Embodiment Construction

[0020] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited to the following description.

[0021] [Example 1] such as figure 1 As shown, the floor-type screening and crushing device includes an incoming material belt conveyor 1, an incoming material guide pipe 2, a screening machine 3, a crusher 4, and a feeding belt conveyor 5. The outlet of the incoming material belt conveyor 1 and the incoming material guide The inlet of the material pipe 2 is connected, the outlet of the incoming material guide pipe 2 is connected with the feed port of the screening machine 3, the qualified material outlet of the screening machine 3 is connected with the inlet of the funnel-shaped feeding pipe 6, and the funnel-shaped feeding pipe 6 is a funnel-shaped structure with a large top and a small bottom. The unqualified material out...

Abstract

The invention discloses a floor-type screening and crushing device. A material supply belt conveyor (1) is connected with a feed inlet of a screening machine (3) through a material supply guide tube (2). A qualified material outlet of the screening machine (3) is connected with an inlet of a funnel-shaped discharge tube (6). An unqualified material outlet of the screening machine (3) is connected with a discharge outlet of a crushing machine (4) through an unqualified material discharge tube (7). The funnel-shaped discharge tube (6) and the unqualified material discharge tube (7) are partitioned through a partition baffle (8). The big-end-up funnel-shaped discharge tube is adopted for being connected with the qualified material outlet of the screening machine, the height of the funnel-shaped discharge tube is in direct proportion to the screening capacity and the floor height, large-grain-diameter unqualified materials mixed at the qualified material outlet of the screening machine can be subjected to secondary screening and crushing, and the screening area is enlarged. The floor-type layout is adopted, so that the installing space is narrowed; and coal materials collide with the walls of guide tubes under the effect of gravity, repeated screening and crushing are achieved, and the screening effect is good.

Description

technical field [0001] The invention relates to a screening and crushing device for coal, in particular to a building-type screening and crushing device. Background technique [0002] The circulating fluidized bed boiler of thermal coal gangue power plant burns gangue particles with a certain particle size. The coal material contains a large amount of qualified particle size and does not need repeated crushing. The qualified particle size ratio of incoming coal from the coal mine is 40-80%. Due to the screening efficiency and screening area of ​​the screening machines and crushers in the coal handling building of domestic power plants, the screening capacity is not enough and the screening is not clean, which causes frequent overloading of the crushers and causes blockage and shutdown. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a floor-type screening and crushing device that can expand t...
