Abstract

The invention relates to a valve device of a dehumidifying and crystallizing system. The dehumidifying and crystallizing system comprises a bracket, a crystallizing kettle arranged on the bracket, a hopper arranged at the upper part of the crystallizing kettle and a feeding channel connecting the crystallizing kettle and the hopper. The valve device comprises a first valve arranged at the upper part of the feeding channel. The valve device further comprises a second valve arranged at the lower part of the feeding channel, wherein the second valve is provided with a dust-removing device. According to the invention, the dust-removing device is arranged at the second valve, so that dust in materials can be quickly and conveniently removed without influencing the normal use of the valves.

Description

technical field [0001] The invention belongs to the field of crystallization equipment, and in particular relates to a valve device of a dehumidification crystallization system. Background technique [0002] At present, the dehumidification and crystallization system includes a crystallization tank, a hopper arranged on the upper part of the crystallization tank, a feeding channel connecting the crystallization tank and the hopper, and a valve arranged on the feeding channel. [0003] The valve is used to control the material in the hopper to enter the crystallization tank, but the material is often mixed with fine powdery dust, if this part of dust is not removed, it will inevitably affect the crystallization material in the crystallization tank. Contents of the invention [0004] In order to overcome the defects of the prior art, the object of the present invention is to provide a valve device of a dehumidification and crystallization system with dust removal function. ...
