Description

An acoustic vibration device for unclogging coal bunkers Technical Field

[0001] This utility model relates to the technical field of coal bunker unblocking equipment, and in particular to an acoustic vibration device for unblocking coal bunkers. Background Technology

[0002] In the coal production and transportation process, coal bunkers, as key facilities for temporary coal storage and auxiliary transportation, are crucial to the stable operation of the entire coal production process. However, in actual application, coal bunkers are prone to problems such as coal blockage and coal spillage, which bring many severe challenges to coal enterprises.

[0003] Once coal bunkers experience blockages or coal spillage, it severely disrupts the normal transportation of coal, thereby affecting subsequent production and mining operations. The shapes of coal spillages vary, commonly including bridge-shaped, funnel-shaped, arch-shaped, and fireplace-shaped. Blockages are mostly concentrated within 2 meters above the coal gate. Initially, a thin layer of material will adhere to a certain area within this range. As time goes by, the amount of material adhered increases, and the friction gradually increases. Subsequently, the material will extend along the axial or radial direction, and the thickness will gradually increase, eventually forming bridges and blockages of different shapes, which will block the coal conveying channel and prevent normal unloading.

[0004] Traditional methods of clearing blockages, such as manually poking the coal, are not only inefficient but also pose high safety risks. While using mechanical tools can improve efficiency to some extent, they are often insufficient to completely resolve complex blockages and may even damage the coal bunker structure.

[0005] Therefore, it is necessary to provide an acoustic vibration device for clearing blockages in coal bunkers to solve the above-mentioned technical problems. Summary of the Invention

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First Embodiment

[0025] Please refer to Figure 1, which is a structural schematic diagram of the first embodiment of the acoustic vibration device for clearing blockages in a coal bunker provided by this utility model. The acoustic vibration device for clearing blockages in a coal bunker includes: a gas storage tank 1, with an air inlet connector 12 fixedly installed on the top of one side of the gas storage tank 1, and an air inlet valve 13 fixedly installed at the input end of the air inlet connector 12;

[0026] A sound generator 2 is fixedly installed at the output end of the gas storage tank 1. A motor 21 is fixedly installed on one side of the sound generator 2. An air balloon valve 22 is fixedly installed at the output end of the sound generator 2. A conical tube 23 is fixedly installed at the output end of the air balloon valve 22. A Helmholtz resonant cavity 24 is fixedly installed at the output end of the conical tube 23.

[0027] A pressure gauge 11 is fixedly installed on the top of the gas storage tank 1.

[0028] The pressure gauge 11 allows users to easily monitor the pressure inside the gas tank 1 during use.

[0029] Both the gas storage tank 1 and the motor 21 are equipped with support components 3 at their bottoms.

[0030] The working principle of the acoustic vibration device for unclogging coal bunkers provided by this utility model is as follows:

[0031] When using this acoustic vibration device to clear blockages in a coal bunker, first open the inlet valve 13 and fill the gas tank 1 with gas through the inlet connector 12. Observe the pressure gauge 11 on top of the gas tank 1 to monitor the gas pressure. Once the pressure reaches a suitable value, close the inlet valve 13. Next, start the motor 21, which drives the generator 2. The compressed gas in the gas tank 1, after being processed by the generator 2, is output through the outlet valve 22. As the gas passes through the cone tube 23, its special shape accelerates and concentrates the gas, allowing it to enter the Helmholtz resonant cavity 24 more efficiently. The Helmholtz resonant cavity 24 generates sound waves of a specific frequency under the impact of the gas. These sound waves propagate into the surrounding space. When the device approaches the blockage in the coal bunker, the sound waves are transmitted to the blocked coal. The vibrational energy of the sound waves can break down the adhesion and friction between the coal particles, loosening the blockage and thus clearing the coal bunker.

[0032] Compared with related technologies, the acoustic vibration device for clearing blockages in coal bunkers provided by this utility model has the following beneficial effects:

[0033] The system utilizes a combination of components including a gas storage tank 1, a sound generator 2, a motor 21, a cone tube 23, and a Helmholtz resonant cavity 24. When in use, the energy of sound waves can quickly act on large areas of clogged coal, eliminating the need for manual cleaning and significantly increasing the speed of unclogging. It also avoids the high-risk operation of manually entering the coal bunker for unclogging. Furthermore, it effectively clears coal bunker blockages of various shapes and degrees, including bridge-shaped, funnel-shaped, arch-shaped, and fireplace-shaped blockages. The sound waves vibrate the coal, breaking down the blockage structure and solving the problem of complex blockages that traditional mechanical tools struggle to clean, without damaging the coal bunker structure.

