Description

The two piece float extension move board type sealing devices of a kind of sintering machine.

The present invention relates to reach between chassis in the iron ore powder sintering technology sealing device between chassis and ground way.

In the past iron ore powder sintering technology, sealing between pallet and ground way is to finish by the unsteady trip of the monolithic plate that embeds in the chassis seal groove, because the operating ambient temperature fluctuation is too big, the very difficult easy on and off of trip plate that floats floats and its two sides is closely contacted with chassis seal groove both sides.Not that wide being stuck of trip plate of floating becomes fixing trip plate, make the slit to occur between trip plate and ground way and leak out; It is narrow to swim plate exactly, though can float by easy on and off, makes trip plate two sides be difficult to closely contact with chassis seal groove two medial surfaces, causes swimming between plate and the seal groove and scurries wind; In addition, pallet is through long-time running, brinelling shortens mutually, and makes the unsteady trip plate with regular length seem long, causes the slit occurring between the adjacent chassis on the one hand and leaks out, on the other hand when the tail chassis unloads the ore deposit, two blocks of trip plates that float of adjacent two chassis clash into mutually and fracture, and cause equipment breakdown to stop above-mentioned several situations, usually in same sintering machine, exist simultaneously, cause the sintering machine air leak rate of air curtain very high.

It is the shortcoming that sealing device was had of feature so that the unsteady trip of monolithic plate to be installed in the chassis seal groove that the present invention has eliminated above-mentioned, be under any temperature of working environment, the cycle of operation can both be avoided simultaneously swimming between plate and seal groove any time and scurry wind, leak out between trip plate and ground way, leak out in slit, adjacent chassis bottom and adjacent chassis two trip plates clash into two piece float extension move board type sealing devices that the phenomenon that fractures takes place mutually.

Sealing device of the present invention is by two piece float extension trip plates, the bar shaped sealing plate, and parts such as flexible compression handle, pulling-down spring are formed.

Float extension trip plate has two, staggered each other joining, each surface has two slotted holes and an ash leakage hole, the effect of slotted hole is to allow float extension trip plate easy on and off unsteady vertically mobile repeatedly with level, its easy on and off is unsteady to be to finish by the supporting role of deadweight and ground way, and its level is vertically mobile repeatedly to be to finish by the pulling-down power that the flexible pressure of compressing handle pushes away effect and pulling-down spring.

The bar shaped sealing plate has two, its cross section is that chamfer is trapezoidal, its working face posts elastic packing media such as heat resistant rubber or asbestos board, the bar shaped sealing plate can float and horizontal moving by easy on and off, squeezing action by deadweight and flexible compression handle makes its side working face closely contact with the seal groove madial wall, sinks to making that working face closely contacts with the upper surface that float extension is swum plate under it by deadweight.

Flexible compression handle has two, constitute by button, handle body and handle bar, the length of handle bar is regulated at any time by bolt, itself and the contacted side of bar shaped sealing plate, be the evagination semicircle, flexible compression handle can swim that the vertical freedom of level moves repeatedly on the plate at float extension, flexible compression handle button is when being subjected to adjacent chassis extruding, in the withdrawal chassis seal groove, and the float extension that passes through the handle bar promotion other end is swum plate, make it to extend, two blocks of float extensions trip plates extend simultaneously dorsad, and stop when its effective length exactly equates with the physical length of place chassis.When tail unloads the ore deposit, adjacent two chassis squeezing actions disappear, be connected on respectively at two ends under the effect of the pulling force that the pulling-down springs on two float extensions trip plate are produced, two blocks of float extension trip plates are all drawn, in the retraction seal groove, two mutual brinellings of float extension trip plate of adjacent chassis and the generation of clashing into the phenomenon that fractures have been avoided.

The button of flexible compression handle has two kinds, and a kind of is high 5-30mm, is squeezed into fully in the time of in working order in the chassis seal groove; Another kind is high 100-600mm, and the chassis breast board is touched on the top just, is not squeezed in the chassis seal groove in the time of in working order, but is used for slit between the shutoff adjacent stations car body, uses during a kind of trolley body heavy wear in back.

A specific embodiment of the present invention is described with reference to the accompanying drawings.

