Description

Technical Field

[0001] The utility model relates to the technical field of quick-setting agent production, in particular to a reaction kettle for concrete quick-setting agent with a heating and heat-insulating double-layer structure. Background Art

[0002] Accelerators are additives added to concrete to make it set and harden quickly. The main types are inorganic salts and organic substances. Powdered solids, whose dosage accounts for only 2% to 3% of the cement in concrete, can make the concrete set within 5 minutes, and the accelerator sets within 12 minutes. This can achieve the purpose of rapid setting of concrete in emergency repairs or shafts. It is an indispensable additive in the shotcrete construction method. Their function is to accelerate the hydration and hardening of cement, and form sufficient strength in a very short time to meet the requirements of special construction.

The heat insulation sleeve is arranged outside the tank body to prevent the temperature of the material from decreasing, and serves the purpose of heat preservation during the reaction, reducing heat loss. The air inlet is arranged at the bottom of the heat insulation sleeve, and the air outlet is arranged at the top of the heat insulation sleeve to ensure that the temperature gas fills the entire heat insulation sleeve, further improving the heat preservation effect, thereby ensuring that the material reaction temperature fluctuates within the standard range.
