Description

Multi-shaft multistage magnetic submerged jet mixing pump

Technical Field

The utility model belongs to the technical field of the magnetic drive pump, in particular to multistage magnetic force submerged injection agitator pump of multiaxis.

Background

Radioactive waste liquid formed in nuclear industry or related nuclear activities forms a precipitation layer with a certain thickness when being stored in an underground waste liquid storage tank for a long time, and the precipitation layer needs to be removed together when the radioactive waste liquid is removed, so that the precipitation layer needs to be stirred and diluted firstly.

Common stirring methods include impeller stirring and jet stirring. Impeller stirring is a frequently used mode in the process of mixing mechanical system media, and axial flow, rotational flow and turbulent flow are generated on the surrounding media through an external rigid contact type stirring impeller, so that the stirring and mixing effects are achieved. The jet stirring is to jet out the pressurized suction fluid through an internal impeller to achieve the purpose of flushing and diluting the medium.

The transmission shaft for transmitting the stirring power has two forms of mechanical seal and magnetic seal. Mechanical seal is the movive seal, carries out radial seal to the rotation axis through the sealing washer of various forms, and sealing medium axial flow appears leaking easily along with the lapse of time, causes the pollution and brings the safety risk for operational environment to the maintenance is frequent. The magnetic seal consists of an outer magnetic rotor, an isolation sleeve and an inner magnetic rotor, the isolation sleeve seals the inner magnetic rotor and a medium in a working cavity, the motor drives the outer magnetic rotor, the outer magnetic rotor drives the inner magnetic rotor to operate by utilizing the magnetic coupling characteristic, the purpose of non-contact torque transmission and the static sealing effect are realized, the medium leakage is completely avoided, and the problems existing in mechanical seal are solved.

The stirrer must penetrate through the small hole of the flange into the storage tank to stir, which is limited by the environment and the use condition for removing the radioactive waste liquid. The shape and the stirring effect of the impeller stirrer cannot meet the use requirements of the scenes. The jet agitator has compact appearance structure due to no external stirring impeller, can meet the installation requirement, and is feasible in principle, but in actual use, because the agitator is fixedly arranged, the jet angle is fixed, and a jet dead angle exists, so that the precipitated substances at the part position in the storage tank can not be uniformly stirred, the stirring effect is not ideal, the length of the existing jet agitator is determined, the ideal stirring effect can not be obtained for the waste liquid storage tank with shallow depth or deep depth, and meanwhile, the performance of the conventional jet agitator is not suitable for being used in a radioactive environment.

In order to solve the problems of environmental pollution and personnel injury caused by leakage of radioactive waste liquid, the clear liquid in the radioactive waste liquid pool is used for circularly sealing and stirring the precipitation layer, and the structure of the existing stirring device is necessary to be optimized and improved for achieving the purpose of efficiently stirring the radioactive waste liquid precipitation layer.
