Description

Technical Field

[0001] This invention relates to the field of anode carbon block cleaning technology, specifically to a dual-station anode carbon block cleaning system. Background Technology

[0002] After the anode carbon blocks are roasted, they need to enter the cleaning line to clean the surface of the carbon blocks. Currently, the cleaning of anode carbon blocks and the collection of waste are mainly done manually, which is inefficient and the cleaning effect cannot be guaranteed to be consistent, which seriously affects the cleaning efficiency of anode carbon blocks.

[0003] To achieve automated cleaning of carbon blocks, a Chinese utility model patent document with authorization announcement number CN208495069U discloses an anode carbon block cleaning machine, which includes a carbon block long side and top cleaning component, a carbon block bottom cleaning component, a carbon block short side and groove cleaning component, and a probe hole cleaning component, etc. Through the above-mentioned components, the overall cleaning operation of the outer surface of the carbon block is carried out, thereby realizing the automated operation of carbon block cleaning.

[0004] While the aforementioned cleaning machine can automate the removal of deposits from the surface of charcoal blocks, it still suffers from the following problems:

[0005] (1) The cleaning machine described above is carried out in the manner of cleaning the long side and top, bottom, short side and carbon holes. The overall cleaning line uses multiple workstations for cleaning. The overall layout structure is long and cumbersome. Multiple workstations need to be set up to clean the surface of the carbon blocks. It cannot achieve integrated, fast and automated cleaning operation. It occupies a large area and causes inconvenience to environmental protection, cleaning monitoring and cleaning control in the factory area.

[0006] (2) In addition to the main body such as the side walls, upper and lower end faces, and the inside of the charcoal bowl, there are also some edge positions such as the bottom edge, top edge, and the circumferential diameter change position of the top protrusion of the charcoal block. These edge positions are not equipped with corresponding cleaning components for cleaning, which will result in the presence of residues at the aforementioned edge positions after cleaning, requiring additional workstations for scraping and cleaning. Summary of the Invention

[0007] The purpose of this invention is to provide a dual-station anode carbon block cleaning system to solve the problems of existing anode carbon block cleaning machines being unable to completely clean carbon blocks and having an unreasonable structural layout.

[0008] To solve the above problems, the dual-station anode carbon block cleaning system involved in this invention adopts the following technical solution:

[0009] The dual-station anode carbon block cleaning system includes a conveyor line, with several cleaning stations arranged along the conveying direction on at least one side of the conveyor line, which are in sequence a bottom cleaning device, a large surface cleaning station and a small surface cleaning station, and a visual positioning device is arranged above the conveyor line.

[0010] The conveyor line includes: two chain plates extending along the conveying direction, the two chain plates being arranged side by side with intervals, and several rollers arranged side by side with intervals along the conveying direction between the two chain plates, the rollers being equipped with a reduction motor;

[0011] The bottom cleaning device includes: a bottom surface cleaning mechanism and a bottom edge cleaning mechanism arranged at the entrance of the conveyor line. The bottom surface cleaning mechanism includes a horizontal scraper arranged between two adjacent rollers of the conveyor line, and a bottom surface cleaning support frame supported below the horizontal scraper. The bottom edge cleaning mechanism includes a bottom edge oblique scraper arranged between two adjacent rollers.

[0012] The large surface cleaning station includes: a large station clamping device arranged at the bottom of the conveyor line, a large station robot arranged on one side of the conveyor line, a large surface cleaning tool installed at the output position of the large station robot, the large surface cleaning tool including a rotary seat, a cutter head connected to the rotary seat, a flat scraping cutter head and an edge scraping cutter head fixed on the cutter head, and a large station drive motor for driving the cleaning tool to rotate on the rotary seat.

[0013] The small surface cleaning station includes: a small station clamping device arranged on the conveyor line, a small station robot arranged on one side of the conveyor line, and a small surface cleaning cutter installed on the output part of the small station robot. The small surface cleaning cutter includes a connecting seat, and a cleaning head, a sweeping head and an air nozzle are rotatably mounted on the connecting seat. The cleaning head is used to scrape the inside of the charcoal bowl, and the sweeping head is used to grind the top diameter change position of the charcoal block.

