Description

Technical Field

[0001] This invention relates to the field of coke oven flue cleaning technology, specifically a coke oven flue suction cleaning mechanism. Background Technology

[0002] As a core piece of equipment in the metallurgical industry, coke ovens are prone to accumulating large amounts of tar, dust, and high-temperature coke deposits in their flue systems during long-term operation. A flue cleaning device based on patent number CN208817510 typically uses a single rotating scraper to remove the accumulated scale. However, this device has the following technical defects:

[0003] In this device, the rotating scraper with a fixed rotation speed contacts the inner wall of the flue and removes tar by relying solely on unidirectional tangential force. It does not take into account the characteristics of tar viscosity changing with temperature, resulting in low efficiency in removing solidified or high-viscosity deposits, and it is easy to form scraping dead angles, which can reduce the cleaning efficiency of the coke oven flue. Therefore, a solution is proposed. Summary of the Invention

[0004] The purpose of this invention is to effectively improve the removal efficiency of tar from the flue by utilizing the synergistic combination of a rotating and reciprocating motion mechanism and a thermally assisted tar softening structure. Furthermore, the self-cleaning structure with a built-in roller brush enables self-cleaning of the cleaning structure and reduces secondary pollution of the flue, thereby further improving the cleaning efficiency of the coke oven flue.

[0005] The objective of this invention can be achieved through the following technical solution: a coke oven flue suction and cleaning mechanism, comprising a cleaning outer cylinder and two sets of fixing rings, wherein the two sets of fixing rings are respectively fixedly installed at both ends of the outer side of the cleaning outer cylinder, and pulley brackets are provided at the front and rear positions of the bottom of the fixing rings.

[0006] The cleaning outer cylinder is equipped with a composite cleaning mechanism, which includes a movable long rod. The movable long rod is horizontally inserted through the center of the cleaning outer cylinder and is sleeved inside two sets of upright frames fixedly installed on the inner wall of the bottom of the cleaning outer cylinder. One end of the movable long rod extends to the outside of the cleaning outer cylinder, and the other end extends to the opening of the cleaning outer cylinder and is fixedly installed with a positioning cylinder.

[0007] A cleaning disc is fixedly installed on the side of the positioning cylinder away from the movable long rod, and several sets of inclined scrapers are fixedly installed at equal intervals on the outside of the cleaning disc. A thermal auxiliary component is provided at the center of the inside of the cleaning disc.

[0008] Furthermore, the outer diameter of the cleaning disc is 3cm larger than the outer diameter of the positioning cylinder, an auxiliary rotating toothed roller is fixedly sleeved on the outer end of the movable long rod near the positioning cylinder, and two sets of chucks are fixedly sleeved on the outer side of the movable long rod between the two sets of upright frames.

[0009] Furthermore, the composite cleaning mechanism also includes a motor, which is located on the inner wall of the cleaning outer cylinder away from the cylinder opening and at the upper end of the movable long rod. A spiral rotating rod is fixedly installed at the output end of the motor, and a main rotating toothed disc is fixedly installed at the end of the spiral rotating rod away from the motor. The main rotating toothed disc meshes with the top surface of the auxiliary rotating toothed roller.

[0010] Furthermore, a spiral sleeve frame is movably sleeved at the end of the spiral rotating rod near the motor, and sliders are hinged at both the front and rear ends of the spiral sleeve frame. A concave-shaped clamping frame is clamped on the outside of the spiral sleeve frame, and the top of the clamping frame is hinged to the inner wall of the cleaning outer cylinder through a hinge rod. The bottom of the clamping frame is sleeved on the outside of the movable long rod and located between two adjacent sets of clamps. Slide grooves are provided at both the front and rear frames of the clamping frame, and the two sets of sliders are respectively clamped in the corresponding slide grooves.

[0011] Furthermore, the thermal auxiliary component includes an air inlet cylinder, which is disposed through the center of the cleaning disc, and an air inlet valve pipe is provided at one end of the air inlet cylinder. A mesh cover is fixedly installed on the air inlet cylinder outside the air inlet valve pipe. Exhaust valve pipes are provided at the upper and lower ends and the front and rear ends of the air inlet cylinder on the side away from the air inlet valve pipe. A push cylinder is transversely disposed inside the air inlet cylinder.

[0012] Furthermore, a piston is fixedly installed at one end of the push cylinder extending to the air inlet cylinder, and a cylinder is provided at the other end extending outside the air inlet cylinder via a push rod. The cylinder is located on the inner wall of one side of the positioning cylinder.

[0013] Furthermore, the inner diameter of the cleaning outer cylinder is 3cm larger than the outer diameter of the cleaning disc, and roller brushes are respectively rotatably installed on one side of the front and rear inner walls of the cleaning outer cylinder via concave card seats.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention achieves comprehensive cleaning of the inner wall of the flue by setting up a composite cleaning mechanism. The cooperation of the movable long rod, positioning cylinder and cleaning disc allows the scraper to move flexibly on the inner wall of the flue, effectively removing the accumulated dirt. Furthermore, the meshing of the auxiliary rotating toothed roller and the main rotating toothed disc forces the cleaning disc to reciprocate while rotating, further improving the cleaning efficiency.

