Description

Technical Field

[0001] The invention relates to the field of cleaning technology, and more particularly to a cleaning device for a fly ash bin. Background Art

[0002] Fly ash is an industrial by-product produced in the process of burning coal in coal-fired power plants. It is mainly formed by the non-combustible substances in the coal through gasification and condensation at high temperatures. The fly ash silo collects the fly ash separated from the boiler flue gas by the dust collector for subsequent processing and utilization.

[0003] Fly ash may adhere to the inner wall of the silo during storage. When the ambient humidity is high or the seal is not tight, the fly ash may absorb moisture in the air and form lumps. The lumps adhere to the inner wall of the fly ash silo to form stubborn scale. In particular, the scale in the lower conical section of the fly ash silo seriously affects the flow and discharge of the fly ash. Currently, the scale is mainly cleaned by air cannons or water jets. Although air cannons or water jets can effectively clear the discharge port of the fly ash silo, they are still unable to completely remove the stubborn scale attached to the inner wall of the lower conical section.

[0051] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0052] See also Figure 1 and Figure 2 , the present invention discloses a fly ash bin cleaning device, which is applied to a fly ash bin 100, wherein the fly ash bin 100 comprises an upper straight cylinder section 101 and a lower conical section 102 which are integrally spliced;

[0053] See also Figure 4 and Figure 5The cleaning device of the fly ash bin includes a mounting ring 200, a rotating ring 300, a flip plate 400, a descaling unit 500 and a dredging unit 600; the mounting ring 200 is movably arranged in the upper straight section 101 of the fly ash bin 100; the rotating ring 300 is rotatably arranged below the mounting ring 200, and the mounting ring 200 is provided with a rotating driving member for driving the rotating ring 300; the upper end of the flip plate 400 is rotatably arranged on the rotating ring 300, and the rotating ring 300 is provided with a flip driving member 320 for driving the flip plate 400; the descaling unit 500 is movably arranged on the flip plate 400, and is used to remove the scale on the inner wall of the lower conical section 102 of the fly ash bin 100; the dredging unit 600 is arranged at one end of the flip plate 400 away from the rotating ring 300, and is used to dredge the scale at the outlet of the lower conical section 102;

[0054] When the mounting ring 200 reaches the joint of the upper straight tube section 101 and the lower conical section 102, the flip plate 400 is driven by the flip driving member 320 to flip downward to be parallel to the slope of the lower conical section 102, and then the rotating ring 300 is driven by the rotating driving member to rotate circumferentially relative to the mounting ring 200. At the same time, the descaling unit 500 moves downward along the flip plate 400, and the descaling unit 500 is used to perform circumferential full coverage descaling of the lower conical section 102, and the dredging unit 600 dredges the scale at the outlet of the lower conical section 102.

[0055] Specifically, in the initial state, the mounting ring 200 is at the top of the upper straight section 101, and the flip plate 400 is also flipped to a horizontal state, so that the entire cleaning device is stored and folded at the upper end of the fly ash bin 100, without affecting the normal feeding and discharging of fly ash;

[0056] When it is necessary to clean the scale on the lower conical section 102 of the fly ash bin 100, the mounting ring 200 is lowered to the joint of the upper straight cylinder section 101 and the lower conical section 102 and fixed to the fly ash bin 100, and then the flip plate 400 is flipped downward to an inclined state by the flip driving member 320, so that the inclination of the flip plate 400 is consistent with the inclination of the inner wall of the lower conical section 102; the rotating ring 300 is driven to rotate circumferentially by the rotating driving member, and the descaling unit 500 moves from top to bottom along the flip plate 400, so that the descaling unit 500 can be used to descale the inner conical surface of the lower conical section 102 layer by layer, and the scale is separated from the inner conical surface of the lower conical section 102 and slides downward along the lower conical section 102 to the discharge port at the lower end of the fly ash bin 100, and the dredging unit 600 at the lower end of the flip plate 400 is used to dredge the accumulated scale so that the scale can be discharged smoothly.

