A filtration device for producing polyurethane foam materials

Abstract

This utility model relates to the field of polyurethane foam material production technology, specifically to a polyurethane foam material production filtration device, including a housing and a cleaning unit. The cleaning unit includes a rotating shaft, a connecting rod, a right-angle scraper, a spiral blade, a filter plate, a stabilizing frame, a drive motor, an installation assembly, and an infeed / outfeed assembly. In use, the filter plate is fixed to the housing using the installation assembly, and then the polyurethane foam material is poured into the housing. The controller is activated to start the drive motor, generating rotational power that drives the rotating shaft to rotate. At this time, the connecting rod and the right-angle scraper clean the inner wall of the housing to prevent adhesion.

[0002] Rigid polyurethane foam is made primarily from isocyanate and polyether, mixed using specialized equipment with the help of various additives such as foaming agents, catalysts, and flame retardants. Existing polyurethane foaming machines often cause filter clogging due to the high viscosity of polyurethane foam.

[0003] The prior art patent application with publication number CN219783982U discloses a filtration device for the production of polyurethane foam materials, including a polyurethane foaming machine body and a filter tube. The polyurethane foaming machine body is equipped with a filter tube, the filter tube is equipped with a filter screen cylinder, the filter tube is equipped with a fixing mechanism, a cleaning mechanism, and a pressurizing mechanism. The filter tube is equipped with a rotating ring, and the rotating ring is equipped with multiple sets of brush plates. The design can improve the overall convenience and practicality of the filtration device for the production of polyurethane foam materials.

[0004] However, in the aforementioned prior art, polyurethane foam has a high viscosity and tends to adhere to the inner wall of the shell, which affects the filtration of raw materials and subsequent processing and production under long-term use. Utility Model Content
