Problems solved by technology

[0003] Before using the vacuum furnace, it is necessary to pump out the air in the furnace body. During the pumping process, the residual processing dust and particles in the furnace can easily enter the inside of the pipeline, and it is prone to failure after long-term work; in addition, the traditional pre-heating The vacuum furnace is not convenient for centralized treatment of dust and particles, which makes the practicability of the vacuum furnace poor and needs to be improved

Abstract

The invention discloses a pre-vacuum furnace and an application method thereof. The pre-vacuum furnace comprises an outer furnace body and a gas circulation pipeline arranged at the bottom of the outer furnace body, wherein a filtering mechanism is arranged at the bottom of an inner cavity of the outer furnace body, and one end of the gas circulation pipeline extends to the inner cavity of the outer furnace body and is located below the filtering mechanism; an electric control valve is arranged at the joint of the gas circulation pipeline and the outer furnace body, and a vacuum pump is arranged on the surface of the gas circulation pipeline; and the filtering mechanism comprises an outer frame body and a metal filter screen, the metal filter screen is arranged on the inner side of the outer frame body, first limiting grooves are formed in the left side and the right side of the inner wall of the outer frame body, first limiting sliding rods are arranged at the left end and the right end of the metal filter screen, the first limiting sliding rods are located on the inner sides of the first limiting grooves, and the first limiting sliding rods are arranged in an L shape. According to the pre-vacuum furnace and the application method thereof, dust and particles entering the pipeline can be effectively reduced, the dust and the particles can be treated in a centralized mode, and the practicability of the vacuum furnace is improved.

Description

technical field [0001] The invention belongs to the technical field of vacuum furnaces, and in particular relates to a pre-evacuation furnace and an application method thereof. Background technique [0002] The vacuum furnace is a structure that uses a vacuum pump to discharge the air in the furnace to form a vacuum state. The vacuum furnace is widely used and can be used for smelting and brazing of metal workpieces. [0003] Before using the vacuum furnace, it is necessary to pump out the air in the furnace body. During the pumping process, the residual processing dust and particles in the furnace can easily enter the inside of the pipeline, and it is prone to failure after long-term work; in addition, the traditional pre-heating The vacuum furnace is not convenient for centralized treatment of dust and particles, which makes the practicability of the vacuum furnace poor and needs to be improved. Contents of the invention [0004] The purpose of the present invention is ...
