Description

Technical Field

[0001] The present invention relates to the technical field of sludge separation, and particularly to a sewage sludge separation device and a separation method thereof. Background Technique

[0002] Sewage sludge is the accumulated solid sediment separated from various types of water, which is wet or mixed with liquid components and is the product of natural or artificial treatment processes. The sewage generated during the production process of urban sewage, water treatment plants, and industrial wastewater treatment stations contains a large amount of sludge. When treating sewage containing sludge, it is necessary to separate the sewage and sludge first;

[0003] Generally, when separating sludge from muddy water, most of them achieve the separation effect through the method of gravity plus precipitation. Since the traditional method mainly relies on natural gravity to precipitate sludge during the separation of muddy water from sludge, the separation process is relatively slow, and it takes a long time to achieve effective separation of muddy water, resulting in a large amount of time spent on separating muddy water, low separation efficiency of sludge, and affecting the overall separation efficiency.

[0015] Further, a method for using a sewage sludge separation device, the sewage sludge separation device, the method includes the following steps

[0016] S1: First, connect the water inlet on the top of the top cover to the pipeline for transporting the sludge to be treated. Then start the motor. When the motor works, it will drive the transmission rod and the conical cylinder to rotate. When the conical cylinder rotates, it will generate an outward centrifugal force on the sludge entering the main body, so that the sludge can adhere to the inner wall of the conical cylinder. At the same time, under the action of the centrifugal force, the water in the sludge can be quickly and effectively separated.

[0017] S2: Then the sludge will fall between the lower top plate and the upper top plate. Then the rotation of the conical cylinder will also drive the tooth shaft to rotate and cause the lower top plate to move upward. When the lower top plate moves upward, it will squeeze the sludge, so that the sludge is further separated from the water. Then the water outlet pipe can be opened to discharge the water.

[0018] S3: At the same time, the transmission rod will also drive the conical cylinder to push the sludge on the lower top plate to the sealing door and squeeze the sealing door. After being squeezed, the sealing door will push the spring rod. At this time, the conical cylinder will push the sludge into the space between the discharge door and the sealing door. Then the staff only needs to open the discharge door to process the sludge.

[0019] The present invention has the following beneficial effects:

[0020] 1. In this invention, first connect the water inlet at the top of the top cover to the pipeline for transporting the sludge to be treated. Then start the motor. When the motor operates, it drives the transmission rod and the conical cylinder to rotate. When the conical cylinder rotates, it generates a centrifugal force that throws the sludge entering the main body outward, causing the sludge to adhere tightly to the inner wall of the conical cylinder. At the same time, under the action of the centrifugal force, the water in the sludge can be quickly and effectively separated, and the water is thrown out through the filter holes. Then the sludge with some 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 drives the gear shaft to rotate through the teeth on its outer surface. When the gear shaft rotates, the insertion rod on its outer surface rotates in the double-threaded groove inside the double-threaded sleeve, and drives the lower top plate to reciprocate inside the inner sleeve through the double-threaded sleeve. When the lower top plate moves upward, the moving lower top plate drives the sludge on it to rise and adhere to the bottom of the upper top plate. Then when the lower top plate continues to rise, the lower top plate drives the sludge to squeeze the upper top plate. Since the upper top plate is fixed, when the lower top plate drives the sludge to squeeze the upper top plate, the reaction force generated by the upper top plate acts on the sludge, causing the sludge to be squeezed from both sides. At this time, the sludge will become a mud cake after being squeezed, and the remaining water will be discharged outward through the filter holes on the inner sleeve. When the mud and water are separated by the extrusion of the lower top plate and the centrifugal force generated by the rotation of the conical cylinder, a double filtration system is formed, which increases the speed of water passing through the filter screen and the filter plate. Compared with the traditional gravity sedimentation separation method, the separation time is greatly shortened, thus improving the separation efficiency of sewage sludge as a whole.

