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 vital 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 silo. Due to its fine particle size and high surface energy, metal powder easily interacts 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, and then causing agglomeration and agglomeration, which seriously damages the fluidity and uniformity of the powder, not only affecting the normal use of the metal powder, but also leading to problems such as discharge blockage and unsmooth discharge.

[0003] For example, Chinese patent document CN108557290B discloses a silo arch breaking device and a feeder using the device, comprising a silo, a drive device, a rotating spindle, and an arch breaking screw. The rotating spindle is vertically arranged in the silo. The drive device is connected to the rotating spindle and drives the rotating spindle to rotate about its own axis. The arch breaking screw is transversely fixed to the rotating spindle, and a spiral rising member is provided at the end of the arch breaking screw away from the rotating spindle. The upper surface of the spiral rising member gradually rises from its front end to the rear end. The bottom of the silo is provided with a bottom plate, and the lower end of the silo wall is provided with an inward flange. The bottom plate is fixedly supported on the silo, and a discharge gap is defined 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 is fixed to the rotating spindle near the bottom plate and rotates with the rotating spindle. The rotating spindle is driven to rotate by a motor. The rotation of the rotating spindle drives the bottom arch breaking rod to rotate against the silo wall, and the material at the bottom is then broken by the arch breaking rod.

[0004] In the above-mentioned related technologies, a motor is installed at the bottom of the hopper to rotate and discharge the coal powder. 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 discharge is required, 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, the motor will burn out. Summary of the Invention

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

[0006] The metal powder storage device provided in this application adopts the following technical solution:

[0007] A metal powder storage device includes a hopper, an arch-breaking rod and a driving assembly arranged in the hopper, the arch-breaking rod is fitted with the inner wall of a tapered discharge pipe, the driving assembly includes a driving motor fixed on the hopper and a driving ring fixed on the driving motor, the driving ring is connected to the arch-breaking rod, the driving ring is provided with a mounting rod, the arch-breaking rod is provided with a first connecting assembly for connecting with the mounting rod, the first connecting assembly is configured as a universal joint, the driving ring and the arch-breaking rod are softly connected through the universal joint, the arch-breaking rod is provided with a first breaking up assembly and multiple second breaking up assemblies for breaking up agglomerated materials; when the arch-breaking rod encounters agglomerates in the rotation direction and is blocked, under the action of the universal joint, the moving speed of the upper end of the arch-breaking rod slows down, so that the arch-breaking rod is tilted during movement, and the upper and lower ends of the arch-breaking rod are not in the same plane.

[0008] By adopting the above technical solution, when the hopper has not been unloaded for a long time, the material in the hopper will clump. When the clumped material gets stuck in the arch breaker rod and the arch breaker rod cannot rotate, the drive motor needs a lot of force to drive the arch breaker rod to rotate, which will cause the drive motor to burn out, thereby reducing the service life of the drive motor; when the drive motor drives the drive ring to rotate, when the arch breaker rod is stuck and cannot rotate, under the action of the universal joint, the lower end of the arch breaker rod moves faster and the upper end moves slower, and then a gap will appear between the arch breaker rod and the inner wall of the discharge pipe. The agglomerated material is in this gap, which plays a role of avoidance. At this time, the angle of the arch breaking rod will be changed during the rotation, so that the arch breaking rod will no longer fit the inner wall of the discharge pipe. At the same time, the arch breaking rod and the agglomerated material will no longer be in direct contact, thereby reducing the resistance of the arch breaking rod when it rotates. Since the universal joint can rotate in different directions, when there are obstructions in different directions, the arch breaking rod can be moved to a position that does not contact the agglomerated material, and then the material can still be broken when passing through the position that does not contact the agglomerated material, thereby reducing the torque of the motor when it rotates and improving the service life of the motor.

[0009] 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 to the first rotating shaft, and a second mounting bracket rotatably connected to the second rotating shaft, wherein the first rotating shaft and the second rotating shaft are vertically arranged.

