Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments (for ease of description and understanding, the following refers to...). Figure 5 (The above is described above). Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-6The present invention provides a technical solution: an anti-oxidation spraying device for anode carbon blocks, comprising a spraying box 1, a powder spraying mechanism 5, a rotating mechanism 4, a flipping clamping mechanism 6, and a lifting mechanism 3;

[0031] The spray box 1 has a cuboid structure. A placement plate 13 is set in the middle of the interior of the spray box 1 to support the anode carbon block to be sprayed. A rotating mechanism 4 is set at the lower end of the placement plate 13. The rotating mechanism 4 includes a rotating motor 41 and a support plate 42. The rotating motor 41 is installed at the lower end of the support plate 42. The output shaft of the rotating motor 41 is fixedly connected to the lower end face of the placement plate 13. Under the action of the rotating motor 41, the placement plate 13 is controlled to rotate, thereby driving the anode carbon block to rotate.

[0032] The powder spraying mechanism 5 is positioned corresponding to the placement plate 13. The powder spraying mechanism 5 includes a distribution box 51, a powder spraying head 52, and a connecting rigid pipe 53. The powder spraying head 52 is evenly distributed along the height direction of the distribution box 51. One end of the distribution box 51 is connected to the connecting rigid pipe 53. A strip-shaped through hole 8 is opened on the inner wall of the spraying box 1. The connecting rigid pipe 53 passes through the strip-shaped through hole 8 and is connected to the connecting hose 54. The connecting hose 54 is connected to the powder spraying pump. The powder spraying pump extracts the antioxidant powder from the powder storage box and sprays it onto the side of the anode carbon block through the powder spraying head 52. As the rotating mechanism 4 rotates, the side of the anode carbon block is sprayed around its entire length.

[0033] To facilitate the powder spraying mechanism 5 in spraying the bottom and top of the anode carbon block, a flipping clamping mechanism 6 is provided on the inner wall of the spraying box 1. The flipping clamping mechanism 6 includes clamping plates 61, clamping cylinders 62, mounting plates 63, and a flipping motor 64. The clamping plates 61 are symmetrically arranged on both sides above the placement plate 13. One side of the clamping plate 61 is connected to the telescopic end of the clamping cylinder 62. The clamping cylinder 62 is mounted on the mounting plate 63. One mounting plate 63 is rotatably connected to the inner wall of the spraying box 1 via a bearing, and the other mounting plate 63 is connected to the output shaft of the flipping motor 64. The flipping motor 64 is mounted on the outer side of the spraying box 1 and is connected to the inner wall of the spraying box 1 via a clamping cylinder 64. The cylinder 62 extends, causing the two clamping plates 61 to clamp the anode carbon block. A lifting mechanism 3 is set at the lower end of the rotating mechanism 4. The lifting mechanism is preferably a lifting cylinder. The lifting cylinder is installed on the fixed plate 2, which is fixed inside the spray box 1. There is a gap between the fixed plate 2 and the inner side wall of the spray box 1. The extension end of the lifting cylinder is connected to the lower surface of the support plate 42. After the clamping plates 61 clamp the anode carbon block on both sides, the lifting cylinder retracts, causing the rotating mechanism 4 and the placement plate 13 to move down. Then, under the action of the flipping motor 64, the anode carbon block is flipped, which facilitates the powder spraying mechanism 5 to spray powder on the bottom and top of the anode carbon block.

[0034] To facilitate uniform spraying of the bottom and top of the anode carbon block by the powder spraying mechanism 5, a telescopic mechanism 7 is provided on the outer side of the spraying box 1. The telescopic mechanism 7 includes a connecting block 71, an electric telescopic rod 72, and a fixing block 73. The connecting block 71 is fixed on the outer side of the connecting rigid pipe 53. The electric telescopic rod 72 is parallel to the strip-shaped through hole 8. The telescopic end of the electric telescopic rod 72 is connected to the connecting block 71, and the fixed end of the electric telescopic rod 72 is connected to the fixing block 73. The fixing block 73 is fixed on the outer side of the spraying box 1. Under the action of the electric telescopic rod 72, the powder spraying head 52 is driven to reciprocate horizontally to uniformly spray powder onto the bottom and top of the anode carbon block.

[0035] To prevent powder from escaping through the strip-shaped through-hole 8 during the movement of the powder spray head 52, baffles 9 are evenly distributed inside the strip-shaped through-hole 8. The baffles 9 are made of elastic plastic material.

[0036] In order to ensure that the spraying operation is carried out in a sealed environment and to create a good working environment, an end cover 10 is provided at the upper end of the spraying box 1. One end of the end cover 10 is connected to the flip cover motor 11, which controls the opening and closing of the end cover 10.

[0037] To facilitate the falling of the sprayed powder, the bottom of the spray box 1 is conical. At the same time, a powder extraction pipe 12 is provided at the bottom of the spray box 1. The powder extraction pipe 12 is connected to a powder extraction pump. After the spraying is completed, the powder extraction pump is started, and the powder suspended in the spray box 1 is extracted through the powder extraction pipe 12 for recycling, thus saving costs.

[0038] In use: The anode carbon block is moved to the top of the spray box 1 by the overhead crane, and the anode carbon block to be powdered is placed on the placement plate 13 inside the spray box 1. Then the flip-top motor 11 is started, and the control end cover 10 seals the opening. At this time, the powder pump is turned on, and the antioxidant powder in the powder storage box is extracted and sprayed onto the side of the anode carbon block through the powder spraying head 52. At the same time, the rotary motor 41 is turned on, and the rotary motor 41 drives the placement plate 13 to rotate, so that the antioxidant powder can be evenly sprayed onto the outer side of the anode carbon block.

[0039] After the outer circumference of the anode carbon block is sprayed, the clamping cylinder 62 is opened, and the clamping plate 61 is used to fix the two sides of the anode carbon block. Then the lifting cylinder retracts, driving the rotating mechanism 4 and the placement plate 13 to move downward. After moving to the lower position, the flipping motor 64 is started, driving the anode carbon block to flip so that the bottom of the anode carbon block is facing the powder spraying head 52. Antioxidant powder is sprayed on the bottom of the anode carbon block. At the same time, the electric telescopic rod 72 is opened, and the electric telescopic rod 72 controls the powder spraying head 52 to move back and forth, spraying evenly along the length of the bottom of the anode carbon block. After the bottom of the anode carbon block is sprayed, the flipping motor 64 controls the anode carbon block to flip 180°, and the top of the anode carbon block is sprayed in the same way.

[0040] After the anode carbon block is completely coated, the powder pump is started to extract the suspended dust in the coating box 1 for recycling.

Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
