Description
The utility model is the invention about metallurgy sintered secret seal apparatus, is used for sintering machine or burning machine head and the tail end or the chassis at middle part and the sealing between bellows, solve between head and the tail two ends chassis and bellows leak out or middle part two adjacent bellows between string wind.
At home, what big-and-middle-sized sintering machine used at present mainly is the elastic floating plate seal arrangement of helical spring type, this device, and sealing plate floats because of the elastic force effect, its top and the contact seal of chassis crossbeam, sealing effect is fair.The shortcoming of this device is: between sealing plate bottom and the box stand, there is not Sealing, only depend on and reduce the gap and reduce and to leak out, the gap is too little then unsteady dumb, so the gap must not be not quite, thereby sealing effect is not ideal enough, again because spring is under the mal-condition of the many dirt of high temperature, and elastic force reduces gradually, adds between upper sealing panel and the box stand easily buildup and get stuck, the resistance of sealing plate come-up is increased, under the condition that resistance increases, elastic force reduces on the contrary, causes sealing plate to float not finally, sealing function disappears, and it is serious gradually to leak out.
In recent years, China is in the research new device, introduction is also brought into use the heavy hammer type four connecting rod float plate seal arrangements that have the mountain flesh plate seals, some sintering plant, the similar device of homemade mountain flesh plate seals on probation, sealing effect is fine, but the life-span of mountain flesh plate is shorter, has influenced this device widespread usage at home.
Abroad, seal arrangement is of a great variety, using more is heavy hammer type four connecting rod float plate seal arrangements, this heavy hammer type four connecting rod float plate seal arrangements, its sealing principle is that weight makes sealing plate produce the come-up motion by four connecting rods, the sealing plate upper plane, keep tight contact condition with chassis and seal, sealing between sealing plate bottom and the bellows, multiple different sealing member is arranged, thereby form the seal arrangement of multiple pattern, introduce according to " agglomerates of sintered pellets " 1981 the 4th phases, between sealing plate bottom and the bellows, mainly contain band mountain flesh plate seals, have the curved plates Sealing, have dual steel plate envelope confidential paper and have to fall excellent Sealing etc. the heavy hammer type four connecting rod floating seal panel assemblies of multiple pattern, these seal arrangement effects are better, but structure more complicated all.
The shortcoming of above-mentioned various heavy hammer type four connecting rod float plate seal arrangements is: the sealing plate that floats is with between the fixing bellows, not direct contact seal, but by indirect sealing part, promptly seal by sealing component flexible or rigidity and motion, the sealing part that this is indirect, be heavy hammer type four connecting rods float the close panel assembly of envelope weak link---the flexible seals life-span is shorter, the easy buildup of the Sealing of rigidity and motion or get stuck, maintenance is difficulty relatively also.
One of purpose of the present invention, be to overcome the shortcoming that the elastic floating plate seal arrangement of above-mentioned helical spring type and heavy hammer type four connecting rod seal plate means exist---sealing plate float and do not adopt the elastic force of spring and adopt the gravity of counterweight, need not four connecting rods or other rod member mechanism between sealing plate and the counterweight, but directly be contained in counterweight on the sealing plate or counterweight and sealing plate are cast as one, flexible or inflexibilty sealing part that need not be indirect between sealing plate and the bellows, but make the same direct contact seal of supporting base that is connected as a single entity with bellows of sealing plate, aim of the present invention is, makes every effort to reach both at home and abroad excellent sealing performance than labyrinth was had with open-and-shut sealing configuration.
Two of purpose of the present invention is for solving the string wind problem between bellows and the bellows, a kind of feasible seal arrangement is provided, and that the envelope closely packed of this respect is put is at present also less.
The aufbauprinciple of this gravity oscillation plate type seal arrangement is seen accompanying drawing.Fig. 1 is the sectional view that is installed on this device of sintering machine head and the tail end, and Fig. 2 is along A among Fig. 1---the sectional view of A line.Fig. 3 is the sectional view that is installed on this device between the adjacent bellows in sintering machine middle part.Fig. 1 and Fig. 3 structural principle are identical, and only the member shape has difference slightly.
This device is made of sealing plate 1, supporting base 2, counterweight 3 and base 4, and each member all is installed among the base, becomes independently also transportable single unit system.When this device was installed on sintering machine, associated part on every side had chassis 5, bellows 6 and bellows seat 7.
Sealing plate 1 among the figure, and its front end is equipped with counterweight 3(or counterweight and sealing plate is cast as one and counterweight is not installed in addition), its rear end upper surface is the plane, its lower end has recessed or the convex cylindrical curved surface.Recessed or the convex cylindrical curved surface of sealing plate 1 lower end, seat is on the protruding of supporting base 2 or concave cylindrical curved surface, intermeshing concavo-convex cylinder curved surface has identical radius of curvature, sealing plate 1 is under counterweight 3 effects, with supporting base 2 is fulcrum, around supporting base swing, its front end bottom, put on the rear end, make that the crossbeam lower plane on plane and chassis 5 keeps in touch state on the rear end.Supporting base 2 has been welded among the base 4 in the manufacture process of device, and base 4 is in the on-the-spot installation of sintering machine, the joint of its two ends and sintering machine wind box seat 7 is welded to each other, thereby after installing on the sintering machine, supporting base 2 comes down to be connected as a single entity with bellows seat 7, at this moment, having only sealing plate is the detachable member of this device, and other is the stationarity member.
This apparatus features is:
Because the connection part between sealing plate and the supporting base adopts bag arc being connected less than 360 ° axle and bearing, making sealing plate in swing, have dual sealing function---the sealing plate upper plane contacts and seals with the lower flat of chassis crossbeam, and the sealing plate bottom is by contacting and seal with bellows with the cylinder curved surface of supporting base.
The advantage of this device:
Because to have only sealing plate is unique detachable member in this device, other is the stationarity member, therefore has reliable sealing function, and more simple in structure, easy to maintenance than the same device of use so far, fault is lacked, the life-span grows (life-span can reach 3 years).
The item that the design and installation of this device should be noted:
For adapting to " waist collapses " phenomenon of chassis crossbeam, on the chassis width direction, sealing plate should be divided into several piece, generally can be divided into 3.Expansion for after adapting to sealing plate and being heated should leave suitable gap between each piece sealing plate, it is expanded after, be not less than 1 mm clearance between the adjacent seals plate, with guarantee sealing plate flexible swing.
On the base of this device, the back is provided with the crossbeam that steel pipe constitutes, and its effect is two interpleural distances of fixed base, and spacing m is left in crossbeam top and sealing plate lower edge.When this device was installed on sintering machine, at suitable position welded limiting buting iron, spacing n was left in spacing buting iron top and sealing plate lower edge.Design and construction the time will leave suitable spacing m and n, and suitable spacing m is used to limit the limit position of putting on the sealing plate front end, guaranteeing when the counterweight accidental, on put the extreme higher position the sealing plate front end do not block operating chassis.Suitable spacing n is used to limit the limit position of putting on the sealing plate rear end, with guarantee sintering machine in maintenance during contrary running the sealing plate rear end do not block chassis.
Sealing plate tail plane thickness partly should be thickeied backward gradually from fulcrum, to adapt to the characteristics of swing wearing and tearing.
