Biconical rotary vacuum drying main machine

Abstract

The invention relates to a biconical rotary vacuum drying main machine, which comprises a cylinder body, wherein 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; oil return holes are formed at the positions, which are away from the oil inlet ends of the built-in oil supply branch pipes, at upper and lower ends of the clamp sleeve of the cylinder body; built-in oil return branch pipes which are arranged on upper and lower parts respectively are arranged in an insulating layer of the cylinder body; one end of each of the built-in oil return branch pipes is connected with a corresponding oil return hole on the clamp sleeve, and the other end of each of the built-in oil return branch pipes is inserted into an oil return cavity of the driven shaft base; a gap between an oil supply pipe and the inner wall of a driven half shaft serves as an oil return channel; and one end of the oil return channel is communicated with the driven shaft base, and the other end of the oil return channel is connected with an oil return pipe. By the biconical rotary vacuum drying main machine, 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.

Description

technical field [0001] The invention relates to a double-cone rotary vacuum drying host. 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. During the drying process of lithium iron...

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

During the drying process of lithium iron phosphate as a battery material, the shape of the material changes greatly from liquid to paste to powder, and the drying of lithium iron phosphate requires controlling the final moisture of the product to be low and the purity high. The above equipment is not suitable. Drying of lithium iron phosphate material
