Problems solved by technology

The main product of traditional snowmelt is sodium chloride, but because of the pollution to the environment and the reason that it cannot be used in alpine regions, the amount of use is gradually decreasing
At present, although the salt-magnesium and salt-calcium deicing agents commonly used in many countries have quick-acting and long-lasting characteristics, their fluidity is poor, the mixing uniformity of the machine is slightly poor, and they contain more sulfate ions. Road shoulders, bridges, etc. are also corroded, so this product is still not ideal

Embodiment 1

[0017] Use a bucket elevator to send 5 tons of magnesium chloride hexahydrate into the melting tank and heat it to 145°C, and all the magnesium chloride hexahydrate will melt. Drive the magnesium liquid into the mixing tank with a submerged pump, and send 5 tons of sodium chloride into the mixing tank with a bucket elevator, and start stirring and mixing for 0.5 hours to make the slurry evenly mixed. Use the feeding pump to pump the slurry to the granulation tower, use the rotating granulation head, and granulate with the feeding. The liquid droplets are cooled into spherical particles in the tower, and sent to the sieving machine outside the tower for screening by the scraper trigger. That is, qualified products are obtained, and unqualified products are returned to the mixing tank for re-melting and granulation.

Abstract

The compound snow-melting antifreezer is mixture of spherical NaCL 0-60%, MgCl2.6H2O 0-98 % and CaCl2.2H2O 0-98%. It has excellent snow-melting, antifreezing, defreezing and dedusting effect as well as the features of unique shape, good flowability and homogeneous mixing. It is used mainly for smelting snow, preventing frost, defreezing, dedusting road, etc. and is suitable for large-scale mechanical operation.

Description

technical field [0001] The invention relates to the manufacture of a compound snow-melting antifreeze agent, which mainly utilizes the characteristics of part of inorganic salts, heats and melts it, and regranulates it to become a spherical snow-melting antifreeze agent. Background technique [0002] Snowfall has a serious impact on people's production and life. Therefore, countries are paying more and more attention to snowmelting operations. The main product of traditional snowmelt is sodium chloride, but because of the pollution to the environment and the reason that it cannot be used in alpine regions, the amount of use is gradually decreasing. At present, although the salt-magnesium and salt-calcium deicing agents commonly used in many countries have quick-acting and long-lasting characteristics, their fluidity is poor, the mixing uniformity of the machine is slightly poor, and they contain more sulfate ions. Road shoulders, bridges, etc. are also corroded, so this pro...
