Description

Technical Field

[0001] The present invention relates to the technical field of silos, and particularly to a low-position powder silo. Background Art

[0002] In the process of sewage treatment, different chemicals need to be configured for each process to react with various substances in the sewage to form precipitates. Before preparation, these chemicals are mostly in powder form, and these powdered chemicals are usually stored in powder silos. During preparation, the stored powder is transported from the powder silo to a solvent preparation device for mixing.

[0003] A fully automatic powder silo level real-time display device disclosed in a Chinese patent document with the authorization announcement number CN113526175B includes a driving motor, a spreading device, a material gathering device, and a driving device. The driving motor is installed on the top of the silo barrel, a winding drum is installed at the output end of the driving motor, a winding rope is provided on the winding drum, one end of the winding rope passing through the top of the silo barrel is fixed with a connecting block. The spreading device is used to level the bulging materials when adding materials into the silo barrel, and the spreading device is installed inside the silo barrel. The material gathering device is used to gather the surrounding materials to the central depression when discharging materials from the silo barrel, and the material gathering device is installed inside the silo barrel. The driving device is used to drive the spreading device and the material gathering device to move, the driving device is installed inside the silo barrel, and a level gauge is installed on the driving device.

[0004] However, the structural design of the above related technology: Although the material gathering device can gather the materials outside the depression area formed during discharging to the depression area, when the powder enters the silo, it usually naturally accumulates at the bottom of the silo in a loose state. Due to the lack of external compaction, the gaps between powder particles are large and the density is low, and a tight stacking structure cannot be formed. This will not only affect the metering judgment of the powder in the silo, but also reduce the space utilization rate of the silo.

[0005] Therefore, a low-position powder silo is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The present invention provides a low-position powder silo, aiming to solve the problems in the related technology that it is inconvenient to compact loose powder, which will affect the metering judgment of the powder in the silo and reduce the space utilization rate of the silo.

[0007] The low-position powder silo of the present invention includes a silo, a feeding mechanism, and a compaction mechanism. The feeding mechanism includes a discharging component rotatably arranged in the silo and a plurality of arch-breaking components annularly distributed on the discharging component. The discharging component can slide up and down in the silo. The compaction mechanism includes a lifting component installed on the discharging component and a compaction component that can slide vertically on the discharging component;

[0008] The arch-breaking assembly includes a connecting plate installed at the bottom end of the discharging assembly and an arch-breaking plate installed at the bottom of the connecting plate and having elasticity. When the arch-breaking plate opens, it is used to convey materials.

[0009] The compaction assembly includes a compaction ring installed on the lifting assembly and an elastic connecting piece installed inside the compaction ring. When the compaction ring moves downward, the elastic connecting piece closes the arch-breaking plate, so that the bottom end of the discharging assembly is closed, so that the compaction ring can follow the discharging assembly to compact the materials.

[0010] When conveying materials, the discharging assembly conveys the external materials to the inside of the silo. During the process of conveying the materials to the silo, the lifting assembly drives the compaction ring to gradually move downward. When the compaction ring moves to the outer side position of the arch-breaking plate, the elastic connecting piece presses against the arch-breaking plate, prompting the multiple arch-breaking plates to approach each other and close tightly, thereby completely closing the bottom end of the lifting cylinder, preventing the materials from leaking or scattering during the compaction process. At this time, the arch-breaking plate is located inside the compaction ring. Then, the discharging assembly drives the lifting assembly and the compaction ring to move downward. During the downward movement of the discharging assembly, the compaction ring applies pressure to the materials in the silo, thereby compacting the materials in the silo, reducing the space occupied by the silo, and thus improving the space utilization rate in the silo.

[0011] Preferably, the feeding mechanism further includes a rotating assembly rotatably connected above the silo. The rotating assembly includes a rotating cylinder, a first gear, and two sliding grooves. The two sliding grooves are respectively opened on both sides of the inner wall of the rotating cylinder, and the first gear is installed on the outside of the rotating cylinder.

