Description

Technical Field

[0001] The invention relates to the technical field of silos, and in particular to a low-level silo for powdered materials. Background Art

[0002] In the process of sewage treatment, different reagents need to be configured in each process in order to react with various substances in the sewage to form precipitation. The reagents are mostly in powder form before preparation, and these powdered reagents are usually stored in powder silos. During preparation, the stored powder is transported to the solvent preparation device through the powder silo for mixing.

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

[0004] However, the structural design of the above-mentioned related technology: although the material outside the depressed area formed during the discharge can be gathered into the depressed area by the gathering device, the powder is usually naturally accumulated at the bottom of the silo in a loose state when entering the silo. Due to the lack of compaction by external force, the gaps between the powder particles are large and the density is low, and a tight stacking structure cannot be formed. This will not only affect the measurement and judgment of the powder in the silo, but also reduce the space utilization rate of the silo.

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

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

[0007] The powder low-level silo of the present invention comprises a silo, a feeding mechanism and a compacting mechanism, wherein the feeding mechanism comprises a discharging assembly rotatably arranged in the silo and a plurality of annularly distributed arch-breaking assemblies installed on the discharging assembly, the discharging assembly being able to slide up and down in the silo, and the compacting mechanism comprising a lifting assembly installed on the discharging assembly and a compacting assembly capable of vertically sliding on the discharging assembly; The arch-breaking assembly includes a connecting plate installed at the bottom end of the discharging assembly and an elastic arch-breaking plate installed at the bottom of the connecting plate. The arch-breaking plate is used to convey materials when it is opened. The compaction assembly includes a compaction ring installed on the lifting assembly and an elastic connector installed on the inner side of the compaction ring. When the compaction ring moves downward, the elastic connector closes the arch plate to close the bottom end of the discharge assembly so that the compaction ring follows the discharge assembly to compact the material.

[0008] When conveying materials, the external materials are conveyed to the inside of the silo through the discharging assembly. During the process of conveying materials to the silo, the compacting ring is driven by the lifting assembly to gradually move downward. When the compacting ring moves to the outer position of the arch breaking plate, the elastic connecting part presses the arch breaking plate, causing multiple arch breaking plates to approach each other and close tightly, thereby completely closing the bottom end of the lifting cylinder to prevent leakage or scattering of materials during the compaction process. At this time, the arch breaking plate is located inside the compacting ring, and then the discharging assembly drives the lifting assembly and the compacting ring to move downward. During the downward movement of the discharging assembly, the compacting ring exerts pressure on the material in the silo, thereby compacting the material in the silo to reduce the space occupied by the silo, thereby improving the space utilization rate in the silo.

[0009] Preferably, the feeding mechanism also includes a rotating assembly rotatably connected above the silo, the rotating assembly includes a rotating cylinder, a gear 1 and two slide grooves, the two slide grooves are respectively opened on both sides of the inner wall of the rotating cylinder, and the gear 1 is installed on the outside of the rotating cylinder.

[0012] Preferably, the arch-breaking plate is fan-shaped, has a large end and a small end, and the large end of the arch-breaking plate is mounted on the top of the connecting plate.

[0013] When the arch-breaking plates are separated, the materials in the discharging assembly can be transported to the silo, and when the arch-breaking plates are closed, the bottom end of the discharging assembly is closed, thereby preventing the materials from entering the silo.

[0014] Preferably, a driving mechanism is provided on the top of the silo, and the driving mechanism includes motor one, gear two, motor two and gear three, wherein gear two is mounted on motor one and meshes with gear one, and gear three is mounted on motor two and meshes with the tooth groove on the lifting cylinder.

[0015] Motor 1 can drive the rotating cylinder to rotate through the cooperation of gear 2 and gear 1. At the same time, the rotating cylinder can drive the lifting cylinder to rotate in the silo to drive the closed broken arch plate to rotate. Motor 2 can drive the lifting cylinder to slide up and down in the silo through the cooperation of gear 3 and the tooth groove.

[0016] 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 to the inside of the fixed cylinder along the axial direction of the fixed cylinder, one end of the sliding shaft passes through one end of the fixed cylinder and extends to the outside of the fixed cylinder, and the pressing member is installed at one end of the sliding shaft.

[0017] During the downward movement of the compaction ring, the sliding shaft gradually moves toward the outside of the fixed cylinder, and at the same time, the sliding shaft presses the broken arch plates through the pressing piece, so that the multiple broken arch plates are closed.

