Embodiment 1

[0051] Referring to FIG. 1, the circulation device for a dryer proposed in the first embodiment includes a grain storage mechanism 1, nine hygrometers 2, a drying mechanism 3, and three first valves 4 ( figure 1 (not shown in the figure) and the lifting mechanism 5.

[0052] The grain storage mechanism 1 has a rectangular parallelepiped structure. The grain storage mechanism 1 is provided with three grain storage cavities 11. The three grain storage cavities 11 are arranged in sequence along the horizontal direction. The top of the grain storage cavity 11 is the feed inlet of the grain storage cavity 11. The bottom of the grain storage cavity 11 is the discharge port of the grain storage cavity 11 ; the grain to be dried needs to be stored in the grain storage cavity 11 first.

[0053] The hygrometer 2 is used to monitor the humidity of the grain in the grain storage cavity 11. The nine hygrometers 2 are respectively installed in the three grain storage cavity 11. Three hygrom...

Embodiment 2

[0061] Image 6 A partial schematic diagram of the circulation device in the second embodiment is shown. The circulation device in the second embodiment, which is the same as the first embodiment, also includes a grain storage mechanism 1, nine hygrometers 2, a drying mechanism 3, and three first The valve 4 and the lifting mechanism 5, as well as the grain storage mechanism 1, the nine hygrometers 2, the drying mechanism 3 and the three first valves 4 have the same structure and arrangement as the first embodiment. The difference is that the hose 53 is not provided at the top of the second pipe section 52 in the second elevator, and the structure of the second material guide barrel 56 is different from that of the first material guide barrel 54 . The second guide cylinder 56 in the second embodiment is directly connected to the second end of the second pipe section 52, and the discharge port of the second guide cylinder is located above the three grain storage cavities 11, an...

Embodiment 3

[0065] Figure 8A partial schematic diagram of the circulation device in the third embodiment is shown. The circulation device in the third embodiment, which is the same as the second embodiment, also includes a grain storage mechanism 1, nine hygrometers 2, a drying mechanism 3, three first The structure and arrangement of the valve 4, the second valve 6 and the lifting mechanism 5, and the grain storage mechanism 1, the nine hygrometers 2, the drying mechanism 3, the three first valves 4 and the three second valves 6 are the embodiments Two are the same. The difference is that the heights of the feeding ports of the three grain storage cavities 11 are sequentially decreased, and when all the second valves 6 are closed, all the first cover plates 61 and the second cover plates 62 are located in the same inclined plane, and the second material guide The discharge end of the barrel 56 is located just above the grain storage cavity 11 with the highest height of the feed opening...

Abstract

The invention provides a circulation device for a dryer. The grain storage mechanism is provided with n grain storage chambers; m hygrometers are respectively installed in the n grain storage chambers, m≥n; the drying mechanism is connected with the grain storage mechanism, The drying mechanism is provided with a drying cavity, and n first valves are respectively installed between the n grain storage cavities and the drying cavity; the feeding end of the lifting mechanism is communicated with the discharge port of the drying cavity, and the discharge of the lifting mechanism The end is connected with the grain storage mechanism, and the discharge end of the lifting mechanism can transport materials to one or more grain storage cavities; the circulation device for a dryer of the present invention can store grains with different moisture contents in different grain storage cavities respectively. Inside, the grain with the highest water content is dried to the grain with the second lowest water content in order to ensure that the water content of the grain in the grain storage cavity can reach the same level as the grain with the original minimum water content, and finally all the grain in the grain storage cavity is dried. Dry at the same time. The moisture content of the final dried grains is the same, and there is no need to load and unload in batches, so the operation is simpler.

Description

technical field [0001] The invention belongs to the field of drying equipment, and particularly relates to a circulation device for a dryer. Background technique [0002] Grain processing plants and grain storage enterprises purchase grains from farmers that need to be dried for long-term storage. Due to the different moisture content of the purchased grains, the grains with different moisture contents are mixed together and dried. During the drying process, the original moisture content After drying, the moisture content of the lower grain has been lower than the predetermined value, while the grain with the original higher moisture content has not reached the predetermined value and needs to continue to be dried, which adds unnecessary drying to the grain with lower moisture content. The drying time is long, and the grain with low moisture content is far below the predetermined value after drying, and the grain with high moisture content just reaches the predetermined valu...
