exhaust treatment system again, and ozone layer is damaged.The utility model can be implemented in the whole shattering process, the synchronous fragmentation of thermal insulation layer, its Programmable Logic Controller PLC stored program controlled can be discerned the heat-insulating material in the heat insulation layer, to containing the thermal insulation layer of blowing agent, to reclaim cold-producing medium and be transported to steel cylinder in liquid mode and store, solve the separation of harmful substances such as waste refrigerators CFC, easy to operate.Be equipped with hydrocarbon monitoring alarm device, realize safety in production.
