Description

Technical Field

[0001] This invention relates to the field of coal bunker technology, and in particular to a coal bunker anti-blocking and anti-collapse device. Background Technology

[0002] A coal bunker is a vertical silo facility at the bottom of a coal mine used for temporary storage of coal. It typically consists of a bunker body and is equipped with a coal discharge gate and a coal feeder. The top of the bunker has a coal inlet, and the bottom narrows to include a coal outlet (also known as a coal chute). The coal bunker serves as a buffer between coal production and transportation processes. Blockage and collapse are common problems at the bottom of the bunker. Blockage is mainly caused by coal adhesion, excessive moisture, or uneven particle size, resulting in bulging or arching. Collapse is often caused by high moisture content in the coal, where moisture mixes with coal and other materials to form coal gangue sludge, leading to instability and collapse. Blockage and collapse pose significant hazards, seriously affecting the safety of workers and equipment.

[0003] Existing coal bunker anti-clogging measures mostly rely on external vibrating motors or manual unblocking, which are energy-intensive and have inconsistent effectiveness. Anti-collapse measures often employ independent drainage systems, which are complex in structure and usually located outside the bunker (before the coal inlet or after the coal outlet). Once coal with high moisture content enters the bunker, it is difficult to drain it in time. Furthermore, traditional coal bunkers typically only have a single anti-clogging or anti-collapse function. Therefore, there is an urgent need for a device that integrates anti-clogging, anti-collapse, and energy-saving features. Summary of the Invention

[0004] The main objective of this invention is to propose a coal bunker anti-blocking and anti-collapse device, which aims to provide an integrated anti-blocking, anti-collapse, and energy-saving device to solve the problems that existing coal bunker anti-blocking measures mostly rely on external vibration motors or manual dredging, which have high energy consumption and unstable effects. The anti-collapse measures mostly adopt independent drainage systems, which have complex structures and are usually located outside the bunker. Once coal with high water content enters the bunker, it is difficult to drain it in time.

[0005] To achieve the above objectives, the coal bunker anti-blocking and anti-collapse device proposed in this invention includes a bunker body and an anti-blocking screen mechanism. A coal outlet is formed at the bottom of the inner cavity of the bunker body, and the coal outlet gradually narrows along the direction from the top wall to the bottom wall of the bunker body. A drainage channel is provided on the inner wall of the coal outlet, and the drainage channel communicates with the external space. The anti-blocking screen mechanism has a screen body, which is disposed inside the coal outlet and elastically connected to the inner wall of the coal outlet. The drainage channel is oriented towards the screen body.

[0006] In one embodiment, the anti-clogging screen mechanism further includes a support and an elastic connector, the support being connected to the inner wall of the coal outlet, and the elastic connector connecting the support to the screen body.

[0007] In one embodiment, the anti-clogging screen mechanism further comprises a first elastic support component and a second elastic support component; one end of the first elastic support component is fixedly connected to the inner wall of the coal outlet, and the other end of the first elastic support component is hinged to the bracket; both ends of the second elastic support component are respectively hinged to the inner wall of the coal outlet and the bracket; the second elastic support component is located between the first elastic support component and the bottom wall of the hopper; the screen body is set at an angle to the inner wall of the coal outlet, and the bracket is configured to rotate around the hinge point between the bracket and the first elastic support component, so that the angle between the screen body and the inner wall of the coal outlet increases or decreases.

[0008] In one embodiment, the first elastic support assembly includes a spring and two mounting seats. A sleeve and a sliding rod are respectively formed on each of the two mounting seats. The sleeve is slidably fitted onto the sliding rod. The spring is fitted over the sleeve and the sliding rod, with both ends of the spring abutting against the two mounting seats. One mounting seat is fixedly connected to the inner wall of the coal outlet, and the other mounting seat is hinged to the support. Alternatively, the second elastic support assembly includes a spring and two mounting seats. A sleeve and a sliding rod are respectively formed on each of the two mounting seats. The sleeve is slidably fitted onto the sliding rod. The spring is fitted over the sleeve and the sliding rod, with both ends of the spring abutting against the two mounting seats. The two mounting seats are hinged to the support and the inner wall of the coal outlet, respectively.

