Description

Technical Field

[0001] The utility model relates to the technical field of rotary drums, in particular to a combined rotary drum. Background Art

[0002] The rotary drum is an engineering equipment, also called a rotating drum or a rotary drum. The rotary drum is widely used in the field of material drying. It is a cylindrical device, usually made of metal, used for rotating operation in industrial production. The principle is to blow hot air into it, and the hot air exchanges heat with the material picked up by the scoop plate in the rotary drum, thereby taking away the moisture in the material to achieve the effect of drying the material. How the material can effectively exchange heat with the hot air determines the thermal efficiency of the equipment, allowing the same size of equipment to process more materials and improve the equipment capacity.

[0003] However, in the existing conventional rotary drum, the lifting plates are all lifting structures of uniform form and angle. However, as the hot air flows in the kiln body, it will produce certain temperature changes due to heat exchange with the materials and the drum itself. When the existing equipment finds that the efficiency of the rotary drum is insufficient, it blindly increases the equipment specifications to increase production capacity, resulting in energy waste and high production costs. Utility Model Content

[0004] The purpose of the utility model is to provide a rationally designed combined rotary cylinder to solve the defects and shortcomings of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: it comprises a rotary drum, the two ends of the rotary drum are respectively an air inlet and an air outlet, the inside of the rotary drum is divided into zone A, zone B and zone C along the direction from the air outlet to the air inlet, and a plurality of copying plates are evenly installed in zone A, zone B and zone C.

[0006] Preferably, a plurality of lifting plates 1 are evenly arranged along the inner wall of the rotating drum in the A zone of the rotating drum, and the inner angle of the lifting plates 1 is 120°.

[0007] Preferably, a plurality of copying boards 2 and copying boards 1 are evenly arranged along the inner wall of the rotary drum in zone B of the rotary drum, and the plurality of copying boards 2 and copying boards 1 are alternately arranged, and the inner side angle of the copying board 2 is 105°.

[0008] Preferably, a plurality of copying boards 2 and copying boards 3 are evenly arranged along the inner wall of the rotary drum in zone C of the rotary drum, the plurality of copying boards 2 and copying boards 3 are alternately arranged, and the inner side angle of the copying board 3 is 90°.

[0009] Preferably, the feeding direction of the rotary drum is from the air outlet to the air inlet.

[0010] After adopting the above structure, the beneficial effects of the utility model are:

[0011] In this device, a combined rotary drum lifting plate is used to realize dynamic drying in different temperature ranges. After the hot air enters the rotary drum, the hot air temperature gradually decreases as it gradually exchanges heat with the material. In the C zone near the air inlet, a lifting plate 3 is set to increase the lifting height of the material to improve the heat exchange efficiency. In the A zone far away from the air inlet, a lifting plate 1 is set to reduce the lifting height of the material, thereby improving the heat exchange efficiency, saving energy, and increasing production capacity. At the same time, it reduces air pollution and the difficulty of subsequent air pollution treatment. At the same time, compared with conventional lifting plates, there is no increase in cost.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 As shown, it comprises a rotary drum 1, with an air inlet 5 and an air outlet 6 at both ends thereof respectively. The interior of the rotary drum 1 is divided into zone A, zone B and zone C along the direction from the air outlet 6 to the air inlet 5, and a plurality of copying plates are evenly installed in the zones A, B and C.

[0020] See also Figure 1-Figure 2 As shown, a plurality of copying plates 2 are evenly arranged along the inner wall of the rotary drum 1 in the A zone of the rotary drum 1, and the inner side angle of the copying plates 2 is 120°.

[0021] See also Figure 1-Figure 3As shown, a plurality of copying boards 2 3 and copying boards 1 2 are evenly arranged along the inner wall of the rotary drum 1 in the B zone of the rotary drum 1, and the plurality of copying boards 2 3 and copying boards 1 2 are alternately arranged, and the inner side angle of the copying boards 2 3 is 105°.

[0022] See also Figure 1-Figure 4 As shown, a plurality of copying boards 2 3 and copying boards 3 4 are evenly arranged along the inner wall of the rotary drum 1 in the C zone of the rotary drum 1, and the plurality of copying boards 2 3 and copying boards 3 4 are alternately arranged, and the inner side angle of the copying boards 3 4 is 90°.

[0023] See also Figure 1-Figure 4 As shown, the feeding direction of the rotary drum 1 is from the air outlet 6 to the air inlet 5.

[0024] The principle and use process of this utility model:

[0025] In the present device, a copy board 2 with an angle of 120° is arranged in zone A. Since the angle inside the copy board is relatively large, the material will fall down when the height lifted by the copy board is relatively low, and the hot air inlet is at the air inlet 5. When the airflow reaches zone A, the temperature is relatively low, and it is not meaningful to copy the material high. There is no need for a larger heat exchange area for heat exchange, and this place is close to the air outlet 6. If the material is copied too high, the airflow will carry away a large amount of dust, which is not conducive to the subsequent dust removal of the exhaust gas; a copy board 2 with an angle of 120° and a copy board 3 with an angle of 105° are arranged in zone B, so as to appropriately increase the copy board angle of zone B and increase the heat exchange area of ​​this zone. The temperature of the hot air passing through zone B is moderate, so as to reasonably utilize the combined structure of copy board 2 and copy board 3; similarly, a copy board 3 with an angle of 105° and a copy board 4 with an angle of 90° are arranged in zone C to increase the movement height of the material, thereby improving the heat exchange efficiency, and there is no need to consider the dust problem caused by copying the material too high in this zone.

[0026] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or within the equivalent forms of such scope and boundaries.
