Description

Technical Field

[0001] This application relates to the field of water supply and drainage pre-filtration technology, and more specifically, to a drainage extraction pre-filtration structure for water supply and drainage engineering. Background Technology

[0002] Water supply and drainage engineering generally refers to the extraction, purification, and transportation of source water, as well as the collection, treatment, reuse, or discharge of wastewater. Before drainage and pumping, preliminary filtration is carried out to remove larger impurities and avoid clogging of subsequent pipes and pumps.

[0003] The prior art publication CN216571974U provides a drainage extraction pre-filtration device for water supply and drainage engineering, including a top cover and a filter box. A metal liquid pipe is connected to one side of the top cover, and a filter screen is installed inside the metal liquid pipe. A collection box is connected to the side of the metal liquid pipe near the filter screen. The top cover and the filter box are adapted to each other, and a connecting member for fixing is provided between the two sides of the top cover and the filter box. A filter plate is provided on the inner circumference of the filter box, and a reciprocating member for controlling the lifting and lowering of the filter plate is provided below the filter plate. A bottom plate is provided below the filter box, and lifting members for easy disassembly and assembly are provided on both sides of the bottom plate and the filter box.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] When water is filtered through a screen or plate, impurities cannot be removed in time. These impurities gradually clog the mesh of the screen and plate, making it difficult for water to flow and affecting pumping.

[0006] Regarding the aforementioned related technologies, the inventor believes that when filtering through a filter screen and filter plate, the filtered impurities cannot be removed in time, and the impurities will gradually clog the mesh of the filter screen and filter plate, resulting in difficulty in water flow and affecting water pumping.

[0007] In view of this, we propose a pre-filtration structure for drainage extraction in water supply and drainage engineering. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this application is to provide a pre-filtration structure for water extraction in water supply and drainage engineering, which solves the technical problem in the above-mentioned background technology that when filtering through filter screens and filter plates, the impurities filtered out cannot be removed in time, and the impurities will gradually clog the mesh of the filter screens and filter plates, resulting in difficulty in water flow and affecting water pumping, thus achieving the technical effect.

[0010] 2. Technical Solution

[0011] This application provides a pre-filtration structure for drainage extraction in water supply and drainage engineering, comprising:

[0012] Filter box;

[0013] A filter plate is fixedly installed in the inner cavity of the filter box;

[0014] Water inlet pipe: The top of the filter box is fixedly fitted with a water inlet pipe;

[0015] A water pumping pipe is fixedly sleeved on the bottom side wall of the filter box;

[0016] A cleaning mechanism is installed between the top of the filter plate and the filter box;

[0017] A collection frame is slidably attached to one side of the filter box.

[0018] With the above scheme, the water inlet pipe is connected to the external water channel, and the water pump is connected to the water pump. After the water flows into the filter box, it is filtered by the filter plate. Then, it gathers at the bottom of the filter box and is pumped away by the water pump. Impurities are intercepted by the filter plate. The cleaning mechanism gradually pushes the impurities to the collection frame for collection, keeping the filter plate unobstructed and facilitating rapid filtration.

[0019] Optionally, the filter plate has an inclined structure, and the lower end of the filter plate is fixedly connected to the inner wall of the filter box. There is a gap between the upper end of the filter plate and the inner wall of the filter box, and the collection frame is located at the bottom of the gap. The collection frame includes a sealing door plate, which is movably snapped onto the bottom of the side wall of the filter box. A mesh frame is fixedly installed on the inner wall of the sealing door plate, and the mesh frame is located at the bottom of the gap between the upper end of the filter plate and the inner wall of the filter box.

[0020] The above scheme allows the inclined filter plate to flow water towards the lower end during filtration, which facilitates increasing the filtration area and improving water flow efficiency. The cleaning mechanism gradually pushes impurities towards the upper end of the filter plate, and they eventually fall into the mesh frame through the gaps for collection. When not in use, the sealed door panel makes it easy to pull out the mesh frame and clean up the large amount of accumulated impurities.

