Description

Technical Field

[0001] This invention relates to the field of plasma cleaning technology, and in particular to a drum-type vacuum plasma cleaner. Background Technology

[0002] In traditional industrial production, material surfaces often contain various contaminants such as grease, oxides, and dust. These contaminants can seriously affect the quality of subsequent processes, such as reducing the bonding strength of materials and affecting the uniformity of coatings. To solve these problems, plasma cleaning technology has gradually developed. Plasma cleaning has advantages such as good cleaning effect, no residue, and environmental friendliness. However, in actual production, many workpieces to be cleaned have complex shapes and diverse sizes, making it difficult for traditional planar plasma cleaning equipment to meet the needs of uniform cleaning.

[0003] Rotary plasma cleaners are developed based on plasma cleaning technology. Their rotary design has unique advantages, allowing workpieces to tumble continuously inside the drum, ensuring that all surfaces of each workpiece are fully exposed to the plasma. However, during use, flat and complex materials tumble poorly inside the drum, resulting in uneven cleaning of flat and complex materials. Furthermore, when cleaning complex materials, dust inside the material cannot be discharged, requiring the material to be removed for cleaning, increasing the number of steps and affecting processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a drum-type vacuum plasma cleaner.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drum-type vacuum plasma cleaner includes a housing, the interior of which is a sealed environment. A cleaning chamber is rotatably installed inside the housing, and a drum assembly is rotatably installed inside the cleaning chamber. The drum assembly includes a cylindrical screen, two side plates, two support rings, and several side plates. The two support rings are fixedly installed on both sides of the cylindrical screen. The several side plates are evenly distributed in a circumferential shape inside the cylindrical screen, and the height of the side plates is greater than the height of the side plates.

[0007] A plasma device is fixedly installed inside the cleaning chamber. An electrode rod is fixedly installed on the side wall of the plasma device. A cleaning assembly is movably installed on the outside of the electrode rod. The cleaning assembly includes a first slide, a second slide, a cleaning ring, and a slip ring. The first slide and the second slide are slidably installed on the outside of the electrode rod. The cleaning ring and the slip ring are movably installed on the outside of the electrode rod. The cleaning ring and the slip ring are rotatably connected. The slip ring is rotatably fitted onto the outside of the first slide.

[0008] In the aforementioned drum-type vacuum plasma cleaner, a rotating shaft and four limiting wheels are rotatably installed inside the cleaning chamber. One of the limiting wheels is fixedly installed on the outside of the rotating shaft. The limiting wheels are evenly distributed on the outside of the support ring. A second gear is fixedly installed on the side wall of one of the support rings, and a third gear is fixedly installed on the side wall of the rotating shaft. The second and third gears mesh with each other. A first motor is fixedly installed inside the housing. A third belt is provided between the output shaft of the first motor and the rotating shaft.

[0009] In the aforementioned drum-type vacuum plasma cleaner, a drive chamber is fixedly installed inside the housing, an electric push rod is fixedly installed on the outside of the drive chamber, a rack is fixedly connected to the output end of the electric push rod, and a gear is fixedly installed on the side wall of the cleaning chamber. The rack and gear are both located inside the drive chamber, and the rack and gear mesh with each other.

[0010] In the aforementioned drum-type vacuum plasma cleaner, a sealing cover is rotatably installed on the side wall of the housing, the sealing cover corresponds to the cleaning chamber, an observation cylinder is fixedly installed inside the sealing cover, the observation cylinder corresponds to the cylindrical screen, a dust collection plate is provided inside the cleaning chamber, the dust collection plate is located below the cylindrical screen, and a vacuum detector is fixedly installed on the side wall of the cleaning chamber.

[0011] In the aforementioned drum-type vacuum plasma cleaner, several evenly distributed flexible strips are rotatably installed between slide one and slide two. Several evenly distributed rollers are rotatably installed on the side walls of slide one and slide two. A belt one is sleeved between the rollers on one side wall of slide one and the flexible strips, and a belt two is sleeved between the rollers on the side wall of slide two and the flexible strips.

