Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a sludge pumping mechanism for wastewater treatment. Background Technology

[0002] Currently, wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse, and the sludge removal process is an essential procedure in wastewater treatment projects.

[0003] In related technologies, a sludge removal mechanism for a wastewater treatment device includes a sludge removal device and a temporary storage tank. The sludge removal device includes a sludge removal pipe, a sewage pump, and a conveying pipe. The sewage pump is fixedly connected to the temporary storage tank. The inlet end of the sewage pump is connected to one end of the sludge removal pipe, and the outlet end of the sewage pump is connected to one end of the conveying pipe. The other end of the conveying pipe is connected to the inside of the temporary storage tank. Multiple rollers are fixedly connected to the bottom of the temporary storage tank, and the rollers are evenly distributed at the bottom of the tank. One end of the sludge removal pipe is inserted into the wastewater, and the sewage pump is started to draw the sludge through the sludge removal pipe into the conveying pipe, which then transports it to the temporary storage tank for temporary storage.

[0004] Regarding the aforementioned technologies, the sludge pumping device pumps the sewage along with the sludge into the temporary storage tank, which causes the temporary storage tank to fill up quickly. As a result, the staff will have to clean the temporary storage tank multiple times, increasing their workload and reducing their work efficiency. Summary of the Invention

[0005] To reduce the workload of staff, the present invention provides a sludge pumping mechanism for sewage treatment.

[0006] The present invention provides a sludge removal mechanism for wastewater treatment, which adopts the following technical solution:

[0007] A sludge removal mechanism for wastewater treatment includes a temporary storage tank and a sludge removal device. The sludge removal device includes a sludge removal pipe, a sewage pump, and a delivery pipe. The sludge removal pipe is connected to the inlet end of the sewage pump. One end of the delivery pipe is connected to the outlet end of the sewage pump, and the other end is connected to the interior of the temporary storage tank. The temporary storage tank is connected to a forward movement device that drives the temporary storage tank to move. The sewage pump is connected to the forward movement device. A first partition is connected to the inner wall of the temporary storage tank. The first partition separates the temporary storage tank into a liquid storage chamber and a sludge storage chamber. The upper half of the liquid storage chamber and the sludge storage chamber are partially connected. The liquid storage chamber is connected to an outlet pipe, and the sludge storage chamber is connected to a sludge outlet pipe.

[0008] The top of the liquid storage chamber is equipped with a separation device for separating sewage and sludge. The separation device includes a chain conveyor belt for transporting sludge into the sludge storage chamber and a drive assembly for driving the chain conveyor belt. The drive assembly is connected to the temporary storage tank. The chain conveyor belt covers the liquid storage chamber, and the outlet end of the conveying pipe is located above the chain conveyor belt.

[0009] By adopting the above technical solution, when sludge needs to be removed from sewage, the sewage pump is started, bringing the inlet of the sludge removal pipe close to the sludge. The sewage pump then sends the sludge and sewage together through the conveyor pipe into the temporary storage pipe for temporary storage. After the sludge and water are discharged from the outlet of the conveyor pipe, they fall onto the chain conveyor belt. The drive assembly is then activated, which transports the sludge and water towards the sludge storage chamber. During the movement of the chain conveyor belt, the sludge and water are separated. The water falls into the liquid storage chamber, while the sludge is transported to the sludge storage chamber for temporary storage. Separating the sewage and sludge increases the amount of sludge that can be carried, reduces the number of times the temporary storage pipe is filled, and thus reduces the number of times workers need to clean the temporary storage tank, reducing the workload of workers and improving their work efficiency. The forward device drives the sludge removal mechanism forward or backward, facilitating the removal of sludge from the sewage. The liquid outlet pipe is used to discharge the sewage temporarily stored in the liquid storage chamber. The sludge outlet pipe is used to discharge the sludge temporarily stored in the sludge storage chamber.

