Description

Technical Field

[0001] This utility model relates to the field of rotary kiln slag removal, and in particular to a device for preventing slag formation in a rotary kiln used for hazardous waste incineration. Background Technology

[0002] A rotary kiln for hazardous waste incineration is a hollow cylindrical steel incinerator with an inclination angle of 1°-5° and lined with refractory material. The rotation of the kiln achieves uniform mixing and combustion of hazardous waste, and it is characterized by its wide adaptability to various types of waste, capable of simultaneously incinerating solid waste, liquids, colloids, and gases. The incinerating material tumbles and moves forward, with three heat transfer methods coexisting in one furnace, resulting in high heat utilization. Lining replacement is convenient and inexpensive; the transmission mechanism is simple, and equipment maintenance is easy; the equipment has a high operating rate, typically reaching 90% annually.

[0003] However, in practice, some problems still exist: 1. Traditional equipment usually uses spiral scrapers to remove residues that have adhered to the inner wall of the rotary kiln. However, since a single spiral scraper can only remove loose, low-adhesion residues on the surface of the kiln wall through contact scraping, the scraper is easily stuck and worn when it comes to hard crusts formed by high-temperature sintering and chemical reactions. It may even fail to generate effective cutting force, resulting in extremely slow kiln cleaning speed.

[0004] 2. Traditional devices typically set the kiln body at a small tilt angle, allowing the material and residue inside the kiln to be slowly discharged as the kiln rotates. This results in a slow discharge speed, reduced work efficiency, and poor practicality.

[0005] Based on this, this utility model designs an anti-slagging device for a rotary kiln used for hazardous waste incineration to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for preventing slagging in a rotary kiln used for hazardous waste incineration, in order to solve the problem that spiral scrapers cannot quickly and effectively remove the hard crust formed by high-temperature sintering and chemical reactions.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-slagging device for a rotary kiln used for hazardous waste incineration, comprising a base, a rotary kiln body mounted on top of the base, a support frame mounted on top of the rotary kiln body, the four bottom corners of the support frame being fixedly connected to the base, the outer surface of the rotary kiln body being fixedly connected to the base via a transmission component, slag removal mechanisms for impacting the rotary kiln body being provided on both sides of the support frame, and a feeding mechanism for improving the slag removal effect being provided at one end of the rotary kiln body.

[0008] As a further description of the above technical solution: The transmission component includes two annular tracks fixedly installed on the outer surface of the rotary kiln body. Each of the two annular tracks has a matching transmission wheel on both sides of its bottom. The transmission wheels are rotatably connected to the fixed frame via a first rotating shaft. The fixed frame is fixedly connected to the base. A first motor is installed on one side of one of the fixed frames. The first motor is fixedly installed on the top of the base via a motor mount. The first rotating shaft is fixedly connected to the output end of the first motor.

[0009] As a further description of the above technical solution: The slag removal mechanism includes sleeves fixedly installed on both sides of the support frame. An impact cylinder is slidably installed inside the sleeve. A rotating cam is provided inside the impact cylinder. A second rotating shaft is fixedly connected to the top center of the rotating cam. The top end of the second rotating shaft passes through the support frame and extends to the outside of the support frame. The two second rotating shafts are connected by a power transmission component. Cylindrical blocks are fixedly connected to both sides of the inside of the impact cylinder. The cylindrical blocks cooperate with the rotating cam. Springs are provided between the impact cylinder and the support frame.

[0010] As a further description of the above technical solution: The power component includes two first bevel gears fixedly mounted on the top of the second rotating shaft. The two first bevel gears are meshed with second bevel gears on adjacent sides. The two second bevel gears are respectively fixed to the outer surfaces of the output ends on both sides of the dual-axis motor. The dual-axis motor is fixedly connected to the support frame. A protective box is fixedly installed on the support frame near the dual-axis motor.

[0011] As a further description of the above technical solution: Both sides of the impact cylinder are fixedly connected to limit sliders, and the sleeve is provided with a matching limit groove near the limit slider.

