Description

Technical Field

[0001] This invention relates to the field of bulk material conveying and storage equipment, and in particular to a dredging device for coal storage bunkers. Background Technology

[0002] Coal bunkers are specialized structures used for large-scale coal storage in industrial sites such as coal-fired power plants, coal chemical plants, steel mills, coal mines, and ports. Their main function is to provide a buffer for coal transfer, dispatching, and storage. As an important facility for coal storage, coal bunkers inevitably encounter various problems during long-term use. Representative issues include coal outlet blockage, coal briquettes, coal adhering to the walls, and bunker collapse. These problems not only severely impact production efficiency but also pose significant safety hazards. Taking coal outlet blockage as an example, this is the most direct form of blockage, occurring at the coal outlet of the bunker. Large chunks of coal, clumps of coal, or impurities physically block the narrow outlet, preventing material from passing through. The cause is usually due to inadequate control of the size of the coal entering the bunker or foreign objects falling in during production or transportation. However, in cold regions, high-moisture coal may freeze into large chunks near the outlet, also leading to blockage.

[0003] Given the aforementioned problems, existing technologies generally require manual labor to poke the affected area with long poles from the outside or to clean it from the inside, which carries the risks of working at heights and mechanical injuries.

[0004] Chinese patent application CN120517809A discloses an underground coal bunker unblocking system. This system includes a spiral conveying drill rod, a drill rod drive device, an intelligent monitoring module, and a control module. The drill rod is mounted on the inner wall of the coal bunker, with a gap of less than 10mm between the outer edge of the drill rod blades and the inner wall. The drill rod drive device is connected to the drill rod to drive its rotation. The intelligent monitoring module integrates a pressure sensor array, an infrared coal flow detector, and an image recognition camera. This module monitors the blockage status inside the coal bunker in real time, and the control module dynamically adjusts the speed and direction of rotation of the spiral conveying drill rod based on the monitoring data. This patent application's technical solution uses a spiral conveying drill rod installed inside the coal bunker to unblock the area near the coal outlet when internal blockage is detected, through the rotation control of the drill rod. However, this method places the main working parts of the equipment inside the coal bunker, resulting in complex operating conditions and poor operational stability. Furthermore, the deployment and maintenance of the equipment are also quite difficult.

[0005] Therefore, existing technologies still need improvement to address the issue of unblocking the coal outlet of coal storage bunkers. Summary of the Invention

[0006] In view of the above-mentioned problems existing in the prior art, one aspect of the present invention is to provide a coal storage bunker outlet unblocking device, which is deployed on a base platform near the coal storage bunker outlet and can effectively clean the blockage at the outlet from the outside of the bunker.

[0007] To achieve the above objectives, one aspect of the present invention provides a coal storage bunker outlet unblocking device. The coal storage bunker includes a bunker foundation platform, a pre-embedded foundation, and a main body of the bunker disposed on the foundation platform. The foundation platform has multiple second openings corresponding to those within the main body of the bunker, each second opening forming a coal outlet. A first opening for easy unblocking is provided on the outer wall of each coal outlet. The unblocking device is positioned at a preset angle at the first opening and includes at least a first unblocking device comprising: The first frame includes a first frame body and a sliding base slidably disposed on the first frame body; A vibratory rod unblocking assembly includes a vibratory rod and a vibratory rod conveying mechanism. The vibratory rod conveying mechanism is integrally hinged to the sliding base via a first hinge. It includes a housing and friction wheels disposed within the housing. The friction wheels are arranged opposite each other and are each driven independently by a motor disposed on the housing. The vibratory rod is located between the two oppositely arranged friction wheels and can extend or retract relative to each other under the drive of the motor.

[0008] In this invention, when the friction wheels rotate, they can apply a traction force to the vibrating rod located between the two friction wheels through friction. Simultaneously, by controlling the forward and reverse rotation of the motor, the vibrating rod can vibrate back and forth, clearing blockages. Of course, the vibrating rod has a certain length and can extend directly into the coal outlet from the first opening on the outer wall of the coal outlet.

