Technical field
The present invention relates to a kind of seal arrangement, particularly a kind of rotation drum type equipment feeding and discharging end sealing device.
Background technique
The feeding and discharging end sealing device that is applied to rotation drum type equipment such as the rotary kiln of metallurgy and cement industry and dryer is divided into two major types, i.e. radial seal and end face seal basically.The at present main laminated structure that adopts of radial seal, the shortcoming of its existence is that the lamination wearing and tearing are bigger, and lamination and corresponding auxiliary equipment thereof need not carry out machining, and sealing effect is relatively poor, and famous in the world cement machinery Chevron Research Company (CRC) Denmark Smith adopts this kind structure.The main at present friction disk type structure that adopts of end face seal, this structure sound friction plate need carry out machining, its sealing effect is better than laminated structure, this adopts this kind structure the famous in the world cement machinery Germany uncle of Chevron Research Company (CRC) power turtledove, but the said firm uses cylinder to give between the sound brake pad and exerts pressure, in many dirt and hyperthermia radiation condition lower cylinder using effect and unsatisfactory.Under many dirt and hyperthermia radiation condition, the Sealing between cylinder piston and sleeve damages easily, causes cylinder leakage tester, and the sound brake pad can't compress, thereby causes the equipment seal failure, reduces running rate.
Summary of the invention
The present invention provides a kind of rotation drum type equipment feeding and discharging end sealing device for solving the technical problem that exists in the known technology, the good sealing effect of sealing device, and the long service life of critical component can improve the running rate of equipment.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of rotation drum type equipment feeding and discharging end sealing device, comprise the fixed muffle on turnbarrel that is fixed on the equipment rotary barrel and the feeding and discharging end that is fixed in equipment, described fixed muffle is sleeved on the outside of described turnbarrel, be connected with moving supporting ring on the described turnbarrel, be connected with the kinetic friction piece on the outside end face of described moving supporting ring; The outer circumferential face of described fixed muffle is provided with kink quiet supporting ring thereon, described quiet supporting ring comprises cylindrical shell and affixed thereon side inner panel, be connected with on the inner side end of described side inner panel and the adaptive static friction block of described kinetic friction piece, described quiet supporting ring is provided with the uniform described kinetic friction piece of many covers and the hold-down mechanism of described static friction block, the described hold-down mechanism of every cover comprises lever, one end of described lever is pressed on the outside end face of side inner panel of described quiet supporting ring, the other end of described lever is connected with extension spring, the fulcrum of described lever is located at lever seat, described lever seat is fixed on the feeding and discharging end of equipment, described extension spring is connected on the described fixed muffle, the fulcrum of described lever is far away apart from its quiet supporting ring end, and is nearer apart from its extension spring end.
The present invention can also adopt following technological scheme:
Described extension spring is connected on the feeding and discharging end of equipment by controlling mechanism, described controlling mechanism comprises the leading screw and the nut that be installed in leading screw on hinged with described extension spring, described leading screw is rack-mount, described support is hinged on the ring flat-plate, and the feeding and discharging end of described ring flat-plate and equipment is affixed.
Described extension spring is provided with the outer protection housing.
Described leading screw is provided with the outer protection housing.
One end of described mounting mechanism is connected with described fixed support by joint shaft bearing, and the other end of described mounting mechanism is connected with described quiet supporting ring by joint shaft bearing.
Advantage and good effect that the present invention has are: 1, the pulling force of extension spring is applied to lever with on the force, give quiet supporting ring and static friction block by lever transmission, be delivered to the kinetic friction piece by static friction block, thereby dynamic and static brake pad is closely contacted, realize excellent sealing.Can effectively adjust the pressure that passes between the dynamic and static brake pad by leverage, because the fulcrum of lever is far away apart from its quiet supporting ring end, nearer apart from its extension spring end, can effectively control hot barrel type apparatus expanded by heating rear spring tensile force down to the influence of the pressure between the sound brake pad, therefore can prolong the working life of dynamic and static brake pad, improve the running rate of equipment.2, because leverage and spring mechanism and controlling mechanism thereof together do not rotate with barrel type apparatus, in actual mechanical process, can adjust the tensile force of extension spring at any time, make the pressure between the sound brake pad be in optimum Working by controlling mechanism.3, the beat motion takes place in barrel type apparatus in hot work, kinetic friction piece fixed thereon is also done same motion, because the mounting mechanism two ends are provided with joint shaft bearing, connection static friction block is thereon followed the kinetic friction piece and is done the beat motion, thereby guarantees to fit tightly between the sound brake pad.
