The utility model is more beneficial to the decomposition of coal slime blocks through baffle and nozzle washing, stabilizes the quality of recovered clean coal and improves the recovery rate of clean coal.
Description
Technical Field
The utility model relates to a coal slime block decomposition device for washed tailing coal.
Background
The raw coal crusher is a main device for crushing coal briquettes in a coal washery, the crushing mode is a tooth roller type crusher, coal slime blocks with the crushing granularity of less than or equal to 50mm cannot be fully decomposed after entering a washing system, undecomposed coal slime blocks are mixed with clean coal, ash content of the clean coal is unstable, and the recovery rate of the clean coal is reduced.
And (3) searching documents: [ authors ]: liu Yuan Wang, Guo Jing, [ Unit ]: coal slime reclassification company of Huoyantong investment Limited company of Huzhou coal and electricity group; [ title ] of: design and practice of multi-stage flotation process of fine-grained tail coal slime [ key words ]: tail coal ash resource utilization efficiency of fine coal slime flotation process and clean coal recovery rate waste discharge by combustible body recovery rate technology.
According to the above-mentioned document search, it is found that, in the domestic situation, at present, 50mm coal slime blocks cannot be sufficiently decomposed after entering a washing system, and the undecomposed coal slime blocks are mixed with clean coal.
Disclosure of Invention
The utility model aims to provide a device for decomposing coal slime blocks of tailings entering washing, which is more beneficial to the decomposition of the coal slime blocks, stabilizes the quality of recovered clean coal and improves the recovery rate of the clean coal.
The utility model adopts the technical scheme that the coal slime block decomposition device for the coal slime entering the washed tail coal comprises a spray pipe and a sieve plate which are arranged on a linear vibrating screen, wherein the lower end of the spray pipe is horizontally provided with a horizontal spray pipe, the pipe wall of the front side of the horizontal spray pipe is horizontally and uniformly provided with a plurality of high-pressure spray nozzles at intervals, the sieve plate is positioned below the spray nozzles, a baffle plate is vertically and fixedly arranged on the surface of the sieve plate in front of the spray nozzles, and the length of the baffle plate is the same as the width of the vibrating screen.
The baffle is made of manganese steel screen mesh, and the height between the center line of the water nozzle and the sieve plate is matched with the height of the baffle.
The horizontal distance between the baffle and the water spray nozzle is 150 mm.
The number of the nozzles is 14.
The length of the baffle is 3600 mm.
According to the utility model, two clean coal linear sieves are replaced by the sieve plates which are customized and provided with the baffles, the coal slime blocks which are separated by the non-pressure feeding cyclone and are not decomposed enter the clean coal linear sieves, the baffles block the coal slime blocks, and meanwhile, the coal slime can be washed down and thoroughly sieved to a qualified medium barrel by additionally arranging a water spraying structure, the separation is carried out by the heavy medium of the coal slime, the clean coal ash content is stabilized, and the recovery rate of clean coal is improved. The utility model has reasonable structure, better use effect, easy modification and favorable popularization.
Drawings
The present invention will be described in further detail below with reference to the accompanying drawings.
FIG. 1 is a schematic front view of the present invention;
fig. 2 is a schematic top view of the present invention.
Detailed Description
The utility model provides an go into and wash tail coal slime piece decomposition device, as shown in figure 1, 2, include spray pipe 3, the sieve 6 that is setting up on rectilinear vibrating screen 2, 3 lower extreme levels of spray pipe set up the water spray and violently manage, the front side pipe wall that the water spray was violently managed is improved level and is being set up a plurality of high pressure water spout 4 at the even interval, sieve 6 be located 4 below the water spout, vertical fixed baffle 5 that is setting up on 6 faces of sieve in 4 the place ahead of water spout, the length of baffle 5 with 2 width of vibrating screen the same.
The baffle 5 is a baffle composed of a manganese steel screen, has high structural strength and can bear larger impact. The height between the central line of the water nozzle 4 and the sieve plate 6 is matched with the height of the baffle 5.
The horizontal distance between the baffle 5 and the water spray nozzle 4 is 150 mm.
The number of the water nozzles 4 is 14. The spray pipe 3 is communicated with a high-pressure water source to provide high-pressure water flow for the spray nozzle 4.
The length of the baffle is 3600mm, and the height of the baffle is 160 mm.
When clean coal enters the linear vibrating screen 2 through the arc screen 1, the blocky clean coal is sprayed by the high-pressure water nozzle 4 under certain pressure in the baffle 5 to pass through a scattering sieve and enter a coal slime dense medium system for separation. After the method is implemented, the coal slime blocks are completely decomposed under the action of the baffle 5 and the water spray nozzles 4 and enter the coal slime dense medium separation, so that the quality of recovered clean coal is stabilized, the recovery rate of the clean coal is improved, and the recovery rate of the clean coal is improved from 50% to 60%.
