Abstract
Description
Technical Field
[0001] This utility model relates to the field of circulating pump technology, specifically to a backwashing mechanism for a cooling water circulating pump. Background Technology
[0002] A circulating pump is a pump specifically designed for conveying circulating liquids in reaction, absorption, separation, and absorbent regeneration processes within a system. Its design features a low head to overcome the pressure of the circulating system. It typically employs a single-stage centrifugal pump structure, providing moderate and stable flow with minimal variation. The circulating pump mechanically draws liquid from one location and transports it through pipelines to another, maintaining the liquid's circulation within the system. It is widely used in industry, construction, and HVAC systems, providing efficient liquid transport solutions for various applications. Furthermore, circulating pumps offer advantages such as energy efficiency, durability, no risk of leakage, and low-noise operation.
[0003] The backwashing mechanism of a cooling water circulating pump is an innovative design that achieves self-cleaning through a specific structure. This mechanism typically includes components such as an outlet pipe, a circulation pipe, a rotating component, and an adjusting baffle. When cleaning is required, the rotating component is adjusted, causing the adjusting baffle to block the outlet pipe, forcing water to circulate and flush within the pump head through the circulation pipe. Existing cooling water circulating pump backwashing mechanisms often lack a flow regulation system, resulting in the inability to flexibly adjust the water flow intensity during flushing according to actual needs. This affects the cleaning effect and energy consumption control. Furthermore, the filter screen removal process is usually cumbersome, increasing maintenance difficulty and affecting the frequency of regular inspection and cleaning of the equipment, which may adversely affect the stability of the cooling water circulation system and the pump's operating efficiency.
[0004] Therefore, it is necessary to provide a new backwashing mechanism for a cooling water circulation pump to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a backwashing mechanism for a cooling water circulation pump to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a backwashing mechanism for a cooling water circulating pump, comprising a base, and further comprising:

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention uses a cylinder to move a fixed plate, which in turn moves a connecting plate. The connecting plate then moves a slider along the inner wall of the fixed frame, causing the slider to rotate a connecting rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 As shown, a backwashing mechanism for a cooling water circulation pump includes a base 1 and a pump body 2. The pump body 2 is fixed to the top of the base 1. The water inlet end of the pump body 2 is connected to a water inlet pipe 3. A support pipe 4 is fixed to one end of the water inlet pipe 3. A fixing frame 5 is fixed to the outside of the support pipe 4. The base 1 can fix the pump body 2. The pump body 2 is a cooling water circulation pump in the prior art. The working principle of the cooling water circulation pump is to pressurize the cooling water through the pump body 2 and make it circulate in the system. It will not be described in detail here. The pump body 2 can guide the cooling water into the water inlet pipe 3. The fixing frame 5 can support the support pipe 4 to facilitate the subsequent circulation of cooling water.
[0026] The drive assembly 6 is located inside the fixed frame 5. The drive assembly 6 has a connecting rod 7 inside, and a blade 8 is fixed to the outside of the connecting rod 7. The fixed frame 5 can install the drive assembly 6, which enables the drive assembly 6 to stably drive the connecting rod 7 to rotate, thereby causing the connecting rod 7 to drive the blade 8 to rotate, thus achieving the effect of adjusting the water flow during rinsing and improving the flexibility of the device.
[0027] The adjustment component 9 is located on one side of the support tube 4. The filter screen 10 is fixed inside the adjustment component 9. The support tube 4 can be used to install the adjustment component 9, so that the adjustment component 9 can move the filter screen 10, thereby achieving the effect of easy disassembly of the filter screen 10.
[0028] The outlet pipe 11 is connected to the outlet end of the pump body 2. A clamping plate 12 is provided on the outside of the outlet pipe 11. An adjusting rod 13 is rotatably connected to one side of the clamping plate 12. The pump body 2 can guide cooling water into the outlet pipe 11 and let it flow out. The adjusting rod 13 can drive the clamping plate 12 to move, so that the clamping plate 12 fixes the outlet end of the outlet pipe 11 to the circulation pipe, which facilitates the subsequent installation and disassembly of the circulation pipe.
