Description

Technical Field

[0001] The embodiments of the present invention relate to the field of material unblocking technology, specifically to a pneumatic self-excited vibration type powder material unblocking device. Background Technology

[0002] Both coal and grain storage outlets face a high risk of blockage.

[0003] Coal has a certain degree of moisture and stickiness. During storage, due to its own weight, the coal at the bottom of the coal bunker experiences greater pressure, causing the particles to squeeze together. This increases the friction and adhesion between the coal particles, making them prone to clumping and clogging the outlet. This blockage is especially likely when the coal contains gangue or other impurities.

[0004] Grain silo outlets are also prone to blockage. During the accumulation process, grain can easily form an arch bridge effect, that is, an arch-shaped structure forms above the outlet, hindering the normal flow of grain. Moreover, if moisture-proof measures are not in place during storage, grain can easily absorb moisture from the air, becoming moldy and clumping, which in turn can block the grain silo outlet.

[0005] Currently, mechanical unblocking methods are commonly used to address blockages at the outlets of coal and grain bunkers. This involves manually clearing the blockage with a long-handled spatula. Operators use this method to reach into the bunker from the outlet and manually break up the blocking material. However, this method is labor-intensive, inefficient, and poses safety risks (material can easily fall in large quantities and bury the operators). Summary of the Invention

[0006] To overcome the above-mentioned defects, embodiments of the present invention provide a pneumatic self-excited vibration type powder material unblocking device, which solves the technical problems of low efficiency and unsafety of manual material unblocking in related technologies.

[0007] According to one aspect, at least one embodiment of the present invention provides a pneumatically self-excited vibration type powder material unblocking device, comprising: The main body has a space for vibration; A vibration component is reciprocatingly slidably disposed within the vibration space. The vibration component can drive the main body to vibrate during reciprocating sliding to clear the blocked material.

[0008] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The vibration component divides the vibration space into an upper space and a lower space; The top and bottom of the vibration assembly have an upper air hole and a lower air hole respectively communicating with the upper space and the lower space. The upper air hole and the lower air hole are used to release air. The air released from the upper air hole or the lower air hole drives the vibration assembly to slide back and forth.

[0009] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The vibration component has an air source hole for communicating with an external air source, and the air source hole is connected to the upper air hole or the lower air hole through a reversing component; The vibration component has upward sliding dynamics and downward sliding dynamics; When the reversing component connects the air source hole and the upper air hole, air is discharged from the upper air hole, and at this time the vibration component is in a downward dynamic. When the reversing component connects the air source port and the lower air port, air is discharged from the lower air port, and at this time the vibration component is in an upward sliding dynamic.

[0010] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The vibration assembly has a piston chamber, and the wall of the piston chamber has a first hole and a second hole, respectively. The first hole and the second hole are respectively used to communicate with the upper air hole and the lower air hole, and both the first hole and the second hole are connected to the air source hole. The reversing assembly includes a piston rod that is slidably disposed within the piston chamber. The piston rod is configured to block the first or second hole after sliding, so that the air source hole communicates with the upper air hole through the first hole or with the lower air hole through the second hole.

[0011] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The piston rod slides in the same direction as the vibration assembly, and the piston rod is provided with an upper pusher and a lower pusher that penetrate the piston cavity wall at both ends. When the vibration assembly is configured to reciprocate, the upper and lower push members contact the top and bottom of the vibration space, respectively, and are subjected to thrust to drive the piston rod to slide.

[0012] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The first hole and the second hole are distributed along the axial direction of the piston cavity; The piston chamber wall also has a third hole and a fourth hole that communicate with the upper air hole and the lower air hole respectively; The piston rod has an upper groove and a lower groove on its outer wall. The upper groove forms an upper communicating chamber with the wall of the piston cavity, and the lower groove forms a lower communicating chamber with the wall of the piston cavity. The piston rod slides to either the upper or lower connected position. When the piston rod is in the upper communication position, the first hole communicates with the third hole through the upper communication chamber, and at this time the piston rod blocks the second hole; When the piston rod is in the lower connecting position, the second hole communicates with the fourth hole through the lower connecting chamber, and at this time the piston rod blocks the first hole.

