Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and more particularly to a belt sludge dewatering machine. Background Technology

[0002] Belt conveyor sludge dewatering machines are widely used in wastewater treatment. They separate water from sludge using physical methods, thereby reducing sludge volume and enabling resource utilization. With increasing environmental awareness and technological advancements, belt conveyor sludge dewatering machines have found widespread application in municipal wastewater and industrial wastewater treatment. Traditional belt conveyor sludge dewatering machines mainly consist of a frame, dewatering conveyor belt, feeding system, and pressing system. They effectively remove most of the water from sludge, improving sludge treatment efficiency and economic benefits.

[0003] Traditional pressing systems typically use dewatering rollers to squeeze a dewatering mesh belt, thereby removing moisture from the sludge encased in the mesh belt. For example, a transmission mechanism drives the dewatering mesh belt through the gap between two dewatering rollers, causing the rollers to squeeze the mesh belt.

[0004] However, choosing the appropriate spacing between the two dewatering rollers is challenging. If the spacing is too large, the dewatering effect will be poor; if the spacing is too small, the dewatering mesh belt wrapped with sludge will have difficulty passing through the gap, increasing the resistance on the dewatering mesh belt and accelerating the wear and tear on the dewatering mesh belt and transmission mechanism. In addition, a gap that is too small may also cause the sludge wrapped by the dewatering mesh belt to leak and overflow from the edge of the dewatering mesh belt. Summary of the Invention

[0005] To address the issues of poor dewatering performance and sludge leakage, this application provides a belt sludge dewatering machine.

[0006] The belt sludge dewatering machine provided in this application adopts the following technical solution:

[0007] A belt sludge dewatering machine includes a frame, a dewatering mesh belt, a first dewatering component, and a second dewatering component;

[0008] The frame has a feeding area and a dehydration area;

[0009] The dewatering mesh belt passes through the feeding zone and the dewatering zone in sequence. The dewatering mesh belt includes a first mesh belt and a second mesh belt. In the feeding zone, a wedge-shaped opening is formed between the first mesh belt and the second mesh belt. The wedge-shaped opening is used for feeding sludge.

[0010] In the dehydration zone, the first mesh belt and the second mesh belt overlap to form the dehydration mesh belt;

[0011] The first dewatering component and the second dewatering component are both located in the dewatering zone. The first dewatering component includes multiple dewatering rollers distributed along an S-curve. All of the multiple dewatering rollers are rotatably connected to the frame. The dewatering mesh belt is sequentially wound around the multiple dewatering rollers.

[0012] The second dewatering assembly includes an installation frame, an edge sealing module, and a compression dewatering module. The dewatering mesh belt passes through the installation frame, which is connected to the machine frame. Both the edge sealing module and the compression dewatering module are located on the installation frame. The edge sealing module is used to bring the edges of the first mesh belt and the second mesh belt closer together and abut against each other. The compression dewatering module is used to compress the dewatering mesh belt.

[0013] By adopting the above technical solutions, belt sludge dewatering machines can achieve a highly efficient and stable sludge dewatering process. Specifically:

[0014] The first dewatering component consists of multiple dewatering rollers distributed along an S-curve, reducing space requirements. Furthermore, the multiple dewatering rollers compress the dewatering mesh belt during its movement, effectively removing moisture from the sludge.

[0015] The second dewatering component: The edge-sealing module ensures a tight seal between the edges of the first and second mesh belts, preventing sludge leakage and guaranteeing the dewatering effect. The extrusion dewatering module further improves the dryness of the sludge by extruding the dewatering mesh belts.

[0016] Preferably, the edge sealing module includes a first driving unit and two edge sealing blocks;

[0017] The two sealing blocks are respectively disposed on opposite sides of the dewatering mesh belt, and the sealing block has a sealing part on the side facing the dewatering mesh belt;

[0018] The first drive unit is disposed on the mounting frame and connected to the two edge sealing blocks. The first drive unit is used to drive the two edge sealing blocks to move closer or further away from each other, so as to clamp the edge of the dewatering mesh belt between the edge sealing portions of the two edge sealing blocks.

[0019] By adopting the above technical solution, the edge sealing module can effectively ensure that the dewatering conveyor belt maintains good sealing performance during the dewatering process and prevents sludge leakage. Specifically, the first drive unit can flexibly adjust the position of the two edge sealing blocks, making them closer to or further apart from each other, thereby achieving effective clamping of the edge of the dewatering conveyor belt and improving dewatering stability.

