Description

Technical Field

[0001] This invention belongs to the field of industrial production technology, specifically a light ash calcination furnace treatment device that is easy to clean. Background Technology

[0002] Currently, in the production and processing of light ash, it is necessary to use a calcining furnace to calcine the light ash raw materials to obtain light ash. During the calcination process, the light ash will continuously adhere to the inner wall of the calcining furnace. Over time, this will not only affect the output of light ash, but also lead to the calcination effect of the subsequent light ash raw materials. Therefore, it is necessary to clean the light ash on the inner wall of the calcining furnace regularly.

[0003] In existing technologies, when cleaning the light ash on the inner wall of a calcining furnace, most methods involve using a scraping mechanism to extend into the furnace to scrape off the light ash adhering to the inner wall, or spraying high-pressure air into the furnace to blow the light ash away. However, regardless of the cleaning method, the light ash will escape from the inlet and outlet of the calcining furnace, thus polluting the surrounding environment. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a light ash calcining furnace treatment device that is easy to clean.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A light ash calcining furnace treatment device that is easy to clean includes a riser pipe, a gas supply assembly, a core rod, an air bladder, a limiting assembly, and a collection assembly. The gas supply component is located inside the riser pipe. The upper end of the core rod extends from the bottom of the lifting tube into the interior of the lifting tube and is connected to the air supply assembly, while the lower end extends below the lifting tube and is connected to the limiting assembly. The airbag is mounted on the outer wall of the lifting tube. As the riser tube moves upward relative to the core rod, the air supply assembly compresses the air inside the riser tube into the air bladder, causing the air bladder to inflate. The inflated air bladder acts on the inner wall of the furnace and moves upward along the inner wall of the furnace with the riser tube to clean the light ash on the inner wall of the furnace. The collection component is installed on the outer wall of the lifting pipe and is used to collect the light dust that is cleared down by the airbag.

[0006] As a further improvement of the present invention: the air supply assembly includes an air supply piston, which is movably disposed inside the lifting tube, and the upper end of the core rod extends from the bottom of the lifting tube into the interior of the lifting tube and is fixedly connected to the bottom wall of the air supply piston.

[0007] As a further improvement of the present invention: a first air supply hole is provided on the lower part of the side wall of the lifting pipe. The collection component includes a collection ring block. The collecting ring block is fixedly installed on the outer wall of the lifting pipe. The collecting ring block has several collecting grooves, which vertically penetrate the collecting ring block. Each set of collecting grooves has a mesh at the bottom of its inner side. The collecting ring block has a third air passage inside. The airbag is located on the outside of the collecting ring block. One end of the third air passage is connected to the first air supply hole, and the other end is connected to the inner cavity of the airbag. The airbag has a V-shaped fold, and several second air supply holes are opened in the V-shaped fold.

[0008] As a further improvement of the present invention: a sealing cover that cooperates with the feed inlet is movably sleeved on the outside of the lifting pipe, and a locking bolt is provided on the sealing cover.

[0009] As a further improvement of the present invention: the airbag has a ring-shaped structure, the upper end of the airbag is connected to the upper surface of the collecting ring block, and the lower end of the airbag is connected to the annular outer wall of the collecting ring block. An elastic support component is also provided on the upper part of the collecting ring block in the inner area of ​​the airbag. When the airbag moves to the top position inside the furnace body, the elastic support component is used to provide elastic support force to the airbag in the direction of the lifting pipe, thereby driving the airbag to contract and causing the upper end of the airbag to stick to the outer wall of the lifting pipe.

[0010] As a further improvement of the present invention: an exhaust hole is provided on the upper part of the side wall of the lifting pipe, a first air passage is provided on the side wall of the air supply piston, and a second air passage is provided on the upper part of the air supply piston, the second air passage being connected to the first air passage. The elastic support assembly includes a pressure plate and a third elastic element. The pressure plate is provided in several groups, and several pressure plates are hinged to the upper part of the collection ring block. Several pressure plates are distributed in a ring at intervals on the upper part of the collection ring block. Several pressure plates are attached to the inner wall of the airbag. Each group of pressure plates is connected to the collection ring block on one side through a group of third elastic members. The third elastic members are used to provide elastic support for the pressure plate.