[0009] As a further improvement, in some embodiments, a first slide rail is provided along the length of the first frame body of the first frame, and a first slider is provided on the first slide rail. The sliding base is slidably mounted on the first frame body via the first slider. By operating the sliding base to slide along the first slide rail, the vibrating rod can be extended and retracted while the vibrating rod conveying mechanism moves "back and forth" as a whole, providing a higher degree of freedom.

[0010] In some improvements, preferably, the sliding base is provided with a rotating gear disk, and the rotating gear disk is provided with a second hinge portion that is hinged to the first hinge portion. By rotating the gear disk, the entire vibrating rod conveying mechanism can be rotated at a large angle, further increasing its degree of freedom. Moreover, the mutual hinge of the first and second hinge portions also enables the overall pitch adjustment of the vibrating rod conveying mechanism.

[0011] Preferably, in this invention, a slot is provided between the two first slide rails arranged opposite each other on the first frame body, and a belt drive mechanism is provided within the slot. The sliding base is connected to the first drive belt of the belt drive mechanism. When the first motor driving the belt drive mechanism is working, it can drive the sliding base to move along the first slide rail.

[0012] Preferably, the friction wheel includes two first friction wheels and two second friction wheels arranged opposite to each other. The housing of the vibration rod conveying mechanism is also provided with a second motor for driving the first friction wheels and a third motor for driving the second friction wheels. The sliding base is also provided with a fourth motor for controlling the rotation of the rotating gear disk.

[0013] In other improvements to the present invention, a second unblocking device may be included, either alone or simultaneously. The second unblocking device is positioned at a preset angle at the first opening and includes: The second frame includes a second frame body and a slide that is slidably mounted on the second frame body; An air cannon assembly includes a high-pressure gas cylinder and a mounting bracket mounted on the slide. A gas pipe connected to the high-pressure gas cylinder passes through the mounting bracket. A nozzle is connected to the outlet end of the gas pipe. An adjustment bracket for adjusting the gas ejection angle is provided on the outlet end. The nozzle is mounted on the adjustment bracket.

[0014] In this embodiment, an air cannon assembly can be used to pneumatically clear blockages in the coal outlet. The overall movement of the slide ensures that the nozzle in the air cannon assembly can extend into the first opening of the coal outlet. At the same time, the adjustable bracket ensures that the nozzle can spray air at an adjustable angle within a certain range.

[0015] Preferably, the second frame also includes end frames and a base frame connected to both ends of the second frame body, forming a trapezoidal frame structure. Second slide rails are provided on opposite sides of the second frame body, and the slide is slidably mounted on the second frame body by a second slider.

[0016] Preferably, the end frame is provided with a first clamp and a second clamp for easy fixing to the coal bunker foundation platform; the second frame body is provided with diagonal bracing.

[0017] Preferably, a drive motor is mounted on the end frame, with a drive wheel at the output end of the drive motor, and a driven wheel is mounted on the base frame. A transmission chain connects the drive wheel and the driven wheel, and the slide is connected to the transmission chain. By controlling the speed and rotation direction of the drive motor, the position of the air cannon assembly on the second frame can be adjusted, facilitating the nozzle to extend into the first opening of the coal outlet for unblocking operations.

[0018] Preferably, the carriage is also equipped with a telescopic motor for controlling the extension and retraction of the air tube and a reduction gear.

[0019] In another improved embodiment of the present invention, a second unblocking device may be included, either alone or simultaneously. The second unblocking device is disposed at the first opening at a preset angle and includes: The second frame includes a second frame body and a slide that is slidably mounted on the second frame body; An air cannon assembly includes a high-pressure gas cylinder mounted on the carriage, an air pipe connected to the high-pressure gas cylinder passing through the free end of the carriage, and a nozzle. The nozzle is also connected to an adjusting bracket, which includes a rotating frame connected to the nozzle and a first gear and a second gear mounted on the rotating frame.