[0010] Preferably, the driving assembly includes a motor, a first roller, and a second roller. The motor is connected to the temporary storage tank. The first roller and the second roller are arranged horizontally and parallel to each other. The first roller and the second roller are rotatably connected to the temporary storage tank. The second roller is fixedly connected to the motor. The chain conveyor belt is sleeved on the first roller and the second roller and abuts against both the first roller and the second roller. The separation device also includes a linkage assembly that drives the first roller and the second roller to move synchronously. A placement cavity is opened in the side wall of the temporary storage tank, and the linkage assembly is disposed in the placement cavity.

[0011] By adopting the above technical solution, the motor is started, which drives the second roller to rotate. The second roller, through the linkage assembly, drives the first roller to rotate. The first and second rollers together drive the chain conveyor belt. The placement cavity isolates the linkage assembly from water and silt, ensuring the normal working condition of the linkage assembly.

[0012] Preferably, the inner wall of the temporary storage tank is connected to a baffle to prevent sludge from falling from the gap between the chain conveyor belt and the temporary storage tank. Multiple baffles are provided, with the side of the baffle away from the temporary storage tank located above the chain conveyor belt. The baffles are inclined and slope downward from one end near the temporary storage tank to the other end.

[0013] By adopting the above technical solution, the baffle reduces the possibility of sludge falling into the storage pipe through the gap between the chain conveyor belt and the temporary storage tank. The inclined baffle facilitates the sludge's detachment, reduces the possibility of sludge remaining on the baffle, and thus reduces the workload of staff in cleaning the temporary storage pipe.

[0014] Preferably, the inner wall of the temporary storage tank is connected to a second partition, which separates the sludge storage chamber into a transition chamber and a temporary storage chamber. The transition chamber is close to the liquid storage chamber, and a filter assembly for further separating sludge and sewage is provided in the transition chamber. The filter assembly is connected to the temporary storage tank, the first partition, and the second partition.

[0015] By adopting the above technical solution, the chain conveyor belt transports the sludge to the filter assembly in the transition chamber, where the filter assembly separates the water from the sludge again, further increasing the amount of sludge it can hold, reducing the number of times the temporary storage tube needs to be filled, thereby reducing the workload of the workers and improving their work efficiency. The sludge temporarily accumulates on the filter assembly and is then transported to the temporary storage chamber by the transport assembly.

[0016] Preferably, the filtration assembly includes a first filter plate and a second filter plate. The end wall of the first filter plate is connected to the end wall of the second filter plate. The side wall of the first filter plate away from the second filter plate is connected to the first partition. The side wall of the second filter plate away from the first filter plate is connected to the second partition. The end walls of the first filter plate and the second filter plate on the same side are connected to the inner wall of the temporary storage tank. The first filter plate and the second filter plate are both inclined. The first filter plate is inclined upward from one end closer to the second filter plate to the other end, and the second filter plate is inclined upward from one end closer to the first filter plate to the other end.

[0017] By adopting the above technical solution, the chain conveyor belt transports the sludge to the first and second filter plates, which then filter out the remaining wastewater from the sludge. Both the first and second filter plates are inclined, increasing the contact area between the sludge and the filter plates, thereby increasing the area from which wastewater is filtered and improving filtration efficiency.

[0018] Preferably, the temporary storage tank is connected to a striking device, which includes two sets of striking components and a synchronization component that drives the two sets of striking components to move synchronously with the second roller. The two sets of striking components correspond one-to-one with the first filter plate and the second filter plate. The striking components are disposed below the first filter plate and the second filter plate. Each striking component includes a rotating shaft, a fixed cylinder, a moving rod, a spring, and a striking block. The rotating shaft is rotatably connected to the temporary storage tank, and both rotating shafts are connected to the synchronization component. One end of the fixed cylinder is connected to the outer peripheral wall of the rotating shaft. The moving rod extends into the fixed cylinder and is slidably connected to the fixed cylinder. The spring is located inside the fixed cylinder, with one end connected to the fixed cylinder and the other end connected to the moving rod. The striking block is rotatably connected to the moving rod. When the striking block abuts against the first filter plate or the second filter plate, the striking block strikes the first filter plate or the second filter plate.

