Description

Technical Field

[0001] The present application relates to the technical field of storage equipment, and in particular to a metal powder storage device. Background Art

[0002] In the field of industrial production and scientific research related to metal powder, the storage of metal powder has always been a crucial and challenging link. With the rapid development of modern industry, metal powder, as the core raw material of many key industries, has been applied in many important fields such as powder metallurgy, 3D printing, electronic material preparation, and high-end coating production. Metal powder is generally placed in a storage bin. Due to its fine particle size and high surface energy, metal powder is very easy to interact with the surrounding environment. Once the moisture in the air comes into contact with the metal powder, it will cause deliquescence, forming a thin liquid film on the surface of the powder particles, resulting in strong adhesion between the particles, which in turn causes agglomeration and agglomeration, seriously damaging the fluidity and uniformity of the powder, which not only affects the normal use of the metal powder, but also causes problems such as discharge blockage and unsmooth discharge.

[0003] For example, a Chinese patent document with a publication number of CN108557290B discloses a silo arch breaking device and a feeder using the device, comprising a silo, a driving device, a rotating spindle, and an arch breaking spiral; the rotating spindle is vertically arranged in the silo; the driving device is connected to the rotating spindle in a transmission manner and drives the rotating spindle to rotate about its own axis; the arch breaking spiral is transversely fixed on the rotating spindle, and a spiral rising member is provided at one end of the arch breaking spiral away from the rotating spindle; the upper surface of the spiral rising member gradually rises from the front end to the rear end thereof; a bottom plate is provided at the bottom of the silo, an inward flange is provided at the lower end of the silo wall of the silo, the bottom plate is fixedly supported on the silo, and a discharge gap is provided between the bottom plate and the flange; the lower end of the rotating spindle is pivotally connected to the bottom plate; a bottom arch breaking rod rotating with the rotating spindle is fixedly provided at the rotating spindle near the bottom plate, the rotating spindle is driven to rotate by a motor, and the rotating spindle rotates to drive the bottom arch breaking rod to rotate close to the silo wall, and then the arch breaking rod is used to break the material at the bottom.

[0004] In the above-mentioned related technologies, the coal powder is rotated and discharged by installing a motor at the bottom of the hopper. Although the coal powder can be discharged well, when the material in the storage bin is not discharged for a long time, the material at the discharge port may clump. When the material needs to be discharged, the motor needs to output a large enough torque to drive the scraper to rotate. When the rotating scraper is stuck by the block material, it will cause the motor to burn out. Summary of the invention

[0005] The present application provides a metal powder storage device, aiming to solve the problem of how to increase the service life of a motor in the related art.

[0006] A metal powder storage device provided by this application adopts the following technical solution: A metal powder storage device includes a silo, an arch-breaking rod arranged in the silo, and a driving component. The arch-breaking rod is attached to the inner wall of the conical discharge pipe. The driving component includes a driving motor fixed on the silo and a driving ring fixed on the driving motor. The driving ring is connected to the arch-breaking rod. An installation rod is arranged on the driving ring, and a first connection component for connecting with the installation rod is arranged on the arch-breaking rod. The first connection component is set as a universal joint. The driving ring and the arch-breaking rod are soft-connected through the universal joint. A first arch-breaking component and a plurality of second arch-breaking components for breaking up agglomerated materials are arranged on the arch-breaking rod; when the arch-breaking rod encounters agglomeration and is blocked during the rotation direction, under the action of the universal joint, the moving speed of the upper end of the arch-breaking rod becomes slower, so that the arch-breaking rod is inclined during the moving process, and the upper end and the lower end of the arch-breaking rod are not in the same plane.

