Adjustable coal mill separator

Abstract

The invention provides an adjustable coal mill separator which comprises a shell, a coarse material return hopper is arranged in the middle of the shell, a discharging pipe is arranged in the middle of the coarse material return hopper, a plurality of discharging pipes are arranged on the top face of the shell, an adjustable stator blade cage mechanism is arranged on the top face of the coarse material return hopper, and a plurality of adjustable blades are arranged on the top face of the adjustable stator blade cage mechanism. A rotor blade cage mechanism is arranged in the middle of the adjustable stator blade cage mechanism, the angle of a stator guide vane is adjusted through the adjustable stator blade cage mechanism, so that the opening degree of the stator guide vane is changed, and the fineness of pulverized coal is adjusted; an operator can conveniently check the angle of the current stator guide vane through the adjusting angle indicating mechanism, so that the angle is accurately controlled and adjusted, the aerodynamic effect of the stator vane cage and the rotor vane cage is further enhanced through the vanes with arc-shaped cross sections, and the service life of the stator vane cage and the rotor vane cage is prolonged. Therefore, the air suction amount can be controlled by adjusting the rotating speed of the rotor driving motor, and adjustment of the pulverized coal concentration is achieved.

Description

technical field [0001] The invention relates to the technical field of coal mill equipment, in particular to an adjustable coal mill separator. Background technique [0002] Although the existing coal mill is provided with a device for adjusting the air speed and air volume in the pulverized coal pipeline, it is still impossible to adjust the fineness and concentration of the pulverized coal as required. In order to improve the combustion efficiency of the coal-fired boiler and reduce the The generation of nitrogen oxides requires a device that can adjust the fineness and concentration of pulverized coal, so as to further improve the combustion efficiency of the boiler and reduce the generation of nitrogen oxides. [0003] According to a pulverized coal concentration adjusting device and a coal mill separator provided by the patent document with the application number of CN201920677835.9, it can be known that the device includes: a baffle plate for adjusting the concentratio...