[0014] Furthermore, the bottom edge cleaning mechanism and the bottom surface cleaning mechanism are arranged in a staggered manner along the conveying direction.

[0015] Furthermore, both the bottom edge cleaning mechanism and the bottom surface cleaning mechanism are equipped with floating springs for applying elastic support to the corresponding horizontal scraper and bottom edge oblique scraper.

[0016] Furthermore, a centering guide structure is arranged on both sides of the inlet end of the conveyor line. The centering guide structure includes guide plates arranged on both sides of the conveyor belt. The diameter of the guide plates gradually decreases along the conveying direction to achieve centering guidance.

[0017] Furthermore, the small station cleaning tool has two or more cleaning heads and sweeping heads, and one of the cleaning heads and sweeping heads is selected and rotatedly assembled with the connecting seat.

[0018] Furthermore, the large station clamping device includes a lifting mechanism located at the bottom of the conveyor line and a lifting clamping plate connected to the top of the lifting mechanism. The lifting clamping plate is arranged between two adjacent rollers to lift and fix the carbon block upwards. The small station clamping device includes side clamping plates located on both sides of the conveyor line. The side clamping plates are also equipped with clamping drive cylinders.

[0019] Furthermore, the cleaning system also includes a manual final inspection station located downstream of the small surface cleaning station.

[0020] Furthermore, the cleaning system also includes dust removal devices arranged on both sides of the large surface cleaning station and the small surface cleaning station on the conveyor line. The dust removal devices include negative pressure hoods arranged on both sides of the conveyor line, and bag filters are connected to the outside of the hoods.

[0021] Furthermore, the cleaning system also includes a protective frame erected above the conveyor line and each cleaning station, with a visual positioning device arranged on the top of the protective frame; an inspection channel for personnel to conduct inspections is arranged on one side of the protective frame.

[0022] Furthermore, the cleaning system also includes a control host, which is signal-connected to a vision detection device to obtain position signals of various structures of the carbon block; the control host is also control-connected to the large station robot and the small station robot to control them to work separately.

[0023] The beneficial effects of this invention are as follows: In actual cleaning, when the anode carbon block enters the conveyor belt, the bottom surface and bottom edge of the carbon block are cleaned online through the bottom cleaning device. After entering the large surface cleaning station, the bottom of the carbon block is supported and fixed by the large station clamping mechanism. Then, the large station robot works, driving the flat scraper to scrape the four side walls, top wall, vertical edges, and horizontal edges of the carbon block, achieving effective cleaning of the main surface of the carbon block. Afterwards, the small station robot works, driving the cleaning head into the carbon bowl to scrape, and blowing the attached material out of the carbon bowl through the air nozzle. Then, the diameter change position of the upper protrusion of the carbon block is effectively ground by the cleaning head.

[0024] The aforementioned bottom cleaning device, large surface cleaning station, and small surface cleaning station enable effective scraping and cleaning of the main surface of the charcoal block, the charcoal bowl, as well as the edges, protrusions, and diameter-changing positions. The cleaning is thorough and highly efficient. The bottom cleaning device, in conjunction with two robots at two stations, can effectively clean all areas of the charcoal block. During cleaning, a self-positioning device detects the position of the charcoal block, and the robot controls the scraping angle and range of the scraper, ensuring precise control and fully automated cleaning. The compact structure allows for all cleaning to be completed via a single straight conveyor line, eliminating the need for flipping or rotating the charcoal block. The overall design is compact and highly integrated. Attached Figure Description

[0056] To make the technical objectives, technical solutions, and beneficial effects of the present invention clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention; that is, the described embodiments are merely some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0057] The existing structure of anode carbon blocks is as follows Figure 1 As shown, the carbon block 9 is a rectangular block structure with an upward protrusion 91 on the top. The edge of the protrusion 91 gradually shrinks inward to form a diameter change position 94. Several carbon bowls 92 are provided on the upper surface of the protrusion 91. The edges of the carbon bowls 92, the side walls 93 of the carbon block 9, and the edges 95 between the bottom wall and the edges of the bottom wall all have chamfered or rounded structures. In order to achieve automated and effective cleaning of various positions of the anode carbon block, the applicant has specially designed the following cleaning system.

