Technical Field

[0001] The utility model relates to the technical field of filter components, in particular to a triethyl phosphite finished product filtering device. Background Art

[0002] Triethyl phosphite can be used as a plasticizer, lubricant additive and stabilizer, and the raw material of the medical analgesic pizotifen.

[0003] At the end of the triethyl phosphite production process, it is necessary to filter out tiny impurities in the finished liquid. Existing filtration structures usually use pressurization or negative pressure to accelerate filtration. However, the above method usually requires more interfaces to be set on the filter tank to connect to the external air pressure pump structure, and its sealing performance is poor. On the one hand, triethyl phosphite is easy to volatilize and cause safety hazards. On the other hand, gas is easily mixed into triethyl phosphite under the action of air pressure, which reduces the purity of the finished product.

[0004] For this reason, we propose a triethyl phosphite finished product filtering device to solve the existing problems. Utility Model Content