[0020] Preferably, the edge sealing portion is provided with edge sealing teeth, and the edge sealing teeth on the two edge sealing blocks are compatible in structure.

[0021] By adopting the above technical solution, the sealing part is provided with sealing teeth. The sealing teeth on the two sealing blocks are matched, which can enhance the sealing performance of the sealing blocks on the edge of the dewatering mesh belt, and also effectively increase the friction between the sealing blocks and the dewatering mesh belt, preventing the edge of the dewatering mesh belt from shifting or loosening during the dewatering process, thereby improving the dewatering efficiency and stability.

[0022] Preferably, the extrusion dehydration module includes a second drive unit and two extrusion plates;

[0023] The two extrusion plates are located on opposite sides of the dewatering mesh belt, and the extrusion plates are parallel to the portion of the dewatering mesh belt within the mounting frame.

[0024] The second drive unit is located on the mounting frame and connected to the two extrusion plates. The second drive unit is used to drive the two extrusion plates to move closer to or further away from each other.

[0025] By adopting the above technical solution, the two extrusion plates can effectively squeeze and dewater the sludge in the dewatering mesh belt, improving the dewatering effect. Simultaneously, the second drive unit can precisely control the distance between the two extrusion plates, ensuring the stability and reliability of the dewatering process. Furthermore, the parallel arrangement of the extrusion plates and the dewatering mesh belt results in a more uniform pressure distribution, further enhancing the dewatering effect.

[0026] Preferably, the portion of the dewatering mesh belt within the mounting frame is inclined.

[0027] By adopting the above technical solution, the dewatering mesh belt is partially inclined within the installation frame, so that the water discharged during the dewatering process can flow along the inclined direction, avoiding the discharged water from remaining on the extrusion plate.

[0028] Preferably, the mounting frame is slidably connected to the machine frame, and the sliding direction of the mounting frame is parallel to the transmission direction of the portion of the dewatering mesh belt within the mounting frame;

[0029] Within the mounting frame, the height of the dewatering mesh belt gradually increases along its transmission direction.

[0030] By adopting the above technical solution, the mounting frame is slidably connected to the machine frame. The sliding direction of the mounting frame is parallel to the transmission direction of the portion of the dewatering conveyor belt within the mounting frame. This allows the mounting frame to slide along the dewatering conveyor belt when it is clamped, eliminating the need for the conveyor belt to stop moving for dewatering, thus improving dewatering efficiency. Simultaneously, the height of the dewatering conveyor belt gradually increases along its transmission direction within the mounting frame, causing the height of the mounting frame to gradually increase during dewatering. When clamping the dewatering conveyor belt stops, the mounting frame can tilt and slide down under gravity to reset, facilitating subsequent clamping and dewatering of other parts of the conveyor belt.

[0031] Preferably, the mounting frame is slidably connected to the machine frame, and the sliding direction of the mounting frame is parallel to the transmission direction of the portion of the dewatering mesh belt within the mounting frame;

[0032] The second dehydration component further includes a third drive unit, which is connected to the mounting frame and is used to drive the mounting frame to slide.

[0033] By adopting the above technical solution, the third drive unit is connected to the mounting frame and used to drive the mounting frame to slide, so that no matter what the transmission direction is of the part of the dewatering mesh belt inside the mounting frame, the third drive unit can drive the mounting frame to move to complete the reset of the mounting frame.

[0034] Preferably, the third drive unit includes a reset cylinder, which is used to drive the mounting frame to slide in a direction opposite to the portion of the dewatering mesh belt that is located within the mounting frame.

[0035] By adopting the above technical solution, the reset cylinder can drive the mounting frame to slide in the opposite direction to the transmission direction of the dewatering mesh belt inside the mounting frame, so that the mounting frame can be quickly reset after completing one dewatering operation, thereby improving the working efficiency of the equipment.

[0036] Preferably, at least one of the dewatering rollers is provided with a plurality of drive teeth evenly spaced along the circumference, and the dewatering mesh belt is provided with through holes evenly spaced along its length direction corresponding to the drive teeth, the drive teeth being used to pass through the through holes.