[0012] Preferably, the discharging assembly includes a lifting cylinder, a sliding ring, two sliders, and multiple tooth grooves. The bottom end of the lifting cylinder is located inside the silo, the top end of the lifting cylinder is located inside the rotating cylinder, the sliding ring is installed at the top end of the lifting cylinder, the two sliders are respectively installed on both sides of the sliding ring and are slidably connected in the sliding grooves, and the multiple tooth grooves are uniformly opened on the lifting cylinder in the vertical direction.

[0013] Preferably, the shape of the connecting plate is arc-shaped. The connecting plate is installed at the bottom end of the lifting cylinder. The multiple connecting plates can form a ring at the bottom end of the lifting cylinder. A convex block is installed on the outside of the connecting plate, and the outside of the convex block has an arc-shaped surface.

[0014] Preferably, the shape of the arch-breaking plate is fan-shaped. The arch-breaking plate has a large end and a small end, and the large end of the arch-breaking plate is installed on the top of the connecting plate.

[0015] When the arch-breaking plates are separated, the materials in the discharging assembly can be conveyed into the silo. When the arch-breaking plates are closed, the bottom end of the discharging assembly is closed, thereby blocking the materials from entering the silo.

[0016] Preferably, a driving mechanism is provided at the top of the silo. The driving mechanism includes a first motor, a second gear, a second motor, and a third gear. The second gear is installed on the first motor and meshes with the first gear. The third gear is installed on the second motor and meshes with the tooth grooves on the lifting cylinder.

[0017] Through the cooperation of the first motor, the second gear, and the first gear, the rotating cylinder can be driven to rotate. At the same time, the rotating cylinder can drive the lifting cylinder to rotate in the silo to drive the rotated arch-breaking plates after closing. Through the cooperation of the second motor, the third gear, and the tooth grooves, the lifting cylinder can be driven to slide up and down in the silo.

[0018] Preferably, the elastic connecting member includes a fixed cylinder, a sliding shaft, and a pressing member. The fixed cylinder is installed on the inner wall of the compaction ring. The sliding shaft is elastically slidably connected in the fixed cylinder along the axis of the fixed cylinder. One end of the sliding shaft penetrates through one end of the fixed cylinder and extends to the outside of the fixed cylinder. The pressing member is installed at one end of the sliding shaft.

[0019] During the downward movement of the compaction ring, the sliding shaft gradually moves towards the outside of the fixed cylinder. At the same time, the sliding shaft presses the arch-breaking plates through the pressing member to close the multiple arch-breaking plates.

[0020] Preferably, the compaction mechanism further includes a closing component. The closing component includes an extrusion component and an adjustment component. The adjustment component is installed on the compaction component and corresponds to the arch-breaking plates. The extrusion component is installed on the adjustment component.

[0021] Preferably, the extrusion component includes a mounting seat, a rotating shaft, a fourth gear, a fifth gear, a rotating shaft, and two adjusting plates. The mounting seat is installed on the compaction ring. The rotating shaft is rotatably connected to the inner wall of the mounting seat. The fourth gear is installed on the rotating shaft. The fifth gear meshes with the fourth gear. The rotating shaft is installed in the middle of the fifth gear and is rotatably connected to the mounting seat. The two adjusting plates are respectively installed at both ends of the rotating shaft.

[0022] Preferably, the adjustment component includes a connecting cylinder, a sliding rod, and a pressing ball. The connecting cylinder is installed on the mounting seat. The sliding rod is elastically slidably connected in the connecting cylinder in the horizontal direction. One end of the sliding rod penetrates through the connecting cylinder and extends to the outside of the connecting cylinder. The pressing ball is installed at one end of the sliding rod. The pressing ball can contact the convex block. The other end of the sliding rod penetrates through one side of the mounting seat and is hinged to the rotating shaft.

[0023] When the compaction ring drives the pressing ball on the connecting cylinder to move to the position of the convex block through the mounting seat, the convex block presses the pressing ball, causing the pressing ball to approach the connecting cylinder. At this time, the pressing ball drives the rotating shaft to rotate through the sliding rod. The rotating shaft drives the adjusting plate on the rotating shaft to rotate through the fifth gear on the fourth gear. During the rotation of the adjusting plate, the arch-breaking plates are extruded to close the multiple arch-breaking plates so that the arch-breaking plates can penetrate into the compacted material.

