Problems solved by technology
The existing coal fine crushing device generally has a very complicated structure and the finely crushed particles are relatively large. At the same time, in the transportation of pulverized coal, it is difficult to control the conveying speed and strength, which easily leads to blockage of the conveying pipeline.

Embodiment Construction
[0013] Referring to the accompanying drawings, the granular coal pulverizing conveyor of the present invention includes a front end opening a granular coal inlet 17 and a rear end opening a casing 18 for pulverized coal outlet 18. In order to facilitate coal addition, a coal feeding hopper 7 is installed on the granular coal inlet 11. At the same time, the pulverized coal outlet 18 is connected with a delivery pipeline, and the delivery pipeline is connected to a pulverized coal burner or a boiler. The box body 1 is cylindrical and arranged horizontally. The inner cavity of the box body 1 is separated from front to back by the box front orifice plate 2 and the box rear orifice plate 3 into a crushing coal chamber 4, a fine crushing chamber 5 and a conveying chamber 6. A rotating roller 8 driven by a coal crushing motor 7 is installed in the coal crushing chamber 4, and a plurality of crushing hammers 9 are densely covered on the cylindrical surface of the rotating roller 8. The...

The invention relates to a pea coal crushing conveyer which comprises a case with a pea coal inlet disposed at the front and a coal powder outlet disposed at the back; the case is cylindrical and is transversely arranged; the cavity of the case is partitioned, from the front to the back, into a coal crushing chamber, a fine crushing chamber, and a conveying chamber by a case front pore plate and a case rear pore plate, wherein the chambers are communicated with each other; a rotating roller driven by a coal crushing motor to rotate is rotatably mounted in the coal crushing chamber; a plurality of crushing hammers are densely arranged on the cylindrical surface of the rotating roller; a rotating shaft driven by a fine crushing motor to rotate is rotatably mounted at the back of the case; the rotating shaft traverses the conveying chamber and the fine crushing chamber, is equipped with fine crushing blades in the fine crushing chamber, and is equipped with fanning blades in the conveying chamber. The crushing conveyer of the invention has the advantages of simple structure, convenient conveying, and good coal powder fine crushing effect.
Description
technical field [0001] The invention relates to the field of pulverized coal burners, in particular to a granular coal crushing conveyor. Background technique [0002] At present, coal is still the main fuel energy. At present, most of the commonly used lump coals are large pieces of lump coal, and small pieces of granular coal are also used. The particle size of coal directly affects the combustion efficiency of coal, thereby directly affecting the heat exchange efficiency and heat production efficiency of boilers or burners. Therefore, for Further pulverization of granular coal particles can improve its combustion effect. The existing coal fine crushing device generally has a very complicated structure and the finely crushed particles are relatively large. At the same time, in the transportation of pulverized coal, it is difficult to control the conveying speed and strength, which easily leads to blockage of the conveying pipeline. Contents of the invention [0003] Th...
