Description

Technical Field

[0001] This invention relates to the field of horizontal ground tanks, and in particular to a material receiving ground tank structure. Background Technology

[0002] When treating chemical sludge waste, the sludge waste and various neutralizing agents are put into a mixing tank together. The mixing tank allows the various neutralizing agents and sludge waste to come into full contact, thereby neutralizing the harmful components in the sludge waste.

[0003] Chinese Patent Publication No. CN206823595U discloses a horizontal mixing device, including a mixing tank, a drive motor, a rotating main shaft, a stirrer, and a material circulation system. The mixing tank has a feed inlet at the top center and a discharge inlet at the bottom center. Stirring blades are mounted on the rotating main shaft.

[0004] Before mixing the materials, they need to be added into the mixing tank through the feed port. When the materials are added into the mixing tank, they tend to accumulate below the feed port and cannot be evenly distributed inside the mixing tank. This prevents some of the mixing blades from fully performing their mixing function, resulting in poor mixing effect. Summary of the Invention

[0005] This application provides a material receiving tank structure, which has the advantage of good material mixing effect.

[0006] The material receiving tank structure provided in this application adopts the following technical solution:

[0007] A material receiving tank structure includes a tank body, with a material inlet at the top and a material outlet at the bottom. A rotating shaft is rotatably connected to the tank body, and the rotating shaft passes through the tank body along its length. The tank body is also provided with a drive unit for driving the rotating shaft to rotate. The rotating shaft is provided with a spiral inner hinge and several fixed shafts on the shaft body located inside the tank body. Each of the fixed shafts is provided with a stirring blade at the end away from the rotating shaft.

[0008] By adopting the above technical solution, after the material is fed into the tank through the feeding port, the drive unit first drives the rotating shaft to rotate forward. The rotation of the shaft drives the inner hinge and the stirring blades to rotate, pushing and stirring the material in the forward direction. Then, the drive unit drives the rotating shaft to rotate in reverse, causing the inner hinge and the blades to rotate, pushing and stirring the material in the reverse direction. Through the reciprocating pushing and stirring of the material, the material is less likely to accumulate below the feeding port, thus allowing the blades to effectively perform their stirring function and resulting in better mixing of the materials.

[0009] Preferably, the tank body is also provided with a through pipe, the top end of which extends out of the tank body. The pipe body located inside the tank body is provided with a plurality of through holes that connect the inner cavity of the through pipe to the outside. The plurality of through holes are equidistantly distributed on the through pipe along the length direction of the through pipe.

[0010] By adopting the above technical solution, hot air is injected into the pipe during material mixing, allowing the hot air to enter the material through the through-hole. The hot air heats and softens the mud, enabling the mud waste to mix more evenly with various neutralizing agents, thus ensuring the neutralization effect of the various neutralizing agents on the mud. When cleaning the inner wall of the tank, water can be added to the tank to rinse the impeller and the inner tank wall.

[0011] Preferably, there are multiple through pipes, which are located on both sides of the inner hinge and several fixed shafts, and the openings of the several through holes all face the center of the tank.

[0012] By adopting the above technical solution, the resistance of the constantly tumbling material to the hot air entering the material is reduced, and the movement direction of the hot air and water is guided to ensure the softening effect of the hot air on the mud, while enhancing the cleaning effect of the cleaning water on the blades.

[0013] Preferably, the drive unit is a geared motor, one end of the tank is provided with a bottom valve, and the other end is provided with a frame for mounting the motor. The bottom valve is provided with a mounting plate on the side away from the tank. Both the mounting plate and the frame are provided with bearings, and the two ends of the rotating shaft are respectively provided on two bearings.

[0014] By adopting the above technical solutions, the bearing can provide better balanced support for the shaft, making the shaft and blades more stable during operation.

[0015] Preferably, a PTFE packing is provided between the mounting plate and the bottom valve, and a plurality of rubber O-rings are provided between the rotating shaft and the mounting plate.

[0016] By adopting the above technical solution, several rubber O-rings and PTFE packings possess resilience, allowing them to spring back and fill even after wear during use, ensuring the sealing of the joints between various components. Simultaneously, during material feeding, the material exerts a certain impact on the shaft; the rubber O-rings and PTFE packings help buffer some of this impact force, thereby reducing shaft wear and extending its service life.

