Utility model content

The purpose of this utility model is to provide a kind of cooling system of fermentation tank, so greatly improves the cooling effect of material Rate.

Above-mentioned purpose of the present utility model technical scheme is that：A kind of cooling system of tank body, Including the tank body with agitating paddle, the top on the inside of the tank body is provided with circular coil pipe, and the coil pipe is set on agitating paddle, The often circle coil pipe unit of coil pipe is extended to the direction of principal axis of agitating paddle branch pipe one, and the outside of the tank body is provided with circulation Pipe, the circulation pipe is bottom-up is configured.

By using above-mentioned technical proposal, by setting the branch pipe one of the direction of principal axis extension to agitating paddle on coil pipe, this Sample is when material is being lifted up by agitating paddle, and material runs past branch pipe one or coil pipe, so as to ensure that material is uniform While cooled, the quantity of the design of pipeline can also be reduced in addition.Meanwhile, material to tank body wall direction flow when Wait, material can be flowed into circulation pipe, and now material will be flow back into tank body on the outside of tank body, so that also with regard to drawout The area of material, is more beneficial for material and cools down.

It is preferred that, cooling collar is cased with the outside of the circulation pipe, the tube wall of the cooling collar is built with coolant.

By using above-mentioned technical proposal, it is set in outside circulation pipe, so can by the cooling collar with coolant Effectively the material flowed through in circulation pipe is cooled down, so as to also be considerably improved the cooling effectiveness to material.

It is preferred that, the often circle coil pipe unit of coil pipe is provided with branch pipe two to tank skin extension.

By using above-mentioned technical proposal, the setting of branch pipe two is to be reached when material is stirred Jiang Cong centers and is thus lifted to After highest point, and to tank skin direction flow when, also can pass through branch pipe two, so can further to material carry out it is cold But.

It is preferred that, the branch pipe one and branch pipe two are arc setting.

By using above-mentioned technical proposal, it can so expand the flow path of branch pipe one and branch pipe two, so as to endure significantly The cooling effect of coolant in high coil pipe.

It is preferred that, the outer sheath of the agitating paddle is provided with guide shell, and guide shell is located on the outside of the blade of agitating paddle, and and tank Wall is mutually fixed.

By using above-mentioned technical proposal, when agitating paddle is in stirring, guide shell can limit the flowing of material The axle that direction is proximate to agitating paddle is flowed, so that branch pipe one and branch pipe two can be passed through by ensureing the material of the overwhelming majority, And then can improve and greatly improve cooling effectiveness.

It is preferred that, the top edge of the guide shell is upwardly extended provided with flow deflector, the incline direction direction of the flow deflector Branch pipe one.

By using above-mentioned technical proposal, the setting of flow deflector can more accurately be entered with directing material to the direction of branch pipe one Row flowing, so as to also just can more effectively cool down material.

It is preferred that, the lower edge of the guide shell, which stretches out, is provided tiltedly with flange.

By using above-mentioned technical proposal, it can so expand the nozzle of guide shell lower end, so as to also be advantageous for increase Material enters the amount of guide shell, so that the cycle efficieny between being also beneficial to improve material inside and outside the guide shell, so also favourable In the cooling for improving material.

It is preferred that, the surface of the flange is into cambered surface.

By using above-mentioned technical proposal, when the surface of flange can enable the material enter in guide shell for cambered surface It is enough more smooth, advantageously reduce energy loss of the material in flow process.

It is preferred that, the coil pipe is connected with the heat exchanger outside tank body top, and coil pipe is outer with pump at the top of tank body Body, the heat exchanger is mutually fixed with condensate pipe.

, can be by the coolant in coil pipe and the condensed water for flowing through heat exchanger by the pump housing by using above-mentioned technical proposal Heat exchange is carried out, coolant can be so enclosed in inside coil pipe, so as to advantageously reduce the waste of coolant.

It is preferred that, the coil pipe is in there is one section of horizontally disposed pipeline outside the top of tank body, the lower section of the pipeline is provided with Sedimentation pipe, the lower end of the sedimentation pipe and its with being equipped with valve at pipeline connection.

By using above-mentioned technical proposal, because coil pipe is in the process used for a long time, the chip of tube wall will enter cold But in liquid, such chip will cause very big damage to the pump housing when passing through the pump housing.And now coolant is by sedimentation pipe When square, chip is easy for settling down and converged in sedimentation pipe.Now, as long as staff is by the valve above sedimentation pipe Close, and open the valve of lower section, such chip will be drawn off from below.

In summary, the utility model has the advantages that：

1st, the setting of branch pipe one and branch pipe two, expands the area of cooling in tank body, so as to be effectively guaranteed material Uniform cooling；

2nd, guide shell is arranged outside agitating paddle, can so play a part of water conservancy diversion to material, so that material can Towards the flowing of the direction of branch pipe one, be conducive to improving the cooling of material；

The 3rd, sedimentation pipe be set on coil pipe, the chip of coil pipe inwall generation so can have quickly and easily been removed.
