Description

Mixing crusher

Technical field:

The present invention relates to a kind of disintegrating apparatus, be specifically related to a kind of mixing crusher of waste refrigerator break process.

Background technology:

Relevant statistics shows, the social recoverable amount of China's refrigerator is about 1.3 hundred million, on average scrap every year more than 4,000,000, the refrigerator of scrapping contains environmentally harmful materials such as freon, need obtain appropriate processing disposes, contain again in the waste refrigerators simultaneously in a large number and can have higher recycling and be worth for metal, glass and the plastics etc. recycled.If can effectively handle and recycle the waste refrigerators that increases day by day, the pressure for alleviating the china natural resources shortage alleviates environmental pollution, sets up recycling economy society and all have positive effect and important meaning.

At present, because the research of China aspect the waste refrigerators recycling is ripe not enough, do not form the recovery system and the ripe treatment process of science, a large amount of waste refrigerators is mainly handled by two channels: the one, flowed into low-income household or rural area again after the simple process renovation, and there is the hidden danger of environmental pollution; The 2nd, in the individual workship that does not satisfy the requirements, disassembled by manual, after reclaiming useful resources, remaining a large amount of poisonous and harmful substance not only causes the huge wasting of resources, more the environment of severe contamination locality by toppling over, bury or mode such as burning being discharged in the middle of river, ground and the atmosphere.

Summary of the invention:

Technical problem to be solved by this invention is: at the problem of above-mentioned prior art existence; and provide a kind of the collection to tear up and broken dual mode, realize material coarse crushing and in small, broken bits, floor space is little, save belt conveyer and repeat feed arrangement, small investment, reduction dust emission, be easy to shattering process is carried out the mixing crusher that the waste refrigerator of dedusting anti-explosion safety protection is handled.

The technical solution used in the present invention is: the motor that connects successively is installed in gantry base, driving belt and rotating shaft, the discharging chamber is installed on the gantry base, crusher chamber and tear up the chamber, the crusher chamber wall is equipped with stationary knife, be fixedly connected with cutter supporter on the rotating shaft in the crusher chamber, be mounted with cutting knife on the cutter supporter, also be fixedly connected with roller bracket on the rotating shaft, by bearing pin rotating band discaling roll wheel is installed on the roller bracket, the discharging chamber is positioned at the crusher chamber below and connects with crusher chamber, discharging is equipped with material scraping plate in the chamber, material scraping plate is fastened on the rotating shaft, crusher chamber top is connected and installed tears up the chamber, tear up the powerful rotating shaft of 2 wide-angle hexagon prisms that driven respectively by 2 heavy-duty motors is installed in the chamber, be mounted with on the powerful rotating shaft and tear up cutter, tear up the top, chamber and be connected and installed feed cavity, the feed cavity top connects the outlet of negative pressure ventilation and dust removal dust.

In the technique scheme, feed cavity one side is connected and installed the elevating hopper device, and the feed cavity opposite side is connected and installed material pressing device.

Operation principle:

The material of various different components is after belt conveyor is delivered to crusher chamber 1, at first tear up the rectangular bulk that cutter (rotation in opposite directions) is shredded into material 400～600mm (length) X40mm (wide) X40mm (height) by what the powerful rotating shaft of wide-angle hexagon prism drove, material after tearing up falls into crusher chamber 2, then under the impact of rotating running roller, shearing, extruding, bending, the material of variant component separates fully, and the material after the separation is delivered to discharging opening by material scraping plate.In whole shattering process, adopt negative pressure to collect dust and all kinds of harmful or explosion hazard gases, and adopt nitrogen that the broken overall process of two-stage, course of conveying and dedusting are protected, control oxygen content (volumetric concentration) is lower than 8%.

This machine integrates two kinds of crumbling methods, can realize the coarse crushing of material and two kinds of separation in small, broken bits, and it is little to have floor space, small investment, reduces dust emission and is easy to shattering process carried out advantages such as dedusting and explosive-proof protector.

Twin shaft tears up the motion principle and the advantage of crumbling method (the 1st grade of fragmentation): drive the powerful rotating shaft of 2 wide-angle hexagon prisms respectively by 2 motors and rotate in opposite directions, the cutter that tears up that be installed on the rotating shaft this moment carries out baiting of high pulling torque to material, thereby material is torn up.The broken mode in this road has characteristics such as moment of torsion is big, low energy consumption, low noise, low dust, is particularly suitable for the broken apart of the thick material of especially big spy.

The motion principle of rotation running roller crumbling method (the 2nd grade of fragmentation): rotate by belt pulley driven rotary axle 2 by motor 1, the cutting knife that is installed on the cutter supporter on the rotating shaft 2 is sheared material earlier with the stationary knife that is installed on the crusher chamber wall, material continues descendingly then, and being installed between rotation running roller (band tooth) on the roller bracket and the bearing pin has very big free gap.When roller bracket revolves round the sun with rotating shaft 2, rotation running roller (band tooth) is on the one hand around rotating shaft 2 rotations, on the one hand not only under action of centrifugal force but also around the bearing pin rotation, rotate running roller (band tooth) this moment and be installed in gap between the stationary knife on the crusher chamber wall little when big then the time, material then is subjected to rotating impact, shearing, extruding, the bending between running roller (band tooth) and the stationary knife during by this gap, the material of various unlike materials separates and volume is real respectively, and the material after will being separated by material scraping plate then draws off.The dust that the while material produces in shattering process is collected by dust pelletizing system.
