Description

Technical Field

[0001] The utility model relates to the field of filtering equipment, in particular to an impurity filtering device for polyurethane potting glue. Background Art

[0002] The impurity filtering device for polyurethane potting glue plays a vital role in the production process of polyurethane potting glue. It can effectively filter out impurities in the potting glue, improve the quality and purity of the potting glue, and ensure the stability and reliability of subsequent production of electronic components and other products.

[0003] Polyurethane potting glue usually has good bonding and adhesion, which is determined by its molecular structure and chemical composition. However, the fluidity of polyurethane potting glue is also one of its important physical properties. Under appropriate temperature and pressure, polyurethane potting glue can maintain good fluidity, so that it can smoothly pass through the interface into the interior of the filtering device. However, when the temperature is inappropriate and the material fluidity is poor, its own characteristics enable the polyurethane potting glue to be firmly bonded to the material in contact with it. Therefore, in the process of the polyurethane potting glue raw material entering from the equipment interface, it may cause the raw material to adhere to the inner wall of the inlet of the impurity filtering device for a long time. In order to reduce the probability of adhesion and facilitate cleaning after the raw material adheres, an impurity filtering device for polyurethane potting glue is proposed. Utility Model Content

The smooth inner wall of the built-in interface can reduce the probability of adhesion, and during installation, one end of the built-in interface is extended from the feed port into the feed port, so that when the raw materials are introduced, direct adhesion to the pipe wall of the feed port can be prevented, and the probability of adhesion to the inner pipe wall of the feed port is further reduced. At the same time, the material guide interface can be disassembled to facilitate the cleaning of the raw materials accumulated on the inner wall of the material guide interface, thereby ensuring the overall application effect.
