Description

Technical Field

[0001] This invention relates to the field of decomposition furnace cleaning, specifically to a device for cleaning scale buildup in a dry process cement production line decomposition furnace. Background Technology

[0002] A decomposition furnace is a new type of thermal equipment that simultaneously performs fuel combustion, heat exchange, and decomposition reactions. In the production of dry-process cement, various ingredients need to be added to the decomposition furnace for firing. However, the aluminum raw materials added are relatively expensive. After repeated experiments comparing the flammability of raw materials with various formulas and different proportions, a cheap solid waste residue—"gasification slag"—was identified that could reduce the flammability of materials and replace some aluminum raw materials. The gasification slag has an average moisture content of over 40%, leading to severe material blockage on-site. We eliminated the blockage problem by changing the material addition method, adjusting the addition ratio, and modifying the feed pipe and chute. Through repeated experiments, adding 3% "gasification slag" to the ingredients achieved satisfactory results. Replacing 3% red coal gangue with gasification slag reduced raw material procurement costs (red coal gangue purchase price: 69.5 yuan / ton, gasification slag purchase price: 46 yuan / ton).

[0003] However, gasification slag contains a certain amount of heat, which causes severe crust formation inside the decomposition furnace after it enters the furnace. As a result, the crust formation cycle inside the furnace is relatively short, leading to frequent crust removal processes, which seriously affects the stable operation of the decomposition furnace. Currently, crust removal usually involves workers entering the furnace, standing on a platform made of steel pipes, with a winch controlling the platform's lifting and lowering. Workers then use tools such as pneumatic picks or crowbars to remove the crust. This method is not only inefficient and slow but also highly dangerous. Therefore, a crust removal device is needed to clean the crust on the inner walls of large decomposition furnaces. Summary of the Invention

[0004] To address the problems existing in current technology, a scale cleaning device for decomposition furnaces in dry-process cement production lines is provided. The device adjusts the positions of multiple support beams through a spreading mechanism, and cleans the scale through multiple cleaning plates. The stepping wheel can drive the entire device to move spirally along the axis of the decomposition furnace as the cleaning plates reciprocate, thereby improving the scale cleaning effect.

[0005] To address the problems in the existing technology, the technical solution adopted by this invention is as follows:

[0008] Preferably, each cleaning mechanism also includes a guide rail; the guide rail is located on the side of the corresponding support beam away from the axis of the mounting plate, and the length direction of the guide rail is the same as the length direction of the corresponding support beam. The cleaning plate is slidably installed in the corresponding guide rail; each cleaning plate has an installation cavity inside, and a counterweight column is slidably installed inside each installation cavity. Each cleaning plate has a rope hole at the center of one end near the mounting plate that connects to the installation cavity. Multiple guide holes are provided along the circumferential direction at the top edge of each push plate. A traction rope is provided on each counterweight column. The traction rope passes through the rope hole and the guide hole in sequence and is wound around the winch.

[0009] Preferably, each stepping mechanism further includes a fixed plate, a U-shaped plate, and a rack; the fixed plate is located at the end of the corresponding support beam away from the mounting plate, and an inclined plate is provided on the fixed plate; a rotating hole is provided on the inclined plate, and a rotating rod is provided at the center of each stepping wheel, the rotating rod being rotatably disposed in the corresponding rotating hole; a one-way bearing is provided at the end of each rotating rod away from the stepping wheel, and multiple gear teeth are provided on the outer wall of each one-way bearing along the circumferential direction; the U-shaped plate is located on the inclined plate, and connecting holes are provided on the inner walls of both sides of the U-shaped plate, and the rack is provided at both ends. There are connecting rods that can slide within corresponding connecting holes. The rack meshes with the gear teeth on the outer wall of the one-way bearing. Each connecting rod is also fitted with a return spring, which is located inside the C-shaped plate. The top of the C-shaped plate has a rectangular notch, within which a reaction rod is hinged. A push rod is located at the center of the side of the rack away from the one-way bearing. The reaction rod has an elliptical groove for accommodating the push rod, which can slide within the elliptical groove. Each cleaning plate has an L-shaped moving rod that cooperates with the reaction rod.

