Description

Technical Field

[0001] This application relates to the technical field of denitration devices, and particularly to a denitration device for fluidized bed boilers. Background Art

[0002] At present, as an efficient and environmentally friendly boiler, the circulating fluidized bed boiler plays an indispensable role in the flexible operation of power grid peak shaving. However, during ultra-low load operation, the internal temperature of the boiler decreases, and the temperature in the dilute phase zone of the boiler cannot meet the working conditions of the SNCR denitration system. As a result, when the circulating fluidized bed boiler operates within the range of 15-50% of the rated load, the NOx emissions of the boiler exceed the standard and cannot meet the national environmental protection requirements. For this reason, a forced in-furnace denitration device for circulating fluidized bed boilers operating at ultra-low loads is disclosed in related technologies (publication number: CN114459023B), which uses impact jet nozzles, tangential circle nozzles on four walls, and tangential circle jet nozzles at four corners to form a forced rigid disturbance multi-dimensional mixing inside the furnace, enabling the flue gas generated during operation to fully react with urea.

[0003] In the process of implementing the technical solutions of the present disclosure, it is found that at least the following problems exist in related technologies: For the forced in-furnace denitration device of circulating fluidized bed boilers operating at ultra-low loads, a first cylinder or actuator is used to drive a first slider to move, and at the same time, a second cylinder or actuator is used to drive a second slider to move, ultimately changing the spraying angle of the regulating nozzle. By converting the nozzle angle, a gas vortex is formed inside the furnace, enabling urea to fully mix with the flue gas and ultimately improving the denitration efficiency. However, due to the structure of the driving components, the angle adjustment range of the nozzle is limited, thereby affecting the mixing effect of solutions such as urea or ammonia water with the flue gas.

[0017] A denitration device for fluidized bed boiler treatment provided by the technical solution of the present disclosure can achieve the following technical effects: 1. Driven by the driving member and transmitted by the transmission member, the multiple columns of hollow shafts and the multiple columns of rotating shafts around the circumference can revolve around the axis of the first spline sleeve, rotate along their own axes, and also move in the radial direction of the treatment cylinder. Therefore, the angle adjustment range of the spraying member and the mixing member is increased. That is, it helps the solutions such as urea or ammonia water to be evenly sprayed inside the treatment cylinder, and also helps the flue gas to be evenly dispersed inside the treatment cylinder. The mixing effect of the solution such as urea or ammonia water and the flue gas is improved, enabling the flue gas to fully react with the solution such as urea or ammonia water.

[0018] 2. By controlling the operation of a single first motor, the functions of the multiple columns of hollow shafts and the multiple columns of rotating shafts around the circumference to continuously rotate around the axes of the multiple columns of first spline sleeves respectively can be realized. That is, it can rotate freely, increasing the angle adjustment range. Also, the number of power sources is reduced, and complex electrical interlock control is not required, reducing the risk of failure.

[0019] 3. By controlling the operation of a single second motor, the functions of the multi-column hollow shafts and multi-column rotating shafts on all sides rotating around their respective axes can be achieved. That is, they can rotate freely, improving the angle adjustment range. Also, the number of power sources is reduced, eliminating the need for complex electrical interlock control and reducing the risk of failures.

[0020] 4. By controlling the operation of a single third motor, the functions of the multi-column hollow shafts and multi-column rotating shafts on all sides reciprocatingly moving in the radial direction of the processing cylinder can be achieved.

[0021] 5. The mixing member adopts a design with multiple straight blades and multiple L-shaped blades. The straight blades can push the flue gas and water vapor to flow along the axial direction of the rotating shaft, and the L-shaped blades can push the flue gas and water vapor to flow along the radial direction of the rotating shaft, thereby forming a dispersed flow path. Moreover, under the drive of the driving member, after multiple mixing members rotate around the common center, rotate on their own axes and move, the flow paths can intersect, separate or overlap with each other, further improving the mixing effect of the flue gas and water vapor.

[0022] 6. The spraying member adopts a design with a cylindrical seat and multiple nozzles. Under the drive of the driving member, after multiple nozzles rotate around the common center, rotate on their own axes and move, a movable spherical spraying area can be formed. Moreover, multiple rows of spraying members on all sides perform spraying operations together, and spherical spraying areas that can intersect, separate or overlap with each other can be formed inside the processing cylinder, enabling solutions such as urea or ammonia water to be evenly dispersed inside the processing cylinder, further improving the mixing effect with the flue gas.

