Dense soda ash high-efficiency crystallization production device

Abstract

The invention belongs to the field of chemical low-salt dense soda ash equipment, and particularly relates to a dense soda ash high-efficiency crystallization production device, a motor is started torotate to drive a stirring belt to rotate, a gas flow generated by the rotation of a gas in a crystallization furnace along with the stirring belt spirally ascends, the gas on the upper side of the crystallization furnace extrudes a pressure valve on a second fixing plate through an one-way valve, the gas pressure is increased, at the moment the gas pressure breaks down the pressure valve, the gaspressure pushes a sliding plate and a first pressure plate on the upper side of the crystallization furnace to slide downwards, and a spring is stretched; steam in a steam chamber enters the crystallization furnace, the gas pressure is increased, at the moment the gas pressure breaks down a pressure valve at the lower side of the crystallization furnace, the gas pressure pushes a sliding plate and a second pressing plate on the lower side of the crystallization furnace to slide upwards, the spring is stretched, the spring rebounds to drive the sliding plate to slide back, and the sliding plate, the first pressing plate and the second pressing plate slide back and forth to stir crystal slurry in the crystallization furnace, so that the slurry is continuously circulated, and crystal grainsgrow continuously.

Description

technical field [0001] The invention belongs to the field of chemical low-salt heavy soda ash equipment, and in particular relates to a high-efficiency crystallization production device for heavy soda. Background technique [0002] The scientific name of soda ash is sodium carbonate, also known as soda and soda ash. It is a white powder or drop, and its chemical formula is Na 2 CO 3 , relative molecular mass 105.989. There are two main types of soda ash products, namely heavy soda ash (heavy ash) and light soda ash (light ash); the difference in their specifications mainly lies in the difference in physical properties, such as bulk density, particle size and shape, etc. Generally, the density of light soda ash is 0.5~0.6g / ml; the density of heavy soda ash is 1.0~1.2g / ml. [0003] The main production methods of heavy soda ash are respectively solid-phase hydration method, liquid-phase hydration method and extrusion method using light soda ash as raw material; evaporative c...
