A fiber media filter

Abstract

This invention relates to the field of filtration equipment, specifically to a fiber media filter. The tank contains multiple vertically spaced mesh panels, with fiber ball filter media positioned between adjacent mesh panels. A steel wire rope connects adjacent mesh panels. The bottom mesh panel is fixedly installed inside the tank, while the top mesh panel is connected to a drive component for vertical movement. The tank contains a rotating rod driven by a power unit and rotating around its own axis. The rotating rod vertically penetrates the multiple mesh panels. A rotating sleeve is vertically slidably mounted on the rotating rod between adjacent mesh panels, and actuating blades are fixedly mounted on the rotating sleeve. During backwashing of the fiber ball filter media, a first electric push rod retracts, causing the top mesh panel to move upwards. This, in turn, pulls the steel wire rope to widen the spacing between the multiple mesh panels, dispersing the fiber ball filter media between the mesh panels and preventing the multiple layers of fiber ball filter media from accumulating together.

Description

Technical Field

[0001] This invention relates to the field of filtration equipment, and more specifically to a fiber media filter. Background Technology

[0002] Fiber ball filters use fiber balls or modified fiber balls as filter media. Fiber ball filter media is made of bundled fiber filaments. Compared with traditional rigid granular filter media, it has advantages such as good elasticity, does not float on the water surface, large pores, long working cycle, and low head loss.

[0003] In the prior art, the invention patent with application number CN202380010190.2 discloses a fiber ball filter, including a filter tank, a support filter plate, a double-layer pressing plate assembly, a lifting control assembly, a rotation control assembly, and a fiber ball filter element;

[0004] The support filter plate and the double-layer pressing plate assembly are arranged sequentially from bottom to top inside the filter tank; the fiber ball filter element is arranged in the area between the support filter plate and the double-layer pressing plate assembly inside the filter tank; the lifting control assembly is connected to the double-layer pressing plate assembly.

[0005] The aforementioned fiber ball filter uses a lifting control assembly to control the double-layer pressing plate assembly to move up or down, switching between the working position and the flushing position. However, since the aforementioned fiber media filter only has one layer of support filter plate, the fiber ball filter media on top of the support filter plate tends to accumulate during backwashing, resulting in poor backwashing effect. Summary of the Invention

[0006] The purpose of this invention is to provide a fiber media filter that, by setting up multiple layers of mesh plates, disperses the fiber ball filter media during backwashing, thereby solving the defects mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A fiber media filter includes a tank, with an inlet pipe on one side of the top of the tank and an outlet pipe at the bottom of the tank. The tank contains multiple vertically spaced mesh plates, with fiber ball filter media between adjacent mesh plates. A steel wire rope connects adjacent mesh plates. The bottom mesh plate is fixedly installed inside the tank, and the top mesh plate is connected to a driving component for vertical movement. The tank also contains a rotating rod driven by a power device and rotating around its own axis. The rotating rod vertically passes through the multiple mesh plates, and a rotating sleeve is vertically slidably installed on the rotating rod between adjacent mesh plates. A deflecting blade is fixedly installed on the rotating sleeve.

[0009] As a further improvement, the outer wall of the rotating rod is provided with a guide groove extending along its length, and the inner wall of the rotating sleeve is provided with a protrusion that matches the guide groove.

[0010] As a further improvement, the lower mesh plates are provided with positioning holes for the rotating sleeve to pass through, and the lower end of the rotating sleeve passes through the corresponding positioning holes; an annular plate is provided on the outer side of the rotating sleeve, and a pressure plate is fixedly installed on the top of the mesh plates. A limiting groove is provided between the pressure plate and the mesh plates, and the annular plate is located in the corresponding limiting groove.

[0011] As a further improvement, the actuating blade is a flexible actuating blade.

[0012] As a further improvement, the driving component is a first electric push rod installed on the top of the tank, the telescopic end of the first electric push rod extending downward into the tank and fixedly connected to the mesh plate located at the top.

[0013] As a further improvement, a vertically extending guide post is fixedly installed on the bottommost mesh plate, and multiple mesh plates above are slidably sleeved on the guide post.

[0014] As a further improvement, the water outlet pipe extends vertically, and the upper end of the water outlet pipe extends into the tank body and is fixedly installed with a water distributor. A connecting port is provided on the side wall of the water outlet pipe located inside the tank body, and a baffle for blocking the connecting port is vertically slidably installed inside the water outlet pipe.

[0015] As a further improvement, the lower end of the water outlet pipe is provided with an inlet and outlet, and a sealing plate is fixedly installed at the lower end of the water outlet pipe. A second electric push rod is installed at the bottom of the sealing plate, and the telescopic end of the second electric push rod extends upward into the water outlet pipe and is fixedly connected to the baffle.

[0016] As a further improvement, the water distributor is a hollow cylinder, the upper end of the water outlet pipe is connected to the inner cavity of the water distributor, and multiple water outlet holes are evenly distributed on the outer wall of the water distributor.