[0021] When the compaction ring drives the top pressure ball on the connecting tube to the position of the protrusion through the mounting seat, the protrusion squeezes the top pressure ball, causing the top pressure ball to approach the connecting tube. At this time, the top pressure ball drives the rotating shaft to rotate through the sliding rod, and the rotating shaft drives the adjusting plate on the rotating shaft to rotate through the gear five on the gear four. During the rotation of the adjusting plate, the arch breaking plate is squeezed, so that multiple arch breaking plates are closed, so that the arch breaking plates can drill into the compacted material.

[0022] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: during the material transportation process, the compaction ring is driven downward by the lifting assembly, and when the compaction ring moves to the outside of the arch breaking plate, the elastic connecting part presses the arch breaking plate, so that the multiple arch breaking plates are close to each other and closed to close the bottom end of the lifting cylinder. At this time, the arch breaking plate is located inside the compaction ring, and then the discharging assembly drives the compaction ring to move downward. During the downward movement of the discharging assembly, the compaction ring compacts the material in the silo, thereby improving the space utilization rate in the silo.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 8 As shown, the powder low-level silo of the present invention comprises 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 to drive the feeding mechanism 20 to operate, and the compacting mechanism 40 is arranged outside the feeding mechanism 20 to compact the material in the silo 10.

[0034] When adding materials to the silo 10, the discharge port of the external conveyor is rotatably connected to the feed end of the feeding mechanism 20, and the materials enter the silo 10 through the discharge end of the feeding mechanism 20. During the material conveying process, the driving mechanism 30 drives the discharge 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 reciprocates and slides on the feeding mechanism 20 to compact the materials.

[0035] like Figure 1 to Figure 2 As shown, the silo 10 includes a shell 11, support columns 12, a mounting plate 13 and a receiving tube 14. The upper half of the shell 11 is cylindrical, and the lower half is conical. There are multiple support columns 12, and multiple support columns 12 are installed in a circular array at the top of the shell 11 with the axis of the shell 11 as the center.

[0036] Continue to refer Figure 1 to Figure 2As 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 installed at the bottom end of the discharging assembly 22 in a circular array with the axis of the discharging assembly 22 as the center.

[0037] like Figure 2 and Figure 4 As shown, the rotating assembly 21 includes a rotating cylinder 211, a slide groove 212 and a gear 1 213. The bottom end of the rotating cylinder 211 is rotatably connected to the central hole of the mounting plate 13. There are two slide grooves 212, which are respectively opened on both sides of the inner wall of the rotating cylinder 211. The gear 1 213 is installed on the outer side of the rotating cylinder 211 and located at the top of the mounting plate 13.

[0038] like Figures 2 to 4 As 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 shell 11, and the top end of the lifting cylinder 221 passes through the top end of the shell 11 and extends to the inside of the rotating cylinder 211. The slip ring 223 is installed 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 installed on both sides of the slip ring 223 and slidably connected in the slide groove 212. There are multiple tooth grooves 222, and multiple tooth grooves 222 are evenly opened on the outside of the lifting cylinder 221 along the vertical direction.

[0039] 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 shell 11 can be adjusted to adjust the discharge position of the lifting cylinder 221 , thereby continuously conveying materials into the shell 11 .

[0040] Continue to refer Figures 2 to 4 As shown, the arch breaking assembly 23 includes a connecting plate 231, an arch breaking plate 232 and a protrusion 233. The connecting plate 231 is in an arc shape, and the connecting plates 231 in the multiple 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 installed at the bottom end of the lifting cylinder 221. The arch breaking plate 232 is in a fan shape, 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 installed at the top of the connecting plate 231. In the initial state, the small end of the arch breaking plate 232 in the multiple arch breaking assemblies 23 is arranged away from the axis of the lifting cylinder 221, so that the material can be discharged from the lifting cylinder 221. The protrusion 233 is installed on the outside of the connecting plate 231, and the outside of the protrusion 233 has an arc surface.

[0041] 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, so that the multiple arch breaking plates 232 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 shell 11.

[0042] like Figures 1 to 4 As shown, the driving mechanism 30 includes a motor 1 31, a gear 2 32, a motor 2 33 and a gear 34. The motor 1 31 is mounted on one side of the bottom end of the mounting plate 13, the gear 2 32 is located at the top end of the mounting plate 13 and meshes with the gear 1 213, and the bottom end of the gear 1 213 is connected to the driving shaft of the motor 1 31. The motor 2 33 is mounted on one side of the top end of the housing 11 through a support block, and one end of the gear 34 is connected to the driving shaft of the motor 2 33 and meshes with the tooth groove 222 on the lifting cylinder 221.

