Description

Technical Field

[0001] The utility model relates to the field of mixers, in particular to a mixer with a raw material premixing function. Background Art

[0002] A mixer is a device for uniformly mixing raw materials. When mixing, various raw materials need to be directly placed in the mixer and continuously stirred. In order to produce a mixture with accurate ingredients, a small amount of liquid for some components is added and metered. The traditional method uses manual weighing and then puts it into the mixer, which leads to high labor intensity and the efficiency of the mixer cannot be effectively exerted. In order to solve the above problems, a mixer with a liquid metering system has emerged, such as the liquid metering system and mixer with application number 2017211469820, which includes a bucket body, a feeding pipeline that can convey liquid to the bucket body, and a discharge pipeline installed at the bottom of the bucket body for unloading. The bucket body includes an inner wall and an outer wall, a partition through which liquid can flow is formed between the inner wall and the outer wall, and a device for heating the bucket body is provided on the bucket body. A heating unit for the liquid in the bucket, the heating unit includes a heating pipeline, a control valve for controlling the switch of the heating pipeline, and a heater for heating the liquid flowing through the heating pipeline, the heating pipeline is connected to the partition of the bucket body, the feeding end of the feeding pipeline is divided into three branch pipelines, namely a rough metering pipeline, a fine metering pipeline and a circulation pipeline, the ends of the rough metering pipeline and the fine metering pipeline extend into the bucket body, the end of the circulation pipeline extends into the liquid barrel, and the end of the unloading pipeline of the liquid metering system extends into the mixing host; when used, by controlling the control valves on each pipeline, the specific pipeline into which the liquid flowing into the feeding pipeline enters is further adjusted, thereby realizing rough metering, fine metering and circulation of the liquid, so that the liquid enters the mixer for sufficient mixing.

[0003] However, although the above-mentioned mixer solves the problem of automatic metering of trace liquids, some raw material components still have trace powders. The above-mentioned mixer still needs to use manual measurement and then directly add the trace powders to the mixer for stirring. If the trace powders are directly added to the stirring material, it is easy for the trace powders to mix with the local stirring material, or the trace powders will mix with part of the water in the raw materials and cause the trace powders to agglomerate together, making it impossible for the trace powders to be mixed evenly with the overall stirring material; furthermore, if some raw material components also have solid materials, if the solid materials are directly added to the raw materials, the solid materials will not dissolve in the raw materials in time, and it is still not easy to mix the solid materials with the overall stirring material evenly.
