Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a filtration device for a water pump. Background Technology

[0002] Water supply pumps are a widely used type of pump. They are characterized by good sealing, leak-free operation, and corrosion resistance, and are commonly used in environmental protection, water treatment, and fire protection departments to pump various liquids. The application scenarios for water supply pumps are diverse, and they are often used to extract liquids. Because of these varied applications, the liquids pumped by water supply pumps often contain a large amount of impurities, such as small particles, leaves, and pebbles. These impurities can damage the high-pressure water supply pump if they enter it, thus requiring the use of a filtration device.

[0003] The existing water pumps have relatively simple filtration devices, which usually rely on one or more layers of filter screens. However, using only filter screens can easily cause them to become clogged when there are impurities such as leaves in the water pumped by the pump. This requires frequent replacement of the filter screens and affects the efficiency of the water pump.

[0004] Therefore, it is necessary to design a filtration device for the water pump to improve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a filtration device for a water pump. This filtration device aims to solve the technical problem that impurities in the water easily clog the filter screen, affecting filtration efficiency and requiring frequent replacement and cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filtration device for a water pump includes a connector, with mounting rings fixedly connected to both sides of the connector. Three sets of filter screens are installed inside the connector. A collection trough is fixedly connected to the bottom of the connector below the filter screens. A collection tray is slidably connected to the bottom side of the collection trough. A cleaning component is installed on the top of the connector above the filter screens.

[0008] Preferably, mounting holes are provided on all four sides of the mounting ring, a mating ring is fixedly connected to the side of the mounting ring away from the connector, and a rubber layer is fixedly connected to the outer side of the mating ring.

[0009] Preferably, the sides of the collection drawer are fixedly connected with sealing strips, and a set of fixing buckles are hinged to both sides of the collection drawer, with anti-slip textures on the outer side of the fixing buckles.

[0010] Preferably, a pull rod is fixedly connected to the side of the collection drawer away from the material collection trough.

[0011] Preferably, the cleaning assembly consists of a limiting slide bar, a return spring, a connecting frame, a connecting rod, and an arc-shaped scraper.

[0012] Preferably, the top of the connector is fixedly connected to two sets of limiting slide rods above the filter screen, and a connecting frame is slidably connected between the two sets of limiting slide rods. A return spring is sleeved on the outer side of the limiting slide rod below the connecting frame.

[0013] Preferably, the connecting frame has a sliding hole at the position corresponding to the limiting slide rod, and the connecting frame is slidably connected to the limiting slide rod through the sliding hole. A second pull rod is fixedly connected to the top of the connecting frame, and a connecting rod is fixedly connected to the bottom of the connecting frame at the position corresponding to the filter screen. A movable hole is opened at the top of the connecting member at the position corresponding to the connecting rod. A sealing ring is provided on the inner wall of the movable hole. An arc-shaped scraper is fixedly connected to the bottom of the connecting rod, and a brush is fixedly connected to the side of the arc-shaped scraper corresponding to the filter screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

The docking ring 102 is embedded in the inlet pipe of the water supply pump, allowing the filter device to quickly dock with the water supply pump. A rubber layer 1021 is fixedly connected to the outer side of the docking ring 102, enhancing the sealing at the docking point between the filter device and the water supply pump.

[0026] In this embodiment, please refer to Figure 1 and Figure 2The connector 1 has three sets of filter screens 2 installed inside. The filter screens 2 intercept and filter impurities in the water. The bottom of the connector 1 is fixedly connected to the collection trough 201 below the filter screens 2. The bottom side of the collection trough 201 is slidably connected to the collection tray 202. The collection tray 202 collects the intercepted impurities and garbage. The sides of the collection tray 202 are fixedly connected to the sealing strips 2021. The sealing strips 2021 enhance the sealing performance of the collection tray 202 after it is closed. Both sides of the collection tray 202 are hinged with a set of fixing buckles 2022. The collection tray 202 is fixedly engaged with the side of the connector 1 by the fixing buckles 2022, which improves the installation stability of the collection tray 202. The outer side of the fixing buckles 2022 is provided with anti-slip texture. The side of the collection tray 202 away from the collection trough 201 is fixedly connected to the pull rod 2023. The pull rod 2023 facilitates the pulling of the collection tray 202 for loading, unloading and cleaning.

[0027] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the connector 1 is located above the filter screen 2 and a cleaning component 3 is installed. The cleaning component 3 consists of a limiting slide bar 301, a return spring 302, a connecting frame 303, a connecting rod 304 and an arc-shaped scraper 305.

[0028] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Two sets of limiting slide rods 301 are fixedly connected to the top of connector 1 above filter screen 2. A connecting frame 303 is slidably connected between the two sets of limiting slide rods 301. A return spring 302 is sleeved on the outer side of the limiting slide rods 301 below the connecting frame 303. The return spring 302 uses its own elasticity to push the connecting frame 303 to automatically return to its original position.

The filter device is installed and fixed by bolts to the water pump through the mounting hole 1011 on the mounting ring 101. When the water pump is working, the water passes through the filter screen 2, which intercepts and blocks solid impurities in the water. When solid impurities accumulate to a certain amount, the pull rod 3032 pushes the connecting frame 303 to slide through the sliding hole 3031 and connect with the limiting slide rod 301. The connecting rod 304 drives the arc-shaped scraper 305 to scrape the water. Impurities in the water on the surface of filter screen 2 are pushed into the collection trough 201 to scrape and clean the filter screen 2. Brush 3051 cleans the filter holes of filter screen 2 that are blocked. The fixing buckle 2022 is released from the side of the connector 1. Pull rod 1 2023 makes it easy to pull the collection tray 202 for disassembly. After cleaning solid impurities, it is reinstalled into the collection trough 201. The collection tray 202 is fixed to the side of the connector 1 by the fixing buckle 2022, which improves the installation stability of the collection tray 202. The reset spring 302 makes it easy to push the connecting frame 303 to automatically reset through its own elasticity.

[0030] The entire operation process is simple and convenient. Compared with existing filtration devices, this utility model is designed to facilitate the rapid cleaning of solid impurities intercepted on the filter screen, avoiding frequent disassembly and cleaning of the filter screen and improving overall practicality.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
