An elastic grid tube for adjusting the movement state of the sliding granular material

Abstract

The invention relates to the technical field of particle material sorting, in particular to an elastic grid tube capable of adjusting movement states of a gliding particle material. The elastic grid tube includes a guide tube (1) and an elastic cone-shaped grid mesh (2). The elastic cone-shaped grid mesh (2) includes a plurality of grid strips, each grid strip is a cone-shaped spring (3), and multiple cone-shaped springs (3) with the same structure are circumferentially and evenly distributed along a shared axis O1O2. By adoption of the elastic grid tube, the elastic cone-shaped grid mesh (2) improves the tolerance of the size range scale of particle materials at a same level in the pre-leveling process of the equipment, reduces the level number of pre-leveling, and decreases the total configuration of leveling equipment; at the same time, multi-point supporting and guiding of the movement states in the gliding process of the particle material can be achieved, and the adjusting effect can be more reliable; and when the particle material glides out of the elastic cone-shaped grid mesh, an image formation system can capture more surface information of the particle material. The elastic grid tube capable of adjusting the movement states of the gliding particle material has the characteristics of being simple in structure, easy to clean and maintain, and low in manufacture cost.

Description

technical field [0001] The invention relates to the technical field of sorting granular materials, in particular to an elastic grid tube for adjusting the movement state of sliding granular materials. Background technique [0002] Surface information such as the color and shape of grains and other small particle materials can directly or indirectly reflect the quality of the material. Therefore, sorting and grading granular materials based on their surface information is a commonly used sorting method. [0003] The multi-channel grain color sorter widely used at present is a typical equipment for screening and sorting a large number of individual granular materials one by one based on surface information. In each channel, when the granular material slides down through the imaging system, the sensing element receives the surface information of the granular material, makes a good or bad judgment, and converts it into a sorting execution signal. Since the downward movement of...

Problems solved by technology

The inner diameter of the hard slide pipe is fixed, and the adaptability to the size change of the material is not strong

Larger-sized sliding pipes are prone to material jams during the sliding of granular materials, while smaller-sized sliding pipes are prone to radial vibrations, resulting in energy loss

If the size consistency of granular materials is excessively improved, the number of pre-classification stages and the corresponding downslide pipe grades need to be greatly increased, which increases the technical application conditions and costs.
