Description

Technical Field

[0001] The present application relates to the technical field of fly ash solidification, and in particular to a fly ash chelating solidification mixer. Background Art

[0002] With the rapid development of economy and the rapid improvement of people's living standards, the amount of urban solid waste in my country has increased dramatically. In the process of solid waste disposal, there are two main methods: landfill disposal and incineration disposal. Due to the influence of various environmental factors during landfill disposal, centralized incineration has gradually become the main method of urban domestic waste disposal in my country. A large amount of fly ash will be generated during the incineration process of solid waste. The incineration fly ash contains heavy metals such as lead, cadmium, and mercury with high leaching concentrations. If these harmful heavy metal substances are not effectively treated, they will re-enter the environment, pollute groundwater sources and endanger humans. Therefore, before the final disposal of the incineration fly ash, it must be stabilized and solidified. Usually, a fly ash mixer is used to add a chelating agent to solidify the incineration fly ash.

[0003] Regarding the above-mentioned related technologies, there are the following defects: in the prior art, a ton bag is placed under the discharge pipe of the mixer to receive the chelate. The chelate is prone to dust generation during the discharge and bagging process, resulting in dust in the fly ash treatment workshop. The working environment is extremely harsh, which is very harmful to the health of the workers. Therefore, further improvement is needed. Summary of the invention

[0004] In order to reduce the possibility of dust spillage during the unloading and bagging process of the chelate, improve the working environment of the fly ash treatment workshop, and ensure the health of production personnel, the present application provides a fly ash chelating and solidification mixer.

[0005] The fly ash chelation solidification mixer provided in this application adopts the following technical solution:

[0006] A fly ash chelating and solidification mixer, comprising a supporting frame, a mixer body and a material receiving device, the mixer body is arranged on the supporting frame, a feeding pipe is arranged at the lower part of the mixer body, the feeding pipe is penetrated by a connecting seat, the connecting seat is provided with a plurality of connecting blocks distributed around the axis of the feeding pipe, the connecting block is provided with a hanging arm, the material receiving device comprises a material receiving ton bag, the outer side wall of the bag opening of the material receiving ton bag is fixedly connected with a plurality of hanging ring belts, the hanging ring belts are hung on the hanging arm, the lower part of the feeding pipe is inserted into the material receiving ton bag at the bag opening of the material receiving ton bag, the connecting block is provided with a connecting arm, the connecting arm is connected with a clamping plate for sliding along the radial direction of the feeding pipe, the clamping plate is located below the hanging arm, the side of the clamping plate close to the feeding pipe is an arc surface adapted to the outer side wall of the feeding pipe, and the connecting arm is provided with a clamping driving member for driving the clamping plate to slide.

[0007] By adopting the above technical scheme, before unloading the chelate, the staff will open the bag mouth of the receiving ton bag, and after the bag wall of the receiving ton bag passes through the gap between the outer wall of the unloading pipe and the clamping plate, the hanging ring belt on the receiving ton bag is hung on the hanging arm, so that the receiving ton bag is sleeved on the unloading pipe; the clamping drive drives the clamping plate to slide in the direction close to the unloading pipe, and the upper peripheral bag wall of the receiving ton bag is simultaneously driven to move in the direction close to the unloading pipe and abut against the outer peripheral wall of the unloading pipe during the sliding process of multiple clamping plates, and then the unloading operation is carried out, thereby reducing the possibility of a gap between the inner wall of the bag mouth of the receiving ton bag and the unloading pipe, thereby reducing the possibility of the chelate overflowing from the bag mouth of the receiving ton bag after dust is generated during the unloading and bagging process. The receiving ton bag is first suspended by the hanging arm, and there is no need for manual support of the receiving ton bag, which effectively reduces the labor intensity of the staff, and then the receiving ton bag is clamped and fixed by the clamping drive to improve operational safety.

[0008] Preferably, the clamping drive member comprises a clamping cylinder, a cylinder body of the clamping cylinder is fixedly connected to the connecting arm, and the clamping plate is fixedly connected to the piston rod of the clamping cylinder.

[0009] By adopting the above technical solution, the reciprocating sliding motion of the clamping plate is achieved by extending and retracting the piston rod of the clamping cylinder, the clamping cylinder has a fast response speed, and the work efficiency is improved.

