Description

Technical Field

[0001] This utility model belongs to the field of sludge treatment, specifically relating to a conveying system for a dewatering machine. Background Technology

[0002] The key to reducing sludge moisture content for volume reduction and resource utilization lies in the dewatering process. Traditional methods primarily rely on thermal drying technology. Conventional solutions using disc dryers consume 1.35-1.55 tons of steam per ton of water to reduce sludge moisture content from 80% to 40%, but the cost is 230 yuan per ton, facing constraints in both energy consumption and economics. Therefore, a mechanical pressure filtration dewatering process has been proposed, which rapidly reduces sludge moisture content from 80% to 60% through high-pressure pressing, effectively reducing the steam consumption for subsequent thermal drying.

[0003] Chinese utility model patent CN212152035U discloses a deep sludge dewatering device. It achieves automated filtration through a linear arrangement of the material feeding station, filter pressing station, and sludge washing station, offering advantages such as no need for chemical additives and stable operation. However, it also has the following drawbacks: 1. The linear layout of each module (station) results in a large footprint and poor site adaptability, limiting its placement to narrow working areas. 2. The filtration device requires external equipment such as a crane to transport it back to the starting point, increasing equipment investment costs and operating energy consumption. Utility Model Content

[0004] This utility model proposes a dehydrator conveying system, the purpose of which is to solve the problems of large land area required by existing conveying methods, as well as the high cost and low efficiency of transporting goods by cranes and other equipment.

[0005] The technical solution of this utility model is as follows:

[0006] A dewatering machine conveying system includes a base, on which a pre-compression station, a main compression station, an unpacking station, and a mud-coating station are arranged; the unpacking station, mud-coating station, pre-compression station, and main compression station are distributed at the four vertices of a rectangle to form a closed loop path;

[0007] The dewatering machine conveying system also includes containers for stacking mud bags, and second transverse tracks running left and right on the unpacking station, mud-packing station, pre-compression station, and main compression station; it also includes two sets of longitudinal tracks located on the left side of the pre-compression station and main compression station, and between the pre-compression station and main compression station and the mud-packing station and unpacking station; and it also includes two longitudinal transfer cars that move back and forth along the two sets of longitudinal tracks respectively.

[0008] The longitudinal transfer vehicle is equipped with a first transverse track that is at the same height as and matches the second transverse track, and when the two are aligned, they can be spliced ​​into a continuous track.

[0009] The container consists of two or more transverse transfer vehicles equipped with cage frames, and the wheels at the bottom of the transverse transfer vehicles are used to cooperate with the first transverse track and the second transverse track.

[0010] As a further improvement to the dewatering machine conveying system: the transverse transfer car has a window in the middle, and a lifting pallet for carrying mud bags is provided above the window; the lifting pallet is slidably engaged with the cage frame, and the area of ​​the lifting pallet is larger than the area of ​​the window;

[0011] The bottom of the unpacking station and the mud packing station are respectively equipped with a first lifting mechanism. The lifting push plate at the top of the first lifting mechanism is used to drive the lifting tray and the mud packs stacked above it to move up and down through the window.

[0012] As a further improvement to the dehydrator conveying system: multiple support springs are installed around the window of the transverse transfer vehicle through mounting holes, and the top of the support springs is used to contact the bottom of the lifting tray.

[0013] As a further improvement to the dehydrator conveying system: the first lifting mechanism includes two screw jacks arranged in parallel, and the upper ends of the screws driven by the two screw jacks are connected to the bottom of the lifting push plate.

[0014] As a further improvement to the dehydrator conveying system: the drive shafts of the two screw jacks are connected by an intermediate connecting shaft to achieve synchronous rotation, and one of the drive shafts is connected to a drive motor.

[0036] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Example 1

[0037] like Figures 1 to 4A dewatering machine conveying system includes a base 1, on which a pre-compression station 21, a main compression station 16, an unpacking station 18, and a mud-coating station 19 are arranged. The unpacking station 18, the mud-coating station 19, the pre-compression station 21, and the main compression station 16 are distributed at the four vertices of a rectangle and form a closed loop path in a clockwise (or counterclockwise) direction.

