[0002] Alumina ceramic fine powder is an important industrial raw material with the characteristics of high chemical stability, high hardness, high temperature resistance and good insulation. It is widely used in ceramics, electronic components, coatings and other fields. The storage of alumina ceramic fine powder requires comprehensive consideration of temperature, humidity, containers and packaging, ventilation and separation and other aspects. Only by ensuring that the storage environment is suitable, the containers and packaging are intact, and the management is standardized, can the excellent performance of alumina ceramic fine powder be maintained and its stability and reliability during use be ensured.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4, an alumina ceramic fine powder storage device, comprising a storage tank 1, wherein the top of the storage tank 1 is provided with a feed hopper 6 and an exhaust port 7, the bottom of the storage tank 1 is provided with a discharge port 8, the storage tank 1 is provided with a stirring rod 10 inside, the stirring rod 10 is rotatably connected to the bottom of the storage tank 1, a plurality of stirring rods 11 are fixed to the outside of the stirring rod 10, a rotating part 9 is connected to the lower end of the stirring rod 10, the rotating part 9 is used to drive the stirring rod 10 to rotate, a support plate 12 is fixed to the upper end of the stirring rod 10, a plurality of rotating rods 13 distributed in a circle are penetrated inside the support plate 12, the rotating rods 13 are all rotatably connected to the support plate 12, and the rotating rods 13 are fixed with stirring blades 15 distributed symmetrically outside, and the rotating rods 13 are connected with a self-rotation mechanism 3, when the support plate 1 2 drives the rotating rod 13 to move in a circle, and the self-rotation mechanism 3 is used to drive the rotating rod 13 to rotate. The rotating rod 13 is penetrated by a transmission rod 14. The upper end of the transmission rod 14 is connected to the exhaust mechanism 4, and the lower end of the transmission rod 14 is connected to the discharging mechanism 5. The exhaust mechanism 4 is used to control the water vapor inside the storage tank 1 to be discharged from the exhaust port 7, and the discharging mechanism 5 is used to control the alumina ceramic fine powder inside the storage tank 1 to be discharged from the discharging port 8. The transmission rod 14 is slidably connected to the inner wall of the rotating rod 13 through the driving mechanism 2. The driving mechanism 2 is used to drive the transmission rod 14 to move up and down, so that the transmission rod 14 can respectively drive the exhaust mechanism 4 and the discharging mechanism 5 to operate. The side wall of the storage tank 1 is provided with a heating mechanism for heating the alumina ceramic fine powder.

[0032] In this embodiment, when the device stores alumina ceramic fine powder, the alumina ceramic fine powder is poured into the storage tank 1 through the feed hopper 6, and the storage tank 1 stores the alumina ceramic fine powder. After the alumina ceramic fine powder is poured into the storage tank 1, a cover body (not shown in the figure) is covered on the top of the feed hopper 6, so that the alumina ceramic fine powder is sealed and stored. When the alumina ceramic fine powder is stored for a long time and becomes damp, the alumina ceramic fine powder is heated by the heating mechanism inside the side wall of the storage tank 1 (the heating mechanism can be a heating component such as a heating wire, which is a prior art and is not shown in the figure. I will not elaborate on this here. In the process of heating the alumina ceramic fine powder, the rotating part 9 drives the stirring rod 10 to rotate. The rotating part 9 can be a motor fixed to the outer bottom of the storage tank 1. When the stirring rod 10 rotates, it drives the stirring rod 11 to rotate. The alumina ceramic fine powder is stirred by the stirring rod 11. On the other hand, the stirring rod 10 drives the support plate 12 to rotate. The support plate 12 drives multiple rotating rods 13 to move in a synchronous circular motion. When the rotating rod 13 moves in a circular motion, the rotation mechanism 3 drives the rotating rod 13 to rotate. The rotating rod 13 drives the stirring blade 15 to move in a circular motion and rotate, thereby heating the storage tank. The alumina ceramic powder inside the storage tank 1 rolls inside and outside, so that the alumina ceramic powder inside the storage tank 1 is evenly heated, effectively ensuring the drying effect of the alumina ceramic powder. In addition, while the rotating rod 13 rotates, the driving mechanism 2 drives the transmission rod 14 to rotate, and the transmission rod 14 drives the exhaust mechanism 4 to operate, so that the water vapor generated during the drying process of the alumina ceramic powder can be discharged from the exhaust port 7 in time, avoiding the phenomenon that the water vapor generated during the drying process of the alumina ceramic powder remains in the storage tank 1 so that the alumina ceramic powder is damp again, further ensuring the oxygen The drying effect of alumina ceramic fine powder is improved. When alumina ceramic fine powder is needed, the driving mechanism 2 drives the transmission rod 14 to move downward. When the transmission rod 14 drops to a certain extent, the transmission rod 14 rotates and drives the discharging mechanism 5 to operate, thereby controlling the alumina ceramic fine powder inside the storage tank 1 to be discharged from the discharge port 8. The alumina ceramic fine powder can be taken out from the storage tank 1 without manually opening the cover body, which saves manpower and ensures the sealing performance between the cover body and the feed hopper 6, thereby avoiding the alumina ceramic fine powder from being damp or contaminated when the staff opens the cover body for a long time.

