Description

Technical Field

[0001] This utility model relates to the field of circulating pump technology, specifically to a desulfurization circulating pump. Background Technology

[0002] A circulating pump is a type of pump that uses an electric motor to circulate and transport fluids. In the process of combustion and emission of flue gas in thermal power plants, flue gas desulfurization circulating pumps are often used to desulfurize the flue gas.

[0003] Chinese Patent Application No. CN202323054561.3 discloses a desulfurization circulating pump, including a pump body and a mounting base located at the bottom of the pump body. The pump body has a fluid inlet and a fluid outlet on both sides. The mounting base is fixedly installed on the ground. The bottom of the pump body has a downwardly extending mounting sleeve. The mounting base has a protruding mounting post. The mounting sleeve is movably fitted onto the mounting post. Multiple positioning components connecting the mounting sleeve and the mounting base are detachably installed between the mounting sleeve and the mounting base.

[0004] Although the aforementioned patents can solve the corresponding technical problems, they still have certain objective defects in use:

[0005] Before the fluid enters the fluid inlet, impurities in the fluid cannot be filtered multiple times, which cannot reduce the amount of impurities adhering to the inside of the desulfurization circulating pump. As a result, abnormal noise and / or wear of the desulfurization circulating pump cannot be reduced, which is detrimental to the normal use of the desulfurization circulating pump. Utility Model Content

[0006] The purpose of this invention is to provide a desulfurization circulating pump that addresses the shortcomings and deficiencies of existing technologies.

[0008] A desulfurization circulating pump includes a pump body, with a fluid inlet and a fluid outlet on both sides of the pump body, and also includes a multi-filtration and desorption device. The multi-filtration and desorption device is disposed on the pump body and is used to filter impurities in the fluid multiple times before the fluid enters the fluid inlet, so as to reduce the adhesion of impurities in the fluid to the inside of the desulfurization circulating pump, thereby reducing the occurrence of abnormal noise and / or wear of the desulfurization circulating pump.

[0009] The multi-filtration desorption device includes a connecting ring seat, which is disposed on the pump body and located outside the left end of the fluid inlet;

[0010] An extension ring seat is provided on the left end face of the connecting ring seat;

[0011] A support ring plate, which is slidably disposed inside the extension ring seat;

[0012] A deceleration mesh plate is disposed on the left end face of the support ring plate. The deceleration mesh plate is used to slow down the flow rate of the fluid after it enters the extension ring seat and allow the fluid to pass through.

[0013] A first filter screen is disposed on the deceleration plate and located inside the support ring plate. The first filter screen is slidably engaged with the support ring plate and is used to filter the fluid after the flow rate has been reduced by the deceleration plate.

[0014] The second filter screen is disposed on the inner wall of the support ring plate and is located to the right of the first filter screen. The second filter screen is used to filter the fluid after it has been filtered by the first filter screen.

[0015] A connector is disposed between the extension ring seat and the support ring plate;

[0016] A connector is disposed between the slowing mesh plate and the first filter screen.

[0017] A further improvement is that the connecting member includes an annular groove, which is formed on the inner wall of the extended annular seat;

[0018] Several compression springs, one end of which is fixedly mounted on the extension ring seat, are arranged horizontally, and the compression springs are equidistantly arranged on the extension ring seat;

[0019] A connecting ring plate, one end of which is fixedly mounted on the support ring plate, and the other end of which is fixedly mounted on the other end of the compression spring.

[0020] The ultra-high molecular weight polyethylene (UHMWPE) ring plate has wear resistance, corrosion resistance, and self-lubricating properties. The UHMWPE ring plate is disposed on the inner wall of the extended ring seat and is located on the left side of the ring groove. The UHMWPE ring plate is configured to cooperate with the support ring plate.

[0021] A further improvement is that the connecting ring seat includes a connecting ring seat body, which is disposed on the pump body and located outside the left end of the fluid inlet;

[0022] A sealing layer is fixedly disposed on the end face of the connecting ring seat body near the pump body.

[0023] A further improvement is that the connector includes several connecting rods, which are disposed between the slowing mesh plate and the first filter screen.

[0024] A further improvement is that the damping mesh plate is connected to the support ring plate by several bolts.

[0025] A further improvement is that the horizontal distance between the first filter and the slowing mesh is smaller than the horizontal distance between the second filter and the first filter.

[0026] After adopting the above technical solution, the beneficial effects of this utility model are as follows: before the fluid enters the fluid inlet, impurities in the fluid can be filtered multiple times, which can reduce the adhesion of impurities in the fluid to the inside of the desulfurization circulation pump, thereby reducing abnormal noise and / or wear of the desulfurization circulation pump, which is conducive to the normal use of the desulfurization circulation pump.

[0038] The first filter 8 is disposed on the slowing mesh plate 7. The first filter 8 is located inside the support ring plate 6 and is slidably engaged with the support ring plate 6. The first filter 8 is used to filter the fluid after the flow rate has been slowed down by the slowing mesh plate 7.

[0039] The second filter 9 is disposed on the inner wall of the support ring plate 6. The second filter 9 is located to the right of the first filter 8. The second filter 9 is used to filter the fluid after it has been filtered by the first filter 8.

[0041] A connector is provided between the buffer plate 7 and the first filter screen 8. A connecting flange is provided on the outer left end of the extension ring seat 5.

[0042] The horizontal distance between the first filter screen 8 and the slowing mesh plate 7 is less than the horizontal distance between the second filter screen 9 and the first filter screen 8; the mesh count of the second filter screen 9 is greater than or equal to the mesh count of the first filter screen 8.

[0043] The connecting component includes an annular groove 10, which is formed on the inner wall of the extension ring seat 5;

[0044] Several compression springs 11 are provided, with one end of each compression spring 11 fixedly mounted on the extension ring seat 5. The compression springs 11 are horizontally positioned and are equidistantly arranged on the extension ring seat 5.