[0013] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The piston chamber wall also has an exhaust port, which communicates with the outside. The piston rod also has a central groove on its outer wall, and the central groove and the piston cavity wall form a centrally connected chamber. When the piston rod is in the upper connected position, the lower air hole is connected to the exhaust hole through the middle connected chamber to discharge the gas in the lower space. At this time, the piston rod blocks the fourth hole. When the piston rod is in the lower connecting position, the upper air hole communicates with the exhaust hole through the middle connecting chamber to discharge the gas in the upper space. At this time, the piston rod blocks the third hole.

[0014] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The vibration space has a first rod and a second rod arranged in parallel. Both ends of the first rod and the second rod are connected to the top and bottom of the vibration space, and both the first rod and the second rod pass through the vibration assembly; The first rod has an air intake channel that is connected to the air source hole, and the second rod has an air outlet channel that is connected to the exhaust hole.

[0015] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The main body also has an upper air inlet chamber and a lower air outlet chamber. The vibration space is located between the upper air inlet chamber and the lower air outlet chamber. The main body has an air inlet pipe that communicates with the upper air inlet chamber. The upper air inlet chamber is connected to the air inlet channel. The lower air outlet chamber has an air outlet hole on its cavity wall, and the lower air outlet chamber is connected to the air outlet channel.

[0016] For example, at least one embodiment of this disclosure provides a pneumatic self-excited vibration type powder material unblocking device. The main body has an upper end and a lower end. The outer surface of the lower end is a conical surface, and several air outlets are evenly distributed along the circumference of the conical surface.

[0017] The beneficial effects of the embodiments of the present invention are as follows: In this invention, the unblocking device is suspended by ropes and placed inside the top opening of the silo (grain silo or coal silo). Then, the reciprocating sliding of the vibrating component drives the main body to vibrate, gradually reaching the bottom opening of the silo. Through continuous vibration, the material blocking the opening of the silo is unblocked, thus achieving the effect of unblocking the material. Compared with manually stirring and unblocking the material from the opening of the silo with machinery, this method is safer, more efficient, and saves manpower. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0023] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-10 As shown, it illustrates a pneumatic self-excited vibration type powder material unblocking device according to an embodiment of the present invention, including a main body 1 and a vibration component 2. The main body 1 has a vibration space 11; the vibration component 2 is reciprocally slidably disposed in the vibration space 11, and the vibration component 2 can drive the main body 1 to vibrate during reciprocating sliding to unblock the material.

[0028] Reference Figure 1 and Figure 3 As shown, the unblocking device is suspended by ropes and placed inside the top opening of the silo (grain silo or coal silo). Then, the reciprocating sliding of the vibrating component 2 drives the main body 1 to vibrate, gradually reaching the bottom opening of the silo. Through continuous vibration, the material blocking the opening of the silo is unblocked, thus achieving the effect of unblocking the material. Compared with manual unblocking by stirring and unblocking from the opening of the silo with machinery, it is safer, more efficient and saves manpower.

[0029] In real-world scenarios involving blockages at the outlets of coal and grain bunkers, traditional manual unblocking methods using augers require operators to be in close contact with the obstructing material, posing significant safety risks. For example, in a coal bunker, if coal becomes severely compacted and lumpy, manual unblocking could cause a large amount of coal to suddenly fall, burying operators and causing serious personal injury. This pneumatic self-excited vibration-type powder material unblocking device, however, is suspended into the bunker through a rope from the top opening. Operators do not need to approach the opening, completely avoiding the risk of burial from sudden material falls and providing reliable safety for operators. This fundamentally improves the hazardous environment for unblocking operations.

[0030] The main body 1 is made of high-strength, corrosion-resistant stainless steel. Stainless steel has excellent corrosion resistance, effectively resisting the erosion of the main body by moisture, acidic substances in coal, and moldy substances that may exist in the grain silo, ensuring the stable operation of the equipment for a long time in harsh environments. At the same time, the high strength of stainless steel can withstand the vibration generated by the vibration components and the external impact that the equipment may be subjected to during the movement of the equipment in the silo, ensuring the integrity and stability of the main structure.

