Application No. 202222987961.9 discloses a settling tank for wastewater treatment. This device can easily filter overflow water by setting an overflow pipe, a pipe cover, and a filter screen. With the above structure, the settling tank has the advantage of having an inner wall cleaning function during use. However, during the use of this device, there will be a certain height difference between the separation layer between particles and fluids, which will prevent the clear liquid from being fully discharged during the discharge of the clear liquid through the overflow pipe, greatly reducing the practicality of the device.

[0003] Therefore, it is necessary to provide a continuously separating settling tank for wastewater treatment to solve the above-mentioned technical problems. Utility Model Content

[0023] After completion, the cleaning solution is poured into the inside of the mixing drum 22 through the connecting pipe 27. The drive motor 25 starts working, driving the stirring rod 23. The stirring rod 23 drives the stirring component 24 to stir the cleaning solution, making it evenly mixed. The first regulating valve is manually turned so that the mixed cleaning solution is transported to the inside of the tank 10 through the conveying pipe 26.

[0024] The discharge assembly 30 includes a fixed frame 31 disposed on the front side of the tank 10, a lifting frame 32 disposed on the top of the fixed frame 31, a sewage pump 33 disposed at the center of the inner side of the lifting frame 32, and discharge pipes 34 connected to both the front and rear sides of the sewage pump 33.

A groove is opened near the center of the top of the fixed frame 31, and a hydraulic rod 35 for adjusting the height of the lifting frame 32 is fixedly installed at the bottom of the inner side of the groove.

[0025] During operation, wastewater enters the tank 10 through the inlet pipe for separation of particles and fluid. After separation, the height of the separation is determined by the observation window 60. The hydraulic rod 35 then starts working, driving the lifting frame 32 to move up and down. The lifting frame 32 drives the sliding rod 36 to slide inside the fixed frame 31, increasing the stability of the lifting frame 32. This allows the discharge pipe 34 inside the tank 10 to be adjusted to a suitable height. The wastewater pump 33 then starts working, drawing out the clarified liquid through the rear discharge pipe 34 and discharging it through the front discharge pipe 34. The liquid is then filtered through the filter sleeve.

[0026] A conveying pipe 26 is provided on the left side of the mixing drum 22 and connected to the top of the tank 10. A first regulating valve is provided on the front side of the conveying pipe 26 near the center. A connecting pipe 27 is fixedly installed on the top of the mixing drum 22.

The bottom bevel gear 45 is fixedly connected to the top of the driven rod 41.

[0030] During operation, the drive motor 25 drives the driven rod 41 to rotate through the meshing of two bevel gears 45. The driven rod 41 drives the first cleaning plate 43 and the second cleaning plate 44 to rotate, scraping and cleaning the dirt that has settled and adhered to the inner wall of the isolation funnel 42 and the tank 10, preventing the dirt from forming scale. The sewage is then discharged through the drain pipe 50. This device is simple to operate and easy to use, thus meeting the needs of customers.

[0031] A drain pipe 50 is connected to the bottom of the left side of the tank 10. A second regulating valve is installed in front of the drain pipe 50. An observation window 60 is installed near the center of the left side of the tank 10. An inlet pipe is fixedly installed on the top of the tank 10.

[0032] The working principle of the continuous separation sedimentation tank for wastewater treatment provided by this utility model is as follows:

[0033] Step 1: During the operation of the device, wastewater enters the tank 10 through the inlet pipe for separation between particles and fluid. After separation, the height of the separation is determined by the observation window 60. The hydraulic rod 35 starts working, driving the lifting frame 32 to move up and down. The lifting frame 32 drives the sliding rod 36 to slide inside the fixed frame 31, increasing the stability of the lifting frame 32. This adjusts the discharge pipe 34 inside the tank 10 to a suitable height. The wastewater pump 33 starts working, drawing out the clarified liquid through the rear discharge pipe 34 and discharging it through the front discharge pipe 34. The liquid is then filtered through the filter sleeve.

[0034] Step 2: After completion, pour the cleaning solution into the inside of the mixing drum 22 through the connecting pipe 27. The drive motor 25 starts working, driving the stirring rod 23. The stirring rod 23 drives the stirring component 24 to stir the cleaning solution and make it evenly mixed. Manually turn the first regulating valve to transport the mixed cleaning solution to the inside of the tank 10 through the conveying pipe 26.

[0035] Step 3: During operation, the drive motor 25 drives the driven rod 41 to rotate through the meshing of two bevel gears 45. The driven rod 41 drives the first cleaning plate 43 and the second cleaning plate 44 to rotate, scraping and cleaning the dirt that has settled and adhered to the inner wall of the isolation funnel 42 and the tank 10, preventing the dirt from forming scale. The sewage is then discharged through the drain pipe 50. This device is simple to operate and easy to use, thus meeting the needs of customers.

[0037] By coordinating the various components of the device, wastewater enters the tank 10 through the inlet pipe for separation of particles and fluid. After separation, the height of the separation is determined by the observation window 60. The hydraulic rod 35 then starts working, driving the lifting frame 32 to move up and down. The lifting frame 32 drives the sliding rod 36 to slide inside the fixed frame 31, increasing the stability of the lifting frame 32. This adjusts the discharge pipe 34 inside the tank 10 to a suitable height, and the wastewater pump 33 starts working, drawing out the clarified liquid through the rear discharge pipe 34 and discharging it through the front discharge pipe 34. The liquid is then filtered through the filter sleeve.
