Description

Technical Field

[0001] This application relates to the field of drying fluidized bed technology, and more particularly to an air distribution plate device for a drying fluidized bed. Background Technology

[0002] The air distribution plate is an important component of a fluidized bed dryer, with evenly distributed air distribution holes to ensure that air is blown uniformly onto the material. During use, the air distribution holes are easily clogged by the material, resulting in a lower fluidization drying effect of the fluidized bed. Utility Model Content

[0003] In view of this, the purpose of this application is to provide an air distribution plate device for drying fluidized beds, so as to clean the air distribution plate and prevent the air distribution holes from being blocked.

[0004] The technical solution of this application is as follows:

[0005] This application provides an air distribution plate device for a drying fluidized bed, including an air distribution plate disposed inside the drying fluidized bed body, an air guide pipe passing through the air distribution plate, a wind-driven rotating shaft inside the air guide pipe, and a brush abutting against the air distribution plate on the rotating shaft.

[0006] By adopting the technical solution of this application, some air flows into the air duct and drives the rotating shaft to rotate, which in turn drives the brush to clean the air distribution plate, thus preventing the air distribution holes from being blocked by materials.

[0007] In some implementations, the air duct and the air distribution plate are arranged coaxially.

[0008] In some implementations, a connecting rod is provided between the outer wall of the air duct and the inner wall of the air inlet duct of the drying fluidized bed.

[0009] In some implementations, the connecting rods are evenly distributed along the circumference of the air duct.

[0010] In some implementations, the connecting rod is arranged radially along the air duct.

[0011] In some implementations, the air duct has blades inside that are connected to the rotating shaft.

[0012] In some implementations, a base for mounting the rotating shaft is fixed inside the air duct.

[0013] In some implementations, the base includes a cylindrical shell and a support rod arranged along the diameter of the shell, with a pivot rotatably arranged on the support rod.

[0014] In some implementations, the rotating shaft and the air duct are arranged coaxially.

[0015] In some implementations, the brush bristles are evenly distributed circumferentially along the axis of rotation. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0023] In related technologies, the air distribution plate 21 is an important component of the drying fluidized bed 10, and it is evenly distributed with air distribution holes 21 to ensure that the air is blown evenly onto the material. During use, the air distribution holes 21 are easily blocked by the material, resulting in a low fluidization drying effect of the fluidized bed.

[0024] In view of this, the purpose of this embodiment is to provide an air distribution plate device for drying fluidized beds, so as to clean the air distribution plate and prevent the air distribution holes from becoming blocked.

[0025] Please see Figures 1-2 In this embodiment, a drying fluidized bed air distribution plate device includes an air distribution plate 20 disposed inside the drying fluidized bed body 10, an air guide pipe 22 passing through the air distribution plate 20, a wind-driven rotating shaft 23 disposed inside the air guide pipe 22, and a brush 27 abutting against the air distribution plate 20 on the rotating shaft 23.

[0026] Using the technical solution of this embodiment, some air flows into the air duct 22 and drives the rotating shaft 23 to rotate, thereby driving the brush 27 to clean the air distribution plate 20, which can prevent the air distribution hole 21 from being blocked by materials.

[0027] It should be noted that a feed pipe 11 is provided above the side wall of the drying fluidized bed 10, and an air inlet pipe 12 is provided at the lower end of the drying fluidized bed 10. The air distribution plate 20 is fixed to the inside of the drying fluidized bed 10. The air distribution plate 20 divides the inner cavity of the drying fluidized bed 10 into upper and lower parts. Air distribution holes 21 are evenly arranged on the air distribution plate 20. The air flowing in from the air inlet pipe 12 is blown into the space above the air distribution plate 20 after passing through the air distribution holes 21.

[0028] In this embodiment, the air distribution plate 20, the air inlet pipe 12, and the drying fluidized bed body 10 are arranged coaxially. The air guide pipe 22 passes through the axis of the air distribution plate 20, that is, the air guide pipe 22 and the air distribution plate 20 are arranged coaxially and are fixedly connected. In order to further improve the stability of the air guide pipe 22, a connecting rod 28 is fixedly connected between the outer wall of the air guide pipe 22 and the inner wall of the dry air inlet pipe 12. The connecting rod 28 is evenly distributed along the circumference of the air guide pipe 22 and arranged along the radial direction of the air guide pipe 22.

[0029] In addition, a base is fixed inside the air duct 22. The base includes a cylindrical shell 25 and a support rod 26 arranged along the diameter of the shell 25. The shell 25 is fixedly connected to the inner wall of the air duct 22. The rotating shaft 23 is rotatably arranged on the support rod 26 and is coaxial with the air duct 22. A blade 24 is fixed on the rotating shaft 23. The blade 24 is arranged inside the shell 25. When the air entering the air duct 22 flows through the blade 24, it can drive the blade 24 to rotate, thereby driving the rotating shaft 23 to rotate.

[0030] In addition, the brush 27 is fixed to the rotating shaft 23 and the brush 27 is evenly distributed along the circumference of the rotating shaft 23. The brush 27 is arranged radially along the rotating shaft 23. The bristles of the brush 27 abut against the upper surface of the air distribution plate 20. The brush 27 rotates synchronously with the rotating shaft 23, which can clean the upper surface of the air distribution plate 20 and prevent material from clogging the air distribution hole 21 to a certain extent.

[0031] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
