Double-layer independent shock excitation screening device used for shield construction muck treatment

Abstract

The invention discloses a double-layer independent shock excitation screening device used for shield construction muck treatment. The device comprises an equipment installation support. An upper-layerbox body and a lower-layer box body are arranged on the equipment installation support. The bottom of the upper-layer box body communicates with the top of the lower-layer box body, an upper-layer screen and an upper-layer excitation motor are arranged in the upper-layer box body, a lower-layer screen and a lower-layer excitation motor are arranged in the lower-layer box body, and the particle size of the upper-layer screen is larger than the particle size of the lower-layer screen. By means of the double-layer independent shock excitation screening device used for shield construction muck treatment, the upper-layer box body and the lower-layer box body are in a series connection relationship, muck is subjected to two stages of screening treatment through the upper-layer screen and the lower-layer screen, and the overall treatment efficiency and treatment effect of the screening device can be effectively improved; and in addition, the upper-layer box body and the lower-layer box bodyare independent from each other in structure and function, the same vibration characteristic or different vibration characteristics can be used for different types of muck for vibration screening, thescreening device can achieve muck screening with different characteristics, and the overall treatment efficiency of the screening device is further improved.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling slag treatment, in particular to a double-layer independent vibration screening device for shield construction slag treatment. Background technique [0002] At present, the direct transport method is mostly adopted for the disposal of the muck generated in shield tunneling construction, but directly transporting the muck to landfill will pollute the environment, and a large amount of available resources in the muck will be wasted, so some construction sites use The method of vibrating sieving is adopted to classify and treat the muck. [0003] In the prior art, the muck excavated by the shield machine will be transported to the vibrating screening equipment in different ways. Since the strata that the shield machine passes through are often complex and the properties of sand and gravel are unstable, different types of sand with different particle sizes Stone, it is necessary to screen th...
