Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane resin production, in particular to a polyurethane resin filtering device. Background Art

[0002] Polyurethane (PU), whose full name is polyurethane, is a polymer material with excellent mechanical properties and strong plasticity formed by the polycondensation reaction of polyols and polyisocyanates. After nearly eighty years of technological development, this material has been widely used in products such as coatings, adhesives, fabric finishing agents, leather modifiers, polyurethane soft / rigid foams, elastomers, etc., and is used in the fields of textiles, construction, aviation, shipping, transportation, medicine, electronics, etc. In the production process of polyurethane resin, it needs to be filtered, but the conventional filtering device has a single function and lacks anti-clogging measures, which is not convenient for ensuring the continuity of the production operation of the device and affects production efficiency.

[0003] For example, a polyurethane resin filtering device disclosed in the authorization announcement number CN215462479U includes a box body, the inner top wall of the box body is provided with a feed hopper extending to the top thereof, the inner bottom wall of the box body is provided with a discharge pipe extending to the bottom thereof, and the inner wall of the box body is provided with a mounting frame on both sides. The polyurethane resin filtering device is provided with an adjustment component. When the filter needs to be disassembled, the T-bar is pressed downward to drive the rack plate to move downward along the inner wall of the mounting frame, the rack plate drives the gear meshing with it to rotate, the gear drives the driving frame to move upward along the inner wall of the mounting frame through the eccentric rod, the driving frame drives the end of the driving rod connected to it to move, and the driving rod drives the clamping rod to move toward the inside of the U-shaped plate through the connecting shaft, so that the clamping rod drives the clamping block to move out of the filter, thereby releasing the fixation of the filter, and realizing the disassembly of the filter. However, the structure of the utility model is relatively complex, and it lacks measures to prevent the filter from being blocked, which is not convenient for ensuring the production efficiency of polyurethane resin. For this reason, we propose a polyurethane resin filtering device, which solves the problem of easy blockage of the filter and improves the filtering efficiency, thereby improving the production efficiency.
