[0002] When large-scale production of positive electrode material is carried out by high-temperature solid phase method, a certain proportion of glucose, polyethylene glycol, iron phosphate, lithium carbonate and the like are mixed, and after grinding, drying, magnetic removal and the like, are loaded into graphite crucible to enter roller kiln for long-time, hundreds-of-degrees high-temperature sintering. The reactants undergo complex physical / chemical reactions in multiple specific flow fields such as the temperature rising zone, the constant temperature zone and the temperature dropping zone, and finally generate the required positive electrode material such as lithium iron phosphate.

[0003] In order to continuously improve the performance of the positive electrode material, it is necessary to continuously adjust the proportion of the reactants, optimize the sintering curve and the like in the laboratory, and carry out small-batch sintering experiments in the tubular furnace. In this process, not only the final performance parameters of the product need to be concerned, but also the physical / chemical change process in the sintering process needs to be understood, so as to design stable and reliable process production parameters. Due to the characteristics of the existing tubular furnace, the phenomena in the sintering process cannot be observed, and only the change process of the reactants can be inferred by related theories and experience, and the sintering curve, the temperature rising rate of the tubular furnace, the air inlet amount and the like process parameters can be estimated, which has the disadvantages of low work efficiency, large error and the like, and affects the smooth implementation of the product mass production, causing certain production capacity and cost loss.

DETAILED DESCRIPTION

[0031] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, for the purpose of explanation, and are not to be understood as a limitation of the present application.

[0032] Please refer to Figure 1 The utility model discloses a tubular furnace. The tubular furnace is composed of a high temperature camera device 1, a main pipe 2, heat preservation bricks 3, a porcelain boat 4 and a visual light supplement device 5. The periphery of the main pipe 2 is wrapped by the heat preservation bricks 3, and the porcelain boat 4 is a carrier for materials and is located in the central region of the main pipe 2. The high temperature camera device 1 and the visual light supplement device 5 are inserted from both ends of the main pipe 2, and after being inserted, the inner side end of the high temperature camera device 1 and the inner side end of the visual light supplement device 5 are both away from the porcelain boat 4 by a certain distance, so that the high temperature device 1, the porcelain boat 4 and the visual light supplement device 5 form the same straight line on the vertical projection plane.

[0033] Figure 2The cross-sectional structure of the high-temperature camera device 1 in the embodiment of the present application is shown, and the whole can be approximately a long and narrow cylinder. The shell of the high-temperature camera device 1 is hollow, and contains a closed camera device connecting pipeline 1-13, one end of the pipeline is connected with a high-definition camera 1-11, the other end is connected with an external circuit board 1-1, and a data line connecting the two is arranged in the pipeline. The external circuit board 1-1 converts the image signals captured by the high-definition camera 1-11 into electrical signals for storage. Figure 2 The high-definition camera 1-11 includes a camera lens 1-10 and a camera right-angle prism lens 1-8, and a special light path design is adopted to obtain a special high-definition micro-lens, so that multi-angle shooting of materials in the porcelain boat 4 (not shown) can be realized.

[0034] The embodiment of the present application mainly considers the high-temperature resistance and dustproof properties of the device. In the high-temperature camera device 1, the shell is provided with circulating water channels, including a camera device outer circulating water channel 1-5 and a camera device intermediate circulating water channel 1-6. Both ends of the two channels are connected with a camera device cooling water inlet 1-3 and a camera device cooling water outlet 1-4. In the shell of the high-temperature camera device 1 and the camera device connecting pipeline 1-13, there is a pore, forming a camera device inside gas channel 1-7, one end of the channel is connected with a camera device gas inlet 1-2, and the other end is connected with a camera device gas outlet 1-9. The camera device gas outlet 1-9 is close to the camera right-angle prism lens 1-8.

[0035] Please refer to Figure 1 and Figure 2 In the shell of the high-temperature camera device 1, a camera device mounting flange 1-12 is further connected, and after the high-temperature camera device 1 is inserted into the main pipe 2, the flange can block the high-temperature overflow generated by the tubular furnace during operation, preventing operation hazards.

[0036] When the tubular furnace is in a working state, the high-temperature camera device 1 is started at the same time. The cooling water flows into the camera device outer circulating water channel 1-5 and the camera device intermediate circulating water channel 1-6 through the camera device cooling water inlet 1-3, and then flows out from the camera device cooling water outlet 1-4, so as to achieve the effect of cooling the high-temperature camera device 1. At the same time, fresh gas is sprayed into the camera device inside gas channel 1-7 from the camera device gas inlet 1-2, and then sprayed out from the camera device gas outlet 1-9. When the tubular furnace is in a working state, dust, tar and other substances can be generated, which are easy to adhere to the physical surface in the inner pipe 2. It is easy to understand that since the camera device gas outlet 1-9 is close to the camera right-angle prism lens 1-8, when the gas is sprayed out from the camera device gas outlet 1-9, the dust, tar and other substances will not adhere to the camera right-angle prism lens 1-8.

[0037] Figure 3The cross-sectional structure of the visual light supplement device 5 in the embodiment of the present application is shown, and the whole can be approximately a long cylinder. The shell of the visual light supplement device 5 is hollow, and contains a closed light supplement device connecting pipeline 5-11, one end of the pipeline is connected with a light source lamp bead 5-8, the other end is connected with a control circuit board 5-1, and a data line connected between the two is arranged in the pipeline. The control circuit board 5-1 can control the light source lamp bead 5-8 when the tubular furnace is working, so that the light source lamp bead 5-8 generates light.

[0038] The embodiment of the present application mainly considers the high-temperature resistance and dustproof characteristics of the device. In the visual light supplement device 5, the shell is provided with circulating water channels, including a light supplement device outer circulating water channel 5-5 and a light supplement device intermediate circulating water channel 5-6. The two ends of the two channels are connected with a light supplement device cooling water inlet 5-3 and a light supplement device cooling water outlet 5-4. In the shell of the visual light supplement device 5 and the light supplement device connecting pipeline 5-11, there is a pore, forming a light supplement device inner gas channel 5-7, one end of the channel is connected with a light supplement device gas inlet 5-2, and the other end is connected with a light supplement device gas outlet 5-9. The light supplement device gas outlet 5-9 is close to the light source lamp bead 5-8.

[0039] Please refer to Figure 1 and Figure 3 The shell of the visual light supplement device 5 is also connected with a light supplement device mounting flange 5-10, and after the visual light supplement device 5 is inserted into the main pipe 2, the flange can block the high-temperature overflow generated by the tubular furnace during work, preventing operation hazards.

[0040] When the tubular furnace is in a working state, the visual light supplement device 5 is started at the same time. The cooling water flows into the light supplement device outer circulating water channel 5-5 and the light supplement device intermediate circulating water channel 5-6 through the light supplement device cooling water inlet 5-3, and then flows out from the light supplement device cooling water outlet 5-4, so as to achieve the effect of cooling the visual light supplement device 5. At the same time, fresh gas is sprayed into the light supplement device inner gas channel 5-7 from the light supplement device gas inlet 5-2, and then sprayed out from the light supplement device gas outlet 5-9. When the tubular furnace is in a working state, dust, tar and other substances can be generated, which are easy to adhere to the physical surface in the inner pipe 2. It is easy to understand that since the light supplement device gas outlet 5-9 is close to the light source lamp bead 5-8, the dust, tar and other substances will not adhere to the light source lamp bead 5-8 when the gas is sprayed out from the light supplement device gas outlet 5-9.

It should be pointed out that any modification of the embodiment of the present application made by those skilled in the art does not deviate from the scope of the claims of the present application.
