Description

Technical Field

[0001] The utility model relates to the technical field of pollution cleaning devices, in particular to a pollution cleaning device for a chemical pump. Background Art

[0002] The chemical pump cleaning device is an important auxiliary equipment designed specifically for chemical pumps. Its main function is to remove solid impurities in the pump and pipeline to ensure the normal operation of the pump and the efficient operation of the system. In the chemical production process, since the medium may contain solid particles, it is easy to cause wear, blockage or even damage to the pump. The role of the cleaning device is to clean out these impurities to prevent them from damaging the pump. At the same time, it can also reduce maintenance frequency, extend the service life of the pump, improve production efficiency, and provide strong guarantees for the stable operation of chemical companies.

[0003] According to the search of China Invention Publication No.: CN117167340A, a cleaning device for a chemical pump is disclosed. 1. The present invention is provided with an impeller assembly. When the device is used, power is transmitted from the outside to the input shaft and causes the shaft of the input shaft to rotate. The rotation of the shaft of the input shaft causes the ring plate to rotate and the rotary disc drives the central shaft to rotate through the telescopic rod. The electric cylinder uses the fixed plate and the third bearing to make it independent of the rotation system of the ring plate, and can drive the push shaft to push the rotary disc and the central shaft to extend forward. When the disc drives the impeller to start rotating, the fluid is introduced from the pump housing input port and enters the pump housing. The waste is discharged from the output port. When a large amount of pollutants and impurities adhere to the curved inner wall of the pump housing, its internal volume gradually decreases, and the pressure on the pressure surface of the impeller gradually increases. When the pressure valve setting value is reached, the pressure valve opens, and the fluid enters the pipe of the fixed elbow and causes the corrugated elbow to begin to expand, thereby pushing the slats to rotate around the movable axis, so that the slats rotate ninety degrees and are perpendicular to the impeller. At this time, the brush bar contacts the curved inner wall of the pump housing and begins to brush its inner wall under the rotation drive of the impeller, so that the attached pollutants are separated from the inner wall and discharged. 2. The present invention is provided with an extension component and an impeller component. When the brush bar is reset under the action of the torsion spring, the electric cylinder pushes the center axis forward and drives the impeller forward so that the brush bar contacts the flat inner wall of the pump housing and brushes it under the rotation drive of the impeller. The cleaning direction of this structure can be changed, and the cleaning effect is good.

[0004] However, there are some issues that need to be considered when implementing the above technical solution: First, the device needs to be disassembled and cleaned when it is reused, which has low efficiency. Second, when cleaning, the device uses a brush bar to contact the curved inner wall of the pump housing and starts to brush its inner wall under the rotation drive of the wheel. However, some chemical products have poor fluidity at low temperatures and are difficult to clean, resulting in poor cleaning effect. Utility Model Content
