Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an anti-clogging device for wastewater sedimentation tanks. Background Technology

[0002] In various fields such as sewage treatment, tap water production, and industrial wastewater treatment, sedimentation tanks, as core solid-liquid separation equipment, undertake the key task of removing suspended particles, sludge, and other impurities from water bodies. Their operating efficiency directly determines the effectiveness of subsequent treatment processes and the final effluent quality, playing an irreplaceable role in ensuring the recycling of water resources and ecological environment safety.

[0003] Existing sedimentation tanks primarily employ two sludge discharge methods: continuous sludge discharge and traditional intermittent sludge discharge. Continuous sludge discharge involves continuously opening the discharge outlet. In this mode, a large volume of sludge rushes into the outlet at random flow rates. Since the discharge channel has a limited capacity, this instantaneous high-load sludge flow far exceeds the channel's capacity, causing rapid sludge accumulation in the outlet and channel, leading to blockages. Traditional intermittent sludge discharge typically uses fixed valves to control the opening and closing of the discharge outlet. Opening these valves also results in a concentrated discharge of sludge within a short period, easily causing blockages. Once a blockage occurs, the system must be shut down for manual sludge removal, consuming significant manpower and resources, interrupting the entire treatment system, increasing maintenance costs, and raising system operational risks.

[0004] Patent application CN218653118U discloses an anti-clogging structure for a sewage sedimentation tank. The structure includes first sliding grooves on both inner walls of the sedimentation tank body, with push plates movably connected within these grooves. A reciprocating screw is movably connected between the inner walls of the sedimentation tank body and threadedly connected to the push plates. A motor is fixedly connected to one outer wall of the sedimentation tank body, with one end of the motor's output shaft passing through the sedimentation tank body and fixed to the reciprocating screw. A sewage outlet is located on one side of the sedimentation tank body, with a sewage pipe fixedly connected within the outlet.

[0005] However, this patent has the following drawbacks: when the anti-clogging structure discharges sludge, it pushes the sludge in the sedimentation tank toward the discharge outlet at once, and a large amount of sludge will rush into the discharge outlet at once, which can easily cause the discharge outlet to become blocked. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of blockage at the discharge outlet caused by continuous or concentrated sludge discharge from existing sedimentation tanks, which necessitates manual sludge removal and leads to system interruption. This invention provides an anti-blockage device for sewage sedimentation tanks.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An anti-clogging device for a sewage sedimentation tank includes a sedimentation tank body with a sweeping rod slidably installed inside the sedimentation tank body. An anti-clogging structure is provided inside the sedimentation tank body. The anti-clogging structure moves the sweeping rod to gradually push the sludge at the bottom of the sedimentation tank body towards the discharge outlet, so that the sludge is discharged from the discharge outlet in batches.

[0009] Furthermore, the sedimentation tank body is square in shape, and fixed plates are fixedly installed at both ends of the upper surface of the sedimentation tank body. A reciprocating screw is rotatably connected between the fixed plates, and a sliding block is threadedly connected to the reciprocating screw. A push rod is fixedly connected to the lower surface of the sliding block.

[0010] Furthermore, a container is fixedly installed inside the sedimentation tank body. A fixing block is provided on the upper part of the container. Hollow parts are provided on both sides of the container. A first toothed rack is fixedly connected to the lower surface of the hollow part. A connecting rod is fixedly installed at the end of the first toothed rack near the push rod. The first toothed rack meshes with a first gear. The first gear is fixedly connected to a first rotating shaft. The first rotating shaft is fixedly connected to a first bevel gear. The first bevel gear meshes with a second bevel gear. The second bevel gear is fixedly connected to a rotating rod.

[0011] Furthermore, the rotating rod has a first limiting groove and a second limiting groove, and guide rods are provided on both sides of the rotating rod. A spring is provided on the guide rod, and a sliding plate is fixedly connected to the spring. A fixing rod is fixedly connected to the upper surface of the sliding plate, and the fixing rod is fixedly connected to the lower part of the sliding door. A limiting shaft is rotatably provided on the sliding plate, and the limiting shaft passes through the sliding plate and is connected to the rotating rod.

