Description

Technical Field

[0001] The present invention belongs to the technical field of graphite preprocessing, and particularly relates to a pretreatment device for special graphite carbon materials. Background Art

[0002] Graphite carbon materials have the advantages of high density, high purity, oxidation resistance, strong electrical conductivity, good thermal shock resistance and long service life, and are often used as refractory materials and conductive materials. During the preparation process of graphite carbon materials, a large number of petroleum coke blocks need to be crushed. There are many pores inside and outside the petroleum coke blocks, which will absorb a large amount of moisture when stacked outdoors, and the blocks themselves will soften and adhere, resulting in sticking to the cutter during crushing and reducing the crushing effect.

[0003] Chinese Patent with the authorization announcement number CN110926158B discloses a drying device for petroleum coke processing, including a drying box. The lower surface of the drying box is fixedly connected with three support legs, and the three support legs form a triangular structure. The top of the drying box is fixedly connected with a top cover. The middle of the upper surface of the top cover is fixedly connected with a motor, and the motor longitudinally penetrates the top cover and is fixedly connected with a spiral rotating shaft. A through hole is opened in the middle of the bottom end of the drying box, and a support frame is fixedly connected inside the through hole. A rotating seat is fixedly connected to the support frame, and the rotating seat is fixedly connected to the bottom end of the spiral rotating shaft. One side of the drying box is fixedly connected with a blower, and above the blower on one side of the drying box is fixedly connected with a heating box. A box door is hinged on the heating box, and a sealing strip for sealing is fixedly connected to the box door. The air outlet pipe of the blower is fixedly connected to the bottom end of the heating box. The present invention improves the drying efficiency, reduces the drying time, has uniform heating, simple structure, convenient use, and does not affect subsequent operations.

[0004] In the prior art, through the spiral rotating shaft to stir and turn the petroleum coke and cooperate with the blower, the effects of reducing the drying time and uniform heating are achieved, but there are still certain problems: when the petroleum coke blocks adsorb moisture, they will adhere to each other, and more moisture will accumulate on the adhesion surface. It is difficult to completely separate them by simple stirring and turning, and the drying gas cannot penetrate deeply for drying. Therefore, the prior art cannot efficiently dry the adhered petroleum coke blocks.

[0005] Therefore, a pretreatment device for graphite carbon materials is designed to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to propose a pretreatment device for special graphite carbon materials aiming at the above problems existing in the prior art. Through the cooperation of the first bending rod and the second bending rod that rotate quickly and the arc-shaped block that bounces quickly, the present invention can quickly disperse the adhered petroleum coke blocks and drive them to swing at the same time. During the process of falling and rolling downward after being dispersed, the high-temperature gas ejected through the second air pipe and the second air jet port can effectively remove the moisture inside the petroleum coke blocks, greatly improving the crushing and grinding effect.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A special graphite carbon material pretreatment device, including a fixed base and a support main board. Four pairwise symmetric support main boards are fixedly arranged at the four corners of the upper end surface of the fixed base. Between the pairwise arranged support main boards, a bearing seat is connected. Between the two bearing seats, a preparation cylinder is rotatably arranged above the fixed base. The upper end surface of the preparation cylinder is communicated with a vibration cone cylinder with conical surfaces on both the upper and lower sides. The upper end surface of the vibration cone cylinder is communicated with a feed pipe orifice. Below the feed pipe orifice, a fixed bottom plate is fixedly arranged at the center of the vibration cone cylinder. Above the fixed bottom plate, a throwing component is rotatably arranged. The throwing component includes a rotating disk rotatably arranged above the fixed bottom plate. Along the circumferential direction on the upper end surface of the rotating disk, a plurality of second bending rods bent inwards are evenly arranged. On the outer inclined surfaces of the plurality of second bending rods far from the center of the rotating disk, a plurality of second elastic blocks are evenly arranged along the straight line direction. The rotating second bending rods and the second elastic blocks can throw the falling solid objects to the upper inner conical surface of the vibration cone cylinder. Below the second bending rods, an umbrella cover drying component is arranged on the outer circular surface of the fixed bottom plate. The umbrella cover drying component includes a plurality of first ventilation pipes evenly connected along the circumferential direction on the outer circular surface of the fixed bottom plate. Between the plurality of first ventilation pipes, an elastic net with good air permeability is connected. Between the bottom outer circular surface of the elastic net and the inner wall of the preparation cylinder, a material dropping port is arranged. Below the material dropping port, a grinding component is arranged in the preparation cylinder. The grinding component includes a grinding conical wall fixedly arranged on the inner wall of the preparation cylinder below the material dropping port and inclined downwards in a converging manner. At the center of the grinding conical wall, a grinding conical block is rotatably arranged and is matched with the grinding conical wall. Below the grinding conical block, a sliding opening is arranged at the bottom of the preparation cylinder. In the sliding opening, a material dropping disk for collecting powder is slidably arranged. The second bending rods bent inwards can use the plurality of second elastic blocks on their bending surfaces to throw and disperse the agglomerated petroleum coke blocks when the petroleum coke blocks fall downwards. The elastic net can improve the fluidity of hot air and at the same time slow down the rolling speed of the petroleum coke blocks, so that the drying can be effectively carried out.

