Problems solved by technology
Due to the internal vacuum, the heating of this equipment has the advantages of no oxidation, no pollution, temperature control, precise energy consumption, etc. Usually, the vacuum furnace is a single-stage vacuum furnace, and the outside is in direct contact with the air. Due to gas leakage and atmospheric pressure difference, the inside of the furnace The vacuum degree is poor, so that some processes sensitive to air pressure cannot be carried out

The invention discloses a multistage vacuum furnace. The multistage vacuum furnace comprises an outer furnace body, an inner furnace body, a furnace cover, an inner air pump, an outer air pump, an inner vacuum pipe, an outer vacuum pipe, a support, a material conveying pipe and a heating furnace. The inner vacuum pipe is arranged below the inner furnace body and connected with the inner air pump. The outer vacuum pipe is arranged below the outer furnace body and connected with the outer air pump. A support is arranged on the periphery of the inner furnace body. The other end of the support is connected with the outer furnace body. The heating furnace is arranged inside the inner furnace body. The material conveying pipe is arranged above the inner furnace body. The furnace cover is arranged above the inner furnace body. By means of the method, the multistage vacuum furnace has the advantages of being high in reliability, high in vacuum capacity, compact in structure, high in technological adaptability, high in thermal insulation capacity, low in energy consumption and the like, and meanwhile the multistage vacuum furnace has wide market prospects in the vacuum processing field.
Description
technical field [0001] The invention relates to the field of vacuum equipment, in particular to a multistage vacuum furnace. Background technique [0002] The vacuum furnace uses the vacuum system in the specific space of the furnace cavity to discharge part of the material in the furnace cavity, so that the pressure in the furnace cavity is less than a standard atmospheric pressure, and the space in the furnace cavity achieves a vacuum state. This is a vacuum furnace. Due to the internal vacuum, the heating of this equipment has the advantages of no oxidation, no pollution, temperature control, precise energy consumption, etc. Usually, the vacuum furnace is a single-stage vacuum furnace, and the outside is in direct contact with the air. Due to gas leakage and atmospheric pressure difference, the inside of the furnace The vacuum degree is poor, so that some processes that are sensitive to air pressure cannot be carried out. Contents of the invention [0003] The technica...
