Description

Technical Field

[0001] The utility model relates to the technical field of recycled concrete production equipment, in particular to an activation device for concrete production. Background Art

[0002] Concrete is the most widely used building material, but the manufacture of concrete consumes a lot of natural resources, and all manufactured concrete will be demolished sooner or later, resulting in a large amount of concrete waste. These disadvantages make concrete have a more serious negative impact on the environment. Based on this, a recycled concrete technology has emerged to solve the problem of waste pollution of waste concrete. It can realize the recycling and reuse of a large amount of waste concrete. Since the performance of recycled aggregates is inferior to that of natural aggregates and will have an adverse effect on many properties of recycled concrete, it is necessary to use activation devices for concrete production to improve the performance of recycled aggregates and improve the quality of recycled concrete.

[0003] Since the activation device for concrete production often assists in realizing the immersion reaction between the recycled aggregate and the acid used for activation during actual operation, after completing one immersion reaction, the aggregate, reaction liquid and slag will be mixed together and not easy to be classified and collected, which is not conducive to the recycling of materials. Moreover, it is not easy to drain the aggregate, affecting the processing quality. This leads to low functionality of the device and can no longer meet people's needs. For this reason, we propose a new type of activation device for concrete production to solve the above-mentioned problems. Utility Model Content
