Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank anti-clogging technology, and in particular to a sedimentation tank with anti-clogging function. Background Technology

[0002] Sedimentation tanks are water treatment structures that utilize gravity to allow suspended solid particles in water to settle, thus achieving solid-liquid separation. They remove suspended solids such as silt, clay, algae, bacteria, and some organic matter, reducing turbidity and providing better influent conditions for subsequent water treatment processes. Through gravity, suspended solids in wastewater, such as silt, dust, fibers, and biological residues, settle to the bottom of the tank, effectively reducing turbidity. After sedimentation, the suspended solids content in the wastewater is significantly reduced, lessening the processing load on subsequent biological treatment and filtration units. Taking the activated sludge process as an example, reduced suspended solids entering the aeration tank allow microorganisms to better contact organic pollutants, improving treatment efficiency. It also reduces sludge discharge from the aeration tank, lowering sludge treatment costs. Since suspended solids in wastewater often adsorb some organic matter, sedimentation tanks remove a certain amount of organic matter along with suspended solids. Generally, primary sedimentation tanks can remove 20%-30% of organic matter from wastewater. This helps reduce the organic load on subsequent treatment processes and improves the overall wastewater treatment system's organic matter removal efficiency. Sedimentation removes some recalcitrant organic matter and suspended solids from the wastewater, relatively increasing the proportion of readily biodegradable organic matter, thus improving the wastewater's biodegradability. This is beneficial for the growth and metabolism of microorganisms in subsequent biological treatment processes, enhancing the effectiveness of biological treatment. Under gravity, the sludge at the bottom of the sedimentation tank gradually thickens, squeezing out water and reducing its moisture content and volume. This facilitates subsequent sludge treatment and disposal, such as dewatering, transportation, and landfilling, reducing the difficulty and cost of sludge treatment.

[0003] In existing technologies, when treating wastewater through a sedimentation tank, the tank is filled with wastewater, which is then allowed to settle. After settling, the water and sludge are separated and discharged, thus performing preliminary treatment of the wastewater and facilitating subsequent treatment.

[0004] However, existing sludge tends to accumulate in the sludge discharge pipes during discharge, causing blockages and hindering normal sludge discharge. This requires unblocking to ensure proper sludge discharge, thus affecting the efficiency of sludge discharge. Utility Model Content

[0005] The purpose of this invention is to provide a sedimentation tank with anti-clogging function, which solves the problem in the prior art that sludge easily accumulates in the sludge discharge pipe, causing pipe blockage and affecting the efficiency of sludge discharge.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sedimentation tank with anti-clogging function includes a sedimentation tank and a discharge pipe. Two triangular guide blocks are fixedly connected inside the sedimentation tank. The discharge pipe is located between the two guide blocks. An L-shaped barrier net is installed between the two guide blocks through an installation mechanism. A helical blade shaft is rotatably connected inside the discharge pipe. A driving mechanism is provided between the helical blade shaft and the side of the sedimentation tank. The bottom surface of the sedimentation tank slopes downward toward the discharge pipe.

[0008] Preferably, the installation mechanism includes a limiting groove opened at the top of the sedimentation tank, an L-shaped limiting plate slidably connected inside the limiting groove, and one side of the limiting plate being fixedly connected to the top of the barrier net.

[0009] Preferably, anti-fall plates are fixedly connected to both sides of the barrier net.

[0010] Preferably, the drive mechanism includes an L-shaped auxiliary plate fixedly connected to the side of the sedimentation tank, a motor fixedly connected to the surface of the auxiliary plate, a drive gear driven by the output shaft of the motor, a force-bearing gear rotatably connected to the surface of the discharge pipe, the drive gear meshing with the force-bearing gear, and several transmission rods fixedly connected between the force-bearing gear and the spiral blade shaft.

[0011] Preferably, two limiting rings are fixedly connected to the surface of the discharge pipe, and the force-bearing gear is located between the two limiting rings.

