The invention provides an air flue gate door comprising a connecting part, an electric control device, a gate door, a gate door bin, a power mechanism and a transmission mechanism. The gate door bin is fixedly arranged above the connecting part, and the gate door is arranged inside the gate door bin, and the portion, making contact with the gate door bin, of the top of the connecting part is provided with a through groove for enabling the gate door to fall into the connecting part. The air flue gate door is characterized in that a spring switch capable of controlling a motor to be started andstopped is further arranged, the power mechanism comprises the motor and a reduction gearbox matched with the motor, the transmission mechanism comprises a thread rod and two linear sliding rods, thelower end of the thread rod is connected with the middle position of the gate door through a bearing pedestal, the linear sliding rods are arranged on the two sides of the gate door correspondingly, the two sides of the gate door are each fixedly connected with a sliding rod sleeve, and the linear sliding rods on the two sides are sleeved with the sliding rod sleeves. An operator can control a door plate remotely through a controller, and the opening and closing states of the gate door can be known in real time through the spring switch.
Description
technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an air duct shutter door. Background technique [0002] In the large dust removal and desulfurization system and the boiler system of the thermal power plant, there are flue flue gas flow channel conversion devices, which are used in the flue gas conversion between the operating system and the backup system, and when the equipment fails, and the bypass flue; the existing dust removal and desulfurization The flue part of the system and the boiler system of the thermal power plant is equipped with an air duct closing or opening switching door, with original flue gas, clean flue gas, bypass and backup air duct switching doors, which is an important device in the operation of environmental protection equipment . [0003] The prior art patent number is CN207921360U which provides a shutter door for flue gas desulfurization: it includes a pipe body, which is...
