Abstract

The utility model relates to a cleaning device of a water treatment system, including a water tank, a cleaning pump and an arc-shaped connection component. The water tank is provided with a water outlet, and the cleaning pump is provided with a water inlet. One end of the arc-shaped connection component is connected to the water outlet, and the other end is connected to the water inlet. The position of the water inlet is lower than the water outlet in the vertical direction, so that when the liquid in the water tank is emptied, a water seal is formed in the arc-shaped connection component. Since the position of the water inlet is lower than the water outlet in the vertical direction, when the liquid in the water tank is emptied, the liquid in the arc-shaped connection component cannot flow back to the water tank, and a water seal is formed. The formation of this water seal prevents air from entering the cleaning pump, avoids the waterless operation of the cleaning pump, reduces the risk of damage to the cleaning pump, and extends the service life of the equipment.

Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a cleaning device of a water treatment system and a water treatment system. Background Art

[0002] In modern water treatment systems, ultrafiltration devices (UF) and reverse osmosis devices (RO) are widely used to produce pure water or drinking water. After these devices have been running for a period of time, the membrane components will be blocked by scaling of calcium and magnesium ions in the water or contaminated by microorganisms, thus affecting their performance. Therefore, it is necessary to chemically clean the membrane components regularly.

[0003] At present, chemical cleaning usually uses two or more cleaning liquids for cyclic cleaning. In actual operation, after the water tank is cleaned with the first cleaning liquid, it is drained and then water is added to prepare the second cleaning liquid. Each time the cleaning liquid is drained, the water in the cleaning pump will flow back to the water tank along the water inlet pipe, causing the water inlet pipe to be filled with air. When water is added again to prepare the cleaning liquid, part of the air is trapped in the cleaning pump. When the cleaning pump is started, due to the presence of air, an air chamber is formed in the pump and the pressure cannot be effectively transmitted, which hinders the continuous flow of liquid, resulting in the cleaning pump being unable to operate normally, unable to pump water, and insufficient pressure. At this time, the exhaust port of the cleaning pump must be manually opened to discharge the gas in the pump so that the cleaning pump can work normally.

[0004] However, in actual operation, if the air is not found and discharged in time, the cleaning pump will run without water for a long time, causing damage to the mechanical seal of the pump, or even causing the pump body to overheat and damage the pump body. This not only increases the maintenance cost of the equipment, but may also cause production interruptions and affect production efficiency.

[0005] Therefore, it is necessary to propose a cleaning device for a water treatment system to solve the problem of waterless operation of a cleaning pump caused by air entering during the process of replacing the cleaning liquid. Utility Model Content

[0006] The embodiment of the utility model provides a cleaning device for a water treatment system to solve the problem of a cleaning pump running without water due to air entering during the process of replacing cleaning liquid.

[0011] The water inlet is located lower than the water outlet in the vertical direction, so that when the liquid in the water tank is emptied, a water seal is formed in the arc-shaped connecting component.

[0012] In one embodiment, the arc-shaped connecting assembly includes a water inlet pipe and an elbow, one end of the water inlet pipe is connected to the cleaning pump, and the other end is connected to the elbow, and the end of the elbow away from the water inlet pipe is connected to the water outlet.

[0013] In one embodiment, the angle of the elbow is set to A, satisfying the following relationship: 45°≤A≤90°.

[0014] In one embodiment, the elbow includes a first elbow and a second elbow, both ends of the first elbow are respectively connected to the water inlet pipe, and one end of the second elbow is connected to the water inlet pipe, and the other end is connected to the water outlet.

[0015] In one embodiment, the outer diameter of the elbow is set to D1, and the outer diameter of the water inlet pipe is set to D2, satisfying the following relationship: D1>D2.

[0016] In one embodiment, the outer diameter of the water outlet is set to D3, satisfying the following relationship: D1>D3.

[0017] In one embodiment, the water tank is provided with a drainage portion for draining the liquid in the water tank.

[0018] In one embodiment, the drainage part includes a drainage pipe and a drainage valve, the drainage pipe is communicated with the water tank, the drainage valve is connected to the drainage pipe, and the drainage valve is used to control the flow and stop of the liquid.

[0019] In one embodiment, the cleaning pump is provided with an exhaust port for exhausting gas in the cleaning pump.

[0020] The utility model also comprises a water treatment system, comprising the cleaning device of the water treatment system as described above.

