A self-cleaning solvent-free polyurethane processing reactor

Technical Field

The utility model relates to the technical field of solvent-free polyurethane processing, in particular to a self-cleaning solvent-free polyurethane processing reaction kettle.

Background Art

Solvent-free polyurethane adhesive is a kind of adhesive made of polyurethane polymer and solvent-free additives. It has excellent bonding strength and stain resistance. It can melt at low temperature and can meet the bonding needs of users to the greatest extent. It is the best choice in the fields of material technology, home decoration, electronic products, automobile manufacturing, etc. Solvent-free polyurethane adhesive is usually processed in a reactor.

At present, when solvent-free polyurethane adhesive is processed by a reactor, adhesive liquid will adhere to the inner wall of the reactor. Since the existing reactors generally do not have self-cleaning ability or have poor self-cleaning ability, they are usually cleaned manually by manually opening the reactor cover door or flushing the inner wall of the reactor from the feed port of the reactor. However, this cleaning method requires manual continuous flushing of the reactor in multiple directions, which is relatively cumbersome and has low cleaning efficiency. For this reason, we have designed a self-cleaning solvent-free polyurethane adhesive processing reactor to solve the above problems.

Utility Model Content

The purpose of the utility model is to solve the problems in the prior art that the cleaning operation of the existing reactor is relatively cumbersome and the cleaning efficiency is low, and a self-cleaning solvent-free polyurethane processing reactor is proposed. During the processing, the materials can be mixed evenly. At the same time, the scraper rotates with the stirring rod to clean the inner wall of the reactor body and reduce the adhesion of the materials on the inner wall of the reactor body. When the processing is completed and the inside of the reactor body is cleaned, the flushing component, the stirring component and the scraper can work together to fully clean the inner wall of the reactor body.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

A self-cleaning solvent-free polyurethane processing reactor comprises a reactor body, a discharge pipe is installed through the bottom of the reactor body, an annular cover plate is installed on the upper end of the reactor body, a feed pipe is installed through the annular cover plate, a circular cover plate adapted thereto is rotatably connected inside the annular cover plate, a flushing assembly is installed through the circular cover plate, a stirring assembly is installed through the circular cover plate, a scraper abutting against the inner side wall of the reactor body is installed on the side wall of the stirring assembly, and a driving assembly for driving the stirring assembly to rotate is installed on the annular cover plate.
