Description

Technical Field

[0001] This invention relates to the field of sleeve cleaning technology, and in particular to a compensating cleaning rapping device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this invention and does not constitute prior art.

[0003] In the existing smelting field, in order to improve energy utilization and environmental awareness, the recovery and utilization of converter flue gas, similar to converter steelmaking, has developed into a complete production chain. Among them, supporting processes such as total waste heat recovery and dry dust removal have also been gradually developed. During the normal smelting production stage of the converter, the collected flue gas has a high temperature, large gas flow rate, high dust content, and high content of combustible gases. In order to prevent high-temperature spark particles carried in the flue gas from igniting the flue gas and causing an explosion, it is necessary to complete the collection of high-temperature particles before waste heat recovery to avoid explosions during the total waste heat recovery stage. Therefore, the current main solution is to use a sleeve-shaped particle collection device with inclined plate settling technology to solve this problem.

[0004] The sleeve-shaped particle collection device based on inclined plate settling technology mainly uses dry gravity settling technology to separate particles. The sleeve has multiple layers of inclined plates to increase the flue gas flow area and capture ignition particles, eliminating the risk of flue gas being ignited and exploding. However, this device also has the problem of internal ash accumulation that needs to be cleaned frequently. Existing rapping ash removal devices generally use hammer rapping ash removal devices, but the rapping frequency of this device is too low, and the rapping force cannot be effectively transmitted to the ash accumulation area. The high-pressure impact vibration ash removal device developed later is more complex and relies on high pressure equipment. It also has high requirements for high pressure sealing and is prone to damage.

[0005] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figures 1 to 4 As shown, the present invention provides a compensating dust removal rapping device, which includes:

[0040] A horizontal cantilever 1 that can be connected to a vibration source has a vibration transmission component 2 detachably connected to one end, and a cooling chamber 11 is formed inside the horizontal cantilever 1.

[0041] The compensation mechanism 3 is sealed and fitted outside the horizontal cantilever 1. The compensation mechanism 3 includes an outer housing 31 and an inner housing 32 that passes through the outer housing 31. One end of the outer housing 31 is connected to the horizontal cantilever 1, and the other end is sealed and connected to the inner housing 32. A cooling channel 321 is formed between the inner housing 32 and the horizontal cantilever 1. The cooling channel 321 is connected to the cooling chamber 11.

[0042] The compensating dust removal rapping device of the present invention uses a horizontal cantilever 1 to transmit the vibration force of the vibration source. The horizontal cantilever 1 acts directly on the impact point through the vibration transmission component 2, which can achieve high-efficiency transmission of vibration force. At the same time, by injecting cooling medium into the cooling chamber 11 of the horizontal cantilever 1 and the cooling channel 321 formed between the inner box 32 and the horizontal cantilever 1, the problem of heat deformation caused by continuous operation of the horizontal cantilever 1 in a high-temperature environment can be effectively reduced.

[0043] Specifically, the horizontal cantilever 1 is generally a rectangular cavity structure. The inner box 32 and the outer box 31 of the compensation mechanism 3 are square boxes with different radial dimensions. They are sequentially fitted onto the horizontal cantilever 1 from the inside to the outside along the direction away from the horizontal cantilever 1. The length of the horizontal cantilever 1 and the length of the compensation mechanism 3 can be set according to the actual installation position and the required compensation amount, and are not limited here. In this embodiment, the inner housing 32 of the compensation mechanism 3 is located between the outer housing 31 and the horizontal cantilever 1. At one end of the compensation mechanism 3, the inner housing 32 and the outer housing 31 are sealed together, while at the other end, the outer housing 31 is connected to the horizontal cantilever 1. A flow loop 311 is formed between the inner housing 32 and the outer housing 31. At least one cooling gas outlet 13 is provided on the horizontal cantilever 1 corresponding to the flow loop 311. The cooling chamber 11 is connected to the flow loop 311 through at least one cooling gas outlet 13. The flow loop 311 is connected to the cooling channel 321 formed between the inner housing 32 and the horizontal cantilever 1. In this embodiment, there are two cooling gas outlets 13, which are respectively located at the top and bottom of the horizontal cantilever 1. In this embodiment, the cooling gas introduced into the cooling chamber is nitrogen, but it is not limited to this.

