Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a multi-mechanism coordinated sedimentation tank scum removal and anti-clogging device. Background Technology

[0002] In wastewater treatment processes, sedimentation tanks are crucial for solid-liquid separation. Their surfaces often accumulate large amounts of scum, including grease, fibers, algae, and suspended particles. If this scum is not removed promptly, it can obstruct sunlight penetration, affect effluent quality, and even clog subsequent filtration units, increasing the treatment load. Existing scum removal equipment typically uses scrapers or rotary brushes to push the scum to a collection trough, from which it is then discharged via screw conveyor or pump. However, the following problems exist in actual operation:

[0003] In reality, scum often contains long, thin impurities such as fibers and flocs, which can easily bridge or entangle in the conical section of the scum collection bin and the horizontal conveying pipe, causing blockages. Furthermore, the scum has a high moisture content, and direct conveying increases the burden on subsequent dewatering. Moreover, existing equipment lacks an effective pressing and dewatering mechanism, and the scum still contains a large amount of water after simple filtration, resulting in high transportation costs and easy spoilage. In addition, the gap between the pressure rollers cannot be adjusted, making it difficult to adapt to scum with different properties. Therefore, the present application solves the shortcomings of the above-mentioned technical problems. Summary of the Invention

[0004] Based on the aforementioned technical problems, this invention proposes a multi-mechanism collaborative sedimentation tank scum removal and anti-clogging device.

[0005] This invention proposes a multi-mechanism collaborative sedimentation tank scum removal and anti-clogging device, comprising a floating vessel on the water surface of the sedimentation tank, wherein symmetrically distributed inclined support side plates are fixedly connected to the inner surface of the vessel's hull, the bottom ends of the support side plates extend to the water surface, and extension plates are fixedly connected to the upper surface of one end and one side surface of the lower end of the floating vessel, respectively. Scum scraping mechanisms are provided on the surfaces of the support side plates and the extension plates, and a conveying mechanism located on the floating vessel is provided below the material discharge end of the scum scraping mechanism. A pressing and dewatering mechanism is provided on the edge of the sedimentation tank via a support frame.

[0006] The scum scraping mechanism collects the scum in the sedimentation tank and pushes it into the conveying mechanism.

[0007] The conveying mechanism horizontally pushes the scum and then lifts it from the pool side to the inlet of the pressing and dewatering mechanism.

[0008] The pressing and dehydration mechanism grabs the scum and extracts the residual moisture from the scum through rotational extrusion.

[0009] Preferably, the slag scraping mechanism includes a scraper belt hinged together from multiple 304 stainless steel connecting strips. The scraper belt is disposed between the two supporting side plates and is driven by a drive shaft at its upper and lower ends. The floating vessel is equipped with a chain drive system. The chain drive system includes a reduction motor and a transmission gear housing, which are protected by a protective shell and installed inside the floating vessel. A transmission chain and a transmission sprocket, which are driven by another protective shell, are mounted on the outer surface of the drive shaft of the transmission gear housing. Another transmission sprocket is fixedly sleeved on the outer surface of one end of the upper drive shaft so that it drives the transmission chain.

[0010] In order to achieve continuous and stable scraping of scum on the surface of the sedimentation tank through the above technical solution, a scraper belt made of 304 stainless steel connecting strips and the supporting side plate form a stable scraping channel. At the same time, the upper transmission shaft is driven by the geared motor, transmission chain and sprocket inside the floating vessel, which drives the scraper belt to circulate. This allows the scraper belt to continuously scrape the scum from the water surface and push it to the next station. The protective shell seals and protects the transmission components to prevent impurities from entering and improve the reliability of the transmission.

[0011] Preferably, the slag scraping mechanism further includes a rubber scraping lip fixedly connected to the upper surface of the scraper belt connecting section, a rotating shaft rotatably connected to the surface of the extension plate via a bearing, an arc-shaped collecting plate fixedly connected to the outer surface of the rotating shaft in a ring shape, a driving bevel gear fixedly connected to the upper outer surface of the two drive shafts, a protective cover fixedly connected to the upper surface of the upper extension plate, a linkage shaft inserted through the surface of the protective cover via a bearing, driven bevel gears fixedly sleeved at both ends of the linkage shaft, and the driving bevel gear meshing with the corresponding driven bevel gear.

[0012] In order to improve the scraping efficiency of the scraper belt and prevent the scum from slipping off the edge of the scraper belt, the above technical solution is used to fix a rubber scraper lip on the upper surface of the scraper belt connecting section, so that a flexible seal is formed between the scraper belt and the water surface and the supporting side plate, which enhances the scum scraping effect. At the same time, in order to transmit the power of the scraper belt drive shaft to the collection plate synchronously, the meshing transmission of the active bevel gear and the driven bevel gear drives the linkage shaft to rotate, which in turn drives the rotating shaft and the arc-shaped collection plate to rotate, so that the collection plate can actively gather the scum on both sides of the scraper belt towards the center, reducing the scum residue.

