Through the purified water outlet 12 and the sludge outlet 13, the water and sludge are discharged separately.

[0029] A plurality of delivery holes 202 are provided on the outer wall of the stirring shaft 2 . The delivery holes 202 are communicated with the solution tank 201 . The delivery holes 202 are located at a high position, thereby preventing the delivery holes 202 from being blocked by sewage.

[0030] In this embodiment, first, the stirring container 1 and the upper cover 4 are fixedly installed through the flange 101, the bearing 43 is placed in the annular groove 42, and the stirring shaft 2 is passed through the through hole 41 and fixedly installed through the bearing 43. Then, the chemical agent delivery pipe 3 is placed in the solution tank 201 of the stirring shaft 2, and then the sewage is flowed into the stirring container 1 from the wastewater delivery inlet 11; When sewage needs to be purified, the chemical solution flows into the solution tank 201 through the chemical delivery pipe 3. The chemical solution in the solution tank 201 is filled and sprayed into the sewage liquid through the delivery hole 202. After that, the tool 21 of the stirring shaft 2 rotates and stirs. After the stirring work is completed, the sewage is left to stand for a period of time and is layered into sludge and water. The sludge and water flow out through the sludge outlet 13 and the purified water outlet 12 respectively.

[0031] The top of the stirring shaft 2 is fixedly connected to the fixed block 22, the top of the fixed block 22 is fixedly connected to the electric retractor 5, the electric retractor 5 is slidably connected to one end of the pushing rod 51, the other end of the pushing rod 51 is fixedly connected to one end of the connecting block 52, the other end of the connecting block 52 is fixedly connected to the gate block 53, the inner and outer walls of the gate block 53 are slidably connected to the inner wall of the solution tank 201 and the outer wall of the chemical agent delivery pipe 3 respectively, to realize the opening and closing of the delivery hole 202, so as to prevent the sewage from flowing back into the solution tank 201 when the sewage is being stirred.

[0032] In this embodiment, when the sewage needs to be purified, the electric telescopic device 5 starts working, drives the push rod 51 to move, and drives the gate block 53 to move upward through the connecting block 52, so that the bottom of the gate block 53 is away from the delivery hole 202. At the same time, the solution tank 201 forms a flow space and flow pressure for the chemical solution, and the chemical solution passes through the delivery hole 202 and flows into the stirring container 1 in a jet shape; when the sewage needs to be purified and stirred, the electric telescopic device 5 starts working again, drives the push rod 51 to move, and drives the gate block 53 to move downward through the connecting block 52, so that the bottom of the gate block 53 is placed below the delivery hole 202, thereby closing the delivery hole 202.

[0033] The bottom of the upper cover 4 is fixedly connected to the sealing buffer assembly 6, which includes a lower cover 61, a sealing block 62 and a spring 63. The lower cover is provided with a plurality of slide grooves 611, which are slidably connected to the sealing block 62, and one end of the sealing block 62 is fixedly connected to the spring 63.

[0035] In this embodiment, the sealing block 62 is placed in the slide groove 611 of the lower cover 61, and then the lower cover 61 is fixedly installed with the upper cover 4. When the sewage needs to be purified and stirred, the groove 203 of the stirring shaft 2 rotates on the block 621 of the sealing block 62. Due to stirring for a period of time, the chemical solution and the sewage react to form a dirt mass, which further affects the stability of the stirring. If the dirt mass hits the cutter 21, the stirring shaft 2 is quickly kept stable by the spring 63.

[0036] The outer wall of the stirring shaft 2 is also fixedly connected to the inner wall of the turbine 23 . The outer teeth of the turbine 23 mesh with one end of the worm 24 . The other end of the worm 24 is fixedly connected to the first motor 25 .

[0037] The sludge outlet 13 is fixedly connected to one end of the mud discharge valve 7, the mud discharge valve 7 includes a first shell 71, a second motor 72 and a ball valve 73, one end of the shell 71 is fixedly connected to the second motor 72, the second motor 72 is fixedly connected to one end of the main shaft 721, the other end of the main shaft 721 is fixedly connected to the ball valve 73, the other end of the mud discharge valve 7 is fixedly connected to the mud discharge screw conveying pump 8, the mud discharge screw conveying pump 8 includes a second shell 81, a third motor 82 and a screw 83, one end of the second shell 81 is fixedly connected to the third motor 82, the third motor 82 is fixedly connected to the screw 83.