[0011] As a further improvement of the present invention: the limiting component includes a limiting rod, a turntable, and a second elastic element. The limiting rods are provided in several groups, and several limiting rods are hinged at the bottom of the side wall of the core rod. The upper part of each group of limiting rods is connected to the outer wall of the core rod through a set of second elastic members. The second elastic members are used to provide elastic support for the limiting rods. The turntable is rotatably disposed at the bottom of the core rod, and several slots corresponding to the limiting rods are opened on the turntable.

[0012] As a further improvement of the present invention: the upper end of the air supply piston is connected to the inner top wall of the lifting tube through a first elastic element. The first elastic element is used to provide elastic tension to the air supply piston. An air inlet pipe is provided at the bottom of the lifting tube, and a one-way valve is provided inside the air inlet pipe.

[0013] As a further improvement of the present invention: the first elastic element, the second elastic element and the third elastic element are springs or metal sheets.

[0014] As a further improvement of the present invention: the mesh can be detachably installed at the bottom of the inner side of the collection tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, when it is necessary to clean the light ash on the inner wall of the furnace, a lifting mechanism can be used to move the lifting pipe, core rod, air bag, limiting component, and collecting component downwards as a whole. As the lifting pipe, core rod, air bag, limiting component, and collecting component move downwards, they enter the furnace body through the feed inlet at the top. After entering the furnace body, the limiting component extends out from the discharge outlet at the bottom and acts on the end of the discharge outlet, thus limiting the core rod. At this time, the air bag and collecting component remain at the bottom of the inner side of the furnace body. Then, the lifting mechanism moves the lifting pipe upwards relative to the core rod, and the air supply unit... The device compresses air from inside the lifting pipe into the airbag, causing it to inflate. Once inflated, the airbag contacts the inner wall of the furnace. The airbag and the collection assembly move upwards synchronously with the lifting pipe. As the airbag moves upwards, it cleans the light ash on the inner wall of the furnace. The light ash cleaned by the airbag is collected by the collection assembly, thus preventing light ash from filling the furnace cavity. Compared with existing technologies, this device can automatically clean the light ash on the inner wall of the furnace and collect the cleaned light ash, thereby preventing light ash from escaping into the surrounding environment and achieving effective protection of the surrounding environment.

Therefore, they should not be construed as limitations on this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Please see Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a light ash calcining furnace treatment device that is easy to clean, including a lifting pipe 10, a gas supply component 20, a core rod 30, an air bag 40, a limiting component 50, and a collecting component 60. The gas supply component 20 is disposed inside the lifting pipe 10. The upper end of the core rod 30 extends from the bottom of the lifting pipe 10 into the interior of the lifting pipe 10 and is connected to the gas supply component 20, and the lower end extends below the lifting pipe 10 and is connected to the limiting component 50. The air bag 40 is disposed in the lifting pipe 10. On the outer wall, when the lifting pipe 10 moves upward relative to the core rod 30, the air supply component 20 pressurizes the air inside the lifting pipe 10 into the air bag 40 to drive the air bag 40 to expand. The expanded air bag 40 acts on the inner wall of the furnace body 80 and moves upward along the inner wall of the furnace body 80 with the lifting pipe 10 to clean the light ash on the inner wall of the furnace body 80. The collection component 60 is installed on the outer wall of the lifting pipe 10 to collect the light ash cleaned down by the air bag 40.

[0022] When cleaning of light ash on the inner wall of furnace body 80 is required, a lifting mechanism (not shown in the figure) can be used to move the lifting pipe 10, core rod 30, air bag 40, limiting component 50, and collecting component 60 downwards as a whole. As the lifting pipe 10, core rod 30, air bag 40, limiting component 50, and collecting component 60 move downwards, they enter the furnace body 80 through the feed inlet 801 at the upper end of the furnace body 80. After entering the furnace body 80, the limiting component 50 extends out from the discharge outlet 802 at the lower end of the furnace body 80 and acts on the end of the discharge outlet 802, thus limiting the core rod 30. At this time, the air bag 40... The collecting component 60 stays at the bottom of the inner side of the furnace body 80. Then, the lifting mechanism drives the lifting pipe 10 to move upward relative to the core rod 30. The air supply component 20 compresses the air inside the lifting pipe 10 into the air bag 40, thereby driving the air bag 40 to expand. After the air bag 40 expands, it contacts the inner wall of the furnace body 80. The air bag 40 and the collecting component 60 move upward synchronously with the lifting pipe 10. When the air bag 40 moves upward, it cleans the light ash on the inner wall of the furnace body 80. The light ash cleaned by the air bag 40 is collected by the collecting component 60, thereby preventing light ash from filling the inner cavity of the furnace body 80.

