Technical Field

[0001] The utility model relates to the technical field of fluidized bed dryers, in particular to a fluidized bed dryer with a stirring function. Background Art

[0002] A fluidized bed dryer is a device for drying materials, also known as a fluidized bed. It dries the materials by using hot air and air pressure, achieving the drying process of the materials. The design of this device aims to improve the fluidity of the materials, reduce dust flying, and improve the dissolution performance through powder granulation.

[0003] When some fluidized bed dryers are drying materials, the hot air circulates in the drying cylinder, and the materials also flow in the drying cylinder along with the hot air. However, during this process, some materials will accumulate together because they carry moisture, resulting in incomplete drying of each material particle during the flow. Summary of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fluidized bed dryer with a stirring function includes a mounting frame. A lifting seat is arranged at the bottom of the mounting frame. Above the lifting seat is a material hopper, and the material hopper is installed on a support frame. The support frame is located on one side of the mounting frame. A driving mechanism is arranged inside the material hopper, and a stirring mechanism is rotatably arranged at the bottom of the driving mechanism.

[0007] The stirring mechanism includes a rotating shaft. Symmetrically fixed to the middle of the rotating shaft body are first stirring rods. On the other side of the first stirring rod away from the rotating shaft is a scraper plate, and scraping blades are arranged on the side wall of the scraper plate away from the first stirring rod.

[0008] In addition, preferably, a main cylinder is arranged above the material hopper on the mounting frame, and a filter bag cylinder is arranged above the main cylinder.

[0009] In addition, preferably, a drying cavity is vertically opened inside the material hopper, and both the driving mechanism and the stirring mechanism are arranged in the drying cavity.

[0010] In addition, preferably, the scraping blades are in contact with the inner wall of the drying cavity, and a plurality of second stirring rods are evenly arranged below the first stirring rod on the rotating shaft.

[0011] In addition, preferably, the driving mechanism includes a base, and a stirring motor is arranged in the middle of the upper surface of the base. The output end at the bottom of the stirring motor is assembled and connected to a rotating shaft.

[0012] In addition, a preferred structure is that a protective cover is fixed on the upper surface of the base, the protective cover covers the outside of the stirring motor, and a plurality of fixing rods are uniformly and fixedly connected to the outer wall of the protective cover.

[0014] The beneficial effects of the present utility model are as follows: by arranging a driving mechanism in the drying cavity, the stirring mechanism driven by the bottom of the driving mechanism can rotate, so that the fluidized bed dryer has the function of stirring. While the first stirring rod and the second stirring rod are rotating, they strike the flowing materials in the drying cavity, so as to disperse some materials that are stuck together in the drying cavity.

Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-5, A fluidized bed dryer with a stirring function, comprising a mounting frame 1. A lifting seat 6 is provided at the bottom of the mounting frame 1. Above the lifting seat 6 is a material hopper 2, and the material hopper 2 is installed on a support frame 3. The support frame 3 is located on one side of the mounting frame 1. Inside the material hopper 2 is a driving mechanism 7. At the bottom of the driving mechanism 7 is rotatably arranged a stirring mechanism 8. The stirring mechanism 8 includes a rotating shaft 81. Symmetrically fixed to the middle of the shaft body of the rotating shaft 81 are first stirring rods 82. On the other side of the first stirring rod 82 away from the rotating shaft 81 is provided a scraper plate 84. On the other side wall of the scraper plate 84 away from the first stirring rod 82 are provided scraping blades 841. The stirring mechanism 8 can effectively disperse the flowing materials in the drying chamber 21, thereby preventing some materials from sticking together in blocks, and the scraping blades 841 can scrape the material particles on the inner wall of the drying chamber 21.

[0023] Among them, above the material hopper 2 on the mounting frame 1 is provided a main body cylinder 4, and above the main body cylinder 4 is provided a filter bag cylinder 5.

[0024] In addition, a drying chamber 21 is vertically and throughly opened inside the material hopper 2. Both the driving mechanism 7 and the stirring mechanism 8 are arranged in the drying chamber 21. The driving mechanism 7 and the stirring mechanism 8 can be moved out in cooperation with the support frame 3 along with the material hopper 2.

[0025] Moreover, the scraping blades 841 are in contact with the inner wall of the drying chamber 21. Below the first stirring rods 82, a plurality of second stirring rods 83 are evenly arranged on the rotating shaft 81. The second stirring rods 83 can also rotate to disperse the flowing materials in the drying chamber 21.

[0026] At the same time, the driving mechanism 7 includes a base 74. In the middle of the upper surface of the base 74 is provided a stirring motor 75. The bottom output end of the stirring motor 75 is assembled and connected to the rotating shaft 81. Fixed on the upper surface of the base 74 is a protective cover 71. The protective cover 71 covers the outside of the stirring motor 75. A plurality of fixing rods 72 are evenly and fixedly connected to the outer wall of the protective cover 71. The protective cover 75 can prevent the stirring motor 75 from being affected by the materials.

[0027] In addition, the other end of the fixing rod 72 away from the protective cover 71 is fixedly connected to the inner wall of the material hopper 2. On one side wall of the protective cover 71 is provided a drain pipe 73 communicating with it. The drain pipe 73 extends to the outside of the material hopper 2. The drain pipe 73 facilitates the connection of the connecting wire of the stirring motor 75 to the outside.

[0028] In this embodiment, when the fluidized bed dryer is performing the material drying work, hot air blows up from the bottom of the material hopper 2, so as to realize that the materials are in a flowing state in the drying chamber 21 of the material hopper 2. At this time, the driving mechanism 7 drives the stirring mechanism 8 to stir.

[0029] The stirring motor 75 drives the rotating shaft 81 to rotate, thereby driving the first stirring rod 82 and the second stirring rod 83 to rotate. During this process, while rotating, the first stirring rod 82 and the second stirring rod 83 strike the flowing materials in the drying chamber 21, thereby dispersing some of the materials that are sticky together in the drying chamber 21, so as to facilitate better drying of the materials. And the scraping blade 841 on the scraping blade plate 84 will contact the inner wall of the material hopper 2, thereby scraping off some of the material particles sticking to the inner wall of the drying chamber 21.

[0030] In the present utility model, by providing a driving mechanism 7 in the drying chamber 21, the stirring mechanism 8 driven by the bottom of the driving mechanism 7 can rotate, so that the fluidized bed dryer has the function of stirring. While rotating, the first stirring rod 82 and the second stirring rod 83 strike the flowing materials in the drying chamber 21, thereby dispersing some of the materials that are sticky together in the drying chamber 21. This kind of fluidized bed dryer with a stirring function effectively prevents the materials from sticking together and improves the drying effect of the materials.