[0008] Preferably, on both sides of the preparation cylinder, rotating main shafts are rotatably arranged at the center of the end surface of the bearing seat. The ends of the rotating main shafts close to the preparation cylinder are respectively connected to the outer circular surface of the preparation cylinder. On the outer circular surface of one of the rotating main shafts between the bearing seat and the preparation cylinder, a first tooth ring is arranged. On one side of the first tooth ring, a first gear is rotatably arranged. The first gear and the first tooth ring are in meshing transmission. On one side of the first gear, a first driving motor is fixedly arranged on the end surface of the bearing seat. The output end of the first driving motor is connected to the center of the end surface of the first gear. The setting of the first driving motor and the first gear enables the preparation cylinder to turn over, so that the rolling of the internal petroleum coke blocks can be more smooth.

[0009] Preferably, a rebound crushing assembly is provided on the inner conical surface at the upper end of the vibration cone. The rebound crushing assembly includes a plurality of vibration bases uniformly arranged along the circumferential direction on the inner conical surface at the upper end of the vibration cone. A linkage elastic plate is slidably arranged in each vibration base. A plurality of elastic rods are uniformly arranged along the linear direction at one end of the linkage elastic plate close to the center of the vibration cone. One end of each elastic rod away from the linkage elastic plate extends out of the end face of the vibration base. An arc-shaped block is connected to the end of the elastic rod extending out of the end face of the vibration base. One end of a plurality of first springs is connected to the end face of the linkage elastic plate away from the elastic rods, and the other ends of the plurality of first springs are connected to the bottom end face of the vibration base. The plurality of arc-shaped blocks surround each other to form a conical surface. The petroleum coke blocks thrown outwards by the second bent throwing rod will contact the arc-shaped blocks, and the arc-shaped blocks will not only vibrate rapidly under the action of the first springs but also disperse the petroleum coke blocks.

[0010] Preferably, a plurality of crushing tooth surfaces for crushing are uniformly arranged along the circumferential direction on the wall surface of the arc-shaped block close to the center of the preparation cylinder. A plurality of rubber elastic balls made of rubber are uniformly arranged along the circumferential direction on the inner wall of the arc-shaped block between the plurality of crushing tooth surfaces. A second driving motor is fixedly arranged on the top end face of the fixed bottom plate below the rubber elastic ball. The output end of the second driving motor is connected to the bottom end face of the rotating disk. If the petroleum coke block contacts the rubber elastic ball, the bouncing speed will be increased, so that the internal moisture can be thrown out. If it contacts the crushing tooth surface, it will break by itself, thus avoiding the situation of particle adhesion.

[0011] Preferably, a fixed net plate is fixedly arranged in the preparation cylinder below the fixed bottom plate. A second air seat is fixedly arranged on the end face of the fixed net plate. A rotating air shaft with a hollow interior is rotatably arranged at the center of the bottom end face of the second air seat. One end of the rotating air shaft away from the vibration cone extends into the grinding cone wall. A grinding cone block is connected to the end of the rotating air shaft extending into the grinding cone wall. The outer circular surface at the upper end of the grinding cone block is inclined upwards in a conical shape. A funnel-shaped space is formed between the conical surface at the upper end of the grinding cone block and the grinding cone wall. A first grinding surface for grinding and crushing is arranged on the outer circular surface of the grinding cone block. A second grinding surface is arranged on the inner wall of the grinding cone wall outside the first grinding surface. A grinding gap exists between the first grinding surface and the second grinding surface. A second tooth ring is arranged on the outer circular surface of the rotating air shaft away from the grinding cone block. A second gear is rotatably arranged below the fixed net plate on one side of the second tooth ring. The outer circular surface of the second gear is in meshing transmission with the outer circular surface of the second tooth ring. A third driving motor is fixedly arranged on the end face of the fixed net plate above the second gear. The output end of the third driving motor is connected to the top end face of the second gear. The rotating air shaft can not only rotate the grinding cone block but also convey gas.

