Description

Technical Field

[0001] This utility model belongs to the field of sludge dewatering, and in particular relates to a multi-station fully automatic vertical sludge dewatering equipment. Background Technology

[0002] Sludge filter presses are mainly used for sludge dewatering, effectively reducing sludge volume and significantly lowering transportation, storage, and subsequent treatment costs. They can even turn waste into valuable resources, such as filtering sludge into a mixed fuel with combustion value, thus generating economic benefits. Currently, the main type of sludge filter press on the market is the plate and frame filter press. The working principle of a plate and frame filter press is to use the compression of plates and frames to force water out of the sludge through the filter cloth, achieving dewatering. It mainly consists of recessed filter plates, a frame, an automatic-pneumatic closing system, a side plate suspension system, an air compressor, and a high-pressure filter cloth washing device. For automation, the filter plates are made of rigid, thick materials rather than flexible filter cloth, resulting in a large volume of filter plates and a large footprint for the equipment. Furthermore, because the side-pressurization method does not fully utilize the gravity of the sludge, the applied pressure is generally insufficient, leading to low filtration efficiency and a generally high moisture content in the filtered sludge, failing to fully achieve the goal of sludge volume reduction. Meanwhile, in order to achieve the effect of dewatering, plate and frame sludge filter presses usually add iron salts and lime as additives. That is, the sludge is increased first, and then the sludge dewatering work is carried out, which undoubtedly increases the cost of sludge filtration.

[0003] Application number CN202020146768.0 discloses a sludge dewatering device using a filter press. The sludge filter press includes a filter press barrel and a press. The filter press barrel is placed under the filter press platform of the press, and the press applies filtration pressure to the sludge inside the filter press barrel. The press includes a filter press cylinder, a filter press cylinder piston, a filter press platform, a filter press support, a filter press base, a filter barrel guide rail, and a filter press top seat. A filter press support is connected between the filter press top seat and the filter press base. A filter press cylinder is connected to the filter press top seat, and the piston of the filter press cylinder passes through the filter press top seat. The filter press platform is connected to the end of the filter press cylinder piston. A filter barrel guide rail is located on the filter press base, and the filter press barrel runs on the filter barrel guide rail. Its filtration process is concentrated in a single filter press station, lacking solutions for the winding and unwinding of the filter cloth and the transfer of sludge before and after filtration. The equipment mainly solves the filtration problem, and its function is relatively simple. Utility Model Content

[0047] like Figures 1 to 17 As shown in this embodiment, a multi-station fully automatic vertical sludge dewatering equipment includes a reciprocating sludge spreading device 2, a reciprocating cloth spreading device 3, a circulating conveyor line, a filter frame assembly 4, a hydraulic press 1, and a sludge unloading device 5. The filter frame assembly 4 flows along the circulating conveyor line and passes sequentially through the reciprocating cloth spreading device 3, the hydraulic press 1, and the sludge unloading device 5. The reciprocating sludge spreading device 2 is located on one side of the circulating conveyor line. The filter frame assembly 4 includes a frame body 41. The sludge spreading end of the reciprocating sludge spreading device 2, the cloth spreading end of the reciprocating cloth spreading device 3, the pressure head of the hydraulic press 1, and the sludge unloading end of the sludge unloading device 5 are all located above the frame body 41. Sludge enters the reciprocating sludge spreading device 2 and is spread into the frame body 41 by the reciprocating sludge spreading device 2. Combined with the reciprocating cloth spreading device folding and spreading back and forth, automatic material spreading is achieved, forming a cloth-sludge-cloth interlayer. The filter frame assembly 4, after being laid out, is conveyed to the hydraulic press 1 via a circulating conveyor line. The hydraulic press 1 then applies pressure to achieve the filtration process. After filtration, the filter frame assembly 4, now containing dry mud, is conveyed to the mud discharge device 5 via the same circulating conveyor line. The mud discharge device 5 separates the dry mud from the cloth, which can then be transported to a storage location via a belt conveyor or directly removed. This distribution of the filtration process across different workstations enables a streamlined operation of wet mud feeding, laying, filtration, and dry mud discharge. The workstations can be flexibly configured for efficiency, and additional waiting workstations can be added to ensure continuous operation of the core workstations, resulting in extremely high uptime. The circulating conveyor line facilitates the cyclical transport of the filter frame assembly 4, allowing it to move between workstations. Multiple filter frame assemblies 4 can be installed on the circulating conveyor line to increase output. Hydraulic press 1 performs filtration from top to bottom, making full use of the pressure of hydraulic press 1 and the gravity of the material. Compared with common methods on the market such as centrifuges, belt filter presses, and plate and frame horizontal filter presses, it has a shorter filtration time and lower sludge moisture content under the same conditions. It also has many advantages such as small footprint and short feeding time.