[0007] By adopting the above technical solution, when the silo has not discharged materials for a long time, the materials in the silo will agglomerate. When the agglomerated materials jam the arch-breaking rod and the arch-breaking rod cannot rotate, a large force is required for the driving motor to drive the arch-breaking rod to rotate, which may cause the driving motor to burn out, thereby reducing the service life of the driving motor; when the driving motor drives the driving ring to rotate, in the case where the arch-breaking rod is stuck and cannot rotate, under the action of the universal joint, the moving speed of the lower end of the arch-breaking rod is faster, and the moving speed of the upper end is slower. Then, a gap will appear between the arch-breaking rod and the inner wall of the discharge pipe, and the agglomerated materials are in this gap, playing a role of avoidance. At this time, the angle of the arch-breaking rod will change during the rotation process, so that the arch-breaking rod no longer adheres to the inner wall of the discharge pipe, and at the same time, the arch-breaking rod and the agglomerated materials no longer directly contact, thereby reducing the resistance when the arch-breaking rod rotates. Since the universal joint can rotate in different directions, when there are obstacles in different directions, the arch-breaking rod can move along the position where it does not contact the agglomerated materials, and then it can still break the arch of the materials when passing through the position where it does not contact the agglomerated materials, so as to reduce the torque when the motor rotates and improve the service life of the motor.

[0008] Optionally, the universal joint includes a first mounting bracket rotatably connected to the mounting rod, a first rotating shaft rotatably connected to the first mounting bracket, a second rotating shaft fixed on the first rotating shaft, and a second mounting bracket rotatably connected to the second rotating shaft. The first rotating shaft and the second rotating shaft are perpendicularly arranged.

[0009] By adopting the above technical solution, since the first mounting bracket rotates on the mounting rod, at this time, the arch-breaking rod can rotate around the rotation axis of the first mounting bracket. Under the action of the first mounting shaft, the second mounting shaft, and the second mounting bracket, the arch-breaking rod can rotate in different directions, thereby reducing the resistance when the arch-breaking rod moves.

[0010] Optionally, torsion springs are provided on the first mounting bracket, the second mounting bracket, the first rotating shaft and the second rotating shaft. One end of the torsion spring on the first rotating shaft is fixed to the first rotating shaft, and the other end is fixed to the second mounting bracket. One end of the torsion spring on the second rotating shaft is fixed to the second rotating shaft, and the other end is fixed to the first mounting bracket. One end of the torsion spring on the second mounting bracket is fixed to the arch-breaking rod, and the other end is fixed to the second mounting bracket.

[0011] By adopting the above technical solution, when the arch-breaking rod rotates, each torsion spring will be in a state of storing energy, and then there will be a tendency to drive the arch-breaking rod to move in the reverse direction. Under the action of each torsion spring, the arch-breaking rod is pushed against the inner wall of the discharge pipe, which can better extrude the material, improve the dispersing effect of the caked material, and make the material discharging effect better.

[0012] Optionally, a first dispersing assembly for dispersing the caked material is provided on the arch-breaking rod. The first dispersing assembly includes a dispersing shaft rotatably connected to the arch-breaking rod, a plurality of first dispersing rods fixed to the dispersing shaft, and a first dispersing motor fixed to the arch-breaking rod. The output shaft of the first dispersing motor is fixedly connected to the dispersing shaft.

[0013] By adopting the above technical solution, while the driving assembly drives the arch-breaking rod to rotate, the first dispersing motor rotates, driving the dispersing shaft and the plurality of first dispersing rods fixed to the dispersing shaft to rotate, and then the caked material is dispersed by the first dispersing rods. After dispersion, it is convenient for the arch-breaking rod to rotate, so as to achieve the purpose of reducing the resistance of the arch-breaking rod, and further improve the service life of the driving assembly.

[0014] Optionally, a plurality of second dispersing assemblies for dispersing the caked material are provided on the arch-breaking rod; the second dispersing assembly includes a dispersing disk provided on the arch-breaking rod and a dispersing member provided on the dispersing disk. The dispersing member protrudes from the surface of the arch-breaking rod, and a control assembly for driving a plurality of dispersing disks to rotate simultaneously is provided on the arch-breaking rod.

[0015] By adopting the above technical solution, the dispersing members on the dispersing disks protrude from the surface of the arch-breaking rod, and then the control assembly drives the dispersing disks and the dispersing members to rotate. During the rotation of the dispersing members, the material will be dispersed, and then the resistance during the rotation of the arch-breaking rod can be reduced.