[0009] In one embodiment, the anti-clogging screen mechanism further includes a vibration generator, which is disposed on the support.

[0010] In one embodiment, the outer wall of the silo is provided with a water collecting component, and a water collecting trough is formed on the water collecting component. The water collecting component is arranged around the outer wall of the silo, and the water collecting trough is arranged facing the drainage channel.

[0011] In one embodiment, the water collection component is detachably connected to the tank body; and / or, the water collection component is provided with a drainage window, and a shielding component is movably covered on the drainage window.

[0012] In one embodiment, a filter element is provided in the drainage channel, and the filter element is aligned with the inner wall of the coal outlet.

[0013] In one embodiment, the screen body has screen holes that are elongated and gradually narrow along the coal flow direction.

[0014] In one embodiment, the coal bunker anti-blocking and anti-collapse device includes a plurality of anti-blocking screen mechanisms, which are arranged in a ring array.

[0015] The coal bunker anti-blocking and anti-collapse device proposed in this invention includes a bunker body and an anti-blocking screen mechanism. A coal outlet is formed at the bottom of the inner cavity of the bunker body, gradually narrowing from the top wall to the bottom wall of the bunker body. A drainage channel is provided on the inner wall of the coal outlet, communicating with the external space. The anti-blocking screen mechanism has a screen body located inside the coal outlet and elastically connected to the inner wall of the outlet. The drainage channel faces the screen body. By setting the anti-blocking screen mechanism at the coal outlet at the bottom of the coal bunker, the gravity of the coal flow triggers the screen body to vibrate when the coal gate is opened, which can disperse and break up coal blocks and prevent moisture-laden coal blocks from adhering to the inner wall of the bunker body, thus preventing blockage. Simultaneously, the screen body can also intercept or slow down the flow of coal blocks while allowing moisture to pass through, achieving water-coal separation. The water screened out is directly discharged from the bunker body through the drainage channel, avoiding the risk of coal collapse. This device has a simple structure, is energy-saving, and eliminates the limitations of traditional coal bunkers that only offer single anti-blocking or anti-collapse measures.

[0036] This invention proposes a coal bunker anti-blockage and anti-collapse device 100.

[0037] Please see Figure 1 and Figure 5 In one embodiment of the present invention, the coal bunker anti-blocking and anti-collapse device 100 includes a bunker body 1 and an anti-blocking screen mechanism 2. A coal outlet 1a is formed at the bottom of the inner cavity of the bunker body 1. The coal outlet 1a is gradually narrowed along the direction from the top wall to the bottom wall of the bunker body 1. A drainage channel 1b is provided on the inner wall of the coal outlet 1a, and the drainage channel 1b communicates with the external space. The anti-blocking screen mechanism 2 has a screen body 21, which is disposed in the coal outlet 1a and elastically connected to the inner wall of the coal outlet 1a. The drainage channel 1b is arranged facing the screen body 21. A coal discharge gate 200 and a coal feeder 300 are arranged sequentially below the coal outlet 1a. The specific structure of the coal discharge gate 200 and the coal feeder 300 is not part of the improvement of the present invention, and therefore will not be described in detail.

