[0002] Sewage sludge is the accumulated solid sediment separated from various types of water, which is wet or mixed with liquid components. It is the product of natural or artificial treatment processes. The sewage generated by urban sewage, water supply plants and industrial wastewater treatment stations during the production process contains a lot of sludge. When treating sewage containing sludge, it is necessary to separate the sewage and sludge first; Generally, when separating mud and water from sludge, the separation effect is mostly achieved through gravity and sedimentation.

After that, the staff only needs to open the discharge door to handle the sludge.

[0012] The present invention has the following beneficial effects: 1. The present invention first connects the water inlet on the top of the top cover with the pipeline for conveying the sludge to be treated, and then starts the motor. When the motor is working, it will drive the transmission rod and the conical cylinder to rotate. When the conical cylinder rotates, it will generate an outward throwing force on the sludge entering the main body through centrifugal force, so that the sludge can be close to the inner wall of the conical cylinder. At the same time, under the action of centrifugal force, the water in the sludge can be quickly and effectively separated, and the water is thrown out through the filter holes. After that, the sludge with part of the water thrown out will fall between the upper top plate and the lower top plate. At the same time, when the conical cylinder rotates, the rotating conical cylinder will drive the gear shaft to rotate through the teeth on the outer surface. When the gear shaft rotates, it will rotate in the bidirectional thread groove inside the bidirectional thread sleeve through the plug rod on the outer surface, and drive the lower top plate inside through the bidirectional thread sleeve. The inside of the sleeve moves back and forth, and when the lower top plate moves upward, the moving lower top plate will drive the silt on the lower top plate to rise and fit to the bottom of the upper top plate. Then, when the lower top plate continues to rise, the lower top plate will drive the silt to squeeze the upper top plate. Since the upper top plate is fixed, when the lower top plate drives the silt to squeeze the upper top plate, the reaction force generated by the upper top plate will act on the silt, causing the silt to be squeezed on both sides. At this time, the silt will become a mud cake after being squeezed, and the residual water will be discharged outward through the filter holes on the inner sleeve. When the mud and water are separated by the centrifugal force generated by the extrusion of the lower top plate and the rotation of the conical cylinder, a double filtration system is formed, which increases the speed at which water passes through the filter net and the filter plate. Compared with the traditional gravity sedimentation separation method, the separation time is greatly shortened, thereby improving the separation efficiency of sewage sludge as a whole.

[0013] When the upper and lower rotating frames are rotated, the two rotating frames are respectively fitted on the side walls of the upper and lower plates and the lower and lower rotating frames are located in the gap in the middle of the lower top plate. When the upper and lower rotating frames are rotated, the two rotating frames are respectively fitted on the side walls of the upper and lower plates and the lower and lower rotating frames are located in the gap in the middle of the lower top plate. When the upper and lower rotating frames are rotated, the two rotating frames are respectively fitted on the side walls of the upper and lower plates and the lower and lower rotating frames are located in the gap in the middle of the lower top plate. When the upper and lower rotating frames are rotated, the two rotating frames are respectively fitted on the side walls of the upper and lower plates and the lower and lower rotating frames are located in the gap in the middle of the lower top plate. When the upper and lower rotating frames are rotated, the two rotating frames are respectively fitted on the side walls of the upper and lower plates and the lower and lower rotating frames are located in the gap in the middle of the lower When the cam is in the state of being moved upward by the action of the spring, the cam at the bottom of the gear train is moved upwardly and the cam is moved downwardly and the cam is moved back and forth, thereby the cam is moved upwardly and the cam is moved back and forth, thereby the cam is moved upwardly and the cam is moved back and forth, thereby the cam is moved

[0014] 3. In the present invention, when the transmission rod drives the conical cylinder to rotate, the rotation of the transmission rod will drive the arc sleeve to rotate. When the arc sleeve rotates, it will continuously squeeze the raised ring. After being squeezed, the raised ring will move downward on the surface of the vibration sleeve. When the raised ring moves downward, it will push the swing shaft to rotate through the middle rod. When the swing shaft rotates, it will fit the inner wall of the conical cylinder. Then, when the conical cylinder rotates, it will drive the rotating sleeve and the turntable 2 on the spiral shaft to rotate. When the turntable 2 rotates, it will drive the spiral cylinder to rotate. When the spiral cylinder rotates, it will pass the connecting ring to push the air at the opening of the transmission rod. The gas is drawn into the swing shaft. When the gas enters the swing shaft, the gas will be accelerated by the spiral structure on the spiral shaft. Then the fast-flowing gas will enter the one-way port through the circular hole inside the swing shaft and be ejected. At this time, the ejection of gas can generate a certain airflow pressure, which helps to push the water in the sludge to flow to the water outlet of the conical cylinder, thereby accelerating the separation speed of the water. At the same time, the rotation of the rotating sleeve can squeeze the sludge at different positions on the conical cylinder, so that the water in the sludge can be squeezed out more fully, further enhancing the separation effect of the device and improving the use efficiency.