[0012] In the aforementioned drum-type vacuum plasma cleaner, the roller on one side wall of the slide frame abuts against the inner wall of the slip ring, and the outer peripheral wall of the slip ring is provided with a slot, which is slidably installed on the outer side of side plate one and side plate two. The roller on the second side wall of the slide frame abuts against the inner wall of the cylindrical screen.

[0013] In the aforementioned drum-type vacuum plasma cleaner, a dust cover is fixedly installed on the side wall of the electrode rod near the plasma device. The dust cover and the slide are in contact with each other. A spring is provided between the inner side of the dust cover and the side wall of the cleaning ring. A counterweight is fixedly installed on the side wall of the cleaning ring. Several evenly distributed ball bearings are provided between the cleaning ring and the electrode rod.

[0014] In the aforementioned drum-type vacuum plasma cleaner, two evenly distributed semi-circular brushes are fixedly installed on the outer side of the cleaning ring, and a spring top block is movably installed between the two semi-circular brushes. The spring top block and the side plate abut against each other, and the semi-circular brushes abut against the cylindrical screen.

[0015] Compared with existing technologies, the advantages of this invention are:

[0016] 1. This invention utilizes the cooperation between the cleaning chamber and the cylindrical screen to enable the cylindrical screen to rotate during plasma cleaning. The rotation of side plates one and two, along with the rotation of the cylindrical screen, causes the material to tumble, improving the uniformity of the plasma cleaning. Simultaneously, the tumbling and impact of the material against the cylindrical screen cleans the dust from its sidewalls. An electric actuator drives the cleaning chamber to continuously switch between horizontal and vertical positions. During this continuous switching, the material inside the cylindrical screen tumbles and shakes. This continuous switching of the cleaning chamber increases the frequency and intensity of the material's tumbling within the cylindrical screen, further enhancing the uniformity of the plasma cleaning.

[0017] 2. This invention utilizes the cooperation between the flexible strip and the cylindrical screen. During the rotation of the cylindrical screen, the rotation of the rollers on the side walls of the first and second slides causes the flexible strip to rotate in the same direction as the cylindrical screen. The rotation of the flexible strip throws the material upward, increasing the height of the material tumbling and enhancing the collision force between materials and between the material and the cylindrical screen. This further improves the cleaning of dust inside the cylindrical screen and dust on the surface of the material.

[0018] 3. This invention, through the cooperation between the cleaning ring and the slide frame one, allows the cleaning ring to rotate along with the cylindrical screen during rotation. When the side plate two abuts against the spring top block, the cleaning ring pulls the top and bottom flexible strips, causing the slide frame one to move towards the slide frame two. At this time, the rotation range of the remaining flexible strips increases. When the top and bottom flexible strips are taut, the spring top block contracts, and the cleaning ring returns to its original position via the torsion spring. The slide frame one also returns to its original position via the spring one. Through the intermittent rotation of the cleaning ring, the rotation range of the flexible strips intermittently increases, improving the coverage area of ​​the flexible strips and the height of material tumbling, further enhancing the uniformity of plasma cleaning of the material.

[0019] 4. This invention utilizes the cooperation between the cleaning ring and the flexible strip. When the cleaning chamber switches from horizontal to vertical, the cleaning ring drives the slide one to slide two. At this time, the flexible strip moves and twists along with the cleaning ring. Through the twisting of the flexible strip, the material is evenly distributed on the side wall of slide two, improving the uniformity of plasma cleaning. When the cleaning chamber switches from vertical to horizontal, the cleaning ring drives slide one back to its original position. Slide one pulls the flexible strip. Through the movement of the flexible strip, the material is quickly and evenly distributed inside the cylindrical screen, improving the uniformity and efficiency of plasma cleaning. At this time, the cleaning ring reverses direction through the pull of the torsion spring and the flexible strip, cleaning the inner wall of the cylindrical screen and removing dust from the side wall of the cylindrical screen, preventing clogging and improving the cleanliness inside the cylindrical screen.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Reference Figure 1 - Figure 10 As shown, a drum-type vacuum plasma cleaner includes a housing 1. The interior of the housing 1 is a sealed environment. A cleaning chamber 15 is rotatably installed inside the housing 1. A drum assembly is rotatably installed inside the cleaning chamber 15. The drum assembly includes a cylindrical screen 153, a second side plate 156, two support rings 154, and several first side plates 155. The two support rings 154 are fixedly installed on both sides of the cylindrical screen 153. Several first side plates 155 and second side plates 156 are evenly distributed in a circumferential shape inside the cylindrical screen 153. The height of the second side plate 156 is greater than the height of the first side plate 155.

