Description

Technical Field

[0001] This invention relates to the field of bar screen cleaning machine technology, specifically a rotary filter type bar screen cleaning machine. Background Technology

[0002] The bar screen cleaner is a specialized water treatment device that can continuously and automatically intercept and remove debris of various shapes from fluids. It can be widely used in urban sewage treatment, tap water industry, and power plant inlets. It can also be used as a pre-screening device in wastewater treatment processes in industries such as textiles, food processing, papermaking, and leather. It is one of the most advanced solid-liquid screening devices in my country.

[0003] According to Chinese Patent No. CN107854894B, a rotary bar screen cleaning machine includes: a transmission chain, a guide hood, a cleaning assembly, several filter screens, and several mounting assemblies. Each mounting assembly includes: a rotating component, a rotating base, and a coil spring. The rotating base is fixedly mounted on the transmission chain. A rotating component that can rotate relative to the rotating base is inserted into the rotating base. The rotating component is mounted on the filter screen and cannot rotate relative to the filter screen. The inner end of the coil spring can remain stationary relative to the rotating base, and the outer end of the coil spring can remain stationary relative to the rotating component. Under the action of the coil spring, the filter screen can be kept perpendicular to the transmission chain segment. A guide hood is installed below the transmission chain. The cleaning assembly is installed at the top inlet of the guide hood and includes a mounting frame, a rotating roller, and brush bristles.

[0004] In summary, the shortcomings of the existing technology are that although it can ensure the clean brush head at the end of the transmission chain and prevent obstruction of the filter, it is difficult to clean tangled parts such as hair, which can easily lead to internal blockage. Therefore, there is still room for improvement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is as follows: A rotary screen bar screen cleaning machine specifically includes: The machine base has a straightening device embedded in the middle of its top. This straightening device is used to adjust the internal structure of the equipment. A cleaning device is movably installed at the top of the straightening device. This cleaning device is used to adjust the state of dust collection and straightening. A cover plate is fixedly installed between the cleaning device and the straightening device. A chain device is driven in the inner cavity of the straightening device. This chain device is used to adjust the transmission state during rotation. The chain device includes a first disc body. The rotation of the central shaft drives the first disc body to move synchronously. The inner cavity of the first disc body moves synchronously. The transmission chain is wound around the outer surface of the first disc body. The central shaft is movably installed at the axis of the first disc body. The transmission chain is driven and installed on the outer surface of the first disc body. The inner sidewall of the transmission chain is embedded with a toothed rake. There are two first disc bodies in total, and a through plate is fixedly installed between the two first disc bodies. An anti-jamming device is driven and installed at the top of the transmission chain. A through shaft is movably inserted into the axis of the anti-jamming device.

[0006] Furthermore, the first disc is connected to the anti-jamming device via a transmission chain. The diameters of the through shaft and the central shaft are the same. The through plate has an arc-shaped structure. The anti-jamming device also includes a second disc. A cylindrical component is provided on the side of the second disc away from the transmission chain. A block is fixedly installed on the top of the inner wall of the cylindrical component. There are two blocks, and a plate is movably installed between the two blocks. A main rod is rotatably installed on the bottom of the inner wall of the cylindrical component. An anti-jamming body is fixedly connected to the top of the main rod. The plate is arc-shaped. The centers of the second disc and the cylindrical component are on the same straight line. The anti-jamming body has an irregular shape. When the anti-jamming body swings upward, the toothed rake moves along the upper part of the anti-jamming body to the top. The block cooperates with the plate to block the toothed rake. The main rod is movably embedded in the middle of the inner part of the cylindrical component. The plate is made of stainless steel. The cylindrical component is symmetrically designed about the center line of the plate. The block has a slot corresponding to the plate inside.

[0007] Furthermore, the plate also includes a thin plate that moves by impacting the upright frame. The shaft supports the thin plate, and the upright frame moves in conjunction with the sieve layer, causing the sieve layer to vibrate up and down. The sieve layer separates dirt and impurities, and the solid and liquid components are separated after sieving. The upright frame is movably installed at the bottom of the thin plate, and the sieve layer is fixedly connected to the bottom of the upright frame. The shaft is movably engaged on the side of the thin plate away from the through shaft, and a collecting device is fixedly connected to the top of the shaft. A middle arc seat is movably installed at the bottom of the sieve layer, and a seat body is fixedly connected to the bottom of the middle arc seat. The shaft body has a slot corresponding to the collecting device inside, and the middle arc seat has a hollow internal structure. The middle arc seat is located in the center of the seat body.