[0038] Pre-pressing station 21 and main pressing station 16 are respectively equipped with pre-pressing device 2 and main pressing device 3. They press down on the mud bag with oil cylinders to squeeze out the water in the mud bag and achieve filter dewatering.

[0039] Specifically, such as Figures 1 to 4 The pre-compression station 21 and the main compression station 16 are located to the left of the mud-packing station 19 and the unpacking station 18.

[0040] The dewatering machine conveying system also includes containers for stacking mud bags, and second transverse tracks 14 running left and right on the unpacking station 18, mud packing station 19, pre-compression station 21 and main compression station 16; it also includes two sets of longitudinal tracks 12 located to the left of the pre-compression station 21 and main compression station 16 and between the pre-compression station 21 and main compression station 16 and the mud packing station 19 and unpacking station 18; and two longitudinal transfer cars 10 that move back and forth along the two sets of longitudinal tracks 12 respectively.

[0041] The longitudinal transfer vehicle 10 is equipped with a first transverse track 13 that is at the same height as and matches the second transverse track 14. When the two are aligned, they can be spliced ​​into a continuous track.

[0042] like Figure 5 The container consists of four transverse transfer vehicles 11 equipped with cage frames, and the wheels at the bottom of the transverse transfer vehicles 11 cooperate with the first transverse track 13 and the second transverse track 14.

[0043] The longitudinal transfer vehicle 10 and the transverse transfer vehicle 11 are equipped with their own drive devices (motors) and travel along the corresponding tracks by means of wheels.

[0044] Furthermore, such as Figures 5 to 7 The transverse transfer vehicle 11 has a window in the middle, and a lifting pallet 23 for carrying mud bags is provided above the window. The lifting pallet 23 is slidably engaged with the cage frame, and the area of ​​the lifting pallet 23 is larger than the area of ​​the window.

[0045] Furthermore, multiple support springs 24 are installed around the window of the transverse transfer carriage 11 through mounting holes. The top of the support springs 24 is used to contact the bottom of the lifting pallet 23 to provide a cushioning effect. However, during filter pressing and dewatering, the bottom of the lifting pallet 23 will directly contact the transverse transfer carriage 11 and be supported by the transverse transfer carriage 11.

[0046] Correspondingly, the bottom of the unpacking station 18 and the mud packing station 19 are respectively equipped with a first lifting mechanism 9. The lifting push plate 26 at the top of the first lifting mechanism 9 is used to pass through the window to drive the lifting tray 23 and the mud packs stacked above it to move up and down.

[0047] Specifically, such as Figure 8 The first lifting mechanism 9 includes two parallel screw jacks 25, the upper ends of the screws driven by both screw jacks 25 being connected to the bottom of the lifting push plate 26. The drive shafts of the two screw jacks 25 are connected by an intermediate connecting shaft to achieve synchronous rotation, and one of the drive shafts is connected to a drive motor. The bottom of the screw jacks 25 has a deep hole structure to provide sufficient movement space for the screws. Example 2

[0048] This embodiment provides a dehydrator based on the conveying system of Embodiment 1.

[0049] like Figure 1 , Figure 3 and Figure 9 The unpacking station 18 is equipped with an unpacking device 4, which is used to open the mud bags in the container. The substrate 1 is also equipped with a filter cloth transfer cart 5 and a filter cloth cleaning device 6 located between the unpacking station 18 and the mud-packing station 19. The filter cloth transfer cart 5 is used to transport the unpacked filter cloth to the mud-packing station 19, and the filter cloth cleaning device 6 is used to clean the sludge from the unpacked filter cloth. The mud-packing station 19 is equipped with a mud-laying device 7 and a mud-packing device 8. The mud-laying device 7 is used to lay the sludge to be dewatered onto the filter cloth, and the mud-packing device 8 is used to pack the sludge into a container using the filter cloth.