[0021] 2. In the present invention, when the lower top plate is pulled upward by the bidirectional screw sleeve inside the inner sleeve, the moving lower top plate will squeeze the rotating frame at the bottom. When the rotating frame is squeezed, it will rotate on the surface of the transmission rod. When the rotating frame rotates, it will push the C-shaped plate to move upward inside the rectangular groove through the connecting rod. When the C-shaped plate moves upward, it will pull the top rotating frame through the connecting rod at the top, causing the rotating frame to rotate on the connecting frame. At this time, the upper and lower rotating frames will fit on the surface of the transmission rod and be located in the gap in the middle of the lower top plate. When the top rotating frame rotates, it will squeeze the sliding disk through the long rod, causing the sliding disk to block the material outlet of the conical cylinder, facilitating the squeezing of the sludge by the lower top plate and the upper top plate. After that, when the lower top plate moves downward, when the sliding disk is affected by the gravity of the sludge inside the conical cylinder, the sliding disk will push the top rotating frame to rotate through the long rod. When the top rotating frame rotates, it will drive the two rotating frames to fit on the side walls of the upper top plate and the lower top plate respectively through the connecting rod. Then, when the motor drives the transmission rod to rotate, the rotating transmission rod will drive the rotating frame to rotate synchronously. When the rotating frame rotates on the side walls of the lower top plate and the upper top plate, the rotation of the rotating frame will cause the turntable at one end of the transmission rod two to contact the side walls of the lower top plate and the upper top plate and drive the transmission rod two to rotate. When the transmission rod two rotates, it will drive a plurality of fixed sleeves to move reciprocally. When the fixed sleeve moves downward, the vibrating plate at the bottom of the fixed sleeve will squeeze the mud cake on the lower top plate and the upper top plate. When the vibrating plate squeezes the mud cake, the reaction force generated by the mud cake will push the vibrating plate and the sliding shaft upward. At this time, the sliding shaft will squeeze the spring block. When it rises a certain distance, the sliding shaft will enter the opening at the bottom of the spring block. At this time, the spring block will be elastically impacted by the sandalwood at the top on the sliding shaft and transmit it to the vibrating plate, causing the vibrating plate to disperse the mud cake and push the mud cake to the blocking door under the vibration of the rotating frame. Through the vibration of the vibrating plate and the rotation of the conical cylinder, it is possible to avoid blockage during the separation of mud and water, and at the same time reduce the situation of shutdown cleaning, improve the cleaning efficiency and the subsequent separation efficiency, and save the separation time.

[0022] 3. In the present invention, when the transmission rod drives the conical cylinder to rotate later, the rotation of the transmission rod will drive the arc-shaped sleeve to rotate. When the arc-shaped sleeve rotates, it will continuously squeeze the convex ring. After being squeezed, the convex ring will move downward on the surface of the vibration sleeve. When the convex ring moves downward, it will push the swing shaft to rotate through the middle rod. When the swing shaft rotates, it will fit against the inner wall of the conical cylinder. Then, when the conical cylinder rotates, it will drive the rotating sleeve and the turntable two on the spiral shaft to rotate. When the turntable two rotates, it will drive the spiral cylinder to rotate. When the spiral cylinder rotates, it will draw the gas at the opening of the transmission rod into the swing shaft through the connecting ring. When the gas enters the swing shaft, the gas will be affected by the spiral structure on the spiral shaft and thus accelerate its flow. Then, the rapidly flowing gas will enter the one-way port through the round holes inside the swing shaft and be ejected. At this time, the ejection of the gas can generate a certain airflow pressure to assist in pushing the water in the sludge towards the water outlet holes of the conical cylinder, accelerating the water separation speed. At the same time, the rotation of the rotating sleeve can squeeze the sludge at different positions on the conical cylinder, enabling the water in the sludge to be more fully squeezed out, further enhancing the separation effect of this device and improving the usage efficiency.

[0023] 4. In the present invention, when the convex ring moves downward under the extrusion of the arc-shaped sleeve, the movement of the convex ring will drive the spring disc to move downward. When the spring disc moves downward, it will push the curve tube through the rotating tube, causing the curve tube to rotate on the outer ring. When the curve tube rotates, it will fit against the inner wall of the conical cylinder. When the conical cylinder drives the sludge to rotate, through the shape of the curve of the curve tube, it can effectively guide the sludge on the inner wall of the conical cylinder to flow downward along a specific path, reducing the accumulation and residence time of the sludge on the inner wall of the conical cylinder, thereby improving the overall sludge separation efficiency. And during the process of the curve tube fitting against the inner wall, its own shape can play a certain scraping role, being able to clean the sludge on the inner wall of the conical cylinder, resulting in less sludge residue on the inner wall, thus maintaining the good filtering performance of the conical cylinder.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

When the motor works, it will drive the transmission rod 202 and the conical cylinder 203 to rotate. When the conical cylinder 203 rotates, it will generate a centrifugal force that throws the sludge entering the main body 1 outward, so that the sludge can adhere to the inner wall of the conical cylinder 203. At the same time, under the action of the centrifugal force, the water in the sludge can be quickly and effectively separated, and the water is thrown out through the filter holes.

