Utility model content
The utility model is for solving the problems of the technologies described above, a kind of threonine fermentation liquid pretreatment system is provided, threonine fermentation liquid is sieved, ensure that the silk floccule of threonine fermentation liquid is separated, utilize bacterium Slag treatment device to carry out secondary filter, to filter residue recycling simultaneously.
For realizing above-mentioned technical purpose, the technical scheme taked is: a kind of threonine fermentation liquid pretreatment system, be made up of pretreatment unit and bacterium Slag treatment device, described bacterium Slag treatment device is by the bacterium slag ladle vertically arranged, bacterium pulp pump, multiple stage plate and frame filter press, clear liquid transfer tank, clear liquid pump and bag filter composition, described pretreatment unit is by fermentation tank, blanking pump, pressure curved sieve, oversize transferring box, pocket type filter screen and zymotic fluid storage tank composition, the discharging opening of fermentation tank connects blanking pump, blanking pump is connected with pressure curved sieve by blanking pipe, the lower part of screen of pressure curved sieve is divided and is communicated with fermentation fluid reservoir by pipeline, the sieve upper part of pressure curved sieve is connected with oversize transferring box by pipeline, pocket type filter screen is provided with in oversize transferring box, oversize transferring box is communicated with fermentation fluid reservoir by pipeline, fermentation fluid reservoir is connected with bacterium slag ladle by pipeline, the pipeline that bacterium slag ladle is connected with every platform plate and frame filter press is equipped with bacterium pulp pump, the drain pipe of every platform plate and frame filter press is communicated with clear liquid transfer tank, clear liquid transfer tank is connected with bag filter by clear liquid pump.
The utility model beneficial effect:
1, this pretreatment unit utilizes pressure curved sieve to carry out one-level separation, then carries out secondary separation by transferring box, ensures that the silk floccule in Threonine Fermentation is completely segregated.
2, bacterium slag ladle discharging pump is connected by pipeline with sheet frame, enter sheet frame through pipeline, sheet frame filtrate flow enters clear liquid storage tank through clear liquid relay pump by pipeline to clear liquid transfer tank, and clear liquid enters subsequent processing by bag filter filtration and reclaims, its filter cake produced is shaping, can sell.Threonine bacterium Slag treatment device technique does not use steam in processing procedure, and power consumption is low, and floor space is little.Do not produce sewage and waste gas, treatment effeciency is high, cost-saving, improves treatment effeciency.And a part of threonine comprised can be reclaimed in bacterium slag, add economic benefit.
