Abstract

The utility model discloses a biochemical reactor which belongs to the field of chemical equipment. The biochemical reactor comprises a shell body, a charging opening, a discharging opening, a motor and a transmission driving device. The horizontal section of the reactor is ellipsoidal, round at the two ends, or oval with different diameter at the two ends. Two groups of stirring devices are arranged in the reactor; particularly speaking, the two groups of stirring devices of the reactor with the ellipsoidal horizontal section are respectively located on two focuses of the ellipsoid, or the two groups of stirring devices of the reactor whose horizontal section is round or oval at the two ends are respectively located on the center of the circles at the two ends, so as to solve the problems and disadvantages in the prior art, avoid entire rotation of materials, reduce the number of internal pieces of the reactor, and reduce internal dead corners of the equipment, thereby greatly improving the stirring and mixing capabilities of the reactor.

Description

Biochemical reactor

Technical field

The utility model belongs to the chemical industry equipment field, relates to a kind of biochemical reactor, stirs biochemical reactor more specifically to a kind of bifocal.

Background technology

The cross section of the reactor that traditional band mixes all is circular, general installation one or one group of agitator in the reactor.Because single agitator is subjected to the restriction of aspects such as power, material, working ability, its size and stirring capacity are limited, thereby have limited the expansion of cylindrical reactor; Simultaneously because unitary rotation can take place in the liquid phase material of hydrostatic column, cause the system incomplete mixing, the unitary rotation that baffle plate can prevent that just this liquid from flowing need be installed on container inner wall, because the existence of baffle plate, liquid stream produces effect of impact and consumes a large amount of kinetic energy at container edge; Also can there be the dead angle in baffle plate and brings other problem in addition, has so not only increased equipment, investment, energy consumption, manpower, and production efficiency also reduces greatly.

Summary of the invention

The purpose of this utility model provides a kind of 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:

Biochemical reactor of the present utility model includes housing, charging aperture, discharge port, motor and transmission drive, and 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 of biochemical reactor of the present utility model 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 layer.

The beneficial effects of the utility model are:

Biochemical reactor of the present utility model 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.
