Description

Technical Field

[0001] This utility model relates to the field of sludge drying, specifically a sludge drying device for sludge treatment. Background Technology

[0002] Silt management is a comprehensive project that mainly involves using dredging equipment to remove silt from river channels, thereby improving the water quality of rivers, lakes and other water bodies, helping them restore their ecological functions and enhancing the city's image.

[0003] Because sludge contains a large amount of water, if the cleaned sludge is discharged directly, it is easy for bacteria, viruses and other microorganisms to grow, producing a foul odor and polluting the surrounding environment. Therefore, sludge is usually treated by a sludge drying device. The volume and mass of the treated sludge will be reduced, which makes it easier to transport and process.

[0004] However, during the sludge drying process, as the moisture gradually evaporates, the sludge is prone to clumping. These clumps can hinder the effective heating of the internal sludge, leading to uneven heat distribution, which in turn affects the evaporation rate of moisture and ultimately reduces the drying efficiency. Therefore, a sludge treatment and drying device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a sludge treatment and sludge drying device.

[0013] The advantages of this utility model are:

[0014] 1. The sludge drying device for sludge treatment described in this utility model uses stirring blades to agitate the sludge inside the drying cylinder, breaking up clumps of sludge. This prevents clumps from forming during the drying process as moisture evaporates, which can hinder effective heating of the sludge, causing uneven heat distribution and affecting the drying process and efficiency. A servo motor drives the drying cylinder to rotate in the opposite direction while simultaneously agitating the stirring blades in the forward direction, creating two opposing movements. This results in continuous circulation of the sludge inside the drying cylinder, improving the uniformity of heating and accelerating the drying rate.

[0015] 2. The sludge drying device for sludge treatment described in this utility model, through the cooperation of the limiting disc and the limiting groove, can support the sludge drying cylinder, thereby improving the stability of the sludge drying cylinder when rotating in the middle of the drying rack.

The rollers can assist the limiting disc in supporting the sludge drying cylinder, thereby reducing the load on the sludge drying cylinder. At the same time, the rotational characteristics of the rollers can also reduce the friction between them and the drying rack, making the rotation of the sludge drying cylinder smoother.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a sludge drying device for sludge treatment includes a drying rack 1 and a support assembly; a sludge drying cylinder 11 is installed in the middle of the drying rack 1; a drive shaft 12 is rotatably connected inside the drying rack 1; two sets of drive gears 13 are fixedly connected in the middle of the drive shaft 12; two sets of gear slots 14 are opened in the middle of the drying rack 1; two sets of ring gears 15 are fixedly connected in the middle of the sludge drying cylinder 11; the ring gears 15 mesh with the drive gears 13; a servo motor 16 is connected to one end of the drive shaft 12; the sludge drying cylinder 11 rotates in the middle. A driven shaft 17 is connected; pulleys 18 are fixedly connected to one end of both the driven shaft 17 and the drive shaft 12; a transmission belt 19 is connected to the middle of each pulley 18; multiple sets of stirring blades 111 are fixedly connected to the middle of the driven shaft 17; during operation, when sludge is placed inside the sludge drying cylinder 11 for drying, the servo motor 16 can be activated to drive the drive shaft 12 to rotate in the middle of the drying rack 1. The rotation of the drive shaft 12 will drive the drive gear 13 to rotate synchronously at the gear slot 14. Because the drive gear 13 and the ring gear 15 are in a meshing state... Therefore, the rotation of the drive gear 13 can drive the ring gear 15 to rotate in the opposite direction, and the rotation of the ring gear 15 can simultaneously drive the sludge drying cylinder 11 to rotate in the opposite direction. At this time, the two sets of pulleys 18 are connected to each other by the transmission belt 19, so that the torque of the drive shaft 12 can drive the driven shaft 17 to rotate in the same direction through the transmission belt 19. The rotation of the driven shaft 17 can drive the stirring blades 111 to stir inside the sludge drying cylinder 11. This step, through the stirring effect of the stirring blades 111 on the sludge inside the sludge drying cylinder 11, can remove the clumps. The sludge is broken up to prevent clumping during the drying process as moisture evaporates. These clumps can hinder the effective heating of the sludge inside, causing uneven heat distribution and affecting the drying process and efficiency. The servo motor 16 drives the sludge drying cylinder 11 to rotate in the opposite direction and simultaneously drives the stirring blades 111 to stir in the forward direction. This creates two opposing movements, resulting in continuous circulation of the sludge inside the sludge drying cylinder 11, thereby improving the uniformity of heating and accelerating the drying rate.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, the support assembly includes a limiting disc 2, a limiting groove 21, an L-shaped guide post 22, a U-shaped plate 23, a rotating shaft 24, and a roller 25. Two sets of limiting discs 2 are fixedly connected to the middle of the sludge drying cylinder 11. Two sets of limiting grooves 21 are opened in the middle of the drying rack 1. The limiting discs 2 and the limiting grooves 21 are in close contact with each other. L-shaped guide posts 22 are fixedly connected to both ends of the limiting discs 2. U-shaped plates 23 are fixedly connected to the bottom of the L-shaped guide posts 22. A rotating shaft 24 is rotatably connected to the middle of the U-shaped plate 23. A roller 25 is fixedly connected to the middle of the rotating shaft 24. During operation, when the sludge drying cylinder 11 rotates, it will drive the limiting discs 2 to rotate in the middle of the limiting grooves 21. The rotation of the limiting discs 2 will simultaneously drive the L-shaped guide posts 22, U-shaped plates 23, rotating shaft 24, and rollers 25 to rotate. When the rollers 25 rotate to the drying rack 1, they will interact with the drying rack 1. When the surfaces come into contact and friction occurs, the roller 25, under the action of friction, will drive the rotating shaft 24 to rotate in the middle of the U-shaped plate 23. This step, through the cooperation of the limiting disc 2 and the limiting groove 21, can support the sludge drying cylinder 11, thereby improving the stability of the sludge drying cylinder 11 when rotating in the middle of the drying rack 1. At the same time, it can also limit the rotation trajectory of the sludge drying cylinder 11, reducing the possibility of the sludge drying cylinder 11 shifting back and forth due to uneven force during rotation, which would affect the meshing state of the drive gear 13 and the ring gear 15. The roller 25 can assist the limiting disc 2 in supporting the sludge drying cylinder 11, thereby reducing the load on the sludge drying cylinder 11. At the same time, the rotation characteristics of the roller 25 can also reduce the friction between it and the drying rack 1, thus making the rotation of the sludge drying cylinder 11 smoother.