[0012] Furthermore, a hydraulic cylinder is provided inside the fixed block. The output end of the hydraulic cylinder is fixedly connected to a pressure plate, and the pressure plate is fixedly connected to a movable door. The first limiting groove is vertically distributed, and the second limiting groove is arc-shaped around the rotating rod. The first limiting groove and the second limiting groove are connected.

[0013] Furthermore, the sludge from the sedimentation tank is discharged in batches, including the following steps: the connecting rod is driven to move by the push rod, the connecting rod drives the first toothed plate to move, the first toothed plate drives the sliding plate to move upward, and the rising of the sliding plate drives the moving door to move upward synchronously; at the same time, the push rod pushes the sludge into the holding tank, and so on, so that the sludge is discharged in batches from the holding tank to the discharge port.

[0014] Furthermore, the sedimentation tank body is conical in shape, and an internal gear is slidably provided on the upper inner side wall of the sedimentation tank body. Multiple second gears are meshed on the internal gears, and a second tooth row is meshed on the upper part of each second gear. A push rod is fixedly connected to the lower surface of the second tooth row on the opposite side.

[0015] Furthermore, the internal gear is circular in shape, the second gear row slides on the upper surface of the internal gear, and the lower surface of the push rod is provided with a base plate, with a second through hole in the middle of the base plate.

[0016] Furthermore, a turntable is slidably provided on the bottom of the base plate, and a third through hole is provided on one side of the turntable; a second rotating shaft is fixedly connected to the middle of the turntable, and the second rotating shaft is connected to a fourth motor.

[0017] Furthermore, the sludge from the sedimentation tank is discharged in batches, including the following steps:

[0018] S1: The third motor drives the second gear to rotate, the second gear drives the inner gear to rotate and the gear rack to move, the inner gear drives multiple second gears to rotate; the movement of the second gear rack drives the push rod to move the sludge from the bottom outside of the sedimentation tank to the middle.

[0019] S2: The turntable is driven to rotate by the fourth motor, so that the third through hole and the second through hole are connected to each other. The sludge accumulated in the middle falls into the sewage outlet through the second through hole. This cycle is repeated, and the sludge on the bottom plate is discharged in batches.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention establishes a receiving cavity inside the sedimentation tank; sludge is conveyed into the receiving cavity via a push rod to achieve centralized temporary storage of sludge; then the sludge is discharged from the receiving tank to the discharge outlet, avoiding the problem of flow overload caused by a large amount of sludge rushing into the discharge outlet in the continuous sludge discharge mode, significantly reducing the risk of blockage caused by high-concentration sludge accumulation at the discharge outlet; at the same time, it ensures that the sludge deposited in the sedimentation tank is discharged in a timely and orderly manner, improving the operational continuity of the sedimentation tank and extending the overall service life of the equipment.

[0022] 2. This invention utilizes a rotatable turntable inside the sedimentation tank to control the opening and closing of the second and third through holes in the tank. When the turntable rotates to fully align and connect the second and third through holes, the sludge deposited in the sedimentation tank is directed towards the discharge outlet along the through-hole channel under the influence of gravity and fluid potential energy. This allows for the batch and uniform discharge of sludge, effectively avoiding the congestion caused by a sudden influx of large amounts of sludge in traditional discharge methods. It reduces the risk of blockage at the discharge outlet due to sludge accumulation, maintains the effective sedimentation capacity of the sedimentation tank, and reduces the frequency of downtime for sludge removal due to blockage. This lowers the consumption of manpower and resources and the risk of system interruption, significantly improving the operational stability, continuity, and maintenance economy of the sedimentation tank.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see Figure 1-3 As shown, an anti-clogging device for a sewage sedimentation tank includes a sedimentation tank body 1, and an anti-clogging structure is provided inside the sedimentation tank body 1. The anti-clogging structure includes a receiving cavity, a reciprocating screw 103, and a push rod 105.

