Description

Technical Field

[0001] This invention relates to the field of industrial furnace technology, specifically to a kiln cleaning machine. Background Technology

[0002] Currently, metal extraction primarily relies on ores, most of which require roasting and activation before smelting. Rotary kilns are commonly used for ore roasting. During the roasting of minerals like dolomite, the high temperatures within the kiln cause low-melting-point substances in the ore to volatilize. These volatilized substances re-cool and form rings in cooler areas of the kiln. These rings mainly consist of impurities such as molten clinker, and they typically form in the firing zone of the kiln. In severe cases, the entire kiln surface can become blocked, preventing material flow and disrupting normal production. Currently, ring removal in rotary kilns mainly involves manual cleaning or equipment cleaning after the kiln is shut down. The former presents workers with harsh working conditions and inherent risks. The latter requires stopping the kiln and material feeding, necessitating preheating before resuming feeding, which is energy-intensive and costly. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a kiln cleaning machine, characterized in that it includes a guide acceleration tube, one end of which is provided with a kiln door connecting assembly that connects to the kiln door, and the other end is provided with a high-pressure air supply assembly, a filling assembly, and a filling support assembly connected to the guide acceleration tube; the filling assembly includes a lead column box and a supply plate disposed at the bottom of the lead column box and communicating with it, the supply plate being disposed within the filling support assembly, one end of which is connected to a supply cylinder, and the other end being connected to the high-pressure air supply assembly through a supply tube; the filling support assembly includes a support front plate, support side plates disposed on both sides of the support front plate, and a pusher mounting plate connected to the support side plates, the supply cylinder being disposed on the pusher mounting plate and coaxially disposed with the supply tube, the top of the pusher mounting plate being provided with a pressing mechanism corresponding to the lead column box, and the bottom of the support side plate being provided with a worm gear mechanism for driving the supply plate to rotate.

[0004] Preferably, the lead column box is a fan-shaped box with an opening that gradually decreases from top to bottom. Several lead column placement slots are arranged circumferentially inside the lead column box, and elongated holes are opened on both sides of the lead column placement slots. The lead column placement slots are arranged through the lead column box, and the supply tray is provided with a lead column inlet that communicates with the bottom of the lead column placement slot.

The servo drive motor is disposed on a motor bracket on the outer side of the side plate of the support.

[0007] The advantages of this invention compared to the prior art are as follows: This device inserts a lead column through a loading component and then injects the lead column into the kiln door through a high-pressure air supply component via a guide acceleration tube, thereby cleaning the rings inside the kiln head. Compared to other methods, this device can clean the rings under normal kiln firing conditions, with minimal impact on firing, and is safe and highly efficient, thus extending the production cycle of the rotary kiln.

[0022] Combined with appendix Figure 1-7 This embodiment discloses a kiln cleaning machine, including a guide acceleration tube 1. One end of the guide acceleration tube 1 is provided with a kiln door connecting component 2 that connects to the kiln door, and the other end is provided with a high-pressure air supply component 3, a filling component 4, and a filling bracket component 5 connected to the guide acceleration tube 1. A clamp 8 is provided in the middle of the guide acceleration tube 1. The top of the clamp 8 is connected to the suspension trolley 10 through a screw 9. The suspension trolley 10 is slidably arranged on a horizontally arranged electric guide rail 11. A suspension bracket 12 is provided on the top of the electric guide rail 11.

[0023] The loading assembly 4 includes a lead column box 401 and a supply tray 402 disposed at and connected to the bottom of the lead column box 401. The lead column box 401 is a fan-shaped box with an opening that gradually decreases from top to bottom. Several lead column placement slots 405 are arranged at intervals on the inner circumference of the lead column box 401. Long holes 406 are opened on the lead column box 401 on both sides of the lead column placement slots 405. The lead column placement slots 405 are arranged through the lead column box 401. The bottom of the lead column box 401 is in contact with the supply tray 402. The supply tray 402 is provided with a lead column inlet corresponding to the bottom outlet of the lead column placement slots 405. The supply tray 402 is disposed in the loading bracket assembly 5. One end of the supply tray 402 is connected to the supply cylinder 403, and the other end is connected to the high-pressure air supply assembly 3 through the supply pipe 404. The supply cylinder 403 and the supply pipe 404 are coaxially arranged so that the lead column falling into the supply tray 402 is sent into the guide acceleration pipe 1.

