Problems solved by technology

[0007] After adopting the above structure, the sliding plate type smoke isolation door of the present invention has the following advantages: because the annular airbag in the inflated state presses one surface of the sliding door on one side, and the other surface of the sliding door is pressed on the frame baffle, Therefore, it overcomes the disadvantage that the air bag sealing structure of the prior art can not be adopted and the sealing effect is unsatisfactory, especially the sealing effect between the inflated annular air bag device and the sliding door is very ideal, and the end face of the outlet end of the movable annular frame is pressed Make the sliding door and the frame baffle achieve double sealing, so that the sealing effect is more ideal

Abstract

The invention discloses a plug-in type smoke isolation door, which comprises a rectangular door frame and a plug-in door. On the track frame of the panel door, there is a long through hole for the sliding panel door to move in a straight line on the transverse partition of the two frames, and there is a driving mechanism for pulling and inserting the panel door on the rectangular door frame; The movable rectangular frame is connected to the sealed door frame at the outlet end of the flue, and there is a frame-type baffle that is pressed against the end face of the outlet end of the movable rectangular frame to seal the frame-type baffle. A moving drive mechanism; there is also an inflatable or deflatable annular airbag device inside the sealed door frame, and the annular airbag device presses the sliding door to the frame baffle to seal when it is inflated. The insulating door enables the air bag sealing structure to be applied to the sliding door, and has good double sealing effect, simple structure and low failure rate.

Description

technical field [0001] The invention relates to the technical field of flue equipment in a thermal power plant, in particular to a plug-in type smoke isolation door. Background technique [0002] Due to the need for regular and irregular inspection and maintenance of equipment, a smoke isolation door is installed between the flue outlet of the thermal power plant and other equipment. Partition door, also known as partition door, is also called partition door or thermal insulation gate door. Insulation doors are roughly divided into two types: plug-in door and flap door. The cross-sectional shape of the flue or air duct of the plug-in door is circular, that is, the plug-in door has a round door frame, but it is generally rectangular, that is, a rectangular door frame is used. Rectangular door. [0003] With the advancement of environmental protection projects such as desulfurization and destocking in thermal power plants, the isolation of flue gas in the system equipment ha...
