Embodiment Construction
[0013] With reference to the accompanying drawings, the pulverized coal fine crushing and conveying integrated machine of the present invention includes a box body 1 with a coal lump inlet 11 at the front end and a pulverized coal outlet 12 at the rear end. In order to facilitate coal addition, a coal inlet 11 is equipped with a coal feeding hopper 7 . At the same time, the pulverized coal outlet is connected with a delivery pipeline, and the delivery pipeline is connected to a pulverized coal burner or a boiler furnace. The box body 1 is cylindrical and arranged horizontally, and a rotating shaft 2 arranged along the central axis direction and driven by a motor 3 is installed in the box body 1, wherein a driven pulley 21 is installed on one end of the rotating shaft 2, and the power output of the motor 3 Driving pulley 31 is installed on the shaft, and belt 8 is connected between the above-mentioned two pulleys. The inner cavity of the box body 1 is divided into a coal crushi...

The invention relates to a coal powder fine smashing and conveying all-in-one machine. The coal powder fine smashing and conveying all-in-one machine comprises a box body, wherein the front end of the box body is provided with a coal briquette inlet and the rear end of the box body is provided with a coal powder outlet. The box body is cylindrical and is arranged transversely. A rotating shaft which is arranged in the axis direction of the box body is installed in the box body in a rotatable mode, and the rotating shaft is driven by a motor. An inner cavity of the box body is divided into a coal smashing cavity, a fine smashing cavity and a conveying cavity from front to back through a front partition plate and a rear partition plate, wherein the coal smashing cavity, the fine smashing cavity and the conveying cavity are communicated with one another, a through hole is formed in the center of the front partition plate, and a through hole is formed in the center of the rear partition plate. A smashing hammer is installed on the portion, in the coal smashing cavity, of the rotating shaft. Coal smashing blades are installed on the portion, in the fine smashing cavity, of the rotating shaft. Fan blades are installed on the portion, in the conveying cavity, of the rotating shaft. The coal briquette inlet is communicated with the coal smashing cavity. The coal powder outlet is communicated with the conveying cavity. The coal powder fine smashing and conveying all-in-one machine has the advantages of being simple in structure, capable of conveying coal conveniently, and good in coal powder fine smashing effect.
Description
technical field [0001] The invention relates to the field of pulverized coal burners, in particular to an integrated pulverized coal crushing and conveying machine. Background technique [0002] At present, coal is still the main fuel energy. In addition to its application in large-scale industrial furnaces, it is also widely used in small and medium-sized pulverized coal boilers or numerous pulverized coal burners. Since the particle size of pulverized coal directly affects the combustion efficiency of coal, it directly affects the heat exchange efficiency and heat production efficiency of the boiler or burner. The existing pulverized coal fine crushing device generally has a very complex structure and the finely crushed particles are relatively large. At the same time, it is difficult to control the conveying speed and force during the pulverized coal conveying, which easily leads to blockage of the conveying pipeline. Contents of the invention [0003] The technical pr...
