Description

Technical Field

[0001] The invention relates to the technical field of anode carbon block cleaning, and in particular to a double-station anode carbon block cleaning system. Background Art

[0002] After the anode carbon blocks are roasted, they need to enter the cleaning line to clean the attachments on 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 the anode carbon blocks.

[0003] In order to realize the 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 carbon block long side and top cleaning components, carbon block bottom cleaning components, carbon block short side and groove cleaning components and probe hole cleaning components, etc. Through the overall cleaning operation of the outer surface of the carbon block by the above-mentioned components, the automated cleaning of the carbon blocks is realized.

[0005] (1) The above-mentioned cleaning machine operates in the manner of long side and top surface, bottom surface, short side surface, and carbon hole. The overall cleaning line adopts multiple stations for cleaning. The overall layout structure is lengthy and multiple stations need to be set up to clean the surface of the carbon block. It is impossible to realize integrated rapid automated cleaning operation. It occupies a large area and causes inconvenience to the environmental protection in the factory area and the cleaning monitoring and cleaning control processes.

[0006] (2) In addition to the main body of the carbon block, such as the side walls, upper and lower end faces, and the inside of the carbon 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 carbon block. However, these edge positions are not equipped with corresponding cleaning components for cleaning.

[0056] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the technical solution of the present invention is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0057] The structure of the existing anode carbon block is as follows Figure 1 As shown, the carbon block 9 is a rectangular block structure as a whole, with an upwardly protruding boss 91 on the top, the edge position of the boss 91 gradually retracts inward to form a variable diameter position 94, and a plurality of carbon bowls 92 are provided on the upper end surface of the boss 91. The edges of the carbon bowls 92, the side walls 93 of the carbon block 9, and the edges 95 between the bottom walls all have chamfered or rounded structures. In order to realize automatic and effective cleaning of various positions of the anode carbon block, the applicant specially designed the following cleaning system.

[0058] The specific embodiment of the double-station anode carbon block cleaning system involved in the present invention is as follows: Figure 2-4 As shown, it includes a conveyor line 1 for arrangement in a factory building. A protective frame 2 is provided on the top cover of the conveyor line 1. The conveyor line 1 is defined to be transported in a direction from front to back. The protective frame 2 is spanned on the left and right sides of the conveyor line 1. At the same time, an inspection channel 21 is also provided on the protective frame 2, through which the staff can conveniently observe the internal cleaning process.

[0059] Several cleaning stations are arranged in sequence along the front-to-back direction on one side of the conveyor line 1, which are the bottom cleaning device 3, the large surface cleaning station 4, the small surface cleaning station 5, and the manual final inspection station 6. At the same time, a visual positioning device 7 is arranged on the protective frame 2 just above the conveyor line 1. A pushing mechanism 13 is arranged at the front end of the conveyor line 1 to facilitate pushing the anode carbon block onto the conveyor line 1, and then through the cleaning of each station in sequence, the automatic and complete cleaning operation of the carbon block is realized.

[0060] The structure of the conveyor line 1 is shown in the figure, which 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, a plurality of rollers 12 are arranged between the two chain plates 11. The rollers 12 are equipped with reduction motors. The reduction motors control the rollers 12 to rotate in the same direction, thereby realizing smooth transportation of carbon blocks from front to back.

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

[0062] After being guided, the carbon block first enters the workstation where the bottom cleaning device 3 is located. The structure of the bottom cleaning device 3 is shown in the figure, which 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, wherein the bottom surface cleaning mechanism 3-1 is used to scrape the bottom wall of the carbon block, and the bottom edge cleaning mechanism 3-2 is used to scrape the two side edges of the carbon block. Preferably, in order to ensure the integrity of the cleaning, there are more than two bottom surface cleaning mechanisms 3-1, which are arranged at intervals in the front and rear directions, and the bottom edge cleaning mechanism 3-2 is arranged between two adjacent bottom surface cleaning mechanisms 3-1.

