[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention inputs polyacrylamide solution into the flow channel in the active rod and then discharges it through the output port. At this time, the polyacrylamide solution is mixed with the sewage in the S-shaped pipe, and the sewage in the S-shaped pipe is stirred by the rotation of multiple stirring blades, so that the sewage and the polyacrylamide solution can be fully mixed together. The S-shaped pipe has a long flow stroke, so that the flowing sewage can stay in the S-shaped pipe for a long time, and has time for the sludge impurities in the sewage to be mixed and flocculated, so that the flowing sewage can complete the flocculation of the sludge impurities when it is discharged through the S-shaped pipe.

[0016] 2. The present invention injects high-pressure gas into the three-way connector through the operation of an air pump, and then the gas and polyacrylamide solution are discharged through the flow channel and the output port together, so that the injection intensity of the polyacrylamide solution discharged from the output port is improved, and a strong impact airflow can be generated at a local position of the output port, so that sludge impurities are kept away from the output port, and the probability of impurities in the sewage blocking the output port can be reduced. At the same time, through the one-way valve flap set in the output port, when gas and liquid are not output from the output port, the one-way valve flap made of rubber material will be closed to block the output port and prevent sewage from entering the output port.

[0017] 3. The present invention allows sewage to enter the centrifugal cylinder after being discharged from the S-shaped pipe. The centrifugal cylinder rotates to discharge the sewage from multiple through holes opened on the circumferential surface of the centrifugal cylinder, and the flocculated sludge impurities will adhere to the inner surface of the centrifugal cylinder. At this time, the sludge impurities remaining in the centrifugal cylinder can be discharged under the action of the spiral blades rotating in the centrifugal cylinder. Finally, the sludge impurities are further squeezed by the squeezing mechanism, so that the water content of the sludge can be lower, and the volume of the sludge will also become smaller, which is convenient for subsequent collection.

[0030] The sludge treatment mechanism 3 includes a rotating seat 301, a guide seat 303, a centrifugal barrel 304 and a spiral blade 502. The rotating seat 301 is arranged on the machine base 1. A plurality of rotating wheels 302 are arranged in the rotating seat 301. A pair of guide seats 303 are rotatably arranged between the plurality of rotating wheels 302. The centrifugal barrel 304 is arranged in a pair of guide seats 303. A plurality of through holes 305 are opened on the circumferential surface of the centrifugal barrel 304. The spiral blade 502 is rotatably connected in the centrifugal barrel 304.

[0031] In actual application, by connecting the sewage discharge pipe to the input end of the S-shaped pipe 213, the sewage can be transported to the S-shaped pipe 213. When the sewage flows in the S-shaped pipe 213, the polyacrylamide solution is input into the three-way connector 216, and then enters the flow channel 217 in the active rod 214, so that it is discharged through the output port 218. At this time, the polyacrylamide solution is mixed with the sewage in the S-shaped pipe 213. At the same time, the first motor 2111 drives the driven rod 215 to rotate, and then the first sprocket group 2110 is used to make the driven rod 215 rotate. The plurality of driven rods 215 and the active rod 214 rotate simultaneously, thereby driving the plurality of stirring blades 219 to rotate, stirring the sewage in the S-shaped pipe 213, so that the sewage and the polyacrylamide solution can be fully mixed together, and the S-shaped pipe 213 has a long flow stroke, so that the flowing sewage can stay in the S-shaped pipe 213 for a long time, and has time for the sludge impurities in the sewage to be mixed and flocculated, so that the flowing sewage can complete the flocculation of the sludge impurities when it is discharged through the S-shaped pipe 213, and at the same time, when the polyacrylamide solution is input into the three-way connector 216 By controlling the operation of the air pump 221, the air pump 221 injects high-pressure gas into the three-way connector 216, so that the gas and the polyacrylamide solution are discharged through the flow channel 217 and the output port 218, thereby increasing the jet intensity of the polyacrylamide solution discharged from the output port 218, and generating a strong impact airflow at a local position of the output port 218 to impact the surrounding sludge impurities, so that the sludge impurities are kept away from the output port 218, and the probability of the impurities in the sewage blocking the output port 218 can be reduced. At the same time, through the one-way valve flap 222 set in the output port 218, the output port 218 When no gas or liquid is outputted from the centrifugal cylinder 304, the one-way valve flap 222 made of rubber will be closed to block the output port 218 to prevent sewage from entering the output port 218. Finally, when the sewage is discharged from the S-shaped pipe 213, it will enter the centrifugal cylinder 304. Through the rotation of the centrifugal cylinder 304, the sewage can be discharged from the multiple through holes 305 opened on the circumferential surface of the centrifugal cylinder 304, and the flocculated sludge impurities will adhere to the inner surface of the centrifugal cylinder 304. At this time, the sludge impurities remaining in the centrifugal cylinder 304 can be discharged under the action of the spiral blades 502 rotating in the centrifugal cylinder 304.

[0032] In one case of an embodiment of the present invention, the one-way valve flap 222 is made of rubber material, one of the open ends of which is composed of a pair of valve flaps that can be opened and closed. When liquid or gas is output in the flow channel 217, a group of valve flaps at the open end of the one-way valve flap 222 will open to allow liquid and gas to be output. When liquid or gas is not output in the flow channel 217, a group of valve flaps at the open end of the one-way valve flap 222 will be in a closed state to prevent sewage from entering the flow channel 217, thereby achieving a one-way output effect.

[0033] like Figure 2 and 3 As shown, as a preferred embodiment of the present invention, a liquid storage tank 4 and a liquid pump 401 are provided at the upper end of the mounting shell 211, the liquid storage tank 4 is used to store polyacrylamide solution, and both ends of the liquid pump 401 are connected to the liquid storage tank 4 and the three-way connector 216 through connecting pipes respectively.