[0024] Adopting the above technical solution, the beneficial effects of the present invention are as follows: During the conveying process of the material, the lifting component drives the compaction ring to move downward. When the compaction ring moves to the outside of the arch-breaking plate, the elastic connecting piece presses against the arch-breaking plate, causing multiple arch-breaking plates to approach and close to each other to close the bottom end of the lifting cylinder. At this time, the arch-breaking plate is located inside the compaction ring. Then, the discharging component drives the compaction ring to move downward. During the downward movement of the discharging component, the compaction ring compacts the material in the silo, thereby improving the space utilization rate in the silo.

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] As Figures 1 to 8 shown, the powder low-level silo of the present invention includes a silo 10, a feeding mechanism 20, a driving mechanism 30, and a compacting mechanism 40. The feeding mechanism 20 is arranged inside the silo 10, the driving mechanism 30 is arranged on the top of the silo 10 for driving the feeding mechanism 20 to operate, and the compacting mechanism 40 is arranged outside the feeding mechanism 20 to compact the materials in the silo 10.

[0040] When adding materials to the silo 10, the discharge port of the external conveyor is rotatably connected to the feeding end of the feeding mechanism 20, and the materials enter the silo 10 through the discharging end of the feeding mechanism 20. During the process of material transportation, the driving mechanism 30 drives the discharging end of the feeding mechanism 20 to continuously move upward to continuously add materials to the silo 10. During the process of the feeding mechanism 20 adding materials to the silo 10, the compacting mechanism 40 reciprocally slides on the feeding mechanism 20 to compact the materials.

[0041] As Figures 1 to 2 shown, the silo 10 includes a housing 11, support columns 12, a mounting plate 13, and a receiving cylinder 14. The upper half of the housing 11 is cylindrical, and the lower half is conical. The number of support columns 12 is multiple, and the multiple support columns 12 are annularly arranged around the axis of the housing 11 at the top of the housing 11. The mounting plate 13 is mounted on the tops of the multiple support columns 12. The middle of the mounting plate 13 has a central hole, and the feeding mechanism 20 is rotatably connected in the central hole of the mounting plate 13. The number of receiving cylinders 14 is two, and the two receiving cylinders 14 are symmetrically distributed around the axis of the housing 11 at the top of the mounting plate 13. The bottom end of the receiving cylinder 14 penetrates the top end of the housing 11 and is connected to the inside of the housing 11.

[0042] Continue to refer toFigures 1 to 2 As shown, the feeding mechanism 20 includes a rotating assembly 21, a discharging assembly 22, and a plurality of arch-breaking assemblies 23. The rotating assembly 21 is rotatably connected to the mounting plate 13, the discharging assembly 22 is slidably connected in the rotating assembly 21, and the plurality of arch-breaking assemblies 23 are annularly arrayed with the axis of the discharging assembly 22 as the center and mounted at the bottom end of the discharging assembly 22.

[0043] As Figure 2 and Figure 4 shown, the rotating assembly 21 includes a rotating cylinder 211, a chute 212, and a first gear 213. The bottom end of the rotating cylinder 211 is rotatably connected to the central hole of the mounting plate 13. There are two chutes 212, and the two chutes 212 are respectively opened on both sides of the inner wall of the rotating cylinder 211. The first gear 213 is mounted on the outside of the rotating cylinder 211 and located at the top of the mounting plate 13.

[0044] As Figures 2 to 4 shown, the discharging assembly 22 includes a lifting cylinder 221, a tooth groove 222, a slip ring 223, and a slider 224. The bottom end of the lifting cylinder 221 is located inside the housing 11, and the top end of the lifting cylinder 221 penetrates through the top end of the housing 11 and extends into the inside of the rotating cylinder 211. The slip ring 223 is mounted on the outside of the top end of the lifting cylinder 221, and the outside of the slip ring 223 is slidably connected to the inside of the rotating cylinder 211. There are two sliders 224, and the two sliders 224 are respectively mounted on both sides of the slip ring 223 and slidably connected in the chutes 212. There are a plurality of tooth grooves 222, and the plurality of tooth grooves 222 are uniformly opened on the outside of the lifting cylinder 221 in the vertical direction.