When the second turntable rotates, it will drive the spiral cylinder 604 to rotate. When the spiral cylinder 604 rotates, it will draw the gas at the opening of the transmission rod 202 into the swing shaft 506 through the communication ring 605.

One end of the plurality of rotating tubes 702 away from the curved tube 701 is rotatably connected to a spring disc 703. One end of the spring disc 703 away from the rotating tube 702 is fixedly connected to the side wall of the top cover 101. The inner wall of the spring disc 703 is fixedly connected to the convex ring 504. When the convex ring 504 is squeezed by the arc-shaped sleeve 208 and moves downward, the movement of the convex ring 504 will drive the spring disc 703 to move downward. When the spring disc 703 moves downward, it will push the curved tube 701 through the rotating tube 702, causing the curved tube 701 to rotate on the outer ring 503. When the curved tube 701 rotates, it will fit on the inner wall of the conical cylinder 203.

[0049] A method for using a sewage sludge separation device, the sewage sludge separation device, the method comprising the following steps,

[0050] S1: First, connect the water inlet at the top of the top cover 101 to the pipeline for transporting the sludge to be treated. Then start the motor. When the motor works, 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 closely adhere 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;

[0051] S2: Then the sludge will fall between the lower top plate 205 and the upper top plate 204. Then the rotation of the conical cylinder 203 will also drive the gear shaft 207 to rotate and cause the lower top plate 205 to move upward. When the lower top plate 205 moves upward, it will squeeze the sludge, so that the sludge is further separated from the water. Then the water outlet pipe 102 can be opened to discharge the water;

[0052] S3: 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 to the blocking door 105 and squeeze the blocking door 105. After the blocking door 105 is squeezed, it will push the spring rod 104. At this time, the conical cylinder 203 will push the sludge into the space between the discharge door 103 and the blocking door 105. Then the staff only needs to open the discharge door 103 to treat the sludge.

[0053] In use, first connect the water inlet at the top of the top cover 101 to the pipeline for transporting the sludge to be treated. Then start the motor. When the motor works, it will drive the transmission rod 202 and the conical cylinder 203 to rotate. When the conical cylinder 203 rotates, it will generate a centrifugal force that throws the sludge entering the main body 1 outward, causing the sludge to cling to the inner wall of the conical cylinder 203. At the same time, under the action of the centrifugal force, the water in the sludge can be quickly and effectively separated. Then the sludge will fall between the lower top plate 205 and the upper top plate 204. Then the rotation of the conical cylinder 203 will also drive the gear shaft 207 to rotate and cause the lower top plate 205 to move upward. When the lower top plate 205 moves upward, it will squeeze the sludge to further separate the sludge from the water. Then the water outlet pipe 102 can be opened to drain 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 the blocking door 105 is squeezed, it will push the spring rod 104. At this time, the conical cylinder 203 will push the sludge into the space between the discharge door 103 and the blocking door 105. Then the staff only needs to open the discharge door 103 to treat the sludge.

[0054] First, connect the water inlet at the top of the top cover 101 to the pipeline for transporting the sludge to be treated. Then, start the motor. When the motor works, it will drive the transmission rod 202 and the conical cylinder 203 to rotate. When the conical cylinder 203 rotates, it will generate a centrifugal force that throws the sludge entering the main body 1 outward, causing the sludge to adhere tightly to the inner wall of the conical cylinder 203. At the same time, under the action of the centrifugal force, the water in the sludge can be quickly and effectively separated, and the water is thrown out through the filter holes. Then, 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 through the insertion rod on the outer surface in the double-threaded groove inside the double-threaded sleeve 206, and drive the lower top plate 205 to reciprocate inside the inner sleeve 201 through the double-threaded sleeve 206. When the lower top plate 205 moves upward, the moving lower top plate 205 will drive the sludge on the lower top plate 205 to rise and adhere to 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 sludge to squeeze the upper top plate 204. Since the upper top plate 204 is fixed, when the lower top plate 205 drives the sludge to squeeze the upper top plate 204, the reaction force generated by the upper top plate 204 will act on the sludge, causing the sludge to be squeezed on both sides. At this time, the sludge will become a mud cake after being squeezed, and the remaining water will be discharged outward through the filter holes on the inner sleeve 201. When the mud and water are separated by the extrusion of the lower top plate 205 and the centrifugal force generated by the rotation of the conical cylinder 203, a double filtration system is formed, increasing the speed of water passing through the filter screen and the filter plate. Compared with the traditional gravity sedimentation separation method, the separation time is greatly shortened, thus overall improving the separation efficiency of sewage sludge.