[0029] The drive assembly 6 includes a cylinder 61 fixed to the inner wall of the mounting frame 5. The piston rod of the cylinder 61 is fixed with a slider 62, and the outer side of the slider 62 is slidably connected to the inner wall of the mounting frame 5. The mounting frame 5 can fix the cylinder 61, enabling the cylinder 61 to stably drive the slider 62 to move, so that the slider 62 slides along the inner wall of the mounting frame 5, which facilitates the subsequent rotation of the connecting rod 7 by the slider 62.
[0030] The adjusting assembly 9 includes a threaded rod 91 rotatably connected to the outside of the support tube 4. A slide tube 92 is threadedly connected to the outside of the threaded rod 91, and the inner wall of the slide tube 92 is fixed to the outside of the filter screen 10. The threaded rod 91 is rotatably connected to the support tube 4, so that the threaded rod 91 drives the slide tube 92 to rotate threadedly, so that the slide tube 92 slides along the inner wall of the support tube 4, which facilitates the subsequent movement of the filter screen 10 by the slide tube 92.
[0031] A support frame 14 is fixed to the top of the base 1, and a support plate 15 is fixed to the top of the support frame 14. The top of the support plate 15 is fixed to the bottom of the fixed frame 5. The base 1 can fix the support frame 14, so that the support frame 14 can fix the support plate 15, which facilitates the subsequent support of the support plate 15 to the fixed frame 5 and improves the stability of the cylinder 61 when it is working.
[0032] The piston rod of cylinder 61 is fixed with a fixing plate 16. A connecting plate 17 is fixed to the outside of the fixing plate 16, and one side of the connecting plate 17 is fixed to the other side of the slider 62. Cylinder 61 can drive the fixing plate 16 to move, so that the fixing plate 16 drives the connecting plate 17 to move, which facilitates the subsequent sliding of the slider 62 along the inner wall of the fixing frame 5 by the connecting plate 17.
[0033] A positioning plate 18 is fixed to the outside of the support tube 4. A connecting plate 19 is fixed to one side of the positioning plate 18, and one side of the connecting plate 19 is rotatably connected to one end of the threaded rod 91. The support tube 4 can fix the positioning plate 18, so that the positioning plate 18 fixes the connecting plate 19, which facilitates the rotatable connection between the connecting plate 19 and the threaded rod 91.
[0034] A fixing seat 20 is fixed to the top of the base 1, and a fixing ring 21 is fixed to the top of the fixing seat 20. The inner wall of the fixing ring 21 is threadedly connected to the outer side of the adjusting rod 13. The base 1 can fix the fixing seat 20, so that the fixing seat 20 fixes the fixing ring 21, which facilitates the subsequent threaded rotation of the adjusting rod 13 and the fixing ring 21.
[0035] Working Principle: When this device is in operation, the operator first connects the circulation pipe to the outlet pipe 11. Then, the adjusting rod 13 is rotated, causing it to rotate along the threaded inner wall of the fixing ring 21. This causes the adjusting rod 13 to move the clamping plate 12, clamping and fixing the circulation pipe and the outlet pipe 11, thus achieving the effect of installing and removing the circulation pipe. The cylinder 61 is then activated, causing it to move the fixing plate 16, which in turn moves the connecting plate 17. The connecting plate 17 then causes the slider 62 to slide along the inner wall of the fixing frame 5, causing the slider 62 to rotate the connecting rod 7. This, in turn, causes the connecting rod 7 to rotate the blade 8, thereby adjusting the water flow during rinsing and preventing the water flow intensity from being unpredictable and unable to meet actual needs. The flexible adjustment improves cleaning efficiency and energy consumption control. Pump 2 is then turned on, allowing cooling water to flow through slide pipe 92 and support pipe 4 into inlet pipe 3. Pump 2 pressurizes the cooling water, directing it to outlet pipe 11. The cooling water in outlet pipe 11 flows into circulation pipe for system circulation. When filter screen 10 needs replacement, threaded rod 91 is rotated, causing slide pipe 92 to rotate threadedly. Slide pipe 92 slides along the inner wall of support pipe 4, coordinating with threaded rod 91 rotating along one side of connecting plate 19. This allows slide pipe 92 to move filter screen 10, facilitating easy disassembly, reducing maintenance difficulty, increasing the frequency of equipment inspection and cleaning, and improving the stability of the cooling water circulation system.
