Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling tower equipment, and particularly relates to an adjustable self-cleaning water pump for a cooling tower. Background Technique
[0002] Cooling towers are widely used in industrial and commercial applications for heat dissipation and temperature control, and their stable operation directly affects the efficiency and reliability of the entire system. The self-cleaning water pump used in the cooling tower can effectively prevent the accumulation of dirt and impurities through its unique self-cleaning function, thereby improving the operation efficiency of the cooling system. However, there are still some deficiencies in the actual use of existing self-cleaning water pumps, especially in the continuity and reliability of the filtration system.
[0003] Traditional self-cleaning water pumps usually use a single filter cartridge for water quality filtration. When the filter cartridge is full of dirt or the filter screen is damaged, the entire system needs to be shut down for cleaning or the filter screen needs to be replaced, which not only affects the normal operation of the cooling tower, but also increases the maintenance cost and operation complexity. In addition, the design of a single filter cartridge often fails to meet the stable filtration requirements when facing high-pollution water quality or long-term continuous operation, resulting in a decrease in the system operation efficiency. Content of the Utility Model
[0004] The purpose of the utility model is to provide an adjustable self-cleaning water pump for a cooling tower to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable self-cleaning water pump for a cooling tower, including a bottom plate, a clean water tank and a sewage tank. A first filter cartridge is provided at the front end of the top surface of the bottom plate. One external end of the first filter cartridge is connected to one side of a second reversing valve through a third pipeline, and the other external end of the first filter cartridge is connected to one side of a third reversing valve through a fourth pipeline. A second filter cartridge is provided in the middle of the top surface of the bottom plate. One external end of the second filter cartridge is connected to the other side of the second reversing valve through a ninth pipeline, and the other external end of the second filter cartridge is connected to the other side of the third reversing valve through a tenth pipeline.
[0006] When using an adjustable self-cleaning water pump in this technical solution, the staff need to externally power the present utility model first and control the operation of the present utility model through the control panel. The staff open the pump body, and the pump body starts to operate and pumps water into the interior of the second pipeline through the first pipeline. Through the second pipeline, the water is transmitted to the interior of the third pipeline. Through the third pipeline, the water is transmitted to the interior of the first filter cartridge. After being filtered by the first filter cartridge, it is transmitted to the interior of the fourth pipeline. Through the fourth pipeline, it is transmitted to the interior of the fifth pipeline. The water is transmitted to the interior of the sixth pipeline by the fifth pipeline. Through the sixth pipeline, the water is transmitted to the interior of the pump body. Finally, the pump body conveys the water to the interior of the clean water tank for temporary storage through the seventh pipeline. When water is needed for the cooling tower, the staff control the fourth reversing valve to switch the passage, close the passage between the sixth pipeline and the fifth pipeline, and open the passage between the sixth pipeline and the eighth pipeline. After opening, control the pump body to run in reverse. In this way, the pump body will pump the water in the clean water tank into it through the seventh pipeline, and then transmit it to the interior of the eighth pipeline through the sixth pipeline and the fourth reversing valve. Finally, it is transmitted to the cooling tower through the eighth pipeline for use. When the first filter cartridge is filled with dirt or the internal filter screen is damaged, the staff control the fourth reversing valve to close the passage between the sixth pipeline and the eighth pipeline and open the passage between the sixth pipeline and the fifth pipeline. After the switching is completed, the staff control the second reversing valve and the third reversing valve to switch the passage. The second reversing valve closes the passage between the second pipeline and the third pipeline and opens the passage between the second pipeline and the ninth pipeline. The third reversing valve closes the passage between the fifth pipeline and the fourth pipeline and opens the passage between the fifth pipeline and the tenth pipeline. In this way, the water transmitted from the first pipeline will directly be transmitted to the interior of the ninth pipeline through the second pipeline, and then transmitted to the second filter cartridge through the ninth pipeline for filtration. The filtered water is transmitted to the interior of the fifth pipeline through the tenth pipeline, and finally transmitted to the interior of the clean water tank through the sixth pipeline, the pump body and the seventh pipeline. When the staff need to backwash the first filter cartridge and the second filter cartridge, the staff control the first reversing valve to close the passage between the second pipeline and the first pipeline and open the passage between the second pipeline and the eleventh pipeline. In this way, the first filter cartridge and the second filter cartridge are backwashed by pumping the water in the clean water tank. The sewage in the first filter cartridge and the second filter cartridge will be transmitted to the interior of the sewage tank through the second pipeline and the eleventh pipeline for temporary storage. When there is too much sewage, the staff can open the solenoid valve and drain it through the twelfth pipeline.