[0012] Preferably, a plurality of second ventilation pipes for heat-conducting ventilation are evenly connected and arranged on the outer circular surface of the first ventilation pipe near the feed pipe opening in the circumferential direction of the first ventilation pipe, and the plurality of second ventilation pipes are all arranged above the elastic net, and a heat-conducting patch is connected and arranged between the plurality of second ventilation pipes on the outer circular surface of the elastic net, and the plurality of second ventilation pipes are evenly connected and arranged with air jet seats in the circumferential direction on the outer circular surface, and a plurality of second air jet ports are evenly arranged on the outer circular surface of the plurality of air jet seats in the circumferential direction, and a second heating block is fixedly arranged in the first ventilation pipe below the second air jet ports, and a first air seat is fixedly arranged on the bottom end surface of the fixed bottom plate on one side of the first ventilation pipe, and a first heating block is fixedly arranged in the first air seat, and one end of a plurality of connecting hoses is connected and arranged on the outer circular surface of the first ventilation pipe, and the other end of the plurality of connecting hoses is connected and arranged on the outer circular surface of the first ventilation pipe, and the outer circular surface of one side of the first air seat is connected and arranged with a second air inlet pipe extending out of the outer circular surface of the preparation cylinder. While transmitting hot gas, the second ventilation pipe also conducts heat itself, causing the temperature of the connected elastic net to rise. The transmitted hot gas will enter the jet seat and then be ejected outward from the second jet port. When the petroleum coke blocks are rolled and dried on the surfaces of the elastic net and the second ventilation pipe with higher temperatures, the hot gas can be injected into the interior of the petroleum coke blocks by utilizing their good air permeability, thereby effectively improving the drying effect.

[0013] Preferably, an inclined bottom plate is fixedly mounted on the inner wall of the preparation cylinder between the plurality of first ventilation tubes. The inclined surface of the inclined bottom plate is in contact with the bottom of each elastic net. Multiple vibrators are evenly arranged along the circumference of the end surface of the inclined bottom plate in contact with the bottom of the elastic net. The vibrators increase the rolling speed of the petroleum coke blocks on the surface of the elastic net, preventing accumulation of the petroleum coke blocks.

[0014] Preferably, a plurality of stirring and ventilation rods are uniformly arranged on the outer circumferential surface of the rotating air shaft above the grinding cone block, the stirring and ventilation rods extending from one end of the rotating air shaft to the funnel opening formed by the grinding cone block and the grinding cone wall, a first air jet is connected to the bottom end surface of the stirring and ventilation rod extending into the funnel, a connecting plate is provided on one side of the first air jet on the end surface of the stirring and ventilation rod away from the rotating air shaft, one end of a rotating inner rod is connected to the bottom end surface of the connecting plate, the other end of the rotating inner rod extends into the funnel opening, a rotating outer cylinder is rotatably arranged on the outer circumferential surface of the rotating inner rod extending into the funnel opening, a plurality of undulating plates are uniformly arranged on the outer circumferential surface of the rotating outer cylinder, and a second air inlet pipe is connected to the outer circumferential surface of one side of the second air seat above the stirring and ventilation rod. The rotating outer cylinder and the undulating plates can move the accumulated petroleum coke blocks, and the high-pressure gas ejected from the first air jet can effectively prevent the petroleum coke blocks from clogging.

