Problems solved by technology

Due to the short development time, low technical content and poor manufacturing level of some domestic enterprises, banana screens have not been improved in time, it is difficult to finalize and promote, and the products cannot meet higher requirements for use. Therefore, the design of new coal preparation plants and the transformation of old coal preparation plants Most of them use imported equipment with better quality

Abstract

The invention provides a linear double-layer banana screen for mineral screening. A lifting beam is arranged on a lifting beam installation piece. A side face installation piece is arranged at one end of the lifting beam installation piece. A back installation plate is arranged at the other end of the lifting beam installation piece. Lower cross beams are arranged at the lower end of the side face installation piece and the lower end of the back installation plate. Upper cross beams are arranged in the middle of the side face installation piece and the middle of the back installation plate. A vibration excitation beam is arranged in the middle of the lifting beam installation piece through a vibration excitation flange. A left screening vibration exciter and a right screening vibration exciter are arranged on a screen body and connected through a vibration exciter connection shaft. The vibration excitation beam is arranged below the left screening vibration exciter and the right screening vibration exciter. One end of a driving connection shaft is connected with the vibration exciter connection shaft, and the other end of the driving connection shaft is connected with a rotary shaft of a vibration driving motor. A rotary shaft disc of the vibration driving motor is provided with a transmission device. Noise reduction and buffer devices are arranged between the adjacent upper cross beams and the lower cross beams. A screening device is arranged on a cross beam installation plate. The linear double-layer banana screen is simple in structure, long in service life and high in screening efficiency.

Description

technical field [0001] The invention relates to the technical field of mineral screening machinery, in particular to a linear double-layer banana screen for mineral screening. Background technique [0002] With the popularization of mechanization, comprehensive mechanization of coal mining can also be realized, and mechanized coal mining reduces the particle size of the mined coal, increases the amount of pulverized coal, and increases the amount of underground dust-proof water spray, which leads to an increase in the moisture content of the raw coal, thus making the wet coal When the fine particles are sieved by ordinary sieves, the sieve holes will be blocked. The emergence of the relaxation screen solves the above problems. But the sieve surface of the existing relaxation sieve is straight and inclined, the material flow speed is fast, the time for the material to stay on the sieve surface is short, and the screening efficiency is low. In recent years, with the rapid de...
