Description
Technical field
The utility model relates to be added in technical field of coal mine equipment, in particular to a kind of air dry sand Recognition Applied in Coal Preparation System with air
Thermal.
Background technique
The industrial applied research of China's air dry sand coal separation at present and development are more early, but there is presently no realize industry
Metaplasia produces, and does not solve there are also some engineering technology problems, and in air dry sand coal preparation technology, central principle is to utilize medium
And the separation of coal and spoil is realized according to the difference of coal and spoil specific gravity, by be filled in the medium compressed air appropriate by its
Become fluid form, the quality of medium fluid form directly determines the effect that coal is separated with spoil, but is specifically implementing
In operation, medium is easy to appear the fluid effect difference or even can not form fluid form, main cause that caking phenomenon results in
It is that water content in medium is relatively high, the higher fluid form effect that it is formed of water content is poorer in medium, and water content is opposite
Medium will be unable to form fluid form when excessively high, and the moisture source in medium is broadly divided into Wai Shui and interior water, and outer water is mainly mixed
The moisture of surface of material attachment is closed, interior water is the contained moisture of medium itself, and the bad reason of medium fluid form effect determines
Afterwards, it is badly in need of solving this technical problem.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, and providing one kind can be effectively reduced sorting
Air heating apparatus is used on the air dry sand Recognition Applied in Coal Preparation System of indoor moisture content.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: on a kind of air dry sand Recognition Applied in Coal Preparation System
With air heating apparatus, including air chamber, air delivery device and separation chamber, the air chamber is connected to separation chamber bottom, air chamber
On integrally formed with air inlet, air inlet is connected to air delivery device, and the heater for heating inlet charge is equipped in air chamber
Structure.
The utility model compared with prior art the advantages of be: heated and filled with air on a kind of air dry sand Recognition Applied in Coal Preparation System
Setting includes air chamber, heating mechanism, air delivery device etc., and wherein compressed gas is transported to air chamber, compressed gas by air delivery device
Body is heated in air chamber by heating mechanism, and it is stream that the compressed gas after heating, which enters separation chamber for coal separation change of medium,
Body form, structure are simply easily installed and safeguard, by heating after compressed gas can be to the mixing in medium and medium
Material is dried, and the water content in medium is effectively reduced, and avoids medium that from can not being converted to fluid form or be transformed into fluid
Occur caking phenomenon after form, greatly improve the fluid effect of medium, save largely generated because solving the problems, such as this at
This, in coal cinder after sub-electing in separation chamber, water content is greatly reduced, and reduces the work of subsequent coal cinder dehydration
Amount promotes the working efficiency of air dry sand coal separation entirety, and due to sorting indoor heating effect, the air after heating can be full of whole
Cover air dry sand coal picker so that a whole set of air dry sand coal separation built-in temperature is promoted, ensure that complete equipment temperature compared with
Under low environment can normal boot-strap, efficiently solve air dry sand coal picker in extremely frigid zones or compared with cold season section need to carry out pre-
The problem of heat could be switched on, greatly improves coal separation efficiency, saves the preheating cost of air dry sand coal picker, and a kind of air is dry
Air heating apparatus overall structure is used simply on sand Recognition Applied in Coal Preparation System and cost is relatively low, is completely solved because moisture content height is led in medium
The problem of medium fluid effect difference of cause even can not form fluid, ensure that the working efficiency of coal cinder sorting, it is de- to save coal cinder
The cost of water effectively pushes the overall work process of air dry sand cleaning unit.
As an improvement, the heating mechanism includes heating net, heating net is fixed in air chamber with air inlet phase nearby,
Heating net wire side is vertical with airintake direction, and heating net directly all heats air inlet at air inlet, and heating efficiency is high, adds
Heat supply network is made of several heater strips with grid-like distribution, guarantees the homogeneous heating of air inlet.
As an improvement, the heating net is concaveconvex structure, heating net concave surface is opposite with inlet charge direction, bumps knot
Structure greatly promotes the heating efficiency of air inlet, guarantees the compressed gas even heat for entering medium.
As an improvement, the air delivery device includes roots blower and the appendix that is connected to roots blower, appendix
It is connected to air inlet, roots blower performance is good and long service life, guarantees the stable operation of coal cinder sorting work.
