Description
Technical Field
[0001] This invention relates to the field of water treatment, and more specifically to a V-type filter. Background Technology
[0002] V-type filters are rapid filters named for the V-shaped shape of their inlet tanks. Their main features are uniform water distribution, good backwashing effect, and the combination of air and water backwashing with constant lateral surface cleaning, which greatly reduces the amount of backwash water.
[0003] In the prior art, utility model patent application number CN202021848574.1 discloses a V-shaped filter for sewage treatment. In this filter, two sets of cleaning scrapers are fixedly installed on two sets of driving devices. The driving devices drive the cleaning scrapers to scrape the inner wall of the V-shaped water inlet tank, thereby achieving the purpose of cleaning.
[0004] However, the aforementioned V-type filter can only clean the inner wall of the inlet tank, but does not have the function of cleaning the water inlet. After a long period of use, impurities and dirt contained in the unfiltered water are easily attached to the inner wall of the water inlet, which leads to a reduction in the water output or even blockage of the water inlet, affecting the normal operation of the V-type filter. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a V-shaped filter that allows for easy cleaning and unblocking of the water distribution holes.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a V-shaped filter tank, comprising a tank body, wherein a filter tank and a drain tank located on the side of the filter tank are provided in the tank body, and an elongated water inlet trough is fixedly installed on the inner wall of the tank body corresponding to the filter tank. The water inlet trough has a V-shaped cross-section, and a plurality of water distribution holes are provided on one side wall of the water inlet trough at uniform intervals along its length direction; a collection tank is fixedly installed in the tank body, one end of the water inlet trough is connected to the collection tank, and a movable frame driven by a driving mechanism and moving along a length direction parallel to the water inlet trough is provided in the tank body. A scraping component for scraping the dirt in the water inlet trough toward the collection tank is installed on the movable frame, and a cleaning component for cleaning the water distribution holes is also installed on the movable frame.
[0007] As a further improvement, the scraping assembly includes a horizontal arm fixedly mounted on the movable frame, and a scraper is installed below the horizontal arm. The scraper is triangular in shape and fits against the inner wall of the water inlet tank. The scraper is provided with water-permeable holes.
[0008] As a further improvement, a lifting cylinder with a piston rod extending downwards is installed on the cross arm, and the scraper is fixedly installed on the piston rod of the lifting cylinder.
[0009] As a further improvement, the cleaning assembly includes a cleaning motor, on which a cleaning rod matching the water distribution hole is coaxially fixedly mounted. The axis of the cleaning rod is parallel to the axis of the water distribution hole, and bristles are provided on the outer side of the cleaning rod. The cleaning motor is driven by a telescopic component and moves in a direction parallel to the axis of the water distribution hole.
[0010] As a further improvement, a guide rail is fixedly installed on the movable frame, the guide rail extends along an axis parallel to the water distribution hole, and a motor housing is slidably installed on the guide rail, with the cleaning motor installed inside the motor housing.
[0011] As a further improvement, the telescopic component includes a cleaning cylinder mounted on the movable frame, the piston rod of the cleaning cylinder extending along an axis parallel to the water distribution hole, and the motor housing being fixedly connected to the piston rod of the cleaning cylinder.
[0012] As a further improvement, the water inlet trough is provided with a vertical wall attached to one side wall of the pool body and an inclined wall away from the side wall of the pool body, and the inner side of the vertical wall is provided with an inclined surface that slopes inward from top to bottom.
[0013] As a further improvement, the collection tank is equipped with a collection tray, on which multiple filter holes are evenly distributed; a vertically extending support column is installed on one side of the top of the pool, and a cantilever is fixedly installed on one side of the upper end of the support column. A winch is installed on the top of the cantilever, and a steel wire rope is wound on the winch. The collection tray is fixedly connected to the free end of the steel wire rope.
[0014] As a further improvement, a guide wheel is rotatably mounted at the end of the cantilever away from the supported column, and the free end of the wire rope passes downward around the guide wheel and connects to the collection tray.
[0015] As a further improvement, the lower end of the support column is rotatably mounted on a drive box, which is also equipped with an adjustment motor for driving the support column to rotate around its own axis.
[0016] Compared with the prior art, the present invention has the following advantages: 1. This application uses a movable frame to drive a scraper to efficiently remove dirt from the inner wall of the water inlet tank. At the same time, a cleaning rod with bristles and driven by a cleaning motor rotates and brushes each water distribution hole separately, thereby avoiding blockage of the water distribution holes, ensuring smooth water flow from the water distribution holes, and improving the stability of the V-type filter operation. 2. This application provides a collection tray inside the collection tank to collect the waste scraped from the inlet tank. With the help of a winch, a rotatable support column and a cantilever, the collection tray can be easily lifted and transferred to the outside of the tank, making the collection and cleaning of waste more convenient.

Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0021] like Figures 1 to 6 As shown, a V-shaped filter includes a tank body 1, a filter tank 2 and a drain tank 3 located on the right side of the filter tank 2, as shown. Figure 3 As shown, the filter tank 2 and the sewage discharge tank 3 are separated by a front-to-back extending baffle plate 4. The filter tank 2 is equipped with filter media. A water inlet tank 5 is fixedly installed on the left side wall of the tank body 1 by bolts. The water inlet tank 5 is located above the filter tank 2 and the bottom of the water inlet tank 5 is higher than the top of the baffle plate 4. The water inlet tank 5 is a long strip extending front-to-back. The cross-section of the water inlet tank 5 is V-shaped. The water inlet tank 5 has a vertical wall on the left side and an inclined wall on the right side. The inclined wall of the water inlet tank 5 has a plurality of water distribution holes 6 evenly spaced along its length. The axis of the water distribution holes 6 extends horizontally or at a certain angle to the horizontal plane.
[0022] During the filtration stage, the water to be filtered is injected into the inlet tank 5 through a water pipe, and then overflows from the top of the inlet tank 5 and flows into the filter tank 2 through the water distribution hole 6. After being filtered by the filter media in the filter tank 2, the water is discharged from the pipe pre-installed at the bottom of the filter tank 2. During the backwashing stage, water and air are aerated into the filter tank 2 through the pipe pre-installed at the bottom of the filter tank 2. The backwash water in the filter tank 2 overflows from the top of the baffle plate 4 to the drain tank 3, and at the same time, water flows out through the water distribution hole 6 to flush the dirt on the surface of the filter tank 2 into the drain tank 3.
[0023] A collection trough 7 is fixedly installed inside the pool body 1 by bolts. One end of the inlet trough 5 is connected to the collection trough 7. Specifically, the front end of the inlet trough 5 is closed, and the rear end of the inlet trough 5 extends into the collection trough 7 in an open state. An opening is provided on the front side wall of the collection trough 7 for the rear end of the inlet trough 5 to enter, and the rear end of the inlet trough 5 is flush with the inner side of the front side wall of the collection trough 7.
[0024] like Figure 3 and Figure 4 As shown, the pool body 1 is equipped with a movable frame 8 that is driven by a drive mechanism and moves back and forth along the length direction parallel to the water inlet trough 5. Specifically, a support plate 9 is welded to the right side of the collection trough 7. A sliding rod 10 extending back and forth is fixed between the support plate 9 and the front side wall of the pool body 1 by bolts. The movable frame 8 is slidably mounted on the sliding rod 10. A drive motor 11 is also mounted on the support plate 9 by screws. The output end of the drive motor 11 is connected to a lead screw 12 that is parallel to the sliding rod 10. The end of the lead screw 12 away from the drive motor 11 is rotatably connected to the front side wall of the pool body 1 through a bearing. The drive motor 11 drives the lead screw 12 to rotate, and then the lead screw 12 drives the movable frame 8 to move back and forth along the sliding rod 10.
[0025] A scraping assembly is installed on the movable frame 8 to scrape the dirt in the water inlet tank 5 towards the collection tank 7. The scraping assembly includes a horizontal arm 13 fixed to the movable frame 8 by bolts. The horizontal arm 13 extends to the left above the water inlet tank 5, and a scraper 14 is installed below the horizontal arm 13. The scraper 14 is triangular in shape and fits against the inner wall of the water inlet tank 5. The center of the scraper 14 is hollowed out to form a water permeable hole 15. As the movable frame 8 moves back and forth, it drives the scraper 14 to move synchronously, thereby scraping away the dirt attached to the inner wall of the water inlet tank 5, achieving the cleaning effect of the water inlet tank 5.
[0026] Additionally, a lifting cylinder 16 with a downwardly extending piston rod is bolted to the cross arm 13, and a scraper 14 is bolted to the piston rod of the lifting cylinder 16. Specifically, when the movable frame 8 moves the scraper 14 backward toward the collection tank 7, the lifting cylinder 16 extends, causing the scraper 14 to descend and contact the inner wall of the water inlet tank 5, so that the scraper 14 can scrape the dirt adhering to the inner wall of the water inlet tank 5 toward the collection tank 7; when the movable frame 8 moves the scraper 14 forward away from the collection tank 7, the lifting cylinder 16 retracts, causing the scraper 14 to rise and disengage from the inner wall of the water inlet tank 5, thereby preventing dirt from accumulating in the end of the water inlet tank 5 away from the collection tank 7.
[0027] In this embodiment, the water inlet tank 5 is provided with a left vertical wall 17 and a right inclined wall 18. The outer side of the vertical wall 17 is attached to the inner side of the left side wall of the tank body 1. The vertical wall 17 and the inclined wall 18 are distributed in a V-shape, as shown below. Figure 4 As shown, the inner side of the vertical wall 17 is provided with an inclined surface that slopes inward from top to bottom, so that the scraper 14 can be completely separated from the vertical wall 17 and the inclined wall 18 when it rises.
