本发明提供的除尘系统的工作流程是：矿用综掘机12液压箱的冗余压力拖动液压马达3旋转，带动两台煤矿综掘液压风幕集尘风机装置13工作，产生径向射流风幕完全封住综掘工作面的产尘空间，当矿用综掘机12工作时，综掘面的含尘空气无法外溢，只能沿着除尘系统流程轨迹19被抽出式风筒16抽入到除尘风机17中，除尘风机17将含尘空气净化后排入回风巷道22，保证人员位置8的工人的身体健康。The working process of the dust removal system provided by the present invention is: the redundant pressure of the hydraulic tank of the fully mechanized mining machine 12 drives the hydraulic motor 3 to rotate, and drives the hydraulic air curtain dust collection fan device 13 of the two coal mine fully mechanized excavators to work to generate radial jets The air curtain completely seals the dust-producing space of the fully mechanized excavation face. When the mine mechanized excavation machine 12 is working, the dusty air on the mechanized excavation face cannot overflow, and can only be drawn out by the extractable air duct 16 along the process track 19 of the dust removal system. Into the dust removal fan 17, the dust removal fan 17 is discharged into the air return roadway 22 after the dusty air is purified, to ensure the health of the workman at the personnel position 8.
本发明中的煤矿综掘液压风幕集尘风机装置，液压马达带动离心式动轮叶片旋转产生高速风流，由导叶径向射出，沿风机圆形出口形成环形射流风幕，起到封闭尘源作用。采用液压马达驱动风幕集尘风机，液压马达体积小、运转平稳、噪声小，因内阻小，使风机有效功率有所增加，并且免除了原电机的防爆、隔爆设施，使综掘机的集尘工艺有了安全、可靠的保证，同时使设备的结构简单，加工容易，成本运转稳定，噪声低，扩展了“风幕集尘风机”的应用范围，与综掘机配套使用，发挥其处理可呼吸性粉尘的优势。In the coal mine fully mechanized excavation hydraulic air curtain dust collection fan device of the present invention, the hydraulic motor drives the centrifugal wheel blades to rotate to generate high-speed air flow, which is radially injected by the guide vanes and forms an annular jet air curtain along the circular outlet of the fan to seal the dust source. effect. The hydraulic motor is used to drive the air curtain dust collection fan. The hydraulic motor is small in size, stable in operation and low in noise. Because of the small internal resistance, the effective power of the fan is increased, and the explosion-proof and explosion-proof facilities of the original motor are eliminated, so that the fully mechanized excavator The advanced dust collection process has a safe and reliable guarantee. At the same time, the structure of the equipment is simple, the processing is easy, the cost is stable, the noise is low, and the application range of the "air curtain dust collection fan" has been expanded. Its advantages in handling respirable dust.
本发明中的除尘系统在矿用综掘机的前上方左右各安装一台液压风幕集尘风机，利用矿用综掘机的液压系统拖动液压风幕集尘风机，两台液压风幕集尘风机产生径向射流风幕完全封住综掘工作面产尘空间，当矿用综掘机工作时，综掘面的含尘空气无法外溢，只能被抽出式风筒抽入除尘风机，除尘风机将含尘空气净化后排入回风巷道，该除尘系统净化了含尘风流、使粉尘浓度大大降低，使巷道环境得到了根本改善，形成了合理的控尘流场，能够高效的集尘除尘，提高了煤矿的安全与环境保护，有利于工人的身体健康。In the dust removal system of the present invention, one hydraulic air curtain dust collection fan is installed on the front, upper, left and right sides of the mine comprehensive excavator, and the hydraulic air curtain dust collection fan is driven by the hydraulic system of the mine comprehensive excavator. Two hydraulic air curtains The dust collection fan produces a radial jet air curtain that completely seals the dust-producing space of the fully mechanized excavation face. When the mining mechanized excavation machine is working, the dusty air on the mechanized excavation face cannot escape, and can only be drawn into the dust removal fan by the pull-out air duct , the dust removal fan purifies the dusty air and discharges it into the return airway. Dust collection and dust removal improve the safety and environmental protection of coal mines, and are beneficial to the health of workers.
