Problems solved by technology

The damper of the existing circulating fluidized bed boiler is adjusted by welding a bolt on the adjustment handle, and making the bolt slide in the positioning plate with the arc-shaped slot, and then tighten it with the ingot nut to position it. , due to the vibration in the air duct, it is easy to cause the adjustment nut to loosen and cause the failure of the air adjustment opening
The damper plate and the bearing are connected with M6 bolts and nuts, and they are often loose, causing the damper plate to fall off

Abstract

The invention relates to an improved air-adjusting door for a circulating fluid bed boiler, which can ensure that a door panel is firm and highly stable and ensure that the air-adjusting opening is stable. The improved air-adjusting door comprises the door panel, a flange, a cylinder, a front connecting shaft, a rear connecting shaft, a front bearing seat, a rear bearing seat, a positioning plateand a connecting seat and is characterized in that the door panel is connected with the front connecting shaft and the rear connecting shaft; the front connecting shaft is exposed out of the end partof the cylinder and connected with a connecting sleeve; the connecting sleeve is connected with a handle which is provided with a mounting hole; a positioning device is mounted on the mounting hole; a positioning hole is disposed on the positioning plate; and an adjusting rod is close to the cylinder, exposed out of the handle and vertical to the plane of the positioning plate.

Description

(1) Technical field [0001] The invention relates to the technical field of boiler structures, in particular to an improved damper for circulating fluidized bed boilers. [0002] (2) Background technology [0003] The combustion of the circulating fluidized bed boiler is mainly carried out on the bed surface and in the furnace. The lower half of the furnace is positive pressure combustion. In order to ensure sufficient combustion and reasonable circulating fluidization of circulating fluidized bed boilers, the quality and performance of its damper is the key. The damper of the existing circulating fluidized bed boiler is adjusted by welding a bolt on the adjustment handle, and making the bolt slide in the positioning plate with the arc-shaped slot, and then tighten it with the ingot nut to position it. , Due to the vibration in the air duct, it is easy to cause the adjustment nut to loosen and cause the failure of the air adjustment opening. The air regulating door plate is...
