Description

Technical Field

[0002] Sludge is a product of the treatment process of domestic sewage and industrial wastewater. It is a slurry composed of solid impurities, suspended solids and colloidal substances. In essence, it is the solid part of sewage. Sludge is a solid waste. In order to treat sludge, it needs to be shaped into a certain form for subsequent collection and treatment. This requires the use of a cloth-laying machine.

[0012] Preferably, two symmetrically arranged reinforcing plates are fixedly connected to the frame platform, and rubber blocks are fixedly connected to the inner side of each reinforcing plate.

[0013] Preferably, two sets of second sliding rods are symmetrically arranged and slidably connected to both sides of the frame plate.

[0016] The beneficial effects of this invention are: 1. This invention achieves sludge conveying by using a conveyor motor to drive the active shaft, which in turn works with the passive shaft and belt. Simultaneously, an oscillating motor drives a swing arm to slide within a chute and a rolling wheel to roll along a swing track, causing the oscillating mechanism to drive the conveying mechanism to oscillate left and right, achieving uniform distribution of low-moisture sludge. The structure is simple and reasonable. The drive device drives two first chute plates to move towards each other in the lower inclined chute of the feed inlet, which can reduce the feed volume. Subsequently, the second chute plate is moved in the lower inclined chute of the discharge outlet by a support linkage, which reduces the discharge volume. This effectively controls the conveying volume per unit time, avoids excessive feed leading to uneven sludge accumulation thickness, and further improves the uniformity of distribution. At the same time, when the conveyor motor starts, it drives the passive shaft through gear meshing and sprocket chain transmission, causing the two rolling rollers to rotate synchronously, rolling and shaping the sludge, which is convenient for uniform spreading during oscillating distribution and enhances the distribution effect.

[0017] 2. In this invention, when the fabric spreading machine swings and spreads the fabric, the two side plates are repeatedly squeezed by rubber blocks, causing the two elastic horizontal plates to move sequentially. This limits the sludge on the belt and promotes its concentration towards the center, effectively preventing the sludge from spilling to both sides due to the swinging inertia. This ensures a stable and reliable fabric spreading process. During the fabric spreading process, the motor drives the cam to rotate, causing the squeezing roller to move the elastic limiting plate downwards. This, together with the inclined plate on one side of the limiting plate, blocks the sludge, allowing all the sludge to enter below the limiting plate. This allows for flexible control of the fabric thickness, preventing localized sludge accumulation or uneven thickness.

[0018] 3. In this invention, when the fabric is swung left and right by the swinging device, the frame plate sequentially presses the elastic round seat, causing the third slide rod to extend and retract in the vertical plate, absorbing the impact energy of the reversal and reducing mechanical wear. At the same time, the sliding frame further consumes the swinging kinetic energy, avoiding excessive swinging. The double buffer effectively protects the equipment and significantly extends the service life of the fabric laying machine. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-11 As shown, the present invention is a uniform feeding machine suitable for sludge with low moisture content, including a frame plate 1, a swing device on the frame plate 1, a conveying mechanism on the swing device, the swing device is used to drive the conveying mechanism to swing back and forth, the conveying mechanism includes a frame plate 47 located above the frame plate 1, a feed inlet 13 is fixedly connected to the frame plate 47, a discharge outlet 14 is fixedly connected to the opening at one end of the frame plate 47, and a downward inclined groove 17 is opened at both ends of the feed inlet 13 and one side of the discharge outlet 14; Two symmetrically arranged first chute 15s slide inside the two lower inclined chute 17, and a second chute 18 slides inside the other lower inclined chute 17. A drive device 16 is fixedly connected to one side of the frame plate 47. The drive device 16 is used to drive the two first chute 15s to move towards each other or relative to each other, and to drive the second chute 18 to move synchronously. Two symmetrically arranged rolling rollers 20 are rotatably connected inside the feed inlet 13. The two first chute 15s and the second chute 18 are all in an inclined state, so that the sludge can move downward smoothly, ensuring smoother sludge feeding and discharging.

