Description

[0045] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0047] like Figures 1 to 4 As shown, the present application provides an automatic silo clearing system 1, comprising:

[0048] A silo 1, multiple sets of air cannons 2, multiple sets of vibration motors 3, a belt scale 4, and a controller 5. Multiple sets of air cannons 2 are installed on the outer wall of the silo 1; the nozzles 21 of multiple sets of air cannons 2 are connected to the silo 1; multiple sets of vibration motors 3 are installed on the outer wall of the silo 1; multiple sets of air cannons 2 and multiple sets of vibration motors 3 are arranged alternately along the height direction of the silo 1; a belt scale 4 is installed at intervals from the bottom of the silo 1 and is used to transport and weigh the materials discharged from the silo 1. The controller 5 is signal-connected to the belt scale 4, multiple sets of air cannons 2, and multiple sets of vibration motors 3. The belt scale 4 can convert the acquired material weight information into a first signal; the controller 5 can acquire the first signal and, based on the first signal, control the multiple sets of air cannons 2 and multiple sets of vibration motors 3 to start or stop working.

[0049] Specifically, the silo 1 provides storage space for materials, ensuring the continuity and stability of material supply, and ensuring that sufficient materials are available for subsequent processes at any time. The silo 1 has a storage space, a feed port, and a discharge port. The feed port and the discharge port are respectively connected to the storage space, and the storage space is used to store materials. The feed port is set at the top of the silo 1, and the discharge port is set at the bottom of the silo 1. The discharge port can be directly opposite the belt scale 4 so that the material discharged from the discharge port can fall completely onto the belt scale 4. The silo 1 can be cylindrical or prismatic as a whole, etc.

[0050] Multiple sets of air cannons 2 can generate high-pressure air to impact blocked material within silo 1, loosening the material and clearing the blockage. The automatic silo clearing system 1 can also include a bracket. This bracket must possess a certain strength and stability and can be fixed to silo 1 via bolts. Alternatively, if both the bracket and silo 1 are made of metal, the bracket and silo 1 can be welded. Multiple sets of air cannons 2 can be fixed to the bracket via bolts, welding, or other methods.

[0051] The outer wall of the silo 1 is provided with a mounting hole that communicates with the storage space, and the mounting hole is adapted to the nozzle 21 of the air cannon 2. Each set of air cannons 2 may also include a first flange and a second flange. The first flange can be welded to the outer wall of the silo 1, with the mounting hole located on the inner side of the first flange; the second flange is sleeved onto the nozzle 21. During installation, the nozzle 21 of the air cannon 2 is partially extended into the storage space, and the first and second flanges are connected by bolts to ensure the stability of the connection. Each set of air cannons 2 may also include a sealing gasket, which is placed between the first and second flanges to ensure the sealing of the connection. The nozzle 21 can eject gas horizontally.

[0052] Multiple groups of air cannons 2 can be arranged linearly along the first direction; alternatively, multiple groups of air cannons 2 can be arranged staggered along the first direction. The present application preferably arranges multiple groups of air cannons 2 staggered along the first direction so that high-pressure gas can be sprayed into the interior of the silo 1 from multiple angles, thereby improving the success rate and efficiency of clearing blockages. Each group of air cannons 2 can include one or more air cannons 2. When each group of air cannons 2 includes multiple air cannons 2, the multiple air cannons 2 can be arranged at intervals to increase the impact area of ​​the high-pressure gas and ensure the clearing effect.

[0053] Multiple sets of vibration motors 3 can generate vibrations, which are transmitted to the material inside through the wall of the silo 1, loosening the blocked material. The vibration motors 3 can be welded to the outer wall of the silo 1; alternatively, the vibration motors 3 can be connected to the outer wall of the silo 1 through brackets.

[0054] Multiple groups of vibration motors 3 can be arranged linearly along the first direction; alternatively, multiple groups of vibration motors 3 can be arranged staggered along the first direction. The present application preferably arranges multiple groups of vibration motors 3 staggered along the first direction to increase the vibration range and improve the success rate and efficiency of clearing blockages. Each group of vibration motors 3 can include one or more vibration motors 3. When each group of vibration motors 3 includes multiple vibration motors 3, the multiple vibration motors 3 can be arranged at intervals to increase the vibration range and ensure the clearing effect.

