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, allowed to settle for 5 minutes, and checked that the Baume degree of the liquid was not lower than 33.5 Be'. If the Baume degree did 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 magnes...

Embodiment 2

[0025] Embodiment 2, a kind of production technique of magnesium chloride particle, its step is as follows:

[0026] (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: 1400:600 kg / L , stirred for 15 minutes, allowed to settle for 10 minutes, and checked that the Baume degree of the liquid was not lower than 33.5Be′. If the Baume degree did not meet the requirements, add an appropriate amount of crystalline magnesium chloride until the liquid Baume degree reached the requirement;

[0027] (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;

[0028] (3) Precision filtration: After the primary filtration liquid magnesiu...

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, allowed to settle for 8 minutes, and checked that the Baume degree of the liquid was not lower than 33.5 Be′. When the Baume degree did 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;

[0034] (3) Precision filtration: After the initial filtration liquid mag...

Abstract

The invention discloses a production process of magnesium chloride granules. The production process comprises the following steps of: crushing crystallized magnesium chloride, then, placing the crushed magnesium chloride into a dissolving tank, stirring the crushed magnesium chloride, then, standing for settlement, inspecting the baume degree of the liquid not to be lower than 33.5Be', and primarily filtering the liquid in the dissolving tank to obtain primary filtrate magnesium chloride; naturally settling the primary filtrate magnesium chloride for at least three days, then, sequentially placing the primary filtrate magnesium chloride into a two-effect separator and a one-effect separator to carry out steam-liquid separation to obtain liquid magnesium chloride; and delivering the liquid magnesium chloride to a dust-free pelleting chamber through a pipeline to pellet to obtain finished products of the magnesium chloride granules. The method is advanced in process design, strong in operability, controllable in process parameter and capable of realizing large-scale industrial production; the prepared product is high in purity and capable of meeting the requirement of a high-quality product; the magnesium chloride granules are high in dissolving speed and clear, transparent and free of impurities after being dissolved; and an automatic production line is adopted, and the product is high in stacking density and not easy to air slake.
