Air outlet temperature and air direction adjusting device for roller disc type coal mill

Abstract

The invention discloses an air outlet temperature and air direction adjusting device for a roller disc type coal mill, and belongs to the technical field of coal mills. The air outlet temperature and air direction adjusting device comprises an air inlet pipe, one end of the air inlet pipe is connected with a temperature adjusting cylinder, the other end of the temperature adjusting cylinder is connected with an exhaust pipe, and the other end of the exhaust pipe is provided with an air direction adjusting opening. Due to the fact that the temperature adjusting cylinder capable of adjusting the temperature is arranged, a motor works and rotates to enable a driving gear to rotate, the driving gear drives an annular gear to rotate, the annular gear drives a transmission gear to rotate, a fixing frame connected with the transmission gear rotates, the refrigerating end or the heating end of a semiconductor chilling plate steers, and the semiconductor chilling plate conducts refrigeration or heating. The purpose of temperature regulation is achieved. According to the air outlet temperature and air direction adjusting device for the roller disc type coal mill, the lengths of electric push rods can be telescopically adjusted by arranging the air direction adjusting opening, the lengths of the four electric push rods are different, and the electric push rods and a first rotating base rotate, so that the air outlet pipe rotates to change the angle, a telescopic cover telescopes to avoid gas leakage, and air direction adjustment is achieved.

Description

technical field [0001] The invention belongs to the technical field of coal pulverizers, and in particular relates to a device for adjusting the temperature and wind direction of an air outlet of a roller disc coal pulverizer. Background technique [0002] A coal mill is a machine that breaks coal and grinds it into coal powder. It is an important auxiliary equipment for pulverized coal furnaces. There are vertical mills, high-pressure suspension roller mills, medium-speed micro-powder mills, overpressure trapezoidal mills, and Raymond mills. [0003] The coal grinding process is the process in which coal is broken and its surface area is continuously increased. To add new surface area, the bonding forces between solid molecules must be overcome, thus expending energy. Coal is ground into pulverized coal in a coal mill, mainly through crushing, crushing and grinding. Among them, the crushing process consumes the least energy. The grinding process is the most energy-inten...