[0024] The loading bracket assembly 5 includes a bracket front plate 501, bracket side plates 502 disposed on both sides of the bracket front plate 501, and a pusher mounting plate 503 connected to the bracket side plates 502. A supply cylinder 403 is disposed on the pusher mounting plate 503. A pressing mechanism 6 corresponding to the lead column box 401 is disposed on the top of the pusher mounting plate 503, and a worm gear mechanism 7 for driving the supply plate 402 to rotate is disposed on the bottom of the bracket side plate 502.

[0025] The clamping mechanism 6 includes a baffle 601 disposed on the side of the lead column box 401 near the high-pressure air supply component 3, and a push plate 602 abutting against the other side of the lead column box 401. The push plate 602 is connected to the clamping cylinder 603. The clamping cylinder 603 is fixed to the top of the push spring mounting plate 503 through the clamping cylinder mounting plate 604. Both ends of the baffle 601 are connected to the bracket side plate 502 of the loading bracket assembly 5.

[0026] The worm gear mechanism 7 includes a worm gear rack 701 disposed at the bottom of the feed plate 402 and a worm 702 meshing with the worm gear rack 701. One end of the worm 702 is rotatably connected to the side plate 502 of the support, and the other end extends out of the side plate 502 and is connected to a servo drive motor 703. The servo drive motor 703 is disposed on a motor bracket 704 on the outside of the side plate 502. When all the lead columns in a lead column placement slot 405 of the lead column box 401 fall into the feed plate 402, the worm gear mechanism 7 causes the feed plate 402 to rotate at a certain angle, so that the lead column inlet of the feed plate 402 is connected to the bottom outlet of the other lead column placement slots 405 of the feed plate 402. A backrest wheel assembly 705 is also provided at the connection between the worm 702 and the servo drive motor 703.

[0027] The high-pressure gas supply assembly 3 includes a gas storage cylinder 301 and a high-pressure solenoid valve 302 connected to the bottom of the gas storage cylinder 301. The gas storage cylinder is used to temporarily store high-pressure gas and to drive the steel segment to accelerate when released for a short time. The high-pressure solenoid valve 302 is installed on the gas supply housing 303. A gas supply pipe 309 is provided inside the high-pressure solenoid valve 302, which connects the gas storage cylinder 301 and the guide acceleration pipe 1, so that the gas in the gas storage cylinder 301 rushes into the guide acceleration pipe 1. A movable stop is provided in the gas supply housing 303 on the side of the gas supply pipe 309 away from the guide acceleration pipe 1. The movable baffle 304 has sealing plates 305 attached to both sides. One end of the movable baffle 304 extends out of the sealing plate 305 and is hinged to a movable baffle push-pull cylinder 306. The movable baffle push-pull cylinder 306 is set on the front plate 501 of the support of the filling support assembly 5 through a cylinder connecting plate 307. A cooling water jacket 308 is set outside the gas storage cylinder 301. The movable baffle 304, the sealing plate 305 and the gas supply housing 303 are all provided with a central channel 310 connecting the supply plate 402 and the guide acceleration tube 1.

[0028] In practice, plastic-coated lead pillars are loaded into a lead pillar box, 50-100 pillars at a time. The box is then placed into the kiln cleaning machine, where a clamping cylinder presses the box between the baffle and push plate. A movable baffle push-pull cylinder 306 pulls out the movable baffle 304, ensuring the central hole inside the assembly is aligned. A push-push cylinder 403 sends the lead pillars that have fallen into the central hole into the acceleration tube 1. The movable baffle push-pull cylinder 306 then pushes the movable baffle 304 into the sealing plate, sealing the central hole. Then, the solenoid valve 302 opens, and the high-pressure gas in the gas cylinder 301 enters the central hole between the movable baffle 304 and the lead column, thereby accelerating the lead column in the acceleration tube 1 and finally entering the kiln at high speed, using kinetic energy to remove the ring formation. After one row of lead columns in the lead column box 401 has been launched, the servo drive motor 703 drives the supply plate 402 to rotate at a suitable angle through the transmission system, so that the slot on the drive supply plate 402 is aligned with the next row of lead columns in the lead column box 401. The above steps are repeated until the lead columns in the lead column box are consumed. An alarm set in the central control room will prompt the operator to replace the lead column box 401. In specific implementation, a remote control room can be set up for remote automatic control.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
