The conveniently installed circulation pump for water treatment includes a circulation pump and a water quality cleaning system. The first transmission component and the third transmission component are used to conveniently clean the sundries inside the circulation pump, and the second transmission component facilitates the operation of the first transmission component and the third transmission component. A turbine is installed on the surface of one end of the magnetic secondary shaft II. In the present invention, when the turbine rotates, the particulate matter adsorbed on the impeller is blown, and then flows out from the cleaning conduit along with the water flow.

Particulate matter is one of the main reasons for the decline in water quality, so keeping the impeller clean is crucial for improving water quality.

Description

Technical Field

[0001] The present invention relates to the technical field of circulation pumps, and particularly to a circulation pump for water treatment that is conveniently installed. Background Art

[0002] The circulation pump for water treatment is an important device. It generates power to make water circulate in the system, thereby enhancing the oxygen content and mixing degree of the water body. Regarding the basic structure and working principle of the circulation pump, the circulation pump mainly consists of parts such as a motor, a pump body, and an impeller. The circulation pump drives the impeller to rotate through the motor, thereby generating power and making water flow in the pump body. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge of the impeller, the flow rate increases, and the kinetic energy also increases accordingly. When the liquid enters the pump casing, since the flow path in the volute-shaped pump casing gradually expands, the liquid flow rate gradually decreases, and a part of the kinetic energy is converted into static pressure energy. Thus, the liquid flows out along the discharge port at a higher pressure.

[0003] [[ID=ll]]During the use of the existing circulation pump for water treatment, there are flocs and particulate matters and other impurities in the water quality. The filter screen is an important part of the circulation pump and is used to filter impurities in the water. When a large amount of flocs are wound around the outer side of the filter screen, it will seriously affect the water flow throughability, resulting in a reduction in the working efficiency of the circulation pump. Cleaning the flocs on the outer side of the filter screen requires a lot of time and manpower. Moreover, if the cleaning is not timely or thorough, it will exacerbate the degree of blockage of the filter screen, forming a vicious cycle. The impeller is the core component of the circulation pump and is responsible for converting power into the kinetic energy of the water flow. When particulate matters adhere to the outer side of the impeller, it will increase the load of the impeller, resulting in a decrease in the working efficiency of the circulation pump. The particulate matters also cause wear to the impeller. Cleaning the particulate matters on the outer side of the impeller requires disassembling the relevant components of the circulation pump, which is complex and time-consuming. Moreover, due to the blockage and pollution of the filter screen and the impeller, the quality of the water output by the circulation pump will deteriorate, and the content of impurities and pollutants in the water will increase, which will not only affect the treatment effect of the water treatment system but also cause damage to the subsequent equipment using water.

[0029] (3) Beneficial effects

[0030] The present invention has the following beneficial effects:

[0031] (1). For the water treatment circulating pump with convenient installation, the direction of the turbine rotation movement is the same, so that convection is generated in the water flow, thereby blowing the particulate matter adsorbed on the impeller, and then flowing out from the cleaning conduit along with the water flow. The convection effect will form eddy current or turbulence in the water flow, which helps to blow or wash down the particulate matter adsorbed on the impeller, making it easier for the particulate matter to fall off from the impeller, reducing the wear of the particulate matter on the impeller, cleaning the particulate matter on the impeller and improving the water flow quality output by the circulating pump. Particulate matter is one of the main reasons for the decline of water quality, so keeping the impeller clean is crucial for improving water quality.

[0032] (2) The circulation pump for water treatment with convenient installation changes the water flow direction, causing part of the water flow to flow out through the branch pipe, changing the water flow direction from a straight flow to a ninety-degree upward flow. This facilitates the removal of flocs on the first filter screen by the water flow direction. The water flow will generate a stronger scouring force on the first filter screen, and the scouring force helps to loosen and remove the flocs, impurities, etc. attached to the first filter screen, thereby improving the cleaning effect of the first filter screen. Changing the water flow direction can effectively reduce the risk of filter screen blockage, clean the filter screen by changing the water flow direction, and maintain the stable operation of the circulation pump.

[0033] (3) The circulation pump for water treatment with convenient installation has the function of sending the water quality analysis report to the remote control terminal through the water quality analysis unit and displaying it in the form of a report. The water quality analysis unit can monitor the water quality parameters in real time, summarize the data to generate a report, so as to timely detect potential water quality problems. The operation and maintenance personnel can adjust the operation parameters of the circulation pump, such as flow rate and pressure, to adapt to different water quality conditions, which helps to ensure that the circulation pump operates in the best state, improve the overall efficiency and stability of the system. The change of the U value in the water quality analysis report can reflect the type and degree of water source pollution, judge the type of water source pollution, and take corresponding treatment measures to improve the water treatment efficiency and water quality.

