Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Referring to Fig. 1; The invention provides a kind of online intercepting high-temperature slag safety shut-off valve device, it mainly is made up of cylinder 1, counterweight 2, chain 3, preset pieces 4, support 1, sprocket wheel assembling 6, water-cooled tube 8, spacing place 9, clack box 10, support 2 11, valve plate 12 and slag runner 13.
Clack box 10 is fixed on above the slag runner 13 through support 2 11, and support 1 is fixed on clack box 10 tops.Cylinder 1, sprocket wheel assembling 6, spacing place 9, preset pieces 4 are fixed on the support 1.Counterweight 2 is connected with cylinder 1, and chain 3 one ends are connected on the counterweight 2, and chain 3 the other ends are connected on the valve plate 12.
The part of water-cooled tube 8 is cast in the valve plate 12,12 fens two-way water coolants of valve plate, one tunnel water quench valve plate, 12 tops wherein, another water quench valve plate 12 bottoms, road.Be provided with the gap between the side of valve plate 12 and the slag runner 13.
The shut off valve device also is equipped with dreg scraper 7, and dreg scraper 7 is fixed on clack box 10 bottoms.Clack box 10 bottoms are provided with refractory materials.Clack box 10 inside are provided with water coolant, and water coolant is opened in tap cinder, after tap cinder finishes, close.
On blast furnace residue channel, place one and get the slag cut-off equipment; At first to consider the blast furnace slag temperature to getting the influence of slag cut-off equipment, if moreover valve means break down, just can cause high-temperature slag to overflow slag ladle; Burn out and embrace a tank car and a peripheral equipment, even staff is on every side damaged.Since can not iron content in the mineral wool manufacturing technique requirent slag, so this device also will be considered the isolating function of slag iron.
Referring to Fig. 2 and Fig. 3, shown among the figure and got the slag link in the mineral wool production technique.Have a mineral wool in blast furnace residue channel 20 sides and get slag runner 22, the slag flow path direction is by diagram A direction.Mineral wool is got slag runner 22 position of slagging tap and is provided with slag ladle 23 and connects slag, and slag ladle 23 transports by embracing a tank car 24.Mineral wool is got between slag runner 22 and the blast furnace residue channel 20 has certain elevation difference, gets under the scoriform condition non-, and the slag flow liquid face in the blast furnace residue channel 20 is lower than the bottom surface absolute altitude that mineral wool is got slag runner 22 all the time.When getting slag cut-off equipment 21 work, the slag flow liquid faces in the blast furnace residue channel 20 rise, and when liquid level was higher than mineral wool and gets the bottom surface absolute altitude of slag runner 22, slag was normally got in beginning.
Shut off valve device of the present invention can be realized online damming and the separation of slag iron, and reaches the purpose of damming safely.
Below in conjunction with Fig. 1,2,3 and following content shut off valve device of the present invention is done further to describe.
Slag temperature in the blast furnace residue channel is about about 1500 ° of C, and has a small amount of molten iron, but the slag in the mineral wool production technique can not iron content, so need slag iron be separated.Getting under the scoriform attitude; Because molten iron density is bigger; Can flow along the slag runner bottom, the valve plate 12 in this device leaves certain interval with slag runner 13 bottoms, so molten iron passes through from the gap; And a large amount of slags can be dammed to mineral wool through damming after reaching the certain liquid height and got in the slag runner 22, thereby also just realizes getting slag and the isolating purpose of slag iron.
Because high-temperature slag has certain viscosity, valve plate 12 sides and slag runner 13 in this device also leave certain interval, and this ties the situation that extremely causes valve plate to mention with regard to having been avoided getting in the slag process valve plate and slag runner.
If in getting the slag process, drive system goes wrong, after the valve position of manual setting SV, counterweight 2 can directly be mentioned valve plate 12.
Valve plate 12 rests in the clack box 10 under off working state.12 fens two-way water coolants of valve plate, wherein one the tunnel cools off valve plate 12 tops, another cooling valve plate 12 bottoms (portion of damming), road.Get at needs under the situation of slag, the top water coolant is opened, and cools off through 8 pairs of valve plate 12 tops of water-cooled tube.Start cylinder 1 then, pull-up counterweight 2 comprises that through chain transmission system sprocket wheel assembling 6, chain 3 make valve plate 12 beginnings move downwards, and when arriving lower limit 9, valve plate 12 puts in place, and cylinder 1 quits work, and realizes the online slag of getting.
Finish in case get slag, cylinder 1 begins to move downward under the driving of counterweight 2, and valve plate 12 begins to rise; Spacing 9 the time in arriving; Counterweight 2 stop motion under the effect of cylinder 1, the bottom water coolant is opened in the valve plate 12, cools off through 8 pairs of valve plate 12 bottoms of water-cooled tube; Under quenched condition, the automatic cracking of the slag that is stained with on the valve plate 12 also separates with valve plate 12.Valve plate is after 12 cooling for some time, and cylinder 1 continues to move downward under the driving of counterweight 2, and valve plate 12 continues to rise.
Valve plate 12 if still there is a small amount of slag on the valve plate 12, will be wiped off by dreg scraper 7 in uphill process.When arriving upper limit 9, counterweight 2 arrives preset piecess 4 positions at this moment, and cylinder 1 quits work, and two path waters are closed in the valve plate 12, and whole valve plate 12 is placed in the clack box 10.Clack box 10 bottoms are provided with refractory materials, and inside is provided with water coolant, and water coolant is opened in tap cinder, after tap cinder finishes, close.
In sum; Online intercepting high-temperature slag safety shut-off valve device of the present invention is used for damming in the mineral wool production technique and gets slag; In getting the slag process, can control the size of getting the quantity of slag, guarantee that slag iron separates, and the long service life of valve plate; When equipment breaks down, also can in time valve plate be mentioned, guarantee that blast furnace residue channel slag stream is smooth and easy.
Certainly; Those skilled in the art in the present technique field will be appreciated that; The foregoing description only is to be used for explaining the present invention; And be not with opposing qualification of the present invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention the variation of the foregoing description, modification etc.