[0045] The lifting cylinder 221 slides up and down in the rotating cylinder 211, and the position of the bottom end of the lifting cylinder 221 in the housing 11 can be adjusted to adjust the discharging position of the lifting cylinder 221, so as to continuously convey materials into the housing 11.

[0046] Continuing to refer to Figures 2 to 4 shown, the arch-breaking assembly 23 includes a connecting plate 231, an arch-breaking plate 232, and a convex block 233. The shape of the connecting plate 231 is arc-shaped, and the connecting plates 231 in the plurality of arch-breaking assemblies 23 can form a ring at the bottom end of the lifting cylinder 221. The top of the connecting plate 231 is mounted at the bottom end of the lifting cylinder 221. The shape of the arch-breaking plate 232 is fan-shaped, and the arch-breaking plate 232 is made of an elastic metal plate. The arch-breaking plate 232 has a large end and a small end, and the large end of the arch-breaking plate 232 is mounted at the top of the connecting plate 231. In the initial state, the small ends of the arch-breaking plates 232 in the plurality of arch-breaking assemblies 23 are set away from the axis of the lifting cylinder 221, so that materials can be discharged from the lifting cylinder 221. The convex block 233 is mounted on the outside of the connecting plate 231, and the outside of the convex block 233 has an arc-shaped surface.

[0047] When the arch-breaking plate 232 is subjected to an inward extrusion force, the small end of the arch-breaking plate 232 gradually approaches the axis of the lifting cylinder 221, causing multiple arch-breaking plates 232 to form a cone to close the bottom end of the lifting cylinder 221. At this time, the material in the lifting cylinder 221 cannot be discharged into the housing 11.

[0048] As Figures 1 to 4 shown in the figure, the driving mechanism 30 includes a first motor 31, a second gear 32, a second motor 33, and a third gear 34. The first motor 31 is installed on one side of the bottom end of the mounting plate 13. The second gear 32 is located at the top end of the mounting plate 13 and meshes with the first gear 213. The bottom end of the first gear 213 is connected to the driving shaft of the first motor 31. The second motor 33 is installed on one side of the top end of the housing 11 through a support block. One end of the third gear 34 is connected to the driving shaft of the second motor 33 and meshes with the tooth groove 222 on the lifting cylinder 221.

[0049] When the first motor 31 drives the second gear 32 to rotate, the second gear 32 drives the rotating cylinder 211 to rotate through the first gear 213. At the same time, the rotating cylinder 211 drives the lifting cylinder 221 to rotate inside the housing 11 through the slider 224. When the second motor 33 drives the third gear 34 to rotate, the third gear 34 drives the lifting cylinder 221 to slide up and down in the housing 11 through the tooth groove 222 to change the position of the discharge end of the lifting cylinder 221.

[0050] As Figures 2 to 5 shown in the figure, the compaction mechanism 40 includes a lifting assembly 41, a compaction assembly 42, and a closing assembly. The lifting assembly 41 is installed outside the lifting cylinder 221. The lifting assembly 41 can drive the compaction assembly 42 to move downward. The compaction assembly 42 is slidably connected to the outside of the bottom end of the lifting cylinder 221. There are multiple closing assemblies, and the number of multiple closing assemblies is the same as that of the arch-breaking plates 232. The multiple closing assemblies are distributed in a circular array around the axis of the compaction assembly 42 at the bottom end of the compaction assembly 42. The closing assembly includes an extrusion assembly 43 and an adjustment assembly 44. The adjustment assembly 44 is installed at the bottom end of the compaction assembly 42 and corresponds to the arch-breaking plate 232. The extrusion assembly 43 is installed on one side of the adjustment assembly 44.

[0051] During the downward movement of the compaction assembly 42, under the action of the convex block 233, the extrusion assembly 43 can drive the adjustment assembly 44 to extrude the arch-breaking plate 232, so that multiple arch-breaking plates 232 approach each other to close the bottom end of the lifting cylinder 221. When the extrusion assembly 43 leaves the area of the convex block 233, the adjustment assembly 44 resets. At this time, as the compaction assembly 42 continues to move downward, the compaction assembly 42 can extrude the arch-breaking plate 232 again. When the bottom end of the lifting cylinder 221 is closed again, the second motor 33 drives the lifting cylinder 221 to move downward through the third gear 34. At this time, the lifting cylinder 221 drives the compaction assembly 42 to move downward and compact the powder in the housing 11.