[0058] Specific embodiments of the dual-station anode carbon block cleaning system involved in this invention are as follows: Figure 2-4 As shown, it includes a conveyor line 1 for installation in the factory building. A protective frame 2 is provided on the top of the conveyor line 1. The conveyor line 1 is defined to convey goods in a forward-to-back direction. The protective frame 2 spans the left and right sides of the conveyor line 1. At the same time, an inspection channel 21 is provided on the protective frame 2. The inspection channel 21 allows staff to easily observe the internal cleaning process.

[0059] Several cleaning stations are arranged sequentially along one side of conveyor line 1, namely, bottom cleaning device 3, large surface cleaning station 4, small surface cleaning station 5, and manual final inspection station 6. A vision positioning device 7 is also arranged on the protective frame 2 directly above conveyor line 1. A pushing mechanism 13 is arranged at the front end of conveyor line 1 to facilitate pushing the anode carbon blocks onto the conveyor line 1. After sequential cleaning at each station, the carbon blocks are automatically and completely cleaned.

[0060] The structure of conveyor line 1 is shown in the figure. It includes two chain plates 11 extending in the front-to-back direction. The two chain plates 11 are arranged side by side at intervals in the left-to-right direction. At the same time, several rollers 12 are arranged between the two chain plates 11. Each roller 12 is equipped with a geared motor. The geared motor controls each roller 12 to rotate in the same direction, thereby realizing the smooth conveying of carbon blocks from front to back.

[0061] After the anode carbon block enters conveyor line 1, a centering guide structure is arranged at the entrance of conveyor line 1 to ensure rapid and accurate positioning for subsequent conveying. This centering guide structure includes guide plates 14 on both sides of the conveyor belt. The diameter of the guide plates 14 gradually decreases along the conveying direction to achieve centering guidance. The two guide plates 14 have identical structures and are symmetrically fixed to the chain plates 11 of conveyor line 1 with the left and right center positions of conveyor line 1 as the axis. When the anode carbon block enters conveyor line 1, it is centered by the guide plates 14, facilitating the subsequent scraping and cleaning operations of the ground cleaning device.

[0062] After being guided, the charcoal blocks first enter the station where the bottom cleaning device 3 is located. The structure of the bottom cleaning device 3 is shown in the figure. It includes a bottom surface cleaning mechanism 3-1 and a bottom edge cleaning mechanism 3-2 arranged at the entrance of the conveyor line 1. The bottom surface cleaning mechanism 3-1 is used to scrape the bottom wall of the charcoal block, and the bottom edge cleaning mechanism 3-2 is used to scrape the two sides of the charcoal block. Preferably, in order to ensure the integrity of the cleaning, there are two or more bottom surface cleaning mechanisms 3-1, which are arranged at intervals in the front-back direction. At the same time, the bottom edge cleaning mechanism 3-2 is arranged between two adjacent bottom surface cleaning mechanisms 3-1.

