Description

Technical Field

[0001] This application relates to the technical field of rotary kiln accessories, specifically a rotary kiln thrust roller for cement production. Background Technology

[0002] The cement production process begins with raw material mining and transportation: limestone is obtained from blasting in the mine, and combined with auxiliary raw materials such as clay, iron ore powder, and coal, and transported to the plant area via long belt conveyors. After that, the raw materials undergo crushing and pre-homogenization, raw meal preparation, preheating and external decomposition in the kiln, clinker calcination in the rotary kiln, clinker cooling and cement grinding, and finished product packaging and delivery. The most important part is the clinker calcination in the rotary kiln: the preheated material is fed into the rotary kiln and undergoes a series of solid-phase reactions in a high-temperature environment of about 1400℃, and finally sintersted into cement clinker particles. A rotary kiln is composed of a series of components, including the kiln shell, kiln lining, tire, support rollers and bearing assembly, and thrust roller device. The thrust roller device is divided into mechanical thrust rollers and hydraulic thrust rollers, which precisely limit the vertical axial movement of the kiln shell, ensure uniform wear of all support rollers and tires, and prevent kiln body displacement from causing equipment failure. However, the rotary kiln thrust rollers used in cement production are exposed to the outside for a long time. Occasionally, some hard debris will adhere to the surface of the rotary kiln tire. When these debris enters between the thrust roller and the tire, the thrust roller will hinder the rotation of the rotary kiln when it is rotating, which will aggravate the wear of the thrust roller and the tire.

[0003] Therefore, it is necessary to provide a rotary kiln thrust roller for cement production to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a rotary kiln impeller for cement production, which can open outwards and ensure that when encountering hard debris, the debris falls off the tire after the rotary kiln rotates normally, thus maintaining the stable operation of the device.

[0006] The technical solution adopted by this application to solve its technical problem is: a rotary kiln thrust roller for cement production, including a base, a second rotating plate rotatably connected to the middle position of the top of the base, a first rotating plate rotatably connected to the middle position of the top of the second rotating plate, mounting seats fixed at both ends of the top of the base, a hydraulic rod rotatably connected to one end of the mounting seat, a hydraulic spring installed on the outside of the hydraulic rod, a sliding cavity opened on one side of the first rotating plate and the second rotating plate, a sliding rod fixed inside the sliding cavity, a sliding seat slidably connected to the outside of the sliding rod, and thrust rollers rotatably installed at both ends of the top of the first rotating plate and the second rotating plate.

[0007] Furthermore, mounting bases are installed on both sides of the top of the base, and each of the two sets of mounting bases has a rotatable support roller inside.

[0008] Furthermore, the bottom center of the first rotating plate and the top center of the second rotating plate are both provided with mutually cooperating rotating grooves.

[0009] Furthermore, a rotating shaft is rotatably mounted between the first rotating plate and the second rotating plate, and the rotating shaft is rotatably connected to the base.

[0010] Furthermore, the sliding seat is rotatably connected to the output end of the hydraulic rod, the end of the hydraulic spring is connected to the end of the hydraulic rod, and the head end of the hydraulic spring is connected to the output end of the hydraulic rod.

[0011] Furthermore, the top two ends of the mounting base are externally mounted with support plates having an arc-shaped cross-section, and the outer side of the support roller is provided with an anti-rust coating.

[0012] The beneficial effects of this application are: 1. This application provides a rotary kiln thrust roller for cement production. Thrust rollers are rotatably installed at both ends of the top of a first rotating plate and a second rotating plate, ensuring a rotatable connection between the two plates. Hydraulic rods, in conjunction with hydraulic springs, are rotatably installed on both sides of the base top to compress the first and second rotating plates, causing them to move away from each other. This, combined with the thrust rollers, limits the rotation of the rotary kiln. When hard impurities exist between the outer tire of the rotary kiln and the thrust rollers, the compressive force pushes the thrust rollers, causing the first and second rotating plates to move closer together, facilitating normal rotation of the rotary kiln. When softer impurities pass between the thrust rollers and the surface tire of the rotary kiln, the compressive force from the thrust rollers breaks or deforms the impurities, preventing them from adhering to the surface tire of the rotary kiln, thus ensuring normal rotation of the rotary kiln. Simultaneously, it reduces wear on the support rollers and tire, ensuring stable long-term operation of the equipment.