[0008] Furthermore, the tidying device includes a frame, with a base fixedly connected to the bottom of the frame's inner cavity. A first sliding cover is fixedly inserted into the top side of the base. A mounting plate is slidably installed in the inner cavity of the first sliding cover. A second sliding cover is fixedly installed in the inner cavity of the first sliding cover, away from the mounting plate. A push-pull plate is slidably installed inside the second sliding cover. The mounting plate tends to slide upwards along the inner wall of the first sliding cover. A hook is provided between the push-pull plate and the mounting plate. When the mounting plate slides to the top, it drags the push-pull plate to move synchronously. The push-pull plate slides along the inner groove of the second sliding cover. Through the cooperation of the mounting plate and the push-pull plate, the wiping strips on the mounting plate and the push-pull plate gradually scrape the hair and other debris inside. The bottom end of the mounting plate is connected to the push-pull plate. A buckle is provided between the mounting plate and the push-pull plate. Wiping strips are provided on both sides of the mounting plate. The mounting plate and the push-pull plate have the same specifications and dimensions.

[0009] This invention provides a rotary screen bar screen cleaning machine. It has the following advantages: 1. This rotary screen bar screen cleaner rotates against the direction of water flow via a drive chain. When the drive chain reaches the upper part of the equipment, the guide wheels and curved rails cause a relative self-cleaning motion between each set of drive chains. Most of the solid dirt falls off due to gravity, while the other part is cleaned by the reverse motion of the sweeper, removing the debris stuck to the rake. The drive chain in the direction of water flow is similar to a bar screen. After the rake separates the solid suspended matter in the fluid, it ensures smooth water flow. The entire working process can be continuous or intermittent.

[0010] 2. This rotary screen bar screen cleaner uses a central shaft to rotate, which drives the first disc to move synchronously. The inner cavity of the first disc moves synchronously, and the transmission chain is wound around the outer surface of the first disc. The transmission chain tends to rotate and rotate as it moves. When the transmission chain moves, it drives the toothed rake to move. As the toothed rake moves, it gradually cleans the dirty parts inside the frame, thereby ensuring the cleanliness of the equipment.

[0011] 3. This rotary screen bar screen cleaning machine features a mounting plate that slides upwards along the inner wall of the first sliding cover. A hook is installed between the push-pull plate and the mounting plate. When the mounting plate slides to its top, it drags the push-pull plate, which then slides along the inner groove of the second sliding cover. Through the combined use of the mounting plate and the push-pull plate, the wiping strips on both plates gradually scrape away hair and other debris, reducing hair growth on the inner wall of the frame. Continuous wiping causes hair and dirt to gradually fall into the gaps of the mounting plate, ensuring the equipment has a rapid hair-cleaning function and minimizing the interference of hair on the inner wall of the frame.

[0012] 4. This rotary screen bar screen cleaner, through the movement of the rake components towards the second disc, with the shaft rotating along with the second disc, tends to contact the anti-jamming body. The anti-jamming body is squeezed and deformed with reference to the main rod, causing it to twist from bottom to top. In addition, the cylindrical component itself has a certain inclined groove on its side. When the anti-jamming body swings to the top, the rake components move along the upper part of the anti-jamming body to the top. The block and plate components block the rake components, preventing them from falling due to sudden weightlessness. This ensures that the equipment can quickly and normally pass through corners and maintain the function of rotary screen operation, avoiding jamming. Compared with existing technologies, this reduces unnecessary operation steps and improves the balance of transportation.

[0013] 5. This rotary screen bar screen cleaner works by having dirt accumulated above the toothed rakes gradually fall onto the top of the fine plate. The fine plate is squeezed downwards and displaced, impacting the upright frame and moving. The shaft supports the fine plate, and the upright frame moves in conjunction with the screen layers, causing the screen layers to vibrate up and down. The screen layers separate dirt and impurities, isolating the solid and liquid components. Solid particles remain at the top, while smaller particles or water droplets fall from inside the central arc seat to the base. A corresponding cylinder is placed at the bottom of the base to collect the water, thus ensuring rapid collection, internal dry and wet separation, and improved cleaning efficiency.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Examples of the invention are given for illustrative and descriptive purposes only and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] Example 1: Please refer to Figures 1-6 This invention provides a technical solution: a rotary screen bar screen cleaning machine, specifically comprising: The base 1 has a straightening device 2 embedded in the middle of its top, which is used to adjust the internal parts of the equipment. The straightening device 2 includes a frame 21. A receiving seat 23 is fixedly connected to the bottom of the inner cavity of the frame 21. A first sliding cover 22 is fixedly inserted into the top side of the receiving seat 23. A mounting plate 24 is slidably installed in the inner cavity of the first sliding cover 22. A second sliding cover 26 is fixedly installed in the inner cavity of the first sliding cover 22, away from the mounting plate 24. A push-pull plate 25 is slidably installed inside the second sliding cover 26. The mounting plate 24 tends to slide upward along the inner wall of the first sliding cover 22. A space is provided between the push-pull plate 25 and the mounting plate 24. When the mounting plate 24 slides to the top, it drags the push-pull plate 25 to move synchronously. The push-pull plate 25 slides along the inner groove of the second sliding cover 26. Through the cooperation of the mounting plate 24 and the push-pull plate 25, the wiping strips on the mounting plate 24 and the push-pull plate 25 are used to gradually scrape the hair and other debris inside. The bottom end of the mounting plate 24 is connected to the push-pull plate 25. A buckle is provided between the mounting plate 24 and the push-pull plate 25. Wiping strips are provided on both sides of the mounting plate 24. The mounting plate 24 and the push-pull plate 25 have the same specifications and dimensions.