[0057] In one embodiment, see Figure 2 and Figure 3, for the lifting movement of the mounting ring 200, a plurality of lifting guide rails 110 are vertically arranged in the upper straight tube section 101, a lifting screw 120 is rotatably installed in the lifting guide rail 110, a lifting slider 210 adapted to the lifting guide rail 110 is arranged on the mounting ring 200, the lifting slider 210 is threadedly connected with the lifting screw 120, and a lifting motor (not shown in the figure) for driving the lifting screw 120 is installed on the top of the upper straight tube section 101;

[0058] Specifically, the lifting motor drives the lifting screw 120 to rotate, thereby driving the lifting slider 210 to slide along the corresponding lifting guide rail 110, so as to realize the lifting movement of the mounting ring 200, so as to drive the mounting ring 200 to adjust its height;

[0059] It should be noted that in order to prevent fly ash from entering the lifting guide rail 110 and affecting the normal sliding of the lifting slider 210, in actual applications, a soft wrapping cover can be provided outside the lifting guide rail 110. The soft cover does not affect the normal passage of the lifting slider 210 and can remain in a closed state after being separated from the lifting slider 210.

[0060] For further information, see Figure 4 The rotary drive member includes a rotary motor 220 fixed on the mounting ring 200, a rotary gear 230 is provided at the output end of the rotary motor 220, and a gear ring 310 meshing with the rotary gear 230 is provided on the rotating ring 300;

[0061] The rotating gear 230 is driven to rotate by the rotating motor 220 , and the rotating ring 300 is driven to rotate circumferentially relative to the mounting ring 200 under the meshing transmission of the rotating gear 230 and the gear ring 310 , so as to realize circumferential descaling of the descaling unit 500 .

[0062] For further information, see Figure 6 The flip driving member 320 includes a mounting plate 321 integrally connected to the rotating ring 300, a cylinder 322 is vertically fixed on the mounting plate 321, a bayonet 323 is provided at the extended end of the cylinder 322, a first slide groove 401 is provided on the flip plate 400, and the bayonet 323 is movably embedded in the first slide groove 401;

[0063] In the initial state, the extended end of the cylinder 322 is retracted, so that the flip plate 400 is flipped to a horizontal state. When the lower conical section 102 needs to be descaled, the extended end of the cylinder 322 is extended downward, and the latch 323 is used to push the flip plate 400 downward, so that the flip plate 400 is flipped downward and unfolded, and at the same time, the latch 323 slides adaptively in the first slide groove 401;

[0064] It should be noted that the distribution positions of the mounting plate 321 and the cylinder 322 will not interfere with the rotating motor 220 and the rotating gear 230 , and thus will not affect the normal rotation movement of the rotating ring 300 .

[0065] In addition, in order to avoid relative movement between the mounting ring 200 and the fly ash bin 100 during the descaling process and thus affect the stability of the descaling process, the mounting ring 200 and the fly ash bin 100 need to be relatively fixed. Figure 8 The mounting ring 200 is embedded with an annular airbag 240, and the mounting ring 200 is rotatably sealed with the rotating ring 300. An annular ventilation groove 201 is provided at the sealing connection between the mounting ring 200 and the rotating ring 300, and a first air passage 202 is connected between the annular ventilation groove 201 and the annular airbag 240; a second air passage 301 is provided in the mounting ring 200, and one end of the second air passage 301 is connected with the inside of the cylinder 322, and the other end of the second air passage 301 is connected with the annular ventilation groove 201;

[0066] Specifically, when the extended end of the cylinder 322 is in a retracted state to drive the flip plate 400 to flip to a horizontal storage state, the air in the annular airbag 240 is sucked into the cylinder 322 through the first air channel 202, the annular vent groove 201 and the second air channel 301 under the drive of the piston in the cylinder 322, so that the annular airbag 240 is retracted into the mounting ring 200, which facilitates the storage and lifting movement of the mounting ring 200;

[0067] When the extended end of the cylinder 322 extends downward to drive the flip plate 400 to flip and unfold downward, the piston inside the cylinder 322 squeezes out the air in the cylinder 322, and the squeezed air enters the annular airbag 240 through the second air channel 301, the annular vent groove 201 and the first air channel 202, so that the annular airbag 240 expands and contacts the inner wall of the fly ash bin 100, so as to complete the fixing between the mounting ring 200 and the fly ash bin 100;

