据苏联《煤炭工业合理化建议与发明》1989年第1期报导,顿涅茨克矿井设计院和中央矿井掘进机械科研设计院共同研制出一种适用于机掘巷道的空气除尘装置.图中所示,是安装在掘进机上的空气除尘装置的外形图.这种除尘装置包括呈П状横截面的汲水箱1,汲水箱是固定在掘进机工作机构3的悬臂2上的,汲水箱通过软管4和直管5与空气清洗装置——通风机、集尘器及尘渣排管等除尘设施(图中未显)相连接,并装有几个呈直角横截面的伸缩式整定段6、7、8.汲水箱壁和伸缩式整定段都打
According to the Soviet Union, “coal industry rationalization proposals and inventions,” No. 1 of 1989 reported that the Donetsk Mine Design Institute and the Central Coal Mining Machinery Research and Design Institute jointly developed a roadway for the machine air dust removal device. Shows the outline of the air dust removal device mounted on the roadheader.The dust removal device comprises a suction box 1 in a cross-section in the shape of a pi, which is fixed to the boom 2 of the boring machine working mechanism 3, The pipe 4 and the straight pipe 5 are connected with dust removal facilities (not shown) of the air cleaning device, such as a ventilator, a dust collector and a dust exhaust pipe, and are provided with several telescopic setting sections 6 , 7,8. Draw tank wall and telescopic setting section are playing
