Description
Technical Field
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
In daily life, many waste plastics, such as plastic bags, barrels, basins, toys, furniture, stationery and other living appliances and various plastic products, buttons and zippers in the clothing industry, various building components, building tools, plastic doors and windows, mortar barrels and the like in building materials, agricultural films, water pumping pipes, agricultural implements, fertilizer packaging bags, cement packaging bags and the like in agriculture, various types of bearings, gears, cams, different wheels, sealing rings, various blades, various water pump impellers in the mechanical field, reaction kettles, pipelines, containers, pumps, valves and the like in the chemical field can generate the waste plastics. Because of the nondegradable property of plastics, the waste plastics can seriously pollute the ecological environment if being treated improperly. Among the methods for treating waste plastics, recycling waste plastics is the most effective and feasible way to save resources.
The waste plastic recycling and regenerating process comprises classification pretreatment, crushing, cleaning and granulation, wherein the cleaning process generally comprises feeding, magnetic separation, cleaning, dehydration, rubber-plastic separation and color separation. The crushed materials are conveyed to a magnetic separation device through a feeding machine, metal blocks in the materials are separated out, then the materials enter a first cleaning pool for first cleaning, plastic blocks of various materials, such as PP, PVC, PE, PET, PS, PU and the like, are contained in the materials besides ABS plastic blocks, the densities of the plastics are different, the crushed volumes are different, so that the plastic blocks of different materials have different weights, accordingly, the densities of pool water can be adjusted by adding proper agents into the first cleaning pool, so that the plastic blocks of different materials are separated while the materials are cleaned, then the plastic blocks enter a second cleaning pool for water cleaning to remove solvents on the surfaces of the plastic blocks, meanwhile, the materials with lighter specific gravity in the plastic blocks are separated again, the ABS plastic blocks are collected, and rubber caps also exist in the plastic blocks, so that the plastic blocks are separated out through a rubber and plastic separation device after being dehydrated and dried, and feeding the residual ABS plastic blocks into a color selection device for color separation.
In the above cleaning process, magnetic separation is the most basic and important step, because magnetic metal blocks such as iron, cobalt, nickel and the like are inevitably mixed in the recovered waste plastics, if the metal blocks are not separated from the materials, the quality of the recycled plastics is influenced, and mechanical equipment in the subsequent production process is damaged. The magnetic separator with the Chinese patent publication No. CN108972955A comprises a frame, a magnet and a motor, wherein a driving roller and a driven roller are respectively arranged at two ends of the frame, a conveying belt is connected between the driving roller and the driven roller, the motor is connected with the driving roller, and the magnet is fixedly arranged at the middle part of the frame, although the design can separate plastic blocks and metal blocks to a certain extent, the magnetic separator is independently arranged at the inlet of a material conveying belt, the metal blocks and the plastic blocks are separated only by attracting the metal blocks in the inlet section by the magnet, when the feeding machine feeds the conveying belt, various materials can be stacked together, the magnetic separation mode can only adsorb the light metal blocks and the metal blocks on the surface, the metal blocks pressed by the plastic blocks at the bottom are difficult to adsorb, therefore, the separation of the metal blocks is not thorough, and the chutes of the magnetic separator are arranged at two ends, the need to recover the metal lumps at both ends increases the amount of work and, in addition, the separately arranged magnetic separator also increases the production costs.
Dehydration is also an important part of the overall cleaning process, and needs to be more thoroughly dehydrated after both the first and second cleaning. The first cleaning is performed by adding a medicament into the first cleaning tank, the second cleaning is performed by cleaning and separating with clear water, and in order to prevent the medicament brought by the material into the second cleaning tank from polluting the water in the second cleaning tank and affecting the second cleaning and separating effect, a dewatering mechanism is arranged between the first cleaning tank and the second cleaning tank to thoroughly remove the medicament brought by the material; and the material after the second washing separation can be sent to stoving mechanism and carry out drying process, in order to alleviate follow-up stoving burden, improves drying efficiency, also needs to carry out dehydration before sending into stoving structure.
The existing dehydration mechanism adopts a conventional screw to lift materials and remove water, but when the materials are lifted, the materials are accumulated on a spiral blade, cleaning liquid at the inner side of the spiral blade, which is close to a screw rotating shaft, is not easy to flow out, and the cleaning liquid on the surface of the materials at the outer side of the spiral blade is partially scattered on the materials of the blades below along with the rotation, so that the dehydration effect is poor, and the part sliding along with the inner wall of a screw pipeline is continuously accumulated at the bottom in continuous production and finally enters the screw pipeline, so that the screw loses the dehydration function when the materials are lifted; in addition, after the materials after the first cleaning are dehydrated, certain agents still remain on the surfaces of the materials when the materials enter the second cleaning by the conventional dehydration mechanism, and the second cleaning pool is still polluted in the later stage of continuous production, so that the effect of the second cleaning and separation is influenced.
The invention discloses a material dehydrator under the patent of CN 108332546A, which comprises a frame, a drainage component, a feeding cylinder, a feeding motor, a lifting cylinder, a feeding screw, a feeding hopper, a lifting screw, a discharging hopper and a main motor.
Therefore, there is a need to improve the existing ABS plastic recycling cleaning reproduction line to solve the above problems.

Such design makes the material on the one hand can pass through some washing liquids of waterlogging caused by excessive rainfall gap driping in-process promoting, and on the other hand makes the material when promoting the comparatively narrow department in upper portion on some material be obstructed and drop to the great first helical blade 472 of diameter below to the time of material promotion conveying has been prolonged, so that the washing liquid on material surface is driped as far as.
Further, the second spiral blade 473 corresponds to the feeding end of the discharging pipe 43, so that the material on the second spiral blade 473 can smoothly enter the discharging pipe 43.
Because in continuous production, the washing liquid can get into feed channel 41 along with the material is continuous, if the washing liquid that drops off also along with the inner wall landing of screw pipeline 42 to the bottom of feed channel 41 in the material lifting process, then when the washing liquid is more and more, can get into in the screw pipeline 42 to make the effect that the lift screw can no longer play and drop off material surface washing liquid. For this reason, the present invention provides a filter plate 45 at the lower side of the screw pipe 42 near the bottom, and a water receiving tank 46 at a position corresponding to the filter plate 45 directly below the screw pipe 42, so as to receive the cleaning liquid falling from the filter plate 45, which is the second difference of the first dewatering conveyor 4 of the present invention compared to the prior art.
