Background

In the field of petrochemical industry, organic products are generally synthesized by a mixing reaction in a reaction kettle without leaving liquid materials. In order to ensure the mixing effect between the liquids and the reaction efficiency, the reaction process is usually accompanied by stirring. And along with stirring, a plurality of foams are often generated above the liquid surface, and the foams are generated to cause tank overflow accidents, pollute the environment and influence the normal reaction of materials. At present, in order to reduce the generation of foam, a defoaming agent is added into reactants to inhibit the generation of foam. Taking the surfactant produced by us as an example, when no defoaming agent is added, a large amount of foam is generated in the reaction process, and the foam is blown out from the top of the tank body, so that the addition of materials is influenced, and the tank body and the surrounding environment are polluted.

Although the defoaming agent can effectively suppress the generation of foam, the defoaming agent itself acts as an additive and is eventually mixed in the product, which affects the quality of the product. And the antifoaming agent is a disposable practical additive, and the purchasing of the antifoaming agent is also a relatively large expenditure.

The float 4 is integrally connected to the central cylinder 5 and serves as a framework of the device to provide a mounting position for the defoaming component. The floater 4, the central cylinder 5 and the connecting ribs 6 are all insulating parts, so that short-circuit accidents are prevented when the electric stimulation defoaming action is carried out.

In particular, in the present embodiment, the float 4 is displaceable in the vertical direction within the tank 1. The concrete structure is as follows: a plurality of bottom limiting blocks 11 are arranged on the inner wall of the tank body 1, and the bottom limiting blocks 11 can be in contact with the bottom surface of the floater 4 so as to be used as limiting for downward movement of the floater 4. The top limiting block 12 is arranged at the top of the bottom limiting block 11 at a certain distance, and the top limiting block 12 can be in contact with the top surface of the floater 4 and is used as a limit for the floater 4 to move upwards. A limiting sheet 13 is connected between the top limiting block 12 and the bottom limiting block 11, and a slot 41 connected with the limiting sheet 13 in a sliding manner is formed in the outer side of the floater 4. Through the cooperation of the limiting piece 13 and the open slot 41, the vertical movement of the floater 4 in the tank body 1 can be ensured.

Specifically, the width of the slot 41 is greater than the width of the limiting piece 13, so that the float 4 can shake under the limiting of the limiting piece 13.
