Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump filtering device. Background Art

[0002] A water pump is a device used to transport liquids and increase the pressure on liquids. Its main function is to transport liquid media such as water, oil, and suspensions. Water pumps are often used to transport water, but there are impurities in the water. Impurities enter the pump body with the water flow, which will cause the water pump to be damaged and reduce its life.

[0003] However, existing water pump filters usually filter water through a filter plate to prevent impurities from entering the pump body and damaging the water pump. The filter plate seems to be cleaned, but the cleaned impurities cannot be discharged. Over time, impurities are likely to accumulate on one side of the filter plate, causing blockage at the water inlet of the water pump, which is not conducive to the circulation of water. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

[0005] A water pump filter device comprises a pump body, both sides of which are connected to a water inlet pipe and a drain pipe, a sewage valve for discharging impurities is installed at the lower end of the water inlet pipe, a filter plate is fixedly connected to the inner cavity of the water inlet pipe, and an impurity cleaning mechanism for cleaning impurities is fixedly connected to the inner cavity of the water inlet pipe:

[0006] The impurity cleaning mechanism includes a fixed plate, a first rotating shaft, a groove and a cleaning plate. The fixed plate is fixedly connected to the inner cavity of the water inlet pipe, the first rotating shaft is rotatably connected to the fixed plate, the groove is opened on one side of the first rotating shaft, the cleaning plate is slidably connected to the inner cavity of the groove, and one side of the cleaning plate overlaps with one side of the filter plate.

[0007] As an improvement of the above technical solution, the impurity cleaning mechanism includes a second rotating shaft and a power plate, the second rotating shaft is rotatably connected to the filter plate, and one side of the second rotating shaft is clamped with one side of the first rotating shaft, and the power plate is fixedly connected to one side of the second rotating shaft.

[0008] As an improvement of the above technical solution, the impurity cleaning mechanism includes a spring, and both ends of the spring are fixedly connected to the inner cavity of the groove and one side of the cleaning plate.

[0009] As an improvement of the above technical solution, the inner cavity of the groove is rectangular and is slidably connected to one end of the cleaning plate.

[0010] As an improvement of the above technical solution, the end of the water inlet pipe close to the pump body is conical and matched with the power plate.

[0011] Beneficial effects of the utility model:

[0012] 1. Start the water pump to let water enter the water inlet pipe, and then filter through the filter plate inside the water inlet pipe. The water flows to the pump body and drives the impurity cleaning mechanism to rotate and clean the filter plate to prevent impurities from clogging the filter plate. Then the staff opens the drain valve to discharge the cleaned impurities through the drain valve to prevent impurities from accumulating on one side of the filter plate, thus preventing the water pump from being blocked and facilitating the circulation of water.

[0013] 2. The water flow drives the power plate to rotate, which in turn drives the second rotating shaft and the first rotating shaft to rotate. The rotation of the first rotating shaft drives the cleaning plate to rotate. The cleaning plate rotates to clean the filter plate to prevent impurities from clogging the filter plate. The elastic force of the spring is then used to overlap the cleaning plate with one side of the filter plate, so that the cleaning plate has a better cleaning effect on the filter plate, thereby ensuring the cleaning effect of the cleaning plate.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a water pump filter device, including a pump body 1, both sides of the pump body 1 are connected with a water inlet pipe 2 and a drain pipe 6, a sewage valve 3 for discharging impurities is installed at the lower end of the water inlet pipe 2, a filter plate 4 is fixedly connected to the inner cavity of the water inlet pipe 2, and an impurity cleaning mechanism 5 for cleaning impurities is fixedly connected to the inner cavity of the water inlet pipe 2:

[0021] The impurity cleaning mechanism 5 includes a fixed plate 501, a first rotating shaft 502, a groove 505 and a cleaning plate 507. The fixed plate 501 is fixedly connected to the inner cavity of the water inlet pipe 2, the first rotating shaft 502 is rotatably connected to the fixed plate 501, the groove 505 is opened on one side of the first rotating shaft 502, the cleaning plate 507 is slidably connected to the inner cavity of the groove 505, and one side of the cleaning plate 507 overlaps with one side of the filter plate 4.

[0022] By starting the pump body 1, water enters the water inlet pipe 2, and is filtered through the filter plate 4 inside the water inlet pipe 2. The filtered water then flows through the pump body 1 to the drain pipe 6, and is finally discharged from the drain pipe 6. The water flows to the pump body 1 and drives the impurity cleaning mechanism 5 to rotate to clean the filter plate 4 to prevent impurities from clogging the filter plate 4. Then, the personnel opens the drain valve 3, and the impurities and water are discharged through the drain valve 3 under the action of the water flow, so that the cleaned impurities are discharged through the drain valve 3, preventing impurities from accumulating on one side of the filter plate 4 for a long time, thereby preventing impurities from clogging the water pump, which is beneficial to the circulation of water.

[0023] Specifically, the impurity cleaning mechanism 5 includes a second rotating shaft 503 and a power plate 504. The second rotating shaft 503 is rotatably connected to the filter plate 4, and one side of the second rotating shaft 503 is clamped with one side of the first rotating shaft 502. The power plate 504 is fixedly connected to one side of the second rotating shaft 503.

[0024] The water flow drives the power plate 504 to rotate, thereby driving the second rotating shaft 503 and the first rotating shaft 502 to rotate. The rotation of the first rotating shaft 502 drives the cleaning plate 507 to rotate, and the cleaning plate 507 cleans the filter plate 4.

[0025] Specifically, the impurity cleaning mechanism 5 includes a spring 506 , and both ends of the spring 506 are fixedly connected to the inner cavity of the groove 505 and one side of the cleaning plate 507 .

[0026] The elastic force of the spring 506 is utilized to keep one side of the cleaning and filter plates 4 in an overlapping state, thereby ensuring the cleaning effect of the cleaning plate 507 on the filter plate 4 and making the cleaning effect of the cleaning plate 507 on the filter plate 4 better.

[0027] Specifically, the inner cavity of the groove 505 is rectangular and is slidably connected to one end of the cleaning plate 507 .

[0028] The rectangular groove 505 can limit the cleaning plate 507, so that the first rotating shaft 502 rotates through the groove 505 to drive the cleaning plate 507 to rotate, and then the cleaning plate 507 cleans the filter plate 4, thereby ensuring that the cleaning plate 507 cleans the filter plate 4.

[0029] Specifically, the end of the water inlet pipe 2 close to the pump body 1 is conical and matches with the power plate 504 .

[0030] One side of the inner cavity of the water inlet pipe 2 is tapered, so that water can be concentrated into the interior of the pump body 1, so that the water can more advantageously drive the power plate 504 to rotate, ensuring that the water flow has the power to rotate the power plate 504, thereby facilitating the rotation of the power plate 504 and increasing the stability of the cleaning plate 507 in cleaning the filter plate 4.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
