Description

[0002] Industrial alumina powder is made from bauxite and diaspore. For alumina with high purity requirements, it is generally prepared by chemical methods. When storing existing alumina powder, it is usually heated and dried to evaporate the moisture in the alumina powder and prevent the alumina powder from deteriorating in the storage tank.

[0003] At present, the heat is mainly conducted to the alumina powder through the inner wall of the storage box for heating. Since the alumina powder in the middle of the storage box is relatively far away from the inner wall of the storage box, the alumina powder in the middle of the storage box cannot be fully heated, resulting in uneven heating of the alumina powder in the storage box, which in turn makes the drying effect of the alumina powder poor, and the alumina powder is prone to agglomeration and caking during storage. When the alumina powder is taken out from the discharge port, due to the large cohesive force between the powdered materials, the alumina powder is prone to blockage in the discharge port, and the alumina powder cannot be automatically discharged. The discharge port needs to be manually unblocked, and the use effect is poor. Summary of the invention

DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3The figure is a structural diagram of an alumina powder storage device provided by an embodiment of the present invention, comprising a box body 1, a feeding port is arranged at the top of the box body 1, an end cover 11 is arranged on the surface of the feeding port, a plurality of groups of guide pipes 12 are arranged on the bottom wall of the box body 1, a sealing cover 121 is spirally installed on the bottom end of the guide pipe 12, support legs 13 are fixedly installed around the bottom wall of the box body 1, a transmission column 2 is rotatably installed between the top wall and the bottom wall of the box body 1, the bottom end of the transmission column 2 extends to the outside of the box body 1 and is connected to a first motor 21, and the inner cavity of the box body 1 is provided with a first motor 21 connected to the first motor 21. The feeding mechanism 3 cooperates with the transmission column 2, and the feeding mechanism 3 includes a vertical feeding component 31 and a horizontal feeding component 32. The vertical feeding component 31 is located outside the transmission column 2. The vertical feeding component 31 is used to transport the aluminum oxide powder at different depths in the box body 1 upward to the top of the box body 1. The horizontal feeding component 32 is located in the inner cavity of the box body 1 and is connected to the vertical feeding component 31. The horizontal feeding component 32 is used to transport the aluminum oxide powder at different radii in the inner cavity of the box body 1 toward the transmission column 2. The guide pipe 12 is provided with a feeding mechanism 5. The feeding mechanism 5 includes a guide rod 51 and a positioning assembly 52. ​​The guide rod 51 is provided with multiple groups. The positioning assembly 52 is located in the guide pipe 12 and is connected to the guide rod 51. When the alumina powder falls in the guide pipe 12, the positioning assembly 52 controls the guide rod 51 to reciprocate in the guide pipe 12 along the vertical direction. A sieve plate 6 is fixedly installed on the top of the box body 1. The surface of the sieve plate 6 is provided with evenly distributed meshes 61. A drying mechanism 7 is provided on the top of the box body 1 above the sieve plate 6. The drying mechanism 7 includes a blowing assembly 7. 1 and a material spreading component 72, the blowing component 71 is located at the top of the box body 1 and is connected to the transmission column 2, the blowing component 71 is used to speed up the air flow speed at the top of the box body 1, the material spreading component 72 includes a brush 721, a support part 722 and a rotating part 723, the support part 722 is located on the surface of the sieve plate 6 and is connected to the brush 721, the rotating part 723 is located above the sieve plate 6 and is connected to the support part 722, and the rotating part 723 controls the brush 721 to continuously rotate on the surface of the sieve plate 6 by cooperating with the support part 722.

[0031] Initially, the sealing cover 121 seals the guide pipe 12, the end cover 11 is opened, and the alumina powder to be stored is fed into the inner cavity of the box body 1 through the feeding port. The alumina powder passes through the mesh 61 and further falls to the bottom of the box body 1. The feeding is continued, and the height of the alumina powder in the inner cavity of the box body 1 continues to increase. When it is necessary to dry the alumina powder at a corresponding depth in the inner cavity of the box body 1, the first motor 21 drives the transmission column 2 to rotate, and the horizontal feeding component 32 can control the alumina powder at a corresponding depth in the inner cavity of the box body 1 to move toward the central axis of the box body 1. When the alumina powder moves to the vicinity of the central axis of the box body 1, the vertical feeding component 31 can automatically transport the alumina powder at the corresponding depth vertically upward to the box body 1. The aluminum oxide powder is fed to the inner top and further falls to the surface of the sieve plate 6. After the aluminum oxide powder falls to the surface of the sieve plate 6, the support part 722 cooperates with the rotating part 723 to control multiple groups of brushes 721 to rotate on the surface of the sieve plate 6. The brushes 721 can spread the aluminum oxide powder evenly. The blowing component 71 can speed up the air flow speed on the surface of the sieve plate 6, and then the evenly spread aluminum oxide powder can be fully and efficiently dried. The aluminum oxide powder after blowing and drying passes through the mesh 61 and falls below the sieve plate 6. The horizontal feeding component 32 cooperates with the vertical feeding component 31 to accurately convey the aluminum oxide powder at different depths in the inner cavity of the box 1 upward, and then it can be efficiently blown and dried. During the entire conveying and spreading process on the surface of the sieve plate 6, the agglomeration of aluminum oxide powder can be effectively avoided, and the quality of aluminum oxide powder can be improved.

