Host computer of hot plate type continuous vacuum drying system

Abstract

The invention relates to a main-machine of a hot-plate constant vacuum drying system. The main-machine comprises a cylinder; a main shaft is arranged inside the cylinder; a bed bracket is arranged on the inner wall of the cylinder; a plurality of layers of plate-style jacket heating devices are arranged on the bed bracket; the main shaft passes through central apertures of each plate-style jacketheating device and is arranged between the top and the bottom of the cylinder; the upper end faces of the plate-style jacket heating devices are material-bearing faces; the main shaft is provided with a plurality of branch arms and material turning plates are arranged on the lower end faces of the branch arms; and the plurality of layers of plate-style jacket heating devices can be at least divided into a high-temperature layer group, an intermediate-temperature layer group, a low-temperature layer group and a cooling layer group from top to bottom. The main-machine adopts the combined heating system adopting both drying and cooling so as to reduce the processes and largely enhance the manufacturing efficiency and the productivity; and simultaneously the drying system can realize the constant vacuum feeding and discharging, solvent recycling and disposal of harmful gas.

Description

Host of hot plate continuous vacuum drying system technical field The invention relates to a main machine of a hot plate type continuous vacuum drying system. Background technique Chinese Patent Literature Publication No.: CN1089351 discloses a multi-layer disk continuous vacuum dryer, which is mainly composed of a shell, a disk, a transmission shaft, a cutter head, a knife holder, a scraper, etc., and uses a combination of a multi-layer disk and a multi-layer scraper , so that the material can be in regular dynamic contact with the heating surface, evenly heated, continuous operation, and can be used in the occasion of drying powder materials. The disadvantage of the above-mentioned prior art is that: the discs of each layer adopt the same drying temperature, and for some easily oxidized materials, low-melting heat-sensitive materials, and non-bonding powders and crystals containing organic solvents or toxic and harmful solvents And amorphous materials, the above-mentio...

Problems solved by technology

The disadvantage of the above-mentioned prior art is that: the discs of each layer adopt the same drying temperature, and for some easily oxidized materials, low-melting heat-sensitive materials, and non-bonding powders and crystals containing organic solvents or toxic and harmful solvents And amorphous materials, the above-mentioned dryer cannot perform continuous vacuum drying, because it cannot solve the problem of anti-oxidation of easily oxidized materials, the problem of dampness and adhesion of low-melting heat-sensitive materials, and it cannot handle the recovery of organic solvents or toxic and harmful solvents.
