Description

Technical Field

[0001] This invention relates to the field of silo arch breaking technology, specifically to a silo clearing device for silo arch breaking and cleaning, and also to a silo conveying device. Background Technology

[0002] Hybrid arching refers to the phenomenon where material at the silo outlet forms a stable arched structure due to friction and adhesion between particles and with the silo wall, leading to obstructed or even complete blockage of discharge. This problem is widespread in industries such as feed, cement, coal, mineral powder, and pharmaceuticals, seriously affecting production continuity and safety.

[0003] Chinese utility model patent application number 201822037118.8 - Hydraulic water spray combined arch breaking device, includes an arch breaking sleeve and an arch breaking cylinder. A guide post is provided on the outer wall of the arch breaking cylinder and is fitted inside the arch breaking sleeve through the guide post. The axis of the arch breaking sleeve and the axis of the arch breaking cylinder are parallel and have an offset of not less than three millimeters. A nozzle 17 is provided on the sealed end cap 14 of the arch breaking sleeve. The nozzle 17 is connected to a hollow tube. The hollow tube is connected and fixed to the end cap 14 and the inner wall of the arch breaking sleeve and extends out of the arch breaking sleeve. The part extending out of the arch breaking sleeve is a flexible hose. A fluid pressurization device is connected to the flexible hose. The axis of the nozzle 17 and the axis of the arch breaking sleeve form an angle of not less than fifteen degrees. A guide positioning device is provided at the open end of the arch breaking sleeve. The guide positioning device is provided with rollers that contact the side of the guide post.

[0004] This device can break up arches to some extent, but it has the following drawbacks: 1. Occupying the outlet of the silo obstructs the flow of materials during normal discharge, which can easily cause materials to accumulate near the outlet and affect the conveying efficiency. In particular, after the arch is broken, a large amount of material suddenly rushes into the outlet in a short period of time, which can easily cause secondary blockage.

[0005] 2. Even if secondary blockage does not occur after the arch breaks, there is still a risk of silo collapse. That is, the material originally supported by the arch loses its balance and will pour down like an avalanche, impacting and damaging downstream conveying equipment and threatening the stable operation of the entire production system. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a silo-breaking device and a silo conveying device for silo arch breaking and cleaning. The technical problems solved are: existing arch-breaking devices occupy the silo outlet, affecting conveying efficiency and easily causing blockages; and the impact of material after arch breaking on the downstream conveying design leads to damage. To solve the above technical problems, the technical solution adopted by this invention is: A silo-breaking and cleaning device for breaking up silos, characterized in that it comprises: A hanger that is slidably connected to the hopper, and the hanger has a material inlet; A sealing plate is used to block the discharge port of the silo. The sealing plate is connected to the hanger and is located on the side of the inlet. A power mechanism used to drive the feed inlet and the sealing plate to alternately be located below the hopper discharge outlet, so as to connect the feed inlet and the hopper discharge outlet, or to block the hopper discharge outlet with the sealing plate. The telescopic boom is connected to the sealing plate and can extend into the hopper when it is extended.

[0007] Furthermore, the hanger is equipped with a hanging rail, and the hanger is connected to the hopper through the hanging rail.

[0008] Furthermore, the hanging rail includes a locking rail fixedly connected to the hanger, the locking rail having a sliding plate, and the two sliding plates being fixedly installed on both sides of the material outlet of the hopper.

[0009] Furthermore, the rail includes a vertical plate and a horizontal plate fixedly connected in an L-shape. The horizontal plate is connected to bolts by threads, and the bolts can pass through the horizontal plate and abut against the upper surface of the slide plate.

[0010] Furthermore, the sealing plate has openings for the telescopic boom to pass through; The lower part of the sealing plate is provided with a mounting base, which is hinged to the telescopic arm. The mounting base is provided with an adjusting component for driving the telescopic arm to rotate around the hinge point with the mounting base.

[0011] Furthermore, a rotary drive is provided between the mounting base and the sealing plate, and the mounting base is rotatably connected to the sealing plate through the rotary drive.

[0012] Furthermore, the sealing plate includes a first fixing plate and a second fixing plate, and a cavity is provided between the first fixing plate and the second fixing plate. A follower plate is slidably arranged in the cavity, and the follower plate is sleeved on the outside of the telescopic arm to seal the opening.

[0013] Furthermore, the follower plate includes a steel core plate, which is wrapped with a rubber layer.

[0014] A silo conveying device is characterized by including a silo-breaking and cleaning device for silo arching, and a conveying mechanism fixedly installed at the lower part of the hanger.

