Description

Technical Field

[0001] The utility model relates to the technical field of quick-setting agent production, in particular to a cooling mechanism for producing concrete quick-setting agent. Background Art

[0002] Concrete accelerator is a new generation of high-efficiency multifunctional accelerator scientifically synthesized from inorganic salts and organic polymer materials. It is suitable for shotcrete construction, underwater concrete and leak-proof emergency projects. Concrete accelerator is translucent or slightly yellow liquid in appearance, non-toxic, odorless and non-flammable.

[0003] When producing accelerators, a reactor is usually used to produce accelerators. Workers first feed bottom water into the tank through the feeding port and start the motor at the same time. The motor drives the stirring shaft to rotate. Under stirring, solid raw materials such as hydrated magnesium silicate and inorganic salts are added into the tank through the feeding port. Then, inorganic acid is introduced into the tank through the feeding port. The blades stir the solid raw materials and the inorganic acid. When the solid raw materials and the inorganic acid are stirred and mixed, a chemical reaction occurs to obtain an accelerator. During the production process of the accelerator, the accelerator needs to be cooled.

[0004] In the prior art, conventional cooling mechanisms for the production of quick-setting agents are mostly provided with a water-cooled water jacket on the outside of the tank body for cooling the quick-setting agent. The quick-setting agent near the middle of the tank body needs to consume a lot of time to cool, resulting in poor cooling effect and low cooling efficiency. At the same time, the quick-setting agent is prone to condensation after cooling, and the condensate is easy to clog the drain valve, resulting in unsmooth discharge and affecting normal use.
