At present, some crushing equipment has also appeared for smash the coal sample, but can raise a large amount of coal sample dust and coal ash at crushing in-process, lead to operational environment relatively abominable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a preprocessing device before coal detects to can raise a large amount of coal sample dust and coal ash in the crushing process who exists among the solution prior art, lead to operational environment than poor problem.
In order to achieve the above object, the utility model discloses a preprocessing device is used following technical scheme before coal detects: the utility model provides a preprocessing device before coal detects, includes the casing, and the casing top is provided with the feed inlet, and the casing is inside to be provided with crushing roller in the feed inlet below, and the casing is inside to be provided with the shale shaker in crushing roller below, and the casing is stretched out to the lower extreme of shale shaker, is provided with dust absorbing device on the casing.
A first partition plate is arranged in the shell and divides the interior of the shell into a dust containing cavity and a coal sample crushing cavity, a gap is formed between the upper end of the first partition plate and the top wall of the shell, and a dust inlet for dust to pass through is formed in the gap; a second partition plate is arranged in the dust containing cavity, a gap is formed between the lower end of the second partition plate and the bottom wall of the shell, a filter screen is arranged between the second partition plate and the side wall of the shell, the second partition plate, the top wall of the shell and the filter screen define a first cavity, the first partition plate, the second partition plate, the side wall of the shell, the bottom wall of the shell and the top wall of the shell define a second cavity, and the second cavity is communicated with the coal sample crushing cavity through the dust inlet; the dust absorption device comprises a dust absorption fan which is arranged on the shell and communicated with the first cavity.
The first cavity is internally provided with a flapping structure for flapping the filter screen to clean dust on the filter screen.
The flapping structure comprises a rotating shaft which is rotatably arranged in the first cavity, and flapping rods which are provided with flapping filter screens are arranged on the rotating shaft at intervals along the circumferential direction.
Each beating rod is connected to the rotating shaft through a spring.
And the shell is provided with a cleaning window which is communicated with the second cavity and is used for cleaning dust in the second cavity.
The utility model has the advantages that: coal sample can be raised by a large amount of dust and dust when crushing through the crushing roller and screening through the multistage vibrating screen, and the dust can be absorbed through the dust absorption device, so that the dust and the dust in the surrounding environment can not enter the surrounding environment, the dust and the dust in the surrounding environment are ensured to be as few as possible, and a good working environment is provided for operators.

FIG. 1 is a schematic structural diagram of an embodiment of a pre-treatment device for coal detection according to the present invention;
fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
The utility model discloses an embodiment of preprocessing device before coal detects, as shown in fig. 1-2, including casing 1, casing 1 top is provided with feed inlet 2, and the casing is inside to be provided with a pair of crushing roller 3 below the feed inlet. Inside the casing is provided with shale shaker 4 in crushing roller below, and the shale shaker adopts multistage shale shaker in this embodiment, and the casing is stretched out to the lower extreme of multistage shale shaker, and multistage shale shaker belongs to prior art, no longer details in its concrete structure this embodiment. The shell is provided with a dust absorption device.
The inside first baffle 5 that is provided with of casing, first baffle 5 accomodates chamber 6 and the crushing chamber 7 of coal sample with the inside dust of cutting apart into of casing, has clearance 16 between first baffle upper end and the casing roof, and the clearance forms the dust import that supplies the dust to pass through. A second partition plate 8 is arranged in the dust storage cavity, a gap is formed between the lower end of the second partition plate and the bottom wall of the shell, and a filter screen 17 is arranged between the second partition plate and the side wall of the shell. The side wall of the shell, the second clapboard, the top wall of the shell and the filter screen form a first cavity 9. First baffle, second baffle, casing lateral wall and casing diapire and casing roof enclose into second cavity 10, and the cavity intercommunication is smashed with the coal sample through above-mentioned dust import to the second cavity. The dust absorption device comprises a dust absorption fan 11 which is arranged on the shell and communicated with the first cavity.
A flapping structure for flapping the filter screen is arranged in the first cavity to clean dust on the filter screen. The flapping structure comprises a rotating shaft 13 rotatably installed in the first cavity, and a driving motor for driving the rotating shaft to rotate is arranged on the shell. Beating rods 14 for beating the filter screen are arranged on the rotating shaft at intervals along the circumferential direction. Each beating rod is connected to the rotating shaft through a spring 15, and the beating rod is a rubber rod in the embodiment. The shell is provided with a cleaning window 12 which is communicated with the second cavity and used for cleaning dust in the second cavity.
When using, when the coal sample smashes through crushing roller and when screening through multistage shale shaker, have a large amount of dusts and dust and be raised, under the effect of dust absorption fan, dust and dust get into the dust through the dust import and accomodate the chamber, through the filter screen, clean air is taken away, and dust are left to carry out periodic cleaning through the clearance window.
In other embodiments of the utility model, the multistage vibrating screen can be replaced by a common single-stage vibrating screen; each flapping rod can also be connected to the rotating shaft through a rope.
