Abstract

The invention relates to a biconical rotary vacuum drying system, which comprises a biconical rotary vacuum drying main machine, a condenser, a gas-liquid separator, a vacuum pump, an oil pump, a hot oil tank, a vacuumizing pipe, an oil supply pipe and an oil return pipe, wherein the vacuumizing pipe extends into a cylinder body of the biconical rotary vacuum drying main machine from the inner cavity of a driving half shaft and the pipe hole of a driving shaft base; the oil supply pipe extends into an oil inlet cavity from the inner cavity of a driven half shaft and a pipe hole on a baffle; and two built-in oil supply branch pipes which are arranged horizontally on front and back sides are arranged on the middle part of a clamp sleeve of the cylinder body and are communicated with an oil inlet cavity of a driven shaft base. By the biconical rotary vacuum drying system, heat conducting oil can be distributed to integral clamp sleeve space uniformly to ensure the uniformity of clamp sleeve heating, the problem that biconical rotary vacuum drying is 'semi-hot and semi-cold' for a long term is solved, the quality of products and the work efficiency are improved, and energy is saved. In the biconical rotary vacuum drying system, solvents are recovered by a gas condenser and a liquid separator.

Description

technical field

[0001] The invention relates to a double-cone rotary vacuum drying system. Background technique

[0002] Chinese Patent No. 200520073364.9 utility model patent specification discloses a double-cone rotary vacuum dryer, including tank, left arm tube, right arm tube, water inlet pipe, water outlet pipe, vacuum tube, static ring, moving ring, Bearings and sprockets, top springs that can automatically compress the sealing material are provided at the outer ends of the left and right arm barrels, and wear-resistant, sealing Good performance PTFE gasket. The heat-conducting medium of the above-mentioned double-cone rotary vacuum dryer enters the jacket from one side, and the temperature of the heat-conducting medium drops in the second half, and the jacket becomes "half hot and half cold", resulting in uneven moisture and fineness of the finished product, affecting the quality of the product. quality and drying efficiency.