[0038] In this embodiment, the anti-clogging screen mechanism 2 includes a screen body 21, which is disposed inside the coal outlet 1a and elastically connected to the inner wall of the coal outlet 1a. Optionally, the screen body 21 can be a plate-like structure with screen holes 21a on the plate surface, or it can be a mesh structure with mesh holes formed thereon. For example, the screen body 21 can be made of high-strength, wear-resistant metal plate or wire to adapt to the impact and friction of coal blocks, while ensuring that the screen body 21 has sufficient elasticity to generate vibration under the gravity of the coal flow. The shape of the screen body 21 is adapted to the bin 1 so as to cover a larger area of ​​the inner wall of the coal outlet 1a. Common coal bins are cylindrical or square-shaped, and are reinforced concrete or steel structures. The following uses cylindrical or square-shaped coal bins as examples. The coal outlet 1a at the bottom of the cylindrical coal bin is conical, and the inner wall of the coal outlet 1a is arc-shaped. Therefore, the shape of the screen body 21 can be adapted to be fan-shaped and the screen body 21 can be bent to form an arc surface. The coal outlet 1a at the bottom of the cylindrical coal bunker is trapezoidal in shape, and the inner wall of the outlet 1a is flat. Therefore, the shape of the screen body 21 can be adapted to be rectangular or trapezoidal. This allows the screen body 21 to adapt to the shape of the inner cavity of the bunker 1, thereby covering a larger area of ​​the inner wall of the outlet 1a, and avoiding motion interference between the screen body 21 and the bunker 1, which would affect the vibration of the screen body 21. It should be noted that the screen body 21 is elastically connected to the inner wall of the outlet 1a. After the gate is opened, under the influence of the coal's own weight and flow, the screen body 21 will also vibrate and collide with the coal. Therefore, a certain space is set between the screen body 21 and the inner wall of the outlet 1a to avoid motion interference between the screen body 21 and the bunker 1 when it vibrates. For example, the elastic connection between the screen body 21 and the inner wall of the outlet 1a can be achieved by setting an elastic element. Specifically, the elastic element can be a spring 241, a spring 241 steel bracket 22, etc., and the inner wall of the outlet 1a and the screen body 21 are connected by the elastic element. A support 22 can be further provided, which can be connected to the screen body 21 through an elastic element and fixed to the inner wall of the coal outlet 1a. Alternatively, the support 22 can be fixedly connected to the screen body 21 and connected to the inner wall of the coal outlet 1a through an elastic element.

[0039] A drainage channel 1b is installed on the inner wall of the coal outlet 1a and faces the screen body 21. It is used to promptly drain the water screened by the screen body 21 from the silo 1, preventing water accumulation and coal breakage. Specifically, in this embodiment, the drainage channel 1b is located below the screen body 21, with one end of the drainage channel 1b closest to the inner cavity of the silo 1 facing the screen body 21. This maximizes the collection of water screened by the screen body 21 and improves drainage efficiency. The drainage channel 1b extends through the silo 1 from the inner wall of the coal outlet 1a to the outer wall of the silo 1, connecting the inner cavity of the silo 1 with the external space to ensure smooth water flow. The inner wall of the drainage channel 1b can be provided with a corrosion-resistant isolation layer or coating. A corrosion-resistant metal or plastic tubular structure or a corrosion-resistant paint can be applied to the inner wall of the drainage channel 1b to adapt to the long-term moisture erosion environment and prevent corrosion of the silo 1. The drainage channel 1b can extend along the direction of gravity for drainage or be perpendicular to the inner wall of the coal outlet 1a for processing. To improve drainage efficiency, the number of drainage channels 1b can be increased and arranged in an array. It should be noted that the screen body 21 is located above the drainage channel 1b. After separating the coal from the water, the screen body 21 can block some of the coal, reducing contact between the coal and the periphery of the drainage channel 1b, thus reducing the probability of coal sticking to the wall. The coal falling from the screen holes 21a is also dispersed, reducing the probability of coal sticking together. Fine coal powder mixed with water can be directly discharged from the drainage channel 1b, thus preventing blockage. Furthermore, a filter structure can be installed at the inlet of the drainage channel 1b to prevent coal or coal slurry from entering the drainage channel 1b, further reducing the risk of blockage.

[0040] In summary, this embodiment utilizes an anti-clogging screen mechanism 2 installed at the coal outlet 1a at the bottom of the coal bunker. When the coal discharge gate 200 opens, the gravity of the coal flow triggers the screen body 21 to vibrate, which disperses and breaks up coal lumps, preventing moisture-laden coal lumps from adhering to the inner wall of the bunker 1 and thus preventing blockage. Simultaneously, the screen body 21 can intercept or slow down the flow of coal lumps while allowing moisture to pass through, achieving water-coal separation. The water screened out is directly discharged from the bunker 1 through the drainage channel 1b, avoiding the risk of coal collapse. This device has a simple structure, is energy-efficient, and overcomes the limitations of traditional coal bunkers that only offer single-function anti-clogging or anti-collapse measures.