[0037] By adopting the above technical solution, at least one dewatering roller is provided with multiple drive teeth evenly spaced along its circumference, and the dewatering mesh belt is provided with through holes evenly spaced along its length, corresponding to the drive teeth, through which the drive teeth pass. This design can improve the synchronization and stability between the dewatering mesh belt and the dewatering roller, reduce slippage, and prevent relative sliding between the first and second mesh belts, thereby improving dewatering efficiency and equipment reliability.

[0038] Preferably, at least one of the dewatering rollers is provided with an annular protrusion, and the dewatering mesh belt abuts against the annular protrusion.

[0039] By adopting the above technical solution, the annular protrusions on the dewatering roller can cause the dewatering mesh belt to bend at the annular protrusions, thereby preventing sludge from overflowing.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] The multiple dewatering rollers of the first dewatering component are distributed along an S-curve, reducing space occupation. Furthermore, the multiple dewatering rollers effectively remove moisture from the sludge by squeezing the dewatering mesh belt.

[0042] The sealing module and the extrusion dewatering module in the second dewatering component work together. The sealing module brings the edges of the dewatering mesh belt closer together and abuts against each other, preventing sludge from leaking from the edges. The extrusion dewatering module, on the other hand, significantly improves the dewatering rate and efficiency of the sludge by directly extruding the dewatering mesh belt.

[0054] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0055] like Figures 1 to 3As shown in the illustration, this application discloses a belt sludge dewatering machine, including a frame 1, a dewatering mesh belt 2, a first dewatering component 3, and a second dewatering component 4. The frame 1 has a feeding zone and a dewatering zone. The dewatering mesh belt 2 passes through the feeding zone and the dewatering zone sequentially. The dewatering mesh belt 2 includes a first mesh belt 21 and a second mesh belt 22. The frame 1 is equipped with two sets of drive components 5 for driving the first mesh belt 21 and the second mesh belt 22 to move. Each drive component 5 includes a motor, a reducer, and multiple guide rollers. The motor is connected to one of the guide rollers via the reducer, and by driving the guide roller to rotate, it drives either the first mesh belt 21 or the second mesh belt 22 to move. The transmission speeds of the first mesh belt 21 and the second mesh belt 22 are the same. The first mesh belt 21 and the second mesh belt 22 are used to clamp and squeeze the sludge, thereby dewatering the sludge.

[0056] Specifically, the first mesh belt 21 and the second mesh belt 22 have the same width, allowing moisture in the sludge to pass through. In the feeding zone, the first mesh belt 21 is positioned above the second mesh belt 22, forming a wedge-shaped opening 23 between them for sludge feeding. When sludge dewatering is required, the sludge is guided into the wedge-shaped opening 23 and falls onto the second mesh belt 22.

[0057] A feed hopper can be installed on the frame 1. Sludge can enter the wedge-shaped opening 23 through the feed hopper. The width of the feed hopper is smaller than the width of the second mesh belt 22, so that the sludge discharged from the feed hopper will not fall on the edge of the second mesh belt 22, reducing the risk of sludge overflow.

[0058] like Figures 1 to 2 As shown, rake teeth 6 can be installed above the second mesh belt 22. As the sludge moves with the second mesh belt 22, the rake teeth 6 can smooth the sludge as much as possible, facilitating the removal of water from the sludge under gravity. Furthermore, the rake teeth 6 can also discharge large particles from the sludge, preventing them from puncturing the first mesh belt 21 and the second mesh belt 22. The rake teeth 6 can be slidably connected to the frame 1 and can be driven by the cylinder 7 to move along the conveying direction of the second mesh belt 22, thereby better smoothing the sludge. Moreover, by driving the rake teeth 6 to move, large particles can be pushed out of the wedge-shaped opening 23, causing them to fall off the second mesh belt 22 and be removed.

[0059] As the sludge, after the removal of large particles, moves along the second mesh belt 22, the distance between the first mesh belt 21 and the second mesh belt 22 gradually decreases, and the first mesh belt 21 and the second mesh belt 22 enter the dewatering zone. In the dewatering zone, the first mesh belt 21 and the second mesh belt 22 overlap to form the dewatering mesh belt 2, and the sludge is wrapped between the first mesh belt 21 and the second mesh belt 22 and moves along the dewatering mesh belt 2.