[0010] Preferably, each triangular insert has a strip-shaped notch that connects to the mounting cavity, and each mounting cavity is also equipped with a prying mechanism that can perform secondary cleaning of the crust as the counterweight column moves.

[0011] Preferably, each prying mechanism includes a flexible steel plate and a pusher plate; each mounting cavity has two limiting plates inside, forming a receiving cavity for accommodating the flexible steel plate, which is connected to the strip notch; the pusher plate is slidably disposed in the receiving cavity, with one end of the pusher plate near the strip notch welded to the flexible steel plate, and the other end of the pusher plate away from the flexible steel plate having a contact plate; each limiting plate has a mounting plate at the end away from the strip notch, each mounting plate has two limiting holes, and each contact plate has a limiting rod corresponding to the limiting hole on the side near the mounting plate, the limiting rod being slidably disposed in the corresponding limiting hole; each limiting rod has a limiting disc at the end away from the contact plate, the diameter of the limiting disc being larger than the inner diameter of the limiting hole; each limiting rod is also fitted with a pull spring, the pull spring being located between the corresponding contact plate and the mounting plate.

[0014] The advantages of this application compared to the prior art are:

[0015] 1. This application utilizes a winch, mounting plate, support beams, hydraulic rods, and expansion rods. Multiple support beams can rotate along corresponding hinge slots, allowing the walking wheel to conform to the inner wall of the decomposition furnace. The inclined walking wheel is simultaneously pulled by the winch using multiple traction ropes, enabling multiple cleaning plates to impact the scale on the inner wall of the decomposition furnace under gravity. Through the cooperation of a fixed plate, a U-shaped plate, and a rack, the inclined walking wheel moves spirally along the decomposition furnace axis as the cleaning plates repeatedly move, thereby improving the cleaning effect on the scale.

[0016] 2. In this application, with the cooperation of the cleaning plate, flexible steel plate and push plate, when the cleaning plate is inserted into the crust at an angle, the cleaning plate stops moving. Under the action of inertia, the counterweight column collides with the contact plate, so that the flexible steel plate can cut off the crust through the strip notch of the triangular insert, thereby avoiding the crust from remaining on the inner wall of the decomposition furnace.

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0038] See Figures 1 to 12As shown, a dry-process cement production line decomposition furnace scale cleaning device includes a winch 1 and an installation plate 2. The winch 1 is fixedly installed at the upper end of the decomposition furnace. Multiple lifting rings 21 are arranged circumferentially on the top of the installation plate 2. The winch 1 is connected to the lifting rings 21 on the top of the installation plate 2 via steel wire. It also includes a support beam 3, a spreading mechanism 4, a cleaning mechanism 5, and a stepping mechanism 6. Multiple hinge grooves 22 are arranged circumferentially on the outer wall of the installation plate 2. Multiple support beams 3 are provided, with one end of each support beam hinged to a corresponding hinge groove 22. A sliding hole 23 is provided at the center of the installation plate 2. The spreading mechanism 4 is located at the center of the installation plate 2 and includes a spreading rod 41 slidably disposed within the sliding hole 23. Multiple connecting beams 42 are hinged to the lower outer wall of the opening rod 41 along the circumferential direction. The end of each connecting beam 42 away from the opening rod 41 is hinged to the side of the corresponding support beam 3 near the opening rod 41. There are multiple sets of cleaning mechanisms 5. The cleaning mechanisms 5 are located at the end of the corresponding support beam 3 away from the hinge groove 22. Each set of cleaning mechanisms 5 includes a cleaning plate 51 that can move back and forth along the length of the corresponding support beam 3. Each cleaning plate 51 is provided with a triangular insert 511 at the end away from the mounting plate 2. There are multiple sets of stepping mechanisms 6. The stepping mechanisms 6 are located at the end of the corresponding support beam 3 away from the hinge groove 22. Each set of stepping mechanisms 6 includes a stepping wheel 61 that can rotate as the corresponding cleaning plate 51 moves back and forth.