[0032] When the alumina powder in the inner cavity of the box body 1 needs to be taken out, the sealing cover 121 is opened, and the alumina powder at the bottom of the box body 1 can automatically fall to the outside of the box body 1 through the drain pipe 12. When the alumina powder falls in the drain pipe 12, the positioning assembly 52 can control the multiple groups of guide rods 51 to move back and forth in the vertical direction in the drain pipe 12. When the guide rods 51 move in the vertical direction, the cohesion between the alumina powders can be effectively destroyed, thereby controlling the alumina powder at the bottom of the box body 1 to continue to fall, and effectively avoiding the blockage of the alumina powder in the drain pipe 12.

[0033] like Figure 2 , Figure 3 , Figure 4 , Figure 8 As shown, as a preferred embodiment of the present invention, the vertical feeding assembly 31 includes a vertical cylinder 311 fixedly installed at the bottom of the box body 1, the vertical cylinder 311 is sleeved on the outside of the transmission column 2, an opening 312 is provided at the top of the vertical cylinder 311, and a plurality of groups of feed ports 314 are provided on the side wall of the vertical cylinder 311 along the vertical direction, and a first spiral blade 313 located in the vertical cylinder 311 is fixedly installed on the surface of the transmission column 2.

[0034] During use, when it is necessary to dry the alumina powder at the corresponding depth in the inner cavity of the box body 1, the horizontal feeding assembly 32 moves the alumina powder at different radial positions at the corresponding depth of the box body 1 toward the vertical cylinder 311, and further transports the alumina powder to the inside of the vertical cylinder 311 through the feed port 314, and the first motor 21 drives the transmission column 2 to rotate and then drives the first spiral blade 313 to rotate synchronously in the vertical cylinder 311. The rotating first spiral blade 313 can push the alumina powder in the vertical cylinder 311 to move vertically upward, and further discharge the alumina powder through the opening 312 at the top, and the alumina powder passes through the opening 312 and falls onto the surface of the sieve plate 6.

[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig.10 As shown, as a preferred embodiment of the present invention, the horizontal feeding assembly 32 includes a plurality of transverse cylinders 321 fixedly installed on the inner wall of the box body 1, the end of the transverse cylinder 321 away from the side wall of the box body 1 is connected to the vertical cylinder 311, the transverse cylinder 321 is connected to the feed port 314, a rotating shaft 322 is rotatably installed in the transverse cylinder 321, a second spiral blade 324 located in the transverse cylinder 321 is fixedly installed on the surface of the rotating shaft 322, a feed groove 323 is opened on the surface of the transverse cylinder 321, and the end of the rotating shaft 322 away from the vertical cylinder 311 extends to the outside of the box body 1 and is connected to a driving member 4.

[0036] When it is necessary to dry the alumina powder at the corresponding depth of the inner cavity of the box body 1, the driving member 4 controls the rotating shaft 322 at the corresponding depth of the inner cavity of the box body 1 to rotate in the horizontal cylinder 321, and the rotating shaft 322 drives the second spiral blade 324 to rotate synchronously in the horizontal cylinder 321. The alumina powder at the corresponding depth of the inner cavity of the box body 1 passes through the feed trough 323 and falls into the horizontal cylinder 321. The rotation of the second spiral blade 324 can push the alumina powder in the horizontal cylinder 321 to move toward the vertical cylinder 311, and further transport the alumina powder in the horizontal cylinder 321 to the feed port 314 and then fall into the inner cavity of the vertical cylinder 311. The rotating first spiral blade 313 can push the alumina powder in the vertical cylinder 311 to move vertically upward, and further discharge the alumina powder through the opening 312 at the top. The second spiral blade 324 can continuously transport the alumina powder in the horizontal cylinder 321 to the vertical cylinder 311.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig.10As shown, as a preferred embodiment of the present invention, the driving member 4 includes a shell 41 arranged on the side wall of the box body 1, a second motor 42 is fixedly installed in the shell 41, a card joint 44 is fixedly installed at one end of the rotating shaft 322 located outside the box body 1, and the output shaft of the second motor 42 is provided with a card groove 43 that cooperates with the card joint 44.