[0021] The above-mentioned cleaning device for a water treatment system has at least the following beneficial effects:

[0022] Since the cleaning device of the water treatment system includes a water tank, a cleaning pump and an arc-shaped connection component, the water tank is provided with a water outlet, and the cleaning pump is provided with a water inlet; one end of the arc-shaped connection component is connected to the water outlet, and the other end is connected to the water inlet. Among them, the position of the water inlet is lower than the water outlet in the vertical direction, so that when the liquid in the water tank is emptied, a water seal is formed at the water outlet. Since the position of the water inlet is lower than the water outlet in the vertical direction, when the liquid in the water tank is emptied, the liquid in the arc-shaped connection component cannot flow back to the water tank and form a water seal. The formation of this water seal prevents air from entering the arc-shaped connection component and then entering the cleaning pump, avoiding the waterless operation of the cleaning pump, reducing the risk of damage to the cleaning pump, and extending the service life of the equipment. The cleaning pump can start and run automatically, without manual intervention to discharge the air of the cleaning pump, making the operation of the cleaning system more convenient and automated. Due to the automated operation of the cleaning system, the need for manual operation is reduced, saving labor costs and time costs. The stable operation of the cleaning pump and the formation of the water seal ensure that the cleaning liquid fully enters the treatment system, achieving an efficient cleaning effect and improving the cleaning efficiency of the system.

The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] refer to Figures 1 to 4 , a cleaning device 10 for a water treatment system, comprising:

[0034] The water tank 11 is provided with a water outlet 111a;

[0035] The cleaning pump 12 is provided with a water inlet 121a; and

[0036] The arc-shaped connecting component 13 has one end connected to the water outlet 111a and the other end connected to the water inlet 121a;

[0037] The position of the water inlet 121a is lower than the water outlet 111a in the vertical direction, so that when the liquid in the water tank 11 is emptied, a water seal is formed in the arc-shaped connecting component 13.

[0038] Since the position of the water inlet 121a is lower than the water outlet 111a in the vertical direction, when the liquid in the water tank 11 is emptied, the liquid in the arc-shaped connecting component 13 cannot flow back into the water tank 11 and a water seal is formed. Specifically, when the liquid in the water tank 11 is emptied, a water column will exist in the arc-shaped connecting component 13. Due to the height difference between the water inlet 121a and the water outlet 111a, the water in the bottom inflection point of the arc-shaped connecting component 13 cannot overcome gravity and flow back into the water tank 11, thereby forming a water seal. The formation of this water seal can prevent air from entering the cleaning pump 12, avoid the waterless operation of the cleaning pump 12, reduce the risk of damage to the cleaning pump 12, and extend the service life of the equipment. The cleaning pump 12 can be automatically started and operated without manual intervention to discharge the air in the cleaning pump 12, making the operation of the cleaning system more convenient and automated. Due to the automated operation of the cleaning system, the need for manual operation is reduced, saving labor costs and time costs. The stable operation of the cleaning pump 1 2 and the formation of the water seal ensure that the cleaning liquid fully enters the treatment system, achieves an efficient cleaning effect, and improves the cleaning efficiency of the system.

[0039] It should be noted that the arc-shaped connection component 13 can be a curved pipe, an elbow 132, or a combination of a curved pipe and an elbow 132. When the arc-shaped connection component 13 is a curved pipe, one end of the curved pipe is connected to the water outlet 111a of the water tank 11, and the other end is connected to the water inlet 121a of the cleaning pump 12. The angle and bending degree of the curved pipe can be adjusted according to specific system requirements and design parameters to ensure the formation and stability of the water seal.

[0040] When the arc-shaped connection component 13 is a combination of an elbow and an elbow 132, it can adapt to more system layouts and requirements. The elbow portion ensures the continuity and smoothness of the water flow, while the elbow 132 portion helps change the direction of the water flow and ensures the formation of a water seal.

[0041] Specifically, refer to Figure 3 In an embodiment of the present utility model, the arc connection component 13 includes an inlet pipe 131 and an elbow 132, one end of the inlet pipe 131 is connected to the cleaning pump 12, and the other end is connected to the elbow 132, and the end of the elbow 132 away from the inlet pipe 131 is connected to the water outlet 111a.

[0042] In this embodiment, the position of the water inlet 121a is lower than the water outlet 111a in the vertical direction. Due to the arrangement of the water inlet pipe 131 and the elbow 132, when the liquid in the water tank 11 is drained, the liquid will stagnate at the elbow 132 when passing through the elbow 132, forming a water seal. The water seal prevents air from entering the water inlet pipe 131 and then entering the cleaning pump 12, thereby avoiding the situation where the cleaning pump 12 runs without water, and improving the reliability and stability of the cleaning system.

