Description

Technical Field

[0001] The present application relates to the technical field of silo blockage clearing equipment, and in particular to a silo blockage clearing device. Background Art

[0002] Silos are used in various industries such as mining, metallurgy, chemical industry, building materials, machinery, etc. to transport materials. Due to internal friction, deliquescence, electrification, component segregation and other reasons of materials in the silo, "blockage", "arching", "wall hanging" and other phenomena occur, resulting in reduced silo capacity and even silo blockage, which in turn causes feeder failures such as material cutoff, affecting production and even causing safety accidents. In order to prevent silo blockage, the inner wall of the silo needs to be cleaned from time to time.

[0003] At present, the commonly used means to solve blockages are manual dredging or installing a silo wall vibrator on the outside of the silo wall. Manual dredging not only has a long cleaning cycle but also a poor cleaning effect; the silo wall vibrator vibrates the silo wall to gradually separate the materials adhering to the silo wall to achieve the purpose of unblocking, but the vibration force of the silo wall vibrator is relatively large, and long-term use can easily cause fatigue damage to the silo wall, thereby causing the silo wall to crack. Utility Model Content

[0004] The embodiment of the present application provides a silo blockage clearing device for solving the problem that when materials are arched and blocked in the silo, the manual clearing cycle is long and the cleaning effect is poor, and the use of a silo wall vibrator easily causes fatigue damage to the silo wall.

[0005] To achieve the above purpose, the present application provides a silo blockage clearing device, comprising:

[0006] A vibrating lining plate is located on the inner side of the silo wall of the silo, the silo wall is provided with an opening corresponding to the vibrating lining plate and smaller in size than the vibrating lining plate, and the upper end of the vibrating lining plate is hinged to the inner side of the silo wall through a hinge;

[0007] A plurality of ultrasonic vibrators are evenly arranged on a side of the vibration lining plate facing outward of the opening; and

[0008] The ultrasonic generator is connected in series with each of the ultrasonic vibrators.

[0009] Optionally, the plurality of ultrasonic vibrators are arranged in at least two rows in the circumferential direction of the warehouse wall, two adjacent ultrasonic vibrators in the same row are arranged at equal intervals in the height direction of the warehouse wall, and the ultrasonic vibrators in two adjacent rows are staggered in the circumferential direction of the warehouse wall.

[0010] Optionally, the silo blockage clearing device further comprises a flexible shielding sheet, wherein the flexible shielding sheet covers between the edges around the vibrating lining plate and the inner side of the silo wall.

[0011] Optionally, the flexible shielding sheet is a strip rubber sheet, which covers between the edge of the vibration lining and the inner side of the warehouse wall, and is fixed to the edge of the vibration lining and the inner side of the warehouse wall by adhesive.

[0012] Optionally, the amplitude-changing cone at the front end of the ultrasonic vibrator is fixed to the side of the vibration lining plate facing outward from the opening by adhesive bonding.

[0013] Optionally, a stud is welded on the side of the vibration lining plate facing the outside of the opening, a threaded hole is provided on the amplitude-changing cone at the front end of the ultrasonic vibrator, and the amplitude-changing cone at the front end of the ultrasonic vibrator is threadedly connected to the stud.

[0014] Optionally, the silo blockage clearing device further includes a material sensor and a controller, wherein the material sensor is disposed in a discharge port of the silo, and the controller is electrically connected to the material sensor and the ultrasonic generator, respectively.

[0015] The beneficial effect of the silo blockage clearing device provided by the present application is that compared with the prior art, the silo blockage clearing device of the present application includes a vibrating lining, a plurality of ultrasonic vibrators and an ultrasonic generator. In actual application, an opening with a size smaller than the size of the vibrating lining can be set at a position in the silo where blockage, arching and wall hanging are prone to occur, and the vibrating lining is placed in the silo at a position corresponding to the opening on the silo wall. The upper end of the vibrating lining is hinged to the inner side of the silo wall by a hinge, and a plurality of ultrasonic vibrators are evenly arranged on the side of the vibrating lining facing the outside of the opening. The ultrasonic generator and each ultrasonic vibrator are connected in series in sequence, and the high-frequency vibration of each ultrasonic vibrator is controlled by the ultrasonic generator to drive the vibrating lining to vibrate, thereby generating a disturbance to the blocked material, causing the blocked material to fall, and completing the removal of the arching, blockage and sticking of the material in the silo. Since the ultrasonic vibrator mainly applies vibration to the vibrating lining, it is not easy to damage the silo wall, thereby extending the service life of the silo.

[0032] In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically defined. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0033] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0034] As described in the background technology, in the related technology, the commonly used means to solve the blockage of silo are manual dredging or installing a silo wall vibrator on the outside of the silo wall. Manual dredging not only has a long cleaning cycle but also a poor cleaning effect; the silo wall vibrator vibrates the silo wall to gradually separate the materials adhering to the silo wall to achieve the purpose of unblocking, but the vibration force of the silo wall vibrator is relatively large, and long-term use can easily cause fatigue damage to the silo wall, thereby causing the silo wall to crack.

[0035] In order to solve the above problems, the embodiments of the present application provide a silo blockage clearing device, such as Figure 1 As shown, the silo blockage clearing device comprises a vibrating lining plate 100, a plurality of ultrasonic vibrators 300 and an ultrasonic generator 400. The vibrating lining plate 100 is located on the inner side of the silo wall 11 of the silo 10. The silo wall 11 is provided with an opening 12 corresponding to the vibrating lining plate 100 and smaller in size than the vibrating lining plate 100. The upper end of the vibrating lining plate 100 is hinged to the inner side of the silo wall 11 through a hinge 200. The plurality of ultrasonic vibrators 300 are evenly arranged on the side of the vibrating lining plate 100 facing the outside of the opening 12. The ultrasonic generator 400 is connected in series with each ultrasonic vibrator 300 in sequence.

