Technical Field

The invention relates to the technical field of impurity removing equipment, in particular to equipment for removing corncobs and light floating impurities under positive and negative pressure.

Background

The existing grain screening machine generally adopts a positive pressure technology, which is generally called as a specific gravity screen, and the selected materials are distinguished according to different weights (the specific gravity and the volume weight) of the selected materials. In the aspect of grain screening, the specific gravity sieve is widely applied (the yield is generally 20 tons-30 tons per hour), but with the development of times, the screening equipment has higher requirements on the yield and the precision, and the maximum yield of the existing screening equipment can only reach 60 tons per hour, and the precision is not satisfactory.

The working principle of the specific gravity sieve is as follows: the selected materials are called as a sieve bed through a vibrating sieve surface with a certain inclination angle, the materials (various grain crops) uniformly move to one high side along with the vibration of the sieve bed, an air blower blows air in the lower part of the sieve bed, the materials on the sieve bed are layered under the action of the air flow of the air blower, the heavier materials move upwards along the vibration direction under the action of the vibration of the sieve bed (called as upstream by the inventor), the lighter materials (such as corncobs, bran, bean skins, mildewed particles and the like) float on the upper layer and cannot be contacted with the sieve bed, and the sieve bed floats downwards due to the inclination angle and moves towards the lower side, so that the separation effect is achieved.

The working efficiency of the existing grain screening machine reaches the bottleneck, the fundamental reason is still determined by the working principle of the existing grain screening machine, the finished product material is in the whole layering process, the air flow from the air blower to the bottom and the top acts on the material, and finally the finished product material and the light impurity waste material are layered and further separated, the three stress directions are mutually constrained, so that the upward speed of the finished product material is reduced, and the discharging speed of the finished product material is influenced, therefore, the form is called as 'upstream', and the existing grain screening machine has the problem that the existing grain screening machine can only play a suspension role compared with the light material of the grain crop due to the wind power generated by the air blower, but can not play a suspension role on the hard impurities (stone, soil, glass, iron and the like) with large specific gravity (large weight), and therefore, the existing screening machine can not remove the hard impurities (with the same volume).
