Description
Technical field
The utility model is related to fine coal conveying technology, more particularly to a kind of fine coal blanking and conveying device air filling cone.
Background technology
Powdered coal pressuring gasified technology is that the clean energy resource developed in recent years utilizes one of technology, compared with coal water slurry gasification,
Its technical characterstic has：Carbon conversion efficiency height, cold gas efficiency height etc..In powdered coal pressuring gasified technique, fine coal conveying belongs to core
One of heart technology, its stability conveyed is most important for gasification furnace stabilization, long-term operation.
Fine coal conveying technology contains gravity blanking technique and pneumatic conveying process, and wherein gravity blanking technique capital equipment is
Coal dust bunker and lock hopper, pneumatic conveying process capital equipment are material issuing tank, and equipment is arranged from top to bottom according to technological process.It is actual
In technique, the fine coal in coal dust bunker enters lock hopper by flow by gravity, through transformation, and fine coal flows into material issuing by gravity again
Tank, then, fine coal enter burner using inert gas as carrier gas, by the mode of Geldart-D particle and carry out gasification reaction.In order to ensure
The stability of conveying, three above key conveying equipment bottom is provided with air filling cone, and its operation principle is to utilize low pressure or height
Body of calming the anger forms uniform gas by air filling cone and impacted, and the fine coal near air filling cone is in even fluidizing state, so that
The course of conveying of fine coal is set more to stablize, conveying effect is more preferable.
Publication number CN201493478U, the Chinese patent literature in publication date on June 2nd, 2010, discloses one kind and uses powder
Sintering metal multi-hole conical prepared by last metallurgical method, the multi-hole conical is fixed on inside taper delivery pipe, is then passed through gas from outside
Body makes gas be uniformly distributed in inside cone, so that solid material fluidised form.The shortcoming of the air filling cone is：It can not bear larger
Interior male cone (strobilus masculinus) pressure difference, excessive pressure difference easily makes its damaged, and ultimately results in air filling cone failure.
Publication number CN201495203U, the Chinese patent literature in publication date on June 2nd, 2010, disclosing one kind can hold
By the air filling cone of more High Pressure Difference, the air filling cone is made using stainless steel material, and taper barrel is provided with through hole to facilitate fluidisation
Gas enters.The shortcoming of the air filling cone is：I.e. excessive passage may cause coal dust to flow on the outside of cone, and then influence normal stream
Change process.
Publication number CN102676233A, publication date in September, 2012 Chinese patent literature of 19 days, discloses a kind of sintered gold
Genus polyporus cone reinforcement structure, the air filling cone in sintering metal internal face covered with reinforcer, to bear higher pressure difference, but its
Have the disadvantage：Reinforcer blocks the inlet channel of large area, fluidized gas may be caused to flow into not smooth.
Publication number CN202625048U, the Chinese patent literature in publication date on December 26th, 2012, discloses a kind of fine coal
The air filling cone of gasification installation, the air filling cone includes conical shell, and the conical shell has at least one be made up of sintering metal
Individual inflation area；And reinforcer, the reinforcer is located on the wall of the conical shell and at least covers the inflation area, institute
State and be formed with reinforcer multiple through holes.But the limited pressure that the air filling cone of the structure can bear.
In summary, Conventional pneumatic is bored or is made of steel plate, is punched on steel plate, but this traditional air filling cone deposits
It is big in aperture, easily occur coal dust and flow backwards, influence the operation of coal dust gasification device；Or be made of sintering metal, but this fill
Gas coning can not bear excessive pressure, and the external and internal pressure that the air filling cone produced at present only up to bear 1.0MPa is poor, and in reality
Often due to pressure difference is excessive or be in the environment of pressure differential to work for a long time and cause air filling cone to be blown brokenly in the production process of border, make
Into stopping production, influence production.
Utility model content
To overcome drawbacks described above, the utility model provides a kind of fine coal blanking and conveying device air filling cone, this inflation
It is fragile that cone not only overcomes similar products（Sintered metal materials）, easily flow backwards（Stainless steel material）, larger pressure difference can not be born
Shortcoming, and solve fine coal blockage problem caused by bridge formation in course of conveying, abrasion can be slowed down, extension product makes
Use the life-span.
The technical solution of the utility model is as follows：
A kind of fine coal blanking and conveying device air filling cone, it is characterised in that：The inflation wall that is made including sintering metal and
The stiffening ring that stainless steel is made；Inflation wall and the stiffening ring wall in a ring, is arranged alternately.
There are some inflation ducts on the inflation wall.
Some row's passages, a diameter of 4 ~ 6mm of passage are uniformly provided with the stiffening ring.
To avoid coal dust from flowing backwards, the passage is set diagonally downward, and between the wall of air filling cone have be tilted towards
Under certain angle.
The cone angle of the air filling cone is 30 °.
Sintering metal inflation wall of the present utility model is main gas inlet passages, and carrier gas is by being evenly distributed, aperture
Trickle duct, in air filling cone inner surface one layer of uniform air film of formation, reduces the friction of pulverized coal particle and cone surface, it is ensured that
The smooth blanking of fine coal and conveying；The stiffening ring of stainless steel is alternately arranged with sintering metal, as support and connection, to solve to burn
The problem of knot metal can not bear larger inside and outside differential pressure when being used alone.
The beneficial effects of the utility model are as follows：
（1）Coal dust arch formation is effectively prevented, reduces and removes bridge number of times, carrier gas consumption is saved, coal dust transfer efficiency is improved；
（2）Effectively prevent that coal dust from flowing backwards phenomenon, simplify operation difficulty；
（3）High mechanical strength, can bear larger unidirectional inside and outside differential pressure, reduce air filling cone damage frequency, long service life；
（4）Be prevented effectively from because delivery of carrier gas it is impure caused by sintering metal filter opening block the problem of.