[0019] By adopting the above technical solution, the second roller rotates while driving the synchronous component to move. The synchronous component drives two rotating shafts to rotate, and the rotating shafts drive the fixed cylinder connected to them to rotate along the axis of the rotating shafts. The fixed cylinder drives the moving rod to rotate, and the moving rod drives the striking block to rotate. During the rotation of the fixed cylinder, the spring is stretched, and the striking block strikes the first or second filter plate. As the rotating shaft continues to rotate, the spring slowly contracts, and the striking block slides against the first or second filter plate. Then, the striking block moves away from the first or second filter plate again, and the spring is stretched again. This repeated stretching and contraction of the spring and the striking block striking the first or second filter plate reduces the possibility of clogging of the first or second filter plate. The striking block and the moving rod are rotatably connected, reducing the possibility of wear between the striking block and the first or second filter plate and increasing the service life of the striking block.

[0020] Preferably, the synchronization component is located within the placement cavity, with one end of the rotating shaft extending through the temporary storage tank into the placement cavity. The synchronization component includes a first sprocket, a second sprocket, a third sprocket, and a synchronization chain. The first sprocket is connected to the second roller, and the second sprocket and the third sprocket are respectively connected to the two rotating shafts. The first sprocket is connected to the rotating shaft to which it is connected, and the second sprocket is connected to the rotating shaft to which it is connected. The synchronization chain is sleeved on the first sprocket, the second sprocket, and the third sprocket, and the synchronization chain meshes with all three sprockets.

[0021] By adopting the above technical solution, the second roller drives the first sprocket to rotate, the first sprocket drives the second sprocket and the third sprocket to rotate through the synchronous chain, and the second sprocket and the third sprocket drive the two rotating shafts to rotate.

[0022] Preferably, the second partition is connected to a transport assembly for transporting sludge from the transition chamber to the temporary storage chamber. The transport assembly includes a suction pump, a suction pipe, and a transport pipe. The suction pump is connected to the temporary storage tank. The inlet end of the suction pump is connected to the suction pipe, and the outlet end of the suction pump is connected to the transport pipe. The suction pipe is connected to the transition chamber and is located on the side of the first filter plate closer to the second filter plate. The transport pipe is connected to the temporary storage chamber.

[0023] By adopting the above technical solution, when the sludge in the transition chamber is stored to a certain height, the suction pump is started. The suction pump sucks the sludge on the first filter plate and the second filter plate into the suction pipe, and then the suction pump outputs it into the transport pipe. The sludge in the transport pipe is transported to the temporary storage chamber for temporary storage.

[0024] Preferably, the second filter plate is connected to a vibration sensor, the vibration sensor is electrically connected to a control module, and the control module is electrically connected to the suction pump.

[0025] By adopting the above technical solution, when the striking block strikes the second filter plate, if the amount of sludge on the second filter plate is small, the vibration frequency of the second filter plate is large; if the amount of sludge on the second filter plate is large, the vibration frequency of the second filter plate is small. The vibration sensor detects the vibration of the second filter plate. When the maximum vibration frequency of the second filter plate decreases to a certain value, the vibration sensor transmits an electrical signal to the control module. After receiving the electrical signal, the control module transmits the electrical signal to the suction pump, and the suction pump starts.

[0026] Preferably, the forward advancing device includes a base plate and rollers, the temporary storage tank is fixedly connected to the top of the base plate, and multiple rollers are provided, each of which is fixedly connected to the base plate.

[0027] By adopting the above technical solution, the rollers drive the bottom plate to move, and the bottom plate drives the temporary storage tank to move, which facilitates the continuous extraction of sludge.