The screw pump 25 is fixedly connected to the moving end of the first X-axis linear motion assembly 27. The inlet end of the screw pump 25 is fixedly connected to the hose 24, and the inlet end of the hose 24 is fixedly connected to the outlet end of the hopper 23. The outlet end of the screw pump 25 is fixedly connected to the sludge spreading head 26, which has a flat sludge spreading opening 28 located above the frame 41. The hopper 23 can be connected to various sludge output ports of a wastewater treatment plant, allowing for plug-and-play operation regardless of the site, while ensuring timely supply of wet sludge and continuous operation of the equipment. The wet sludge enters the screw pump 25 through the hose 24 and is then transported to the sludge spreading head 26 by the screw pump 25. The wet sludge is spread on the flexible filter cloth 44 through the flat sludge spreading port 28. The flat sludge spreading port 28 is driven to move left and right by the first X-axis linear motion component 27. The combination of the flat sludge spreading port 28 and the first X-axis linear motion component 27 ensures the uniform spreading of the wet sludge.

A screw pump 25 is fixed to the top of the first mounting frame 273. The telescopic end of the first telescopic cylinder 274 is fixedly connected to the first mounting frame 273. The telescopic movement of the first telescopic cylinder 274 causes the first mounting frame 273 to move left and right, which in turn causes the screw pump 25 to move left and right, thereby causing the paving head 26 to move left and right for uniform paving operations.

Then, the Y-axis linear motion component 34 drives the roller 37 to move inward, causing the right roller 37 to extend into the inside of the flexible filter cloth 44. The second X-axis linear motion component 32 drives the left and right rollers 37 to approach and contact the flexible filter cloth 44.

At the same time, the second X-axis linear motion component 32 reciprocates left and right, driving the roller 37 to reciprocate left and right, thereby driving the flexible filter cloth 44 to be layered and laid, eliminating the need for manual laying and increasing efficiency.

[0051] The second X-axis linear motion assembly 32 includes a second guide rail 321, a second roller 322, a first rack 323, a first gear 324, and a first motor 325.

The telescopic ends of the two third telescopic cylinders 351 are fixedly connected to the two fourth mounting brackets 352 respectively. The roller 37 is rotatably connected to the fourth mounting bracket 352. The telescopic cylinders 341 extend and retract, causing the third mounting bracket 342 to move back and forth. The telescopic cylinders 351 extend and retract, causing the fourth mounting bracket 352 to move left and right, thus causing the roller 37 to move left and right.

[0053] The filter frame assembly 4 also includes a fifth mounting bracket 42, a cloth rolling roller 43, a flexible filter cloth 44, a handwheel 45, a guide roller 46, a pressing roller 47, a torsion spring shaft 48, a lifting platform 49, a connecting rod 410, a water collection frame 411, a support seat 412, and a lower mud plate 413.

