[0002] The anode is the central component of the aluminum electrolytic cell. The anode consists of four parts: the anode aluminum guide rod, the aluminum-iron explosion welding block, the anode steel claw and the anode carbon block. Among them, the anode carbon block plays a dual role of conducting electricity and participating in the electrochemical reaction in the aluminum electrolytic cell.

[0003] Before the anode carbon block is immersed in the electrolyte, the upper and lower sides are covered with covering materials, but the other four sides are exposed to the high temperature environment and cause oxidation.

Therefore, in order to solve the above problems, it is necessary to spray anti-oxidation coating on the four sides of the anode carbon block.

[0004] In the existing technology, when performing spraying operations, some methods spray the four sides of the anode carbon block manually; others use mechanical methods to drive two nozzles to spray the two opposite sides of the anode carbon block respectively, and then adjust the direction of the anode carbon block through a reversing mechanism, and then use the two nozzles to spray the remaining two sides respectively; although the above-mentioned mechanical spraying method improves the operating efficiency to a certain extent compared with the manual spraying method, it still has the problem of low spraying efficiency in the actual production process.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-Figure 5 As shown, this embodiment discloses a spraying device for anti-oxidation coating of anode carbon blocks, including a hanging chain conveyor 1 for suspending and conveying the anode and a spraying mechanism 2, the spraying mechanism 2 is provided with a spraying station, and the spraying station is located on the conveying track of the hanging chain conveyor 1; the spraying mechanism 2 includes a base 21, the base 21 is provided with a guide rail 22 arranged in a ring, the inner side of the guide rail 22 is provided with a chain 24 arranged in a ring through a driving assembly 23, two mounting seats 25 are connected to the chain 24, and the mounting seat 25 is movably engaged with the guide rail 22; the mounting seat 25 is connected to a nozzle 27 through a nozzle bracket 26, and the nozzle 27 is connected to the feeding assembly through a hose.

[0027] In this embodiment, in the initial state, the two mounting seats 25 are diagonally arranged on both sides of the guide rail 22 (the upper left corner and the lower right corner). When the hanging chain conveyor 1 drives the anode into the spraying station, the two nozzles 27 are respectively located on a diagonal line of the anode carbon block; thereafter, the driving assembly 23 is started to drive the chain 24 to move counterclockwise, and the chain 24 drives the mounting seat 25, the nozzle bracket 26 and the nozzle 27 to move as a whole on the guide rail 22; at the same time, the feeding assembly delivers the paint to the nozzle 27 through the hose, and the paint is atomized and sprayed through the nozzle 27; when the chain 24 drives the two nozzles 27 to move 180° respectively, each nozzle 27 completes the spraying operation of the two adjacent sides of the anode carbon block, and the spraying of the four sides of the anode carbon block can be completed by the two nozzles 27.

[0028] By adopting this solution, the drive assembly 23, chain 24, guide rail 22, mounting seat 25 and nozzle bracket 26 are arranged to achieve the effect of driving the two nozzles 27 to perform circular motion. With the cooperation of the feeding assembly, the two nozzles 27 can complete the spraying operation on the four sides of the anode carbon block at one time, thereby improving the spraying efficiency.

[0029] Further optimization scheme, such as Figure 1 、 Figure 2 As shown, a stabilizing mechanism 3 is provided on both sides of the base 21, and the stabilizing mechanism 3 includes a horizontal driving part 31. The action end of the horizontal driving part 31 is fixedly connected to a sleeve 33 through a mounting block 32. A horizontally arranged connecting shaft 34 is rotatably connected in the sleeve 33. A torsion spring is sleeved on the connecting shaft 34, and both ends of the torsion spring are respectively against the inner wall of the sleeve 33; one end of the connecting shaft 34 extends to the outside of the sleeve 33 and is fixedly connected to a rocker arm 35, and the rocker arm 35 is located on the conveying track of the suspension chain conveyor 1; a limit plate 36 is provided on one side of the rocker arm 35, and the limit plate 36 is fixedly connected to the mounting block 32.

[0030] In this embodiment, in the initial state, the pendulum rod 35 is in a vertical state. When the hanging chain conveyor 1 drives the anode into the spraying station, the anode carbon block will first contact the pendulum rod 35 and drive the pendulum rod 35 to rotate counterclockwise around the axis of the connecting shaft 34; at this time, the torsion spring twists and generates a rebound force; after the anode carbon block continues to move and enters the spraying station, the pendulum rod 35 returns to a vertical state under the action of the rebound force generated by the torsion spring; thereafter, the pendulum rod 35 is driven by the horizontal drive unit 31 to move in a straight line toward the direction close to the anode carbon block until the top of the pendulum rod 35 contacts the bottom edge of the anode carbon block.

[0031] It should be noted that the movement direction of the action end of the horizontal driving part 31 is the same as the conveying direction of the anode carbon block; when the swing rod 35 contacts the anode carbon block, the top end of the swing rod 35 is about 2 mm away from the bottom surface of the anode carbon block.