[0033] See also Figure 3 , Figure 4 and Figure 6The driving mechanism 2 includes a magnetic ring 22 arranged above the transmission rod 14, a connecting plate 23 is fixed on the inner wall of the magnetic ring 22, and a lifting assembly is connected to the top of the connecting plate 23. The lifting assembly is used to drive the connecting plate 23 to move up and down. A magnet 21 is fixed to the top of the transmission rod 14. The magnetism of the magnet 21 is the same as that of the magnetic ring 22. The transmission rod 14 is slidably connected to the inner wall of the rotating rod 13 through the transmission assembly. The transmission assembly is used to limit the transmission rod 14 so that the transmission rod 14 can rotate with the rotating rod 13;

[0034] Initially, the transmission rod 14 is in a higher position, and the rotating rod 13 rotates while driving the transmission rod 14 to rotate through the transmission assembly, and the transmission rod 14 drives the exhaust mechanism 4 to operate, so that the water vapor generated during the drying process of the alumina ceramic fine powder can be discharged from the exhaust port 7 in time. When the alumina ceramic fine powder is dried, the rotating rod 13 stops rotating, the exhaust mechanism 4 stops operating, and the exhaust port 7 is in a closed state, thereby sealing the storage tank 1. When the alumina ceramic fine powder needs to be used, the connecting plate 23 is driven downward by the lifting assembly, and the connecting plate 23 drives the magnetic ring 22 to move downward, and the repulsive force between the magnetic ring 22 and the magnet 21 drives the transmission rod 14 to move downward. At this time, the rotating rod 13 During the rotation, the discharging mechanism 5 is driven to operate through the transmission rod 14 instead of the exhaust mechanism 4. The alumina ceramic fine powder can be taken out from the storage tank 1 without manually opening the cover, which saves manpower. At the same time, the exhaust port 7 is always in a closed state during the entire discharging process, thereby avoiding the phenomenon that moisture in the air of the alumina ceramic fine powder enters the storage tank 1 through the exhaust port 7 during the discharging process, thereby ensuring the dryness of the alumina ceramic fine powder. In addition, the arrangement of the magnet 21 and the magnetic ring 22 does not require contact with the transmission rod 14 to make the transmission rod 14 move up and down, so that the transmission rod 14 can also rotate during the circular motion, thereby ensuring the movement effect of the transmission rod 14.

[0035] See also Figure 6 The transmission assembly includes a limit block 213 fixedly connected to the outer wall of the transmission rod 14 and symmetrically distributed, and a limit groove 212 symmetrically distributed is provided on the inner wall of the rotating rod 13, the limit block 213 is located inside the limit groove 212 and is slidably connected to the limit groove 212, wherein a first elastic member 214 is fixed to the bottom of the limit block 213, and the lower end of the first elastic member 214 is fixedly connected to the inner bottom of the limit groove 212;

[0036] When the rotating rod 13 rotates, the transmission rod 14 is driven to rotate through the cooperation of the limit block 213 and the limit groove 212, and the setting of the limit block 213 and the limit groove 212 enables the transmission rod 14 to move up and down inside the rotating rod 13, so that the transmission rod 14 can respectively control the operation of the exhaust mechanism 4 and the discharging mechanism 5. When the magnetic ring 22 moves downward, the transmission rod 14 is driven to move downward by the repulsive force between the magnetic ring 22 and the magnet 21, and the transmission rod 14 drives the limit block 213 to move downward, and the first elastic member 214 is in a compressed state. When the magnetic ring 22 moves upward, the repulsive force of the magnetic ring 22 on the magnet 21 is reduced, and the first elastic member 214 releases elastic potential energy, thereby driving the transmission rod 14 to move upward through the limit block 213, wherein the first elastic member 214 can be a spring.

