Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, and particularly to a solid-liquid separation device for chlorinated polyethylene. Background Technique

[0002] Chlorinated polyethylene has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and has good oil resistance, flame retardancy and coloring properties, so it is widely used in industries such as wire and cable, and automotive parts manufacturing. In the production process of chlorinated polyethylene, centrifugal equipment is needed to separate liquid and solid particles.

[0003] After retrieval, the utility model patent with the publication number of CN217450550U discloses a centrifugal device for chlorinated polyethylene production, including an inner cylinder, an outer cylinder and a cover body. The bottom of the inner cavity of the inner cylinder is fixedly connected with a coaxially arranged mounting cylinder seat. The mounting cylinder seat is a hollow structure, and a hollow main shaft passes through the inside of the mounting cylinder seat. The hollow main shaft is a hollow structure and is communicated with the inner cavity of the inner cylinder. A main bearing seat is assembled on the hollow main shaft, and the main bearing seat is fixedly connected to the bottom of the outer cylinder; a first hydraulic cylinder arranged upside down is installed at the center of the cover body, and the end of the piston rod of the first hydraulic cylinder is fixedly connected with two symmetrically arranged arm rods, and a hard brush is installed at the lower end of the arm rod; this centrifugal device for chlorinated polyethylene production can achieve self-cleaning during the solid-liquid separation process, ensure the lasting stability of solid-liquid separation, and can improve the integration degree of the equipment.