Pressing roller 47 is hinged to fifth mounting bracket 42 through torsion spring shaft 48. Pressing roller 47 presses on flexible filter cloth 44. The flexible filter cloth 44 is automatically tensioned during winding and unwinding by the pressure roller 47 combined with the torsion spring shaft 48. Combined with the threaded section 415 on the guide roller 46, the flexible filter cloth 44 is spread out during unwinding to avoid wrinkles and achieve automatic correction. During the first layer of sludge laying, a flexible filter cloth 44 is placed on the top surface of the support base 412. The lifting platform 49 moves the support base 412 upward until the flexible filter cloth 44 on its top surface is flush with the top surface of the frame 41. At this point, the first layer of wet sludge is laid using the reciprocating sludge laying device 2. After the first layer is laid, the flexible filter cloth 44 is pulled to the left by the reciprocating cloth laying device 3 to cover the first layer of wet sludge. Then, the flexible filter cloth 44 is pulled to the right to lay the next layer of flexible filter cloth 44 for supporting the wet sludge. The lifting platform 49 descends a certain distance so that the top surface of the second layer of flexible filter cloth 44 is located at the top surface of the frame 41, and the second layer of wet sludge is laid. This process is repeated until the entire frame is covered. No manual material laying is required, resulting in higher efficiency. Water generated during the filter pressing process is discharged through the drain hole 414 to the water collection frame 411 for collection. The lower sludge plate 413 is installed to guide the unloading process. During unwinding, the first rotating component 38 drives the handwheel 45 to rotate, causing the fabric roll 43 to rotate for unwinding. In this embodiment, the first rotating component 38 is located on the front side of the fabric roll 43. In other embodiments, the first rotating component 38 can be located on both the front and rear sides of the fabric roll 43. By winding on both sides, the load is more balanced and the speed is greatly improved.

[0054] The circulating conveyor line includes several spaced conveyor modules 6. Each conveyor module 6 includes a rotating platform 61, a base 62, a second motor 63, a first transmission assembly 64, and conveyor wheels 65. The second motor 63 is fixed to the base 62. Several conveyor wheels 65 are rotatably connected to opposite sides of the top of the base 62. The conveyor wheels 65 are equidistantly distributed along the length of the base 62. The second motor 63 and the conveyor wheels 65 are connected by the first transmission assembly 64. The bottom of the base 62 between the reciprocating spreading device 3 and the hydraulic press 1, and between the hydraulic press 1 and the unloading device 5, is fixedly connected to the rotating end of the rotating platform 61. When the second motor 63 rotates, it drives the conveyor wheels 65 to rotate through the first transmission assembly 64, thus conveying the frame 41. By setting up each independently configured conveyor module 6, different numbers of conveyor modules 6 can be configured for conveying according to requirements. The rotating platform 61 can change the conveying direction, enabling linear and angular conveying, thereby achieving cross-station circulation and cyclic conveying of the filter frame assembly 4 to adapt to different operational needs. Adopting a multi-station production line layout that conforms to the modular design concept, the number of conveyor modules can be flexibly configured, some core stations can be reused, and the production line can increase capacity by adding other stations rather than adding the entire production line, depending on production efficiency requirements. This demonstrates extremely high scalability and a very high return on investment. After each station completes its work, the data flows to the next station or a waiting station. Stations can be flexibly configured according to efficiency, and waiting stations can be added to ensure continuous operation of core stations, thereby achieving extremely high utilization rates.

