Description

Technical Field

[0001] The utility model relates to the technical field of bentonite and discloses a sodium modified bentonite alkali adding machine. Background Art

[0002] Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedron. Due to the layered structure formed by the montmorillonite unit cell, there are certain cations, such as Cu, Mg, Na, K, etc., and these cations are very unstable in the interaction with the montmorillonite unit cell, and are easily exchanged by other cations, so it has good ion exchangeability. It has been used in more than 100 departments in 24 fields of industrial and agricultural production abroad, with more than 300 products, so people call it "universal soil". When processing bentonite, alkali needs to be added through alkali adding equipment. Adding alkali can effectively change the internal composition of bentonite, so that the pH value of bentonite can be rapidly increased, thereby improving the various performance indicators of bentonite.

[0003] However, the patents in the prior art have the following disadvantages:

[0004] (1) It is impossible to clean the inside of the mixing tank. After the mixing tank is used, there will be a lot of bentonite left inside, which needs to be cleaned.

[0005] (2) When adding alkali, dust will be generated and cannot be collected.

[0006] (3) It is impossible to transport bentonite, and other equipment is needed to transport bentonite, which is troublesome. Utility Model Content
