Description

Technical Field

[0001] The present invention relates to the technical field of circulation pumps, and specifically 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 to make 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] During the use of the existing circulation pump for water treatment, there are flocs, 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 will 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 equipment using the water subsequently.

[0016] (III) Beneficial effects

[0017] The present invention has the following beneficial effects: 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 impeller by the particulate matter, cleaning the particulate matter on the impeller to improve the water quality of the water flow 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.

[0018] For the water treatment circulating pump with convenient installation, by changing the water flow direction, part of the water flow flows out through the branch pipe, changing the water flow direction, from linear flow to upward flow at 90 degrees, so as to conveniently carry out the flocs on the filter screen one through the water flow direction. The water flow will generate a stronger scouring force on the filter screen one, and the scouring force helps to loosen and carry away the flocs, impurities, etc. attached to the filter screen one, thereby improving the cleaning effect of the filter screen one. Changing the water flow direction can effectively reduce the risk of filter screen blockage, and changing the water flow direction to clean the filter screen to maintain the stable operation of the circulating pump.

[0019] The circulation pump for water treatment with convenient installation can send the water quality analysis report to the remote control terminal through the water quality analysis unit and display it in the form of a report. The water quality analysis unit can monitor water quality parameters in real time, summarize the data to generate a report, so as to timely discover 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.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] 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.

[0024] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. Embodiment 1

[0025] Please refer to Figures 1 - 5 , the embodiments of the present invention provide a technical solution: a circulation pump for water treatment that is conveniently installed, 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; 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 for conveniently cleaning 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; Inside the pump housing 3, a cleaning conduit 23 is installed. 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. Inside the pipe plug 33, a magnetic secondary shaft two 28 is movably installed. On one end surface of the magnetic secondary shaft two 28, a turbine 29 is installed. On the inner surface of the pipe plug 33, a second filter screen 25 is installed. 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 down 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 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 cleaned more effectively without the need for 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. The long-term attachment of particulate matter on 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 using 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 deterioration of water quality, so keeping the impeller 2 clean is crucial for improving water quality.

[0026] 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. Inside the pump housing 3, a magnetic secondary shaft one 9 is movably installed. The pump housing 3 is provided with an inlet flange 5 and an 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 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 rotate inside the pump housing 3. The outer surface of the gear ring 16 meshes with the outer surfaces of two gear racks 22.

[0027] The first transmission assembly 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 movably installed on the outer surfaces of both 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, thereby changing 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 pattern 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 circulation pump 1 is maintained.

[0028] The second transmission assembly 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 inside 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.

[0029] 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. 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. The second slider 21 drives the pipe plug 33 to move along the inner walls of the cleaning conduit 23 and the extension cavity 30, so as to make the cleaning conduit 23 unblocked.

[0030] 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 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 threshold Qmin, or when the flow data Q2 obtained by the flow sensor after the liquid outlet flange 6 is less than or equal to the flow threshold Qmin', the cleaning unit is controlled to work by the controller to control the stepping motor 7. The stepping motor 7 drives the first magnetic spindle 8 to rotate. There is an attractive force between the first magnetic spindle 8 and the first magnetic secondary shaft 9. The first magnetic spindle 8 drives the first magnetic secondary shaft 9 to rotate. The first magnetic secondary 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 gap between the diversion cavity 4 and the liquid outlet flange 6.

[0031] Moreover, the second slider 21 moves within the other 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 enabling the cleaning conduit 23 to be unblocked. Meanwhile, the second magnetic auxiliary shaft 28 synchronously drives the main drive wheel 10 to rotate. The main drive wheel 10 drives the driven drive wheel 12 to rotate via the belt 13. The driven drive wheel 12 drives the valve stem 11 to rotate. The valve stem 11 drives the sphere 14 to rotate. The sphere 14 drives the liquid flow hole 15 to be horizontal with respect to the direction of the branch pipe 31. The controller synchronously controls the operation of the two gate valves 32. The controller controls the operation of the micro motor 26. 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 auxiliary shaft. The second magnetic main shaft 27 drives the second magnetic auxiliary shaft 28 to rotate. The second magnetic auxiliary shaft 28 drives the turbine 29 to rotate, controlling the operation of the circulation pump 1, thereby 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. This 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. 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. Since 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. By changing the water flow direction to clean the filter screen, the stable operation of the circulation pump 1 is maintained.