[0017] As a further improvement, the water outlet extends along the tangential direction of the water distributor.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When backwashing the fiber ball filter media, the first electric push rod retracts to move the topmost mesh plate upwards, which in turn pulls the steel wire rope to widen the gap between the multiple mesh plates, so that the fiber ball filter media between the mesh plates are dispersed vertically, avoiding the accumulation of multiple layers of fiber ball filter media, and effectively improving the backwashing effect of the fiber ball filter media.

[0020] 2. When backwashing the fiber ball filter media, the motor drives the rotating rod to rotate, which in turn drives the rotating sleeve to rotate. When the rotating sleeve rotates, it agitates the fiber ball filter media between the two layers of mesh by moving the blades, thereby further improving the backwashing effect of the fiber ball filter media.

[0021] 3. When backwashing the fiber ball filter media, the connection port is blocked by the sealing plate, so that the water used for backwashing the fiber ball filter media is injected into the tank through the water distributor and generates a swirling flow, thereby improving the flushing effect on the fiber ball filter media; or when filtering wastewater, the connection port is opened so that the filtered wastewater can be discharged efficiently through the connection port.

Detailed Implementation

[0029] 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.

[0030] like Figures 1 to 5 As shown, a fiber media filter includes a cylindrical tank 1, with an inlet pipe 2 on the top left side of the tank 1 and an outlet pipe 3 at the bottom of the tank 1. During normal operation, water enters through the inlet pipe 2 and exits through the outlet pipe 3, filtering wastewater through the fiber ball filter media inside the tank 1. When the dirt-holding capacity of the fiber ball filter media exceeds its dirt-holding capacity, water enters through the outlet pipe 3 and exits through the inlet pipe 2, backwashing the fiber ball filter media.

[0031] like Figure 2 As shown, the tank body 1 is provided with multiple vertically spaced mesh plates 4. Each mesh plate 4 includes an inner annular plate 5 and an outer annular plate 6 coaxially arranged outside the inner annular plate 5. The outer ring of the outer annular plate 6 is fitted against the inner circumferential wall of the tank body 1. A mesh plate body 7 is welded between the inner annular plate 5 and the outer annular plate 6. Fiber ball filter media is provided between two adjacent mesh plates 4. A steel wire rope 8 is connected between the outer annular plates 6 of two adjacent mesh plates 4. Multiple steel wire ropes 8 are evenly spaced around the circumference of the outer annular plate 6 to improve the stability of the connection between two adjacent mesh plates 4. An annular support plate is welded on the inner circumferential wall of the tank body 1. The outer annular plate 6 of the bottom mesh plate 4 is fixedly installed on the support plate on the inner wall of the tank body 1 by bolts. The top mesh plate 4 is connected to a drive component for driving its vertical movement.

[0032] Specifically, the driving component is a first electric push rod 9 installed on the top of the tank 1. Two first electric push rods 9 are arranged opposite each other on the left and right sides. The body of the first electric push rod 9 is fixedly installed on the top of the tank 1 by bolts. The telescopic end of the first electric push rod 9 extends downward into the tank 1. A connecting plate 10 is also welded between the inner annular plate 5 and the outer annular plate 6 of the topmost mesh plate 4. The telescopic end of the first electric push rod 9 is fixedly connected to the connecting plate 10 by bolts. When filtering wastewater, the extension of the first electric push rod 9 drives the topmost mesh plate 4 to move downward, thereby pressing the multi-layer fiber ball filter media downward to improve the filtration effect of wastewater. Alternatively, when backwashing the fiber ball filter media, the retraction of the first electric push rod 9 drives the topmost mesh plate 4 to move upward, thereby pulling the spacing between the multi-layer mesh plates 4 through the wire rope 8 to disperse the fiber ball filter media between the mesh plates 4, preventing the multi-layer fiber ball filter media from accumulating together and effectively improving the backwashing effect of the fiber ball filter media.

[0033] To improve the stability of the mesh plate 4 moving up and down in the tank 1, a vertically extending guide post 11 is welded on the outer annular plate 6 of the bottom mesh plate 4, and multiple guide posts 11 are evenly spaced around the circumference of the outer annular plate 6. The outer annular plates 6 of the multiple mesh plates 4 located above are all slidably sleeved on the multiple guide posts 11.

