Description

Technical Field

[0001] This utility model relates to the field of sludge discharge valve technology, specifically to a sludge discharge valve structure for sedimentation tanks to prevent clogging. Background Technology

[0002] A sludge discharge valve is a filtration device used to remove sludge and impurities settled at the bottom of a sedimentation tank. It is commonly used in urban water plants and sewage treatment plants to discharge sludge from the bottom of sedimentation tanks, facilitating the cleaning of the sludge within the tank. Sewage sedimentation tanks are structures located on the ground that rely on sedimentation to remove suspended solids from sewage, providing a preliminary purification effect. As suspended solids settle, sludge and other impurities gradually accumulate at the bottom of the sedimentation tank. To periodically remove this sludge and impurities from the sedimentation tank, a sludge discharge valve is usually installed outside the tank.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the current process of treating sludge in sedimentation tanks, the sludge discharge valve usually does not separate sludge from wastewater, which easily causes blockage and increases economic costs. Therefore, we propose a sedimentation tank anti-blockage sludge discharge valve structure to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sludge discharge valve structure for sedimentation tanks, which solves the problem that current sludge discharge valves in sedimentation tanks typically lack the ability to separate sludge from wastewater, easily causing blockages and increasing economic costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sedimentation tank anti-clogging sludge discharge valve structure, including a sludge pipe, a diversion pipe installed at the top of the sludge pipe, a filter screen installed on the inner wall of the sludge pipe, a threaded rod threaded into the inner cavity of the diversion pipe, a drain pipe fixedly connected to the right side wall of the diversion pipe, a plug rotatably connected to the bottom end of the threaded rod, and a buffer mechanism provided on the outer wall of the threaded rod;

[0006] A sludge discharge pipe is installed at the bottom of the sludge pipe, and a sludge unloading mechanism is provided at the bottom of the sludge discharge pipe. A motor is fixedly installed at the top of the sludge pipe and on the left side wall of the filter screen, and a screw rod is fixedly connected to the output end of the motor.

[0007] Preferably, the lead screw has drainage pipes running through both its upper and lower ends, the plug is rotatably connected to the bottom of the lead screw, and the drain pipe is located in the middle of the right side wall of the drainage pipe.

[0008] Preferably, the buffer mechanism includes two springs and a piston, with the upper ends of the two springs fixedly connected to the top of the inner wall of the drainage tube, and the piston slidably connected to the inner wall of the drainage tube.

A sludge removal pipe is fixedly connected to the left side wall of the sludge storage box, and a guide plate is fixedly connected to the top of the inner wall of the sludge storage box.

[0012] Preferably, a protective cover is installed on the top of the sludge pipe, the motor is located inside the protective cover, and heat dissipation holes are provided on the side walls of the protective cover.

[0013] Beneficial effects

[0014] This utility model provides a sludge discharge valve structure for sedimentation tanks to prevent clogging. Compared with the prior art, it has the following advantages:

[0015] 1. The anti-clogging sludge discharge valve structure of this sedimentation tank, by rotating the screw, drives the plug to move down, so that the sealing ring and the sealing gasket are separated, and the sludge pipe is connected to the drainage pipe, which allows the sludge to accumulate on the left side of the filter screen. When the motor is started, it drives the screw rod to rotate, and discharges the sludge adhering to the filter screen into the sludge removal mechanism, which can separate the sludge from the sewage, thereby avoiding clogging and reducing economic costs.

[0016] 2. The anti-clogging sludge discharge valve structure of this sedimentation tank, through the buffer mechanism, when the sludge pipe is connected to the diversion pipe, the sewage will rush into the lower part of the buffer mechanism. Under the action of pressure, the buffer mechanism will move up to the upper part of the drainage pipe, so that the diversion pipe and the drainage pipe are connected. At this time, the sewage can be discharged along the drainage pipe, and the buffer mechanism can reduce the impact force of the sewage. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a sedimentation tank anti-clogging sludge discharge valve structure, including a sludge pipe 1, a diversion pipe 2 installed at the top of the sludge pipe 1, a filter screen 9 installed on the inner wall of the sludge pipe 1, a screw rod 7 threadedly connected to the inner cavity of the diversion pipe 2, a drain pipe 4 fixedly connected to the right side wall of the diversion pipe 2, a plug 14 rotatably connected to the bottom end of the screw rod 7, and a buffer mechanism provided on the outer wall of the screw rod 7.