[0017] Preferably, each of the fixed shafts is provided with a mounting seat, and each of the mounting seats has a mounting groove on the side facing the rotating shaft. Two mounting rods are hinged to each of the mounting grooves. Each of the two mounting rods in the same mounting groove has a number of bristles on the side that is far away from each other. Each of the fixed shafts is provided with a control mechanism, which is used to control the rotation of the mounting rods so that the bristles abut against the inner wall of the tank.

[0018] By adopting the above technical solution, during tank cleaning, the control mechanism rotates the mounting rod, causing the bristles on the mounting rod to come into contact with the inner wall of the tank. As the fixed shaft rotates, several bristles scrub the inner wall of the tank, brushing off the material adhering to it. When the tank is agitating materials, the control mechanism retracts the rotating rod, reducing the impact of the rotating rod and bristles on the rotation of the fixed shaft.

[0019] Preferably, each of the mounting seats has a first sliding groove on its side facing the rotating shaft. The control mechanism includes two levers slidably connected to a fixed shaft, a control component for controlling the movement of the two levers, a first slider slidably connected in the first sliding groove, several first springs disposed on the bottom wall of the first sliding groove, and a pressing block slidably connected to the side of the mounting seat facing the rotating shaft. The movement paths of the two levers are respectively located on both sides of the mounting seat. Both sides of the first slider have protrusions forming protrusions, and the two protrusions are respectively located on the movement paths of the two levers. A first inclined surface is formed on the side of the first slider facing the mounting groove. The distance from the first inclined surface to the mounting groove gradually decreases from the side away from the rotating shaft to the side closer to the rotating shaft. An I-shaped groove is formed on the first inclined surface along its length. The pressing block is located between the first slider and the mounting groove, and the pressing block faces the first slider. One side of the device has a second inclined surface that fits against the first inclined surface. A second slider is provided on the second inclined surface. The second slider is slidably connected in the I-shaped groove. The side of the pressing block facing the mounting groove has a conical block protruding. One end of each of the first springs is fixedly connected to the bottom end of the first slider, and the other end is fixedly connected to the bottom wall of the first groove. When the fixed shaft stirs the material, the two levers are located on both sides of the non-hinged ends of the two mounting rods and abut against the bristles on the two mounting rods. The conical block is located between the two mounting rods and abuts against the two mounting rods. When the two levers move to contact the two protrusions, the two levers are located below the mounting groove. When the two levers move to the position closest to the inner wall of the tank, the pressing block is located above the mounting groove and presses the two mounting rods against the bottom wall of the mounting groove. Several bristles on the two mounting rods abut against the inner wall of the tank.

[0020] By adopting the above technical solution, when the tank needs to be cleaned, the drive assembly drives the lever to move towards the mounting base. During the movement of the lever, it first contacts the protrusion, and then moves towards the bottom wall of the first slide groove along with the protrusion and the first slider. When the first slider moves, it compresses several first springs and pushes the pressing block and the cone block away from the fixed axis. During the movement of the pressing block and the cone block, the cone block pushes the two mounting rods to rotate and move away from each other. Finally, the pressing block moves to the top of the mounting groove and presses the mounting rod against the bottom wall of the mounting groove, causing several bristles to contact the inner wall of the tank. After the tank is cleaned, the lever moves back to its original position under the action of the drive assembly, so that the lever gradually stops pressing against the protrusion. During this process, several first springs will rebound and drive the first slider to move back to its original position. The first slider's movement and reset will drive the pressing block and the cone block to move back to their original position through the cooperation of the I-shaped groove and the second slider. After the lever moves away from the protrusion, it will contact the rotating rod and drive the rotating rod to flip and reset.

[0021] Preferably, a first air intake chamber is formed on one end face of the rotating shaft along the axial direction of the rotating shaft, and a second air intake chamber is formed in each of the plurality of fixed shafts. The first air intake chamber communicates with the plurality of second air intake chambers. A through groove is formed on the side wall of the second air intake chamber along the axial direction of the fixed shaft. The control component includes a third slider slidably connected in the second air intake chamber, a connecting plate disposed on the third slider, a second spring disposed in the second air intake chamber, and an air compressor for delivering air into the first air intake chamber. The top end of the connecting plate is connected to the third slider. The bottom surface of the first air intake chamber is connected to the second air intake chamber, and the other end extends through the through groove and is connected to the two levers. One end of the second spring abuts against the bottom wall of the second air intake chamber, and the other end abuts against the second spring. The second spring is always in a compressed state. When the air compressor does not provide compressed gas to the first air intake chamber, the connecting plate abuts against the end of the through groove closest to the rotating shaft. When the air compressor provides compressed gas to the first air intake chamber, the connecting plate moves to abut against the end of the through groove away from the rotating shaft, and the third slider is located between the through groove and the rotating shaft.

