[0002] The selection and configuration of grain dryers are based on the relative movement direction of grain and airflow. Dryers can be divided into cross-flow, mixed-flow, co-flow, counter-flow, and co-counter-flow, mixed-counter-flow, and co-mixed-flow types. In order to complete the drying operation well, dryers must be equipped with some auxiliary equipment. Continuous dryers should be equipped with upper and lower material level gauges in the grain storage section, full-load material level gauges in the temporary storage bins in the process, and automatic stop and blockage alarm devices for the elevators.
[0003] Existing technologies for grain drying towers still have certain shortcomings in their use. In traditional grain drying towers, the grain is usually screened and filtered before drying. However, some dust will still remain in the grain after screening. Dust mixed in with the grain will affect the quality of grain drying and reduce the efficiency of grain drying.

A dust removal channel 8 is provided on the outside of the grain dust collector 4, and a dust suction port 9 is provided inside the grain drying tower 1 at a position aligned with the dust removal channel 8. The feed hopper 3 is used to transport the dust-removed grain to the elevator 2, and the elevator 2 is used to transport the grain to the grain drying tower 1. The grain dust collector 4 is used to remove dust from the grain. The grain dust collector cylinder 10 is used to filter and remove dust from the grain. The equalization plate 11 is used to spread the grain inside. The centralized slowing trough 5 is used to change the flow rate of the grain conveying so that the grain is conveyed downward at a uniform speed. The dust collection box 16 is used to store the dust. The fan 18 is used to suck the dust downward and remove it. The dust removal channel 8 is used to increase the installation position of the dust suction port 9, and the dust suction port 9 is used to suck in and remove the dust.
[0022] The material distribution plate 11 has multiple support rods 25 inside, and the material distribution plate 11 is designed with an inclined structure. The support rods 25 are used to divide the interior of the material distribution plate 11 into multiple gaps.
[0023] The grain dust collector 10 is equipped with a filter screen 24 on its exterior, and the cross-section of the grain dust collector 10 is a square structure. The filter screen 24 is used to filter dust and grain. The upper and lower ends of the grain dust collector 10 are welded to the upper support plate 7 and the lower support plate 12, and the upper support plate 7 and the lower support plate 12 are both circular in shape.

[0025] Working principle: During use, the sieved grain is poured into the feed inlet 6, allowing it to enter the centralized buffer trough 5. The centralized buffer trough 5 reduces the downward flow of the grain, allowing it to be conveyed downwards at a uniform speed into the grain dust removal cylinder 10. The uniform distribution plate 11 increases the resistance of the grain, causing it to be evenly distributed downwards. The fan 18 increases the internal suction, drawing dust from the grain into the dust removal channel 8 through the dust suction port 9. The dust is then conveyed to the dust collection box 16 through the second connecting pipe 17, where it is stored. The clean grain is then conveyed to the discharge port 15 through the first connecting pipe 13, and from the discharge port 15, it is conveyed to the feed hopper 3. Finally, the elevator 2 conveys the clean grain to the grain drying tower 1 for drying.
