Sludge dewatering device with self-cleaning function

Abstract

This utility model discloses a sludge dewatering device with self-cleaning function, including: a support structure, the outer wall of which is fixedly connected to a conveying device, and a cleaning device, the outer wall of which is slidably connected to the inner wall of the support structure. This utility model relates to the field of sludge dewatering technology. The cleaning device and the support structure are connected by a conveying device. The drive gear in the conveying device drives the connecting gear to rotate, which in turn drives the rotating rod to rotate. The rotating rod then drives the toothed disc of the cleaning device to rotate through the connecting gear, ultimately causing the scraper to slide along the outer wall of the filter cylinder and scrape off the attached sludge, preventing the sludge from clogging the filter cylinder. The screw rod, driven by a motor, can stably and continuously convey the sludge in the feed hopper to the filter cylinder. At the same time, the extrusion plate in the support structure, under the action of a pressure spring, applies continuous extrusion force to the sludge in the filter cylinder, so that the water in the sludge can quickly and effectively seep out of the filter cylinder into the collection frame.

Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, specifically to a sludge dewatering device with self-cleaning function. Background Technology

[0002] With the continuous expansion of industrial production scale and the acceleration of urbanization, the amount of sewage generated has continued to rise, and the output of sludge has also increased dramatically. Sludge contains a large amount of water, and if it is not effectively dewatered, it will not only occupy a lot of storage space, but may also cause serious pollution to the environment.

[0003] In existing technologies, common sludge dewatering equipment is prone to filter cartridge clogging during the dewatering process. Due to the complex composition of sludge, fine sludge particles easily seep out and adhere to the outer wall of the filter cartridge during dewatering, especially in the top area where gravity is relatively weak, making it difficult for the sludge to detach on its own. Filter cartridge clogging not only severely affects filtration performance and reduces dewatering efficiency but may also lead to frequent equipment shutdowns, requiring manual cleaning and maintenance. This not only increases labor costs but also reduces the operational stability and lifespan of the equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sludge dewatering device with a self-cleaning function, which solves the problem that the filter cartridge is prone to clogging during the dewatering process.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sludge dewatering device with self-cleaning function includes: a supporting structure, a conveying device fixedly connected to the outer wall of the supporting structure, and a cleaning device, the outer wall of the cleaning device being slidably connected to the inner wall of the supporting structure; the conveying device includes a base, a motor fixedly connected to the outer wall of the top of the base, a screw rod fixedly connected to the outer wall of the motor, a drive gear fixedly connected to the outer wall of the motor, a feed hopper slidably connected to the outer wall of the screw rod, a support block fixedly connected to the outer wall of the top of the base, a rotating rod rotatably connected to the inner wall of the support block, and connecting gears symmetrically fixedly connected to the outer wall of the rotating rod.

[0009] Preferably, the outer wall of the helical rod is fixedly connected to the outer wall of the upper shaft of the motor. The upper shaft of the motor drives the helical rod fixedly connected to it to rotate. The drive gear is fixedly connected to the side of the upper shaft of the motor. The outer wall of the connecting gear meshes with the outer wall of the drive gear. When the drive gear rotates, it will drive the connecting gear to rotate.

[0010] Preferably, the support structure includes a collection frame, a filter cylinder is fixedly connected to the inner wall of the collection frame, rotating grooves are symmetrically opened on the inner wall of the side of the collection frame, a slide rod is fixedly connected to the outer wall of the collection frame, a pressing plate is slidably connected to the outer wall of the slide rod, a pressure spring is fixedly connected to the outer wall of the pressing plate, and a baffle is fixedly connected to the outer wall of the slide rod.

[0011] Preferably, the rotating groove is located at both ends of the filter cylinder, the outer wall of the pressure spring on the side away from the extrusion plate is fixedly connected to the outer wall of the baffle, the outer wall of the collection frame on the side away from the extrusion plate is fixedly connected to the outer wall of the feed hopper, the inner wall of the collection frame is rotatably connected to the outer wall of the rotating rod, the outer wall of the collection frame is fixedly connected to the outer wall of the base, and the inner wall of the filter cylinder is slidably connected to the outer wall of the screw rod. Since the feed hopper and the screw rod are slidably connected, the screw rod will transport the sludge in the feed hopper along the spiral trajectory of the screw rod to the filter cylinder in the support structure during rotation.

[0012] Preferably, the cleaning device includes a connecting rod, a scraper is fixedly connected to the outer wall of the connecting rod, a toothed disc is fixedly connected to the outer wall of the side of the connecting rod, and a turntable is fixedly connected to the outer wall of the connecting rod away from the toothed disc.