[0036] In the embodiment of the present application, when the silo blockage clearing device is actually used, an opening 12 with a size smaller than that of the vibrating lining 100 is set at a position where the silo 10 is prone to blockage, arching and wall hanging, and the vibrating lining 100 is placed in the silo 10 at a position corresponding to the opening 12 on the silo wall 11. The upper end of the vibrating lining 100 is hinged to the inner side of the silo wall 11 through a hinge 200, and a plurality of ultrasonic vibrators 300 are evenly arranged on the side of the vibrating lining 100 facing the outside of the opening 12. The ultrasonic generator 400 is connected in series with each ultrasonic vibrator 300 in sequence, and the ultrasonic generator 400 controls each ultrasonic vibrator 300 to vibrate at a high frequency, driving the vibrating lining 100 to vibrate, thereby generating a disturbance to the blocked material, causing the blocked material to fall, and completing the removal of the arching, blockage and sticking of the material in the silo 10. Since the ultrasonic vibrator 300 mainly applies vibration to the vibrating lining 100, it is not easy to damage the silo wall 11, thereby extending the service life of the silo 10.

[0037] The hinge 200 is preferably a flexible hinge. “The ultrasonic generator 400 and each ultrasonic vibrator 300 are connected in series in sequence” means: the positive electrodes of multiple ultrasonic vibrators 300 are connected in series through a wire and then connected to the positive electrode of the ultrasonic generator 400; the negative electrodes of multiple ultrasonic vibrators 300 are connected in series through another wire and then connected to the negative electrode of the ultrasonic generator 400, and the power supply end of the ultrasonic generator 400 is connected to an external power supply, and the ultrasonic generator 400 can change the vibration amplitude of the ultrasonic vibrator 300.

[0038] In addition, it is understandable that for the same silo 10, there are usually multiple locations where blockage, arching and wall hanging are prone to occur. Figure 1 As shown, a plurality of vibrating liners 100 can be provided in the silo blockage clearing device, and the ultrasonic vibrators 300 on all the vibrating liners 100 are sequentially connected in series and then connected to the ultrasonic generator 400.

[0039] It should be noted that the shape of the vibration lining plate 100 needs to correspond to the shape of the warehouse wall 11, and the material is preferably a metal plate. For example, when the warehouse wall 11 is cylindrical, the vibration lining plate 100 is also an arc-shaped plate; when the warehouse wall 11 is a square cylinder, the vibration lining plate 100 needs to be set to a flat plate.

[0040] In one embodiment, if Figure 1 As shown, a plurality of ultrasonic vibrators 300 are arranged in at least two rows in the circumferential direction of the warehouse wall 11 , two adjacent ultrasonic vibrators 300 in the same row are arranged at equal intervals in the height direction of the warehouse wall 11 , and ultrasonic vibrators 300 in two adjacent rows are arranged alternately in the circumferential direction of the warehouse wall 11 .

[0041] The ultrasonic vibrators 300 are arranged as above, and the installation positions and quantities are reasonably planned to ensure a better vibration clearing effect.

[0042] In one embodiment, if Figure 1 and Figure 2 As shown, the silo blockage clearing device further includes a flexible shielding sheet 500 , which covers between the edges around the vibrating liner 100 and the inner side of the silo wall 11 .

[0043] The flexible shielding sheet 500 can prevent the material from entering the gap between the vibrating lining plate 100 and the silo wall 11 and leaking outward from the opening 12. In addition, the flexible shielding sheet 500 has a certain deformation ability and does not affect the vibration of the vibrating lining plate 100.

[0044] Specifically, the flexible shielding sheet 500 is a strip of rubber sheet, which covers between the edge of the vibration lining plate 100 and the inner side of the warehouse wall 11, and is fixed to the edge of the vibration lining plate 100 and the inner side of the warehouse wall 11 by adhesive.

[0045] In one embodiment, if Figure 1 and Figure 2 As shown, the amplitude-changing cone at the front end of the ultrasonic vibrator 300 is fixed to the side of the vibration lining 100 facing the outside of the opening 12 by adhesive bonding. This connection method is simple and reliable, which is conducive to increasing the contact area between the ultrasonic vibrator 300 and the vibration lining 100, thereby ensuring reliable transmission of vibration.

[0046] In another embodiment, not shown in the figure, a stud is welded on the side of the vibration lining plate facing the outside of the opening, a threaded hole is provided on the amplitude-changing cone at the front end of the ultrasonic vibrator, and the amplitude-changing cone at the front end of the ultrasonic vibrator is threadedly connected to the stud. This connection method is also simple and reliable.

[0047] In one embodiment, if Figure 1 As shown, the silo blockage clearing device further includes a material sensor 600 and a controller 700. The material sensor 600 is disposed in the discharge port of the silo 10, and the controller 700 is electrically connected to the material sensor 600 and the ultrasonic generator 400, respectively.

[0048] When the amount of material falling decreases or no material falls, it indicates that a blockage has occurred in the silo 10. The material sensor 600 transmits the detected material blockage signal to the controller 700. The controller 700 controls the ultrasonic generator 400 to output an electrical signal of ultrasonic frequency, driving the ultrasonic vibrator 300 on the vibrating lining 100 to vibrate at a high frequency, causing the vibrating lining 100 to generate ultrasonic vibrations. The material in the silo 10 is shaken off by the ultrasonic vibration of the vibrating lining 100, thereby automatically realizing the blockage clearing operation.

[0049] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
