Five, embodiment
To undertake the construction of 1.5 ten thousand tons of/year magnesium reducing furnaces is example.The body of heater that reducing furnace integral body is built by laying bricks or stones by steel structure frame, refractory material, combustion system etc. constitute.Combustion system mainly is made of thermal storage type combustor, pipe-line system and reverser assembly etc.Stove Yao Qiang respectively establishes both sides 6 burners, and per three are divided into one group, and every side has two groups.During one group of one side burning, another group smoke evacuation accumulation of energy; At this moment, the action of two of offside groups of burner correspondences is respectively smoke evacuation accumulation of energy and burning.Every group of burner top is connected with two import and export of two four-way commutators by pipeline.As shown in the figure, described two four-way commutators are made up of valve casing 4, chip 7 and cylinder 1.Valve casing 4 is that round steel pipe makes, and the circumferential surface four directions ventilation of big square hole such as has and imports and exports 12,13,14,15, and each side is equipped with square flange and is connected outward on importing and exporting; A pair of flange 3,5 respectively is equipped with at its two ends, plays seal action.Drive unit adopts gear rack type swing cylinder 1, by axle sleeve 2 itself and valve casing is linked together.Chip 7 places valve casing 4 inside, constitutes sealing and commutation function with valve casing 4; Chip 7 is connected by the cylinder 1 of axle 6 with the outside again, is driven by cylinder 1 and finishes instantaneous reverse.The structure of described chip 7 is: insert respectively in the axle 6 of two sections central openings at the two ends of metal foil 9, and bearing 16 is equipped with at the two ends of axle 6.Bearing 16 is arranged at 4 liang of end flange of valve casing, 3,5 inside, wherein an end axle 6 stretches out valve casing and passes axle sleeve 2 outward and be connected with cylinder 1, also be provided with a pair of direction perpendicular to axle at metal foil 9 two ends of chip 7 with the isometrical circular metal plate 11 of valve inwall, be provided with the filler that seals between this circular metal plate 11 and the bearing 16.The both sides of metal foil 9 penetrate with isometrical " U " shape Stamping Steel Ribbon 8 of valve inwall in, have reed 10 to be connected in the sealing bar with metal foil 9, can make Stamping Steel Ribbon and valve casing 4 inwall close contact.Like this, in the work engineering, the circular metal plate 11 at chip 7 two ends and ball face sealing bar 8 constitutes sealing for the first time, is arranged at circular metal plate 11 and forms sealing for the second time with filler between the axle 6, is made of for the third time the flange of outer end to seal.Two other interface of commutator is connected with smoke exhaust fan with combustion fan respectively, and every typhoon machine is connected with two selector valves, considers that the chip transposition is frequent, and Stamping Steel Ribbon 8 and valve casing 4 all adopt the wear-resistant metal material red copper to make.When implementing the utility model, the chip 7 that cylinder 1 drives in the commutator, it is on the working position, combustion fan is blown into air at room temperature, and smoke exhaust fan is extracted out through burner flue gas (about 150 ℃), and gas is through selector valve, one group of corresponding burner is in combustion regime, one group is in the smoke evacuation state, and one group of corresponding another side burner is in the smoke evacuation state, and one group is in combustion regime.After 40 second time, air cylinder driven selector valve chip rotates 90 °, makes it on another working position.One group of so corresponding burner transfers the smoke evacuation state to by combustion regime, and one group transfers combustion regime to by the smoke evacuation state, and a group of corresponding another side burner transfers combustion regime to by the smoke evacuation state, and one group transfers the smoke evacuation state to by combustion regime.Thereby finish the commutation action of primary combustion device combustion regime.Through 40 second time, the conversion of one action state was finished in 90 ° of air cylinder driven selector valve blade counter-rotatings more so again.
