Vibration air separation device

Abstract

The invention relates to a vibration air separation device. The vibration air separation device comprises a material inlet, a powdery particle separation segment and a light and heavy material layering segment, materials enter the powdery particle separation segment from the material inlet, small particles are discharged from a powdery particle outlet after vibration screening, large particles enter the light and heavy material layering segment which is in stepped arrangement, light materials are made to be located at the upper portion of a material layer through falling head and positive pressure airflow, then a separation stage is performed, under guiding of the positive pressure airflow and negative pressure airflow, the light materials move towards the upper left direction, this moment, an adsorbing roller will generate strong negative pressure airflow to make the light materials be adsorbed on the adsorbing roller and rotate towards a light material outlet along with the adsorbingroller, when the light materials move to an air blocking ring, the negative pressure airflow disappears, the light materials fall down and are discharged from the light material outlet, because heavymaterials are large in bulk density and less affected by the airflow, the heavy materials fall directly to be discharged from a heavy material outlet, so that separation of the powdery particles, thelight materials and the heavy materials is achieved.

Description

technical field [0001] The invention relates to the technical field of material separation, in particular to a vibration air separation device. Background technique [0002] The utilization and recycling of resources starts from sorting. Commonly used sorting types include screening, gravity separation, magnetic separation, flotation, electric separation, air separation, color separation, etc. Wind separation technology, as a traditional sorting method, has been widely used in various solid waste treatment and resource recovery fields. [0003] The basic principle of winnowing is to use aerodynamic force to separate light substances and heavy substances under the action of airflow. This new patent has the functions of powder removal, light material layering, light and heavy material separation, light material automatic unloading, etc., and has good promotion and application value. [0004] Existing winnowing equipment only adopts positive pressure airflow to act on the ma...

AI Technical Summary

Problems solved by technology

There are many problems, for example: there is no powdery particle separation device, and the dust is large during the winnowing process; the separation of light and heavy substances is not complete, and the light substances in the middle and lower parts of the material layer cannot be blown out due to the upper heavy substances; there is no light substance separation device, It falls naturally by its own gravity, and it is easy to enter the fan with the negative pressure airflow; it has a single function, and can only separate light materials with large area and light weight, such as plastic bags.