[0020] On the other hand, this invention also provides a coal storage bunker outlet unblocking device. The coal storage bunker includes a bunker foundation platform, a pre-embedded foundation, and a main body of the bunker disposed on the foundation platform. The foundation platform has multiple second openings corresponding to those within the main body of the bunker, each forming a coal outlet. A first opening for easy unblocking is provided on the outer wall of the coal outlet. The unblocking device is positioned at a preset angle at the first opening and is equipped with a guide rail. A first unblocking device and a second unblocking device are slidably mounted on the guide rail. The first unblocking device includes: The first frame includes a first frame body and a sliding base slidably disposed on the first frame body; A vibratory rod unblocking assembly includes a vibratory rod and a vibratory rod conveying mechanism. The vibratory rod conveying mechanism is integrally hinged to the sliding base through a first hinge. It includes a housing and friction wheels disposed within the housing. The friction wheels are arranged opposite to each other and are each driven independently by a motor disposed on the housing. The vibratory rod is located between the two oppositely arranged friction wheels and can extend or retract relative to each other under the drive of the motor. The second unblocking device includes: The second frame includes a second frame body and a slide that is slidably mounted on the second frame body; An air cannon assembly includes a high-pressure gas cylinder and a mounting bracket mounted on the slide. A gas pipe connected to the high-pressure gas cylinder passes through the mounting bracket. A nozzle is connected to the outlet end of the gas pipe. An adjustment bracket for adjusting the gas ejection angle is provided on the outlet end. The nozzle is mounted on the adjustment bracket.

[0021] Compared with existing technologies, the coal outlet unblocking device for coal storage bunkers provided by this invention is installed outside the coal storage bunker, making it easy to install, deploy, and maintain. The operating conditions are more stable compared to the inside of the bunker, resulting in excellent operational stability. Furthermore, by setting up tracks, both mechanical unblocking and automatic unblocking methods can be deployed simultaneously to address different types of blockages. Attached Figure Description

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] These and other features of the invention will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0026] It should also be understood that although the invention has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of the invention, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0027] The above and other aspects, features and advantages of the invention will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0028] In order to achieve the above objectives, one embodiment of the present invention provides a coal storage bunker outlet unblocking device, such as... Figures 1 to 4As shown, it can be used to unclog the coal outlet 1021 of the coal storage bunker 100. Typically, the coal storage bunker 100 includes a bunker foundation platform 102, a pre-embedded foundation 103, and a main body 101 mounted on the foundation platform 102. The foundation platform 102 has multiple second openings 1024 corresponding to those within the main body 101, forming the coal outlet 1021. A first opening 1022 is provided on the outer wall of the coal outlet 1021 to facilitate unblocking. The first opening 1022 is not actually used for material discharge but is used specifically for unblocking. The unblocking device is positioned at a preset angle at the first opening 1022, allowing the working part of the unblocking device to enter the coal outlet for unblocking operations. This unblocking device includes at least a first unblocking device 1, such as... Figures 5 to 7 As shown, the first unblocking device 1 includes: The first frame 11 includes a first frame body 112 and a sliding base 126 slidably disposed on the first frame body 112. In some embodiments, the sliding base 126 is slidably disposed on the first frame body 112 along its length by a first slide rail 111, and a first slider 1261 is disposed on the first slide rail 111, so that the sliding base 126 is slidably disposed on the first frame body 112 via the first slider 1261. By operating the sliding base 126 to slide along the first slide rail 111, the vibrating rod can move "back and forth" as a whole while the vibrating rod is extending and retracting, providing a higher degree of freedom. It is worth noting that this method is only an illustrative example and is not intended to limit the technical solution of the present invention. Furthermore, in the specific sliding control process, the sliding can be achieved by manual control or by motor control, for example, see Appendix Figure 6 and attached Figure 7 As shown, a slot 1121 is provided between the two first slide rails 111 that are arranged opposite each other on the first frame body 112. A belt drive mechanism (not shown in the figure) is provided within the slot 1121, and the sliding base 126 is connected to the first drive belt 114 of the belt drive mechanism. When the first motor 113 that drives the belt drive mechanism is working, it can drive the sliding base 126 to move along the first slide rail.