[0010] Preferably, the material receiving device also includes a material receiving platform located below the receiving ton bag, the connecting block is connected to the connecting seat along the radial sliding direction of the discharge pipe, and the connecting seat is provided with a first elastic member that forces the connecting block to slide in the direction away from the discharge pipe. Under normal circumstances, when the connecting block is located in the initial position and the piston rod of the clamping cylinder is extended to the maximum stroke, there is an installation gap between the clamping plate and the discharge pipe for the bag wall of the receiving ton bag to pass through, and the hanging ring belt on the receiving ton bag is hung on the hanging arm, and the bottom of the receiving ton bag is suspended on the material receiving platform.

[0011] By adopting the above technical scheme, in the initial state, the first elastic member forces the connecting block to slide toward the outside of the connecting seat, and the piston rod of the clamping cylinder is in an extended state. Before the material is discharged from the discharge pipe, the staff will open the bag mouth of the receiving ton bag, and after the bag wall of the receiving ton bag passes through the gap between the outer wall of the discharge pipe and the clamping plate, the hanging ring belt on the receiving ton bag is hung on the hanging arm, so that the receiving ton bag is sleeved on the discharge pipe and the receiving ton bag is suspended on the receiving platform, and then the material discharge operation is carried out. When the chelated material begins to be filled in the receiving ton bag, the receiving ton bag drops to the bottom due to its own weight and abuts against the upper end surface of the receiving platform. The receiving platform supports the receiving ton bag, and the receiving ton bag is suspended by the hanging ring belt during the descent process. The connecting block drives the connecting arm to slide synchronously, thereby driving the clamping plate to slide toward the axis of the discharge pipe and abut against the outer wall of the discharge pipe to clamp and seal the bag mouth of the receiving ton bag, thereby reducing the possibility of a gap between the inner wall of the bag mouth of the receiving ton bag and the discharge pipe, thereby reducing the possibility of the chelate overflowing from the bag mouth of the receiving ton bag after dust is generated during the discharge and bagging process. With this arrangement, the clamping plate will clamp and seal the bag mouth of the receiving ton bag only when bagging is started, thereby reducing the possibility of the staff's hands being pinched by the clamping plate when installing the receiving ton bag on the discharge pipe, thereby improving operational safety.

[0012] Preferably, the connecting seat is coaxially rotatably connected to the feeding pipe, and the supporting frame is provided with a driving mechanism for driving the connecting seat to rotate around its own axis.

[0013] By adopting the above technical scheme, after the bagging of the receiving material ton bag is completed, the piston rod of the clamping cylinder contracts, driving the clamping plate to slide and reset in the direction away from the axis of the discharge pipe, and then the connecting seat is driven by the driving mechanism to rotate around its own axis, and the connecting seat drives the connecting block, the connecting arm and the hanging arm to rotate. The receiving material ton bag after bagging does not rotate due to its own weight. The rotation of the hanging arm drives the upper bag wall of the receiving material ton bag to spirally wrap through the hanging ring belt, and after the bag mouth of the receiving material ton bag is sealed, the hanging ring belt is removed from the hanging arm, thereby reducing the possibility of dust overflowing from the bag mouth of the receiving material ton bag during the unloading process.

[0014] Preferably, the driving mechanism includes a transmission gear ring coaxially fixedly sleeved on the outer peripheral wall of the connecting seat, a driving motor fixedly connected to the supporting frame, and a driving gear coaxially fixedly connected to the output shaft of the driving motor, and the driving gear is externally meshed with the transmission gear ring.

[0015] By adopting the above technical solution, when it is necessary to wrap and seal the bag mouth of the docking material ton bag, the driving motor is started to drive the active gear to rotate, and the connecting seat is driven to rotate through the transmission gear ring.

[0016] Preferably, the lower end of the hanging arm is inclined toward the side close to the discharge pipe, and the upper surface of the lower end of the hanging arm is fixedly connected to a limiting plate, and a V-shaped groove is formed at the connection between the limiting plate and the hanging arm for hanging the hanging ring belt, and the hanging arm is slidably connected to a sliding plate along the length direction, and the end of the sliding plate away from the hanging arm is fixedly connected to an anti-slip plate abutting against the end of the limiting plate away from the hanging arm, and the hanging arm is provided with a second elastic member that forces the sliding plate to slide toward the limiting plate under normal conditions so that the anti-slip plate abuts against the limiting plate.