[0034] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Embodiment 1

[0044] Please refer to Figures 1 - 5 , the embodiments of the present invention provide a technical solution: a circulation pump for water treatment with convenient installation, including a circulation pump 1 and a water quality cleaning system. A pump casing 3 is installed on the circulation pump 1, an impeller 2 is installed inside the circulation pump 1, a diversion cavity 4 is opened inside the pump casing 3, a power assembly is installed on the outer surface of the pump casing 3, a first transmission assembly is installed on the outer surface of the power assembly, a second transmission assembly is installed on the outer surface of the power assembly, and a third transmission assembly is installed on the outer surface of the power assembly;

[0045] A sphere 14 is installed on the outer surface of the first transmission assembly, a liquid flow hole 15 is opened inside the sphere 14, a sealing plate 18 is installed on the outer surface of the second transmission assembly, a retaining ring 17 is installed on the outer surface of the sealing plate 18, a pipe plug 33 is installed on the outer surface of the third transmission assembly, a convection cleaning assembly is installed inside the pipe plug 33. The first transmission assembly and the third transmission assembly are used to conveniently clean the sundries inside the circulation pump 1, and the second transmission assembly facilitates the operation of the first transmission assembly and the third transmission assembly;

[0046] A cleaning conduit 23 is installed inside the pump housing 3. The convective cleaning assembly includes a micro motor 26 and a magnetic main shaft two 27. The micro motor 26 is installed on the outer surface of the cleaning conduit 23, and the magnetic main shaft two 27 is installed on the outer surface of the output end of the micro motor 26. A magnetic secondary shaft two 28 is movably installed inside the pipe plug 33. A turbine 29 is installed on one end surface of the magnetic secondary shaft two 28. A second filter screen 25 is installed on the inner surface of the pipe plug 33. One end surface of the magnetic secondary shaft two 28 is in movable contact with the inside of the second filter screen 25. The rotational movement directions of the turbines 29 are the same, but their installation positions are opposite, so that convection is generated in the water flow, thereby blowing the particulate matter adsorbed on the impeller 2, and then flowing out from the cleaning conduit 23 along with the water flow. The convective effect will form vortices or turbulence in the water flow, which helps to blow or wash off the particulate matter adsorbed on the impeller 2. Due to the power generated by the rotation of the turbines 29, the convection in the water flow will further enhance this washing effect, making it easier for the particulate matter to fall off from the impeller 2. By utilizing the convective effect, the particulate matter on the impeller 2 can be more effectively cleaned without an additional power source or chemical cleaning agent, which not only saves energy and cost, but also improves the cleaning efficiency, enabling the circulating pump 1 to return to the normal working state faster. Long-term attachment of particulate matter to the impeller 2 will cause wear and corrosion of the impeller 2, thereby affecting the performance and service life of the circulating pump 1. Cleaning by utilizing the convective effect can reduce the wear of the particulate matter on the impeller 2 and extend the service life of the equipment. Cleaning the particulate matter on the impeller 2 improves the water flow quality output by the circulating pump 1. Particulate matter is one of the main reasons for the decline in water quality, so keeping the impeller 2 clean is crucial for improving water quality.

[0047] The power assembly includes a stepper motor 7 and a magnetic main shaft one 8. The stepper motor 7 is installed on the inner surface of the pump housing 3, and the magnetic main shaft one 8 is installed on the outer surface of the output end of the stepper motor 7. A magnetic secondary shaft one 9 is movably installed inside the pump housing 3. The pump housing 3 is provided with a liquid inlet flange 5 and a liquid outlet flange 6. A gear ring 16 is installed on the outer surface of the magnetic secondary shaft one 9. A first filter screen 24 is installed at the inner wall of the liquid inlet flange 5. The control and cleaning unit controls the stepper motor 7 to work through a controller. The stepper motor 7 drives the magnetic main shaft one 8 to perform a rotational movement. There is an attractive force between the magnetic main shaft one 8 and the magnetic secondary shaft one 9. The magnetic main shaft one 8 drives the magnetic secondary shaft one 9 to perform a rotational movement. The magnetic secondary shaft one 9 stably drives the gear ring 16 to perform a rotational movement inside the pump housing 3. The outer surface of the gear ring 16 meshes with the outer surfaces of two gear racks 22.

