Abstract

The utility model relates to a volute type mechanical defoaming device. A motor is connected with a purified air outlet through a rotary shaft mechanical sealing member, a rotating drum is provided with a foam outlet, a cyclone separator is provided with a foam air inlet, besides, the lower end of the cyclone separator is provided with a material liquid return pipe port. Air having a great deal of foam passes through the inlet and is primarily separated in the cyclone separator; material liquid returns to a fermentation tank through the material liquid return pipe port, and the air having the foam enters the rotating drum which is rotated at high speed; under the function of centrifugal force, the foam is broken, purified air is exhausted through the purified air outlet arranged on a motor base, the material liquid is exhausted to a volute barrel body through exhaust holes of the rotating drum after the foam is broken and the foam liquid returns again to the fermentation tank through the outlet. The utility model is simple in structure and convenient in operation; the utility model has no suppressing action on microorganism fermentation and can increase the quality and the quantity of fermentation products and reduce the cost of the fermentation products, and the utility model has high defoaming efficiency. Therefore, the utility model can be extensively suitable for fermentation tanks for microorganism fermentation.

Description

The scroll casing type mechanical defoaming device

Affiliated technical field:

The utility model relates to the abatement apparatus that a kind of scroll casing type mechanical defoaming device, especially microorganism produce a large amount of foams during the fermentation.

Background technology:

Prior art is in fermentation process, owing to ventilate to stir and the effect of the carbon dioxide that microbial metabolism produces, nutrient solution can produce a large amount of foams, causes that easily escaping liquid causes waste and pollution; The wushu froth breaker is set in traditional microorganism fermentation tank, consumes a large amount of energy consumptions, defoaming effect is very low, flee for fear of foam, add expensive defoamer during the fermentation, defoamer has inhibitory action to microbial fermentation, influences the quality of tunning.

Summary of the invention:

The purpose of this utility model provides a kind of scroll casing type mechanical defoaming device, and it is to adopt mechanical energy with the foam fragmentation, and feed liquid is separated with wind, to microbial fermentation unrestraint effect, improves the quality and the output of tunning, reduces the cost of tunning.Take dual mode to eliminate foam: the one, foam turns back to a part of liquid in the fermentation tank along with the wind that effluxes enters cyclone separator; The 2nd, have the rotary drum of the wind of foam through the high speed rotation, the foam fragmentation is discharged the scroll casing type mechanical defoaming device through the outage of rotary drum, zymotic fluid turns back to fermentation tank, does not discharge the scroll casing type mechanical defoaming device with the clean wind of foam.

The utility model takes following technical scheme to realize, it is to be made of motor and cyclone separator and rotary drum, be connected by the rotor axis mechanical containment member between motor and the clean wind outlet, the foam solution outlet is set on the rotary drum, the foam wind inlet is set on the cyclone separator, and the cyclone separator lower end is provided with feed liquid and returns the mouth of pipe.The wind that will have a large amount of foams during use is through import, in cyclone separator, carry out just separating, feed liquid is returned the mouth of pipe by feed liquid and is turned back in the fermentation tank, the wind that has foam enters the rotary drum of rotation at a high speed, under action of centrifugal force, foam is broken, and clean wind is discharged through the clean wind outlet of motor base (frame), feed liquid is discharged in the spiral case cylindrical shell by the relief hole of rotary drum after the foam fragmentation, turns back in the fermentation tank once more through the outlet of spiral case cylindrical shell foam solution.

Effect of the present utility model is simple in structure, and is easy to operate, to microbial fermentation unrestraint effect, improves the quality and the output of tunning, reduces the cost of tunning, and foam is eliminated the efficient height, is widely used on the fermentation tank of microbial fermentation.