[0055] The belt scale 4 receives material discharged from the discharge port of the silo 1 and conveys it to the next production process. The belt scale 4 accurately measures the weight of the material discharged from the silo 1. By monitoring changes in the material's weight in real time, it provides important information for the controller 5 to determine the discharge status of the silo 1. If the silo 1 experiences an abnormality such as a blockage, the weight change will be reflected in the measurement data from the belt scale 4. The belt scale 4 can be connected to the controller 5 via a wired or wireless signal. The belt scale 4 converts the acquired material weight information into a first signal and transmits this signal to the controller 5.

[0056] The controller 5 has preset values ​​stored in it, and by comparing the acquired first signal with the preset value range, the unloading situation of the silo 1 is determined. If the first signal is lower than the preset value, the controller 5 determines that the silo 1 has a material blockage problem and controls the multiple groups of air cannons 2 and the multiple groups of vibration motors 3 to work. If the first signal is greater than or equal to the preset value, the controller 5 determines that the silo 1 is normal and controls the multiple groups of air cannons 2 and the multiple groups of vibration motors 3 to stop working. The controller 5 can control the multiple groups of air cannons 2 and the multiple groups of vibration motors 3 to work synchronously; or, the controller 5 can control the multiple groups of air cannons 2 and the multiple groups of vibration motors 3 to work at intervals of a certain time, etc. The control method of the controller 5 can be realized by those skilled in the art by simple improvements on the existing basis without the need for creative work.

[0057] The air outlet ends of the multiple groups of air cannons 2 can be provided with electromagnetic valves, and the controller 5 can be connected to the electromagnetic valves via wired signals or wireless signals. The controller 5 can also be connected to the multiple groups of vibration motors 3 via wired signals or wireless signals.

[0058] The air cannon 2, the vibration motor 3, the belt scale 4 and the controller 5 can all be obtained through market purchase.

[0059] The automatic silo blockage clearing system 1 provided in the present application is characterized by arranging belt scales 4 at intervals at the bottom of the silo 1. The material discharged from the silo 1 falls onto the belt scales 4. The belt scales 4 can continuously weigh the material while conveying the material, obtain the weight information of the material, and convert the weight information into a first signal; the controller 5 can automatically control the multiple groups of air cannons 2 and multiple groups of vibration motors 3 to work or stop working based on the first signal, without the need for manual inspection and visual observation, which greatly improves the timeliness of discovering blockages and ensures that the silo 1 can be cleared in time; and, since the multiple groups of air cannons 2 and multiple groups of vibration motors 3 are alternately arranged along the height direction of the silo 1, the two work together, which greatly improves the clearing effect, ensures the stability of material discharge from the silo 1, and thus ensures the continuity of subsequent production.

[0060] like Figure 1 and Figure 2 As shown, the silo 1 includes:

[0061] The first sub-silo 11 is cylindrical;

[0062] The second sub-silo 12 is in a truncated cone shape. The first end of the first sub-silo 11 is connected to the first end of the second sub-silo 12. The second end of the second sub-silo 12 is spaced apart from the belt scale 4.

[0063] The inner diameter of the second sub-silo 12 gradually decreases from the first end to the second end, multiple groups of air cannons 2 are arranged on the outer wall of the second sub-silo 12 , and multiple groups of vibration motors 3 are arranged on the outer wall of the second sub-silo 12 .

[0064] Specifically, the storage space includes a first sub-storage space and a second sub-storage space that are interconnected. The first sub-silo 11 has a first sub-storage space capable of accommodating a large amount of material. The second sub-silo 12 has a second sub-storage space. The first end of the first sub-silo 11 and the first end of the second sub-silo 12 can be welded. The feed port is located at the second end of the first sub-silo 11, and the discharge port is located at the second end of the second sub-silo 12.

[0065] The inner diameter of the second sub-silo 12 gradually decreases from the first end to the second end, increasing the flow rate of the material and improving the efficiency of material discharge. Multiple air cannons 2 and vibration motors 3 are installed on the outer wall of the second sub-silo 12 to effectively prevent blockage of the second sub-silo 12, promote the flow and loosening of the material, and ensure smooth and stable material discharge.

[0066] like Figure 2 and Figure 3 As shown, each group of the air cannon 2 includes:

[0067] The gas storage tank 22 is arranged on the outer wall of the second sub-silo 12; the first end of the nozzle 21 is connected to the gas outlet end of the gas storage tank 22, and the second end of the nozzle 21 extends into the second sub-silo 12; the second end of the nozzle 21 is bent toward the second end face of the second sub-silo 12 at a preset angle to form a bending portion, and the preset angle is greater than 0 degrees and less than or equal to 90 degrees.