[0023] Please see Figure 5In one embodiment, the air supply assembly 20 includes an air supply piston 201, which is movably disposed inside the lifting tube 10. The upper end of the core rod 30 extends from the bottom of the lifting tube 10 into the interior of the lifting tube 10 and is fixedly connected to the bottom wall of the air supply piston 201.

[0024] When the limiting component 50 acts on the end of the discharge port 802 to limit the core rod 30, as the lifting mechanism drives the lifting pipe 10 to move upward, the air supply piston 201 moves downward along the inside of the lifting pipe 10, thereby pressing the air inside the lifting pipe 10 into the air bag 40, causing the air bag 40 to expand and contact the inner wall of the furnace body 80. After the air bag 40 contacts the inner wall of the furnace body 80, as the air bag 40 moves upward with the lifting pipe 10, the air bag 40 can clean the light dust on the inner wall of the furnace body 80.

[0025] Please see Figure 3 , Figure 4 , Figure 7 as well as Figure 8 In one embodiment, a first air inlet 105 is provided on the lower part of the side wall of the lifting pipe 10. The collecting assembly 60 includes a collecting ring block 601, which is fixedly disposed on the outer wall of the lifting pipe 10. A plurality of collecting grooves 604 are provided on the collecting ring block 601, and the plurality of collecting grooves 604 vertically penetrate the collecting ring block 601. A partition net 602 is provided on the bottom inner side of each set of collecting grooves 604. A third air passage 603 is provided inside the collecting ring block 601. The airbag 40 is arranged around the outside of the collecting ring block 601. One end of the third air passage 603 is connected to the first air inlet 105, and the other end is connected to the inner cavity of the airbag 40. A V-shaped fold 401 is provided on the airbag 40, and a plurality of second air inlets 402 are provided inside the V-shaped fold 401.

[0026] Initially, the airbag 40 is in a contracted state outside the collecting ring block 601, the V-shaped fold 401 is in a compressed folded state, and the second air outlet 402 is in a compressed and closed state within the V-shaped fold 401. When the lifting pipe 10 moves upward relative to the air supply piston 201, the air supply piston 201 forces the air inside the lifting pipe 10 through the first air outlet 105 to the inside of the third air passage 603, and then from the third air passage 603 to the inside of the airbag 40, thereby driving the airbag 40 to expand. When the airbag 40 expands and contacts the inner wall of the furnace body 80, the V-shaped fold 401 is affected by the expansion of the airbag 40 and unfolds. At the same time, several second air outlets 402 are affected by the V-shaped fold 401. The unfolding of the folding part 401 leads to an adaptive opening. The airbag 40, maintaining its inflated state, moves upward along the inner wall of the furnace body 80 following the lifting pipe 10. Subsequently, the air supplied by the air supply piston 201 to the inside of the airbag 40 is output from the opened second air outlets 402 and acts on the inner wall of the furnace body 80 located above the airbag 40, blowing the light ash on the inner wall of the furnace body 80 upward. After the light ash is blown upward from the inner wall of the furnace body 80, the airflow carrying the light ash enters the inside of several collection tanks 604 from top to bottom. At this time, the airflow passes through the partition 602, while the light ash is intercepted by the partition 602, so that the light ash is collected inside the collection tanks 604.

