Rotary seal valve for production of liquid crystal polyester

Abstract

The invention provides a rotary seal valve for production of liquid crystal polyester. The rotary seal valve for the production of the liquid crystal polyester comprises a trolley, wherein a machine frame is installed on the trolley, a valve body is installed on the machine frame, a rotor is installed in the valve body, a material receiving groove is formed in the rotor through a group of dummy plates, a feeding port is formed in the upper portion of the valve body, a discharging port is formed in the lower portion of the valve body, a feeding channel which communicates with the interior of the valve body is formed in the feeding port, a screen plate obliquely arranged is installed in the feeding channel, one side of the screen plate is connected with the inner wall of the feeing channel through a rotation shaft, the other side of the screen plate is connected with the inner wall of the feeding channel through a pull spring, a shock excitation hammer is arranged on a part, located on one side of the pull spring, of the screen plate, and a transparent seal door is arranged on a position, corresponding to the bottom of the screen plate, in the feeding channel where the screen plate is installed. Jamming of the rotary seal valve for the production of the liquid crystal polyester can be effectively prevented in the work process, and therefore smooth proceeding of the production isguaranteed, and potential safety hazard of workers is eliminated.

Description

Technical field: [0001] The invention relates to a rotary sealing valve for liquid crystal polyester production, which belongs to the technical field of valves. Background technique: [0002] The main varieties of liquid crystal polyester are polyacrylate (aryl) ester, polymethacrylate (aryl) ester, polyparaben, aromatic polyester (homopolymer or copolymer) and so on. It has the characteristics of high strength, good thermal stability and chemical stability. It is prepared by polycondensation of dibasic acid or diacyl chloride with dibasic phenol or dibasic alcohol. Mainly used in electronics, electrical appliances, automobiles, machinery, aviation, aerospace and chemical industries. [0003] In the production process of liquid crystal polyester, the valve, as an indispensable production equipment, plays a vital role in the production process.

AI Technical Summary

Problems solved by technology

[0003] In the production process of liquid crystal polyester, the valve, as an indispensable production equipment, plays a vital role in the production process. The structure of the conventional rotary sealing valve is driven by the reducer. The rotor of the rotary sealing valve is in accordance with the regulations. Rotate in the direction of rotation, the receiving trough formed by the rotor blades receives coke at the inlet of the rotary sealing valve and rotates counterclockwise to the outlet of the rotary sealing valve to discharge the material. The feed port will not form a through state. Due to the high viscosity of liquid crystal polyester, jamming is easy to occur, and most of the raw materials for production are toxic substances. It is quite dangerous to deal with the jamming of rotary sealing valves.
