Description

Technical Field

[0001] The present invention relates to the technical field of soot treatment, and in particular to a dust removal device for coke dry quenching and an exhaust gas treatment system. Background Art

[0002] Coke dry quenching is a coke cooling technology applied in the coking industry. This technology uses an inert gas as the cooling medium to replace the traditional water quenching method for cooling hot coke.

[0003] During the production process of coke dry quenching, after the red coke is pushed out of the coke oven carbonization chamber, it is loaded into the coke pot car and then sent to the coke dry quenching device for cooling. However, during the transportation of coke by the coke pot car to the storage or use location, especially in the device using an open coke pot car for transportation, the soot generated by the coke during transportation is directly discharged into the atmosphere, causing environmental pollution, and these soot also seriously threaten the physical health of the staff.

[0004] Refer to Figure 11 , in order to solve the problem of soot pollution during the transportation of the coke pot car, a frameless steel roof is usually set on the transportation path of the coke pot car to collect the flue gas and reduce the escape of soot.

[0005] However, since there is no support truss beam at the bottom of the steel roof, soot accumulates on the top of the steel roof. Due to the weight and thermal buoyancy effect of the soot, it is difficult to treat these soot with conventional dust removal equipment.

[0006] In view of the above related technologies, there is an urgent need for an improved technology for a dust removal device for coke dry quenching and an exhaust gas treatment system to effectively solve the problems of collection and treatment of soot on the top of the steel roof during the transportation of an open coke pot. Summary of the Invention

[0007] In view of this, the present invention provides a dust removal device for coke dry quenching and an exhaust gas treatment system, aiming to solve the technical problems of collection and treatment of soot on the top of the steel roof during the transportation of an open coke pot in the prior art.

[0008] In a first aspect, the present invention provides a dust removal device for coke dry quenching, including a plurality of collecting plates and a plurality of first suction pipes arranged along the long side direction of the steel roof; the collecting plates are arranged in an arched shape, and a channel for the flue gas to pass through is left between adjacent two collecting plates. The plurality of first suction pipes correspond to the plurality of collecting plates one by one, and the first suction pipes are arranged above the collecting plates; both sides in the long side direction of the steel roof are provided with suction pipelines, and both ends of the first suction pipes are sequentially communicated with the two suction pipelines; a suction groove extending along the axial direction of the first suction pipe is opened on the circumferential side wall of the first suction pipe, and the suction groove faces the arc-shaped inner wall of the top of the steel roof. A rotating member for controlling the first suction pipe to rotate around its own axis is arranged inside the steel roof.

[0009] By adopting the above technical solution, a collecting plate is provided, which can effectively guide the flow direction of the smoke, making it easier to collect the soot when it passes through the channel between two adjacent collecting plates. The first suction pipe corresponds to the collecting plate one by one, ensuring that the soot can be timely sucked when passing through the channel between two adjacent collecting plates, thereby improving the dust removal efficiency. The design of the suction groove enables the first suction pipe to more effectively suck the soot at the top of the steel roof, reducing the accumulation of soot at the top of the steel roof.

[0010] Moreover, the first suction pipe can rotate. By changing the direction of the first suction pipe, the opening or closing of the suction groove can be controlled. For areas with less soot, the suction groove can be closed. For areas with more soot, more suction grooves can be centrally opened to improve the suction efficiency in that area. When the suction volume of the suction pipeline is fixed, closing some of the first suction pipes can make the suction effect of the opened first suction pipes stronger and the suction effect better.

[0011] Optionally, the bottom of the joint surface between the collecting plate and the first suction pipe is set as a rounded corner, and a screw conveyor blade is fixedly connected to the inner wall of the first suction pipe.

[0012] By adopting the above technical solution, setting the bottom as a rounded corner can reduce the accumulation of soot on the top surface of the collecting plate. The rounded corner is not easy to form a dead angle, making it easier to collect and clean the soot on the top surface of the collecting plate. The design of the rounded corner can also reduce the mutual wear between the collecting plate and the first suction pipe, extending the service life of the device; as the first suction pipe rotates, the screw conveyor blade rotates and can push the soot on the first suction pipe and the collecting plate downward.