[0017] When the bag is to be removed from the hanging arm, a force is applied to the sliding plate again to make the sliding plate slide in the direction away from the limiting plate, thereby providing a gap between the anti-slip plate and the limiting plate for the hanging band to pass through. At this time, the second elastic member has elastic potential energy. After the hanging band passes through the gap, the force applied to the sliding plate is removed, and the second elastic member forces the sliding plate to slide back to its original position, so that the anti-slip plate abuts against the limiting plate again, effectively reducing the possibility of the hanging band slipping out of the hanging arm when the bag is wrapped and sealed, thereby improving the smoothness of the bag wrapping and sealing work. When the hanging band needs to be removed from the hanging arm, a force is applied to the sliding plate again to make the sliding plate slide in the direction away from the limiting plate, and then the hanging band is slid and taken out from the gap between the anti-slip plate and the limiting plate, thereby improving the convenience of removing the hanging band.

[0018] Preferably, the hanging arm is fixedly connected to a fixed plate, the sliding plate is located between the fixed plate and the limiting plate, the second elastic member is fixedly connected between the sliding plate and the fixed plate, a rope threading hole is provided at one end of the hanging arm away from the limiting plate, the fixed plate is located between the sliding plate and the rope threading hole, the sliding plate is fixedly connected to a linkage rope, and the other end of the linkage rope is passed through the rope threading hole and fixedly connected to the clamping plate.

[0019] After wrapping and sealing, the piston rod of the clamping cylinder is extended and reset, and the gap between the anti-slip plate and the limiting plate is opened, and the staff can directly slide the suspension belt along the limiting plate to take it out, thereby reducing the operation steps and improving the convenience of unloading the suspension belt.

[0020] Preferably, the lower part of the mixer body is conically arranged to form a frustum, the feed pipe is coaxially fixedly connected to the lower end of the frustum, the feed pipe is provided with a flow control valve, and the feed pipe is provided with a vibration mechanism for beating the outer wall of the frustum of the mixer body.

[0021] By adopting the above technical scheme, the lower part of the mixer body is set in a cone shape, which is convenient for the chelate in the mixer body to slide through the inner wall of the cone and fall into the discharge pipe. After each discharge of the discharge pipe is completed, the flow control valve closes the discharge pipe. Before the next ton bag bagging operation is required, the outer wall of the frustum part of the mixer body is beaten by the vibration mechanism to perform a vibration operation, so that the chelate accumulated on the inner wall of the frustum part of the mixer body can slide smoothly and fall into the discharge pipe, thereby reducing the possibility of material accumulation in the lower part of the mixer body.

[0022] Preferably, the vibration mechanism includes a mounting plate coaxially fixedly sleeved on the discharge pipe and a beating rod vertically slidably penetrated through the mounting plate, the upper end surface of the connecting seat is fixedly connected with an active gear ring, the active gear ring is formed by continuous wavy tooth grooves and tooth protrusions, the lower end of the beating rod is provided with a ball head adapted to the tooth grooves on the active gear ring, the mounting plate is provided with a third elastic member for forcing the beating rod to slide downward so that the ball head always abuts against the tooth grooves or tooth protrusions on the active gear ring, when the ball head abuts against the tooth protrusions on the active gear ring, the upper part of the beating rod abuts against the outer wall of the conical portion of the mixer body.

[0023] By adopting the above technical scheme, the driving mechanism drives the connecting seat to rotate to wrap and seal the bag mouth of the docking material ton bag. During the process, the ball head at the lower part of the beating rod is always in contact with the upper surface of the active gear ring by the force of the third elastic member. When the ball head is in contact with the tooth convex position of the active gear ring, the beating rod slides upward. At this time, the third elastic member undergoes elastic deformation and has elastic potential energy. The connecting seat drives the active gear ring to rotate together so that when the ball head reaches the next tooth groove, the third elastic member elastically resets and drives the beating rod to slide downward, thereby realizing the up and down reciprocating sliding motion of the beating rod to realize the repeated beating operation on the outer wall of the frustum part of the mixer body. It has linkage, does not need to add additional driving parts, reduces the programming difficulty of the control program, and reduces the maintenance cost of the equipment.