[0024] The swing device includes a rotating assembly 2 rotatably connected to the frame platform 1 via a swing motor 6. A swing rod 3 is fixedly connected to the rotating assembly 2. A swing slide 4 is rotatably connected to the frame platform 1. A slide groove 5 is provided on the swing slide 4. The swing rod 3 is slidably placed in the slide groove 5 of the swing slide 4. An arc-shaped swing rail 8 is fixedly connected to the frame platform 1. A base plate is fixedly connected to the lower side of the swing slide 4. A rolling wheel 7 is rotatably connected to one side of the base plate. The rolling wheel 7 is always located on the swing rail 8.

[0025] The conveying mechanism includes a drive shaft 9 rotatably connected inside the frame plate 47 via a conveying motor 12, a driven shaft 10 rotatably connected inside the frame plate 47, and belts 11 sleeved on the drive shaft 9 and the driven shaft 10.

[0026] A bracket 19 is fixedly connected to one side of the second slide 18. One side of the two rolling rollers 20 passes through the feed inlet 13 and extends to the other side of the feed inlet 13. Gears 21 are fixedly connected to one side of each of the two rolling rollers 20, and the two gears 21 mesh with each other. The other side of the rolling rollers 20 passes through the feed inlet 13 and extends to the other side of the feed inlet 13. The other side of the driven shaft 10 passes through the frame plate 47 and extends to the other side of the frame plate 47. Sprockets 22 are fixedly connected to the other side of the driven shaft 10 and the other side of the rolling rollers 20. Chains 23 are sleeved on the two sprockets 22. With the use of the two gears 21, sprockets 22, chains 23 and driven shaft 10, when the conveyor motor 12 is started, it can drive the two rolling rollers 20 to rotate together. At this time, they are driven by the same source, which is simple in structure and effectively saves resources.

[0027] Furthermore, the drive device 16 is a bidirectional screw drive mechanism. The output shaft of the servo motor drives the bidirectional screw to rotate. Two symmetrically arranged mounting plates are threaded onto the bidirectional screw. The two first slides 15 are respectively fastened to the two mounting plates. One of the mounting plates is fastened to the bracket 19. In this way, the two mounting plates on the bidirectional screw can move towards each other or relative to each other, so that the two first slides 15 and the second slide 18 can be adjusted synchronously to control the feed size of the feed port 13 and the discharge size of the discharge port 14. The drive device 16 is prior art and is not limited thereto.

[0028] It can be explained that when the drive device 16 drives the two first chute plates 15 to move towards each other, their inner edges gradually approach each other, forming a gradually narrowing feed inlet 13, so that the sludge falls to the middle of the belt 11 in a more concentrated manner. At the same time, the support 19 moves synchronously with the first chute plate 15. The support 19 drives the second chute plate 18 to perform the same direction adjustment in the lower inclined groove 17 of the discharge port 14, so that the opening width of the discharge port 14 and the feed inlet 13 are linked and adjusted to ensure the dynamic balance between the feed rate and the discharge rate. The drive adjustment mechanism enables the control of the cloth thickness according to the actual moisture content of the sludge.

[0029] A first slide rod 24 is slidably connected to the frame plate 47. The lower side of the first slide rod 24 passes through the frame plate 47 and extends into the frame plate 47. A limit plate 25 is fixedly connected to the lower side of the first slide rod 24. An inclined plate 26 is fixedly connected to the side of the limit plate 25 near the feed port 13. A top plate 27 is fixedly connected to the first slide rod 24. A first spring 28 is connected in an array between the top plate 27 and the frame plate 47.

[0030] A U-shaped plate 32 is fixedly connected to the top plate 27. A roller 31 is rotatably connected inside the U-shaped plate 32. A fixing plate 29 is fixedly connected to the frame plate 47. A cam 30 is rotatably connected to one end of the fixing plate 29 via a motor. The lower side of the cam 30 is attached to the outer surface of the roller 31.