Float extension trip plate (1) and (2) among Fig. 1 and flexible compression handle (3) and (4), each has slotted hole (9) in same position, the effect of slotted hole (9) is to allow float extension trip plate (1) and (2), and flexible compression handle (3) and (4) easy on and off floats and level vertically moves freely.Working face posts bar shaped sealing plate (5) and (6) of elastic packing medium (7) and (8), middle with seal block (11) connection, three's length just equals place chassis physical length, and bar shaped sealing plate (5) makes the elastic packing medium (7) on the working face closely contact with chassis seal groove one madial wall respectively with (8) with (6) by deadweight and the flexible extruding of compressing handle.Bar shaped sealing plate (5) and (6) sink by deadweight, and upper surface of its following working face (7) and (8) and float extension trip plate (1) and (2) is closely contacted, and have realized the sealing between unsteady trip plate and the seal groove.Flexible compression handle (3) and (4) constitutes by button (13), handle body (14) and handle bar (15), and the length of handle bar is regulated by bolt, the button interchangeable, and the effect of flexible compression handle is to promote float extension trip plate to extend.Under the extruding of adjacent chassis, compression handle (3) promotes float extension trip plate (2), compression handle (4) promotes float extension trip plate (1), thereby float extension trip plate (1) and (2) is extended mutually dorsad, and the physical length of effective length after its staggered joining and place chassis stop when equal; When tail unloads the ore deposit, adjacent chassis squeezing action disappears, the pulling force that is produced by pulling-down spring (12) moves float extension trip plate (1) and (2) in opposite directions, all withdraw in the chassis seal groove, two of adjacent chassis mutual generations of clashing into the phenomenon that fractures of trip plate when having avoided unloading the ore deposit, float extension trip plate (1) and (2) and flexible compression handle (3) and (4) are respectively offered an ash leakage hole (10) in same position, prevented that lime-ash from depositing in seal groove, float extension trip plate (1) and (2) sinks by deadweight, and its following working face is closely contacted with the ground way upper surface.The synergy of above-mentioned each parts, thoroughly shutoff between trip plate and ground way, reach leaking out of adjacent stations workshop between trip plate and the chassis seal groove, greatly reduce air leak rate of air curtain.

When the trolley body serious wear, be the flexible compression handle of 100-600mm with the button height, replacing the button height is the flexible compression of 5-30mm handle.

Fig. 2 to Fig. 4 is float extension trip plate, flexible compression handle, part drawings such as bar shaped sealing plate.

Of the present invention have two piece float extensions trip plate sealing devices and the monolithic in the past trip plate sealing device that floats and compare, and has the following advantages:

(1) monolithic in past floats and swims the plate sealing device, floats and swims consolidating of plate and trolley breast plate Measured length usually with actual (tube) length through every different chassis of the degree of wear of long-time running Spend differently, causing float trip plate and trolley breast plate to seem long, the adjacent stations workshop is occurred Leak out in the slit. And of the present invention pair of piece float extension trip plate sealing device, its be staggered two Piece float extension trip plate under the effect of flexible compression handle, extends mutually dorsad, exactly exists again The physical length of its effective length and place chassis stops when equating. Chassis can be touched in the top in addition The effect of the button of breast board, avoided up hill and dale because of float trip plate and trolley breast plate long, adjacent The phenomenon that occurs between chassis leaking out in the slit takes place.

(2) monolithic in past floats and swims the plate sealing device, because chassis long-time running wearing and tearing become Short, the long unsteady trip plate that seems stretches out outside the trolley body, and when unloading the ore deposit to tail, adjacent chassis is stretched Go out two determine to float the trip plates mutually bump fracture, cause the equipment breakdown replacing of need stopping, and this Bright two piece float extension trip plate sealing devices, when tail unloads the ore deposit, two blocks of float extension trip plates, All retract under the effect of pulling-down spring force in the chassis seal groove, can not taking place mutually, bump fractures Phenomenon.

(3) monolithic in past floats and swims the plate sealing device, because the operating ambient temperature fluctuation too Greatly, not that wide being stuck of trip plate becomes fixing trip plate and can not float, make the trip plate with fixing sliding Occurring the slit between the road and leak out, is exactly that unsteady trip plate is narrow, though can float by easy on and off, makes trip Between plate and the seal groove two sides, be difficult to close contact, cause between trip plate and the seal groove and alter wind; And of the present invention pair of piece float extension trip plate sealing device, its trip plate can easy on and off floats and makes Seamless between trip plate and ground way, can by the bar shaped sealing plate, block trip plate and sealing again Leaking out between the groove.

Of the present invention pair of piece float extension trip plate sealing device swum the plate sealing than using monolithic to float The device air leak rate of air curtain reduces about 20%, volume increase about 30%.
