The utility model has good sealing effect and long service life.
Description
Technical field
The utility model relates to a kind of metallurgical equipment, relates in particular to a kind of sealing device of pallet.
Background technology
Pallet has relative motion between chassis in the motion and the fixing bellows slideway in process of production, and for guaranteeing that wind passes through from the chassis bed of material, sealing device just must be set can be by not entering bellows between chassis and the bellows slideway with the assurance extraneous air.
At present, the sealing device of sintering pallet, using more is the sealing device of a kind of pair of leaf spring form.As Fig. 1 institute, by spring 1, locating shaft 2, seal groove 3, sealing plate 4 and flat spring 5 are formed; Spring 1 is in order to guarantee moving up and down of sealing plate, and flat spring 5 works to intercept air.But, in the process of using, can find, can enter and be full of the space of leaf spring by the gap of sealing plate and seal groove in the short period at sintering machine afterbody high concentrate dust, hinder sealing plate and move up and down, and then make the sealing device inefficacy.In addition, under the effect of alternating thermal stress, flat spring also is easy to occur the phenomenon of elastic failure, makes sealing device lose sealing function.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of good sealing effect, and is heat insulation, and the pallet sealing device of long service life.
For achieving the above object, pallet sealing device described in the utility model comprises locating shaft, seal groove, sealing plate, spring and steady pin;
Described sealing plate is arranged on the opening part of described seal groove, constitutes enclosed construction with described seal groove;
Described locating shaft passes seal groove and the sealing plate that is provided with the through hole suitable with its diameter of axle respectively, and fixedlys connected with described sealing plate through described steady pin;
Between described seal groove and described sealing plate, be provided with described spring;
The end face that described sealing plate contacts with described spring is provided with flexible sealing plate and flat spring, and described flexible sealing plate contacts with the inner wall sealing of described seal groove;
The upper surface of described flat spring is provided with a pressing plate, and described pressing plate is fixed on described flexible sealing plate and flat spring on the described sealing plate through set bolt.
Further, described flexible sealing plate be shaped as bowl structure, and the edge is provided with crimping; The edge of described flat spring is installed in the crimping of described flexible sealing plate.
Further, between described sealing plate and described flexible sealing plate, also be provided with a cushion.
Especially, the material of described flexible sealing plate is a fluorubber.
Especially, the material of described cushion is a rubber asbestos plate.
Pallet sealing device described in the utility model by the elastic force of flat spring, keeps sealing to contact with the inwall of described seal groove the flexible sealing plate all the time, reaches the purpose of sealing.In addition, the utility model has adopted the flexible sealing plate of the fluorubber material of high temperature resistant oil resistant, makes the flexible sealing plate have great high-temperature resistant.The utility model has also added the cushion of one deck rubber asbestos plate material between described sealing plate and described flexible sealing plate, can play heat insulation, oil removal; dustproof; part intercepts the effect of air, effectively protects the flexible sealing plate, has improved the reliability and the service life of sealing device.
The utlity model has following some beneficial effect:
1, the inner wall sealing of flexible sealing plate and described seal groove is good;
2, the sealing plate bellows chute surface of can fitting preferably all the time, and can overcome the unevenness that slideway is installed;
3, have effects such as heat insulation, dust-separation, oil removal, effectively improved the service life of sealing device.