[0015] Furthermore, the conveying mechanism is a feeder.

[0016] The beneficial effects of this invention are as follows: By setting an inlet and a sealing plate on the frame and enabling the alternation of the two through a power mechanism, when arch breaking is required, the sealing plate closes the outlet of the hopper, and the telescopic arm extends into the hopper to carry out arch breaking operations. This not only achieves arch breaking operations but also prevents the material after arch breaking from directly impacting downstream equipment, thereby improving equipment lifespan and safety.

[0017] The hinged and rotary drive design of the mounting base gives the telescopic boom the ability to break arches at multiple angles and in multiple directions, which can adapt to the needs of breaking arches of different positions and shapes in the silo and improve the efficiency of breaking arches.

[0018] The opening design on the sealing plate, combined with the follower plate, ensures that the follower plate can effectively seal the opening during the extension, retraction, and rotation of the telescopic boom. This ensures the airtightness of the hopper during the arch-breaking operation and prevents materials from falling through the opening to the area below the sealing plate when the telescopic boom moves. This not only ensures a clean environment for arch breaking but also reduces material waste.

[0019] Meanwhile, the follower plate adopts a structure of steel core plate wrapped with an outer rubber layer. The steel core plate provides sufficient structural strength to withstand the pressure of the material, while the rubber layer can fit tightly with the surface of the telescopic arm, further enhancing the sealing effect.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this invention. The specific implementation scheme of this invention is as follows: The silo-breaking device for clearing arches in a silo includes a hanger 2 slidably connected to the silo 1. The hanger 2 has an inlet 3. A sealing plate 4 for blocking the outlet of the silo 1 is provided on one side of the hanger 2, and the sealing plate 4 is fixedly connected to the hanger 2. The hanger 2 is connected to a power mechanism 13 for driving the inlet 3 and the sealing plate 4 to alternately be located below the outlet of the silo 1, so as to realize that the inlet 3 is connected to the outlet of the silo 1, or the sealing plate 4 blocks the outlet of the silo 1. The sealing plate 4 is connected to a telescopic arm 5, which is connected to the sealing plate 4. When the telescopic arm 5 is retracted, it does not affect the sliding contact between the upper end face of the sealing plate 4 and the lower end face of the outlet of the silo 1. When the telescopic arm 5 is extended, it can extend into the silo 1 to perform arch-breaking work. The power mechanism 13 enables the alternating switching between the feed inlet and the sealing plate. When it is necessary to break the arch, the sealing plate 4 closes the discharge port of the hopper 1, and the telescopic arm 5 extends into the hopper 1 to carry out the arch breaking operation. This not only enables the arch breaking operation, but also avoids the material after arch breaking from directly impacting downstream equipment, thereby improving the service life of the equipment, preventing the occurrence of hopper collapse accidents, and improving safety.

[0022] The hanger 2 is equipped with a hanging rail 6, which connects the hanger 2 to the hopper 1, allowing the hanger 2 to slide along the direction of movement of the power mechanism 13. Specifically, the hanging rail 6 includes a retaining rail 61 fixedly connected to the hanger 2, and a sliding plate 62 is mounted on the retaining rail 61. The two sliding plates 62 are fixedly installed on the hopper walls on both sides of the discharge port of the hopper 1. This structural design makes the sliding of the hanger 2 more stable and reliable. Through the cooperation of the retaining rail 61 and the sliding plate 62, the weight of the hanger 2 is transferred to the sliding plate 62, and then to the hopper wall of the hopper 1, ensuring the structural stability of the hanger 2 when carrying materials or performing arch-breaking operations.

[0023] Furthermore, the rail 61 includes a vertical plate 611 and a horizontal plate 612 fixedly connected in an L-shape. The vertical plate 611 is fixedly connected to the hanger 2, while the horizontal plate 612 extends horizontally inward, forming a slot structure on the inner side. The two sides of the slide plate 62 can be embedded in the slot structure and slide freely. In order to ensure sufficient lifting force on the lower structure, the rail 61 and the slide plate 62 are made of high-strength steel plates, such as Q345B low alloy high-strength structural steel, to ensure that the rail is not easily deformed or broken during long-term use.

[0024] The horizontal plate 612 is connected to the bolt 63 by a thread. The bolt 63 can pass through the horizontal plate 612 and abut against the upper end face of the slide plate 62. By tightening the bolt 63, the friction between the rail 61 and the slide plate 62 can be increased, thereby realizing the locking and fixing of the hanger 2 and the hopper 1.