[0007] Preferably, one end of the second reversing valve is connected to one end of the first reversing valve through the second pipeline, and the other end of the first reversing valve is connected to the first pipeline. By setting the second reversing valve, the passage between the second pipeline and the third pipeline and the passage between the second pipeline and the ninth pipeline can be switched, achieving the effect of switching the liquid flow direction.
[0008] Preferably, one side of the first reversing valve is connected to the inner top end of the sewage tank through an eleventh pipeline, and the sewage tank is fixed at one end of the rear end of the top surface of the bottom plate. By setting the first reversing valve, the passage between the first pipeline and the second pipeline and the passage between the second pipeline and the eleventh pipeline can be switched, achieving the effect of switching the liquid flow direction.
[0009] Preferably, the inner bottom end of the sewage tank is connected with a twelfth pipeline, and one end of the twelfth pipeline is fixed with a solenoid valve. The setting of the sewage tank enables the sewage generated during the backwashing of the first filter cartridge and the second filter cartridge to be temporarily stored therein, facilitating unified treatment in the later stage. Through the cooperation of the solenoid valve and the twelfth pipeline, the sewage in the sewage tank can be discharged through this place, achieving the effect of switching on and off the sewage discharge.
[0010] Preferably, one end of the third reversing valve is connected to one end of the fourth reversing valve through a fifth pipeline, and the other end of the fourth reversing valve is connected with an eighth pipeline. By setting the third reversing valve, the passage between the fifth pipeline and the fourth pipeline and the passage between the fifth pipeline and the tenth pipeline can be switched, achieving the effect of switching the liquid flow direction.
[0011] Preferably, one side of the fourth reversing valve is connected to one end interface of the pump body through a sixth pipeline, and the pump body is fixed on the top surface of the bottom plate. By setting the fourth reversing valve, the passage between the eighth pipeline and the fifth pipeline and the passage between the fifth pipeline and the sixth pipeline can be switched, achieving the effect of switching the liquid flow direction.
[0012] Preferably, the other end interface of the pump body is connected to the inner bottom end of the water purification tank through a seventh pipeline, and the water purification tank is fixed at one end of the rear end of the top surface of the bottom plate. By setting the pump body, water can be pumped into the water purification tank and the sewage generated by backwashing is sent into the sewage tank, achieving the effects of active pumping and discharging.
[0013] Preferably, covers are rotatably installed at the outer top ends of the sewage tank and the water purification tank. The setting of the covers enables the inside of the water purification tank and the sewage tank to be opened, facilitating operations such as cleaning the inside by the staff.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. The present utility model is provided with multiple groups of pipelines and multiple reversing valves. Through the combination of the pipelines and the reversing valves, the two filter cartridges are switched for use, and a water purification tank and a sewage tank are provided to temporarily store purified water and sewage, enabling the system to maintain efficient filtration and automatic cleaning in the face of complex water quality and long-term operation, reducing the maintenance cost and extending the service life of the equipment.