[0015] Preferably, a plurality of first bending rods that bend outward and spread out are uniformly connected in the circumferential direction between the upper end surfaces of the rotating disks. A plurality of first elastic blocks are uniformly arranged in a straight line direction on the inclined surfaces of the upper ends of the plurality of first bending rods close to the feed pipe orifice. A plurality of elastic ropes are uniformly connected in the contour line direction between the plurality of first bending rods. During the process of the first bending rods that bend outward and spread out cooperating with the elastic ropes to catch a large number of downward-falling petroleum coke blocks and swing them outward, the petroleum coke blocks will rotate multiple times, enabling the rapid expulsion of internal moisture and improving the drying effect.

[0016] Beneficial effects:

[0017] 1. Through the design of components such as the first bending and throwing rods, the second bending and throwing rods, the elastic ropes, and the arc-shaped blocks in the present invention, while a large number of downward-falling petroleum coke blocks are broken when they are swung outward by the second bending and throwing rods and hit the arc-shaped blocks, the first bending and throwing rods and the elastic ropes can also swing some of the petroleum coke blocks at high speed to expel the internal moisture, effectively improving the subsequent drying effect.

[0018] 2. Through the design of components such as the elastic net, the second ventilation pipe, the heat-conducting patch, and the air jet seat in the present invention, while a large number of scattered petroleum coke blocks can freely roll and dry slowly on the high-temperature elastic net and the heat-conducting patch, the air jet seat can also spray high-temperature gas into the interior of the petroleum coke blocks, greatly improving the drying efficiency and effectively avoiding the situation of sticking to the knife during crushing.

[0040] Further, as Figure 4 , Figure 5 , Figure 8 and Figure 11 shown, on the outer circumferential surface of the first air pipe 44 near the feed pipe opening 12, a plurality of second air pipes 55 for heat conduction and ventilation are uniformly connected in a circumferential direction along the inclined direction of the first air pipe 44. A plurality of second air pipes 55 are all arranged above the elastic net 43. A heat conduction patch 56 is connected to the outer circumferential surface of the elastic net 43 between a plurality of second air pipes 55. A plurality of air jet seats 66 are uniformly connected in a circumferential direction on the outer circumferential surfaces of a plurality of second air pipes 55. A plurality of second air jet openings 67 are uniformly arranged in a circumferential direction on the outer circumferential surfaces of a plurality of air jet seats 66.

One ends of a plurality of connecting hoses 54 are connected to the outer circumferential surface of the first air seat 30 in a communicating manner. The other ends of a plurality of connecting hoses 54 are connected to the outer circumferential surface of the first air pipe 44 in a communicating manner. A second air inlet pipe 21 extending out of the outer circumferential surface of the preparation cylinder 10 is connected to the outer circumferential surface of one side of the first air seat 30 in a communicating manner.

[0041] Further, as Figure 5 and Figure 7As shown, an inclined bottom plate 57 is fixedly arranged on the inner wall of the preparation cylinder 10 between multiple first ventilation pipes 44. The inclined surface of the inclined bottom plate 57 is attached to the bottom of each elastic net 43. A plurality of vibrators 58 for vibration are uniformly arranged along the circumferential direction on the end surface of the inclined bottom plate 57 attached to the bottom of the elastic net 43.

[0042] The device is powered on, and then the first driving motor 17 is started. The output end of the first driving motor 17 drives the first gear 18 to rotate, thereby driving the first toothed ring 19 meshing with it to rotate, thereby driving the rotating main shaft 16 arranged at the center of the first toothed ring 19 and the preparation cylinder 10 at one end of the rotating main shaft 16 to rotate, thereby driving the vibration cone 11 and the feed pipe orifice 12 arranged at the upper end of the preparation cylinder 10 to be straightened. At this time, the staff can pour the petroleum coke blocks into the vibration cone 11 through the feed pipe orifice 12.