[0060] The first dewatering component 3 and the second dewatering component 4 are both located in the dewatering zone. The first dewatering component 3 includes multiple dewatering rollers distributed along an S-curve. These rollers are rotatably connected to the frame 1 and are parallel to each other. The dewatering mesh belt 2 is sequentially wound around the rollers. The force applied by the rollers to the mesh belt 2 squeezes out most of the water from the sludge inside the mesh belt 2, completing the initial dewatering. When the projections of the rollers in the vertical direction overlap, a guide plate can be installed below the rollers to guide the discharged water and prevent it from falling onto other parts of the mesh belt 2.

[0061] Along the transmission direction of the dewatering mesh belt 2, the diameter of the multiple dewatering rollers gradually decreases, which gradually reduces the contact area between the multiple dewatering rollers and the dewatering mesh belt 2, and gradually increases the dewatering force of the multiple dewatering rollers on the dewatering mesh belt 2, so as to improve the dewatering effect.

[0062] like Figure 2 and Figure 4 As shown, further, at least one dewatering roller is provided with a plurality of transmission teeth 31 evenly spaced along its circumference, and the dewatering mesh belt 2 is provided with through holes 24 corresponding to the transmission teeth 31 evenly spaced along its length, with the transmission teeth 31 passing through the through holes 24. Specifically, both the first mesh belt 21 and the second mesh belt 22 are provided with through holes 24, and when the first mesh belt 21 and the second mesh belt 22 overlap to form the dewatering mesh belt 2, the through holes 24 on the two are aligned. Since the sludge distribution in the dewatering mesh belt 2 is not completely uniform before the initial dewatering, the sludge will move when squeezed, which may cause the first mesh belt 21 and the second mesh belt 22 to move with the sludge, and thus the dewatering mesh belt 2 may slide along the circumferential direction of the dewatering roller or the first mesh belt 21 and the second mesh belt 22 may be misaligned. Therefore, in this embodiment, the transmission teeth 31 are used to limit the first mesh belt 21 and the second mesh belt 22 to avoid the above situation.

[0063] Furthermore, transmission teeth 31 can also be provided on the guide roller in the drive assembly 5 to enhance the transmission force on the first mesh belt 21 and / or the second mesh belt 22, and prevent the first mesh belt 21 and / or the second mesh belt 22 from slipping on the guide roller.

[0064] like Figure 2 and Figure 4 As shown, at least one dewatering roller is provided with an annular protrusion 32. When the dewatering mesh belt 2 is wound around the dewatering roller, the annular protrusion 32 can abut against the dewatering mesh belt 2, thereby causing the dewatering mesh belt 2 to bend slightly at the annular protrusion 32. By causing the dewatering mesh belt 2 to bend slightly, the sludge in the dewatering mesh belt 2 is prevented from overflowing from the edge of the dewatering mesh belt 2.

[0065] like Figure 2 and Figure 3As shown, the second dewatering component 4 includes an installation frame 41, an edge sealing module 42, and an extrusion dewatering module 43. The installation frame 41 is connected to the frame 1, and the dewatering mesh belt 2 after preliminary dewatering can pass through the installation frame 41.

[0066] The edge sealing module 42 includes a first drive unit 421 and two edge sealing blocks 422. The two edge sealing blocks 422 are respectively disposed on opposite sides of the dewatering mesh belt 2 and are slidably connected to the mounting frame 41. The edge sealing block 422 has an edge sealing portion 4221 on the side facing the dewatering mesh belt 2. The first drive unit 421 is disposed on the mounting frame 41 and connected to the two edge sealing blocks 422. The first drive unit 421 is used to drive the two edge sealing blocks 422 to move closer or further apart from each other, so as to clamp the edge of the dewatering mesh belt 2 between the edge sealing portions 4221 of the two edge sealing blocks 422.

[0067] Specifically, the first drive unit 421 may include a first motor 4211 and a bidirectional lead screw 4212. The bidirectional lead screw 4212 is rotatably connected to the mounting frame 41. One nut of the bidirectional lead screw 4212 is connected to one of the edge sealing blocks 422, and the other nut is connected to the other edge sealing block 422. The bidirectional lead screw 4212 is connected to the first motor 4211. The first motor 4211 drives the bidirectional lead screw 4212 to rotate, thereby causing the two edge sealing blocks 422 to move closer or further apart. When the two edge sealing blocks 422 move closer together, the sealing portions 4221 of the two edge sealing blocks 422 will cause the edges of the first mesh belt 21 and the second mesh belt 22 to approach and abut against each other, thereby preventing sludge from overflowing between the first mesh belt 21 and the second mesh belt 22.