[0022] By adopting the above technical solution, when the air compressor starts, it forces air into the first and second intake chambers. When the air enters the second intake chamber, it pushes the third slider to slide away from the rotating shaft. The sliding of the third slider causes the connecting plate to move and compresses the second spring. The movement of the connecting plate then moves the lever. When the air compressor stops supplying compressed gas, the second spring rebounds, causing the third slider and connecting plate to reset. The reset of the connecting plate then resets the lever.

[0023] Preferably, each of the aforementioned levers is provided with a plurality of conical pointed blocks.

[0024] By adopting the above technical solution, several conical tips will scrape off the material adhering to the bristles during the movement of the lever, preventing the material from sticking to the bristles.

[0025] Preferably, the inner wall of the tank is provided with a fixed seat, and the fixed seat has a first sliding hole on the side facing the rotating shaft. A push rod is slidably connected in the first sliding hole. The discharge port is located on the movement path of the push rod. A second sliding hole is provided on the side wall of the first sliding hole. An annular stop is provided on the push rod, and the annular stop is slidably connected in the second sliding hole. A third spring is also provided in the second sliding hole. One end of the third spring abuts against the bottom wall of the third sliding hole, and the other end abuts against the annular stop. A third inclined surface is provided at the top of the push rod. The rotating shaft is also provided with a mounting shaft. A third intake chamber, connected to the first intake chamber, is provided within the mounting shaft. A fourth slider is slidably connected within the third intake chamber. A push rod is mounted on the fourth slider, with one end of the push rod extending out of the mounting shaft away from the fourth slider. A fourth spring is provided within the third intake chamber, with one end of the fourth spring contacting the bottom wall of the third intake chamber and the other end contacting the fourth slider. When the air compressor does not provide compressed gas to the first intake chamber, the third inclined surface is not on the rotation path of the push rod. When the air compressor provides compressed gas to the first intake chamber, the third inclined surface is on the rotation path of the push rod.

[0026] By adopting the above technical solution, when the air compressor starts, air is forced into the third intake chamber and pushes the fourth slider towards the bottom wall of the third intake chamber. The movement of the fourth slider compresses the fourth spring and extends the push rod from the mounting shaft, placing the third inclined surface on the rotation path of the push rod. Therefore, when the fixed shaft rotates, the push rod first collides with the third inclined surface and pushes the top rod towards the discharge port. The movement of the top rod drives the annular stop block, compressing the third spring. Simultaneously, the movement of the top rod pushes the material into the discharge port, preventing material accumulation and blockage. When the push rod rotates away from the top rod, the third spring rebounds, causing the annular stop block and the top rod to reset. During the rotation of the push rod, it continuously pushes the top rod towards the discharge port.

[0027] The main technical effects of this invention are reflected in the following aspects:

[0028] 1. This invention uses the rotation of the inner hinge and the stirring blades to push and stir the material, thereby ensuring that the material is fully mixed and in contact;

[0029] 2. This invention allows hot air and cleaning water to enter the interior of the tank by setting up a through pipe, which improves the quality of material mixing and also facilitates the cleaning of the tank.

[0030] 3. This invention uses bearings to support the rotating shaft, making the shaft and agitator more stable during operation. Multiple layers of rubber O-rings and PTFE packing are used to ensure the sealing of the connections between components and reduce wear on the rotating shaft. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this application can be more easily understood and mastered.

