Description

Technical Field

[0001] The utility model relates to the technical field of bentonite alkali addition, in particular to a sodium modified bentonite alkali addition device. Background Art

[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. During processing, it needs to be alkali-added by alkali-adding equipment to change the internal composition of bentonite, so that the pH value of bentonite can be rapidly increased, thereby improving various performance indicators of bentonite.

[0003] When using the existing sodium modified bentonite alkali adding device, the alkali material is usually directly added into the stirring device and stirred and mixed with the sodium modified bentonite. However, in actual use, we found that directly stirring all the alkali material and bentonite requires a lot of mixing time. At the same time, when the alkali material is added into the stirring mechanism, some of the alkali material will remain on the inner wall of the feed pipe. In order to reduce production costs, the staff need to manually scrape off the alkali material, which increases the workload of the staff and easily causes the alkali material dust to fly. Therefore, how to solve these problems is what we need to consider. Utility Model Content
