Description

Technical Field

[0001] This utility model relates to the field of water filtration equipment, and in particular to a high-efficiency filtration device for water treatment. Background Technology

[0002] With population growth and accelerated industrialization, water resources are becoming increasingly polluted. Industrial wastewater contains large amounts of heavy metals, organic matter, and chemicals, while domestic sewage contains various pathogens, organic matter, and suspended solids. If these pollutants are discharged or used directly without treatment, they will cause serious harm to human health, the ecological environment, and industrial production. Heavy metals in water, such as mercury and cadmium, can accumulate in organisms and cause various diseases.

[0003] Early water treatment filtration primarily employed natural sedimentation and simple sand filtration. Natural sedimentation utilizes gravity to allow suspended particles in the water to gradually settle. Sand filtration, on the other hand, forces water through one or more layers of sand, the pores between which trap larger suspended particles. For instance, in ancient times, people used sand and gravel to filter drinking water. This method could remove some silt and impurities, but it was ineffective at filtering tiny pathogens and dissolved harmful substances.

[0004] Existing filtration equipment, such as the wastewater filtration equipment described in application number CN202322734180.3, suffers from the gradual clogging of the filter screen by impurities and particles in the wastewater over a long period of use, which slows down the filtration speed. When cleaning the filter screen, the impurities attached to the screen are often broken down into particles due to friction, and these particles become stuck in the gaps of the filter screen. During filtration, the particles in the gaps are forced through the filter screen by the impact of the water flow and mix with the filtered water. Utility Model Content

[0005] In view of the aforementioned application CN202322734180.3, which describes a wastewater filtration device, the present invention addresses the problem that, after prolonged use, impurities and particles in the wastewater gradually clog the filter screen, thus slowing down the filtration speed. Furthermore, during filter screen cleaning, impurities attached to the screen are often pulverized due to friction, and these pulverized particles clog the gaps in the filter screen. During filtration, these particles in the gaps are impacted by the water flow, causing them to pass through the filter screen and mix with the filtered water.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a high-efficiency filtration device for water treatment, comprising: a cylindrical shell and a Y-shaped water collection frame, wherein the Y-shaped water collection frame is provided at the lower end of the cylindrical shell, and an L-shaped connecting pipe is provided at the lower end of the Y-shaped water collection frame; a circular protective cover is installed at the upper end of the cylindrical shell; a cylindrical connecting rod is also provided inside the cylindrical shell; a cylindrical loading plate is also installed on the bottom surface inside the cylindrical shell; a circular connecting sleeve is installed on the upper surface of the cylindrical loading plate; an arc-shaped filter screen is also provided on the upper surface of the circular connecting sleeve; an arc-shaped connecting plate is provided above the arc-shaped filter screen; and a cleaning structure is also provided inside the arc-shaped filter screen, the cleaning structure comprising: a trapezoidal mounting rod and a water supply pipe.

An L-shaped water pipe is rotatably connected to the upper surface of the cylindrical connecting rod.

[0011] In a preferred embodiment of the high-efficiency filtration device for water treatment described in this utility model, the lower surface of the arc-shaped connecting plate is provided with several L-shaped connecting plates, and a circular ring plate is fixedly connected to the lower surface of the L-shaped connecting plate. The circular ring plate and the circular ring connecting sleeve are rotatably connected.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-2 Figures 5-6, representing the first embodiment of this utility model, provide a high-efficiency filtration device for water treatment, comprising: a cylindrical shell 1 and a Y-shaped water collection frame 2. The Y-shaped water collection frame 2 is provided at the lower end of the cross-section of the cylindrical shell 1, and an L-shaped connecting pipe is provided at the lower end of the cross-section of the Y-shaped water collection frame 2. The device is characterized in that: a circular protective cover is installed at the upper end of the cross-section of the cylindrical shell 1; a cylindrical connecting rod 3 is also provided inside the cylindrical shell 1; a cylindrical loading plate 4 is also installed on the bottom surface inside the cylindrical shell 1; a circular connecting sleeve 5 is installed on the upper surface of the cylindrical loading plate 4; an arc-shaped filter screen 6 is also provided on the upper surface of the circular connecting sleeve 5; an arc-shaped connecting plate 7 is provided above the arc-shaped filter screen 6; and a cleaning structure 8 is also provided inside the arc-shaped filter screen 6. The cleaning structure 8 includes: a trapezoidal mounting rod 9 and a water supply pipe 10.