[0063] The bottom cleaning mechanism 3-1 includes a horizontal scraper arranged between two adjacent rollers 12 on the conveyor line 1, and a bottom cleaning support frame supported below the horizontal scraper. Specifically, the bottom cleaning device includes a cutter shaft 3-1-1 arranged between two adjacent rollers 12 on the conveyor line 1, with the axis of the cutter shaft 3-1-1 parallel to the axis of the rollers 12. The bottom cleaning device also includes two bottom cleaning support frames 3-1-4 arranged at both ends of the cutter shaft 3-1-1. The cutter shaft 3-1-1 is rotatably mounted on the two bottom cleaning support frames 3-1-4. Specifically, bearing seats 3-1-5 are respectively provided on the two bottom cleaning support frames 3-1-4. The two bearing seats 3-1-5 are coaxially arranged. One end of the cutter shaft 3-1-1 is rotatably assembled with the bearing seat 3-1-5 of one bottom cleaning support frame 3-1-4, and the other end is rotatably assembled with the bearing seat 3-1-5 on the other bottom cleaning support frame 3-1-4. The cutter shaft 3-1-1 is a rod-shaped straight shaft, on which a horizontal scraper 3-1-2 is arranged. The horizontal scraper 3-1-2 is a long strip-shaped blade extending horizontally perpendicular to the conveying direction. A geared motor 3-1-6 for driving the rotation of the cutter shaft 3-1-1 is also connected to one of the bottom cleaning support frames 3-1-4. The rotation direction of the cutter shaft 3-1-1 is opposite to the conveying direction of the charcoal block. The top of the rotating outer contour of the horizontal scraper 3-1-2 is not lower than the upper surface of the roller 12, so as to be in contact with the bottom surface of the charcoal block and scrape it in the opposite direction. The geared motor 3-1-6 controls the reverse rotation of the cutter shaft 3-1-1, and the blade on the cutter shaft 3-1-1 is driven to swing in the opposite direction. The vertical height limitation of the cutter shaft 3-1-1 ensures that the blade is in contact with the bottom surface of the charcoal block, thereby achieving effective scraping of the bottom surface of the charcoal block by the blade. To support the cutter shaft 3-1-1 and ensure the scraping length of the blade is not less than the bottom width of the carbon block, two bottom cleaning support frames 3-1-4 are located on the outer sides of the left and right sides of conveyor line 1, respectively. The bottom cleaning support frames 3-1-4 are fixed to the ground by a base plate, and support columns ensure that the height of the bottom cleaning support frames 3-1-4 is basically matched with the height of the roller 12. To achieve a tight fit between the blade and the bottom surface of the carbon block, a floating spring (compression spring) is provided between the bottom cleaning support frame 3-1-4 and the cutter shaft 3-1-1 to drive the cutter shaft 3-1-1 upwards and bring the blade into contact with the bottom surface of the carbon block. Driven by a compression spring, the cutter shaft 3-1-1 always maintains an upward moving force. When the charcoal block is conveyed above the cutter shaft 3-1-1, due to the weight of the charcoal block, the bottom surface of the charcoal block presses down on the cutter shaft 3-1-1, thereby enabling the cutter shaft 3-1-1 to have a pre-pressure that adheres to the bottom surface of the charcoal block. When the cutter shaft 3-1-1 rotates in the opposite direction, the adhering substances on the bottom surface of the charcoal block can be effectively cleaned, and the bottom surface of the charcoal block can be flattened.

[0064] To achieve continuous scraping, there are two or more horizontal scrapers 3-1-2, evenly spaced circumferentially around the cutter shaft 3-1-1. Specifically, each horizontal scraper 3-1-2 includes two or more blades, evenly spaced along the axial direction of the cutter shaft 3-1-1. The blades in adjacent horizontal scrapers 3-1-2 are staggered relative to each other along the axial direction of the cutter shaft 3-1-1. The multi-blade horizontal scraper 3-1-2 effectively saves on cost while ensuring effective scraping of all positions on the bottom surface of the carbon block in the width direction through staggered arrangement, avoiding dead corners or unscraped areas. Furthermore, the blades can be adaptively replaced according to actual blade wear, further saving costs. For blade installation, the cutter shaft 3-1-1 has a groove extending parallel to its axis. The blades of the horizontal scraper 3-1-2 are sequentially arranged and fixed within the groove, secured by screws.

