Wind pressure type three-cabin wind separator

Abstract

The invention relates to a wind pressure type three-cabin wind separator composed of two separating cabins and one blanking cabin serially connected and provided with integrated dynamic wind pressure, is especially applicable to wind separation for easily broken materials, and belongs to wind separation equipment. The upper side wall of the first separating cabin is communicated with the upper side wall of the second separating cabin, and the upper side wall of the second separating cabin is communicated with the upper side wall of the blanking cabin to form a structure with the three cabins serially communicated, and a transferring mesh belt is arranged on a channel port of the inside walls, where the three cabins are serially communicated, of the two separating cabins and the one blanking cabin. The transferring mesh belt is horizontally arranged, a wind curtain for isolating the two cabins is arranged on a channel port where the first and second separating cabins are communicated, and another wind curtain for isolating the two cabins is further arranged on a channel port where the second separating cabin and the blanking cabin are communicated.

Description

Technical field [0001] The invention relates to an air pressure type three-storey air separator, in particular to an air separator with integrated dynamic air pressure, which uses two separation bins and a blanking bin to be connected in series, and is particularly suitable for processing easily broken materials. Wind sorting belongs to wind sorting equipment. Background technique [0002] The principle of airflow separation: flotation of a certain material in the airflow, set a certain airflow speed, so that the lighter part of the material whose suspended velocity is lower than the set airflow velocity moves upward, and the suspended velocity of the material is higher than the set airflow velocity The heavier part moves downwards, so that the material is separated into the heavier and lighter parts in the airflow. This principle is widely used in various industries. For example, CN 201454852 U discloses a device for sorting heavier and better seeds by wind power. [0003] CN 29...

AI Technical Summary

Problems solved by technology

[0006] The lighter and effective materials separated by the wind force of the above equipment must be separated by pipeline transportation and air material separation device, and the materials will be separated during the transportation and separation process. Reduced moisture and intense mechanical friction will result in smaller material sizes and a large amount of fines, reducing the use value of materials

At the same time, the above devices can only complete the sorting function, and all of them need a feeder to complete the separation of gas and materials. The corresponding equipment is complex and energy-consuming.

[0007] In addition, wind separation equipment is widely used in both threshing and redrying and silk making process, but the blanking device used is a cross door type blanking device, and the shredded tobacco leaves are inevitably squeezed when passing through the blanking device resulting in fragmentation

If the material is in contact with the wind for a long time, the water will lose a lot, and it will easily break when it collides with the pipeline.