[0013] Preferably, the outer walls of the turntable and the toothed disc are slidably connected to the inner wall of the rotating groove, the outer wall of the scraper is slidably connected to the outer wall of the filter cartridge, and the outer wall of the toothed disc meshes with the connecting gear. During the rotation of the rotating rod, since the connecting gear on the other side meshes with the toothed disc in the cleaning device, the rotation of the connecting gear will drive the toothed disc to rotate. Both the toothed disc and the turntable are slidably connected to the rotating groove opened on the inner wall of the side of the collection frame. Therefore, when the toothed disc rotates, it will drive the connecting rod to make a circular motion around the rotating groove. With the circular motion of the connecting rod, the scraper will slide along the outer wall of the filter cartridge.

[0014] (III) Beneficial Effects

[0015] This invention provides a sludge dewatering device with a self-cleaning function. It has the following beneficial effects:

[0016] (i) This cleaning device solves the common problem of filter cartridge clogging by driving gears. During the sludge dewatering process, some fine sludge tends to adhere to the outer wall of the filter cartridge, especially the sludge at the top of the filter cartridge, which is difficult to fall off by gravity. The driving gear in the conveying device drives the connecting gear to rotate, which in turn drives the rotating rod to rotate. The rotating rod then drives the toothed disc of the cleaning device to rotate through the connecting gear, which in turn causes the scraper to slide along the outer wall of the filter cartridge and scrape off the attached sludge, thus preventing sludge from clogging the filter cartridge and ensuring the filtration performance of the filter cartridge. This maintains the long-term stable operation of the equipment and reduces the workload of manual cleaning and equipment maintenance costs.

[0017] (ii) The support structure achieves sludge dewatering through the extrusion plate. Driven by the motor, the screw can stably and continuously transport the sludge in the feed hopper to the filter cartridge. At the same time, the extrusion plate in the support structure, under the action of the pressure spring, applies continuous extrusion force to the sludge in the filter cartridge, so that the water in the sludge can quickly and effectively seep out of the filter cartridge into the collection frame, ensuring the smooth progress of the dewatering work.

[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] Please see Figure 1-5 This utility model provides a technical solution: a sludge dewatering device with self-cleaning function, including: a support structure 1, a conveying device 2 fixedly connected to the outer wall of the support structure 1, and a cleaning device 3, the outer wall of the cleaning device 3 being slidably connected to the inner wall of the support structure 1; the conveying device 2 includes a base 21, a motor 22 fixedly connected to the outer wall of the top of the base 21, a screw rod 23 fixedly connected to the outer wall of the motor 22, a drive gear 24 fixedly connected to the outer wall of the motor 22, a feed hopper 25 slidably connected to the outer wall of the screw rod 23, a support block 26 fixedly connected to the outer wall of the top of the base 21, a rotating rod 27 rotatably connected to the inner wall of the support block 26, and connecting gears 28 symmetrically fixedly connected to the outer wall of the rotating rod 27.

[0026] The outer wall of the screw rod 23 is fixedly connected to the outer wall of the shaft on the motor 22. The shaft of the motor 22 drives the screw rod 23, which is fixedly connected to it, to rotate. The drive gear 24 is fixedly connected to the side of the shaft on the motor 22. The outer wall of the connecting gear 28 meshes with the outer wall of the drive gear 24. When the drive gear 24 rotates, it will drive the connecting gear 28 to rotate.

[0027] The support structure 1 includes a collection frame 11, a filter cylinder 12 is fixedly connected to the inner wall of the collection frame 11, rotating grooves 13 are symmetrically opened on the inner wall of the side of the collection frame 11, a slide rod 14 is fixedly connected to the outer wall of the collection frame 11, a pressing plate 15 is slidably connected to the outer wall of the slide rod 14, a pressure spring 16 is fixedly connected to the outer wall of the pressing plate 15, and a baffle 17 is fixedly connected to the outer wall of the slide rod 14.

[0028] The rotating trough 13 is set at both ends of the filter cylinder 12. The outer wall of the pressure spring 16 away from the extrusion plate 15 is fixedly connected to the outer wall of the baffle 17. The outer wall of the collection frame 11 away from the extrusion plate 15 is fixedly connected to the outer wall of the feed hopper 25. The inner wall of the collection frame 11 is rotatably connected to the outer wall of the rotating rod 27. The outer wall of the collection frame 11 is fixedly connected to the outer wall of the base 21. The inner wall of the filter cylinder 12 is slidably connected to the outer wall of the screw rod 23. Since the feed hopper 25 is slidably connected to the screw rod 23, the screw rod 23 will transport the sludge in the feed hopper 25 along the spiral trajectory of the screw rod 23 to the filter cylinder 12 in the support structure 1 during rotation.