[0013] Optionally, the collecting plate is composed of a first plate arranged horizontally, two symmetrically arranged second plates, and two vertically arranged third plates. The two second plates are sequentially connected to both ends of the first plate. The two third plates correspond to the two second plates one by one and the third plates are connected to the bottom ends of the second plates. The top ends of the third plates are located below the first plate. The first suction pipe is composed of three first pipelines and two second pipelines. The three first pipelines are sequentially placed above the first plate and the two second plates. The two second pipelines are sequentially rotatably connected to the two third plates. The circumferential side wall of the first pipeline is provided with a suction groove. The adjacent second pipeline and the first pipeline are connected by a universal joint. The adjacent two first pipelines are connected by a universal joint; the lower end of the second pipeline is rotatably connected with a connecting pipe, and the connecting pipe is communicated with the suction pipeline.

[0014] By adopting the above technical solution, Plate One, Plate Two and Plate Three form a collecting plate, forming a stable frame structure that can withstand large loads and vibrations, ensuring the stability of the long-term operation of the device; an air extraction groove is opened on Pipeline One to centrally suck the soot accumulated in the arc area at the top of the steel roof. Pipeline Two is vertically placed to facilitate the transportation and collection and treatment of the sucked soot by Pipeline Two; a universal joint is used as a connecting piece. When one of Pipeline One or Pipeline Two rotates, it can drive the other Pipeline One and Pipeline Two to rotate, facilitating the control of the rotation of the air extraction pipe one to control the orientation and switch of the air extraction groove, and the universal joint can adapt to the displacement of the pipeline, reducing stress concentration and extending the service life of the pipeline.

[0015] Optionally, the rotating member includes a moving rod slidably connected to the steel roof along the long side direction of the steel roof. A plurality of connecting teeth arranged along the long side direction are fixedly connected to the side wall of the moving rod. A gear one is fixedly sleeved on the circumferential side wall of one of the Pipeline Twos, and the gear one meshes with the connecting teeth; a support rod is assembled on the top of the steel roof, the moving rod is slidably connected to the support rod, a driving motor is connected to the moving rod, and an output end of the driving motor is fixedly connected to a driving wheel. A through groove for the driving wheel to move is opened on the support rod.

[0016] By adopting the above technical solution, through the movement of the moving rod, the connecting teeth are sequentially engaged with the gear one. When the connecting teeth pass through the gear one, the gear one is driven to rotate a certain angle, facilitating the adjustment of the orientation and switch of the air extraction groove. The setting of the driving motor and the driving wheel facilitates the control of the reciprocating movement of the moving rod along the long side direction of the steel roof.

[0017] Optionally, the lengths of the plurality of connecting teeth on the moving rod are greater than the diameter of the coke pot on the coke pot car. In the long side direction of the steel roof, when the midpoint of the moving rod corresponds to the midpoint of the coke pot car, the air extraction groove of the air extraction pipe one corresponding to the midpoint of the moving rod faces directly upward, and the air extraction groove of the air extraction pipe one corresponding to the edge of the coke pot car is inclined. And during the process of the moving rod coming into contact with and separating from the gear one, the gear one rotates 360 degrees.

[0018] By adopting the above technical solution, the air extraction groove located above the midpoint of the coke pot car is vertically opened upward, with the widest air extraction range. The air extraction groove located at the edge of the coke pot car is inclined, facilitating the suction of the soot at the passage, improving the suction efficiency and suction effect; the gear one rotates 360 degrees, causing the air extraction groove to gradually open and then gradually close, so that the air extraction volume of the air extraction pipeline can be concentrated on some of the air extraction pipes, enhancing the suction effect.

[0019] Optionally, the bottom surface of the collecting plate is composed of two inclined planes, and the bottoms of the two inclined planes are connected.

[0020] By adopting the above technical solution, it has a guiding effect on the flue gas, reducing the accumulation of soot at the bottom of the collecting plate.

[0021] Optionally, exhaust pipes II are provided at both ports of the steel roof.

[0022] By adopting the above technical solution, when the coke pot car has not entered the steel roof or has just entered below the steel roof, the exhaust pipe II assists in suction, improving the suction effect and reducing environmental pollution.

