Description

Technical Field

[0001] This utility model relates to the field of drying tower technology, and in particular to a low-temperature circulating grain drying tower. Background Technology

[0002] As one of the main food sources for humankind, the drying process during the storage and processing of grains is crucial. Traditional grain drying methods mainly rely on natural sun-drying or high-temperature drying equipment, but these methods suffer from low efficiency, high energy consumption, and damage to grain quality. With the development of agricultural modernization, low-temperature circulating grain drying towers, as a highly efficient and energy-saving drying device, have gradually gained widespread attention and application.

[0003] However, existing low-temperature circulating grain drying towers still have certain drawbacks. For example, the grain inside the tower is usually in a static state, which means that the grain at the bottom or in the middle of the tower cannot be heated evenly, thus affecting the overall drying effect of the grain. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature circulating grain drying tower that can repeatedly send grains back to the feeding hopper for cyclic feeding and drying, thereby ensuring that each grain of grain is repeatedly exposed to the heat source within the tower, thus improving the drying effect. The feeding hopper can be moved back and forth, allowing the grains to fall more evenly into the tower, thereby avoiding excessive feeding at one time which would affect the grain drying effect.

[0005] To achieve the above objectives, a low-temperature circulating grain drying tower is provided, comprising:

A material discharge bin 17 is fixedly connected to the outer surface of the fixed seat 19. A perforated plate 18 is fixedly connected to the inner surface of the material discharge bin 17. An outer frame plate 21 is fixedly connected to the outer surface of the material discharge bin 17. An L-shaped connecting frame 22 is fixedly connected to the front surface of the outer frame plate 21. A toothed frame 23 is fixedly connected to the end of the L-shaped connecting frame 22 away from the outer frame plate 21. A U-shaped frame 24 is fixedly connected to the front surface of the tower body 1. A second motor 25 is fixedly connected to the front surface of the U-shaped frame 24. The output end of 25 is fixedly connected to a second rotating shaft 26, and a half gear 27 is fixedly connected to the outer surface of the second rotating shaft 26. A limit seat 28 is fixedly connected to the front surface of the tower body 1. There are two slide rods 20, which are symmetrically distributed front and back.

[0030] Working principle: During operation, the heating element 5 is first heated by the temperature controller 6, and the drying temperature is controlled between 40 and 60 degrees Celsius to achieve low-temperature drying. Then, the grain to be dried is poured into the feeding hopper 17. At the same time, the second motor 25 and the first motor 13 are started. Under the action of the second motor 25, the second rotating shaft 26 drives the half gear 27 to rotate. Then, under the meshing action of the half gear 27 and the gear frame 23, the outer frame plate 21 is driven to move back and forth left and right through the L-shaped connecting frames 22 on both sides. This allows the grain poured into the feeding hopper 17 to fall evenly into the tower body 1 through the holes on the perforated plate 18 for drying, thereby improving the drying effect of the grain. After one drying process, the grain is dried. Afterward, the grains fall onto the inclined plate 9, and then along the inclined surface of the inclined plate 9 through the through hole 10 and through groove 12 into the conveying bin inside the conveying box 11. Under the action of the first motor 13, the first rotating shaft 14 drives the spiral blade 15 to rotate, thereby sending the grains that have fallen into the conveying bin to the feeding pipe 16 for further drying, and then back into the discharge bin 17 for cyclic drying. This process is repeated multiple times, which can effectively improve the drying effect of all grains. When the grains have been dried a certain number of times, simply start the electric push rod 7 to drive the L-shaped connecting plate 8 to move the inclined plate 9 outward, and at the same time open the shut-off valve 3 to discharge the dried grains through the discharge pipe 2. It is simple and convenient.