[0050] Specifically, such as Figure 3 , Figure 4 , Figure 9 and Figure 12 The unpacking device 4 includes a first frame 40 fixedly disposed above the unpacking station 18 and relative to the base 1. The first frame 40 has a rectangular first opening for the mud bag to pass through. A set of cloth lifting mechanisms are respectively provided on the rear side of the first opening, i.e. the side away from the mud packing station 19, and on the left and right sides of the first opening.

[0051] like Figure 12 and Figure 13The fabric lifting mechanism includes a first movable frame 39 and a first rotating plate 37. The first movable frame 39 is horizontally slidably connected to the first frame 40 and moves away from and towards the first opening under the drive of the first moving drive device 41. The outer end of the first rotating plate 37, i.e., the end away from the first opening, is rotatably connected to the first movable frame 39, and the inner end of the first rotating plate 37 is equipped with multiple magnetic suction devices 38 for adsorbing iron blocks at the edge of the filter cloth. The first movable frame 39 is also provided with a lifting mechanism 42 for pushing the first rotating plate 37 to rotate.

[0052] In this embodiment, the first moving drive device 41 is a cylinder.

[0053] In this embodiment, the lifting mechanism 42 is a cylinder, the lower end of which is rotatably connected to the first movable frame 39 and the upper end of which is rotatably connected to the first rotating plate 37.

[0054] like Figure 11 A frame 31 is installed on the base 1, spanning the unpacking station 18 and the mud-packing station 19.

[0055] The filter cloth cleaning device 6 is located in the middle of the frame 31. It includes a third lifting mechanism 32, a roller 33, a mud plate 34, and a collection trough 35.

[0056] The roller 33, sludge dewatering plate 34, and collection trough 35 are arranged sequentially from top to bottom. The roller 33 moves up and down relative to the frame 31 under the drive of the third lifting mechanism 32, while the sludge dewatering plate 34 and collection trough 35 are fixedly set relative to the frame 31.

[0057] The frame 31 is also equipped with a transfer track 36. The filter cloth transfer cart 5 travels back and forth along the transfer track 36 between the unpacking station 18 and the mud-wrapping station 19, passing through the gap between the roller 33 and the mud-dampening plate 34 during its movement. Figure 14 The filter cloth transfer vehicle 5 is equipped with a gripper 43 for gripping the filter cloth.

[0058] like Figure 9 , Figure 10 and Figure 16 The mud-spreading device 7 is mounted on the frame 31 via a second lifting mechanism 27 and is located directly above the mud-coating station 19. A guide column 30 is also connected to the mud-spreading device 7, and the guide column 30 cooperates with a guide sleeve on the frame 31.

[0059] The sludge distribution device 7 has a sludge trough 28 whose shape matches that of the sludge bag, and a pipe for conveying sludge is provided above the sludge trough 28. Two sliding, opposing gates 29 are provided at the bottom of the sludge trough 28. Specifically, a motor and a transmission chain mechanism are respectively provided on both sides of the sludge trough 28 of the sludge distribution device 7. The motor drives the transmission chain mechanism to operate, and the chain of the transmission chain mechanism is connected to the gate 29 on the corresponding side, controlling the gate 29 to move horizontally along the slide rail at the bottom of the sludge distribution device 7.

[0060] like Figure 9 , Figure 17 and Figure 18 The mud-wrapping device 8 includes a second frame 45 fixedly disposed above the mud-wrapping station 19 and relative to the base 1. The second frame 45 has a rectangular second opening for the mud bag to pass through. A set of covering mechanisms are respectively disposed around the second opening.

[0061] The cover mechanism includes a second movable frame 46 and a second rotating plate 44. The second movable frame 46 is horizontally slidably connected to the second frame 45 and moves away from and towards the second opening under the drive of the second moving drive device 47. The root of the second rotating plate 44 is rotatably connected to the second movable frame 46.

[0062] The cover mechanism also includes a rotary drive device 48, a swing arm 49, and a connecting rod 50. The rotary drive device 48 (which can be a rotary cylinder or a motor) is mounted on the second frame 45 and is used to drive the swing arm 49 to swing. One end of the connecting rod 50 is rotatably connected to the swing arm 49, and the other end is rotatably connected to the second rotating plate 44.