[0025] It should be noted that the sealing plate 4 has an opening 7 for the telescopic arm 5 to pass through, and the sealing plate 4 has a mounting base 8 at its lower part. The mounting base 8 is hinged to the telescopic arm 5. The mounting base 8 is provided with an adjusting component 11 for driving the telescopic arm 5 to rotate around the hinge point with the mounting base 8. The adjusting component 11 can be a hydraulic cylinder. The two ends of the hydraulic cylinder 11 are respectively hinged to the mounting base 8 and the telescopic arm 5, so that the telescopic arm 5 can swing around the hinge point, realizing the angle adjustment of the telescopic arm 5 in the vertical plane, so as to meet the needs of breaking the arch at different height positions in the silo 1.

[0026] Furthermore, a rotary drive 10 is provided between the mounting base 8 and the sealing plate 4. The mounting base 8 is rotatably connected to the sealing plate 4 through the rotary drive 10, enabling the telescopic arm 5 to rotate 360 ​​degrees in the horizontal plane. In one embodiment, the rotary drive 10 can be a rotary cylinder in conjunction with a worm gear reducer to control the rotation angle of the mounting base 8, thereby driving the telescopic arm 5 to perform multi-directional scanning arch-breaking operations within the hopper 1.

[0027] It should be noted that the sealing plate 4 includes a first fixed plate 41 and a second fixed plate 42. A cavity is provided between the first fixed plate 41 and the second fixed plate 42. A follower plate 9 is slidably disposed in the cavity. The upper and lower end faces of the follower plate 9 are slidably connected to the side walls of the first fixed plate 41 and the second fixed plate 42, respectively. The follower plate 9 is sleeved on the outside of the telescopic arm 5 to seal the opening 7, ensuring the airtightness of the hopper during the arch breaking operation and preventing materials from falling through the opening to the bottom of the sealing plate 4 when the telescopic arm 5 moves. This ensures the cleanliness of the arch breaking environment and reduces material waste.

[0028] It should be noted that the follower plate 9 includes a steel core plate 91, and the steel core plate 91 is wrapped with a rubber layer 92. The steel core plate 91 provides sufficient structural strength to withstand the pressure of the material, while the rubber layer 92 can fit against the surface of the telescopic arm 5. Due to the properties of the rubber layer 92, the telescopic arm 5 is allowed to move relative to it during the adjustment process, which further enhances the sealing effect and prevents fine material particles from leaking out from the gap between the follower plate 9 and the telescopic arm 5.

[0029] The telescopic boom 5 is a sleeve-type telescopic boom structure, including a fixed boom 51, a primary boom 52 slidably disposed inside the fixed boom 51, a secondary boom 53 slidably disposed inside the primary boom 52, a drive cylinder disposed inside the secondary boom 53, one end of the drive cylinder is hingedly connected to the secondary boom 53, the other end of the drive cylinder is hingedly connected to the fixed boom 51, the fixed boom 51 is hingedly connected to the adjusting member 11, and the fixed boom 51 is sleeved inside the follower plate 9.

[0030] Specifically, both the adjusting component 11 and the power mechanism 13 can be hydraulic cylinders. One end of the hydraulic cylinder 13 is hinged to the hanger 2, and the other end of the hydraulic cylinder 13 is hinged to the side wall of the hopper 1.

[0031] The above embodiments can achieve arch breaking operations while avoiding direct impact of broken material on downstream equipment, thus improving equipment lifespan and safety. However, when the sealing plate 4 is located below the discharge port of the silo 1, it completes the sealing of the discharge port. During the arch breaking operation, the internal arching situation cannot be observed. Operators find it difficult to grasp the specific position, shape, and arch breaking effect of the arch frame inside the silo in real time. For example, if the arch frame is located on one side of the upper part of the silo and the telescopic arm is not accurately aligned with that position, the arch breaking operation will become superficial and will not effectively break the core arch frame structure.

[0032] To solve the above technical problems, this embodiment, based on the above embodiments, provides an installation groove 13 on the upper end face of the telescopic arm 5. Specifically, the installation groove 13 is located on the outer end face of the end cap 14 of the secondary arm 53. A camera 15 with night vision function is fixedly installed in the installation groove 13. The camera 15 transmits the situation inside the warehouse to an external monitoring terminal. Through the monitoring screen, the operator can intuitively see the specific position, size and structural characteristics of the arch frame, and then control the telescopic length, swing angle and rotation direction of the telescopic arm 5 to destroy the arch in a targeted manner, thereby improving the arch breaking efficiency.