[0023] Optionally, a control member for controlling the rotation of the exhaust pipe II is provided on the steel roof, and the control member can make the air extraction port on the exhaust pipe II face the coke pot car.

[0024] By adopting the above technical solution, the air extraction port faces the coke pot car, improving the suction effect of the exhaust pipe II on the soot.

[0025] Optionally, the control member includes a rack connected to the coke pot car. The bottom of the steel roof is rotatably connected to a gear II through a hinge shaft. The gear II meshes with the rack. The exhaust pipe II is rotatably connected to the steel roof through a hinge shaft. A belt transmission member is used to link the hinge shaft of the exhaust pipe II and the hinge shaft of the gear II.

[0026] By adopting the above technical solution, when the coke pot car passes by, it drives the exhaust pipe II to rotate so that the air extraction port faces the coke pot car, which is convenient to use and improves the automation degree of the device.

[0027] In the second aspect, an exhaust gas treatment system for dry quenching of coke provided by the present invention uses a dust removal device for dry quenching of coke proposed in the first aspect to collect and treat the soot on the top of the steel roof.

[0028] In summary, the present invention has the following beneficial technical effects:

[0029] 1. The collection plates are provided, which can effectively guide the flow direction of the smoke, making it easier to collect the soot when passing through the channels between adjacent two collection plates. The exhaust pipe I corresponds to the collection plate one by one, ensuring that the soot can be timely sucked when passing through the channels between adjacent two collection plates, thereby improving the dust removal efficiency. The design of the air extraction groove enables the exhaust pipe I to more effectively suck the soot on the top of the steel roof, reducing the accumulation of soot on the top of the steel roof;

[0030] The exhaust pipe I can rotate. By changing the direction of the exhaust pipe I, the opening or closing of the air extraction groove can be controlled. For areas with less soot, the air extraction groove can be closed. For areas with more soot, more air extraction grooves can be centrally opened to improve the air extraction efficiency in this area. When the air extraction volume of the air extraction pipeline is fixed, closing some of the exhaust pipes I can make the air extraction effect of the opened exhaust pipes I stronger and the suction effect better.

[0031] 2. The bottom is rounded, which can reduce the accumulation of soot on the top surface of the collection plate, making it easier to collect and clean the soot on the top surface of the collection plate. The rounded design can also reduce the mutual wear between the collection plate and the first extraction pipe, extending the service life of the device.

[0032] 3. As the first extraction pipe rotates, the auger blades rotate and can push the soot on the first extraction pipe and the collection plate downward.

[0033] 4. Extraction slots are opened on the first pipeline to centrally suck the soot accumulated in the arc area at the top of the steel roof. The second pipeline is vertically placed to facilitate the transportation and collection of the sucked soot; A universal joint is used as a connecting piece. When one of the first pipelines or the second pipeline rotates, it can drive the other first pipelines and the second pipeline to rotate, facilitating the control of the rotation of the first extraction pipe to control the orientation and switch of the extraction slots. Moreover, the universal joint can adapt to the displacement of the pipeline, reduce stress concentration, and extend the service life of the pipeline.

[0034] 5. The lengths of the multiple connecting teeth on the moving rod are greater than the diameter of the coke pot on the coke pot car, so that the extraction slot above the midpoint of the coke pot car is vertically upward and wide open, with the widest extraction range. The extraction slot at the edge of the coke pot car is inclined to facilitate the extraction of the soot at the passage, improving the extraction efficiency and effect; The first gear rotates 360 degrees, causing the extraction slot to gradually open and then gradually close, so that the extraction volume of the extraction pipeline can be concentrated on some of the extraction pipes, enhancing the extraction effect.

[0035] 6. The second extraction pipe assists in extraction, enhancing the extraction effect and reducing environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the protection scope of the present invention.

[0049] The following will Figure 1 - be Figure 10 further described in detail with reference to the attached

[0050] In a first aspect, an embodiment of the present invention discloses a dust removal device for dry quenching of coke.

[0051] Referring to Figures 1 to 10 , a dust removal device for dry quenching of coke includes a collection plate 1, a first extraction pipe 2, a rotating part 3, a second extraction pipe 4 and a control part 5.