[0027] After air is output from several second air outlets 402 and blows upwards away from the light ash on the inner wall of the furnace body 80, to ensure that the airflow can smoothly carry the light ash into the collection tank 604, please refer to... Figure 1 , Figure 2 as well as Figure 3 In one embodiment, the lifting pipe 10 is also movably fitted with a sealing cover 101 that cooperates with the feed port 801, and the sealing cover 101 is provided with a locking bolt 102.

[0028] After the limiting component 50 extends from the discharge port 802 and limits the core rod 30, the sealing cover 101 covers the feed port 801. At this time, the operator can tighten the locking bolt 102 so that the locking bolt 102 pushes against the side wall of the feed port 801, thereby limiting the sealing cover 101 to the feed port 801 and sealing the feed port 801. In this way, after the air is output from several second air outlets 402 and blows the light ash on the inner wall of the furnace body 80 upward, the airflow cannot carry the light ash out of the feed port 801. The airflow can only carry the light ash into the collection tank 604, thereby ensuring that the light ash can be collected smoothly.

[0029] Please see Figure 8In one embodiment, the airbag 40 has an annular structure. The upper end of the airbag 40 is connected to the upper surface of the collecting ring block 601, and the lower end of the airbag 40 is connected to the annular outer wall of the collecting ring block 601. An elastic support component 70 is also provided on the upper part of the collecting ring block 601 in the inner area of ​​the airbag 40. When the airbag 40 moves to the top position inside the furnace body 80, the elastic support component 70 provides elastic support force to the airbag 40 in the direction of the lifting pipe 10, thereby causing the airbag 40 to contract and drive the upper end of the airbag 40 to adhere to the outer wall of the lifting pipe 10. The upper end of the airbag 40 adheres to the outer wall of the lifting pipe 10, and the airbag 40 can support the collecting groove 601. The area above 04 is shielded to seal the light ash inside the collection tank 604. Then, the operator releases the limiting component 50 from the limiting state of the core rod 30 and simultaneously reverses the locking bolt 102 to contact the limitation between the sealing cover 101 and the feed port 801. Then, the lifting mechanism drives the lifting pipe 10, core rod 30, air bag 40 and limiting component 50 to move upward as a whole, thereby moving the lifting pipe 10, core rod 30, air bag 40 and limiting component 50 to the top of the furnace body 80, realizing the reset of the lifting pipe 10, core rod 30, air bag 40 and limiting component 50. During this process, the light ash collected in the collection tank 604 is shielded by the air bag 40, so the light ash cannot escape into the external environment.

[0030] Please see Figure 1 , Figure 4 as well as Figure 8 In one embodiment, the upper part of the side wall of the lifting pipe 10 is provided with an exhaust hole 103, the side wall of the air supply piston 201 is provided with a first air passage 202, the upper part of the air supply piston 201 is provided with a second air passage 203, the second air passage 203 is connected to the first air passage 202, the elastic support assembly 70 includes a pressure plate 701 and a third elastic element 702, the pressure plate 701 is provided in several groups, the several pressure plates 701 are hinged to the upper part of the collecting ring block 601, the several pressure plates 701 are distributed in a ring at intervals on the upper part of the collecting ring block 601, the several pressure plates 701 are in contact with the inner wall of the airbag 40, and one side of each group of pressure plates 701 is connected to the collecting ring block 601 through a group of third elastic elements 702, the third elastic element 702 is used to provide elastic support for the pressure plate 701.

[0031] Initially, several pressure plates 701 act on the inner wall of the airbag 40 under the elastic support of the third elastic element 702, causing the airbag 40 to be in close contact with the outer wall of the riser pipe 10, thereby blocking the collection grooves 604. When the air supply piston 201 moves down along the inside of the riser pipe 10, the air inside the riser pipe 10 enters the airbag 40 through the first air inlet 105 and the third air passage 603, thereby driving the airbag 40 to inflate. When the airbag 40 inflates, it drives the pressure plates 701 to overcome the elastic support force of the third elastic element 702 and rotate relative to the collection ring block 601. The airbag 40 moves away from the outer wall of the riser pipe 10, exposing the collection grooves 604 so that after the airflow blows the light ash on the inner wall of the furnace body 80, the airflow can carry the light ash into the collection grooves 604. The collection of light ash is achieved. When the airbag 40 moves to the top of the inner side of the furnace body 80, the first air outlet 105 moves to the side of the first air passage 202 and communicates with the first air passage 202. At this time, the air inside the airbag 40 flows into the riser pipe 10 through the third air passage 603, the first air outlet 105, the first air passage 202 and the second air passage 203, and then is discharged to the outside through the exhaust hole 103. At the same time, the third elastic element 702 pushes the pressure plate 701 to rotate in the opposite direction along the upper part of the collection ring block 601. When the pressure plate 701 rotates in the opposite direction, it pushes the airbag 40 to contract. When the airbag 40 contracts, it separates from the inner wall of the furnace body 80 on the one hand, and acts on the outer wall of the riser pipe 10 on the other hand, thereby blocking the collection tank 604 to prevent the light ash inside the collection tank 604 from escaping outward.

