Specific implementation mode
The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1 and Figure 2, the embodiment of the present invention is used for converter dry dust pelletizing system, and in order to simplify attached drawing, Fig. 1, Fig. 2 are only
Show that devaporizer 1, the rubber curved 2 of converter dry dust pelletizing system, rubber curved 2 can also be referred to as curved rubber hose, middle part
Downwardly projecting, one end is connect with the outlet of devaporizer 1.It should be noted that the present embodiment both can be manufactured completely newly, also may be used
To be transformed to traditional converter dry dust pelletizing system, to form the structure of the present embodiment, its advantage is realized.
As shown, the embodiment of the present invention includes：Ash bucket 6, urgent ash releasing tube 91, urgent gate valve 8, double turns over ash releasing tube 9
Plate valve 10, expansion joint 11, manhole 5, nitrogen tube 12, nitrogen valve 13.
Specifically, ash bucket 6 is the tubular structure that upper end is more than lower end, appearance is similar to frustum shape, funnel in other words
Shape, the upper end port are connected with positioned at curved 2 bottom of rubber of 1 lower section of devaporizer, to receive the discharge of devaporizer 1
Cinder.The upper end of ash releasing tube 9 is connected to the lower end port of ash bucket 6, and lower end and a cinder storehouse 14 connection, ash releasing tube 9 are discharged thick
Ash is temporarily stored into cinder storehouse 14, waits for the transports such as truck.Double flap valves 10, urgent gate valve 8 are respectively arranged on ash releasing tube 9 and tight
On anxious ash releasing tube 91, ash releasing tube 9, urgent ash releasing tube 91 upper end be all connected to ash bucket 6, lower end is all connected to cinder storehouse 14, and
The two is vertically arranged up and down, is then that left and right is arranged in parallel therebetween, double flap valves 10 form main ash discharge system with ash releasing tube 9
System, urgent gate valve 8 form urgent dust removing system with urgent ash releasing tube 91.Urgent gate valve 8 is preferably DN600 gate valves, double
Flap valve 10 is preferably 500x500mm pneumatically double flap valves.
Double flap valves 10 are main ash exhauster, are composed in series up and down by two flat valves, i.e., first under by turning over plate valve
Flap valve forms, and pushes valve body to shut and open by cylinder.It is turned over under by the plate valve that turns over of about 10 sequence of double flap valves
The rhythmical alternating movement of one pass valve of a valve opening, the continuous flow regime of dust is cut into sectional among plate valve
It is then fed into following cinder storehouse 14.
When carrying out the work of ash discharge, the plate valve that turns over of double flap valves 10 is first opened, and lower turnover panel valve is closed, and cinder is fallen
Enter and turning between plate valve and lower turnover panel valve, be then shut off and turn over plate valve, open lower turnover panel valve, cinder drops into cinder storehouse 14
It is interior, cinder can constantly be discharged repeatedly；
When maintenance, double flap valves 10 are closed, cinder is isolated in cinder storehouse 14, it can be to double flap valves 10 and cinder
Storehouse 14 carries out service work.When double flap valve failure cisco unity malfunctions, in the case of having 1 ton of ash in cinder storehouse 14, beat
It opens urgent gate valve 8 and ash discharge is carried out by urgent ash releasing tube 91.Urgent gate valve 8 is closed after double flap valves 10 are normal.
Expansion joint 11 is located at 9 lower end of ash releasing tube and 14 connecting portion of cinder storehouse, with slowing down vibration etc..Manhole 5 is located at ash
The side of bucket 6, preferably hinge type manhole.Nitrogen tube 12 uses nitrogen for conveying purging ash bucket 6.Nitrogen valve 13 is set to nitrogen tube
On 12, to control air-flow break-make.Nitrogen tube 12 purges access point 7 by nitrogen and accesses inside ash bucket 6, to stretch into inside ash bucket 6,
Purge the inner wall of ash bucket 6.
In the present embodiment, considers that dust humidity and oxygen are gathered, design nitrogen valve 13 and nitrogen tube 12,13 model of nitrogen valve
Preferably DN50, in application, it is each primary per stove steel purging 6 four walls of inside of ash bucket, prevent four wall dust stratifications inside ash bucket.Have when deashing
Water enters cinder storehouse 14, and the present embodiment can also install deashing ash guiding pipe in 6 side of ash bucket and deashing gate valve is a set of, leads ash
Pipe is led under converter platform, and deashing gate valve is opened when maintenance, is closed cinder storehouse gate valve, is caught using a vehicle, use high pressure
Rifle deashing.
Preferably, ash bucket 6 is in quadrangular shape, including four inclined side walls, and the angle of lateral surface and horizontal plane is 65
~70 degree.
In order to avoid cinder gathers, the present embodiment further includes vibrator 4, is set on the outer wall of ash bucket 6.Preferably, in ash
The respectively installation one of at least both sides of bucket 6, shakes twice ash bucket 6 per stove steel.
The present embodiment further includes breaker 3, is set to the junction of 6 upper end port of ash bucket and rubber curved 2, on broken
The dust stratification block just fallen.In application, when big dust stratification lump is fallen, by the breaker 3, certain parameter can be become less than
Blocky dust stratification, be, for example, less than 150*200*300mm or so bulk ash, so as not to block.
In order to avoid 6 temperature rapid decrease of ash bucket, the present embodiment further includes insulating layer (not shown), is coated on ash
On the outer wall of bucket 6.6 outer wall of ash bucket of the considerations of for structural strength and avoiding dust stratification, the present embodiment is additionally provided with stiffener plate (not
Show), at each side angle of cut of inner wall be arc.Specifically, if the size of ash bucket 6 is about 1000 × 4500 × 5600 (height)
Mm, 12 millimeters of thickness then can set stiffener plate outside ash bucket 6 every 600 millimeters.Add arc at each side wall angle of cut of ash bucket inner wall
The weld seam of shape plate, arc panel and side wall ensures Glabrous thorn, it is ensured that junction not dust stratification.
In addition, curved 2 internal vertical of rubber is equipped with movable spoiler (not shown), the size of movable spoiler in airflow direction
Preferably 1300*1600mm, with prevent flue gas short circuit and because flue gas short circuit generates reentrainment of dust in ash bucket.
If the prior art is transformed using the present embodiment, original chain type cinder conveyer should be removed, cut off devaporizer 1
The defeated grey chain shell in bottom designs one ash bucket 6 of installation in its bottom.Pneumatic double flap valves 10 may be used original program control and
Electric control structure.6 four sides of ash bucket each new upper 0.55KW electric motor of shaker at 14.5-15.5 meters of absolute altitude, north and south two sides
Two remote controls, using the remote control signal of former bottom chain motor, and by the control modification of program of former bottom chain motor, if
Set remote manual, automatic function pattern.The electrical control (maintenance and auxiliary rapping use) on the spot of two electric motor of shaker scenes of thing.It is existing
Field installation purging DN50 repid cut-off valves one, 24V power supplys, using the signal control of urgent gate valves above former pair of flap valves
System.
In conclusion the present invention makes the chain type cinder conveyer of devaporizer into inclined plate ash bucket direct ash discharge, cinder is in weight
Ash cellar is entered by ash bucket decline passway under power and centrifugation force effect, completes direct ash discharge function.It is simple in structure, it can meet and turn
The direct ash discharge requirement of stove dry-dedusting system devaporizer, improves converter operating rate, reduces operating cost.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, all things considered are all merely illustrative, not the only.Institute
Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