[0039] The staff placed winch 1 on top of the decomposition furnace (as needed). Figure 12 As shown, the mounting plate 2 is suspended horizontally inside the decomposition furnace using steel wires. Then, by adjusting the support rod 41, it moves along the axis of the sliding hole 23. As the support rod 41 moves, multiple connecting beams 42 at its lower end drive multiple support beams 3 to move away from the support rod 41. At this time, the stepping wheels 61 on the support beams 3 can insert into the crust on the inner wall of the decomposition furnace, ensuring the stability of the mounting plate 2 inside the furnace. Subsequently, the cleaning plate 51 on the support beams 3 can move along the length of the support beams 3 towards the inner wall of the decomposition furnace. The triangular insert 511 at the front end of the cleaning plate 51 can be inserted at an angle into the crust inside the decomposition furnace, thereby peeling the crust off the inner wall of the decomposition furnace. Then, the cleaning plate 51 moves away from the inner wall of the decomposition furnace. At this time, the corresponding stepping wheel 61 can slowly rotate with the movement of the cleaning plate 51. Multiple stepping wheels 61 cooperate with each other to make the mounting plate 2 slowly rotate. During the rotation, the winch 1 cooperates with the rotation of the mounting plate 2 to make the mounting plate 2 move along the axis of the decomposition furnace, thereby enabling a comprehensive cleaning of the inner wall of the decomposition furnace. The inclined stepping wheel 61 can prevent the peeled crust from sticking to the stepping wheel 61.

[0040] See Figure 2As shown, the spreading mechanism 4 also includes hydraulic rods 43; a push plate 411 is provided on the top of the spreading rod 41, and there are multiple hydraulic rods 43. The multiple hydraulic rods 43 are vertically arranged on the top of the mounting plate 2 and located between the push plate 411 and the mounting plate 2; the top of each hydraulic rod 43 is fixedly connected to the bottom of the push plate 411.

[0041] In the unused state, multiple hydraulic rods 43 reduce the distance between the push plate 411 and the mounting plate 2, thereby allowing multiple support beams 3 to move towards the axis of the mounting plate 2, making it easier for workers to move the mounting plate 2 into the decomposition furnace. The multiple hydraulic rods 43 are equidistantly arranged along the circumference of the push plate 411. When the decomposition furnace needs to be cleaned, workers use a winch 1 to hoist the mounting plate 2 into the decomposition furnace. Subsequently, through the cooperation of the multiple hydraulic rods 43, the spreading rod 41 can move along the axis of the sliding hole 23, and the multiple support beams 3 can move away from the axis of the mounting plate 2, allowing the stepping wheel 61 to obliquely contact the inside of the decomposition furnace, thereby supporting the entire device.

[0042] See Figure 3 , Figure 4 and Figure 8 As shown, each cleaning mechanism 5 also includes a guide rail 52; the guide rail 52 is located on the side of the corresponding support beam 3 away from the axis of the mounting plate 2, and the length direction of the guide rail 52 is the same as the length direction of the corresponding support beam 3. The cleaning plate 51 is slidably installed in the corresponding guide rail 52; each cleaning plate 51 is provided with a mounting cavity 512, and a counterweight column 513 is slidably installed in each mounting cavity 512. Each cleaning plate 51 is provided with a rope hole 514 communicating with the mounting cavity 512 at the center of one end near the mounting plate 2. Each push plate 411 is provided with multiple guide holes 412 along the circumferential direction at the top edge of the push plate 411. Each counterweight column 513 is provided with a traction rope 5131, and the traction rope 5131 passes through the rope hole 514 and the guide hole 412 in sequence and is wound on the winch 1.