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. When it is necessary to remove sludge from sewage, start the sewage pump and bring the inlet of the sludge removal pipe close to the sludge. The sewage pump will send the sludge and sewage together through the conveyor pipe into the temporary storage pipe for temporary storage. After the sludge and water are discharged from the conveyor pipe, they fall onto the chain conveyor belt. The chain conveyor belt separates the sludge and water, with the water falling into the liquid storage chamber. The drive component drives the chain conveyor belt to transport the sludge to the sludge storage chamber. After separating the sewage and sludge, the amount of sludge that can be carried is increased, reducing the number of times the temporary storage pipe is filled. This reduces the number of times the temporary storage tank needs to be cleaned by the staff, thus reducing the workload of the staff and improving their work efficiency.

[0030] 2. The sludge storage chamber is divided into a transition chamber and a temporary storage chamber. The first and second filter plates in the transition chamber further separate the sludge and water, which further increases the amount of sludge that can be carried, reduces the number of times the temporary storage tube is filled, and thus reduces the number of times the staff cleans the temporary storage tank, thereby reducing the workload of the staff.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] A sludge pumping mechanism for wastewater treatment, as described in the following figure Figure 1 and Figure 2The system includes a forward advancing device 1, a temporary storage tank 2, a sludge pumping device 3, and a separation device 4. The temporary storage tank 2 is connected to the forward advancing device 1, which drives the sludge pumping mechanism. The sludge pumping device 3 is connected to the temporary storage tank 2 and is used to pump sludge and transport it to the temporary storage tank 2 for temporary storage. The inner wall of the temporary storage tank 2 is connected to a first partition 21, which separates the temporary storage tank 2 into a liquid storage chamber and a sludge storage chamber, with the upper parts of the liquid storage chamber and the sludge storage chamber partially connected. The separation device 4 includes a drive assembly and a chain conveyor belt 44. The drive assembly is connected to the temporary storage tank 2, and the chain conveyor belt 44 is connected to the drive assembly, which drives the chain conveyor belt 44 to move. The chain conveyor belt 44 covers the top of the liquid storage chamber and is used to separate the water and sludge pumped by the sludge pumping device 3, and transport the sludge to the sludge storage chamber for temporary storage. The liquid storage chamber is connected to a liquid outlet pipe 24, and the sludge storage chamber is connected to a sludge outlet pipe 25. After the sludge pumping device 3 pumps out water and sludge and sends it into the temporary storage tank 2, the chain conveyor belt 44 reduces the number of times the temporary storage tank 2 is filled, thereby reducing the number of times the staff need to clean the temporary storage tank 2 and reducing the workload of the staff.

[0040] Reference Figure 1 The forward movement device 1 includes a base plate 11 and rollers 12. The base plate 11 is horizontally positioned, and the bottom of the base plate 11 is fixedly connected to the rollers 12. There are four rollers 12, which are located at the four corners of the base plate 11. The temporary storage tank 2 is fixedly connected to the base plate 11.

[0041] Reference Figure 2 and Figure 3 A baffle 23 is fixedly connected to the inner wall of the temporary storage tank 2. The side of the baffle 23 away from the temporary storage tank 2 is close to the top of the chain conveyor belt 44. Three baffles 23 are provided, located on both sides and the beginning of the chain conveyor belt 44 in the conveying direction. The end of the baffle 23 away from the temporary storage tank 2 is above the chain conveyor belt 44. The baffle 23 is inclined, tilting downwards from the end closest to the temporary storage tank 2 to the other end. The baffle 23 reduces the possibility of sludge falling into the liquid storage pipe through the gap between the chain conveyor belt 44 and the temporary storage tank 2.

[0042] Reference Figure 1 The sludge removal device 3 includes a sludge removal pipe 31, a sewage pump 32, and a conveying pipe 33. The sewage pump 32 is fixedly connected to the base plate 11. The inlet end of the sewage pump 32 is connected to the outlet end of the sludge removal pipe 31, and the outlet end of the sewage pump 32 is connected to the inlet end of the conveying pipe 33. The outlet end of the conveying pipe 33 is connected to the interior of the temporary storage tank 2. The outlet end of the conveying pipe 33 is located above the chain conveyor belt 44.

