Problems solved by technology

[0002] In the prior art, the magnesium chloride produced by the magnesium chloride production process is mostly magnesium chloride flakes. This kind of magnesium chloride flakes has low content, many impurities, and slow dissolution rate, which affects the use efficiency and causes prolonged working hours. After dissolution, there are impurities, which need to be precipitated and filtered.
And most of them are fully manual production, manual weighing and packaging, low production efficiency
The product has edges and corners, and it is easy to break the package during transportation. The product has a large area and cannot be mixed evenly with other products.

Embodiment 1

[0019] Embodiment 1, a kind of production technique of magnesium chloride particle, its steps are as follows:

[0020] (1) Crystal dissolution: pour water into the dissolution tank, open the electric valve; crush the crystalline magnesium chloride with a pulverizer, and put it into the dissolution tank through the conveyor belt. The input weight ratio of crystalline magnesium chloride and water is: 1300:600 kg / L , stirred for 10 minutes, left to settle for 5 minutes, and checked that the Baume degree of the liquid was not lower than 33.5Be. If the Baume degree could not meet the requirements, add an appropriate amount of crystalline magnesium chloride until the liquid Baume degree reached the requirement;

[0021] (2) Preliminary filtration: perform primary filtration on the liquid in the dissolution tank to remove impurities and precipitates, and obtain primary filtered liquid magnesium chloride;

[0022] (3) Precision filtration: After the primary filtration liquid magnesium...

Embodiment 3

[0031] Embodiment 3, a kind of production technology of magnesium chloride particle, its steps are as follows:

[0032] (1) Crystal dissolution: pour water into the dissolution tank, open the electric valve; crush the crystalline magnesium chloride with a pulverizer, and put it into the dissolution tank through the conveyor belt. The input weight ratio of crystalline magnesium chloride and water is: 1350:600 kg / L , stirred for 12 minutes, left to settle for 8 minutes, and checked that the Baume degree of the liquid was not lower than 33.5Be. If the Baume degree could not meet the requirements, add an appropriate amount of crystalline magnesium chloride until the liquid Baume degree reached the requirement;

[0033] (2) Preliminary filtration: perform primary filtration on the liquid in the dissolution tank to remove impurities and precipitates, and obtain primary filtered liquid magnesium chloride;

Abstract

The invention provides a production process of magnesium chloride granules. The process comprises the following steps of: crushing crystallized magnesium chloride and then adding into a dissolving tank, stirring and then standing for precipitation, detecting that the baume degree of the liquid is not lower than 33.5Be, and preliminarily filtering the liquid in the dissolving tank to obtain preliminarily filtered liquid magnesium chloride; naturally precipitating the preliminarily filtered liquid magnesium chloride for at least three days, and then adding into two precise filters in turns for precise filtration to obtain liquid magnesium chloride; adding the liquid magnesium chloride into a preheater for preheating, and then entering a two-effect separator and a one-effect separator in turns for vapor-liquid separation to obtain solid magnesium chloride; and conveying the solid magnesium chloride to a dust-free granulating chamber through a pipe, and granulating by a granulator to obtain the finished magnesium chloride granules. The process has the characteristics that the process design is advanced, the operability is good, the process parameter is controllable, and the industrial production can be realized; the prepared product has high purity and can meet requirements of a high-grade product; the dissolution is fast in speed, the liquid is clear and transparent without impurities after the dissolution; and an automatic flow line is adopted, and the product is large in bulk density and unlikely to deliquesce.
