Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage treatment sedimentation tank. Background Art

[0002] During the sewage treatment process, sewage is poured into the sedimentation tank, and the suspended matter in the water is removed by the natural sedimentation or coagulation sedimentation of water. The sedimentation tank is divided into horizontal sedimentation tank and vertical sedimentation tank according to the direction of water flow. The treatment effect of the sedimentation tank is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0003] Currently, when treating sewage, the precipitated suspended matter will sink and flow into the sludge trough along the bottom of the pool. During the continuous treatment of sewage, the suspended matter inside the sludge trough continues to increase, and then the operator needs to drain the sewage and clean the sludge trough with a water gun. This not only increases the cost, but also reduces the sewage treatment efficiency. Therefore, a sewage treatment sedimentation tank is proposed to address the above problems. Utility Model Content

The cam is located directly above the mud discharge trough.

[0008] Preferably, the left and right ends of the interactive rod are respectively adapted to contact two two-way switches, and the bottom end of the vertical rod is slidably connected to the groove on the cam surface. When the cam rotates, it pushes the vertical rod to move back and forth in the left and right directions.

[0009] Preferably, the cleaning assembly includes a support rod fixedly mounted on the inner wall of the sedimentation tank body, a slider is provided on the surface of the support rod, an electromagnet is clamped inside the top of the slider, a hollow plate is fixedly mounted on the bottom end of the slider, a rotating push plate is rotatably connected to the inside of the hollow plate, a baffle is fixedly mounted on the rear end of the hollow plate, an inner groove is provided inside the sedimentation tank body, and magnetic blocks are fixedly mounted on the front and rear ends of the support rod.

[0023] The following is combined with Figure 1 —5 provide further details of this application,

[0024] The present application discloses a sewage treatment sedimentation tank. Figure 1 A sewage treatment sedimentation tank comprises a sedimentation tank body 1, a mud discharge trough 2 is provided on the bottom wall of the sedimentation tank body 1, a treatment trough 3 is provided at the front end of the sedimentation tank body 1, a driving component 4 is provided on the bottom wall of the sedimentation tank body 1, and a cleaning component 5 is provided on the bottom wall of the sedimentation tank body 1;

[0025] Reference Figure 1 - Figure 2The driving assembly 4 includes two supporting sleeves 41 fixedly mounted on the left and right sides of the bottom wall of the sedimentation tank body 1. The two supporting sleeves 41 are internally rotatably connected with cams 42. The front end of the mud discharge trough 2 is connected to the processing tank 3, and the suspended matter inside the mud discharge trough 2 can be discharged into the interior of the processing tank 3. The suspended matter inside the processing tank 3 is then discharged with the flow of water. The cam 42 is located just above the mud discharge trough 2. Turbines 43 are fixedly mounted on the left and right sides of the surface of the cam 42. A semi-I-shaped rod 44 is fixedly mounted on the top of the inner wall of the sedimentation tank body 1. Two-way switches 45 are fixedly mounted on the left and right sides of the interior of the semi-I-shaped rod 44. An interactive rod 46 is slidably connected to the interior of the semi-I-shaped rod 44. A vertical rod 47 is fixedly mounted on the bottom of the middle part of the interactive rod 46. The left and right ends of the interactive rod 46 are respectively adapted to contact the two two-way switches 45. The bottom end of the vertical rod 47 is slidably connected to the groove on the surface of the cam 42. When the cam 42 rotates, it pushes the vertical rod 47 to move back and forth in the left and right directions.

[0026] Reference Figure 3 - Figure 5 The cleaning assembly 5 includes a support rod 51 fixedly mounted on the inner wall of the sedimentation tank body 1, a slider 52 is provided on the surface of the support rod 51, an electromagnet 53 is clamped inside the top of the slider 52, a hollow plate 54 is fixedly mounted on the bottom end of the slider 52, a rotating push plate 55 is rotatably connected to the inside of the hollow plate 54, a baffle 56 is fixedly mounted on the rear end of the hollow plate 54, the rotating push plate 55 is adapted to be slidably connected to the inside of the mud discharge trough 2, and the rotating push plate 55 can slide inside the mud discharge trough 2 to remove the suspended matter inside the mud discharge trough 2 To push and clear, the front end of the baffle 56 and the rear end of the rotating push plate 55 are in adaptive contact. The baffle 56 is limited so that the rotating push plate 55 cannot rotate backward. An inner groove 57 is provided inside the sedimentation tank body 1. Magnetic blocks 58 are fixedly installed at the front and rear ends of the support rod 51. The electromagnet 53 is electrically connected to a wire. The other end of the wire passes through the inner groove 57 and is electrically connected to the two-way switch 45. The magnetic poles of the two magnetic blocks 58 at the adjacent ends are the same, and the magnetic pole direction distribution of the electromagnet 53 can be controlled separately by the two two-way switches 45.

[0027] Working principle: After the operator pours sewage into the sedimentation tank body 1, the sewage will gradually settle inside the sedimentation tank body 1. At this time, the settled suspended matter will accumulate inside the sedimentation tank body 1. Then, the settled suspended matter will move to the inside of the mud discharge trough 2 under the force of the sewage flow. In addition, the operator can also drive the mud discharge equipment to push the suspended matter into the mud discharge trough 2. At this time, the suspended matter settled inside the mud discharge trough 2 will gradually increase.

[0028] Afterwards, under the force of sewage flow, the turbine 43 is driven by the water flow to rotate, and the turbine 43 will drive the cam 42 to rotate inside the support sleeve 41. When the cam 42 rotates, the vertical rod 47 is always located in the groove opened on the surface of the cam 42. At this time, the vertical rod 47 moves back and forth left and right under the action of the groove. At this time, the vertical rod 47 will drive the fixed interactive rod 46 to move left and right. At this time, the interactive rod 46 will periodically press the two two-way switches 45 on the left and right sides. At this time, the electromagnetic distribution of the electromagnet 53 electrically connected to the two-way switch 45 changes periodically. Since the magnetic poles of the two magnetic blocks 58 at the proximal ends are the same, they will move periodically left and right under the force of the two magnetic blocks 58 on the electromagnet 53. At this time, the electromagnet 53 will push the slider 52 to slide on the surface of the support rod 51, and when the slider 52 moves, it will drive the hollow plate 54 to move accordingly. When the hollow plate 54 moves forward, at this time The hollow plate 54 will drive the rotating push plate 55 to move accordingly, and the rear end of the rotating push plate 55 contacts the baffle 56, so the rotating push plate 55 will not rotate backward. At this time, the rotating push plate 55 remains vertical due to the resistance of the sewage during the movement. At this time, the rotating push plate 55 pushes the suspended matter inside the sludge discharge trough 2 to move forward, and then the suspended matter is pushed into the interior of the treatment tank 3 by the rotating push plate 55, and then the suspended matter moves to the right under the push of the water flow until it is discharged. When the hollow plate 54 drives the rotating push plate 55 to move backward, the rotating push plate 55 rotates forward under the resistance of the sewage. At this time, the bottom end of the rotating push plate 55 is separated from the bottom wall of the sludge discharge trough 2, so the rotating push plate 55 will not push the suspended matter at the bottom of the sludge discharge trough 2 when moving backward, avoiding pushing the suspended matter back into the rear of the sedimentation tank body 1, and facilitating the rotating push plate 55 to move forward in the next cycle to push the suspended matter to the interior of the treatment tank 3 again.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
