Abstract
Description
Technical Field
[0001] This application relates to the technical field of rotary kilns, and in particular to a rotary kiln that is easy to clean. Background Technology
[0002] Rotary kilns, as an important industrial calcination equipment, are widely used in the calcination process of materials such as cement, lime, and alumina. With the increasing demands for continuous operation of equipment in industrial production, the long-term stable operation of rotary kilns has become crucial. However, during the calcination process in the kiln, materials are prone to forming scale and lumps, which adhere to the inner wall of the kiln and affect heat transfer efficiency and production quality.
[0003] The existing publication number CN201166514Y, entitled "A Wet Rotary Kiln," belongs to the technical field of rotary kilns for ferrite pre-calcined materials. It includes a kiln body, which is inclined downwards from the inlet end to the outlet end. The internal cavity of the kiln body between the inlet and outlet ends consists of a first equal-diameter cavity, a second equal-diameter cavity, and a third equal-diameter cavity. The diameter of the first equal-diameter cavity is larger than that of the second equal-diameter cavity, and the diameter of the second equal-diameter cavity is larger than that of the third equal-diameter cavity. The first and second equal-diameter cavities are connected by a first annular step, and the second and third equal-diameter cavities are connected by a second annular step. This design slows down the flow rate of the slurry and washing water within the kiln body, facilitating the pre-calcination of the ferrite pre-calcined material and the cleaning of the kiln cavity. It solves the problems existing in current rotary kilns for ferrite pre-calcined materials, such as difficulties in pre-calcination and cleaning of the ferrite pre-calcined material.
[0004] Regarding the aforementioned technologies, the inventors discovered that when cleaning the rotary kiln, water is added to the rotary kiln to rinse away impurities on the inner wall. However, the rotary kiln lacks a dedicated scraping and cleaning component, and the simple water flow is insufficient to completely remove the adhering impurities on the inner wall of the rotary kiln, thus affecting the cleaning effect of the inner wall impurities. Utility Model Content
[0005] In order to overcome the problem that existing rotary kiln cleaning methods lack dedicated scraping and cleaning components and rely solely on water flow to clean impurities on the inner wall of the rotary kiln, which cannot completely remove the adhering impurities and affect the cleaning effect, this application provides a rotary kiln that is easy to clean.
[0006] The rotary kiln provided in this application, which is easy to clean, adopts the following technical solution:
[0007] A rotary kiln for easy cleaning includes a rotary kiln body, a cleaning component, and a removal component. The cleaning component is located on the outer side of the feed inlet of the rotary kiln body. The cleaning component includes a cleaning frame and a perforated frame. The cleaning frame is located on the outer side of the feed inlet of the rotary kiln body. A perforated frame is horizontally slidably assembled on the top surface of the cleaning frame, and a screw-hole rotating rod is horizontally rotatably connected to the end of the perforated frame. A removal component is assembled at the other end of the screw-hole rotating rod. The removal component includes a water rod and connecting plates. One end of the water rod is assembled to the end of the screw-hole rotating rod, and the other end of the water rod is connected to and fixed with a spray ring. Two connecting plates are horizontally and vertically fixed to the other end of the spray ring of the water rod. Two sliding frames are symmetrically and vertically fixed on the vertical end faces of the two connecting plates, and a movable frame is vertically slidably assembled in each of the two sliding frames. A scraper is horizontally fixed on the movable frame on the side of the two connecting plates closest to the water rod, and a needle roller is horizontally rotatably connected to the middle of the movable frame on the side of the two connecting plates closest to the water rod. An iron brush plate is horizontally fixed on the movable frame on the side of the two connecting plates furthest from the water rod.
[0008] By adopting the above technical solution, when cleaning the interior of the rotary kiln body, one end of the water rod in the removal component is fixedly assembled with the end of the screw-hole rotating rod in the cleaning component. The cleaning frame in the cleaning component is pushed to move using roller support, causing the removal component on the cleaning component to insert into the interior of the rotary kiln body. Then, when water is supplied to the water rod during cleaning, the screw-hole rotating rod is started to rotate on the hole frame. The rotating screw-hole rotating rod drives the water rod to rotate circumferentially, which in turn drives the two connecting plates to rotate. The scraper, needle roller, and iron brush plate respectively set on the moving frame of the two connecting plates are used to clean the impurities on the inner wall of the rotary kiln body. The cleaning process involves first using a wire brush to remove floating dust and impurities from the inner wall of the rotary kiln. Simultaneously, scrapers and needle rollers are used to scrape and loosen any adhering impurities, improving the effectiveness of cleaning the inner wall of the rotary kiln. A spray ring then sprays water to rinse away the impurities from the inner wall. The cleaning frame moves laterally on the cleaning machine frame, removing impurities from the inner wall of the rotary kiln. This multi-layered cleaning system, consisting of wire brushes, scrapers, and spray rings, completely removes adhering impurities from the inner wall of the rotary kiln, ensuring a thorough cleaning effect.
