[0010] Preferably, during use, the flocculant is put into the mixing tank through the feeding cylinder and the medicine outlet hole. Then, the external wastewater pipe is connected to the flange, so that the external wastewater enters the mixing tank through the wastewater inlet pipe and the connecting pipe. The wastewater will fall into the second fixed pipe and be blocked by the valve plate of the butterfly valve. The wastewater will stay above the valve plate of the butterfly valve. When the upper surface of the wastewater entering the mixing tank approaches the lowermost end of the water inlet hole, stop injecting wastewater into the mixing tank. Then, start the first motor to rotate the screw rod. The threaded sleeve will move up and down on the outer wall of the screw rod, causing the plugging column to move downward. Finally, use the side wall of the plugging column to block the water inlet hole, which can prevent the wastewater in the wastewater inlet pipe from continuing to flow into the mixing tank.

At the same time, since the rotation of the screw rod will drive the connecting rod to rotate, the connecting rod will drive the fixed ring to rotate, and the fixed ring will drive the stirring plate to rotate. The stirring plate will disturb and stir the wastewater located in the second fixed pipe, which will improve the mixing effect of the wastewater and the flocculant. In addition, when the screw rod rotates, the first gear ring will rotate, the first gear ring will drive the second gear ring to rotate, and the second gear ring will drive the dredging rod to rotate. The dredging rod will rotate in the center of the medicine outlet hole. The flocculant powder passing through the medicine outlet hole is not easy to be blocked, only making the inside of the medicine outlet hole damp and caked. Due to the rotation of the dredging rod, it is also convenient to dredge the residues on the inner wall of the medicine outlet hole through the rotation of the dredging rod. When the reaction is completed, open the butterfly valve to move the valve plate of the butterfly valve. The wastewater and the precipitate will enter the sewage pipe through the butterfly valve and the first fixed pipe. Then, start the second motor to rotate the auger, and the auger will spiral out the dirt, effectively avoiding the blockage of the precipitate in the pipe and solving the problem that the wastewater discharge pipe and the medicine adding pipe are prone to blockage during sewage discharge of the wastewater treatment pipeline sewage discharge device in the prior art, and the dirt cannot be quickly treated.
[0011] Preferably, the first gear ring is located above the bearing, and the central axis of the dredging rod and the central axis of the medicine outlet hole are collinear. The setting that the dredging rod is located at the central position of the medicine outlet hole can prevent the inside of the medicine outlet hole from being blocked.
[0012] Preferably, the upper end of the bearing ring is located below the water inlet hole. The bearing ring can support the lower end surface of the plugging column after it moves downward, thus facilitating the quick and stable bearing placement of the plugging column.
[0013] Preferably, both the first gear ring and the second gear ring are made of anti-corrosion materials. The setting that both the first gear ring and the second gear ring are made of anti-corrosion materials can improve the corrosion resistance of the first gear ring and the second gear ring in the wastewater environment and extend the service life of the first gear ring and the second gear ring.
[0014] Preferably, two ear plates are fixedly connected to the inner wall of the mixing tank. Limit rings are movably arranged at both the upper and lower ends of the ear plates. The inner wall of the limit ring is fixedly connected to the outer wall of the dredging rod. The outer wall of the dredging rod fits with the inner wall of the ear plate. When the dredging rod rotates, it will drive the limit ring to rotate, and the outer wall of the dredging rod will rotate along the inner wall of the ear plate, which is beneficial to the stable rotation of the dredging rod.
[0015] Preferably, the stirring plate is located in the upper half of the inner space of the second fixed pipe. The setting that the stirring plate is located in the upper half of the inner space of the second fixed pipe will not cause movement interference when the valve plate of the butterfly valve rotates, and at the same time, it is convenient to disturb and stir the flocculent precipitate accumulated in the second fixed pipe, which can improve the mixing effect of the drug and the wastewater.
[0016] Preferably, the inside of the first fixed pipe and the inside of the sewage discharge pipe are interconnected. The outer wall of the auger fits with the inner wall of the sewage discharge pipe. The wastewater and sediment passing through the first fixed pipe will fall into the gaps of the auger, and then through the way of spiral delivery, it can conveniently move the dirt out of the inner wall of the sewage discharge pipe quickly, which is convenient to use.
[0017] The beneficial effects of the present utility model:
[0018] 1. Pour the flocculant into the interior of the mixing tank through the feeding cylinder and the medicine outlet hole. Then connect the external wastewater pipe to the flange so that the external wastewater enters the interior of the mixing tank through the wastewater inlet pipe and the connecting pipe. The wastewater will fall into the second fixed pipe and be blocked by the valve plate of the butterfly valve. The wastewater will stay above the valve plate of the butterfly valve. When the upper surface of the wastewater entering the mixing tank approaches the lowermost end of the water inlet hole, stop injecting wastewater into the mixing tank continuously. Then start the first motor to make the screw rotate, and the threaded sleeve will move up and down on the outer wall of the screw, causing the plugging column to move downward. Finally, use the side wall of the plugging column to block at the water inlet hole, which can prevent the wastewater in the wastewater inlet pipe from continuing to flow into the interior of the mixing tank. The wastewater falling into the mixing tank will mix and react with the flocculant to produce flocculent precipitation, realizing the dosing treatment of wastewater. At the same time, since the rotation of the screw will drive the connecting rod to rotate, the connecting rod will drive the fixed ring to rotate, and the fixed ring drives the stirring plate to rotate. The stirring plate will disturb and stir the wastewater located in the second fixed pipe, which will improve the mixing effect of the wastewater and the flocculant. In addition, when the screw rotates, the first gear ring will rotate, the first gear ring drives the second gear ring to rotate, and the second gear ring drives the dredging rod to rotate. The dredging rod will rotate in the center of the interior of the medicine outlet hole. The flocculant powder passing through the medicine outlet hole is not easy to be blocked, only making the inside of the medicine outlet hole damp and caking. Due to the rotation of the dredging rod, it can also facilitate the dredging of the residues on the inner wall of the medicine outlet hole through the rotation of the dredging rod. When the reaction is completed, open the butterfly valve to make the valve plate of the butterfly valve move, and the wastewater and the precipitate will enter the sewage pipe through the butterfly valve and the first fixed pipe. Then start the second motor to make the auger rotate, and the auger will spiral out the dirt, effectively avoiding the blockage of the precipitate in the pipe and solving the problem that the wastewater discharge pipe and the dosing pipe in the existing wastewater treatment pipeline sewage discharge device are prone to blockage during sewage discharge and cannot quickly handle the dirt;
[0019] 2. Through the setting that the dredging rod is located at the central position of the medicine outlet hole, the blockage inside the medicine outlet hole can be avoided. The bearing ring can support the lower end surface of the plugging column after it moves downward, thus facilitating the quick and stable bearing placement of the plugging column. Through the setting that both the first gear ring and the second gear ring are made of anti-corrosion materials, the corrosion resistance of the first gear ring and the second gear ring in the wastewater environment can be improved, and the service life of the first gear ring and the second gear ring is increased;
[0020] 3. When the dredging rod rotates, it will drive the limit ring to rotate. The outer wall of the dredging rod will rotate along the inner wall of the ear plate, which is conducive to the stable rotation of the dredging rod. By arranging the stirring plate in the upper half of the internal space of the second fixed pipe, it will not cause movement interference to the rotation of the valve plate of the butterfly valve. At the same time, it is convenient to disturb and stir the flocculent precipitate accumulated in the second fixed pipe, which can improve the mixing effect of the drug and the wastewater. The wastewater and sediment passing through the first fixed pipe will fall into the gaps of the auger, and then through the way of spiral feeding, it can conveniently move the dirt out quickly from the inner wall of the sewage pipe, which is convenient to use.