[0052] AsFigures 3 to 5 As shown, the lifting assembly 41 includes a mounting frame 411 and a telescopic member 412. The mounting frame 411 is installed on the outside of the lifting cylinder 221 and is disposed close to the compaction assembly 42. There are two telescopic members 412. The fixed ends of the two telescopic members 412 are respectively installed on both sides of the top of the mounting frame 411, and the movable ends of the two telescopic members 412 are respectively installed on both sides of the top end of the compaction assembly 42. In this embodiment, the telescopic member 412 is a cylinder. In other embodiments, the telescopic member 412 is an electric telescopic rod or a hydraulic cylinder. When the movable end of the telescopic member 412 extends outwards, it can drive the compaction assembly 42 to move downwards.

[0053] As Figures 2 to 7 shown, the compaction assembly 42 includes a compaction ring 421 and an elastic connecting member. A cavity 422 communicating with the outside is formed inside the compaction ring 421. The outer wall of the compaction ring 421 is slidably connected to the inner wall of the housing 11. The top end of the compaction ring 421 is connected to the movable end of the telescopic member 412. There are multiple elastic connecting members. The multiple elastic connecting members are located inside the cavity 422 and respectively correspond to multiple arch-breaking plates 232.

[0054] The elastic connecting member includes a fixed cylinder 423, a sliding shaft 424, a pressing member 425 and a first spring 426. The fixed cylinder 423 is installed on the inner wall of the compaction ring 421. One end of the sliding shaft 424 is located inside the fixed cylinder 423. The first spring 426 is installed between the inner wall of the fixed cylinder 423 and the sliding shaft 424 to drive the sliding shaft 424 to reset. The other end of the sliding shaft 424 penetrates through one end of the fixed cylinder 423 and extends to the outside of the fixed cylinder 423. The pressing member 425 is installed at the other end of the sliding shaft 424. In this embodiment, the pressing member 425 is spherical.

[0055] During the process of the telescopic member 412 driving the compaction ring 421 to move downwards, the pressing member 425 can press the arch-breaking plates 232, causing the multiple arch-breaking plates 232 to approach each other. When the pressing member 425 moves to the small end of the arch-breaking plate 232, the multiple arch-breaking plates 232 will close the bottom end of the lifting cylinder 221.

[0056] As Figure 5 and Figure 8As shown, the extrusion assembly 43 includes a mounting base 431, a rotating shaft 432, a fourth gear 433, a first hinge seat 434, a fifth gear 435, a rotating shaft 436, and an adjusting plate 437. The mounting base 431 is installed at the bottom end of the compaction ring 421. The rotating shaft 432 is rotatably connected to one side of the inner wall of the mounting base 431. The fourth gear 433 is installed on the outer side of one end of the rotating shaft 432. The first hinge seat 434 is installed in the middle of the outer side of the rotating shaft 432. The fifth gear 435 meshes with the fourth gear 433, and the diameter of the fourth gear 433 is larger than that of the fifth gear 435 to increase the rotation speed of the fifth gear 435. The rotating shaft 436 is installed in the middle of the fifth gear 435 and is rotatably connected to the mounting base 431. Both ends of the rotating shaft 436 penetrate through the mounting base 431 and extend to the outside of the mounting base 431. There are two adjusting plates 437, and the two adjusting plates 437 are respectively installed at both ends of the rotating shaft 436.

[0057] Continue to refer to Figure 5 and Figure 8 As shown, the adjusting assembly 44 includes a connecting cylinder 441, a sliding rod 442, a pressing ball 443, a sliding plate 444, a second hinge seat 445, a hinge arm 446, and a second spring 447. The connecting cylinder 441 is installed on one side of the mounting base 431. The sliding rod 442 is located inside the connecting cylinder 441. One end of the sliding rod 442 penetrates through the connecting cylinder 441 and extends to the outside of the connecting cylinder 441. The pressing ball 443 is installed at one end of the sliding rod 442. The sliding plate 444 is installed on the outer side of the sliding rod 442 and is slidably connected inside the connecting cylinder 441. The second spring 447 is installed between the inner wall of the connecting cylinder 441 and the sliding plate 444 to drive the sliding rod 442 to reset. The other end of the sliding rod 442 penetrates through one side of the mounting base 431 and extends to the inside of the mounting base 431. The second hinge seat 445 is installed at the other end of the sliding rod 442. Both ends of the hinge arm 446 are respectively hinged to the first hinge seat 434 and the second hinge seat 445.

