Description
Technical Field
[0001] The utility model relates to the technical field of fly ash storage, and in particular to an ash storage device which is convenient for ash discharge. Background Art
[0002] Fly ash is the fine ash collected from the flue gas after coal combustion. As the main solid waste discharged from coal-fired power plants, it has a wide range of uses, mainly including as a concrete admixture, road foundation material, cement products, mine backfill material, soil conditioner, steam generator and foundry sand.
[0003] Since fly ash is in ash form and is not suitable for direct storage in the open air, it is usually stored in a fly ash silo. Although the silo serves as a storage container for fly ash, the fly ash may arch due to its poor fluidity or static electricity between particles during storage. In addition, the fly ash material may become compacted when stored for a long time. Therefore, the fly ash silo may encounter blockage of the discharge port during use. For this reason, the present application proposes an ash storage device that is convenient for ash discharge. Utility Model Content
[0004] Based on the above description, the utility model provides an ash storage device that is convenient for ash discharge, which solves the technical problem that when fly ash is stored in a silo, fly ash is easily arched and compacted, making it inconvenient to discharge the fly ash.
[0005] The utility model solves the above technical problems with the following technical solutions: an ash storage device that is convenient for ash discharge and is used to store fly ash, comprising:
[0006] A silo structure comprising an insulating outer silo and an inner ash storage silo, wherein the inner ash storage silo is disposed on the inner bottom wall of the insulating outer silo, and a top end of the inner ash storage silo extends from the top of the insulating outer silo, with a spacing space between the insulating outer silo and the inner ash storage silo;
[0007] The arch-breaking structure includes a plurality of air bags detachably arranged on the inner wall of the ash storage bin, and a pipe extending from the ash storage bin and communicating with the spacing space is arranged on one side of the air bag;
[0008] The pressure regulating structure includes a telescopic part and a partition, wherein the telescopic part is arranged in the insulated outer bin, and the partition is slidably connected to the outside of the ash storage inner bin, and divides the spacing space into an upper space and a lower space isolated from each other. This partition is installed at the telescopic end of the telescopic part, so that the airbag can cyclically expand and contract when the partition cyclically rises and falls, forming a broken arch for the fly ash in the ash storage inner bin.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Further, the airbag is located at the lower part of the inner ash storage bin and is connected to the lower space. When the partition circulates up and down, the volume of the lower space circulates and becomes larger and smaller, enabling the airbag to circulate and inflate and deflate.
[0011] Further, the telescopic stroke of the telescopic member is less than the minimum height difference between the partition and the airbag.
[0012] Further, the telescopic member is one of a cylinder, an electric push rod or a hydraulic cylinder.
[0013] Further, a number of air supplement packages connected to the upper space are provided on the outer side of the inner ash storage bin. When the volume of the upper space circulates and becomes larger and smaller, the air supplement packages circulate and contract and inflate accordingly.
[0014] Further, a backing plate is slidably connected to the outer side of the connecting pipe. One side of the backing plate away from the inner ash storage bin is a flat surface. A threaded portion is also provided on the outer side of the connecting pipe, and a locking nut threadedly connected to the connecting pipe through the threaded portion is attached to this flat surface.
[0015] Further, an ash discharge pipe passing through the bottom of the heat insulation outer bin is provided at the bottom of the inner ash storage bin. A number of legs for supporting it are welded on the outer side of the heat insulation outer bin, and the legs are erected on the ground, so that there is a height gap between the ash discharge pipe and the ground.
[0016] Further, it further includes a stirring structure for stirring the fly ash in the inner ash storage bin;
[0017] The stirring structure includes a motor, a speed reducer and a stirrer. The motor is fixed to the top cover of the inner ash storage bin by bolts. The output end of the motor is connected to the input end of the speed reducer. The stirrer is assembled at the reduction end of the speed reducer and is located in the inner ash storage bin.
