A vertical vacuum drying mixer for cemented carbide production

Abstract

The invention discloses a vertical vacuum drying mixer for cemented carbide production, which comprises a column, a mixing cylinder is fixedly installed on the upper end of the column, a lower hopper is fixedly installed on the lower end of the mixing cylinder, and the lower hopper A discharge pipe is installed at the lower end, a feed hopper is installed in the middle of the front of the mixing barrel, and a control valve is installed on the lower hopper and the feed hopper; water inlet and outlet pipes are installed in the middle of both sides of the mixing barrel; The upper end of the mixing barrel is provided with a vacuum pump communicating with the inner upper end of the mixing barrel. The beneficial effect is that: the vertical vacuum drying mixer for cemented carbide production according to the present invention can effectively prevent the air filter element from being blocked by wet cemented carbide powder, and ensure that moisture can pass through the air filter element quickly. Drain away, so it can be completely dried without extending the drying time. Compared with the traditional vacuum drying mixer, the drying production efficiency is high, the drying time is short, and the power consumption is low.

Description

technical field [0001] The invention relates to the field of cemented carbide production, in particular to a vertical vacuum drying mixer for cemented carbide production. Background technique [0002] In the production process of cemented carbide, when the alloy raw material powder is uniformly refined by the stirring ball mill, it is necessary to add liquid paraffin to the powder for mixing. Since the liquid paraffin contains a large amount of water, the mixed powder material needs to be dried in a vacuum. Meet the needs of compression molding and vacuum sintering. [0003] At present, for the vacuum drying of cemented carbide powder, a vacuum drying mixer is generally used for drying while stirring. Material barrel and support frame, the left and right ends of the mixing barrel are respectively equipped with left and right rotating shafts, the mixing barrel is a double-cone structure, the inner cavity of the mixing barrel is provided with interlayers, left and right rotat...