[0034] Second Embodiment

[0035] Referring to Figures 2, 3, and 4, based on the first embodiment of this application which provides an acoustic vibration device for clearing blockages in coal bunkers, the second embodiment of this application proposes another acoustic vibration device for clearing blockages in coal bunkers. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the separate implementation of the first embodiment.

[0036] Specifically, the second embodiment of this application provides an acoustic vibration device for clearing blockages in a coal bunker, wherein the support assembly 3 includes a base plate 31, a support frame 32 is fixedly installed on the top of the base plate 31, an extension frame 33 is slidably connected to the top of the outer side of the support frame 32, a rotating shaft 34 is rotatably connected to the inside of one side of the extension frame 33, worm gears 35 are fixedly installed at both ends of the outer side of the rotating shaft 34, worm wheels 36 are meshed on both sides of the two worm gears 35, a threaded rod 37 is fixedly installed inside the worm wheel 36, and a threaded sleeve 38 is threadedly connected to the outer side of the threaded rod 37.

[0037] The top of the threaded rod 37 is rotatably connected to the top of the inner side of the extension frame 33, and the bottom of the threaded sleeve 38 is fixedly installed on the top of the base plate 31.

[0038] A handle 39 is fixedly installed at one end of the rotating shaft 34, and a support base 30 is rotatably connected to the outer side of the rotating shaft 34. The top of the support base 30 is fixedly installed on the top of the inner side of the extension frame 33.

[0039] The top of the extension frame 33 is fixedly installed to the bottom of the gas storage tank 1 and the motor 21, respectively.

[0040] A rotating shaft 34 is rotatably connected inside one side of the extension frame 33, and worm gears 35 are fixedly installed at both ends of its outer side. The worm gears 35 and the rotating shaft 34 are integrally formed to ensure the reliability of the transmission. Threaded rods 37 are fixedly installed inside the four worm wheels 36. The threaded rods 37 are connected to the worm wheels 36 by a key to ensure that the threaded rods 37 can rotate synchronously when the worm wheels 36 rotate. A threaded sleeve 38 is threadedly connected to the outer side of the threaded rod 37. The bottom of the threaded sleeve 38 is fixedly installed on the top of the base plate 31. Through this threaded connection, the rotational motion of the worm wheels 36 is converted into the up-and-down linear motion of the threaded rods 37.

[0041] Furthermore, through the self-locking characteristic between the worm 35 and the worm wheel 36, after being adjusted to a suitable height, it can limit the extension frame 33.

[0042] The working principle of the acoustic vibration device for unclogging coal bunkers provided by this utility model is as follows:

[0043] When installing the device, since a slot for installing the Helmholtz resonant cavity 24 is provided at a specific location in the coal bunker, if the Helmholtz resonant cavity 24 cannot accurately enter the coal bunker through the slot during installation, the user can rotate the handle 39. The handle 39 drives the shaft 34 to rotate, and the worms 35 at both ends of the outer side of the shaft 34 rotate accordingly. The worms 35 mesh with the worm wheel 36, thereby driving the worm wheel 36 to rotate. The threaded rod 37 fixedly installed inside the worm wheel 36 also rotates. Since the threaded rod 37 is threadedly connected to the threaded sleeve 38, and the bottom of the threaded sleeve 38 is fixed on the base plate 31, and the top of the threaded rod 37 is rotatably connected to the top of the inner side of the extension frame 33, the threaded rod 37 will move up and down inside the threaded sleeve 38 when it rotates, thereby realizing the extension frame 33 sliding up and down along the top of the outer side of the support frame 32. The top of the extension frame 33 is fixedly installed to the bottom of the gas storage tank 1 and the motor 21 respectively. This allows the overall height of the device to be adjusted so that the Helmholtz resonant cavity 24 can be accurately aligned with the installation groove on the coal bunker and successfully installed in the appropriate position for subsequent coal bunker unblocking work.

[0044] Compared with related technologies, the acoustic vibration device for clearing blockages in coal bunkers provided by this utility model has the following beneficial effects:

[0045] Through the cooperation of structures such as the base plate 31, support frame 32, extension frame 33, rotating shaft 34, worm 35, worm wheel 36, threaded rod 37 and threaded sleeve 38, the height of the device can be flexibly adjusted during use. This effectively solves the problem that the Helmholtz resonant cavity 24 is difficult to install accurately due to the difference in the position of the coal bunker installation slot during the installation process, and improves the convenience and accuracy of the device installation.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
