Description

Technical Field

[0001] The invention relates to the technical field of raw material adding devices, in particular to a raw material positioning adding device for preparing thickening type concrete containing bentonite. Background Art

[0002] Bentonite-containing thickening concrete refers to concrete in which a certain amount of bentonite is added to the components of conventional concrete. Bentonite has good water absorption and expansion properties and thixotropy, and can increase the viscosity and stability of the concrete mixture.

[0003] At present, a device for adding concrete raw materials is usually used in the preparation process of thickening concrete. However, the addition of concrete raw materials is usually done by directly injecting the raw materials into a mixing barrel through a feed pipe, and then stirring and mixing them through a stirring rod. This method may cause the feed pipe to be clogged due to excessive material discharge when the raw materials are added, and direct addition during the discharge may cause uneven subsequent stirring, affecting the mixing effect. Moreover, the concrete also needs to maintain a certain degree of dryness during the injection and addition process. Excessive moisture may cause the concrete to clump.
