Embodiment Construction

[0023] figure 1 Shown is the structural principle diagram of the present invention. It is known from the figure that the yellow pulp wastewater discharged from cassava starch production passes through sedimentation tank 1, lift pump 2, reaction sedimentation tank 3, discharge valve 11, sediment stirring tank 6, agitator 8, and slurry storage tank 9. Pressure pump 10——hydraulic plunger mud pump, filter press 12, crusher 13 and dryer 14. The powder after coming out of the dryer 14 is the finished product, which is packaged by the packaging machine as the product . Wherein, in the reaction sedimentation tank 3, the protein precipitant and lime water are respectively injected from the medicine tank 4 and the lime water tank 5, and the protein precipitant and the lime water are mixed with the waste water by the action of water flow, as in the delivery pipe of waste water Add protein precipitant and lime water at the same time, the three liquids are uniformly mixed in the delivery...

Abstract

The invention discloses a system for extracting plant protein from cassava starch wastewater, which comprises a sedimentation tank and is characterized by further comprising a reaction sedimentation tank, a sediment stirring tank, a slurry storage tank, a pressure pump, a filter press, a crusher and a dryer, wherein the bottom surface of the reaction sedimentation tank is conical; a discharge valve is arranged on the conical tip of the reaction sedimentation tank; the sediment stirring tank is provided with a stirrer and is introduced to the bottom of the reaction sedimentation tank to precipitate slurry and inject a flocculating agent, so that the viscosity of sedimentation slurry is reduced; the slurry storage tank is used for storing sediment discharged from the sediment stirring tank; the pressure pump is used for pumping out sediment in the slurry storage tank; the filter press is used for separating water from residues; the crusher is used for thinning filter residues; and the dryer is used for further removing water in filter residues. Yellow slurry wastewater is processed through the sedimentation tank, the reaction sedimentation tank, the sediment stirring tank, the slurry storage tank, the filter press and the like, therefore, plant protein is extracted from the wastewater; wastewater is purified, so that wastewater is beneficial to subsequent biochemical treatment; and favourable conditions are provided for enabling wastewater discharged from production of cassava starch to meet national emission standards.

Description

technical field [0001] The invention relates to a device for extracting solid from liquid, in particular to a system for extracting plant protein from cassava starch wastewater. Background technique [0002] At present, in the process of producing starch from cassava, a large amount of yellow pulp wastewater is discharged, and the yellow pulp wastewater is usually discharged outside after passing through the sedimentation tank. After analysis, the yellow pulp wastewater discharged outside still contains a large amount of vegetable protein, yellow pulp, residual starch and other components. Due to the high water concentration of yellow pulp, mainly plant protein; plant protein is soluble in water and cannot be separated from starch by centrifugation. Plant protein is extremely difficult to degrade, but is easy to oxidize and deteriorate, resulting in poor water quality, and a large amount of discharge pollutes the environment and increases deal with difficulty. The treatmen...
