Water sealing structure for vacuum furnace

Abstract

The invention discloses a water sealing structure for a vacuum furnace and belongs to the field of vacuum furnaces. The structure comprises a furnace body support frame, wherein the vacuum furnace is arranged on the furnace body support frame, a sprue gate is arranged at the top of the vacuum furnace, and hinge shafts are arranged on two sides of the sprue gate and hinged to the top of one side of the furnace body support frame; a vacuum pouring channel is arranged in the direction of a pouring opening of the vacuum furnace, the vacuum pouring channel is arranged on one side of a furnace body supporting frame and located at the bottom of one side of the pouring opening, a water sealing groove is formed in the periphery of the vacuum pouring channel, and water is contained in the water sealing groove. A sealing cover is arranged above the sprue gate, the sealing cover is arranged in the water sealing groove in a buckled mode, the sealing cover is overturned along with the vacuum furnace, and the end of the sealing cover is located below the liquid level of water in the water sealing groove all the time.

Description

technical field [0001] The invention relates to the field of vacuum furnaces, in particular to a water sealing structure for a vacuum furnace. Background technique [0002] Vacuum melting furnaces are smelted and poured in a vacuum chamber, which is equipped with launders, isolation valves and other structures. However, the vacuum chamber of the above-mentioned traditional structure occupies a large area, has a complex structure, high cost, and is very inconvenient for later maintenance and repair; [0003] In order to reduce related costs, only the vacuum structure is used in the smelting part. However, at this time, the pouring will be in contact with the atmosphere, and the air cannot be isolated, and it is difficult to ensure the vacuum degree, resulting in tiny defects in the final product. [0004] In view of the above-mentioned problems in the prior art, the present invention designs and manufactures a vacuum furnace water-tight structure to overcome the above-mention...

AI Technical Summary

Problems solved by technology

[0002]The melting and pouring of the vacuum melting furnace is carried out in a vacuum chamber, which is equipped with launders, isolation valves and other structures. However, the vacuum chamber of the above-mentioned traditional structure occupies a large area , the structure is complex, the cost is high, and the later maintenance and repair are very inconvenient;

[0003] In order to reduce related costs, only the vacuum structure is used in the melting part. However, at this time, the pouring will be in contact with the atmosphere, and the air cannot be isolated, and it is difficult to ensure the vacuum degree requirements, resulting in minor flaws in the final product
