Description

Technical Field

[0001] This invention belongs to the field of sludge treatment technology, and in particular relates to a reciprocating sludge extrusion drying device. Background Technology

[0002] With the acceleration of urbanization and the continuous development of industrial production, the output of sewage sludge is increasing day by day. If sewage sludge is not properly treated, it will not only cause serious pollution to the environment, but also occupy a large amount of land resources.

[0003] In existing sludge drying equipment, a motor-driven auger continuously propels wet sludge forward in the extrusion cylinder. A baffle at the outlet of the extrusion cylinder blocks the sludge, causing it to accumulate and compress, thus draining the water from the sludge. When the pressure of the sludge accumulated in the extrusion cylinder becomes too high, the baffle will be pushed off the cylinder by the sludge, allowing the dewatered sludge to be discharged. However, because the sludge is compacted by the auger, there is an adhesion between the sludge pushed out of the extrusion cylinder and the sludge that is not pushed out. At this point, the sludge pushed to the outside of the extrusion cylinder cannot be detached from the sludge drying equipment, causing an increase in internal pressure and blockage of the equipment, thereby affecting the efficiency of the sludge drying equipment in processing wet sludge. Summary of the Invention

[0009] Furthermore, the sealing plate is also provided with a twisting component, which includes a plurality of clamping rods arranged in an array on the side of the sealing plate near the discharge cylinder. A rotating cylinder is provided on the side of the sealing plate away from the clamping rods. A movable cylinder is sleeved on the outside of the rotating cylinder. Guide blocks are symmetrically arranged on the outside of the rotating cylinder. The guide blocks are slidably disposed in the spiral groove on the inner wall of the movable cylinder.

[0010] Furthermore, a guide cylinder is provided on the outer side of the movable cylinder, one end of which is fixedly connected to the mounting frame. Keyways are symmetrically provided on the inner wall of the guide cylinder, and the extension direction of the keyways is parallel to the axis of the guide cylinder. Guide posts are symmetrically provided on the outer wall of the movable cylinder, and the guide posts are slidably installed in the keyways.

[0011] Furthermore, a first plug is provided at the end of the guide cylinder away from the mounting bracket. The axis of the first plug coincides with the axis of the guide cylinder. A first piston is slidably connected inside the first plug. The first piston is connected to the middle area of ​​the end of the moving cylinder away from the sealing plate via a connecting rod. The connecting rod passes through the bottom surface of the guide cylinder and is slidably connected to the bottom surface of the guide cylinder.

[0012] Furthermore, the twisting component also includes a second plug cylinder, in which a second piston is slidably connected. A push rod is provided on one side of the second piston, and the push rod is perpendicular to the second piston.

A push rod is provided on the side of the second piston away from the push rod, and the axis of the push rod coincides with the axis of the second piston.

[0013] Furthermore, the bottom of the second plug cylinder is provided with an exhaust groove, which has a frustum-shaped structure. A movable column is slidably connected inside the exhaust groove.

The bottom of the movable cavity is connected to the first plug through an air pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the pressure of sludge accumulation to push the sealing plate, causing the top block to push and slice the columnar sludge. Simultaneously, the mounting frame pushes the push rod, which in turn pushes the moving column. At this time, the air pressure inside the first plug cylinder increases, and the first piston drives the moving cylinder to move, which in turn causes the rotating cylinder to rotate the sealing plate. The sealing plate then rotates the columnar sludge extending out of the discharge cylinder through the clamping rod. The part of the columnar sludge cut by the slice is subjected to torsional force, causing the sludge extending out of the discharge cylinder to separate from the sludge inside the discharge cylinder. This prevents the sludge pushed out of the squeezing cylinder from sticking with the sludge that has not been pushed out of the squeezing cylinder, thus avoiding equipment blockage, ensuring the normal operation of the equipment, and improving the sludge treatment efficiency of the device.

[0016] 2. This invention uses columnar sludge extending from the discharge cylinder to push the mounting frame to move, which in turn drives the swing rod, which in turn drives the lifting rod. This causes the lifting frame to move the cleaning plate to scrape the sludge that has not detached from the device, thereby allowing the sludge that has undergone dewatering treatment to be discharged from the device. This prevents the sludge that has not detached from the device from clogging the device and improves the device's sludge treatment efficiency.

