[0002] During the processing of the cathode material, it is necessary to use a kiln furniture - a sagger to load the cathode material powder for drying. Due to the strong alkalinity of lithium hydroxide in the material, in order to ensure the service life of the sagger, anti-corrosion coatings need to be sprayed on the surface and inner wall of the sagger during its production. In order to improve production efficiency, drying equipment is required to dry the anti-corrosion coating on the surface of the sagger.

[0003] In the prior art, after the anti-corrosion coating on the sagger is dried by a drying box, since the sagger rod is baked at a high temperature, the temperature on its surface is relatively high. In order to avoid scalding when taking the sagger, the sagger inside the drying box needs to be cooled for a period of time before it can be taken out. This phenomenon easily affects the efficiency of drying the anti-corrosion coating on the surface of the sagger.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0028] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the utility model.

[0029] Please refer to Figures 1-6As shown in the figure, the utility model relates to a drying device for a corrosion-resistant coating of a sagger, which includes a drying box 1. A through groove 2 is opened at the bottom of the drying box 1. An installation block 3 is movably connected inside the through groove 2. A universal wheel 4 is fixedly installed at the bottom of the installation block 3. The top of the installation block 3 is fixedly connected with an L-shaped moving plate 5. The inner wall of the L-shaped moving plate 5 is fixedly connected with a placement rack 6. A plurality of the placement racks 6 are arranged in an array. A fixing component 7 is arranged at the top of the drying box 1 and the front of the L-shaped moving plate 5. A sliding groove 8 is opened inside the inner wall of the drying box 1. A sliding bar 9 is movably connected inside the sliding groove 8. A drying component 10 is fixedly connected to one side of the sliding bar 9. A connecting component 11 is arranged at the rear of the drying component 10. A limiting component 12 is arranged at the back of the drying box 1. The limiting end of the limiting component 12 is movably connected with the connecting component 11.

[0030] After the drying of the corrosion-resistant coating of the sagger is completed, directly drive the fixing component 7, so that the fixing component 7 no longer fixes the L-shaped moving plate 5. At this time, the L-shaped moving plate 5 can be pulled, so that the L-shaped moving plate 5 drives the installation block 3 to move inside the through groove 2. The universal wheel 4 at the bottom of the installation block 3 rolls on the ground, so that the L-shaped moving plate 5 drives the sagger on the placement rack 6 to directly move out of the drying box 1, so that the sagger on the placement rack 6 can be cooled outside the drying box 1. At the same time, there are multiple L-shaped moving plates 5. At this time, the L-shaped moving plate 5 equipped with the sagger that has not been dried can be directly moved into the drying box 1.

[0031] With the assistance of the universal wheel 4, the L-shaped moving plate 5 can move out of the drying box 1, so that the L-shaped moving plate 5 can drive the dried sagger to move out of the drying box 1 and be cooled outside the drying box 1. At the same time, there are multiple L-shaped moving plates 5. When placing a sagger on one L-shaped moving plate 5 for drying, the sagger can be placed on the placement rack 6 of another L-shaped moving plate 5. So that after the L-shaped moving plate 5 moves out of the drying box 1, another L-shaped moving plate 5 can drive the sagger that has not been dried into the drying box 1. The above settings enable the drying device to continuously perform drying operations on the sagger with the cooperation of multiple L-shaped moving plates 5, thus improving the efficiency of drying the corrosion-resistant coating of the sagger.

[0033] By driving the motor 705, the motor 705 drives the first screw rod 702 to rotate, and the first screw rod 702 drives the L-shaped fixing plate 703, so that the L-shaped fixing plate 703 moves out of the inside of the fixing frame 704, so that the L-shaped fixing plate 703 no longer fixes the L-shaped moving plate 5. The above setting makes it only necessary to drive the motor 705 to release the fixation of the L-shaped moving plate 5, and the whole operation is relatively convenient; when the L-shaped fixing plate 703 moves, the first guiding column 706 can guide the L-shaped fixing plate 703, so that the stability of the L-shaped fixing plate 703 during movement can be ensured.

