Novel high-efficiency air door structure capable of preventing spontaneous combustion

Abstract

The invention discloses a novel high-efficiency air door structure capable of preventing spontaneous combustion. The novel high-efficiency air door structure capable of preventing spontaneous combustion comprises a mounting frame, three rotating shafts, a fire extinguishing assembly and a driving assembly, wherein the front and rear side surfaces are both fixedly connected with fixed plates, and the inner side surfaces of the fixed plates are respectively and fixedly connected with the front and rear side surfaces of a protective cover; the outer cambered surfaces of the three rotating shaftsare respectively and rotatably connected with the inner walls of round holes formed in a top plate and bottom plate of the mounting frame, the three rotating shafts are distributed at equal intervals,the middle part of the outer cambered surface of each rotating shaft is fixedly connected with the inner wall of a through hole in the center of a wind shield, and a connecting assembly is arranged on the upper end of each rotating shaft; the fire extinguishing assembly is arranged on the upper surface of a bottom plate of the protective cover; and the driving assembly is arranged on the upper surface of the mounting frame. According to the novel high-efficiency air door structure capable of preventing spontaneous combustion, the control is automatically carried out, so that the manual operation is reduced, the use is convenient, the direction and volume of air inlet are convenient to adjust, and the application range is wide; and the fixed-point fire extinguishing is realized, the position is accurate, the reliability is high, the fire extinguishing speed is high, and the safety is good.

Description

technical field [0001] The invention relates to the technical field of dampers, in particular to a novel damper structure with high efficiency and self-ignition prevention. Background technique [0002] The air door is an important equipment in the boiler air and smoke system. It shuts off or adjusts the air and smoke of the boiler. The temperature of the air and smoke medium of the boiler is relatively high (usually 135°C-350°C). Improper operation can easily cause the air door to spontaneously ignite. In the prior art, the patent with the authorized public number CN 210568543 U discloses a damper for a boiler fume system, including a damper frame, a plurality of door panels, a plurality of door shafts, two damper extension frames, and a plurality of extension doors. A shaft and a transmission mechanism, the damper frame has an opening, the plurality of door panels are placed at the opening of the damper frame, the plurality of door shafts are arranged through opposite side...

Problems solved by technology

[0002] The damper is an important equipment in the boiler air-smoke system. It shuts off or adjusts the air and smoke of the boiler. The temperature of the air and smoke medium of the boiler is relatively high (usually 135°C-350°C). Improper operation may easily cause the damper to spontaneously ignite. In the prior art, the patent with authorized public number CN 210568543 U discloses a damper for boiler air-smoke system, including a damper frame, multiple door panels, multiple door shafts, two damper extension frames, and multiple extension doors Shaft and a transmission mechanism, the damper frame has an opening, the plurality of door panels are placed at the opening of the damper frame, the plurality of door shafts pass through the opposite sides of the damper frame, and are correspondingly connected to the door panels fixed, the damper extension frame is installed on opposite sides of the damper frame, the extension door shaft is formed by extending from opposite ends of the door shaft, the transmission mechanism is fixed on the damper extension frame and connected with the extension door shaft, Although it can prevent the transmission mechanism from being damaged by heat, the safety performance is not high enough, it is inconvenient to adjust the direction and size of the air intake, the application range is narrow, it cannot prevent spontaneous combustion, it cannot realize fixed-point fire extinguishing, and the reliability is low. Therefore, we propose A new damper structure with high efficiency and anti-spontaneous combustion solves the above defects
