Utility model content

For addressing the above problem, the utility model proposes a kind of magnetic motive force stirred fermentor, the bacterial classification that the controlled alternating magnetic field of application low frequency is magnetic microcapsules provides periodically reciprocating power of horizontal direction, the temperature difference of utilizing condensing works and bed material provides the power of vertical direction motion for bacterial classification, thereby reaches the object that bacterial classification stirs.

For achieving the above object, the technical solution of the utility model is: a kind of magnetic motive force stirred fermentor, comprise tank body, feeding mouth, discharge port, inlet mouth and venting port are installed on tank body, also comprise the condensing works that is arranged on inner tank wall and the electro-magnet that is fixed on tank wall;

Described condensing works comprises water inlet pipe, rising pipe and a plurality of coolship, on coolship, be provided with conduction hole, between each coolship, by pipe connecting, be communicated with, the side inner wall sleeve of tank body is connected on the side outer wall of coolship, and the side inwall of tank body and the side outer wall of coolship offset;

Tank wall between two adjacent coolships, two coolships adjacent with this forms the first interior compartment; At the coolship of the end of condensing works, the tank body diapire relative and adjacent with this coolship and the tank wall between this tank body diapire and this coolship, form the second interior compartment;

Described electro-magnet is arranged on the side outer wall of the first interior compartment and the second interior compartment.

Further, described pipe connecting is rectangular cylinder.

Further, a coolship in a plurality of coolships of condensing works is provided with water-in, and a coolship in a plurality of coolships of condensing works is provided with water outlet; Described water-in and water outlet connect respectively water inlet pipe and rising pipe, and water inlet pipe and rising pipe stretch out tank body by the opening on tank body, this opening and water inlet pipe and rising pipe seal welding.

Further, described water-in is arranged on the coolship of an end of condensing works, and described water outlet is arranged on the coolship of another end of condensing works.

Further, in the outer cover of tank body, a body skin is housed, between described body skin and tank body, passes through air insulated.

Beneficial effect: the utility model directly utilizes fermented bacterium to do periodically reciprocation cycle motion in alternating magnetic field, realize the stirring of bacterial classification in fermentor tank, compare with prior art, the utility model does not exist mechanical type stirred fermentor owing to using agitator to cause the problem of the shearing force of its generation to microbial destruction, do not exist airlift fermentor to require larger problem to the inlet of gas yet, therefore, the utility model provides a kind of fermentor tank little to microbial destruction, and fermentor tank is applicable to microorganism that oxygen requirement is little or the fermentation of anaerobion.

Suitable magnetic has promoter action, the utility model that electro-magnet formation alternating magnetic field is installed on the outer side wall of interior compartment to the growth division of cell, can be magnetized bacterial classification, therefore, has shortened to a certain extent fermentation time.

The utility model arranges condensing works, because exothermic temperature in fermentation reaction is 5～10 ℃ of left and right, utilizes condensing works to realize the heat exchange between cold and hot fluid, thereby produce the auxiliarypower on vertical direction at interior compartment, to strengthen the exercise intensity of bacterial classification, realize well-beaten object.