[0024] A sludge discharge pipe 3 is installed at the bottom of the sludge pipe 1. A sludge removal mechanism 5 is provided at the bottom of the sludge discharge pipe 3. A motor 8 is fixedly installed at the top of the sludge pipe 1 and on the left side wall of the filter screen 9. A spiral rod 81 is fixedly connected to the output end of the motor 8. A sealing ring 12 is fixedly connected to the bottom of the drainage pipe 2. A sealing gasket 13 is fixedly installed at the top of the plug 14.

[0025] Through the sludge pipe 1, the drainage pipe 2, the sludge discharge pipe 3, the motor 8 and the filter screen 9 can be installed. Since the output end of the motor 8 is fixedly connected to the screw rod 81, and the inner cavity of the drainage pipe 2 is threaded with the screw rod 7, rotating the screw rod 7 will drive the plug 14 to move down, the sealing ring 12 and the sealing gasket 13 will separate, and the sludge pipe 1 and the drainage pipe 2 will be connected. At this time, the sludge accumulates on the left side of the filter screen 9. The motor 8 is started to drive the screw rod 81 to rotate, and the sludge adhering to the filter screen 9 is discharged into the sludge removal mechanism 5, thereby separating the sludge from the sewage.

[0026] When the sludge pipe 1 is connected to the drainage pipe 2, the sewage will flow into the lower part of the buffer mechanism. Under pressure, the buffer mechanism will move up to the upper part of the drainage pipe 4, so that the drainage pipe 2 and the drainage pipe 4 are connected. At this time, the sewage can be discharged along the drainage pipe 4, and the impact force of the sewage can be reduced by the buffer mechanism.

[0027] See Figure 2Both ends of the lead screw 7 pass through the drain pipe 2, and the plug 14 is rotatably connected to the bottom of the lead screw 7. Meanwhile, the drain pipe 4 is located in the middle of the right side wall of the drain pipe 2.

[0028] The plug 14 can be installed by means of the screw 7, thereby rotating the screw 7 to move the plug 14 down, so that the sealing ring 12 and the sealing gasket 13 are separated. At this time, the sludge pipe 1 and the drainage pipe 2 are connected. The sewage will cause the buffer mechanism to move up to the top of the drain pipe 4. The drainage pipe 2 and the drain pipe 4 are connected, so that the sewage can be discharged from the drain pipe 4.

[0029] See Figure 2 The buffer mechanism includes two springs 10 and a piston 11. The upper ends of the two springs 10 are fixedly connected to the top of the inner wall of the drainage tube 2, and the piston 11 is slidably connected to the inner wall of the drainage tube 2. The lower ends of the two springs 10 are fixedly connected to the top of the piston 11, and the piston 11 is located below the drain tube 4.

[0030] The piston 11 in the buffer mechanism can be used to install two springs 10. Since the upper ends of the two springs 10 are fixedly connected to the top of the inner wall of the drainage pipe 2, and the piston 11 is located below the drain pipe 4, after the sludge pipe 1 is connected to the drainage pipe 2, the sewage will rush into the area below the piston 11. Under pressure, the piston 11 will compress the two springs 10 and move them up to the top of the drain pipe 4, so that the drainage pipe 2 and the drain pipe 4 can be connected. At this time, the sewage can be discharged along the drain pipe 4, and the piston 11 can reduce the impact force of the sewage.

[0031] See Figure 1 , Figure 3 The sludge removal mechanism 5 includes a sludge storage box 51, which is fixedly installed at the bottom of the sludge discharge pipe 3. The sludge storage box 51 is connected to the sludge discharge pipe 3. A sludge removal pipe 52 is fixedly connected to the left side wall of the sludge storage box 51, and a guide plate 53 is fixedly connected to the top of the inner wall of the sludge storage box 51.

[0032] The sludge storage box 51 in the sludge dredging mechanism 5 allows the sludge dredging pipe 52 and the guide plate 53 to be installed. Since the sludge storage box 51 is connected to the sludge discharge pipe 3, the screw rod 81 rotates, discharging the sludge adhering to the filter screen 9 into the sludge storage box 51, which can separate the sludge from the sewage. At this time, the sludge in the sludge storage box 51 can be easily discharged through the sludge dredging pipe 52 and the guide plate 53.