[0042] This embodiment of a material receiving tank structure includes a tank body 1. The tank body 1 has a feed inlet 11 at the top and a discharge outlet 12 at the bottom. A rotating shaft 2 is rotatably connected to the tank body 1, passing through it. The rotating shaft 2 extends through the tank body 1 along its length. A bottom valve 14 is fixedly connected to one end of the tank body 1, and a frame 15 is fixedly connected to the other end. A drive unit 3, which is a geared motor 31, is fixedly connected to the frame 15 to drive the rotating shaft 2. A mounting plate 16 is installed on the side of the bottom valve 14 away from the tank body 1. Bearings 17 are fixedly connected to both the mounting plate 16 and the frame 15. The two ends of the rotating shaft 2 extending out of the tank body 1 are respectively fixed to the inner rings of the two bearings 17.

[0043] A spiral-shaped inner hinge 21 and several fixed shafts 22 are fixedly connected to the shaft body inside the tank 1. The axes of the fixed shafts 22 are all perpendicular to and intersect the axis of the shaft 2. A stirring blade 23 is fixedly connected to the end of each fixed shaft 22 away from the shaft 2. Two through pipes 13 are also fixed on the tank 1. The two through pipes 13 are located on both sides of the inner hinge 21 and the fixed shafts 22, respectively. The axes of the two through pipes 13 are perpendicular to the axis of the shaft 2. The top ends of the two through pipes 13 extend out of the tank 1. Several through holes 131 connecting the inner cavity of the two through pipes 13 to the outside are opened on the pipe body inside the tank 1. The through holes 131 are evenly distributed along the length of the through pipe 13, and the openings of the through holes 131 are all set towards the center of the tank 1.

[0044] After the material is fed into the tank 1 through the feeding port, the geared motor 31 first drives the rotating shaft 2 to rotate forward. The rotation of the rotating shaft 2 drives the inner hinge 21 and the stirring blade 23 to rotate, pushing and stirring the material in the forward direction. Then, the geared motor 31 drives the rotating shaft 2 to rotate in reverse, causing the inner hinge 21 and the blade to rotate, pushing and stirring the material in the reverse direction. Through the reciprocating pushing and stirring of the material, the material is less likely to accumulate below the feeding port, allowing the blade to perform its stirring function well and resulting in better mixing of the materials. During the material stirring process, hot air is injected into the through pipe 13, allowing the hot air to enter the material through the through hole 131. The hot air heats and softens the mud, allowing the mud waste to mix more evenly with various neutralizing agents, thus ensuring the neutralization effect of various neutralizing agents on the mud.

[0045] Mounting seats 4 are fixedly connected to the outer walls of several fixed shafts 22 on the side away from the rotating shaft 2. Each mounting seat 4 has a mounting groove 41 along the axis of the fixed shaft 22 on its side facing the rotating shaft 2. Two mounting rods 42 are hingedly connected within each mounting groove 41, and the hinge axis of each mounting rod 42 is perpendicular to both the axis of the fixed shaft 22 and the axis of the rotating shaft 2. Several brush bristles 43 are fixedly connected to the surfaces of the two mounting rods 42 in the same mounting groove 41 that are away from each other.

[0046] Each of the mounting bases 4 has a first sliding groove 44 on its side facing the rotating shaft 2, along the axial direction of the fixed shaft 22. The first sliding grooves 44 are located on the side of the mounting slots 41 closest to the corresponding fixed shaft 22. Each of the fixed shafts 22 is equipped with a control mechanism 6, which controls the rotation of the mounting rods 42 so that the bristles 43 abut against the inner wall of the tank body 1. The control mechanism 6 includes two levers 61 slidably connected to the fixed shaft 22 along its axial direction. The levers 61 are L-shaped, and their movement paths are located on opposite sides of the mounting base 4. The bottom end of each lever 61 is fixedly connected to several conical tips 611.

[0047] The control mechanism 6 also includes a first slider 63 slidably connected in the first slide groove 44, a plurality of first springs 64 fixed on the bottom wall of the first slide groove 44, and a pressing block 65 slidably connected along the hinge axis of the mounting rod 42 on the side of the mounting base 4 facing the rotating shaft 2. Both sides of the first slider 63 protrude outward to form protrusions 631, and the two protrusions 631 are respectively located on the movement path of the two levers 61. A first inclined surface 632 is formed on the side of the first slider 63 facing the mounting groove 41. The distance from the first inclined surface 632 to the mounting groove 41 gradually decreases from the side away from the rotating shaft 2 to the side closer to the rotating shaft 2. An I-shaped groove 633 is formed on the first inclined surface 632 along its length. A pressing block 65 is located between the first slider 63 and the mounting groove 41. A second inclined surface 651 is formed on the side of the pressing block 65 facing the first slider 63, which fits against the first inclined surface 632. A second slider 652 is provided on the second inclined surface 651 and is slidably connected in the I-shaped groove 633. A cone block 653 is formed on the side of the pressing block 65 facing the mounting groove 41. One end of each of the first springs 64 is fixedly connected to the bottom end of the first slider 63, and the other end is fixedly connected to the bottom wall of the first groove 44.