[0043] It should be noted that winch 1 has two independent take-up shafts (which, when combined with other equipment) Figure 1As shown, one winding shaft is used to hoist the mounting plate 2, and the other winding shaft is used to wind the traction rope 5131. Driven by the hydraulic rod 43, multiple support beams 3 can support the mounting plate 2. Subsequently, the winch 1 pulls multiple traction ropes 5131 synchronously. The guide hole 412 ensures the stability of the pulling of the traction ropes 5131. As the traction ropes 5131 are pulled, the corresponding counterweight column 513 can synchronously pull the corresponding cleaning plate 51 to move along the length direction of the guide rail 52. When it moves to a suitable position, the winch 1 stops winding. Under the action of gravity, the cleaning plate 51 can collide with the scale in the decomposition furnace along the length direction of the guide rail 52, thereby completing the cleaning of the scale on the inner wall of the decomposition furnace.

[0044] See Figures 4 to 6 As shown, each stepping mechanism 6 also includes a fixed plate 62, a U-shaped plate 63, and a rack 64; the fixed plate 62 is located at the end of the corresponding support beam 3 away from the mounting plate 2, and an inclined plate 621 is provided on the fixed plate 62; a rotating hole 622 is provided on the inclined plate 621, and a rotating rod 611 is provided at the center of each stepping wheel 61, and the rotating rod 611 is rotatably located in the corresponding rotating hole 622; a one-way bearing 612 is provided at the end of each rotating rod 611 away from the stepping wheel 61, and multiple gear teeth 6121 are provided on the outer wall of each one-way bearing 612 along the circumferential direction; the U-shaped plate 63 is located on the inclined plate 621, and connecting holes 631 are provided on the inner walls of both sides of the U-shaped plate 63; connecting rods 641 are provided at both ends of the rack 64. The connecting rod 641 is slidably disposed in the corresponding connecting hole 631, and the rack 64 meshes with the gear teeth 6121 on the outer wall of the one-way bearing 612. Each connecting rod 641 is also fitted with a return spring 642, which is located inside the chamfered plate 63. The top of the chamfered plate 63 is provided with a rectangular notch 632, and a reaction rod 633 is hinged in the rectangular notch 632. A push rod 643 is provided at the center of the side of the rack 64 away from the one-way bearing 612. The reaction rod 633 is provided with an elliptical groove 6331 for accommodating the push rod 643, and the push rod 643 is slidably disposed in the elliptical groove 6331. Each cleaning plate 51 is provided with an L-shaped moving rod 515 that cooperates with the reaction rod 633.

[0045] In this embodiment, when the traction rope 5131 is pulled, the cleaning plate 51 moves away from the mounting plate 2. Due to the one-way bearing 612, the stepping wheel 61 does not rotate. When the traction rope 5131 is loosened, the cleaning plate 51 moves closer to the mounting plate 2. The L-shaped moving rod 515 on the cleaning plate 51 can contact the reaction rod 633, allowing the reaction rod 633 to rotate along the hinge position. At this time, the push rod 643 can drive the rack 64 to move along the connecting axis as the reaction rod 633 rotates. The elliptical groove 6331 can provide space for the rack 64 to move. The rack 64 drives the one-way bearing 612 to rotate, allowing the stepping wheel 61 to move slowly. Due to the inclined plate 621, the stepping wheel 61 is inclined at a certain angle to the support beam 3, causing the entire device to move spirally along the decomposition furnace axis, thereby improving the cleaning effect on the scale.

[0046] In another embodiment, the operator can drive the stepper wheel 61 to rotate using a servo motor. The servo motor is equipped with a sensor. As the cleaning plate 51 moves, the servo motor can drive the stepper wheel 61 to rotate in coordination with the movement of the cleaning plate 51 based on the data transmitted by the sensor.