[0015] 4. In the present invention, when the raised ring is squeezed by the arc sleeve and moves downward, the movement of the raised ring will drive the spring disk to move downward. When the spring disk moves downward, it will push the curved tube through the rotating tube, so that the curved tube rotates on the outer ring. When the curved tube rotates, it will fit against the inner wall of the conical tube. When the conical tube drives the sludge to rotate, the curved shape of the curved tube can effectively guide the sludge on the inner wall of the conical tube to flow downward along a specific path, reducing the accumulation and residence time of the sludge on the inner wall of the conical tube, thereby improving the overall sludge separation efficiency. In the process of the curved tube fitting against the inner wall, its own shape can play a certain scraping role, which can clean the sludge on the inner wall of the conical tube, so that less sludge remains on the inner wall, thereby maintaining the good filtering performance of the conical tube.

After being squeezed, the blocking door 105 will push the spring rod 104. At this time, the conical cylinder 203 will push the sludge into between the discharge door 103 and the blocking door 105. After that, the staff only needs to open the discharge door 103 to handle the sludge.

[0028] When in use, first connect the water inlet on the top of the top cover 101 to the pipeline for conveying the sludge to be treated, and then start the motor. When the motor is working, it will drive the transmission rod 202 and the conical cylinder 203 to rotate. When the conical cylinder 203 rotates, it will generate an outward throwing force on the sludge entering the main body 1 through centrifugal force, so that the sludge can cling to the inner wall of the conical cylinder 203. At the same time, under the action of centrifugal force, the water in the sludge can be quickly and effectively separated, and then the sludge will fall between the lower top plate 205 and the upper top plate 204. Afterwards, the rotation of the conical cylinder 203 will also drive the gear shaft 207 to rotate and make the lower top plate 205 move up. When the lower top plate 205 moves up, it will squeeze the sludge to further separate the sludge from the water. Then the outlet pipe 102 can be opened to discharge the water. At the same time, the transmission rod 202 will also drive the conical cylinder 203 to push the sludge on the lower top plate 205 onto the blocking door 105 and squeeze the blocking door 105. After being squeezed, the blocking door 105 will push the spring rod 104. At this time, the conical cylinder 203 will push the sludge into between the discharge door 103 and the blocking door 105. After that, the staff only needs to open the discharge door 103 to handle the sludge.

[0029] First, connect the water inlet on the top of the top cover 101 to the pipeline for conveying the sludge to be treated, and then start the motor. When the motor is working, it will drive the transmission rod 202 and the conical cylinder 203 to rotate. When the conical cylinder 203 rotates, it will generate an outward throwing force on the sludge entering the main body 1 through centrifugal force, so that the sludge can be close to the inner wall of the conical cylinder 203. At the same time, under the action of centrifugal force, the water in the sludge can be quickly and effectively separated, and the water is thrown out through the filter holes. After that, the sludge with some water thrown out will fall between the upper top plate 204 and the lower top plate 205. At the same time, when the conical cylinder 203 rotates, the rotating conical cylinder 203 will drive the gear shaft 207 to rotate through the teeth on the outer surface. When the gear shaft 207 rotates, it will rotate in the bidirectional thread groove inside the bidirectional threaded sleeve 206 through the plug rod on the outer surface, and drive the lower top plate 205 to rotate in the inner sleeve 201 through the bidirectional threaded sleeve 206. The inner part of the conical cylinder 203 reciprocates, and when the lower top plate 205 moves upward, the moving lower top plate 205 will drive the silt on the lower top plate 205 to rise and fit the bottom of the upper top plate 204. Then, when the lower top plate 205 continues to rise, the lower top plate 205 will drive the silt to squeeze the upper top plate 204. Since the upper top plate 204 is fixed, when the lower top plate 205 drives the silt to squeeze the upper top plate 204, the reaction force generated by the upper top plate 204 will act on the silt, so that the silt is squeezed on both sides. At this time, the silt will become a mud cake after being squeezed, and the residual water therein will be discharged outward through the filter holes on the inner sleeve 201. When the mud and water are separated by the centrifugal force generated by the squeezing of the lower top plate 205 and the rotation of the conical cylinder 203, a double filtering system is formed, which increases the speed at which water passes through the filter screen and the filter plate. Compared with the traditional gravity sedimentation separation method, the separation time is greatly shortened, thereby improving the separation efficiency of sewage sludge as a whole.