[0031] The unblocking device is lowered into the silo using high-strength ropes. The choice of lifting equipment is crucial. For small silos, a manual winch can be used; it is simple to operate, low-cost, and suitable for situations with limited space and low unblocking frequency. The manual winch must have sufficient load-bearing capacity to easily lift the entire unblocking device. For large silos or scenarios with frequent unblocking operations, an electric hoist should be used. Electric hoists offer higher lifting efficiency and precise lifting control, enabling quick and accurate placement of the device into the designated position within the silo. The lifting capacity of the electric hoist must be selected based on the weight of the unblocking device and the resistance that may need to be overcome.

[0032] One end of the rope is securely fixed to the lifting equipment at the top of the silo. For manual winches, the rope is wound around the winch drum and secured with a special locking device to ensure that the rope does not loosen during lifting. For electric hoists, the rope is connected to the hoist's lifting mechanism via a hook, which should have an anti-disengagement device to prevent the rope from accidentally falling off. The other end of the rope is connected to a lifting ring at the top of the main body 1. During connection, the rope is passed through the lifting ring and secured with rope clips; the number and specifications of the rope clips are determined based on the rope diameter and the load-bearing capacity.

[0033] After the device is smoothly lowered into the silo via ropes, the drive system of the vibration component 2 is activated. The drive system begins to operate, causing the vibration component 2 to reciprocate within the vibration space 11. The reciprocating sliding of the vibration component 2 transmits vibration to the main body 1, thereby causing the main body 1 to generate high-frequency vibration. During the operation of the device, the lifting speed of the device within the silo can be controlled by a controller installed on the lifting equipment. For example, when approaching a heavily clogged area near the bottom opening of the silo, the descent speed can be reduced, allowing the device to remain in that area for a longer period, thus enhancing the vibration's effect on the clogged material. Simultaneously, multiple control buttons can be installed on the operating panel of the lifting equipment to control the device's raising, lowering, and stopping actions, allowing operators to flexibly adjust the device's position according to actual conditions.

[0034] In some examples, the vibration component 2 divides the vibration space 11 into an upper space 12 and a lower space 13; the top and bottom of the vibration component 2 have an upper air hole 21 and a lower air hole 22, respectively, which are used for air discharge. The upper air hole 21 discharges air or the lower air hole 22 discharges air alternately to drive the vibration component 2 to slide back and forth.

[0035] For example, such as Figure 3 and Figure 4As shown, the upper vent 21 and lower vent 22 alternately release air, thereby driving the vibrating component 2 to slide back and forth. There are two ways to achieve this. One way is (at this time, the upper space 12 and the lower space 13 are open, that is, they have exhaust parts) relying on the reaction force of the airflow, the upper vent 21 and lower vent 22 alternately release air to drive it. The other way is (the upper space 12 and the lower space 13 are alternately closed, that is, when the upper vent 21 releases air, the upper space 12 is closed and the lower space 13 is connected to the outside, and when the lower vent 22 releases air, the lower space 13 is closed and the upper space 12 is connected to the outside) relying on the pressure change of the upper space 12 and the lower space 13 caused by the release of air from the upper vent 21 and the lower vent 22 to drive it.

[0036] In some examples, the vibration assembly 2 has an air source port 23 for communicating with an external air source. The air source port 23 is connected to the upper air port 21 or the lower air port 22 via the reversing assembly 3; the vibration assembly 2 has an upward sliding dynamic (see reference). Figure 6 and Figure 7 ) and downward dynamics (refer to Figure 8 and Figure 9 When the reversing component 3 connects the air source hole 23 with the upper air hole 21, air is discharged from the upper air hole 21, and the vibration component 2 is in a downward dynamic; when the reversing component 3 connects the air source hole 23 with the lower air hole 22, air is discharged from the lower air hole 22, and the vibration component 2 is in an upward sliding dynamic.