[0048] The first transmission component includes a driving transmission wheel 10 and a valve rod 11. The driving transmission wheel 10 is installed on the outer surface of the magnetic secondary shaft two 28. The valve rod 11 is movably installed inside the pump housing 3. A driven transmission wheel 12 is installed on the outer surface of the valve rod 11. A belt 13 is jointly movably installed on the outer surfaces of the driven transmission wheel 12 and the driving transmission wheel 10. A branch pipe 31 is installed inside the pump housing 3. One end surface of the valve rod 11 extends into the branch pipe 31. One end surface of the valve rod 11 is fixedly connected to the outer surface of the sphere 14. The outer surface of the sphere 14 is in movable contact with the outer surface of the branch pipe 31. One end surface of the branch pipe 31 extends to the outside of the pump housing 3. And the magnetic secondary shaft two 28 synchronously drives the driving transmission wheel 10 to rotate. The driving transmission wheel 10 drives the driven transmission wheel 12 to rotate through the belt 13. The driven transmission wheel 12 drives the valve rod 11 to rotate. The valve rod 11 drives the sphere 14 to rotate. The sphere 14 drives the liquid flow hole 15 to be horizontal with the direction of the branch pipe 31, so as to change the water flow direction. Part of the water flow flows out through the branch pipe 31, changing the water flow direction, from a straight flow to a ninety-degree upward flow, so as to conveniently carry out the flocs on the first filter screen 24 through the water flow direction. The water flow will generate a stronger scouring force on the first filter screen 24. The scouring force helps to loosen and carry away the flocs, impurities, etc. attached to the first filter screen 24, thereby improving the cleaning effect of the first filter screen 24. Changing the water flow direction can effectively reduce the risk of filter screen blockage, because the accumulation of flocs and impurities on the filter screen is often one-way. Changing the water flow direction can break this accumulation mode and prevent the filter screen from failing due to long-term blockage. By changing the water flow direction to clean the filter screen, the stable operation of the circulating pump 1 is maintained.

[0049] The second transmission component includes two moving chambers 19 and a first slider 20. The two moving chambers 19 are opened inside the pump housing 3. The first slider 20 is movably installed at the inner wall of one of the moving chambers 19. A sealing plate 18 is installed on one end surface of the first slider 20. A retaining ring 17 is installed on one end surface of the sealing plate 18. The outer surface of the retaining ring 17 is in movable contact with the inner wall of the diversion chamber 4. The outer surface of the sealing plate 18 is in movable contact with the inner wall of one of the moving chambers 19. The first slider 20 drives the sealing plate 18 to move in the moving chamber 19. The sealing plate 18 drives the retaining ring 17 to seal the diversion chamber 4 and the liquid outlet flange 6.

[0050] The third transmission component includes a second slider 21 and a cleaning conduit 23. The cleaning conduit 23 is installed inside the pump housing 3, and one end surface of the cleaning conduit 23 extends to the outside of the pump housing 3. The second slider 21 is movably installed on the inner wall of another moving cavity 19. Gear racks 22 are installed on one end surfaces of both the second slider 21 and the first slider 20. The outer surfaces of the two gear racks 22 are meshed with the outer surface of the gear ring 16. Gate valves 32 are installed inside both the cleaning conduit 23 and the branch pipe 31. An extension cavity 30 is formed inside the cleaning conduit 23. The outer surface of the second slider 21 is in movable contact with the inner wall of the extension cavity 30. The outer surface of the pipe plug 33 is in movable contact with the inner wall of the extension cavity 30, and the outer surface of the pipe plug 33 is in movable contact with the inner wall of the cleaning conduit 23. The second slider 21 moves inside the another moving cavity 19 and the extension cavity 30, and the second slider 21 drives the pipe plug 33 to move on the inner wall of the cleaning conduit 23 and the inner wall of the extension cavity 30, so that the cleaning conduit 23 is penetrated.

[0051] The working process of the present invention: When the circulating pump 1 is conveniently installed at a fixed position by bolts, when the circulating pump 1 is working, when the flow rate data Q1 obtained by the flow sensor after the first filter 24 of the liquid inlet flange 5 is less than or equal to the flow rate threshold Qmin, or when the flow rate data Q2 obtained by the flow sensor after the liquid outlet flange 6 is less than or equal to the flow rate threshold Qmin', the control cleaning unit controls the stepper motor 7 to work through the controller. The stepper motor 7 drives the magnetic main shaft 8 to rotate. There is an attractive force between the magnetic main shaft 8 and the magnetic auxiliary shaft 9. The magnetic main shaft 8 drives the magnetic auxiliary shaft 9 to rotate. The magnetic auxiliary shaft 9 stably drives the gear ring 16 to rotate inside the pump housing 3. The outer surface of the gear ring 16 is meshed with the outer surfaces of the two gear racks 22. The two gear racks 22 correspondingly drive the first slider 20 and the second slider 21 to work. The first slider 20 and the second slider 21 move towards each other. The first slider 20 drives the sealing plate 18 to move inside the moving cavity 19. The sealing plate 18 drives the retaining ring 17 to seal the space between the diversion cavity 4 and the liquid outlet flange 6.