[0016] Optionally, a plurality of dispersing disks are provided, and the plurality of dispersing disks are evenly spaced along the length direction of the arch-breaking rod.

[0017] Optionally, the control assembly includes a control toothed belt wound around a plurality of dispersing disks at the same time, a plurality of control grooves provided on the dispersing disks, and a control motor fixed inside the arch-breaking rod. The output shaft of the control motor is connected to one of the dispersing disks, and the control toothed belt cooperates with the control grooves on the dispersing disks.

[0018] Optionally, the dispersing member includes a plurality of dispersing pieces with a mounting shaft rotatably connected to the dispersing disk and fixed to the rotating shaft, and the dispersing pieces protrude from the surface of the dispersing disk. A detection component for detecting the position of the dispersing disk is provided on the dispersing disk.

[0019] Optionally, the detection component includes a rotation speed sensor fixed on the dispersing disk and a controller provided on the arch-breaking rod, and the controller is used to connect to the first dispersing motor, the control motor, and the driving motor.

[0020] Optionally, a plurality of dispersing teeth are fixedly installed at both ends of the dispersing piece.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the driving motor drives the driving ring to rotate, in the case where the arch-breaking rod is stuck and cannot rotate, under the action of the universal joint, the lower end of the arch-breaking rod moves faster and the upper end moves slower. Then, a gap will appear between the arch-breaking rod and the inner wall of the discharge pipe, and the agglomerated material is in this gap, playing a role of avoidance. At this time, during the rotation process, the angle of the arch-breaking rod will be changed, so that the arch-breaking rod no longer fits the inner wall of the discharge pipe, thereby reducing the resistance when the arch-breaking rod rotates, reducing the torque when the motor rotates, and improving the service life of the motor.

[0022] 2. When the arch-breaking rod rotates, each torsion spring will be in a state of storing energy, and then there is a tendency to drive the arch-breaking rod to move in the reverse direction. Under the action of each torsion spring, the arch-breaking rod is pushed against the inner wall of the discharge pipe, which can better squeeze the material, improve the dispersing effect of the agglomerated material, and make the material discharging effect better.

Detailed implementation manners

[0034] The following is a further detailed description of the present application in conjunction with Figures 1-10 to further illustrate the present application in detail.

[0035] An embodiment of the present application discloses a metal powder storage device. Referring to Figures 1 to 5 , a metal powder storage device includes a frame 01 and a silo 02 provided on the frame 01. A discharge pipe 03 is provided at the bottom of the silo 02. The discharge pipe 03 is provided with a conical structure. At the same time, a drive assembly 1 is provided on the discharge pipe 03. A first connection assembly 2 is provided on the drive assembly 1, and an arch-breaking rod 04 is provided on the first connection assembly 2. The arch-breaking rod 04 abuts against the inner wall of the discharge pipe 03. The drive assembly 1 is used to drive the arch-breaking rod 04 to rotate, so that the arch-breaking rod 04 can disperse the agglomerated materials inside, reduce the phenomenon of arching of the materials in the discharge pipe 03, and thus facilitate the falling of the materials from the discharge pipe 03. In addition, a first dispersing assembly 3, a second dispersing assembly 4 and a detection assembly 7 for detecting the state of the materials in the discharge pipe 03 are provided on the arch-breaking rod 04. The first dispersing assembly 3 and the second dispersing assembly 4 are used to disperse the agglomerated materials and reduce the resistance encountered when the arch-breaking rod 04 moves.

[0036] Referring to Figures 1 to 5, the driving assembly 1 includes a driving motor 11 fixed on the discharge pipe 03, a driving ring 12 fixed on the driving motor 11, and a mounting rod 13 fixed on the driving ring 12. An installation groove is formed on the discharge pipe 03, and the driving ring 12 is snap-fitted in the installation groove and rotates in the installation groove. The first connection assembly 2 is arranged on the mounting rod 13. The driving motor 11 drives the driving ring 12 and the mounting rod 13 to rotate, the mounting rod 13 drives the first connection assembly 2 to rotate, and the first connection assembly 2 drives the arch-breaking rod 04 to rotate, so as to achieve the purpose of arch-breaking the material.