[0013] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1-6As shown, this application provides a rotary kiln thrust roller for cement production, including a base 1, a second rotating plate 5 rotatably connected to the middle position of the top of the base 1, a first rotating plate 4 rotatably connected to the middle position of the top of the second rotating plate 5, mounting seats 9 fixed at both ends of the top of the base 1, a hydraulic rod 10 rotatably connected to one end of the mounting seat 9, a hydraulic spring 11 installed on the outside of the hydraulic rod 10, a sliding cavity 12 opened on one side of the first rotating plate 4 and the second rotating plate 5, a sliding rod 13 fixed inside the sliding cavity 12, a sliding seat 14 slidably connected to the outside of the sliding rod 13, and thrust rollers 8 rotatably installed at both ends of the top of the first rotating plate 4 and the second rotating plate 5.

[0019] In this embodiment, thrust rollers 8 are rotatably installed at both ends of the top of the first rotating plate 4 and the second rotating plate 5, so that the first rotating plate 4 and the second rotating plate 5 are rotatably connected. Hydraulic rods 10 are rotatably installed on both sides of the top of the base 1, and hydraulic springs 11 are used to squeeze the first rotating plate 4 and the second rotating plate 5 away from each other. The thrust rollers 8 limit the rotation of the rotary kiln. When there are hard impurities between the outer tire of the rotary kiln and the thrust rollers 8, the squeezing force will push the thrust rollers 8, thereby driving the first rotating plate 4 and the second rotating plate 5 closer together, which facilitates the normal rotation of the rotary kiln. When soft impurities pass between the thrust rollers 8 and the outer tire of the rotary kiln, the impurities are broken or deformed, preventing the impurities from adhering to the outer tire of the rotary kiln, thus ensuring the normal rotation of the rotary kiln. At the same time, it can reduce the damage to the support rollers 3 and the tires, and ensure the stable operation of the equipment for a long time.

[0020] like Figure 1 and 4 As shown, mounting bases 2 are installed on both sides of the top of the base 1. Rollers 3 are rotatably installed inside both sets of mounting bases 2. A rotating shaft 7 is rotatably installed between the first rotating plate 4 and the second rotating plate 5. The rotating shaft 7 is rotatably connected to the base 1. A support plate 15 with an arc cross-section is installed on both ends of the top of the mounting base 2. The outer side of the rollers 3 is provided with an anti-rust coating.

[0021] In this embodiment, the mounting base 2, together with the support rollers 3, supports the rotary kiln, ensuring its normal rotation. The bottom of the base 1 is an inclined mechanism to maintain the kiln's tilt. The rotating shaft 7 ensures stable rotation between the first rotating plate 4 and the second rotating plate 5, preventing deviation. External installation can be achieved by welding or screw installation, with the support plate 15 installed at both ends of the mounting base 2. Its overall height is lower than the height of the support rollers 3. In case of damage or fall of the support rollers 3, the support plate 15 can provide emergency support for the rotary kiln. The anti-rust coating prevents the support rollers 3 from rusting and causing severe wear.

[0022] like Figure 3As shown, rotating grooves 6 that cooperate with each other are provided at the middle position of the bottom of the first rotating plate 4 and the middle position of the top of the second rotating plate 5.

[0023] In this embodiment, the rotating groove 6 ensures that the tops of the first rotating plate 4 and the second rotating plate 5 are on the same horizontal plane, thereby ensuring that the four sets of thrust rollers 8 can stably clamp the rotary kiln.

[0024] like Figure 3 As shown, the sliding seat 14 is rotatably connected to the output end of the hydraulic rod 10, the end of the hydraulic spring 11 is connected to the end of the hydraulic rod 10, and the head end of the hydraulic spring 11 is connected to the output end of the hydraulic rod 10.

[0025] In this embodiment, the sliding seat 14 is rotatably connected to the output end of the hydraulic rod 10, and the sliding seat 14 is limited in movement by the sliding cooperation between the sliding rod 13 and the sliding seat 14. Due to the yielding of the thrust roller 8, the tilt angle of the hydraulic rod 10 needs to be changed under the action of the triangle principle. With the cooperation of the sliding seat 14 and the sliding rod 13, the hydraulic rod 10 can be shortened and lengthened normally while the angle is changed. The first end of the hydraulic spring 11 is connected to the output end of the hydraulic rod 10, and the last end is connected to the last end of the hydraulic rod 10. The hydraulic rod 10 is initially in an extended state, and the hydraulic spring 11 is in a relaxed state. When there are impurities between the thrust roller 8 and the tire, the hydraulic rod 10 can be shortened due to the squeezing force. At this time, the hydraulic spring 11 is compressed. The compressed hydraulic spring 11 can play a counter-pushing force, so that the tire and the thrust roller 8 are stably fitted, thereby ensuring the stable limitation of the rotary kiln by the thrust roller 8.

[0026] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
