Abstract

The invention relates to a device for clearing a coal falling pipe in a coal conveying system, which includes a gas storage tank, a main gas pipeline, a unclogging unit and a central control unit, the unclogging unit includes a nozzle, and the nozzle is connected with the main gas pipeline for spraying a soft connection The gas in the air pipe is equipped with a solenoid valve on the nozzle to control the opening or closing of the nozzle; the central control unit controls the working status of the pressure gauge, ball valve and solenoid valve through the information transmitted by the pressure sensor installed on the belt. The coal blocking situation in the coal falling pipe is detected by the detector installed on the main gas pipeline, and the detection matrix group D is obtained; the present invention increases the main gas pipeline and nozzles by setting a clearing device in the coal falling pipe, and through the set special The compressed air injection nozzle uses the pulse solenoid valve to control the air supply time interval, air supply time, air supply pressure and air consumption parameters to adjust the working state of the nozzle.

Description

technical field [0001] The invention relates to the technical field of coal blending and blending combustion in the electric power industry, in particular to a coal drop pipe cleaning device for a coal conveying system. Background technique [0002] At present, the domestic coal price is generally rising. In order to alleviate the pressure brought by the rising coal price to the operators, coal slime has been blended. Due to the high moisture content and large fineness of the coal slime, it is blocked at the coal drop pipe at the transfer station of the coal transportation system. Seriously, after each coal loading, the main method of cleaning the coal drop pipe in the transfer station is still to rely on manual cleaning. Due to the serious coal sticking, the coal hardened on the wall of the tube is very hard, and personnel need to go down to the coal blocking point Cleaning with electric hammer and electric drill, 4-5 places need to be cleaned a day, resulting in a great wa...