[0009] Optionally, a slide bar frame is horizontally fixed on the top surface of the cleaning machine frame, and one end of the hole frame is horizontally slidably assembled onto the slide bar frame.
[0010] By adopting the above technical solution, the sliding rod frame fixed on the top surface of the cleaning frame is used for horizontal sliding of the hole frame and horizontal movement to clean impurities on the inner wall of the rotary kiln.
[0011] Optionally, a hydraulic rod is horizontally fixed to one end of the slide bar bracket, and the output end of the hydraulic rod is fixed to the hole bracket.
[0012] By adopting the above technical solution, the hydraulic rod is extended during cleaning, pushing the hole frame to move laterally on the slide bar frame, which in turn moves the removal parts laterally to clean the impurities on the inner wall of the rotary kiln.
[0013] Optionally, one end of the water rod is connected to a water supply rotating ring, and the outer wall of the water supply rotating ring is connected and fixed to the water supply pipe.
[0014] By adopting the above technical solution, one end of the water inlet pipe of the water rod is connected to a fixed water supply rotating ring, which drives the water supply rotating ring to rotate and supply water when the water rod rotates.
[0015] Optionally, a screw hole insert block is horizontally fixed at one end of the screw hole rotating rod.
[0016] By adopting the above technical solution, the screw hole insert block with the horizontally fixed end of the screw hole rod has multiple vertically through-holes, which are used to cooperate with the locking bolts for locking, installing, removing and cleaning parts.
[0017] Optionally, a plug is horizontally fixed to the end of the water rod, and the plug is slidably inserted into the screw hole plug at the end of the screw hole rotating rod. The plug and the screw hole rotating rod are assembled by locking bolt threads.
[0018] By adopting the above technical solution, the insert at the end of the water rod and the screw hole block at the end of the screw hole rotating rod are slidably inserted. The insert and the screw hole block are then assembled using locking bolt threads, thus completing the fixed assembly of the cleaning and removal parts.
[0019] Optionally, a spring is vertically fixed inside the slide frame, and the other end of the spring is fixed to the movable frame.
[0020] By adopting the above technical solution, in order to ensure that the moving frame moves vertically on the slide frame during cleaning and is in close contact with the inner wall of the rotary kiln body to clean impurities, the deformation force of the spring is used to push the moving frame to move vertically inside the slide frame, so that the scraper and iron brush on the moving frame are in close contact with the inner wall of the rotary kiln body to clean the impurities on the inner wall of the rotary kiln body.
[0021] Optionally, rollers are rotatably connected to the bottom surface of the cleaning frame, and a cleaning motor is horizontally fixed to the end of the hole frame, with the output end of the cleaning motor fixed to the end of the screw hole rotating rod.
[0022] By adopting the above technical solution, rollers are rotatably connected to the bottom surface of the cleaning frame, which facilitates the movement and cleaning of impurities inside the rotary kiln body. At the same time, in order to improve the comprehensiveness of cleaning, the cleaning motor is started to drive the screw hole rotating rod to rotate on the hole frame, which drives the circumference of the removal part to clean the impurities inside the rotary kiln body.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] When cleaning the interior of the rotary kiln body, one end of the water rod in the removal component is fixedly assembled with the end of the screw-hole rotating rod in the cleaning component. The cleaning frame in the cleaning component is then pushed, supported by rollers, causing the removal component to insert into the interior of the rotary kiln body. During cleaning, water is supplied to the water rod, and the screw-hole rotating rod rotates on the mounting frame. The rotating screw-hole rotating rod drives the water rod to rotate circumferentially, causing the two connecting plates to rotate. The scrapers, needle rollers, and iron brushes mounted on the moving frames of the two connecting plates are used to clean and remove impurities from the inner wall of the rotary kiln body. First, a wire brush is used to remove floating dust and impurities from the inner wall of the rotary kiln. Simultaneously, a scraper and needle roller are used to scrape and loosen the adhering impurities, improving the effectiveness of cleaning the inner wall of the rotary kiln. A spray ring then sprays water to rinse away the impurities from the inner wall. The cleaning frame moves laterally on the cleaning frame, removing impurities from the inner wall of the rotary kiln. The combination of the wire brush, scraper, and spray ring forms a multi-layered cleaning system that completely removes adhering impurities from the inner wall of the rotary kiln, ensuring effective cleaning.