DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a sedimentation tank for sewage treatment, comprising a sedimentation tank body 1, a controller 2 is connected to one side of the surface of the sedimentation tank body 1, a silt removal mechanism 3 is arranged inside the sedimentation tank body 1, a connecting frame 4 is connected to one side of the surface of the sedimentation tank body 1, a silt removal mechanism 5 is connected to one side of the surface of the sedimentation tank body 1, a filter tank 6 is provided on the surface of the sedimentation tank body 1, a silt removal tank 7 is provided on the surface of the sedimentation tank body 1, and a filter screen 8 is connected to the surface of the connecting frame 4;

[0021] The dredging mechanism 3 includes a motor 301, a mud pump 302, a connecting rod 303, a submersible pump 304, a threaded rod 305, a silt extraction pipe 306, a silt discharge pipe 307, a drainage pipe 308, a slider 309 and a shovel plate 310. The motor 301 is installed on one side of the surface of the sedimentation tank body 1, the surface of the sedimentation tank body 1 is connected to the mud pump 302, the inner side of the sedimentation tank body 1 is connected to the connecting rod 303, the inside of the filter tank 6 is connected to the submersible pump 304, one end of the motor 301 is connected to the threaded rod 305, one end of the mud pump 302 is sealedly connected to the silt extraction pipe 306, the other end of the mud pump 302 is sealedly connected to the silt discharge pipe 307, one end of the submersible pump 304 is sealedly connected to the drainage pipe 308, one end of the threaded rod 305 is threadedly connected to the slider 309, and one side of the surface of the slider 309 is connected to the shovel plate 310. 0. When it is necessary to clean the silt inside the sedimentation tank, the staff first starts the motor 301 through the controller 2 when they observe that there is a lot of silt inside the sedimentation tank. The motor 301 drives the threaded rod 305 to rotate. Since the threaded rod 305 is threadedly connected to the slider 309, and the slider 309 is restricted by two sets of connecting rods 303 to move only in a straight line, the slider 309 drives the shovel plate 310 to move. The shovel plate 310 can shovel the silt on the inner wall of the sedimentation tank and push it to one side of the silt extraction pipe 306. At the same time, the mud pump 302 works, and the mud pump 302 sucks the silt through the silt extraction pipe 306, and then discharges it to the filter screen 8 through the silt discharge pipe 307. After that, the moisture in the silt filters the filter screen 8 into the filter tank 6, and the submersible pump 304 in the filter tank 6 can discharge the filtered water in the filter tank 6 back to the sedimentation tank through the drain pipe 308.

[0022] Furthermore, one end of the connecting rod 303 passes through the slider 309, and two groups of connecting rods 303 are provided. Through the setting of the connecting rod 303 and the slider 309, when in use, the connecting rod 303 is used to guide and limit the movement of the slider 309 to ensure that the slider 309 can stably move in a straight line. The slider 309 moves under the drive of the threaded rod 305, thereby driving the shovel plate 310 to work.

[0023] Furthermore, one end of the motor 301 passes through the sedimentation tank body 1 and is connected to the threaded rod 305, and the motor 301 is electrically connected to the controller 2. Through the setting of the threaded rod 305, when in use, the threaded rod 305 cooperates with the slider 309 to realize the linear movement of the slider 309, thereby facilitating the subsequent slider 309 to drive the shovel plate 310 to shovel the sludge.

[0024] Furthermore, one side of the surface of the shovel plate 310 is in contact with the inner wall of the sedimentation tank body 1, and one end of the sludge extraction pipe 306 is embedded in the interior of the sedimentation tank body 1. Through the arrangement of the sludge extraction pipe 306 and the shovel plate 310, when in use, the sludge in the sedimentation tank can enter the interior of the mud pump 302 through the sludge extraction pipe 306, thereby facilitating the subsequent mud pump 302 to transport the sludge to the sludge discharge pipe 307. The shovel plate 310 is used to shovel the sludge inside the sedimentation tank, thereby facilitating the subsequent sludge extraction pipe 306 to quickly extract the sludge.