[0013] Preferably, the upper surface of one of the extension plates is rotatably connected to a support shaft via a support ear plate, and a first linkage sprocket is fixedly sleeved on one end of the linkage shaft and the outer surface of one end of the support shaft, respectively. A first linkage chain is drivenly connected to the outer surfaces of the two first linkage sprockets, and a second linkage sprocket is fixedly sleeved on the outer surface of the support shaft and the outer surface of the drive shaft of the transmission gear housing, respectively. A second linkage chain is drivenly connected to the outer surfaces of the two second linkage sprockets.

[0014] Through the above technical solution, in order to transmit the driving force of the transmission gear housing to the scraper belt and the collecting plate via the linkage shaft, and to realize the synchronous linkage between the moving parts of the slag scraping mechanism, the power of the linkage shaft is transmitted to the support shaft through the first linkage sprocket and the first linkage chain, and then the power of the support shaft is transmitted to the drive shaft of the transmission gear housing through the second linkage sprocket and the second linkage chain, forming a closed-loop transmission link, so that the scraper belt and the collecting plate maintain coordinated operation.

[0015] Preferably, the conveying mechanism includes a slag collection bin located below the output end of the scraper belt. A horizontal conveying pipe is fixedly inserted into the lower surface of the slag collection bin. A roller shaft is rotatably connected to the inner surface of the lower end of the conical section of the slag collection bin. Plow blades are fixedly sleeved on the outer surface of the roller shaft in a staggered arrangement. A horizontal spiral conveying rod is rotatably connected to the inner surface of the horizontal conveying pipe via a bearing. A through-hole is provided on the upper surface of the horizontal conveying pipe. The plow blades are located above the horizontal spiral conveying rod. A linkage housing is installed on the outer surface of one end of the horizontal spiral conveying rod and the roller shaft. A rotating motor is fixedly connected to one side surface of the linkage housing. The linkage housing consists of a pulley that sleeves the outer surface of one end of the horizontal spiral conveying rod and the roller shaft, and a transmission belt. A lifting plate is fixedly connected to the inner top surface of the output end of the horizontal conveying pipe. The free end surface of the horizontal spiral conveying rod is rotatably connected to the surface of the lifting plate via a bearing.

[0016] In order to smoothly guide the scum collected by the scum scraping mechanism into the horizontal conveying pipe and prevent blockage in the conical section of the scum collection bin, the scum collected by the scraper belt is received by the scum collection bin. A roller with plow blades is set at the lower end of the conical section. The plow blades are randomly distributed and rotated by a rotating motor driven by the linkage housing to pre-crush and push the scum, so that it falls smoothly into the horizontal conveying pipe. At the same time, the horizontal spiral conveying rod rotates under the drive of the rotating motor, pushing the scum forward along the horizontal conveying pipe. The through-hole allows the scum to fall into the spiral rod conveying area.

[0017] Preferably, the conveying mechanism further includes a lifting pipe fixedly connected to the output end of the horizontal conveying pipe, a drainage hole is provided through the bottom surface of the lifting pipe, and a slag discharge pipe is fixedly connected to the lower surface of the output end of the lifting pipe.

[0018] Through the above technical solution, in order to lift the scum sent from the horizontal conveying pipe to the pressing and dewatering mechanism, and to initially discharge the free water carried in the scum before lifting to reduce the subsequent dewatering load, the output end of the horizontal conveying pipe is connected to the lifting pipe. The drainage hole at the bottom of the lifting pipe allows some water in the scum to flow out naturally before entering the lifting section, reducing the water content. The lifted scum enters the pressing and dewatering mechanism through the scum discharge pipe to achieve preliminary separation of scum and water.

[0019] Preferably, the inner surface of the lifting pipe is rotatably connected to a variable pitch helical blade via a bearing, the upper surface of the lifting pipe is fixedly connected to a lifting motor, the output shaft surface of the lifting motor is fixedly connected to the surface of the variable pitch helical blade via a coupling, the pitch of the inlet section of the variable pitch helical blade is smaller than the pitch of the middle and rear sections, and a truss erected on the side of the sedimentation tank is fixedly installed on the outer surface of the middle end of the lifting pipe.

