Description

Technical Field

[0001] The utility model relates to the field of desulfurization pump equipment, in particular to an anti-cavitation structure of a desulfurization pump. Background Art

[0002] Application No. 202122408508.3 discloses a desulfurization pump with an anti-cavitation device. When in use, the inflow pipe of the square box is connected to the gas, the drive motor is started, and the drive motor drives the desulfurization pump body to work. The gas enters the lime water cavity of the square box through the inflow pipe, and then is filtered for the first time through the lime water. The filtered gas is filtered for the second time through the filter component. The filter component filters the gas for physical impurities to prevent the gas from corroding the desulfurization pump body. The filtered gas flows into the desulfurization pump body through the air inlet pipe and is then discharged through the air outlet pipe. When in use, it has the following shortcomings: the square box is connected to the pump body through the air inlet pipe, which makes it inconvenient to disassemble the square box. When the pump body is damaged, the entire internal structure of the square box cannot be used because it cannot be disassembled, which leads to a waste of resources. At the same time, when the gas enters, it is injected through the inflow pipe 7 and contacts with the lime water. The lime water far away from the inflow pipe 7 is difficult to contact the gas, resulting in incomplete gas reaction. Therefore, a device is urgently needed to solve the above problems.

An input pipe 2 is fixed to one side of the pump body 1 through a connecting flange, a sleeve 16 is welded and fixed to one side of the box body 3, a rubber sealing pad is bonded and fixed to the inner wall of the sleeve 16, the sleeve 16 is sleeved on the outside of the input pipe 2, and the contact position between the sleeve 16 and the input pipe 2 is sealed by the rubber sealing pad. A limiting mechanism is provided between the sleeve 16 and the input pipe 2 for conveniently limiting the position of the sleeve 16 and the input pipe 2, a filtering mechanism is provided on one side of the box body 3 for convenient filtering, and a discharge pipe 12 is inlaid and fixed to one side of the box body 3. An injection pipe 6 is movably inserted into the center of the body 3, and a limiting ring 7 is welded and fixed around the outside of the injection pipe 6. There are two limiting rings 7, which are respectively located on the outer wall and the inner wall of the box body 3. A hollow block 14 is movably sleeved on the lower end of the injection pipe 6, and a plurality of extension pipes 15 are welded and fixed on the outside of the hollow block 14. When in use, the gas is injected into the box body 3 through the injection pipe 6 and ejected through the extension pipe 15. At this time, the hollow block 14 in the impact force belt rotates, which plays a stirring role, so that the gas and lime water are quickly and fully mixed, thereby ensuring that the gas is completely reacted with harmful substances.

[0020] The limiting mechanism includes a fixed rod 8, a fixed ring 9, a groove body 10, a movable ring 11 and an extension block 13. The fixed rod 8 is welded and fixed on the pump body 1. There are two fixed rods 8, which are symmetrically fixed on the upper and lower sides of the pump body 1 and extend to the outside of the input pipe 2.