[0025] Furthermore, the silt removal mechanism 5 includes an electric telescopic rod 501, a limit groove 502, a pressure sensor 503 and a fixed pressure block 504. The electric telescopic rod 501 is installed on one side of the surface of the sedimentation tank body 1, and a limit groove 502 is provided on the inner side of the connecting frame 4. The pressure sensor 503 is embedded in the connecting frame 4. The surface of the filter screen 8 is connected to a fixed pressure block 504. Through the arrangement of the electric telescopic rod 501, the limit groove 502, the pressure sensor 503 and the fixed pressure block 504, when in use, when silting is performed, a certain value is first set for the pressure sensor 503 through the controller 2, and then the silt is removed. After the mechanism 3 discharges the silt to the surface of the filter 8, due to the gravity of the silt, the filter 8 will drive the fixed pressure block 504 to squeeze the pressure sensor 503 inside the limit groove 502. When there is too much silt on the filter 8, causing the pressure sensor 503 to reach the set value, the pressure sensor 503 will feedback a signal to the controller 2. Then the controller 2 controls the operation in the dredging mechanism 3 to be closed, and at the same time controls the start of the electric telescopic rod 501. Then, one end of the electric telescopic rod 501 is continuously extended and drives the connecting frame 4 and one side of the filter 8 to rotate. At this time, the silt on the filter 8 continuously falls into the inside of the silt discharge tank 7, thereby completing the silt discharge.

[0026] Furthermore, one end of the electric telescopic rod 501 is connected to the connecting frame 4, and two groups of electric telescopic rods 501 are arranged. Through the arrangement of the electric telescopic rod 501, when in use, the electric telescopic rod 501 receives instructions from the controller 2, and drives the connecting frame 4 and the filter screen 8 to rotate through the telescopic action, thereby achieving the purpose of allowing the silt to fall into the silt discharge pool 7.

[0027] Furthermore, the pressure sensor 503 is embedded in the limiting groove 502, one end of the fixed pressure block 504 is embedded in the limiting groove 502, and the pressure sensor 503 is electrically connected to the controller 2. Through the setting of the pressure sensor 503, when in use, the pressure sensor 503 monitors the pressure of the sludge on it in real time, and when the pressure reaches the set value, it feeds back a signal to the controller 2 to trigger a corresponding action.

[0028] Working principle: First, when it is necessary to clean the silt inside the sedimentation tank, when the staff observes that there is a lot of silt inside the sedimentation tank, the staff starts the motor 301 through the controller 2, and the motor 301 drives the threaded rod 305 to rotate. Since the threaded rod 305 is threadedly connected to the slider 309, and the slider 309 is restricted by two sets of connecting rods 303 to only move in a straight line, the slider 309 drives the shovel plate 310 to move, and the shovel plate 310 can shovel the silt on the inner wall of the sedimentation tank and push it to one side of the silt extraction pipe 306. At the same time, the mud pump 302 works, and the mud pump 302 sucks the silt through the silt extraction pipe 306, and then discharges it to the filter screen 8 through the silt discharge pipe 307. After that, the moisture in the silt filters the filter screen 8 into the filter tank 6, and the submersible pump 304 in the filter tank 6 can be discharged through the drain pipe 308. The filtered water in the filter tank 6 is discharged back into the sedimentation tank. When the silt is discharged, a certain value is first set for the pressure sensor 503 through the controller 2. After that, after the silt is discharged to the surface of the filter screen 8 by the silt removal mechanism 3, due to the gravity of the silt, the filter screen 8 will drive the fixed pressure block 504 to squeeze the pressure sensor 503 inside the limiting groove 502. When there is too much silt on the filter screen 8, causing the pressure sensor 503 to reach the set value, the pressure sensor 503 will feedback a signal to the controller 2. Then the controller 2 controls the operation in the silt removal mechanism 3 to be closed, and at the same time controls the start of the electric telescopic rod 501. Then, one end of the electric telescopic rod 501 is continuously extended and drives the connecting frame 4 and one side of the filter screen 8 to rotate. At this time, the silt on the filter screen 8 continuously falls into the interior of the silt removal tank 7, thereby completing the silt discharge.