[0063] Among them, the bottom surface cleaning mechanism 3-1 includes a horizontal scraper arranged between two adjacent rollers 12 of the conveyor line 1, and also includes a bottom surface cleaning support frame supported below the horizontal scraper; specifically, the bottom surface cleaning device includes a knife shaft 3-1-1 arranged between two adjacent rollers 12 of the conveyor line 1, and the axis of the knife shaft 3-1-1 is parallel to the axis of the roller 12. The bottom surface cleaning device also includes two bottom surface cleaning support frames 3-1-4 arranged at both ends of the knife shaft 3-1-1, and the knife shaft 3-1-1 is rotatably mounted on the two bottom surface cleaning support frames 3-1-4. Specifically, bearing seats 3-1-5 are respectively provided on the two bottom surface cleaning support frames 3-1-4, and the two bearing seats 3-1-5 are coaxially arranged. One end of the knife shaft 3-1-1 is rotatably assembled with the bearing seat 3-1-5 of one of the bottom surface cleaning support frames 3-1-4, and the other end is rotatably assembled with the bearing seat 3-1-5 on the other bottom surface cleaning support frame 3-1-4. The blade shaft 3-1-1 is a rod-shaped straight shaft, and a horizontal scraper 3-1-2 is arranged on the blade shaft 3-1-1. The horizontal scraper 3-1-2 is a long strip blade extending horizontally perpendicular to the conveying direction. A reduction motor 3-1-6 for driving the blade shaft 3-1-1 to rotate is also connected to one of the bottom surface cleaning support frames 3-1-4. The rotation direction of the blade shaft 3-1-1 is opposite to the conveying direction of the carbon block. The top of the rotating outer contour of the horizontal scraper 3-1-2 is not lower than the upper surface of the drum 12, so as to fit with the bottom surface of the carbon block and reversely scrape the carbon block. The reduction motor 3-1-6 is used to control the reverse rotation of the blade shaft 3-1-1, and the blade on the blade shaft 3-1-1 is driven to swing in the opposite direction. The blade is in contact with the bottom surface of the carbon block through the upper and lower height restrictions of the blade shaft 3-1-1, so that the bottom surface of the carbon block can be effectively scraped by the blade. In order to support the blade shaft 3-1-1 and make the scraping length of the blade not less than the bottom width of the carbon block, two bottom cleaning support frames 3-1-4 are respectively located on the outside of the left and right sides of the conveyor line 1. The bottom cleaning support frame 3-1-4 is fixed to the ground through a bottom plate, and the height of the bottom cleaning support frame 3-1-4 is basically matched with the height of the roller 12 through a support column. In order to achieve a close fit between the blade and the bottom surface of the carbon block, a floating spring is provided between the bottom cleaning support frame 3-1-4 and the blade shaft 3-1-1 to drive the blade shaft 3-1-1 to move upward to make the blade fit and contact the bottom surface of the carbon block. The floating spring is a compression spring. The knife shaft 3-1-1 is driven by the compression spring and always maintains an upward moving force. When the carbon block is transported to the top of the knife shaft 3-1-1, due to its heavy weight, the bottom surface of the carbon block presses the knife shaft 3-1-1 downward, so that the knife shaft 3-1-1 has a pre-pressure to fit the bottom surface of the carbon block upward. When the knife shaft 3-1-1 rotates in the opposite direction, the attachments on the bottom surface of the carbon block can be effectively cleaned and the bottom surface of the carbon block can be leveled.

