Description

Technical Field

[0001] The utility model relates to the technical field of grain drying equipment, in particular to a novel continuous drying tower. Background Art

[0002] Grain drying tower is an important grain drying equipment, which is used to dry high-moisture grain to make the grain reach a safe moisture content. Grain drying towers in the existing technology mostly adopt a single-process drying mode, that is, the grain is dried in the process of wet grain descending from the upper grain storage section of the drying tower to the bottom grain discharge section, so that the grain discharged from the bottom grain discharge section reaches a safe moisture content. The drying tower adopts this single-process drying mode. A higher height is required to ensure that the grain has enough travel in the drying tower to contact the hot air. However, the drying tower with a single-process drying mode adopts the method of hot air entering from one side and flowing out from the other side. The air inlet hood is located outside the tower body, resulting in a large heat loss. Moreover, the drying tower with this structure has only one heating and drying section, and the hot air flow rate is small. Therefore, it cannot meet the drying requirements for high-moisture grain. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a new continuous drying tower, which adopts a double heating design through a built-in heating furnace and a fan unit. It can increase the drying area in the drying tower and effectively improve the drying efficiency. At the same time, the second heating reheats the hot air that has been dried once, which can effectively reduce energy waste.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] A new type of continuous drying tower includes a main body for loading grain, and shells for hot air flow are provided on both sides of the main body.

The heat exchange tubes are connected to the two shells. Partitions are provided in the same horizontal plane between the first drying tube group and the second drying tube group and between the first heat exchange tube group and the second heat exchange tube group in the two shells to block the vertical connection of the corresponding shells. An air outlet and an air inlet are respectively provided at the upper and lower ends of a certain shell on one side of the main body, and heating equipment matching the first heat exchange tube group and the second drying tube group are respectively installed in the two shells.

[0006] Preferably, the heating device includes a corresponding heating furnace and a fan unit, and the heating furnace and the fan unit are respectively installed in the two shells.

[0007] Preferably, an auxiliary inlet is provided on the outer shell on one side of the heating furnace.

[0008] Preferably, the two shells are respectively configured as a left shell and a right shell, the air inlet and the air outlet are respectively located at the upper and lower ends of the left shell, and a partition plate is provided between the two partitions of the right shell.

[0010] Preferably, a heating furnace matching the first drying tube group is installed on the first baffle above the air inlet in the same shell, and an air intake group matching the air inlet is installed on the first baffle above the air inlet in different shells.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. In the present invention, by adding outer shells on both sides of the main body for installing the fan unit and the heating furnace, the built-in design of the heating furnace and the fan unit can not only improve the overall aesthetics, but also prevent the heating furnace and the fan unit from being damaged by being exposed to the air for a long time. At the same time, the residual heat generated by the heating furnace during the heating process is used to maintain the temperature of the grain drying position in the main body;

[0013] 2. In this utility model, the outer shell and the baffle cooperate to realize the alternating upward flow of air in the two outer shells, which can effectively increase the retention time of hot air in the main body and is conducive to improving the drying effect;

[0014] 3. In the present invention, the first heat exchange tube group cooperates with the second heat exchange tube group, and the grain passing through the second drying tube group exchanges heat with the air entering the shell through the first heat exchange tube group and the second heat exchange tube group, which can not only increase the temperature of the air, shorten the heating time of the heating furnace, and reduce energy consumption, but also reduce the temperature of the grain after drying, so that the grain can alternate between high and low temperatures during the cyclic drying process, which can promote rapid water loss of the grain and improve the drying effect of the grain;

[0015] 4. In the present invention, the first drying tube group and the second drying tube group are coordinated to effectively increase the area of ​​the drying area in the drying tower and effectively improve the drying efficiency.
