Abstract
The invention provides a feed sealing device for a rotary drying machine and an assembling method. The feed sealing device for the rotary drying machine is characterized in that a feeder casing is arranged at one end of a drying machine cylinder, cylinder end plates are arranged on the upper portion of the drying machine cylinder, stuffing box seats are arranged on the end plates, bearing blocks are mounted on the upper portions of the stuffing box seats, bearings are mounted in the bearing blocks, and sealing shells are mounted through studs and nuts and are filled with V-shaped stuffing, hole rings and square stuffing through stuffing box glands. According to the assembling method, weld leg height of the studs of the stuffing box seats is controlled through control of spot welding, chamfers of circumferential holes of flanges of the stuffing box seats are guaranteed, an anti-loosening agent shall be smeared during screwing of the nuts and a feeler gauge is used for inspecting to guarantee gapless contacting surfaces of the stuffing box seats and the cylinder end plates. By the feed sealing device, the problems of loosening and shedding of jointing and fastening members of the stuffing box seats for feed sealing can be solved during operation of the drying machine, and continuity of production operation is guaranteed. The feed sealing device is applicable to devices and methods for sealing of feed ports of drying machines.
Description
Technical field
The present invention relates to petrochemical industry major technologies and equipment, be specifically related to a kind of rotary dryer entrance lock and assembly method.
Background technology
Before the present invention proposes, PTA, CTA tubular type rotary dryer for many years feeding seal part be association of activity and inertia place often because of stuffing-box seat closing the becoming flexible of securing member, coming off causes equipment sealing poor, material leaks, and even equipment cannot normally move, and brings very large potential safety hazard to production.
Summary of the invention
In order to overcome the shortcoming of existing drying machine charging, the present invention proposes a kind of rotary dryer entrance lock and assembly method.This device and method is closed the foot welding height, the each Hole chamfering of stuffing-box seat circumference of flange of stuffing-box seat double-screw bolt, will be smeared locking dose and detect stuffing-box seat and the gapless process of cylindrical shell end plate contact-making surface, solution drying machine feeding seal handle and fastening technical problem with clearance gauge when closing nut by control point electrode holder.
The technical scheme that technical solution problem of the present invention adopts is:
In drying machine feeding seal stuffing-box seat installation process, after double-screw bolt puts together on cylindrical shell end plate, spot welding is fixed, then stuffing-box seat and centering thereof are installed, and seal casinghousing, filler, orifice ring parts are installed.
After double-screw bolt point is welded on end plate, also should be noted that a bit, be exactly that spot welding double-screw bolt exists leg, handle between stuffing-box seat and cylindrical shell end plate closes and just has gap like this, in equipment running process, will cause leaking of material, this cannot accept, so in order to ensure the sealing of drying machine feed end, stuffing-box seat has also done corresponding improvement, the each hole of stuffing-box seat flange increases chamfering, avoid double-screw bolt spot welding leg, so just reach the sealing that ensures feed end, can solve again feeding seal stuffing-box seat closing the problem that securing member becomes flexible, comes off.
Drying machine feeding seal mechanism forms: be provided with charger housing in drying machine cylindrical shell one end, be provided with cylindrical shell end plate on drying machine cylindrical shell top, on end plate, be provided with stuffing-box seat, bearing block is equipped with on stuffing-box seat top, bearing is housed in bearing block, by double-screw bolt and nut, seal casinghousing is installed, in seal casinghousing, is filled with V-arrangement filler, orifice ring and square filler by gland.
Assembly method concrete steps:
1, control point electrode holder closes the foot welding height of stuffing-box seat double-screw bolt, and requirement must not be greater than 2mm, and the polishing of postwelding solder joint is round and smooth;
2, the each Hole chamfering 5x45 ° of stuffing-box seat circumference of flange, just can avoid the leg of double-screw bolt spot welding in installation process, ensure the sealing between drying machine end plate and stuffing-box seat;
3, after stuffing-box seat installs, to smear locking dose when closing nut, nut will use all-metal locking nut, prevents that in equipment operation process, producing vibrations causes becoming flexible, coming off of nut.
4,, after stuffing-box seat puts together on end plate, detect and confirm stuffing-box seat and cylindrical shell end plate contact-making surface gapless with clearance gauge.
Good effect, adopts sealing device of the present invention and the method can be at drying machine in operation process, prevents that feeding seal stuffing-box seat from, closing the problem that securing member becomes flexible, comes off, having ensured the continuation of production run.The apparatus and method application of suitable drying machine charging aperture sealing.

Detailed description of the invention
Feeding seal mechanism forms:
According to the figure, be provided with charger housing in drying machine cylindrical shell one end, be provided with cylindrical shell end plate on drying machine cylindrical shell top, on end plate, be provided with stuffing-box seat 1, bearing block 2 is equipped with on stuffing-box seat top, bearing 3 is housed in bearing block, by double-screw bolt 4 and nut 5, seal casinghousing 6 is installed, in seal casinghousing, be filled with V-arrangement filler 8, orifice ring 9 and square filler 10 by gland 7.
Feeding seal mechanism installation step and method:
1, control point electrode holder closes the foot welding height of stuffing-box seat double-screw bolt, and requirement must not be greater than 2mm, and the polishing of postwelding solder joint is round and smooth;
2, the each Hole chamfering 5x45 ° of stuffing-box seat circumference of flange, just can avoid the leg of double-screw bolt spot welding in installation process, ensure the sealing between drying machine end plate and stuffing-box seat;
3, after stuffing-box seat installs, to smear locking dose when closing nut, nut will use all-metal locking nut, prevents that in equipment operation process, producing vibrations causes becoming flexible, coming off of nut.
4,, after stuffing-box seat puts together on end plate, detect and confirm stuffing-box seat and cylindrical shell end plate contact-making surface gapless with clearance gauge.