[0021] Optionally, the cleaning mechanism includes a rotating shaft. Two rotating shafts are rotatably sleeved on the filter boxes on both sides of the filter plate. One end of each rotating shaft is fixedly connected to one end of a crank. The other end of the crank is rotatably connected to the side wall of the moving frame via a pin. The bottom of the moving frame is provided with multiple brush plates. A motor is fixedly installed on the outer wall of the filter box. The output shaft of the motor is fixedly connected to a rotating shaft. The distance between the axes of the two rotating shafts on the same side of the filter box is the same as the distance between the axes of the pin connecting the crank and the moving frame. The cranks are of the same length and parallel to each other. Multiple crossbars are fixedly installed between the inner walls of the moving frame. Sliding rods are slidably provided at both ends of each crossbar. A brush plate is fixedly connected to the bottom of each sliding rod. A retaining ring is fixedly installed at the top of each sliding rod. One end of a tension spring is fixedly connected to the bottom of the retaining ring. The other end of the tension spring is fixedly connected to the top of the crossbar.

[0022] With the above scheme, the motor drives one rotating shaft to rotate, and multiple rotating shafts rotate synchronously due to the transmission of the moving frame and crank. The crank, the shaft connection line, and the pin connection line on both sides of the filter box all form a rectangular structure. During the rotation of the rotating shaft, the moving frame remains horizontal and rotates clockwise as a whole. When the moving frame rotates clockwise to the downward section, the brush plate contacts the filter plate. At this time, the brush plate pushes the impurities to the upper end of the filter plate. As the moving frame moves to the lowest end of the downward section, the brush plate moves against the filter plate, causing the slide bar to move upward and the tension spring to stretch. When the moving frame moves from the lowest end of the downward section to the upward section, the tension spring force makes the brush plate continue to be in contact with the filter plate, thereby pushing the impurities to move. When the crank moves upward past the horizontal state, the brush plate disengages from the filter plate. This cycle is repeated to achieve unidirectional brushing of the filter plate by the brush plate, thereby gradually pushing the impurities into the collection frame.

[0023] 3. Beneficial effects

[0025] 1. In this application, water flows into the filter box and is filtered by the filter plate. The water then accumulates at the bottom of the filter box and is drawn away by the water pipe.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 This application provides a pre-filtration structure for drainage extraction in water supply and drainage engineering, comprising: a filter box 1; a filter plate 2, the filter plate 2 being fixedly installed in the inner cavity of the filter box 1; an inlet pipe 3, the inlet pipe 3 being fixedly sleeved on the top of the filter box 1; a pumping pipe 4, the pumping pipe 4 being fixedly sleeved on the bottom of the side wall of the filter box 1; a cleaning mechanism 5, the cleaning mechanism 5 being installed between the top of the filter plate 2 and the filter box 1; and a collection frame 6, the collection frame 6 being slidably snapped onto one side of the filter box 1. The inlet pipe 3 is connected to an external waterway, and the pumping pipe 4 is connected to a water pump. After the water flows into the filter box 1, it is filtered by the filter plate 2, and then accumulates at the bottom of the filter box 1 and is pumped away by the pumping pipe 4. Impurities are intercepted by the filter plate 2, and the cleaning mechanism 5 gradually pushes the impurities to the collection frame 6 for collection, keeping the filter plate 2 unobstructed and facilitating rapid filtration.

[0033] Reference Figure 1 and Figure 2 The filter plate 2 has an inclined structure, and the lower end of the filter plate 2 is fixedly connected to the inner wall of the filter box 1. There is a gap between the upper end of the filter plate 2 and the inner wall of the filter box 1, and the collection frame 6 is located at the bottom of the gap. The collection frame 6 includes a sealing door plate 61, which is movably snapped onto the bottom of the side wall of the filter box 1. A mesh frame 62 is fixedly installed on the inner wall of the sealing door plate 61. The mesh frame 62 is located at the bottom of the gap between the upper end of the filter plate 2 and the inner wall of the filter box 1. The inclined filter plate 2 causes the water to flow towards the lower end during filtration, which facilitates increasing the filtration area and improving the water flow efficiency. The cleaning mechanism 5 gradually pushes the impurities towards the upper end of the filter plate 2, and finally they fall into the mesh frame 62 from the gap for collection. When not in use, the sealing door plate 61 can easily pull out the mesh frame 62 to facilitate the cleaning of the large amount of accumulated impurities.