[0033] It should be noted that a transparent protective plate 16 is fixedly installed on the end cap 14 on the outside of the mounting groove 13 to protect the camera 15 from direct impact of materials and dust contamination. The transparent protective plate 16 is made of tempered glass.

[0034] Furthermore, a nozzle 17 is connected to the end cap 14 on one side of the transparent protective plate 16. The nozzle 17 is connected to a telescopic tube, which extends or retracts synchronously with the telescopic arm 5. This ensures that during the arch-breaking operation of the telescopic arm 5, the nozzle 17 sprays high-pressure airflow or water flow towards the arched part. On the one hand, this can disperse the loose material covering the surface of the arch, allowing the camera 15 to observe the core structure of the arch more clearly. On the other hand, the high-pressure airflow or water flow can also apply a certain impact force to the arch, assisting the telescopic arm 5 in the arch-breaking operation. Especially in the coal mine silo application scenario, for arches formed by adhesion with high humidity, the water flow can reduce the adhesion between materials, making the arch-breaking process smoother.

[0035] It should be noted that a groove is provided on the outer surface of the end cap 14 on one side of the transparent protective plate 16. A cleaning brush 18 for cleaning the surface of the transparent protective plate 16 is provided in the groove. The cleaning brush 18 is connected to a power structure that drives it to rotate after it is disengaged from the groove. The power structure includes a hydraulic cylinder 19 installed in the telescopic arm 5. The hydraulic cylinder 19 is connected to the side wall of the telescopic arm 5. The output shaft of the hydraulic cylinder 19 is rotatably connected to a rotating shaft 20. The rotating shaft 20 is rotatably connected to the end cap 14. The upper end of the rotating shaft 20 is fixedly connected to the cleaning brush 18. A driven gear 21 is fixedly sleeved on the outside of the rotating shaft 20. A driving gear 22 is provided on one side of the driven gear 21 in a meshing manner. The driving gear 22 is fixedly connected to the output shaft of the servo motor 23 by a key. The driven gear 21 can move relative to the driving gear 22 along the axial direction. The servo motor 23 is fixedly connected to the side wall of the telescopic arm 5.

[0036] It should be noted that, initially, the cleaning brush 18 is hidden in the groove. When it is necessary to clean the surface of the transparent protective plate 16, the hydraulic cylinder 19 is activated. The output shaft of the hydraulic cylinder 19 drives the rotating shaft 20 to move. The rotating shaft 20 drives the driven gear 21 and the cleaning brush 18 to move upward. After the cleaning brush 18 disengages from the groove, the servo motor 23 is activated. The servo motor 23 drives the driving gear 22. The driving gear 22 drives the driven gear 21 through meshing. The driven gear 21 drives the rotating shaft 20 to rotate around its own central axis. The rotating shaft 20 drives the cleaning brush 18 to reciprocate and clean the surface of the transparent protective plate 16, promptly removing material dust or water mist adhering to the surface of the transparent protective plate 16, ensuring that the camera 15 always has a clear field of view.

[0037] In its non-operating state, the cleaning brush 18 is concealed within the recessed groove, reducing the impact and damage to the cleaning brush 18 caused by material breaking and after breaking the arch. Furthermore, the cleaning brush 18 includes a frame 24, with a groove on the lower end face of the frame 24. A wiper blade 25 is fixedly mounted within the groove, with its lower edge protruding from the lower end face of the frame 24, ensuring that the lower part of the wiper blade 25 fits snugly against the transparent protective plate 16. When the cleaning brush 18 detaches from the recessed groove, even if blocky material hits the frame 24, the frame 24 can directly transfer the force to the end cap 14, protecting the wiper blade 25. The frame 24 is made of high-strength aluminum alloy, ensuring structural strength while reducing overall weight.

[0038] To prevent material from entering the groove and affecting the reset of the cleaning brush 18, the lower part of the groove is connected to the inside of the telescopic arm 5, and a very small amount of material is discharged directly from the lower part of the telescopic arm.

[0039] Specifically, hydraulic cylinder 19 is a mini hydraulic cylinder.