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] This application discloses a rotary kiln that is easy to clean. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotary kiln for easy cleaning includes a rotary kiln body 1, a cleaning component 2, and a removal component 3. The cleaning component 2 is located on the outer side of the feed inlet of the rotary kiln body 1. The cleaning component 2 includes a cleaning frame 21 and a hole frame 25. The cleaning frame 21 is located on the outer side of the feed inlet of the rotary kiln body 1. The hole frame 25 is horizontally slidably assembled on the top surface of the cleaning frame 21, and a screw-hole rotating rod 27 is horizontally rotatably connected to the end of the hole frame 25. The other end of the screw-hole rotating rod 27 is assembled with the removal component 3. The removal component 3 includes a water rod 31 and a connecting plate 33. One end of the water rod 31 is assembled to the end of the screw-hole rotating rod 27, and the water rod... The other end of the water rod 31 is connected to a spray ring 312. The other end of the spray ring 312 of the water rod 31 is horizontally and vertically fixed with two connecting plates 33. Two sliding frames 34 are symmetrically and vertically fixed on the vertical end face of the two connecting plates 33. A movable frame 35 is vertically slidably assembled in each of the two sliding frames 34. A scraper 351 is horizontally fixed on the movable frame 35 on the side of the two connecting plates 33 closest to the water rod 31. A needle roller 352 is horizontally rotatably connected in the middle of the movable frame 35 on the side of the two connecting plates 33 closest to the water rod 31. An iron brush plate 37 is horizontally fixed on the movable frame 35 on the side of the two connecting plates 33 furthest from the water rod 31. When cleaning the interior of the rotary kiln body 1, one end of the water rod 31 in the removal component 3 is fixedly assembled with the end of the screw hole rotating rod 27 in the cleaning component 2. The cleaning frame 21 in the cleaning component 2 is pushed and supported by the roller 22, causing the removal component 3 on the cleaning component 2 to be inserted into the interior of the rotary kiln body 1. Then, when water is supplied to the water rod 31 during cleaning, the screw hole rotating rod 27 is started to rotate on the hole frame 25. The rotating screw hole rotating rod 27 drives the water rod 31 to rotate circumferentially, which in turn drives the two connecting plates 33 to rotate. The scraper 351, needle roller 352 and iron brush plate 37 respectively set on the moving frame 35 of the two connecting plates 33 are used to remove impurities on the inner wall of the rotary kiln body 1. The cleaning process involves first using a brush 37 to remove floating dust and impurities from the inner wall of the rotary kiln body 1. Simultaneously, a scraper 351 and a needle roller 352 are used to scrape and loosen the impurities adhering to the inner wall of the rotary kiln body 1, improving the effectiveness of cleaning impurities on the inner wall of the rotary kiln body 1. A spray ring 312 is used to spray cleaning water to rinse the impurities on the inner wall of the rotary kiln body 1. The perforated frame 25 moves laterally on the cleaning frame 21, and the lateral movement removes the impurities on the inner wall of the rotary kiln body 1. Thus, the brush 37, scraper 351, and spray ring 312 form a multi-layer cleaning component, which can completely clean the adhering impurities on the inner wall of the rotary kiln, ensuring the cleaning effect of impurities on the inner wall of the rotary kiln.
[0034] Reference Figure 3A sliding rod frame 23 is horizontally fixed on the top surface of the cleaning frame 21, and one end of the perforated frame 25 is horizontally slidably assembled onto the sliding rod frame 23. The sliding rod frame 23 fixed on the top surface of the cleaning frame 21 is used to horizontally slide the perforated frame 25, moving laterally to clean impurities on the inner wall of the rotary kiln. A hydraulic rod 24 is horizontally fixed to one end of the sliding rod frame 23, and the output end of the hydraulic rod 24 is fixed to the perforated frame 25. During cleaning, the hydraulic rod 24 is activated to extend, pushing the perforated frame 25 laterally on the sliding rod frame 23, which in turn moves the removal component 3 laterally to clean impurities on the inner wall of the rotary kiln.
[0035] Reference Figure 5 One end of the water rod 31 is connected to a water supply rotating ring 311, and the outer wall of the water supply rotating ring 311 is connected and fixed to the water supply pipe. The water inlet pipe at one end of the water rod 31 is connected to the fixed water supply rotating ring 311, and when the water rod 31 rotates, it drives the water supply rotating ring 311 to rotate and supply water.
