Nozzle for high-shear homogenate pump

Abstract

The invention relates to a spraying device which is matched with a high-shear homogenate pump and is suitable for polymerization hydrolysis processes in the petrochemical acrylic industry. The nozzle is used for injecting hydrolysis solution into the cavity body of the high-shear homogenate pump. In the invention, the nozzle is an elongated rod; holes extending from tail ends to front ends are arranged in the nozzle; a conical surface is formed at the front end of the nozzle and arranged at the back side of a tip arranged at a joint part of the conical surface and the rod body of the nozzle; two or more than two nozzle holes are symmetrically arranged along the conical surface and are communicated with holes in the nozzle; the rod body of the nozzle is arranged in a nozzle holder, and a spring is arranged between the rod body and the nozzle holder; a rear end of the spring is connected with a ring disk; a spring sleeve is arranged at the back end of the rod body of the nozzle and in a cavity between a back end pipe inner wall of the nozzle holder and the ring disk; and the front end of the nozzle holder is hermetically matched with the conical surface at the back side of the tip of the nozzle under the condition that the spring always keeps to provide compression spring force. The invention can effectively prevent the gumming phenomenon from occurring.

Description

technical field [0001] The invention is applicable to a matching injection device on a high-shear homogenate pump used in the polymerization hydrolysis process of the petrochemical acrylic fiber industry, and injects a hydrolysis solution into the cavity of the high-shear homogenate pump through the nozzle. Background technique [0002] Stirring equipment is one of the most common and important unit equipment in chemical engineering and biological engineering. Stirring equipment is often associated with processes such as mixing, reaction, evaporation, and crystallization. According to traditional theories, complex intermediate modulation tanks and reactors are required. [0003] The high-shear homogenate pump is different from ordinary mixing equipment. It can integrate several functions together for a specific production process, and complete multiple operations in the same equipment to achieve multi-functional integration. It has a compact structure and low loss. Less, hi...

Problems solved by technology

In the initial stage of use of the original extinction raw liquid homogenizer pump, the booster pump did not track in time when the spinning was running at a low speed, resulting in a sudden increase in the instantaneous pressure of the raw liquid, resulting in the backflow of the raw liquid to the TiO2 water distribution pipeline, and the phenomenon of gelation and blockage of the TiO2 water distribution pipeline.
