[0028] The device needs to use inert gas to cool the carbon silicon plate after firing, so the environment for firing the carbon silicon plate must be provided with a ventilation system, so that when the inert gas is sprayed to cool the carbon silicon plate, the pressure value inside and outside the firing chamber is in a balanced state, and the air is in a flowable state, so as to prevent the risk of suffocation; when the carbon silicon plate needs to be fired, the staff work in pairs, first push the device outside the firing chamber, and push the carbon silicon plate to be fired from back to front, so that the carbon silicon plate is finally placed on the top between the four fixed plates 7. During this process, when the staff push the carbon silicon plate forward, the bottom of the carbon silicon plate first contacts the four guide plates 8. When the left and right length distance of the carbon silicon plate is consistent with the interval between the inner walls of the two guide plates 8 on the same side, the staff directly apply downward pressure to the carbon silicon plate, so that the carbon silicon plate can be smoothly placed on the top of the fixed plate 7, and the four corners of the carbon silicon plate are clamped by the guide plate 8.

At this time, the four corners of the carbon silicon plate are clamped by the guide plate 8, and the first carbon silicon plate is smoothly placed. When the first carbon silicon plate is fixed, it means that the position of the first carbon silicon plate is determined, and the left and right length of the same batch of carbon silicon plates to be fired is determined. Then the staff push the remaining carbon silicon plates from back to front in turn, so that each carbon silicon plate is placed on the top of the same horizontal four support plates 9, until each support plate 9 has a carbon silicon plate placed on it. At this time, the device reaches the limit of the number of carbon silicon plates that can be accommodated, and the left and right sides and the front side of each carbon silicon plate are stopped by the stopper 10, effectively preventing the carbon silicon plate from shaking left and right arbitrarily, thereby achieving the effect of fixing the carbon silicon plate.

[0030] When the same batch of carbon silicon plate is all burned out, and natural cooling for a period of time, the staff open the firing chamber ventilation system, so that gradually realize the firing chamber internal and external air pressure value tends to balance, in the process, the staff through the controller to start the infrared temperature sensor 12, the infrared temperature sensor 12 real-time detection and monitoring of the temperature of carbon silicon plate, when the temperature of carbon silicon plate reaches the preset value, that is, the temperature difference between carbon silicon plate and inert gas is small, carbon silicon plate can be directly cooled by injecting inert gas, and the carbon silicon plate will not produce thermal stress, at this time the staff through the controller to start the control valve 14, control valve 14 is in the open state, the inert gas in the high pressure gas cylinder 13 first through the gas pipe 15 into the shunt pipe 16, and then through the nozzle 17 is injected out, that is, the inert gas is directly sprayed on the carbon silicon plate, to cool the carbon silicon plate, so as to realize the cooling effect of carbon silicon plate, and further improve the firing efficiency of carbon silicon plate, when the carbon silicon plate is completely cooled, the staff through the controller to close the control valve 14, stop to carbon silicon plate injection inert gas, then the staff open the firing chamber, the device is moved to the specified unloading area, and from the bottom to the top, in turn, the carbon silicon plate can be taken off, when the top of the carbon silicon plate is taken off, the spring 6 reset, and drive the four support frame 2 to move inward, four pulley one 11 respectively slide inward, while four telescopic rod 5 respectively slide into its same side sleeve 4, four protection warehouse two 301 respectively slide into its same side protection warehouse one 3, at this time the unloading of carbon silicon plate is completed; if you need to continue to fire carbon silicon plate, repeat the above steps can be.

[0031] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application.
