Flue gas baffle door with high sealing structure

Abstract

The invention discloses a flue gas baffle door with a high sealing structure, and belongs to the field of flue gas baffle doors. According to the scheme, through mutual cooperation of storage grooves with sealing plates, sliding rods and reset springs and rotating shafts with first limiting blocks, second limiting blocks and eccentric pressing wheels, when an execution mechanism drives baffles to turn over, under the elastic action of limiting springs, the rotating shafts and the baffles cannot rotate relatively and rotate synchronously, when the baffles and a door frame are closed, the rotating shafts stop driving the baffles to rotate, the rotating shafts rotate relative to the baffles, at the moment, the limiting springs are pressed and contracted, the eccentric pressing wheels rotate relative to rotating grooves, the eccentric pressing wheels are pressed to extend to the sliding rods in the storage grooves from sliding grooves, and the adjacent sealing plates extend out of the storage grooves to form an opposite-closing sealing structure. Compared with a traditional flue gas baffle door, the flue gas baffle door has the advantages that flue gas can be effectively prevented from being exhausted from the adjacent gaps of the baffles, the sealing performance is high, the market prospect is achieved, and the flue gas baffle door is suitable for popularization.

Description

technical field [0001] The invention relates to the field of smoke damper doors, in particular to a smoke damper door with a high sealing structure. Background technique [0002] With the continuous improvement of the country's environmental protection requirements, in thermal heating and other industries that can generate a large amount of smoke, there are also higher requirements for smoke emission indicators. Therefore, professional skills need to be improved correspondingly in all links from boiler combustion to flue gas discharge to the atmosphere. Usually, a flue gas baffle door is installed in the flue of the boiler system to shut off, open, divert and adjust the flue gas. Among them, if the flue gas contains more harmful components, it is difficult for the sealing of the sealing system. Performance requirements will be more stringent. [0003] The smoke baffle door usually adopts the louver type baffle door, and the baffle door can be divided into single-axis singl...

AI Technical Summary

Problems solved by technology

The existing smoke baffle door is not sealed in the closing gap of the baffle, the sealing effect is poor, and the smoke is easy to be discharged from the gap of the baffle. Therefore, we propose a smoke baffle door with a high sealing structure to solve the above problems. question