[0037] Refer to Figures 1 to 5 and Figure 9 and Figure 10 , the first connection assembly 2 is set as a universal joint 21. Under the action of the universal joint 21, when the arch-breaking rod 04 encounters agglomerates and is blocked during the rotation direction, the lower end of the arch-breaking rod 04 continues to rotate under the action of the driving motor 11. Due to the blockage of the agglomerated material, the moving speed of the upper end of the arch-breaking rod 04 becomes slower. At this time, the upper end of the arch-breaking rod 04 will move downward, then the arch-breaking rod 04 is in an inclined state, and the distance between the upper end and the lower end of the arch-breaking rod 04 becomes smaller. At this time, the height of the arch-breaking rod 04 becomes lower, and at the same time, the arch-breaking rod 04 no longer abuts against the inner wall of the discharge pipe 03, so as to achieve the purpose of changing the moving direction of the arch-breaking rod 04.

[0038] Since the moving speed of the upper end of the arch-breaking rod 04 is slow and the moving speed of the lower end is fast, at this time, the arch-breaking rod 04 no longer abuts against the inner wall of the discharge pipe 03, and the material in the discharge pipe 03 will be cut (as Figure 9 and Figure 10 shown), and then the material can be better and faster dispersed.

[0039] Refer to Figures 2 to 5 , the universal joint 21 includes a first mounting bracket 211 arranged on the mounting rod 13, a first rotating shaft 212 rotatably connected to the first mounting bracket 211, a second rotating shaft 213 fixed on the first rotating shaft 212, and a second mounting bracket 214 rotatably connected to the second rotating shaft 213. The first rotating shaft 212 and the second rotating shaft 213 are perpendicularly arranged; a rotating shaft 215 is fixedly installed on the first mounting bracket 211. The rotating shaft 215 is rotatably connected to the mounting rod 13, and a torsion spring 216 is sleeved on the rotating shaft 215. One end of the torsion spring 216 is fixed on the rotating shaft 215, and the other end is fixed on the mounting rod 13. Under the action of the torsion spring 216 on the first mounting bracket 211, the arch-breaking rod 04 can abut against the inner wall of the discharge pipe 03 when not stressed.

[0040] Refer to Figures 1 to 5, a rotating shaft 215 is also fixedly installed on the second mounting bracket 214. The rotating shaft 215 on the second mounting bracket 214 is rotatably connected to the arch-breaking rod 04, and a torsion spring 216 is sleeved on the rotating shaft 215 on the second mounting bracket 214. One end of the torsion spring 216 is fixed on the arch-breaking rod 04, and the other end is fixed on the second mounting bracket 214, which can reset the rotated arch-breaking rod 04; in addition, torsion springs 216 are sleeved on both the first rotating shaft 212 and the second rotating shaft 213. When the energy stored in the torsion spring 216 reaches a certain level, there will be a tendency to drive the arch-breaking rod 04 to reset in the reverse direction. Under the action of each torsion spring 216, the arch-breaking rod 04 will be pushed and abutted against the inner wall of the discharge pipe 03 in the initial state.

[0041] Refer to Figures 1 to 5 , a limiting block 06 is arranged on the rotating shaft 215, and at the same time, a limiting groove 05 is opened on the mounting rod 13. The limiting block 06 is slidably connected in the limiting groove 05. In this embodiment, the limiting groove 05 is not opened in a circle. Then, when the first mounting bracket 211 rotates, it can prevent the torsion spring 216 from being unable to reset the first mounting bracket 211 when the first mounting bracket 211 rotates one circle.

[0042] Refer to Figures 1 to 5 , the first dispersing assembly 3 includes a dispersing shaft 31 rotatably connected to the arch-breaking rod 04, a plurality of first dispersing rods 32 fixed on the dispersing shaft 31, and a first dispersing motor 33 fixed on the arch-breaking rod 04. The output shaft of the first dispersing motor 33 is fixedly connected to the dispersing shaft 31. When the first dispersing motor 33 rotates, it can drive the dispersing shaft 31 to rotate, and then drive the plurality of dispersing rods 32 to rotate through the dispersing shaft 31.