[0023] 7. Through the design of multiple first round tubes and multiple first rotary joints, the supply pipeline of the supply device will not rotate along with the rotation of the multiple second hollow spline shafts, thus avoiding problems such as pipeline entanglement.

[0035] Combined with Figures 1 to 12 As shown, the embodiments of the present disclosure provide a denitration device for fluidized bed boiler treatment, including a treatment cylinder 1, a first spline sleeve 2, a first hollow spline shaft 3, a box body 4, a spraying member, a mixing member, a second hollow spline shaft 7, a transmission member and a driving member. The first spline sleeve 2 is rotatably disposed through the side wall of the treatment cylinder 1 along the radial direction of the treatment cylinder 1, and is uniformly distributed around the treatment cylinder 1. Along the height direction of the treatment cylinder 1, a plurality of first spline sleeves 2 are distributed in columns from top to bottom. The first spline sleeves 2 in multiple columns around are all used to support and install the slidable first hollow spline shaft 3. The first hollow spline shafts 3 are respectively slidably disposed through the first spline sleeves 2 in multiple columns around, and can slide relative to the first spline sleeves 2 in multiple columns around respectively, and rotate under the drive of the first spline sleeves 2 in multiple columns around. The box bodies 4 are respectively installed on the first hollow spline shafts 3 in multiple columns around, and are all located inside the box bodies 4, and rotate under the drive of the first hollow spline shafts 3 in multiple columns around respectively. The spraying member is used to spray solutions such as urea or ammonia water, and includes hollow shafts 5 respectively rotatably installed on the side walls of the box bodies 4 in multiple columns around. The axes of the hollow shafts 5 in multiple columns around are respectively perpendicular to the axes of the first spline sleeves 2 in multiple columns around. The mixing member is used to stir the flow of flue gas or water vapor, and includes rotating shafts 6 respectively rotatably installed on the side walls of the box bodies 4 in multiple columns around. The axes of the rotating shafts 6 in multiple columns around coincide with the axes of the hollow shafts 5 in multiple columns around respectively. The second hollow spline shafts 7 are respectively rotatably installed on the side walls of the box bodies 4 in multiple columns around, and can respectively perform rotational motion relative to the box bodies 4 in multiple columns around. The second hollow spline shafts 7 respectively pass through the interiors of the first hollow spline shafts 3 in multiple columns around, and can respectively rotate inside the first hollow spline shafts 3 in multiple columns around. One ends of the second hollow spline shafts 7 in multiple columns around are respectively communicated with a supply device, and the supply device is used to provide solutions such as urea or ammonia water. The other ends of the second hollow spline shafts 7 in multiple columns around are respectively communicated with the hollow shafts 5 in multiple columns around, so that the solutions such as urea or ammonia water enter the hollow shafts 5 in multiple columns around respectively after passing through the second hollow spline shafts 7 in multiple columns around, and are finally sprayed out through the spraying members in multiple columns around. The transmission members are respectively located in the box bodies 4 in multiple columns around, and are respectively used to transmit driving force, so that the hollow shafts 5 in multiple columns around and the rotating shafts 6 in multiple columns around rotate along with the rotation of the second hollow spline shafts 7 in multiple columns around. The driving member is located outside the treatment cylinder 1, and is used to provide driving force to drive the rotation of the first spline sleeves 2 in multiple columns around, the sliding of the first hollow spline shafts 3 in multiple columns around, and the rotation of the second hollow spline shafts 7 in multiple columns around.

