Description

Technical Field

[0001] This utility model belongs to the field of dryers, specifically relating to an adjustable air distribution structure for a box-type fluidized bed dryer. Background Technology

[0002] Fluidized bed drying technology is an effective method widely used for drying powdery and granular materials. It achieves rapid and efficient drying in a short time through the principle of boiling. However, traditional fluidized bed dryers often use a fixed air volume design, which makes it difficult to meet the drying needs of different materials, resulting in uneven drying effects and unstable product quality. At the same time, many drying processes involve materials that are explosive, flammable, or otherwise have special temperature sensitivities. Fixed air volume designs cannot effectively deal with these situations, posing safety hazards or affecting the drying quality of materials. Therefore, it is necessary to design a box-type fluidized bed dryer with an adjustable air distribution structure to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The box-type fluidized bed dryer has an adjustable air distribution structure, including a ventilation duct. A rotating shaft is rotatably connected inside the ventilation duct, and a flap is fixedly connected to the rotating shaft. One end of the rotating shaft is provided with an adjustment component that drives the rotating shaft to rotate. The adjustment component includes an adjustment handle fixedly connected to the rotating shaft. A limit plate is fixedly fixed on the adjustment handle, and a limit groove is provided on the limit plate. A locking component is inserted into the limit groove.

[0006] As a further improvement to this utility model, a stationary ring is fitted at the end of the rotating shaft away from the adjusting component, the stationary ring is fixed to the outer wall of the ventilation cylinder, and the rotating shaft is rotatably connected to the stationary ring.

[0007] As a further improvement to this utility model, the outer wall of the ventilation cylinder is also provided with a sealing ring, and the rotating shaft is inserted into the sealing ring and rotatably connected to the sealing ring.

[0008] As a further improvement to this utility model, the limiting plate is generally arc-shaped.

[0009] As a further improvement to this utility model, the limiting groove is generally arc-shaped.

[0010] As a further improvement to this utility model, the locking assembly includes a positioning post fixedly connected to the outer wall of the ventilation duct, and a ring-shaped handle is inserted into the positioning post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a flap inside a ventilation duct, which is then rotated by an adjusting component to flip the flap, thereby changing the airflow inside the ventilation duct. This allows for precise control of the airflow during the drying process, effectively improving drying efficiency and product quality.

[0013] This invention effectively assists the adjustment component in making precise adjustments and fixing it after adjustment by setting a locking component, thereby improving the drying efficiency of the product. Attached Figure Description

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention provides the following embodiments:

[0021] The box-type fluidized bed dryer has an adjustable air distribution structure, including a ventilation duct 1. A rotating shaft 2 is rotatably connected inside the ventilation duct 1, and a flap 3 is fixedly connected to the rotating shaft 2. One end of the rotating shaft 2 is provided with an adjustment component 4 that drives the rotating shaft 2 to rotate. The adjustment component 4 includes an adjustment handle 41 fixedly connected to the rotating shaft 2. A limit plate 42 is fixedly fixed to the adjustment handle 41, and a limit groove 421 is provided on the limit plate 42. A locking component 43 is inserted into the limit groove 421. This utility model, by setting a flap 3 inside the ventilation duct 1, and then driving the rotating shaft 2 to rotate through the adjustment component 4, thereby causing the flap 3 to flip, changes the air intake volume inside the ventilation duct 1. This allows for precise control of the airflow state during the drying process, effectively improving drying efficiency and product quality.

[0022] A stationary ring 5 is fitted onto the end of the rotating shaft 2 away from the adjusting component 4. The stationary ring 5 is fixed to the outer wall of the ventilation cylinder 1. The rotating shaft 2 is rotatably connected to the stationary ring 5. The stationary ring 5 helps to stabilize the rotation of the rotating shaft 2.

[0023] The outer wall of the ventilation duct 1 is also provided with a sealing ring 6. The rotating shaft 2 is inserted into the sealing ring 6 and rotatably connected to the sealing ring 6. The sealing ring 6 helps to seal the ventilation duct 1, prevents internal air leakage and thus reduces the drying efficiency of the material.

[0024] The limiting plate 42 is generally arc-shaped, and the limiting groove 421 is generally arc-shaped. The shapes of the limiting plate 42 and the limiting groove 421 fit together. The locking assembly 43 includes a positioning post 44 that is fixedly connected to the outer wall of the ventilation duct 1. A ring-shaped handle 45 is inserted into the positioning post 44. The adjusting handle 41 drives the rotating shaft 2 to rotate, and at the same time, the limiting plate 42 starts to rotate. At this time, the limiting groove 421 rotates along the positioning post 44 to prevent the adjusting handle 41 from changing position during rotation.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