[0038] When in use, the shell 41 is installed on the outer wall of the box body 1, the clamping groove 43 on the surface of the output shaft of the second motor 42 and the clamping joint 44 are engaged with each other, and the second motor 42 is started, and the second motor 42 drives the rotating shaft 322 to rotate.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig.10 As shown, as a preferred embodiment of the present invention, the driving member 4 also includes a positioning bolt 45 detachably mounted on the surface of the shell 41 , and the side wall of the box body 1 is provided with a positioning screw hole 46 located outside the rotating shaft 322 and cooperating with the positioning bolt 45 .

[0040] When in use, the housing 41 and the second motor 42 can be conveniently installed and removed on the outer wall of the box body 1 by the cooperation of the positioning bolts 45 and the positioning screw holes 46. When it is not necessary to dry the aluminum oxide powder in the inner cavity of the box body 1, the housing 41 and the second motor 42 are stored separately, and the clamping joint 44 is exposed at the outer wall of the box body 1. When it is necessary to dry the aluminum oxide powder at a specific height in the inner cavity of the box body 1, the housing 41 can be installed at the corresponding height of the outer wall of the box body 1 by the cooperation of the positioning bolts 45 and the positioning screw holes 46, so that the second motor 42 drives the rotating shaft 322 at the corresponding position to rotate.

[0041] like Figure 2 , Figure 5 , Figure 7 As shown, as a preferred embodiment of the present invention, the positioning assembly 52 includes a plurality of brackets 521 fixedly installed on the inner wall of the guide tube 12, the plurality of brackets 521 are jointly fixedly installed with two groups of bearing blocks 522 distributed in the vertical direction, the two groups of bearing blocks 522 are jointly slidably installed with a telescopic rod 523, the plurality of guide rods 51 are evenly distributed on the surface of the telescopic rod 523, a limit plate 524 located between the two groups of bearing blocks 522 is fixedly installed on the surface of the telescopic rod 523, a reset spring 525 is fixedly installed on the surface of the lower bearing block 522, the reset spring 525 surrounds the outer side of the telescopic rod 523 and is connected to the limit plate 524, and a baffle 526 is provided at the bottom end of the telescopic rod 523.

[0042] The two groups of bearing blocks 522 position the telescopic rod 523, and the return spring 525 cooperates with the limit plate 524 to support the telescopic rod 523. When the aluminum oxide powder in the inner cavity of the box body 1 needs to be taken out, the sealing cover 121 is opened, and the aluminum oxide powder at the bottom of the box body 1 can automatically fall to the outside of the box body 1 through the guide pipe 12. When the aluminum oxide powder falls in the guide pipe 12, the aluminum oxide powder will fall to the surface of the baffle 526 and generate a vertical downward impact force on the baffle 526. The baffle 526 drives the telescopic rod 523 to move downward synchronously in the guide pipe 12. At this time, the telescopic rod 523 23 drives multiple groups of guide rods 51 to move downward synchronously. The telescopic rod 523 and the limit plate 524 will squeeze the return spring 525 when they move downward. When the telescopic rod 523 moves downward to the lowest position, the elastic force of the return spring 525 reaches the maximum and can push the limit plate 524 and the telescopic rod 523 to move upward again. At this time, the telescopic rod 523 drives multiple groups of guide rods 51 to move upward synchronously. This cycle is repeated, and multiple groups of guide rods 51 move back and forth in the vertical direction, which can effectively destroy the cohesion between the aluminum oxide powder in the guide pipe 12, so that the aluminum oxide powder continues to fall from the guide pipe 12.

[0043] like Figure 2 , Figure 5 , Figure 7 As shown, as a preferred embodiment of the present invention, a through hole 528 is opened on the surface of the sealing cover 121, and the bottom end of the telescopic rod 523 extends to the outside of the guide pipe 12 through the through hole 528, and the bottom end of the telescopic rod 523 is provided with an external thread, and the surface of the baffle 526 is provided with a fixing screw hole 527 that cooperates with the bottom end of the telescopic rod 523.