[0032] Please see Figure 3 as well as Figure 6 In one embodiment, the limiting component 50 includes a limiting rod 501, a turntable 502, and a second elastic element 503. The limiting rod 501 is provided in several groups, and several limiting rods 501 are hinged to the bottom of the side wall of the core rod 30. The upper part of each group of limiting rods 501 is connected to the outer wall of the core rod 30 through a group of second elastic elements 503. The second elastic elements 503 are used to provide elastic support for the limiting rods 501. The turntable 502 is rotatably disposed at the bottom of the core rod 30, and the turntable 502 has several slots 504 that correspond one-to-one with the limiting rods 501.

[0033] Initially, the slots 504 and the limiting rods 501 are staggered. When the core rod 30 is inserted into the furnace body 80 through the feed inlet 801, the limiting rods 501 act on the upper end of the feed inlet 801, thus overcoming the elastic support force of the second elastic element 503 and rotating upward relative to the core rod 30. After the core rod 30 drives the limiting rods 501 into the furnace body 80, the limiting rods 501 rotate downward relative to the core rod 30 under the elastic support of the second elastic element 503. When the limiting rods 501 move downward along the interior of the furnace body 80 and contact the inner bottom wall of the furnace body 80, the limiting rods 501 again rotate downward relative to the core rod 30. As the core rod 30 rotates upwards, when several limiting rods 501 follow the core rod 30 through the inside of the discharge port 802 and move to a position below the discharge port 802, the limiting rods 501 rotate downwards again relative to the core rod 30. At this time, the limiting rods 501, under the elastic support of several second elastic elements 503, abut against the upper end of the turntable 502 and remain horizontally distributed. Subsequently, the lifting mechanism drives the lifting tube 10 to move upwards, and the lifting tube 10 drives the limiting rods 501 and the turntable 502 to move upwards until the limiting rods 501 act on the lower end of the discharge port 802, at which point the core rod 30 completes its limiting. Afterwards, as the lifting tube 10 continues to move upwards, the air supply piston 201 moves along... The lifting pipe 10 moves downward, thereby compressing air into the airbag 40, causing the airbag 40 to inflate and contact the inner wall of the furnace body 80. When the airbag 40 moves to the top of the inner side of the furnace body 80, the operator can rotate the turntable 502, causing several slots 504 to rotate to positions below several limit rods 501. Then, the lifting mechanism drives the lifting pipe 10 to continue moving upward, and the lifting pipe 10 drives the core rod 30 to move upward. As the core rod 30 moves upward, it pulls several limit rods 501, causing them to move downward relative to the core rod 30 and pass through the corresponding slots 504 until the limit rods 501 rotate to a predetermined angle. 01 separates from the lower end of the discharge port 802 and is then pulled into the furnace body 80 by the core rod 30. Subsequently, as the core rod 30 drives several limiting rods 501 to move upward along the inside of the furnace body 80, when the several limiting rods 501 contact the inner top wall of the furnace body 80, the several limiting rods 501 rotate downward relative to the core rod 30 again and pass through several slots 504 again. When the several limiting rods 501 rotate at a predetermined angle again, the several limiting rods 501 are pulled out from the feed port 801 by the core rod 30. At this point, the lifting pipe 10, core rod 30, air bag 40, collecting ring block 601 and several limiting rods 501 move as a whole to the top of the furnace body 80, thereby completing the reset.