[0031] It can be explained that when the sludge on the belt 11 is thick, the protrusion of the cam 30 quickly rotates onto the roller 31, causing the limiting plate 25 to press down to reduce the subsequent sludge. When the sludge layer is thin, the base circle of the cam 30 contacts the roller 31, and the limiting plate 25 moves upward under its own elastic restoring force, reducing the pressure on the sludge and allowing subsequent sludge to be replenished to the area of ​​the limiting plate 25. The inclination angle of the inclined plate 26 is designed to be between 45 and 60 degrees, which can effectively guide the sludge flow without excessive squeezing and shearing of the sludge, thus avoiding damage to the sludge structure and affecting the subsequent treatment effect.

[0032] Two symmetrically arranged reinforcing plates 33 are fixedly connected to the frame platform 1, and rubber blocks 34 are fixedly connected to the inner side of each of the two reinforcing plates 33.

[0033] Two sets of second slide rods 35 are symmetrically arranged and slidably connected to both sides of the frame plate 47. The inner sides of the two sets of second slide rods 35 penetrate the frame plate 47 and extend into the frame plate 47. The inner sides of the two sets of second slide rods 35 are fixedly connected to a horizontal plate 36. The inner sides of the two horizontal plates 36 are fixedly connected to an inclined baffle 37. The two horizontal plates 36 and the frame plate 47 are connected in an array of second springs 38. The side plate 39 is fixedly connected to the side of the two sets of second slide rods 35 near the outside of the frame plate 47. The side plate 39 and the rubber block 34 are at the same height.

[0034] When the oscillating mechanism swings the cloth left and right, the two side plates 39 are squeezed by the two rubber blocks 34 in turn, so that the two elastic horizontal plates 36 can move in turn. By using the baffle 37 on the inner side of the horizontal plate 36, the guide slope of the baffle 37 will form an inward guiding effect on the edge of the sludge, and will also promote the sludge to gather towards the middle of the belt 11, preventing the sludge from overflowing to both sides due to the oscillation inertia. No additional drive source is required. At the same time, during the elastic reset process, the horizontal plate 36 can further strike the sludge, making the sludge more compact and concentrated. In addition, both horizontal plates 36 have an effective limit state, thereby ensuring the continuity and stability of sludge transportation throughout the entire oscillating cloth feeding cycle. This solves the defect of easy formation of cloth dead zone or sludge accumulation during oscillating cloth feeding. At the same time, the sludge is evenly distributed and shaped into a certain shape, which is convenient for subsequent centralized treatment of sludge as a solid waste.

[0035] Two symmetrically arranged vertical plates 40 are fixedly connected to the swing rail 8. A third slide rod 41 is slidably connected to the inner side of each of the two vertical plates 40. A round seat 42 is fixedly connected to the inner side of each of the two third slide rods 41. One side of the third slide rod 41 passes through the vertical plate 40 and extends to the other side of the vertical plate 40. A third spring 43 is fixedly connected between the two round seats 42 and the vertical plate 40. The round seats 42 and the swing slide 4 are at the same height.

[0036] A U-shaped seat 44 is fixedly connected to the top of the frame platform 1. Two smooth rods 45 are fixedly connected inside the two U-shaped seats 44. Two symmetrically arranged sliding frames 46 are slidably connected to the two smooth rods 45. The inner sides of the two sliding frames 46 are respectively fastened to one side of the two third sliding rods 41. Two fourth springs 48 are fixedly connected between the two sliding frames 46. When the swing device swings left and right to distribute the material, it will squeeze the elastic round seat 42 in sequence, causing the third sliding rod 41 to move. At the same time, the third sliding rod 41 will also drive the sliding frame 46 to move. When the sliding frame 46 moves, it will also pull the connected fourth spring 48. The elastic deformation process of the fourth spring 48 will reduce the risk of damage to the swing mechanism by the instantaneous impact force. When the swing device completes the reversal, the restoring force of the fourth spring 48 will help the sliding frame 46 quickly return to the initial position, preparing for the next swing cycle. The combination design of double buffer and energy absorption makes the swing device maintain a stable operating state during high-speed reciprocating motion, which significantly improves the uniformity of material distribution and the reliability of continuous operation of the material distribution machine for sludge with low water content.