[0034] In one embodiment, for the above-mentioned drying component 10, the drying component 10 includes an installation frame 101, the installation frame 101 is fixedly connected to the sliding strip 9, an installation groove 102 is opened at the top of the installation frame 101, a lamp holder 103 is fixedly connected to the inner wall of the installation groove 102, and a U-shaped infrared lamp tube 104 is inserted into the top of the lamp holder 103.

[0035] After the L-shaped moving plate 5 drives the placement rack 6 to move into the drying box 1, the crucible on the placement rack 6 is exactly inside the installation frame 101. At this time, the infrared radiation emitted by the U-shaped infrared lamp tube 104 installed inside the installation groove 102 can irradiate the surface of the crucible on the placement rack 6, so that the surface of the crucible is quickly heated up and the anti-corrosion coating is dried. And there are multiple drying components 10 corresponding to the placement rack 6 inside the drying box 1. This setting ensures that the crucibles on each layer of the placement rack 6 have corresponding drying components 10 to dry them, so that the drying efficiency of the crucibles on the multi-layer placement rack 6 can be ensured.

[0036] In one embodiment, for the above-mentioned connection component 11, the connection component 11 includes a connection block 111. The connection block 111 is fixedly connected to the installation frame 101. The drying box 1 is provided with a connection groove 112 corresponding to the connection block 111. The connection block 111 is movably connected to the connection groove 112. One end of the connection block 111 is provided with a conductive socket 113. The conductive socket 113 is electrically connected to the lamp socket 103. The inner wall of the connection groove 112 is provided with a shielding groove 114. A shielding plate 115 is movably connected inside the shielding groove 114. The shielding plate 115 is fixedly connected to the connection block 111.

[0037] The conductive socket 113 can be connected to an external circuit, so that the external circuit can supply power to the U-shaped infrared lamp tube 104 through the conductive socket 113 and the lamp socket 103. When the U-shaped infrared lamp tube 104 is damaged, directly unplug the corresponding external circuit from the conductive socket 113, and then start pulling the installation frame 101, so that the installation frame 101 drives the sliding strip 9 to move in the sliding groove 8. At the same time, the connection block 111 also moves from the back of the drying box 1 to the inside of the drying box 1 under the drive of the installation frame 101, and directly moves out of the inside of the drying box 1 under the drive of the installation frame 101, so that the operator can replace the U-shaped infrared lamp tube 104 outside the drying box 1, and it is relatively convenient to move the installation frame 101 out of the inside of the drying box 1, so that it is relatively convenient to replace the damaged U-shaped infrared lamp tube 104; when the connection block 111 is inside the connection groove 112, the shielding groove 114 can seal the connection between the connection block 111 and the connection groove 112 through the shielding plate 115, so that the heat inside the drying box 1 is not easy to flow to the back of the drying box 1, so that the connection between the external circuit and the conductive socket 113 will not be damaged by high temperature.

[0038] In one embodiment, for the above-mentioned limiting component 12, the limiting component 12 includes a support plate 121. The bottom of the support plate 121 is rotatably connected to a second screw rod 122. A moving plate 123 is threadedly connected to the outer surface of the second screw rod 122. A fixing column 124 is fixedly connected to the top of the moving plate 123. A fixing hole 125 is provided at the top of the connection block 111. The fixing column 124 is movably connected to the fixing hole 125. The bottom of the support plate 121 is fixedly connected to a second guiding column 126. The moving plate 123 is movably connected to the second guiding column 126. The top end of the second screw rod 122 penetrates through the support plate 121 and is fixedly connected to a control ring 127.

[0039] When moving the installation frame 101 out of the interior of the drying oven 1, the second screw 122 is rotated by the control ring 127, and the second screw 122 drives the moving plate 123, so that the moving plate 123 moves downward under the guidance of the second guiding column 126. At the same time, the moving plate 123 moves the fixing column 124 out of the fixing hole 125, so that the fixing column 124 no longer limits the connecting block 111 through the fixing hole 125, and the installation frame 101 can also move out of the interior of the drying oven 1 normally. To sum up, the fixing column 124 can limit the connecting block 111 through the fixing hole 125, and the limited connecting block 111 can then limit the installation frame 101, so that the installation frame 101 is not easily moved out of the interior of the drying oven 1. When releasing the limit on the installation frame 101, it is only necessary to rotate the second screw 122 through the control ring 127, and the operation is relatively convenient.