[0037] See also Figure 3 and Figure 5 The lifting assembly includes a push rod 24 fixed on the top of the connecting plate 23, a limiting sleeve 25 fixed on the top of the storage tank 1, the push rod 24 passes through the top of the storage tank 1 and the limiting sleeve 25 and is slidably connected to the two, a push block 27 is fixed on the top of the push rod 24, a second elastic member 26 is fixed on the bottom of the push block 27, and the lower end of the second elastic member 26 is fixedly connected to the top of the limiting sleeve 25, wherein a fixing component is provided inside the limiting sleeve 25, and the fixing component is used to fix the push rod 24;

[0038] Initially, the magnetic ring 22 is at the highest point under the action of the connecting plate 23, the push rod 24, the push block 27 and the second elastic member 26. The second elastic member 26 can be a spring. At this time, the magnetic ring 22 does not repel the magnet 21, and the transmission rod 14 is at the highest point. When the transmission rod 14 rotates, it drives the exhaust mechanism 4 to operate. When alumina ceramic fine powder is needed, the push block 27 drives the push rod 24 to move downward, and the push rod 24 drives the magnetic ring 22 to move downward through the connecting plate 23, so that the magnetic ring 22 repels the magnet 21 and drives the transmission rod 14 to move downward until the transmission rod 14 can drive the discharging mechanism 5 to operate. When the transmission rod 14 drives the discharging mechanism 5 to operate, the fixing component inside the limit sleeve 25 will automatically fix the push rod 24, thereby fixing the magnetic ring 22 and ensuring the repulsion of the magnetic ring 22 on the magnet 21.

[0039] See also Figure 5 The fixing component includes a positioning pin 29 that penetrates the side wall of the limiting sleeve 25, a stopper 211 is fixed to one end of the positioning pin 29, a third elastic member 210 is fixed to the side wall of the stopper 211, and one end of the third elastic member 210 away from the stopper 211 is fixedly connected to the outer wall of the limiting sleeve 25, and one end of the positioning pin 29 located inside the limiting sleeve 25 is in contact with the side wall of the push rod 24, wherein a positioning groove 28 adapted to the positioning pin 29 is provided on the side wall of the push rod 24;

[0040] The push block 27 drives the push rod 24 to move downward while the positioning pin 29 slides on the surface of the push rod 24. When the transmission rod 14 is able to drive the discharging mechanism 5 to operate, the positioning pin 29 is aligned with the positioning groove 28 on the side wall of the push rod 24. At this time, the end of the positioning pin 29 automatically enters the positioning groove 28 under the action of the stop block 211 and the third elastic member 210, thereby fixing the push rod 24, thereby effectively ensuring the repulsive force of the magnetic ring 22 on the magnet 21, wherein the third elastic member 210 can be a spring.

[0041] See also Figure 3 The self-rotating mechanism 3 includes a gear 32 fixed to the outside of the rotating rod 13, a gear ring 31 is fixed to the inner wall of the storage tank 1, and the gears 32 are meshed with the gear ring 31;

[0042] When drying the alumina ceramic fine powder, the rotating part 9 drives the support plate 12 to rotate through the stirring rod 10, and the support plate 12 drives multiple rotating rods 13 to perform circular motion synchronously. During the circular motion, the external gear 32 of the rotating rod 13 will engage with the toothed ring 31 on the inner wall of the storage tank 1, and the engagement between the toothed ring 31 and the gear 32 drives the rotating rod 13 to rotate. On the one hand, the rotating rod 13 drives the transmission rod 14 to rotate, and on the other hand, it drives the stirring blade 15 to rotate, so that the stirring blade 15 can also rotate during the circular motion, thereby effectively improving the stirring effect of the alumina ceramic fine powder, thereby ensuring the drying effect of the alumina ceramic fine powder.