[0043] When the motor 1 31 drives the gear 2 32 to rotate, the gear 2 32 drives the rotating cylinder 211 to rotate through the gear 1 213, and 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 motor 2 33 drives the gear 3 34 to rotate, the gear 3 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.

[0044] like Figures 2 to 5 As shown, the compaction mechanism 40 includes a lifting assembly 41, a compaction assembly 42 and a folding assembly. The lifting assembly 41 is installed on the outside of the lifting cylinder 221, and 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 folding assemblies, and the number of multiple folding assemblies is the same as the number of the arch-breaking plates 232. The multiple folding assemblies are distributed in a circular array at the bottom end of the compaction assembly 42 with the axis of the compaction assembly 42 as the center. The folding 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.

[0045] During the downward movement of the compacting assembly 42, under the action of the protrusion 233, the squeezing assembly 43 can drive the adjusting assembly 44 to squeeze the broken arch plates 232, so that the multiple broken arch plates 232 are close to each other, thereby closing the bottom end of the lifting cylinder 221. When the squeezing assembly 43 is out of the protrusion 233 area, the adjusting assembly 44 is reset, and at this time, as the compacting assembly 42 continues to move downward, the broken arch plates 232 can be squeezed again by the compacting assembly 42. When the bottom end of the lifting cylinder 221 is closed again, the motor 2 33 drives the lifting cylinder 221 to move downward through the gear 3 34, and at this time, the lifting cylinder 221 drives the compacting assembly 42 to move downward and compact the powder in the housing 11.

[0046] like Figures 3 to 5 As shown, the lifting assembly 41 includes a mounting frame 411 and a telescopic member 412. The mounting frame 411 is mounted on the outside of the lifting cylinder 221 and is arranged close to the compacting assembly 42. There are two telescopic members 412. The fixed ends of the two telescopic members 412 are respectively mounted on both sides of the top of the mounting frame 411, and the movable ends of the two telescopic members 412 are respectively mounted on both sides of the top of the compacting 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 outward, it can drive the compacting assembly 42 to move downward.

[0047] like Figures 2 to 7 As shown, the compaction assembly 42 includes a compaction ring 421 and an elastic connector. A cavity 422 communicating with the outside is provided on the inner side of the compaction ring 421, the outer wall of the compaction ring 421 is slidably connected to the inner wall of the housing 11, and the top of the compaction ring 421 is connected to the movable end of the telescopic member 412. There are multiple elastic connectors, and the multiple elastic connectors are located inside the cavity 422 and correspond to the multiple broken arch plates 232 respectively.

[0048] The elastic connecting member includes a fixed cylinder 423, a sliding shaft 424, a pressing member 425 and a spring 1 426. The fixed cylinder 423 is mounted on the inner wall of the compaction ring 421, one end of the sliding shaft 424 is located inside the fixed cylinder 423, and the spring 1 426 is mounted 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 passes through one end of the fixed cylinder 423 and extends to the outside of the fixed cylinder 423, and the pressing member 425 is mounted on the other end of the sliding shaft 424. In this embodiment, the pressing member 425 is spherical.

[0049] When the telescopic member 412 drives the compacting ring 421 to move downward, the pressing member 425 can press the broken arch plate 232 to make the multiple broken arch plates 232 approach each other. When the pressing member 425 moves to the small end of the broken arch plate 232, the multiple broken arch plates 232 close the bottom end of the lifting cylinder 221.

[0050] like Figure 5 and Figure 8As shown, the extrusion assembly 43 includes a mounting seat 431, a rotating shaft 432, a gear 433, a hinge seat 1 434, a gear 5 435, a rotating shaft 436 and an adjustment plate 437. The mounting seat 431 is mounted 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 seat 431, the gear 433 is mounted on the outer side of one end of the rotating shaft 432, and the hinge seat 1 434 is mounted on the outer middle part of the rotating shaft 432. The gear 5 435 is meshed with the gear 433, and the diameter of the gear 433 is larger than the diameter of the gear 5 435 to increase the rotation speed of the gear 5 435. The rotating shaft 436 is mounted in the middle part of the gear 5 435 and is rotatably connected to the mounting seat 431. Both ends of the rotating shaft 436 penetrate the mounting seat 431 and extend to the outside of the mounting seat 431. There are two adjustment plates 437, and the two adjustment plates 437 are respectively mounted on both ends of the rotating shaft 436.

