[0002] The shell making process of investment casting mainly includes the steps of surface layer production, transition layer production, reinforcement layer production, sealing layer production and dewaxing. After the sealing layer is applied and air-dried, the mold shell on the upper edge of the main riser and the gate needs to be knocked off to expose the wax mold inside, and then inverted in the dewaxing kettle for dewaxing. After dewaxing is completed, the mold shell to be poured is formed.

[0003] After searching, the publication number is: a dewaxing kettle for investment casting, including a kettle body, a feed window is arranged in the middle position of one end of the front side of the kettle body, a warehouse door is arranged at the edge position of the kettle body close to the feed window, an installation bin is arranged on one side of the top of the kettle body, a temporary storage bin is arranged in the middle position of the top of the kettle body, and an air inlet pipe is arranged on the side of the top of the kettle body away from the installation bin; the utility model cooperates with the air pipe A, the temporary storage bin, the installation bin, the ball, the pressing rod, the pressing switch, the spring, the one-way valve and the air pipe B, so that when the air pressure inside the kettle body is relatively high, it can be transported to the temporary storage bin for storage through the installation bin, and can be transported to the air inlet pipe through the air pipe A again to enter the kettle body. When the air pressure does not increase, the warning light is turned on to warn, thereby realizing the safe control of the air pressure in the reactor, avoiding the occurrence of dangerous production accidents, and ensuring the normal operation of production.

[0004] However, the device has the following disadvantages: although the above-mentioned device can turn on the warning light to give an alarm when the air pressure does not increase, thereby achieving safe control of the air pressure in the reactor, avoiding the occurrence of dangerous production accidents and ensuring the normal operation of production, but in actual use, the device is not equipped with a waste gas treatment device. The waste gas may contain volatile organic compounds (VOCs), particulate matter and other harmful substances. Direct discharge into the atmosphere will pollute the surrounding environment, affect the air quality, and even endanger the health of nearby residents.

[0005] Therefore, in view of the above problems, a dewaxing kettle for investment casting is proposed. Utility Model Content