[0034] Reference Figures 2 to 4The cleaning mechanism 5 includes a rotating shaft 51. Two rotating shafts 51 are rotatably sleeved on the top of the filter box 1 on both sides of the filter plate 2. One end of the rotating shaft 51 is fixedly connected to one end of the crank 52, and the other end of the crank 52 is rotatably connected to the side wall of the moving frame 53 through a pin. Multiple brush plates 54 are provided at the bottom of the moving frame 53. A motor 55 is fixedly installed on the outer wall of the filter box 1. The output shaft of the motor 55 is fixedly connected to one rotating shaft 51. The distance between the axes of the two rotating shafts 51 on the same side of the filter box 1 is the same as the distance between the axes of the pin connecting the crank 52 and the moving frame 53. The cranks 52 are of the same length and parallel to each other. Multiple crossbars 7 are fixedly installed on the inner wall of the moving frame 53. Slide rods 8 are slidably passed through both ends of the crossbars 7. The bottom of the slide rods 8 is fixedly connected to the brush plate 54, and the top of the slide rods 8 is fixedly installed with a retaining ring 9. The bottom of the retaining ring 9 is fixedly connected to one end of a tension spring 10, and the other end of the tension spring 10 is fixedly connected to the top of the crossbar 7. The motor 55 drives one As the rotating shaft 51 rotates, multiple rotating shafts 51 rotate synchronously due to the transmission of the moving frame 53 and the crank 52. The connecting lines of the crank 52, rotating shaft 51, and pin on both sides of the filter box 1 form a rectangular structure. During the rotation of the rotating shaft 51, the moving frame 53 remains horizontal and rotates clockwise as a whole. When the moving frame 53 rotates clockwise to the downward section, the brush plate 54 contacts the filter plate 2. At this time, the brush plate 54 pushes the impurities to the upper end of the filter plate 2. As the moving frame 53 moves to the lowest end of the downward section, the brush plate 54 moves against the filter plate 2, causing the slide bar 8 to move upward and the tension spring 10 to stretch. When the moving frame 53 moves from the lowest end of the downward section to the upward section, the elasticity of the tension spring 10 causes the brush plate 54 to continue to be in contact with the filter plate 2, thereby pushing the impurities to move. When the crank 52 moves upward beyond the horizontal state, the brush plate 54 disengages from the filter plate 2. This cycle is repeated to achieve unidirectional brushing of the filter plate 2 by the brush plate 54, thereby gradually pushing the impurities into the collection frame 6.

[0035] Working principle: The inlet pipe 3 is connected to the external water channel, and the pumping pipe 4 is connected to the pump. After the water flows into the filter box 1, it is filtered by the filter plate 2. Then, it gathers at the bottom of the filter box 1 and is pumped away by the pumping pipe 4. Impurities are trapped by the filter plate 2. The inclined filter plate 2 causes the water to flow towards the lower end during filtration, which facilitates the increase of the filtration area and improves the water flow efficiency. The motor 55 drives a rotating shaft 51 to rotate. Multiple rotating shafts 51 rotate synchronously due to the transmission of the moving frame 53 and the crank 52. The connecting lines of the crank 52, the rotating shafts 51 and the pins on both sides of the filter box 1 form a rectangular structure. Therefore, while the rotating shafts 51 are rotating, the moving frame 53 remains horizontal and rotates clockwise as a whole. As the moving frame 53 rotates clockwise to the lower section, the brush plate 54 contacts the filter plate 2. At this time, the brush plate 54 pushes the impurities towards the upper end of the filter plate 2. As the moving frame 53 moves to the lowest end of the lower section, the brush plate 54 moves against the filter plate 2, causing the slide bar 8 to move upward and the tension spring 10 to stretch. When the lower end of the lower section moves to the upper section, the elastic force of the tension spring 10 makes the brush plate 54 continue to be in contact with the filter plate 2, thereby pushing the impurities to move. When the crank 52 moves upward past the horizontal state, the brush plate 54 disengages from the filter plate 2. This cycle is repeated to achieve unidirectional brushing of the filter plate 2 by the brush plate 54, thereby gradually pushing the impurities into the collection frame 6.