[0058] During the downward movement of the compaction ring 421, the compaction ring 421 drives the connecting cylinder 441 to move downward through the mounting base 431, so that the pressing ball 443 gradually contacts the convex block 233. During the contact between the pressing ball 443 and the convex block 233, the convex block 233 pushes the pressing ball 443 to approach the connecting cylinder 441. At this time, the pressing ball 443 drives the second hinge seat 445 to move horizontally through the sliding rod 442. The second hinge seat 445 drives the rotating shaft 432 to rotate through the first hinge seat 434 on the hinge arm 446. The rotating shaft 432 drives the adjusting plate 437 on the rotating shaft 436 to rotate through the fifth gear 435 on the fourth gear 433, so that the adjusting plate 437 presses the arch-breaking plate 232 to close the bottom end of the lifting cylinder 221.

[0059] Working principle: When conveying materials into the housing 11, the materials enter the lifting cylinder 221 through the rotating cylinder 211 and are discharged from the bottom end of the lifting cylinder 221. During the conveying process of the materials, the telescopic member 412 drives the compaction ring 421 to move downward, and the pressing member 425 presses against the arch-breaking plate 232, causing multiple arch-breaking plates 232 to approach each other and closing the bottom end of the lifting cylinder 221. At this time, the small end of the arch-breaking plate 232 is located inside the compaction ring 421.

[0060] Then, the second motor 33 drives the third gear 34 to rotate. The third gear 34 drives the lifting cylinder 221 to move downward in the housing 11 through the tooth groove 222. At the same time, the lifting cylinder 221 drives the compaction ring 421 to compact the materials in the housing 11, thereby improving the space utilization rate in the housing 11. Then, the second motor 33 drives the lifting cylinder 221 to move upward through the third gear 34. At the same time, the telescopic member 412 drives the compaction ring 421 to reset, so that the arch-breaking plates 232 unfold. Then, continue to convey materials into the housing 11 and repeat the above operations. After the material conveying is completed, the telescopic member 412 enters the receiving cylinder 14, and the compaction ring 421 is located at the uppermost position inside the housing 11.

[0061] When it is necessary to discharge the materials in the housing 11, the telescopic member 412 drives the compaction ring 421 to move downward. The compaction ring 421 drives the connecting cylinder 441 to move downward through the mounting seat 431, so that the pressing ball 443 moves to the position of the convex block 233. At this time, under the action of the convex block 233, the pressing ball 443 drives the second hinge seat 445 to move horizontally through the slide rod 442. The second hinge seat 445 drives the rotating shaft 432 to rotate through the first hinge seat 434 on the hinge arm 446. The rotating shaft 432 drives the adjusting plate 437 on the rotating shaft 436 to rotate through the fifth gear 435 on the fourth gear 433. During the rotation of the adjusting plate 437, it squeezes the arch-breaking plates 232, causing multiple arch-breaking plates 232 to approach each other and closing the bottom end of the lifting cylinder 221.

[0062] After the bottom end of the lifting cylinder 221 is closed, the first motor 31 drives the second gear 32 to rotate. The second gear 32 drives the rotating cylinder 211 to rotate through the first gear 213. At the same time, the rotating cylinder 211 drives the arch-breaking plates 232 to rotate inside the housing 11 through the lifting cylinder 221. At the same time, the second motor 33 drives the third gear 34 to rotate. The third gear 34 drives the arch-breaking plates 232 to move downward in the housing 11 through the tooth groove 222, so that the arch-breaking plates 232 drill into the compacted materials. At the same time, through the adjusting plate 437 on the arch-breaking plates 232, the compacted or agglomerated materials can be broken up. During the downward movement of the lifting cylinder 221, it also drives the compaction ring 421 to move downward to push the materials to move downward faster, thereby preventing the materials from bridging inside the housing 11 and facilitating the discharge of the materials from the housing 11.

[0063] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