[0020] Through the above technical solution, in order to smoothly lift the scum from the low water level to the inlet of the high-level pressing and dewatering mechanism and avoid blockage due to scum accumulation during the lifting process, a variable pitch spiral blade is rotated under the drive of the lifting motor. The pitch of the inlet section is small, which is convenient for grabbing and compressing the scum. The pitch of the middle and rear sections increases, which is conducive to the upward conveying of scum and reduces backflow. The truss supports the lifting pipe on the side of the sedimentation tank to ensure the stability of the equipment, while also making the drainage hole at the bottom of the lifting pipe function effectively.

[0021] Preferably, the pressing and dehydration mechanism further includes a pressing chamber mounted on the support frame. The pressing chamber is composed of a conical chamber, a cylindrical chamber, and a rectangular chamber connected from top to bottom. The two sides of the cylindrical chamber are symmetrically distributed and fixedly connected to a connecting chamber. Stainless steel pressure rollers are provided on the inner surfaces of the cylindrical chamber and the connecting chambers. The outer surfaces of the stainless steel pressure rollers are linearly distributed and fixedly fitted with annular ribs.

[0022] In order to improve the dewatering efficiency of scum through multi-stage pressing using the above technical solution, a pressing chamber is formed by a conical chamber, a cylindrical chamber, and a rectangular chamber connected from top to bottom. The scum passes through each section in sequence under the action of gravity. The cylindrical chamber has symmetrically connected connecting chambers on both sides. Stainless steel pressure rollers are installed inside. The annular ribs on the surface of the stainless steel pressure rollers exert a squeezing and shearing effect on the scum when rotating, which breaks the water-encapsulating structure in the scum, promotes the separation of water from the scum and discharges it along the chamber wall, and realizes continuous pressing and dewatering.

[0023] Preferably, the pressing and dehydration mechanism further includes a support base plate symmetrically distributed and fixedly connected to the inner surfaces of the cylindrical silo and the communicating silo. A stepped surface is formed on the upper surface of one end of the support base plate, and a sliding groove is formed through the upper surface of the stepped surface. A T-shaped pad is slidably connected to the inner surface of the sliding groove. Mounting ear plates are fixedly connected to the upper surfaces of the support base plate and the pad, respectively. The two ends of the stainless steel pressure roller are rotatably connected to the surfaces of the mounting ear plates via bearings. Adjusting screws are rotatably connected to the surface of the stepped surface. A shielding housing is installed on the outer surface of the two adjusting screws. Another pulley and a transmission belt assembly are arranged inside the shielding housing. A synchronous motor is fixedly connected to the outer surface of the pressing chamber. The output shaft of the synchronous motor extends into the interior of the shielding housing and drives one of the adjusting screws to rotate. A rotating ear plate is fixedly connected to one side surface of the support base plate. A bidirectional worm gear is rotatably connected to the surface of the rotating ear plate. A worm wheel is fixedly sleeved on the outer surface of one end of the output shaft of the stainless steel pressure roller. The worm wheel meshes with the corresponding end surface of the bidirectional worm gear. A driven gear is fixedly sleeved on the outer surface of the connecting chamber at one end of the bidirectional worm gear. A drive motor is fixedly connected to the surface of the connecting chamber. A driving gear is fixedly connected to the outer surface of the output shaft of the drive motor. The driving gear meshes with the driven gear.

[0024] To achieve precise adjustment of the gap between the stainless steel pressure rollers and adapt to the pressing needs of scum with different moisture contents and particle sizes, while ensuring synchronous drive of the pressure rollers, a T-shaped pad is installed on the stepped surface and sliding groove of the support base plate. The pad can move along the sliding groove. The adjusting screw rotates under the drive of the synchronous motor, pushing the pad to move, thereby changing the gap between the pressure rollers. At the same time, the drive motor drives the driving gear, driven gear and bidirectional worm gear to rotate. The bidirectional worm gear meshes with the worm wheel at the end of each pressure roller, so that all pressure rollers rotate synchronously in opposite directions, achieving uniform extrusion of scum. The structure of the adjusting screw and pad can adjust the gap between the pressure rollers online without stopping the machine.

[0025] Preferably, a slag discharge bin is provided below the pressing bin and installed on the surface of the support frame. A spiral slag discharge rod is rotatably connected to the inner surface of the slag discharge bin. A separation hole is opened through the inner bottom surface of the slag discharge bin. A slag discharge pipe is fixedly connected to the lower surface of the output end of the slag discharge bin. A slag discharge motor is fixedly connected to the upper surface of the support frame. A pulley assembly is drivingly connected to the outer surface of one end of the spiral slag discharge rod of the slag discharge motor.

