In particular, the reactor 9 used in the oxide powder production apparatus of the present invention is divided into a plurality of regions and heated, and the same heating temperature can be maintained in the entire region inside the reactor 9;

[0035] Furthermore, by providing a one-way valve 513, the air above the second piston plate 57 can flow downward, while the air below the second piston plate 57 cannot flow upward;

[0036] When piston plate 1 56 moves downward and piston plate 2 57 cannot move downward, the air above the filter plate 4 will enter the interior of the circular box 51 through multiple air inlet holes 514 and finally enter between piston plate 1 56 and piston plate 2 57 through multiple one-way valves 513.

[0037] The locking mechanism 59 includes two fixed seats 592 fixedly mounted on the inner wall of the top of the round box 51 and a fixed plate 591 fixedly mounted on the top of the piston plate 2 57. The two fixed seats 592 are rotatably mounted with the same rotating shaft 3 593. The rotating shaft 3 593 is slidably sleeved with two sleeve sliders 594. A swing arm 595 is hingedly connected between the two sleeve sliders 594 and the fixed plate 591. Two rotating blocks 596 are rotatably sleeved on the sleeve slider 594. The ends of the two rotating blocks 596 that are away from each other are fixedly mounted with springs 2 597. The ends of the two springs 2 597 that are away from each other are respectively fixedly connected to the corresponding sleeve sliders 594, and the two springs 2 597 are slidably sleeved on the rotating shaft 3 593.

[0038] A gear 598 is fixedly sleeved on the rotating shaft three 593, and a rack 5910 is meshedly connected to the gear 598. A push-pull rod 599 is fixedly installed on the bottom end of the rack 5910. The push-pull rod 599 passes through the piston plate two 57 and the fixed plate 591 and is slidably connected to the piston plate two 57 and the fixed plate 591. A stopper 5911 is fixedly sleeved on the push-pull rod 599, and the stopper 5911 is located above the fixed plate 591. A pull ring 5912 is fixedly installed on the bottom end of the push-pull rod 599.

[0039] A sliding groove 5941 is provided on the sleeve slider 594 , and two clamping blocks 5931 are fixedly installed on the rotating shaft 3 593 .

[0040] The reset mechanism 58 includes two rectangular frames 581 fixedly connected to the top of the piston plate 56, the same spring 1 585 is fixedly installed on the top of the two springs 1 585, two symmetrically distributed clamping arms 582 are rotatably sleeved on the spring 1 585, the bottom ends of the two clamping arms 582 are hinged with hinged arms 583, the two hinged arms 583 are rotatably installed with the same rotating shaft 1 584 at one end close to each other, the rotating shaft 1 584 is slidably connected to the inner walls of the two rectangular frames 581, the same rotating shaft 2 586 is fixedly installed between the two clamping arms 582, the top of the clamping arms 582 is provided with a slope 5821, and the sides of the two clamping arms 582 close to each other are provided with a slot 5822.

[0041] In this embodiment: when in use, the airflow enters the separation box 1 through the air inlet pipe 2, and the fan blades 32 driven by the motor 31 will pull the airflow upward. At this time, the large-particle powder particles in the airflow will fall under the action of gravity and eventually be discharged from the bottom conical opening of the separation box 1, while the small-particle powder particles will float upward with the rising airflow, and finally be filtered by the filter plate 4. The airflow is directly discharged from the multiple air outlets 12 on the top of the separation box 1, and the small-particle powder particles will accumulate at the bottom of the filter plate 4;

[0042] During the rotation of the fan blades 32, the driving rod 33 will drive the round box 51 to rotate. During the rotation of the plurality of rectangular boxes 53, the powder particles at the bottom of the filter plate 4 will enter the rectangular box 53 through the ash inlet 531 and will then be scraped off by the top inner wall on the other side. After the scraped powder particles fall into the rectangular box 53, the suction force from top to bottom will be generated by the activated exhaust fan 62, and the suction force will be transmitted to the plurality of rectangular boxes 53 through the round box 51. At this time, the powder particles in the rectangular box 53 will be sucked into the discharge pipe 61 by the suction force and finally discharged from the bottom opening of the discharge pipe 61.