[0030] When the lower top plate 205 is pulled upward by the bidirectional threaded sleeve 206 inside the inner sleeve 201, the moving lower top plate 205 will squeeze the rotating frame 303 at the bottom. When the rotating frame 303 is squeezed, it will rotate on the surface of the transmission rod 202. When the rotating frame 303 rotates, it will push the C-shaped plate 301 to move upward inside the rectangular groove through the connecting rod 302. When the C-shaped plate 301 moves upward, it will pull the rotating frame 303 at the top through the connecting rod 302 at the top, so that the rotating frame 303 can rotate on the connecting frame 304. At this time, the upper and lower rotating frames 303 will fit on the surface of the transmission rod 202 and are located in the middle of the lower top plate 205. When the rotating frame 303 at the top rotates, the long rod will squeeze the sliding plate so that the sliding plate blocks the discharge port of the conical cylinder 203, which is convenient for the lower top plate 205 and the upper top plate 204 to squeeze the sludge. Then, when the lower top plate 205 moves downward, the sliding plate is subjected to the gravity of the sludge inside the conical cylinder 203, and the sliding plate will push the rotating frame 303 at the top to rotate through the long rod. When the rotating frame 303 at the top rotates, the connecting rod 302 will make the two rotating frames 303 respectively fit the side walls of the upper top plate 204 and the lower top plate 205. Then, when the motor drives the transmission rod 202 to rotate, the rotating transmission rod 202 will drive the rotating frame 303 to rotate synchronously. When the rotating frame 303 rotates on the side walls of the lower top plate 205 and the upper top plate 204, the rotation of the rotating frame 303 will make the turntable at one end of the transmission rod 2 305 contact the side walls of the lower top plate 205 and the upper top plate 204 and drive the transmission rod 2 305 to rotate. When the transmission rod 2 305 rotates, it will drive multiple fixed sleeves 401 to move back and forth. When the fixed sleeve 401 moves downward, the vibration plate 403 at the bottom of the fixed sleeve 401 will squeeze the mud cakes on the lower top plate 205 and the upper top plate 204. When the vibration plate 403 squeezes the mud cake, the reaction force generated by the mud cake will push the vibration plate 403 and the sliding shaft 404 to rise. At this time, the sliding shaft 404 will squeeze the spring block 402. After rising a certain distance, the sliding shaft 404 will enter the opening at the bottom of the spring block 402. At this time, the spring block 402 will be hit by the elastic force of the sandalwood on the top to hit the sliding shaft 404 and transmit it to the vibration plate 403, so that the vibration plate 403 will shake the mud cake apart and push the mud cake to the blocking door 105 under the vibration of the rotating frame 303. Through the vibration of the vibration plate 403 and the rotation of the conical cylinder 203, blockage can be avoided during mud and water separation, and the shutdown for cleaning can be reduced. While improving the cleaning efficiency, the subsequent separation efficiency will also be improved, saving separation time.

[0031] Then, when the transmission rod 202 drives the conical cylinder 203 to rotate, the rotation of the transmission rod 202 will drive the arc sleeve 208 to rotate. When the arc sleeve 208 rotates, it will continuously squeeze the raised ring 504. After being squeezed, the raised ring 504 will move downward on the surface of the vibration sleeve 501. When the raised ring 504 moves downward, it will push the swing shaft 506 to rotate through the middle rod 505. When the swing shaft 506 rotates, it will fit the inner wall of the conical cylinder 203. Then, when the conical cylinder 203 rotates, it will drive the rotating sleeve 601 and the turntable 2 on the spiral shaft 603 to rotate. When the turntable 2 rotates, it will drive the spiral cylinder 604 to rotate. When the spiral cylinder 604 rotates, it will The through ring 605 draws the gas at the opening of the transmission rod 202 into the swing shaft 506. When the gas enters the swing shaft 506, the gas will be accelerated by the spiral structure on the spiral shaft 603. Then, the fast-flowing gas will enter the one-way port 602 through the circular hole inside the swing shaft 506 and be ejected. At this time, the ejection of gas can generate a certain airflow pressure, which helps to push the moisture in the sludge to flow to the water outlet of the conical cylinder, thereby accelerating the separation speed of the moisture. At the same time, the rotation of the rotating sleeve 601 can squeeze the sludge at different positions on the conical cylinder 203, so that the moisture in the sludge can be squeezed out more fully, further enhancing the separation effect of this device and improving the use efficiency.

[0032] When the raised ring 504 is squeezed by the arc sleeve 208 and moves downward, the movement of the raised ring 504 will drive the spring disk 703 to move downward. When the spring disk 703 moves downward, it will push the curved tube 701 through the rotating tube 702, so that the curved tube 701 rotates on the outer ring 503. When the curved tube 701 rotates, it will fit the inner wall of the conical cylinder 203. When the conical cylinder 203 drives the sludge to rotate, the curved shape of the curved tube 701 can effectively guide the sludge on the inner wall of the conical cylinder 203 to flow downward along a specific path, reducing the accumulation and residence time of the sludge on the inner wall of the conical cylinder 203, thereby improving the overall sludge separation efficiency. In the process of the curved tube 701 fitting the inner wall, its own shape can play a certain scraping role, which can clean the sludge on the inner wall of the conical cylinder 203, so that less sludge remains on the inner wall, thereby maintaining the good filtering performance of the conical cylinder 203.
