Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and more particularly to an anti-clogging suspended filler intercepting device. Background Art

[0002] MBBR process (moving bed biofilm reactor) is a new type of biofilm reactor. By adding a certain amount of suspended filler into the reactor, the sewage continuously passes through the suspended filler and gradually forms a biofilm on the inner and outer surfaces of the filler. The sewage is purified by the action of microorganisms on the biofilm. The filler moves freely under the action of the swirling and turning of the mixed liquid in the reactor. For aerobic reactors, the filler is moved by aeration; for anaerobic reactors, it is stirred by a machine. However, since the density of the filler is close to that of water, during aeration or stirring, the filler will flow out of the reactor with the water, causing the filler to be lost, and even blocking the pipeline or damaging subsequent equipment.

[0003] In the prior art, a retaining net is generally provided at the outlet of the reactor. However, filamentous debris may be mixed in the sewage, and these filamentous debris may gradually clog the retaining net, resulting in poor water discharge.

[0004] Therefore, how to provide an anti-clogging suspended filler intercepting device that can not only intercept the suspended filler but also clean up the filamentary debris to prevent it from clogging the mesh opening is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a suspended filler intercepting device which can not only intercept the suspended filler but also clean the filamentous debris.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] An anti-clogging suspension filler interception device comprises: a frame, a driving wheel, a driven wheel, a screen-type conveyor belt, a motor for driving the driving wheel to rotate, and a debris removal nozzle;

[0008] The side of the top surface of the frame facing away from the water is higher than the side facing the water, the driving wheel is rotatably connected to the high end of the frame, and the driven wheel is rotatably connected to the low end of the frame, the driving wheel and the driven wheel are arranged in parallel and correspondingly, and rotate along the direction of the water flow;

[0009] The motor is installed at the high end of the frame;

[0010] The screen-type conveyor belt is sleeved on the driving wheel and the driven wheel;

[0011] The mesh conveyor belt is fixedly connected by a plurality of baffles along the conveying direction; the baffles include a connecting plate and an intercepting plate, both of which are mesh structures, one end of the connecting plate is connected to one end of the intercepting plate, and the other end is fixedly connected to the corresponding end of the intercepting plate with the adjacent connecting plate, the other end of the intercepting plate is inclined outward, and the intercepting plate corresponding to the water-facing side is inclined below the horizontal plane;

[0012] One end of the debris removal nozzle is fixed on the high end of the frame and arranged on the backwater side, and the other end is connected with the water pipe or the air pipe.

[0013] Through the above technical scheme, it can be known that compared with the prior art, the present invention discloses a kind of anti-blocking suspended filler intercepting device, which is installed at the outlet of the reactor / biochemical pool, the lower end of the frame is submerged in the water, and the high end is above the horizontal plane, the motor drives the driving wheel to rotate, the driving wheel drives the screen conveyor belt to rotate, the driven wheel follows the action of the screen conveyor belt, the water flows to the outlet through the connecting plate and the intercepting plate of the mesh structure, the suspended filler and the filamentary debris mixed in the water are blocked by the connecting plate and the intercepting plate, the suspended filler slides back into the water along the intercepting plate, the filamentary debris is attached to the connecting plate and the intercepting plate, when the connecting plate and the intercepting plate with the filamentary debris attached are turned to the back side of the water, by spraying water or jetting air, the filamentary debris attached to the connecting plate and the intercepting plate can be cleaned up and dropped outside the reactor / biochemical pool. The present invention can not only intercept the suspended filler and prevent it from being lost, but also remove the filamentary debris in the water to prevent it from clogging the mesh port and affecting the outflow of water.

[0014] According to the present invention, the inclination angle between the line connecting the driving wheel and the driven wheel and the horizontal plane ranges from 50° to 90°.

[0015] The beneficial effect of adopting the above technical solution is that the inclination angle between the connecting line of the driving wheel and the driven wheel and the horizontal plane is too small, and the suspended filler can easily rotate to the side of the water outlet along with the connecting plate.

[0016] According to further aspects of the present invention, the angle between the intercepting plate and the connecting plate is 135°.

[0017] The beneficial effect of adopting the above technical solution is that the suspended filler can more easily slide back into the water along the interception plate.

[0018] According to the present invention, it further includes side baffles and bottom baffles, both of which are mesh structures. The side baffles are installed on both sides of the frame and are arranged perpendicular to the water flow direction. The bottom baffle is installed at the bottom of the frame parallel to the water flow direction, with one end close to the intercepting plate and away from the end of the connecting plate.

[0019] The beneficial effect of adopting the above technical solution is that the side baffles and the bottom baffles can prevent the suspended filler from flowing out from the two sides or the bottom end of the screen conveyor belt to the water outlet.

[0020] According to the present invention, it further comprises an elastic baffle, one end of the elastic baffle is fixedly connected to the bottom baffle, and the other end abuts against the intercepting plate.

[0021] The beneficial effect of adopting the above technical solution is that if the bottom baffle is too close to the interception plate, it is easy to interfere with the interception plate and affect the rotation of the interception plate. Therefore, there will be a certain gap between the bottom baffle and the interception plate. In order to prevent the suspended filler from flowing out of the gap, an elastic baffle is set.