[0043] Before the petroleum coke blocks are put into the vibration cone 11, the throwing assembly arranged on the end surface of the fixed bottom plate 26 is started first. The second driving motor 27 is powered on. The output end of the second driving motor 27 drives the rotating disk 28 to rotate, thereby driving a plurality of second bent rods 49 arranged on the end surface of the rotating disk 28 to rotate. During the rotation of the second bent rods 49, the petroleum coke blocks are put in. The falling petroleum coke blocks will contact the second elastic blocks 50 on the inclined surfaces of the second bent rods 49, and then will be thrown to the rebound crushing assembly inside the vibration cone 11. The petroleum coke blocks will contact the multiple crushing tooth surfaces 53 and the rubber elastic balls 52 on the end surface of the arc surface block 29 inside the rebound crushing assembly. The arc surface block 29 subjected to the impact pressure will drive the elastic rod 25 and the linkage elastic plate 24 at one end to retract inward, so that a plurality of first springs 23 inside the vibration base 22 are stressed to generate vibration. At this time, if the petroleum coke blocks contact the rubber elastic balls 52, they will be quickly elastically rebounded to the surface of the elastic net 43. The quickly bouncing petroleum coke blocks can also throw out the internal moisture to improve the drying effect. If they contact the crushing tooth surfaces 53, the quickly vibrating arc surface block 29 will drive the tooth surfaces of the crushing tooth surfaces 53 to crush the petroleum coke blocks, thereby improving the subsequent drying effect.

[0044] The rapidly rotating rotating disk 28 and the second bending rod 49 will also cause the petroleum coke blocks to disperse quickly, preventing them from accumulating in a certain corner of the elastic net 43 and avoiding uneven drying. The scattered petroleum coke blocks will fall onto the umbrella cover drying assembly. When the petroleum coke blocks are scattered in the area of the elastic net 43 and the second ventilation pipe 55 between the elastic nets 43, the first air seat 30 will be activated at this time. The first air seat 30 will inject gas into the interior through the first intake pipe 20. Multiple first heating blocks 31 arranged in the first air seat 30 will also start heating. The first heating blocks 31 will heat the gas entering the first air seat 30. The heated gas will enter into multiple first ventilation pipes 44 through multiple connecting hoses 54. The second heating blocks 46 arranged in the first ventilation pipes 44 will also be activated to perform secondary heating treatment on the gas. The gas after heating will enter into the connected second ventilation pipe 55. The gas entering the second ventilation pipe 55 will cause the overall outer shell to heat up. The second ventilation pipe 55 will conduct the heat to the connected heat conduction patch 56, so that a certain amount of heat will be generated on the elastic net 43 below the heat conduction patch 56. When the petroleum coke blocks fall onto the elastic net 43, they can be quickly dried due to the surface temperature. While the surface temperature of the elastic net 43 rises, the hot gas entering the second ventilation pipe 55 will also enter into the connected jet seat 66. Multiple second jet openings 67 arranged on the outer circumferential surface of the jet seat 66 will also open, thus spraying out hot gas. Since there are many holes inside the petroleum coke blocks, the hot gas can effectively flow rapidly inside them, thereby quickly drying the inside of them.

[0045] When the petroleum coke blocks are dried on the surface of the elastic net 43, since the elastic net 43 is made of flexible material, the petroleum coke blocks cannot roll down due to friction. At this time, multiple vibrators 58 arranged on the surface of the inclined bottom plate 57 will be activated. The output ends of the vibrators 58 cause the attached elastic net 43 to start vibrating, so that the relatively light petroleum coke blocks that have been dried on the surface of the elastic net 43 can roll down, and then roll through the material dropping port 59 to the grinding conical wall 39 in the grinding assembly below. During the vibration of the vibrators 58, if the petroleum coke blocks cannot drop effectively, the first drive motor 17 can drive the rotating main shaft 16 and the preparation cylinder 10 to shake left and right, so that the petroleum coke blocks can drop.

[0046] When the petroleum coke block drops onto the surface of the grinding cone wall 39, the petroleum coke block will drop onto the area between the grinding cone wall 39 and the grinding cone block 38 according to its inclined surface. At this time, the third driving motor 33 will be started. The output end of the third driving motor 33 drives the second gear 36 to rotate, thereby driving the meshing second toothed ring 35 to rotate, and then driving the rotating air shaft 34 arranged at the center of the second toothed ring 35 and the grinding cone block 38 at one end of the rotating air shaft 34 to rotate. The rotating grinding cone block 38 drives the first grinding surface 40 on the outer circular surface to relatively grind against the second grinding surface 41 on the surface of the grinding cone wall 39. The petroleum coke block that drops between the grinding cone wall 39 and the grinding cone block 38 will break and drop downward into the blanking tray 42. When the powder of the petroleum coke block in the blanking tray 42 accumulates, the staff can pull out the blanking tray 42 outward along the sliding opening 45 to pour it out.