[0036] Reference Figure 4 and Figure 5 One end of the screw-hole rotating rod 27 is horizontally fixed with a screw-hole insert. Multiple screw holes are vertically drilled through the horizontally fixed screw-hole insert at the end of the screw-hole rotating rod 27, used to engage with the locking bolt 321 to lock and install the removal component 3 and the cleaning component 2. A sleeve 32 is horizontally fixed at the end of the water rod 31, and the sleeve 32 is slidably inserted into the screw-hole insert at the end of the screw-hole rotating rod 27. The sleeve 32 and the screw-hole rotating rod 27 are threaded together using the locking bolt 321. The sliding insertion of the sleeve 32 at the end of the water rod 31 into the screw-hole insert at the end of the screw-hole rotating rod 27, combined with the threaded assembly of the sleeve 32 and the screw-hole insert using the locking bolt 321, completes the fixed assembly of the cleaning component 2 and the removal component 3.
[0037] Reference Figure 5 A spring 36 is vertically fixed inside the sliding frame 34, and the other end of the spring 36 is fixed to the movable frame 35. In order to ensure that the movable frame 35 moves vertically on the sliding frame 34 during cleaning and is in close contact with the inner wall of the rotary kiln body 1 to clean impurities, the deformation force of the spring 36 is used to push the movable frame 35 to move vertically inside the sliding frame 34, so that the scraper 351 and the iron brush 37 on the movable frame 35 are in close contact with the inner wall of the rotary kiln body 1 to clean the impurities on the inner wall of the rotary kiln body 1.
[0038] Reference Figure 3 Rollers 22 are rotatably connected to the bottom surface of the cleaning frame 21. A cleaning motor 26 is horizontally fixed to the end of the hole frame 25, and the output end of the cleaning motor 26 is fixed to the end of the screw hole rotating rod 27. The rollers 22 are rotatably connected to the bottom surface of the cleaning frame 21 to facilitate movement and cleaning of impurities inside the rotary kiln body 1. At the same time, in order to improve the comprehensiveness of cleaning, the cleaning motor 26 is started to drive the screw hole rotating rod 27 to rotate on the hole frame 25, which drives the removal part 3 to clean the impurities inside the rotary kiln body 1 circumferentially.
[0039] The implementation principle of a rotary kiln that is easy to clean according to an embodiment of this application is as follows: When cleaning the interior of the rotary kiln body 1 during use, one end of the water rod 31 in the removal component 3 is fixedly assembled with the end of the screw hole rotating rod 27 in the cleaning component 2. The cleaning frame 21 in the cleaning component 2 is pushed to move with the support of the roller 22, which drives the removal component 3 on the cleaning component 2 to insert into the interior of the rotary kiln body 1. Then, when water is supplied to the water rod 31 during cleaning, the screw hole rotating rod 27 is started to rotate on the hole frame 25. The rotating screw hole rotating rod 27 drives the water rod 31 to rotate circumferentially, which drives the two connecting plates 33 to rotate. The scraper 351, needle roller 352 and iron brush plate 37 respectively set on the moving frame 35 of the two connecting plates 33 are used to clean and remove impurities on the inner wall of the rotary kiln body 1. During cleaning, the iron brush plate 37 is first used to remove floating dust and impurities on the inner wall of the rotary kiln body 1. At the same time, the scraper 351 and needle roller 352 are used to clean the inner wall of the rotary kiln body 1. Impurities adhering to the inner wall are scraped off and loosened to improve the effectiveness of cleaning impurities on the inner wall of the rotary kiln body 1. The cleaning water is sprayed by the spray ring 312 to rinse the impurities on the inner wall of the rotary kiln body 1. In order to ensure that the moving frame 35 moves vertically on the sliding frame 34 during cleaning and is close to the inner wall of the rotary kiln body 1 to clean impurities, the deformation force of the spring 36 is used to push the moving frame 35 to move vertically inside the sliding frame 34, so that the scraper 351 and the iron brush 37 on the moving frame 35 are close to the inner wall of the rotary kiln body 1. During cleaning, the hydraulic rod 24 is activated to extend and push the hole frame 25 to move laterally on the sliding rod frame 23, which drives the removal part 3 to move laterally to clean the impurities on the inner wall of the rotary kiln. The hole frame 25 moves laterally on the cleaning frame 21 to remove the impurities on the inner wall of the rotary kiln body 1. The cleaning motor 26 is activated to drive the screw hole rotating rod 27 to rotate on the hole frame 25, which drives the removal part 3 to clean the impurities inside the rotary kiln body 1 circumferentially.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