[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] The embodiment of the present invention discloses an anti-clogging suspension filler interception device, such as Figure 1 As shown, the horizontal arrow is the direction of water flow, including: a frame 0, a driving wheel 1, a driven wheel 2, a screen conveyor belt 3, a motor for driving the driving wheel 1 to rotate, and a debris removal nozzle 4;

[0030] The back-to-water side of the top surface of the frame 0 is higher than the front-to-water side, the driving wheel 1 is rotatably connected to the high end of the frame 0, and the driven wheel 2 is rotatably connected to the low end of the frame 0. The driving wheel 1 and the driven wheel 2 are arranged in parallel and correspondingly, and rotate along the direction of the water flow;

[0031] The motor is installed at the high end of frame 0;

[0032] The screen conveyor belt 3 is sleeved on the driving wheel 1 and the driven wheel 2;

[0033] The mesh conveyor belt 3 is fixedly connected by a plurality of baffles 31 along the conveying direction; the baffles 31 include a connecting plate 311 and an intercepting plate 312, both of which are mesh structures, one end of the connecting plate 311 is connected to one end of the intercepting plate 312, and the other end is fixedly connected to the connecting plate 311 adjacent to the connecting plate 311 corresponding to one end of the intercepting plate 312, and the other end of the intercepting plate 312 is inclined outward, and the intercepting plate 312 corresponding to the water-facing side is inclined below the horizontal plane;

[0034] One end of the debris removal nozzle 4 is fixed to the high end of the frame 0 and is arranged on the backwater side, and the other end is connected to the water pipe or the air pipe.

[0035] Advantageously, the connecting plate 311 and the intercepting plate 312 are both made of stainless steel mesh.

[0036] Advantageously, the connection plates 311 may be fixedly connected by welding, bolts, snap connections, etc.

[0037] Advantageously, there may be a plurality of debris removal nozzles 4 .

[0038] Advantageously, a receiving platform or a receiving box can be arranged in the direction where the filamentary debris falls, so that the filamentary debris falls onto the platform or into the receiving box, thereby preventing the filamentary debris from falling into the water.

[0039] Advantageously, the inclination angle between the driving wheel 1 and the driven wheel 2 and the horizontal plane ranges from 50° to 90°. If the inclination angle between the driving wheel 1 and the driven wheel 2 and the horizontal plane is too small, the suspended filler is easy to rotate to the outlet side with the connecting plate 311.

[0040] More advantageously, the angle between the intercepting plate 312 and the connecting plate 311 is 135°, so that the suspended filler can more easily slide along the intercepting plate 312 back into the water.

[0041] According to one embodiment of the present invention, it also includes side baffles and bottom baffles 5, both of which are mesh structures. The side baffles are installed on both sides of the frame 0 and are arranged perpendicular to the water flow direction. The bottom baffle 5 is installed at the bottom of the frame 0 parallel to the water flow direction, and one end is close to the intercepting plate 312 and away from the connecting plate 311. The side baffles and the bottom baffle 5 can prevent the suspended filler from flowing out from the two sides or the bottom of the screen conveyor belt to the water outlet.

[0042] Advantageously, the two side baffles and the bottom baffle 5 extend directly to the wall of the reactor / biochemical pool, and together with the screen conveyor belt 3 form a complete barrier to prevent the suspended filler from flowing out in all directions.

[0043] According to one embodiment of the present invention, it also includes an elastic baffle 6, one end of which is fixedly connected to the bottom baffle 5, and the other end is in contact with the interception plate 312. Because the bottom baffle 5 is too close to the interception plate 312, it is easy to interfere with the interception plate 312 and affect the rotation of the interception plate 312. Therefore, there will be a certain gap between the bottom baffle 5 and the interception plate 312. In order to prevent the suspended filler from flowing out of the gap, the elastic baffle 6 is provided.

[0044] The present invention discloses a suspension filler interception device for preventing clogging, and the working principle is as follows:

[0045] 1. The device is installed at the outlet of the reactor / biochemical pool, with the lower end of the frame 0 submerged in the water and the higher end above the horizontal plane. The width of the mesh conveyor belt is the same as the width of the pool, or two side baffles extending to the walls of the reactor / biochemical pool are set, and the bottom baffle 5 also extends to the walls of the reactor / biochemical pool along both sides, forming a complete barrier together with the mesh conveyor belt 3.

[0046] 2. Start the motor, the motor drives the driving wheel 1 to rotate, the driving wheel 1 drives the mesh conveyor belt 3 to rotate, the driven wheel 2 follows the mesh conveyor belt 3, the water flows to the water outlet through the connecting plate 311 and the intercepting plate 312 of the mesh structure, the suspended filler and filamentary debris mixed in the water are blocked by the connecting plate 311 and the intercepting plate 312, the suspended filler slides back into the water along the intercepting plate 312, and the filamentary debris adheres to the connecting plate 311 and the intercepting plate 312.

[0047] 3. When the connecting plate 311 and the intercepting plate 312 with filamentous debris attached are turned to the backwater side, the filamentous debris falls outside the reactor / biochemical pool or falls onto a specially provided receiving platform or receiving box under the action of water or air spray from the debris removal nozzle 4.