[0042] The sedimentation tank body 1 is square in shape. Fixed plates 102 are fixedly installed at both ends of the upper surface of the sedimentation tank body 1. A reciprocating screw 103 is rotatably connected between the fixed plates 102. A first motor 101 is fixedly installed on the side of the fixed plate 102 away from the reciprocating screw 103. The first motor 101 provides driving force to the reciprocating screw 103. A sliding block 104 is threadedly connected to the reciprocating screw 103. A push rod 105 is fixedly connected to the lower surface of the sliding block 104. The bottom of the push rod 105 is a straight plate.

[0043] By controlling the movement of push rod 105, push rod 105 causes the sludge at the bottom of sedimentation tank body 1 to accumulate at the discharge port 401; specifically as follows:

[0044] By starting the first motor 101, the first motor 101 controls the reciprocating screw 103 to rotate. The rotation of the reciprocating screw 103 drives the sliding block 104 to move. The movement of the sliding block 104 drives the push rod 105 to move and accumulate the sludge at the bottom of the sedimentation tank body 1 towards the sewage outlet 401.

[0045] The sedimentation tank body 1 has a fixedly installed container 3 inside, which is installed at one end near the sewage outlet 401; a fixing block 2 is fixedly installed on the top of the container 3, and the cross section of the fixing block 2 is inclined to facilitate the accumulation of sludge on the outside of the container 3.

[0046] Please see Figure 3-6As shown, the accommodating box 3 has symmetrical cavities 303 on both sides, and a first through hole 302 in the middle of the accommodating box 3. A first toothed rack 305 is fixedly connected to the lower surface of the cavity 303. A connecting rod 304 is fixedly connected to one end of the first toothed rack 305 near the push rod 105. The connecting rod 304 protrudes through the accommodating cavity and towards the push rod 105. A first gear 306 meshes on the first toothed rack 305. One end of the first rotating shaft 3061 is fixedly connected to the first gear 306. A first bevel gear 307 is fixedly connected to the other end of the first rotating shaft 3061. A second bevel gear 308 meshes on the outer side of the first bevel gear 307. A rotating rod 309 is fixedly connected to the second bevel gear 308.

[0047] The rotating rod 309 is provided with a first limiting groove 3091 and a second limiting groove 3092. The first limiting groove 3091 is vertically distributed, and the second limiting groove 3092 is arc-shaped around the rotating rod 309. The first limiting groove 3091 and the second limiting groove 3092 are connected.

[0048] Symmetrical guide rods 310 are provided on both sides of the rotating rod 309. The guide rods 310 are fixed on the fixed base 3093. A spring 311 is provided on the guide rod 310. One end of the spring 311 is fixed on the fixed base 3093. The other end of the spring 311 is fixedly connected to a sliding plate 312. The sliding plate 312 slides on the guide rod 310. One end of the fixed rod 313 is fixedly connected to the upper surface of the sliding plate 312. The other end of the fixed rod 313 is fixedly connected to the lower two sides of the sliding door 301.

[0049] A limiting shaft 3121 is rotatably provided on the sliding plate 312. The limiting shaft 3121 passes through the sliding plate 312 and is connected to the rotating rod 309. The limiting shaft 3121 is matched with the first limiting groove 3091 and the second limiting groove 3092. As the rotating rod 309 rotates, the limiting shaft 3121 moves within the first limiting groove 3091 and the second limiting groove 3092. The limiting shaft 3121 drives the sliding plate 312 to move within the first limiting groove 3091 and the second limiting groove 3092. The sliding plate 312 drives the moving door 301 to move up and down.

[0050] The push rod 105 drives the connecting rod 304 to move, which in turn moves the first toothed plate 305. The first toothed plate 305 then drives the sliding plate 312 to move upward. The upward movement of the sliding plate 312 causes the moving door 301 to move upward synchronously. At the same time, the push rod 105 pushes the sludge into the container 3. This process is repeated to achieve the goal of discharging the sludge in batches from the container 3 to the discharge port 401, thereby reducing the phenomenon of blockage at the discharge port 401.