[0043] See also Figure 3 , Figure 4 and Figure 7 The exhaust mechanism 4 includes a first sealing plate 47 arranged inside the exhaust port 7, a first slide plate 46 is fixed on the side wall of the first sealing plate 47, the first slide plate 46 penetrates the side wall of the storage tank 1, a first baffle plate 44 is fixed on the end of the first slide plate 46, a fourth elastic member 45 is fixed on the side wall of the first baffle plate 44, the other end of the fourth elastic member 45 is fixedly connected to the outer wall of the storage tank 1, a first support rod 43 is fixed on the side wall of the first baffle plate 44, the first support rod 43 penetrates the side wall of the storage tank 1 and is slidably connected to the side wall of the storage tank 1, a first arc plate 42 is fixed on the end of the first support rod 43, and a first extrusion block 41 capable of extruding the first arc plate 42 is fixed on the outside of the transmission rod 14;

[0044] When the alumina ceramic fine powder is dried, the rotating rod 13 rotates and drives the transmission rod 14 to rotate at the same time. When the transmission rod 14 rotates to the position of the first curved plate 42, the transmission rod 14 will squeeze the first curved plate 42 through the first extrusion block 41 during the self-rotation process. The first curved plate 42 drives the first baffle plate 44 to move horizontally through the first support rod 43. The first baffle plate 44 drives the first sealing plate 47 to move horizontally through the first slide plate 46, so that the exhaust port 7 is in an open state. With the self-rotation and circular motion of the transmission rod 14, the degree of extrusion of the first curved plate 42 by the first extrusion block 41 is reduced, and the first baffle plate 44 automatically resets under the action of the fourth elastic member 45. The fourth elastic member 45 can be a spring, thereby driving the first sealing plate 47 to automatically reset, so that the first sealing plate 47 can seal the exhaust port 7. This cycle is repeated, so that the exhaust port 7 is intermittently opened, so that the water vapor generated during the drying process of the alumina ceramic fine powder can be discharged from the exhaust port in time. The exhaust port 7 is used for discharge, thereby avoiding the phenomenon that the moisture generated during the drying process of the alumina ceramic fine powder remains in the storage tank 1 and causes the alumina ceramic fine powder to be damp again. In addition, when drying the alumina ceramic fine powder, there is no need to manually open the cover body, which saves manpower and ensures the sealing performance between the cover body and the feed hopper 6. When the alumina ceramic fine powder is needed, the driving mechanism 2 drives the transmission rod 14 to move downward, and the transmission rod 14 drives the first extrusion block 41 to move downward, so that the first extrusion block 41 and the first arc plate 42 are misaligned. At this time, no matter how the transmission rod 14 rotates, the first extrusion block 41 cannot extrude the first arc plate 42, and the first arc plate 42 is always in the initial position. The first sealing plate 47 always seals the exhaust port 7 under the action of the fourth elastic member 45, thereby avoiding the phenomenon that the moisture in the air of the alumina ceramic fine powder enters the storage tank 1 through the exhaust port 7 during the discharging process, thereby ensuring the dryness of the alumina ceramic fine powder.

[0045] See also Figure 7 The exhaust port 7 is provided with a mesh plate 410 inside, and the mesh plate 410 is slidably connected to the inner wall of the exhaust port 7, wherein the mesh plate 410 is connected to a vibration component, and when the first sealing plate 47 reciprocates, the vibration component is used to drive the mesh plate 410 to vibrate up and down;

[0046] When drying the alumina ceramic fine powder, the alumina ceramic fine powder is filtered through the mesh plate 410, and the water vapor passes through the mesh holes and is discharged directly from the exhaust port 7, and the alumina ceramic fine powder wrapped in the water vapor is adsorbed at the bottom of the mesh plate 410, effectively avoiding the phenomenon of the alumina ceramic fine powder being discharged to the outside of the storage tank 1 through the exhaust port 7 during the drying process, thereby reducing the loss of the alumina ceramic fine powder, and the first sealing plate 47 will reciprocate while driving the mesh plate 410 to vibrate reciprocatingly through the vibration assembly, so that the alumina ceramic fine powder adsorbed at the bottom of the mesh plate 410 falls into the storage tank 1 again, avoiding the phenomenon of the alumina ceramic fine powder blocking the mesh holes, so that the water vapor can be smoothly discharged from the exhaust port 7.

