Abstract
The invention discloses a recovery processing method for a waste refrigerator. After components of the waste refrigerator are disassembled from the waste refrigerator, secondary crushing and dedusting are conducted on the components, waste iron, waste copper and aluminum and polyurethane are separated and selected from the components, then manual sorting is conducted, and waste plastic with purity of 95% is obtained. The size of the processed waste refrigerator is 1/10 of that of the original waste refrigerator, and the purpose of waste reduction is achieved. Different kinds of metal and plastic can be separated and selected from crushed objects and can be reused, and the recycling purpose is achieved. The number of sorting workers is small, the sorting efficiency is high, and operating cost is low; the selected materials are high in purity, and the purity can be above 95%.
Description
Technical field
The invention belongs to urban life family expenses waste refrigerators process field, relate to a kind of for all kinds of waste refrigerators that city is collected carry out fragmentation, sort, dedusting, classification recycling, reach recycling of resource, the recovery and treatment method of the waste refrigerators of waste electrical equipment minimizing, resource and harmless treatment target.
Background technology
Along with the fast development of China's economy, the household electrical appliance output of China increases day by day, and the processing of household electrical appliance has become with disposal the serious problems that China big and medium-sized cities must face solution; At present in the household electrical appliance of China, the annual production of refrigerator, approximately to 4145.41 ten thousand, and is also increasing year by year; How to realize that the urban life household electrical appliance are innoxious, " three change " of minimizing and resource process the focus that has become research.
After the general employing of waste refrigerators recycling at present is broken, the mode of artificial separation is carried out, sub-elect waste plastics, scrap iron, copper scrap and aluminium scrap in waste refrigerators, the efficiency of separation is low, and cost is higher, simultaneously, sorting the working environment of workers is severe, and dust, foul smell cause great injury to operating personnel's physical and mental health.
Summary of the invention
Purpose of the present invention, provide the recovery and treatment method of the waste refrigerators that a kind of efficiency of separation is high exactly in order to address the above problem.
The object of the present invention is achieved like this:
The recovery and treatment method of a kind of waste refrigerators of the present invention comprises the following steps:
S1: disassembling discarded refrigerator is become to the waste refrigerators parts, then the waste refrigerators component feed is carried out to primary fragmentation to preliminary crusher, be crushed to the following particle size of 200mm, then be delivered to recursher and carry out second-time breakage, be crushed to the following particle diameter of 30mm;
S2: will send into successively in magnetic separator through the waste refrigerators particle of second-time breakage and select scrap iron, and send in non-iron grading machine and select copper scrap and aluminium scrap, send in winnowing machine and select polyurethane;
S3: the surplus materials after the winnowing machine selection by winnowing is transported on the artificial separation machine and carries out artificial separation, the material after artificial separation is collected to recycling.
The recovery and treatment method of above-mentioned a kind of waste refrigerators, wherein, collect by pipeline the dust produced in step S1 shattering process, then by the precipitron centralized recovery, processes.
The recovery and treatment method of above-mentioned a kind of waste refrigerators wherein, is separated airborne freon when collecting dust, then preserves and processes.
The recovery and treatment method of above-mentioned a kind of waste refrigerators, wherein, in step S1, preliminary crusher is selected double-shaft crusher, and recursher is selected hammer mill.
The volume that the present invention processes rear discarded object is original 1/10, has solved the problem of minimizing; Sub-elect various metal, plastics from broken thing, can effectively utilize once again, solved the problem of resource; The sorting workman is few, and the efficiency of separation is high, and operating cost is low; The feed purity of selecting is high, can reach more than 95%.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
The invention discloses a kind of recovery and treatment method of waste refrigerators, comprise the following steps:
S1: waste refrigerators is transported into through transport vehicle, simply disassemble into the waste refrigerators parts, then the waste refrigerators component feed is carried out to primary fragmentation to preliminary crusher (double-shaft crusher), be crushed to the following particle size of 200mm, be delivered to again recursher (hammer mill) and carry out second-time breakage, be crushed to the following particle diameter of 30mm; The dust produced in shattering process is collected by pipeline, then process by the precipitron centralized recovery; When collecting dust, airborne freon is separated, then properly preserved and process;
S2: will first send in magnetic separator and select scrap iron through the waste refrigerators particle of second-time breakage, surplus materials is sent in non-iron grading machine and selected copper scrap and aluminium scrap again, finally the surplus materials after the sorting of non-iron grading machine is sent in winnowing machine and carried out selection by winnowing, select polyurethane; Scrap iron, copper scrap and aluminium scrap and the polyurethane sub-elected is carried out respectively to recycling;
S3: the surplus materials after the winnowing machine selection by winnowing is transported on the artificial separation machine and carries out artificial separation, sort out useless impurity, as black plastics, stone, earth, waste paper etc., make plastics in the surplus materials after artificial separation account for more than 95%, the material after artificial separation is collected to recycling.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
