Filtering device for organic fertilizer raw materials having undergone enzymolysis

Abstract

The invention relates to the field of organic fertilizer production, in particular to a filtering device for organic fertilizer raw materials having undergone enzymolysis. The filtering device comprises an outer barrel, an inner barrel, a material containing block, a feeding pipe, a partition plate and a filtering mechanism, wherein the inner barrel is mounted in the outer barrel, a discharge portand a filter hole are formed in the side wall of the inner barrel, the discharge port is located in the upper end of the inner barrel, the outer barrel is divided into a filtrate cavity and a residuecavity by the partition plate, and the residue cavity is located above the filtrate cavity; the filtering mechanism comprises a screw rod and a blockage clearing block, the screw rod is rotatably arranged in the inner barrel, the blockage clearing block is in threaded connection with the screw rod, and a hole is formed in the blockage clearing block; a sliding groove is formed in the screw rod inthe axial direction of the screw rod, a sliding block is fixed to the material containing block and arranged in the sliding groove in a sliding mode, and an annular groove is formed in the side wallof the material containing block; the blockage clearing block is located below the material containing block, a push-pull rod is fixed to the blockage clearing block, and the upper end of the push-pull rod makes contact with the material containing block; and the feeding pipe penetrates through barrel walls at one sides of the outer barrel and the inner barrel and can communicate with the annulargroove. With such a technical scheme, leftovers can be filtered in batches.

Description

technical field [0001] The invention relates to the field of organic fertilizer production, in particular to a filtering device after enzymatic hydrolysis of organic fertilizer raw materials. Background technique [0002] The nutrients of liquid organic fertilizers come from animals, plants or minerals. The raw materials for the production of organic fertilizers include animal leftovers. By hydrolyzing the protein in the leftovers, proteinaceous organic nitrogen is converted into water-soluble organic nitrogen and available nitrogen. [0003] Before hydrolyzing the protein in the leftovers, it is necessary to enzymatically hydrolyze the leftovers to obtain an enzymatic solution, and then filter the enzymatic solution to obtain a filtrate containing protein; The enzymolysis solution contains incompletely decomposed scraps. Due to the small pore size of the microporous membrane, the filtration speed is slow, and the membrane is easily blocked. It needs to be cleaned repeatedly...

[0003] Before hydrolyzing the protein in the leftovers, it is necessary to enzymatically hydrolyze the leftovers to obtain an enzymatic solution, and then filter the enzymatic solution to obtain a filtrate containing protein; The enzymolysis solution contains incompletely decomposed scraps. Due to the small pore size of the microporous membrane, the filtration speed is slow, and the membrane is easily blocked. It needs to be cleaned repeatedly during the filtration process, which is inconvenient to operate and is not conducive to large quantities of scraps. material filtration
