As shown in Figures 1 to 5, the self-cleaning pump pre-filter device is provided in this embodiment, including a main body 1 suspended in the water body 2, the main body 1 has a water outlet 111, and can be connected to the water pump 3 to filter the water pump 3 role. The main body 1 includes a rotatable filter cartridge 11 and a raw water pipe 137 passing through the filter cartridge 11 , and a water outlet 111 is provided at one end of the raw water pipe 137 . A nozzle assembly 135 capable of outputting high-pressure water flow is erected on the raw water pipe 137 , and a plurality of nozzles 1351 facing the inner wall of the filter cartridge 11 are arranged on the nozzle assembly 135 .

When in use, the water pump 3 starts to absorb water, and the water in the water body 2 enters the raw water pipe 137 after being filtered by the filter screen 112 on the side wall of the filter cartridge 11, and is sucked away by the water pump 3 at last. At the same time, there is a high-pressure water flow inside the nozzle assembly 135, which is sprayed toward the inner wall of the filter cartridge 11 through a plurality of nozzles 1351. After the high-pressure water is sprayed on the inner wall, it passes through the filter screen 112 to wash away the external impurities, and keeps the sprayed part of the filter screen 112. cleanliness. Since the filter cartridge 11 can be rotated, it can ensure that the entire inner wall is completely sprayed after one rotation, which not only enables all parts of the entire filter screen 112 to be cleaned, but also does not affect the operation of other parts during the cleaning process. The cleaning of the filter cartridge 11 is continuously guaranteed during its work, so that it can be used for a long time without worrying about the problem that the filter screen 112 is blocked. The maintenance cost is low, the reliability is strong, and the service life is long.

When the nozzle 1351 sprays high-pressure water to rinse the filter cartridge 11, the water passes through the filter screen 112, carrying impurities into the dirt collection cover 123, and concentrates the impurities attached to the outside of the filter cartridge 11 in the dirt collection cover 123 to prevent the impurities from falling back. The water body 2 may fall on other parts of the main body 1, causing secondary pollution.

In order to collect the impurities in the dirt collection cover 123, the dirt collection cover 123 is arranged in an arc shape, and a dirt collection tank 1232 is provided at its lower end. . A sewage discharge port 1231 is also provided on the sewage collection cover 123, and the sewage discharge port 1231 is connected to the sewage collection tank 1232, and the impurities collected in the sewage collection tank 1232 can be discharged to complete the entire sewage collection process.

There are many ways to rotate the filter cartridge 11. For example, the driving wheel 1331 is directly connected to the motor output end, and the transmission structure adopts a gear set to pass through. Specifically, the main body 1 in this embodiment also includes a water turbine 131, and one end of the water turbine 131 is set There is a water wheel inlet 1311 for high-pressure water to flow in, the other end is provided with a water wheel outlet 1313, and an impeller 1312 is arranged inside. When the high-pressure water flows through the impeller 1312, the impeller 1312 is driven to rotate, and the impeller 1312 is connected to the driving wheel 1331 to provide The power finally drives the filter cartridge 11 to rotate. The water wheel outlet 1313 communicates with the nozzle assembly 135 through the cleaning water pipe 134 . Since the nozzle assembly 135 needs to input high-pressure water flow, the method adopted in this implementation is to connect the water turbine 131 in series on the waterway of the high-pressure water flow, push the impeller 1312 to rotate with the help of water pressure, and finally drive the filter cartridge 11 to rotate, without installing an additional power device , only with the help of high-pressure water flow, the structure is relatively simple, and the high-pressure water flow can be "one thing for two purposes".

The transmission structure in this embodiment is a belt 133, correspondingly, the driving pulley 1331 and the driven pulley 1332 are two pulley structures with a certain proportion. In practice, other structures such as connecting rods, chains, and gear sets can also be used for transmission.

The whole water pumping system applied by the self-cleaning pump pre-filter device in this embodiment is shown in Figure 4 or Figure 5. In Figure 4, the water pump 3 directly provides high-pressure water flow for cleaning and pushing the impeller 1312, which passes through the main water pipe 31 The output flows into the cleaning water source pipe 34 through the anti-clogging filter 32 and the manual ball valve 33, and finally connects to the cleaning water pipe 134 (connected to the water wheel inlet 1311), and the water pump 3 sucks in water from the main source water pipe 35 connected to the water outlet 111.

In the system shown in Fig. 5, its general process is the same as that shown in Fig. 4, and the water pump 3 provides water flow, which is output through the main water pipe 31, passes through the anti-clogging filter 32, the manual ball valve 33, and flows into the cleaning water source pipe 34, and finally Connect the cleaning water pipe 134 (connected to the water wheel inlet 1311), and the water pump 3 draws in water from the main source water pipe 35 connected to the water outlet 111. The difference is that the water pump 3 does not directly provide high-pressure water flow, and the output water flow is pressurized under the action of the high-pressure water pump 4 to form a high-pressure water flow for cleaning and driving the impeller 1312 .

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