[0043] Reference Figure 2The drive assembly includes a motor 41, a first roller 42, and a second roller 43. The motor 41 is fixedly connected to the outer wall of the temporary storage tank 2. Both the first roller 42 and the second roller 43 are horizontally arranged and parallel to each other. Both the first roller 42 and the second roller 43 are rotatably connected to the temporary storage tank 2. One end of the second roller 43 passes through the temporary storage tank 2 and is fixedly connected to the drive shaft of the motor 41. A chain conveyor belt 44 is fitted onto the first roller 42 and the second roller 43, and the chain conveyor belt 44 abuts against both the first roller 42 and the second roller 43.

[0044] Start motor 41, which drives the second roller 43 to rotate. The second roller 43 drives the first roller 42 to rotate through the linkage component 45. The first roller 42 and the second roller 43 together drive the chain conveyor belt 44 to move. The chain conveyor belt separates the sludge and water and transports the sludge to the sludge storage chamber.

[0045] Reference Figure 2 and Figure 3 The separation device 4 also includes a linkage component 45. A placement cavity is provided in the side wall of the temporary storage tank 2. The linkage component 45 is set in the placement cavity. One end of the first roller 42 and the second roller 43 on the same side both penetrate the temporary storage tank 2 and extend into the placement cavity. The linkage component 45 is connected to the first roller 42 and the second roller 43.

[0046] Reference Figure 2 To achieve the same purpose, the linkage component 45 can be configured with a chain and sprocket, a belt and pulley, etc. In this embodiment, a chain and sprocket combination is used. There are two sprockets, each corresponding to the first roller 42 and the second roller 43 respectively. The sprockets are fixedly connected to both rollers. The chain is sleeved on the two sprockets and meshes with them. The two sprockets and the chain work together to achieve synchronous movement of the first roller 42 and the second roller 43, which is used to transport the chain conveyor belt 44.

[0047] Reference Figure 3 and Figure 4 A second partition 22 is fixedly connected to the inner wall of the temporary storage tank 2, which separates the sludge storage chamber into a transition chamber and a temporary storage chamber. The transition chamber is close to the liquid storage chamber. A filter assembly 5 is installed in the transition chamber. The filter assembly 5 includes a first filter plate 51 and a second filter plate 52, with the end wall of the first filter plate 51 fixedly connected to the end wall of the second filter plate 52. Both the first filter plate 51 and the second filter plate 52 are inclined. The first filter plate 51 is inclined upward from one end near the second filter plate 52 to the other end, and the second filter plate 52 is inclined upward from one end near the first filter plate 51 to the other end.

[0048] Reference Figure 3The end wall of the first filter plate 51 away from the second filter plate 52 is fixedly connected to the first partition 21, and the end wall of the second filter plate 52 away from the first filter plate 51 is fixedly connected to the second partition 22. The end walls of the first filter plate 51 and the second filter plate 52 on the same side are fixedly connected to the inner wall of the temporary storage tank 2.

[0049] The chain conveyor belt 44 transports the sludge to the first filter plate 51 and the second filter plate 52, where the first filter plate 51 and the second filter plate 52 further filter the sewage in the sludge.

[0050] Reference Figure 3 The transition chamber is also connected to a liquid outlet pipe 24, the top of which is lower than the bottom of the first filter plate 51. The sludge outlet pipe 25 is connected to the temporary storage chamber and is located at the bottom of the temporary storage chamber. Both the sludge outlet pipe 25 and the two liquid outlet pipes 24 are fixedly connected to a switch valve (not shown in the figure), which can be a ball valve, butterfly valve, etc.

[0051] The outlet pipe 24, which is connected to the transition chamber, is used to discharge the sewage in the transition chamber, and the outlet pipe 24, which is connected to the storage chamber, is used to discharge the sewage in the storage chamber. The sludge storage chamber is used to discharge the sludge in the temporary storage chamber.

