Rotary drum screening device and screening system

Abstract

The invention provides a rotary drum screening device and a screening system, and belongs to the technical field of urban construction. The rotary drum screening device comprises a driving mechanism, a rack, a screening device and a water feeder, wherein the screening device is obliquely mounted on the rack; the driving mechanism is connected with the screening device; the screening device comprises a rotary drum, a feed opening and a discharge opening; the rotary drum comprises a screen mesh, a first fixing frame and a second fixing frame; the first fixing frame and the second fixing frame are oppositely mounted at the two side ends of the rack separately; the two ends of the screen mesh are connected with the first fixing frame and the second fixing frame separately; the feed opening and the discharge opening are formed in the rack; the feed opening communicates with the rotary drum; the discharge opening is formed in the part under the rotary drum; a stamping bearing tube is mounted in the rotary drum; a plurality of flushing holes are formed in the stamping bearing tube; and one end of the stamping bearing tube is connected with the water feeder, and the other end is connected with the end, away from the water feeder, of the rotary drum. The screening system comprising the rotary drum screening device is simple in structure, high in screening efficiency, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of urban construction, in particular to a drum screening device and a screening system. Background technique [0002] In modern municipal engineering, urban construction is becoming more and more modern, and the construction of some infrastructure, such as land reconstruction or subway construction, is inseparable from basic land construction. In this construction, more sludge waste soil is often produced. [0003] However, the existing methods for dealing with the mud and waste soil produced during shield tunneling basically use the mud transport unit to transport the generated mud and soil to the designated waste dump for dumping, and some construction units will The generated slag slurry is condensed through the equipment installed on site and added with chemical reagents, and then transported and disposed of after the dehydration effect is achieved. The above-mentioned treatment methods treat the sympt...