[0040] In one embodiment, for the above-mentioned drying oven 1, a first sealing groove 13 is formed in the front surface of the drying oven 1, a sealing frame 14 is movably connected inside the first sealing groove 13, the sealing frame 14 is fixedly connected to the inner wall of the L-shaped moving plate 5, a second sealing groove 15 is formed in the inner wall of the drying oven 1, a second sealing strip 16 is movably connected inside the second sealing groove 15, the second sealing strip 16 is fixedly connected to the side surface of the L-shaped moving plate 5, and a handle 17 is fixedly connected to the front surface of the L-shaped moving plate 5.

[0041] When moving the L-shaped moving plate 5 into the interior of the drying oven 1, the sealing frame 14 can move into the first sealing groove 13, and the sealing strip 16 moves into the second sealing groove 15. The cooperation of the first sealing groove 13, the sealing frame 14, the second sealing groove 15 and the sealing strip 16 ensures the sealing performance at the connection between the L-shaped moving plate 5 and the drying oven 1, so that the heat inside the drying oven 1 is not easily dissipated from the interior of the drying oven 1 during the drying operation of the sagger. The setting of the handle 17 makes it convenient to pull the L-shaped moving plate 5.

[0042] In summary, by means of the above technical solution of the present utility model, the motor 705 is driven, so that the motor 705 drives the first screw rod 702 to rotate. The first screw rod 702 then drives the L-shaped fixing plate 703, so that the L-shaped fixing plate 703 moves out from the inside of the fixed frame 704, so that the L-shaped fixing plate 703 no longer fixes the L-shaped moving plate 5. At this time, the L-shaped moving plate 5 can move out from the inside of the drying box 1 with the assistance of the universal wheels 4, so that the L-shaped moving plate 5 moves the dried crucible out from the inside of the drying box 1 through the placing rack 6 and cools it outside the drying box 1. Then, another L-shaped moving plate 5 with an unfired crucible is moved into the drying box 1; when the U-shaped infrared lamp tube 104 is damaged, the second screw rod 122 is rotated through the control ring 127, and the second screw rod 122 then drives the moving plate 123, so that the moving plate 123 moves downward under the guidance of the second guide post 126. At the same time, the moving plate 123 moves the fixing column 124 out from the inside of the fixing hole 125, so that the fixing column 124 no longer limits the connecting block 111 through the fixing hole 125. Then, the corresponding external circuit is unplugged from the conductive slot 113, and the installation frame 101 is pulled, so that the installation frame 101 drives the slide bar 9 to move in the chute 8. At the same time, the connecting block 111 moves from the back of the drying box 1 to the inside of the drying box 1 through the connecting slot 112 driven by the installation frame 101, and directly moves out from the inside of the drying box 1 driven by the installation frame 101. Then, the operator replaces the U-shaped infrared lamp tube 104 on the installation frame 101 outside the drying box 1.

[0043] Through the above technical solutions: 1. The L-shaped moving plate 5 can be moved out from the inside of the drying box 1 through the universal wheels 4, so that the L-shaped moving plate 5 can drive the fired crucible out of the inside of the drying box 1 and be cooled outside the drying box 1. Then, the other L-shaped moving plate 5 is moved, and it can drive the unfired crucible into the inside of the drying box 1. The above settings enable the drying equipment to continuously dry the crucibles with the cooperation of multiple L-shaped moving plates 5, thus improving the efficiency of drying the anti-corrosion coating of the crucibles; 2. The external circuit can supply power to the U-shaped infrared lamp tube 104 through the conductive slot 113 and the lamp holder 103. The fixing column 124 can limit the connecting block 111 and the mounting frame 101 through the fixing hole 125. When the U-shaped infrared lamp tube 104 needs to be replaced, directly unplug the corresponding external circuit from the conductive slot 113, and by rotating the second screw 122, the fixing column 124 no longer limits the connecting block 111, and then start to pull the mounting frame 101, so that the mounting frame 101 and the connecting block 111 can be directly moved out from the inside of the drying box 1, so that the operator can replace the U-shaped infrared lamp tube 104 outside the drying box 1, and it is relatively convenient to move the mounting frame 101 out from the inside of the drying box 1, so that it is relatively convenient to replace the damaged U-shaped infrared lamp tube 104.
