Embodiment Construction
[0030] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0031] Such as figure 1 with figure 2As shown, the automatic gas delivery system for graphite purification provided by the present invention is controlled by a programmable logic controller (PLC), wherein the automatic gas delivery system includes a gas storage control system, a gas delivery control system and a furnace safety Control System.
[0032] The gas storage control system includes a gas storage room, which is divided into a chlorine gas room 1 and a freon gas room 2. There are several gas storage bottles 8 for storing chlorine gas or freon gas in the room, and each gas storage bottle 8 is equipped with a switch and a scale. Heavy module 9 and spraying water device; The gas cylinder 8 is a steel cylinder. The gas storage chambers are equipped with electric doors 3, and several concentration sensors 4 are respectively arranged in...

The invention discloses an automatic gas conveying system for graphite purification, and the system is controlled by a programmable logic controller (PLC), and comprises a gas storage control system, a gas conveying control system and a furnace body safe control system. The gas storage control system comprises a gas storage chamber; a gas storage cylinder is arranged in the gas storage chamber; a switch, a weighing module and a water spray device are arranged on the cylinder; and an electric door, a plurality of concentration sensors, an axial-flow fan, a shutter and a chloride recovery device are arranged in the chamber. The gas conveying control system comprises a gas conveying pipeline, a temperature sensor, a pressure sensor, a control valve and a switch valve. The furnace body safe control system comprises the concentration sensors. The sensors and the weighing module respectively input signals to the PLC; and the switch of the gas storage cylinder, the control valve, the switch valve, the water spray device, the chloride recovery device, the axial-flow fan, the shutter and the electric door respectively receive the signal control from the PLC. According to the automatic gas conveying system, the automatic conveying of gas can be realized, and the use is safe, high-efficiency and convenient.
Description
technical field [0001] The invention relates to a gas delivery system, in particular to an automatic gas delivery system for graphite purification. Background technique [0002] In the existing graphite purification industry, at high temperature (1600 to 3000 degrees), the gas (chlorine, nitrogen, argon, freon) is introduced, mainly through the simple use of pipelines directly into the interior of the graphitization furnace, relying on a gas Flow valve to determine the amount of gas supplied. This method has lower cost and lower technical content, but its disadvantages are also obvious. First of all, the operator needs to adjust the flow valve to ensure the amount of air supply, which is very inconvenient and requires a lot of labor costs. Secondly, the safety is low, there is basically no safety at all, and the leakage of harmful gases will cause great harm to the human body and the environment. And the air supply stability of this method is also unreliable. [0003] Th...
