Abstract

The invention relates to a tower-shaped staggered laminated screen, which belongs to the technical field of fine fraction wet screening, and comprises a fixed frame, a screening device, an excitation device, a feed port, an oversize product chute and a discharge device, the fixed rack is connected to a foundation through ROSTA springs; the screening device comprises a movable rack connected with the fixed rack through ROSTA springs and four layers of screening frames obliquely arranged on the movable rack in a staggered mode. The excitation device comprises two vibration motors connected to the movable rack. The discharging device comprises an oversize product discharging port, an undersize product collecting tank and an undersize product discharging port. According to the tower-shaped staggered design, the occupied area is compressed, rapid spreading of the first-section screening and fine screening of the second-section screening are achieved, and a new equal-thickness screening implementation mode is provided. According to the other implementation mode of the structure, a single plastid is changed into independent multiple plastids, the reliability is enhanced, the vibration direction angle is set more flexibly, and the included angle and the phase of the vibration motor can be adjusted to eliminate the dynamic load in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of fine wet screening, in particular to a tower-shaped staggered laminated screen. Background technique [0002] In the fields of metallurgy, mining, chemical industry, building materials, etc., fine screening plays a very important role. With the development of the industry and the improvement of production capacity, there are higher requirements for the processing capacity and screening efficiency of screening equipment. Due to the difficulty of fine-grained screening, sufficient screen surface length is required to ensure screening efficiency. However, the original plant floor area limits the space of screening equipment, and the processing capacity cannot be improved by simply increasing the number of equipment. The single-layer screen structure is difficult to meet the needs of production. Therefore, the screen surface is arranged in layers, and the multi-layer screen that doubles the processing capaci...