[0034] A plasma device 21 is fixedly installed inside the cleaning chamber 15. An electrode rod 213 is fixedly installed on the side wall of the plasma device 21. A cleaning assembly is movably installed on the outside of the electrode rod 213. The cleaning assembly includes a first slide 221, a second slide 222, a cleaning ring 23, and a slip ring 231. The first slide 221 and the second slide 222 are slidably installed on the outside of the electrode rod 213. The cleaning ring 23 and the slip ring 231 are movably installed on the outside of the electrode rod 213. The cleaning ring 23 and the slip ring 231 are rotatably connected. The slip ring 231 is rotatably fitted onto the outside of the first slide 221.

[0035] like Figure 2 and Figure 3 As shown, a sealing cover 11 is rotatably installed on the side wall of the housing 1, and the sealing cover 11 corresponds to the cleaning chamber 15. An observation tube 12 is fixedly installed inside the sealing cover 11, and the observation tube 12 corresponds to the cylindrical screen 153. A dust collection plate 151 is provided inside the cleaning chamber 15, and the dust collection plate 151 is located below the cylindrical screen 153. A vacuum detector 14 is fixedly installed on the side wall of the cleaning chamber 15.

[0036] After the material is filled into the cylindrical screen 153, the sealing cover 11 is closed. At this time, the vacuum device inside the shell 1 performs vacuum treatment on the inside of the shell 1. After the vacuum detector 14 responds, the plasma device 21 is started, and the material is plasma cleaned inside the cleaning chamber 15.

[0037] like Figure 3 and Figure 6 As shown, a rotating shaft 162 and four limiting wheels 163 are rotatably installed inside the cleaning chamber 15. One of the limiting wheels 163 is fixedly installed on the outside of the rotating shaft 162. The limiting wheels 163 are evenly distributed on the outside of the support ring 154. A gear 2 152 is fixedly installed on the side wall of one of the support rings 154. A gear 3 164 is fixedly installed on the side wall of the rotating shaft 162. Gear 2 152 and gear 3 164 mesh with each other. A motor 161 is fixedly installed inside the housing 1. A belt 3 165 is provided between the output shaft of motor 161 and the rotating shaft 162. A drive chamber 13 is fixedly installed inside the housing 1. An electric push rod 133 is fixedly installed on the outside of the drive chamber 13. A rack 132 is fixedly connected to the output end of the electric push rod 133. A gear 131 is fixedly installed on the side wall of the cleaning chamber 15. Both the rack 132 and gear 131 are located inside the drive chamber 13. The rack 132 and gear 131 mesh with each other.

[0038] During plasma cleaning, the electric actuator 133 and motor 161 are activated. Motor 161 drives the rotating shaft 162 to rotate. The rotating shaft 162 drives the support ring 154 and the cylindrical screen 153 to rotate via gears 152 and 164. The cylindrical screen 153 drives the side plates 155 and 156 to rotate. As the side plates 155 and 156 follow the rotation of the cylindrical screen 153, the material tumbles during the rotation of the cylindrical screen 153, improving the uniformity of the plasma cleaning process. The tumbling and impact of the material against the cylindrical screen 153 cleans the dust on the side wall of the cylindrical screen 153. The electric actuator 133 continuously pushes the rack 132, causing the rack 132 to move back and forth continuously. Through the gear 131, the cleaning chamber 15 is continuously moved horizontally and vertically. During the continuous switching between horizontal and vertical positions of the cleaning chamber 15, the material inside the cylindrical screen 153 tumbles and shakes. By continuously switching the state of the cleaning chamber 15, the frequency and force of the material tumbling inside the cylindrical screen 153 are increased, further improving the uniformity of the plasma cleaning of the material.