[0016] 2. At the same time, a thermal auxiliary component is set up. By releasing high-temperature gas around the cleaning plate, the intermittent release of high-temperature gas can more evenly preheat and soften the inner wall of the coke oven flue, reduce the hardness of the solidified tar, facilitate subsequent removal, and further improve the cleaning effect.

[0017] 3. The present invention also includes a roller brush assembly that works in conjunction with the composite cleaning structure. The cleaning disc returns to the inside of the cleaning outer cylinder and contacts the outer walls of the two sets of roller brushes respectively. As the cleaning disc rotates, the surface of the cleaning disc is forced to rub against the roller brushes, which helps to remove the coke residue attached to the scraper of the cleaning disc, thereby achieving self-cleaning of the cleaning structure and reducing secondary pollution of the flue.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1-6As shown, a coke oven flue suction cleaning mechanism includes a cleaning outer cylinder 1 and two sets of fixing rings 2. The two sets of fixing rings 2 are respectively fixedly installed at both ends of the outer side of the cleaning outer cylinder 1, and pulley brackets are provided at the front and rear positions of the bottom of the fixing rings 2.

[0028] The cleaning outer cylinder 1 is equipped with a composite cleaning mechanism 3. The composite cleaning mechanism 3 includes a movable long rod 31. The movable long rod 31 is horizontally inserted through the center of the cleaning outer cylinder 1. The movable long rod 31 is sleeved inside two sets of upright frames that are fixedly installed on the inner wall of the bottom of the cleaning outer cylinder 1. One end of the movable long rod 31 extends to the outside of the cleaning outer cylinder 1, and the other end extends to the opening of the cleaning outer cylinder 1 and is fixedly installed with a positioning cylinder 32.

[0029] A cleaning disc 33 is fixedly installed on the side of the positioning cylinder 32 away from the movable long rod 31, and several sets of inclined scrapers are fixedly installed at equal intervals on the outside of the cleaning disc 33. The outer diameter of the cleaning disc 33 is 3cm larger than the outer diameter of the positioning cylinder 32. An auxiliary rotating toothed roller 35 is fixedly sleeved on the outside of the movable long rod 31 near the positioning cylinder 32, and two sets of chucks 36 are fixedly sleeved on the outside of the movable long rod 31 between the two sets of upright frames.

[0030] The composite cleaning mechanism 3 also includes a motor 37. The motor 37 is located on the inner wall of the cleaning outer cylinder 1 away from the cylinder opening and at the upper end of the movable long rod 31. A spiral rotating rod 38 is fixedly installed at the output end of the motor 37. A main rotating toothed disc 39 is fixedly installed at the end of the spiral rotating rod 38 away from the motor 37. The main rotating toothed disc 39 meshes with the top surface of the auxiliary rotating toothed roller 35.

[0031] A spiral frame 310 is movably sleeved on the outer end of the spiral rotating rod 38 near the motor 37, and sliders 311 are hinged to both the front and rear ends of the spiral frame 310. A concave-shaped clamping frame 312 is clamped on the outside of the spiral frame 310, and the top of the clamping frame 312 is hinged to the inner wall of the cleaning outer cylinder 1 through a hinge rod. The bottom of the clamping frame 312 is sleeved on the outside of the movable long rod 31 and located between two adjacent sets of chucks 36. Slide grooves are provided at both the front and rear frames of the clamping frame 312, and the two sets of sliders 311 are respectively clamped in the corresponding slide grooves.

[0032] Align the outer cleaning cylinder 1 with the exhaust port of the coke oven flue. Then, start the motor 37 to drive the spiral rod 38 and the main rotating gear 39 to rotate synchronously. Through gear meshing, the cleaning disc 33 rotates on its own. The outer scraper of the cleaning disc 33 rubs against the inner wall of the flue, effectively removing the attached dirt.

[0033] At the same time, the rotation of the spiral rod 38 also causes the spiral sleeve 310 to move along the length of the spiral rod 38. The movement of the spiral sleeve 310 drives the bottom of the clamping frame 312 to deflect through the hinged slider 311. Since the bottom of the clamping frame 312 is sleeved on the outside of the movable long rod 31 and located between two adjacent sets of chucks 36, the deflection and reciprocating movement of the bottom of the clamping frame 312 will press against one of the sets of chucks 36, forcing the movable long rod 31 to move back and forth, and assisting the cleaning disc 33 to move back and forth along the inside of the flue. In conjunction with the rotation of the cleaning disc 33, the cleaning effect on the inner wall of the coke oven flue is further enhanced.

[0034] This structure achieves comprehensive and efficient cleaning of the inner wall of the coke oven flue through the combined action of the rotation and reciprocating movement of the cleaning disc 33.