[0012] Preferably, a water storage tank is fixedly connected to the top of the sedimentation tank, and a T-shaped water spray head is connected to the surface of the water storage tank.

[0013] This utility model has the following beneficial effects:

[0014] After the wastewater undergoes sedimentation treatment, the sludge is discharged. During discharge, the motor is started first, which drives the spiral blade shaft to rotate. The spiral blade shaft rotates inside the discharge pipe, facilitating the spiral discharge of the sludge. Then, a barrier net is used to block large debris, preventing it from clogging the discharge pipe. This ensures smooth sludge discharge and improves the efficiency of sludge discharge.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A sedimentation tank with anti-clogging function includes a sedimentation tank 1 and a discharge pipe 2. When using the sedimentation tank 1 for sewage treatment, sewage is first poured into the sedimentation tank 1, then the sewage settles. After sedimentation, the water above is pumped out, and then the discharge pipe 2 is opened to discharge the sludge and debris, cleaning the bottom of the sedimentation tank 1, thus completing the sewage treatment. Two triangular guide blocks 3 are fixedly connected inside the sedimentation tank 1. When sludge needs to be discharged, the guide blocks 3 guide the sludge into the discharge pipe 2 for discharge. The discharge pipe 2 is located between the two guide blocks 3, facilitating the discharge of the guided sludge. An L-shaped barrier net 5 is installed between the two guide blocks 3 via an installation mechanism 4. During sludge discharge, the barrier net 5 blocks larger debris, preventing it from entering the discharge pipe 2. Blockage inside the discharge pipe 2 affects the efficiency of sludge discharge. After the sludge discharge is completed, the barrier net 5 is lifted by the installation mechanism 4 to remove the debris on the barrier net 5, thus facilitating the normal discharge and cleaning of the sludge. The discharge pipe 2 is rotatably connected to a spiral blade shaft 6. A drive mechanism 7 is provided between the spiral blade shaft 6 and the side of the sedimentation tank 1. When sludge needs to be discharged through the discharge pipe 2, the drive mechanism 7 can be activated, and then the spiral blade shaft 6 will be rotated through the drive mechanism 7. When the spiral blade shaft 6 moves inside the discharge pipe 2, it can drive the sludge to spiral and rotate inside the discharge pipe 2 and then be discharged, so that the sludge will not be blocked inside the discharge pipe 2, ensuring the smooth discharge of sludge. The bottom surface of the sedimentation tank 1 is inclined downward towards the discharge pipe 2. When the sludge is discharged, it can move and be discharged through the inclined bottom surface of the sedimentation tank 1, which facilitates the movement of sludge inside the sedimentation tank 1 and improves the convenience of sludge discharge.

[0024] Furthermore, the installation mechanism 4 includes a limiting groove 401 opened at the top of the sedimentation tank 1. An L-shaped limiting plate 402 is slidably connected inside the limiting groove 401. One side of the limiting plate 402 is fixedly connected to the top of the barrier net 5. When it is necessary to move the barrier net 5 to remove the debris on the barrier net 5, the limiting plate 402 can be used to apply force to the barrier net 5, so that the barrier net 5 can be moved and removed easily, thereby removing the debris on the barrier net 5. During the process of using the barrier net 5 to intercept debris, the limiting plate 402 can be moved in the limiting groove 401 to move the barrier net 5, thereby moving the debris on the barrier net 5 as well, preventing too much debris from blocking the inlet of the discharge pipe 2 and affecting the efficiency of sludge entering the discharge pipe 2.

[0025] Furthermore, anti-fall plates 403 are fixedly connected to both sides of the barrier net 5. Before the barrier net 5 needs to be lifted upward to move the debris, the anti-fall plates 403 can block the sides of the debris to prevent the debris from falling during the process of the barrier net 5 rising, thus ensuring the stability of the debris when it is taken out.