[0036] A denitration device for fluidized bed boilers provided by an embodiment of the present disclosure. Under the supply of a supply device, solutions such as urea or ammonia water can enter the interior of the spray head 32 through the second hollow spline shaft 7 and the hollow shaft 5, and finally be sprayed out. During the spraying process, driven by a driving member, multiple columns of first spline sleeves 2 around the perimeter rotate, multiple columns of first hollow spline shafts 3 around the perimeter slide, and multiple columns of second hollow spline shafts 7 around the perimeter rotate. When the multiple columns of first spline sleeves 2 around the perimeter rotate, they can drive the multiple columns of first hollow spline shafts 3 around the perimeter to rotate, thereby driving the multiple columns of boxes 4 around the perimeter to rotate. Eventually, the multiple columns of hollow shafts 5 and the multiple columns of rotating shafts 6 around the perimeter continuously rotate around the axes of the multiple columns of first spline sleeves 2. When the multiple columns of second hollow spline shafts 7 around the perimeter rotate, driven by a transmission member, they can drive the multiple columns of hollow shafts 5 and the multiple columns of rotating shafts 6 around the perimeter to rotate around their respective axes. When the multiple columns of first hollow spline shafts 3 around the perimeter slide, they can drive the multiple columns of boxes 4 around the perimeter to slide, and finally drive the multiple columns of hollow shafts 5 and the multiple columns of rotating shafts 6 to slide in the radial direction of the treatment cylinder 1. Therefore, driven by the driving member, the multiple columns of hollow shafts 5 and the multiple columns of rotating shafts 6 around the perimeter can revolve around the axis of the first spline sleeve 2, rotate around their own axes, and also move in the radial direction of the treatment cylinder 1. Therefore, the angle adjustment range of the spraying member and the mixing member is increased. That is, it helps the solutions such as urea or ammonia water to be evenly sprayed inside the treatment cylinder 1, and also helps the flue gas to be evenly dispersed inside the treatment cylinder 1. The mixing effect of the solutions such as urea or ammonia water and the flue gas is improved, enabling the flue gas to fully react with the solutions such as urea or ammonia water.

Therefore, through a single first motor 12, the functions of the hollow shafts 5 of multiple columns around the circumference and the rotating shafts 6 of multiple columns around the circumference to continuously rotate around the axes of the first spline sleeves 2 of multiple columns around the circumference can be realized. That is, it can rotate freely, increasing the angle adjustment range.

[0050] In the embodiment of the present disclosure, after any one of the second spline sleeves 15 in any row is controlled to rotate, driven by the second synchronous pulley 16 and the second toothed belt in the same row, the second spline sleeves 15 in the same row area can rotate synchronously. Then, driven by the transmission members in the same row, the hollow shafts 5 and the rotating shafts 6 in the same row can continuously rotate, realizing the function of free rotation. And, since the positions of the multiple support plates 14 remain unchanged, the positions of multiple rows of second spline sleeves 15 around remain unchanged. This enables the corresponding power source to be installed at a fixed position of the device without moving therewith, thus facilitating the routing of wires.

[0051] Optionally, as shown in Figure 1 , Figure 5 , Figure 6 and Figure 7 it further includes a fifth bearing seat and a sixth bearing. The fifth bearings are respectively mounted on the multiple support plates 14 and are respectively sleeved on multiple rows of second spline sleeves 15 around. The sixth bearings are respectively mounted between multiple rows of fifth bearing seats around and multiple rows of second spline sleeves 15 around.

[0052] In the embodiment of the present disclosure, after the fifth bearing seats are respectively mounted on the multiple support plates 14, they are respectively used to support and install multiple rows of sixth bearings around and limit multiple rows of sixth bearings around. Multiple rows of sixth bearings are used to support and install multiple rows of rotatable second spline sleeves 15 around, reduce the friction force received by multiple rows of rotating shafts 6 around, and improve the rotational accuracy of multiple rows of rotating shafts 6 around.

[0053] Optionally, as shown in Figure 1 and Figure 7As shown in the figure, the driving member further includes a second bevel gear 17, a second cylindrical member 18, a third cylindrical member 19, a second motor 20, and a second spur gear 21. The second bevel gears 17 are respectively installed on the lowermost second spline sleeves 15 in multiple columns around, and are respectively used to drive the lowermost second spline sleeves 15 in multiple columns around to rotate. The second cylindrical member 18 is installed on the top surface of the annular plate 11 and sleeved on multiple support plates 14, and is used to support and install the rotatable third cylindrical member 19.

The second motor 20 is installed on the top surface of the annular plate 11, and the rotating end of the second motor 20 passes through the annular plate 11 and is used to provide the driving force. The second spur gear 21 is installed on the rotating end of the second motor 20 and rotates under the drive of the second motor 20. The second spur gear 21 meshes with the second straight tooth to jointly transmit the driving force.

