[0035] Working principle: First, a permalloy hydrogen protection box heat treatment furnace tank is moved to the working position. When in use, the first step is to place the permalloy material on the storage table 253 of the furnace tank to prepare for heat treatment. The hydrogen is stored in the gas storage box 231. Through the action of the air pump 233, the hydrogen is transported to the inside of the furnace tank through the first delivery pipe 232 and the second delivery pipe 234 to form a hydrogen protection atmosphere to prevent the permalloy from oxidizing during the heat treatment process. In the second step, the pressure measuring element 241 monitors the hydrogen pressure inside the furnace tank in real time to ensure that it is within the appropriate working pressure range. In case of abnormal pressure, the pressure can be released through the pressure relief pipe 242 to ensure the safety of the furnace tank. The sealing cover 221 and the fixing cap 222 ensure the sealing of the furnace tank during the heat treatment process, prevent hydrogen leakage, and ensure the safety of the heat treatment environment. In the third step, the heating tube 252 surrounds the surface of the internal working box 251, and the heating component 25 is started to heat the permalloy material. The material is evenly heated to reach the required heat treatment temperature. In the fourth step, the waste gas generated during the heat treatment process is collected into the waste gas temporary storage box 262 through the waste gas delivery pipe 261. The biological filter module 263 in the waste gas temporary storage box 262 performs preliminary biological purification treatment on the waste gas. The waste gas treated by the biological filter module 263 enters the waste gas treatment box 264, and is physically adsorbed by the inner connecting plate 265 and the waste gas adsorption plate 266 to further purify the waste gas. In the fifth step, the waste gas is filtered by the first filter plate 33 and the second filter plate 34 in the secondary filtration bin 32, and is finally discharged through the exhaust port 35 to ensure that the discharged gas meets the environmental protection standard. After the heat treatment is completed, the heating component 25 is turned off, and the furnace tank is cooled naturally or the cooling process is accelerated by the cooling system. After the furnace tank is cooled to a safe temperature, the sealing component 22 is opened and the heat-treated Permalloy material is taken out. In this way, the use process of a Permalloy hydrogen protection box type heat treatment furnace tank is completed.
