Description

Technical Field

[0001] The utility model relates to the technical field of shielded pumps, in particular to an integrated shielded circulation pump device. Background Art

[0002] The drive of an ordinary centrifugal pump is to connect the impeller shaft of the pump with the electric shaft through a coupling, so that the impeller rotates together with the motor to work. The shielded pump is a seal-free pump. The pump and the drive motor are sealed in a pressure vessel filled with the pumping medium. This pressure vessel has only static seals and a wire group to provide a rotating magnetic field and drive the rotor. This structure eliminates the rotating shaft sealing device of the traditional centrifugal pump, so it can be completely leak-free.

[0003] At present, shielded pumps are equipped with circulation pipes to circulate cleaning liquid. The function of the cleaning liquid is to assist in cleaning the impeller. However, in the prior art, when the cleaning liquid is circulated, it is found that as the use time increases, the cleaning function of the cleaning liquid gradually decreases. The reason is that there are too many impurities in the cleaning liquid. There is no convenient and simple structure in the prior art to purify the cleaning liquid. For this reason, we propose an integrated shielded circulation pump device. Utility Model Content

[0006] By adopting the above technical solution, the liquid can be purified and cleaned when being transported in the circulation pipe, thereby improving the quality of the cleaning liquid, that is, improving the operating efficiency and quality of the canned motor pump.

[0007] The utility model is further configured that liquid ports are provided on both sides of the cleaning tank, and one group of the liquid ports is a liquid inlet, while the other group of the liquid ports is a liquid outlet.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] Integrated shielded circulating pump device, such as Figure 1-4 As shown, it includes a base 1, a mounting piece is fixed to the outer side of the bottom of the base 1, and the mounting piece is connected to the fixed object by bolts, a pump body 2 is installed on the top of the base 1, and a circulation pipe 3 is arranged above the pump body 2, a cleaning tank 4 is connected to the circulation pipe 3 to filter and purify the cleaning liquid, and a filter screen 6 is arranged in the cleaning tank 4;

[0026] Furthermore, in this embodiment, liquid ports 5 are provided on both sides of the cleaning tank 4, and one group of liquid ports 5 is a liquid inlet, while the other group of liquid ports 5 is a liquid outlet;

[0027] In the above records, the connection method between the circulation pipe 3 and the cleaning tank 4 is plug-in type, which is conducive to the disassembly and installation of the circulation pipe 4, thereby achieving the effect of assisting the disassembly and assembly of the cleaning tank 4. In addition, after the circulation pipe 3 is connected to the liquid port 5, the operator can further tighten and limit the connection of the circulation pipe 3 by using clamps and cable ties, thereby ensuring the stability of the connection of the circulation pipe 3.

[0028] See also Figure 3-4 The cleaning tank 4 is composed of three parts, including a first connecting part 41, a second connecting part 42 and a cleaning part 43. Two groups of liquid ports 5 are respectively opened on the first connecting part 41 and the second connecting part 42, and the filter screen 6 is arranged in the cleaning part 43;

[0029] In the above description, the cleaning tank 4 is divided into three parts, each of which is responsible for a certain function, thereby realizing the overall splitting, which is conducive to the efficient cleaning operation of the cleaning tank 4 on the cleaning liquid.

[0030] See also Figure 4A first threaded opening 7 is fixed at the end of the first connecting portion 41, and a first threaded wall 8 threadably matched with the outer wall of the first threaded opening 7 is formed in the inner wall of the cleaning portion 43, a second threaded opening 9 is fixed at the other end of the cleaning portion 43, and a second threaded wall 10 threadably matched with the outer wall of the second threaded opening 9 is formed in the inner wall of the second connecting portion 42;
