Abstract
The utility model relates to a multi-sealing combined pneumatic cold and hot blast isolation door which particularly is used for installing on a boiler of a fuel electric plant or smoke and blast systems of power departments of other enterprises as a cutoff working substance. An opening and closing cylinder is mainly adopted and is installed on a shell body on the outer side of a door board. A locking mechanism is connected with a locking cylinder and is fixed on the shell body. The utility model is characterized in that the door board with dual disk root sealing is placed in the shell body, and the shell body is provided with a sealing air inlet pipe and two cleaning holes on the position of the dual disk root sealing near the door board. During the operation or the maintenance of the systems, the utility model has the advantages of reliable and flexible control and good sealing performance. The multi-sealing combined pneumatic cold and hot blast isolation door can be rapidly opened or closed and can realize remote control. The requirements of the safety, the high efficiency and the low consumption of the fuel electric plant are satisfied to a large degree. In the process of using the multi-sealing combined pneumatic cold and hot blast isolation door, the multi-sealing combined pneumatic cold and hot blast isolation door reduces the phenomenon of ash deposition of a guide rail, reduces failure rate and lightens maintenance cost and the labor strength of maintainers.
Description
Technical field
The utility model relates to the isolated door of the hot and cold wind of a kind of multi-sealed combined pneumatic, specifically is used for being installed on heat power plant boiler or other enterprise's power department air and gas systems do the to dam usefulness of working medium.
Background technology
The isolated door of the hot and cold wind of multi-sealed combined pneumatic is that the auxiliary equipment that source of the gas is used as power source medium and sealing medium is enriched in a kind of thermal power plant of effectively utilizing, and it is arranged in coal pulverizer in the air and gas system, blower fan is imported and exported in the pipeline.Before the utility model was made, in prior art, common in the past isolated door was to offer air intake duct on housing, and the keying cylinder is installed on the housing and fixes, to reach switching purposes.Retaining mechanism connects locking cylinder and is fixed on the housing so that cut out and put in place, loads onto access door then.The isolated door of the pneumatic hot and cold wind of this kind structure is met shortcomings such as thermal deformation is big, bite serious, be not closed completely, leakage point is many, completely cut off door place dust stratification, the shut-in time is long, arrangement form is single, influences the normal operation of system.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of when system's operation or maintenance, can open apace or close, and can realize Long-distance Control, satisfied power plant safety, the isolated door of the hot and cold wind of multi-sealed combined pneumatic efficient, the low consumption requirement largely.
Main solution of the present utility model is achieved in that
The utility model will open and close cylinder 2 and be installed on the housing 1 in door-plate 5 outsides, retaining mechanism 10 connects locking cylinder 8 and is fixed on the housing 1, compress door-plate 5 by the axle overhead cam, load onto access door 4 then, feature is that the door-plate 5 that has dual packing_seal 6 is put into housing 1, and near on dual packing_seal 6 place's housings 1 of door-plate 5 sealing air air inlet pipe 7 is being set.Easily be provided with two clean-out hatch 3 in the track place, housing 1 lower end of dust stratification at isolated door.
Compared with the prior art the utility model has the following advantages:
1, door panel structure: the equipment bulk heat treatmet, the big temperature difference is indeformable, the abrasion resistance height.2, hermetically-sealed construction: adopt dual novel encapsulant and sealed air system, good seal performance.3, control flexibility: adopt pneumatic means to promote door-plate, cylinder opens and closes and locks synchronously the method for designing of door, is convenient to the computer centralized Control, for ease of maintenance and special requirement, and also can on-the-spot manual mode operation.4, control reliability: operating mechanism action safety, quick, can within 20 seconds, finish whole actions; Adopt optimal design and purging system, make the thermal isolation door in use reduce the fouling phenomenon of guide rail, reduced fault rate, alleviated maintenance cost and maintenance personal's labour intensity.5, installation site: look field condition and can carry out installing and using of level, vertical, inclination, position such as vertical, and be provided with a distant place and two kinds of modes of operation on the spot.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model A is to view.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of housing 1, keying cylinder 2, clean-out hatch 3, access door 4, door-plate 5, dual packing_seal 6, sealing air air inlet pipe 7, locking cylinder 8, inlet and outlet connectors flange 9, retaining mechanism 10 etc.After the utility model housing 1 assembly welding is good, the door-plate 5 that will have dual packing_seal 6 is put into housing 1, and sealing air air inlet pipe 7 and two clean-out hatch 3 being set near on dual packing_seal 6 place's housings 1 of door-plate 5, the position of these two clean-out hatch 3 is out the track place, lower end at the easy dust stratification of isolated door.Open and close cylinder 2 be installed on the housing 1 in door-plate 5 outsides fixing, to reach the purpose of switch door-plate 5.Retaining mechanism 10 connects locking cylinders 8 and is fixed on the housing 1 so that door-plate 5 cuts out when putting in place, compresses door-plate 5 by the axle overhead cam and makes the no leakage point of its sealing, loads onto access door 4 then.Inlet and outlet connectors flange 9 is the usefulness that this equipment is connected with system pipeline.
The operation principle of the present utility model and the course of work:
The isolated door of the hot and cold wind of the multi-sealed combined pneumatic of the utility model is installed on the cigarette air channel, must be strict by determining good MEDIA FLOW to installation, in case dress is anti-.The door-plate switching spurs door-plate by the keying air cylinder device by drive link and opens or close along guide rail, also can manual operation during outage.If the pneumatic door butt joint is installed,, install like this and be convenient to operation and maintenance 90 ° or 180 ° of the relative dislocation of pneumatic door with the manually operated door frame plane.Whether want conscientious inspection door body and pneumatic control system to install before the debugging correct, through examine install errorless after, at first, whether reciprocal one of door-plate is out of shape back and forth with this inspection door framework with low discharge by the control stop valve, whether the door-plate motion unblocked.Then stop valve is opened fully, adjusted the door-plate reciprocating speed by adjusting two one-way throttle valves, to close the door be 5 seconds to reach, and the time of opening the door is 10-20 second.The locking time was less than 4 seconds.So can satisfy the normal operation of system.