[0024] Preferably, the beating rods are provided in plurality and distributed around the axis of the discharge pipe.

[0025] By adopting the above technical solution, a plurality of beating rods are provided to synchronously beat different positions of the outer side wall of the frustum portion of the mixer body, thereby improving the vibration effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. First, the docking material ton bag is suspended by the hanging arm, and no manual support is required for the docking material ton bag, which effectively reduces the labor intensity of the staff. Then, the docking material ton bag is clamped and fixed by the clamping driving member to improve the operation safety. The clamping driving member drives the clamping plate to slide toward the direction of the discharge pipe. During the sliding process of multiple clamping plates, the upper peripheral bag wall of the docking material ton bag is simultaneously driven to move toward the direction of the discharge pipe and abut against the outer peripheral wall of the discharge pipe before the discharge operation is carried out, thereby reducing the possibility of a gap between the inner wall of the bag opening of the docking material ton bag and the discharge pipe, thereby reducing the possibility of the chelate compound overflowing from the bag opening of the docking material ton bag after dust is generated during the discharge and bagging process;

[0028] 2. The clamping plate will clamp and seal the mouth of the bulk bag only when the bagging is started, which reduces the possibility of the worker's hands being injured by the clamping plate when installing the bulk bag on the feeding pipe, thus improving the safety of operation;

[0029] 3. After the bagging of the receiving ton bag is completed, the piston rod of the clamping cylinder contracts, driving the clamping plate to slide and reset in the direction away from the axis of the discharge pipe, and then the connecting seat is driven by the driving mechanism to rotate around its own axis. The connecting seat drives the connecting block, the connecting arm and the hanging arm to rotate. The receiving ton bag after bagging does not rotate due to its own weight. The rotation of the hanging arm drives the upper bag wall of the receiving ton bag to spirally wrap through the hanging ring belt, and then the bag mouth of the receiving ton bag is sealed, and then the hanging ring belt is removed from the hanging arm, thereby reducing the possibility of dust overflowing from the bag mouth of the receiving ton bag during the unloading process.

The material receiving device 3 includes a material receiving platform 31 located below the mixer body 2 and a material receiving ton bag 32 arranged between the material receiving platform 31 and the mixer body 2 for filling the chelate. In this embodiment, the material receiving platform 31 is a lifting platform with a lifting and lifting function. A guide rail is fixed on the ground surface, and the material receiving platform 31 moves on the guide rail through roller sliding to realize the transfer operation of the material receiving ton bag 32 after loading.

[0039] Reference Figure 1 , Figure 2 The upper part of the mixer body 2 is provided with a plurality of hoppers 21, which are used to add materials such as fly ash, chelating agent and cement respectively. The mixer body 2 is provided with a stirring device for mixing and stirring the materials. The stirring device is a prior art and will not be described in detail here. The lower part of the mixer body 2 is conically arranged to form a frustum part 22. The lower part of the mixer body 2 is coaxially fixedly connected with a feed pipe 23. The feed pipe 23 is coaxially fixedly connected to the lower end of the frustum part 22. The feed pipe 23 is provided with a flow control valve (not shown in the figure) for controlling the start and stop of the feed operation. Specifically, the flow control valve is a solenoid valve.

[0040] The feed tube 23 is coaxially rotatably connected to the connection seat 4, wherein a crossbeam 13 is fixedly connected between the two support columns 12, and the crossbeam 13 is provided with a driving mechanism 14 for driving the connection seat 4 to rotate around its own axis.

[0041] Reference Figure 2 , Figure 3 The feeding tube 23 is provided with a vibration mechanism 5 for beating the outer wall of the frustum portion 22 of the mixer body 2.

The mounting plate 51 is located above the connecting seat 4. The beating rod 52 is provided with a plurality of beating rods distributed around the axis of the feeding tube 23. The beating rod 52 is coaxially fixedly sleeved with a limit ring 53 located above the mounting plate 51. A third elastic member 54 forcing the beating rod 52 to slide downward is provided between the limit ring 53 and the mounting plate 51.

One end of the third spring is fixedly connected to the lower end face of the limit ring 53, and the other end of the third spring is fixedly connected to the upper end face of the mounting plate 51.

