Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The boiler ash and slag cleaning device of the present invention is described below with reference to the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the boiler ash cleaning device of this embodiment includes a boiler body 1, a flue pipe 2 at the bottom of the boiler body 1, and a purification box 3 at the outlet end of the flue pipe 2. The purification box 3 is hinged with a door (not shown in the figure), and the door is surrounded by a sealing ring. The door facilitates the inspection and maintenance of the internal structure of the purification box 3.

[0030] The bottom of the purification chamber 3 is equipped with a placement compartment 4, which is filled with adsorbent (activated carbon) so that the flue gas discharged from the exhaust pipe 2 into the purification chamber 3 is purified by the adsorbent. The inner wall of the purification chamber 3 is equipped with a vertical groove 7, and a movable plate 8 that slides along the vertical groove 7 is provided inside the purification chamber 3. A filter plate 16 is snapped onto the movable plate 8. The top of the purification chamber 3 is equipped with an exhaust port 6 so that the purified flue gas is filtered by the filter plate 16 and discharged through the exhaust port 6, thereby achieving the purification treatment of the flue gas.

[0031] The movable plate 8 is connected to the top of the purification box 3 via the first spring 9. The top of the purification box 3 is provided with a hollow column 10. The bottom of the hollow column 10 is connected to a top block 11 via a second spring (not shown in the figure). The top block 11 abuts against the filter plate 16.

[0032] By forcing the filter plate 16 to move downward against the pull of the first spring 9, in the process, the top block 11 originally pressed by the filter plate 16 is ejected under the action of the second spring. When the filter plate 16 moves down to the limit position, the filter plate 16 is released, and the elastic potential energy stored by the first spring 9 is released instantaneously, driving the filter plate 16 to rebound rapidly and hit the top block 11 to achieve unblocking.

[0033] In some embodiments, as shown in Figures 1 to 8 The bottom of the movable plate 8 is provided with a rack 12, the rack 12 is provided with a hollow rod 13, and the end of the hollow rod 13 is connected with an iron block 15 through a reset spring 14. The bottom of the filter plate 16 is provided with an L-shaped magnet rod 17, and the end plate of the magnet rod 17 is provided with a notch 18 matched with the iron block 15. A threaded rod 20 is arranged in the purification tank 3, and the end of the threaded rod 20 is provided with a motor 19 fixed on the outer wall of the purification tank 3, and the threaded rod 20 is provided with a pressing rod 21 corresponding to the position of the iron block 15.

[0034] The magnet rod 17 is energized to generate a strong magnetic field, and the magnetic force overcomes the force of the reset spring 14 to quickly adsorb the iron block 15 into the notch 18 of the magnet rod 17, realizing the rigid connection of the hollow rod 13 and the magnet rod 17. Subsequently, the motor 19 drives the threaded rod 20 to rotate, driving the pressing rod 21 to press the iron block 15 assembly in the connected state, forcing the filter plate 16 to move downward against the pull of the first spring 9.

[0035] When the filter plate 16 moves down to the limit position (when contacting the movable block 30), the power supply of the magnet rod 17 is immediately cut off, and the iron block 15 is separated from the magnet rod 17 under the action of the reset spring 14. At this time, the pressing action of the pressing rod 21 disappears, and the elastic potential energy stored by the first spring 9 is released instantaneously, driving the filter plate 16 to rebound rapidly and hit the top block 11 to achieve unblocking.

[0036] In some embodiments, as shown in Figures 1 to 8 The inside of the placing bin 4 is provided with a turning plate 24, the turning plate 24 is provided with a rotating shaft, and the rotating shaft is sleeved with a first gear 25 engaged with the rack 12, so that the rack 12 moves and drives the turning plate 24 to rotate through the first gear 25.

[0037] When the filter plate 16 moves downward, the filter plate 16 drives the rack 12 to descend, the rack 12 drives the first gear 25 to rotate, and the turning plate 24 is driven to rotate through the rotating shaft, the rotation of the turning plate 24 turns the adsorbent in the placing bin 4, which is beneficial to prevent the adsorbent from caking, and at the same time, the turning of the turning plate 24 makes the adsorbent in the upper and lower layers move, preventing the adsorbent in the upper layer from being used for a long time. The utilization rate is low, and the above operation improves the purification effect.

[0038] Further, the placing bin 4 is provided with a hollow plate 23 extending out of the purification box 3, and the part of the rack 12 engaged with the first gear 25 is located in the hollow plate 23. The hollow plate 23 isolates the engagement between the rack 12 and the first gear 25, preventing the adsorbent from being stuck in the teeth and not conducive to rotation, thereby improving the reliability of the device operation.

