Description
Technical field
The utility model belongs to technical field of sealing technology, and the sealing device between a kind of sinter cooler waste gas cover and the chassis particularly is provided, and is used to seal the gap between sintering circular-cooler waste gas cover and the chassis.
Background technology
Steel and iron industry belongs to the high energy consumption industry, and SINTERING PRODUCTION is an emphasis energy-saving and cost-reducing in the Iron and Steel Production, leaks Gu this reduces, and for improving the waste heat recovery of sintering cooling exhaust, is of great practical significance.In the production process of sintering cooling, be formed with certain clearance between the fixing waste gas cover and the chassis of operation, the sealing of this gap belongs to movable sealing, realizes that sealing has certain degree of difficulty, is not well solved for a long time.Along with the energy-saving and cost-reducing raising that requires; Sealing between waste gas cover and the chassis is also had higher requirement, Gu this resolves this sealing problem, for improving the thermal efficiency that sintering waste heat reclaims; Improve the economic benefit of waste heat recovery, improve production environment and all have positive meaning.
Summary of the invention
The purpose of the utility model provides the sealing device between a kind of sinter cooler waste gas cover and the chassis, has solved leakage problem, effectively seals the gap between sintering circular-cooler waste gas cover and the chassis, improves the waste gas residual heat rate of recovery and economic benefit.
The utility model comprises waste gas cover 1, backing plate 2, hinge, dustproof cover 4, steel plate 5, movable sealing plate 13, static seal sub-assembly, chassis 14; See accompanying drawing 1.
Backing plate 2 is fixed on the waste gas cover 1; Formed a straight datum level, an end of first hinge 3 links to each other with backing plate 2, and the other end links to each other with steel plate 5; One end of second hinge 6 links to each other with steel plate 5; The other end links to each other with static seal plate 7, and the static seal sub-assembly is between backing plate 2 and movable sealing plate 13, and the axle of first hinge 3 should be parallel with the axle of second hinge 6; For the static seal sub-assembly provides certain free degree between backing plate 2 and movable sealing plate 13, making it can be along the axle rotation of first hinge 3 and second hinge 6.Under the gravity effect, the lower end of each soft graphite 12 can closely contact with the upper surface of movable sealing plate 13 all the time, forms labyrinth seal.Play sealing, the effect of anti-heads.Movable sealing plate 13 links to each other with chassis 14.
The static seal sub-assembly comprises static seal plate 7, pad, bolt 10, setting-up piece 11, soft graphite 12; See accompanying drawing 2..The quantity of soft graphite 12 is 4～8 rows, parallel installation, and setting-up piece 11 links to each other with static seal plate 7, has 2～3 dovetail grooves on the static seal plate 7, and the dovetail tenon on first pad 8 can be so that installation and fixing.Soft graphite 12 is banded, and have heat-resisting, characteristics such as coefficient of friction is little, easy for installation.
Under the gravity effect, formed labyrinth seal between static seal sub-assembly and the movable sealing plate 13, air-flow produces throttle effect in labyrinth seal, can effectively reduce leakage.
Dust cover 4 can prevent that outside dust from falling on the hinge, keeps the flexibility of hinge, and prevents to collide with unexpectedly.
Sealing device between sinter cooler waste gas cover and the chassis is answered the both sides that are arranged in waste gas cover 1 of symmetry, and with chassis 14 parallel installations, and setting height(from bottom) H equates.Under the gravity effect, the sealing device can compensate the wearing and tearing of soft graphite 12 automatically, keeps the effect of sealing.
