Description

Technical Field

[0001] The utility model relates to the technical field of hollow blades for dryers, in particular to a blade for dryers. Background Art

[0002] The hollow blade dryer is a horizontal agitator dryer that uses a heat medium as a medium and paddles to stir the material to transfer heat. With the rapid development of my country's economy and industrialization, hollow blade dryers are widely used in industries that require drying processes, such as petrochemicals, environmental protection, feed, and food.

[0003] However, many hollow paddle dryers on the market currently use a structural design in which one side of the blade is heated and the other side is drained. This can easily cause the condensed water discharged from the blade to flow back into the blade, reducing the steam heating efficiency and thus resulting in low drying efficiency of the dryer.

[0004] Therefore, it is necessary to design a dryer blade that can prevent condensed water from flowing back into the hollow blade. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-2 The utility model provides a technical solution: a dryer blade, including a hollow blade 2, a blade shaft 3, and a bolt 9. The hollow blade 2 is welded and fixed to the blade shaft 3. A scraper 1 is provided at the end of the hollow blade 2, and the scraper 1 is fixed to the hollow blade 2 by bolts 9.

[0022] A baffle 1 5 is fixed to the top of the inner side of the hollow blade 2, and a guide plate 6 is fixed to the bottom of the hollow blade 2. Baffle 1 5 is located above the guide plate 6. Baffle 2 7 is fixed to the inner side of the guide plate 6. Baffles 2 7 are arranged in a cross-shaped pattern and fixed to the inner side of the guide plate 6. The interior of the blade shaft 3 is an inner cavity 10, and the guide plate 6 extends through the blade shaft 3 into the inner cavity 10.

[0023] Each set of hollow blades 2 is internally provided with two sets of baffles 5 and two sets of guide plates 6, which are symmetrically distributed and can cope with rotations in different directions, thus enhancing versatility.

[0024] Four groups of steam pipes 4 are arranged inside the blade shaft 3 , and a steam shaft 8 is arranged inside the inner cavity 10 . The steam pipes 4 pass through the steam shaft 8 and the blade shaft 3 , so that hot steam can enter the hollow blade 2 through the steam pipes 4 .

[0025] Every two groups of steam pipes 4 are distributed inside a group of hollow blades 2, and the two groups of steam pipes 4 are distributed on both sides of the guide plate 6, which enhances the heating efficiency of the hot steam and avoids the problem of uneven heating on the left and right sides of the hollow blades 2.

[0026] The baffles 7 are cross-distributed and fixed on the inner side of the guide plate 6 , forming a 45-degree angle with the vertical portion of the guide plate 6 , so as to prevent the condensed water from flowing back into the hollow blades 2 .

[0027] Working principle:

[0028] When the equipment is running, hot steam enters the hollow blade 2 through the steam pipe 4 for heating. Because there are two steam pipes 4 inside each hollow blade 2 to simultaneously transport hot steam, the inside of the hollow blade 2 is heated evenly and with high heating efficiency.

[0029] As steam pipe 4 delivers hot steam, condensate forms inside hollow paddle 2. As paddle shaft 3 and hollow paddle 2 rotate, the condensate, under the influence of gravity, flows through baffle 1 5 and guide plate 6, redirecting its flow. After passing through baffle 2 7, it enters inner cavity 10 and is discharged. The symmetrical design of baffle 1 5 and guide plate 6 accommodates both clockwise and counterclockwise rotation, enhancing versatility.

[0030] After entering the inner cavity 10, the condensed water may flow back into the hollow blade 2 as the equipment rotates. Because the baffle 2 7 and the guide plate 6 are at a certain angle, it prevents the condensed water from flowing back and improves the thermal efficiency.

[0031] When the inner wall of the mixer cabinet needs to be cleaned, the scraper 1 can be fixed to the end of the hollow blade 2 using bolts 9. This allows the scraper 1 to rotate with the equipment while also cleaning the material adhering to the inner wall of the cabinet. Bolts 9 not only secure the scraper 1 but also facilitate its removal. The bolt hole at the end of the hollow blade 2 must not exceed the thickness of the side wall of the hollow blade 2 itself. The scraper 1 is required to have a runway-shaped hole. When the bolt 9 passes through, the distance from the scraper 1 to the inner wall of the cabinet can be adjusted according to the actual size, enhancing flexibility and versatility on equipment of different sizes.