[0064] In order to achieve continuous scraping, there are more than two horizontal scrapers 3-1-2, which are evenly spaced around the circumference of the blade shaft 3-1-1. Specifically, each of the horizontal scrapers 3-1-2 includes more than two blades, and each blade is evenly spaced along the axial direction of the blade shaft 3-1-1. The blades of two adjacent horizontal scrapers 3-1-2 are relatively staggered along the axial direction of the blade shaft 3-1-1. The horizontal scraper 3-1-2 composed of multiple blades can effectively save the cost of the horizontal scraper 3-1-2. At the same time, the staggered arrangement can effectively scrape each position in the width direction of the bottom surface of the carbon block, avoid dead corners or unscraped positions, and can adaptively replace the corresponding blade according to the actual blade wear, effectively saving costs. In order to achieve the installation of the blade, the blade shaft 3-1-1 is provided with a blade groove extending along the axis parallel to the blade shaft 3-1-1. The blades of the horizontal scraper 3-1-2 are arranged and fixed in the blade groove in sequence, and fixed by screwing.

[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, and 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 horizontally symmetrically arranged 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 tool holder 3-2-2, and the tool holder 3-2-2 has a bottom edge oblique scraper 3-2-3 arranged toward the bottom edge of the carbon block, the blade cross section of the bottom edge oblique scraper 3-2-3 is consistent with the bottom edge cross section of the carbon 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, and an elastic member is connected between the bottom edge oblique scraper 3-2-3 and the tool holder 3-2-2 to apply a force to the bottom edge scraper 3-2-3 to move inward to fit against the bottom surface of the carbon block; an anti-slip structure is provided between the bottom edge oblique scraper 3-2-3 and the tool holder 3-2-2. In actual operation, the bottom edge oblique scrapers 3-2-3 on both sides are pushed by the floating springs to closely contact the bottom edge of the carbon block. As the carbon block is conveyed forward, the bottom edge oblique scrapers 3-2-3 can effectively clean the edge attachments of the bottom edge without stopping the machine.

[0066] Specifically, in order to ensure that the bottom edge oblique scraper 3-2-3 fits the bottom edge of the carbon block, in this embodiment, when the bottom edge of the carbon block is provided with a rounded corner, the bottom edge oblique scraper 3-2-3 uses an arc blade, and when the bottom edge of the carbon block is provided with a chamfer, the bottom edge oblique scraper 3-2-3 uses a beveled blade. 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. This is mainly to ensure that the bottom edge oblique scraper 3-2-3 can fit all paths of the cross-sectional bevel of the bottom edge of the carbon block during the conveying process to ensure the integrity of its cleaning.

[0067] As a preferred embodiment, at least one cleaning rack 3-2-1 is provided with an adjustment mechanism for adjusting the relative spacing between the two blade racks 3-2-2. Specifically, the two cleaning racks 3-2-1 are defined as a left cleaning rack 3-2-1 and a right cleaning rack 3-2-1. In this embodiment, the adjustment mechanism is provided on the left cleaning rack 3-2-1. The adjustment mechanism is adjusted to adjust the spacing between the two bottom edge oblique scrapers 3-2-3, so as to adapt to the bottom edge spacing of different carbon blocks and meet the uniform cleaning of carbon blocks of different specifications. In order to realize the installation of the bottom edge bevel scraper 3-2-3, in this embodiment, the blade holder 3-2-2 includes a mounting block 3-2-31, the inner surface of the mounting block 3-2-31 is provided with a blade groove 3-2-311 extending up and down, the bottom edge bevel scraper 3-2-3 is movably assembled in the blade groove 3-2-311, and the elastic member is a floating spring mounted between the bottom wall of the blade groove 3-2-311 and the bottom edge bevel scraper 3-2-3, and in this embodiment, it is a compression spring. Since the bottom edge bevel scraper 3-2-3 is a plate blade structure with a blade formed on its inner side, the design of the guide groove can satisfy the floating assembly of the bottom edge bevel scraper 3-2-3 in the left and right directions.

[0068] After passing through the bottom cleaning device 3, the carbon 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 tool 4-1-2 is installed at the output position of the large station robot 4-1. The large surface cleaning tool 4-1-2 includes a rotating seat 4-1-3, and a knife disc 4-1-4 is connected to the rotating seat 4-1-3. A plane scraping head 4-1-5 and an edge scraping head 4-1-6 are fixed on the knife disc 4-1-4. The rotating seat 4-1-3 is also equipped with a large station drive motor 4-1-23 for driving the cleaning tool to rotate.

