Abstract
Description
Technical Field
[0001] This utility model relates to the field of material drying equipment, and in particular to a fluidized bed drying device for the production of feed additive yeast selenium. Background Technology
[0002] In the feed production process, yeast selenium, as a common organic selenium source, is widely used in animal feed to improve animal immunity, promote growth and enhance antioxidant capacity. Due to its excellent bioavailability, the application of yeast selenium in animal feed is receiving increasing attention. In the process of producing yeast selenium, how to efficiently and stably dry yeast selenium is the key to ensuring its quality and production efficiency.
[0003] Traditional fluidized bed dryers consist of a dryer, an air inlet device, an air distribution plate, an exhaust device, a heat source, and a discharge device. Their working principle is to use hot air to suspend the material in a fluidized state within the bed, transfer heat to the material and evaporate moisture, and discharge the moisture through the exhaust device. Finally, the dried material is discharged. This method can effectively ensure the uniformity of material drying, reduce heat loss, and improve drying efficiency.
[0004] In traditional fluidized bed dryers, materials flow through the outlet with the airflow during the drying process. However, due to the lack of an effective screening mechanism, the particle size of the discharged material is not uniform, and particles of different sizes are discharged together, causing difficulties for subsequent processing. To address this issue, a fluidized bed dryer for the production of feed additive yeast selenium is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A motor is fixedly connected to one side of the fixed frame. A protruding rod is fixedly connected to the drive end of the motor. A rotating rod is rotatably connected to the outer wall of the protruding rod. A connecting rod is rotatably connected to one end of the rotating rod. A limit block is slidably connected to the top of the connecting rod. A fine material screening plate is fixedly connected to the top of the limit block. A medium material screening plate is fixedly connected to the top of the fine material screening plate.

Sliding rods are slidably connected to the inner walls of the two fixed plates. Springs are sleeved on the outer walls of the sliding rods. A second fixed plate is fixedly connected to the bottom of the sliding rods. An adjustment assembly is provided on the top of the base plate.
[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:
[0011] A screen is fixedly connected to the inner wall of the box, a blower is fixedly connected to the top of the bottom plate, and a heating box is installed at the drive end of the blower.
[0012] As a further description of the above technical solution:

[0022] The beneficial effects of this utility model are as follows:
[0023] (1) This utility model starts the motor, the motor drive end drives the convex rod to rotate, and then drives the rotating rod to perform reciprocating motion in the vertical direction. The reciprocating motion of the rotating rod is transmitted through the connecting rod, so that the clamp at the top of the connecting rod moves inside the limiting block and pushes the limiting block to move. The movement of the limiting block drives the fine material screening plate, the medium material screening plate and the coarse material screening plate to perform screening work. During the movement of the fine material screening plate, the plate presses down on the fixed plate and compresses the spring. When the spring is compressed, it stores elastic potential energy and generates an upward reaction force, which provides shaking for the equipment. The shaking process effectively enhances the screening effect of the screening plate, especially helps the separation of fine materials, and ensures the uniformity and efficiency of the material screening process.
[0024] (2) By starting the telescopic device, the drive end of the telescopic device drives the connecting block to move. The movement of the connecting block further drives the moving rod to move. The movement of the moving rod drives the protrusion to move, which in turn drives the air regulating plate to rotate on the inner wall of the box. The rotation of the air regulating plate realizes the precise adjustment of the air direction inside the box, optimizes the airflow distribution, and by adjusting the airflow direction and speed, the particles can be heated and dried more evenly inside the box, avoiding the problem of local areas being too dry or not completely dry, thereby improving the drying effect, further enhancing the stability and consistency of the drying process, and ensuring the quality of the product and the efficiency of the operation.
[0025] In summary, this utility model has the advantages of being able to screen dried materials and adjust airflow direction. Attached Figure Description

[0042] Work steps
[0043] By starting motor 3, the drive end of motor 3 can drive the convex rod 4 to rotate. The rotation of the convex rod 4 can drive the rotating rod 5 to reciprocate in the vertical direction. The rotating rod 5 can drive the connecting rod 6 to move. The clamp at the top of the connecting rod 6 can move inside the limiting block 7, and at the same time drive the limiting block 7 to move. This can drive the fine material screening plate 8, the medium material screening plate 9, and the coarse material screening plate 10 to move. During the movement, the fine material screening plate 8 can drive the fixed plate 11 to press down, which can compress the spring 13. During the compression process, the spring 13 can generate elastic potential energy, providing shaking for the equipment, which can significantly improve the screening effect of the equipment.
[0044] By activating the expansion joint 17, the drive end of the expansion joint 17 can move the connecting block 18. The movement of the connecting block 18 can move the moving rod 19. The moving rod 19 can move the protrusion 20, thereby causing the air regulating plate 21 to rotate on the inner wall of the box 16. This allows for the adjustment of the airflow direction inside the box 16, optimizing the airflow distribution and ensuring that the particles are heated and dried more evenly in the bed, avoiding the phenomenon of some areas being too dry or not completely dry.
