Background
Referring to fig. 6, a conventional heavy medium shallow slot coal separator comprises a chain, a scraper, a uniform distribution plate, a vertical inflow port and a horizontal inflow port, and when the feed lump coal is fed into a separation slot, the feed lump coal is fully immersed into suspension under the action of a regulating baffle. The low-density objects such as clean coal float on the upper layer, and the high-density objects such as gangue sink to the bottom of the tank body. In the sinking process, the low-density matters mixed with the gangue continue to float up after being fully dispersed due to the action of upward flow. Under the action of horizontal flow, the low-density material floating on the upper part is discharged from the discharge overflow port to become a clean coal product. Under the action of the scraping plate, the high-density matters sunk to the bottom of the tank are discharged by the machine head chute to become gangue products, thereby completing the sorting process.
In the process that the gangue on the even distribution board is scraped to the scraper blade, the reaction force of gangue acts on the scraper blade, produces crooked power, reduces the end pitch, gives the great side effort of chain, increases the jump chain, blocks the chain, falls phenomenon such as chain, influences normal production, and great side effort also can reduce the life of chain and sprocket simultaneously.
Secondly, the heavy medium suspension is usually added with magnetite powder, and is an unstable fluid which is easy to adhere, deposit and scale, so that the blockage of the uniformly distributed plate holes and the pipelines is a common problem, the blockage of the uniformly distributed plate holes can cause the unsmooth flow of the upflow, the adverse phenomena of reducing the recovery rate, increasing the energy consumption and the like, and the production cost and the unstable product quality are caused.