[0068] Furthermore, the sealing portion 4221 is provided with sealing teeth, and the sealing teeth on the two sealing blocks 422 are structurally compatible. When the two sealing blocks 422 abut against each other, the sealing teeth on them can interlock. Therefore, when the two sealing blocks 422 clamp the two sides of the dewatering mesh belt 2, the edge of the dewatering mesh belt 2 will bend in a wavy shape according to the shape of the sealing teeth, thereby improving the sealing performance of the sealing blocks 422 on the edge of the dewatering mesh belt 2.

[0069] The extrusion dewatering module 43 includes a second drive unit 431 and two extrusion plates 432. The two extrusion plates 432 are located on opposite sides of the dewatering mesh belt 2, and are parallel to the portion of the dewatering mesh belt 2 within the mounting frame 41. The extrusion plates 432 are slidably connected to the edge sealing block 422 or the mounting frame 41, and can slide closer to or further away from the dewatering mesh belt 2. The second drive unit 431 is located on the mounting frame 41 and connected to the two extrusion plates 432. The second drive unit 431 can be a drive cylinder. For example, two drive cylinders can drive the two extrusion plates 432 closer to or further away from each other, thereby extruding the dewatering mesh belt 2 and completing secondary dewatering. Compared to extruding sludge by tensioning the dewatering mesh belt 2, extruding the dewatering mesh belt 2 using the extrusion dewatering module 43 can apply greater extrusion force to the sludge without worrying about damage to the dewatering mesh belt 2. The edges of the dewatering mesh belt 2 have been sealed, so even if a large amount of pressure is applied to the dewatering mesh belt 2, there is no need to worry about sludge overflowing.

[0070] In some embodiments, the portion of the dewatering conveyor belt 2 within the mounting frame 41 is inclined. The mounting frame 41 is slidably connected to the machine frame 1, and the sliding direction of the mounting frame 41 is parallel to the transmission direction of the portion of the dewatering conveyor belt 2 within the mounting frame 41. Within the mounting frame 41, the height of the dewatering conveyor belt 2 gradually increases along its transmission direction.

[0071] Specifically, since the extrusion plate 432 is parallel to the portion of the dewatering mesh belt 2 within the mounting frame 41, the extrusion plate 432 is also inclined. The water squeezed out by the extrusion plate 432 can slide down along the extrusion plate 432, avoiding water retention. Furthermore, the mounting frame 41 is slidably connected to the frame 1. During the secondary dewatering process, the sealing module 42 and the extrusion dewatering module 43 in the second dewatering assembly 4 can clamp the dewatering mesh plate, allowing the second dewatering assembly 4 to move synchronously with the dewatering mesh plate. This eliminates the need to stop the dewatering mesh belt 2 for secondary dewatering, improving dewatering efficiency. Further, within the mounting frame 41, the height of the dewatering mesh belt 2 gradually increases, meaning the height of the second dewatering assembly 4 also gradually increases. After the secondary dewatering is completed, the second dewatering assembly 4 can automatically slide back to its original position under gravity, allowing for dewatering of other parts of the dewatering mesh belt 2.

[0072] In some embodiments, the mounting frame 41 is slidably connected to the frame 1, and the sliding direction of the mounting frame 41 is parallel to the transmission direction of the portion of the dewatering mesh belt 2 within the mounting frame 41. The second dewatering assembly 4 further includes a third drive unit 44, which is connected to the mounting frame 41 and used to drive the mounting frame 41 to slide.

[0073] Specifically, the mounting frame 41 is slidably connected to the frame 1, which provides the prerequisite for the second dewatering component 4 to move synchronously with the dewatering mesh belt 2. The mounting frame 41 can be driven to move by the third drive unit 44, so that regardless of the transmission direction of the dewatering mesh belt 2, the second dewatering component 4 can move with the dewatering mesh belt 2 during the secondary dewatering process and reset after the secondary dewatering is completed.

[0074] Since the second dewatering component 4 can move along with the dewatering mesh belt 2 by clamping it, the third drive unit 44 only needs to reset the second dewatering component 4. The third drive unit 44 can be a reset cylinder, which is located on the frame 1. After the secondary dewatering is completed, the second dewatering component 4 can be reset by pushing the mounting frame 41 in the opposite direction to the part of the dewatering mesh belt 2 that is inside the mounting frame 41.