[0044] When in use, the baffle 526 can be easily installed and disassembled at the bottom end of the telescopic rod 523 through the cooperation between the external thread and the fixing screw hole 527. Initially, the telescopic rod 523 passes through the through hole 528, and the through hole 528 is in a sealed state. When the alumina powder needs to be drained, the baffle 526 is removed from the bottom end of the telescopic rod 523, and then the sealing cover 121 can be easily removed from the bottom end of the drain pipe 12, and then the baffle 526 is installed at the bottom end of the telescopic rod 523. When the alumina powder falls in the drain pipe 12, the alumina powder will fall to the surface of the baffle 526 and generate a vertical downward impact force on the baffle 526.

[0045] like Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig. 9As shown, as a preferred embodiment of the present invention, the blowing assembly 71 includes a side panel 713 fixedly installed on the inner top wall of the box body 1, and the inner wall of the box body 1 and the side panel 713 are jointly rotatably installed with a first bearing rod 711, and a plurality of groups of evenly distributed fan blades 712 are arranged on the surface of the first bearing rod 711, and an active bevel gear plate 714 is fixedly installed on the surface of the transmission column 2, and a driven bevel gear plate 715 is fixedly installed on the surface of the first bearing rod 711, and the driven bevel gear plate 715 is meshingly connected with the active bevel gear plate 714, and a ventilation hole is opened on the side wall of the box body 1 above the screen plate 6, and the ventilation holes are distributed obliquely downward from the inside of the box body 1 toward the outside of the box body 1.

[0046] Alumina powder passes through the opening 312 and falls onto the surface of the screen disc 6. The first motor 21 drives the transmission column 2 to rotate and then drives the active bevel gear disc 714 to rotate synchronously. The active bevel gear disc 714 engages with the driven bevel gear disc 715 for transmission, and then drives the first bearing rod 711 to rotate. The first bearing rod 711 drives the fan blades 712 to rotate above the screen disc 6. The fan blades 712 can accelerate the air flow speed on the surface of the screen disc 6 when rotating, and then the alumina powder on the surface of the screen disc 6 can be efficiently blown and dried.

[0047] like Figure 2 , Figure 3 , Figure 4 , Fig. 9 As shown, as a preferred embodiment of the present invention, the support portion 722 includes a fixed ring 7221 rotatably mounted on the surface of the screen plate 6, and the side wall of the fixed ring 7221 is provided with a second bearing rod 7222 located above the screen plate 6, and multiple groups of brushes 721 are evenly distributed on the surface of the second bearing rod 7222.

[0048] The fixing ring 7221 and the second bearing rod 7222 cooperate with each other to support and position the multiple groups of brushes 721. The aluminum oxide powder passes through the opening 312 and falls on the surface of the sieve material plate 6. The rotating part 723 controls the fixing ring 7221 to rotate on the surface of the sieve material plate 6. The fixing ring 7221 drives the second bearing rod 7222 to rotate synchronously on the surface of the sieve material plate 6. The second bearing rod 7222 drives the brush 721 to rotate synchronously. The brush 721 can spread the aluminum oxide powder falling on the surface of the sieve material plate 6, so that the aluminum oxide powder is spread evenly, which is convenient for blowing and drying. And the aluminum oxide powder that has agglomerated can be dispersed.

[0049] like Figure 2 , Figure 3 , Figure 4 , Fig. 9As shown, as a preferred embodiment of the present invention, the rotating part 723 includes a transmission gear disc 7231 fixedly installed on the surface of the first bearing rod 711, and a fixed gear disc 7232 meshingly connected with the transmission gear disc 7231 is rotatably installed on the inner wall of the box body 1, and a toothed ring 7233 is arranged on the surface of the fixed ring 7221, and the toothed ring 7233 is meshingly connected with the fixed gear disc 7232.

[0050] When in use, the first bearing rod 711 drives the transmission gear plate 7231 to rotate. The transmission gear plate 7231 can drive the fixed gear plate 7232 to rotate on the inner wall of the box body 1 by meshing with the fixed gear plate 7232. The fixed gear plate 7232 meshes with the gear ring 7233 to drive the fixed ring 7221 to rotate on the surface of the screening plate 6.

[0051] like Figure 2 , Figure 3 , Figure 4 , Fig. 9 As shown, as a preferred embodiment of the present invention, an annular guide groove 8 is provided on the surface of the fixing ring 7221, and a guide ring 9 is rotatably installed in the guide groove 8. The guide ring 9 extends to the outside of the guide groove 8 and is connected to the fixing ring 7221.

[0052] The guide ring 9 rotates in the guide groove 8, which can effectively improve the stability of the fixing ring 7221 when it rotates on the surface of the screening plate 6.

