Description

Technical Field

[0001] The present application relates to the technical field of high-pressure pumps, and in particular to a water inlet filter device for a high-pressure pump. Background Art

[0002] The high-pressure pump inlet filtration device is a device used to ensure that the water quality of the high-pressure pump inlet is pure and free of impurities. Commonly used filtration devices include strainers, filters, etc., which can effectively remove suspended matter, particulate matter, sand and other impurities in the water and improve the purity of the inlet water quality.

[0003] After searching, the announcement number is CN214781076U, which discloses a water purification filtration system with an automatic filter element flushing device, including an early filtration system, a water inlet solenoid valve, a high-pressure pump, a control system, a membrane filtration system, an online water quality monitor, a high-pressure valve, a filter element flushing system, a clean water bucket, and a post-activated carbon filter. A flushing nozzle is arranged on the top of the inner part of the membrane shell cover of the membrane filtration system, and a flushing water pipe interface is arranged on the outer part of the membrane shell cover. The other end of the flushing water pipe interface is connected to the clean water bucket, and a flushing solenoid valve and a booster pump are arranged between the flushing water pipe interface and the clean water bucket. When the online water quality monitor detects that the value of the clean water filtered after the membrane filter is greater than the set value, the control system opens the flushing solenoid valve and the booster pump for flushing. The water after flushing the filter element will be recycled to the early filtration system for re-filtration to avoid waste of water resources. The flushing process is automatically controlled by the control system throughout, saving labor costs and extending the service life of the filter element.

[0004] However, although the existing water inlet filter device of the high-pressure pump can provide a filtering effect for the water source, when the filter is actually used, there is a problem that due to the long-term use of the filter, the filter element accumulates too many impurities and pollutants, which on the one hand affects the filtering effect, and on the other hand leads to a reduction in water output, causing blockage of the water channel, making it impossible for users to directly obtain information on replacing the filter element.

[0005] Therefore, it is necessary to provide a high-pressure pump water inlet filtering device to solve the above problems.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0039] See also Figure 1 , the utility model provides the embodiment:

[0040] A high-pressure pump water inlet filter device comprises a water storage tank 1 and a water pump 10, wherein the water storage tank 1 is docked and installed with the water inlet of the water pump 10 through a water guide pipe 14, the water outlet of the water pump 10 is docked and connected with one end of a water outlet connecting pipe 11, and the other end of the water outlet connecting pipe 11 is docked and installed with the water inlet end of the filter 6;

[0041] The filter 6 includes a first filter element 61, a first connecting water pipe 62, a second filter element 63, a second connecting water pipe 64 and a third filter element 65. The water inlet end of the first filter element 61 is docked and installed with the other end of the water outlet connecting pipe 11, the water outlet end of the first filter element 61 is docked and installed with one end of the first connecting water pipe 62, the other end of the first connecting water pipe 62 is docked and installed with the water inlet end of the second filter element 63, the water outlet end of the second filter element 63 is docked and installed with one end of the second connecting water pipe 64, the other end of the second connecting water pipe 64 is docked and installed with the water inlet end of the third filter element 65, the water outlet end of the third filter element 65 is docked and installed with the water outlet pipe 7, and the water outlet pipe 7 can also be connected to a faucet or other water-using equipment, so that the user can directly obtain the filtered clean water source;

[0042] The first filter element 61, the second filter element 63 and the third filter element 65 filter layer by layer to ensure that the water discharged from the water tank 1 is cleaner.

[0043] The outlet connecting pipe 11 is located at the outlet of the water pump 10 and is equipped with a pre-filter pressure sensor 9. The outlet of the outlet pipe 7 is equipped with a post-filter pressure sensor 8. Through the data of the pre-filter pressure sensor 9 and the post-filter pressure sensor 8, it is possible to detect and judge whether the filter element needs to be replaced. Under normal circumstances, when the use time is long or the water quality is dirty, the pressure detected by the pre-filter pressure sensor 9 will gradually increase, indicating that the water quality at the water inlet has deteriorated, and the filter element begins to accumulate impurities and pollutants, resulting in increased pressure; and the pressure detected by the post-filter pressure sensor 8 will increase accordingly, indicating that the filtering effect of the filter 6 has decreased and the filter element needs to be replaced. For example, assuming that in the initial state, the reading of the pre-filter pressure sensor 9 is 100, and the reading of the post-filter pressure sensor 8 is 50. This indicates that the water quality at the current water inlet is good and the filtering effect of the filter element is also good. With the passage of time and the change of water quality, the reading of the pre-filter pressure sensor 9 gradually increases to 150, and the reading of the post-filter pressure sensor 8 also increases to 80. In this case, it can be judged that the filter element needs to be replaced.

[0044] In order to further increase the water output of the water tank 1, the side wall of the water tank 1 and the bottom of the water tank 1 are respectively connected to one end of the water pipe 14, and the other ends of the two water pipes 14 are connected to the water inlet of the water pump 10. By increasing the number of water pipes 14, the resistance of the water flow can be reduced, the flow speed of the water can be increased, and the water intake can be increased. Water can be transported from the water tank 1 to the water pump 10 more quickly, thereby improving the operating efficiency of the system.

[0045] A water tank water inlet pipe 2 is installed at the bottom of the water tank 1 to be able to replenish water for the water tank 1.

[0046] A first branch pipe 12 is installed on the side wall of the water outlet connecting pipe 11, and a pre-filter pressure gauge 4 is installed at the end of the first branch pipe 12. A second branch pipe 13 is installed on the side wall of the water outlet end of the water outlet pipe 7 located at the third filter element 65, and a post-filter pressure gauge 5 is installed at the end of the second branch pipe 13. The main function of installing the pre-filter pressure gauge 4 before the water inlet of the three groups of filter elements is to monitor the pressure before the water inlet, so as to timely detect the deterioration of the filtering effect of the filter element or the increase of the resistance, and remind the user to replace the filter element in time to ensure the filtering effect. The main function of installing the post-filter pressure gauge 5 after the water outlet of the three groups of filter elements is to monitor the pressure after the water outlet, so as to detect whether the filter element is blocked or whether the replacement cycle has arrived, and ensure the quality and flow of the outlet water. In this way, the filter element can be monitored and maintained in time to ensure the normal operation of the entire filtration system.

[0047] In order to provide users with a variety of options, a drain pipe 3 is also installed on the side wall of the water outlet connecting pipe 11. Through the drain pipe 3, the user can choose whether to filter the water source of the water storage tank 1 according to the purpose of water use, thereby providing a variety of options.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