[0054] In the embodiment of the present disclosure, when the second motor 20 is controlled to work, under the meshing action between the second spur gear 21 and the second straight tooth, the third cylindrical member 19 can be driven to rotate. Then, under the meshing action between the second bevel gear and multiple second bevel gears 17, the lowermost second spline sleeves 15 in multiple columns around can be respectively driven to rotate. Then, through the transmission of the second synchronous pulleys 16 in multiple columns around and the second toothed belts in multiple columns around, the remaining second spline sleeves 15 in multiple columns around can rotate synchronously, thereby driving the second hollow spline shafts 7 in multiple columns around to rotate synchronously. Then, through the transmission of the transmission members in multiple columns around, the hollow shafts 5 in multiple columns around and the rotating shafts 6 in multiple columns around can respectively rotate around their axes. That is, they can rotate freely, increasing the angle adjustment range. Also, the number of power sources is reduced, and complex electrical interlock control is not required, reducing the risk of failure.

[0055] Optionally, in combination with Figure 1 , Figure 7 and Figure 8 as shown, a seventh bearing is further included. The seventh bearing is installed between the second cylindrical member 18 and the third cylindrical member 19.

[0056] In the embodiment of the present disclosure, the seventh bearing is used to reduce the friction between the second cylinder and the third cylinder and improve the accuracy when the third cylinder rotates relative to the second cylinder.

[0057] Optionally, in combination with Figure 1 , Figure 7 , Figure 8 , Figure 10 and Figure 12As shown, the driving member further includes a guide rail 22, a slider 23, a support frame 24, a first circular tube 25 and a first rotary joint. The guide rail 22 is installed on the top surface of the annular plate 11 along the radial direction of the processing cylinder 1, and is respectively located below multiple columns of second hollow spline shafts 7 along the height direction of the processing cylinder 1, and is respectively used to support and install a rotatable slide. The sliders 23 are respectively slidably installed on multiple guide rails 22, and jointly play a role of guiding and supporting with the multiple guide rails 22. The support frames 24 are respectively installed on the multiple sliders 23, and can respectively move along the radial direction of the processing cylinder 1 under the guiding and supporting action of the multiple guide rails 22 and the multiple sliders 23.

The first circular tubes 25 are respectively installed on the multiple support frames 24, and are respectively opposite to multiple columns of second hollow spline shafts 7 around, and are respectively used to be connected to the supply pipelines of the supply equipment. The first rotary joints are respectively installed between the opposite first circular tubes 25 and second hollow spline shafts 7, so that the opposite first circular tubes 25 and second hollow spline shafts 7 can rotate relative to each other.

[0058] In the embodiment of the present disclosure, under the guiding and supporting action of the multiple guide rails 22 and the multiple sliders 23, the multiple support frames 24 can respectively move along the radial direction of the processing cylinder 1. Then drive multiple columns of second hollow spline shafts 7 around to move, and then drive multiple columns of boxes 4 around to move along the radial direction of the processing cylinder 1, and at the same time drive multiple columns of first hollow spline shafts 3 to slide relative to multiple columns of first spline sleeves 2. Finally, the function of moving multiple columns of hollow shafts 5 and multiple columns of rotating shafts 6 around along the radial direction of the processing cylinder 1 is realized. Moreover, through the design of the multiple first circular tubes 25 and the multiple first rotary joints, the supply pipelines of the supply equipment will not rotate with the rotation of the multiple second hollow spline shafts 7, thereby avoiding pipeline entanglement and the like.

[0059] Optionally, in combination with Figure 1 、 Figure 5 、 Figure 6 and Figure 7 shown, it further includes a sixth bearing seat and an eighth bearing. The sixth bearings are respectively installed on the multiple support frames 24, and are respectively sleeved on the multiple second hollow spline shafts 7. The eighth bearings are respectively installed between multiple columns of sixth bearing seats around and multiple columns of second hollow spline shafts 7.

[0060] In the embodiments of the present disclosure, after the sixth bearing seats are respectively installed on a plurality of support frames 24, they are respectively used to support and install a plurality of rows of eighth bearings around the circumference, and limit the plurality of rows of eighth bearings around the circumference. The plurality of rows of eighth bearings around the circumference are used to support and install the rotatable plurality of rows of second hollow spline shafts 7 around the circumference, reduce the friction force received by the plurality of rows of second hollow spline sleeves around the circumference, improve the rotation accuracy of the plurality of rows of second hollow spline shafts 7 around the circumference, and enable the plurality of rows of second hollow spline shafts 7 to move under the drive of the plurality of support frames 24.

