Description

Slag removal device of calcium carbonate thick liquids

Technical Field

The utility model relates to the technical field of slag removal equipment of calcium carbonate slurry, in particular to a slag removal device of calcium carbonate slurry.

Background

Calcium carbonate is widely applied in the industrial field, but the ore is required to be crushed layer by layer to be finely ground in order to improve the added value of the calcium carbonate, so that the calcium carbonate can be applied to the high added value fields such as papermaking, building coating or toothpaste, but the calcium carbonate is not mixed together with a high-hardness grinding medium in grinding, and the calcium carbonate is ground in a high-speed rotating wet mill container.

At present, calcium carbonate with sufficient fineness of ground particle size is required. In addition, the wet grinding is generally carried out in the process to meet the requirement of environmental protection, however, when the calcium carbonate slurry is separated from the grinding medium after grinding, the grinding medium is repeatedly collided with the calcium carbonate and high-speed rotating grinding stirring equipment in a container, and the grinding medium with high hardness is also partially crashed, cracked and worn in the process of collision and kneading. These crushed, worn, broken grinding media are carried along with the ground calcium carbonate slurry into the slurry cleaner.

The existing grinding media and slurry with different specific gravities are utilized to settle at the bottom of the conical slag remover under the centrifugal force action of the conical slag remover, the slag discharging valve is opened periodically to discharge the fine grinding media and impurities with large specific gravities, and the good slurry flows out from the top of the conical slag remover to the next procedure, and is further filtered by the pressure screen to remove the impurities. However, because the concentration of the wet-milled calcium carbonate slurry is as high as 75%, some finely-divided grinding media cannot be completely separated by gravity under the action of centrifugal force, and part of finely-divided grinding media are wrapped and clamped by the high-concentration slurry together into the pressure screen filter.

Since the grinding media are synthetic zirconium beads of rare metal cerium or yttrium with very high hardness, the hardness of the grinding media exceeds that of iron, and therefore, if the grinding media enter a pressure screen in the next working procedure, the grinding media with high hardness are clamped between a rotating pressure screen scraper and a pressure screen drum, so that the screen drum is severely worn out and worn out, the screen use time is short, even the screen drum is worn out and the screen drum is scrapped, so that the screen drum needs to be frequently disassembled and cleaned manually, the grinding media clamped in the screen seams are removed, the time and the labor are wasted, the cost are increased, the grinding efficiency is reduced, and even the machine is stopped.