[0026] Through the above technical solution, in order to discharge and collect the dry residue after pressing and dehydration in a timely manner, and to further separate the residual water, the dry residue falling from the bottom of the pressing chamber is received by the slag bin. The separation holes on the bottom surface of the slag bin allow the residual water squeezed out to continue to flow out. The spiral slag discharge rod rotates under the drive of the slag discharge motor, pushing the dry residue towards the slag discharge pipe and discharging it, thereby realizing the separation of residue and water and automatic slag discharge, and avoiding the accumulation of dry residue in the bin and causing blockage.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. By setting up a scum scraping mechanism, a scraper belt made of 304 stainless steel connecting strips is hinged to form a stable scum scraping channel with the inclined support side plate. A rubber scraper lip is fixed on the upper surface of the scraper belt connecting section, so that a flexible seal is formed between the scraper belt and the water surface and the support side plate, which enhances the scum scraping effect and prevents the scum from slipping off the edge. At the same time, through the meshing transmission of the active bevel gear and the driven bevel gear, the power of the scraper belt drive shaft is synchronously transmitted to the arc-shaped collection plate, so that the collection plate actively gathers the scum on both sides towards the middle, reducing the scum residue.

[0029] 2. By setting up a conveying mechanism, a slag collection bin is set below the output end of the scraper belt, and a roller with randomly distributed plow blades is set at the lower end of the conical section of the slag collection bin to pre-crush and push the slag, preventing blockage. The horizontal screw conveyor rod is driven by a rotating motor to push the slag forward along the horizontal conveying pipe. At the same time, a drainage hole is opened at the bottom of the lifting pipe to allow the free water of the slag to be initially discharged before lifting, reducing the subsequent dewatering load. The lifting pipe uses variable pitch screw blades with a small pitch in the inlet section and a large pitch in the middle and rear sections, which facilitates the grabbing, compression and upward conveying of slag, reducing backflow, thereby achieving a smooth transition of slag from horizontal collection to vertical lifting, effectively preventing blockage and water accumulation during the conveying process.

[0030] 3. By setting up a pressing and dewatering mechanism, a stainless steel pressure roller with annular ribs is used. During rotation, it squeezes and shears the scum, destroying the water-encapsulating structure and promoting water separation. T-shaped pads are installed on the stepped surface and sliding groove of the support base plate. The adjusting screw drives the pads to move under the drive of the synchronous motor, precisely adjusting the gap between the pressure rollers to adapt to scum with different moisture contents and particle sizes. At the same time, the drive motor, drive gear, driven gear and bidirectional worm gear drive each pressure roller to rotate synchronously in opposite directions, achieving uniform compression of the scum. The pressed dry scum falls into the scum bin below and is pushed out by the spiral scum discharge rod. The separation holes on the bottom of the scum bin further separate the residual water, thus achieving the overall effect of efficient continuous dewatering, adjustable pressing force and automatic scum discharge to prevent clogging.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0050] Reference Figures 1-17A multi-mechanism collaborative sedimentation tank scum removal and anti-clogging device includes a floating boat 1 on the water surface of the sedimentation tank. The inner surface of the floating boat 1 is fixedly connected with symmetrically distributed inclined support side plates 11. The bottom end of the support side plates 11 extends to the water surface. An extension plate 12 is fixedly connected to the upper surface of one end and the lower side surface of the floating boat 1, respectively. A scum scraping mechanism 2 is provided on the surface of the support side plates 11 and the extension plate 12. A conveying mechanism 4 on the floating boat 1 is provided below the material discharge end of the scum scraping mechanism 2. A pressing and dewatering mechanism 6 is provided on the edge of the sedimentation tank through a support frame 13.

[0051] Among them, the scum scraping mechanism 2 collects the scum in the sedimentation tank and pushes the scum into the conveying mechanism 4.

[0052] To achieve continuous and stable scraping of scum from the sedimentation tank surface, the scraping mechanism 2 includes a scraper belt 21 hinged from multiple 304 stainless steel connecting strips. The scraper belt 21 is positioned between two supporting side plates 11, and its upper and lower ends are connected by a drive shaft 22. The floating vessel 1 is equipped with a chain drive system, which includes a reduction motor 23 and a transmission gear housing 24, both protected by a protective shell and installed inside the floating vessel 1. A transmission chain 25 and a transmission sprocket 26, connected by another protective shell, are mounted on the outer surface of the drive shaft of the transmission gear housing 24. One end of the upper drive shaft 22 is fixedly sleeved with another drive sprocket 26, which drives the drive chain 25. The scraper belt 21, which is hinged by 304 stainless steel connecting strips, forms a stable slag scraping channel with the support side plate 11. At the same time, the upper drive shaft 22 is driven by the geared motor 23, drive chain 25 and sprocket inside the floating vessel 1, which drives the scraper belt 21 to rotate in a cycle. The scraper belt 21 can continuously scrape the slag from the water surface and push it to the next station. The protective shell seals and protects the transmission components to prevent impurities from entering and improve the reliability of the transmission.