[0043] Specifically, in the present embodiment, the angle of the elbow 132 is set to A, satisfying the following relationship: 45°≤A≤90°. By setting the angle of the elbow 132 between 45° and 90°, it can be ensured that when the liquid is drained, a stable water seal is formed at the elbow to prevent air from entering the cleaning pump 12. Secondly, the angle range of 45° to 90° makes the water flow in the elbow slow, increases the stability of the water column, and thus enhances the effect of the water seal. The stability of the water seal is directly related to the normal operation of the cleaning pump 12. The present embodiment adopts a 45-degree elbow 132. The appropriate angle of the elbow 132 can not only meet the requirements of the water flow, but also make the entire system structure more compact, save space, and is also easier to install and maintain.

[0044] When the angle of the elbow 132 is too large, the resistance of the water flow through the elbow 132 will increase, causing the speed of the water flow to slow down, which may reduce the pumping efficiency of the cleaning pump 12 and affect the operating efficiency of the system. Secondly, the excessively large angle of the elbow 132 may cause the water flow to be unable to form an effective water seal at the elbow 132, thereby increasing the risk of water backflow and reducing the stability of the cleaning system. Moreover, the excessively large angle of the elbow 132 will cause the size of the elbow 132 to increase, occupying more installation space, which may be detrimental to the compactness and installation convenience of the system.

[0045] When the angle of the elbow 132 is too small, the water flow will bend more when passing through the elbow 132, increasing the resistance of the water flow, which may cause the water flow speed to be unstable, or even generate vortices, affecting the smoothness of the water flow. Secondly, a too small angle of the elbow 132 may cause the water flow to be unable to form an effective water seal at the elbow 132, increasing the risk of water backflow and reducing the stability of the cleaning system. Moreover, a too small angle of the elbow 132 will cause the water flow to be subjected to greater friction when passing through the elbow 132, which may easily cause wear and damage to the pipeline and affect the service life of the system.

[0046] Specifically, the elbow 132 includes a first elbow 1311 and a second elbow 1312, both ends of the first elbow 1311 are respectively connected to the water inlet pipe 131, one end of the second elbow 1312 is connected to the water inlet pipe 131, and the other end is connected to the water outlet 111a.

[0047] In this embodiment, the first elbow 1311 and the second elbow 1312 are both 4-5 degree elbows, and there may be two water inlet pipes 131, which are respectively recorded as the first water inlet pipe (not marked) and the second water inlet pipe (not marked). The first water inlet pipe is connected to the elbow 132 and the water inlet 121a, and the second water inlet pipe is connected to the first elbow 1311 and the second elbow 1312. When the water tank 11 is emptied, the water seal formed at the first elbow 1311 effectively prevents air from entering the cleaning pump 12, thereby ensuring the normal operation of the cleaning pump 12. Specifically, due to the existence of the water seal, when the water tank 11 is filled with cleaning liquid again, a small amount of air in the second elbow 1312 near the water outlet 111a will be discharged, and the cleaning liquid in the water tank 11 will flow into the cleaning pump 12 through the second elbow 1312, the second water inlet pipe, the first elbow 1311, and the first water inlet pipe in sequence, thereby preventing the cleaning pump 12 from running without water. Secondly, the design of the first elbow 1311 and the second elbow 1312 allows the water flow to undergo two changes in direction during the connection process, which helps to reduce the resistance of the water flow through the elbow 132, ensures the smoothness and stability of the water flow, and improves the working efficiency of the cleaning system.

[0048] Specifically, refer to Figure 4 , the outer diameter of the elbow 132 is set to D1, the outer diameter of the water inlet pipe 131 is set to D2, and the outer diameter of the water outlet 111a is set to D3, satisfying the following relationship: D1>D2, D1>D3.

[0049] Since the outer diameter of the elbow 132 is larger than the outer diameter of the water inlet pipe 131, the elbow 132 is sleeved on the water inlet pipe 131, and the water flow will experience a transition from a larger diameter to a smaller diameter when passing through the elbow 132. Such a transition is smoother, which helps to reduce the resistance of the water flow and improve the operating efficiency of the system. The larger outer diameter of the elbow 132 helps to form a more stable water seal. When the water tank 11 is emptied, the water seal formed at the elbow 132 is more reliable, effectively preventing air from entering the cleaning pump 12, and ensuring the normal operation of the cleaning pump 12. Since water has a certain inertia when flowing, when the water flows through the elbow 132 with a larger outer diameter, the speed of the water flow will be subject to certain restrictions, which makes it easier for the water flow to form a stable water seal. In contrast, if the outer diameter of the elbow 132 is smaller, the water flow will pass through at a higher speed, and the stability of the water seal formation may be reduced. The elbow 132 with a larger outer diameter will guide the water flow to turn from the water outlet 111a to the water inlet 121a more smoothly, and the stability of the water flow direction will help form a more stable water seal. If the outer diameter of the elbow 132 is smaller, the change in the direction of the water flow may be more sudden, which may easily damage the water seal and cause water backflow. Secondly, the larger outer diameter of the elbow 132 usually means a larger cross-sectional area and stronger structural strength compared to the smaller outer diameter of the water inlet pipe 131, which helps to improve the pressure resistance and service life of the elbow 132.