[0047] See also Figure 7 The vibration assembly includes a symmetrically distributed slide groove 412 arranged on the inner wall of the exhaust port 7, and a symmetrically distributed slider 411 is fixed on the side wall of the mesh plate 410, and the slider 411 is located inside the slide groove 412 and is slidably connected to the slide groove 412. A fifth elastic member 413 is fixed to the bottom of each slider 411, and the lower end of the fifth elastic member 413 is fixedly connected to the bottom of the slide groove 412. A protrusion 49 is fixed to the top of the mesh plate 410, and a trapezoidal block 48 for squeezing the protrusion is fixed to the bottom of the first sealing plate 47;

[0048] The first sealing plate 47 reciprocates and drives the trapezoidal block 48 to reciprocate. The trapezoidal block 48 moves and squeezes the protrusion 49 through its inclined surface, so that the mesh plate 410 moves downward. When the trapezoidal block 48 no longer squeezes the protrusion 49, the mesh plate 410 automatically moves upward under the action of the slider 411 and the fifth elastic member 413. The fifth elastic member 413 can be a spring. Such a reciprocating cycle allows the mesh plate 410 to continuously vibrate up and down, and then shake off the alumina ceramic fine powder adsorbed on the bottom of the mesh plate 410 into the storage tank 1, wherein the slide groove 412 can limit the mesh plate 410 through the slider 411, thereby effectively improving the stability of the mesh plate 410 during vibration.

[0050] When the alumina ceramic fine powder is dried, the second extrusion block 51 is always located above the second arc plate 52, the transmission rod 14 cannot extrude the second arc plate 52 through the second extrusion block 51, the second arc plate 52 is always in the initial position, and the second sealing plate 57 always blocks the discharge port 8 under the action of the sixth elastic member 55, the sixth elastic member 55 can be a spring, when the alumina ceramic fine powder is needed, the driving mechanism 2 drives the transmission rod 14 to move downward, and the transmission rod 14 drives the second extrusion block 51 to move downward until the second extrusion block 51 and the second arc plate 52 are on the same horizontal plane, at this time, when the transmission rod 14 rotates to the position of the second arc plate 52, the transmission rod 14 will extrude the second arc plate 52 through the second extrusion block 51 during the self-rotation process, and the second arc plate 52 passes through the second support rod 53. The second baffle plate 54 is driven to move horizontally, and the second baffle plate 54 drives the second sealing plate 57 to move horizontally through the second slide plate 56, so that the discharge port 8 is in an open state. With the rotation and circular motion of the transmission rod 14, the degree of extrusion of the second extrusion block 51 on the second arc plate 52 is reduced, and the second baffle plate 54 is automatically reset under the action of the sixth elastic member 55, thereby driving the second sealing plate 57 to automatically reset, so that the second sealing plate 57 can block the discharge port 8. This cycle is repeated, so that the discharge port 8 can be opened intermittently, thereby achieving the purpose of automatic discharging. The alumina ceramic fine powder can be taken out from the storage tank 1 without manually opening the cover body, which ensures the sealing performance between the cover body and the feed hopper 6 and avoids the alumina ceramic fine powder being damp or contaminated when the staff opens the cover body for a long time.