[0018] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:
[0019] 1. For the ash storage device facilitating ash discharge, by adjusting the volume of the upper space and the lower space in the spacing space through the pressure regulating structure, the airbag can be circulated and inflated and deflated, forming arch breaking of the fly ash in the inner ash storage bin for discharging materials.

Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model.
[0028] As Figure 1 and Figure 2 shown, an ash storage device facilitating ash discharge in this embodiment is mainly used for storing fly ash and providing convenient support for ash discharge of fly ash. The ash storage device facilitating ash discharge includes a bin structure 1, an arch - breaking structure 2, and a pressure - regulating structure 3.
[0029] First, considering that in some cold regions, affected by temperature, the fly ash will solidify or agglomerate, which will affect subsequent ash discharge. Therefore, as Figure 2 shown, the bin structure 1 in this embodiment is designed to include an ash - storage inner bin 12 for providing a storage space for fly ash and a heat - insulating outer bin 11 for strengthening heat insulation of the ash - storage inner bin 12. The ash - storage inner bin 12 is arranged on the inner bottom wall of the heat - insulating outer bin 11, and the material of the heat - insulating outer bin 11 is, for example, stainless steel with heat - insulating performance. In this way, the heat - insulating outer bin 11 can be used for strengthening heat - insulation protection, thereby minimizing the occurrence of material solidification or agglomeration.
[0030] The top end of the ash - storage inner bin 12 extends out from the top of the heat - insulating outer bin 11. Specifically, the top of the ash - storage inner bin 12 has a top cover, which fits on the heat - insulating outer bin 11. The top cover of the ash - storage inner bin 12 is, for example, connected to the heat - insulating outer bin 11 by bolts. Moreover, there is a spacing space 13 between the heat - insulating outer bin 11 and the ash - storage inner bin 12. This spacing space 13 can provide space support for the installation of the pressure - regulating structure 3 and can provide normal - state air pressure for the arch - breaking structure 2.
[0031] It should be noted that a dust discharge pipe passing through the bottom of the heat insulation outer bin 11 is fixedly arranged at the bottom of the ash storage inner bin 12. A number of legs for supporting the heat insulation outer bin 11 are welded on the outside of the heat insulation outer bin 11. The legs are erected on the ground, so that there is a height gap between the dust discharge pipe and the ground. In this way, when discharging materials, a container for receiving materials can be placed under the dust discharge pipe to meet the material receiving requirements. Of course, it can be understood that a metal coating, such as an aluminum or silver coating, can also be provided on the ash storage inner bin 12 to provide a smooth surface, which helps to improve the fluidity of the material, reduce the risk of blockage, and facilitate cleaning and maintenance.
[0032] To complete the arch breaking of the fly ash in the ash storage inner bin 12, please refer to Figure 2 and Figure 3 , as shown in the figure, the arch breaking structure 2 in this embodiment includes a number of air bags 21 detachably arranged on the inner wall of the ash storage inner bin 12. A connecting pipe 22 extending from the ash storage inner bin 12 and communicating with the spacing space 13 is fixedly arranged on one side of the air bag 21. In this way, when the air pressure in the air bag 21 is regulated subsequently, the air bag 21 can be cyclically inflated and deflated. During this process, the movement of the air bag 21 can form the arch breaking of the fly ash in the ash storage inner bin 12.
[0033] Regarding the detachable connection relationship between the air bags 21 on the inner wall of the ash storage inner bin 12, as Figure 3 shown, a backing plate 23 fitting on the outer wall of the ash storage inner bin 12 is slidably connected to the outside of the connecting pipe 22. One side of the backing plate 23 away from the ash storage inner bin 12 is a plane. A threaded portion is also arranged on the outside of the connecting pipe 22. A locking nut threadedly connected to the connecting pipe 22 through the threaded portion is fitted on this plane. In this way, the air bag 21 in the arch breaking structure 2 can be detachably locked.