[0017] 3. The present invention gradually reduces the inner diameter of the compression cylinder, causing the water in the sludge inside the compression cylinder to be squeezed out. At the same time, the screw conveyor drives the compression cylinder to rotate by increasing the damping between the sludge and the compression cylinder, causing the sludge inside the compression cylinder to rotate synchronously. The centrifugal force of the rotating sludge further improves the water removal effect and water removal efficiency of the sludge. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A typical embodiment of the present invention, such as Figure 1 As shown, a reciprocating sludge extrusion drying device includes a frame 1, on which a feed cylinder 11, a dewatering component 2, and a cutting component 4 are provided. The feed cylinder 11 and the cutting component 4 are located at both ends of the dewatering component 2, respectively.

[0021] like Figure 2 and Figure 3 As shown, a spiral auger 12 is provided inside the feed cylinder 11. A compression section is provided on the spiral auger 12, and the diameter of the compression section of the spiral auger 12 gradually decreases. A feed hopper 13 is provided at the upper end of the feed cylinder 11, and the feed hopper 13 is connected to the feed cylinder 11. One end of the spiral auger 12 is rotatably connected to the frame 1. A motor 14 is fixedly installed on the side wall of the end of the frame 1 connected to the spiral auger 12. The output shaft of the motor 14 is coaxially connected to one end of the spiral auger 12.

[0022] In use, wet sludge is fed into the feed hopper 13, so that the wet sludge enters the feed cylinder 11 under the action of gravity. By starting the motor 14, the output shaft of the motor 14 drives the screw conveyor 12 to rotate, which in turn causes the screw conveyor 12 to push the wet sludge in the feed cylinder 11 along the pushing direction of the screw conveyor 12, thereby pushing the sludge into the dewatering component 2 to remove the flowing water in the wet sludge.

[0023] The water removal component 2 includes a compression cylinder 21, a filter cylinder 22, and a water collection tank 23. One end of the compression cylinder 21 is rotatably connected to and communicates with the feed cylinder 11, and the other end is rotatably connected to the water collection tank 23. A shaft seat 24 is fixedly installed at the end of the compression cylinder 21 away from the feed cylinder 11. The end of the spiral auger 12 away from the motor 14 is rotatably connected to the shaft seat 24. The filter cylinder 22 is sleeved on the outside of the compression cylinder 21 and is fixedly connected to the compression cylinder 21. The water collection tank 23 is located on the outside of the filter cylinder 22 and is rotatably connected to the filter cylinder 22. The water collection tank 23 is fixed on the frame 1, and an outlet 25 is provided at the lower end of the water collection tank 23.

[0024] The inner diameter of the compression cylinder 21 gradually decreases along the direction of sludge movement. The compression section of the auger 12 is located inside the compression cylinder 21. The auger 12 propels the sludge, causing the internal space of the compression cylinder 21 to gradually decrease as the sludge moves within it. This results in the sludge continuously accumulating and being compressed. At this time, the flowing water in the sludge will be squeezed out under pressure and pass through the through holes on the cylinder wall of the compression cylinder 21 into the filter cartridge 22. Simultaneously, due to the compression of the sludge within the compression cylinder 21, the damping between the sludge and the compression cylinder 21 increases, allowing the compression cylinder 21 and the filter cartridge 22 to pass through the sludge and the auger 12. The auger 12 operates synchronously. At this time, the flowing water in the sludge is squeezed out and subjected to centrifugal force. Centrifugal force can further improve the separation effect and efficiency of the flowing water in the sludge. Since the flowing water entering the filter cartridge 22 through the through hole carries mud and sand and a small amount of sludge, the water entering the filter cartridge 22 is turbid. The compression cylinder 21 drives the filter cartridge 22 to rotate synchronously, causing the water entering the filter cartridge 22 to be filtered twice by centrifugal force. At this time, the water splashed from the filter cartridge 22 under the action of centrifugal force will be collected through the water collection tank 23 and discharged from the outlet 25.