[0051] Continue to refer Figure 5 and Figure 8 As shown, the adjustment assembly 44 includes a connecting tube 441, a sliding rod 442, a pressing ball 443, a sliding plate 444, a hinge seat 445, a hinge arm 446 and a spring 447. The connecting tube 441 is installed on one side of the mounting seat 431, and the sliding rod 442 is located inside the connecting tube 441. One end of the sliding rod 442 passes through the connecting tube 441 and extends to the outside of the connecting tube 441, and the pressing ball 443 is installed on one end of the sliding rod 442. The sliding plate 444 is installed on the outside of the sliding rod 442 and is slidably connected to the inside of the connecting tube 441. The spring 447 is installed between the inner wall of the connecting tube 441 and the sliding plate 444 to drive the sliding rod 442 to reset. The other end of the sliding rod 442 passes through one side of the mounting seat 431 and extends to the inside of the mounting seat 431, and the hinge seat 445 is installed on the other end of the sliding rod 442. The two ends of the articulated arm 446 are respectively articulated on the first articulated seat 434 and the second articulated seat 445 .

[0052] During the downward movement of the compaction ring 421, the compaction ring 421 drives the connection tube 441 to move downward through the mounting seat 431, so that the top pressure ball 443 gradually contacts the protrusion 233. During the contact between the top pressure ball 443 and the protrusion 233, the protrusion 233 pushes the top pressure ball 443 to approach the connection tube 441. At this time, the top pressure ball 443 drives the hinge seat 2 445 to move horizontally through the slide bar 442. The hinge seat 2 445 drives the rotating shaft 432 to rotate through the hinge seat 1 434 on the hinge arm 446. The rotating shaft 432 drives the adjusting plate 437 on the rotating shaft 436 to rotate through the gear 5 435 on the gear 433, so that the adjusting plate 437 squeezes the broken arch plate 232, so that the bottom end of the lifting tube 221 is closed.

[0053] 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 the broken arch plate 232, so that the multiple broken arch plates 232 are close to each other and the bottom end of the lifting cylinder 221 is closed. At this time, the small end of the broken arch plate 232 is located inside the compaction ring 421.

[0054] Then the motor 2 33 drives the gear 3 34 to rotate, and the gear 3 34 drives the lifting cylinder 221 to move down in the housing 11 through the tooth groove 222, and at the same time, the lifting cylinder 221 drives the compaction ring 421 to compact the material in the housing 11, thereby improving the space utilization rate in the housing 11, and then the motor 2 33 drives the lifting cylinder 221 to move up through the gear 3 34, and at the same time, the telescopic member 412 drives the compaction ring 421 to reset, so that the broken arch plate 232 is unfolded, and then the material is continuously transported into the housing 11, and the above operation is repeated. After the material is transported, the telescopic member 412 enters the accommodating cylinder 14, and the compaction ring 421 is located at the top of the interior of the housing 11.

[0055] When the material in the shell 11 needs to be discharged, the telescopic member 412 drives the compacting ring 421 to move downward, and the compacting ring 421 drives the connecting tube 441 to move downward through the mounting seat 431, so that the top pressure ball 443 moves to the position of the protrusion 233. At this time, the top pressure ball 443 drives the hinge seat 2 445 to move horizontally through the sliding rod 442 under the action of the protrusion 233, and the hinge seat 2 445 drives the rotating shaft 432 to rotate through the hinge seat 1 434 on the hinge arm 446. The rotating shaft 432 drives the adjusting plate 437 on the rotating shaft 436 to rotate through the gear 5 435 on the gear 433. During the rotation of the adjusting plate 437, the broken arch plate 232 is squeezed, so that the multiple broken arch plates 232 are close to each other and the bottom end of the lifting cylinder 221 is closed.

[0056] When the bottom end of the lifting cylinder 221 is closed, the motor 1 31 drives the gear 2 32 to rotate, and the gear 2 32 drives the rotating cylinder 211 to rotate through the gear 1 213. At the same time, the rotating cylinder 211 drives the arch-breaking plate 232 to rotate inside the housing 11 through the lifting cylinder 221. At the same time, the motor 2 33 drives the gear 3 34 to rotate, and the gear 3 34 drives the arch-breaking plate 232 to move downward in the housing 11 through the tooth groove 222, so that the arch-breaking plate 232 drills into the compacted material, and at the same time, the adjustment plate 437 on the arch-breaking plate 232 can break up the compacted or agglomerated material. In the process of moving downward, the lifting cylinder 221 also drives the compaction ring 421 to move downward to promote the material to move downward faster, thereby avoiding the material bridging phenomenon inside the housing 11, and facilitating the discharge of the material from the housing 11.

[0057] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