[0047] Embodiment 2:

[0048] On the basis of Embodiment 1, a further embodiment is made, such as Figure 4 and Figure 10 As shown, a plurality of stirring air pipes 60 are uniformly communicated along the circumferential direction on the outer circular surface of the rotating air shaft 34 above the grinding cone block 38. One end of the stirring air pipe 60 away from the rotating air shaft 34 extends to the funnel opening formed by the grinding cone block 38 and the grinding cone wall 39. A first air jet port 61 is communicated on the bottom end surface of the stirring air pipe 60 extending to the funnel. On one side of the first air jet port 61, a connecting plate 62 is arranged on the end surface of the stirring air pipe 60 away from the rotating air shaft 34. One end of a rotating inner rod 63 is connected to the bottom end surface of the connecting plate 62. The other end of the rotating inner rod 63 extends into the funnel opening. A rotating outer cylinder 64 is rotatably arranged on the outer circular surface of the rotating inner rod 63 extending into the funnel opening. A plurality of wave plates 65 are uniformly arranged along the circumferential direction on the outer circular surface of the rotating outer cylinder 64. Above the stirring air pipe 60, a second air inlet pipe 21 is communicated on the outer circular surface of one side of the second air seat 32.

[0049] During the crushing process of the petroleum coke block, the rotating rotating air shaft 34 will also drive the stirring and venting rod 60 and the connecting plate 62 at one end of the stirring and venting rod 60 to rotate in the grinding cone wall 39, thereby driving the rotating inner rod 63 provided at one end of the bottom of the connecting plate 62 and the rotating outer cylinder 64 on the outer circumference of the rotating inner rod 63 to rotate. When the rotating outer cylinder 64 is driven by the rotating inner rod 63 to rotate at the funnel between the grinding cone wall 39 and the grinding cone block 38, it will also rotate on its own, thereby driving the multiple undulating plates 65 provided on the outer circumference of the rotating outer cylinder 64 to rotate. The undulating plate 65 will stir the petroleum coke blocks at the funnel to prevent the petroleum coke blocks from being blocked at the funnel. During the rotation of the stirring and venting rod 60, the second air seat 32 will also inject gas through the second air inlet pipe 21. The second air seat 32 will inject the injected gas into the stirring and venting rod 60 through the hole in the middle of the rotating air shaft 34, and then spray it to the funnel through the first air jet 61 at the bottom of the stirring and venting rod 60, so that the partially blocked powder that has been finely ground can be blown away, preventing the powder from sticking to the first grinding surface 40 and the second grinding surface 41, thereby improving the crushing and grinding effect.

[0050] Example 3:

[0051] On the basis of embodiment 1 or 2, further embodiments are made, such as Figure 4 、 Figure 5 and Figure 6 As shown, a plurality of first bending rods 47 bent outward and spread out are evenly connected along the circumferential direction on the upper end surface of the rotating disk 28 between the plurality of second bending rods 49, a plurality of first elastic blocks 48 are evenly arranged along the straight line direction on the upper end inclined surface of the plurality of first bending rods 47 near the feed pipe port 12, and a plurality of elastic ropes 51 are evenly connected along the contour line direction between the plurality of first bending rods 47.

[0052] When the second bending rod 49 rotates rapidly and tosses the petroleum coke blocks, since the diameter of the second bending rod 49 is smaller when it bends upward, some of the scattered petroleum coke blocks will not come into contact with the second bending rod 49. Therefore, a first bending rod 47 and an elastic rope 51 are set on the surface of the rotating disk 28. During the rotation of the second bending rod 49, the first bending rod 47 and the elastic rope 51 will also rotate rapidly due to the rotating disk 28. If some of the petroleum coke blocks that are not in contact with the second bending rod 49 fall on the first elastic block 48 on the surface of the first bending rod 47, they will be quickly thrown out by the first elastic block 48 and fall onto the elastic rope 51. Because there are multiple elastic ropes 51 and they are relatively elastic, they will be driven by them to rotate several times. They will not be thrown out until they roll onto the outermost elastic rope 51. In this relationship, the gas flow inside the rotating petroleum coke blocks is infinitely accelerated, which can effectively remove the internal moisture.

[0053] The above is only the preferred embodiment of the present application. Although the present application has been disclosed above in a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present application. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application still fall within the scope of protection of the technical solution of the present application.