[0010] By adopting the above technical solution, since the first mounting frame rotates on the mounting rod, the arch-breaking rod can rotate around the rotation axis of the first mounting frame. Under the action of the first mounting shaft, the second mounting shaft and the second mounting frame, the arch-breaking rod can rotate in different directions, thereby reducing the resistance of the arch-breaking rod when it moves.

[0011] Optionally, a torsion spring is provided on the first mounting frame, the second mounting frame, 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 frame, 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 frame, one end of the torsion spring on the second mounting frame is fixed to the arch breaking rod, and the other end is fixed to the second mounting frame.

[0012] By adopting the above technical solution, when the arch breaking rod rotates, each torsion spring will be in a state of storing force, and then tend to drive the arch breaking rod to move in the opposite 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 effect of breaking up the agglomerated material, and make the material discharge effect better.

[0013] Optionally, the arch-breaking rod is provided with a first breaking up component for breaking up the agglomerated material, the first breaking up component includes a breaking up shaft rotatably connected to the arch-breaking rod, a plurality of first breaking up rods fixed on the breaking up shaft, and a first breaking up motor fixed on the arch-breaking rod, and the output shaft of the first breaking up motor is fixedly connected to the breaking up shaft.

[0014] By adopting the above technical solution, while the driving component drives the arch breaking rod to rotate, the first breaking motor rotates, driving the breaking shaft and multiple first breaking rods fixed on the breaking shaft to rotate, and then the agglomerated materials are broken up by the first breaking rod. After breaking up, the arch breaking rod can be rotated more easily, thereby achieving the purpose of reducing the resistance of the arch breaking rod and thus improving the service life of the driving component.

[0015] Optionally, the arch-breaking rod is provided with a plurality of second breaking-up components for breaking up the agglomerated materials; the second breaking-up components include a breaking-up disk arranged on the arch-breaking rod and a breaking-up piece arranged on the breaking-up disk, the breaking-up piece protrudes from the surface of the arch-breaking rod, and the arch-breaking rod is provided with a control component for driving the plurality of breaking-up disks to rotate simultaneously.

[0016] By adopting the above technical solution, the scattering pieces on the scattering disc extend out of the surface of the arch breaking rod, and then the control component drives the scattering disc and the scattering pieces to rotate. The scattering pieces will scatter the materials during the rotation process, thereby reducing the resistance of the arch breaking rod during rotation.

[0017] Optionally, a plurality of breaking discs are provided, and the plurality of breaking discs are evenly spaced along the length direction of the arch breaking rod.

[0018] Optionally, the control component includes a control toothed belt wound around multiple scattering disks at the same time, multiple control grooves opened on the scattering disks, and a control motor fixed in the arch breaking rod, the output shaft of the control motor is connected to one of the scattering disks, and the control toothed belt cooperates with the control groove on the scattering disk.

[0019] Optionally, the scattering part includes a plurality of scattering pieces fixed on a rotating shaft which is rotatably connected to the scattering disk, and the scattering pieces protrude from the surface of the scattering disk. The scattering disk is provided with a detection component for detecting the position of the scattering disk.

[0020] Optionally, the detection component includes a rotation speed sensor fixed on the breaking disc and a controller arranged on the arch breaking rod, and the controller is used to connect with the first breaking motor, the control motor and the drive motor.

[0021] Optionally, a plurality of scattering teeth are fixedly mounted on both ends of the scattering piece.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the driving motor drives the driving ring to rotate, and 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. The agglomerated material is in this gap, which plays 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 fits the inner wall of the discharge pipe, thereby reducing the resistance of the arch breaking rod during rotation, thereby reducing the torque of the motor during rotation and improving the service life of the motor.

[0024] 2. When the arch-breaking rod rotates, each torsion spring will be in a state of storing force, and then tend to drive the arch-breaking rod to move in the opposite 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 effect of breaking up the agglomerated material, and make the material discharge effect better.

DETAILED DESCRIPTION

[0036] The following combination Figures 1-10 This application is described in further detail.

