The purpose of this utility model provides a kind of bifocal and stirs biochemical reactor, it has solved above-mentioned problems of the prior art and deficiency, avoided material generation unitary rotation phenomenon, reduced the quantity of inside reactor spare, reduce the device interior dead angle, thereby increased the ability that mixes of reactor greatly.

The utility model is achieved through the following technical solutions:

Bifocal of the present utility model stirs biochemical reactor and includes housing, charging aperture, discharge port, motor and transmission drive, the horizontal cross sectional geometry of reactor is an ellipse, two ends are circular or the unequal oval of two ends diameter, and two groups of agitating devices are housed in the reactor; Horizontal cross sectional geometry is that two groups of agitating devices of oval reactor are contained in respectively on two oval focuses, and horizontal cross sectional geometry is that two groups of agitating devices of two ends circle or oval reactor are contained in respectively on the center of circle of two terminal circle.

The agitating device that bifocal of the present utility model stirs biochemical reactor is a kind of or its combination of mechanical type, air-flowing type, liquid streaming; Described mechanical type agitating device is oar blade type or turbine type; Described air-flowing type or liquid streaming agitating device are radial flow or slipstream; Described mechanical type, air-flowing type or liquid streaming agitating device are individual layer, bilayer or 3～6 layers.

Frame for movement, direction of rotation and rotation rotating speed that bifocal of the present utility model stirs two groups of mechanical type agitating devices in the biochemical reactor are identical or inequality; Frame for movement, the flow direction and the flow velocity of interior two groups of air-flowing types of reactor or liquid streaming agitating device are identical or inequality.

The beneficial effects of the utility model are:

Bifocal of the present utility model stirs biochemical reactor can make the stirring capacity in the reactor increase exponentially, reactor can not equipped baffle plate also can make liquid phase be easy to mix, avoid material generation unitary rotation phenomenon, reduced the quantity of inside reactor spare simultaneously, reduced the device interior dead angle, thereby increased the ability that mixes of reactor greatly, energy consumption and cost have been reduced, applicable to high-viscosity material, enlarge the volume and the capacity of reactor at double, can be widely used in Chemical Engineering, bioengineering, pharmaceutical engineering, sizing mixing in food engineering and the environment-friendly engineering, mix, preparation and processing, can make the production technology in these fields bring change, and can design large-scale reactor on this basis, be used for more massive industrial production.
