Filter with multiple bags and precision inserts

Abstract

The invention provides a filter with multiple bags and precision inserts, which is applicable to precision filtering of chemical industries of paint, adhesive, resin, printing ink, cosmetics and the like. The main realization method includes that a filter tank is arranged at first, a filter bag fixing plate is disposed in the filter tank, one or a plurality of filter bags are arranged on the filter bag fixing plate, press plates are replaced by the inserts, edges of the filter bags are pressed on the filter bag fixing plate via the inserts, fixing lug supports are disposed at outer edges of the inserts, filter through holes are arranged on the inserts, insert seats are disposed at the outer edges of the filter bags on the filter bag fixing plate, and each insert is tightly screwed and compacted by an inclined opening between each fixing lug support and a groove of each insert seat, so that the filter bags can be fixedly sealed better.

Description

Technical field: [0001] A multi-bag precision insert filter is suitable for precision filtration of paint, adhesive, resin, printing ink, cosmetics and other chemical industries. Background technique: [0002] The bag filter is a multi-purpose filtration device with a wide range of applications and strong adaptability. In particular, the side leakage rate of the filter bag is small, which can accurately ensure the filtration accuracy, and can quickly replace the filter bag. There is basically no material consumption in the filter, which reduces the operating cost. It is suitable for paint, viscose, resin dye, ink and oil products, Fine filtration of liquids in chemicals and other industries, the filtration fineness is guaranteed by the filter bag, no sampling re-inspection is required in the middle, and it can be assembled with a delivery pump on a mobile cart, so that it can be moved to any production line for filtration at will. Its main structure is as follows: first, a ...

Problems solved by technology

However, no matter it is a single bag or multiple bags, the filter bag is pressed by the pressing sheet to press the edge of the filter bag on the filter bag fixing plate in the filter, so as to fix and seal the filter bag. A number of bolts are also fastened to the filter bag fixing plate. Because of this structure when filtering high-viscosity liquids, due to the infiltration of the liquid, the bolts and pressing pieces are stuck to the filter bag fixing plate, and it is difficult to separate from it. Even damage the filter bag, this situation is especially obvious when the multi-bag filter filters some high-viscosity glue
