Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete processing, in particular to a concrete sand and gravel pre-homogenization device. Background Art
[0002] In the concrete production process, sand and gravel are important raw materials, and their quality and uniformity have a decisive influence on the performance of concrete. In order to improve the quality of concrete, people often use mixing devices to mix and mix sand and gravel of different qualities to achieve pre-homogenization of sand and gravel. However, existing mixing devices have some problems in the sand and gravel pre-homogenization process, especially in the feeding link, where these problems are particularly prominent.
[0003] Specifically, the existing mixing device usually needs to be temporarily stopped during loading in order to add new sand and gravel into the mixing bin. Such frequent stops not only reduce the efficiency of sand and gravel pre-homogenization, but also prolong the overall pre-homogenization time of sand and gravel. Because each stop will cause the distribution state of sand and gravel in the mixing bin to change, and re-mixing and homogenization are required. In addition, frequent stops will increase equipment wear and energy consumption, and reduce the service life of the equipment.
[0004] More importantly, this feeding method cannot achieve continuous production and processing operations. In modern concrete production, continuous and automated production methods have become the mainstream trend of industry development. However, since the existing mixing device needs to stop when feeding, the entire production process cannot be carried out continuously, which seriously affects production efficiency.
[0005] Therefore, it is necessary to improve and innovate the existing concrete sand and gravel pre-homogenization device to solve the problem that the mixing device needs to stop when loading, improve the efficiency of sand and gravel pre-homogenization, and realize continuous production and processing operations.