[0068] Specifically, the nozzle 21 and the outlet end of the gas storage tank 22 can be sealed together via a flange or a quick-connect connector. The specific bending angle of the bent portion can be specifically designed based on the second sub-silo 12. For example, when the second sub-silo 12 is tilted at a 45-degree angle, the preset angle can also be 45 degrees. This allows the gas to be ejected from the nozzle 21 and impact the material downward along the tilted direction of the inner wall of the second sub-silo 12, thereby improving the energy utilization of the gas, enhancing the clearing effect, and preventing falling material from clogging the nozzle 21.

[0069] like Figure 1 and Figure 2 As shown, each group of the air cannon 2 also includes:

[0070] A bearing member 23 is provided on the outer wall of the second sub-silo 12 and is used to support the gas storage tank 22;

[0071] The limiting member 24 is connected to the supporting member 23. The limiting member 24 cooperates with the outer wall of the second sub-bin 12 to form an enclosure structure. The gas tank 22 is arranged in the enclosure structure, and the enclosure structure is used to limit the gas tank 22 from falling.

[0072] Specifically, the supporting member 23 is in the shape of a plate. When the gas tank 22 is cylindrical, the supporting member 23 can be in the shape of an arc-shaped plate to better fit the surface of the gas tank 22. The supporting member 23 can be made of metal, and the supporting part of the side wall can be welded to the outer wall of the second sub-silo 12. The limiting member 24 can be in the shape of a plate or a rod, etc. The limiting member 24 and the supporting member 23 can be connected by snapping or welding. The limiting member 24 can be in contact with or spaced from the outer wall of the second sub-silo 12. When the limiting member 24 is spaced from the outer wall of the second sub-silo 12, the spacing between the two should be designed according to the size of the gas tank 22 to prevent the gas tank 22 from rolling out from the spacing. The gas tank 22 is arranged on the inner side of the enclosure structure, which can effectively prevent the gas tank 22 from falling and ensure the personal health of the staff.

[0073] like Figure 1 and Figure 2 As shown, each group of the air cannon 2 also includes:

[0074] A first hanging lug 25 is provided on the outer wall of the gas storage tank 22;

[0075] A rigging 26 , wherein a first end of the rigging 26 is connected to the first hanging ear 25 , and the rigging 26 is used to prevent the gas tank 22 from falling.

[0076] Specifically, the first hanging lug 25 can be connected to the outer wall of the gas storage tank 22 by welding or bolting. The number of the first hanging lug 25 can be one or more. When the number of the first hanging lug 25 is more than one, the multiple first hanging lugs 25 can be spaced apart on the outer wall of the gas storage tank 22 to improve the stability of the connection.

[0077] The lock can be made of steel wire rope, chain, etc. The first end of the lock can be connected to the first hanging ear 25 by means of a hook, a buckle, etc., and the second end of the lock can be connected to the top of the factory building by means of a buckle, a buckle, etc. Or,

[0079] The second hanging ear 27 is connected to the second end of the rigging 26; the second hanging ear 27 is arranged on the outer wall of the first sub-silo 11; and / or the second hanging ear 27 is arranged on the outer wall of the second sub-silo 12, and the second hanging ear 27 is located between the first sub-silo 11 and the gas tank 22.

[0080] Specifically, the second hanging lug 27 can be connected to the outer wall of the first sub-silo 11 and / or the outer wall of the second sub-silo 12 by welding or bolting. The second end of the lock can be connected to the second hanging lug 27 by a snap or buckle. The number of the second hanging lugs 27 can be the same as the number of the first hanging lugs 25.

[0081] The combination of the first hanging ear 25, the rigging 26 and the second hanging ear 27 can be used in combination with the bearing member 23 and the limiting member 24 to form a double protection for the gas tank 22. Even if the bearing member 23 and the limiting member 24 fail, the rigging 26 can effectively prevent the gas tank 22 from falling, thereby ensuring the personal safety of the staff and the normal operation of the equipment.

[0082] like Figure 1 As shown, each group of the air cannons 2 includes at least three air cannons 2, and the at least three air cannons 2 in each group are arranged at equal intervals on the outer wall of the second sub-silo 12 along a first circular trajectory; the axis of the second sub-silo 12 passes through the center of the first circular trajectory; and / or,

[0085] Multiple air cannons 2 and vibration motors 3 are evenly spaced along a circular path, impacting and vibrating the clogged material within silo 1 from different directions, covering a wider area and significantly improving the blockage removal effect. The evenly spaced arrangement ensures that the air cannons 2 and vibration motors 3 have a more even effect on silo 1. Furthermore, this even distribution helps maintain the balance of silo 1, making it more stable.