[0032] Moreover, the turbine 29 rotates in the same direction but is installed in a relative position, thereby generating a convection in the water flow. This convection 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 eddies 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 an additional power source or chemical cleaning agent. This not only saves energy and cost but also improves the cleaning efficiency, enabling the circulation pump 1 to return to the normal working 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 service life 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 the deterioration of water quality. Therefore, keeping the impeller 2 clean is crucial for improving water quality.

[0033] Moreover, the turbine 29 rotates continuously, preventing particulate matter from adhering to the second filter screen 25. The continuous rotation of the turbine 29 generates a dynamic scouring effect in the water flow. This scouring effect can continuously disturb the water flow, making it difficult for particulate matter to stably adhere to the second filter screen 25. Even if some particulate matter temporarily stays on the filter screen, it will be quickly carried away due to the scouring of the water flow. Particulate matter is more likely to deposit and adhere in static or slow-flowing water, while the rotation of the turbine 29 can accelerate the water flow and reduce the deposition chance of particulate matter. The accumulation amount of particulate matter on the second filter screen 25 will be greatly reduced. Embodiment 2

[0034] As Figure 6 shown, a circulation pump for water treatment with convenient installation, a circulation pump 1 and a water quality cleaning system. The water quality cleaning system includes a data acquisition unit, a flow analysis unit, a control cleaning unit, and a water quality analysis unit; The data acquisition unit acquires the flow data Q1 after passing through the first filter screen 24 and the flow data Q2 after passing through the liquid outlet flange 6 through a flow sensor, and sends the flow data Q1 and the flow data Q2 to the flow analysis unit; The flow analysis unit acquires the flow data Q1 and the flow data Q2 and processes them to obtain a preset flow threshold Qmin for the flow data Q1 and a preset flow threshold Q'min for the flow data Q2. Then, it judges the flow data Q1 and the flow data Q2 to generate an automatic cleaning signal and sends it to the control cleaning unit; The control cleaning unit is used to acquire the automatic cleaning signal and control the stepper motor 7 and the gate valve 32 to work, so as to open the branch pipe 31 and the cleaning conduit 23 to clean the flocs wound on the first filter screen 24 and the particulate matter attached to the impeller 2; The water quality analysis unit is used to acquire the generation time and source of the automatic cleaning signal. Within a preset analysis period T, it analyzes the generation frequency of the automatic cleaning signal, and then generates a water quality report of the water source treated by the water treatment circulation pump 1; The specific process of generating the automatic cleaning signal: If the flow data Q1 is less than or equal to the flow threshold Qmin, an automatic cleaning signal F1 is generated; If the flow data Q2 is less than or equal to the flow threshold 'Qmin, an automatic cleaning signal F2 is generated.

[0035] The specific process of generating the water quality report of the water source treated by the water treatment circulation pump 1 is as follows: S101. Within a preset analysis period T, acquire the generation frequency f1 of the automatic cleaning signal F1 and the generation frequency f2 of the automatic cleaning signal F2; S102. Calculate the frequency analysis coefficient U according to the following formula: , is a preset dimensionless coefficient; S103. If U is greater than or equal to 0, the water quality report indicates that the content of flocs in the water source treated by the circulating pump 1 for water treatment is greater than the content of particulate matter; S104. If U is less than 0, the water quality report indicates that the content of flocs in the water source treated by the circulating pump 1 for water treatment is less than the content of particulate matter.

[0036] The water quality analysis unit sends the water quality analysis report to the remote control terminal and displays it in the form of a report to help the operation and maintenance personnel summarize the water quality change rules and optimize the operation parameters of the circulating pump 1 such as flow rate, pressure and maintenance period. Long-term monitoring of the change of the U value can judge the type of water source pollution. For example, when there are many particulate matters in industrial wastewater, it provides a basis for improving the water treatment process.

[0037] With the function that the water quality analysis unit of the present invention sends the water quality analysis report to the remote control terminal and displays it in the form of a report, the water quality analysis unit can monitor the water quality parameters in real time and summarize the data to generate a report. By viewing these reports, the operation and maintenance personnel can clearly understand the change trends and rules of the water quality parameters, so as to timely discover potential water quality problems. The operation and maintenance personnel can adjust the operation parameters of the circulating pump 1, such as flow rate and pressure, to adapt to different water quality conditions, which helps to ensure that the circulating pump 1 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.