[0055] When the lower top plate 205 is pulled upward inside the inner sleeve 201 by the double-threaded sleeve 206, the moving lower top plate 205 will squeeze the bottom rotating frame 303. 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 top rotating frame 303 through the connecting rod 302 at the top, causing the rotating frame 303 to 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 be located in the gap in the middle of the lower top plate 205. When the top rotating frame 303 rotates, it will squeeze the sliding disk through the long rod, causing the sliding disk to block the material outlet of the conical cylinder 203, facilitating the extrusion of the sludge by the lower top plate 205 and the upper top plate 204. After that, when the lower top plate 205 moves downward, when the sliding disk is affected by the gravity of the sludge inside the conical cylinder 203, the sliding disk will push the top rotating frame 303 to rotate through the long rod. When the top rotating frame 303 rotates, it will make the two rotating frames 303 fit on the side walls of the upper top plate 204 and the lower top plate 205 respectively through the connecting rod 302. After that, 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 cause the turntable at one end of the transmission rod two 305 to contact the side walls of the lower top plate 205 and the upper top plate 204 and drive the transmission rod two 305 to rotate. When the transmission rod two 305 rotates, it will drive multiple fixed sleeves 401 to move reciprocally. When the fixed sleeve 401 moves downward, the vibrating plate 403 at the bottom of the fixed sleeve 401 will squeeze the mud cake on the lower top plate 205 and the upper top plate 204. When the vibrating plate 403 squeezes the mud cake, the reaction force generated by the mud cake will push the vibrating plate 403 and the sliding shaft 404 to rise. At this time, the sliding shaft 404 will squeeze the spring block 402. When it rises 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 elastically impacted by the sandalwood at the top on the sliding shaft 404 and transmitted to the vibrating plate 403, causing the vibrating plate 403 to disperse the mud cake and push the mud cake to the blocking door 105 under the vibration of the rotating frame 303. Through the vibration of the vibrating plate 403 and the rotation of the conical cylinder 203, it is possible to avoid blockage during the separation of mud and water. At the same time, it can also reduce the situation of shutdown for cleaning, improve the cleaning efficiency while also improving the subsequent separation efficiency and saving the separation time.

[0056] After the drive rod 202 drives the conical cylinder 203 to rotate, the rotation of the drive rod 202 will drive the arc-shaped sleeve 208 to rotate. When the arc-shaped 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 intermediate rod 505. When the swing shaft 506 rotates, it will fit against the inner wall of the conical cylinder 203. Then, when the conical cylinder 203 rotates, it will drive the rotating sleeve 601 and the second turntable on the spiral shaft 603 to rotate. When the second turntable rotates, it will drive the spiral cylinder 604 to rotate. When the spiral cylinder 604 rotates, it will draw the gas at the opening of the drive rod 202 into the swing shaft 506 through the communication ring 605. When the gas enters the swing shaft 506, the gas will be accelerated by the spiral structure on the spiral shaft 603. Then, the rapidly flowing gas will enter the one-way port 602 through the round hole inside the swing shaft 506 and be ejected. At this time, the ejection of the gas can generate a certain airflow pressure to assist in pushing the water in the sludge towards the water outlet hole of the conical cylinder, accelerating the water separation speed. At the same time, the rotation of the rotating sleeve 601 can squeeze the sludge at different positions on the conical cylinder 203, making the water in the sludge more fully squeezed out, further enhancing the separation effect of this device and improving the use efficiency.

[0057] When the raised ring 504 is squeezed by the arc-shaped sleeve 208 and moves downward, the movement of the raised ring 504 will drive the spring disc 703 to move downward. When the spring disc 703 moves downward, it will push the curve tube 701 through the rotating tube 702, causing the curve tube 701 to rotate on the outer ring 503. When the curve tube 701 rotates, it will fit against the inner wall of the conical cylinder 203. When the conical cylinder 203 drives the sludge to rotate, the shape of the curve of the curve 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. And during the process of the curve tube 701 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 cylinder 203, making the sludge residue on the inner wall less, so as to maintain the good filtering performance of the conical cylinder 203.
