Description

Technical Field

[0001] This utility model relates to the field of water pump installation technology, and in particular to a complete set of water pump inlet and outlet equipment with filtration function. Background Technology

[0002] When a water pump is operating, dirt and impurities in the water often enter the pump along with the water, directly affecting its normal operation. Larger particles of dirt and impurities can damage the pump. The current solution is to use a filter screen over the pipe at the pump inlet to remove impurities. However, because the filter screen has a small flow area, it is easily clogged by dirt and impurities, affecting the pump's flow rate and directly impacting its efficiency, increasing the risk of damage, and reducing its lifespan. Increasing the flow area of ​​the filter screen, on the other hand, would result in more impurities in the water pumped out, potentially damaging the pump's impeller and other components. Utility Model Content

[0003] The purpose of this utility model is to provide a complete set of inlet and outlet equipment for a water pump with filtration function to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A complete set of inlet and outlet equipment for a water pump with filtration function includes a water pump. The inlet of the water pump is equipped with a filter box, and the outlet of the water pump is connected to a water tank through a pipe. The filter box includes a first frame, a second frame, a first wire mesh, and a second wire mesh. The first frame is fixedly installed inside the second frame. The first wire mesh is fixedly connected to the first frame and completely covers the first frame. The second wire mesh is fixedly connected to the second frame and completely covers the second frame. The aperture of the first wire mesh is smaller than the aperture of the second wire mesh. A partition is fixedly installed at the bottom of the second frame, and a barrier is fitted at the bottom end of the second frame to close the bottom end of the second frame.

[0006] By adopting the above technical solution, after the water pump is placed in the area where water needs to be drawn, the impurities in the water are filtered by the second wire mesh on the second frame and then by the first wire mesh on the first frame, thus filtering out large solid particles in the water and preventing large particles from entering the water pump inlet and causing damage to the internal structure of the water pump.

[0007] In a further embodiment, the water tank is provided with multiple layers of filter cotton inside, the top of the water tank is provided with an interface communicating with the water pump outlet pipe, the bottom of the water tank is provided with a drain outlet, and a pressure ring is installed inside the water tank in a sliding manner.

[0008] By adopting the above technical solution, the multi-layer filter cotton inside the water pump's water cup and water tank achieves a higher water quality, making it easier to use.

[0009] In a further embodiment, a clamp is fixedly installed at the bottom end of the water pump, the clamp being used to hold the second frame securely to the bottom end of the water pump.

[0010] In a further embodiment, the outlet of the water pump is equipped with a flow detection valve.

[0011] In a further embodiment, a level gauge is fixedly installed inside the water tank.

[0012] By adopting the above technical solution, the liquid level inside the water tank is measured, and water is added to the water tank by a water pump when the liquid level is insufficient.

[0013] In a further embodiment, the water tank consists of a tank body and an end cap, which are detachably connected.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. After the water pump is placed in the area where water needs to be drawn, the impurities in the water are filtered by the second wire mesh on the second frame and then by the first wire mesh on the first frame. This filters out large solid particles in the water, preventing them from entering the water pump inlet and causing damage to the pump's internal structure. Attached Figure Description

[0022] Example 1:

[0023] like Figures 1-3 As shown, a complete set of inlet and outlet equipment for a water pump with filtration function includes a water pump 1. A filter box 2 is installed at the inlet of the water pump 1, and the outlet of the water pump 1 is connected to a water tank 3 via a pipe. The filter box 2 includes a first frame 21, a second frame 22, a first wire mesh 23, and a second wire mesh 24. The first frame 21 is fixedly installed inside the second frame 22. The first wire mesh 23 is fixedly connected to the first frame 21 and completely covers the first frame 21. The second wire mesh 24 is fixedly connected to the second frame 22 and completely covers the second frame 22. The aperture of the first wire mesh 23 is smaller than the aperture of the second wire mesh 24. A partition 4 is fixedly installed at the bottom of the second frame 22, and a retaining 5 is fitted at the bottom end of the second frame 22 to close the bottom end of the second frame 22. The water tank 3 is equipped with multiple layers of filter cotton 6. The top of the water tank 3 is equipped with an interface that connects to the outlet pipe of the water pump 1. The bottom of the water tank 3 is equipped with a drain outlet. A pressure ring 7 is installed inside the water tank 3 and slides up and down. A clamp is fixedly installed at the bottom end of the water pump 1 to hold the second frame 22 to the bottom end of the water pump 1. A flow detection valve is installed at the outlet of the water pump 1. A liquid level detector is fixedly installed inside the water tank 3. The water tank 3 consists of a tank body and an end cover, which are detachably connected.

[0024] Specific implementation process: When using a water pump, it is often placed directly at the bottom of the area where water needs to be drawn. Due to the complexity of the environment, the bottom of the water intake area contains mud, sand, and gravel. Therefore, in order to extend the service life of the water pump and avoid frequent failures during use, after the water pump is placed in the area where water needs to be drawn, the impurities in the water are filtered by the second wire mesh on the second frame and then by the first wire mesh on the first frame. This filters out large solid particles in the water, preventing them from entering the water pump inlet and causing damage to the internal structure of the water pump. Existing technology solves this problem by wrapping filter cloth around the water pump inlet, but the filter cloth is not strong and can easily affect the water pump's intake because the pore size of the filter plate is too small.

[0025] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