[0034] Please see Figure 3 as well as Figure 5In one embodiment, the upper end of the air supply piston 201 is connected to the inner top wall of the lifting pipe 10 through a first elastic element 204. The first elastic element 204 is used to provide elastic tension to the air supply piston 201. An air inlet pipe 104 is provided at the bottom of the lifting pipe 10, and a one-way valve (not shown in the figure) is provided inside the air inlet pipe 104.

[0035] When the riser pipe 10 moves upward relative to the gas supply piston 201, the first elastic element 204 is stretched by force, the one-way valve inside the gas inlet pipe 104 is closed, and the gas supply piston 201 pushes the air inside the riser pipe 10 through the first gas outlet 105 and the third gas passage 603 into the gas bag 40, causing the gas bag 40 to expand and contact the inner wall of the furnace body 80; after the turntable 502 rotates so that the slots 504 rotate to the position below the limit rods 501, the first elastic element 204 pulls the gas supply piston 201 so that the gas supply piston 201 moves upward along the inside of the riser pipe 10. This causes the core rod 30 to move upward relative to the riser tube 10, thereby resetting the gas supply piston 201 and the core rod 30. When the core rod 30 moves upward and resets, it can pull several limit rods 501 so that the limit rods 501 rotate downward relative to the core rod 30, so that the limit rods 501 can quickly enter the furnace body 80 through the discharge port 802. When the gas supply piston 201 moves upward along the inside of the riser tube 10, the one-way valve inside the air inlet pipe 104 opens, and outside air is drawn from the inside of the air inlet pipe 104 into the inside of the riser tube 10, realizing automatic air replenishment.

[0036] In one embodiment, the first elastic element 204, the second elastic element 503, and the third elastic element 702 can be springs or metal sheets, and there is no limitation here.

[0037] In one embodiment, the partition 602 is detachably disposed at the bottom of the inner side of the collection tank 604. Specifically, the detachable connection between the partition 602 and the inner side of the collection tank 604 can be a screw connection or a snap-fit ​​connection, which is not limited here.

[0038] After the lifting pipe 10, core rod 30, air bag 40, collection ring block 601 and several limiting rods 501 are moved to the top of the furnace body 80 to complete the reset, the staff can remove the partition net 602 from the bottom inside the collection tank 604 and then clean the light ash inside the collection tank 604.

[0039] In one embodiment, the lifting mechanism can be a linear motor or a hydraulic cylinder, and there is no limitation on it.

[0040] In this embodiment of the invention, when it is necessary to clean the light ash on the inner wall of the furnace body 80, a lifting mechanism (not shown in the figure) can be used to move the lifting pipe 10, core rod 30, air bag 40, limiting component 50, and collecting component 60 downwards as a whole. When the lifting pipe 10, core rod 30, air bag 40, limiting component 50, and collecting component 60 move downwards, they enter the furnace body 80 from the feed inlet 801 at the upper end of the furnace body 80. After the limiting component 50 enters the furnace body 80, it extends out from the discharge outlet 802 at the lower end of the furnace body 80 and acts on the end of the discharge outlet 802 to limit the core rod 30. At this time, the air bag 40 and collecting component 60 remain at the bottom of the inner side of the furnace body 80. Then, the lifting mechanism drives the lifting pipe... As the core rod 30 moves upward, the air supply component 20 pressurizes the air inside the lifting pipe 10 into the airbag 40, thereby causing the airbag 40 to expand. After the airbag 40 expands, it contacts the inner wall of the furnace body 80. The airbag 40 and the collection component 60 move upward synchronously with the lifting pipe 10. When the airbag 40 moves upward, it cleans the light ash on the inner wall of the furnace body 80. The light ash cleaned by the airbag 40 is collected by the collection component 60, thereby preventing light ash from filling the inner cavity of the furnace body 80. Compared with the prior art, it can automatically clean the light ash on the inner wall of the furnace body 80 and collect the cleaned light ash, thereby preventing light ash from escaping into the surrounding environment and achieving effective protection of the surrounding environment.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity, and those skilled in the art should consider the specification as a whole.
