Description

Technical Field

[0001] The present invention relates to the technical field of material mixing equipment, and in particular to a mixing device for producing chemical raw materials. Background Art

[0002] Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. The main raw materials of inorganic chemical products are chemical minerals containing sulfur, sodium, phosphorus, potassium, calcium, etc. (see inorganic salt industry) and coal, oil, natural gas, air, water, etc.;

[0003] In the process of chemical raw materials production, the mixing of chemical raw materials and additives is involved. In this process, a mixer is needed to mix the additives and chemical raw materials.

[0004] The existing mixers have a simple structure, and most of them use stirring rollers to stir the mixed materials. The stirring effect is relatively simple. The driving of the stirring rollers causes the liquid chemical raw materials to move in a simple manner, resulting in a poor mixing effect.