[0042] The upper end surface of the connecting seat 4 is coaxially fixedly connected with an active gear ring 41, which is formed by continuous wavy tooth grooves and tooth protrusions. The lower end of the beating rod 52 is fixedly connected with a ball head 55 located below the mounting plate 51 and adapted to the tooth grooves on the active gear ring 41. The beating rod 52 is subjected to the action of the third spring so that the ball head 55 always abuts against the tooth grooves or tooth protrusions on the active gear ring 41. When the ball head 55 abuts against the tooth protrusions on the active gear ring 41, the third spring is compressed and has elastic potential energy, and the upper part of the beating rod 52 abuts against the outer wall of the frustum part 22 of the mixer body 2. When the connecting seat 4 drives the active gear ring 41 to rotate together so that the ball head 55 reaches the next tooth groove, the third spring elastically resets and drives the beating rod 52 to slide downward. When the connecting seat 4 rotates continuously, the beating rod 52 realizes the up and down reciprocating sliding motion to realize the repeated beating operation on the outer wall of the frustum part 22 of the mixer body 2.

[0043] The lower end surface of the connection seat 4 is provided with a plurality of connection blocks 42 distributed around the axis of the discharge pipe 23. In this embodiment, four connection blocks 42 are provided, and the connection blocks 42 are connected to the lower end surface of the connection seat 4 by sliding along the radial direction of the discharge pipe 23. The connection seat 4 is provided with a first elastic member 44 that forces the connection block 42 to slide away from the discharge pipe 23 under normal conditions. The outer edge of the lower end surface of the connection seat 4 is fixedly connected with a connection plate 43. The first elastic member 44 is a first spring located between the connection block 42 and the connection plate 43. One end of the first spring is fixedly connected to the connection block 42, and the other end of the first spring is fixedly connected to the connection plate 43.

The lower end of the hanging arm 45 is inclined toward the side close to the feeding pipe 23. The upper surface of the lower end of the hanging arm 45 is fixedly connected with a limiting plate 451, so that a V-shaped groove is formed at the connection between the limiting plate 451 and the hanging arm 45. The outer side wall of the bag opening of the receiving ton bag 32 is fixedly connected with a plurality of hanging ring belts 33 (refer to Figure 6 ), the number of the hanging ring belts 33 corresponds to the number of the hanging arms 45 and the connecting arms 46, and the hanging ring belts 33 are hung in the V-shaped slots. The upper end surface of the hanging arm 45 is connected to a sliding plate 452 for sliding along the length direction, and the plate surface of the sliding plate 452 is perpendicular to the length direction of the hanging arm 45. The side wall of the upper part of the sliding plate 452 close to the limit plate 451 is fixedly connected to an anti-slip plate 453, and the anti-slip plate 453 abuts against the upper part of the limit plate 451. The hanging arm 45 is provided with a second elastic member 455 for forcing the sliding plate 452 to slide toward the limit plate 451 under normal conditions so that the anti-slip plate 453 abuts against the limit plate 451. The upper end surface of the hanging arm 45 is fixedly connected to a fixed plate 454, the sliding plate 452 is located between the fixed plate 454 and the limiting plate 451, the second elastic member 455 is a second spring located between the sliding plate 452 and the fixed plate 454, one end of the second spring is fixedly connected to the sliding plate 452, and the other end of the second spring is fixedly connected to the fixed plate 454.

[0045] Reference Figure 4 , Figure 5The connecting arm 46 is connected with a clamping plate 461 in a radially sliding manner along the material discharge pipe 23. The clamping plate 461 is located below the hanging arm 45. The side of the clamping plate 461 close to the material discharge pipe 23 is an arc surface adapted to the outer wall of the material discharge pipe 23. The connecting arm 46 is provided with a clamping driving member that drives the clamping plate 461 to slide so as to abut the bag wall of the receiving material ton bag 32 against the outer peripheral wall of the material discharge pipe 23. The clamping driving member is a clamping cylinder 462. The cylinder body of the clamping cylinder 462 is fixedly connected to the connecting arm 46. The piston rod of the clamping cylinder 462 is slidably arranged in the connecting arm 46. The clamping plate 461 is fixedly connected to the piston rod of the clamping cylinder 462. A rope hole is formed at one end of the hanging arm 45 away from the limiting plate 451 , and the fixing plate 454 is located between the sliding plate 452 and the rope hole. The sliding plate 452 is fixedly connected with a linkage rope 456 , and the other end of the linkage rope 456 passes through the rope hole and is fixedly connected to the clamping plate 461 .

