Description

Technical Field

[0001] The utility model belongs to the technical field of raw material proportioning, in particular to a raw material proportioning device for calcium carbonate processing products. Background Art

[0002] Calcium carbonate is an inorganic compound with the chemical formula CaCO 3 Calcium carbonate is a major component of limestone and marble. Calcium carbonate is usually white crystals, odorless, basically insoluble in water, and easily reacts with acid to release carbon dioxide. It is one of the most common substances on Earth, existing in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and has a wide range of industrial uses.

[0003] When producing calcium carbonate processed products, a raw material proportioning device is required to mix calcium carbonate and other raw materials. In the prior art, Chinese patent CN220780114U discloses a raw material proportioning device for calcium carbonate processed products, including a proportioning tank, a middle portion of the bottom surface of the proportioning tank is fixedly equipped with an anti-wall-hanging stirring structure, the upper end of the anti-wall-hanging stirring structure extends into the proportioning tank, and the upper end of the proportioning tank is fixedly connected with a quantitative proportioning feeding device; the proportioning tank is used as a container, the anti-wall-hanging stirring structure is used to stir the raw materials, and the raw materials can be effectively prevented from hanging on the wall, and the solid raw materials and liquid raw materials are quantitatively proportioned by the quantitative proportioning feeding device, the solid raw materials are weighed by the weight of the calcium carbonate raw material temporary storage tank through a weighing sensor, and the controller is used to discharge a certain amount of solid raw materials each time, and the solid raw materials are crushed through a feeding pipe with a crushing function and enter the proportioning tank; the quantitative liquid inlet mechanism quantitatively supplies the liquid raw materials through a metering pump, accurately controls the amount of raw material added, and improves work efficiency.

[0004] However, the raw material proportioning device for calcium carbonate processing products provided in the above technical solution still has many disadvantages in actual use. For example, the material is conveyed through a pipeline with a crushing mechanism, but there is no filtering mechanism in the pipeline, so that it is impossible to determine whether the calcium carbonate particles meet the mixing requirements after the raw materials are crushed. In addition, when the feeding speed is too fast, the calcium carbonate raw materials are easily caused to flow into the mixing device without being completely powdered, thereby affecting the quality of the raw material proportioning.
