Closed S-shaped grain conveying dust removing device

Abstract

The invention discloses a closed S-shaped grain conveying dust removing device and relates to the field of grain processing. The device comprises a first dust removing bin, a second dust removing binand a third dust removing bin which form an S-shaped sealed cavity; conveyors are fixedly mounted at the bottoms of the first dust removing bin, the second dust removing bin and the third dust-removing bin correspondingly; the three sets of conveyors are staggered left and right; a plurality of cam rollers are mounted in the conveyors; a collecting bucket is fixedly mounted at the bottom of the third dust removing bin; a plurality of guide pipes are fixedly connected with the tops of the two sides of the collecting bucket; the side walls of the inner sides of the guide pipes are fixedly connected with three sets of dust removing pipes; the three sets of dust removing pipes penetrate through the two sides of the first dust removing bin, the two sides of the second dust removing bin and thetwo sides of the third dust removing bin correspondingly and extend into an inner cavity of the first dust removing bin, an inner cavity of the second dust removing bin and an inner cavity of the third dust removing bin correspondingly; and negative pressure fans are fixedly mounted in inner cavities of the dust removing pipes. Impurities in grain are separated after the grain is raised, the dustremoval effect is good, and the efficiency is high.

Description

[0001] Technical field: [0002] The invention relates to the field of grain processing, in particular to a closed S-shaped grain conveying dust removal device. [0003] Background technique: [0004] Before storing grains such as rice and wheat, it is necessary to dry the grains. The usual method is to expose the grains to the sun. However, this drying method is inefficient and is easily affected by the weather and geographical environment. Many farmers expose the grains to the sun. There will also be safety hazards on the roadside, and now grain dryers are usually used instead of traditional grain drying methods. [0005] The grain dryer is mainly used for drying rice and wheat, and it can also be used for drying rapeseed and other crops after a little improvement. Grain dryer is composed of main components such as coal furnace, motor, axial flow fan and stacking rack. When the grain dryer is working, the motor drives the impeller of the axial flow fan to rotate at a high s...

AI Technical Summary

Problems solved by technology

The existing grain dryer does not have the function of dust removal and impurity removal. Although it has been dried for many times, the dust and impurities in it still remain in it and cannot be discharged. The grain itself will carry shells, low-quality grain and dust, etc. As the moisture content of the grain decreases, these sundries and dust will be suspended inside the grain dryer. Due to the high pressure of the hot air inside the machine, the sundries and dust will fly around