[0012] As a further description of the above technical solution: The feeding mechanism includes a discharge box rotatably installed at one end of the rotary kiln body. The bottom of the discharge box has a discharge port. A second motor is fixedly connected to one side of the discharge box. A drive shaft is fixedly connected to the output end of the second motor. Screw blades are fixedly connected to the outer surface of the drive shaft located inside the rotary kiln body.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, through the coordinated action of the base, rotary kiln body, support frame, transmission components and slag removal mechanism, a large impact force can be continuously applied to the kiln body while the rotary kiln body is rotating. This not only shakes off the residue adhering to the inner wall of the rotary kiln body, reducing the probability of residue adhering to the inner wall of the rotary kiln body, but also generates a certain impact force on the residue solidified inside the kiln body, causing the solidified residue to break and fall off the kiln body, thereby improving the slag removal effect. 2. In this utility model, through the coordinated action of the base, rotary kiln body, support frame, transmission components, slag removal mechanism and feeding mechanism, not only can the material inside the rotary kiln be transported, but also the residue adhering to the kiln body can be scraped off, and the residue falling off the kiln body can be quickly discharged to the outside of the device, thus improving work efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: an anti-slagging device for a rotary kiln for hazardous waste incineration, including a base 1, a rotary kiln body 2 on the top of the base 1, a control box fixedly installed on one side of the base 1, a support frame 3 on the top of the rotary kiln body 2, the four bottom corners of the support frame 3 being fixedly connected to the base 1, the outer surface of the rotary kiln body 2 being fixedly connected to the base 1 through a transmission component 4, slag removal mechanisms 5 for impacting the rotary kiln body 2 on both sides of the support frame 3, and a feeding mechanism 6 for improving the slag removal effect at one end of the rotary kiln body 2.

[0018] Specifically, such as Figures 1-2 As shown, the transmission component 4 includes two annular tracks 41 fixedly installed on the outer surface of the rotary kiln body 2. Both sides of the bottom of the two annular tracks 41 are provided with matching transmission wheels 42. The transmission wheels 42 are rotatably connected to the fixed frame 44 through the first rotating shaft 43. The fixed frame 44 is fixedly connected to the base 1. A first motor 45 is provided on one side of one of the fixed frames 44. The first motor 45 is fixedly installed on the top of the base 1 through the motor seat 46. The first rotating shaft 43 is fixedly connected to the output end of the first motor 45.

[0019] In the aforementioned components, the first motor 45 controls one of the first rotating shafts 43 to rotate, and the first rotating shaft 43 drives the transmission wheel 42 inside the support frame 3. While the transmission wheel 42 rotates, it controls the rotary kiln body 2 to rotate through the annular track 41.

[0020] Specifically, such as Figures 1-3 As shown, the slag removal mechanism 5 includes sleeves 51 fixedly installed on both sides of the support frame 3. An impact cylinder 52 is slidably installed inside the sleeves 51. A rotating cam 53 is provided inside the impact cylinder 52. A second rotating shaft 54 ​​is fixedly connected to the top center of the rotating cam 53. The top end of the second rotating shaft 54 ​​passes through the support frame 3 and extends to the outside of the support frame 3. The two second rotating shafts 54 are connected by a power component 55. Cylindrical blocks 56 are fixedly connected to both sides inside the impact cylinder 52. The cylindrical blocks 56 cooperate with the rotating cam 53. Springs 57 are provided between the impact cylinder 52 and the support frame 3. In the above components, while the transmission component 4 controls the two second rotating shafts 54 to rotate, the rotation of the second rotating shafts 54 drives the rotating cam 53. While the rotating cam 53 rotates, it pushes the impact cylinder 52 to rise inside the sleeve 51 through the cylindrical block 56 and squeezes the spring 57. When the cylindrical block 56 rises to the top of the rotating protrusion, the rotating cam 53 separates from the cylindrical block 56, the force at the bottom of the cylindrical block 56 disappears, and the spring 57 elastically recovers while pushing the impact cylinder 52 to descend rapidly, so that the impact cylinder 52 strikes the rotary kiln body 2.