[0052] Reference Figure 2 The temporary storage tank 2 is connected to a striking device, which is located inside the transition chamber. The striking device includes a striking component 6 and a synchronization component 7. There are two sets of striking components 6, which correspond one-to-one with the first filter plate 51 and the second filter plate 52, respectively, and the striking components 6 are located below the first filter plate 51 and the second filter plate 52.

[0053] Reference Figure 4 and Figure 5 The striking component 6 includes a rotating shaft 61, a fixed cylinder 62, a moving rod 63, a spring 64, a mounting bracket 65, and a striking block 66. The rotating shaft 61 is horizontally arranged, and the length direction of the rotating shaft 61 is perpendicular to the direction of conveying sludge on the chain conveyor belt 44. Both ends of the rotating shaft 61 are rotatably connected to the temporary storage tank 2, and one end of the rotating shaft 61 passes through the temporary storage tank 2 and extends into the placement cavity.

[0054] Reference Figure 4 and Figure 5 The fixed cylinder 62 is fixedly connected to the rotating shaft 61. One end of the moving rod 63 extends into the fixed cylinder 62, and the other end is fixedly connected to the mounting bracket 65. The moving rod 63 is slidably connected to the fixed cylinder 62. The spring 64 is disposed inside the fixed cylinder 62, with one end fixedly connected to the fixed cylinder 62 and the other end fixedly connected to the moving rod 63. The striking block 66 is sleeved on the mounting bracket 65 and rotatably connected to the mounting bracket 65. When the striking block 66 strikes the first filter plate 51 or the second filter plate 52, the striking block 66 abuts against the first filter plate 51 or the second filter plate 52.

[0055] When the second roller 43 rotates, it drives the synchronous component 7 to move. The synchronous component 7 drives the two rotating shafts 61 to rotate. The rotating shafts 61 drive the fixed cylinder 62 connected to them to rotate along the axis of the rotating shafts 61. The fixed cylinder 62 drives the moving rod 63 to rotate. At this time, the spring 64 is stretched. The moving rod 63 drives the striking block 66 to rotate. The rotating shaft 61 continues to rotate. The spring 64 slowly contracts. The striking block 66 slides against the first filter plate 51 or the second filter plate 52. The striking block 66 disengages from the first filter plate 51 or the second filter plate 52. The spring 64 is stretched again.

[0056] Reference Figure 4 The synchronization component 7 is disposed within the placement cavity. The synchronization component 7 includes a first sprocket 71, a second sprocket 72, a third sprocket 73, and a synchronization chain 74. The first sprocket 71 is fixedly connected to the second roller 43. The first sprocket 71 and the second sprocket 72 are respectively connected to two rotating shafts 61. The first sprocket 71 is coaxially and fixedly connected to the rotating shaft 61 to which it is connected, and the second sprocket 72 is coaxially and fixedly connected to the rotating shaft 61 to which it is connected. The synchronization chain 74 is sleeved on the first sprocket 71, the second sprocket 72, and the third sprocket 73, and the synchronization chain 74 meshes with all three sprockets.

[0057] The second roller 43 drives the first sprocket 71 to rotate. The first sprocket 71 drives the second sprocket 72 and the third sprocket 73 to rotate via the synchronous chain 74. The second sprocket 72 and the third sprocket 73 drive the two rotating shafts 61 to rotate.

[0058] Reference Figure 2 and Figure 4 The second filter plate 52 is connected to a vibration sensor 8, which is electrically connected to a control module. The temporary storage tank 2 is connected to a transport assembly 9, which includes a suction pump 91, a suction tube 92, and a transport pipe 93. The suction pump 91 is fixedly connected to the temporary storage tank 2 and electrically connected to the control module. One end of the suction tube 92 extends into the temporary storage tank 2, communicates with the transition chamber, and is located on the side of the first filter plate 51 closest to the second filter plate 52. The other end of the suction tube 92 communicates with the inlet end of the suction pump 91. One end of the transport pipe 93 communicates with the outlet end of the suction pump 91, and the other end extends into the temporary storage tank 2 and communicates with the temporary storage chamber.

