Embodiment Construction

[0017] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 1 As shown, a ring-wrapped dust suppression device for a roadheader of the present invention is formed by connecting two semicircular jet flow devices through connecting pieces.

[0019] The semi-circular jet flow device comprises an air flow chamber 1, an air guide wall 2, a jet atomizing nozzle 5, a water flow chamber 6 and a fixed base plate 12, the air flow chamber 1 is arranged on the outside of the water flow chamber 6, and the shell of the air flow chamber 1 is in contact with the water flow The shell of the chamber 6 is connected or connected by a fixed bottom plate 12 to form a circular ring; six jet atomizing nozzles 5 are arranged equidistantly in front of the water flow chamber 6, and a water inlet pipe 11 is arranged behind the water flow chamber 6, and the water inlet pipe 11 is connected to the quick connector 10, The j...

Abstract

The invention discloses an annular wrapping dust suppression device for a tunneling machine. The annular wrapping dust suppression device for the tunneling machine is suitable for dust-producing control of a cutting head of a coal mine underground integrated excavator. The annular wrapping dust suppression device comprises an annular air knife, a jet flow spraying device and atomizing nozzles. Thejet flow spraying device and the annular air knife are fixed together with a fixed bottom plate and connectors. Six atomizing nozzles are uniformly arranged at the front end of the jet flow sprayingdevice, and an annular air knife device is arranged on the periphery of the jet flow spraying device. A convex inclined plane air guide wall is arranged on the front portion of the annular air knife,and an air outlet seam of 0.5-1.5 mm is formed between the air guide wall. The inner diameter of the jet flow spraying device can be varied by adjusting bottom plates. The annular wrapping dust suppression device for the tunneling machine has the advantages of simple structure, long-lasting durability, dust source suppression, prevention of returning wind carrying water mist and the like, and is suitable for the dust-producing control of the cutting head of the coal mine underground integrated excavator.

Description

technical field [0001] The invention relates to a dust suppressing device, which is especially suitable for controlling the dust source dust produced at the cutting head of an underground tunneling machine in a coal mine. Background technique [0002] The working face of fully mechanized tunneling in coal mines is a workplace where a large amount of dust is generated and concentrated, and dust is the main factor that causes pneumoconiosis, produces coal dust explosions, causes equipment wear and reduces the visibility of the working face. At present, the fully mechanized excavation working face of the coal mine mainly relies on the internal and external spray facilities of the roadheader to reduce dust. However, because the spray is far away from the cutting head, the atomization effect is good, and a large amount of wind in the air duct turns back at the head, causing the water mist to turn back, which not only affects the dust removal effect , and cause the driver's clothe...