[0041] Further, please refer to Figure 1 and Figure 6 In one embodiment of the present invention, the anti-blocking screen mechanism 2 also has a support 22 and an elastic connector 23. The support 22 is connected to the inner wall of the coal outlet 1a, and the elastic connector 23 connects the support 22 and the screen body 21.

[0042] In this embodiment, the support 22 is connected to the inner wall of the coal outlet 1a, serving a fixing and supporting function to ensure the stable installation of the anti-blocking screen mechanism 2 in the coal bunker. The support 22 can be fixedly connected to the inner wall of the coal outlet 1a by welding, fasteners, etc., or an elastic connection structure can be set between the support 22 and the inner wall of the coal outlet 1a to achieve a shock absorption effect, reducing the vibration transmitted from the screen body 21 to the bunker body 1. The support 22 can adopt a frame structure and can be made of high-strength metal or alloy materials to adapt to the harsh environment inside the coal bunker and ensure sufficient support strength. The elastic connector 23 connects the support 22 and the screen body 21. Its main function is to enable the screen body 21 to vibrate under the gravity of the coal flow, while providing a certain amount of elastic support to prevent damage to the screen body 21 due to excessive vibration. The structure of the elastic connector 23 can be a spring 241 or other elastic elements. Its selection and size can be designed according to the impact force of the coal flow and the vibration requirements of the screen body 21; this embodiment does not impose any limitations on this. It should be noted that multiple elastic connectors 23 can be set, evenly distributed around the screen body 21 or symmetrically distributed on both sides of the screen body 21, to ensure that the screen body 21 can generate uniform vibration.

[0043] In summary, the support 22 provides a fixing point for the elastic connector 23 and the screen body 21 to facilitate installation onto the inner wall of the coal outlet 1a. The elastic connector 23 connects the screen body 21 to the support 22, enabling the screen body 21 to vibrate under the action of the elastic connector 23. This ensures that the screen body 21 can effectively vibrate, disperse, and break up coal blocks under the gravity of the coal flow, while preventing coal blocks from sticking to the inner wall of the bin 1.

[0044] Further, please refer to Figure 3 and Figure 5 In one embodiment of the present invention, the anti-blocking screen mechanism 2 further includes a first elastic support component 24A and a second elastic support component 24B; one end of the first elastic support component 24A is fixedly connected to the inner wall of the coal outlet 1a, and the other end of the first elastic support component 24A is hinged to the bracket 22; both ends of the second elastic support component 24B are respectively hinged to the inner wall of the coal outlet 1a and the bracket 22; the second elastic support component 24B is located between the first elastic support component 24A and the bottom wall of the silo 1; the screen body 21 is set at an angle to the inner wall of the coal outlet 1a, and the screen body 21 is configured to rotate around the hinge point between the screen body 21 and the first elastic support component 24A, so that the angle between the screen body 21 and the inner wall of the coal outlet 1a increases or decreases.

