Description

Technical Field

[0001] This utility model relates to the field of automated cleaning equipment technology, specifically a rotary cleaning and drying device for powder cylinders. Background Technology

[0002] In many industrial production sectors, such as chemical, food, and pharmaceutical industries, powder containers are common material storage and transportation containers. During use, these containers accumulate residues of various powders. If these residues are not cleaned promptly, they can affect the quality of subsequent materials and lead to cross-contamination between different materials, impacting product purity and performance. Traditional powder container cleaning relies primarily on manual labor. Manual cleaning is labor-intensive, requiring workers to bend over and reach into the container for extended periods to wipe and rinse, leading to fatigue and reduced efficiency. Furthermore, manual cleaning struggles to ensure even and thorough cleaning; corners and crevices are difficult to clean effectively, leaving residual stains and impurities that can affect subsequent use. The drying process after cleaning is also cumbersome, typically involving natural air drying or simple manual hot air drying, which is inefficient and yields poor results, often leaving moisture residue inside the container, causing the material to become damp and deteriorate.

[0003] Meanwhile, although some powder cylinder cleaning or drying devices exist on the market, most of these devices are separate, resulting in high purchase and operating costs, as well as high maintenance costs. Furthermore, some devices fail to achieve satisfactory cleaning and drying results, unable to meet the required cleanliness of the powder cylinders. Utility Model Content

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.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model provides a rotary cleaning and drying device for powder cylinders, including a box 1 with a hollow bottom. Both the left and right side walls of the box 1 have passage openings 101 at their lower parts, and both passage openings 101 are covered with safety doors 2. First cylinders 3 are fixedly installed on both sides of the top plate of the box 1, arranged in a forward direction. The piston rod ends of the first cylinders 3 are fixedly installed on the safety doors 2 located below them. A fixing frame 5 is fixedly installed in the middle of the top plate of the box 1, and a second cylinder 6 arranged in a reverse direction is fixedly installed on the fixing frame 5. The piston rod ends of the second cylinder 6 are connected to the safety doors 2. A lifting plate 8 is connected via a connecting mechanism 7. A rotary motor 9 is fixedly installed in the middle of the lifting plate 8. A rotating rod 10 that penetrates the top plate of the box 1 is fixedly installed on the output shaft of the rotary motor 9. A powder cylinder positioning plate 11 is fixedly installed at the bottom end of the rotating rod 10. A support rod 12 is fixedly installed on the rear side wall of the box 1. A support frame 13 is fixedly installed on the support rod 12. A third cylinder 14 arranged in the opposite direction is fixedly installed on the support frame 13. A nozzle mounting bracket 15 is fixedly installed on the piston rod end of the third cylinder 14. A high-pressure rotary nozzle 16 is installed on the nozzle mounting bracket 15.

[0022] The rotary cleaning and drying device for powder cylinders has access openings 101 on the lower part of its left and right side walls, covered by safety doors 2, facilitating the entry and exit of the powder cylinders. The safety doors also ensure the enclosure of the housing 1 during cleaning and drying, guaranteeing operational safety and preventing contamination of the surrounding work environment. A first cylinder 3 on the top plate of the housing 1 drives the safety door 2 to rise and fall, automating its opening and closing and improving operational convenience and efficiency. A second cylinder 6 on the fixed frame 5 drives a lifting plate 8 to rise and fall via a connecting mechanism 7, which in turn drives a rotary motor 9 and a rotating rod 10 to move up and down. The powder cylinder positioning plate 11 at the bottom of the rotating rod 10 presses the bottom of the powder cylinder firmly, and then the rotary motor 9... The rotating rod 10 is driven to rotate, which in turn drives the powder cylinder positioning plate 11 and the powder cylinder it holds to rotate. The third cylinder 14 drives the nozzle mounting bracket 15 to move into the powder cylinder. The high-pressure rotating nozzle 16 is connected in sequence to the cleaning equipment and drying equipment installed on the housing 1. After being pressurized by the pressurizing equipment, the cleaning liquid and drying hot air are sprayed out in a 360° rotation through the high-pressure rotating nozzle 16 to clean and dry the inside of the powder cylinder. The cleaning and drying are combined into one device, and the uniformity of cleaning and drying is ensured. This significantly improves the cleaning and drying effect, increases the cleaning efficiency of the powder cylinder, reduces the tediousness of manual operation and the potential safety hazards, reduces the labor intensity of workers, and greatly reduces costs.

[0023] The front wall of the housing 1 is equipped with a transparent glass door 17. The left side of the transparent glass door 17 is hinged to the housing 1, and the right side is locked to the housing 1 by a convenient manual lock 18. The transparent glass door 17 allows operators to observe the cleaning and drying process of the powder cylinder inside the housing 1 in real time and detect any abnormalities in a timely manner. The convenient manual lock 18 facilitates the quick opening and closing of the transparent glass door 17, improving the ease of operation. Two slide rails 19 are fixedly installed on both the left and right side walls of the housing 1, and two safety doors 2 are fixedly mounted on them. Two pulleys 20 are fixedly installed, one-to-one with each other in the slide rail 19. The pulleys 20 roll in the slide rail 19, which makes the opening and closing of the safety door 2 smoother, reduces friction, improves the convenience and stability of operation, and also extends the service life of the safety door 2 and the box 1. Two parallel L-shaped support plates 4 are fixedly installed at the bottom of the box 1. The two L-shaped support plates 4 can reinforce the two sides of the central hollow conveyor belt entering the lower part of the box 1, so as to make the powder cylinder more firmly fixed.

