ABS plastic recycling and cleaning re-production production line

Abstract

The invention relates to an ABS plastic recycling and cleaning re-production production line. The ABS plastic recycling and cleaning re-production production line comprises a feeding machine, a magnetic separation device, a first cleaning tank, a first dehydration and transfer mechanism, a spraying mechanism, a first conveying mechanism, a second cleaning tank, a second dehydration and transfer mechanism, a drying mechanism, a first plastic cap separation device, a second plastic cap separation device, a second conveying mechanism and a color sorting device from left to right. According to theproduction line, by arranging the first dehydration and transfer mechanism, the spraying mechanism and the first conveying mechanism between the first cleaning tank and the second cleaning tank, cleaning liquid carried with materials from the first cleaning tank is thoroughly removed from the materials which are cleaned for the first time through the first dehydration and transfer mechanism, thenremaining chemicals on the surfaces of the materials are removed through the spraying mechanism, afterwards, the materials are transported into the second cleaning tank through the first conveying mechanism, and the situation that the chemicals on the surfaces of the materials which are cleaned for the first time contaminate the second cleaning tank, and the cleaning and separating effect at thesecond time is influenced accordingly is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of waste plastic recycling and reprocessing, in particular to an ABS plastic recycling, cleaning and reproducing production line. Background technique [0002] In daily life, there are many waste plastics, such as plastic bags, buckets, basins, toys, furniture, stationery and other living utensils and various plastic products, buttons and zippers in the clothing industry, various building components and building tools in building materials. , plastic doors and windows, plaster buckets, etc., agricultural film, pumping pipes, agricultural machinery, fertilizer packaging bags, cement packaging bags, etc., various forms of bearings, gears, cams, different wheels, sealing rings, etc. in the mechanical field Various blades, various water pump impellers, reactors, pipes, containers, pumps, valves, etc. in the chemical field will produce waste plastics. Due to the non-degradability of plastics, these waste plastic...

Problems solved by technology

[0004] In the above cleaning process, magnetic separation is the most basic and important step, because the recycled waste plastics will inevitably be mixed with magnetic metal pieces such as iron, cobalt, nickel, etc. If these metal pieces are not separated from the material, then Not only will it affect the quality of recycled plastics, but it will also damage the mechanical equipment in the subsequent production process

A magnetic separator whose Chinese patent publication number is CN108972955A includes a frame, a magnet and a motor. The two ends of the frame are respectively provided with a driving roller and a driven roller, and a conveyor belt is connected between the driving roller and the driven roller. , the motor is connected to the driving roller, and the magnet is fixedly arranged in the middle of the frame. Although this design can separate the plastic block and the metal block to a certain extent, since the magnetic separator is separately installed at the entrance of the material conveyor belt, only the magnet Attract the metal blocks in the inlet section to separate the metal blocks from the plastic blocks. When the feeder feeds the conveyor belt, various materials will be stacked together. This magnetic separation method can only absorb lighter metal blocks. And the metal block on the surface, the metal block pressed by the plastic block is difficult to be absorbed, so the separation of the metal block is not thorough enough, and the chute of this kind of magnetic separator is set at both ends, and it must be recovered at both ends The metal block increases the workload. In addition, this separately set magnetic separator also increases the production cost

[0006] The existing dehydration mechanism uses a conventional screw to lift the material and remove the water, but when the material is lifted, the material accumulates on the helical blade, and the cleaning liquid located on the inner side of the helical blade close to the screw shaft is not easy to flow out, and the cleaning solution located on the inside of the helical blade is not easy to flow out. The cleaning liquid on the surface of the material outside the screw blade will partly scatter on the material of the blade below as it rotates, thus causing poor dehydration effect, and the part that slides down with the inner wall of the screw pipe will continue to accumulate at the bottom during continuous production, and finally Into the screw pipe, causing the screw to lose the dehydration function when lifting the material; in addition, after the existing dehydration mechanism dehydrates the material after the first cleaning, there will still be a certain amount of chemical residue on the surface of the material when it enters the second cleaning. In the later stage of continuous production, it will still cause pollution to the second cleaning tank, thus affecting the effect of the second cleaning and separation

[0007] The invention of Chinese Patent Publication No. CN 108332546 A provides a material dehydrator, which includes a frame, a drainage assembly, a feeding cylinder, a feeding motor, a lifting cylinder, a feeding screw, a feeding hopper, a lifting screw, a discharging hopper, a main Although the design of the drainage component of the motor solves the problem of water accumulation at the bottom of the lifting screw, the design of the lifting screw cannot achieve a good dehydration effect, and it cannot solve the influence of residual chemicals on the surface of the material