[0025] like Figures 4-7 As shown, the cutting component 4 includes a discharge cylinder 41. One end of the discharge cylinder 41 is fixedly connected to the water collection tank 23, and the discharge cylinder 41 is connected to the compression cylinder 21. A mounting bracket 42 is provided at the end of the discharge cylinder 41 away from the water collection tank 23. The mounting bracket 42 has a circular structure and a sealing plate 43 is provided inside the mounting bracket 42. The sealing plate 43 is rotatably connected to the mounting bracket 42. Mounting seats 413 are symmetrically provided at the end of the discharge cylinder 41 near the sealing plate 43. First guide rods 422 are provided on both sides of the mounting bracket 42. Both first guide rods 422 are parallel to the axis of the discharge cylinder 41. The two first guide rods 422 are correspondingly provided with the two mounting seats 413. The first guide rods 422 pass through the mounting seats 413 and are slidably connected to the mounting seats 413. The first guide rods 422 are located away from the mounting seats 413. A trigger block 421 is provided at one end, and a first spring 423 is sleeved on the outside of the first guide rod 422. The first spring 423 is located between the trigger block 421 and the mounting base 413. The first guide rod 422 is slidably connected to the mounting base 413, so that the first guide rod 422 supports and guides the mounting frame 42 and the sealing plate 43. In use, the sludge is pushed by the spiral auger 12 and enters the discharge cylinder 41 through the compression cylinder 21. At this time, the first spring 423 will apply a force to the sealing plate 43 to block the sludge. When the accumulation force of the sludge is greater than the elastic force of the first spring 423, the sludge will press the sealing plate 43. At this time, the first spring 423 will deform, so that the sealing plate 43 will gradually move away from the discharge cylinder 41. At this time, the sludge will be discharged from the outlet end of the discharge cylinder 41. like Figure 4 and Figure 8As shown, a telescopic cylinder 44 is installed inside the discharge cylinder 41. One end of the telescopic cylinder 44 is rotatably connected to the bearing seat 24. A top block 46 is installed inside the telescopic cylinder 44. The top block 46 is connected to the middle area of ​​the sealing plate 43 via a telescopic rod 45. A guide part is provided at the connection between the telescopic rod 45 and the top block 46 to ensure a smooth transition between the telescopic rod 45 and the top block 46. A telescopic groove 49 is provided on the side wall of the telescopic cylinder 44 away from the bearing seat 24. Multiple telescopic grooves 49 are provided and are symmetrically arranged. A slice 47 is placed inside the telescopic groove 49. The slice 47 is inclined towards the direction of sludge movement. An extension plate 50 is fixedly installed at the end of the slice 47 away from the discharge cylinder 41. A horizontal plate 64 is provided on one side wall of the extension plate 50, perpendicular to the extension plate 50. A first spring plate 65 is provided on the side of the horizontal plate 64 near the slice 47, and the other end of the first spring plate 65 is connected to the inner wall of the telescopic cylinder 44. A first roller 66 is rotatably provided on the end of the extension plate 50 away from the slice 47. Under the elastic force of the first spring plate 65, the first roller 66 will contact the telescopic rod 45. When the telescopic rod 45 moves the top block 46 to a certain position, the first roller 66 will slide along the guide part, and then the guide part and the top block 46 will push the slice 47 to slide out along the telescopic groove 49. At this time, the slice 47 will cut the interior of the columnar sludge. like Figure 6 and Figure 7 As shown, the cutting component 4 also includes symmetrically arranged insertion grooves 411 on the side wall of the discharge cylinder 41 near the end of the sealing plate 43. Insertion posts 412 are provided in the insertion grooves 411. A second spring piece 414 is provided on the outer wall of the discharge cylinder 41. One end of the second spring piece 414 is connected to the insertion post 412, and the other end is fixed to the outer wall of the discharge cylinder 41. The second spring piece 414 is bent, causing a gap between the end of the second spring piece 414 away from its connection to the discharge cylinder 41 and the side wall of the discharge cylinder 41. At this time, the end of the insertion post 412 inserted into the insertion groove 411 is tangential to the inner wall of the discharge cylinder 41. When the sludge presses the sealing plate 43 to move, the first... The guide rod 422 will drive the trigger block 421 to move to contact the second spring 414. Under the pressure of the trigger block 421, the second spring 414 moves towards the discharge cylinder 41. At this time, the second spring 414 will drive the plug post 412 to move along the plug groove 411 into the discharge cylinder 41. At this time, the slice 47 will cut the columnar sludge extending out of the discharge cylinder 41. The plug post 412 extends and blocks the sludge pushed in by the auger 12, increasing the resistance to the movement of the sludge in the discharge cylinder 41, thereby reducing the pressure of sludge accumulation on the slice 47, thus avoiding deformation of the slice 47 due to the pressure of sludge accumulation.

