Isolated type continuous tunnel vacuum furnace

Abstract

The invention discloses an isolated type continuous tunnel vacuum furnace. The isolated type continuous tunnel vacuum furnace comprises a plurality of tunnel cavities, vacuum valves, a material carrying vehicle and normal-pressure valve plate doors. The plurality of tunnel cavities are linearly connected side by side. The vacuum valves are arranged between the adjacent tunnel cavities. The material carrying vehicle is slidably connected in the tunnel cavities. The two ends of the tunnel cavities are provided with the normal-pressure valve plate doors. Each normal-pressure valve plate door comprises a valve frame, an air cylinder, an air cylinder supporting plate and a normal-pressure plate valve, wherein the air cylinder is vertically connected and fixed to the top of the valve frame; an output shaft of the air cylinder is connected with the air cylinder supporting plate; the air cylinder supporting plate is connected with the normal-pressure plate valve. Each tunnel cavity comprises acavity body, a servo motor, an air cylinder, a cooling mechanism, a shifting tooth mechanism and a heating movable contact mechanism. The isolated type continuous tunnel vacuum furnace provided by the invention can guarantee high consistence of the drying quality of dried objects, and is smooth and compact in drying process, stable in performance. Equipment is automatic and integral. Manpower andmaterial resources are saved. The isolated type continuous tunnel vacuum furnace is high in drying quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to an isolated continuous tunnel vacuum furnace. Background technique [0002] At present, most of the airtight drying rooms are in a limited space, with a single process, and it is impossible to allocate multiple processes in a limited space to achieve different levels of drying objects. Generally, the hot air blower heats the drying object for a long time and dries the moisture. Internally, its drying effect is only to remove part of the moisture of the object itself, and the environment it is in is still in a state of high temperature and high humidity. It is extremely unreasonable to dry objects at a higher level. From the outside, the drying object is affected by factors such as external air humidity and particles, which requires the required airtight cavity to be well sealed, which poses a great challenge to the installation and use of external heating equipment.

Problems solved by technology

Under normal pressure, the sealing valve of the traditional drying chamber is only opened and closed manually, which is labor-intensive

Some sealing valves with a drying chamber that can be vacuumed need to be additionally equipped with vacuum-breaking flanges and equipment, which has the disadvantages of long time-consuming, high maintenance costs, and high costs.