[0065] The bottom edge cleaning mechanism 3-2 includes a bottom edge oblique scraper 3-2-3 arranged between two adjacent rollers 12; specifically, the bottom edge cleaning device 3-2 includes two cleaning frames 3-2-1 arranged between two adjacent rollers 12. The two cleaning frames 3-2-1 are respectively installed on the chain plates 11 on the left and right sides of the conveyor line 1, and the two cleaning frames 3-2-1 are arranged horizontally and symmetrically at intervals perpendicular to the conveying direction. Taking one of the cleaning racks 3-2-1 as an example, as shown in the figure, the cleaning rack 3-2-1 is connected to a knife holder 3-2-2. The knife holder 3-2-2 has a bottom-edge oblique scraper 3-2-3 arranged facing the bottom edge of the charcoal block. The blade cross-section of the bottom-edge oblique scraper 3-2-3 is consistent with the bottom edge cross-section of the charcoal block. The bottom surface height of the bottom-edge oblique scraper 3-2-3 is lower than the upper surface height of the conveyor line 1, and the top surface height of the bottom-edge oblique scraper 3-2-3 is higher than the upper surface height of the conveyor line 1. An elastic element is connected between the bottom-edge oblique scraper 3-2-3 and the knife holder 3-2-2 to apply an inward force to the bottom-edge oblique scraper 3-2-3 to fit against the bottom surface of the charcoal block. There is an anti-detachment structure between the bottom-edge oblique scraper 3-2-3 and the knife holder 3-2-2. In actual operation, the bottom edge scrapers 3-2-3 on both sides are pushed by the floating spring and make close contact with the bottom edge of the carbon block. As the carbon block is conveyed forward, the bottom edge scrapers 3-2-3 can effectively clean the material attached to the bottom edge without stopping the machine.

[0066] Specifically, to ensure a proper fit between the bottom edge scraper 3-2-3 and the bottom edge of the charcoal block, in this embodiment, when the bottom edge of the charcoal block has rounded corners, the bottom edge scraper 3-2-3 uses an arc-shaped blade; when the bottom edge of the charcoal block has a chamfer, the bottom edge scraper 3-2-3 uses a beveled blade. The bottom surface of the bottom edge scraper 3-2-3 is lower than the upper surface of the conveyor line 1, while the top surface of the bottom edge scraper 3-2-3 is higher than the upper surface of the conveyor line 1. This is primarily to ensure that the bottom edge scraper 3-2-3 can fit along all paths of the beveled edge of the bottom edge of the charcoal block during the charcoal block conveying process, guaranteeing the completeness of the cleaning.

[0067] In a preferred embodiment, at least one cleaning frame 3-2-1 is provided with an adjustment mechanism for adjusting the relative distance between the two blade holders 3-2-2. Specifically, the two cleaning frames 3-2-1 are defined as the left cleaning frame 3-2-1 and the right cleaning frame 3-2-1. In this embodiment, the adjustment mechanism is located on the left cleaning frame 3-2-1. Adjusting the adjustment mechanism adjusts the distance between the two bottom edge oblique scrapers 3-2-3, thereby achieving the ability to adapt to the bottom edge distance of different charcoal blocks and meet the uniform cleaning requirements of charcoal blocks of different specifications. To facilitate the installation of the bottom-edge oblique scraper 3-2-3, in this embodiment, the scraper holder 3-2-2 includes a mounting block 3-2-31. The inner surface of the mounting block 3-2-31 has an outwardly extending vertically extending groove 3-2-311. The bottom-edge oblique scraper 3-2-3 is movably assembled within the groove 3-2-311. The elastic element is a floating spring mounted between the bottom wall of the groove 3-2-311 and the bottom-edge oblique scraper 3-2-3; in this embodiment, it is a compression spring. Since the bottom-edge oblique scraper 3-2-3 has a plate-type blade structure with a cutting edge on its inner side, the guide groove design allows for floating assembly of the bottom-edge oblique scraper 3-2-3 in the left-right direction.

[0068] After passing through the bottom cleaning device 3, the charcoal block enters the large surface cleaning station 4. In this embodiment, the large surface cleaning station 4 includes a large station clamping device 4-2 arranged at the bottom of the conveyor line 1 and a large station robot 4-1 arranged on one side of the conveyor line 1. A large surface cleaning cutter 4-1-2 is installed at the output position of the large station robot 4-1. The large surface cleaning cutter 4-1-2 includes a rotary seat 4-1-3. A cutter head 4-1-4 is connected to the rotary seat 4-1-3. A flat scraping cutter head 4-1-5 and an edge scraping cutter head 4-1-6 are fixed on the cutter head 4-1-4. A large station drive motor 4-1-23 for driving the cleaning cutter to rotate is also configured on the rotary seat 4-1-3.

