[0011] As a further improvement, the driving component is a first electric push rod installed on the top of the tank body, and the telescopic end of the first electric push rod extends downward into the tank body and is fixedly connected to the mesh plate located at the top.

[0012] As a further improvement, a vertically extending guide column is fixedly mounted on the mesh plate located at the bottom, and the multiple mesh plates located above are slidably mounted on the guide column.

[0013] As a further improvement, the water outlet pipe extends vertically, 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 in the tank body, and a baffle for sealing the connecting port is vertically slidably installed in the water outlet pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When backwashing the fiber ball filter material, the first electric push rod is contracted to drive the mesh plate at the top to move upward, and then the intervals between the multi-layer mesh plates are pulled by the wire rope to expand, so that the fiber ball filter material between the mesh plates is dispersed up and down, avoiding the accumulation of multi-layer fiber ball filter materials, and effectively improving the backwashing effect of the fiber ball filter material;

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, a fiber medium filter comprises a cylindrical tank body 1, a water inlet pipe 2 is arranged on the left side of the top of the tank body 1, and a water outlet pipe 3 is arranged at the bottom of the tank body 1. When the device is operating normally, water enters through the water inlet pipe 2 and exits through the water outlet pipe 3, and the wastewater is filtered through the fiber ball filter material in the tank body 1; when the interception amount of the fiber ball filter material exceeds its pollution holding capacity, water enters through the water outlet pipe 3 and exits through the water inlet pipe 2, and the fiber ball filter material is backwashed.

[0030] like Figure 2 As shown, a plurality of mesh plates 4 are vertically spaced apart in the tank body 1, the mesh plates 4 include an inner annular plate 5 and an outer annular plate 6 coaxially arranged on the outer side of the inner annular plate 5, the outer circle of the outer annular plate 6 fits the inner circumferential wall of the tank body 1, and a mesh plate body 7 is welded between the inner annular plate 5 and the outer annular plate 6; a fiber ball filter material 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, and a plurality of steel wire ropes 8 are evenly spaced around the circumference of the outer annular plate 6 to improve the stability of the connection between the 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 mesh plate 4 at the bottom is fixedly mounted on the support plate of the inner wall of the tank body 1 by bolts, and the mesh plate 4 at the top is connected with a driving component for driving its vertical movement.

[0031] Specifically, the driving component is a first electric push rod 9 installed on the top of the tank body 1. Two first electric push rods 9 are arranged opposite to each other on the left and right. The body of the first electric push rod 9 is fixedly installed on the top of the tank body 1 by bolts. The telescopic end of the first electric push rod 9 extends downward into the tank body 1. A connecting plate 10 is welded between the inner annular plate 5 and the outer annular plate 6 of the top 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 mesh plate 4 at the top is driven to move downward by the extension of the first electric push rod 9, so that the multi-layer fiber ball filter material is pressed downward to improve the filtering effect of the wastewater; or when backwashing the fiber ball filter material, the mesh plate 4 at the top is driven to move upward by the contraction of the first electric push rod 9, and then the interval between the multi-layer mesh plates 4 is expanded by pulling the steel wire rope 8, so that the fiber ball filter material between the mesh plates 4 is dispersed up and down, and the multi-layer fiber ball filter material is prevented from piling up together, which effectively improves the backwashing effect of the fiber ball filter material.

[0032] In order to improve the stability of the mesh plate 4 moving up and down on the tank body 1, a vertically extending guide column 11 is welded on the outer ring plate 6 of the mesh plate 4 located at the bottom, and a plurality of guide columns 11 are evenly spaced around the circumference of the outer ring plate 6, and the outer ring plates 6 of the plurality of mesh plates 4 located above are all slidably sleeved on the plurality of guide columns 11.

[0033] 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 in the tank body 1. The rotating rod 12 is coaxially arranged with the tank body 1. The rotating rod 12 is rotatably connected to the top wall of the tank body 1 through a bearing. The power device is specifically a motor 13. A motor bracket is provided on the top of the tank body 1. The motor 13 is installed on the motor bracket through 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 located between two adjacent mesh plates 4. In order to prevent the rotating sleeve 15 from rotating relative to the rotating rod 12, a guide groove 16 extending along its length direction is provided on the outer wall of the rotating rod 12. A convex block 17 matching the guide groove 16 is integrally formed on the inner wall of the rotating sleeve 15. A toggling blade 18 is fixedly mounted on the rotating sleeve 15, and the toggling blade 18 extends radially along the tank body 1. A plurality of toggling blades 18 are evenly spaced around the rotating sleeve 15, and one end of the toggling blade 18 is fixedly connected to the rotating sleeve 15 by a bolt or one end of the toggling blade 18 is clamped on the rotating sleeve 15, so that a damaged toggling blade 18 can be replaced.