[0061] Optionally, in combination with Figure 1 、 Figure 7 and Figure 8 shown, the driving member further includes a fourth cylindrical member 26, a fifth cylindrical member 27, a connecting rod 28, a third motor 29 and a third spur gear 30. The fourth cylindrical member 26 is installed on the top surface of the annular plate 11 and is located between a plurality of guide rails 22, and is used to support and install the rotatable fifth cylindrical member 27. The fifth cylindrical member 27 is rotatably installed on the inner wall of the fourth cylindrical member 26 and can rotate relative to the fourth cylindrical member 26. The fifth cylindrical member 27 includes third straight teeth at its bottom. The connecting rod 28 is respectively rotatably installed between the top surface of the fifth cylindrical member 27 and a plurality of support frames 24, and can rotate relative to the fifth cylindrical member 27 and a plurality of support frames 24 respectively. The third motor 29 is installed on the bottom surface of the annular plate 11, and the rotating end of the third motor 29 passes through the annular plate 11 and is used to transmit driving force. The third spur gear 30 is installed on the rotating end of the third motor 29 and rotates under the drive of the third motor 29. The third spur gear 30 meshes with the third straight teeth to jointly transmit driving force.

[0062] In the embodiments of the present disclosure, controlling the operation of the third motor 29 can drive the third spur gear 30 to rotate. Through the meshing action between the teeth and the third straight teeth, the fifth cylindrical member 27 can be driven to rotate. Then, under the pulling or pushing of a plurality of connecting rods 28, and the guiding and supporting actions of a plurality of guide rails 22 and a plurality of sliders 23, a plurality of support frames 24 reciprocate in the radial direction of the processing cylinder 1 in the opposite direction. Therefore, by controlling the forward and reverse rotation of a single third motor 29, the function of the plurality of rows of hollow shafts 5 and the plurality of rows of rotating shafts 6 around the circumference to reciprocate in the radial direction of the processing cylinder 1 can be finally realized. The number of power sources is reduced, complex electrical interlock control is not required, and the failure risk is reduced.

[0063] Optionally, in combination with Figure 1 、 Figure 7 and Figure 8 shown, a ninth bearing is further included. The ninth bearing is installed between the fourth cylindrical member 26 and the fifth cylindrical member 27.

[0064] In the embodiments of the present disclosure, the ninth bearing is used to reduce the friction force between the fourth cylindrical member 26 and the fifth cylindrical member 27, and improve the accuracy when the fifth cylindrical member 27 rotates relative to the fourth cylindrical member 26.

[0065] Optionally, in combination with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the spraying member further includes a cylindrical seat 31 and a nozzle 32. The cylindrical seats 31 are respectively installed on multiple columns of hollow shafts 5 around, and are coaxially distributed with multiple columns of hollow shafts 5 around. The interiors of multiple columns of cylindrical seats 31 around are respectively communicated with multiple columns of hollow shafts 5 around, so that solutions such as urea or ammonia water can enter the temporal parts of multiple columns of cylindrical seats 31 around through multiple columns of hollow shafts 5 around respectively. The nozzles 32 are respectively installed on the sides of multiple columns of cylindrical seats 31 around, and are evenly distributed around multiple columns of cylindrical seats 31 around. A plurality of nozzles 32 on each cylindrical seat 31 are respectively communicated with its interior, so that solutions such as urea or ammonia water in multiple columns of cylindrical seats 31 around can be sprayed out from a plurality of nozzles 32 thereon.

[0066] In the embodiment of the present disclosure, since a plurality of nozzles 32 on each cylindrical seat 31 are located on its annular side surface, the spraying directions of the plurality of nozzles 32 are different from each other, thereby increasing the spraying range at the initial spraying. Then, under the drive of the driving member, after the plurality of nozzles 32 revolve, rotate and move, a movable spherical spraying area can be formed. Moreover, multiple rows of spraying members around jointly perform spraying operations, and spherical spraying areas that can intersect, separate or overlap with each other can be formed inside the treatment cylinder 1, so that solutions such as urea or ammonia water are evenly dispersed inside the treatment cylinder 1, thereby further improving the mixing effect with the flue gas.

[0067] Optionally, in combination with Figures 1 to 4 As shown, the mixing member further includes straight blades 33 and L-shaped blades 34. The straight blades 33 are respectively connected to multiple columns of rotating shafts 6 around, and are evenly distributed around each rotating shaft 6, and are used for agitating the flue gas and water vapor.

