Technical Field

[0001] The utility model relates to the technical field of water treatment facilities, in particular to a mud retaining device for a horizontal flow sedimentation tank. Background Art

[0002] As an advanced wastewater treatment technology, the horizontal flow sedimentation tank plays an important role in water treatment in water purification plants. The working principle of the horizontal flow sedimentation tank is that the raw water to which the coagulant has been added flows slowly and evenly in the horizontal direction, and the larger suspended matter sinks to the bottom to form a sludge layer, while the clean water rises and flows out from the central water collection area, achieving the effect of solid-liquid separation, removing suspended matter and solid particles in the sewage, and making the wastewater meet the discharge standards. It is widely used in sewage treatment, industrial wastewater treatment, rainwater collection and reuse, etc. For example, the coagulation reaction inclined tube horizontal flow sedimentation tank with the application number of "CN201821532701.X", the utility model discloses A coagulation reaction type inclined tube horizontal flow sedimentation tank has been developed, comprising a coagulation reaction mechanism and a horizontal flow sedimentation tank connected to the coagulation reaction mechanism. The coagulation reaction mechanism comprises a tank body, and weir plates are used in the tank body to divide the tank body into a grid-like structure. The longitudinal weir plates of the tank body are arranged at the ends to cross the water, so that the water flows in an S shape through the coagulation reaction structure. The two adjacent transverse weir plates of the tank body are staggered up and down, so that the water flows from above or below the transverse weir plates; the horizontal flow sedimentation tank comprises a sedimentation tank body, a water outlet and a mud collecting hopper. The water outlet of the coagulation reaction mechanism is connected to the top of the horizontal flow sedimentation tank, and an inclined tube or inclined plate is installed in the horizontal flow sedimentation tank body. The coagulation reaction type inclined tube horizontal flow sedimentation tank of the utility model combines a coagulation reaction tank with a horizontal flow sedimentation tank, so that the sedimentation effect of the horizontal flow sedimentation is better, and the sedimentation efficiency can be effectively improved during operation. The inclined tube horizontal flow sedimentation tank has a processing capacity 3-5 times that of the horizontal flow sedimentation tank.

[0003] However, when this facility is purifying sewage, the bottom sludge in the horizontal flow sedimentation tank will enter the front end of the inclined tube sedimentation tank from its end, causing a large amount of sludge to be deposited at the front end of the inclined tube sedimentation tank, resulting in a large load on the subsequent treatment of the sludge, increasing the frequency of sludge cleaning, and affecting the efficiency and cost of sewage treatment.

The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0020] Depend on Figure 1-3 It can be seen that a mud retaining device for a horizontal flow sedimentation tank comprises a concrete sedimentation tank structure 1, a horizontal flow sedimentation tank 2 is provided on one side of the interior of the concrete sedimentation tank structure 1, an inclined tube sedimentation tank 3 is provided on the other side of the interior of the concrete sedimentation tank structure 1, a water outlet trough 4 is connected to the top of the side of the inclined tube sedimentation tank 3 away from the horizontal flow sedimentation tank 2, a drainage pipe 5 is connected to the bottom of the water outlet trough 4, support trusses 6 are equidistantly provided inside the inclined tube sedimentation tank 3, a first fixing frame 7 is provided on the side where the support trusses 6 are close to each other, inclined tube fillers 8 are equidistantly provided inside the inclined tube sedimentation tank 3, the inclined tube fillers 8 are fixedly connected to the first fixing frame 7, mud collecting buckets 9 are equidistantly provided at the bottom of the inclined tube sedimentation tank 3, a mud discharge pipe 10 is provided inside the mud collecting bucket 9, and a fixed mud guard 11 is provided on the side where the horizontal flow sedimentation tank 2 and the inclined tube sedimentation tank 3 are close to each other;

