A waste heat boiler flue automatic pressure relief baffle structure

Abstract

The invention discloses an automatic pressure relief damper structure of a waste heat boiler flue. The automatic pressure relief damper structure comprises a blade, wherein uniformly distributed connecting holes are formed in the left end of the blade; the surface of the left end of the blade is fixedly provided with gravity center regulating plates; an opening in each of the upper and lower ends of the blade is fixedly connected with an end part sealing plate through a bent reinforcing rib, and a slot-type reinforcing rib is arranged between the two groups of end part sealing plates; the outer surface of each of two ends of the slot-type reinforcing rib is fixedly provided with a top end reinforcing rib, and the surface of the slot-type reinforcing rib and the blade are fixedly provided with uniformly distributed crossing reinforcing ribs respectively arranged at upper and lower sides of the gravity center regulating plates; the top end reinforcing ribs and the crossing reinforcing ribs are additionally arranged at a rotating shaft of the blade, so that the service life of the rotating shaft of the blade in the using process of a damper can be prolonged; and the automatic pressure relief damper structure can be automatically closed through the gravity center regulating plates and can be automatically opened according to air flow of the flue during use.

Description

technical field [0001] The invention relates to the technical field of flue baffles, in particular to a waste heat boiler flue automatic pressure relief baffle structure. Background technique [0002] The flue of the waste heat boiler usually needs to be installed with a baffle, which will not fall into rainwater or dust during use. The baffle will be damaged due to heat and other reasons during use, and the existing flue baffle has a single structure. The materials used cannot meet the standard specifications, and will be damaged after a long time, cannot meet the conditions of use, and cannot achieve the effect of automatic shutdown. In terms of maintenance, it consumes a lot of manpower and financial resources, which also brings difficulties to normal production. Unnecessary trouble, for this reason, we propose a waste heat boiler flue automatic pressure relief baffle structure. Contents of the invention [0003] The object of the present invention is to provide a wast...
