AI Technical Summary

Technical Problem

Existing multi-stage reactors for polyurethane resin preparation have dead zones in the stirring, resulting in uneven mixing of materials. In addition, the fixed structure of the filter screen makes it difficult to clean and affects the filtration effect.

Method used

The system employs a combination of a rotating wheel and a transmission ring frame, with a guide sleeve causing the floating plate to float intermittently up and down. Combined with anchor-type paddle stirring, it achieves three-dimensional flow of materials. Additionally, a replaceable filter screen structure is designed for easy cleaning.

Benefits of technology

It improves the mixing efficiency of high-viscosity polyurethane resin and simplifies the maintenance and replacement process of filter screens, thereby improving production efficiency and equipment maintainability.

Abstract

The utility model provides a multi-stage reaction kettle for preparing polyurethane resin, which relates to the technical field of reaction kettles and comprises a reaction kettle main body, and a fixed seat is fixedly mounted on one side of the peripheral surface of the reaction kettle main body; a servo motor is fixedly mounted on the fixed seat; two floating plates are arranged in the reaction kettle main body, a rotating wheel and a transmission ring frame are matched with each other, and a connecting frame is guided and limited by a guide sleeve, so that the two floating plates can intermittently float up and down, materials in the reaction kettle main body are pushed up and down, the materials can be quickly dispersed, and anchor type paddles on the lower layer are matched for continuous stirring; according to the multi-stage reaction kettle for preparing the polyurethane resin, complex three-dimensional flowing of materials is formed in the reaction kettle main body, the mixing efficiency is effectively improved, and the problem that when an existing multi-stage reaction kettle for preparing the polyurethane resin is used, due to the fact that the viscosity of the polyurethane resin is high, a stirring dead zone possibly exists in the reaction kettle through a traditional stirring paddle, and consequently the materials are mixed unevenly is solved.