[0040] The silo conveying device is characterized by including the aforementioned silo-breaking and cleaning device for silo arching. A conveying mechanism 12 is fixedly installed at the lower part of the hanger 2. In this embodiment, the conveying mechanism 12 is a feeder; in other embodiments, it can also be a fan-shaped gate or a chute. When the inlet 3 is connected to the outlet of the silo 1, the material can fall directly into the conveying mechanism 12 through the inlet 3. The conveying mechanism 12 then smoothly conveys the material to downstream equipment, realizing the integrated operation of arch breaking and conveying, reducing intermediate transfer links, and improving the overall material handling efficiency. Simultaneously, the conveying mechanism 12 is fixedly connected to the hanger 2 and slides together with the hanger 2. After arch breaking is completed, the hydraulic cylinder 13 is activated to drive the hanger 2 to move the conveying mechanism 12 below the outlet of the silo 1, allowing the material to enter the conveying mechanism 12 through the inlet 3. This avoids the trouble of material accumulating below the silo outlet after traditional arch breaking, requiring additional cleaning and transfer.

[0041] The conveying mechanism 12 enables this silo conveying device to not only have a high-efficiency arch-breaking function, but also to achieve continuous and stable material conveying. It is particularly suitable for industrial production scenarios with high requirements for material handling efficiency, such as silo systems in the mining field.

[0042] The working principle and process of this invention are as follows: Under normal working conditions, the hanger 2 is in the feeding position. At this time, the feeding port 3 is located below the discharge port of the silo 1. The sealing plate 4 and its connected telescopic arm 5 and other structures are in the non-working area. The material in the silo 1 falls into the feeder 12 below through the feeding port 3 under the action of gravity. The feeder 12 then transports the material to the downstream equipment to realize the normal material conveying process.

[0043] When the material cannot fall smoothly due to the arching state inside the silo 1, the operator starts the hydraulic cylinder 13 through the external control system. The hydraulic cylinder 13 drives the hanger 2 to move the feeder 12 along the hanging rail 6, so that the sealing plate 4 moves to the bottom of the discharge port of the silo 1, thus completing the sealing of the discharge port of the silo 1.

[0044] The camera 15 transmits the internal image of the silo 1 to the external monitoring terminal. The operator starts the rotary drive 10 and the hydraulic cylinder 11 according to the monitoring image. The rotary drive 10 drives the mounting base 8 and the telescopic arm 5 to rotate in the horizontal plane. The adjusting component 11 drives the telescopic arm 5 to swing to a predetermined angle in the vertical plane. During the above adjustment of the telescopic arm 5, the follower plate 9 fits tightly against the outer periphery of the telescopic arm 5 to ensure the sealing of the opening 7.

[0045] Start the drive cylinder to drive the first-stage arm 52 and the second-stage arm 53 to extend in sequence. Use the end of the telescopic arm 5 to touch the arched part to break the arch. If the surface of the arch is covered with loose material, the high-pressure water flow delivered by the telescopic pipe can be used through the nozzle 17 to impact the loose material and expose the core structure of the arch.

[0046] After the telescopic arm 5 has repeatedly contacted the arched part, when dust or water mist accumulates on the surface of the transparent protective plate 16 and affects the field of view of the camera 15, the telescopic arm 5 is moved away from the material, the hydraulic cylinder 19 is activated, the output shaft of the hydraulic cylinder 19 drives the rotating shaft 20 to move outward, the rotating shaft 20 drives the driven gear 21 and the cleaning brush 18 to move upward, after the cleaning brush 18 is disengaged from the groove, the servo motor 23 is activated, the servo motor 23 drives the driving gear 22, the driving gear 22 drives the driven gear 21 through meshing, the driven gear 21 drives the rotating shaft 20 to rotate around its own central axis, and then the rotating shaft 20 drives the cleaning brush 18 to rotate, reciprocating and oscillating to clean the surface of the transparent protective plate 16. After cleaning, the cleaning brush 18 returns to the groove.

[0047] The telescopic boom 5 continues to work, breaking the arch by directly contacting, pushing, and prying the arch frame. After the arch breaking operation is completed, the material falls into the hopper 1 above the first fixed plate 41. The telescopic boom 5 retracts, and the rotary drive 10 and the adjusting component 11 reset the telescopic boom 5 to its initial position.

[0048] The hydraulic cylinder 13 extends and drives the lifting frame 2 to slide, causing the inlet 3 to gradually return to below the outlet of the hopper 1. Because the upper surface of the first fixed plate 41 is in contact with the outlet of the hopper 1, it is equivalent to the outlet of the hopper 1 being gradually opened. Under the action of gravity, the material inside slowly falls through the inlet 3 into the feeder 12, preventing a large amount of material from instantly impacting the feeder 12, thus providing a buffer and protecting downstream equipment. Subsequently, the feeder 12 starts, smoothly conveying the arch-breaking material to the downstream conveyor belt or other processing equipment, completing the entire cycle of arch breaking and conveying.
