Plate-and-frame filter for chondroitin sulfate processing

Abstract

The invention relates to the technical field of solution filtration. The invention discloses a plate-and-frame filter for chondroitin sulfate processing. The filter comprises a rack, a thrust plate fixed on the rack, a plurality of filter units which are connected to the rack in a sliding manner and can be pressed, and a pressing plate which is connected to the rack in a sliding manner through a compression mechanism. Each filter unit comprises a plate frame, a clarification plate, a PP (polypropylene) film and a screen plate. One PP film, one clarification plate and one plate frame are sequentially arranged on each of the two sides of each screen plate in the direction far away from the screen plate respectively. Each clarification plate is fixed on one side of the corresponding plate frame, and each PP film is attached to the corresponding clarification plate and is in close contact with the corresponding screen plate. Compared with the prior art, a layer of PP film is additionally arranged on each clarification plate of the plate frame, so that one piece of equipment achieves multiple filtration from rough filtration to fine filtration, the clarity is high, and the situation that the equipment is blocked when filtrate enters a subsequent sterile filter is avoided.

Description

technical field [0001] The invention relates to the field of filtering equipment, in particular to a plate and frame filter for processing chondroitin sulfate. Background technique [0002] At present, the plate and frame filter is needed in the process of processing chondroitin sulfate. The plate and frame filter is an ideal equipment for the separation of suspension liquid, solid and liquid. Liquid airtight filtration is used to meet the requirements of fine and semi-fine filtration such as purification, sterilization and clarification. It is light, flexible and reliable, and is widely used in chemical industry, ceramics, petroleum, medical liquid, food, smelting and other industries. Send the floating liquid into each closed filter chamber of the filter machine, under the action of working pressure, the filtrate permeates through the filter membrane or other filter materials, and is discharged through the liquid outlet, and the filter residue is left in the frame to form ...
