Equipment for continuously preparing isocyanate

Abstract

The invention discloses equipment for continuously preparing isocyanate. The equipment comprises a base plate, a side plate and a top plate, the side plate is fixedly installed on the upper surface ofthe base plate, the top plate is fixedly installed on the upper surface of the side plate, a reaction barrel is rotatably installed on the upper surface of the base plate, a rotating device is fixedly installed at the position, corresponding to the reaction barrel, of the upper surface of the base plate, a material conveying pipe is inserted into the top end of the reaction barrel, the material conveying pipe is inserted into the top plate, a meter is fixedly installed on the inner wall of the material conveying pipe, and an electromagnetic valve is fixedly installed at the end, located on the meter, of the outer wall of the material conveying pipe. According to the equipment for continuously preparing isocyanate, a diamine hydrochloride solution is conveyed into the reaction barrel through the meter and the electromagnetic valve on the outer wall of the conveying pipe, the reaction barrel is driven by the rotating device to rotate, and the diamine hydrochloride solution in the reaction barrel is comprehensively illuminated in cooperation with an illumination mechanism, so that the isocyanate preparation efficiency is conveniently improved, the use by a user is convenient, and theuse efficiency of the user is improved.

Description

technical field [0001] The invention relates to the technical field of soft brine, in particular to a device for continuously preparing isocyanate. Background technique [0002] Rubber is a polymer material with high elasticity, strong wear resistance, high friction coefficient and excellent adhesion, which is widely used in modern human society; but in most cases rubber products need to use skeleton materials such as fibers and steel wires To improve the strength and dimensional stability of the rubber material; and in order to improve the bonding strength between the skeleton material and the rubber, it is often necessary to treat the skeleton material with surface dipping, wherein the water-based dipping material is the surface dipping of the skeleton material It is an important raw material in the process of processing, and blocked isocyanate is currently a commonly used water-based dipping material. [0003] In the preparation process of the existing isocyanate, the di...

Problems solved by technology

[0003] In the preparation process of the existing isocyanate, it is necessary to transport the diamine hydrochloride solution into the reactor, react with phosgene under normal pressure or pressurized conditions, and perform light reaction to obtain a high-concentration isocyanate photochemical solution. Most of the light reactors fix the position of the light source, which is not convenient to fully illuminate the diamine hydrochloride solution in the reactor, resulting in poor quality of isocyanate, and it is not convenient for continuous preparation of isocyanate, and the safety and reliability are not high. The convenience of installation and the stability of the current structure need to be improved. For this reason, we propose a continuous preparation of isocyanate equipment
