Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, and more specifically to a paddle drainage mechanism of a hollow paddle dryer. Background Art

[0002] The paddle dryer is a horizontal stirring dryer based on conduction. The main structure is a W-shaped shell with a jacket, which is equipped with a pair of hollow low-speed rotating hollow shafts. Several hollow stirring blades are welded on the shafts, and heat carriers are passed through them. Two heating surfaces heat the material at the same time. The heat carrier is usually fed into the middle of the dryer, passes through the surface of the material layer in a stirring state, and is discharged from the other side. A large amount of condensed water will appear in the process of steam heating inside, which needs to be solved by the paddle drainage mechanism of the hollow paddle dryer.

[0003] After searching in the existing public documents, the utility model patent with patent publication number CN213841706U discloses a paddle blade drainage device for a hollow paddle dryer. The prior art has the problem that the steam inlet main pipe and the hollow paddle shaft are inconvenient to connect and process with the steam inlet distribution pipe, and the condensed water is easy to flow back into the paddle blade, which reduces the steam heat exchange effect. This has become an important technical problem that needs to be solved by people in this field; the first end of the steam inlet short circuit is detachably connected to the steam delivery pipe, and the second end passes through the central axis tube and extends into the inner cavity of the paddle blade; the overflow pipe is sleeved on the outer side of the steam inlet short circuit, and its second end passes through and extends into the inner cavity of the central axis tube. A connection gap is provided between the overflow pipe and the steam inlet short circuit, which is convenient for connection and processing, preventing the condensed water from flowing back into the paddle blade, reducing the heat transfer between steam and condensed water, and thus improving the heat exchange efficiency between the paddle blade and the outside world; however, the drainage mechanism still has the following defects;

[0004] When the above-mentioned drainage mechanism drains the inside of the hollow blade dryer, the remaining water will gather at the bottom of the inner wall of the dryer. The drainage pipe is located inside the hollow blade, so it is difficult to fit the drainage pipe to the bottom of the inner wall of the dryer, and there is a larger gap. It is difficult to completely remove the water at the bottom of the inner wall of the dryer. Therefore, it is necessary to provide a hollow blade dryer blade drainage mechanism.