[0068] In the embodiment of the present disclosure, after any rotating shaft 6 is controlled to rotate, it can drive a plurality of straight blades 33 and L-shaped blades 34 thereon to rotate, and finally agitate the flue gas and water vapor to improve the mixing effect. At the same time, affected by the blade shape, the straight blades 33 can push the flue gas and water vapor to flow along the axial direction of the rotating shaft 6, while the L-shaped blades 34 can push the flue gas and water vapor to flow along the radial direction of the rotating shaft 6, thereby forming a divergent flow path. Then, under the drive of the driving member, after multiple mixing members revolve, rotate and move, the flow paths can intersect, separate or overlap with each other, further improving the mixing effect of the flue gas and water vapor.

[0069] Optionally, in combination with Figures 1 to 4As shown in the figure, the transmission components include the first transmission shaft 35, the fourth spur gear, the second transmission shaft 36, the fifth spur gear, the third bevel gear, and the fourth bevel gear. The first transmission shaft 35 is respectively rotatably installed on the side walls of the boxes 4 in multiple columns around, and is adjacent to the hollow shafts 5 in multiple columns around. It can respectively rotate relative to the boxes 4 in multiple columns around. The fourth spur gears are respectively installed on the hollow shafts 5 in multiple columns around and the first transmission shafts 35 in multiple columns around. Two adjacent fourth spur gears are meshed with each other to jointly transmit the driving force, so that the hollow shafts 5 in multiple columns around can rotate with the rotation of the first transmission shafts 35 in multiple columns around. The second transmission shaft 36 is respectively rotatably installed on the side walls of the boxes 4 in multiple columns around, and is adjacent to the rotating shafts 6 in multiple columns around.

The third bevel gears are respectively installed on the first transmission shafts 35 in multiple columns around and the second transmission shafts 36 in multiple columns around, and are respectively used to drive the first transmission shafts 35 in multiple columns around and the second transmission shafts 36 in multiple columns around to rotate. The fourth bevel gears are respectively installed on the second hollow spline shafts 7 in multiple columns around, and rotate respectively driven by the second hollow spline shafts 7 in multiple columns around. The fourth bevel gears in multiple columns around are respectively meshed with the third bevel gears in multiple columns around to jointly transmit the driving force and change the direction of the acting force.

[0070] In the embodiment of the present disclosure, after the second hollow spline shafts 7 in multiple columns around are controlled to rotate, the fourth bevel gears in multiple columns around can be driven to rotate. Through the meshing action between teeth, the third bevel gears in multiple columns around can be driven to rotate, and then the first transmission shafts 35 in multiple columns around and the second transmission shafts 36 in multiple columns around can be driven to rotate. Then, under the meshing action between teeth of the fourth spur gears in multiple columns around and the fifth bevel gears in multiple columns around, the hollow shafts 5 in multiple columns around and the rotating shafts 6 in multiple columns around can rotate. Finally, the function that the hollow shafts 5 in multiple columns around and the rotating shafts 6 in multiple columns around rotate with the rotation of the second hollow spline shafts 7 in multiple columns around is realized.

The second circular pipes 38 are respectively installed on multiple columns of support bases 37 around, and are respectively opposite to multiple columns of second hollow spline shafts 7 around, and are respectively used to convey solutions such as urea or ammonia water. The second rotary joints are respectively installed between multiple columns of second hollow spline shafts 7 and multiple columns of second circular pipes 38 around, and are used to enable mutual rotation between multiple columns of second hollow spline shafts 7 and multiple columns of second circular pipes 38 around. The right-angle rotary joints are respectively installed between multiple columns of the hollow shafts 5 and multiple columns of the second circular pipes 38 around, and are used to enable mutual rotation between multiple columns of the hollow shafts 5 and multiple columns of the second circular pipes 38 around.

[0072] In the embodiments of the present disclosure, the second circular pipe 38, the second rotary joint and the right-angle rotary joint are all used to convey solutions. At the same time, the second rotary joint is used to enable mutual rotation between multiple columns of second hollow spline shafts 7 and multiple columns of second circular pipes 38 around, and the right-angle rotary joint is used to enable mutual rotation between multiple columns of the hollow shafts 5 and multiple columns of the second circular pipes 38 around, so that mutual rotation can be achieved between multiple columns of two mutually perpendicular pipelines while conveying media.
