Description

Masterbatch removes piece device

Technical Field

The invention relates to the technical field of masterbatch processing, in particular to a masterbatch screening device.

Background

The color master batch is prepared by mixing and plasticizing granulation raw materials by an extruder to form a plastic melt after stirring a colorant (pigment or dye), a carrier, a dispersant and other auxiliary components at a high speed, extruding plastic strips by using an extruder die head, and cooling, granulating, drying and blending the plastic strips to obtain the standard color master batch. Many chips are easily produced in the process of actually producing color master batches, for example, the temperature of the granules is too high during the granulation, and the granules are produced into chips in the granulation process due to different angles and sharpness of blades of a granulator. In the masterbatch production process, the continuous accumulation of piece can block up the filter core in the vacuum hopper that links to each other with empty pipeline, causes the pumping ability to descend, and reinforced not smooth and easy, regularly clears up the filter core, influences the production productivity. In addition, small scraps are adsorbed at the dead angle of the equipment, and cracking is easily generated in the continuous high-temperature operation process of the equipment, so that crystal points are formed, and the quality of products is influenced. Therefore, the generated scraps need to be removed in time after the plastic strips are granulated. Chinese application patent CN201020189338.3 discloses a filler masterbatch pellet winnowing machine, which screens out pure filler masterbatch without other impurities such as dust and the like by the principle of winnowing.

Chinese application patent CN201920871509.1 discloses a food grade color master batch vibration dusting device, which utilizes the principle of vibrating screen, the acting force of the granule and granule fluidization plate is large, the vibration granule is loose, which is helpful for the separation of dust on the surface of granule, the baffle raised line on the granule fluidization plate retards the granule, and the dusting effect is improved. The equipment disclosed in the prior patent cannot separate and recover the cut grain fragments simultaneously, or the separation and recovery efficiency is not high, so that the equipment is not beneficial to large-scale production operation. In addition, static electricity exists in conveying friction among the plastic color master batches, the single washing, air washing and vibration washing effects are poor, and fine dust is not easy to remove.

The feed inlet of the chip separation device 4 is connected with a baffle 15, and concave runners are uniformly distributed on the surface of the baffle and used for uniformly dispersing the color master batches onto the guide plate. The guide plate has 4 layers, and the two ends of the guide plate are a right-angled trapezoid blocking plate 25 and a right-angled trapezoid blocking plate 27. A stainless steel wire mesh plate 26 with the aperture ratio smaller than that of the color master batch is fixed between the barrier plates, and the wire mesh plate and the right-angle edges of the two barrier plates form an acute angle, so that the color master batch can slide down on the guide plate under the action of gravity. The separation plate mainly plays a fixed role, and on one hand, the stainless steel wire mesh plate is fixed, and on the other hand, the guide plate is fixed on the inner wall of the debris separation device 4. The bottom of the chip separating device 4 is a masterbatch outlet 6, and the masterbatch outlet and the masterbatch inlet are positioned on the same side. The middle part of the debris separating device 4 is provided with an induced draft opening 16, and the induced draft opening 16 is connected with the heater 11 and the blower 12 through pipelines.