[0039] In some embodiments, as shown in Figures 1 to 8 The purification box 3 is provided with a collection box 26 located between the filter plate 16 and the placing bin 4, and the collection box 26 is provided with an expansion plate 27. The inner wall of the purification box 3 is provided with a horizontal groove 29, and the purification box 3 is provided with a movable block 30 sliding along the horizontal groove 29, and the movable block 30 is connected with the expansion plate 27. The movable block 30 is provided with an assembly hole 31 with an adjustable hole diameter, and the threaded rod 20 penetrates through the assembly hole 31. After the hole diameter of the assembly hole 31 matches the threaded rod 20, the threaded rod 20 drives the movable block 30 to move.

[0040] Before the filter plate 16 performs the clogging and dredging operation, the hole diameter of the assembly hole 31 matches the threaded rod 20, so that the motor 19 drives the threaded rod 20 to rotate and drives the movable block 30 to translate under the limiting action of the horizontal groove 29, without driving the movable block 30 to rotate synchronously, thereby driving the folded expansion plate 27 to lengthen and expand, so that the expansion plate 27 is completely laid above the adsorbent, which is conducive to the subsequent clogging and dredging process of the filter plate 16, so that the impurities thrown out by the filter plate 16 fall on the expansion plate 27, preventing them from falling directly on the adsorbent and causing pollution.

[0041] After the expansion plate 27 is completely expanded, the hole diameter of the assembly hole 31 is adjusted to separate the movable block 30 from the threaded rod 20, and then the magnet rod 17 is energized to perform the clogging and dredging operation of the filter plate 16.

[0042] Further, the expansion plate 27 is inclined towards the collection box 26, so that the impurities falling on the folded plate will slide down the slope into the collection box 26, which can be easily cleaned by opening the box door and pulling out the collection box 26, improving the convenience of cleaning.

[0043] In some embodiments, as shown in Figures 1 to 8 The movable block 30 is provided with a motor 32, the output shaft of the motor 32 is sleeved with a second gear 33, and the second gear 33 is engaged with a gear ring 34. The gear ring 34 is connected with a plurality of arc blocks 35 through connecting rods 36, the plurality of arc blocks 35 are arranged at intervals around the central axis of the gear ring 34, and the inner arc surfaces of the plurality of arc blocks 35 jointly define the assembly hole 31. The motor 32 drives the plurality of arc blocks 35 to move synchronously along the radial direction of the gear ring 34 through the second gear 33 and the gear ring 34, so as to adjust the hole diameter of the assembly hole 31.

[0044] It can be understood that the structure of rotating the gear ring 34 to drive the plurality of arc blocks 35 to move close to or away from each other is similar to the aperture structure of a camera, and the aperture of the assembly hole 31 is adjusted to enable the movable block 30 to cooperate with or disengage from the threaded rod 20.

[0045] Specifically, the inner arc surface of the arc block 35 is provided with threads, and the threads of the arc block 35 match the external threads of the threaded rod 20. By rotating the gear ring 34 to engage the arc block 35 with the threaded rod 20, the threaded rod 20 is rotated and the movable block 30 is translated.

[0046] In some embodiments, as shown in Figures 1 to 8 The inner wall of the purification tank 3 is provided with a chute 28, and the movable block 30 is provided with an empty slot 37, in which a right-angle rod 38 is slidingly connected. The right-angle rod 38 is provided with an extension rod 39 slidingly fitted in the chute 28, and the right-angle rod 38 is connected to the telescopic plate 27.

[0047] During the translation of the movable block 30, the right-angle rod 38 gradually retracts into the empty slot 37 under the action of the chute 28, so that the right-angle rod 38 drives the telescopic plate 27 to tilt and expand, so that the impurities can slide down the slope into the collection box 26.

[0048] Further, the movable block 30 is slidingly connected with a vertical rod 40, the bottom of the vertical rod 40 is provided with a tamping plate 42 located in the storage bin 4, the vertical rod 40 is sleeved with a telescopic spring 41, and the top of the vertical rod 40 is in sliding contact with the outer arc surface of the arc block 35.

[0049] When the threaded rod 20 does not rotate, the arc block 35 is driven to reciprocate by the motor 32 to press the vertical rod 40, and the vertical rod 40 is reset under the action of the telescopic spring 41 after descending, so that the vertical rod 40 drives the tamping plate 42 to reciprocate, and the adsorbent is tamped by the reciprocating tamping plate 42, preventing the adsorbent from caking. Moreover, the position of tamping can be changed by moving the movable block 30.

[0050] In summary, the operation principle of the boiler ash cleaning device of the embodiment of the present application is described below.

[0051] Since the waste residue falling from the filter plate 16 will fall on the adsorbent during the unblocking process of the filter plate 16, it is necessary to completely expand the telescopic plate 27 to cover the adsorbent before cleaning. When the telescopic plate 27 is expanded, the threads on the outer surface of the threaded rod 20 are separated from the engagement state of the arc block 35, preventing the expanded telescopic plate 27 from being folded during the movement of the movable block 30 during the unblocking process.