[0034] To enable the air bag 21 to be cyclically inflated and deflated, so as to complete the arch breaking of the fly ash in the ash storage inner bin 12, as Figure 2 shown, the pressure regulating structure 3 includes a telescopic member 31 and a partition plate 32. Among them, the telescopic member 31 is arranged in the heat insulation outer bin 11. The telescopic member 31 is fixed to the inner top wall of the heat insulation outer bin 11 by bolts, for example, and the telescopic member 31 is one of a cylinder, an electric push rod or a hydraulic cylinder. The partition plate 32 is slidably connected to the outside of the ash storage inner bin 12 and divides the spacing space 13 into an upper space and a lower space that are isolated from each other. The partition plate 32 is installed on the telescopic end of the telescopic member 31 by bolts, so that the air bag 21 can be cyclically inflated and deflated when the partition plate 32 cyclically moves up and down, forming the arch breaking of the fly ash in the ash storage inner bin 12.
[0035] It should be noted that the airbag 21 is located at the lower part of the ash storage bin 12 and is connected to the lower space. In this way, when the partition 32 cyclically rises and falls, the volume of the lower space cyclically increases and decreases, allowing the airbag 21 to cyclically swell and shrink, and the telescopic stroke of the telescopic part 31 is less than the minimum height difference between the partition 32 and the airbag 21. In this way, the partition 32 will not form contact with the broken arch structure 2.
[0036] In order to let the workers know that the ash storage equipment that is convenient for ash discharge is in a broken arch state, Figure 1 and 2 As shown, a number of air-supplementing bags 4 connected to the upper space are provided on the outside of the ash storage inner bin 12. When designed in this way, when the volume of the upper space changes, the air-supplementing bags 4 can replenish and store air for the upper space, and when the volume of the upper space cyclically increases and decreases, the air-supplementing bags 4 can cyclically shrink and bulge accordingly. Workers can know whether the ash storage equipment that is convenient for ash discharge is in a broken arch state by penetrating the air-supplementing bags 4.
[0037] During operation, by utilizing the telescopic characteristics of the telescopic member 31, when the telescopic member 31 is started, the operation of the telescopic member 31 can allow the partition 32 to move up and down cyclically. When the partition 32 moves, the overall space of the spacing space 13 is inconvenient, but the volume of the upper space and the lower space in the spacing space 13 will change accordingly. For example, when the partition 32 moves downward, the volume of the lower space decreases and the volume of the upper space increases. When the volume of the lower space decreases, the airbag 21 will bulge. Conversely, when the partition 32 moves back subsequently, the airbag 21 will shrink accordingly. In this way, the airbag 21 cyclically bulges and shrinks, forming a broken arch on the fly ash in the ash storage bin 12.
[0038] In addition, in order to further break the arch and make fly ash easier to discharge, such as Figure 2 As shown, the ash storage device for facilitating ash discharge further includes a stirring structure 5, which is used to stir the fly ash in the ash storage inner bin 12, thereby breaking the arch.
[0039] Specifically, such as Figure 2 As shown, the stirring structure 5 includes a motor 51, a reducer 52 and an agitator 53, wherein the motor 51 is fixed to the top cover of the ash storage bin 12 by bolts, the output end of the motor 51 is connected to the input end of the reducer 52, and the agitator 53 is assembled at the reduction end of the reducer 52 and is located in the ash storage bin 12.
[0040] It should be noted that the agitator 53 is composed of a shaft column and a stirring paddle. The shaft column is assembled at the reduction end of the reducer 52, and there are multiple stirring paddles, which are linearly distributed at equal distances from top to bottom, and the multiple stirring paddles are fixed on the outside of the shaft column.
[0041] During operation, start the motor 51. After being transmitted by the speed reducer 52, the agitator 53 can be made to work. In this way, through agitation treatment, it is possible to prevent the fly ash from aggravating sedimentation and caking, and to break the arch formed by the caked fly ash.
[0042] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
