Abstract

The invention discloses a sealed type negative pressure vacuum drying oven which comprises an oven body, an oven door arranged on the side face of the oven body and layered oven supports arranged inside the oven body. The oven door is hinged to the side wall of the oven body through a hinge device, the hinge device comprises a chain bridge, the tail end of the chain bridge is inclined downwards, and the chain bridge is hinged to the side wall of the oven body through an oven body bearing base; and the head end of the chain bridge is hinged to the surface of the oven door through an oven door bearing base. According to the drying oven, the chain bridge type hinge device is used for hinging, a hinge point is located at the middle portion of the oven door rather than the edges, the bearing force of the oven door is strengthened, and damage to the oven door in the continues opening and closing process is reduced.

Description

technical field [0001] The invention relates to a drying oven, more specifically to a sealed negative pressure vacuum drying oven, which belongs to the technical field of pharmaceutical equipment. Background technique [0002] Vacuum drying is to heat and dry the dried material under vacuum conditions, and use a vacuum pump to pump air and dehumidify, so that the work can form a vacuum state, reduce the boiling point of water, and speed up the drying speed. Higher drying efficiency is obtained, the heat is fully utilized, and no impurities are mixed in the drying process. The door of a commonly used vacuum drying oven connects one side to the box body through a hinge to achieve the opening and closing function. However, this kind of box door has poor airtightness, low load-bearing capacity, and is easy to move, and cannot be adjusted after moving. Contents of the invention [0003] Object of the invention: The object of the invention is to address the deficiencies of the ...
