Description
Technical field
The present invention relates to machinery equipment field more particularly to a kind of novel center feeders.
Background technique
The run coal bin of unit pulverized-coal system configuration is used in large-size thermal power plant, it is miscellaneous since the place of production of material is different
Matter content is different, and viscosity is also different, during material flows downward in warehouse, due to the cross sectional dimensions of taper warehouse
It reduces, the extruding force by bulkhead is increasing, and original loose particle is extruded reunion, clustering phenomena occurs, works as conglomeration
Characteristic size reach certain critical value, blocking is easy for occurring.And blocking when coal charge occurs and declines in storehouse, power generation
The boiler combustion shakiness that unit just will appear causes largely throwing oily combustion-supporting, can waste great amount of fuel oil, the more serious boiler that will lead to goes out
Fire, unit unplanned outage.Currently, center feeder is a kind of equipment for the output of feed bin material dosing, for solving
Blockage problem is stated, but existing center feeder, during actual operation, rotary scraping arm is in rotary motion in feed opening
Place is still easy to appear the phenomenon that fine coal accumulation, causes blanking unstable, in addition can not blanking the phenomenon that.
Summary of the invention
For the prior art there are problem, the present invention proposes a kind of novel center feeder, material can be prevented in blanking
Packing phenomenon at mouthful, it is ensured that blanking is steady.
To achieve the above object, the present invention proposes a kind of novel center feeder, including feed bin ontology, support arm, water conservancy diversion
Cone, blanking table and rotary scraping arm；It further include the blowing device that deflection cone lower part is set；The blowing device includes air pressure
Contracting tank, blowing supervisor, blowing branch pipe and nozzle；Described air compression tank one end is connect with external air source, and the other end and blowing are led
Pipe connection；The blowing branch pipe is equipped with the lower edge in deflection cone, and whole annular in shape around deflection cone bottom
Edge setting, blowing branch pipe and blowing supervisor are cooperatively connected；Nozzle is provided on the blowing branch pipe.
The lower section of support arm is arranged in the blowing supervisor, and is obliquely installed.
The blowing branch pipe is mounted on deflection cone lower edge, and the diameter for being blown the annulus that branch pipe is formed is less than water conservancy diversion
Bore the diameter of lower edge.
Uniform intervals are provided with nozzle on the blowing branch pipe.
Beneficial effect
The present invention is blown compressed air downwards compressed air by multiple nozzles by the blowing device of setting, thus
Coal dust edge at the feed opening below deflection cone is avoided to form accumulation.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present invention proposes a kind of novel center feeder, including feed bin ontology 1, support arm 2, deflection cone 9, blanking table
3 and rotary scraping arm 8；It further include the blowing device that 9 lower part of deflection cone is set；The blowing device include air compression tank 5,
Blowing supervisor 4, blowing branch pipe 6 and nozzle 10；Described 5 one end of air compression tank is connect with external air source, and the other end and blowing are led
Pipe 4 connects；The blowing branch pipe 6 is equipped with the lower edge in deflection cone 9, and whole annular in shape around deflection cone 9
Bottom margin setting, blowing branch pipe 6 and blowing supervisor 4 are cooperatively connected；Nozzle 10 is provided on the blowing branch pipe 4.
The lower section of support arm 2 is arranged in the blowing supervisor 4, and is obliquely installed.
The blowing branch pipe 6 is mounted on 9 lower edge of deflection cone, and the diameter for being blown the annulus that branch pipe 6 is formed is less than
The diameter of 9 lower edge of deflection cone.
Uniform intervals are provided with nozzle 10 on the blowing branch pipe 6.
The pivoting support 7 that rotary scraping arm 8 passes through makes rotating motion, and pivoting support 7 with external impetus equipment by cooperating
Connection；Blowing supervisor 4 and blowing branch pipe 6 are metal circular tube, and air compression tank 5 is connect by the prior art with external air source,
The end of nozzle 10 can be equipped with baffle by the prior art, and baffle is opened outward under the action of compressed air, make to press
The blowout of contracting air.The shape of the blowing mouth of nozzle 10 can be oblateness, be more convenient for for compressed air being blown to side foreign side；It avoids
Feed opening outer edge of the coal dust below deflection cone 9 forms accumulation.It is blown the circle diameter that branch pipe 6 is formed and is less than 9 bottom of deflection cone
The diameter at portion edge avoids blowing branch pipe 6 from stopping the whereabouts of coal dust.Blowing branch pipe 6 can be welded on by metallic connexion frame leads
Flow cone lower part.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
