Description

The glass melter air interchanger

The utility model relates to a kind of stove technology, refers in particular to a kind of open and close device of melting furnaces gate, utilizes this device can realize the flow direction of air switching and waste gas.

Glass melter is when work, need are carried air by certain program and are scavenged in kiln in melting furnaces, during work, usually two shoe brake plates on the melting furnaces flue are used as air interchanger, realize the purpose that commutates, when wherein left flashboard falls, right flashboard rises, and the waste gas just flue below right flashboard is discharged, and vice versa, two shoe brake plate alternating motions are with the flow direction of control air and waste gas.In the past, the old-fashioned air interchanger that China adopts is continued to use the wireline transmission always, drive the action of two shoe brake plates, and a shoe brake plate is joined a cover transmission mechanism separately, one cover air interchanger needs adapted two cover transmission mechanisms, during installation, transmission mechanism is mostly on flooring high about ten meters, usually, need on flooring, to hand down to posterity the pre-embedded device of moving device and wire rope pulley frame, also need to adjust the angle of pulley, installs and careless slightlyly will cause that wireline is stuck, rupture, installation under the upstairs house is also pretty troublesome bothersome, and in use fault is more.

The purpose of this utility model is a kind of glass melter air interchanger easy for installation, reliable and stable, simple in structure of design.

Used for achieving the above object technical scheme comprises the left side on two flues that lay respectively at melting furnaces, right two shoe brake plates and the transmission rig that is connected with flashboard, its main points are to utilize chain to interconnect respectively on the top of two shoe brake plates, chain is walked around two sprocket wheels on the crossbeam that is installed in each flue top respectively, when the length of chain should guarantee to make one of them flue to be in opened condition, another flue is in closing condition, a cylinder has been installed on crossbeam in addition, there is a yoke outer end of the piston rod of this cylinder, and utilizes this yoke to be connected with chain; For utilizing hand to operate where necessary, a handwheel is installed in the rotating shaft of a sprocket wheel therein, or the rotating shaft of one of them sprocket wheel is connected with a rotating shaft that is installed in the decelerator on the crossbeam, electronic to realize; Chain utilizes chain folder and bearing pin to be connected with the upper end of flashboard, and flashboard leans against on the flashboard frame that is installed on the flue, and the guide rail that moves up and down for ease of flashboard between flashboard frame and crossbeam has had the muscle of booster action on flashboard.

The utility model has the advantages that owing between two shoe brake plates, utilize the chain of a suitable length to interconnect, when making work, two shoe brake plates itself are counterweight each other, be that offset on flashboard own wt both sides, only there is some frictional force between flashboard and flashboard frame, compare with the original whole flashboard that need spur heaviness, only use very little power now with regard to stretchy; Interchanger originally adopts the wireline transmission, temperature in the flue is generally about 500 ℃, under this high temperature, use all the year round, must change once in 3-5 month, quite trouble, this device adopts sprocket wheel and the chain gear of heat-resistance high-strength degree, life-span generally more than 5 years, has significantly reduced maintenance cost, and flashboard frame is positive and machining is all passed through in the side, good seal performance, action is dexterous; Have this plant area area few again, whole plant is in light weight, low cost.The operator can arbitrarily select for use pneumaticly, electronic or manual by the needs of oneself after being provided with electronic and man-operated mechanism on the transmission mechanism more in addition, particularly when not having propulsion source, can utilize manual operation.

Fig. 1 is the state graph of the utility model after being installed on the flue.

Fig. 2 is the A-A view of Fig. 1.

As shown in the figure: about flue 20 is total two, each all has inside and outside two-layer refractory wall 19,17 and the concrete 15 that is coated on the outside constitute, at two-layer refractory wall 19,17 have thermal insulation layer 18, the flashboard frame 16 of inclination is set on the section of flue 20, flashboard 14 just leans against on this flashboard frame 16, and flue 20 can be closed, base 12 is installed on flue, the framework 25 of sealing is installed on base 12, and this above framework 25 one side to melting furnaces inspection window 9 is set, another side is provided with ventilation opening 23, this ventilation opening 23 can be by sealing framework 25 inner chamber and be opened on flue 20 upper walls mouthful being communicated with near melting furnaces one side with flue 20, when closing flue 20 with convenient flashboard 14, can utilize this ventilation opening to blow to melting furnaces, two guide rails 21 are arranged in framework 25, so that flashboard 14 can be along on this guide rail 21, move down, the top installation crossbeam 8 of framework 25, this crossbeam 8 links to each other two frameworks 25 at its top, on crossbeam 8, a sprocket wheel 7 is installed respectively corresponding to the position of framework 25, after chain 6 or 10 is enclosed within on these two sprocket wheels 7, its two ends utilize bearing pin 13 an and chain folder 11 and a left side more respectively, right flashboard 14 connects, on the axle of the sprocket wheel 7 that is positioned at the left side, a handwheel 1 is installed, and a decelerator 22 is installed on the crossbeam 8 of this side, the axle of sprocket wheel 7 is connected with the output shaft of step-down gear, a cylinder 2 also is installed on crossbeam 8, there is a yoke 4 outer end of the piston rod 3 of this cylinder 2, piston rod 3 utilizes this yoke 4 to be connected with chain 6 or 10, so that can utilize the motion of cylinder 2 chain drive-belts, one transmission case 5 is installed on crossbeam 8, these transmission rigs are covered on the inside.For improving the intensity of flashboard 14, on flashboard 14, be provided with muscle 24.