[0018] When hair processing is required, the inner wall of the frame 21 contains a servo motor. One end of the central shaft 53 extends through the inner wall of the frame 21. The central shaft 53 meshes with the gear at the output end of the servo motor on the frame 21. When the central shaft 53 is activated, it rotates counterclockwise. As the central shaft 53 rotates, it gradually drives the through plate 54 to move. The rotating through plate 54 gradually wipes the mounting plate 24. The mounting plate 24 tends to slide upward along the inner wall of the first sliding cover 22. A locking mechanism is provided between the push-pull plate 25 and the mounting plate 24. When the mounting plate 24 slides to the top, it drags the push-pull plate 25 to move synchronously. The push-pull plate 25 slides along the inner groove of the second sliding cover 26. Through the cooperation of the mounting plate 24 and the push-pull plate 25, the wiping strips on the mounting plate 24 and the push-pull plate 25 gradually scrape the hair inside, reducing the hair growth on the inner wall of the frame 21. After continuous rubbing, the hair and dirt gradually fall into the gap of the mounting plate 24, thereby ensuring that the equipment has the function of quickly cleaning hair and reducing the interference of hair on the inner wall of the frame 21.

[0019] Example 2: Please refer to Figure 1 , Figure 2 , Figures 12-14 The present invention provides a technical solution: a cleaning device 3 is movably installed on the top of the tidying device 2, which is used to adjust the state of the surrounding dust collection and tidying. Plate 574 also includes a fine plate 33, which moves by impacting the upright frame 34. The shaft 32 supports the fine plate 33. The upright frame 34 moves in conjunction with the sieve layer 35, causing the sieve layer 35 to vibrate up and down. The sieve layer 35 screens dirt and impurities, and the solid and liquid after screening are separated. The upright frame 34 is movably installed at the bottom of the fine plate 33, and the sieve layer 35 is fixedly connected to the bottom of the upright frame 34. The shaft 32 is movably engaged on the side of the fine plate 33 away from the through shaft 56. The collecting device 31 is fixedly connected to the top of the shaft 32. The middle arc seat 37 is movably installed at the bottom of the sieve layer 35, and the seat body 36 is fixedly connected to the bottom of the middle arc seat 37. The shaft 32 has a slot corresponding to the collecting device 31 inside. The middle arc seat 37 has a hollow internal structure and is located in the middle of the seat body 36.

[0020] When dirt and impurities are transported to the top and need to be collected, the transmission chain 51, driven by the motor reducer, moves and drives the toothed rake 55. After the toothed rake 55 moves to the top, it squeezes the fine plate 33. The dirt accumulated above the toothed rake 55 gradually falls onto the top of the fine plate 33, which is then squeezed downwards and moved. The fine plate 33 hits the upright frame 34 and moves. The shaft 32 supports the fine plate 33, and the upright frame 34 moves in conjunction with the screen layer 35. The screen layer 35 vibrates up and down, and the dirt and impurities are screened inside the screen layer 35. The solid and liquid are separated after screening. Solid particles remain at the top, while smaller particles or water particles fall from the middle arc seat 37 to the seat body 36. A corresponding cylinder is placed at the bottom of the seat body 36 to hold the water, thus ensuring that the equipment can collect quickly, ensuring the separation of dry and wet materials inside, and improving the cleaning effect.