[0052] Referring to Figure 1 , Figure 2 and Figure 3, there are multiple collection plates 1. The multiple collection plates 1 are arranged along the long side direction of the steel roof 10. The collection plates 1 are connected to the steel roof 10 and are provided at the arc-shaped inner wall at the top of the steel roof 10. The collection plates 1 are arched, and a passage 6 for flue gas to pass through is left between two adjacent collection plates 1. Among them, for the clarity of the illustration, Figure 2 part of the first extraction pipe 2 is hidden in Figure 3 and the end collection plate 1 is hidden in

[0053] Setting the collection plates 1 can effectively guide the flow direction of the flue gas, making it easier to collect the soot when it passes through the passage 6 between two adjacent collection plates 1.

[0054] Refer to Figure 2 and Figure 3 , there are multiple first extraction pipes 2. The multiple first extraction pipes 2 are arranged along the long side direction of the steel roof 10. The multiple first extraction pipes 2 correspond to the multiple collection plates 1 one by one, and the first extraction pipes 2 are placed above the collection plates 1. Refer to Figure 8 and Figure 9 , an extraction groove 211 extending along its own axial direction is opened on the circumferential side wall of the first extraction pipe 2, and the extraction groove 211 faces the arc-shaped inner wall at the top of the steel roof 10.

[0055] The first extraction pipes 2 correspond to the collection plates 1 one by one, ensuring that the soot can be timely sucked when it passes through the passage 6 between two adjacent collection plates 1, thereby improving the dust removal efficiency. The design of the extraction groove 211 enables the first extraction pipes 2 to more effectively suck the soot at the top of the steel roof 10 and reduce the accumulation of soot at the top of the steel roof 10.

[0056] Refer to Figure 4 , Figure 5 and Figure 8 , a rotating member 3 is provided inside the steel roof 10, and the rotating member 3 is used to control the rotation of the first extraction pipe 2 around its own axis.

[0057] By changing the direction of the first extraction pipe 2, the opening or closing of the extraction groove 211 can be controlled. For areas with less soot, the extraction groove 211 can be closed. For areas with more soot, more extraction grooves 211 can be centrally opened to improve the extraction efficiency in this area. When the extraction volume of the extraction pipeline 7 is fixed, closing some of the first extraction pipes 2 can make the extraction effect of the opened first extraction pipes 2 stronger and the suction effect better.

[0058] Refer to Figure 3 , extraction pipelines 7 are connected to both sides of the steel roof 10 in the long side direction, and both ends of the first extraction pipe 2 are sequentially communicated with the two extraction pipelines 7.

[0059] Two air extraction pipes 7 extract air, and then the first air extraction pipe 2 extracts air. The arrangement of the air extraction pipes 7 facilitates the control of the air extraction of multiple first air extraction pipes 2, facilitates the rational layout of the pipeline, facilitates the maintenance of the device, and reduces the situation of mutual conflict between structures.

[0060] Refer to Figure 6 、 Figure 8 and Figure 9 Furthermore, the bottom of the joint surface between the collection plate 1 and the first air extraction pipe 2 is rounded, and auger blades 8 are fixedly connected to the inner walls of both the first pipeline 21 and the second pipeline 22.

[0061] Setting the bottom as a rounded corner can reduce the accumulation of soot on the top surface of the collection plate 1. The rounded corner is not easy to form a dead angle, making it easier to collect and clean the soot on the top surface of the collection plate 1. The design of the rounded corner can also reduce the mutual wear between the collection plate 1 and the first air extraction pipe 2, extending the service life of the device; as the first air extraction pipe 2 rotates, the auger blade 8 rotates and can push the soot on the first air extraction pipe 2 and the collection plate 1 to move downward.

[0062] Refer to Figure 6 and Figure 7 Furthermore, the collection plate 1 is composed of a first plate 11, two second plates 12, and two third plates 13. The first plate 11 is horizontally arranged, the two second plates 12 are symmetrically arranged at both ends of the first plate 11, the top end of the second plate 12 is connected to the end of the first plate 11, the second plate 12 is inclined downward and away from the first plate 11 from top to bottom, the third plates 13 are vertically arranged, the two third plates 13 correspond to the two second plates 12 one by one, and the top end of the third plate 13 is connected to the bottom end of the second plate 12.