[0052] After the preparation work is completed, the clogging cleaning work is started, the magnet rod 17 is powered to generate a strong magnetic field, the strong magnetic force at this time overcomes the force exerted by the reset spring 14 on the iron block 15, and then the iron block 15 is stretched and sucked into the slot 18 under the action of the strong magnetic force. At this time, the reset spring 14 is elongated and ready to reset the iron block 15 when the power is off, which is beneficial to the connection of the hollow rod 13 and the magnet rod 17.

[0053] The motor 19 starts to rotate with the threaded rod 20 and the pressing rod 21. When the pressing rod 21 rotates, it presses the iron block 15. Since the hollow rod 13 and the magnet rod 17 are in a connected state at this time, pressing the iron block 15 will cause the hollow rod 13 and the magnet rod 17 to descend. Since the magnet rod 17 is fixedly connected to the bottom of the filter plate 16, the filter plate 16 will also descend and stretch the first spring 9. At this time, the top block 11 lacks the blocking of the filter plate 16 and extends under the action of the second spring inside it.

[0054] When the filter plate 16 descends to contact the top of the movable block 30, it will no longer descend. At this time, the iron block 15 resets when the magnet rod 17 is powered off, causing the hollow rod 13 and the magnet rod 17 to separate from the connected state. Then the pressing force of the pressing rod 21 on the iron block 15 disappears. At this time, the movable plate 8 with the filter plate 16 rapidly rebounds along the vertical slot 7 and hits the top block 11 under the resetting action of the first spring 9. Through the rapid rebounding effect, the top block 11 is hit, causing the impurities clogged in the holes of the filter plate 16 to be thrown out.

[0055] At the same time, the rapid rebounding hits the top block 11 and the second spring in the hollow column 10, causing the second spring to vibrate and transmit to the filter plate 16. The vibrations generated by the two groups of springs are transmitted to the filter plate 16. The vibration force causes the impurities in the holes of the filter plate 16 to break, and under the action of "vibration-impact", the impurities in the holes of the filter plate 16 are thrown out to the greatest extent, thereby realizing the cleaning of the filter plate 16 to prevent clogging. When the filter plate 16 is severely deformed or damaged after long-term use, the door needs to be opened for replacement.

[0056] During the descent of the filter plate 16, the rack 12 descends inside the hollow plate 23, and then descends with the first gear 25 and the turning plate 24 rotating. The hollow plate 23 isolates the meshing part of the rack 12 and the first gear 25, preventing the activated carbon from being stuck in the teeth and preventing rotation. The turning plate 24 rotates to turn the adsorbent in the storage bin 4.

[0057] The expansion of the telescopic plate 27 is independent of the clogging cleaning of the filter plate 16, and the telescopic plate 27 is expanded while the filter plate 16 is stopped for cleaning, and vice versa. The motor 32 is started to rotate the second gear 33, and then the gear ring 34 is rotated, the gear ring 34 is synchronously moved through the connecting rod 36 with the arc-shaped block 35, then the screw thread of the arc-shaped block 35 is engaged with the screw thread outside the screw rod 20, at this time, when the screw rod 20 is rotated, the pressing rod 21 will pass through the gap between the hollow rod 13 and the magnet rod 17 and cannot realize the cleaning operation.

[0058] Due to the screw thread engagement, the rotation of the screw rod 20 will move the movable block 30 along the horizontal groove 29, and the extension rod 39 moves in the inclined groove 28, at this time, the movable block 30 pulls the folded telescopic plate 27 to be lengthened and completely expanded and laid on the top of the adsorbent, which is beneficial to make the impurities shaken off from the filter plate 16 fall on the telescopic plate 27, preventing the impurities from directly falling on the adsorbent to cause pollution.

[0059] And due to the inclined design of the inclined groove 28, and the right-angle rod 38 is retracted into the hollow groove 37 during the movement, therefore, the expanded telescopic plate 27 is inclined towards the collection box 26, and the surface of the telescopic plate 27 is smooth, so the impurities falling on the inclined telescopic plate 27 will slide along the slope to the collection box 26, and the collection box 26 can be cleaned by regularly opening the box door.

[0060] When the cleaning operation is not performed, the motor 32 is started to reciprocate the arc-shaped block 35 to press the vertical rod 40, the vertical rod 40 is lowered and then is reset to be raised under the action of the telescopic spring 41, thereby realizing the reciprocating lifting of the vertical rod 40 and the tamping plate 42, the adsorbent is tamped through the reciprocating lifting of the tamping plate 42, so that the adsorbent is vibrated to further prevent the adsorbent from being hardened, and the position of tamping is changed through the movement of the movable block 30.
