Abstract

The invention relates to mechanical equipment in a light calcium production process and particularly relates to a high-temperature, energy-saving and full-automatically controlled quick lime slaking device. The quick lime slaking device comprises a tank body, a stirring mechanism and an automatic control system, wherein the stirring mechanism comprises a power part and a stirring part which are mutually connected, and the stirring part is arranged in the tank body; and a water injection hole and a raw material filling hole are formed in the top of the tank body, a slurry outlet is formed in the bottom of the tank body, a heating device is arranged at the water injection hole, and a grinding device is arranged at the raw material filling hole. An automatic control system controls the working and stopping of the heating device, the grinding device and a power part, so that the automation degree of the quick lime slaking device is relative high, the slaking reaction is accelerated, and the energy consumption of the device is reduced; and meanwhile, the slaking reaction time can be set by virtue of a time control part and is therefore adjustable.

Description

technical field [0001] The invention relates to mechanical equipment in the production process of light calcium, in particular to a high-temperature, energy-saving, automatic control quicklime digestion device. Background technique [0002] Light calcium is light calcium carbonate, also known as precipitated calcium carbonate. After mixing limestone and white coal in a certain proportion, it is calcined at high temperature, digested with water, carbonized with carbon dioxide, and then centrifugally dehydrated, dried, cooled, crushed, and sieved. The mixture of limestone and white coal is calcined at high temperature to produce quicklime, that is, calcium oxide, and the quicklime is digested by water to produce slaked lime, that is, calcium hydroxide. At present, the quicklime digestion device is generally used in the industry for digestion reaction. A certain amount of quicklime and a certain amount of water are added to the quicklime digestion device, and an agitator is ins...
