Description

Technical Field

[0001] This utility model relates to cleaning device technology, specifically a cleaning device for graphite felt production. Background Technology

[0002] Graphite felt is classified into three types based on the raw material used: pitch-based graphite felt, polyacrylonitrile-based graphite felt, and adhesive-based graphite felt. Its main purpose is as a heat insulation and heat insulation material for monocrystalline silicon smelting furnaces. In the chemical industry, it can be used as a filter material for high-purity corrosive chemical reagents. During the production of graphite felt, dust, debris, and other impurities will adhere to the surface, so a cleaning device is needed to clean it.

[0003] Existing cleaning devices typically use roller brushes combined with water spraying to clean the surface of graphite felt. However, this method results in only one side of the graphite felt being brushed during a single cleaning cycle, necessitating manual turning after each cleaning and subsequent cleaning, thus prolonging the cleaning time and reducing the cleaning efficiency. Therefore, we propose a cleaning device for graphite felt production to address the aforementioned problems. Utility Model Content

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-4 As shown, a cleaning device for graphite felt production includes a base 1, a cleaning zone 2 located at the top center of the base 1, and outer edge plates 3 fixedly connected to all four sides of the base 1. A water spray structure 4 and a cleaning structure 5 are respectively provided on the front and rear outer edge plates 3. A flipping assembly includes a first frame 6 fixedly connected to the top of the left and right outer edge plates 3, a first screw 7 rotatably connected inside the first frame 6, and a motor 8 fixedly connected to the top of the first frame 6. The output end of the motor 8 is fixedly connected to the adjacent end of the adjacent first screw 7. A lifting block 21 is connected to the side thread. The lifting block 21 is slidably connected inside the first frame 6. A rotating shaft 9 is rotatably connected to one side of the lifting block 21. A gear 10 is fixedly connected to the outside of the rotating shaft 9. A push rod 11 is also fixedly connected to the outside of the rotating shaft 9 and between the two gears 10. A clamping assembly is fixedly connected to one end of the rotating shaft 9. An elastic telescopic rod 12 is fixedly connected to the outer wall of one side of the first frame 6. A U-shaped rod 13 is slidably connected inside the elastic telescopic rod 12. A drive plate 14 is fixedly connected to one end of the U-shaped rod 13. An arc-shaped gear frame 15 is fixedly connected to one end of the drive plate 14.

[0021] It should be noted that large-format filters are used in cleaning area 2 to facilitate the downward flow of wastewater after cleaning. A wastewater collection pipe is installed below. Both the water spray structure 4 and the cleaning structure 5 are existing mature technologies. Motor 8 drives the first screw 7 to rotate, which in turn drives the lifting block 21 to move up and down, thereby changing the height of the rotating shaft 9 and the graphite felt. The two motors 8 need to be driven synchronously by a PLC. Gear 10 facilitates the rotation of the rotating shaft 9 when it contacts and meshes with the arc-shaped gear frame 15, thereby causing the second frame 16 and the graphite felt to flip over. An additional ratchet mechanism needs to be installed on the rotating shaft 9 to ensure that it can only rotate in one direction, or a damping rotating shaft can be used to reduce the force required to rotate the rotating shaft 9. The force is greater than that required to move the U-shaped rod 13, ensuring that the rotating shaft 9 will not reverse when the push rod 11 pushes the drive plate 14 during descent. A spring is installed inside the elastic telescopic rod 12 to ensure that the U-shaped rod 13 is always subjected to a force in the direction of the rotating shaft 9. This allows the arc-shaped gear frame 15 to remain in a position that can mesh with the gear 10 when the push rod 11 is not in contact with the drive plate 14. The flipping component allows the graphite felt to be automatically flipped after one side is cleaned during a single cleaning process, eliminating the need for secondary cleaning and thus reducing the time required for cleaning the graphite felt and improving its cleaning efficiency.

[0022] The clamping assembly includes a second frame 16 fixedly connected to one end of the rotating shaft 9. A second screw 17 is threadedly connected to the inner side of the second frame 16. A handwheel 18 is fixedly connected to one end of the second screw 17. Moving blocks 19 are threadedly connected to the front and rear sides of the outer side of the second screw 17. The moving blocks 19 are slidably connected within the second frame 16. A clamp 20 is fixedly connected to one side of the moving blocks 19. The clamp 20 can be any existing mature clamp, as long as it can clamp and fix the graphite felt. The handwheel 18 can easily rotate the second screw 17 so that it drives the two moving blocks 19 and the clamp 20 to move through the threaded engagement with the outer moving blocks 19, thereby adjusting the clamping position of the graphite felt and improving clamping stability.

[0023] The graphite felt is placed between the four clamps 20. The graphite felt is held by the four clamps 20, which makes it easy to flip it together with the four clamps 20 when turning it over, thus reducing the number of times the graphite felt needs to be cleaned.

[0024] The push rod 11 is V-shaped with an included angle of 45 degrees. The V-shaped push rod 11 facilitates the contact and push of the drive plate 14 through the transition fillet on it, so that the arc-shaped gear frame 15 does not mesh with the gear 10 during the descent, thus preventing the rotating shaft 9 from rotating. This eliminates the need for an additional power source to drive the rotating shaft 9, saving structural costs.

[0025] The second screw 17 has threads with opposite directions on its front and rear sides. When the second screw 17 rotates in one direction, the two moving blocks 19 on it move in opposite directions, which makes it convenient to adjust the position of the two sets of clamps 20.

[0026] In practical implementation of this invention: First, adjust the spacing of the clamps 20 according to the length of the graphite felt. Then, rotate the handwheel 18 to drive the second screw 17 to rotate. During rotation, the screw 17, through its threaded engagement with the moving blocks 19, causes the two moving blocks 19 to move relative to each other to a suitable position. Next, place the graphite felt on the cleaning area 2 and operate the clamps 20 to hold it. Then, connect the device to a power source and control the water spray structure 4 and cleaning structure 5 via a controller to clean the surface of the graphite felt. After cleaning one side, stop the water spray structure 4 and cleaning structure 5 via the controller. Then, control the two motors 8 to operate. The motors 8 drive the first screw 7 to rotate, causing the lifting block 21 to drive the rotating shaft 9 and the second frame 16 to rise as a whole. During the rising process, the gear 10 will engage with the arc-shaped gear... When frame 15 engages, it causes the rotating shaft 9, the second frame 16, the clamp 20, and the graphite felt to rotate 180 degrees. Then, the output of motor 8 is reversed by the controller, causing the lifting block 21 to decrease in height. When the height decreases, push rod 11 contacts drive plate 14 before gear 10. By squeezing drive plate 14 to one side, it causes U-shaped rod 13 to retract within elastic telescopic rod 12, causing arc-shaped gear frame 15 to move to a position where it will not engage with gear 10, until it is lowered to the lowest point. After push rod 11 no longer contacts drive plate 14, U-shaped rod 13, under the action of spring force within elastic telescopic rod 12, drives drive plate 14 and arc-shaped gear frame 15 to reset. At this time, the graphite felt, which has been lowered to the lowest point, is in a flipped state. The water spray structure 4 and cleaning structure 5 continue to work by controlling the controller to continue cleaning the flipped graphite felt until cleaning is complete.