[0068] It is worth noting that when the cylinder 322 drives the flip plate 400 to be retracted, it can also drive the annular airbag 240 to be synchronously retracted into the mounting ring 200; similarly, when the cylinder 322 drives the flip plate 400 to be unfolded, it can also drive the annular airbag 240 to be synchronously inflated and popped out from the mounting ring 200, so as to improve the synchronization of the states of the mounting ring 200 and the flip plate 400 and the efficiency of the posture switching between the two.

[0069] In yet another embodiment, see Fig. 9 and Fig.10 The flip plate 400 is provided with a second slide groove 405, the descaling unit 500 is slidably disposed in the second slide groove 405, a moving screw rod 430 is rotatably installed in the second slide groove 405, and the descaling unit 500 is threadedly connected to the moving screw rod 430;

[0070] See also Figure 6 and Figure 7 A moving motor 410 is fixedly mounted on one end of the flip plate 400, and the output end of the moving motor 410 is connected to the moving screw rod 430 through a transmission belt 420. A through slot 404 for accommodating the transmission belt 420 is provided on the flip plate 400;

[0071] Specifically, under the transmission of the transmission belt 420 , the moving motor 410 drives the moving screw 430 to rotate, thereby driving the descaling unit 500 to move along the second slide groove 405 , so as to achieve layer-by-layer descaling and cleaning of the lower conical section 102 by the descaling unit 500 .

[0072] Considering the stability of the flip plate 400 when following the rotating ring 300 to rotate circumferentially relative to the mounting ring 200, ball sleeves 402 are provided at both ends of the flip plate 400, and balls 403 are movably embedded in the ball sleeves 402. The balls 403 are rollingly adapted to the inner conical surface of the lower conical section 102;

[0073] When the flip plate 400 is flipped downward to the same inclination as the lower conical section 102, the balls 403 at both ends of the flip plate 400 just contact the inner conical surface of the lower conical section 102. When the flip plate 400 rotates circumferentially relative to the lower conical section 102, the balls 403 roll circumferentially along the inner conical surface of the lower conical section 102. The balls 403 can not only support the flip plate 400 so that the flip plate 400 always remains parallel to the inner conical surface of the lower conical section 102, but also effectively reduce the resistance of the flip plate 400 during rotation, so that the flip plate 400 moves more smoothly.

[0074] See also Fig.11 and Fig.12 The descaling unit 500 includes a moving block 510 slidably arranged in the second slide groove 405, and the moving block 510 is threadedly connected with the moving screw 430; a sliding rod 520 is slidably arranged on the moving block 510, and a knocking piece 530 is arranged near one end of the sliding rod 520; a cavity 511 is opened in the moving block 510, and a fan-shaped plate 560 is rotatably arranged in the cavity 511, and a connecting rod 570 is fixed on the fan-shaped plate 560, and a shovel plate 580 is arranged at one end of the connecting rod 570 away from the fan-shaped plate 560; a reciprocating drive component for driving the sliding rod 520 and the fan-shaped plate 560 to reciprocate synchronously is also arranged on the moving block 510;

[0075] Specifically, the reciprocating drive assembly drives the slide rod 520 to slide back and forth relative to the moving block 510, thereby driving the knocking member 530 to periodically knock the scale on the inner conical surface of the lower conical section 102, so that the scale is broken and separated from the lower conical section 102; at the same time, the reciprocating drive assembly drives the fan plate 560 to swing back and forth, thereby driving the shovel plate 580 to periodically shovel the detached scale to one side, thereby achieving effective cleaning of the scale on the lower conical section 102.

[0076] It should be noted that the shovel plate 580 can not only remove the detached scale, but also perform secondary cleaning on the scale that is not completely knocked off by the knocking piece 530, so that the scale on the lower conical section 102 can be completely cleaned.

