Embodiment
Below in conjunction with drawings and Examples 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 comprised 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.
The part of water-cooled tube 8 is cast in the valve plate 12,12 minutes 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 arrange refractory materials.Clack box 10 inside are provided with water coolant, and water coolant is opened in tap cinder, close after tap cinder finishes.
Place one at blast furnace residue channel and get the slag cut-off equipment, at first to consider the blast furnace slag temperature to getting the impact 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 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 function that slag iron separates.
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 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 damming online and slag iron separates, 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 further described.
Slag temperature in the blast furnace residue channel is about about 1500 ° of C, and with a small amount of molten iron, but the slag in the mineral wool production technique can not iron content, so slag iron need to be separated.Getting under the scoriform attitude, because molten iron density is larger, can be along the slag runner flows, 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 by damming after reaching the certain liquid height and got in the slag runner 22, thereby also just realizes getting the purpose that slag and slag iron separate.
Because high-temperature slag has certain viscosity, valve plate 12 sides and slag runner 13 in this device also leave certain interval, and this has just been avoided getting the tied and situation that causes valve plate to mention of valve plate and slag runner in the slag process.
If in getting the slag process, drive system goes wrong, after the valve position of manual setting magnetic valve, counterweight 2 can directly be mentioned valve plate 12.
In case getting slag finishes, cylinder 1 begins to move downward under the driving of counterweight 2, valve plate 12 begins to rise, in arriving spacing 9 the time, counterweight 2 stop motion under the effect of cylinder 1, valve plate 12 interior bottom water coolants are opened, and cool off by 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.
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 art will be appreciated that, above-described embodiment only is that the present invention is described, and be not as limitation of the 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 above-described embodiment, modification etc.