[0063] In this embodiment, the second moving drive device 47 consists of two sets of cylinders.

[0064] In this embodiment, the connecting rod 50 includes two threaded rods with opposite thread directions and a threaded sleeve. The two ends of the threaded sleeve are threadedly engaged with the two threaded rods respectively. Rotating the threaded sleeve can adjust the length of the entire connecting rod 50, thereby changing the angular travel of the second rotating plate 44.

[0065] The aforementioned dehydrator alternately performs the transfer phase actions and the working phase actions during operation:

[0066] During the transfer phase, the four cages on the unpacking station 18, the mud packing station 19, the pre-compression station 21, and the main compression station 16 are moved to the next station along a closed-loop path using a conveying system.

[0067] Before the transfer phase begins, all first lifting mechanisms 9 must be lowered to their lowest positions to avoid interference.

[0068] Specifically, such as Figure 3The process of the transfer phase is as follows:

[0069] Step 1: The two longitudinal transfer cars 10 are moved to the left and right sides of the pre-compression station 21, namely the second transfer station 22 and the fourth transfer station 20.

[0070] Step 2: The transverse transfer car 11 on the pre-compression station 21 moves to the left onto the longitudinal transfer car 10 on the left side (second transfer station 22). Then, the transverse transfer car 11 on the mud-coating station 19 moves to the left, passing through the longitudinal transfer car 10 between the pre-compression station 21 and the mud-coating station 19 (fourth transfer station 20) to reach the pre-compression station 21.

[0071] Step 3: The two longitudinal transfer cars 10 are moved to the left and right sides of the main pressing station 16, namely the first transfer station 15 and the third transfer station 17.

[0072] Step 4: The transverse transfer car 11 on the unpacking station 18 moves to the left and arrives at the longitudinal transfer car 10 located between the main pressing station 16 and the unpacking station 18 (the third transfer station 17).

[0073] Step 5: The longitudinal transfer car 10, located between the main pressing station 16 and the unpacking station 18 (third transfer station 17), moves to the pre-pressing station 21 and the mud-packing station 19 (fourth transfer station 20).

[0074] Step 6: The transverse transfer car 11 on the longitudinal transfer car 10 between the pre-compression station 21 and the mud-coating station 19 (fourth transfer station 20) moves to the right onto the mud-coating station 19.

[0075] Step 7: The longitudinal transfer car 10 between the pre-compression station 21 and the mud-packing station 19 (fourth transfer station 20) moves to the main compression station 16 and the unpacking station 18 (third transfer station 17).

[0076] Step 8: The transverse transfer car 11 on the main pressing station 16 moves to the unpacking station 18 via the longitudinal transfer car 10 located between the main pressing station 16 and the unpacking station 18 (third transfer station 17). Then, the transverse transfer car 11 on the longitudinal transfer car 10 on the left side of the main pressing station 16 (first transfer station 15) moves to the right onto the main pressing station 16.

[0077] At this point, the containers (cages) at the four workstations have each moved one workstation clockwise.

[0078] During the working phase, the pre-compression device 2 and the main compression device 3 press and filter the mud bags in the cages at their respective workstations to remove water. The unpacking device 4 unpacks the mud bags in the cages at its respective workstations one by one. The filter cloth transfer cart 5 moves back and forth between the unpacking workstation 18 and the mud-packing workstation 19, moving the removed filter cloths one by one to the mud-packing device 8, and cleaning the filter cloths using the filter cloth cleaning device 6 during the movement. The mud-laying device 7 lays the sludge on the transferred filter cloth. The mud-packing device 8 packages the filter cloth and the laid sludge into mud bags and puts them into the cages at its workstation.

