Abstract
The utility model discloses a fast manhole opening and closing device of a dry quenching rotating seal valve, and relates to the technical field of coke-resistant mechanical equipment. The fast manhole opening and closing device comprises a pressing plate, at least four supporting lugs evenly distributed on the outer wall of a manhole, tensioning screw rods hinged to the four supporting lugs respectively, fast locking nuts and springs, four through holes are formed in the pressing plate, the tensioning screw rods hinged to the four supporting lugs are arranged to penetrate through the four through holes in the pressing plate respectively, and the springs are arranged on the tensioning screw rods in a sleeved mode and are arranged between the pressing plate and the supporting lugs. The fast manhole opening and closing device has the advantages that the supporting lugs are arranged on the outer wall of the manhole, the four tensioning screw rods are hinged to the supporting lugs, a manhole cover can be dismounted and mounted fast through the springs on the tensioning screw rods, the pressing plate and the fast locking nuts, maintenance time is shortened, work efficiency is improved, the probability that toxic and harmful gas in the rotating seal valve endangers the life safety of maintenance personnel is reduced, labor intensity is lowered, and the long-period stable operation of a dry quenching system is guaranteed.
Description
Technical field
The utility model relates to burnt resistance to mechanical equipment technical field, particularly a kind of manhole fast opening and closing device that is applicable to rotary sealing valve in coke dry quenching manhole.
Background technology
Rotary seal valve (claiming again rotation discharge-service valve, form seal valve) is the key equipment in coke-oven plant's dry coke quenching engineering, is arranged on the dry furnace bottom that puts out, and feeding mouth is connected with vibra feeder, discharging opening is connected in coke-discharging chute.Its effect is the coke that vibra feeder is quantitatively discharged, and under air-tight state, discharges continuously.Be a kind of multi-format rotary rowed glassware with sealing property, discharge that can continuous and quantitative, has again good leak tightness and resistance to abrasion.Be installed on the exit bottom of CDQ device, mainly by valve body, rotor, sealing pair, manhole, frame, chassis, actuating device, automatically form to fat device etc.This equipment is dry unique outlet of putting out stove, requires it steady in a long-term to move.Wherein manhole is furnished with two altogether, Main Function is that inspection in work, repairing and rotor are because of foreign matter jam and the extraneous unique passage processed that is connected, yet now with rotary seal valve manhole plate fastener, being bolt connects, and quantity is larger, therefore be in case of emergency difficult to fast opening and closing manhole, have a strong impact on process and the repair time of robbing, overhauling, cause dry coke quenching and steam turbine thereof to stop production for a long time.Meanwhile, because rotary seal valve internal gas mostly is carbonic oxide, service personnel need be worn oxygen and exhale breath device just can enter work, and dismounting manhole process time is long, and the life security of service personnel has been caused to huge threat.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotary sealing valve in coke dry quenching manhole fast opening and closing device, can effectively shorten manhole disassembly and assembly time, increase work efficiency, reduce the inner toxic and harmful of the rotary seal valve probability that harm occurs to service personnel life security, reduce labour intensity, guarantee dry quenching system long-period stable operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of rotary sealing valve in coke dry quenching manhole fast opening and closing device, comprise pressing plate, be distributed at least four journal stirrups on manhole outer wall, respectively with four stretching screw, quick locking nut and springs that journal stirrup is hinged, described pressing plate is provided with four through holes, respectively through four through hole settings on pressing plate, described spring housing is loaded on stretching screw and between pressing plate and journal stirrup with the hinged stretching screw of four journal stirrups.
Described four rectangular positioned opposite of journal stirrup, described stretching screw lower end is hinged with journal stirrup and coordinate the axis of four bearing pins installing parallel with four journal stirrups by means of bearing pin.
The beneficial effect that adopts technique scheme to produce is: by journal stirrup being set on manhole outer wall, and on journal stirrup hinged four stretching screws, by the spring on stretching screw, pressing plate and quick locking nut, can realize fast assembling-disassembling manhole cover, shorten the repair time, avoid the inner pernicious gas harm of rotary seal valve service personnel safety, reduce labour intensity, guarantee the normal operation of dry quenching system.

In the accompanying drawings: 1, quick locking nut; 2, stretching screw; 3, pressing plate; 4, locking pin; 5, journal stirrup; 6, bearing pin; 7, bearing pin nut; 8, spring; 9, manhole; 10, manhole cover.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Rotary seal valve (claiming again rotation discharge-service valve, form seal valve) is the key equipment in coke-oven plant's dry coke quenching engineering, is arranged on the dry furnace bottom that puts out, and feeding mouth is connected with vibra feeder, discharging opening is connected in coke-discharging chute.Its effect is that the coke that vibra feeder is quantitatively discharged is discharged continuously under air-tight state.It is a kind of multi-format rotary rowed glassware with sealing property, discharge that can continuous and quantitative, there is again good leak tightness and resistance to abrasion, manhole is to check in work, repairing and rotor are because of foreign matter jam and the extraneous unique passage processed that is connected, yet now with rotary seal valve manhole plate fastener, being bolt connects, and bolt quantity is huge many, when needs overhaul, need service personnel to remove tie bolt by cover, inefficiency, for this reason, the utility model provides a kind of manhole fast opening and closing device as depicted in figs. 1 and 2, comprise pressing plate 3, be distributed in manhole 9 structural at least four journal stirrups 5 in outer walls front and back, respectively with four stretching screws 2 that journal stirrup is hinged, quick locking nut 1 and spring 8, described pressing plate 3 is provided with four through holes, with the hinged stretching screw 2 of four journal stirrups 5 respectively through four through hole settings on pressing plate 3, described spring 8 is set on stretching screw 2, and between pressing plate 3 and journal stirrup 5.
Described four journal stirrups 5 are in rectangular layout, and described stretching screw 2 lower ends are hinged with journal stirrup 5 and coordinate the axis of four bearing pins 6 installing parallel with four journal stirrups 5 by means of bearing pin 6.
In concrete use procedure, first on manhole 9 outer walls, weld four journal stirrups 5 of making of steel plate, stretching screw 2 is connected on journal stirrup 5 by bearing pin 6 and bearing pin nut 7, stretching screw can rotate around bearing pin, then successively spring 8, pressing plate 3 are installed on the stretching screw 2 of manhole the same side, used time, by 1 locking of quick locking nut, makes it compress rapidly manhole plate 10.
In sum, the utility model by arranging journal stirrup on manhole outer wall, and on journal stirrup hinged four stretching screws, by the spring on stretching screw, pressing plate and quick locking nut, can realize fast assembling-disassembling manhole cover, shorten the repair time, increase work efficiency, reduce the inner toxic and harmful of the rotary seal valve probability that harm occurs to service personnel life security, reduce labour intensity, guarantee dry quenching system long-period stable operation.