[0045] In this embodiment, the sidewall of the coal outlet 1a is inclined. Both the first elastic support component 24A and the second support component are located on the sidewall of the coal outlet 1a, with the first elastic support component 24A positioned above the second elastic support component 24B. One end of the first elastic support component 24A is fixedly connected to the inner wall of the coal outlet 1a, and the other end is hinged to the bracket 22. Both ends of the second elastic support component 24B are hinged to the inner wall of the coal outlet 1a and the bracket 22, respectively. The heating effect of the first elastic support component 24A and the second support component further enhances the shock absorption effect of the bracket 22 and provides additional elastic support. The first elastic support component 24A and the second support component can use a spring 241 or other elastic element to provide elastic force, and fixed structures can be provided at both ends of the spring 241 to achieve a hinged or fixed connection. Thus, the bracket 22 can rotate around the hinge point between the bracket 22 and the first elastic support component 24A, allowing the bracket 22 to automatically rotate and avoid obstruction under the weight of the coal, providing more space for the coal to fall and preventing blockage. Specifically, the screen body 21 is set at an angle to the inner wall of the coal outlet 1a, meaning both the screen body 21 and the inner wall of the coal outlet 1a are sloped. The slope of the screen body 21 is relatively gentler than that of the inner wall of the coal outlet 1a. Furthermore, the screen body 21 is configured to rotate around the hinge point between the screen body 21 and the first elastic support component 24A, allowing the angle between the screen body 21 and the inner wall of the coal outlet 1a to automatically adjust according to the coal flow conditions, increasing or decreasing the angle. Simultaneously, the screen body 21 can still vibrate under the gravity of the coal flow, dispersing and breaking up coal chunks to prevent blockage. For example, when there is a large amount of coal, the support 22 rotates under the gravity of the coal, and the first elastic support component 24A and the second elastic support component 24B work together to provide a shock absorption effect. The screen body 21 can also vibrate under the gravity and flow of the coal.

[0046] Further, please refer to Figure 5 In one embodiment of the present invention, the first elastic support assembly 24A includes a spring 241 and two mounting seats 242. A sleeve 2421 and a sliding rod 2422 are respectively formed on the two mounting seats 242. The sleeve 2421 is slidably fitted onto the sliding rod 2422. The spring 241 is fitted over the sleeve 2421 and the sliding rod 2422, and both ends of the spring 241 abut against the two mounting seats 242. One mounting seat 242 is fixedly connected to the inner wall of the coal outlet 1a, while the other mounting seat... 242 is hinged to the support 22; and / or, the second elastic support assembly 24B includes a spring 241 and two mounting seats 242, on which a sleeve 2421 and a slide rod 2422 are respectively formed. The sleeve 2421 is slidably sleeved on the slide rod 2422, and the spring 241 is sleeved on the sleeve 2421 and the slide rod 2422. The two ends of the spring 241 abut against the two mounting seats 242 respectively. The two mounting seats 242 are respectively hinged to the support 22 and the inner wall of the coal outlet 1a.

[0047] In this embodiment, both the first elastic support assembly 24A and the second elastic support assembly 24B include a spring 241 and two mounting seats 242. A sleeve 2421 and a sliding rod 2422 are respectively formed on the two mounting seats 242. The sleeve 2421 is slidably fitted onto the sliding rod 2422, and the spring 241 is fitted over the sleeve 2421 and the sliding rod 2422, with both ends of the spring 241 abutting against the two mounting seats 242. This allows the first elastic support assembly 24A and the second elastic support assembly 24B to provide stable elastic support and shock absorption. That is, through the cooperation of the sliding rod 2422 and the sleeve 2421, the spring 241 is guided to extend and retract axially, preventing radial deformation of the spring 241, thereby ensuring the stability and reliability of the elastic support assembly. Furthermore, one mounting base 242 of the first elastic support component 24A is fixedly connected to the inner wall of the coal outlet 1a, and the other mounting base 242 of the first elastic support component 24A is hinged to the bracket 22. The two mounting bases 242 of the second elastic support component 24B are respectively hinged to the inner wall of the coal outlet 1a and the bracket 22, so that the bracket 22 can rotate around the hinge point between the bracket 22 and the first elastic support component 24A. Under the action of the gravity of the coal, the bracket 22 can rotate to avoid displacement, providing more space for the coal to fall and preventing blockage.

[0048] Further, please refer to Figure 7 and Figure 8 In one embodiment of the present invention, the anti-blocking screen mechanism 2 also has a vibration generator 25, which is mounted on the support 22.

[0049] In this embodiment, the introduction of the vibration generator 25 is intended to provide additional vibration power when the amount of coal is large and the vibration of the screen body 21 caused by the gravity of the coal alone is insufficient to meet the requirements, so as to ensure that the screen body 21 can vibrate effectively and prevent blockage and collapse.

