Description
Technical field
The utility model belongs to battery crushing and reclaimer, particularly a kind of fragmentation of dry cell and retracting device.
Background technology
The world demand amount of dry cell continues steady-state growth in various countries, China's dry cell output occupies first place in the world, and except that part outlet, sells at home and accounts for major part.Just throw away behind the used for dry cell, the one, cause the soil severe contamination, No. 1 battery of 1 joint rots and can make 1 square metre of soil compaction in soil according to surveying and determination, and urase, hydrogen chloride enzyme, invertase activity in the soil are descended, and makes soil forever lose use value; The 2nd, biological pollution, can pass through plant at toxic metals such as mercury in soils, cadmium, lead---food chain enters human body, and influence is physically and mentally healthy; The 3rd, cause water pollution, a button cell can make 600t water be polluted; The 4th, cause air pollution, used dry batteries enters rubbish, causes volatilization, the atmosphere pollution of mercury, lead, cadmium, ammonium chloride, contaminated environment with the waste incineration meeting; The 5th, dry cell contains a large amount of precious metals, contains materials such as multiple metal such as mercury, cadmium, lead, nickel, zinc, manganese, copper and iron and ammonium chloride, graphite in the dry cell, and if can rationally utilize is valuable metals resources.At present both at home and abroad the dry cell recovery technology has machinery (artificial separation) facture, dry method, wet method, little think of a way or the like, or the method for several method combination, external dry cell pulverizer has the gyratory crusher of Sweden AB (SR) company, it has a rotation crushing ring, relies on this ring dry cell to be sheared and fragmentation; Also have Japanese NEC Corporation and Germany all to adopt and earlier dry cell is cut into several sections, several sections shells and the material that will shear with pulverizing mill then are ground into tiny fragment, belong to two-stage shearing and broken pattern.Domestic dry cell disintegrating machine and processing unit are at the early-stage, mostly copy the two-stage of Japan and Germany and shear and the pulverization process pattern.The material of shell of aneroid battery is the fine crystallization sheet metal, be applicable to cold stamping, the deep drawn steel, yield strength height, pressure are between 335MPA～690MPA, exceed one times to three times than general steel, have good toughness and plasticity, shell of aneroid battery stretches with the band steel and forms, and thickness is reduced to 0.2mm from the 0.25～0.3mm in past, what have also reduces to 0.15～0.18mm, also has the trend that further reduces.The pulverizer that uses both at home and abroad goes wrong a lot of at present, mainly be: easily the dry cell material is clamped in the housing of being cut off with the method for shearing, be difficult to be scattered, then pulverize with pulverizer, material is meticulous, this method is a conventional art, need to shear and pulverize bi-level treatment, cost of equipment is increased, energy consumption increases, main cause more than conventional method goes wrong is not catch the dry cell characteristics, the firstth, and shell thin (0.15～0.18mm); The secondth, yield strength high tenacity and plasticity are good; The 3rd is that the housing of dry cell shell after deep drawn is near maximum yield strength.The dry cell disintegrating machine is for first type at first the dry cell shell to be cut into more piece both at home and abroad, and then crushing shell and material, is crushed to 0.1-0.3mm, and dry cell forms to be sheared and broken two-stage process; Second type is to rely on the gap between rotation crushing ring and the equipment to carry out the broken dry cell of shear action and decompose dry cell.
