Description

Material turning and desliming machine

Technical Field

The utility model relates to a blocky anhydrous desliming technology especially relates to an anhydrous desliming machine with stirring function.

Background

The block desliming machine is widely applied to desliming operation of blocks such as clay-containing stacking ores, construction wastes, root block plants and the like. The current methods for desliming lumps are mainly two of the following:

one is to screen out the clay adhered on the blocks by adopting a vibrating screen,

another method is to wash off the adhered soil on the blocks by a cylindrical screen or a spiral ore washer by using a water washing method.

In the first method, the vibrating screen can remove clay contained in the blocks with small water content and loose clay, and when the water content is high, the clay blocks the screen to affect the screening effect, so the common method is to dry the clay, then mechanically break up the clay, and then use the vibrating screen for screening. Since this method requires drying a large amount of soil, consumes a large amount of energy, and causes environmental pollution, the cost of the desliming treatment is also high.

The second method is adopted, the washing method is also a commonly used block desliming method, but a large amount of slurry generated after washing causes serious pollution to the environment, equipment investment is needed for drying treatment of the slurry, a large amount of cost is consumed, and the current environmental protection departments of various countries in the world limit a unit without slurry treatment capacity to adopt a washing process.

A large amount of accumulation-type bauxite exists in Guangxi, Guizhou, Yunnan and other places in China, the total reserve of the accumulation-type bauxite reaches more than 10 hundred million tons, the exploitation amount of Guangxi is large, the Guangxi basically adopts a washing process to dig out and transport the accumulation-type bauxite and soil in a mountain ditch to an ore washing plant, the ore is deslimed and washed out through the operations of crushing, a cylindrical ore washing machine and a spiral ore washing machine, the washed-out slurry is discharged into a special tail mud dam, the ore digging part is seriously stony desertified, the natural environment is seriously damaged, and the soil is abandoned in the tail mud dam to form environmental disasters.

At present, washing process is prohibited in Guangxi, and only drying, scattering and screening processes can be adopted after the washing process is prohibited, so that new dust pollution, coal pollution and high desliming processing cost are brought.

After years of mining, the laterite type bauxite begins to be depleted and needs to be deslimed, but the two processes are difficult to meet the requirements of a large amount of bauxite processing production.

The development is at the equipment of mine desliming, separates ore and earth on the spot in the mine, can directly return earth ploughing, reduces the influence to the environment to minimum, simultaneously can greatly reduced desliming processing cost, to reducing desliming cost, environmental protection have the significance.

Applicant filed patent 2020113714452 on 30/11/2020, the clay-containing cake waterless deslimer; the applicant reported patent 2021100948199, patent 5631, patent anti-blocking block anhydrous desliming machine, both patents can separate ore and soil on the spot in mine, but can better turn over material in the desliming process, which further improves the desliming effect.