[0033] See Figure 1 , Figure 4 The top of the sludge pipe 1 is equipped with a protective cover 6, the motor 8 is located inside the protective cover 6, and the side walls of the protective cover 6 are provided with heat dissipation holes 61.

[0034] The protective cover 6 can be installed through the sludge pipe 1. Since the motor 8 is located inside the protective cover 6, the protective cover 6 can prevent foreign objects such as metal fragments, wood chips, dust and so on from contacting the rotating parts of the motor 8. Since the side walls of the protective cover 6 are provided with heat dissipation holes 61, air convection can be achieved through the heat dissipation holes 61, forming a natural ventilation circulation, which can extend the service life of the motor 8.

[0035] During operation, the sludge pipe 1 can be used to install the drainage pipe 2, the sludge discharge pipe 3, the motor 8, and the filter screen 9. Since the output end of the motor 8 is fixedly connected to the screw rod 81, and the inner cavity of the drainage pipe 2 is threaded with the screw rod 7, rotating the screw rod 7 will drive the plug 14 to move down, the sealing ring 12 will separate from the sealing gasket 13, and the sludge pipe 1 will be connected to the drainage pipe 2. At this time, the sludge accumulates on the left side of the filter screen 9. The motor 8 is started to drive the screw rod 81 to rotate, and the sludge adhering to the filter screen 9 will be discharged into the sludge removal mechanism 5, thereby separating the sludge from the sewage.

[0036] When the sludge pipe 1 is connected to the drainage pipe 2, the sewage will flow into the lower part of the buffer mechanism. Under pressure, the buffer mechanism will move up to the upper part of the drainage pipe 4, so that the drainage pipe 2 and the drainage pipe 4 are connected. At this time, the sewage can be discharged along the drainage pipe 4, and the impact force of the sewage can be reduced by the buffer mechanism.

[0037] The plug 14 can be installed by means of the screw 7, thereby rotating the screw 7 to move the plug 14 down, so that the sealing ring 12 and the sealing gasket 13 are separated. At this time, the sludge pipe 1 and the drainage pipe 2 are connected. The sewage will cause the buffer mechanism to move up to the top of the drain pipe 4. The drainage pipe 2 and the drain pipe 4 are connected, so that the sewage can be discharged from the drain pipe 4.

[0038] The piston 11 in the buffer mechanism can be used to install two springs 10. Since the upper ends of the two springs 10 are fixedly connected to the top of the inner wall of the drainage pipe 2, and the piston 11 is located below the drain pipe 4, after the sludge pipe 1 is connected to the drainage pipe 2, the sewage will rush into the area below the piston 11. Under pressure, the piston 11 will compress the two springs 10 and move them up to the top of the drain pipe 4, so that the drainage pipe 2 and the drain pipe 4 can be connected. At this time, the sewage can be discharged along the drain pipe 4, and the piston 11 can reduce the impact force of the sewage.

[0039] The sludge storage box 51 in the sludge dredging mechanism 5 allows the sludge dredging pipe 52 and the guide plate 53 to be installed. Since the sludge storage box 51 is connected to the sludge discharge pipe 3, the screw rod 81 rotates, discharging the sludge adhering to the filter screen 9 into the sludge storage box 51, which can separate the sludge from the sewage. At this time, the sludge in the sludge storage box 51 can be easily discharged through the sludge dredging pipe 52 and the guide plate 53.

[0040] The protective cover 6 can be installed through the sludge pipe 1. Since the motor 8 is located inside the protective cover 6, the protective cover 6 can prevent foreign objects such as metal fragments, wood chips, dust and so on from contacting the rotating parts of the motor 8. Since the side walls of the protective cover 6 are provided with heat dissipation holes 61, air convection can be achieved through the heat dissipation holes 61, forming a natural ventilation circulation, which can extend the service life of the motor 8.

[0041] In summary, the device rotates the screw 7 to move the plug 14 downward, causing the sealing ring 12 to separate from the sealing gasket 13, and the sludge pipe 1 to connect with the drainage pipe 2, allowing sludge to accumulate on the left side of the filter screen 9. The motor 8 is started to drive the screw rod 81 to rotate, discharging the sludge adhering to the filter screen 9 into the sludge removal mechanism 5, which can separate and treat the sludge from the sewage.
