Description

Technical Field

[0001] The invention relates to the technical field of concrete admixture production, in particular to a proportioning device for concrete admixture production. Background Art

[0002] In the production process of concrete admixtures, the core position of the proportioning device cannot be ignored. The main responsibility of this device is to mix various admixture components to ensure the quality and performance of the final product. However, traditional proportioning devices mostly use manual or simple mechanical mixing, which has significant deficiencies in efficiency and uniformity.

[0003] Specifically, due to its single mixing method, it is often difficult to ensure the uniform distribution of admixtures in the proportioning and mixing bin. Especially when mixing a large amount of materials, it is easy to have local concentrations that are too high or too low, which not only affects the quality of concrete, but may also have an adverse effect on the performance of concrete. The shortcomings of the mixing method of the traditional proportioning device directly lead to the problem of uneven mixing of concrete admixtures. During manual mixing or simple mechanical mixing, due to the uncontrollability of factors such as mixing intensity, speed and direction, the distribution of admixtures in the proportioning and mixing bin is difficult to achieve an ideal state. This uneven distribution state, in turn, leads to differences in local concentrations of concrete. Therefore, in order to improve the mixing efficiency and uniformity of concrete admixtures, a proportioning device for concrete admixture production is needed. Summary of the invention

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a proportioning device for concrete admixture production, which has the following beneficial effects:

[0022] 1. When the proportioning device for concrete admixture production moves downward and rotates through the inclined plate, the cover plate at the upper position will be opened upward by the force of the concrete admixture in the proportioning mixing bin, so that the concrete admixture in the lower space of the proportioning mixing bin can enter the upper space.

[0025] 4. The proportioning device for concrete admixture production has higher mixing efficiency through the admixture mixing components provided. The rapid rotation of the motor and the up and down movement and rotation of the inclined plate enable the admixture to reach a uniformly mixed state in a short time.
