Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil production for polyurethane foam, in particular to a plate-frame filter press device for silicone oil production for polyurethane foam. Background Art

[0002] Silicone oil is a polysiloxane with a chain structure of different polymerization degrees. It is prepared by hydrolyzing dimethyldichlorosilane with water to obtain a primary polycondensation ring body, and then the ring body is cracked and distilled to obtain a low ring body. Then, the ring body, capping agent and catalyst are put together for polymerization to obtain a mixture of various polymerization degrees. Silicone oil can be obtained by removing low-boiling substances through reduced pressure distillation.

[0003] As people's lives continue to change, the use of silicone oil has become more and more common, so the extraction of silicone oil has also become more and more common. However, the refined silicone oil will contain activated carbon impurities. Generally, a filter press is used to remove the activated carbon impurities in the silicone oil before use. The existing plate and frame filter press device for silicone oil is inconvenient to clean the filter cake residue on the filter plate after filtration, and the above problem is not solved. The present invention provides a plate and frame filter press device for the production of silicone oil for polyurethane foam, which can effectively clean the residue on the filter frame.
