Horizontal spiral settling centrifugal separation device of biological enzyme extracting solutions

Abstract

The invention discloses a horizontal spiral settling centrifugal separation device of biological enzyme extracting solutions. The device comprises an adjusting solution tank arranged in the front, and the adjusting solution tank is provided with a feed port, a water inlet, a stirring device, a filtering net, a slag discharging port and a discharge port, wherein the feed port is formed in the front section of the adjusting solution tank, the water inlet is formed in the upper part of the adjusting solution tank, the stirring device is arranged on one side of a feed port of the filtering net, the filtering net is arranged to be inclined to the discharge port, and an acute angle of 70-80 degrees is formed between the filtering net and the bottom of the adjusting solution tank; and the adjusting solution tank is sequentially connected to a screw pump, a throttling valve and a feed port of a horizontal spiral settling centrifugal machine through a connecting pipe. According to the device, the solid-liquid concentration of the separated extracting solutions can reach 40-60%, slag removal is smooth and unblocked, separating solutions are clear, machine washing is not needed in the whole process, the halt operation is reduced, the problems that the horizontal spiral settling centrifugal machine cannot separate high-solid concentration solutions and halting and cleaning are needed because slag cannot be smoothly pushed are solved, and high-concentration continuous solid-liquid separation production is realized.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to equipment for solid-liquid separation and separation and purification of biological enzyme preparations, in particular to a horizontal spiral sedimentation centrifugal separation device for biological enzyme extracts. Background technique [0002] Solid-liquid separation is a common production operation in food, chemical, biological, and pharmaceutical industries. Especially in the production of biological enzyme preparations, most processes need to separate fermentation broth or undergo extraction and flocculation. There will be biological enzymes in the liquid that are effective Composition, also can have impurity and solid components such as colloidal polysaccharide, starch, cellulose simultaneously, its content ranges such as 3-60%. Generally, most manufacturers use centrifugal sedimentation and plate and frame filtration for solid-liquid separation. First of all, they are i...

AI Technical Summary

Problems solved by technology

If the solid concentration fluctuates greatly and the content is high, or the content of colloid, polysaccharide and protein in the separation liquid is high, and it is relatively viscous and thick, the above method will cause clogging, no slag will appear, the clarity of the separation liquid will immediately deteriorate, and it is necessary to stop and rinse Clean, waste of time, such as the solid-liquid separation applied to biological fermentation liquid or extract is more likely to occur, the separation and use effect cannot be achieved, and the application of horizontal spiral sedimentation centrifuge is limited
