Description

Technical Field

[0001] The utility model relates to the technical field of water transfer paper processing, in particular to a high-pressure filtering device and equipment for water transfer paper glue. Background Art

[0002] In the production process of water transfer paper, before the gelatinized glue is transported to the roller coating equipment, it is necessary to filter the glue to remove impurities, so as to remove larger impurity particles or agglomerated insoluble matter in the glue, etc., so as to reduce the granularity of the slurry and improve the fineness of the glue, thereby ensuring that the water transfer paper after roller coating has a higher quality.

[0003] At present, common filtering methods usually require the use of single-bag or double-bag high-pressure filters to perform high-pressure filtration on the gelatinized glue liquid; however, since the traditional high-pressure filter only uses one liquid inlet pipe to transport the glue liquid from the liquid inlet pipe to the filter bag through the self-overflow of the glue liquid, and the viscosity of the gelatinized glue liquid is high, the fluidity of the glue liquid is poor, so there is a problem of low efficiency of filling multiple filter bags with glue liquid; further, for example, when a single-bag high-pressure filter is used to filter the gelatinized glue liquid, it is easy for too many impurities to clog the filter bag or filter cartridge, resulting in a small effective filtration area of ​​the filter bag, resulting in a slow filtration efficiency of the entire high-pressure filter, and the high-pressure filter needs to be frequently maintained.
