Abstract
Description
Technical Field
[0001] The invention relates to the technical field of concrete mixing stations, in particular to a dust suppression powder tank assembly used in concrete mixing stations. Background Art
[0002] Concrete mixing station is a combined device used for centralized mixing of concrete, also known as concrete prefabrication plant. It is mainly composed of five systems including mixing host, material weighing system, material conveying system, material storage system and control system, as well as other ancillary facilities. As the concrete mixing station has a high degree of mechanization and automation, its productivity is also very high, and it can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, power, bridge and other projects with large concrete engineering volume, long construction period and concentrated construction sites.
[0003] Concrete mixing plants usually need to store aggregates, powders, water and liquid admixtures required for concrete production. Aggregates are usually piled in the open air, powders are stored in fully enclosed steel silos or tanks, and water and liquid admixtures are stored in steel containers.
[0004] However, the current technology has the following shortcomings:
[0005] 1. When using a powder tank to store powder for a concrete mixing plant, flying dust will often form in the powder tank after the powder is fed into the powder tank. In order to prevent smoke and dust from spreading during feeding, a dust-proof net is usually covered on the powder tank. However, the dust-proof and dust-suppression effect is often poor, which in turn affects the working environment of the concrete mixing plant;
[0006] 2. When using the dust-proof net for dust-proof operation, a lot of powder will often accumulate on the dust-proof net. When there is too much powder, it is often difficult to clean up. At the same time, it will cause the dust-proof net to be blocked, affecting the dust-proof net's suppression effect on the powder. At the same time, the common dust-proof net is often not easy to replace, resulting in poor use of the powder tank, which in turn affects the use of the concrete mixing station;
[0007] 3. When discharging the powder inside the powder tank, the inner wall of the powder tank tends to absorb more powder, which makes it difficult to discharge the powder and leads to low utilization rate of the powder, thereby increasing the production cost of concrete, resulting in poor production effect of the concrete mixing station and failure to meet people's usage needs. Summary of the invention
