[0002] The vacuum degassing dosing furnace is a heat treatment equipment used to process materials such as metals, ceramics, and glass. It removes the gas in the furnace by applying a vacuum at high temperature to reduce oxidation, degas, and remove impurities, thereby achieving precise control and processing of the material.

[0003] After searching, it is found that a horizontal vacuum degassing furnace with the authorization announcement number of CN220793809U can add the inert protective gas in the gas storage box into the furnace body to achieve a protective effect, thereby improving the heating degassing effect. However, the sealing between the degassing furnace and the furnace cover is poor. When the inert gas is added into the furnace body, leakage is likely to occur, which can easily lead to heat dissipation inside the furnace body and affect the heat control inside the furnace body.

[0004] Therefore, a vacuum degassing quantitative furnace is proposed to solve the above problems. Utility Model Content

[0008] Preferably, a connecting pipe is installed at one end of a plurality of the piston cylinders, and a connecting pipe is installed between every two piston cylinders.

[0009] Preferably, a plurality of installation grooves are provided on the surface of the sealing ring, and the piston cylinder is installed through the inside of the installation grooves.

[0010] Preferably, the fixing part includes two fixing plates fixedly installed on both sides of the furnace cover, and limit blocks are fixedly installed on the front and rear sides of the furnace body.

[0013] The beneficial effects of the utility model are:

[0014] 1. The sealing mechanism can be used to increase the sealing performance between the furnace body and the furnace cover, and avoid the heat dissipation when the inert gas is added to the furnace body. The movement trend of the furnace cover installation can be used to insert the sealing ring into the sealing groove when the furnace cover and the furnace body are installed. As the furnace cover is continuously installed, the sliding rod inside the sealing ring drives the piston plate to move inward, injects the gas inside the piston cylinder into the piston cylinder inside the furnace cover, and drives the piston plate and the sliding rod inside the furnace cover to form a thrust on the ceramic sealing plate, pushing the ceramic sealing plate to the inside of the sealing ring, so as to form two seals between the furnace cover and the furnace body, and avoid the leakage of the inert gas when entering the furnace body, which affects the vacuum state inside the furnace body.

When the furnace cover and the furnace body are fully connected, use the pin shaft to limit the rack. When disassembling, the furnace cover can be disassembled by rotating the gear and separating the rack. This makes it easier to install the furnace cover and the furnace body, and at the same time locks the furnace cover to prevent the furnace cover from detaching during operation and affecting the degassing inside the furnace body.