[0044] According to one embodiment of the present invention, such as Figure 1 As shown, at one end of the compensation mechanism 3, the inner box 32 and the outer box 31 are sealed together by a non-metallic structure 33, which is made of an airtight material and / or a stretchable sealing material.

[0045] The non-metallic structure 33 enables a sealed connection between the inner casing 32 and the outer casing 31, preventing the cooling medium in the cooling chamber 11 from being discharged outward through the annulus between the outer casing 31 and the inner casing 32. At the same time, the non-metallic structure 33 is made of airtight material and / or stretchable sealing material, which can maintain the sealed state between the inner casing 32 and the outer casing 31 when the inner casing 33 and the outer casing 31 are misaligned due to heat and undergo thermal displacement, thus preventing the leakage of cooling gas.

[0046] In one embodiment of the invention, the non-metallic structure 33 includes a first sealing ring 331 and a second sealing ring 332. The first sealing ring 331 is sealed and connected in the annular space between the outer housing 31 and the inner housing 32. The second sealing ring 332 is sealed and connected to the end of the outer housing 31 and is connected to the first sealing ring 331. The first sealing ring 331 is made of a stretchable sealing material, and the second sealing ring 332 is made of an airtight material. Specifically, in this embodiment, the stretchable sealing material can be silicone, which is generally rope-shaped and is wrapped around the annular space between the outer housing 31 and the inner housing 32. The airtight material can be silicone fluororubber, but is not limited thereto.

[0047] The compensation dust removal rapping device of the present invention is installed on the particle collection device 4. The particle collection device 4 has an outer shell 41, wherein one end of the horizontal cantilever 1 connected to the vibration transmission member 2 extends into the outer shell 41, the end of the inner box 32 that extends out of the outer box 31 is connected to the outer shell 41 and can extend into the outer shell 41, and the outer box 31 is located on the outside of the outer shell 41.

[0048] In this embodiment, the cooling gas inlet 12 is located at the end of the horizontal cantilever 1 outside the particle collection device 4. The cooling gas inlet 12 is connected to the cooling chamber 11 and is located in the middle of the end of the horizontal cantilever 1. Of course, in other embodiments, the cooling gas inlet 12 can also be located at the bottom of the end of the horizontal cantilever 1, which is not limited here.

[0049] The outlet of the cooling channel 321 between the inner box 32 and the horizontal cantilever 1 is located inside the outer box 41, that is, the cooling channel 321 is connected to the inside of the particle collection device 4.

[0050] like Figure 2 As shown, in this invention, the vibration source is a vibration motor 5, which is connected to the other end of the horizontal cantilever 1 via a mounting plate 51.

[0051] The vibration motor 5 used in this invention can drive the horizontal cantilever 1 to vibrate synchronously by relying on the polarization force generated by its own rotation. The excitation frequency of the vibration motor 5 is the rapping frequency. Through the vibration during the rapping time, a vibration force is generated on the rapping point, thereby removing the accumulated dust on the equipment wall near the rapping point and achieving the purpose of dust removal. Compared with the traditional rapping method, the vibration frequency of the vibration motor 5 is higher and the damage to the point of action is less, which can better achieve the dust removal of the equipment and improve the service life of the equipment.

[0052] Specifically, the vibration motor 5 uses an adjustable eccentric block installed at each end of its rotor shaft to achieve reciprocating vibration. The vibration motor 5 is horizontally connected to the other end of the horizontal cantilever 1 via a mounting plate 51, for example, by bolts, but not limited thereto. The end of the horizontal cantilever 1 connected to the vibration transmission element 2 is fixedly connected to the impact point via the vibration transmission element 2. The entire installation of the compensation dust removal vibration device is completed, forming a cantilever structure. In this embodiment, under vibration, the vibration motor 5 generates polarization force by rotating itself. The polarization force is transmitted to the horizontal cantilever 1 via the mounting plate 51, causing the free end of the horizontal cantilever 1 to vibrate back and forth in the longitudinal direction of space, so that the polarization force is transmitted to the impact point via the vibration transmission element 2.