[0048] A first air intake chamber 24 is formed on the end face of the rotating shaft 2 away from the geared motor 31 along the axial direction of the rotating shaft 2. A second air intake chamber 221 is formed in each of the fixed shafts 22. The first air intake chamber 24 connects to the second air intake chambers 221. Through slots 223 are formed on the side walls of the second air intake chambers 221 near the corresponding fixed base 7 along the axial direction of the fixed shaft 22. The control mechanism 6 also includes a control component 62 for controlling the movement of the two levers 61. The control component 62 includes a third slider 621 slidably connected to the second air intake chamber 221 along the length of the fixed shaft 22, a connecting plate 623 fixedly connected to the bottom surface of the third slider 621, and a second spring 622 disposed in the second air intake chamber 221. The top end of the connecting plate 623 is connected to the bottom surface of the third slider 621, and the other end extends through the through slot 223 and is fixedly connected to the top ends of the two levers 61. The body of the connecting plate 623 located inside the fixed shaft 22 is fan-shaped. A fan-shaped blocking plate is also fixedly connected below the connecting plate 623. When the connecting plate 623 moves, the connecting plate 623 and the fan-shaped blocking plate will block the through slot 223 together, thereby preventing materials and cleaning water from entering the second air inlet chamber 221. One end of the second spring 622 abuts against the bottom wall of the second air inlet chamber 221, and the other end abuts against the bottom surface of the third slider 621. The second spring 622 is always in a compressed state.

[0049] The control assembly 62 also includes an air compressor for supplying air into the first intake chamber 24. A vent pipe is fixedly connected to the air outlet of the air compressor, and an air nozzle is fixedly connected to the end of the vent pipe away from the air compressor. A rotating ring is rotatably connected to the opening of the first intake chamber 24, and the air nozzle is fixedly connected to the rotating ring. (The air compressor and its parts are not shown in the figure).

[0050] A fixed seat 7 is fixedly connected to the inner wall of the bottom of the tank body 1. A first sliding hole 71 is vertically formed on the side of the fixed seat 7 facing the rotating shaft 2, located above the storage port. A push rod 8 is vertically connected within the first sliding hole 71, and the discharge port 12 is located on the movement path of the push rod 8. A second sliding hole 72 is vertically formed on the side wall of the first sliding hole 71. An annular stop 81 is fixedly connected to the push rod 8, sliding vertically within the second sliding hole 72. A third spring 73 is also provided within the second sliding hole 72, sleeved on the outside of the push rod 8. One end of the third spring 73 abuts against the bottom wall of the third sliding hole, and the other end abuts against the annular stop 81. A third inclined surface 82 is formed at the top of the push rod 8.

[0051] A mounting shaft 9 is also fixedly connected to the rotating shaft 2. The axis of the mounting shaft 9 is perpendicular to and intersects the axis of the rotating shaft 2. A third air intake chamber 91, which connects to the first air intake chamber 24, is opened inside the mounting shaft 9. A fourth slider 92 is slidably connected to the third air intake chamber 91 along the axial direction of the mounting shaft 9. A push rod 93 is fixedly connected to the side of the fourth slider 92 away from the rotating shaft 2. The axis of the push rod 93 is basically coincident with the axis of the mounting shaft 9. The end of the push rod 93 away from the fourth slider 92 extends out of the mounting shaft 9. A fourth spring 94 is provided inside the third air intake chamber 91. The fourth spring 94 is sleeved on the outside of the push rod 93. One end of the fourth spring 94 abuts against the bottom wall of the second air intake chamber 221, and the other end abuts against the fourth slider 92.