[0069] The structure of the large station robot 4-1 is shown in the figure. The large station robot 4-1 includes a manipulator 4-1-1 and a cleaning unit connected to the manipulator 4-1-1. The cleaning unit includes a cleaning seat 4-1-21. The cleaning seat 4-1-21 is a cylindrical structure as a whole, and has a mounting hole with an axis extending forward and backward; a spindle 4-1-22 is rotatably assembled in the mounting hole, one end of the spindle 4-1-22 is connected to a cleaning tool 4-1-2, and the other end is connected to a large station drive motor 4-1-23 fixed on the cleaning seat 4-1-21. The spindle 4-1-22 is driven to rotate by the large station drive motor 4-1-23, and then the cleaning tool 4-1-2 is driven to perform a rotary motion, so as to realize the scraping operation of the cutter head on the working surface. In this embodiment, the large station drive motor 4-1-23 adopts a variable frequency servo motor, which can effectively control the rotation speed of the cleaning tool 4-1-2. The cleaning tool 4-1-2 includes a swivel seat 4-1-3 coaxially connected to the main shaft 4-1-22, and the rotation axis of the swivel seat 4-1-3 is defined to extend in the front-to-back direction. The front end of the swivel seat 4-1-3 is coaxially connected to a cutter disc 4-1-4. The front end of the cutter disc 4-1-4 is fixed with two or more flat scraping heads 4-1-5 for scraping the surface of the carbon block. The flat scraping heads are evenly spaced along the circumference of the disc. The swivel seat 4-1-3 is connected to an edge scraping head 4-1-6 for scraping the corners of the carbon blocks. There are more than two edge scraping heads 4-1-6, which are evenly spaced around the circumference of the swivel seat 4-1-3. As a preferred embodiment, the plane scraping blade head 4-1-5 adopts a long straight blade head to scrape the flat surface of the end face and side face of the carbon block, while the edge scraping blade head 4-1-6 adopts a crescent-shaped curved blade head to adapt to the chamfered corners at the corners of the carbon block. Of course, it can also be based on the actual corner form, such as chamfering, and a three-straight-sided flared form and other cross-sections can be adopted without specific limitation. The plane scraping blade head 4-1-5 is used to effectively scrape the large flat surface of the carbon block, and then the edge scraping blade head 4-1-6 is used to effectively scrape the corner positions of the carbon block such as vertical edges and horizontal edges. In this way, a robot 4-1-1 can be used to control the cleaning unit to perform integrated cleaning of multiple processes, so as to achieve thorough cleaning of the surface of the carbon block, avoid uncleaned areas, and avoid cleaning dead corners.

[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 the top wall of the carbon block, the cleaning of the carbon block at this workstation needs to be carried out by bottom jacking. The large station clamping device 4-2 includes a jacking mechanism 4-2-1 arranged at the bottom of the conveyor line 1 and a lifting and clamping plate 4-2-2 connected to the top of the jacking mechanism 4-2-1. The lifting and clamping plate 4-2-2 is arranged between two adjacent rollers 12 to lift and fix the carbon block.

[0071] Specifically, the above-mentioned lifting mechanism 4-2-1 includes a plurality of lifting cylinders arranged side by side and spaced apart. The lifting cylinders are arranged spaced apart in the front-to-back direction. A lifting clamping plate 4-2-2 is arranged on the top of each lifting cylinder. The lifting clamping plate 4-2-2 is used to support the bottom of the charcoal block. When the charcoal block moves to the top of the lifting mechanism 4-2-1, the lifting cylinders at the corresponding positions are controlled to rise according to the front-to-back length of the charcoal block, so that the charcoal block can be lifted as a whole, thereby preventing the charcoal block from continuing to be transported backward following the conveyor line 1, thereby realizing the positioning of the charcoal block.

[0072] After the carbon block passes through the large surface cleaning station 4, it enters the small surface cleaning station 5.