[0029] The cleaning device 3 includes a connecting rod 31, a scraper 32 is fixedly connected to the outer wall of the connecting rod 31, a toothed disc 33 is fixedly connected to the outer wall of the side of the connecting rod 31, and a turntable 34 is fixedly connected to the outer wall of the connecting rod 31 on the side away from the toothed disc 33.

[0030] The outer walls of the turntable 34 and the toothed disc 33 are slidably connected to the inner wall of the rotating groove 13. The outer wall of the scraper 32 is slidably connected to the outer wall of the filter cylinder 12. The outer wall of the toothed disc 33 is meshed with the connecting gear 28. During the rotation of the rotating rod 27, since the connecting gear 28 on the other side is meshed with the toothed disc 33 in the cleaning device 3, the rotation of the connecting gear 28 will drive the toothed disc 33 to rotate. Both the toothed disc 33 and the turntable 34 are slidably connected to the rotating groove 13 opened on the inner wall of the side of the collection frame 11. Therefore, when the toothed disc 33 rotates, it will drive the connecting rod 31 to make a circular motion around the rotating groove 13. With the circular motion of the connecting rod 31, the scraper 32 will slide along the outer wall of the filter cylinder 12.

[0031] When in use, start the conveying device 2 and feed the sludge that needs to be dewatered into the screw rod 23 through the feed hopper 25. Through the cooperation of the support structure 1 and the screw rod 23, the water in the sludge seeps out from the filter cylinder 12 into the collection frame 11, thereby achieving sludge dewatering. At the same time, during the dewatering process, the conveying device 2 will drive the cleaning device 3 to clean the outer wall of the filter cylinder 12 through the connecting gear 28.

[0032] When the equipment is started, the conveying device 2 starts working, the motor 22 on the base 21 starts, and the rotating shaft of the motor 22 drives the screw rod 23 fixedly connected to it to rotate. Since the feed hopper 25 is slidably connected to the screw rod 23, the screw rod 23 will transport the sludge in the feed hopper 25 along the spiral trajectory of the screw rod 23 to the filter cylinder 12 in the support structure 1 during the rotation. Since the slide rod 14 is fitted with a squeezing plate 15, and a pressure spring 16 is connected between the squeezing plate 15 and the baffle 17, after the sludge continuously enters the filter cylinder 12, the sludge will push the squeezing plate 15 to slide outward along the slide rod 14, but the elastic force of the pressure spring 16 will have a reaction force, thereby squeezing the sludge in the filter cylinder 12. During the squeezing process, the water in the sludge will seep out from the filter cylinder 12 into the collection frame 11 through the filtration effect of the filter cylinder 12, thereby achieving the dewatering of the sludge. The dewatered sludge will be squeezed out through the gap on the side of the collection frame 11 near the squeezing plate 15.

[0033] During the dehydration process, some fine mud may seep out through the filter cartridge 12, especially at the top of the filter cartridge 12. The mud cannot fall off due to gravity and will adhere to the outer wall of the filter cartridge 12. In this case, the cleaning device 3 is needed. The drive gear 24 on the side of the motor 22 shaft will rotate with the shaft. The drive gear 24 meshes with the connecting gear 28 symmetrically fixedly connected to the rotating rod 27. When the drive gear 24 rotates, it drives the connecting gear 28 to rotate, thereby causing the rotating rod 27 to rotate within the support block 26 and the collection frame 11. As the rotating rod 27 rotates... During the process, since the connecting gear 28 on the other side meshes with the toothed disc 33 in the cleaning device 3, the rotation of the connecting gear 28 will drive the toothed disc 33 to rotate. Both the toothed disc 33 and the turntable 34 are slidably connected to the rotating groove 13 opened on the inner wall of the side of the collection frame 11. Therefore, when the toothed disc 33 rotates, it will drive the connecting rod 31 to make a circular motion around the rotating groove 13. As the connecting rod 31 moves in a circular motion, the scraper 32 will slide along the outer wall of the filter cartridge 12 and scrape off the sludge attached to the outer wall of the filter cartridge 12, thereby realizing the self-cleaning function of the filter cartridge 12 and avoiding sludge clogging the filter cartridge 12 and affecting the dewatering effect.