[0027] like Figure 3 , Figure 5 As shown, multiple sets of support rods 3 are fixedly connected to the middle of the driven shaft 17; each support rod 3 has a crossbar 31 fixedly connected to its top; each crossbar 31 has a rubber scraper 32 fixedly connected to its middle; the rubber scraper 32 is in contact with the inner wall of the sludge drying cylinder 11; during operation, when the driven shaft 17 rotates, it will drive the support rods 3 and crossbars 31 to rotate synchronously, and the rubber scraper 32 will rotate with the rotation of the crossbars 31. Because the rubber scraper 32 is in contact with the inner wall of the sludge drying cylinder 11, the rotation of the rubber scraper 32 can effectively dry the sludge. The inner wall of the sludge drying cylinder 11 is cleaned. This step is necessary because when the sludge inside the sludge drying cylinder 11 is broken up, some of the particles produced are easily splashed onto the inner wall of the sludge drying cylinder 11 due to the force. This makes it difficult for the stirring blades 111 to break up the particles adhering to the inner wall again, thus affecting the overall operation of the stirring blades 111 and resulting in a decrease in the drying rate of the sludge on the inner wall. At this time, the cleaning of the inner wall of the sludge drying cylinder 11 by the rubber scraper 32 can reduce the occurrence of such phenomena.

[0028] like Figure 4 , Figure 6 As shown, each roller 25 has a groove 4 in the middle; two sets of semi-circular guide rails 41 are fixedly connected to the middle of the drying rack 1; the groove 4 and the semi-circular guide rails 41 fit together; during operation, when the roller 25 rotates, it will drive the groove 4 to roll along the surface of the semi-circular guide rail 41, and the groove 4 is restricted by the semi-circular guide rail 41 when rolling, so that it always moves along the same trajectory. This step, through the cooperation of the groove 4 and the semi-circular guide rail 41, can play the role of restricting the rotation trajectory of the limiting disc 2, thereby further restricting the rotation trajectory of the sludge drying cylinder 11 in conjunction with the limiting disc 2 and the limiting groove 21, thereby further improving the stability of the position of the sludge drying cylinder 11 during rotation.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown, brush plates 5 are fixedly attached to the four corners of the top of the drying rack 1; multiple sets of bristles 51 are connected to the middle of the brush plates 5; one end of each bristle 51 contacts the surface of the ring gear 15; during operation, when the ring gear 15 rotates, its surface will contact and rub against the bristles 51. Under friction, the bristles 51 can clean the surface of the ring gear 15. This step, by cleaning the ring gear 15, can reduce the dust accumulated on the surface of the ring gear 15, thereby preventing the ring gear 15 from easily accumulating a large amount of dust due to the influence of the working environment, which would affect its meshing state with the drive gear 13.

[0030] like Figure 2 As shown, a support column 6 is fixedly connected to one side of the drying rack 1; a support disc 61 is fixedly connected to the top of the support column 6; during operation, the support column 6 and the support disc 61 serve to support the drive shaft 12, and when the drive shaft 12 rotates, it will rotate with the middle of the support disc 61. This step, by supporting the drive shaft 12, can improve the stability and reliability of the drive shaft 12 during rotation.

[0031] like Figure 1 , Figure 2 As shown, two sets of arc-shaped side wing plates 7 are fixed to one side of the drying rack 1; the arc-shaped side wing plates 7 are in contact with the two sides of the servo motor 16; during operation, when the servo motor 16 is working, it is prone to slight vibration. At this time, the arc-shaped side wing plates 7 can reduce the vibration amplitude of the servo motor 16. This step, through the function of the arc-shaped side wing plates 7, can improve the stability of the servo motor 16 during operation, thereby reducing the situation where the servo motor 16 is prone to increased vibration amplitude due to lack of support during operation, thus affecting its normal operation.