[0024] The aforementioned connecting mechanism 7 includes a connecting plate 701 and two connecting rods 702. The connecting plate 701 is fixedly installed on the piston rod end of the second cylinder 6. The two connecting rods 702 are slidably connected to the fixed frame 5 through linear bearings. The two ends of the two connecting rods 702 are respectively fixedly installed on the connecting plate 701 and the lifting plate 8, ensuring that the lifting plate 8 can move up and down smoothly during the extension and retraction of the piston rod of the second cylinder 6, thereby improving the stability and reliability of the device and reducing the impact that the shaking of the lifting plate 8 may have on the rotary motor 9 and the powder cylinder positioning plate 11.

[0025] Two springs 21 are fixedly installed on the powder cylinder positioning plate 11. The bottom ends of the two springs 21 are fixedly installed with the powder cylinder pressure plate 22. When the powder cylinder positioning plate 11 moves downward, the powder cylinder pressure plate 22 first contacts the bottom surface of the powder cylinder. Under the pressure of the spring, it plays a good role in fixing the bottom surface of the powder cylinder, preventing the powder cylinder from shaking or shifting during rotation, and ensuring the stability and safety of the cleaning and drying process.

[0026] When using the rotary cleaning and drying device for powder cylinders, multiple powder cylinders to be cleaned are placed upside down at a predetermined distance on the centrally hollowed-out conveyor belt. The conveyor belt then runs (taking the conveyor belt conveying from right to left as an example). At this time, the first cylinder 3 on the right side of the top plate of the housing 1 starts to work, driving the right safety door 2 to move upward and opening the right passage 101. The powder cylinders pass through the right passage 101 into the housing 1. When the powder cylinder is directly below the powder cylinder positioning plate 11, the conveyor belt stops running, and the first cylinder 3 on the right side of the top plate of the box 1 starts working again, driving the safety door 2 on the right side to move downward and cover and close the passage 101 on the right side again. The second cylinder 6 on the fixed frame 5 starts working, and its piston rod drives the lifting plate 8 to move downward through the connecting mechanism 7. The lifting plate 8 drives the rotary motor 9 and the rotating rod 10 on it to move downward. The powder cylinder positioning plate 11 at the bottom of the rotating rod 10 also descends. The powder cylinder pressure plate 22 first contacts the bottom surface of the powder cylinder. As the powder cylinder positioning plate 11 continues to descend, the spring 21 is compressed. Under the pre-tightening force of the spring 21, the powder cylinder pressure plate 22 presses tightly against the bottom surface of the powder cylinder, and firmly fixes the powder cylinder.

[0027] After the powder cylinder is securely fixed, the third cylinder 14 on the support frame 13 starts working, its piston rod extends, driving the nozzle mounting frame 15 to move, allowing the high-pressure rotary nozzle 16 mounted on the nozzle mounting frame 15 to enter the interior of the powder cylinder. The high-pressure rotary nozzle 16 is connected to the cleaning equipment and pressurizing equipment installed on the housing 1. After being pressurized, the cleaning fluid is sprayed out through the high-pressure rotary nozzle 16 in a 360° rotation, performing a comprehensive cleaning of the interior of the powder cylinder. At the same time, the rotary motor 9 starts working, driving the rotating rod 10 to rotate, which in turn drives the fixed powder cylinder to rotate slowly in the opposite direction to the rotation of the high-pressure rotary nozzle 16, performing a comprehensive cleaning of the interior of the powder cylinder. After cleaning, the high-pressure rotary nozzle 16 switches to connect to the drying equipment and the pressurizing equipment. After being pressurized, the drying hot air is sprayed out through the high-pressure rotary nozzle 16 in a 360° rotation, drying the interior of the powder cylinder.

[0028] After the cleaning and drying operation is completed, the piston rod of the third cylinder 14 retracts, causing the nozzle mounting bracket 15 and the high-pressure rotary nozzle 16 to exit from the powder cylinder and then reset. The piston rod of the second cylinder 6 retracts, causing the lifting plate 8, rotary motor 9, rotating rod 10, powder cylinder positioning plate 11, etc. to rise and then reset. The two first cylinders 3 on the top plate of the box 1 start working, causing the two safety doors 2 to move upward, opening both passages 101. The conveyor belt continues to run, passing the cleaned and dried powder cylinder out from the passage 101 on the left side of the box 1. At the same time, the next powder cylinder to be cleaned enters the box 1 through the passage 101 on the right side. When it is directly below the powder cylinder positioning plate 11, the conveyor belt stops running, and the two first cylinders 3 on the top plate of the box 1 start working again, causing the two safety doors 2 to move downward, covering and closing the two passages 101 again.

[0029] By repeating this process, continuous cleaning and drying operations can be achieved for multiple powder cylinders.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
