Abstract
The present invention provides little particle low-order coal or the grading plants of oil shale, including being classified case 1, side air inlet 2, bottom air inlet 3, feed inlet 4, material storing box 5, discharge port 6, specific structure is as follows: classification case 1 is cuboid, with there are two the cylindrical discharge ports 6 of cuboid material storing box 5,1 of feed inlet 4,1 of the bottom cylinder air inlet 3, two of side cylinder air inlet 2, two.The present invention can be classified 1mm or less low-order coal or oil shale particle by gas cross-flow, and classification efficiency is high.
Description
Technical field
The present invention relates to little particle low-order coal or the grading plant of oil shale, belong to the fluid classification technique in gradation
Field.
Background technique
Destructive distillation is the main method of low order kerosene shable deep processing and utilization.But little particle low-order coal or oil shale (<
30mm) excessively it is lower than 1mm fine powder due to carrying secretly, so that it is difficult to directly carry out destructive distillation, it is most difficulty in low-quality fossil fuel
The granularity level of reason, has become industry issue.Therefore, it is necessary to carry out pre-classification, the sub-prime step of variable grain grade is realized
Using (1mm or more particle carries out effective destructive distillation；1mm or less little particle separates recycling).But at present to retort process low-order coal or
The fine grain classification of oil shale is mainly using devices such as whirlwind, grain bed, the cloth bags of destructive distillation rear end, still without for before destructive distillation
Effective corollary apparatus of Duan Jinhang pre-selection classification, needs to improve.
Summary of the invention
In order to overcome the shortcomings of background technique, the present invention provides a kind of classification of little particle low-order coal or oil shale dresses
It sets.
The technical scheme adopted by the invention is that: the present invention provides the classification dress of a kind of little particle low-order coal or oil shale
It sets, lower than 30mm little particle low-order coal or oil shale material through two feed pipes vertically into classification case, bottom airflow at this time
It is vertical with crossflow to meet, cross-flow is formed, will realize that 1mm or less fine grained suspends and is laterally blown into side storage bin, be greater than
1mm particle falls into bottom side storage bin, realizes effectively classification.The invention mainly comprises classification case, side, bottom air inlet, into and out of
Material mouth, material storing box etc..
Detailed description of the invention
Fig. 1 is the perspective view according to currently preferred one embodiment.
Appended drawing reference: classification case 1, side air inlet 2, bottom air inlet 3, feed inlet 4, material storing box 5, discharge port 6
Specific embodiment
More preferably to illustrate the present invention, the preferred embodiment of the present invention is described further with reference to the accompanying drawing: such as Fig. 1,
The present invention provides a kind of little particle low-order coal or the grading plant of oil shale, including classification case 1, side air inlet 2, bottom into
Port 3, feed inlet 4, material storing box 5, discharge port 6, the specific structure of the present embodiment are as follows.
Classification case 1 is cuboid.With there are two the bottom cylinder air inlets 3, two of side cylinder air inlet 2, two
The discharge port 6 of cuboid material storing box 5,1 of cylindrical feed inlet 4,1.
When < 30mm material enters classification case 1 by feed inlet 4, bottom air inlet 3 and 2 air-flow of side air inlet cross to be formed
Cross-flow, the gas entered by bottom air inlet 3 will be so that 1mm or less low-order coal or oil shale little particle suspend, by side air inlet
1mm or less little particle is blown into material storing box 5 by the gases that mouth 2 enters, and drops down onto discharge port 6 greater than 1mm bulky grain, is realized and is effectively divided
Grade.
The present invention directly carries out pre-classification to little particle, 1mm or more particle is efficiently used, classification efficiency
It is high, structure is simple, easy for installation and occupied space small volume.
It should be noted that described above is only the demonstration and indicative explaination for the present embodiment, not to this hair
Bright protection scope is defined.Do not depart from the present invention design under the premise of, it is all technical solution of the present invention is made it is each
Kind improvement and deformation, should all fall into the protection scope that claims of the present invention determines.