[0043] During the rotation of the arch-breaking rod 04, after the first dispersing motor 33 drives the first dispersing rods 32 to effectively disperse the agglomerated materials, the overall state of the materials becomes looser and easier to flow. In this case, the resistance encountered by the arch-breaking rod 04 during rotation will be significantly reduced; on the one hand, due to the loose state of the materials, the arch-breaking rod 04 does not need to spend too much effort to break the agglomerated structure of the materials, so it can complete its arch-breaking and stirring work more easily; not only improves the working efficiency of the arch-breaking rod 04, but also reduces the energy consumption caused by excessive resistance; on the other hand, the reduction of the resistance on the arch-breaking rod 04 also means that the driving assembly 1 does not need to bear too much load; when the load is reduced, the pressure and wear on each component inside the driving motor 11 will also be reduced accordingly, thereby prolonging the service life of the driving motor 11.

[0044] Refer to Figures 5 to 8, a placement groove is formed in the arch-breaking rod 04, and the second dispersing assembly 4 is arranged in the placement groove. The second dispersing assembly 4 includes a dispersing disk 41 rotatably connected to the arch-breaking rod 04 and a dispersing member 42 arranged on the dispersing disk 41. The surface of the dispersing disk 41 is flush with the surface of the arch-breaking rod 04, and the dispersing member 42 protrudes from the surface of the arch-breaking rod 04. A control assembly 6 for driving the dispersing disk 41 to rotate is arranged on the arch-breaking rod 04. When the dispersing disk 41 rotates, it drives the dispersing member 42 to rotate, and then during the movement of the arch-breaking rod 04, the caked material can be dispersed by the dispersing disk 41 and the dispersing member 42. A plurality of dispersing disks 41 are arranged on the arch-breaking rod 04, and the plurality of dispersing disks 41 are evenly spaced along the length direction of the arch-breaking rod 04, and the control assembly 6 is used to drive the plurality of dispersing disks 41 and the dispersing members 42 to rotate simultaneously, so that the effect of the second dispersing assembly 4 on dispersing the material is better.

[0045] Refer to Figures 5 to 8 , the dispersing member 42 includes a mounting shaft 421 rotatably connected to the dispersing disk 41 and a plurality of dispersing blades 422 fixed on the mounting shaft 421. In this embodiment, one end of the mounting shaft 421 is rotatably connected to the dispersing disk 41, and the other end is used for mounting the detection assembly 7, and the dispersing blades 422 protrude from the surface of the dispersing disk 41. The axis of the mounting shaft 421 is perpendicular to the axis of the dispersing disk 41, and the plurality of dispersing blades 422 are evenly spaced along the circumferential direction of the mounting shaft 421. Then when the control assembly 6 drives the dispersing disk 41 to rotate, the dispersing disk 41 can drive the mounting shaft 421 and the dispersing blades 422 arranged on the mounting shaft 421 to rotate around the axis of the dispersing disk 41, thereby achieving the purpose of dispersing the material. In addition, when there is material falling in the discharge pipe 03, the falling material can push the dispersing blade 422 to rotate around the axis of the mounting shaft 421, and at this time the dispersing disk 41 does not rotate.

[0046] In order to facilitate the dispersing blade 422 to disperse the material, a dispersing tooth 5 is fixedly installed at the end of the dispersing blade 422, and the end of the dispersing tooth 5 away from the dispersing blade 422 is set to be a tip. At this time, when the dispersing disk 41 drives the dispersing blade 422 to rotate, the dispersing tooth 5 on the dispersing blade 422 can better cut into the material, so as to achieve a better purpose of crushing the material.

