Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] like figure 1 , 2 As shown in the present invention, the self-cleaning pneumatic sliding plate isolating door dust cleaning device, the air inlet valve 6 on the air inlet pipe 5 is connected with the compressed air pipeline, and the air outlet pipe 7 is connected with the soot blowing pipe of the pneumatic sliding plate isolating door. The intake valve controls the compressed air pipeline, opens the intake valve 6, and the gas storage tank 3 stores gas. The control circuit controls the pulse solenoid valve 2 to blow high-pressure and high-frequency gas in a regular cycle to remove dust from the door panel track. The solenoid valve 2 is located in the storage tank. Between the gas tank 3 and the check valve 1, the check valve 1 controls the gas flow in the outlet pipe 7, cuts off the flow of the high-temperature and high-pressure gas in the air duct to the pulse...

Abstract

The invention relates to an automatic ash cleaning type pneumatic plugboard isolating door and belongs to the technical field of power station auxiliary engine. The automatic ash cleaning type pneumatic plugboard isolating door comprises an ash cleaning device, wherein the ash cleaning device comprises an air storage tank, the air storage tank is provided with an air intake pipeline and an exhaust pipeline, an air intake valve is arranged on the air intake pipeline, a pulse solenoid valve and a check valve are arranged on the exhaust pipeline, and the solenoid valve is located between the air storage tank and the check valve. When the automatic ash cleaning type pneumatic plugboard isolating door disclosed by the invention is at work, the air intake valve of the ash cleaning device is opened, compressed air enters the air storage tank through the air intake pipeline, a control circuit controls the pulse solenoid valve to periodically blow high pressure and high frequency air to clean the dust on the door panel rail, the check valve controls the air flow direction of the pipeline to prevent the high temperature and high pressure air in the air channel from flowing to the pulse solenoid valve so as to protect the pulse solenoid valve from being damaged by the high temperature and high pressure air.

Description

technical field [0001] The invention belongs to the technical field of power station auxiliary machines, and in particular relates to a pneumatic board isolation door. Background technique [0002] Due to the large amount of coal ash contained in the air of the hot primary air duct of the power station boiler, the interior of the pneumatic sliding plate isolation door installed in this air duct is seriously ash-accumulated, and the door panel switch often fails due to ash accumulation, which affects the safe operation of the boiler. And inspection and maintenance bring hidden dangers and inconvenience. Contents of the invention [0003] In view of the above technical problems, the present invention provides a self-cleaning pneumatic sliding plate isolation door capable of regularly and automatically cleaning dust. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is that a self-cleaning pneumatic sliding plate...
