Coal crushing device of thermal power plant

Abstract

The invention discloses a coal crushing device of a thermal power plant. The coal crushing device comprises a first crushing chamber and a second crushing chamber. A feeding opening is arranged on theleft side of the first crushing chamber. An electric telescopic machine is arranged at the upper end of the first crushing chamber. A smashing disc is arranged at the lower end of the electric telescopic machine. Smashing teeth are arranged at the lower end of the smashing disc. Bases are arranged at the lower end in the first crushing chamber. A screening opening is formed in each base. The second crushing chamber is arranged below the first crushing chamber. A crushing device is arranged at the upper end in the second crushing chamber and is composed of rotary motors, rotary shafts and crushing teeth. According to the coal crushing device of the thermal power plant, through the arrangement of the inclined feeding opening, gravitational potential energy is converted into internal energyin the process that coal falls to the base, the smashing teeth are arranged on the smashing disc to be matched with the screening openings in the process that coal briquettes are smashed for the firsttime, the smashing effect is better, and the smashing teeth are protected.

Description

technical field [0001] The invention relates to the auxiliary field of thermal power plant equipment, in particular to a coal crushing device for thermal power plant. Background technique [0002] Thermal power generation mainly generates steam by heating water when oil, coal and natural gas are burned, and converts the chemical energy of the fuel into thermal energy. The steam pressure pushes the steam turbine to rotate, and the thermal energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, converting the mechanical energy into Electric energy, my country's thermal power plants mainly burn coal, and the pulverization operation before coal combustion is an important link. The traditional pulverization device only performs one pulverization operation, which makes the pulverization effect not good enough, cannot fully burn during combustion, and cannot Dust removal will cause air pollution. Contents of the invention [0003] The...
