Description

Technical Field

[0001] This invention belongs to the field of rotary kiln technology, specifically relating to a ring-forming treatment device for a zinc oxide rotary kiln. Background Technology

[0002] Zinc oxide rotary kilns calcine zinc-containing raw materials at high temperatures, reducing metallic zinc to form zinc vapor. This zinc vapor reacts with oxygen to produce zinc oxide. However, at high temperatures, non-volatile metals such as iron are also reduced, forming rings within the kiln. This causes changes in the kiln's cross-section, affecting material and heat conduction, deteriorating the kiln's thermal conditions, and reducing the kiln's output and quality. Therefore, it is essential to treat these rings. During production, after rings form within the kiln, most systems use blowers to blow away the rings online without shutting down the kiln. However, this only inhibits or slows down the formation rate; a thicker ring gradually forms on the kiln's inner wall. At this point, maintenance and manual cleaning of the rings are necessary. Current manual ring removal methods require workers to enter the kiln, which is labor-intensive, inefficient, and time-consuming.

[0003] Patent CN208475962U discloses a rapid ring-removal device for rotary kilns. The technical solution is as follows: Both ends of the drive shaft and connecting shaft are respectively equipped with drive and driven track wheels. The drive track wheels at both ends of the drive shaft and the driven track wheels at both ends of the connecting shaft are connected by a track drive. The middle of the drive shaft is equipped with a first pulley and a second pulley for transmission connection. One end of the second rotating shaft is fixed to a fixed block inside the housing, and the other end of the second rotating shaft is fixedly connected to a rotating rod. A second motor is driven by a striking device through the first rotating shaft. The striking device strikes the rings, reducing the labor intensity of workers and increasing the cleaning speed compared to manual cleaning. However, this device uses a point-to-point striking method for cleaning, and the cleaning time is still relatively long. The cleaning efficiency still needs further improvement. In addition, due to the high hardness and strong adhesion of the rings, this striking method can cause local stress concentration on the inner wall of the rotary kiln, which can easily damage the refractory layer of the inner wall of the rotary kiln and reduce the service life of the rotary kiln.

[0004] Therefore, in view of the above-mentioned shortcomings, this application proposes a ring-forming treatment device for zinc oxide rotary kilns that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a ring-forming treatment device for zinc oxide rotary kilns, thereby effectively solving the problems existing in the prior art.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0007] A ring-forming device for a zinc oxide rotary kiln includes a main bearing shaft tube. A first fixing device is provided on the outer wall of the left end of the main bearing shaft tube. A first sliding bushing device is slidably installed at the middle position of the main bearing shaft tube. A second fixing device is fixedly installed on the first sliding bushing device. A second sliding bushing device is slidably installed at the right end of the main bearing shaft tube. A rotating table is rotatably installed on the second sliding bushing device. A grinding disc device is fixedly installed on the rotating table. A drive motor is fixedly installed inside the second sliding bushing device and connected to the rotating table. A telescopic device is fixedly connected inside the main bearing shaft tube and connected to the second sliding bushing device.

[0008] As a further provision of the above scheme, a through installation channel is opened inside the main bearing shaft tube, a first guide strip is provided on the outer wall of the main bearing shaft tube, a second guide strip is provided on the inner wall of the installation channel, the first fixing device includes a first fixing bushing, a guide groove is opened on the first fixing bushing, the guide groove is connected to the first guide strip to axially position the first fixing bushing, a positioning device is provided on the first fixing bushing, the first fixing bushing is fixedly installed on the main bearing shaft tube by the positioning device, a first telescopic cylinder is provided on the first fixing bushing, a first telescopic rod is provided on the first telescopic cylinder, and a first fixing foot is fixedly connected to the outer end of the first telescopic rod.

[0009] As a further feature of the above solution, the first sliding bushing device has a guide groove, which is slidably connected to the first guide bar, and the first sliding bushing device can reciprocate under the guidance of the first guide bar.

[0010] As a further provision of the above solution, the second fixing device includes a second fixing bushing, on which are evenly distributed second telescopic cylinders, and on which are outwardly diverging second telescopic rods, and the outer end of the second telescopic rods is fixedly connected to a second fixing foot.

[0011] As a further provision of the above scheme, the second sliding bushing device includes a mounting circular plate, a second sliding bushing is provided at the center of the mounting circular plate, the second sliding bushing is slidably connected to the second guide strip, the outer wall of the second sliding bushing is slidably connected to the mounting channel, a guide outer ring is provided on the outer edge of the mounting circular plate, and an annular groove is formed between the guide outer ring and the second sliding bushing, and the second sliding bushing device is slidably connected to the main bearing shaft tube through the annular groove.

[0012] As a further feature of the above scheme, a mounting flange is provided at the center of the right end of the mounting plate, and the mounting flange is rotatably connected to the rotary table. A spring device is fixedly connected to the left end of the guide outer ring, and the left end of the spring device is fixedly connected to the first sliding bushing device.

[0013] As a further feature of the above solution, the grinding disc device includes a mounting disc, which is fixedly connected to a rotary table. Spokes are evenly arranged on the mounting disc, radiating outwards. A grinding disc is fixedly connected to the outer end of each spoke. A grinding tool is provided on the end face of the grinding disc. A guide plate is fixedly provided on each spoke, and the guide plate forms a certain angle with the grinding disc. When the grinding disc rotates, the guide plate blows out a high-speed airflow to the right.

[0014] The beneficial effects of this invention are:

[0015] When this device is in operation, the equipment is placed inside the main bearing shaft tube. Simultaneously, the first and second telescopic cylinders are activated, causing the first and second telescopic rods to extend. The first and second fixed feet contact the inner wall of the rotary kiln.

At this time, the grinding disc is also coaxial with the rotary kiln. The drive motor is started, and the rotary table drives the grinding disc to rotate at high speed via the mounting plate and spokes. The grinding tools contact the rings inside the rotary kiln, breaking them up. The guide plate rotates synchronously, blowing a high-speed airflow to the right, dispersing the dust separated during grinding away from the grinding area. The telescopic device is then activated, slowly and uniformly pushing the second sliding bushing device. The grinding disc slides to the right within the main bearing shaft tube, causing the grinding tool to move to the right. The spring device is stretched, and the grinding tool cleans the inner wall of the rotary kiln. After the telescopic device extends to its limit, the second telescopic cylinder slowly retracts, the second fixed foot disengages from the inner wall of the rotary kiln, and the second fixed device moves to the right under the action of the spring device. The second telescopic cylinder extends, and after the second fixed device is fixed, the first telescopic cylinder slowly retracts, the first fixed foot disengages from the inner wall of the rotary kiln, the telescopic device retracts, causing the main bearing shaft tube to move to the right. The first telescopic cylinder extends, and the first fixed device is fixed. At this point, the entire equipment is re-fixed inside the rotary kiln. The telescopic device and drive motor are restarted to grind the next section of the inner wall of the rotary kiln, achieving automated cleaning.

[0016] This invention, by setting a first fixing device and a second sliding bushing device on the main bearing shaft tube, and cooperating with the first sliding bushing device and the second fixing device, and driven by the telescopic device and the drive motor, performs uniform and comprehensive cleaning of the inner wall of the rotary kiln, reducing damage to the refractory layer of the rotary kiln, and can automatically move inside the rotary kiln, improving the cleaning efficiency of rings.