[0028] To facilitate the cleaning of waste in the collection tank 7, a collection tray 19 is provided at the bottom of the collection tank 7, and multiple filter holes are evenly distributed on the bottom wall of the collection tray 19. The depth of the collection tank 7 is greater than the depth of the inlet tank 5. After the waste in the inlet tank 5 is scraped by the scraper 14 into the collection tank 7, it eventually sinks down into the collection tray 19.
[0029] like Figure 6 As shown, a vertically extending support column 20 is installed on the top left side of the pool body 1. A horizontally extending cantilever 21 is welded to the upper right side of the support column 20. A winch 22 is bolted to the top of the cantilever 21, and a steel wire rope 23 is wound on the winch 22. Hanging ropes 24 are fixedly connected to the four corners of the collection tray 19, and the ends of the four hanging ropes 24 away from the collection tray 19 are fixedly connected to the free ends of the steel wire ropes 23. When a certain amount of dirt accumulates in the collection tray 19, the collection tray 19 can be lifted upward by winding the steel wire ropes 23 through the winch 22, thereby facilitating the cleaning of the dirt in the collection tray 19.
[0030] In addition, the end of the cantilever 21 away from the support column 20 is integrally formed with two opposing ear plates. A guide wheel 25 with a horizontally extending axis is rotatably installed between the two ear plates. The free end of the wire rope 23 passes downward around the guide wheel 25 and connects to the collection tray 19, thereby improving the smoothness of the lifting and lowering of the wire rope 23.
[0031] The lower end of the support column 20 is rotatably mounted on the drive box 26 via a bearing. The drive box 26 is fixed to the top left side of the pool body 1. An adjustment motor 27 for driving the support column 20 to rotate around its own axis is also mounted on the drive box 26 via bolts. The adjustment motor 27 is connected to the support column 20 through a transmission mechanism such as gears or belts. When the wire rope 23 lifts the collection tray 19 upward, the adjustment motor 27 can drive the support column 20 to rotate. The support column 20 drives the collection tray 19 to deviate from the pool body 1 through the cantilever 21 and the wire rope 23, making it easier to clean the collection tray 19.
[0032] like Figure 4 and Figure 5 As shown, the movable frame 8 is also equipped with a cleaning component for cleaning the water distribution hole 6. The cleaning component includes a cleaning motor 28, the motor shaft of the cleaning motor 28 faces the water inlet tank 5, and a cleaning rod 29 matching the water distribution hole 6 is coaxially fixed on the motor shaft of the cleaning motor 28. The diameter of the cleaning rod 29 is smaller than the diameter of the water distribution hole 6, and the axis of the cleaning rod 29 is parallel to the axis of the water distribution hole 6. The outer side of the cleaning rod 29 is provided with bristles 30. The cleaning motor 28 is driven by a telescopic component and moves in a direction parallel to the axis of the water distribution hole 6.
[0033] Specifically, a guide rail 31 is fixedly installed on the left side of the movable frame 8 by bolts. The guide rail 31 extends along the axis parallel to the water distribution hole 6. A motor housing 32 is slidably installed on the guide rail 31. A sliding seat matching the guide rail 31 is fixedly installed at the bottom of the motor housing 32 by bolts. The cleaning motor 28 is installed inside the motor housing 32 by bolts, and its motor shaft extends out of the outside of the motor housing 32.
[0034] The telescopic component includes a cleaning cylinder 33 that is bolted to the movable frame 8. The piston rod of the cleaning cylinder 33 extends to the left along the axis parallel to the water distribution hole 6. The motor housing 32 is fixedly connected to the piston rod of the cleaning cylinder 33 by bolts.
[0035] During the back-and-forth movement of the movable frame 8, when the movable frame 8 moves the cleaning rod 29 to align with any of the water distribution holes 6, the movable frame 8 first stops moving, and then the cleaning cylinder 33 extends to drive the cleaning motor 28 to approach the water inlet tank 5. The cleaning motor 28 drives the cleaning rod 29 to extend into the water distribution hole 6. At the same time, the cleaning motor 28 drives the cleaning rod 29 to rotate, and then the brush bristles 30 on the cleaning rod 29 clean the inner wall of the water distribution hole 6 to prevent dirt from clogging the water distribution hole 6.
[0036] After cleaning one of the water distribution holes 6, the cleaning cylinder 33 retracts and drives the cleaning motor 28 back to its original position. The cleaning motor 28 drives the cleaning rod 29 to move out of the water distribution hole 6. Then the movable frame 8 continues to move forward or backward. The distance that the movable frame 8 moves each time is consistent with the interval between two adjacent water distribution holes 6, so that the cleaning rod 29 can clean the next water distribution hole 6.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
