Description

Continuous pulping machine set for kaolin

Technical Field

The utility model relates to the technical field of nonmetallic ore dressing machinery, in particular to a kaolin mashing continuous pulp pulping unit.

Background

The main components of the kaolin are minerals such as kaolinite, elbaite, hydromica and quartz sand. In industry, the processing technology and the quality of the raw ore will determine the purpose of the product, and the pulp crushing equipment is common equipment in the kaolin mineral separation technology. When the kaolin is used for concentrating ore to prepare slurry, water is added to enable the kaolin to be dissociated in the form of granular monomers in water, and then the slurry is smashed through stirring, shearing and high-speed rotation in a slurry smashing equipment unit. At present, most of the slurry-crushing equipment for kaolin ore dressing mainly utilizes centrifugal force and shearing motion to crush raw materials when in use, has lower efficiency, cannot fully crush the raw materials, has insufficient crushing degree of the raw materials, and is insufficiently mixed with water after being crushed, the quality of the obtained slurry is not ensured, and the use requirements of different products cannot be met. The Chinese literature with publication number CN206519092U discloses a pulp grinder, which comprises a pulp grinder barrel, stirring blades arranged in the pulp grinder barrel and a pulp outlet pipeline communicated with the pulp grinder barrel; a slurry outlet is formed in the position, close to the bottom, of the slurry tamping barrel, and the position of the stirring fan blade is higher than the slurry outlet; the pulp outlet pipeline comprises a first pulp outlet pipe and a second pulp outlet pipe which are communicated with each other, and the first pulp outlet pipe is communicated with the pulp outlet; the second grout outlet pipe comprises a first end part, a middle part and a second end part which are communicated with each other, wherein the first end part is communicated with the first grout outlet pipe, the middle part is bent upwards, and the second end part extends downwards, so that the second grout outlet pipe forms an arch structure. The technology increases the residence time of the mashing raw material by maintaining the height of the liquid level in the mashing barrel, thereby improving the mashing effect, but since the technology cannot perform the classified mashing and running operation in one mashing barrel and the concentration of the mashing is difficult to be ensured to be about consistent each time, the mashing effect, the speed and the concentration stability can be further improved.

Therefore, in view of the problems in the prior art, there is a need to provide a technique for improving the mashing efficiency, improving the mashing effect, and improving the multiple stability of the slurry concentration.