[0029] In this invention, the working part that actually performs the unblocking function is the vibrating rod unblocking assembly 12, see [link / reference]. Figures 5 to 7As shown, it includes a vibrating rod 13 and a vibrating rod conveying mechanism 121. The vibrating rod conveying mechanism 121 is integrally hinged to the sliding base 126 via a first hinge part 127. It includes a housing and friction wheels disposed within the housing. The friction wheels are arranged opposite each other and are each driven independently by a motor disposed on the housing. The vibrating rod is located between the two oppositely arranged friction wheels and can extend or retract relative to each other under the drive of the motor to clear the coal outlet 1021. In this invention, when the friction wheels rotate, they can apply a traction force to the vibrating rod located between the two friction wheels through friction. At the same time, by controlling the forward and reverse rotation of the motor, the vibrating rod can vibrate back and forth to clear blockages. Of course, the vibrating rod has a certain length and can extend directly into the coal outlet from the first opening on the outer wall of the coal outlet. Specifically, to ensure the working stability of the vibrating rod, preferably, the friction wheel includes two first friction wheels 122 and two second friction wheels 123 arranged opposite each other. The housing of the vibrating rod conveying mechanism 121 is also equipped with a second motor 124 for driving the first friction wheels 122 and a third motor 125 for driving the second friction wheels. The sliding base 126 is also equipped with a fourth motor 128 for controlling the rotation of the rotating gear disk 129. In fact, the two opposing first friction wheels 122 and the two opposing second friction wheels 123 are located on two vertical planes.

[0030] In other improvements, preferably, the sliding base 126 is provided with a rotating gear disk 129, and the rotating gear disk 129 is provided with a second hinge portion 1262 that is hinged to the first hinge portion 127. By rotating the gear disk 129, the vibrating rod conveying mechanism 121 can be rotated at a large angle, further improving its degree of freedom. Moreover, the mutual hinge of the first hinge portion 127 and the second hinge portion 1262 also realizes the overall pitch adjustment of the vibrating rod conveying mechanism 121.

[0031] exist Figures 8 to 10 The figure shows a second unblocking device 2, which can be installed alone or simultaneously with the first unblocking device. The second unblocking device 2 is positioned at a preset angle at the first opening 1022, as shown in the figure, and includes: The second frame 21 includes a second frame body 211 and a slide 226 slidably disposed on the second frame body 211; The air cannon assembly 22 includes a high-pressure gas cylinder 23 and a mounting bracket 222 mounted on the slide 226. An air pipe 221 connected to the high-pressure gas cylinder 23 passes through the mounting bracket 222. A nozzle 225 is connected to the outlet end 223 of the air pipe 221. An adjustment bracket 224 for adjusting the gas ejection angle is provided on the outlet end 223. The nozzle 225 is mounted on the adjustment bracket 224.

[0032] In this embodiment, the blockage at the coal outlet can be pneumatically cleared by an air cannon assembly. The overall movement of the slide 226 ensures that the nozzle 225 in the air cannon assembly 22 can extend into the first opening 1022 of the coal outlet 1021. At the same time, the adjusting bracket 224 ensures that the nozzle 225 can spray air at an adjustable angle within a certain range.

[0033] In the second unblocking device 2, the second frame 21 further includes end frames 212 and a base frame 213 connected to both ends of the second frame body 211, forming a trapezoidal frame structure. Second slide rails 2111 are provided on opposite sides of the second frame body 211, and the slide 226 is slidably mounted on the second frame 21 via second sliders 227. The end frames 212 are provided with first grippers 2121 and second grippers 2122 for easy fixing to the coal bunker foundation platform 102; the second frame body 211 is provided with diagonal braces 2112. Furthermore, a drive motor 214 is provided on the end frames 212, with a drive wheel 215 at the output end of the drive motor 214. A driven wheel 216 is provided on the base frame 213, and a transmission chain connects the drive wheel 215 and the driven wheel 216. The slide 226 is connected to the transmission chain. By controlling the speed and rotation direction of the drive motor 214, the position of the air cannon assembly 22 on the second frame 21 can be adjusted, making it convenient for the nozzle 225 to extend into the first opening 1022 of the coal outlet 1021 for unblocking operations.

[0034] More specifically, in some improvements, the carriage 226 is also equipped with a telescopic motor 228 and a reduction gear 229 for controlling the extension and retraction of the air tube 221.