[0035] Example 2: Please refer to Figure 2 - Figure 4 As shown, a thermal auxiliary component 34 is provided at the center of the cleaning tray 33. The thermal auxiliary component 34 includes an air inlet cylinder 341, which is disposed through the center of the cleaning tray 33. An air inlet valve pipe 342 is provided at one end of the air inlet cylinder 341. A mesh cover cylinder 343 is fixedly installed on the air inlet cylinder 341 outside the air inlet valve pipe 342. An exhaust valve pipe 344 is provided at the upper and lower ends and the front and rear ends of the air inlet cylinder 341 on the side away from the air inlet valve pipe 342. A push cylinder 345 is horizontally disposed inside the air inlet cylinder 341.

[0036] A piston 346 is fixedly installed at one end of the push cylinder 345 extending to the air inlet cylinder 341, and a cylinder 347 is provided at the other end of the push cylinder 345 extending outside the air inlet cylinder 341 via a push rod. The cylinder 347 is located on the inner wall of one side of the positioning cylinder 32.

[0037] During the cleaning process of the cleaning disc 33, the cleaning difficulty is increased due to the solidified and hardened tar adhering to the inner wall of the flue. Therefore, the cylinder 347 is activated to push the pusher 345 to move back and forth inside the air inlet cylinder 341 through the push rod. The pusher 345 drives the piston 346 to move synchronously and intermittently draw in and discharge the high-temperature gas in the coke oven. The drawn high-temperature gas is introduced into the air inlet cylinder 341 through the air inlet valve pipe 342. During this period, the dust particles in the high-temperature gas are filtered through the mesh cover cylinder 343 before they can be used.

[0038] Then, multiple sets of exhaust valve pipes 344 are used to discharge to the surrounding area of ​​the cleaning disc 33, and the inner wall of the coke oven flue is preheated and softened to reduce the hardness of the solidified tar, which facilitates the subsequent rotation and reciprocating movement of the cleaning disc 33 for cleaning, thereby further improving the cleaning efficiency.

[0039] The thermal auxiliary component 34, by discharging high-temperature gas around the cleaning plate 33 and discharging the high-temperature gas intermittently, can more evenly preheat and soften the inner wall of the coke oven flue, reduce the hardness of the solidified tar, facilitate subsequent cleaning, and further improve the cleaning effect.

[0040] It is worth noting that the inner diameter of the cleaning outer cylinder 1 is 3cm larger than the outer diameter of the cleaning disc 33, and roller brushes 4 are respectively rotatably installed on one side of the front and rear inner walls of the cleaning outer cylinder 1 through concave card seats.

[0041] After cleaning, the cleaning disc 33 returns to the inside of the cleaning outer cylinder 1 and contacts the outer walls of the two sets of roller brushes 4 respectively. As the cleaning disc 33 rotates, the surface of the cleaning disc 33 is forced to rub against the roller brushes 4, which helps to remove the char residue attached to the scraper of the cleaning disc 33.

[0042] Working principle: When using this invention, first align the outer cleaning cylinder 1 with the exhaust port of the coke oven flue, then start the motor 37 to drive the spiral rotating rod 38 and the main rotating gear 39 to rotate synchronously. Through gear meshing transmission, the cleaning disc 33 rotates on its own. The outer scraper of the cleaning disc 33 rubs against the inner wall of the flue, effectively removing the attached dirt.

[0043] Secondly, the rotation of the rotating rod 38 forces the spiral sleeve 310 to move along the length of the spiral rod 38. The movement of the spiral sleeve 310 drives the bottom of the clamping frame 312 to deflect through the hinged slider 311. Since the bottom of the clamping frame 312 is sleeved on the outside of the movable long rod 31 and located between two adjacent sets of chucks 36, the deflection and reciprocating movement of the bottom of the clamping frame 312 will press against one of the sets of chucks 36, forcing the movable long rod 31 to move back and forth, and assisting the cleaning disc 33 to move back and forth along the inside of the flue. In conjunction with the rotation of the cleaning disc 33, the cleaning effect on the inner wall of the coke oven flue is further enhanced.

[0044] At the same time, the cylinder 347 is activated, which pushes the pusher cylinder 345 to reciprocate inside the air inlet cylinder 341 via the pusher rod. The pusher cylinder 345 drives the piston 346 to move synchronously, and intermittently sucks and discharges the high-temperature gas in the coke oven. The sucked high-temperature gas is introduced into the air inlet cylinder 341 through the air inlet valve pipe 342. During this period, the dust particles in the high-temperature gas are filtered by the mesh cover cylinder 343 before they can be used. Then, multiple sets of exhaust valve pipes 344 are used to discharge the gas to the surrounding area of ​​the cleaning disc 33, and preheat and soften the inner wall of the coke oven flue to reduce the hardness of the solidified tar, so as to facilitate the subsequent rotation and reciprocating movement of the cleaning disc 33 for cleaning.

[0045] After cleaning, the cleaning disc 33 returns to the inside of the cleaning outer cylinder 1 and contacts the outer walls of the two sets of roller brushes 4 respectively. As the cleaning disc 33 rotates, the surface of the cleaning disc 33 is forced to rub against the roller brushes 4, which helps to remove the char residue attached to the scraper of the cleaning disc 33.