[0053] To improve the scraping efficiency of the scraper belt 21 and prevent scum from slipping off the edge of the scraper belt 21, the scraping mechanism 2 also includes a rubber scraper lip 27 fixedly connected to the upper surface of the connecting section of the scraper belt 21. A rotating shaft 28 is rotatably connected to the surface of the extension plate 12 via bearings. Arc-shaped collection plates 29 are fixedly connected to the outer surface of the rotating shaft 28 in a ring-shaped arrangement. By fixing the rubber scraper lip 27 to the upper surface of the connecting section of the scraper belt 21, a flexible seal is formed between the scraper belt 21 and the water surface and the supporting side plate 11, enhancing the scraping effect. Simultaneously, to synchronously transmit the power of the drive shaft 22 of the scraper belt 21 to the collection plate 29, The upper outer surfaces of the two drive shafts 22 are fixedly connected to the drive bevel gears 30, and the upper surface of the upper extension plate 12 is fixedly connected to the protective cover 31. The surface of the protective cover 31 is connected to the linkage shaft 32 through the bearing. The two ends of the linkage shaft 32 are fixedly sleeved with driven bevel gears 33. The drive bevel gear 30 meshes with the corresponding driven bevel gear 33. Through the meshing transmission of the drive bevel gear 30 and the driven bevel gear 33, the linkage shaft 32 is driven to rotate, which in turn drives the rotating shaft 28 and the arc-shaped collection plate 29 to rotate, so that the collection plate 29 can actively gather the scum on both sides of the scraper belt 21 towards the center, reducing the scum residue.

[0054] In order to transmit the driving force of the transmission gear housing 24 to the scraper belt 21 and the collecting plate 29 via the linkage shaft 32 and realize the synchronous linkage between the moving parts of the slag scraping mechanism 2, the upper surface of one of the extension plates 12 is rotatably connected to the support shaft 34 through the support ear plate. The outer surface of one end of the linkage shaft 32 and the outer surface of one end of the support shaft 34 are respectively fixedly sleeved with the first linkage sprocket 35. The outer surfaces of the two first linkage sprockets 35 are connected to the first linkage chain 36. The outer surface of the support shaft 34 and the outer surface of the drive shaft of the transmission gear housing 24 are respectively fixedly sleeved with the second linkage sprocket 37. The outer surfaces of the two second linkage sprockets 37 are connected to the second linkage chain 38. The power of the linkage shaft 32 is transmitted to the support shaft 34 through the first linkage sprocket 35 and the first linkage chain 36, and then the power of the support shaft 34 is transmitted to the drive shaft of the transmission gear housing 24 through the second linkage sprocket 37 and the second linkage chain 38, forming a closed-loop transmission link, so that the scraper belt 21 and the collecting plate 29 maintain coordinated operation.

[0055] By setting up a scum scraping mechanism 2, a stable scum scraping channel is formed by a scraper belt 21 hinged with 304 stainless steel connecting strips and an inclined support side plate 11. A rubber scraper lip 27 is fixed on the upper surface of the connecting section of the scraper belt 21, so that a flexible seal is formed between the scraper belt 21, the water surface and the support side plate 11, which enhances the scum scraping effect and prevents the scum from slipping off the edge. At the same time, through the meshing transmission of the active bevel gear 30 and the driven bevel gear 33, the power of the drive shaft 22 of the scraper belt 21 is synchronously transmitted to the arc-shaped collection plate 29, so that the collection plate 29 actively gathers the scum on both sides towards the middle, reducing the scum residue.

[0056] Among them, the conveying mechanism 4 pushes the scum horizontally and then lifts it from the side of the pool to the inlet of the pressing and dewatering mechanism 6.

