Specific embodiment of the utility model is described in detail below with reference to attached drawing.
It returns mine dredger in order to illustrate blast furnace cloth bag pneumatic ash conveying pipe provided by the utility model, Fig. 1 shows root
It returns mine dredger structure according to the blast furnace cloth bag pneumatic ash conveying pipe of the utility model embodiment.
The dredger as shown in Figure 1, blast furnace cloth bag pneumatic ash conveying pipe provided by the utility model is returned mine, including：It returns mine
Storehouse 7, the collection hopper 1 being arranged on above storehouse 7 of returning mine, the valve 2 being arranged on collection hopper 1, the both ends respectively with storehouse 7 of returning mine are connected
The ash conveying pipe 5 and power source device 3 connect.
Wherein, it returns mine storehouse 7, for placing BF return fines particle 4；Collection hopper 1, for BF return fines particle 4 to be delivered to
It returns mine 7 in storehouse；Valve 2, for controlling collection hopper 1；Power source device 3, for providing power for the dredging of ash conveying pipe 5.
Specifically, in the utility model embodiment, collection hopper 1 is made by the steel plate of 6mm thickness, and collection hopper 1 wraps
Include upper and lower part, upper diameter is Ф 400mm, and lower diameter is Ф 100mm, and the height of collection hopper is 500mm, and weld seam
Inside and outside full weld is not allowed have sand holes.
Power source device 3 includes low-pressure nitrogen, and low-pressure nitrogen drives BF return fines particle 4 to carry out 5 inside of ash conveying pipe
It washes away.
In addition, blast furnace cloth bag pneumatic ash conveying pipe is returned mine, dredger further includes injection tank, and injection tank is arranged on ash pipeline
The position that road 5 is connected with storehouse 7 of returning mine, also, injection tank is connect by connector with ash conveying pipe 5.Wherein, injection tank includes
Material spray, material spray are delivered to by power source device 3 in ash conveying pipe 5.
In the embodiment of the utility model, the principle for dredging ash conveying pipe is：Derusting by sandblasting is to be using compressed air
Material spray is ejected into workpiece surface to be treated by power at a high speed to form high velocity spray beam.The utility model is according to this principle
Low-pressure nitrogen is improved to as power source, BF return fines are that medium is that ash conveying pipe continues to wash away.
Wherein, derusting by sandblasting medium：Sand used in derusting by sandblasting principle, it is desirable that particle is hard, has corner angle, drying, without mud
Soil and other impurities, granularity is in 1.5~2mm or so.But the grains of sand of the grain size carry out screening processing or are specially purchased,
Cost is higher.In view of existing actual conditions, it is to increase existing staff labor intensity manually to carry out screening one, second is that screening effect is not
It is fine.
To solve the above problems, the utility model uses the BF return fines (granularity 3mm or so) after the screening of blast furnace elevator,
And specially sieve or purchase without carrying out, and return mine particle or dedusting ash all can as sinter raw material it is sharp again
With, it may be said that zero cost, therefore that BF return fines is used to be used as material spray is the most suitable for the utility model.
Derusting by sandblasting power：Derusting by sandblasting principle, be by the use of compressed air as power source, and this time engineering design, then
Pipe laying again is needed, it, can be also easily hardened to ash conveying pipe burn into sack dust on the other hand due to containing moisture inside compressed air
Deng adverse effect, therefore original low-pressure nitrogen (about 0.5Mpa) is tried out as power source；By test of many times, nitrogen drive is returned mine
Particle washes away ash conveying pipe inside, reaches and removes the substance of ash conveying pipe inner wall knot thick-layer 6, expands internal diameter of the pipeline, dredges
The effect threaded a pipe.
During injection, material spray, which can be disposably put into, is arranged on the returning mine in storehouse of pipeline initiating terminal, when dredging ash pipeline
Suitable particle of returning mine is put into during road in storehouse of returning mine, closes storehouse of returning mine, pipeline can be washed away by being passed through low-pressure nitrogen, can
Pipeline is repeatedly washed away according to injection effect.
Furthermore, it is necessary to explanation, may also set up special injection tank, (ash conveying pipe 5 is with returning in ash conveying pipe initiating terminal
The position that ore storage bin 7 is connected) connector is set to be connected with injection tank, it is using gas that the material spray fluidisation in injection tank is defeated when dredging
It send to ash conveying pipe, while or opening ash conveying pipe low-pressure nitrogen, recycling nitrogen convey the material spray of penetrating in advance
It washes away, until qualified.
According to above device, the blast furnace cloth bag pneumatic ash conveying pipe of the utility model dredging principle of returning mine is as follows, using stove
Cloth bag pneumatic ash conveying pipe dredger of returning mine dredges ash conveying pipe, and concrete principle is as follows：
1st, BF return fines particle is delivered in storehouse of returning mine by collection hopper；
2nd, when required BF return fines particle is all delivered in storehouse of returning mine, the valve on rotary material collecting bucket, cut-out is received
Expect not connect with outside the connection between the storehouse of returning mine, the storehouse that makes to return mine；
3rd, the low-pressure nitrogen in power source device blows into the BF return fines particle in storehouse of returning mine in ash conveying pipe, right
It is washed away inside ash conveying pipe.
Wherein, the position that the storehouse of returning mine is connected being provided with injection tank in ash conveying pipe, injection tank includes material spray,
In, injection tank is connect by connector with ash conveying pipe.
Low-pressure nitrogen in power source device blows the material spray in injection tank to ash conveying pipe, to ash conveying pipe inside
It is washed away, then low-pressure nitrogen is washed away to spraying into the material spray in ash conveying pipe.
The dredging as can be seen that blast furnace cloth bag pneumatic ash conveying pipe provided by the utility model is returned mine by the above embodiment
Device, by adding valve, hopper on ash conveying pipe top, according to the principle of derusting by sandblasting, by BF return fines particle, (3mm is left
It is right) it is put into inside pneumatic ash conveying pipe, particle of returning mine is conveyed using the gas of certain pressure and washes away inner wall of the pipe by dust stratification at a high speed
It removes, so as to solve the problems, such as that stifled ash easily occurs in blast furnace gas cloth bag dedusting pneumatic ash conveying pipe.
Described in an illustrative manner above with reference to attached drawing according to the utility model proposes blast furnace cloth bag pneumatic transporting ash pipe
Road is returned mine dredger.It will be understood by those skilled in the art, however, that the blast furnace cloth bag proposed for above-mentioned the utility model
Pneumatic ash conveying pipe is returned mine dredger, and various improvement can also be made on the basis of the utility model content is not departed from.Cause
This, the scope of protection of the utility model should be determined by the content of appended claims.