[0021] Specifically, such as Figures 1-2 As shown, the power component 55 includes two first bevel gears 551 fixedly mounted on the top of the second rotating shaft 54. The two first bevel gears 551 are meshed with second bevel gears 552 on adjacent sides. The two second bevel gears 552 are respectively fixed on the outer surfaces of the output ends on both sides of the dual-axis motor 553. The dual-axis motor 553 is fixedly connected to the support frame 3. A protective box 554 is fixedly installed on the support frame 3 near the dual-axis motor 553.

[0022] In the aforementioned components, a dual-axis motor 553 is driven, and the output end of the dual-axis motor 553 drives a second bevel gear 552, which in turn drives a second rotating shaft 54 ​​to rotate inside the support frame 3.

[0023] Specifically, such as Figures 1-3 As shown, both sides of the impact cylinder 52 are fixedly connected to limit sliders 7, and the sleeve 51 is provided with a matching limit groove 8 near the limit sliders 7.

[0024] In the above components, the cooperation between the limiting slider 7 and the limiting groove 8 can limit the impact cylinder 52, so that the impact cylinder 52 can move flexibly up and down inside the sleeve 51.

[0025] Specifically, such as Figures 1-4 As shown, the feeding mechanism 6 includes a discharge box 61 rotatably installed at one end of the rotary kiln body 2. The bottom of the discharge box 61 is provided with a discharge port 62. A second motor 63 is fixedly connected to one side of the discharge box 61. A drive shaft 64 is fixedly connected to the output end of the second motor 63. An auger blade 65 is fixedly connected to the outer surface of the drive shaft 64 located inside the rotary kiln body 2.

[0026] In the aforementioned components, a second motor 63 is driven, and the output end of the second motor 63 drives a transmission shaft 64. While the transmission shaft 64 rotates, it drives the auger blades 65 to rotate inside the rotary kiln body 2. As the auger blades 65 rotate, they can not only transport materials and scrape off the residue inside the kiln, but also quickly push the residue to the outside of the device, thus improving work efficiency.

[0027] Working principle: During use, the dual-axis motor 553, the first motor 45, and the second motor 63 are driven. The first motor 45 controls one of the first rotating shafts 43 to rotate. This first rotating shaft 43 drives the transmission wheel 42 inside the support frame 3. While the transmission wheel 42 rotates, it controls the rotation of the rotary kiln body 2 through the annular track 41. The output end of the dual-axis motor 553 drives the second bevel gear 552. The second bevel gear 552 drives the second rotating shaft 54 ​​to rotate inside the support frame 3. While the second rotating shaft 54 ​​rotates, it drives the rotating cam 53. As the rotating cam 53 rotates, it pushes the impact cylinder 52 upward inside the sleeve 51 through the cylindrical block 56, and compresses the spring 57. When the cylindrical block 56 rises to the top of the rotating protrusion, the rotating cam 53 separates from the cylindrical block 56. The force at the bottom of the cylindrical block 56 disappears, and the spring 57 elastically recovers, pushing the impact cylinder 52 to descend rapidly, thus impacting the kiln. The cylinder 52 evenly taps the outer surface of the rotating rotary kiln body 2, which not only shakes off the residue adhering to the inner wall of the rotary kiln body 2, reducing the probability of residue adhering to the inner wall of the rotary kiln body 2, but also generates a certain impact force on the residue solidified inside the kiln body, causing the solidified residue to break and fall off the kiln body, thereby improving the slag removal effect. The output end of the second motor 63 drives the transmission shaft 64. While the transmission shaft 64 rotates, it drives the auger blades 65 to rotate inside the rotary kiln body 2. While the auger blades 65 rotate, they can not only transport materials and scrape off the residue inside the kiln body, but also quickly push the residue to the outside of the device, improving work efficiency. It can not only transport materials inside the rotary kiln, but also scrape off the residue adhering to the kiln body, and quickly discharge the residue that falls off the kiln body to the outside of the device, improving work efficiency.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