[0053] like Figure 1 As shown, according to one embodiment of the present invention, the cooling cavity 11 is provided with a plurality of cooling baffles 14, and the cooling cavity 11 is divided into a plurality of cooling channels 15 extending along the length direction F of the horizontal cantilever 1 by the plurality of cooling baffles 14.

[0054] The compensating dust removal rapping device of the present invention, through multiple cooling channels 15 formed by multiple cooling baffles 14 in the cooling chamber 11, enables the cooling gas to enter from the cooling gas inlet 12 and flow orderly along the multiple cooling channels 15, effectively absorbing the heat transferred from the surface of the horizontal cantilever 1 due to heating, and dissipating the heat more efficiently, avoiding thermal deformation of the horizontal cantilever 1 due to high temperature, and solving the problem of equipment aging and failure caused by continuous high temperature operation of existing compensating dust removal rapping devices.

[0055] Specifically, multiple cooling baffles 14 are arranged alternately from top to bottom within the horizontal cantilever 1 along the length direction F of the horizontal cantilever 1; of course, in other embodiments, multiple cooling baffles 14 can also be arranged alternately at intervals perpendicular to the length direction F of the horizontal cantilever 1, and the arrangement method is not limited to this.

[0056] The cooling baffle 14 is generally rectangular in shape, and the cooling channel 15 is formed between two adjacent cooling baffles 14. In this invention, at least one short side and two long sides of the cooling baffle 14 are connected to the inner wall of the horizontal cantilever 1. The other short side of the cooling baffle 14 is a free side 141, which is spaced apart from the inner wall of the cooling cavity 11. The two adjacent cooling baffles 14 are spaced apart. When viewed from above, the two adjacent cooling baffles 14 partially overlap, that is, the free sides 141 of two adjacent cooling baffles 14 overlap each other.

[0057] In one feasible embodiment of the present invention, such as Figure 1 As shown, the compensation cleaning rapping device is installed on the particle collection device 4, which has an outer shell 41 and a water-cooling pipe 42 located inside the outer shell 41.

[0058] In this embodiment, the particle collection device 4 is a sleeve-shaped particle collection device based on inclined plate settling technology. The device includes a spark collection device, an inner sleeve, and an outer sleeve. The flue gas enters the spark collection device from the inner sleeve and flows out from the outer sleeve (the structure of the sleeve-shaped particle collection device 4 is not shown in the attached figure). The water-cooling pipe 42 is inserted into the spark collection device. In this embodiment, the vibration transmission component 2 of the compensation cleaning rapping device is a sleeve 21. The sleeve 21 is detachably sleeved on the water-cooling pipe 42. One end of the horizontal cantilever 1 connected to the sleeve 21 extends into the outer shell 41, and the other end of the horizontal cantilever 1 connected to the sleeve 21 is fixedly connected to the outside of the sleeve 21.

[0059] In another feasible embodiment of the invention, such as Figure 3 As shown, the compensation cleaning rapping device is installed on the particle collection device 4, which has an outer shell 41 and an inner ash hopper 43 located inside the outer shell 41.

[0060] The particle collection device 4 in this embodiment is a sleeve-shaped particle collection device 4 based on inclined plate settling technology. The device includes a spark collection device, an inner sleeve 21 and an outer sleeve 21. The flue gas enters the spark collection device from the inner sleeve 21 and flows out from the outer sleeve 21 (the structure of the sleeve-shaped particle collection device 4 is not shown in the attached figure). The inner ash hopper 43 is located at the bottom of the spark collection device and is used to collect spark particles. The vibration transmission component 2 of the compensation ash cleaning rapping device in this embodiment is a pad 22. The pad 22 is generally arc-shaped and matches the shape of the outer wall of the inner ash hopper 43. The pad 22 abuts against the outer wall of the inner ash hopper 43. One end of the horizontal cantilever 1 connected to the pad 22 extends into the outer shell 41, and one end of the horizontal cantilever 1 connected to the sleeve 21 is fixedly connected to the pad 22.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