[0026] A water supply pipe 10 is installed through the upper surface of the trapezoidal mounting rod 9. A rectangular fixing rod 11 is installed on the vertical surface of the trapezoidal mounting rod 9. The inner ring of each pair of rectangular fixing rods 11 is connected to the same rectangular outer shell 12. Several arc-shaped connecting pipes 13 are connected through the vertical surface of the rectangular outer shell 12 near the trapezoidal mounting rod 9. Several high-pressure nozzles 14 are installed on the vertical surface of the rectangular outer shell 12 away from the arc-shaped connecting pipes 13.

[0027] A rectangular mounting plate is provided on the vertical surface of the rectangular outer shell 12, and a rectangular outer frame 15 is provided on the vertical surface of the rectangular mounting plate away from the rectangular outer shell 12. A hard brush 16 is provided on the vertical surface of the rectangular outer frame 15 away from the trapezoidal mounting rod 9. A drive motor 17 is provided on the top of the cylindrical outer shell 1, and a pair of meshing bevel gears 18 are provided on the output end of the drive motor 17 and the rod body of the cylindrical connecting rod 3. An L-shaped water pipe 19 is rotatably connected to the upper surface of the cylindrical connecting rod 3.

[0028] After the arc-shaped filter screen 6 has been used for a long time, the drive motor 17 can be started directly. This is because the output end of the drive motor 17 and the cylindrical connecting rod 3 are equipped with a pair of meshing bevel gears 18. The upper surface of the cylindrical connecting rod 3 is rotatably connected to the L-shaped water pipe 19. Therefore, as the drive motor 17 rotates, the cylindrical connecting rod 3 will also rotate. Since the trapezoidal mounting rod 9 is fixedly connected to the cylindrical connecting rod 3, the trapezoidal mounting rod 9 will also rotate when the cylindrical connecting rod rotates. Before starting the drive motor 17, the water pump installed on the L-shaped water pipe 19, which is rotatably connected to the cylindrical connecting rod 3, should be started first.

[0029] This allows the mixed cleaning water to be input from the L-shaped water pipe 19 into the water supply pipe 10. Since the water supply pipe 10 is connected to several arc-shaped connecting pipes 13, and several arc-shaped connecting pipes 13 are connected through the vertical surface of the rectangular shell 12 near the trapezoidal mounting rod 9, and several high-pressure nozzles 14 are provided on the vertical surface of the rectangular shell 12 away from the arc-shaped connecting pipes 13, after the water pump is started, the mixed cleaning water will be sprayed out from the high-pressure nozzles, thereby spraying the gaps on the arc-shaped filter screen 6. As the trapezoidal mounting rod 9 rotates, the hard brush 16 rotates, thereby cleaning the residue in the gaps of the arc-shaped filter screen 6.

[0030] Example 2

[0031] Reference Figure 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: several L-shaped connecting plates 20 are provided on the lower surface of the arc-shaped connecting plate 7, and a circular ring plate 21 is fixedly connected to the lower surface of the L-shaped connecting plate 20. The circular ring plate 21 and the circular ring connecting sleeve 5 are rotatably connected. A rectangular scraper 22 is also provided on the lower surface of the circular ring plate 21. An arc-shaped scraper strip 23 is provided on the arc surface of a pair of L-shaped connecting plates 20 near the cylindrical connecting rod 3.

[0032] After the drive motor 17 starts, the cylindrical connecting rod 3 will rotate. Because the cylindrical connecting rod 3 has an arc-shaped connecting plate 7 that is penetrated through it, and the arc-shaped connecting plate 7 is fixedly connected to the cylindrical connecting rod 3, as the cylindrical connecting rod 3 rotates, the arc-shaped connecting plate 7 will also rotate, so that the arc-shaped scraper 23 set on the L-shaped connecting plate 20 will clean the impurities on the arc-shaped filter screen 6. The impurities that are scraped off will fall onto the upper surface of the cylindrical loading plate 4 due to their weight. Because the lower surface of the ring plate 21 is also provided with a rectangular scraper 22, and the ring plate 21 is rotatably connected to the ring connecting sleeve 5, when the arc-shaped connecting plate 7 rotates, the ring connecting sleeve 5 will also rotate, so that the rectangular scraper 22 will collect the scattered impurities and finally discharge them from the L-shaped drain pipe.

[0033] The remaining structure is the same as that in Example 1.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
