Efficient feeding and stirring device for thermal power station construction

Abstract

The invention discloses an efficient feeding and stirring device for thermal power station construction. The efficient feeding and stirring device for thermal power station construction comprises a feeding box, a preliminary drying box and a shell. The feeding box and the preliminary drying box are arranged on the top of the shell, one end of the preliminary drying box communicates with one end ofthe feeding box, and a feeding port is formed in the top of the other end of the feeding box. An auger is arranged on one side of the interior of the feeding box, one end of the auger is connected with an output shaft of a auger motor arranged on the outer wall of the feeding box, an accelerating device is arranged at the other end of the auger, and the accelerating device is composed of a firstgear, a driving ring, a three-point connecting rod and three second gears. According to the efficient feeding and stirring device for thermal power station construction, through the arranged accelerating device, transferring and movement of the auger with low speed rotation to a crushing tool are convenient, thus the rotating speed of the crushing tool is higher, and cutting and crushing of fuel are more thoroughly; and through the arranged auger, transferring and passing of the fuel and the like from the feeding port to the crushing tool are convenient, thus the fuel and the like are crushedby the crushing tool, and then the fuel is initially crushed to a certain fineness from openings formed in one side of the feeding box.

Description

Technical field [0001] The invention relates to the technical field of thermal power station equipment, in particular to a high-efficiency feeding and stirring device for thermal power station construction. Background technique [0002] Thermal power plant is abbreviated as thermal power plant. It is a factory that uses coal, oil, and natural gas as fuels to produce electricity. Its basic production process is: the fuel is burned in a boiler to heat water into steam, and the chemical energy of the fuel is converted into heat energy. The steam turbine is driven to rotate, and the thermal energy is converted into mechanical energy. Then the steam turbine drives the generator to rotate, which converts the mechanical energy into electrical energy. Before the coal is burned, the coal needs to be crushed and stirred. [0003] At present, the existing mixing devices often have too low efficiency when mixing fuels such as coal and cannot sufficiently pulverize and mix the fuel. Therefore, ...