[0034] When the fiber ball filter material is backwashed, the motor 13 drives the rotating rod 12 to rotate, and then the rotating rod 12 drives the rotating sleeve 15 to rotate. When the rotating sleeve 15 rotates, the fiber ball filter material between the two layers of mesh plates 4 is stirred by moving the blades 18, thereby further improving the backwashing effect of the fiber ball filter material.

[0035] like Figure 3 and Figure 4As shown, positioning holes 19 for the rotating sleeve 15 to pass through are provided on the multiple mesh plates 4 located below, and the lower end of the rotating sleeve 15 is inserted into the corresponding positioning holes 19; an annular plate 20 is integrally formed on the outer side of the rotating sleeve 15, and a pressing plate 21 is fixedly installed on the top of the inner annular plate 5 of the mesh plate 4 located below, and two pressing plates 21 are symmetrically provided with respect to the rotating rod 12, and limiting grooves 22 are provided on the top of the pressing plate 21 and the inner annular plate 5. The thickness of the limiting groove 22 is slightly larger than the thickness of the annular plate 20, and the annular plate 20 is located in the corresponding limiting groove 22, so that when the mesh plate 4 moves up and down, the rotating sleeve 15 and the shifting blade 18 will be driven to move up and down with it, so that the shifting blade 18 is kept close to the top of the mesh plate 4, and when the shifting blade 18 rotates, the fiber ball filter material accumulated on the mesh plate 4 can be shifted from the bottom, thereby improving the stirring effect of the shifting blade 18 on the fiber ball filter material.

[0036] The stirring blade 18 is a flexible stirring blade, and the stirring blade 18 can be made of rubber or silicone material. On the one hand, it can prevent the fiber ball filter material from being damaged due to excessive stirring force, and on the other hand, it can prevent the fiber ball filter material from crushing the flexible stirring blade 18.

[0037] like Figure 5 As shown, the water outlet pipe 3 extends vertically, 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, and a baffle 25 for blocking the connecting port 24 is vertically slidably installed in the water outlet pipe 3, and the baffle 25 is in a ring shape that fits the inner wall of the water outlet pipe 3.

[0038] In this embodiment, a water inlet and outlet 26 is provided on one side of the lower end of the water outlet pipe 3, and a closing plate 27 is fixedly installed on the lower end of the water outlet pipe 3 by bolts, and a second electric push rod 28 is installed on the bottom of the closing plate 27. The body of the second electric push rod 28 is fixedly installed on the bottom of the closing plate 27 by bolts, and the telescopic end of the second electric push rod 28 extends upward into the water outlet pipe 3. A mounting plate 29 is welded inside the lower end of the closing plate 27, and the telescopic end of the second electric push rod 28 is fixedly connected to the mounting plate 29 by bolts.

[0039] When backwashing the fiber ball filter material, the second electric push rod 28 drives the closing plate 27 to move to the inlet and connecting port 24 and seals the connecting port 24, so that the water used for backwashing the fiber ball filter material enters the outlet pipe 3 through the water inlet and outlet 26 and is injected into the tank body 1 by the water distributor 23; or when filtering wastewater, the first electric push rod 9 drives the closing plate 27 to deviate from the connecting port 24 to open the connecting port 24, so that the wastewater filtered by the fiber ball filter material can efficiently enter the outlet pipe 3 through the connecting port 24 and be discharged through the water inlet and outlet 26.

[0040] The water distributor 23 is in the shape of a hollow cylinder, the upper end of the water outlet pipe 3 is connected to the inner cavity of the water distributor 23, and a plurality of water outlet holes 30 are evenly distributed on the outer wall of the water distributor 23. In the present embodiment, the water outlet holes 30 extend along the tangential direction of the water distributor 23, so that the backwash water in the water distributor 23 can generate a vortex when it is injected into the tank body 1 through the water outlet holes 30, thereby improving the flushing effect on the fiber ball filter material.