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1
[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an adjustable self-cleaning water pump for a cooling tower proposed by the present utility model includes a bottom plate 1, a water purification tank 16 and a sewage tank 22. A first filter cartridge 7 is provided at the front end of the top surface of the bottom plate 1. One external end of the first filter cartridge 7 is connected to one side of the second reversing valve 5 through a third pipeline 6, and the other external end of the first filter cartridge 7 is connected to one side of the third reversing valve 9 through a fourth pipeline 8. A second filter cartridge 18 is provided in the middle of the top surface of the bottom plate 1. One external end of the second filter cartridge 18 is connected to the other side of the second reversing valve 5 through a ninth pipeline 19, and the other external end of the second filter cartridge 18 is connected to the other side of the third reversing valve 9 through a tenth pipeline 17.
[0024] The staff needs to externally power the present utility model first and control the operation of the present utility model through the control panel. The staff turns on the pump body 14, and the pump body 14 starts to operate and pumps water into the interior of the second pipeline 4 through the first pipeline 2. Through the second pipeline 4, the water is transmitted into the interior of the third pipeline 6. Through the third pipeline 6, the water is transmitted into the interior of the first filter cartridge 7. After being filtered by the first filter cartridge 7, it is transmitted into the interior of the fourth pipeline 8. Through the fourth pipeline 8, it is transmitted into the interior of the fifth pipeline 10. The fifth pipeline 10 transmits the water into the interior of the sixth pipeline 13. Through the sixth pipeline 13, the water is transmitted into the interior of the pump body 14. Finally, the pump body 14 conveys the water into the interior of the clean water tank 16 through the seventh pipeline 15 for temporary storage. When the cooling tower needs to use water, the staff controls the fourth reversing valve 11 to switch the passage, closes the passage between the sixth pipeline 13 and the fifth pipeline 10, opens the passage between the sixth pipeline 13 and the eighth pipeline 12, and then controls the pump body 14 to run in reverse after opening. In this way, the pump body 14 will pump the water in the clean water tank 16 into it, and then transmit it into the interior of the eighth pipeline 12 through the sixth pipeline 13 and the fourth reversing valve 11, and finally transmit it into the cooling tower through the eighth pipeline 12 for use. When the first filter cartridge 7 is filled with dirt or the internal filter screen is damaged, the staff controls the fourth reversing valve 11 to close the passage between the sixth pipeline 13 and the eighth pipeline 12 and open the passage between the sixth pipeline 13 and the fifth pipeline 10. After the switching is completed, the staff controls the second reversing valve 5 and the third reversing valve 9 to switch the passage. The second reversing valve 5 closes the passage between the second pipeline 4 and the third pipeline 6 and opens the passage between the second pipeline 4 and the ninth pipeline 19. The third reversing valve 9 closes the passage between the fifth pipeline 10 and the fourth pipeline 8 and opens the passage between the fifth pipeline 10 and the tenth pipeline 17. In this way, the water transmitted by the first pipeline 2 will directly be transmitted into the interior of the ninth pipeline 19 through the second pipeline 4, transmitted into the second filter cartridge 18 through the ninth pipeline 19 for filtration treatment, and the filtered water is transmitted into the interior of the fifth pipeline 10 through the tenth pipeline 17, and finally transmitted into the interior of the clean water tank 16 through the sixth pipeline 13, the pump body 14 and the seventh pipeline 15. When the staff needs to backwash the first filter cartridge 7 and the second filter cartridge 18, the staff controls the first reversing valve 3 to close the passage between the second pipeline 4 and the first pipeline 2 and open the passage between the second pipeline 4 and the eleventh pipeline 20. In this way, the water in the clean water tank 16 is pumped to backwash the first filter cartridge 7 and the second filter cartridge 18, and the sewage in the first filter cartridge 7 and the second filter cartridge 18 will be transmitted into the interior of the sewage tank 22 through the second pipeline 4 and the eleventh pipeline 20 for temporary storage. When there is too much sewage, the staff can open the solenoid valve 23 to drain it through the twelfth pipeline 21.
