Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete preparation, in particular to a concrete admixture compounding and feeding device. Background Art
[0002] At present, admixtures have become the fifth largest component of concrete and are widely used. They are the objective requirement for the development of construction engineering structure and technology. The addition of admixtures is to improve the performance of concrete, improve the quality of the project, reduce the cost of the project, and promote the requirements of new processes. The performance of concrete is determined by the ratio of cement, sand, gravel and water. In order to improve a certain property of concrete, the proportion of raw materials can be adjusted, but this often causes losses on the other hand. For example, in order to increase the fluidity of concrete, the amount of water is increased, but this will reduce the strength of the concrete.
[0003] According to the disclosed concrete admixture compounding and feeding device (publication number: CN20071283U), when admixture compounding is required in the above application, the admixture is added from the hopper. At this time, the admixture falls into the reflux pipe under the action of gravity, and the solution is circulated by continuous extraction through a water pump. The initially mixed solution will continuously circulate and mix with the admixture added later.
[0004] However, in actual use of the above equipment, the admixture enters through the hopper and then cooperates with the water pump to circulate the solution, which is convenient for adding admixtures to the concrete. However, air-entraining agent is an admixture that needs to be added. Since the dosage of air-entraining agent is very small, when it is used, if it is insoluble in water and added directly, the addition amount will be inaccurate. In view of this, we propose a concrete admixture compounding and feeding device. Summary of the invention

[0027] In the present invention, when in use, concrete is stirred by the stirring assembly 2. When an admixture needs to be added, air entraining agent particles are manually put into the hopper 4.
