Description
Technical field
The utility model belongs to coal separation technical field, more particularly, to using discharge refuse on a kind of air dry sand Recognition Applied in Coal Preparation System
Negative pressure system in system.
Background technique
The main purpose of raw coal separation is to separate cleaned coal with spoil, divide, to obtain clean cleaned coal resource, currently,
Leading technology is wet coal preparation in the art, and because of the variety of problems drawback of wet coal preparation, the present inventor is developed without water
Air dry sand coal preparation technology atmosphere is fluidized using air and dry sand media implementation, according to essence in air dry sand coal preparation technology
The density difference realization of coal and spoil separates, wherein discharge refuse be influence integrated air dry sand cleaning unit can work normally, energy
One of an important factor for no realization industrial applications.
Discharge refuse in dry coal preparation on chain mainly by fixing scraper plate, and chain is driven by driving wheel, due to
Dry coal preparation can allow coal and spoil to be layered, therefore spoil can be located at lower layer since density is bigger, pass through chain lower layer in this way
Scraper plate can release spoil；This structure when in use can be by size spoil and the unified discharge of medium, but chain is easy to stick into
Spoil, this damage to chain are larger；Although there are also will be collected again after spoil size separation, due to small
It is contained a large amount of impurities in grain spoil and medium, this mixes medium in later separation Shi Huiyu impurity, to influence subsequent two
Secondary use；It is therefore desirable to be improved.
Utility model content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of air dry sand Recognition Applied in Coal Preparation System
On with the negative pressure system on waste stone exhaust system, it is hardly damaged equipment and can remove the spy of impurity in medium when having screening spoil
Point.
To achieve the goals above, the technical scheme adopted by the utility model is on a kind of air dry sand Recognition Applied in Coal Preparation System
With the negative pressure system on waste stone exhaust system comprising negative pressure chamber, exhaust fan, media filtration sieve, surge chamber, suction blower, the first valve
Door, the second valve and discharge pipe, the discharge pipe are located in surge chamber；First valve is located at the charging of discharge pipe
On mouth, second valve is located on the discharge port of discharge pipe；The suction blower be located at the first valve and the second valve it
Between, and it is connected to discharge pipe；The discharge pipe is connected to negative pressure chamber；The upper side of the negative pressure chamber is provided with exhausting
Mouthful, the exhaust fan is connect with suction opening, and the exhaust fan rear portion is connected with dust settling pocket；The media filtration sieve is arranged in exhausting
On mouth；The bottom of the negative pressure chamber is provided with feed opening.
The exhaust fan is roots blower.
First valve and the second valve are Unidirectional solenoid valve.
The position of the suction opening is higher than the position of discharge port.
After adopting the above structure, the utility model is compared to the prior art advantageously: the utility model makes
It is not easy to damage equipment in, the staggeredly use of the first valve and the second valve can allow the pull of vacuum of negative pressure chamber to keep
Stablize；Media filtration sieve can also prevent medium from being sucked by exhaust fan while removing impurity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
It encloses, the present invention will be further described with reference to the accompanying drawings and examples.
Embodiment, as shown in Figure 1: with the negative pressure system on waste stone exhaust system on a kind of air dry sand Recognition Applied in Coal Preparation System comprising
Negative pressure chamber 10, exhaust fan 11, media filtration sieve 12, surge chamber 13, suction blower 14, the first valve 15, the second valve 16 and go out
Pipe material 17,17 both ends communicating structures of discharge pipe are located in surge chamber, and the separation chamber on one end and waste stone exhaust system
Connection, the other end are connected to negative pressure chamber 10, and the little particle spoil and medium that such separation chamber is discharged can pass through discharge nozzle
Road 17 is discharged into negative pressure chamber 10.First valve 15 and the second valve 16 are Unidirectional solenoid valve, and the first valve 15 is located at discharge nozzle
On the feed inlet in road 17, the second valve 16 is located on the discharge port of discharge pipe 17, suction blower 14 be located at the first valve 15 with
Between second valve 16, and it is connected to discharge pipe 17；When suction blower 14 works, the first valve 15 is opened, the second valve
Door 16 is closed, and under the action of suction blower 14, suction pipeline 17 can inhale the little particle spoil and medium of separation chamber bottom
It is attached to inside it.The upper side of negative pressure chamber 10 is provided with suction opening, and the position of suction opening is higher than the position of discharge port, exhaust fan 11
It for roots blower, and is connect with suction opening, is connected with dust settling pocket at exhaust fan rear portion, media filtration sieve 12 is arranged in suction opening
On, since medium is generally iron ores particle, so the generally magnetic filtering sieve of media filtration sieve 12；When exhaust fan 11 works,
First valve 15 closure, the second valve 16 is opened, at this point, the spoil and medium of suction pipeline 17 can be inhaled into negative pressure chamber 10
It is interior, it is collected due to spoil and its heavier bottom that can fall to negative pressure chamber 10 of medium specific gravity, and by feed opening；And dust etc. is miscellaneous
Matter can be sucked by exhaust fan 11 and be collected by dust settling pocket, meanwhile, little particle medium is sucked by exhaust fan 11 in order to prevent, medium mistake
Screen can be collected from feed opening again after the drops by media isolation in negative pressure chamber.