[0050] The vibration generator 25 can be pneumatic or electric. A pneumatic vibration generator 25 uses compressed air to generate vibration, offering advantages such as simple structure, fast response, and convenient maintenance. An electric vibration generator 25 uses a motor to drive vibration, offering advantages such as adjustable vibration frequency and amplitude, and high control precision. The main technical function of the vibration generator 25 is to assist the screen body 21 in vibrating when the coal quantity is large, ensuring that the screen body 21 can effectively disperse and break up coal lumps, preventing coal lumps from adhering to the inner wall of the bin 1, thereby preventing bin blockage and collapse. The vibration generator 25 is mounted on the support 22. When the coal quantity is large, the vibration generator 25 is activated, causing the support 22 to vibrate, which in turn drives the screen body 21 to vibrate, thus assisting the screen body 21 in generating vibration. This ensures that when the coal quantity is large, the screen body 21 can obtain sufficient vibration energy to effectively disperse and break up coal lumps, preventing bin blockage and collapse. For example, as shown... Figure 8 As shown, Figure 8An electric vibration generator 25 is provided, including a drive motor 251 and an eccentric block 252. The housing of the drive motor 251 is connected to a bracket 22, and the shaft of the drive motor 251 is connected to the eccentric block 252. The eccentric block 252 is arranged in a fan shape. When the drive motor 251 drives the eccentric block 252 to rotate, it causes vibration. The vibration generator 25 can also be pneumatic, for example, by setting a vibrating hammer on the piston of a cylinder. The reciprocating motion of the cylinder drives the vibrating hammer to strike the bracket 22 to generate vibration.

[0051] Further, please refer to Figure 3 and Figure 4 In one embodiment of the present invention, the outer wall of the silo 1 is provided with a water collecting member 12, and a water collecting trough 12a is formed on the water collecting member 12. The water collecting member 12 is arranged around the outer wall of the silo 1, and the water collecting trough 12a is arranged facing the drainage channel 1b.

[0052] In this embodiment, by installing a water collection component 12 on the outer wall of the coal bunker 1, the drainage effect is enhanced, ensuring that the water in the coal bunker can be discharged in a timely manner and preventing the bunker from collapsing. Specifically, the water collection component 12 is installed on the outer wall of the coal bunker 1 to collect the water discharged from the drainage channel 1b and guide the water to a designated drainage area, such as a drainage pool. The water collection component 12 can be designed as annular, frame-shaped, or spiral, depending on the shape of the outer wall of the coal bunker 1, so that the water collection component 12 can surround the outer wall of the coal bunker 1 to correspond to the multiple drainage channels 1b provided on the coal bunker 1. A water collection trough 12a is formed on the water collection component 12, and the water collection trough 12a is positioned facing the drainage channel 1b to receive the water flowing out of the drainage channel 1b. The material of the water collection component 12 can be a corrosion-resistant metal or plastic to adapt to an environment that is subject to long-term water erosion. Furthermore, a cover can be added to the water collection component 12 to prevent water evaporation from affecting the working environment. The cover, the water collection component 12, and the outer wall of the chamber 1 enclose a drainage space. This drainage space is connected to the inner cavity of the chamber 1 through the drainage channel 1b and is eventually connected to a drainage pool or other places.

[0053] Furthermore, in one embodiment of the present invention, the water collection component 12 is detachably connected to the tank body 1; and / or, the water collection component 12 is provided with a drainage window, and a shielding component is movably covered on the drainage window.

[0054] In this embodiment, considering that a small amount of coal dust may enter the drainage trough through the drainage channel 1b and gradually form coal sludge to clog the drainage trough, the design of the water collection component 12 is further optimized to facilitate sludge removal, specifically as follows: the water collection component 12 is detachably connected to the silo body 1, for example, by bolts, clips, or other detachable connectors. This design allows the water collection component 12 to be easily removed from the silo body 1 for easy sludge removal and maintenance, and / or, the water collection component 12 is provided with a dredging window, which can be located on the side wall or bottom wall of the water collection trough 12a. The dredging window is movably covered with a shielding component, such as a detachable cover plate or a movable door. In this way, without stopping work, water can be flushed into the water collection trough 12a or dredging tools can be inserted through the dredging window for sludge removal, preventing coal dust and coal sludge from clogging the drainage trough.