[0057] To ensure the smooth flow of scum collected by the scraper mechanism 2 into the horizontal conveying pipe 42 and prevent blockage in the conical section of the scum collection bin 41, the conveying mechanism 4 includes a scum collection bin 41 located below the output end of the scraper belt 21. A horizontal conveying pipe 42 is fixedly inserted into the lower surface of the scum collection bin 41. A roller 43 is rotatably connected to the inner surface of the lower end of the conical section of the scum collection bin 41. Plow blades 44 are fixedly sleeved onto the outer surface of the roller 43 in a staggered arrangement. A horizontal spiral conveying rod 45 is rotatably connected to the inner surface of the horizontal conveying pipe 42 via bearings. A through-hole 46 is provided on the upper surface of the horizontal conveying pipe 42. The plow blades 44 are positioned above the horizontal spiral conveying rod 45. A linkage housing 47 is installed on the outer surface of one end of the horizontal spiral conveying rod 45 and the roller 43. A rotating... The motor 48 and the linkage housing 47 are composed of a pulley and a transmission belt that fits onto the outer surface of one end of the horizontal spiral conveying rod 45 and the roller 43. A lifting plate 49 is fixedly connected to the inner top surface of the output end of the horizontal conveying pipe 42. The free end surface of the horizontal spiral conveying rod 45 is rotatably connected to the surface of the lifting plate 49 through a bearing. The scum output by the scraper belt 21 is received through the scum collection bin 41. A roller 43 with plow blades 44 is set at the lower end of the conical section. The plow blades 44 are randomly distributed and rotate under the drive of the rotating motor 48 and the linkage housing 47 to pre-crush and push the scum, so that it falls smoothly into the horizontal conveying pipe 42. At the same time, the horizontal spiral conveying rod 45 rotates under the drive of the rotating motor 48, pushing the scum forward along the horizontal conveying pipe 42. The through-hole 46 allows the scum to fall into the spiral rod conveying area.

[0058] In order to lift the scum delivered by the horizontal conveying pipe 42 to the pressing and dewatering mechanism 6, and to initially discharge the free water carried in the scum before lifting to reduce the subsequent dewatering load, the conveying mechanism 4 also includes a lifting pipe 50 fixedly connected to the output end of the horizontal conveying pipe 42. A drain hole 51 is opened through the bottom surface of the lifting pipe 50, and a slag discharge pipe 52 is fixedly connected to the lower surface of the output end of the lifting pipe 50. The lifting pipe 50 is connected to the output end of the horizontal conveying pipe 42, and the drain hole 51 at the bottom end of the lifting pipe 50 allows some water in the scum to flow out naturally before entering the lifting section, reducing the water content. The lifted scum enters the pressing and dewatering mechanism 6 through the slag discharge pipe 52 to achieve preliminary separation of scum and water.

[0059] To smoothly lift scum from the low water level to the inlet of the high-level pressing and dewatering mechanism 6, and to prevent scum accumulation and blockage during the lifting process, a variable pitch spiral blade 53 is rotatably connected to the inner surface of the lifting pipe 50 via a bearing. A lifting motor 54 is fixedly connected to the upper surface of the lifting pipe 50. The output shaft surface of the lifting motor 54 is fixedly connected to the surface of the variable pitch spiral blade 53 via a coupling. The pitch of the variable pitch spiral blade 53 at the inlet section is smaller than that in the middle and rear sections. A truss 55, which is erected on the side of the sedimentation tank, is fixedly installed on the outer surface of the middle end of the lifting pipe 50. The variable pitch spiral blade 53 rotates under the drive of the lifting motor 54. The smaller pitch at the inlet section facilitates the grabbing and compression of scum, while the larger pitch in the middle and rear sections facilitates the upward transport of scum and reduces backflow. The truss 55 supports the lifting pipe 50 on the side of the sedimentation tank, ensuring the stability of the equipment, and at the same time, enabling the drainage hole 51 at the bottom of the lifting pipe 50 to function effectively.

[0060] By setting up a conveying mechanism 4, a slag collection bin 41 is set below the output end of the scraper belt 21, and a roller 43 with randomly distributed plow blades 44 is set at the lower end of the conical section of the slag collection bin 41 to pre-crush and push the slag to prevent blockage. The horizontal spiral conveying rod 45 is driven by the rotating motor 48 to push the slag forward along the horizontal conveying pipe 42. At the same time, a drainage hole 51 is opened at the bottom of the lifting pipe 50 to allow the free water of the slag to be initially discharged before lifting, reducing the subsequent dewatering load. The lifting pipe 50 adopts variable pitch spiral blades 53 with a small pitch in the inlet section and a large pitch in the middle and rear sections, which facilitates the grabbing, compression and upward conveying of slag and reduces backflow, thereby realizing a smooth transition of slag from horizontal collection to vertical lifting, effectively preventing blockage and water accumulation during the conveying process.

[0061] The pressing and dehydration unit 6 grabs the scum and extracts the residual moisture from the scum through rotation and extrusion.

