High-contact type energy-saving vacuum furnace with waste heat utilization function

Abstract

The invention discloses a high-contact type energy-saving vacuum furnace with a waste heat utilization function. The high-contact type energy-saving vacuum furnace comprises a furnace body fixed to the working ground, wherein a heating piece is mounted on the inner wall of the furnace body; and an upper water tank fixed to the top of the furnace body, wherein a condenser is mounted at the top of the upper water tank. The high-contact type energy-saving vacuum furnace comprises a mounting table fixed to the bottom of the inner wall of the furnace body, wherein a containing frame is arranged in the furnace body; a lower water tank fixed to the top of a mounting plate, wherein the top of the lower water tank is connected with the upper water tank through an air guide frame in a penetrating mode; a guide shaft mounted in the mounting plate and the lower water tank in a penetrating manner, wherein a second blade is mounted at the top of the guide shaft; and a main tooth roller connected to the interior of the top of the furnace body through an embedded shaft driven by a motor, wherein a sealing plate is arranged on one side of the main tooth roller, and the sealing plate is located in a movable groove. According to the high-contact type energy-saving vacuum furnace with the waste heat utilization function, water evaporation is achieved through waste heat, materials are stirred and evenly heated, and meanwhile the rapid heat dissipation function is achieved.

Description

technical field [0001] The invention relates to the technical field of vacuum furnaces, in particular to a high-contact energy-saving vacuum furnace with the function of utilizing waste heat. Background technique [0002] Vacuum furnace is a device for heating in a vacuum environment, which can completely eliminate oxidation and decarburization on the surface of the workpiece during the heating process, and can obtain a clean surface without metamorphic layer. It is widely used in ceramic firing, vacuum smelting, and electric vacuum parts. Degassing, annealing, brazing of metal parts, and ceramic and metal sealing, etc. However, the existing vacuum furnaces have the following problems in use: [0003] In the use of vacuum furnaces, most of the materials are put into the furnace and vacuumized for heating, but the existing vacuum furnaces are inconvenient to use the waste heat, resulting in the heat being only used for heating the materials, resulting in waste. At the same ti...