[0055] Further, please refer to Figure 5 In one embodiment of the present invention, a filter element 11 is provided in the drainage channel 1b, and the filter element 11 is aligned with the inner wall of the coal outlet 1a.

[0056] In this embodiment, a filter element 11 is provided inside the drainage channel 1b, and the filter element 11 is aligned with the inner wall of the coal outlet 1a. The main function of the filter element 11 is to prevent coal sludge from entering the drainage channel 1b, ensuring the unobstructed flow of the drainage channel 1b. The filter element 11 can be made of high-strength, corrosion-resistant metal materials, such as stainless steel, and the pore size is designed according to the size of the coal sludge particles to effectively filter the coal sludge particles. The filter element 11 can adopt a mesh structure or have multiple holes in a plate structure. The filter element 11 is located inside the drainage channel 1b, aligned with the inner wall of the coal outlet 1a. Even if the filter element 11 is located at the entrance of the drainage channel 1b, the surface of the filter element 11 facing the coal outlet 1a is coplanar with the inner wall of the coal outlet 1a, thus reducing the residue of coal sludge in the drainage channel 1b.

[0057] Further, please refer to Figure 6 and Figure 7 In one embodiment of the present invention, the screen body 21 has screen holes 21a, which are elongated and gradually narrow along the coal flow direction.

[0058] In this embodiment, the screen body 21 has screen holes 21a, which are elongated and gradually narrow along the coal flow direction. It should be noted that since the screen body 21 is inclined downward, the coal flow direction is inclined downward along the surface of the screen body 21. The large diameter end of the screen hole 21a is at the top and the small diameter end is at the bottom. The main function of this design is to adapt to the separation requirements of coal blocks of different sizes. At the same time, it is convenient for larger coal blocks to be stuck in the screen holes 21a. The larger coal blocks are broken in the screen holes 21a by the gravity of the coal and the vibration of the screen body 21, which further improves the anti-clogging effect.

[0059] Furthermore, in one embodiment of the present invention, the coal bunker anti-blocking and anti-collapse device 100 includes a plurality of anti-blocking screen mechanisms 2, which are arranged in a ring array.

[0060] In this embodiment, the coal bunker anti-blocking and anti-collapse device 100 includes multiple anti-blocking screen mechanisms 2, which are arranged in a ring array to form a petal-like structure. The main function of this design is to improve screening efficiency, increase space utilization, and ensure that a larger area is covered within a limited space. Simultaneously, when the anti-blocking screen mechanisms 2 rotate around the first elastic support component 24A, the movement between the multiple anti-blocking screen mechanisms 2 will not interfere with each other. For example, the coal bunker anti-blocking and anti-collapse device 100 may include two, three, four, or other numbers of anti-blocking screen mechanisms 2. Common coal bunkers are cylindrical or square-shaped. Taking a cylindrical coal bunker as an example, two anti-clogging screen mechanisms 2 can be installed symmetrically about the coal outlet 1a. The anti-clogging screen mechanism 2 includes a support 22 and a screen body 21. To adapt to the curved shape of the inner wall of the bunker body 1, the support 22 and the screen body 21 are bent to form a shape that fits the curved surface of the inner wall of the bunker body 1. Considering that the area of ​​a single anti-clogging screen mechanism 2 is too large and is prone to deformation after being impacted by the coal flow, affecting structural safety, it can be further subdivided, for example, by setting three, four, or more anti-clogging screen mechanisms 2. The area of ​​each anti-clogging screen mechanism 2 is reduced, but the total coverage area remains unchanged. The same principle applies to other shapes of coal bunkers, so it will not be described in detail here.

[0061] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