[0039] like Figure 3 , Figure 8 and Figure 9 As shown, several evenly distributed flexible strips 22 are rotatably installed between slide one 221 and slide two 222. Several evenly distributed rollers 223 are rotatably installed on the side walls of slide one 221 and slide two 222. A belt one 224 is sleeved between the rollers 223 and the flexible strips 22 on the side wall of slide one 221, and a belt two 225 is sleeved between the rollers 223 and the flexible strips 22 on the side wall of slide two 222.

[0040] like Figure 3 , Figure 5 and Figure 8 As shown, the roller 223 on the side wall of the slide 221 abuts against the inner wall of the slip ring 231. The outer peripheral wall of the slip ring 231 is provided with a groove 236. The groove 236 is slidably installed on the outer side of the side plate 155 and the side plate 256. The roller 223 on the side wall of the slide 222 abuts against the inner wall of the cylindrical screen 153.

[0041] During the rotation of the cylindrical screen 153, the slip ring 231 rotates along with the cylindrical screen 153, causing the rollers 223 on the side wall of the first slide 221 to rotate. The rollers 223 on the side wall of the second slide 222 rotate with the rotation of the cylindrical screen 153. Through the rotation of the rollers 223 on the side walls of the first slide 221 and the second slide 222, the flexible strip 22 rotates in the same direction as the cylindrical screen 153. The rotation of the flexible strip 22 throws the material upward, increasing the height of the material tumbling and increasing the force of the collision between materials and between the material and the cylindrical screen 153, thereby further improving the cleaning of dust inside the cylindrical screen 153 and dust on the surface of the material.

[0042] like Figure 5 , Figure 8 and Figure 10 As shown, two evenly distributed semi-circular brushes 235 are fixedly installed on the outer side of the cleaning ring 23. A spring top block 234 is movably installed between the two semi-circular brushes 235. The spring top block 234 abuts against the side plate 156, and the semi-circular brushes 235 abut against the cylindrical screen 153.

[0043] like Figure 3 , Figure 4 and Figure 8 As shown, a dust cover 211 is fixedly installed on the side wall of the electrode rod 213 near the plasma device 21. The dust cover 211 and the slide 222 are in contact. A spring 212 is provided between the inner side of the dust cover 211 and the side wall of the cleaning ring 23. A counterweight 232 is fixedly installed on the side wall of the cleaning ring 23. Several evenly distributed balls 233 are provided between the cleaning ring 23 and the electrode rod 213.

[0044] A torsion spring is provided at the rotating connection between the cleaning ring 23 and the slide 221. During the rotation of the cylindrical screen 153, when the side plate 156 abuts against the spring top block 234, the cleaning ring 23 rotates with the cylindrical screen 153. The cleaning ring 23 pulls the top and bottom flexible strips 22. The slide 221 drives the cleaning ring 23 and the slip ring 231 to move towards the slide 222, thereby increasing the rotation range of the remaining flexible strips 22. When the top and bottom flexible strips 22 are taut, the spring top block 234 retracts and moves away from the side plate 156. The cleaning ring 23 returns to its original position through the torsion spring, and the slide 221 and the slip ring 231 return to their original position through the spring 212. Through the intermittent rotation of the cleaning ring 23, the rotation range of the flexible strips 22 is intermittently increased, thereby increasing the coverage area of ​​the flexible strips 22 and the height of material tumbling, and further improving the uniformity of material plasma cleaning.

