AI Technical Summary

Technical Problem

In the prior art, during the preparation of carboxybutyronitrile latex, raw materials may be adhered to the inner wall of the reactor, resulting in the temperature control device being unable to effectively control the temperature and affecting the reaction efficiency.

Method used

An anti-attachment device including a curved plate, an elastic telescopic rod and a short rod is designed to scrape away the raw materials of the adhesive through the reciprocating movement of the arc plate, and the free end of the elastic telescopic rod is contracted to remove the arc plate from the inner wall of the reactor, preventing long-term scraping from damaging the service life of the reactor.

Benefits of technology

Effectively prevent raw materials from sticking to the inner wall of the reactor, ensure that the temperature control device can effectively control the temperature, improve reaction efficiency, and extend the service life of the reactor.

Abstract

The invention discloses a preparation device and a preparation process of high-performance carboxyl nitrile latex, and relates to the technical field of carboxyl nitrile latex preparation, comprising: a reactor, wherein a feed pipe is fixedly installed on the top of the reactor, a motor is fixedly installed on the top of the reactor, a discharge pipe is fixedly installed on the bottom of the reactor, and a spiral heating tube is arranged inside the reactor; an anti-adhesion device, wherein the anti-adhesion device comprises a reciprocating screw, a threaded block, a fixed rod, an elastic telescopic rod, an arc plate, a connecting frame, a short rod, a rotating plate, a limiting block, a convex block and a groove, wherein the reciprocating screw is driven to rotate by the rotation of the motor, the rotation of the reciprocating screw drives the threaded block to reciprocate up and down, the up and down reciprocating motion of the threaded block drives the elastic telescopic rod to reciprocate up and down, and the up and down reciprocating motion of the elastic telescopic rod drives the arc plate to move up and down, so as to prevent the raw materials from adhering to the inner wall of the reactor to form a thick layer, thereby affecting the heating effect of the spiral heating tube on the carboxyl nitrile latex inside the reactor.
