Abstract
The utility model discloses a three-layer sealing pneumatic door. The three-layer sealing pneumatic door comprises an open-close air cylinder, a shell frame, abrasion-resisting baffles and other structures, wherein the abrasion-resisting baffles are divided into three layers which are evenly distributed in the shell frame, the open-close air cylinder can respectively control any one of the abrasion-resisting baffles, the thicknesses of the abrasion-resisting baffles on the two sides are equal, the abrasion-resisting baffle in the middle layer is thinner than the abrasion-resisting baffles on the two sides, the heights of the abrasion-resisting baffles on the two sides are equal, and the abrasion-resisting baffle in the middle layer is smaller than the abrasion-resisting baffles on the two sides. The three-layer sealing pneumatic door has the advantages of being reasonable in structure, easy and convenient to operate, high in machining quality, good in work environment, safe, reliable and the like.
Description
Technical field
the utility model relates to the pneumatic door device of a kind of sealing, is particularly applicable to need in the six road parts of thermal power plant the three-layer sealed pneumatic door of the isolated occasion of shutoff fast.
Background technique
the leakproofness of spile type isolating door is better than baffle-type air door, is usually used in such as coal pulverizer inlet hot-flow flue, and many engineerings are due to this Men Buyan, and while stopping grinding, hot blast flows into and burns out belt coal-feeding machine; Combustor inlet isolating door, because coal powder density is high and stop grinding maintenance safety requirement, has spile type isolating door only and just can meet the isolated requirement of abrasionproof; Flue gas air door before deduster, as considered, deduster maintenance must adopt spile type isolating door.
the conventional spile type isolating door that present most occasion is used all adopts door-plate bottom to be furnished with guide wheel and road wheel is realized mobile, door-plate propulsion cylinder not only will overcome the friction between road wheel and guide rail, friction between guide wheel and guide rail, also to overcome the resistance that dust stratification brings simultaneously, once dust stratification is serious, make total frictional force become geometrical progression to rise, cause door-plate to move and be obstructed, cause air door seal failure.All there is the defect fitting badly in all power plant, for example, when coal pulverizer inspection, maintenance, hot blast cannot completely cut off, and can only take that coal pulverizer is exported to fast valve and open always, is communicated with burner hearth, once combustion chamber draft fluctuation becomes malleation, has great human injury hidden danger.These defects have greatly affected the overall operation of equipment, even may cause the major accidents such as blowing out.
Model utility content
the open a kind of two baffle plate hermetic seal pneumatic door devices of the utility model, its objective is provide a kind of rational in infrastructure, operate easy and convenient, quality of processing is high, good work environment, strong, the safe and reliable two baffle plate hermetic seal pneumatic door devices of seal.
for achieving the above object, the utility model is achieved through the following technical solutions.A kind of three-layer sealed pneumatic door, comprises and it is characterized in that structures such as opening and closing cylinder, case frame, wear-resistant baffle plate: wear-resistant baffle plate has three layers, is evenly distributed in case frame.
described keying cylinder can be controlled respectively arbitrary wear-resistant baffle plate.
being of uniform thickness of described both sides wear-resistant baffle plate, mesosphere wear-resistant baffle plate is thinner than both sides wear-resistant baffle plate.
the height degree of described both sides wear-resistant baffle plate is the same, and mesosphere wear-resistant baffle plate height is less than both sides wear-resistant baffle plate.
the beneficial effects of the utility model are easy to operate by the little wear-resistant baffle plate in mesosphere, and the proportion of goods damageds are little, are easy to safeguard, keying that can be good to accident, increases stabilization of equipment performance, is equipment and unit safety operation, and munificent condition has been created in failure-free operation.