[0052] The cleaning steps for tank 1 in this application are as follows:

[0053] When the air compressor does not provide compressed gas to the first intake chamber 24, several connecting plates 623 abut against the end of the corresponding through groove 223 closest to the rotating shaft 2. Two levers 61 on the same fixed shaft 22 are located on both sides of the non-hinged ends of the corresponding two mounting rods 42 and abut against the bristles 43 on the corresponding mounting rods 42. The cone block 653 is located between the corresponding two mounting rods 42 and abuts against the corresponding two mounting rods 42. The annular stop block 81 is pressed against the side wall of the second sliding hole 72 near the rotating shaft 2 by the third spring 73. The third inclined surface 82 is not on the movement trajectory of the push rod 93.

[0054] When tank 1 needs cleaning, water is injected into tank 1 through two pipes 13, and the air compressor is started at the same time. After the air compressor starts, it forces air into the first air intake chamber 24, the second air intake chamber 221, and the third air intake chamber 91. When the air is forced into the second air intake chamber 221, the air will push the third slider 621 to slide away from the rotating shaft 2. When the third slider 621 slides, it will drive the connecting plate 623 to move and cause the second spring 622 to be compressed. When the connecting plate 623 moves, it will drive the lever 61 to move towards the fixed seat 7.

[0055] During the movement of lever 61, some material on brush bristles 43 will be cleaned. When lever 61 moves to the bottom of mounting groove 41, lever 61 will first abut against protrusion 631, and then move protrusion 631 and first slider 63 toward the bottom wall of first slide groove 44. When the first slider 63 moves, it will cause some first springs 64 to be compressed and push the pressing block 65 and cone block 653 to move away from fixed shaft 22. During the movement of pressing block 65 and cone block 653, cone block 653 will first push two mounting rods 42 to rotate away from each other. When connecting plate 623 moves to abut against the side wall of through groove 223 away from rotating shaft 2, pressing block 65 will move above mounting groove 41 and press mounting rods 42 against the bottom wall of mounting groove 41, so that some brush bristles 43 abut against the inner wall of tank 1. As the fixed shaft 22 rotates, several bristles 43 will scrub the inner wall of the tank 1, causing the material adhering to the inner wall of the tank 1 to be brushed off.

[0056] When air is forced into the third intake chamber 91, it pushes the fourth slider 92 towards the bottom wall of the third intake chamber 91. The movement of the fourth slider 92 compresses the fourth spring 94 and causes the push rod 93 to extend from the mounting shaft 9, positioning the third inclined surface 82 on the rotation path of the push rod 93. As the push rod 93 rotates, it collides with the third inclined surface 82 and pushes the top rod 8 towards the discharge port 12. The movement of the top rod 8 causes the annular stop block 81 to move, compressing the third spring 73. Simultaneously, the movement of the top rod 8 pushes the material into the discharge port 12, preventing material accumulation and blockage. During the rotation of the push rod 93, it continuously pushes the top rod 8 towards the discharge port 12, continuously pushing the material into the discharge port 12.

[0057] After tank 1 is cleaned, the air compressor is turned off and the gas in the first air inlet chamber 24 is discharged. Without air pressure, the second spring 622 will rebound and drive the third slider 621 and connecting plate 623 to reset. When the connecting plate 623 resets, it will drive the lever 61 to reset, so that the lever 61 gradually stops pressing against the protrusion 631. During this process, several first springs 64 will rebound and drive the first slider 63 to reset. When the first slider 63 resets, it will drive the pressing block 65 and the cone block 653 to reset through the cooperation of the I-beam groove 633 and the second slider 652. When the lever 61 moves to the point where it no longer presses against the protrusion 631, the pressing block 65 and the cone block 653 will also move to their initial positions.

[0058] Then the lever 61 will continue to move and reset, and drive the mounting rod 42 to rotate. During this process, the lever 61 will scrape off the material attached to the bristles 43. When the connecting plate 623 moves to the end of the through groove 223 closest to the rotating shaft 2, the lever 61 will stop moving. At this time, the mounting rod 42 is also clamped and positioned by the lever 61 and the fastener, reducing the influence of the mounting rod 42 and several bristles 43 on the material mixing.

[0059] Without air pressure, the fourth spring 94 will rebound and drive the fourth slider 92 to move and reset. When the fourth slider 92 moves and resets, it will cause the push rod 93 to retract into the mounting shaft 9, so that the push rod 93 will no longer collide with the third inclined plane 82 during rotation.

[0060] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