[0062] To improve dewatering efficiency through multi-stage pressing of scum, the pressing and dewatering mechanism 6 includes a pressing chamber 61 mounted on a support frame 13. The pressing chamber 61 consists of a conical chamber 611, a cylindrical chamber 612, and a rectangular chamber 613 connected from top to bottom. The two sides of the cylindrical chamber 612 are symmetrically distributed and fixedly connected to a connecting chamber 614. Stainless steel pressure rollers 62 are provided on the inner surfaces of the cylindrical chamber 612 and the connecting chamber 614. The outer surfaces of the stainless steel pressure rollers 62 are linearly distributed and fixedly fitted with rings. The annular ribs 63 form a pressing chamber 61, which is connected from top to bottom by a conical chamber 611, a cylindrical chamber 612, and a rectangular chamber 613. The scum passes through each section in sequence under the action of gravity. The cylindrical chamber 612 is symmetrically connected to the two sides by a connecting chamber 614. The inside is equipped with a stainless steel pressure roller 62. When the stainless steel pressure roller 62 rotates, the annular ribs 63 on the surface of the roller exert a squeezing and shearing effect on the scum, which breaks the water-encapsulating structure in the scum, promotes the separation of water from the scum and discharges it along the chamber wall, and realizes continuous pressing and dehydration.

[0063] To achieve precise adjustment of the gap between the stainless steel pressure rollers 62 to adapt to the pressing requirements of scum with different moisture contents and particle sizes, and to ensure synchronous drive of the pressure rollers, the pressing and dewatering mechanism 6 also includes a support base plate 64 symmetrically distributed and fixedly connected to the inner surfaces of the cylindrical silo 612 and the connecting silo 614. A stepped surface 65 is formed on the upper surface of one end of the support base plate 64, and a sliding groove 66 is formed through the upper surface of the stepped surface 65. A T-shaped pad 67 is slidably connected to the inner surface of the sliding groove 66. The upper surfaces of the support base plate 64 and the pad 67 are respectively fixedly connected... The stainless steel pressure roller 62 is connected to the mounting ear plate 68. The two end roller shafts 43 of the roller 62 are rotatably connected to the surface of the mounting ear plate 68 via bearings. Adjusting screws 69 are rotatably connected to the surface of the stepped surface 65. A shielding housing 70 is mounted on the outer surface of the two adjusting screws 69. Another pulley and a transmission belt assembly are installed inside the shielding housing 70. A synchronous motor 71 is fixedly connected to the outer surface of the pressing chamber 61. The output shaft of the synchronous motor 71 extends into the interior of the shielding housing 70 and drives one of the adjusting screws 69 to rotate. One side surface of the supporting base plate 64 is fixed. A rotating ear plate 72 is connected, and a bidirectional worm gear 73 is rotatably connected to the surface of the rotating ear plate 72. A worm wheel 74 is fixedly sleeved on the outer surface of one end of the output shaft of the stainless steel pressure roller 62. The worm wheel 74 meshes with the corresponding end surface of the bidirectional worm gear 73. One end of the bidirectional worm gear 73 extends to the outer surface of the connecting chamber 614 and is fixedly sleeved with a driven gear 75. A drive motor 76 is fixedly connected to the surface of the connecting chamber 614. A drive gear 77 is fixedly connected to the outer surface of the output shaft of the drive motor 76. The drive gear 77 meshes with the driven gear 75, and the drive motor 77 is connected to the outer surface of the supporting base plate 64. A T-shaped pad 67 is installed on the stepped surface 65 and the sliding groove 66. The pad 67 can move along the sliding groove 66. The adjusting screw 69 rotates under the drive of the synchronous motor 71, pushing the pad 67 to move, thereby changing the gap between the pressure rollers. At the same time, the driving motor 76 drives the driving gear 77, the driven gear 75 and the bidirectional worm gear 73 to rotate. The bidirectional worm gear 73 meshes with the worm wheel 74 at the end of each pressure roller, so that all pressure rollers rotate synchronously in opposite directions, realizing uniform extrusion of scum. The structure of the adjusting screw 69 and the pad 67 can adjust the gap between the pressure rollers online without stopping the machine.

[0064] To promptly discharge and collect the dehydrated residue after pressing, and to further separate residual moisture, a slag bin 78 is installed below the pressing chamber 61, mounted on the surface of the support frame 13. A spiral slag discharge rod 80 is rotatably connected to the inner surface of the slag bin 78, and a separation hole 79 is provided through the inner bottom surface of the slag bin 78. A slag discharge pipe 81 is fixedly connected to the lower surface of the output end of the slag bin 78, and a slag discharge motor 82 is fixedly connected to the upper surface of the support frame 13. A pulley assembly 83 is drivenly connected to one end of the spiral slag discharge rod 80. The slag bin 78 receives the dry residue falling from the bottom of the pressing chamber 61, and the separation hole 79 on the inner bottom surface of the slag bin 78 allows the squeezed residual moisture to continue to flow out. The spiral slag discharge rod 80 rotates under the drive of the slag discharge motor 82, pushing the dry residue towards the slag discharge pipe 81 and discharging it, thus achieving slag-water separation and automatic slag discharge, and preventing the dry residue from accumulating in the chamber and causing blockage.