[0069] The structure of the large-scale robot 4-1 is shown in the figure. The large-scale robot 4-1 includes a robotic arm 4-1-1 and a cleaning unit connected to the robotic arm 4-1-1. The cleaning unit includes a cleaning seat 4-1-21, which is a cylindrical structure with mounting holes extending forward and backward along its axis. A main shaft 4-1-22 is rotatably mounted within the mounting holes. One end of the main shaft 4-1-22 is connected to a cleaning tool 4-1-2, and the other end is connected to a large-scale drive motor 4-1-23 fixed on the cleaning seat 4-1-21. The large-scale drive motor 4-1-23 drives the main shaft 4-1-22 to rotate, thereby driving the cleaning tool 4-1-2 to rotate, achieving scraping operation of the tool head on the working surface. In this embodiment, the large-scale drive motor 4-1-23 is a variable frequency servo motor, which can effectively control the rotational speed of the cleaning tool 4-1-2. The cleaning tool 4-1-2 includes a rotary seat 4-1-3 coaxially connected to the spindle 4-1-22. The rotation axis of the rotary seat 4-1-3 is defined to extend in the front-back direction. A cutter head 4-1-4 is coaxially connected to the front end of the rotary seat 4-1-3. Two or more flat scraping heads 4-1-5 for scraping the surface of the carbon block are fixed at the front end of the cutter head 4-1-4. The flat scraping heads are evenly distributed around the circumference of the cutter head. Edge scraping heads 4-1-6 for scraping the corners of the carbon block are connected to the rotary seat 4-1-3. There are two or more edge scraping heads 4-1-6, which are evenly distributed around the circumference of the rotary seat 4-1-3. In a preferred embodiment, the flat scraping head 4-1-5 adopts a long, straight blade to scrape the flat surface of the carbon block's end face and sides. The edge scraping head 4-1-6 adopts a crescent-shaped arc-shaped blade to accommodate the rounded corners of the carbon block. Of course, depending on the actual corner shape, such as chamfers, a three-sided flared cross-section can be used; no specific limitation is made. The flat scraping head 4-1-5 effectively scrapes the large flat surface of the carbon block, and then the edge scraping head 4-1-6 effectively scrapes the corners of the carbon block, such as vertical and horizontal edges. Thus, a single robotic arm 4-1-1 controls the cleaning unit to perform integrated cleaning of multiple processes, achieving thorough cleaning of the carbon block's surface and avoiding uncleaned areas and cleaning dead zones.

[0070] The structure of the large station clamping device 4-2 is shown in the figure. Since it is necessary to clean the large surface of the side wall and top wall of the carbon block, the cleaning of the carbon block at this station needs to be carried out by bottom lifting. The large station clamping device 4-2 includes a lifting mechanism 4-2-1 set at the bottom of the conveyor line 1 and a lifting clamping plate 4-2-2 connected to the top of the lifting mechanism 4-2-1. The lifting clamping plate 4-2-2 is arranged between two adjacent rollers 12 to lift and fix the carbon block.

[0071] Specifically, the aforementioned lifting mechanism 4-2-1 includes multiple lifting cylinders arranged side by side at intervals. The lifting cylinders are arranged at intervals along the front-to-back direction. Each lifting cylinder is equipped with a lifting clamping plate 4-2-2 on its top. The lifting clamping plate 4-2-2 is used to support the bottom of the charcoal block. When the charcoal block moves above the lifting mechanism 4-2-1, the lifting cylinder at the corresponding position is controlled to rise according to the front-to-back length of the charcoal block, thereby lifting the charcoal block as a whole and preventing the charcoal block from continuing to be conveyed backward with the conveyor line 1, thus achieving the positioning of the charcoal block.