[0077] For further information, see Fig.11 and Fig.12 The reciprocating drive assembly includes a drive motor 540 fixed on the moving block 510 and a rotating shaft 550 rotatably mounted on the moving block 510. The output end of the drive motor 540 is connected to an eccentric rod 541. The end of the eccentric rod 541 away from the output end of the drive motor 540 is provided with a lever 542. The end of the slide bar 520 away from the knocking member 530 is provided with a drive block 543. A slot 544 is provided in the drive block 543. The lever 542 is movably embedded in the slot 544. The flip plate 400 is provided with an avoidance groove 406 for accommodating the drive motor 540 and the slide bar 520.

[0078] The two ends of the rotating shaft 550 are respectively provided with a first gear 551 and a second gear 552, the sliding rod 520 is provided with a straight rack 521 meshing with the first gear 551, and the sector plate 560 is provided with an arc-shaped rack 561 meshing with the second gear 552;

[0079] Specifically, the driving motor 540 drives the lever 542 at the end of the eccentric rod 541 to make a circular motion around the axis of the output end of the driving motor 540, and the lever 542 cooperates with the driving block 543 to drive the sliding rod 520 to slide back and forth, so as to realize the reciprocating knocking operation of the knocking member 530; during the reciprocating sliding of the sliding rod 520, the meshing transmission of the spur rack 521 and the first gear 551 is used to drive the rotating shaft 550 to rotate synchronously, and then under the meshing transmission of the second gear 552 and the arc-shaped rack 561, the fan-shaped plate 560 is synchronously driven to swing back and forth, so as to realize the reciprocating scraping action of the shovel plate 580;

[0080] It should be noted that, when the knocking member 530 is extended downward to knock the scale, the shovel plate 580 is reset upward, and when the knocking member 530 is lifted upward and reset, the shovel plate 580 is flipped downward to scrape the scale; that is, the actions of the knocking member 530 and the shovel plate 580 are staggered with each other, and there will be no interference between the two. At the same time, the continuous alternation of knocking and scraping operations is ensured to ensure the scale removal efficiency.

[0081] Furthermore, to ensure the knocking effect, please refer to Fig.13 The knocking member 530 includes a plate body 531 fixed to one end of the slide rod 520, and a plurality of first slices 532 and second slices 533 are arranged on the end surface of the plate body 531 away from the slide rod 520, and the first slices 532 and the second slices 533 are vertically distributed to form a plurality of rectangular segmentation cavities;

[0082] When the knocking member 530 knocks the scale, the impact force generated by the slide rod 520 on the plate body 531 causes the first slice 532 and the second slice 533 to be inserted into the scale, thereby dividing the scale and dividing the large scale into several fragments, which is conducive to the disintegration and removal of the scale.

[0083] In further embodiments, see Fig.14 The dredging unit 600 includes a connecting shaft 610 coaxially fixed with the moving screw 430, a cylinder 620 is sleeved on the connecting shaft 610, a plurality of rotary slices 630 are axially distributed on the cylinder 620, and a pointed cone 640 is provided at one end of the cylinder 620 away from the connecting shaft 610, and an oscillation spring 650 is connected to the pointed cone 640;

[0084] When the moving motor 410 drives the moving screw 430 to rotate so as to drive the descaling unit 500 to move along the flip plate 400 as a whole, the moving screw 430 can drive the connecting shaft 610 to rotate synchronously, thereby driving the rotary slice 630 and the oscillation spring 650 to rotate synchronously. The rotating rotary slice 630 can rotary-cut the scale that falls to the bottom of the lower conical section 102, so that large scale is cut into small pieces. The pointed cone 640 can guide the scale chopped by the rotary slice 630 to the outlet of the lower conical section 102. At the same time, the oscillation spring 650 expands circumferentially relative to the cylinder 620 under the action of the rotating centrifugal force, and vibrates after contacting the scale and the inner wall of the lower conical section 102, thereby destroying the static equilibrium state between the scale and the lower conical section 102, thereby prompting the broken scale to be discharged quickly, avoiding the accumulation and blockage of scale at the bottom of the lower conical section 102, and improving the scale discharge efficiency.
