Description
Technical field
The utility model relates to iron-smelting furnace plugging device, particularly a kind of plugging device of blast furnace lead discharging mouth.
Background technology
Current ironmaking is forced to because production cost pressure is large select the leaded high low price raw material containing lead of impurity that waits to enter stove, though pig iron cost is able to further reduction, but lead is in cupola well enrichment, if discharge can destroy brick lining in blast furnace chamber not in time, bring serious threat to safety in production.Therefore the blast furnace of pre-buried lead discharging groove is had according to crude fuel service condition, lead discharging operation need to be carried out according to plan bottom this type of cupola well.Lead discharging operation is under blast furnace full blast working condition, the liquid lead of cupola well enrichment is discharged with the lead discharging mouth of the boiled cupola well bottom of oxygen hose, liquid lead seals lead discharging oral pore road with refractory mortar again by after the emptying of cupola well lower sides, finally to fit capping locking with the ring flange in flange plate and cupola well lower sides lead discharging oral thermometer face.
Blast furnace is under full blast production status, plumbous just clean than being easier to discharge, but during full blast, cupola well bottom net pressure is comparatively large, has a large amount of gas fire and is mingled with the winding-up of liquid lead, threaten operating personnel's safety at lead discharging operation later stage lead discharging mouth.For avoiding operating personnel's burn and carbon monoxide poisoning, blast furnace often needs step-down checking even to carry out the operation of closed lead discharging mouth after damping down, thus have impact on the productive capacity of blast furnace.
Summary of the invention
The utility model object, for overcoming above-mentioned defect, provides a kind of plugging device of blast furnace lead discharging mouth.
The utility model scheme is: it is characterized in that: plugging device is made up of butt plate, master collet, piston push rod; Master collet right output port is docked fixing with the annulus disk body medium pore of butt plate, the secondary case cylinder that an internal diameter is greater than the short pipe body shape of master collet external diameter is fixed on the described right surface of annulus disk body, the external circle of described circle ring disk is uniform fixes the rectangle steel disc of four right angles towards the right side, rectangle steel leaf length is greater than secondary case cylinder axial length, right section of rectangle steel disc is provided with a rectangular opening, when the secondary case cylinder of butt plate and furnace bottom lead discharging mouth ring flange are fitted, in each rectangle steel disc right section of rectangular opening, insert wedge type latch respectively; Master collet left port welds an interior circle ring disk, and interior annulus surface-welding of facing left fixes a pipe spreader; Piston rod moves and stretches into its right output port of master collet after pipe spreader inner circle is inserted in cooperation and be welded and fixed a disc, the right surface coverage of disc one block of round rubber plate, both implement to be fitted and connected composition piston with six bolts, nut, and piston rod left port fixes welding one piece of round plate; Master collet right section of cylindrical is welded and fixed a right hangers, and a left hangers is fixed in pipe spreader cylindrical stage casing, and hangers is the rectangular plate with a through hole; A steel bar is through after left hangers through hole, and both sides bend to U-shaped steel bar left, and the longitudinal bar end bent in U-shaped steel bar both sides becomes hook, is welded and fixed a cross bar at piston rod left section of cylindrical.
The utility model has the advantage of: 1, substitute and manually block up, the personnel that avoid scald; 2, effectively control coal gas to leak, avoid carbon monoxide poisoning; 3, avoid damping down, checking blocks up on the impact of blast furnace index, thus improve economic benefit.4, easy and simple to handle, safety.
accompanying drawing illustrates:
Fig. 1 is that cupola well lead discharging mouth docks schematic diagram with plugging device.
Fig. 2 is the utility model structural representation.
Fig. 3 is the right view of Fig. 2.
embodiment:
The utility model structure is characterized in that: plugging device is made up of butt plate, master collet 4, piston push rod; Master collet 4 right output port is docked fixing with annulus disk body 10 medium pore of butt plate, the secondary case cylinder 1 that an internal diameter is greater than the short pipe body shape of master collet 4 external diameter is fixed on the described right surface of annulus disk body 10, described annulus disk body 10 cylindrical is uniform fixes the rectangle steel disc 2 of four right angles towards the right side, rectangle steel disc 2 length is greater than secondary case cylinder 1 axial length, right section of rectangle steel disc 2 is provided with a rectangular opening, when the secondary case cylinder 1 of butt plate is fitted with furnace bottom lead discharging mouth ring flange, in each rectangle steel disc 2 right sections of rectangular openings, insert wedge type latch respectively; Master collet 4 left port welds an interior circle ring disk, and interior annulus surface-welding of facing left fixes a pipe spreader 11; Piston rod 7 moves and stretches into its right output port of master collet 4 after pipe spreader 11 inner circle is inserted in cooperation and be welded and fixed a disc, the right surface coverage of disc one block of round rubber plate, both implement to be fitted and connected composition piston with six bolts, nut, and piston rod 7 left port fixes welding one piece of round plate 9; Master collet 4 right sections of cylindricals are welded and fixed a right hangers 3, and a left hangers 5 is fixed in pipe spreader cylindrical stage casing, and hangers is the rectangular plate with a through hole; A steel bar is through after left hangers 5 through hole, and both sides bend to U-shaped steel bar 6 left, and the longitudinal bar end bent in U-shaped steel bar 6 both sides becomes hook, is welded and fixed a cross bar 8 at piston rod 7 left sections of cylindricals.
Its method of work loads full refractory mortar from secondary case cylinder 1 position to master collet inner chamber in advance, whole device is lifted with a long pricker through the right hanger 3 on master collet 4 putting the lead dust phase by 2 people, lead discharging mouth center is aimed at the center of secondary case cylinder 1 dock, secondary case cylinder 1 and furnace bottom lead discharging mouth ring flange are fitted, now four rectangle steel discs 2 can be trapped among on lead discharging mouth ring flange cylindrical, after four wedge type latches being inserted four rectangular openings of rectangle steel disc 2, whole device and lead discharging mouth ring flange compact siro spinning technology, and then with the round plate 9 on sledgehammer impact piston rod 7 right side, refractory mortar is pressed into lead discharging oral pore road in master collet 4.When piston rod 7 refractory mortar pushed the shutoff of lead discharging mouth good after, hook cross bar 8 with the U-shaped steel bar 6 on left hanger 5, after approximately waiting for 15 minutes, shed whole device again, the ring flange cover plate of locking lead discharging mouth, finally clean out the residual refractory mortar in master collet 4, whole end-of-job.
