Description

Disk plate centrifuge for microbial bacterial agent production

Technical field

Microbial bacterial agent production equipment technology is the utility model is related to, specifically one kind is used for microbial bacterial agent The disk plate centrifuge of production.

Background technology

Microbial bacterial agent refers to that the objective microbes such as effective bacterium after industrialized production expansion is numerous, utilize turf, lightweight carbon The porous material such as sour calcium, bentonite adsorbs the active bacteria formulation that the zymotic fluid of thalline is processed into as adsorbent.This microbial inoculum For agricultural production, there is plant growth-promoting production-increasing function, be provided with variety of crops, improved soil again, recover soil fertility, prevention soil Pass disease, maintain the effect such as rhizosphere microflora balance and degraded poisonous and harmful substances.Agricultural microbial agent can improve agriculture Product yield, improve quality of agricultural product, reduce fertilizer amount, reduce cost, improved soil, preserve the ecological environment.In microorganism In microbial inoculum production process, fermentation largely is participated in using moisture content, the later stage of production needs to use disk centrifugal separator to realize separation of solid and liquid. The rotary drum of existing disk centrifugal separator is mounted in vertical shaft upper end, is rotated at a high speed by motor driving.There is one group to be mutually nested in rotary drum It is stacked in disk.Gap is left between disk and disk.Material to be separated adds rotary drum by the feed pipe positioned at rotary drum center.When When material flows through the gap between disk, residue is separated with clear water under centrifuge effect.This disc centrifuge The side of disk be linear pattern, but because the effect of feed separation depends on rotating speed, diameter and the semi-cone angle of disk, straight line The semi-cone angle of the disk different parts of type is equal, and this results in the stress difference of the different piece material on disc diameter very Greatly, the solid content in material is poorer further away from disk center travelling performance, influences separating effect；Further, since lack effective Material-feeding mechanism, material enter rotary drum in after, it is difficult to be evenly distributed on each disk, have impact on the efficiency of separation.
