Description

Technical Field

[0001] This application relates to the field of fluidized bed dryer technology, and in particular to a hopper for an efficient fluidized bed dryer. Background Art

[0002] The efficient fluidized bed dryer is used for fluidized bed drying of particulate materials with a particle size of 0.1 - 6 mm, and is suitable for drying finished products and intermediates in the pharmaceutical, food, light industry, and chemical industries. When in use, after the air is heated and purified, it is introduced from the lower part by an induced draft fan, passes through the perforated mesh plate of the hopper, and in the working chamber, fluidization is formed through stirring and negative pressure. After the water evaporates quickly, it is taken away with the exhaust gas, so that the material is quickly dried.

[0003] The prior art CN219474161U discloses a hopper for an efficient fluidized bed dryer, which includes a material rack. The lower end of the material rack is rotatably installed with rollers. A hopper is arranged inside the material rack. Both ends of the hopper are rotatably connected to the material rack through rotating shafts. A wire winding seat is installed on one side of the material rack. A fixed pulley is arranged at the upper end of the wire winding seat. A steel wire is wound in the center of the wire winding seat. The other end of the steel wire is fixedly connected to the hopper. A driving motor is installed inside the hopper. A stirring paddle is arranged at the upper end of the driving motor. A slide rail is arranged inside the hopper. A track groove is arranged at the opening of the inner wall of the hopper. A cleaning device is slidably installed at the upper end of the slide rail. One side of the upper end of the cleaning device is slidably installed inside the track groove. By setting the cleaning device, the inner wall of the hopper can be cleaned, and the materials attached to the inner wall are cleaned down, improving the cleaning efficiency and reducing material waste. However, the track groove and the slide rail of the above device are both arranged on the inner wall of the hopper, so that the track groove and the slide rail are easily blocked by materials, thereby reducing the cleaning efficiency of the cleaning device. And the materials are easily adhered to the surface of the cleaning device during the drying process, thereby reducing the cleaning effect of the cleaning device.

[0004] In view of the above related technologies, the inventor believes that the materials are easy to block the track groove and the slide rail, and are easy to adhere to the surface of the cleaning device, thereby reducing the cleaning efficiency and effect of the cleaning device. Summary of the Utility Model

[0005] In order to solve the above technical problems, this application provides a hopper for an efficient fluidized bed dryer.

[0006] A hopper for an efficient fluidized bed dryer provided by this application adopts the following technical solutions:

[0007] An efficient hopper for a fluidized bed dryer, comprising a material rack, a hopper rotatably connected to the material rack, a rotation adjustment assembly arranged on the material rack for driving the hopper to rotate, a cleaning mechanism, a driving assembly for driving the cleaning mechanism to rotate, and a drying mechanism. The driving assembly includes a first gear arranged on the outer wall of the hopper, a mounting plate arranged on the outer wall of the hopper, a driving motor arranged on the mounting plate, a second gear fixedly connected to the transmission shaft of the driving motor, and a connecting rod arranged on the first gear. The first gear meshes with the second gear. The first gear is slidably connected to the outer wall of the hopper, and the connecting rod is detachably connected to the cleaning mechanism.

[0008] By adopting the above technical solution, the drying mechanism dries the materials in the hopper. After the drying process is completed, the rotation adjustment assembly drives the hopper to rotate, thereby realizing the dumping of the materials. After the material dumping is completed, the cleaning mechanism is installed on the connecting rod. The driving motor drives the second gear to rotate, and the second gear drives the first gear and the connecting rod to rotate, thereby driving the cleaning mechanism to clean the inner wall of the hopper. The driving assembly is arranged on the outer wall of the hopper, reducing the phenomenon that the materials affect the rotation of the driving assembly. Installing the cleaning mechanism after the material drying process is completed reduces the phenomenon that the materials adhere to the cleaning mechanism, thereby improving the cleaning effect and efficiency of the cleaning mechanism on the hopper.

[0011] Preferably, a first mounting hole communicating with the clamping groove is formed on the connecting rod, a second mounting hole is formed on the cleaning scraper, and a connecting bolt is inserted into the first mounting hole and the second mounting hole.

[0012] By adopting the above technical solution, the setting of the connecting bolt improves the connection stability between the cleaning scraper and the connecting rod, and further improves the cleaning stability of the cleaning scraper on the hopper.

[0013] Preferably, the cleaning scraper is of an arc-shaped structure.

[0014] By adopting the above technical solution, the cleaning scraper with an arc-shaped structure increases the contact area with the inner wall of the hopper, thereby improving the cleaning efficiency of the cleaning scraper on the hopper.

[0015] Preferably, cleaning inclined surfaces are arranged at both ends of the cleaning scraper for cleaning the materials.

[0016] By adopting the above technical solution, the provision of the cleaning inclined surface reduces the frictional resistance suffered by the cleaning scraper during the process of cleaning the material, thereby improving the cleaning efficiency and service life of the cleaning scraper.

[0017] Preferably, an installation groove is formed on the outer wall of the hopper, and the first gear is slidably connected to the installation groove.

[0018] By adopting the above technical solution, the first gear is slidably connected to the hopper through the installation groove, thereby improving the rotational stability of the first gear, and further improving the stability of the cleaning scraper for cleaning the hopper.

[0019] Preferably, a bottom scraper for cleaning the bottom of the hopper is detachably connected to one end of the cleaning scraper away from the connecting rod.

[0020] By adopting the above technical solution, the provision of the bottom scraper further improves the cleaning effect of the cleaning mechanism on the inner wall of the hopper.

[0021] Preferably, the rotation adjustment assembly includes a first rotating shaft and a second rotating shaft provided on the hopper. Both the first rotating shaft and the second rotating shaft are rotatably connected to the material rack. One end of the first rotating shaft away from the hopper passes through the material rack and is connected to a handwheel. A limit insertion rod is slidably connected to the handwheel. A plurality of limit holes are formed on the material rack, and the limit insertion rod is clamped with the limit holes.

[0022] By adopting the above technical solution, the staff drives the hopper to rotate by rotating the handwheel, thereby realizing the dumping of the material. The staff can limit the handwheel and the hopper by inserting the limit insertion rod into the limit hole, which facilitates the stable progress of the discharging process and the subsequent cleaning process.

[0023] In summary, the present application has the following beneficial technical effects:

[0024] 1. The driving assembly is arranged on the outer wall of the hopper, reducing the phenomenon that the material affects the rotation of the driving assembly. The cleaning mechanism is installed after the material drying process is completed, thereby reducing the phenomenon that the material adheres to the cleaning mechanism, and further improving the cleaning effect and efficiency of the cleaning mechanism on the hopper;

[0025] 2. The cleaning scraper with an arc-shaped structure increases the contact area with the inner wall of the hopper, thereby improving the cleaning efficiency of the cleaning scraper on the hopper;

[0026] 3. The provision of the bottom scraper further improves the cleaning effect of the cleaning mechanism on the inner wall of the hopper. BRIEF DESCRIPTION OF THE DRAWINGS
