Abstract

The utility model relates to a device for sealing tail of a novel rotary soda cooling furnace, which is mainly characterized in that the furnace body and a discharging position are provided with a mechanical sealing device respectively, wherein the mechanical sealing device consists of a movable ring sealing seat, a fixed ring sealing seat, a movable ring, a fixed ring, an adjusting spring, an adjusting screw and a fixed ring cushion plate; the movable ring sealing seat is fixed on the tail cover of the furnace body; the fixed ring sealing seat is fixed on the discharging device; the movable ring is embedded in the movable ring sealing seat; the fixed ring is movably embedded in the fixed ring sealing seat; the movable ring is contacted with the fixed ring; the adjusting spring is connected with the fixed ring by the fixed ring cushion plate; and the adjusting screw adjusts the looseness of the movable ring and the fixed ring by the adjusting spring. By adopting the technical scheme, the device converts the cylindrical surface sealing of the sealing surface into the end surface sealing, has reliable sealing, can eliminate the effect of the axial jumping and radial jumping of the rotary equipment on the sealing, and can improve the working condition when the equipment runs.

Description

The cool alkali stove of novel rotation stove tail sealing device

Affiliated technical field

The utility model relates to tightness system, is specifically related to the cool alkali stove of a kind of novel rotation stove tail sealing device.

Background technology

At present, the revolution cooling apparatus uses very wide in chemical industry, this equipment body is done turning motion, the discharging device housings is static, and the contact site uses packing seal, this sealing structure weak effect, dust is easily revealed, contaminate environment, and cause equipment body and discharging equipment operation condition poor, break down easily.

Summary of the invention

In order to overcome the deficiency that existing sealed structure exists, the purpose of this utility model is the cool alkali stove of the novel rotation stove tail sealing device of a kind of good sealing effect of design.

For achieving the above object, the technical solution adopted in the utility model is to be provided with mechanically-sealing apparatus at body of heater and discharging position.

Described mechanically-sealing apparatus is made up of rotating ring sealing socket, stationary ring sealing socket, rotating ring, stationary ring, adjustment spring, adjustment screw and stationary ring backing plate, described rotating ring sealing socket is fixed on the body of heater tail-hood, described stationary ring sealing socket is fixed on the drawing mechanism, described rotating ring is embedded in the rotating ring sealing socket, described stationary ring activity is embedded in the stationary ring sealing socket, described rotating ring contacts with stationary ring, adjust spring and is connected with stationary ring by the stationary ring backing plate, the adjustment screw is adjusted elasticity between rotating ring and the stationary ring by the adjustment spring.

Be provided with the returning charge flight with the corresponding body of heater tail-hood of described tightness system inboard.

Because the utility model has been taked technique scheme, make trim be converted into mechanical seal by the cylindrical surface sealing, use a kind of exotic materials of self-lubricating, rely on the stretch compensation apparatus for rotating axial movement value of spring.

The beneficial effects of the utility model are that sealing is reliable, can eliminate apparatus for rotating axial float and the diameter run-out influence to sealing, can improve the equipment operation condition.