[0021] Example 3: Please refer to Figures 1-14 The present invention provides a technical solution: based on embodiment 1, a cover plate 4 is fixedly installed between the cleaning device 3 and the straightening device 2, and a chain device 5 is installed in the inner cavity of the straightening device 2 for transmission. The chain device 5 is used to adjust the transmission state during rotation. The chain device 5 includes a first disc body 52. ​​The central shaft 53 rotates and drives the first disc body 52 to move synchronously. The inner cavity of the first disc body 52 moves synchronously. The transmission chain 51 is wound around the outer surface of the first disc body 52. ​​The central shaft 53 is movably installed at the axis of the first disc body 52. ​​The transmission chain 51 is driven and installed on the outer surface of the first disc body 52. ​​The toothed rake 55 is embedded in the inner side wall of the transmission chain 51. There are two first disc bodies 52 in total, and a through plate 54 is fixedly installed between the two first disc bodies 52. An anti-jamming device 57 is driven and installed on the top of the transmission chain 51. A through shaft 56 is movably inserted into the axis of the anti-jamming device 57.

[0022] The first disc 52 is connected to the anti-jamming device 57 via a transmission chain 51. The diameters of the through shaft 56 and the central shaft 53 are the same. The through plate 54 has an arc-shaped structure. The anti-jamming device 57 also includes a second disc 571. A cylindrical component 572 is provided on the side of the second disc 571 away from the transmission chain 51. A block 573 is fixedly installed on the top of the inner wall of the cylindrical component 572. There are two blocks 573, and a plate 574 is movably installed between the two blocks 573. A main rod 575 is rotatably installed on the bottom of the inner wall of the cylindrical component 572. An anti-jamming body 5 is fixedly connected to the top of the main rod 575. 76. Plate 574 is arc-shaped. The centers of the second disc 571 and the cylindrical part 572 are on the same straight line. The anti-jamming body 576 is an irregularly shaped structure. When the anti-jamming body 576 swings to the top, the toothed rake 55 moves along the upper part of the anti-jamming body 576 to the top. The block 573 cooperates with plate 574 to block the toothed rake 55. The main rod 575 is movably embedded in the middle of the inner part of the cylindrical part 572. Plate 574 is made of stainless steel. The cylindrical part 572 is symmetrically designed about the center line of plate 574. The block 573 has a slot inside that corresponds to plate 574.

[0023] In use, the bar screen cleaner works primarily by assembling a unique set of toothed rakes 55 into a rotating transmission chain 51. Driven by a motor reducer, the transmission chain 51 rotates against the direction of water flow. When the transmission chain 51 reaches the top of the equipment, the guide wheel and curved rail cause a relative self-cleaning motion between each set of transmission chains 51. Most of the solid dirt falls off due to gravity, while the other part is cleaned by the reverse motion of the cleaner, removing the debris stuck to the toothed rakes 55. The transmission chain 51 in the direction of water flow is similar to a bar screen. After the toothed rakes 55 separate the solid suspended matter in the fluid, the water can flow smoothly. The entire working process can be continuous or intermittent.

[0024] When cleaning is required, the inner wall of the frame 21 contains a servo motor. One end of the central shaft 53 extends through the inner wall of the frame 21. The central shaft 53 meshes with the gear at the output end of the servo motor on the frame 21. When the central shaft 53 is activated, it rotates counterclockwise. The rotation of the central shaft 53 drives the first disc 52 to move synchronously. The middle part of the inner cavity of the first disc 52 moves synchronously. The transmission chain 51 is wrapped around the outer surface of the first disc 52. The transmission chain 51 tends to rotate and revolve. When the transmission chain 51 moves, it drives the toothed rake 55 to move accordingly. As the toothed rake 55 moves, it gradually cleans the dirty parts inside the frame 21, thereby ensuring the cleanliness of the equipment.

[0025] Because jamming is likely to occur when conveying to a corner, the toothed rake 55 gradually rises under the driving force of the central shaft 53. The plate 574 first contacts the collecting device 31, and then the toothed rake 55 is displaced to the top by the force of the central shaft 53. The toothed rake 55 gradually moves towards the second disc 571, and the through shaft 56 rotates with the second disc 571. The toothed rake 55 tends to contact the anti-jamming body 576. The anti-jamming body 576 is squeezed and deforms with reference to the main rod 575, forming the anti-jamming body 576. The rotation is from bottom to top. In addition, the cylindrical part 572 has a certain inclined groove on its side. When the anti-jamming body 576 swings to the top, the toothed rake part 55 moves along the upper part of the anti-jamming body 576 to the top. The block 573 works with the plate 574 to block the toothed rake part 55. The plate 574 prevents the toothed rake part 55 from losing weight and falling down instantly, thereby ensuring that the equipment can pass through the corner quickly and normally, and ensuring that the equipment can rotate the filter screen. This avoids jamming. Compared with the existing technology, it reduces unnecessary operation steps and improves the balance of transportation.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
