Description

Technical Field

[0001] The invention relates to the technical field of material preparation equipment, in particular to a device for preparing a bentonite-reinforced slag-fixing sand composite material. Background Art

[0002] Natural sodium-based bentonite and slag from large coal mine stripping layers can be used as sand-fixing materials. After the bentonite and slag are processed and compounded, they can be laid or sprayed on the sand to harden the sand. At the same time, they can also have the effects of high temperature resistance, cold resistance, and rain protection. The preparation of the composite material is similar to the preparation process of mixing cotton felt and cement or mahjong mats, and then the composite material can be mixed to facilitate laying and spraying.

[0003] Considering that the sand-fixing materials need to be stirred and mixed during the composite process, and multiple operation processes need to be carried out on the sand-fixing materials during the preparation process, the corresponding material preparation equipment is needed for coordinated preparation. Therefore, some composite material preparation devices with special structures and functions can be used.

[0004] Generally, during the preparation process of traditional preparation equipment, the large particles of bentonite or coal mine stripping layer slag inside are very likely to affect the appropriate amount of use of the composite sand-fixing material. When the content of large particles of soil is relatively high, it is very easy to cause the outer surface of the sand body to bulge during use, which in turn causes different degrees of mixing between the material and the sand body, thereby affecting the overall sand-fixing effect. Large particles of soil can be used for paving roads, etc. If they are used directly as sand-fixing materials, not only will the effect be reduced, but it will also cause waste. In the process of sand fixation, a variety of materials need to be added for mixing. If these materials are left standing, it is very easy to cause stratification between the materials, thereby affecting the overall sand-fixing effect and reducing the degree of mixing of the materials, which is very inconvenient.

[0005] In summary, it is necessary to propose a device for preparing bentonite-reinforced slag-fixing sand composite materials to solve the above problems. Summary of the invention