[0026] The sealing plate 43 is also provided with a twisting component 5, which can rotate the columnar sludge extending out of the discharge cylinder 41, thereby twisting the columnar sludge from the cut-off point.

[0027] like Figure 4 As shown, the twisting component 5 includes a plurality of clamping rods 48 arranged in an array on the side of the sealing plate 43 near the discharge cylinder 41. A rotating cylinder 431 is provided on the side of the sealing plate 43 away from the clamping rods 48. A movable cylinder 432 is sleeved on the outside of the rotating cylinder 431. Guide blocks 4311 are symmetrically arranged on the outside of the rotating cylinder 431. A spiral groove 4321 is on the inner wall of the movable cylinder 432. The guide block 4311 is slidably disposed in the spiral groove 4321.

[0028] A guide cylinder 433 is provided on the outer side of the movable cylinder 432. One end of the guide cylinder 433 is fixedly connected to the mounting bracket 42. Keyways 4333 are symmetrically provided on the inner wall of the guide cylinder 433. The extension direction of the keyways 4333 is parallel to the axis of the guide cylinder 433. Guide posts 4322 are symmetrically provided on the outer wall of the movable cylinder 432. The guide posts 4322 are slidably installed in the keyways 4333.

[0029] A first plug 4331 is provided at the end of the guide cylinder 433 away from the mounting bracket 42. The axis of the first plug 4331 coincides with the axis of the guide cylinder 433. A first piston 4332 is slidably connected inside the first plug 4331. The first piston 4332 is connected to the middle area of ​​the end of the moving cylinder 432 away from the sealing plate 43 through the connecting rod 4334. The connecting rod 4334 passes through the bottom surface of the guide cylinder 433 and is slidably connected to the bottom surface of the guide cylinder 433.

[0030] A third spring (not shown in the figure) is connected between the bottom of the first piston 4332 and the first plug cylinder 4331. When the first piston 4332 moves inside the first plug cylinder 4331, the moving cylinder 432 will move synchronously with the first piston 4332. The keyway 4333 guides the movement of the moving cylinder 432, so that the guide block 4311 slides along the spiral groove 4321 during the movement of the moving cylinder 432, which is used to make the rotating cylinder 431 drive the sealing plate 43 to rotate.

[0031] like Figure 9 and Figure 10 As shown, the twisting component 5 also includes a second plug cylinder 51. There are two second plug cylinders 51, both of which are fixed on the frame 1 and located on both sides of the first plug cylinder 4331. A second piston 52 is slidably connected inside the second plug cylinder 51. A push rod 53 is provided on one side of the second piston 52. The push rod 53 is perpendicular to the second piston 52. The end of the push rod 53 away from the second piston 52 passes through the top surface of the second plug cylinder 51 and is slidably connected to the top surface of the second plug cylinder 51. A push rod 54 is provided on the side of the second piston 52 away from the push rod 53. The axis of the push rod 54 coincides with the axis of the second piston 52.

[0032] The bottom of the second plug cylinder 51 is provided with an exhaust groove 55, which is frustoconical in shape. A movable column 56 is slidably connected inside the exhaust groove 55. A vent hole is opened at the axis of the movable column 56, and a one-way valve 57 is installed in the vent hole. The end of the push rod 54 is positioned directly opposite the vent hole. A plug 58 is provided at one end of the movable column 56. The vent hole passes through the movable column 56 and the plug 58. The plug 58 is adapted to the exhaust groove 55. A limit plate 59 is provided at the end of the movable column 56 away from the plug 58. A second spring 60 is sleeved on the outside. One end of the second spring 60 is connected to the limiting plate 59, and the other end is connected to the bottom of the second plug cylinder 51. A sealing plate 61 is provided at the end of the plug 58 away from the moving column 56. A sealing ring is provided on the side of the sealing plate 61 near the plug 58. A movable cavity 62 is also provided on the second plug cylinder 51. The movable cavity 62 is located on the outside of the bottom of the second plug cylinder 51. The sealing plate 61 is located inside the movable cavity 62. The bottom of the movable cavity 62 is connected to the first plug cylinder 4331 through an air pipe 63.

