Description
Technical field
The utility model relates to a kind of fermentor tank, especially a kind of gas backwash stirring-type liquid spawn fermentation tank.
Background technology
Existing liquid spawn fermentation tank is divided into two kinds of alr modes of mechanical stirring and gas stirring.As shown in Figure 1, the fermentor tank top is provided with agitator motor 18, and fermentor tank inside is provided with agitating vane 19, and agitator motor 18 links to each other with agitating vane 19, and the fermentor tank bottom is provided with intake valve 20.Its alr mode is to drive agitating vane 19 by agitator motor 18 to be rotated, and the gas that is passed into by intake valve 20 is upset, and then driven the liquid-flow of fermentor tank bottom, thereby realize the purpose of stirring.The fermentor tank complex structure of this mechanical stirring mode, cost are higher, and failure rate is also higher.
And no matter gas stirring is upper air mode or lower intake method, ubiquity the relatively poor defective of aeration-agitation effect, especially at 1/3～3/4 place of the internal surface circumference of fermentor tank lower cover, it is the dead angle of gas circulation, dissolved oxygen weak effect not only, and the throw out that has substratum has so just caused pot liquid nutrition inhomogeneous, has affected to a great extent the quality of bacterial classification.
Summary of the invention
The utility model is to have complex structure, cost is higher and mixing effect is poor technical problem for existing liquid spawn fermentation tank, and a kind of simple in structure, cost is lower and mixing effect is good gas backwash stirring-type liquid spawn fermentation tank is provided.
For this reason, the utility model is provided with tank body, tank body is provided with upper cover and lower cover, upper cover is provided with opening for feed, and lower cover is provided with sowing port, and tank interior also is provided with oxygen-supplying tube, the oxygen-supplying tube lower end is provided with the gas dispersion mouth, the top of gas dispersion mouth is provided with pod along the periphery of oxygen-supplying tube, and pod is umbrella shape, and the lower end circumference of umbrella shape pod is adjacent with the internal surface of lower cover.
The preferred technical scheme of the utility model is that upper cover also is provided with strainer and check valve, and the upper end of oxygen-supplying tube links to each other with check valve with strainer.
The further preferred technical scheme of the utility model is that gas dispersion opening's edge oxygen-supplying tube periphery evenly distributes.
The utility model further preferred technical scheme is the umbrella shape pod formation point of contact that contacts with oxygen-supplying tube, and the distance between point of contact and the lower cover is 100mm～400mm; Vertical distance between the lower end circumference of umbrella shape pod and the internal surface of lower cover is 10mm～20mm.
The radius that the further preferred technical scheme of the utility model is the lower end circumference of umbrella shape pod is 1/3～3/4 of lower cover radius.
The external diameter that the further preferred technical scheme of the utility model is oxygen-supplying tube is 12mm～20mm, and internal diameter is 8mm～16mm.
The further preferred technical scheme of the utility model is that upper cover also is provided with tensimeter and vent valve, and lower cover also is provided with wash water valve.
The further preferred technical scheme of the utility model is also to be provided with thermometer hole and visor on the tank body.
The utility model is owing to be provided with the pod of a umbrella shape in tank body, simple in structure with respect to churned mechanically liquid spawn fermentation tank, the while has also been reduced cost; Gas in the utility model oxygen-supplying tube stops at the bottom of tank after disperseing via the gas dispersion mouth again, roll over and upper punch, again be obstructed after flowing to into the pod of umbrella shape, folding and downwards, so that the following liquid of the umbrella cover of pod follows the mobile formation of gas to have the fluid of certain pressure, the slit that forms between the lower cover via the umbrella shape edge of pod and tank body is gone out fast, can take up the throw out of tank base, afterwards from bottom to top motion in tank body has good mixing effect.

Embodiment
Describe with reference to the accompanying drawings embodiment of the present utility model in detail.
As shown in Figure 2, the utility model is provided with tank body 1, and the below of tank body 1 is provided with support 13, the support that support 13 is used for tank body 1.Up and down two portions of tank body 1 are respectively equipped with upper cover 15 and lower cover 16, and upper cover 15 and lower cover 16 are circular arc, and it also can be taper.
Above the bottom of oxygen-supplying tube 8, gas dispersion mouth 10, be provided with pod 9 around the periphery of oxygen-supplying tube 8.9 one-tenth umbrella shapes of pod, Open Side Down.Umbrella shape pod 9 contacts with oxygen-supplying tube 8 and forms point of contact 17, and the distance between point of contact 17 and the lower cover 16 is 100mm～400mm; The lower end circumference of umbrella shape pod 9 is adjacent with the internal surface of lower cover 16, and the vertical distance between them is 10mm～20mm, and radius of a circle is 1/3～3/4 of lower cover radius.
On the sidewall of tank body 1, also be provided with visor 6 and thermometer hole 7, see through the fermentation situation that visor 6 can be observed tank body 1 interior liquid spawn; Can measure the existence temperature of liquid spawn by thermometer hole 7, guarantee a good yeasting.
The below is illustrated the process of the utility model gas stirring:
Gas enters into oxygen-supplying tube 8 through strainer 4 and check valve 14, when gas arrives equally distributed four gas dispersion mouth 10 places of oxygen-supplying tube 8 bottoms, flowing out from four gas dispersion mouths 10 of gas uniform, gas after the dispersion stops via the bottom of tank body 1, roll over and upper punch, again be obstructed after flowing to into the pod 9 of umbrella shape, folding and downwards, so that the following liquid of the umbrella cover of pod follows the mobile formation of gas to have the fluid of certain pressure, go out fast via the slit that forms between the lower cover 16 of the umbrella shape edge of pod 9 and tank body 1, can take up the throw out of tank body 1 bottom, afterwards from bottom to top motion in tank body 1, thus play good gas stirring effect.
The above person of thought; it only is specific embodiment of the utility model; when not limiting the scope that the utility model is implemented with this; so displacement of its equivalent assemblies; or according to equivalent variations and modification that the utility model scope of patent protection is done, all should still belong to the category that the utility model claims are contained.
