Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, in particular to a filtering device for polyurethane foaming agent raw materials. Background Art

[0002] Polyurethane foaming agent is made by mixing black material (isocyanate) and white material (combined polyether). Before preparation, the black material and the white material are usually stored separately. When preparing, the black material and the white material are transported to the discharge gun through a conveying pipe and mixed and sprayed out. Therefore, when storing the raw materials of the polyurethane foaming agent, it is necessary to ensure that there are no large particles or lumps in the raw materials to prevent clogging of the conveying pipe or the discharge gun, so a filtering device is required to filter it.

The polyurethane foaming machine filter device can ensure that the pouring pipe or pouring nozzle is not blocked under the premise of ensuring the particle size of the pouring raw material, and has strong practical significance, but it still has the following disadvantages in actual use:

[0004] 1. The above-mentioned polyurethane foaming machine filtering device filters the raw materials through multiple filter screens arranged inside the filter cavity, but the filter screens are arranged inside the filter cavity. When the filter screens need to be replaced, the entire filter cavity needs to be opened for replacement, which makes replacement inconvenient;