[0037] For example, refer to Figure 6 As shown, the air source hole 23 is connected to an external air source. The switching component 3 enables the connection to the upper air hole 21 or the lower air hole 22, thereby achieving alternating air output from the upper air hole 21 and the lower air hole 22, and controlling the vibration component 2 to be in an upward sliding dynamic or a downward sliding dynamic.

[0038] In some examples, the vibration assembly 2 has a piston chamber 24, and the wall of the piston chamber 24 has a first hole 31 and a second hole 32, respectively. The first hole 31 and the second hole 32 are respectively used to communicate with the upper air hole 21 and the lower air hole 22. The first hole 31 and the second hole 32 are both connected to the air source hole 23. The reversing assembly 3 includes a piston rod 33, which is slidably disposed in the piston chamber 24. The piston rod 33 is configured to block the first hole 31 or the second hole 32 after sliding, so that the air source hole 23 communicates with the upper air hole 21 through the first hole 31 or with the lower air hole 22 through the second hole 32.

[0039] For example, such as Figure 6 As shown, the piston rod 33 slides in the piston chamber 24 to block the first hole 31 or the second hole 32, thereby realizing the connection and switching between the air source hole 23 and the upper air hole 21 or the lower air hole 22, and thus realizing the alternating air output of the upper air hole 21 and the lower air hole 22.

[0040] In some examples, the piston rod 33 slides in the same direction as the vibration assembly 2, and the piston rod 33 is provided with an upper pusher 34 and a lower pusher 35 that penetrate the wall of the piston cavity 24 at both ends. When the vibration assembly 2 slides back and forth, the upper pusher 34 and the lower pusher 35 contact the top and bottom of the vibration space 11 respectively and are pushed to drive the piston rod 33 to slide.

[0041] For example, such as Figure 6 and Figure 8 As shown, the piston rod 33 slides in the same direction as the vibration assembly 2. Through the contact of the upper pusher 34 and lower pusher 35 with the top and bottom of the vibration space 11, thrust is generated, enabling the piston rod 33 to automatically reverse direction without the need for an additional power source. In the long-term continuous operation of grain and coal bunker unclogging processes, this simplifies the device structure, reduces energy consumption, and minimizes potential failure points caused by excessive components. Furthermore, the close coordination between the movement of the vibration assembly 2 and the reversal of the piston rod 33 ensures timely and accurate gas flow switching, allowing the vibration assembly 2 to move continuously and stably, improving the overall working efficiency and stability of the device, and avoiding a decrease in unclogging effectiveness due to component incoordination.

[0042] In some examples, the first hole 31 and the second hole 32 are distributed along the axial direction of the piston chamber 24; the piston chamber 24 also has a third hole 36 and a fourth hole 37 communicating with the upper air hole 21 and the lower air hole 22 respectively; the piston rod 33 has an upper groove 41 and a lower groove 42 on its outer wall, the upper groove 41 forming an upper communicating chamber 43 with the piston chamber 24, and the lower groove 42 forming a lower communicating chamber 44 with the piston chamber 24; the piston rod 33 is in the upper communicating position after sliding (refer to...). Figure 8 and Figure 9 (as shown) or the lower connected bit (refer to) Figure 6 and Figure 7 (As shown); when the piston rod 33 is in the upper connecting position, the first hole 31 is connected to the third hole 36 through the upper connecting chamber 43, and at this time the piston rod 33 blocks the second hole 32 or the fourth hole 37; when the piston rod 33 is in the lower connecting position, the second hole 32 is connected to the fourth hole 37 through the lower connecting chamber 44, and at this time the piston rod 33 blocks the first hole 31 or the third hole 36.

[0043] For example, such as Figure 6 As shown, by setting the first hole 31, the second hole 32, the third hole 36, the fourth hole 37, and the upper groove 41 and the lower groove 42 on the piston rod 33, an upper connecting chamber 43 and a lower connecting chamber 44 are formed, thereby realizing gas communication and reversing control.