[0032] Working principle: During operation, when sludge is placed inside the sludge drying cylinder 11 for drying, the servo motor 16 operates, driving the drive shaft 12 to rotate in the middle of the drying rack 1. The rotation of the drive shaft 12 drives the drive gear 13 to rotate synchronously at the gear slot 14. Because the drive gear 13 and the ring gear 15 are meshed, the rotation of the drive gear 13 can drive the ring gear 15 to rotate in the opposite direction. The rotation of the ring gear 15 can simultaneously drive the sludge drying cylinder 11 to rotate in the opposite direction. At this time, the two sets of pulleys 18 are connected by the transmission belt 19, so that the torque of the drive shaft 12 can drive the driven shaft 17 to rotate in the same direction through the transmission belt 19. The rotation of the driven shaft 17 can drive the stirring blades 111 to rotate in the same direction. The mud drying cylinder 11 is stirred inside. This step involves stirring the mud inside the cylinder 11 using stirring blades 111. This breaks up any clumps of mud, preventing them from clumping together during the drying process as moisture evaporates. Clumps can hinder effective heating of the mud, causing uneven heat distribution and affecting the drying process and efficiency. A servo motor 16 drives the mud drying cylinder 11 to rotate in the opposite direction while simultaneously driving the stirring blades 111 to stir in the same direction. This creates two opposing movements, resulting in continuous circulation of the mud inside the drying cylinder 11. This improves the uniformity of heating and accelerates the drying rate. During operation, the rotation of the mud drying cylinder 11 drives... The limiting disc 2 rotates in the middle of the limiting groove 21. The rotation of the limiting disc 2 simultaneously drives the L-shaped guide post 22, the U-shaped plate 23, the rotating shaft 24, and the roller 25 to rotate. When the roller 25 rotates to the drying rack 1, it contacts the surface of the drying rack 1 and generates friction. At this time, the frictional force of the roller 25 drives the rotating shaft 24 to rotate in the middle of the U-shaped plate 23. This step, through the cooperation of the limiting disc 2 and the limiting groove 21, supports the sludge drying cylinder 11, thereby improving the stability of the sludge drying cylinder 11 when rotating in the middle of the drying rack 1. It also limits the rotation trajectory of the sludge drying cylinder 11, reducing the likelihood of it shifting forward or backward due to uneven force during rotation, which could affect the drive gears. When the ring gear 15 is engaged with the roller 25, the roller 25 helps to support the sludge drying cylinder 11 by limiting the disc 2, thereby reducing the load on the sludge drying cylinder 11. Simultaneously, the rotation of the roller 25 reduces the friction between it and the drying rack 1, making the rotation of the sludge drying cylinder 11 smoother. During operation, when the driven shaft 17 rotates, it drives the support rod 3 and the crossbar 31 to rotate synchronously. Simultaneously, the rubber scraper 32 rotates with the crossbar 31. Because the rubber scraper 32 is in contact with the inner wall of the sludge drying cylinder 11, its rotation cleans the inner wall of the sludge drying cylinder 11. This step is crucial when the sludge inside the sludge drying cylinder 11 is broken up.Some of the particles generated are easily splashed onto the inner wall of the sludge drying cylinder 11 due to the force, making it difficult for the stirring blades 111 to further break up the particles adhering to the inner wall. This affects the overall work efficiency of the stirring blades 111 and leads to a decrease in the sludge drying rate on the inner wall. At this time, the rubber scraper 32 cleans the inner wall of the sludge drying cylinder 11, which can reduce the occurrence of this phenomenon. During operation, when the roller 25 rotates, it will drive the roller groove 4 to roll along the surface of the semi-circular guide rail 41. When the roller groove 4 rolls, it is restricted by the semi-circular guide rail 41, so that it always moves along the same trajectory. This step, through the cooperation of the roller groove 4 and the semi-circular guide rail 41, can restrict the rotation trajectory of the limiting disc 2. In this way, the limiting disc 2 and the limiting groove 21 further restrict the rotation trajectory of the sludge drying cylinder 11, thereby further improving the positional stability of the sludge drying cylinder 11 during rotation. During operation, when the ring gear 15 rotates, its surface will come into contact with the bristles 51. Friction is performed, allowing the bristles 51 to clean the surface of the ring gear 15. This cleaning process reduces dust accumulation on the ring gear 15, preventing dust buildup that could affect its meshing with the drive gear 13. During operation, the support column 6 and support disc 61 support the drive shaft 12, rotating with the center of the support disc 61. This support improves the stability and reliability of the drive shaft 12. When the servo motor 16 operates, it is prone to slight vibration. The arc-shaped side plate 7 reduces this vibration, improving the stability of the servo motor 16 and preventing excessive vibration due to lack of support, which could affect its normal operation.