[0055] The sludge unloading device 5 includes a fourth frame 51, a sixth guide rail 52, a slider 53, a second rack 54, a second gear 55, a third motor 56, a seventh mounting bracket 57, a fifth telescopic cylinder 58, a seventh guide rail 59, a fourth open linear bearing 510, an eighth mounting bracket 511, a bearing seat 512, a second rotating component 513, a through rod 514, a roller brush 515, a second transmission assembly 516, and a fourth motor 517. The sixth guide rail 52 is fixed to the top of the fourth frame 51, and the slider 53 is slidably connected to the sixth guide rail 52. The seventh mounting bracket 57 is fixed to the top of the slider 53. The third motor 56 is fixed to the seventh mounting bracket 57, and the second gear 55 is fixed to the bottom of the third motor 56. The second gear 55 is connected to the fourth frame 51. Two racks 54 mesh. A fifth telescopic cylinder 58 and a seventh guide rail 59 are fixed to the front and rear sides of the bottom of the seventh mounting bracket 57. A fourth open linear bearing 510 is slidably connected to the seventh guide rail 59. An eighth mounting bracket 511 is fixed to the bottom of the fourth open linear bearing 510. The telescopic end of the fifth telescopic cylinder 58 is fixedly connected to the eighth mounting bracket 511. A bearing seat 512 is fixed to the eighth mounting bracket 511. The outer end of the through rod 514 is inserted into the bearing seat 512. A second rotating component 513 is fixed to the fourth frame 51. Two vertically distributed roller brushes 515 are rotatably connected to the fourth frame 51. A fourth motor 517 is fixed to the fourth frame 51 and is connected to the two roller brushes 515 via a second transmission assembly 516. Before unloading the sludge, the conveying module 6 between the lower sludge plate 413 and the filter press rotates the filter frame assembly 4 180 degrees, so that the lower sludge plate 413 faces right. After the material frame assembly is conveyed to the conveying module 6 at the sludge unloading device 5, the second rotating component 513 drives the cloth winding roller 43 to perform a winding operation. During the winding process, the dry mud falls off the flexible filter cloth 44 under the action of gravity and is discharged through the lower mud plate 413. The rotation of the third motor 56 drives the second gear 55 to rotate. Under the action of the second rack 54, the seventh mounting frame 57 moves to the left, driving the threading rod 514 to move to the left to the cloth winding roller 43. Then, the fifth telescopic cylinder 58 extends, driving the threading rod 514 to extend into the left side of the flexible filter cloth 44. The rotation of the third motor 56 in the opposite direction causes the threading rod 514 to move to the right, pushing the flexible filter cloth 44 to the right between the upper and lower roller brushes 515. The rotation of the fourth motor 517 drives the roller brushes 515 to rotate through the second transmission component 516. During the winding, the surface of the flexible filter cloth 44 is brushed with mud to remove the dry mud that has not fallen off naturally under the action of gravity. Thus, automatic mud unloading occurs during the winding process, ensuring clean mud removal and greatly improving efficiency. In this embodiment, each fourth frame 51 has two front-to-back sixth guide rails 52 fixed to its top, and the second rack 54 is fixed only to the inner side of the outer second guide rail 321. The second rotating component 513 is located on the rear side of the fabric winding roller 43; in other embodiments, the second rotating component 513 may be located on both the front and rear sides of the fabric winding roller 43.Both the first transmission component 64 and the second transmission component 516 are chain drives.

[0056] The first rotating component 38 and the second rotating component 513 both include a fifth guide rail 7, a fourth telescopic cylinder 8, a third open linear bearing 9, a sixth mounting bracket 10, a rotary cylinder 11, and an insert rod 12. The fifth guide rail 7 is slidably connected to the third open linear bearing 9, and the sixth mounting bracket 10 is fixed to the top of the third open linear bearing 9. The telescopic end of the fourth telescopic cylinder 8 is fixedly connected to the sixth mounting bracket 10, and the rotary cylinder 11 is fixed to the top of the sixth mounting bracket 10. The rotary end of the rotary cylinder 11 is fixed to the insert rod 12, which is positioned opposite to the handwheel 45. When the handwheel 45 needs to be rotated, the fourth telescopic cylinder 8 extends, causing the sixth mounting bracket 10 to move closer to the handwheel 45, which in turn causes the rotary cylinder 11 to move closer to the handwheel 45. This allows the insert rod 12 to be inserted into the handwheel 45. The rotary cylinder 11 then rotates the insert rod 12, which in turn rotates the handwheel 45, thus achieving automatic winding and unwinding.