[0072] After passing through the large surface cleaning station 4, the charcoal block enters the small surface cleaning station 5. The small surface cleaning station 5 includes a small station clamping device 5-2 arranged on the conveyor line 1 and a small station robot 5-1 arranged on one side of the conveyor line 1. The output end of the small station robot 5-1 is equipped with a small surface cleaning cutter 5-1-2. The small surface cleaning cutter 5-1-2 includes a connecting seat 5-1-4. A cleaning cutter head 5-1-5, a cleaning head 5-1-6, and an air nozzle 5-1-7 are rotatably mounted on the connecting seat 5-1-4. The cleaning cutter head is used to scrape the inside of the charcoal bowl, and the cleaning head is used to grind the top diameter change position of the charcoal block.

[0073] The structure of the station robot 5-1 is shown in the figure. The station robot 5-1 includes a manipulator 5-1-1 and a small surface cleaning cutter 5-1-2 connected to the manipulator 5-1-1. The small surface cleaning cutter 5-1-2 includes a connecting seat 5-1-4. A cleaning head 5-1-5 and a sweeping head 5-1-6 are rotatably mounted on the connecting seat 5-1-4. An air nozzle 5-1-7 is also fixed on the connecting seat 5-1-4. The cleaning head 5-1-5, the sweeping head 5-1-6 and the air nozzle 5-1-7 are arranged at intervals around the periphery of the connecting seat 5-1-4. The connecting seat 5-1-4 is also provided with a drive mechanism to drive the cleaning head 5-1-5 and the sweeping head 5-1-6 to rotate respectively, and an air blowing pipe connected to the air nozzle 5-1-7. Preferably, for ease of control, the connecting seat 5-1-4 has three or more connecting parts on its periphery, and the cleaning head 5-1-5, the cleaning head 5-1-6, and the air nozzle 5-1-7 are respectively connected to each connecting part. The connecting seat 5-1-4 is a three-way cylindrical structure with three connecting shafts 5-1-41. Two of the three connecting shafts 5-1-41 have the same axis and extend in opposite directions, while the axis of the third connecting shaft 5-1-41 is arranged perpendicular to the aforementioned axes. Each connecting shaft 5-1-41 constitutes one of the connecting parts.

[0074] To drive each connector, in this embodiment, the drive mechanism includes hydraulic motors 5-1-43 connected to each connector. The output shaft of each hydraulic motor 5-1-43 is connected to a cleaning blade 5-1-5 and a sweeping head 5-1-6 respectively. In actual operation, the connector 5-1-4 rotates the corresponding working head to a set angle, and then the hydraulic motors 5-1-43 rotate, driving the corresponding cleaning blade 5-1-5 or sweeping head 5-1-6 to rotate, thus performing cleaning work on the surface of the charcoal block and charcoal bowl.

[0075] There are two cleaning heads 5-1-5, each connected to one of the two connecting shafts 5-1-41. A cleaning head 5-1-6 is connected to the other connecting shaft 5-1-41. An air nozzle 5-1-7 is attached to the side wall of the connecting seat 5-1-4. The four working heads are arranged in a cross shape, achieving a compact installation while effectively avoiding mutual interference. A mounting ring extends from the side wall of the connecting seat 5-1-4, and a blowing frame 5-1-8 is connected to the mounting ring. The blowing frame 5-1-8 includes two L-shaped rods. The vertical sides of the L-shaped rods are perpendicular to the plane containing the axes of the three connecting shafts 5-1-41, while the horizontal sides extend horizontally. The air nozzle 5-1-7 is fixed to the horizontal side of the blowing frame 5-1-8 and extends downwards. The upper end of the air nozzle 5-1-7 is used to connect to the air blowing pipe, thereby spraying high-pressure gas downwards through the air nozzle 5-1-7 to effectively remove the deposits on the surface of the charcoal bowl and charcoal blocks. Both cleaning heads 5-1-5 include a cutter disc rotatably mounted on a corresponding connecting shaft 5-1-41. Several blades are arranged at intervals around the end face of the cutter disc along its axis of rotation. The cutting edges of the blades protrude outwards along the axis of the cutter disc. A brush is also connected to the cutter disc, and the extension length of the brush is not less than the extension length of the blades. Multiple cleaning heads 5-1-6 are included, each comprising a bracket 5-1-61 and a brush 5-1-62 filled on the bracket 5-1-61. The cross-sectional shape of each bracket 5-1-61 is different. One of the cleaning heads 5-1-6 is selected and anti-rotated with the output shaft of the corresponding hydraulic motor 5-1-43 on the connecting seat 5-1-4. Three types of cleaning heads 5-1-6 are designed to adapt to different types of cleaning operations with varying diameters.