[0026] Furthermore, the drive mechanism 7 includes an L-shaped auxiliary plate 701 fixedly connected to the side of the sedimentation tank 1. A motor 702 is fixedly connected to the surface of the auxiliary plate 701. The output shaft of the motor 702 is driven by a drive gear 703. A force-bearing gear 704 is rotatably connected to the surface of the discharge pipe 2. The drive gear 703 meshes with the force-bearing gear 704. Several transmission rods 705 are fixedly connected between the force-bearing gear 704 and the spiral blade shaft 6. When it is necessary to rotate the spiral blade shaft 6, the motor 702 on the auxiliary plate 701 can be started first. After the motor 702 rotates, it can drive the drive gear 703 to rotate. The rotation of the drive gear 703 can drive the force-bearing gear 704 meshing with it to rotate. The force-bearing gear 704 rotates on the surface of the discharge pipe 2, and then drives the transmission rods 705 to rotate synchronously with the force-bearing gear 704. The transmission rods 705 transmit the rotation of the force-bearing gear 704 to the spiral blade shaft 6, so that the spiral blade shaft 6 rotates inside the discharge pipe 2 to discharge the sludge.

[0027] Furthermore, two limiting rings 706 are fixedly connected to the surface of the discharge pipe 2, and the force-bearing gear 704 is located between the two limiting rings 706. During the rotation of the force-bearing gear 704, the limiting rings 706 can conveniently limit the force-bearing gear 704, preventing the force-bearing gear 704 from disengaging from the discharge pipe 2 during the rotation, ensuring that the position of the force-bearing gear 704 is fixed and will not affect the rotation of the spiral blade shaft 6.

[0028] Furthermore, a water storage tank 8 is fixedly connected to the top of the sedimentation tank 1. A T-shaped water spray head 9 is connected to the surface of the water storage tank 8. When discharging sludge, the water storage tank 8 can be opened, and water can be conveniently sent to the bottom of the sedimentation tank 1 through the water spray head 9, which facilitates the final cleaning of the sludge and makes the sludge discharge effect better.

[0029] In summary:

[0030] When treating wastewater through sedimentation tank 1, the discharge pipe 2 is first blocked, and then the wastewater is discharged into sedimentation tank 1. The wastewater is then allowed to settle. After sedimentation, the water above is sucked away through a pipe. Next, the barrier net 5 is placed inside sedimentation tank 1, allowing the limiting plate 402 to enter the limiting trough 401. Then, the discharge pipe 2 is opened, and sludge moves towards it via an inclined surface. Guide blocks 3 allow the sludge to enter the discharge pipe 2. The barrier net 5 blocks larger debris from entering the discharge pipe 2. Then, the motor 702 on the auxiliary plate 701 is started. The motor 702 drives the force-bearing gear 704 via the drive gear 703, which in turn drives the spiral blade shaft 6 via the transmission rod 705. As the force-bearing gear 704 rotates on the surface of the discharge pipe 2, it is protected by the limit ring 706. The rotating position is ensured, thereby stably driving the spiral blade shaft 6 to rotate. During the rotation of the spiral blade shaft 6 inside the discharge pipe 2, the sludge entering the discharge pipe 2 can be spirally discharged without blockage. When a lot of debris blocks the inlet of the discharge pipe 2, the limiting plate 402 can be lifted upward to move the barrier net 5. With the help of the anti-fall plate 403, the debris on the barrier net 5 can be removed and disposed of. Then the barrier net 5 can be put back to continue discharging sludge. After all the sludge is discharged, the water storage tank 8 is opened, and the water sprayed by the water nozzle 9 cleans the bottom of the sedimentation tank 1, discharging all the sludge remaining at the bottom of the sedimentation tank 1. Then the next sewage treatment continues. Through the above structure, during the sedimentation treatment of sewage, the settled sludge can be easily discharged without blockage, which would reduce the sludge discharge efficiency. This ensures the efficiency of sludge discharge and makes the sedimentation treatment of sewage more efficient.
