Abstract

The invention discloses polyester melt filter element cleaning equipment, and the equipment comprises an alkali washing barrel and an alkali washing hanging basket used for fixing a filter element with an opening facing downwards; a steam heating coil is arranged at the bottom of the alkali washing barrel, and a plurality of bubbling short pipes extending into the filter element are installed on the steam heating coil. The bubbling short pipe is communicated with the steam heating coil, and a plurality of bubbling holes are formed in the bubbling short pipe. Aiming at the technical problems of incomplete cleaning and low efficiency of a melt filter element, the invention provides the polyester melt filter element cleaning equipment, which can improve the cleaning efficiency of the melt filter element, shorten the cleaning time of the melt filter element and reduce the steam consumption at the same time.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a polyester melt filter element cleaning equipment. Background technique [0002] The melt filter element after high-temperature hydrolysis is cooled and disassembled and put into the alkali washing hanging basket one by one, so that the core tube opening of the filter element faces downward, transfer it into the alkali washing tank with a gourd, and clean it with the special cleaning solution for the filter element. Wash away Ti02, catalyst and polymer agglomerates, etc. If the melt filter element is not cleaned thoroughly, the service life of the melt filter element will be short, and the metal remaining in the melt filter element will cause the color of the polyester melt to deteriorate, resulting in downgrade or even unqualified polyester products. [0003] Incomplete cleaning of the melt filter element and low efficiency are common problems, which are usually rem...