[0051] Specifically, the push rod 105 moves towards the container 3. The push rod 105 drives the connecting rod 304 to move away from the push rod 105. The connecting rod 304 drives the first gear 305 to move. The first gear 305 drives the first gear 306 to rotate. The first gear 306 drives the first bevel gear 307 to rotate. The first bevel gear 307 drives the second bevel gear 308 to rotate. The second bevel gear 308 drives the rotating rod 309 to rotate. The rotation of the rotating rod 309 drives the limiting shaft 3121 to move upward in the first limiting groove 3091, thereby driving the moving door 301 to move upward. At this time, the spring 311 is in a stretched state, and the push rod 105 pushes the sludge into the container 3. After the sludge in the container 3 is discharged, the process is repeated to discharge the sludge in the container 3 in batches.

[0052] The fixed block 2 is equipped with a hydraulic cylinder 201. The output end of the hydraulic cylinder 201 is fixedly connected to the pressure plate 202. The lower surface of the pressure plate 202 is fixedly connected to the movable door 301. By controlling the pressure plate 202 downward, the sludge on the inner wall of the accommodating cavity can be squeezed downward to reduce the accumulation. On the other hand, the pressure plate 202 can move the movable plate downward, so that the limiting shaft 3121 moves downward in the second limiting groove 3092. At this time, the spring 311 returns to its initial state and the connecting rod 304 returns to its initial position.

[0053] A drain outlet 401 is fixedly connected to the outer wall of the sedimentation tank body 1 near the receiving cavity. A second motor 4 is fixedly connected to one end of the drain outlet 401. The output end of the second motor 4 passes through the drain outlet 401 and is connected to the stirring shaft 402. Multiple stirring blades 403 are fixedly connected to the stirring shaft 402. The stirring blades 403 are L-shaped. Multiple sets of stirring blades 403 are distributed along the length of the stirring shaft 402. The horizontal and vertical sections of adjacent stirring blades 403 are arranged alternately. This facilitates the discharge of sludge from the drain outlet 401 and prevents blockage of the drain outlet 401.

[0054] Working principle:

[0055] First, the sludge is pushed towards the discharge outlet 401: Specifically, the first motor 101 controls the reciprocating screw 103 to rotate, the reciprocating screw 103 rotates and drives the sliding block 104 to move, the sliding block 104 moves and drives the push rod 105 to move and accumulate the sludge at the bottom of the sedimentation tank body 1 towards the discharge outlet 401.

[0056] Then, the sliding door 301 inside the receiving cavity is opened by the push rod 105, and the sludge is pushed into the receiving box 3 in stages; specifically as follows: the push rod 105 drives the connecting rod 304 to move, the connecting rod 304 drives the first gear row 305 to move, the first gear row 305 drives the first gear 306 to rotate, the first gear 306 drives the first bevel gear 307 to rotate, the first bevel gear 307 drives the second bevel gear 308 to rotate, the second bevel gear 308 drives the rotating rod 309 to rotate, the rotating rod 309 drives the limiting shaft 3121 to move upward in the first limiting groove 3091, and the limiting shaft 3121 drives the sliding plate 312 to slide upward. The sliding plate 312 drives the moving door 301 to move upward; at this time, the spring 311 is in a stretched state, and the push rod 105 pushes the sludge into the accommodating cavity from the first through hole 302; then the push rod 105 moves in the opposite direction, and then the channel between the accommodating cavity and the drain port 401 is opened. Then, by controlling the pressure plate 202 to move downward, the sludge on the inner side wall of the accommodating cavity can be squeezed downward. The pressure plate 202 moves downward, driving the moving plate to move downward; the limiting shaft 3121 moves downward in the second limiting groove 3092. At this time, the spring 311 returns to its initial state, the connecting rod 304 returns to its initial position, and then the sludge in the accommodating cavity is discharged in batches.

[0057] Finally, the second motor 4 drives the stirring shaft 402 to rotate, causing the sludge at the drain outlet 401 to be discharged outwards. By discharging the sludge into the drain outlet 401 in batches, the sludge will not accumulate in the drain outlet 401, greatly reducing the phenomenon of blockage of the drain outlet 401.