[0047] See Figures 8 to 11 As shown, each triangular insert 511 is provided with a strip-shaped notch 5111 communicating with the mounting cavity 512. Each mounting cavity 512 is also provided with a prying mechanism 7 capable of secondary cleaning of the crust as the counterweight column 513 moves. Each prying mechanism 7 includes a flexible steel plate 71 and a pushing plate 72. Each mounting cavity 512 is provided with two limiting plates 5121, forming a receiving cavity 5122 between the two limiting plates 5121 to accommodate the flexible steel plate 71. The receiving cavity 5122 communicates with the strip-shaped notch 5111. The pushing plate 72 is slidably disposed within the receiving cavity 5122. One end of the pushing plate 72 near the strip-shaped notch 5111 is welded to the flexible steel plate 71, and the other end of the pushing plate 72 away from the flexible steel plate 71... Each contact plate 721 is provided with a contact plate 721; each limiting plate 5121 is provided with a mounting plate 51211 at the end away from the strip notch 5111, each mounting plate 51211 is provided with two limiting holes 51212, each contact plate 721 is provided with a limiting rod 722 corresponding to the limiting hole 51212 on the side of the mounting plate 51211, and the limiting rod 722 is slidably disposed in the corresponding limiting hole 51212; each limiting rod 722 is provided with a limiting disc 723 at the end away from the contact plate 721, the diameter of the limiting disc 723 is larger than the inner diameter of the limiting hole 51212; each limiting rod 722 is also fitted with a pull spring 724, the pull spring 724 is located between the corresponding contact plate 721 and the mounting plate 51211.

[0048] Multiple traction ropes 5131 are simultaneously pulled by winch 1. These ropes 5131, through rope holes 514, pull corresponding counterweight columns 513, causing the counterweight columns 513 to move away from the contact plate 721. Simultaneously, this moves the corresponding cleaning plate 51 towards the mounting plate 2. Once the cleaning plate 51 reaches the appropriate position, winch 1 releases the traction ropes 5131. The cleaning plate 51 then moves along the length of guide rail 52 towards the inner wall of the decomposition furnace. Under gravity, the cleaning plate 51 inserts into the crust of the decomposition furnace. Subsequently, the speed of the cleaning plate 51 gradually decreases and stops. During this process, the counterweight columns 513 continue to slide within the mounting cavity 512. Finally, the counterweight columns 513 impact the contact plate. This allows the push plate 72 to move along the receiving cavity 5122 toward the direction of the strip-shaped notch 5111. During this process, the pull spring 724 is compressed to generate elastic force. The push plate 72 is welded to the flexible steel plate 71, which can be pushed out along the strip-shaped notch 5111 and inserted into the crust into which the cleaning plate 51 is inserted, so that the crust can be removed from the inner wall of the decomposition furnace, further improving the cleaning effect of the crust. Subsequently, the winch 1 continues to rotate, thereby pulling the traction rope 5131. During this process, multiple pull springs 724 can reset the push plate 72, allowing the flexible steel plate 71 to retract into the receiving cavity 5122 through the strip-shaped notch 5111, thereby continuously cleaning the crust.

[0049] See Figure 4 and Figure 5 As shown, each stepping wheel 61 has multiple anti-slip teeth 613 arranged on its outer wall along the circumferential direction.

[0050] By incorporating multiple anti-slip teeth 613 with flexible tips, damage to the inner wall of the decomposition furnace can be avoided. The anti-slip teeth 613 can be inserted into the crust of the decomposition furnace, ensuring that the stepper wheel 61 can drive the entire device to rotate. Furthermore, each stepper wheel 61 has an annular slice 614 on its outer wall. When the flexible steel plate 71 is inserted into the crust, the annular slice 614 can perform secondary cutting on the unpeeled crust, further improving the cleaning effect of the crust.

[0051] See Figure 1 and Figure 2 As shown, the top of the mounting plate 2 is also provided with multiple gantry frames 24 along the circumferential direction, and each gantry frame 24 has two auxiliary wheels 241 that can rotate inside to guide the traction rope 5131.

[0052] By setting up multiple gantry frames 24, each gantry frame 24 having two auxiliary wheels 241 inside, the traction rope 5131 can be guided, improving the smoothness of pulling the traction rope 5131.

[0053] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