[0051] Working principle: When storing alumina ceramic fine powder, the device pours the alumina ceramic fine powder into the storage tank 1 through the feed hopper 6, and covers the top of the feed hopper 6, so as to seal and store the alumina ceramic fine powder. When the alumina ceramic fine powder is stored for a long time and becomes damp, the alumina ceramic fine powder is heated by the heating mechanism inside the side wall of the storage tank 1, and at the same time, the stirring rod 10 is driven to rotate by the rotating part 9. On the one hand, the stirring rod 10 drives the stirring rod 11 to rotate, and the alumina ceramic fine powder is stirred by the stirring rod 11. On the other hand, the stirring rod 11 drives the support plate 12 to rotate, and the support plate 12 drives multiple rotating rods 13 to perform synchronous circular motion. During the circular motion of the rotating rod 13, the gear 32 outside the rotating rod 13 will rotate with the storage The toothed ring 31 on the inner wall of the tank 1 is meshed, and the meshing of the toothed ring 31 and the gear 32 drives the rotating rod 13 to rotate, so that the rotating rod 13 can rotate while performing a circular motion. On the one hand, the rotating rod 13 drives the stirring blade 15 to rotate, so that the stirring blade 15 can also rotate during the circular motion, which effectively improves the stirring effect of the alumina ceramic fine powder, thereby ensuring the drying effect of the alumina ceramic fine powder. On the other hand, the rotating rod 13 drives the transmission rod 14 to rotate through the cooperation of the limit block 213 and the limit groove 212. When the transmission rod 14 rotates to the position of the first arc plate 42, the transmission rod 14 will squeeze the first arc plate 42 through the first extrusion block 41 during the self-rotation process. The first arc plate 42 is squeezed by the first support rod 43. The first baffle plate 44 is driven to move horizontally, and the first baffle plate 44 drives the first sealing plate 47 to move horizontally through the first slide plate 46, so that the exhaust port 7 is in an open state. With the rotation and circular motion of the transmission rod 14, the degree of extrusion of the first extrusion block 41 on the first arc plate 42 is reduced, and the first baffle plate 44 drives the first sealing plate 47 to automatically reset, so that the first sealing plate 47 can seal the exhaust port 7. This cycle is repeated, so that the exhaust port 7 is intermittently opened, and the water vapor generated during the drying process of the alumina ceramic fine powder can be discharged from the exhaust port 7 in time, avoiding the phenomenon that the water vapor generated during the drying process of the alumina ceramic fine powder remains in the storage tank 1, causing the alumina ceramic fine powder to be damp again, and there is no need to manually open the cover body, which saves energy. The invention can save manpower and ensure the sealing performance between the cover body and the feed hopper 6. In addition, the alumina ceramic powder can be filtered through the mesh plate 410 inside the exhaust port 7, and the water vapor passes through the mesh holes and is discharged directly from the exhaust port 7, and the alumina ceramic powder wrapped in the water vapor is filtered at the bottom of the mesh plate 410, which effectively avoids the phenomenon that the alumina ceramic powder is discharged to the outside of the storage tank 1 through the exhaust port 7 during the drying process, reduces the loss of alumina ceramic powder, and reduces the cost. In addition, the reciprocating motion of the first sealing plate 47 will also drive the trapezoidal block 48 to reciprocate. The trapezoidal block 48 will squeeze the protrusion 49 through its inclined surface while moving, so that the mesh plate 410 moves downward. When the trapezoidal block 48 no longer squeezes the protrusion 49,The mesh plate 410 automatically resets and moves upward, and the mesh plate 410 can vibrate up and down continuously in such a reciprocating cycle, thereby shaking off the alumina ceramic fine powder adsorbed on the bottom of the mesh plate 410 into the storage tank 1;

[0052] When alumina ceramic fine powder is needed, the push rod 24 is driven downward by the push block 27, and the push rod 24 drives the magnetic ring 22 downward through the connecting plate 23, so that the magnetic ring 22 and the magnet 21 repel each other and drive the transmission rod 14 to move downward, and the transmission rod 14 drives the first extrusion block 41 and the second extrusion block 51 to move downward. When the first extrusion block 41 and the first arc plate 42 are misaligned and the second extrusion block 51 and the second arc plate 52 are located on the same horizontal plane, the positioning pin 29 automatically enters the positioning groove 28. The second arc plate 52 is squeezed by the second squeezing block 51 during the self-rotation of the transmission rod 14, and the second arc plate 52 drives the second baffle plate 54 to move horizontally through the second support rod 53, and the second baffle plate 54 drives the second sealing plate 57 to move horizontally through the second slide plate 56, so that the discharge port 8 is in an open state. The rotation and circular motion of the second extrusion block 51 reduce the extrusion degree of the second arc plate 52, and the second baffle 54 drives the second sealing plate 57 to automatically reset, so that the second sealing plate 57 can block the discharge port 8, and this cycle is repeated, so that the discharge port 8 can be opened intermittently, thereby achieving the purpose of automatic discharge, and the alumina ceramic fine powder can be taken out from the storage tank 1 without manually opening the cover body, thereby ensuring the sealing performance between the cover body and the feed hopper 6, and avoiding the alumina ceramic fine powder being damp or contaminated when the staff opens the cover body for a long time. At this time, the first extrusion block 41 is misaligned with the first arc plate 42. At this time, no matter how the transmission rod 14 rotates, the first extrusion block 41 cannot squeeze the first arc plate 42, and the first arc plate 42 is always in the initial position. The first sealing plate 47 always seals the exhaust port 7, thereby avoiding the phenomenon that moisture in the air of the alumina ceramic fine powder enters the storage tank 1 through the exhaust port 7 during the discharge process, thereby ensuring the dryness of the alumina ceramic fine powder.
