Multi-channel sectional-type bar screen

Abstract

The invention discloses a multi-channel sectional-type bar screen comprising a frame, a screen surface, a vibrator and an under-screen hopper. The screen surface, the vibrator and the under-screen hopper are fixed on the frame; the screen surface is fixed on a screen frame which is connected with the vibrator; and the under-screen hopper is arranged below the screen frame which comprises a first lateral plate, a second lateral plate and a middle lateral plate separating the space between the first lateral plate and the second lateral plate into more than two channels. The invention has simpleand compact structure, low cost, convenient disassembly, great processing capability and high screening efficiency and can realize the scaled multi-channel sectional-type bar screen of a screen machine.

Description

technical field [0001] The invention mainly relates to the field of screening equipment, in particular to a bar screen. Background technique [0002] The vibrating screens being used in engineering are all excited by the vibrator, and then drive the screen box to generate a certain trajectory of vibration. The screen surface of the vibrating screen is usually a metal mesh or a certain size of screen holes are distributed on the screen plate surface. The screen machine vibrates At this time, the materials smaller than the sieve holes pass through the sieve plate, so that the materials on the vibrating screen can be classified. Most of these vibrating screens have a single channel, the screen surface is in the same plane, and the same section of the screen surface maintains an angle with the horizontal plane. [0003] Among the existing vibrating screens, there is a bar screen (cantilever screen) used in the metallurgical industry. The screen frame of the screen machine insta...

Problems solved by technology

If you want to increase the width of the screen machine with this structure, it will be affected by the strength of the screen surface, and it will be difficult to enlarge it; Large damage will affect the overall screening effect of the screen machine. At this time, the entire screen surface must be replaced, which is a serious waste.

[0004] Therefore, most of the existing bar screens use a screen surface with a width of 1.5m. If this width is exceeded, the screen surface will be widened, but the screen surface will still be a whole piece. If the support is added under the screen surface, the number of support bolts will be limited. limit

Due to the closed structure, it is not easy to disassemble. At the same time, the force on the screen surface is uneven, the life of the screen surface is affected, and the size of the screen machine is limited.

In addition, in order to meet the large processing capacity, the bar screen is designed as a diamond structure. Although the structure is compact, it is inconvenient to overhaul. It must be in the form of a mobile trolley, and the cloth is uneven. , it is not convenient to transport materials