[0038] In this embodiment, when the sewage needs to be purified and stirred, the first motor 25 starts working, drives the turbine 23 to rotate, drives the stirring shaft 2 to rotate, and then causes the cutter 21 to perform stirring work until the stirring work is completed, and the first motor 25 stops working. When the sewage purification and stirring are completed and the sludge is settled, the second motor 72 starts working, drives the main shaft 721 to drive the ball valve 73 to rotate, and then the sludge is discharged downward. At the same time, the third motor 82 starts working, drives the screw 83 to rotate, so that the sludge is discharged. When the sludge is completely discharged, the second motor 72 starts working again, resets the ball valve 73, closes the sludge outlet 13, and the third motor 82 also stops rotating.

[0039] The inner walls of the wastewater delivery inlet 11 and the purified water outlet 12 are respectively provided with a first delivery hose 111 and a second delivery hose 121 , and the first delivery hose 111 and the second delivery hose 121 are respectively fixedly connected to the honeycomb floating plate 9 .

[0040] In this embodiment, when sewage needs to be purified, the sewage is transported to the stirring container 1 through the first conveying hose 111, and the sewage causes the honeycomb float 9 to rise. After the sewage stirring work is completed, the sewage is left to stand for a period of time and is stratified into sludge and water. The water is filtered through the honeycomb float 9 and discharged through the second conveying hose 121, while causing the honeycomb float 9 to descend.

[0041] The flange 101 and the upper cover 4 are fixedly connected via a sealing gasket 44 to improve the sealing performance of the device.

[0042] Working principle: First, insert the first conveying hose 111 and the second conveying hose 121 through the wastewater conveying inlet 11 and the purified water outlet 12 respectively, and fix the honeycomb floating plate 9 to install the first conveying hose 111 and the second conveying hose 121 respectively. Then, place the bearing 43 in the annular groove 42 of the upper cover 4, and fix the stirring shaft 2 through the through hole 41 and the bearing 43. Then, place the sealing block 62 and the spring 63 in the slide groove 611 of the lower cover 61, and the block 621 of the sealing block 62 is engaged with the groove 203 of the stirring shaft 2. Then, fix the lower cover 61 and the upper cover 4 together. Subsequently, fix the stirring container 1 and the upper cover 4 through the flange 101, wherein the sealing gasket 44 is connected between the stirring container 1 and the upper cover 4. Finally, install the fixed block 22 and the electric telescopic device 5 on the top of the stirring shaft 2, and fix the gate block 53 by the push rod 51. Place the outer wall of the chemical delivery pipeline 3 in the solution tank 201 in contact with the inner wall of the gate block 53.

[0043] When sewage needs to be purified, the sewage is transported to the stirring container 1 through the first delivery hose 111. The sewage causes the honeycomb floating plate 9 to rise, and the electric expansion joint 5 starts to work, driving the push rod 51 to move, and driving the gate block 53 to move upward through the connecting block 52, so that the bottom of the gate block 53 is away from the delivery hole 202, and the chemical solution flows into the solution tank 201 through the chemical delivery pipe 3. The chemical solution in the solution tank 201 is filled and sprayed into the sewage liquid through the delivery hole 202; When the sewage needs to be purified and stirred, the electric telescopic device 5 starts working again, drives the push rod 51 to move, drives the gate block 53 to move downward through the connecting block 52, so that the bottom of the gate block 53 is placed below the conveying hole 202, and then closes the conveying hole 202. The first motor 25 starts working, drives the turbine 23 to rotate, drives the stirring shaft 2 to rotate, and then makes the cutter 21 perform stirring work. During the stirring process, the chemical solution and the sewage react to form a dirt mass, which affects the stability of the stirring. If the dirt mass hits the cutter 21, the stirring shaft 2 is quickly kept stable by the spring 63; After the stirring work is completed, the sewage is left to stand for a period of time and is layered into sludge and water. The water is filtered through the honeycomb float 9 and discharged through the second conveying hose 121, while the honeycomb float 9 is lowered. Then, the first motor 25 starts to work, drives the turbine 23 to rotate, drives the stirring shaft 2 to rotate, and then makes the tool 21 perform stirring work until the stirring work is completed. The first motor 25 stops working. When the sewage purification and stirring are completed, the sludge is settled. The second motor 72 starts to work, drives the main shaft 721 to drive the ball valve 73 to rotate, and then the sludge is discharged downward. At the same time, the third motor 82 starts to work, drives the screw 83 to rotate, so that the sludge is discharged. When the sludge is completely discharged, the second motor 72 starts to work again, resets the ball valve 73, closes the sludge outlet 13, and the third motor 82 also stops rotating.