[0053] The working principle of the present invention is as follows: initially, the sealing cover 121 seals the guide pipe 12, the end cover 11 is opened, and the alumina powder to be stored is fed into the inner cavity of the box body 1 through the feeding port. The alumina powder passes through the mesh 61 and further falls to the bottom of the box body 1. The feeding is continued, and the height of the alumina powder in the inner cavity of the box body 1 continues to increase. When the alumina powder at a corresponding depth in the inner cavity of the box body 1 needs to be dried, the housing 41 can be installed at a corresponding height of the outer wall of the box body 1 through the cooperation of the positioning bolts 45 and the positioning screw holes 46. The clamping groove 43 on the surface of the output shaft of the second motor 42 is connected with the clamping groove 43 on the output shaft of the second motor 42. The heads 44 are engaged with each other, and the second motor 42 is started. The second motor 42 drives the rotating shaft 322 to rotate. The rotating shaft 322 at the corresponding depth of the inner cavity of the box body 1 rotates in the horizontal cylinder 321. The rotating shaft 322 drives the second spiral blade 324 to rotate synchronously in the horizontal cylinder 321. The aluminum oxide powder at the corresponding depth of the inner cavity of the box body 1 passes through the feed trough 323 and falls into the horizontal cylinder 321. The rotation of the second spiral blade 324 can push the aluminum oxide powder in the horizontal cylinder 321 to move toward the vertical cylinder 311, and further transport the aluminum oxide powder in the horizontal cylinder 321 to the feed port 314 and then fall into the inner cavity of the vertical cylinder 311. The first motor 21 drives the transmission column 2 to rotate and then drives the first spiral blade 313 to rotate synchronously in the vertical cylinder 311. The rotating first spiral blade 313 can push the aluminum oxide powder in the vertical cylinder 311 to move vertically upward, and further discharge the aluminum oxide powder through the opening 312 at the top. The aluminum oxide powder passes through the opening 312 and falls onto the surface of the sieve plate 6.

[0054] The first motor 21 drives the transmission column 2 to rotate and then drives the active beveled toothed disc 714 to rotate synchronously. The active beveled toothed disc 714 is meshed with the driven beveled toothed disc 715 for transmission, and then can drive the first bearing rod 711 to rotate. The first bearing rod 711 drives the fan blades 712 to rotate above the sieve plate 6. The fan blades 712 can accelerate the air flow speed on the surface of the sieve plate 6 when rotating, and then can perform efficient air drying treatment on the surface of the sieve plate 6. The first bearing rod 711 drives the transmission toothed disc 7231 to rotate. The transmission toothed disc 7231 can drive the fixed toothed disc 7232 to rotate at the inner wall of the box body 1 by meshing with the fixed toothed disc 7232. The fixed toothed disc 7232 is meshed with the gear ring 7233 for transmission, and can drive the fixed ring 7221 to rotate on the surface of the sieve plate 6. The fixing ring 7221 drives the second bearing rod 7222 to rotate synchronously on the surface of the sieve material plate 6, and the second bearing rod 7222 drives the brush 721 to rotate synchronously, and the brush 721 can spread the aluminum oxide powder falling on the surface of the sieve material plate 6, so that the aluminum oxide powder is spread evenly, which is convenient for blowing and drying. And the aluminum oxide powder that has agglomerated can be dispersed.

[0055] When the aluminum oxide powder in the inner cavity of the box body 1 needs to be taken out, the sealing cover 121 is opened, and the aluminum oxide powder at the bottom of the box body 1 can automatically fall to the outside of the box body 1 through the guide pipe 12. When the aluminum oxide powder falls in the guide pipe 12, the aluminum oxide powder will fall on the surface of the baffle 526 and generate a vertical downward impact force on the baffle 526. The baffle 526 drives the telescopic rod 523 to move downward synchronously in the guide pipe 12. At this time, the telescopic rod 523 drives multiple groups of guide rods 51 to move downward synchronously. The telescopic rod 523 and the limit plate When 524 moves downward, it will squeeze the return spring 525. When the telescopic rod 523 moves downward to the lowest position, the elastic force of the return spring 525 reaches the maximum and can push the limit plate 524 and the telescopic rod 523 to move upward again. At this time, the telescopic rod 523 drives multiple groups of guide rods 51 to move upward synchronously. This cycle is repeated, and multiple groups of guide rods 51 move back and forth in the vertical direction, which can effectively destroy the cohesion between the aluminum oxide powder in the guide tube 12, so that the aluminum oxide powder continues to fall from the guide tube 12.

[0056] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