[0037] In use, the sludge enters through the inlet 13, and the drive shaft 9 rotates under the drive of the conveyor motor 12. Combined with the transmission of the driven shaft 10 and the belt 11, the belt 11 transports the sludge, which then falls from the outlet 14. Subsequently, the rotating assembly 2 rotates under the drive of the swing motor 6. The swing arm 3 slides back and forth in the groove 5 of the swing slide 4, and the rolling wheel 7 rolls on the swing rail 8, thus driving the swing slide 4 to swing left and right. When the conveyor motor 12 and the swing motor 6 work simultaneously, the sludge can be swung left and right for distribution. This type of distribution machine is suitable for sludge with low moisture content, achieving uniform distribution. It has a simple and reasonable structure. Next, the drive device 16 is activated. The drive device 16 drives the two first chute plates 15 to move towards each other in the two lower inclined grooves 17 of the inlet 13, thus reducing the distance between the two chute plates. When the two first slides 15 move towards each other, the feed rate of the small feed port 13 will also drive the support 19 to move and adjust. In this way, the support 19 will drive the second slide 18 to move in the lower inclined groove 17 of the discharge port 14 to reduce the discharge rate of the discharge port 14. This will effectively control the amount of sludge conveyed per unit time and avoid the problem of uneven sludge accumulation on the belt 11 due to excessive feed. This will further achieve uniform material distribution. At the same time, by using the meshing transmission of the two gears 21 and the transmission of the sprocket 22 and chain 23, when the conveyor motor 12 starts, it will drive the driven shaft 10 to rotate, so that the two rolling rollers 20 can rotate synchronously. At this time, the two rolling rollers 20 can also roll the input sludge, enhance the shaping effect of the sludge, facilitate the uniform spreading during the swinging material distribution process, and improve the uniformity of the material distribution. When the oscillating device swings the fabric left and right, the two side plates 39 are repeatedly squeezed by the two rubber blocks 34, causing the two elastic horizontal plates 36 in the oscillating device to move sequentially. This allows both horizontal plates 36 to limit the sludge conveyed on the belt 11, causing the sludge to gather towards the center of the belt 11 and preventing it from overflowing to both sides due to oscillation inertia. This ensures the stability of the fabric distribution machine during operation. During the sludge oscillation and fabric distribution process, the motor can also be started, which will drive the cam 30 to rotate. As the cam 30 rotates, it squeezes... Roller 31 moves downward, which squeezes the elastic limiting plate 25 and causes the limiting plate 25 to move down. This allows for flexible adjustment of the height of the limiting plate 25. In addition, the inclined plate 26 on one side of the limiting plate 25 can block the sludge during transportation, allowing all the sludge to enter below the limiting plate 25 and controlling the thickness of the sludge cloth. This effectively avoids the local accumulation or uneven thickness of the sludge during transportation. When the cam 30 continues to rotate, the cam 30 will gradually release the squeezing limiting plate 25, allowing the limiting plate 25 to return to its initial height. When the swinging device swings the fabric left and right, the frame plate 47 of the swinging device will sequentially squeeze the two elastic round seats 42, causing the two third slide rods 41 to extend and retract between the two vertical plates 40. At this time, the two elastic round seats 42 can absorb the impact energy generated when the swinging device reverses direction, reduce the mechanical wear of the entire swinging mechanism, and thus buffer and protect the entire swinging device. Subsequently, the extension and retraction of the two third slide rods 41 will also drive the two elastic sliding frames 46 to slide on the two sliding frames 46, further consuming the kinetic energy generated by the swinging, avoiding excessive swinging, and extending the service life of the equipment.