[0042] Working principle: When working, a flocculant is put into the mixing tank 102 through the feeding cylinder 316 and the medicine outlet hole 315. Then, an external wastewater pipe is connected to the flange 203, so that the external wastewater enters the mixing tank 102 through the wastewater inlet pipe 201 and the connecting pipe 202. The wastewater will fall into the second fixed pipe 403 and be blocked by the valve plate of the butterfly valve 402;
[0043] At this time, the wastewater will stay at the upper end of the valve plate of the butterfly valve 402. When the upper end surface of the wastewater introduced into the mixing tank 102 approaches the lowermost end of the water inlet hole 104, the injection of wastewater into the mixing tank 102 is stopped. Then, the first motor 302 is started to make the screw 303 rotate, and the threaded sleeve 304 will move up and down on the outer wall of the screw 303, so that the plugging column 305 moves downward.

[0044] The wastewater falling into the mixing tank 102 will be mixed and reacted with the flocculant to produce flocculent precipitation, realizing the dosing treatment of the wastewater. At the same time, since the rotation of the screw 303 will drive the connecting rod 306 to rotate, the connecting rod 306 will drive the fixed ring 307 to rotate, and the fixed ring 307 drives the stirring plate 308 to rotate.

[0045] In addition, when the screw 303 rotates, the first tooth ring 311 will rotate. The first tooth ring 311 drives the second tooth ring 313 to rotate, and the second tooth ring 313 drives the dredging rod 312 to rotate. The dredging rod 312 will rotate at the inner center of the medicine outlet hole 315. The flocculant powder passing through the medicine outlet hole 315 is not easily blocked, and only makes the inside of the medicine outlet hole 315 damp and caked. Due to the rotation of the dredging rod 312, it is also convenient to dredge the residues on the inner wall of the medicine outlet hole 315 through the rotation of the dredging rod 312;
[0046] After the reaction is completed, open the butterfly valve 402 to move the valve plate of the butterfly valve 402, and the wastewater and sediment will enter the sewage discharge pipe 501 through the butterfly valve 402 and the first fixed pipe 401. Then, turn on the second motor 503 to rotate the auger 504, and the dirt can be spirally sent out through the auger 504.