[0059] When the striking block 66 strikes the second filter plate 52, if the amount of sludge stored on the second filter plate 52 is large, the vibration frequency of the second filter plate 52 is relatively low. The vibration sensor 8 detects the vibration of the second filter plate 52. When the maximum vibration frequency of the second filter plate 52 decreases to a certain value, the vibration sensor 8 transmits an electrical signal to the control module. After receiving the electrical signal, the control module transmits the electrical signal to the suction pump 91, and the suction pump 91 starts.

[0060] After the suction pump 91 is started, the suction pump 91 sucks the sludge on the first filter plate 51 and the second filter plate 52 into the suction pipe 92, and then outputs it to the transport pipe 93. The sludge in the transport pipe 93 is transported to the temporary storage chamber for temporary storage.

[0061] The operating principle of this application is as follows: When it is necessary to pump sludge from sewage, the sewage pump 32 is started, bringing the inlet end of the sludge pumping pipe 31 close to the sludge. The sewage pump 32 sends the sludge and sewage together through the conveying pipe 33 into the temporary storage tank 2 for temporary storage. After the sludge and water are discharged from the conveying pipe 33, they fall onto the chain conveyor belt 44. The chain conveyor belt 44 separates the sludge and water. The sludge remains on the chain conveyor belt 44, while the water falls into the liquid storage chamber. The motor 41 is started, and the motor 41 drives the second roller 43 to rotate. The second roller 43, through the cooperation of the chain and two sprockets, drives the first roller 42 to move synchronously. The first roller 42 and the second roller 43 together drive the chain conveyor belt 44 to move, and the chain conveyor belt transports the sludge to the transition chamber.

[0062] The sludge falls onto the first filter plate 51 and the second filter plate 52, which further filter the wastewater in the sludge. When the second roller 43 rotates, it drives the first sprocket 71 to rotate. The first sprocket 71 drives the second sprocket 72 and the third sprocket 73 to rotate via the synchronous chain 74. The second sprocket 72 and the third sprocket 73 drive the two rotating shafts 61 to rotate. The rotating shafts 61 drive the fixed cylinder 62 connected to them to rotate along the axis of the rotating shafts 61. The fixed cylinder 62 drives the moving rod 63 to rotate. At this time, the spring 64 is stretched, and the moving rod 63 drives the striking block 66 to rotate. Under the action of the spring 64 and the force, the striking block 66 strikes the first filter plate 51 or the second filter plate 52, reducing the possibility of clogging the first filter plate 51 or the second filter plate 52.

[0063] As the shaft 61 continues to rotate, the spring 64 slowly contracts, and the striking block 66 slides against the first filter plate 51 or the second filter plate 52. The striking block 66 then disengages from the first filter plate 51 or the second filter plate 52, and the spring 64 is stretched again.

[0064] When the striking block 66 detaches from the first filter plate 51 or the second filter plate 52, if the amount of sludge stored in the transition chamber is large, the vibration frequency of the second filter plate 52 will be low. When the maximum vibration frequency of the second filter plate 52 decreases to a certain value, the vibration sensor 8 will transmit an electrical signal to the control module. After receiving the electrical signal, the control module will transmit the electrical signal to the suction pump 91, which will then start. The suction pump 91 will suck the sludge from the first filter plate 51 and the second filter plate 52 into the suction pipe 92, and then output it to the transport pipe 93, so that the sludge in the transport pipe 93 can be transported to the temporary storage chamber for temporary storage.

[0065] Once the temporary storage tank 2 is full, open the valves on the liquid outlet pipe 24 and the sludge outlet pipe 25 to drain the wastewater from the transition chamber and the storage chamber, and to drain the sludge from the temporary storage chamber. After both the wastewater and sludge have been drained, close the valves to facilitate further sludge removal.

[0066] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
