Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, a boiler pulverized coal pipeline comprises a feed barrel 1, a switch mechanism and a pulverized coal pipeline body, wherein a feed inlet 100 is formed in the upper left end of the feed barrel 1, a fine powder channel 101 and a coarse powder channel are formed in the feed barrel 1, a first vibrating screen 2 and a second vibrating screen 3 are sequentially arranged on the fine powder channel 101 from top to bottom, the first vibrating screen 2 and the second vibrating screen 3 are obliquely arranged from left to right, the meshes of the first vibrating screen 2 are larger than those of the second vibrating screen 3, and the first vibrating screen 2 and the second vibrating screen 3 are both in the prior art. The lower end of the fine powder channel 101 is provided with a fine powder discharge hole 103, the coarse powder channel sequentially comprises an impurity storage area 104 connected with the right end of the first vibrating screen 2 in a matching way and a coarse powder blanking area 105 connected with the right end of the second vibrating screen 3 in a matching way from top to bottom, the lower end of the coarse powder blanking area is provided with a coarse powder discharge hole 106, and a partition plate 5 is arranged between the impurity storage area 104 and the coarse powder blanking area 105. Wherein the fine powder outlet 103 and the coarse powder outlet 105 are funnel-shaped.