[0037] The present application discloses a metal powder storage device. Figures 1 to 5 A metal powder storage device includes a frame 01 and a silo 02 arranged on the frame 01, a discharge pipe 03 is arranged at the bottom of the silo 02, and the discharge pipe 03 is arranged to have a conical structure. At the same time, a driving component 1 is provided on the discharge pipe 03, and a first connecting component 2 and an arch-breaking rod 04 arranged on the first connecting component 2 are provided on the driving component 1. The arch-breaking rod 04 abuts against the inner wall of the discharge pipe 03, and the driving component 1 is used to drive the arch-breaking rod 04 to rotate so that the arch-breaking rod 04 breaks up the agglomerated material inside, reduces the arch-breaking phenomenon of the material in the discharge pipe 03, and facilitates the material to fall from the discharge pipe 03. In addition, a first breaking component 3 and a second breaking component 4 and a detection component 7 for detecting the state of the material in the discharge pipe 03 are provided on the arch-breaking rod 04. The first breaking component 3 and the second breaking component 4 are used to break up the agglomerated material and reduce the resistance encountered by the arch-breaking rod 04 when it moves.

[0038] Reference Figures 1 to 5The driving component 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. A mounting groove is opened on the discharge pipe 03, the driving ring 12 is clamped in the mounting groove, and the driving ring 12 rotates in the mounting groove. The first connecting component 2 is arranged on the mounting rod 13. The driving motor 11 drives the driving ring 12 and the mounting rod 13 to rotate, and the mounting rod 13 drives the first connecting component 2 to rotate. The first connecting component 2 will drive the arch breaking rod 04 to rotate, thereby achieving the purpose of breaking the arch of the material.

[0039] Reference Figures 1 to 5 as well as Figure 9 and Figure 10 The first connecting component 2 is set as a universal joint 21. Under the action of the universal joint 21, when the arch-breaking rod 04 encounters a lump and is blocked in 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 obstruction of the agglomerated material, the movement speed of the upper end of the arch-breaking rod 04 slows down. At this time, the upper end of the arch-breaking rod 04 will move downward, and then the arch-breaking rod 04 will be in an inclined state, and the distance between the upper and lower ends of the arch-breaking rod 04 will become smaller. At this time, the height of the arch-breaking rod 04 will become lower, and at the same time, the arch-breaking rod 04 no longer abuts against the inner wall of the discharge pipe 03, thereby changing the moving direction of the arch-breaking rod 04.

[0040] Since the upper end of the arch breaking rod 04 moves slowly and the lower end moves quickly, 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 (such as Figure 9 and Figure 10 As shown), the material can then be broken up better and faster.

[0041] Reference Figures 2 to 5 The universal joint 21 includes a first mounting frame 211 arranged on the mounting rod 13, a first rotating shaft 212 rotatably connected to the first mounting frame 211, a second rotating shaft 213 fixed on the first rotating shaft 212 and a second mounting frame 214 rotatably connected to the second rotating shaft 213, the first rotating shaft 212 and the second rotating shaft 213 are arranged vertically; a rotating shaft 215 is fixedly installed on the first mounting frame 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 frame 211, the arch breaking rod 04 can be made to abut against the inner wall of the discharge pipe 03 without force.

[0042] Reference Figures 1 to 5A rotating shaft 215 is also fixedly installed on the second mounting frame 214, and the rotating shaft 215 on the second mounting frame 214 is rotatably connected to the arch breaking rod 04, and the rotating shaft 215 on the second mounting frame 214 is sleeved with a torsion spring 216, 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 frame 214, so that the arch breaking rod 04 can be reset after rotation; in addition, a torsion spring 216 is sleeved on the first rotating shaft 212 and the second rotating shaft 213. After the torsion spring 216 accumulates force to a certain extent, it will generate a tendency to drive the arch breaking rod 04 to reset in the reverse direction. Under the action of each torsion spring 216, the initial state of the arch breaking rod 04 will be pushed and abut against the inner wall of the discharge pipe 03.

[0043] Reference Figures 1 to 5 A limit block 06 is provided on the rotating shaft 215, and a limit slot 05 is provided on the mounting rod 13. The limit block 06 is slidably connected in the limit slot 05. In this embodiment, the limit slot 05 is not provided with 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.

