Description

Technical Field

[0001] This utility model relates to the field of rotary flash drying technology, specifically a rotary flash drying device for crushing materials. Background Technology

[0002] The rotary flash dryer achieves efficient drying through forced mixing of hot air and materials, mechanical crushing, and grading. Its working principle can be divided into five stages: material entry, crushing, gas-solid contact, drying, and grading.

[0003] The prior art discloses a rotary flash dryer with announcement number CN215490599U, comprising a drying cylinder, a feed pipe, a discharge pipe, and a stirring paddle. The feed pipe is located in the middle of the drying cylinder, the discharge pipe is located at the top of the drying cylinder, a first stirring paddle is located at the bottom of the drying cylinder, a second stirring paddle is located inside the hopper, and a fan coil unit for blowing hot air is located at the bottom of the drying cylinder. The upper surface of the fan coil unit is evenly distributed with blowing pipes, and the bottom of the fan coil unit is connected to an external fan with a heater via an air duct. A feeding auger is located inside the feed pipe, with one end extending into the drying cylinder and the other end extending directly below the hopper. The material is initially pulverized by the second stirring paddle in the hopper and then further pulverized by the first stirring paddle in the drying cylinder, ensuring effective pulverization and improving drying efficiency. The fan coil unit at the bottom of the drying cylinder ensures uniform blowing and drying, eliminates dead zones, prevents blockage at the bottom of the cylinder, and improves drying efficiency.

[0004] One end of the aforementioned feeding auger extends into the drying cylinder, but the feeding auger is not equipped with a support device, resulting in the other end of the feeding auger being heavier. This causes a gap to form between the feeding auger and the drying cylinder, causing the feeding auger to detach from the drying cylinder, thus preventing the material from being effectively conveyed into the drying cylinder.

[0028] The rotary flash dryer 1 includes a drying shell 11, a stirring rod 12 is installed at the bottom of the drying shell 11, a drive motor 14 is bolted to the bottom surface of the stirring rod 12, an exhaust device 15 is installed at the bottom of the drying shell 11, and a support assembly 13 is installed on the top surface of the drying shell 11.

[0029] The support assembly 13 includes a feeding shell 131, a feeding pipe 134 welded to the bottom surface of the feeding shell 131, a limit cover plate 138 bolted to the left side surface of the feeding pipe 134, and a variable frequency motor 132 bolted to the left side surface of the limit cover plate 138.

[0030] A stirring blade 133 is installed on the right side surface of the rotor of the variable frequency motor 132. The feed pipe 134 is bolted to the top of the left side surface of the drying shell 11. The stirring blade 133 is installed on the inner wall surface of the feed pipe 134. The drying shell 11 determines the position of the feed pipe 134 and the stirring blade 133, which facilitates the disassembly and replacement of the stirring blade 133 and the feed pipe 134.

[0031] Support blocks 136 are installed at both ends of the feed pipe 134. A threaded rod 137 is fixedly connected to the bottom surface of the support block 136. A support frame 135 is connected to the bottom surface of the support block 136. The threaded rod 137 is inserted into the top of the support frame 135. A nut rotates on the surface of the threaded rod 137, locking the support block 136 and the support frame 135 together via the threaded rod 137, facilitating the disassembly and replacement of the support block 136. Two suction devices 15 are installed at the bottom of the support frame 135, arranged front and rear. The suction devices 15 are used to dry the outer surface of the feed pipe. Gas is blown inside the shell 11. The control box 2 is installed at the bottom of the support frame 135. The support frame 135 determines the position of the control box 2. The control box 2 operates the heating device 3 and adjusts the temperature of the heating device 3. The heating device 3 is installed at the bottom of the drying shell 11 and on the left side of the support frame 135. The support frame 135 determines the position of the drying shell 11 and the heating device 3. The drying shell 11 is installed on the left side of the support frame 135. The support frame 135 determines the position of the drying shell 11, which facilitates the disassembly and replacement of the drying shell 11 and protects the safety of the drying shell 11.

[0032] In use, the material is put into the inside of the feeding shell 131 and enters the inside of the feeding pipe 134 through the feeding shell 131. Then, the variable frequency motor 132 is started. The rotor of the variable frequency motor 132 drives the stirring blade 133 to rotate. The stirring blade 133 stirs and transports the material inside the feeding pipe 134 and crushes the material at the same time.

[0033] The stirring blades 133 continuously transport the material, which enters the interior of the drying shell 11 through the feed pipe 134, allowing the material to fall into the bottom of the drying shell 11.

[0034] Start the heating device 3, and adjust the position of the heating device 3 by controlling the box 2 to adjust to a suitable temperature for the material. At the same time, the rotor of the drive motor 14 drives the stirring rod 12 to rotate, and the stirring rod 12 can crush the material inside the drying shell 11.

[0035] The air extraction device 15 is started, and the air extraction device 15 draws air and delivers it into the interior of the drying shell 11. At the same time, the heating device 3 continuously heats the drying shell 11, and the drying shell 11 heats and dries the material being crushed.

[0036] At the same time, the air drawn by the air extraction device 15 blows the material upward. After drying, the material is transported through the discharge port at the top of the drying shell 11, thus increasing the service life of the device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