[0079] The specific actions during the work phase are as follows:

[0080] Pre-compression device 2 and main compression device 3 dewater the mud bags at their respective workstations by pressing and filtering them. At the same time:

[0081] The first lifting mechanism 9 of the unpacking station 18 operates intermittently, advancing the mud bags one by one according to the thickness of the mud bag, pushing the mud bags in the cage of the unpacking station 18 into the first opening of the unpacking device 4. Meanwhile, the first lifting mechanism 9 of the mud-packing station 19 operates intermittently, advancing the mud bags one by one according to the thickness of the mud bag, causing the mud bags packaged by the mud-packing device 8 to fall into and be stacked in the cage of the mud-packing station 19.

[0082] Whenever a new mud bag appears above the first opening of the unpacking device 4, the three cloth-lifting mechanisms of the unpacking device 4 perform the following actions in sequence according to the covering order of the filter cloth: the first moving frame 39 of the corresponding cloth-lifting mechanism moves horizontally closer to the mud bag, and uses the magnetic suction device 38 at the inner end of the first rotating plate 37 on the first moving frame 39 to attract the iron block on the filter cloth. Then the first rotating plate 37 is raised, pulling up the edge of the filter cloth on that side. After that, the first moving frame 39 moves outward, lifting the edge of the filter cloth on that side until the iron block on the filter cloth is removed from the magnetic suction device 38. Then the first rotating plate 37 falls back into place. After the three cloth-lifting mechanisms complete the unpacking, only the edge of the filter cloth near the mud-packing station 19 is covered with sludge.

[0083] Then the filter cloth transfer cart 5 grasps the edge of the opened filter cloth away from the mud-wrapping station 19 and moves it towards the mud-wrapping station 19. For example... Figure 11 and Figure 15 When the filter cloth transfer vehicle 5 passes the filter cloth cleaning device 6, the roller 33 of the filter cloth cleaning device 6 falls, clamping the filter cloth between the roller 33 and the sludge plate 34, scraping off the sludge on the filter cloth. The sludge falls into the collection trough 35 and is transported away by the auger. After the previous filter cloth is removed, the first lifting mechanism 9 of the unpacking station 18 lifts up the next sludge bag.

[0084] Before the filter cloth transfer cart 5 reaches the mud-packing station 19, the mud-packing device 8 completes the packaging of the previous mud bag. Then, the first lifting mechanism 9 of the mud-packing station 19 drives the lifting pallet 23 to fall, causing the previously packaged mud bag to sink into the cage below the second opening of the mud-packing device 8, until the top of the mud bag is flush with the second rotating plates 44 around the mud-packing device 8. At this time, the filter cloth transfer cart 5 lays the cleaned filter cloth on the plane formed by the previous mud bag and the four second rotating plates 44. Then, the control roller 33 is raised, and the control filter cloth transfer cart 5 returns to the unpacking station 18 to grab the next filter cloth. At the same time, the height of the mud-clothing device 7 at the mud-packing station 19 is adjusted so that the distance between the bottom gate 29 and the filter cloth is equal to the set thickness of the mud bag. Then, the gate 29 is opened to let the sludge in the mud-clothing device 7 fall onto the filter cloth. Then, the gate 29 is closed, and the mud-clothing device 7 is raised again. Then, the four sets of cover cloth mechanisms of the sludge covering device 8 perform the following actions in sequence: the second moving frame 46 of the cover cloth mechanism on the corresponding side moves horizontally closer to the sludge, and at the same time, the second rotating plate 44 on the second moving frame 46 flips towards the sludge, covering the edge of the filter cloth onto the sludge. After that, the second moving frame 46 moves outward, and at the same time, the second rotating plate 44 returns to its original position. The cover cloth mechanism furthest from the unpacking station 18 operates first.

[0085] Once all the covering mechanisms have completed their actions, the mud bags are packaged. At this point, the first lifting mechanism 9 of the mud bagging station 19 is activated, causing the packaged mud bags to fall into the cage, awaiting the arrival of the next filter cloth.

[0086] During the working phase, the two sets of first lifting mechanisms 9, unpacking device 4, filter cloth transfer vehicle 5, filter cloth cleaning device 6 and mud wrapping device 8 work together in the manner described above until all mud bags in unpacking station 18 are unloaded and all filter cloths are transferred to mud wrapping station 19 and packaged onto new mud bags.

[0087] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
