Description

Technical Field

[0001] The utility model relates to the technical field of polyester polyol production, in particular to a filter for polyol production. Background Art

[0002] Polyester polyols include conventional polyester polyols, polycaprolactone polyols and polycarbonate diols, which contain ester groups or carbonate groups. However, the polyester polyols usually referred to are polyester polyols obtained by polycondensation of dicarboxylic acids and diols. In the prior art, the filter screen in the filter device cannot be disassembled and cleaned. If used for a long time, the filter screen may become clogged, affecting the operation of the filter device.

[0003] For example, the publication number CN202321577123.2 discloses the "Filter for Polyester Polyol Production", which uses a high-pressure air pump to drive other nozzles to spray out, thereby blowing away impurities attached to the filter, thereby cleaning the filter. The filter can be cleaned without disassembly, which is more convenient and efficient, and improves efficiency.

[0004] When the polyol is filtered through the filter plate, the polyol is only filtered once, which may easily lead to the problem of incomplete filtration of the polyol, thereby affecting the quality of the polyol and being detrimental to the subsequent use of the polyol. Utility Model Content
