Vibrating type roller screen

Abstract

The invention relates to a vibrating type roller screen which belongs to the field of vibration screening machinery. The invention aims to solve the problem of screening efficiency influence by roller screen stocking or blockage. The vibrating type roller screen mainly comprises a screen box, a roller type screening surface, a vibrator, a vibration attenuating support device and a base, wherein the vibrator is arranged on the screening box or installed on a side plate of the screening box; the vibrator is a double-shaft straight vibrator or a single-shaft round vibrator; the screening box is installed on the base by the vibration attenuating support device; and a motor drive device of the roller type screening surface and a roller of the screening surface are rigidly connected for participating in vibration or connected by a universal drive shaft without participating in vibration. The screening performance of the screening surface is strengthened, and the screening efficiency and the processing capability are obviously improved. The invention has no stocking or hole blockage and is especially suitable for screening viscous and wet materials containing more water.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a vibrating roller sieve with a vibrating device attached to the roller sieve. Background technique [0002] The roller screen is an ideal screening equipment for screening materials such as coal, coke, ore and limestone in industries such as electric power, metallurgy, chemical industry, building materials, and coal mines. The screen surface is composed of multiple rotating shafts arranged in parallel in the direction of vertical material flow, and the screen holes are movable screens formed by these shafts and the plates on the shafts, which are installed obliquely. It has the characteristics of large material flow rate, high screening efficiency and reliable operation. However, it is easy to pile up materials at the feeding end, especially when sieving sticky and wet materials with high moisture content, blockage is more likely to occur. If this accumulation...

Problems solved by technology

However, it is easy to pile up materials at the feeding end, especially when sieving sticky and wet materials with high moisture content, blockage is more likely to occur

If this accumulation or blockage is not cleaned up in time, it will become more and more serious, and even affect the normal operation of the screen machine.
