Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, and more specifically, to a quantitative feeding device for solid chemical raw materials. Background Art

[0002] In the process of chemical production, it is usually necessary to add corresponding solid raw materials. Before adding the raw materials, they need to be weighed. When it comes to complex production processes, multiple raw materials are often required. Therefore, it takes a lot of time to weigh the multiple raw materials in turn. In addition, in the production process, in order to avoid cross contamination between raw materials, a separate weighing area is usually configured for each raw material. After weighing, the batch raw materials need to be transferred from the weighing area to the processing area, which also takes a certain amount of time. Therefore, the process of weighing and transferring the raw materials separately will lead to a decrease in the overall efficiency of chemical production. Utility Model Content