[0047] In the initial state, the arch-breaking rod 04 is inclined, and the dispersing member 42 is arranged on one side of the dispersing disk 41 close to the universal joint 21. Then, when the material falls, it can drop onto the dispersing piece 422. Then, the dispersing piece 422 and the mounting shaft 421 rotate on the dispersing disk 41. At the same time, a detection component 7 for detecting the rotation speed of the dispersing shaft 31 is arranged on the dispersing disk 41. When the detection component 7 detects that the mounting shaft 421 rotates, it indicates that there is material that can push the dispersing piece 422 to rotate around the axis of the mounting shaft 421, and the material in the discharge pipe 03 is not completely caked. When the detection component 7 detects that the mounting shaft 421 does not rotate, it means that no material is falling. At this time, by controlling the rotation of the motor, the driving motor 11 drives the arch-breaking rod 04 to rotate at the same time, achieving the purpose of breaking the caked material in the bin 02.

[0048] Refer to Figures 5 to 8 , the control component 6 includes a control toothed belt 61 wound around multiple dispersing disks 41 at the same time, multiple control grooves 62 opened on the dispersing disks 41, and a control motor (not shown in the figure) fixed in the arch-breaking rod 04. The output shaft of the control motor is connected to one of the dispersing disks 41. A plurality of control grooves 62 are arranged on each dispersing disk 41, and the multiple control grooves 62 are evenly spaced along the circumferential direction of the dispersing disk 41, and the control toothed belt 61 cooperates with the control grooves 62 on the dispersing disk 41. Then, by controlling the rotation of the control motor, the dispersing disk 41 can be driven to rotate. Then, under the action of the control toothed belt 61 and the control grooves 62, multiple dispersing disks 41 are driven to rotate at the same time, and then it is convenient to drive the dispersing piece 422 to rotate through the dispersing disk 41.

[0049] Refer to Figures 5 to 8 , the detection component 7 includes a rotation speed sensor 71 fixed on the mounting shaft 421 and a controller arranged on the arch-breaking rod 04. The controller is used to connect to the first dispersing motor 33, the control motor, and the driving motor 11. When the rotation speed sensor 71 detects that the mounting shaft 421 does not rotate, the rotation speed sensor 71 sends a signal to the controller. At this time, the controller makes the first dispersing motor 33, the control motor, and the driving motor 11 work, thereby realizing the dispersing of the material in the bin 02. In this embodiment, the parameters of the rotation speed sensor 71 can be set as needed. For example, when the mounting shaft 421 rotates 10 circles per minute, the controller makes the first dispersing motor 33, the control motor, and the driving motor 11 work.

[0050] The implementation principle of a metal powder storage device according to an embodiment of the present application is as follows: When discharging is required, the valve on the discharge pipe 03 is opened, and at the same time, the first dispersion motor 33, the control motor, and the drive motor 11 are powered on. When caking occurs in the discharge pipe 03 and discharging is impossible, the rotation speed sensor 71 detects that the mounting shaft 421 is not rotating. The rotation speed sensor 71 sends a signal to the controller. At this time, the controller causes the first dispersion motor 33, the control motor, and the drive motor 11 to operate. The drive motor 11 drives the arch-breaking rod 04 to rotate, and at the same time, the first dispersion assembly 3 and the second dispersion assembly 4 on the arch-breaking rod 04 operate.

[0051] When the arch-breaking rod 04 rotates along the inner wall of the silo 02 and caked materials appear in front, due to the function of the universal joint 21, the moving speed of the upper end of the arch-breaking rod 04 slows down, and the lower end continues to rotate under the action of the drive motor 11. Since the moving speed of the lower end of the arch-breaking rod 04 is greater than that of the upper end, at this time, the upper end of the arch-breaking rod 04 will be pulled downward, making the arch-breaking rod 04 in an inclined state, and the distance between the upper end and the lower end of the arch-breaking rod 04 will become smaller, and the height of the arch-breaking rod 04 will become lower. At the same time, the arch-breaking rod 04 no longer abuts against the inner wall of the discharge pipe 03, so as to achieve the purpose of changing the moving direction of the arch-breaking rod 04. Since the moving speed of the upper end of the arch-breaking rod 04 is slow and the moving speed of the lower end is fast, at this time, the arch-breaking rod 04 no longer abuts against the inner wall of the discharge pipe 03, and the materials in the discharge pipe 03 will be cut, and then can be better and faster dispersed under the action of the first dispersion assembly 3 and the second dispersion assembly 4.

[0052] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
