Description

Technical Field

[0001] The utility model relates to the technical field of continuous grain drying towers, and more specifically, it relates to a continuous grain drying tower. Background Technique

[0002] In the existing technology, hot air is generally used as the drying medium when drying grains in a continuous grain drying tower. This hot air is usually generated by heat exchange between a heat exchange tube and an external heating device. However, there are certain deficiencies in the existing drying tower equipment in connecting the heat exchange tube with the external heating device, which are mainly manifested in the following two aspects:

[0003] Firstly, the existing drying tower equipment lacks a convenient connection method in its structural design. Since a large amount of hot air is required for the drying tower to ensure the drying effect of grains, the connection between the heat exchange tube and the external heating device is particularly important. However, the existing equipment often does not provide a simple, fast and reliable connection method, making the connection process between the heat exchange tube and the heating device complex and time-consuming. This undoubtedly increases the installation and maintenance difficulties of the equipment, and may also affect the normal operation of the drying tower.

[0004] Secondly, the existing drying tower equipment lacks flexibility in operation. Since the working environment of the drying tower is usually relatively harsh, such as high temperature and high humidity, the operator needs to face harsh working conditions when connecting the heat exchange tube with the heating device. This not only increases the working difficulty, but also may pose a threat to the health of the operator. In addition, due to the limitation of the equipment structure, the operator may need special tools or skills during the connection process, which further reduces the operation convenience.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The design of the fixing mechanism enables the continuous grain drying tower to be stably installed on the support frame and can be conveniently connected to an external heat supply device.

[0028] In this embodiment, when it is necessary to connect the heating equipment and the heat exchange pipe 5, first insert the insertion rod into the fixed sleeve 2. Due to the arrangement of the reducing sleeve 16 on the side wall of the insertion block, the insertion block can be conveniently inserted into the fixed sleeve 2, and the insertion pipe 6 is pressed against the sealing ring 17. At this time, the clamping plate 15 is stuck on the reducing sleeve 16. Then, thread the threaded sleeve 7 onto the fixed sleeve 2. By rotating the threaded sleeve 7, the push spring 8 is pressed against the insertion pipe 6, and the follower ring 10 is driven to slide downward through the compression spring 9.

[0030] In summary, when the overall equipment is in use or operation: when it is necessary to connect the heating equipment and the heat exchange pipe 5, first insert the insertion rod into the fixed sleeve 2. Due to the arrangement of the reducing sleeve 16 on the side wall of the insertion block, the insertion block can be conveniently inserted into the fixed sleeve 2, and the insertion pipe 6 is pressed against the sealing ring 17. At this time, the clamping plate 15 is stuck on the reducing sleeve 16. Then, thread the threaded sleeve 7 onto the fixed sleeve 2. By rotating the threaded sleeve 7, the push spring 8 is pressed against the insertion pipe 6, and the follower ring 10 is driven to slide downward through the compression spring 9. Then, under the action of the pull rope 11, a plurality of sliders 12 are driven to press the shrinkage sleeve 13 to shrink and slide, and then the clamping plate 15 drives the reducing sleeve 16 to slide downward. Therefore, the insertion pipe 6 slides downward and generates corresponding pressure, and the sealing effect between the sealing ring 17 and the insertion pipe 6 is ensured through double-sided sealing.

[0031] After the connection is completed, hot water is introduced into the heat exchange pipe 5, and then the blower 18 blows air over the heat exchange pipe 5 and then through the air inlet pipe 19 into the air inlet sleeve 20 and the drying sleeve 21. Since there is grain in the drying sleeve 21, the rotation of the drying sleeve 21 can drive the grain to move forward while being dried under the action of the spiral blade 22, thus completing the continuous drying process.