[0063] The first plate 11, the second plates 12, and the third plates 13 form the collection plate 1, forming a stable frame structure that can bear large loads and vibrations, ensuring the stability of the long-term operation of the device.

[0064] Refer to Figure 8 and Figure 9 The first air extraction pipe 2 is composed of three first pipelines 21 and two second pipelines 22. One first pipeline 21 is placed on both the first plate 11 and the two second plates 12. The two second pipelines 22 correspond to the two third plates 13 one by one. The circumferential side wall of the second pipeline 22 is rotatably connected to the third plate 13. The circumferential side wall of the first pipeline 21 is provided with an air extraction groove 211, and the air extraction groove 211 faces the arc-shaped inner wall at the top of the steel roof 10.

[0065] Refer to Figure 8 An air extraction groove 211 is opened on the first pipeline 21 to centrally suck the soot accumulated in the arc-shaped area at the top of the steel roof 10. The second pipeline 22 is vertically placed, facilitating the transportation and collection and treatment of the sucked soot by the second pipeline 22.

[0066] Refer to Figure 8 andFigure 9 The adjacent pipeline 2 22 is connected to the pipeline 1 21 through a universal joint, and the adjacent two pipelines 1 21 are connected through a universal joint.

[0067] By using a universal joint as a connecting piece, when one of the pipelines 1 21 or pipeline 2 22 rotates, it can drive the other pipelines 1 21 and pipeline 2 22 to rotate, so as to facilitate the control of the rotation of the exhaust pipe 1 2 to control the direction and switch of the exhaust groove 211, and the universal joint can adapt to the displacement of the pipeline, reduce stress concentration, and extend the service life of the pipeline.

[0068] Reference Figure 4 The lower end of the pipeline 22 is rotatably connected with a connecting pipe 9, and the connecting pipe 9 is communicated with the air extraction pipeline 7. To ensure the normal operation of the device, conflicts between structures are avoided as much as possible.

[0069] Reference Figure 4 and Figure 5 Specifically, the rotating member 3 includes a moving rod 31, a connecting tooth 32, a gear 33, a supporting rod 34, a driving motor 35 and a driving wheel 36.

[0070] The moving rod 31 is slidably connected to the steel roof 10 along the long side direction of the steel roof 10, a plurality of connecting teeth 32 are provided, and the connecting teeth 32 are fixedly connected to the side wall of the moving rod 31. The plurality of connecting teeth 32 are evenly arranged along the long side direction of the steel roof 10, and the gear 1 33 is fixedly connected to the circumferential side wall of one of the pipelines 22, and the gear 1 33 is meshed with the connecting teeth 32.

[0071] By moving the moving rod 31 , the connecting teeth 32 mesh with the gear 1 33 in sequence. When the connecting teeth 32 pass through the gear 1 33 , the gear 1 33 is driven to rotate a certain angle, so as to adjust the direction of the air extraction slot 211 and the switch of the air extraction slot 211 .

[0072] The support rod 34 is placed horizontally and assembled on the top of the steel roof 10, the moving rod 31 is slidably connected to the support rod 34, the driving motor 35 is fixedly connected to the moving rod 31, the driving wheel 36 is fixedly sleeved on the output end of the driving motor 35, and a through groove is opened on the support rod 34 for the driving wheel 36 to move.

[0073] The driving motor 35 is started to drive the driving wheel 36 to rotate, thereby driving the movement of the moving rod 31. Furthermore, in other embodiments, a rack 51 may be provided on the support rod 34, and a gear may be provided at the output end of the driving motor 35, and the gear meshes with the rack 51, thereby driving the movement of the moving rod 31.

[0074] Reference Figure 1 , Figure 3 and Figure 5, Further, the lengths of the multiple connecting teeth 32 on the moving rod 31 are greater than the diameter of the coke pot on the coke pot car. In the long side direction of the steel roof 10, when the midpoint of the moving rod 31 corresponds to the midpoint of the coke pot car, the air extraction slot 211 of the first air extraction pipe 2 corresponding to the midpoint of the moving rod 31 faces directly upward, and the air extraction slot 211 of the first air extraction pipe 2 corresponding to the edge of the coke pot car is inclined. Moreover, during the process of the moving rod 31 coming into contact with and then separating from the first gear 33, the first gear 33 rotates 360 degrees.