[0021] During the specific implementation process, it is worth noting that the concrete sedimentation tank structure 1 is the main structure of the concrete structure sewage treatment sedimentation tank. Through the cooperation between the concrete sedimentation tank structure 1, the horizontal flow sedimentation tank 2, the inclined tube sedimentation tank 3, the outlet trough 4 and the drain pipe 5, the interior of the sewage treatment sedimentation tank is divided into two areas, namely the horizontal flow sedimentation tank 2 and the inclined tube sedimentation tank 3. A mixing reaction tank is provided on the side of the horizontal flow sedimentation tank 2 away from the inclined tube sedimentation tank 3 for coagulation reaction between sewage and coagulant, and preliminary precipitation is carried out in the horizontal flow sedimentation tank 2 to facilitate the subsequent separation of flocs and water bodies. The inclined tube sedimentation tank 3 is used to further accelerate the sedimentation process of suspended matter and fine particles in the sewage. The water after the sedimentation treatment is discharged by The inclined tube sedimentation tank 3 enters the outlet trough 4 and is discharged or transported to the next treatment process through the drainage pipe 5 at the bottom of the outlet trough 4. Through the cooperation between the inclined tube sedimentation tank 3, the supporting truss 6, the first fixed frame 7 and the inclined tube filler 8, by arranging the inclined tube filler 8 inside the inclined tube sedimentation tank 3, the unique inclined tube structure greatly increases the sedimentation area. At the same time, the shallow sedimentation principle is utilized to make the water flow slowly slide down along a specific angle in the inclined tube filler 8. The suspended matter and particulate matter are quickly settled to the bottom of the inclined tube sedimentation tank 3 under the action of gravity, thereby effectively improving the sedimentation efficiency of flocs and particulate matter. Through the cooperation between the inclined tube sedimentation tank 3, the mud collecting hopper 9 and the mud discharge pipe 10, the suspended matter and particulate matter settled to the bottom of the inclined tube sedimentation tank 3 are The sludge is collected in the sludge collecting hopper 9 and slowly deposited at the bottom of the hopper by gravity, forming a denser sludge layer. As the sludge layer gradually thickens, the control system of the sewage treatment facility automatically starts the sludge discharge operation, opens the valve of the sludge discharge pipe 10, and uses the action of water pressure or pump to safely and orderly discharge the sludge accumulated in the sludge collecting hopper 9 to the inclined tube sedimentation tank 3, avoiding interference with the water quality treatment process and secondary pollution. Through the coordination between the concrete sedimentation tank structure 1, the horizontal flow sedimentation tank 2, the inclined tube sedimentation tank 3 and the fixed mud guard 11, a fixed mud guard 11 is set at the connection between the flocculation sedimentation tank 2 and the inclined tube sedimentation tank 3 to avoid the bottom mud from being deposited in large quantities at the front end of the inclined tube sedimentation tank 3, and the height of the fixed mud guard 11 when it is set is the same as that of the inclined tube sedimentation tank 3. The height of the top of the pipe 9 is kept consistent, so that the direction of water flow can be smoothly transitioned to avoid resuspension. Through the coordination among the concrete sedimentation tank structure 1, the horizontal flow sedimentation tank 2, the inclined tube sedimentation tank 3, the outlet trough 4, the drainage pipe 5, the supporting truss 6, the first fixed frame 7, the inclined tube filler 8, the mud collecting hopper 9, the mud discharge pipe 10 and the fixed mud guard 11, by providing the fixed mud guard 11 at the connection between the horizontal flow sedimentation tank 2 and the inclined tube sedimentation tank 3, a large amount of sediment deposition at the front end of the inclined tube sedimentation tank 3 is avoided, thereby avoiding a large sediment treatment load at the front end of the inclined tube sedimentation tank 3, reducing the difference in sediment thickness at various positions at the bottom of the inclined tube sedimentation tank 3, reducing the frequency of sediment cleaning, and reducing the impact on sewage treatment efficiency and operating costs;

A connecting seat 16 is equidistantly fixedly connected to the side of the lifting adjustment plate 13 near the screw 17. The connecting seat 16 is threadedly connected to the screw 17.

[0023] In the specific implementation process, it is worth noting that, through the cooperation between the lifting groove 12, the lifting adjustment plate 13, the crossbeam 14, the servo motor 15, the connecting seat 16 and the screw 17, the servo motor 15 drives the screw 17 to rotate, so that the connecting seat 16 drives the lifting adjustment plate 13 to move up and down in the lifting groove 12, and when the screw 17 stops rotating, the lifting adjustment plate 13 remains stable. By adjusting the height of the lifting adjustment plate 13, the height of the fixed mud guard 11 can be extended, and the interception area of the suspended matter in the mud-water mixture can be increased, which is convenient for fine-tuning the sewage treatment sedimentation tank according to actual conditions, thereby improving the operating efficiency of the entire sewage treatment system.

The specific model of the radar level gauge 22 is not limited, and it only needs to meet the use requirements.