[0033] In use, when the sealing plate 43 moves the mounting bracket 42 to its limit position, the mounting bracket 42 contacts the push rod 53 and pushes the push rod 53, causing the second piston 52 to move inside the second plug cylinder 51. At this time, the air pressure inside the second plug cylinder 51 increases. As the second piston 52 moves, the push rod 54 pushes the moving column 56, causing the second spring 60 to deform and compress. The plug 58 separates from the exhaust groove 55, and the air pressure inside the second plug cylinder 51 is discharged through the exhaust groove 55. Then, it is introduced into the first plug cylinder 4331 through the air pipe 63. At this time, the gas pressure inside the first plug cylinder 4331 increases, causing the first piston 4332 to move inside the first plug cylinder 4331. The first piston 4332 drives the moving cylinder 432 towards the first plug cylinder 4331 via the connecting rod 4334. The moving cylinder 432 moves away from the sealing plate 43, and the guide cylinder 433 guides the displacement of the moving cylinder 432. The keyway 4333 limits the movement of the guide column 4322. The guide block 4311 on the outside of the rotating cylinder 431 slides in the spiral groove 4321 inside the moving cylinder 432, causing the rotating cylinder 431 to rotate, thereby driving the sealing plate 43 to rotate in the mounting frame 42. Since the sludge wraps around the clamping rod 48 during the accumulation process, when the sealing plate 43 rotates, the sealing plate 43 will drive the columnar sludge extending out of the discharge cylinder 41 to rotate through the clamping rod 48. This causes the columnar sludge to be torn at the cut point of the slice 47, thereby causing the sludge extending out of the discharge cylinder 41 to break and separate from the sludge not extending out of the discharge cylinder 41.

[0034] During this process, the end of the push rod 54 away from the second piston 52 blocks the vent hole of the one-way valve 57, so that the gas introduced into the first plug cylinder 4331 will not flow back to the second plug cylinder 51 through the one-way valve 57.

[0035] A cleaning component 3 is provided below the discharge cylinder 41, such as... Figure 11 and Figure 12 As shown, the cleaning component 3 includes a lifting frame 31. Second guide rods 35 are fixedly installed at the four corners of the lifting frame 31. The end of the second guide rod 35 away from the lifting frame 31 passes through the frame 1. A third spring 36 is sleeved on the outside of the second guide rod 35. One end of the third spring 36 is connected to the end of the second guide rod 35 away from the lifting frame 31, and the other end of the third spring 36 is connected to the frame 1.

[0036] A cleaning plate 32 is provided on the upper surface of the lifting frame 31. The cleaning plate 32 is perpendicular to the lifting frame 31, and the end of the cleaning plate 32 away from the lifting frame 31 has a comb-like structure.

[0037] The cleaning component 3 also includes a swing rod 33, one end of which is connected to a lifting rod 34. The lifting rod 34 is located at the lower end of the lifting frame 31. The swing rod 33 and the lifting rod 34 are vertically connected. The connection between the swing rod 33 and the lifting rod 34 is hinged to the frame 1. A connecting block 37 is hinged to the end of the lifting rod 34 away from the swing rod 33. A sliding groove 38 is provided on the bottom surface of the lifting frame 31. The extension direction of the sliding groove 38 is the same as the movement direction of the sludge. The connecting block 37 is slidably disposed in the sliding groove 38.

[0038] During the process of the sealing plate 43 driving the mounting frame 42 to move to the limit position, the mounting frame 42 contacts the swing rod 33 and pushes the swing rod 33 to rotate around the hinge point with the frame 1. The lifting rod 34 lifts the lifting frame 31 upward under the drive of the swing rod 33, so that the cleaning plate 32 is inserted into the columnar sludge. When the twisting component 5 drives the columnar sludge to rotate, the cleaning plate 32 will be scraped by the columnar sludge discharged from the discharge cylinder 41, thereby peeling off the sludge attached to the outside of the telescopic rod 45.

[0039] Finally, the sealing plate 43 will be reset under the elastic force of the first spring 423. Then, the mounting bracket 42 will no longer push the push rod 53, the plug 58 will block the exhaust groove 55, and the third spring will push the first piston 4332 to reset, thereby causing the air pressure in the first plug cylinder 4331 to flow back.
