Description

TECHNICAL FIELD

[0001] The application relates to the technical field of alkali metal deposition, in particular to a heat supplement device for an alkali metal heating furnace. BACKGROUND

[0002] The process of depositing alkali metal on a workpiece after heating is generally referred to as alkali metal deposition technology, which involves heating alkali metal (such as lithium, sodium, potassium, etc.) to volatilize the alkali metal, and finally depositing the alkali metal on the surface of a workpiece located at a cold end.

[0003] In the prior art, the alkali metal is heated at one end of a metal heating furnace to volatilize the alkali metal, and the volatilized alkali metal gas enters a hot oven along a glass pipeline and is deposited on the surface of a workpiece. However, the existing metal heating furnace structure is generally an open structure, and the pipeline part connected between the metal heating furnace and the hot oven is exposed to the air, which causes the volatilized alkali metal gas to be deposited on the bare pipeline, thereby reducing the deposition effect of the alkali metal on the workpiece, and thus further improvement is needed. CONTENT OF THE UTILITY MODEL

[0016] Preferably, a positioning column is fixedly connected to the top wall of the heating furnace body, and a positioning hole for inserting the positioning column is opened on the lower end face of the heat insulation cover.

[0017] By adopting the above technical solution, the positioning column fixedly connected to the top wall of the heating furnace body cooperates with the positioning hole opened on the lower end face of the insulation cover to ensure the accuracy and stability of the insulation cover during installation, and avoid the insulation cover from shifting or falling off during use, thereby ensuring the continuous and effective heating of the pipeline by the supplementary heat heater and improving the reliability and safety of the entire system.

[0029] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0030] Example 1:

[0031] This application discloses a heat replenishment device for an alkali metal heating furnace, referring to... Figure 1The furnace includes a heating furnace body 1, and a heating cylinder 11 is fixedly inserted through the top wall of the heating furnace body 1. The heating cylinder 11 is arranged vertically, with the upper end of the heating cylinder 11 being an open end and the lower end of the heating cylinder 11 being a closed end. A heating wire 12 is spirally wound on the outer peripheral wall of the heating cylinder 11.

[0032] The heating furnace body 1 is provided with a pipe 2, which has a vertical pipe section and a horizontal pipe section. The vertical pipe section of the pipe 2 is inserted into the inner cavity of the heating cylinder 11. The lower end of the vertical pipe section of the pipe 2 is detachably connected to a container bottle 13 built into the heating cylinder 11. In this embodiment, the container bottle 13 is screwed to the vertical pipe section of the pipe 2. The container bottle 13 is filled with alkali metal. The horizontal pipe section of the pipe 2 passes through the hot drying oven 10. The vertical pipe section of the pipe 2 is fixedly connected to a sealing plate 21 that abuts against the upper end face of the heating cylinder 11.

[0033] The top of the heating furnace body 1 is provided with a heat insulation cover 3 covering the external pipe 2. One side of the heat insulation cover 3 has a clearance groove for the horizontal pipe section of the pipe 2 to slide through. A supplementary heat heater 31 for heating the pipe 2 is fixedly connected to the inner wall of the top of the heat insulation cover 3. The supplementary heat heater 31 is located above the horizontal pipe section of the pipe 2. The lower end face of the heat insulation cover 3 abuts against the upper end face of the heating furnace body 1. In this embodiment, a handle 32 is fixedly connected to the outer wall of the top of the heat insulation cover 3, and the handle 32 is fitted with a heat insulation sleeve 33.

[0034] A positioning post 14 is fixedly connected to the upper edge of the heating furnace body 1, and a positioning hole 34 is provided on the lower end face of the insulation cover 3 for the positioning post 14 to be inserted. The positioning post 14 fixedly connected to the top wall of the heating furnace body 1 cooperates with the positioning hole 34 on the lower end face of the insulation cover 3 to ensure the accuracy and stability of the insulation cover 3 during installation, and to prevent the insulation cover 3 from shifting or falling off during use. This ensures the continuous and effective heating of the pipeline 2 by the supplementary heat heater 31, and improves the reliability and safety of the entire system.

[0035] The implementation principle of this application embodiment is as follows: An insulation cover 3 is added to reduce heat loss from the heating furnace body 1. The insulation cover 3 provides an installation carrier for the supplementary heating heater 31. The supplementary heating heater 31 heats the pipe 2 exposed to the heating furnace body 1, maintaining the temperature of the exposed pipe 2 and reducing premature condensation and deposition of alkali metals on the inner wall of the pipe 2, thereby reducing waste of alkali metal materials. A handle 32 is added to facilitate manual lifting or moving of the insulation cover 3 by operators, improving the ease of operation during equipment maintenance and repair.

[0036] Example 2:

[0037] The difference from Example 1 is that, referring to Figure 2 , Figure 3The alkali metal heating furnace reheating device also includes a frame 4, a lifting guide frame 41 fixedly connected to the frame 4, a slide block 42 slidably connected to the lifting guide frame 41, a connecting plate 421 fixedly connected to the slide block 42, and the connecting plate 421 fixedly connected to the top outer wall of the insulation cover 3. The lifting guide frame 41 is provided with a lifting drive component 43 for driving the slide block 42 to slide. Specifically, the lifting drive component 43 includes a lead screw 431 rotatably connected to the lifting guide frame 41 and a motor 432 fixedly connected to the lifting guide frame 41. The output shaft of the motor 432 is coaxially fixedly connected to the lead screw 431, and the lead screw 431 is threaded through the slide block 42.

[0038] The frame 4 is fixedly connected to a lifting platform 44. Specifically, the lifting platform 44 is a scissor-type lifting platform 44. The heating furnace body 1 is fixedly connected to the upper end face of the lifting platform 44. The frame 4 is fixedly connected to a support 45. The horizontal pipe section of the pipe 2 is fixedly installed through the support 45.

[0039] The implementation principle of this application embodiment is as follows: when the alkali metal in the container bottle 13 is consumed, the lifting platform 44 descends, causing the heating furnace body 1 and the heating cylinder 11 to descend as a whole, so that the container bottle 13 is located above the heating cylinder 11. Furthermore, the motor 432 drives the lead screw 431 to rotate, thereby causing the slide 42, the connecting plate 421, the heat insulation cover 3 and the heat insulation cover 3 to rise together, increasing the distance between the heat insulation cover 3 and the heating furnace body 1, making it easier to replace the container bottle 13.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