[0034] like Figure 2 and Figure 4 As shown, a rotating rod 12 driven by a power device and rotating around its own axis is provided inside the tank body 1. The rotating rod 12 is coaxially arranged with the tank body 1 and is rotatably connected to the top wall of the tank body 1 through a bearing. The power device is a motor 13. A motor bracket is provided on the top of the tank body 1, and the motor 13 is mounted on the motor bracket by bolts. The upper end of the rotating rod 12 is connected to the rotating shaft of the motor 13 through a coupling. The rotating rod 12 vertically penetrates multiple mesh plates 4. The inner annular plate 5 of the top mesh plate 4 is provided with a through hole 14 for the rotating rod 12 to pass through. A rotating sleeve 15 is vertically slidably installed on the rotating rod 12 between two adjacent mesh plates 4. In order to prevent relative rotation between the rotating sleeve 15 and the rotating rod 12, a guide groove 16 extending along its length is provided on the outer wall of the rotating rod 12. A protrusion 17 matching the guide groove 16 is integrally formed on the inner wall of the rotating sleeve 15. A toggle blade 18 is fixedly installed on the rotating sleeve 15. The toggle blade 18 extends radially along the tank body 1. Several toggle blades 18 are evenly spaced around the rotating sleeve 15. One end of the toggle blade 18 is fixedly connected to the rotating sleeve 15 by bolts or one end of the toggle blade 18 is snapped onto the rotating sleeve 15 so that damaged toggle blades 18 can be replaced.

[0035] When backwashing the fiber ball filter media, the motor 13 drives the rotating rod 12 to rotate, which in turn drives the rotating sleeve 15 to rotate. When the rotating sleeve 15 rotates, it agitates the fiber ball filter media between the two mesh plates 4 by moving the blades 18, thereby further improving the backwashing effect of the fiber ball filter media.

[0036] like Figure 3 and Figure 4As shown, the lower mesh plates 4 are provided with positioning holes 19 for the rotating sleeve 15 to pass through, and the lower end of the rotating sleeve 15 passes through the corresponding positioning hole 19. The outer side of the rotating sleeve 15 is integrally formed with an annular plate 20. The top of the inner annular plate 5 of the lower mesh plate 4 is fixedly installed with a pressure plate 21. Two pressure plates 21 are symmetrically arranged relative to the rotating rod 12. The top of the pressure plate 21 and the inner annular plate 5 are provided with a limiting groove 22. The thickness of the limiting groove 22 is slightly greater than the thickness of the annular plate 20. The annular plate 20 is located in the corresponding limiting groove 22. Thus, when the mesh plate 4 moves up and down, it will drive the rotating sleeve 15 and the agitating blade 18 to move up and down with it, so that the agitating blade 18 is kept close to the top of the mesh plate 4. When the agitating blade 18 rotates, it can agitate the fiber ball filter material accumulated on the mesh plate 4 from the bottom, thereby improving the stirring effect of the agitating blade 18 on the fiber ball filter material.

[0037] The agitator blade 18 is a flexible agitator blade. The agitator blade 18 can be made of rubber or silicone. On the one hand, it can avoid damage to the fiber ball filter media due to excessive stirring force, and on the other hand, it can prevent the fiber ball filter media from crushing the flexible agitator blade 18.

[0038] like Figure 5 As shown, the water outlet pipe 3 extends vertically, and the upper end of the water outlet pipe 3 extends into the tank body 1 and is welded with a water distributor 23. A connecting port 24 is provided on the side wall of the water outlet pipe 3 located in the tank body 1. A baffle 25 for blocking the connecting port 24 is vertically slidably installed inside the water outlet pipe 3. The baffle 25 is annular and fits against the inner wall of the water outlet pipe 3.

[0039] In this embodiment, an inlet / outlet 26 is provided on one side of the lower end of the water outlet pipe 3. A sealing plate 27 is fixedly installed on the lower end of the water outlet pipe 3 by bolts. A second electric push rod 28 is installed on the bottom of the sealing plate 27. The body of the second electric push rod 28 is fixedly installed on the bottom of the sealing plate 27 by bolts. The telescopic end of the second electric push rod 28 extends upward into the water outlet pipe 3. An mounting plate 29 is welded inside the lower end of the sealing plate 27. The telescopic end of the second electric push rod 28 is fixedly connected to the mounting plate 29 by bolts.

[0040] When backwashing the fiber ball filter media, the second electric push rod 28 drives the sealing plate 27 to move to the inlet port 24 and seals the port 24. The water used for backwashing the fiber ball filter media then enters the outlet pipe 3 through the inlet and outlet ports 26 and is injected into the tank 1 by the water distributor 23. Alternatively, when filtering wastewater, the first electric push rod 9 drives the sealing plate 27 away from the inlet port 24 to open the port 24. The wastewater filtered by the fiber ball filter media can then efficiently enter the outlet pipe 3 through the inlet port 24 and be discharged through the inlet and outlet ports 26.

[0041] The water distributor 23 is a hollow cylinder. The upper end of the water outlet pipe 3 is connected to the inner cavity of the water distributor 23. Multiple water outlet holes 30 are evenly distributed on the outer wall of the water distributor 23. In this embodiment, the water outlet holes 30 extend along the tangential direction of the water distributor 23. This allows the backwash water in the water distributor 23 to generate a swirling flow when injected into the tank 1 through the water outlet holes 30, thereby improving the flushing effect on the fiber ball filter media.

[0042] 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.
