Arc-shaped surface sliding screen

Abstract

The invention discloses an arc-shaped surface sliding screen. The arc-shaped surface sliding screen comprises a material receiving plate and multiple screen strips. The screen strips are arranged at intervals in the length direction of the material receiving plate. Each screen strip comprises a connecting end and a free end. The connecting ends of the screen strips are fixedly connected with the material receiving plate, the middles of the screen strips are downwards sunken and are in an arc shape, and the free ends of the screen strips are higher than the connecting ends of the screen stripsand / or the material receiving plate. According to the arc-shaped surface sliding screen, the free ends of the screen strips of the arc-shaped surface sliding screen are higher than the connecting endsof the screen strips and / or the material receiving plate, and therefore the problem that the vertical space is not easily technically improved is effectively solved, the installation space of equipment is saved, the technical improvement is facilitated, and the arc-shaped surface sliding screen is simple in structure, low in production cost, high in screening efficiency and high in overall economic benefit.

Description

Technical field [0001] The invention relates to the technical field of fixed screening for mines, in particular to a curved sliding screen. Background technique [0002] At present, when mining coal and other mineral materials, the commonly used conveying device is a belt conveyor, that is, a drive motor drives the conveyor belt to move to realize the transportation of coal and other mineral materials. However, with this kind of conveying method, during the conveying process, the mineral material will generally form accumulation on the conveyor belt. The traditional screening method is to use an inclined fixed screen, such as a bar screen or a grate screen. The material is not easy to disperse, the material with small particle size is easy to jam the screen gap, and the screening efficiency is low without vibration source. Some companies will choose a vibrating screen, but the screen weight of the vibrating screen is fixed. If more materials need to be screened, the efficiency w...