[0052] Moreover, the second slider 21 moves within another moving chamber 19 and the extension chamber 30. The second slider 21 drives the pipe plug 33 to move along the inner wall of the cleaning conduit 23 and the inner wall of the extension chamber 30, thereby unblocking the cleaning conduit 23. Meanwhile, the second magnetic secondary shaft 28 synchronously drives the driving sprocket 10 to rotate. The driving sprocket 10 drives the driven sprocket 12 to rotate via the belt 13. The driven sprocket 12 drives the valve stem 11 to rotate, the valve stem 11 drives the sphere 14 to rotate, and the sphere 14 rotates to align the liquid flow hole 15 horizontally with the branch pipe 31. The controller synchronously controls the operation of the two gate valves 32, and controls the operation of the micro motor 26 via the controller. The micro motor 26 drives the second magnetic main shaft 27 to rotate. There is an attractive force between the second magnetic main shaft 27 and the second magnetic secondary shaft. The second magnetic main shaft 27 drives the second magnetic secondary shaft 28 to rotate, and the second magnetic secondary shaft 28 drives the turbine 29 to rotate, thereby controlling the operation of the circulation pump 1, changing the water flow direction. Part of the water flows out through the branch pipe 31, changing the water flow direction from a straight flow to a ninety-degree upward flow, which facilitates the removal of the flocs on the first filter screen 24 by the water flow direction. The water flow will generate a stronger scouring force on the first filter screen 24, and the scouring force helps to loosen and remove the flocs, impurities, etc. attached to the first filter screen 24, thereby improving the cleaning effect of the first filter screen 24. Changing the water flow direction can effectively reduce the risk of filter screen blockage because the accumulation of flocs and impurities on the filter screen is often unidirectional. Changing the water flow direction can break this accumulation pattern and prevent the filter screen from failing due to long-term blockage. Cleaning the filter screen by changing the water flow direction can maintain the stable operation of the circulation pump 1.

[0053] Moreover, the two turbines 29 rotate in the same direction but are installed oppositely, thereby generating a convection in the water flow, which blows the particulate matter adsorbed on the impeller 2, and then the particulate matter flows out from the cleaning conduit 23 along with the water flow. The convection effect will form vortices or turbulence in the water flow, which helps to blow or scour off the particulate matter adsorbed on the impeller 2. Due to the power generated by the rotation of the turbine 29, the convection in the water flow will further enhance this scouring effect, making it easier for the particulate matter to fall off the impeller 2. By utilizing the convection effect, the particulate matter on the impeller 2 can be more effectively cleaned without the need for additional power sources or chemical cleaning agents, which not only saves energy and costs but also improves the cleaning efficiency, enabling the circulation pump 1 to return to its normal operating state more quickly. The long-term attachment of particulate matter to the impeller 2 will cause wear and corrosion of the impeller 2, thereby affecting the performance and lifespan of the circulation pump 1. Cleaning using the convection effect can reduce the wear of the impeller 2 by particulate matter and extend the service life of the equipment. Cleaning the particulate matter on the impeller 2 improves the water flow quality output by the circulation pump 1. Particulate matter is one of the main reasons for water quality degradation, so keeping the impeller 2 clean is crucial for improving water quality.

[0054] The turbine 29 rotates continuously to prevent particles from being adsorbed on the second filter screen 25. The continuous rotation of the turbine 29 produces a dynamic flushing effect in the water flow. The flushing effect can continuously disturb the water flow, making it difficult for particles to stably adhere to the second filter screen 25. Even if some particles temporarily stay on the filter screen, they will be quickly carried away by the flushing of the water flow. Particles are more likely to settle and adhere in still or slowly flowing water, and the rotation of the turbine 29 can accelerate the water flow, reduce the chance of particle deposition, and greatly reduce the amount of particle accumulation on the second filter screen 25. Example 2

[0057] The flow analysis unit obtains and processes the flow data Q1 and the flow data Q2, obtains a flow threshold Qmin preset for the flow data Q1 and a flow threshold Q′min preset for the flow data Q2, and then judges the flow data Q1 and the flow data Q2 to generate an automatic cleaning signal and sends it to the control cleaning unit;