[0075] This makes the air extraction slot 211 above the midpoint of the coke pot car open vertically upward, with the widest air extraction range. The air extraction slot 211 at the edge of the coke pot car is inclined, facilitating the suction of the soot at the passage 6 and improving the suction efficiency and effect. The first gear 33 rotates 360 degrees, causing the air extraction slot 211 to gradually open and then gradually close, enabling the air extraction volume of the air extraction pipe 7 to be concentrated on some of the air extraction pipes and enhancing the suction effect.

[0076] Refer to Figure 6 , Further, the bottom surface of the collecting plate 1 is composed of two inclined surfaces, and the bottoms of the two inclined surfaces are connected.

[0077] It has a guiding effect on the flue gas, reducing the accumulation of soot at the bottom of the collecting plate 1.

[0078] Refer to Figure 3 , There are two second air extraction pipes 4, and the two second air extraction pipes 4 are sequentially arranged at the two ports of the steel roof 10.

[0079] Refer to Figure 1 and Figure 3 , The control member 5 is used to control the rotation of the second air extraction pipe 4 so that the air extraction port 41 on the second air extraction pipe 4 faces the coke pot car.

[0080] When the coke pot car has not entered the steel roof 10 or has just entered below the steel roof 10, the second air extraction pipe 4 assists in suction, enhancing the suction effect and reducing environmental pollution. The air extraction port 41 faces the coke pot car, improving the suction effect of the second air extraction pipe 4 on the soot.

[0081] Refer to Figure 1 and Figure 3 , Specifically, the control member 5 includes a rack 51, a second gear 52, and a belt transmission member.

[0082] The rack 51 is fixedly connected to the coke pot car. The second gear 52 is rotatably connected to the bottom of the steel roof 10 through a hinge shaft. The second gear 52 meshes with the rack 51. The second air extraction pipe 4 is rotatably connected to the steel roof 10 through a hinge shaft, and the belt transmission member is arranged between the hinge shaft of the second air extraction pipe 4 and the hinge shaft of the second gear 52.

[0083] When the coke pot car passes by, the rack 51 drives the gear to rotate. Through the belt conveyor, the second suction pipe 4 rotates, so that the suction port 41 faces the coke pot car, which is convenient for use and improves the automation degree of the lifting device.

[0084] The implementation principle of a dust removal device for dry coke quenching according to an embodiment of the present invention is as follows:

[0085] During the process of the coke pot car gradually entering the inlet of the steel roof 10, the rack 51 on the coke pot car meshes with the second gear 52, driving the second gear 52 to rotate. Through the belt conveyor, the second suction pipe 4 is driven to rotate, so that the suction port 41 of the second suction pipe 4 faces the coke pot car.

[0086] When the coke pot car enters below the steel roof 10, the output end of the drive motor 35 rotates, driving the moving rod 31 to move along the long side direction of the steel roof 10. A plurality of connecting teeth 32 are successively meshed with a plurality of first gears 33, driving the first suction pipe 2 to rotate, and the suction slots 211 are opened. A plurality of suction slots 211 located above the coke pot car are all opened, and the area of the opened suction slots 211 is larger than the area of the coke pot car. According to the different numbers of the meshed connecting teeth 32, the rotation angle of the first gear 33 is different. The suction slot 211 located directly above the central axis of the coke pot car faces directly upward, and the suction slots 211 located at the edge of the coke pot car are inclined. The soot in the arc-shaped area at the top of the steel roof 10 and the soot at the passage 6 are collected.

[0087] During the process of the coke pot car leaving from the outlet of the steel roof 10, the second suction pipe 4 at the outlet of the steel roof 10 rotates, and the suction port 41 faces the coke pot car.

[0088] In a second aspect, an embodiment of the present invention discloses an exhaust gas treatment system for dry coke quenching:

[0089] A dust removal device for dry coke quenching proposed in the first aspect is used to collect and process the soot on the top of the steel roof 10.

[0090] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0091] The above is the preferred implementation mode of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
