Description

Technical Field

[0001] The present invention relates to the technical field of screening of chlorinated polyethylene particles, and particularly to a screening device for anti-caking chlorinated polyethylene particles. Background Art

[0002] Chlorinated polyethylene is a modified polymer prepared by the substitution reaction of polyethylene with chlorine. With the substitution of chlorine, the crystallinity of polyethylene is destroyed, and the glass transition temperature is reduced. However, after exceeding a certain chlorine content, the glass transition temperature increases again. Chlorinated polyethylene has two typical structures. One is that chlorine atoms are randomly and evenly distributed on the macromolecular chain, becoming a saturated elastomer. The other is that chlorine atoms are randomly and unevenly block-distributed on the macromolecular chain, showing the behavior of hard plastics. Chlorinated polyethylene with a chlorine content of 25%-45% is a special rubber with heat resistance, weather resistance and flame retardancy. Chlorinated polyethylene with a chlorine content exceeding 45% is a white, uniform, granular amorphous solid.

One side of the net body 542 away from the fixed wall 541 is fixedly connected to the surface of the base 551.

[0030] During use, chlorinated polyethylene particles are quantitatively conveyed to the surface of the net body 542. The bottom of the fixed wall 541 is fixedly connected to the output end of the hydraulic cylinder 53.

The extending direction of the material dropping shell 564 is tangent to the surface of the assembly wall 561.

[0032] During use, the mesh body 542 is arranged at the upper position on the inner side of the fixed wall 541. The distance between the top of the fixed wall 541 and the mesh body 542 is the laying layer thickness of the chlorinated polyethylene particles. The chlorinated polyethylene particles are laid flat on the surface of the mesh body 542. The electric cord 544 transmits the vibration of the vibrator to the rubber strip 543. The vibration of the rubber strip 543 causes the mesh body 542 to vibrate.

[0034] During use, the inner side of the fixed wall 541 supports the mesh body 542. The chlorinated polyethylene particles are conveyed in portions to the surface of the mesh body 542. The vibration of the rubber strip 543 promotes the particles to be laid flat on the surface of the mesh body 542. The small-diameter particles fall into the interior of the fixed wall 541. The electric cylinder 661 is moved to the upper position above the color-difference particles. The electric cylinder 661 drives the bent pipe 662 to move downward. The input end of the air pump 665 is communicated with the interior of the collection tank 664. The flow of the gas causes the color-difference particles to enter the bent pipe 662 through the straight pipe end 663. The color-difference particles enter the collection tank 664 with the airflow for collection. The electric cylinder 661 resets to realize the collection and removal of the color-difference particles.