[0050] In this embodiment, a water outlet pipe is provided at the water outlet 111a, the outer diameter of the water outlet 111a is the outer diameter of the water outlet pipe, and the elbow 132 is sleeved on the water outlet pipe. The smaller diameter of the water outlet 111a will increase the resistance of water flow compared to the larger outer diameter of the elbow 132, which helps to reduce the flow rate of the water flow and ensure the formation of a water seal. At the same time, the smaller diameter of the water outlet 111a is also conducive to maintaining the stability of the water flow, reducing the turbulence and vortex of the water flow, thereby reducing the resistance of the water flow and improving the operating efficiency of the cleaning system.

[0051] In some embodiments, the water tank 11 is provided with a drain portion 112 for draining the liquid in the water tank 11.

[0052] Specifically, in some embodiments, the drainage portion 112 includes a drainage pipe 1121 and a drainage valve 1122, the drainage pipe 1121 is communicated with the water tank 11, the drainage valve 1122 is connected to the drainage pipe 1121, and the drainage valve 1122 is used to control the flow and stop of the liquid.

[0053] The setting of the drainage part 112 can effectively drain the liquid in the water tank 11, avoiding the problem of liquid being retained in the water tank 11. In particular, when the cleaning device stops running or the cleaning liquid is replaced, the liquid in the water tank 11 is drained through the drainage part 112, which helps to reduce the impact of residual liquid on the equipment and water quality. The existence of the drainage part 112 makes the maintenance of the cleaning device more convenient. When the water tank 11 needs to be cleaned or maintained, the liquid in the water tank 11 can be drained through the drainage part 112, which is convenient for cleaning, maintenance or replacement of parts, ensuring the normal operation of the cleaning device.

[0054] The setting of the drain valve 1122 makes the drainage operation more flexible, and the flow and stop of the liquid can be controlled as needed. Such a design facilitates the emptying operation of the liquid in the water tank 11, making the use of the cleaning device more convenient and efficient. Secondly, the setting of the drain valve 1122 can flexibly control the flow direction of the liquid, and the liquid can be discharged into a designated drainage pipe or container, which facilitates the processing and disposal of the liquid and improves the operational flexibility of the cleaning system.

[0055] In some embodiments, the cleaning pump 12 is provided with an exhaust port (not shown) for exhausting the gas in the cleaning pump 12 .

[0056] The exhaust port can effectively remove the gas in the cleaning pump 12 to prevent the gas from accumulating in the pump to form an air chamber. The air chamber may cause the pumping efficiency of the pump to decrease, or even cause abnormal operation or failure of the pump. Therefore, the setting of the exhaust port helps to reduce the risk of the air chamber and ensure the normal operation of the cleaning pump 12. The gas in the cleaning pump 12 will affect the flow of water and the pumping efficiency of the pump. Expelling the gas through the exhaust port can reduce the situation where the water flow is obstructed by the gas, keep the water flow unobstructed, and improve the pumping efficiency of the cleaning pump 12. The gas accumulated in the cleaning pump 12 may cause problems such as overheating of the pump and increased vibration, thereby shortening the service life of the equipment. Timely exhausting the gas through the exhaust port can reduce the occurrence of these problems and extend the service life of the cleaning pump 12 and related equipment. The exhaust port can also be switched on and off through manual intervention to ensure the stability of the cleaning pump 12.

[0057] The utility model also includes a water treatment system, including the cleaning device 10 of the water treatment system as described above.

[0058] Among them, the cleaning device can effectively clean the membrane components or other key components in the water treatment system to ensure long-term stable operation of the system. The water treatment system as a whole contains a variety of different components and parts. The cleaning device can fully clean these parts to ensure the overall performance and water quality of the system. Secondly, the design of the cleaning device enables the water treatment system to realize automated cleaning operations, reducing the need for manual intervention and improving the operating efficiency and stability of the system. The system runs more reliably, does not require frequent manual operations, and saves manpower and time costs.

[0059] In summary, the water treatment system includes the above-mentioned water treatment system cleaning device 10. This design helps to achieve beneficial effects such as comprehensive cleaning, automatic operation and improved system stability, and provides a guarantee for the effective operation and maintenance of the water treatment system.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