[0044] Reference Figures 1 to 5 The first breaking up component 3 includes a breaking up shaft 31 rotatably connected to the arch breaking rod 04, a plurality of first breaking up rods 32 fixed on the breaking up shaft 31, and a first breaking up motor 33 fixed on the arch breaking rod 04. The output shaft of the first breaking up motor 33 is fixedly connected to the breaking up shaft 31. When the first breaking up motor 33 rotates, it can drive the breaking up shaft 31 to rotate, and then drive the plurality of breaking up rods 32 to rotate through the breaking up shaft 31.

[0045] During the rotation of the arch-breaking rod 04, after the first breaking-up motor 33 drives the first breaking-up rod 32 to effectively break up the agglomerated material, the overall state of the material becomes looser and easier to flow. In this case, the resistance encountered by the arch-breaking rod 04 during the rotation process will be significantly reduced; on the one hand, due to the loose state of the material, the arch-breaking rod 04 no longer needs to spend too much effort to break up the agglomerated structure of the material, so that 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 in resistance to the arch-breaking rod 04 also means that the drive assembly 1 does not need to bear excessive load; when the load is reduced, the pressure and wear on the various components inside the drive motor 11 will also be reduced accordingly, thereby extending the service life of the drive motor 11.

[0046] Reference Figures 5 to 8A placement slot is provided on the arch-breaking rod 04, and the second breaking up assembly 4 is arranged in the placement slot. The second breaking up assembly 4 includes a breaking up disc 41 rotatably connected to the arch-breaking rod 04 and a breaking up piece 42 arranged on the breaking up disc 41. The surface of the breaking up disc 41 is flush with the surface of the arch-breaking rod 04, and the breaking up piece 42 protrudes from the surface of the arch-breaking rod 04. A control assembly 6 for driving the breaking up disc 41 to rotate is provided on the arch-breaking rod 04; when the breaking up disc 41 rotates, the breaking up piece 42 is driven to rotate, and then the agglomerated materials can be broken up by the breaking up disc 41 and the breaking up piece 42 during the movement of the arch-breaking rod 04. There are multiple breaking up discs 41 on the arch-breaking rod 04, and the multiple breaking up discs 41 are evenly spaced along the length direction of the arch-breaking rod 04, and the control assembly 6 is used to drive the multiple breaking up discs 41 and the breaking up piece 42 to rotate at the same time, so that the second breaking up assembly 4 has a better effect on breaking up the materials.

[0047] Reference Figures 5 to 8 The scattering member 42 includes a mounting shaft 421 rotatably connected to the scattering disc 41 and a plurality of scattering pieces 422 fixed on the mounting shaft 421. In this embodiment, one end of the mounting shaft 421 is rotatably connected to the scattering disc 41, and the other end is used to install the detection component 7. The scattering pieces 422 protrude from the surface of the scattering disc 41. The axis of the mounting shaft 421 and the axis of the scattering disc 41 are perpendicularly arranged, and the plurality of scattering pieces 422 are evenly spaced along the circumference of the mounting shaft 421. Then, when the control component 6 drives the scattering disc 41 to rotate, the scattering disc 41 can drive the mounting shaft 421 and the scattering pieces 422 arranged on the mounting shaft 421 to rotate around the axis of the scattering disc 41, thereby achieving the purpose of scattering the material. In addition, when material falls in the discharge pipe 03, the discharged material can push the scattering pieces 422 to rotate around the axis of the mounting shaft 421, and the scattering disc 41 does not rotate at this time.

[0048] In order to facilitate the scattering piece 422 to scatter the material, a scattering tooth 5 is fixedly installed at the end of the scattering piece 422, and the end of the scattering tooth 5 away from the scattering piece 422 is set to a pointed end. At this time, when the scattering disc 41 drives the scattering piece 422 to rotate, the scattering teeth 5 on the scattering piece 422 can better cut into the material, thereby achieving the purpose of better crushing the material.

