[0001] The utility model belongs to the technical field of alumina powder production, and specifically relates to a feeding device for alumina powder production. Background Art

[0002] Alumina powder is an important inorganic material with extremely high hardness. Its resistivity and thermal conductivity make it applicable to a variety of industrial fields, such as ceramics, coatings, plastics, electronic materials, refractory materials, rubber, leather, etc. In addition, alumina powder also has characteristics such as high melting point, high boiling point, and high dielectric constant, and is commonly used as an anti-corrosion agent and filler in the coating industry.

[0003] However, when the current feeding device is feeding, the alumina powder will block the discharge port, and it needs to be cleaned in time to ensure the normal feeding of the alumina powder. However, during the cleaning process, the production of alumina powder will be affected. Therefore, the current feeding device will waste time in cleaning the blocked discharge port and affect the production efficiency of alumina powder. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0021] As shown Figures 1-4 in the following figure, a feeding device for alumina powder production includes a material bucket 1. An outlet 3 is arranged at the bottom end of the material bucket 1. A replacement mechanism is arranged on one side of the outlet 3. The replacement mechanism includes an extension frame 5 fixedly connected to one side of the outlet 3. A driving motor 6 is fixedly installed at the top end of the extension frame 5. The output end of the driving motor 6 is fixedly connected to three connecting rods 7. Each of the three connecting rods 7 is fixedly connected to a main pipe 8 and two auxiliary pipes 9. The positions of the main pipe 8 and the auxiliary pipes 9 can be controlled through the replacement mechanism. When the phenomenon of material blockage occurs during the feeding process of alumina powder, the driving motor 6 will drive the connecting rods 7 and the main pipe 8 and the auxiliary pipes 9 to rotate. The main pipe 8 will be switched to the position of the auxiliary pipe 9 to become the auxiliary pipe 9, and the auxiliary pipe 9 will replace the position of the main pipe 8 to become the main pipe 8. Through the replacement mechanism, the blocked main pipe 8 can be removed, and the unblocked auxiliary pipe 9 can be moved below the outlet 3, so that the feeding of alumina powder can continue to work, saving the cleaning time, thereby improving the working efficiency of alumina powder feeding.

[0022] A solenoid valve 4 is arranged inside the outlet 3. An inlet 2 is arranged at the top end of the material bucket 1. The inlet 2 penetrates through the outlet 3. The solenoid valve 4 can control the discharge of alumina powder, and can control the feeding speed and weight of alumina powder according to the required amount. At the same time, it can also block the feeding of alumina powder, providing convenience for the replacement mechanism.

[0023] An extension mechanism is arranged at the top end of the extension frame 5. The extension mechanism includes two receiving pipes 10 fixedly connected to the top end of the extension frame 5. Telescopic rotary motors 11 are fixedly installed at the top ends of the two receiving pipes 10. The output ends of the two telescopic rotary motors 11 are fixedly connected to telescopic rods 12. The extension mechanism can extend the blockage clearing mechanism, so that the blockage clearing mechanism can penetrate into the blocked auxiliary pipe 9 to clear the blockage of the auxiliary pipe 9, making the auxiliary pipe 9 become a state that supports the passage of alumina powder, providing convenience for the next replacement.

[0024] A blockage clearing mechanism is arranged on the surface of the telescopic rod 12. The blockage clearing mechanism includes a plurality of folding rods 13 rotatably connected to the surface of the telescopic rod 12. Blockage clearing blocks 14 are fixedly connected to the bottom ends of the plurality of folding rods 13. A torsion spring 15 is arranged inside the folding rod 13. The other end of the torsion spring 15 is arranged inside the telescopic rod 12. When the folding rods 13 in the blockage clearing mechanism extend into the auxiliary pipe 9, they will unfold due to the torque of the torsion spring 15. The unfolded folding rods 13 are about the same radius as the auxiliary pipe 9, and the blockage clearing blocks 14 will also closely adhere to the inner wall of the auxiliary pipe 9. They will rise and fall under the drive of the telescopic rotary motor 11, and will also rotate while rising and falling to clean the blocked alumina powder in the auxiliary pipe 9, making the auxiliary pipe 9 become a passable state.

[0025] The clog-removing mechanism is driven by the extending mechanism. The clog-removing mechanism is arranged inside the receiving pipe 10. The torsion spring 15 is located between the folding rod 13 and the telescopic rod 12. The receiving pipe 10 can store the clog-removing mechanism to prevent the clog-removing mechanism from affecting the operation of the replacement mechanism. Due to the action of the torsion spring 15, the folding rod 13 will fold while entering the receiving pipe 10, so that the entire clog-removing mechanism is stored by the receiving pipe 10.

[0026] The main pipe 8 is located directly below the discharge port 3, and the auxiliary pipe 9 is located directly below the receiving pipe 10. As the replacement mechanism operates, the positions of the main pipe 8 and the auxiliary pipe 9 are constantly changing. The main pipe 8 is at the discharge port 3, and the auxiliary pipe 9 is at the receiving pipe 10. The main pipe 8 is the channel for alumina powder to be discharged, and the auxiliary pipe 9 is the pipe for cleaning.

[0027] Working principle: During the process of discharging alumina powder, the speed and quantity of alumina powder discharged are controlled by the solenoid valve 4. However, when the main pipe 8 is blocked, the solenoid valve 4 will close to prevent the alumina powder from continuing to be discharged. At the same time, the driving motor 6 will drive the connecting rod 7 to rotate, moving the blocked main pipe 8 to the position of the auxiliary pipe 9. At the same time, the auxiliary pipe 9 will replace the main pipe 8. After the replacement mechanism finishes working, the solenoid valve 4 will open to control the continuous discharge of alumina powder. At the same time, the telescopic and rotating motor 11 will drive the telescopic rod 12 to extend. When the telescopic rod 12 extends out of the receiving pipe 10, the folding rod 13 will pop out due to the torque of the torsion spring 15 and then enter the blocked auxiliary pipe 9 to clean the auxiliary pipe 9 and remove the blocked alumina powder. If there is another blockage, this process can be carried out again to ensure the efficiency of alumina powder discharge.
