Abstract

The utility model discloses a defoaming device, which utilizes airflow air flow to smash foam in a special tube chamber under definite pressure to restore the foam to material liquid in order to spray out of the tube chamber, and the foam can be further smashed by an impeller which rotates under the action of the air-current in the front end of the device in order to flow back to a tank. The device has the advantages of simple manufacturing process, no bacterial contamination and environmental protection.

Description

Foam eliminating machine

The utility model relates to a kind of defoaming device, the foam eliminating machine that uses in especially a kind of sweat

At present, at glutamic acid, protease, in the zymotechniques such as amylase, produce a large amount of foams inevitably, these foams must be removed, traditional anti-foam method is machinery and chemistry and uses, its shortcoming is: mechanical de-bubble is installed rake formula scraper plate in the tank level upper end, surperficial bulla is broken into vesicle, and the result still removes and does not fall chemical defoamer de-bubble cost height, the while contaminated feedstock, also contaminated environment, the someone has designed a kind of mechanical defoaming device, and it is by paddle, the rotating cylinder of tape slit-like hole, the commentaries on classics of orifice plate and band porous fin wait composition, by the rotation of having changeed foam got rid of to the froth breaking wall, under the effect of paddle foam is smashed, its froth breaking effect mainly is that bulla is broken into vesicle, bad processing on the problem of eliminating vesicle, vesicle is difficult for eliminating often along with paddle and rotor rotation.

The purpose of this utility model is to provide a kind of defoaming device foam eliminating machine, this foam eliminating machine utilizes the suction effect in constant velocity spiral theorem and the mechanics to design, and the air blast that forms by constant velocity spiral will be smashed by the foam that negative pressure sucks and be reduced to liquid and play the froth breaking effect.

The utility model realizes that in the following manner it comprises shell, connection suction pipe, impeller and a cover air bag part, a cover jet pipe part, and air bag partly comprises air bag and air supply pipe, the spout portion branch comprises suction pipe spiral, spray chamber spiral, jet pipe spiral; Suction pipe spiral inwall has helical, and spray chamber spiral inner and outer wall all has helical, and the outer wall of jet pipe spiral has helical, three parts are linked together by helical, form small one and large one two spray chambers, are through holes in the middle of the jet pipe spiral, communicate with two spray chambers, big spray chamber front end has nozzle, and spray nozzle front end has impeller, and air bag one end is connected with the suction pipe helixseal, one end is connected with the jet pipe helixseal, middle and air supply pipe joins, and all helicals are constant velocity spiral, and three's pitch equates.

After adopting this result, the utility model short in this world rapidly, dispose completely with a large amount of foams, saved material resources, simplify process, effectively controlled foam height, improved the utilization rate of fermentation tank greatly, reduce the microbiological contamination chance, guarantee product quality, play environmental-protection function simultaneously.

Be described in further details below in conjunction with specific embodiment.

Accompanying drawing is a structural representation of the present utility model.

As can be seen from the figure, jet pipe spiral 13 back termination suction pipes 3, suction pipe 3 connects suction inlet 4, and jet pipe spiral 13 passes in the middle of air bag 2, and front end has constant velocity spiral, constant velocity spiral has spray chamber spiral 12 outward, constant velocity spiral is all arranged inside and outside the spray chamber spiral 12, and spray chamber spiral 12 skins are suction pipe spirals 6, in the suction pipe spiral 6 constant velocity spiral are arranged, article four, constant velocity spiral links, there is very little helical slit the centre, and jet pipe spiral 13 is shorter than spray chamber spiral 12, and front end forms spray chamber 10, spray chamber spiral 12 is shorter than suction pipe spiral 6, form spray chamber 5, air bag partly comprises air bag 2 and air supply pipe 1, the front end of air bag 2 and suction pipe spiral 6 sealed attachment, the external diameter sealed attachment of rear end and jet pipe spiral 13, connect air supply pipe 1 below, the front end of spray chamber 5 has nozzle 9, and there is impeller 8 nozzle 9 fronts, be fixed on the shell 11 by support 7, air supply pipe 1 is connected on the steam line of fermentation tank.

During operation, after the gas of certain pressure enters air bag 2 from air supply pipe 1, flow in slit along two constant velocity spirals,

directive spray chamber

10 and 5, along after directive spout 9 again, at this moment in

spray chamber

10 and 5, form negative pressure, foam is along suction inlet 4, the rapid

inspiration spray chamber

10 and 5 of suction pipe 3 quilts, under the effect of the air blast of constant velocity spiral, the directive impeller 8 that is crashed to pieces, impeller 8 is fast rotational under the effect of spiral liquid, and the broken foam that ejects is further pulverized, be reduced to feed liquid liquid and go in the jar, finish the froth breaking process.
