Spiral tower-type screening machine

Abstract

The invention discloses a spiral tower-type screening machine which comprises a bracket, an inner screen body and an outer screen body. The outer screen body is rotationally mounted on the bracket. A driving mechanism for driving the outer screen body to rotate on the bracket is arranged on the bracket. A plurality of elastic damping devices are respectively connected between the inner screen body and the outer screen body. A column body is arranged in the inner screen body. One or more spiral screen stencils are fixedly connected between the inner screen body and the column body. Guide chutes are respectively and fixedly connected to the bottom ends of the spiral screen stencils. A fine aggregate bin and one or more coarse aggregate bins are respectively mounted on the bracket. The coarse aggregate bins are correspondingly matched with the guide chutes in the bottom ends of the spiral screen stencils. A vibration device is mounted on the inner screen body or the column body. The spiral tower-type screening machine is simple and concise in structure, material screening is thorough and clear, the screening quantity is large, wear of the screen stencils is little, energy consumption is low, noise is small, the phenomenon that the materials block screen holes is prevented, the noise and dust sealing effect is good, the cost is reduced, the environment is improved, time and labor are saved in mounting and processing, maintaining is simple, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of screening devices for solid materials, in particular to a spiral tower screening machine. Background technique [0002] With the rapid development of my country's economy, the scale of infrastructure construction is huge. The demand for building materials will be staggering. China is also a country with a large demand for mineral products. The mineral product processing market has broad prospects. At present, in China and even abroad, the screening of mineral products has always been dominated by box-type vibrating screens. Box-type vibrating screens have always been known for their small processing capacity, high energy consumption, high noise, and serious dust. Often a 1000t / h The combined construction aggregate crushing and screening line needs to install 6-8 box-type vibrating screens, which brings a series of problems such as large investment, complex system, difficult control of environmental pollution, an...

At present, in China and even abroad, the screening of mineral products has always been dominated by box-type vibrating screens. Box-type vibrating screens have always been known for their small processing capacity, high energy consumption, high noise, and serious dust. Often a 1000t / h The building aggregate crushing and screening line needs to install 6-8 box-type vibrating screens, which brings a series of problems such as large investment, complex system, difficult control of environmental pollution, and high energy consumption.