[0058] Example 2:

[0059] Please refer to it again. Figure 7-10 As shown, an anti-clogging device for a sewage sedimentation tank includes a sedimentation tank body 1. The sedimentation tank body 1 is provided with an anti-clogging structure, which includes a turntable 602, a second gear 501, and a push rod 105.

[0060] The sedimentation tank body 1 is conical in shape. The upper surface of the sedimentation tank body 1 is provided with a cover 503, and the lower part of the sedimentation tank body 1 is provided with a drain outlet 401. An internal gear 5 is slidably provided on the upper inner side wall of the sedimentation tank body 1. The internal gear 5 is annular in shape, and multiple second gears 501 are meshed on the internal gear 5. The second gears 501 are rotatably located on the lower surface of the cover 503.

[0061] The upper part of the second gear 501 is engaged with the second tooth row 502. The second tooth row 502 is slidably disposed on the upper surface of the internal gear 5. The upper side of the second tooth row 502 is slidably disposed on the lower surface of the cover 503. The lower side of the second tooth row 502 is slidably disposed on the sedimentation tank body 1. One second gear 501 is connected to the third motor 504, and the third motor 504 is fixed on the upper surface of the cover 503.

[0062] Multiple second toothed rows 502 are fixedly connected to push rods 105 on the lower surface of opposite sides. The lower side of the push rods 105 is arc-shaped. The lower surface of the push rods 105 is provided with a base plate 505, which is fixedly installed inside the sedimentation tank body 1. A second through hole 5051 is opened in the middle of the base plate 505.

[0063] The push rod is controlled by the third motor 504 to move from the outside to the middle, pushing the sludge to the second through hole for discharge; specifically as follows: by starting the third motor 504, the third motor 504 drives the second gear 501 to rotate, the second gear 501 drives the inner gear 5 to rotate and the gear row to move, the inner gear 5 drives multiple second gears 501 to rotate; the movement of the second gear row 502 drives the push rod 105 to move the sludge from the bottom outside of the sedimentation tank to the middle.

[0064] A turntable 602 is slidably provided on the bottom of the base plate 505. The turntable 602 is arc-shaped. A third through hole 603 with a larger diameter than the second through hole 5051 is opened on one side of the turntable 602. A second rotating shaft 601 is fixedly connected to the middle of the turntable 602. The second rotating shaft 601 passes through the base plate 505 and the cover 503 and connects to the fourth motor 6.

[0065] The turntable 602 is rotated by the fourth motor 6, which controls the opening and closing of the second through hole 5051 and the third through hole 603 of the bottom plate 505, thereby achieving the batch discharge of sludge; as detailed below:

[0066] By starting the fourth motor 6, the fourth motor 6 drives the second rotating shaft 601 to rotate, and the second rotating shaft 601 drives the turntable 602 to rotate. When the third through hole 603 and the second through hole 5051 are connected, the sludge falls from the second through hole 5051 and the third through hole 603 and is discharged from the sewage outlet 401; thus achieving the effect of discharging sludge in batches.

[0067] Working principle:

[0068] First, by moving the push rod 105, the push rod 105 pushes the sludge on the outer wall towards the middle; specifically as follows: the third motor 504 drives the second gear 501 to rotate, the second gear 501 drives the inner gear 5 to rotate and the gear row to move, the inner gear 5 drives multiple second gears 501 to rotate; the movement of the second gear row 502 drives the push rod 105 to move the sludge from the bottom outer side of the sedimentation tank towards the middle.

[0069] Then, by rotating the turntable 602, the second through hole 5051 and the third through hole 603 are connected, and the sludge is discharged in batches. Specifically, the fourth motor 6 drives the second rotating shaft 601 to rotate, the second rotating shaft 601 drives the turntable 602 to rotate, and the rotation of the turntable 602 connects the third through hole 603 with the second through hole 5051. The sludge in the middle falls from the second through hole 5051 to the sewage outlet 401. This cycle is repeated to discharge the sludge on the bottom plate 505 in batches, reduce the phenomenon of blockage of the sewage outlet 401 of the sedimentation tank, and avoid the interruption of sewage treatment in the sedimentation tank due to blockage, which would force the machine to stop for sludge removal.