[0045] Further reference Figure 3 and Figure 8To explain, during the continuous switching between horizontal and vertical positions of the cleaning chamber 15, when the cleaning chamber 15 switches from horizontal to vertical, the cleaning ring 23, through the counterweight 232, drives the slide 1 221 and the slip ring 231 to move towards the slide 222. At this time, the cleaning ring 23 pulls the flexible strip 22, causing the flexible strip 22 to twist along with the cylindrical screen 153. Through the twisting of the flexible strip 22, the material is evenly distributed on the side wall of the slide 222, improving the uniformity of the plasma cleaning of the material. When the cleaning chamber 15 switches from vertical to horizontal, the spring 1 212 is released, and the cleaning ring 23 drives the slide 1 221 and the slip ring 231 back to their original positions. When the slide 221 returns to its original position, the slide 221 pulls the flexible strip 22, causing the flexible strip 22 to move the material quickly. Through the movement of the flexible strip 22, the material is quickly and evenly distributed inside the cylindrical screen 153, improving the uniformity and efficiency of the plasma cleaning of the material. At this time, the cleaning ring 23 reverses due to the pull of the torsion spring and the flexible strip 22, causing the cleaning ring 23 to reverse during the return process. The cleaning ring 23 cleans the inner wall of the cylindrical screen 153, allowing the dust on the side wall of the cylindrical screen 153 to be discharged, preventing the cylindrical screen 153 from clogging and improving the cleanliness of the inside of the cylindrical screen 153.

[0046] The working principle and usage of this invention are explained in detail below: After the material is filled into the cylindrical screen 153, the vacuum device evacuates the interior of the housing 1. After the vacuum detector 14 responds, the plasma device 21, the electric actuator 133, and the motor 161 are started. The motor 161 drives the cylindrical screen 153 to rotate, which in turn drives the side plates 155 and 156 to rotate. As the side plates 155 and 156 rotate with the cylindrical screen 153, the material tumbles during the rotation of the cylindrical screen 153, improving the uniformity of the plasma cleaning. Simultaneously, the tumbling and impact of the material against the cylindrical screen 153 cleans the dust from the side walls of the cylindrical screen 153. During the rotation of the 153, the side rollers 223 of slide 1 221 and slide 2 222 rotate, causing the flexible strips 22 to rotate in the same direction as the cylindrical screen 153. The rotation of the flexible strips 22 throws the material upwards, increasing the height of the material tumbling and enhancing the collision force between materials and between materials and the cylindrical screen 153. This further improves the cleaning of dust inside the cylindrical screen 153 and on the surface of the material. When side plate 2 156 abuts against the spring top block 234, the cleaning ring 23 rotates with the cylindrical screen 153, pulling the top and bottom flexible strips 22. Slide 1 221 moves towards slide 2 222, increasing the rotation range of the remaining flexible strips 22. When the top and bottom flexible strips 22 are taut, the cleaning ring... 23. By returning to its original position via the torsion spring, slide 221 and slip ring 231 are returned to their original position via spring 212. The intermittent rotation of the cleaning ring 23 intermittently increases the rotation range of the flexible strip 22, improving the coverage area of ​​the flexible strip 22 and the height of material tumbling, further enhancing the uniformity of plasma cleaning. The electric actuator 133 drives the cleaning chamber 15 to continuously switch between horizontal and vertical positions, causing the material inside the cylindrical screen 153 to tumble and shake. The continuous switching of the cleaning chamber 15 increases the frequency and intensity of material tumbling inside the cylindrical screen 153, further improving the uniformity of plasma cleaning. When the cleaning chamber 15 switches from horizontal to vertical, the cleaning ring 23, through the counterweight 232, drives slide 221 and slip ring 231 towards slide 2. 222 moves, at which point the cleaning ring 23 pulls the flexible strip 22, causing the flexible strip 22 to twist along with the cylindrical screen 153. This twisting of the flexible strip 22 ensures the material is evenly distributed on the side wall of the slide 222, improving the uniformity of the plasma cleaning. When the cleaning chamber 15 switches from vertical to horizontal, the spring 212 is released, and the cleaning ring 23 drives the slide 221 and the sliding ring 231 back to their original positions. As the slide 221 returns to its original position, it pulls the flexible strip 22, causing the flexible strip 22 to move the material rapidly. This movement of the flexible strip 22 ensures the material is quickly and evenly distributed inside the cylindrical screen 153, improving the uniformity and efficiency of the plasma cleaning. At this point, the cleaning ring 23 reverses direction due to the pull of the torsion spring and the flexible strip 22.The cleaning ring 23 reverses during its return to its original position, cleaning the inner wall of the cylindrical screen 153. This allows dust to be discharged from the side walls of the cylindrical screen 153, preventing clogging and improving the cleanliness of the screen's interior.