[0076] In actual use, the angle of the connecting seat 5-1-4 is adjusted by the robotic arm 5-1-1, and the cleaning head 5-1-5 of the appropriate size is rotated to a position coaxial with the charcoal bowl. Then, the hydraulic motor 5-1-43 operates, and the cleaning head 5-1-5 extends downward into the charcoal bowl, scraping and cleaning the attached materials at the same time to prevent them from accumulating inside. After cleaning, the attached materials in each charcoal bowl are effectively blown out by the air nozzle 5-1-7. Finally, the appropriate cleaning head 5-1-6 is adjusted to effectively scrape the diameter-changing position of the protrusion on the upper surface of the charcoal block. Afterward, the attached materials are blown away by the air nozzle 5-1-7 again, thus achieving effective cleaning of the upper part of the charcoal block and the inside of the charcoal bowl.

[0077] The structure of the small station clamping device 5-2 is shown in the figure. It includes side clamping plates 5-2-1 set on both sides of the conveyor line 1. The side clamping plates 5-2-1 are also equipped with clamping drive cylinders 5-2-2. One side clamping plate 5-2-1 is movably mounted on the base of the small station robot 5-1, and the other side clamping plate 5-2-1 is fixed to the ground by the base. The two side clamping plates 5-2-1 are arranged at the same height. Each side clamping plate 5-2-1 is equipped with a clamping drive cylinder 5-2-2. In actual operation, the clamping drive cylinder 5-2-2 works to drive the two side clamping plates 5-2-1 to move closer to each other in sync, thereby clamping and fixing the carbon block.

[0078] After the charcoal blocks pass through the small surface cleaning station 5, they are output from the conveyor line 1 and pass through the manual intermediate station 6. The manual intermediate station 6 includes a support box 6-1 and a conveyor roller 6-2 arranged on the support box 6-1. The worker stands on one side of the conveyor roller 6-2 and uses the appropriate tools to inspect the surface of the charcoal blocks and finally wipe and clean them.

[0079] To achieve accurate identification of the position of the carbon block in the large surface cleaning station 4 and the small surface cleaning station 5, a visual positioning device 7 is used to detect the position signal of the carbon block in real time. The cleaning system also includes a control host, which is connected to the visual detection device to obtain the position signals of each structure of the carbon block. The control host is connected to the large station robot and the small station robot to control them to work separately.

[0080] To ensure dust collection at each workstation and maintain a clean environment within the system, the cleaning system also includes dust collection devices 8 located on both sides of the large surface cleaning station 4 and the small surface cleaning station 5 along the conveyor line 1. Each dust collection device 8 consists of negative pressure hoods 8-1 positioned on both sides of the conveyor line 1, with bag filters connected to the outer side of the hoods. During normal cleaning, external negative pressure fans create negative pressure at each workstation, causing any airborne particles to pass through the negative pressure hoods 8-1 and be collected by the bag filters.

[0081] During normal operation, the bottom surface and bottom edge of the charcoal block are cleaned online through the bottom cleaning device 3. After entering the large surface cleaning station 4, the bottom of the charcoal block is supported and fixed by the large station clamping mechanism 4-2. Then, the large station robot 4-1 works, driving the flat scraper to scrape the four side walls, top wall, vertical edges, and horizontal edges of the charcoal block, achieving effective cleaning of the main surface of the charcoal block. After that, the small station robot 5-1 works, driving the cleaning head into the charcoal bowl to scrape, and blowing the attached material out of the charcoal bowl through the air nozzle. Then, the diameter change position of the upper protrusion of the charcoal block is effectively ground by the cleaning head. Finally, the cleaning process is completed by manual final inspection.

[0082] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of the present invention. Any equivalent substitutions, modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