[0044] In some examples, the piston chamber 24 also has an exhaust port 38 on its wall, which communicates with the outside; the piston rod 33 also has a central groove 45 on its outer wall, which forms a centrally connected chamber 46 with the piston chamber 24 wall; when the piston rod 33 is in the upper connected position, the lower vent 22 communicates with the exhaust port 38 through the centrally connected chamber 46 to discharge the gas in the lower space 13, at which time the piston rod 33 blocks the fourth hole 37; when the piston rod 33 is in the lower connected position, the upper vent 21 communicates with the exhaust port 38 through the centrally connected chamber 46 to discharge the gas in the upper space 12, at which time the piston rod 33 blocks the third hole 36.

[0045] For example, such as Figure 6 and Figure 8 As shown, an exhaust port 38 and a central groove 45 are provided to form a centrally connected chamber 46, which enables the vibration component 2 to effectively discharge gas from the upper space 12 or the lower space 13 under different motion states, preventing gas from accumulating in the upper space 12 or the lower space 13, and ensuring that the unblocking operation is carried out continuously and efficiently.

[0046] In some examples, the vibration space 11 has a first rod 51 and a second rod 52 arranged in parallel; both ends of the first rod 51 and the second rod 52 are connected to the top and bottom of the vibration space 11, and both the first rod 51 and the second rod 52 pass through the vibration assembly 2; the first rod 51 has an air inlet channel 511, which is connected to the air source hole 23, and the second rod 52 has an air outlet channel 521, which is connected to the exhaust hole 38.

[0047] For example, such as Figure 6 and Figure 7 As shown, the first rod 51 and the second rod 52 can serve as guides on the one hand, and on the other hand, they can be used to intake air (drive air source) through the air intake channel 511 and exhaust air through the air outlet channel 521 (to relieve pressure and ensure the reciprocating motion of the vibration component 2).

[0048] In some examples, the main body 1 also has an upper air inlet chamber 61 and a lower air outlet chamber 62, the vibration space 11 is located between the upper air inlet chamber 61 and the lower air outlet chamber 62, the main body 1 has an air inlet pipe 63 that communicates with the upper air inlet chamber 61, and the upper air inlet chamber 61 is connected to the air inlet channel 511; the lower air outlet chamber 62 has an air outlet hole 64 on its cavity wall, and the lower air outlet chamber 62 is connected to the air outlet channel 521.

[0049] For example, such as Figure 6 As shown, the air intake pipe 63, the upper air intake chamber 61 and the air intake channel 511 are connected in sequence. An external air source is connected to the air intake pipe 63, thereby realizing the function of the air intake driving the vibration component 2 to slide back and forth. The air outlet channel 521, the lower air outlet chamber 62 and the air outlet 64 are connected in sequence, thereby realizing the function of discharging the gas in the upper space 12 or the lower space 13.

[0050] In some examples, the main body 1 has an upper end and a lower end, the outer surface of the lower end is a conical surface, and a number of air vents 64 are evenly distributed along the circumference of the conical surface.

[0051] For example, such as Figure 1 and Figure 2 As shown, the air outlet 64 is located at the lower end of the main body 1, which can blow air into the blockage material in the chamber. Combined with its own vibration, it can loosen the blockage material and improve the efficiency of unblocking.

[0052] In some examples, the main body 1 has a hanging ring 7, and both the hanging ring 7 and the air intake pipe 63 are located at the upper end of the main body 1. The main body 1 is a rotating body shape, and three hanging rings 7 are evenly arranged along the circumference of the main body 1.

[0053] For example, such as Figure 1 As shown, the lifting ring 7 is designed to facilitate the hoisting of the unblocking device with ropes. The three rings are evenly arranged, which can improve the firmness and stability during hoisting, and make it easier to operate.

[0054] Overall workflow: The rope is connected to the lifting ring 7 to lift the unblocking device and place it in the chamber. The air inlet pipe 63 is connected to the external high-pressure gas through the pipeline. The high-pressure gas enters the vibration component 2 through the air inlet pipe 63, the upper air inlet chamber 61, the air inlet channel 511, and the air source hole 23 in sequence, thereby driving the vibration component 2 to slide back and forth.

[0055] After the high-pressure gas enters the vibration component 2, it realizes the alternating air output or exhaust of the upper air hole 21 and the lower air hole 22 depending on whether the piston rod 33 is in the upper or lower connected position.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
