Embodiment 1

Sintering machine bellows end part leak out inside entire sintering system be one it is bigger leak out a little, and the master that leaks out Be divided into two parts: a part is the sealing between water-tight equipment and pallet, and a part is exactly the sealing of water-tight equipment itself.

Currently on the market, the structure either by using counterweight, link mechanism etc. as movable supporting, or use bullet All there is the sealing problem of equipment itself in the sealing device of spring pattern, field working conditions are complicated, transport between water-tight equipment upper and lower box Move it is not flexible, it is serious stuck into foreign matter and lose sealing function；In addition the sealing of gear shaping shape is used under high temperature hostile operating condition Plate is easily deformed and gets stuck, and loses sealing effect；The effect of current moving contact type sealing is undesirable always in a word.

The improvement of sealing structure:

1. since trolley span is big and the characteristic of weight bearing, so that trolley body will appear waist deformation of collapsing under the operating condition of high temperature, In addition the trolley bottom beam deformation of each process is different, it is desirable that sealing device has the characteristic to float up and down, that is, sealing dress Sealing between the upper box 8 set and lower box 9 is a dynamic sealing.According to design idea, in order to improve water-tight equipment itself Sealing performance designs an elastic wave card 1 (such as Fig. 2), the ripple of this structural shape between upper box 8 and lower box 9 Dynamic sealing is dexterously become static seal by plate, improves leakproofness.

2. this elastic wave card 1 uses size corrugated form, up-small and down-big distribution, best arc angle transition was both protected It has demonstrate,proved elasticity and has avoided stress excessive and fracture.

3. in order to keep the fine note of sealing device upper box 8 and trolley to close, it is desired to which upper box 8 has had certain flexibility (just Degree wants small), therefore it is coupled through design block formula stepped plate 4 (as shown in Figure 4) between upper box 8 and elastic wave card 1, pass through The mutual concatenation form of multiple pieces of formula stepped plates 4 not only ensure that local stiffness but also maintain the overall flexibility of upper box 8 (as shown in Figure 5).Elastic wave card 1 is then connected on block formula stepped plate 4 by press strip 2, bolt 3.Lower box 9 is fixed , therefore coupled by bolt with elastic wave card 1 in one piece of second steel plate 5 (boring tapped through hole above) of lateral layout, thus A confined space is formed, prevents the foreign matters such as sintering feed from sticking into sealing device, and influences floating up and down for sealing device.

4. in order to preferably improve the sealing performance of sealing device, other than first of elastic wave card 1 sealing of setting, Inside increase second layer sealing-pressure difference absorption sealing, principle (as shown in figure) is as follows: burning using the exhausting of pallet Operating condition is tied, when first layer has the case where leaking out, 7 or so the two Conferences of the first steel plate generates pressure difference, and pressure difference forces the first steel plate of fritter 7 It is tightly attached to above side plate 10, multiple the first steel plates of fritter 7 are superimposed and (are easy absorption) to one of inner sealing of formation (such as Fig. 5)；First steel plate 7 is connected to upper box by bolt 6.

Dynamic sealing is dexterously converted to quiet close by the utility model in view of the movement between the upper and lower box of equipment itself Envelope, solves the case where foreign matter Caton causes water-tight equipment that cannot run well, improves sealing performance, reduce energy consumption, mention High economic benefit.

Embodiment 2

Seal cover board is improved, following reason is based on:

The sealed cover plate structure of the utility model is as follows:

1. in order to improve adaptive (compactness with deformation trolley) of sealing device, by 3 pieces of linings on trolley traffic direction Plate is designed to 1 block of liner plate, and this structure type enhances the flexibility of sealing device transverse direction, in the place for waist deformation of collapsing using narrow The arrangement form (as shown in figure 11) of sealed liner 11, so that sealing device is preferably bonded each past of operation in real time Vehicle.

2. sealed liner 11 is designed to convex shape, i.e., 11 1 middle side part of sealed liner, which raises into shape, convex block 111, another Middle side part indent is formed with the groove 112 cooperated with convex block 111；On the one hand it positions convenient for the installation of liner plate, on the other hand reduces Sealed liner 11 is by the risk that trolley shovel falls (bolt 12 on all sealed liners 11 bears trolley bring frictional force)；It is convex Type structure is bigger than the windage of straightway, is conducive to the sealing of trolley.

3. cancelling guide plate 13, guide plate 13 and sealed liner 11 are designed to an entirety, turning place uses circular arc R Transition (as shown in Figure 3)；The wearability of sealed liner is enhanced, the service life of sealing device is extended, solves guide plate 13 Replacement problem.

4. often being fallen to solve the attachment bolt 12 of sealed liner 11 and bottom plate 14, corroding stripped thread and lead to liner plate later The problems such as with changing difficulty；Bottom plate 14 cancels threaded hole, using through-hole, a high nut 5 is welded below the through-hole of bottom plate, in not shadow It rings in bottom plate situation flexible, increases the filament snap ring number that bolt is tightened, 12 stress of bolt is more preferable.

Examples detailed above is only a specific embodiment of the utility model, also equal to its simple transformation, replacement etc. In the protection scope of utility model.