[0043] During the rotation of the round box 51, the telescopic rod 55 is started to continuously extend and retract. When the telescopic rod 55 pushes the piston plate 1 56 to move upward, the air between the piston plate 1 56 and the piston plate 2 57 will be compressed. When the piston plate 1 56 drives the reset mechanism 58 to move upward, as the two slopes 5821 contact the pull ring 5912, the two clamping arms 582 will be pushed open. At this time, the pull ring 5912 will enter the groove 5822 between the two clamping arms 582 and contact the bottom inner wall of the groove 5822. At this time, under the reset elastic force of the squeezed rotating shaft 2 586, the tops of the two clamping arms 582 will be re-contacted together, and then the reset mechanism 58 will push the push-pull rod 599 upward during the rising process.

[0044] During the upward movement of the locking mechanism 59, the gear 598 will be driven to rotate through the rack 5910, and the rotation of the gear 598 will drive the rotation of the shaft 3 593. As the shaft 3 593 rotates, when the two blocks 5931 coincide with the corresponding slide grooves 5941, the two compressed springs 2 597 will quickly reset and push the two sleeve sliders 594 away from each other. At this time, the two blocks 5931 will enter the corresponding slide grooves 5941. The two sleeve sliders 594 will move away from each other and drive the fixed plate 591 to move upward through the two swing arms 595. The upward movement of the fixed plate 591 will drive the movable The plug plate 57 moves upward rapidly, and when the mounting hole 512 blocked by the piston plate 57 is exposed, the compressed air between the piston plate 56 and the piston plate 57 will quickly enter the multiple rectangular boxes 52 through the multiple mounting holes 512, and form impact gas from top to bottom in the rectangular box 52. Under the impact of the gas, the powder particles blocked in the holes of the filter plate 4 can be blown out and fall into the rectangular box 53. After the piston plate 57 moves upward, the pull ring 5912 will abut against the top inner wall of the two slots 5822.

[0045] When the two sleeve sliders 594 move away from each other, the two clamping blocks 5931 will pass through the corresponding sliding grooves 5941 and move between the two sleeve sliders 594. At this time, the teeth on the rack 5910 are separated from the teeth on the gear 598. Then, when the two sleeve sliders 594 move away from each other, the fixing plate 591 will rise and fit with the bottom of the stopper 5911.

[0046] When the telescopic rod 55 drives the piston plate 1 56 to move downward, the two clamping arms 582 will pull the pull ring 5912 downward, and the pull ring 5912 moves downward and then drives the fixed plate 591 to move downward through the push-pull rod 599 and the stopper 5911. The downward movement of the fixed plate 591 will pull the two sleeve sliders 594 closer to each other through the two swing arms 595 and compress the corresponding spring 2 597. At this time, the two card blocks 5931 will respectively pass through the corresponding slide grooves 5941. At this time, the two sleeve sliders 594 are located between the two card blocks 5931. As the push-pull rod 599 moves downward, the teeth on the rack 5910 will mesh with the gear 598 and drive the gear 598 to rotate. After the gear 598 rotates half a circle, the rack 5910 will be separated from it. At this time, the two sleeve sliders 594 will be pushed against the corresponding card blocks 5931 by the compressed spring 2 597 respectively.

[0047] When the second piston plate 57 is pulled and cannot move downward, the pull ring 5912 cannot move either. As the reset mechanism 58 moves downward, the pull ring 5912 abuts against the tops of the two clamping grooves 5822 to separate the tops of the two clamping arms 582. Finally, the pull ring 5912 moves out of the separated two clamping arms 582, and the piston plate 1 56 can continue to move downward.

[0048] Then, as the telescopic rod 55 is continuously extended and retracted, the air between the piston plate 1 56 and the piston plate 2 57 will be continuously compressed, and then the powder particles blocked in the holes of the filter plate 4 can be blown away from top to bottom by the quickly released compressed air.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