[0065] By setting up a pressing and dewatering mechanism 6, a stainless steel pressure roller 62 with annular ribs 63 is used. When rotating, it squeezes and shears the scum, destroying the water-encapsulating structure and promoting water separation. A T-shaped pad 67 is installed on the stepped surface 65 and sliding groove 66 on the support base plate 64. The adjusting screw 69 drives the pad 67 to move under the drive of the synchronous motor 71, precisely adjusting the gap between the pressure rollers to adapt to scum with different moisture contents and particle sizes. At the same time, the driving motor 76, the driving gear 77, the driven gear 75 and the bidirectional worm gear 73 drive each pressure roller to rotate synchronously in opposite directions, realizing uniform squeezing of the scum. The pressed dry scum falls into the scum bin 78 below and is pushed out by the spiral scum discharge rod 80. The separation hole 79 on the bottom surface of the scum bin 78 further separates the residual water, thus achieving the overall effect of efficient continuous dewatering, adjustable pressing force and automatic scum discharge to prevent clogging.

[0066] Working Principle: In a specific embodiment, the working principle of this application is summarized, including the linkage between structures. Specifically, the reduction motor 23 inside the floating hull 1 drives the upper transmission shaft 22 via a transmission chain 25 and sprocket. This drives a scraper belt 21, made of 304 stainless steel connecting strips, to circulate between two inclined support side plates 11. The rubber scraper lip 27 on the upper surface of the scraper belt 21 scrapes scum from the water surface and pushes it upwards. Simultaneously, the transmission shaft 22, through the active bevel gear 30 and the driven bevel gear 30... The meshing of gear 33 drives the linkage shaft 32 to rotate. The linkage shaft 32 feeds power back to the drive shaft of the transmission gear housing 24 via the first linkage sprocket 35, the first linkage chain 36, the support shaft 34, the second linkage sprocket 37, and the second linkage chain 38, forming a closed-loop transmission link. This makes the scraper belt 21 and the arc-shaped collection plate 29 operate synchronously. The collection plate 29 rotates under the drive of the rotating shaft 28, gathering the scum on both sides of the scraper belt 21 towards the center, and finally pushing the scum into the scum collection bin 41 below the output end of the scraper belt 21.

[0067] After the slag collection bin 41 receives the slag, the roller 43 at the lower end of its conical section rotates under the drive of the rotating motor 48. The plow blades 44 randomly distributed on the surface of the roller 43 pre-crush and push the slag to prevent blockage. The crushed slag falls into the horizontal conveying pipe 42 through the through-hole 46. The horizontal spiral conveying rod 45 pushes the slag forward along the horizontal conveying pipe 42 under the drive of the rotating motor 48. When the slag enters the lifting pipe 50, the drain hole 51 at the bottom of the lifting pipe 50 initially discharges free water to reduce the subsequent dewatering load. The lifting motor 54 drives the variable pitch spiral blades 53 to rotate. The small pitch in the inlet section is convenient for grabbing and compressing the slag, while the large pitch in the middle and rear sections is conducive to upward conveying and reducing backflow. The slag is lifted from the low water level to the high level and sent into the inlet of the pressing bin 61 of the pressing and dewatering mechanism 6 through the slag discharge pipe 52.

[0068] After the scum enters the pressing chamber 61, it passes through the conical chamber 611, the cylindrical chamber 612, and the rectangular chamber 613 in sequence, falling under the action of gravity. The stainless steel pressure rollers 62 connected to the two sides of the cylindrical chamber 612 in the chamber 614 rotate under the drive of the drive motor 76. The drive motor 76 drives the bidirectional worm gear 73 to rotate through the drive gear 77 and the driven gear 75. The bidirectional worm gear 73 meshes with the worm wheel 74 at the end of each stainless steel pressure roller 62, so that all stainless steel pressure rollers 62 rotate synchronously in opposite directions. The annular ribs 63 on the surface of the stainless steel pressure rollers 62 exert a squeezing and shearing effect on the scum, destroying the water-encapsulating structure, promoting water separation and discharge along the chamber wall. The gap between the stainless steel pressure rollers 62 can be adjusted online by the synchronous motor 71 driving the adjusting screw 69 to rotate, pushing the T-shaped pad 67 to move along the sliding groove 66, thereby adapting to scum with different moisture contents and particle sizes.

[0069] The dehydrated slag falls into the lower slag bin 78. The separation hole 79 on the bottom surface of the slag bin 78 allows the residual water to continue to flow out. The spiral slag discharge rod 80 rotates under the drive of the slag discharge motor 82, pushing the dry slag towards the slag discharge pipe 81 and discharging it, thus completing the entire process of slag retrieval, transportation, dehydration and slag discharge.