[0034] In actual application, by controlling the operation of the liquid pump 401, the liquid pump 401 will transport the polyacrylamide solution in the liquid storage tank 4 to the three-way connector 216 through the connecting pipe, thereby achieving the effect of inputting the polyacrylamide solution into the flow channel 217 of the active rod 214.

[0035] like Figure 2 and 6 As shown, as another preferred embodiment of the present invention, the output end of the S-shaped pipe 213 is fixedly connected with a connecting flange 2112, and the connecting flange 2112 is rotatably connected to the centrifugal cylinder 304.

[0036] In actual application, the embodiment of the present invention achieves a bridging effect between the S-shaped pipe 213 and the centrifugal cylinder 304 through the action of the connecting flange 2112, thereby realizing the transfer and transportation of sewage.

[0037] like Figure 5 and 6 As shown, as another preferred embodiment of the present invention, a discharge box 5 is arranged at the upper end of the machine base 1, and a rotating rod 501 is rotatably connected in the discharge box 5, and the rotating rod 501 is fixedly connected to the spiral blade 502, and the upper end of the discharge box 5 is rotatably connected to the driving shaft 503 and the driven shaft 504 through the rotating seat, and the rotating rod 501 and the driving shaft 503 are connected through the second sprocket set 505, and the circumferential surfaces of the driving shaft 503 and the driven shaft 504 are fixedly connected with mutually meshing first gears 506, and the first gear 506 fixed on the circumferential surface of the driven shaft 504 is also meshed with a ring gear 507, and the ring gear 507 is arranged on the circumferential surface of the centrifugal barrel 304, and the rotating rod 501 is connected to the output end of the second motor 508 arranged at the front end of the discharge box 5.

[0038] When the embodiment of the present invention is actually applied, after the sewage enters the centrifugal barrel 304, the second motor 508 is controlled to operate, and the second motor 508 will drive the rotating rod 501 to rotate, and the rotating rod 501 will drive the spiral blade 502 to rotate. The rotating rod 501 will drive the driving shaft 503 to rotate under the action of the second sprocket set 505, and the driving shaft 503 will drive the driven shaft 504 to rotate under the action of the first gear 506, and the driven shaft 504 will drive the centrifugal barrel 304 to rotate under the action of the first gear 506 and the ring gear 507. Due to the change in the transmission ratio between the first gear 506 and the ring gear 507, the speed of the spiral blade 502 is slightly greater than the speed of the centrifugal barrel 304. At this time, the spiral blade 502 can push the sludge attached to the inner wall of the centrifugal barrel 304 to the outside of the centrifugal barrel 304, and the sludge will be output through the front end of the centrifugal barrel 304 and finally enter the discharge box 5.

[0040] In actual application of the embodiment of the present invention, when the centrifugal cylinder 304 rotates, a large amount of liquid will be thrown out through the through hole 305, and then collected by the collecting cylinder 509, and finally the liquid is discharged through the discharge port 5010 and the L-shaped discharge pipe 5011.

[0041] like Figure 8 and 9 As shown, as another preferred embodiment of the present invention, a pair of discharge shells 5012 are arranged on the circumferential surface of the discharge box 5, and the lower end of the discharge shell 5012 is connected to an extrusion mechanism 6, which is used to achieve dry-wet separation.

[0042] In actual application of the embodiment of the present invention, after the sludge enters the discharge box 5, the sludge will continue to be transported downward through the discharge shells 5012 on the left and right sides, and finally transported to the extrusion mechanism 6 through the discharge shells 5012 to complete the final solid-liquid separation.

[0043] like Figure 8 and 9As shown, as another preferred embodiment of the present invention, the extrusion mechanism 6 includes a pair of extrusion boxes 601, and the pair of extrusion boxes 601 are arranged on the machine base 1, and a pair of rotating shafts 602 and a connecting shaft 603 are rotatably connected in the extrusion box 601, and the circumferential surfaces of the rotating shafts 602 are fixedly connected with conveying rollers 604, and a conveyor belt 605 with an inclined angle is connected between the conveying rollers 604, and the circumferential surfaces of the connecting shafts 603 are fixedly connected with extrusion rollers 606, and the circumferential surfaces of the rotating shafts 602 and the connecting shafts 603 are fixedly connected with mutually meshing second gears 607, and the rotating shaft 602 is connected to the output end of the third motor 608 arranged at the left end of the extrusion box 601.

[0044] In actual application of the embodiment of the present invention, after the sludge enters the squeezing box 601, it will first fall on the conveyor belt 605. At this time, the third motor 608 is operated to drive the conveyor belt 605 to rotate, and the conveyor belt 605 will transport the sludge backward until it is transported to the squeezing roller 606. Since the squeezing roller 606, the conveying roller 604 and the conveyor belt 605 rotate in opposite directions, when the sludge passes through the squeezing roller 606, the conveying roller 604 and the conveyor belt 605 cooperate to squeeze the passing sludge, so that the sewage remaining in the sludge can be squeezed out of the sludge, so that the water content of the sludge output from the squeezing box 601 is lower, and the volume of the sludge will also become smaller, which is convenient for subsequent collection.

[0045] like Fig. 9 As shown, as another preferred embodiment of the present invention, a discharge hole 609 is provided at the front end of the extrusion box 601 , and a three-way discharge pipe 6010 is provided in the discharge hole 609 .

[0046] In actual application of the embodiment of the present invention, when the sludge is squeezed, the sewage separated from the sludge will flow forward on the inclined conveyor belt 605, then fall to the bottom of the squeezing box 601, and finally be discharged and collected through the three-way discharge pipe 6010 set in the discharge cylinder.