[0032] By adopting this solution, the limit plate 36 is set, and when the pendulum rod 35 contacts the anode carbon block, the pendulum rod 35 can be prevented from rotating in the clockwise direction, thereby improving the stability of the contact between the pendulum rod 35 and the anode carbon block; by bringing the pendulum rod 35 into contact with the anode carbon block, the shaking of the anode carbon block during the spraying process can be significantly reduced.

[0033] Further optimization scheme, such as Figure 1 As shown, the driving assembly 23 includes a plurality of sprockets 231, which are arranged in a ring shape on the inner side of the chain 24, and the sprockets 231 are meshed and connected with the chain 24; a rotating driving component 232 is provided on the base 21, one of the sprockets 231 is fixedly mounted on the output shaft of the rotating driving component 232, and the remaining sprockets 231 are rotatably connected to the base 21 through a rotating shaft.

[0034] In this embodiment, the rotary drive component 232 is configured as a drive motor. The fixed end of the rotary drive component 232 is fixed to the base 21, and the output shaft of the rotary drive component 232 extends upward. The rotary drive component 232 drives one of the sprockets 231 to rotate. When the chain 24 meshes with the sprocket 231, the remaining sprockets 231 rotate synchronously in the same direction, thereby driving the chain 24.

[0035] Further optimization scheme, such as Figure 2 As shown, the horizontal driving part 31 includes a linear driving component 311 provided on the base 21 , the action end of the linear driving component 311 is connected to a slide plate 312 , the slide plate 312 is slidably connected to the base 21 , and the mounting block 32 is fixed on the slide plate 312 .

[0036] In this embodiment, the linear drive component 311 is configured as a cylinder. The fixed end of the linear drive component 311 is fixed to the base 21, and the operating end of the linear drive component 311 is hingedly connected to the slide 312. The linear drive component 311 drives the slide 312 to move linearly, thereby achieving the effect of driving the entire mounting block 32, sleeve 33, connecting shaft 34, and rocker arm 35 to move linearly.

[0037] Further optimization scheme, such as Figure 3 As shown, a plurality of rollers 251 are provided on both sides of the bottom of the mounting seat 25 , and a ring-shaped clamping groove 221 is provided on both sides of the guide rail 22 . The mounting seat 25 is movably connected to the guide rail 22 through the rollers 251 and the clamping groove 221 .

[0038] In this embodiment, multiple axles are fixed to the bottom of the mounting base 25. The number of axles is the same as the number of rollers 251, and they correspond one to one. The rollers 251 are rotatably connected to the corresponding axles. The axles, rollers 251, and slots 221 provide a movable engagement between the mounting base 25 and the guide rail 22, ensuring the stability of the mounting base 25 during movement.

[0039] Further optimization scheme, such as Figure 1 、 Figure 4 As shown, a forward limiter 28 and a reverse limiter 29 are fixedly connected to the side wall of the guide rail 22 through a mounting plate, and the two mounting seats 25 are respectively limited and matched with the guide rail 22 through the forward limiter 28 and the reverse limiter 29.

[0040] In this embodiment, the mounting plate is fixed to the upper left corner of the guide rail 22, and the forward limiter 28 and the reverse limiter 29 are arranged side by side. In the initial state, the two mounting seats 25 are diagonally arranged on both sides of the guide rail 22 (upper left corner and lower right corner). At this time, the mounting seat 25 located at the upper left corner is in contact with the forward limiter 28; the drive assembly 23 drives the chain 24 to rotate counterclockwise (reverse), and when the mounting seat 25 located at the lower right corner is in contact with the reverse limiter 29, the drive assembly 23 stops moving. At this time, both nozzles 27 have completed 180° movement; after the next anode enters the spraying station, the drive assembly 23 drives the chain 24 to rotate clockwise (forward) to start the spraying operation.

[0041] According to a further optimized solution, the feeding assembly includes a barrel and a sprayer arranged outside the base 21, the feeding end of the sprayer is connected to the barrel, and the discharging end of the sprayer is connected to the nozzle 27 through a hose.

[0042] In this embodiment, there are two feeding assemblies, which respectively provide paint to the two nozzles 27; the barrel is used to hold the paint to be sprayed, and the sprayer pressurizes the paint in the barrel and transports it to the nozzle 27 through a hose for atomized spraying; the hose has sufficient margin to meet the movement needs of the nozzle 27.

[0043] It should be noted that if Figure 5 As shown, the conveying end of the suspension chain conveyor 1 is connected to the through hole at the top of the anode aluminum guide rod. When the anode carbon block enters the spraying station, the suspension chain conveyor 1 stops running; when the top of the rocker arm 35 contacts the bottom edge of the anode carbon block, the spraying operation begins.

[0044] The cylinder, the drive motor, the sprayer and the hanging chain conveyor 1 are all prior arts, and their working principles and methods of use are all known, which will not be described in detail here.

[0045] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