[0049] In the initial state, the arch-breaking rod 04 is tilted, and the scattering piece 42 is arranged on the side of the scattering disc 41 close to the universal joint 21. Then, when the material falls, it can fall onto the scattering piece 422, and then the scattering piece 422 and the mounting shaft 421 rotate on the scattering disc 41. At the same time, a detection component 7 for detecting the rotation speed of the scattering shaft 31 is provided on the scattering disc 41. When the detection component 7 detects that the mounting shaft 421 is rotating, it indicates that there is material that can push the scattering piece 422 to rotate around the axis of the mounting shaft 421, and the material in the discharge pipe 03 is not completely agglomerated. When the detection component 7 detects that the mounting shaft 421 is not rotating, it indicates that no material has fallen. At this time, by controlling the rotation of the motor, the driving motor 11 drives the arch-breaking rod 04 to rotate, thereby achieving the purpose of crushing the agglomerated material in the silo 02.

[0050] Reference Figures 5 to 8 The control component 6 includes a control toothed belt 61 wound around multiple scattering discs 41 at the same time, a plurality of control slots 62 opened on the scattering discs 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 scattering discs 41. There are multiple control slots 62 on each scattering disc 41. The multiple control slots 62 are evenly spaced along the circumference of the scattering disc 41, and the control toothed belt 61 cooperates with the control slots 62 on the scattering disc 41; then, by rotating the control motor, the scattering disc 41 can be driven to rotate, and then, under the action of the control toothed belt 61 and the control slot 62, the multiple scattering discs 41 are driven to rotate at the same time, and then it is convenient to drive the scattering piece 422 to rotate through the scattering disc 41.

[0051] Reference Figures 5 to 8 The detection assembly 7 includes a speed sensor 71 fixed on the mounting shaft 421 and a controller provided on the arch breaking rod 04. The controller is used to connect to the first breaking motor 33, the control motor, and the drive motor 11. When the speed sensor 71 detects that the mounting shaft 421 is not rotating, the speed sensor 71 sends a signal to the controller. At this time, the controller enables the first breaking motor 33, the control motor, and the drive motor 11 to work, thereby achieving breaking up of the materials in the silo 02. In this embodiment, the parameters of the speed sensor 71 can be set as needed. For example, when the mounting shaft 421 rotates 10 times per minute, the controller enables the first breaking motor 33, the control motor, and the drive motor 11 to work.

[0052] The implementation principle of a metal powder storage device in an embodiment of the present application is: when unloading is required, the valve on the discharge pipe 03 is opened, and the first breaking up motor 33, the control motor and the drive motor 11 are energized at the same time. When lumps appear in the discharge pipe 03 and the material cannot be unloaded, the speed sensor 71 detects that the mounting shaft 421 is not rotating, and the speed sensor 71 sends a signal to the controller. At this time, the controller makes the first breaking up motor 33, the control motor and the drive motor 11 work, and the drive motor 11 drives the arch breaking rod 04 to rotate, and at the same time, the first breaking up component 3 and the second breaking up component 4 on the arch breaking rod 04 work.

[0053] When the arch-breaking rod 04 rotates against the inner wall of the silo 02 and agglomerated material appears in front, due to the action of the universal joint 21, the speed of movement of the upper end of the arch-breaking rod 04 slows down, and the lower end continues to rotate under the action of the driving motor 11. Since the moving speed of the lower end of the arch-breaking rod 04 is greater than the moving speed of the upper end, the upper end of the arch-breaking rod 04 will be pulled downward, so that the arch-breaking rod 04 is in an inclined state, and the distance between the upper and lower ends of the arch-breaking rod 04 will become smaller, the height of the arch-breaking rod 04 will become lower, and at the same time, the arch-breaking rod 04 no longer abuts against the inner wall of the discharge pipe 03, thereby changing the moving direction of the arch-breaking rod 04. Since the upper end of the arch-breaking rod 04 moves slowly and the lower end moves quickly, 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, and then under the action of the first and second disintegrating components 3 and 4, the material can be better and faster dispersed.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
