Description
Technical field
The present invention relates to a kind of coal sample reduction device.
Background technology
In process of preparing coal sample, sample is needed by broken, division, mixing and drying and other steps, and being prepared into being capable of generation
The sample for analysis of table original sample characteristic.Sample it is broken it is main by disintegrating apparatus (such as hammer mill) by bulky grain
Sample by extruding, hit, the operation such as cutting is made analysis sample.
Common disintegrating machine is generally that one-level is crushed, and there is broken uneven, broken insufficient phenomenon unavoidably, has influence on coal
The accuracy of matter chemical examination.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of coal sample reduction device, the device can be to coal
Sample carries out two-stage and crushed, and crushes uniformly, fully, improves the accuracy of coal qualities test.
To achieve these goals, the present invention provides a kind of coal sample reduction device, including charging aperture, and the bottom of charging aperture connects
Broken case I is met, described broken case I inner spaces are divided into top as boundary using the screen cloth I being disposed therein and crush space and bottom
Splicing space, described top crushes the breaker roll I rotated in opposite directions provided with a pair in space, and described bottom splicing space is one
Cavity, is provided with discharging opening I in the bottom of cavity, sets vibrating motor I on described screen cloth I lower surface, crushes case I and screen cloth
Breach is provided with the side of I horizontal position, described breach is connected by pipeline I with broken case II, described broken case
II inner spaces are divided into top as boundary using the screen cloth II being disposed therein and crush space and bottom splicing space, and described top is broken
Provided with the breaker roll II rotated in opposite directions for a pair in broken space, described bottom splicing space is a cavity, is opened in the bottom of cavity
Provided with discharging opening II, vibrating motor II is set on described screen cloth II lower surface, case II and screen cloth II horizontal level is crushed
Breach is provided with the side at place, described breach is connected by pipeline II with pulp-collecting box.
Further, mutually parallel registration is set two pairs of described breaker rolls in its broken case.
In the technical scheme, by setting two-stage crushing system in the lower section of charging aperture, coal sample enters one from charging aperture
In the broken case of level, under the squeezing action of breaker roll, coal cinder is crushed, and the coal dust for meeting crushing sieve mesh requirement is fallen into by screen cloth
Bottom splicing space, is collected from discharge outlet, and as the raw material of analysis of coal sample, the coal cinder for not meeting sieve mesh requirement is temporarily isolating
On screen cloth, and moved under the effect of vibration of vibrating motor to screen cloth side, eventually through broken case and the horizontal level of screen cloth
The breach opened up on the side at place falls into pipeline, into two-stage crushing case, under the squeezing action of breaker roll, coal cinder again by
Crush, the coal dust for meeting crushing sieve mesh requirement falls into bottom splicing space by screen cloth, is collected from discharge outlet, is used as coal sample point
The raw material of analysis, the coal cinder for still not meeting sieve mesh requirement is temporarily separated on screen cloth, and the effect of vibration through vibrating motor is to sieve
Net side side is moved, and the breach opened up on the side eventually through broken case and the horizontal position of screen cloth is fallen into material collecting box, no
As the raw material of analysis of coal sample, such two-stage is crushed, and be ensure that the uniform abundant of coal sample reduction, is prevented from not meeting coal sample
The coal cinder of size requirements is mixed into wherein, improves the accuracy of analysis of coal sample.
Further, according to needed for analysis of coal sample feed particles size, two pairs of breaker rolls in its broken case mutually
Parallel registration is set.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of coal sample reduction device, including charging aperture 1, the broken case I13 of bottom connection of charging aperture 1, institute
The broken case I13 inner spaces stated are divided into top as boundary using the screen cloth I14 being disposed therein and crush space and bottom splicing space,
Described top crushes the breaker roll I2 rotated in opposite directions provided with a pair in space, and described bottom splicing space is a cavity,
The bottom of cavity is provided with discharging opening I12, sets vibrating motor I3 on described screen cloth I14 lower surface, crushes case I13 and screen cloth
Breach is provided with the side of I14 horizontal position, described breach is connected by pipeline I4 with broken case II5, described is broken
Broken case II5 inner spaces are divided into top as boundary using the screen cloth II11 being disposed therein and crush space and bottom splicing space, described
Top crush provided with the breaker roll II6 rotated in opposite directions for a pair in space, described bottom splicing space is a cavity, in cavity
Bottom offer discharging opening II9, vibrating motor II10 is set on described screen cloth II11 lower surface, case II5 and sieve is crushed
Breach is provided with the side for the horizontal position for netting II11, described breach is connected by pipeline II7 with pulp-collecting box 8.
The size of feed particles according to needed for analysis of coal sample, mutually parallel registration is set two pairs of breaker rolls in its broken case