[0046] Under normal circumstances, the lifting platform is at the lowest position, the piston rod of the clamping cylinder 462 is extended to the maximum stroke, and the sliding plate 452 is pulled by the linkage rope 456 to slide away from the limit plate 451, so that there is a gap between the anti-slip plate 453 and the limit plate 451 for hanging the suspension ring belt 33, and the second spring is compressed and has elastic potential energy; the connecting block 42 is located at a side position of the connecting seat 4 close to the connecting plate 43, and when the piston rod of the clamping cylinder 462 is extended to the maximum stroke, there is still an installation gap between the clamping plate 461 and the discharge pipe 23 for the bag wall of the receiving ton bag 32 to pass through, the suspension ring belt 33 on the empty receiving ton bag 32 is hung behind the V-shaped groove, and the bottom of the empty receiving ton bag 32 is suspended above the receiving platform 31.

[0047] The implementation principle of the fly ash chelation solidification mixer of the embodiment of the present application is as follows: the staff opens the bag mouth of the receiving ton bag 32, and after the bag wall of the receiving ton bag 32 passes through the gap between the outer wall of the discharge pipe 23 and the clamping plate 461, the hanging ring belt 33 on the receiving ton bag 32 is sleeved on the limit plate 451 and hung on the V-shaped groove, so that the discharge pipe 23 is inserted at the bag mouth of the receiving ton bag 32, and the empty receiving ton bag 32 is suspended on the receiving platform 31;

[0048] Then, the flow control valve is opened to carry out the unloading operation. When the chelated material begins to be filled in the receiving ton bag 32, the receiving ton bag 32 drops due to gravity until the bag bottom of the receiving ton bag 32 abuts against the upper end surface of the receiving platform 31. The receiving platform 31 supports the receiving ton bag 32. During the descent of the receiving ton bag 32, the hanging ring belt 33 pulls the hanging arm 45 and the connecting block 42 to slide toward the direction of the unloading pipe 23. The connecting block 42 drives the connecting arm 46 to slide synchronously, so that the clamping plate 461 slides toward the axis direction of the unloading pipe 23 and abuts against the outer peripheral wall of the unloading pipe 23, clamps and seals the bag mouth of the receiving ton bag 32, reduces the possibility of a gap between the bag mouth inner wall of the receiving ton bag 32 and the unloading pipe 23, and thus reduces the possibility of the chelate overflowing from the bag mouth of the receiving ton bag 32 after dust is generated during the unloading and bagging process.

[0049] After the material is unloaded, the flow control valve is closed, and the piston rod of the clamping cylinder 462 is contracted, driving the clamping plate 461 to slide in the direction away from the axis of the unloading pipe 23, and then the clamping effect of the clamping plate 461 on the bag wall of the docking material ton bag 32 is removed. At the same time, the second spring elastic reset forces the sliding plate 452 to slide and reset, so that the anti-slip plate 453 abuts against the limit plate 451, preventing the suspension ring belt 33 from sliding out of the limit plate 451; start the drive motor 141 to drive the connecting seat 4 to rotate, and the connecting seat 4 belt The movable connecting block 42, the connecting arm 46 and the hanging arm 45 rotate, and the receiving ton bag 32 after bagging does not rotate due to its own weight. The hanging arm 45 rotates to drive the upper bag wall of the receiving ton bag 32 to perform spiral wrapping operation through the hanging ring belt 33. During the rotation of the connecting seat 4, the hammer rod 52 is reciprocated up and down through the active gear ring 41, thereby realizing the hammering and vibration operation on the outer side wall of the frustum part 22 of the mixer body 2, thereby reducing the possibility of material accumulation at the lower part of the mixer body 2.

[0050] After wrapping and sealing the bag mouth of the docking material ton bag 32, the staff ties the docking material ton bag 32 with a cable tie, applies a force to the sliding plate 452 to make the sliding plate 452 slide away from the limit plate 451, and then removes the hanging ring belt 33 from the hanging arm 45, and finally transfers it through the receiving platform 31.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
