Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, and more specifically, to a rotary kiln anti-clogging feeding device. Background Technology

[0002] A rotary kiln is a device for heating bulk or slurry materials. Its main body is a rotating cylinder inclined at a certain angle to the horizontal. It is widely used in industries such as metallurgy, chemicals, and building materials, for example, in cement production to calcine cement clinker, in the metallurgical industry to roast ores, and in the chemical industry to produce soda ash. During operation, the material rotates and moves forward within the kiln, undergoing physical or chemical changes at high temperatures.

[0003] During material processing in a rotary kiln, material adhesion can easily lead to arching on the inner wall of the feed inlet. This arching causes uneven material accumulation at the feed inlet, resulting in blockage and hindering material discharge, significantly impacting production efficiency and product quality. Therefore, we propose an anti-blocking feed device for rotary kilns. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rotary kiln anti-clogging feeding device to solve the technical problem that the current rotary kiln feeding port is easily blocked due to material adhesion or uneven accumulation, which affects production efficiency and product quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rotary kiln anti-clogging feeding device, including an installation mechanism and a driving mechanism and a cleaning mechanism provided on the installation mechanism. The installation mechanism includes a fixed plate and an installation plate. An installation rod is arranged in an array at the front end of the installation plate. A fixing ring is welded to the end of the installation rod. The driving mechanism includes a reversing gear rotatably installed at the front end of the installation plate and a rotating ring arranged in the fixing ring. The cleaning mechanism includes a rotating shaft rotatably installed at the front end of the installation plate and a cleaning scraper arranged on the rotating shaft. A driven gear is arranged on the rotating shaft. The driven gear is meshed with the reversing gear.

[0006] Preferably, the fixing plate has an array of mounting holes, the mounting plate is bent at the end of the fixing plate, the mounting plate is inclined, and the inclination angle of the mounting plate is 3-5 degrees.

[0007] Preferably, the inner ring of the fixed ring is provided with a limiting groove, the rotating ring is located in the limiting groove, and both the outer surface of the rotating ring and the inside of the limiting groove are provided with annular grooves. The cross-section of the annular groove is hemispherical, and a ball bearing is provided in the annular groove.

[0008] Preferably, there are three reversing gears, which are arranged in an array about the rotating ring. The inner ring of the rotating ring is provided with meshing teeth, which mesh with the three reversing gears.

[0009] Preferably, the front end of the rotating ring is provided with a connecting rod, and the end of the connecting rod is provided with a pressure plate, which is L-shaped.

[0010] Preferably, there are four cleaning scrapers, and fixed rods are symmetrically installed on the cleaning scrapers. The ends of the fixed rods are connected to the rotating shaft. The cleaning scrapers are spirally arranged along the long axis. The spiral shape of the cleaning scrapers is one-third of a complete spiral. The outer end of the cleaning scrapers is designed as a pointed tip. The outer surface of the cleaning scrapers is provided with an anti-stick coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a cleaning scraper structure, allows the scraper's tip to scrape the inner wall of the rotary kiln's discharge port. The scraper's tip can scoop up materials adhering to the discharge port. The spiral design of the scraper expands its cleaning range, avoiding dead zones. Furthermore, because the scraper's spiral shape is one-third the size of a complete spiral, when the front end of the scraper is at a higher position, the beginning end is at a lower position. This height difference, combined with an anti-stick coating, allows the material scooped onto the scraper to slide off, thus allowing the material to be discharged from the rotary kiln's discharge port. This effectively prevents blockages caused by material adhesion or accumulation, ensuring smooth material discharge and solving the current problem of rotary kiln discharge ports easily becoming blocked due to uneven material adhesion or accumulation, affecting production efficiency and product quality.

[0013] 2. This utility model also features a pressure plate structure. The L-shaped pressure plate ensures stable contact between the pressure plate and the rotary kiln port. Under the action of the pressure plate, the rotary kiln can rotate on its own during operation to drive the rotating ring. The entire driving process does not require an additional power source. It cleverly utilizes the power of the rotary kiln during operation to achieve automatic cleaning, which saves energy and reduces equipment maintenance costs.

[0014] 3. This utility model also designs a rotating ring and a reversing gear structure. Under the action of the rotating ring and the reversing gear, the driven gear can rotate in the opposite direction to the rotating ring, and the cleaning scraper can rotate in the opposite direction to the rotary kiln. The reverse rotation design greatly improves the cleaning efficiency. Because of the increase in relative motion speed, the cleaning scraper can remove the material adhering to the inner wall of the rotary kiln feed port more quickly and powerfully, ensuring that the rotary kiln feed port will not be blocked.

Detailed Implementation

[0021] like Figures 1 to 5 As shown, this utility model relates to a rotary kiln anti-clogging feeding device, including an installation mechanism 100 and a drive mechanism 200 and a cleaning mechanism 300 mounted on the installation mechanism 100. The installation mechanism 100 includes a fixed plate 101 and an installation plate 102. An installation rod 103 is arrayed at the front end of the installation plate 102, and a fixing ring 104 is welded to the end of the installation rod 103. The drive mechanism 200 includes a reversing gear 205 rotatably mounted at the front end of the installation plate 102 and a rotating ring 201 disposed within the fixing ring 104. The cleaning mechanism 300 includes a rotating shaft 301 rotatably mounted at the front end of the installation plate 102 and a cleaning scraper 304 mounted on the rotating shaft 301. A driven gear 302 is mounted on the rotating shaft 301, and the driven gear 302 meshes with the reversing gear 205. This utility model features a special cleaning structure that can effectively remove material adhering to the inner wall of the rotary kiln's feed inlet and assist in material discharge, effectively preventing blockage caused by material adhesion or accumulation, and ensuring the continuous and stable operation of the rotary kiln.

[0022] Specifically, mounting holes are arrayed on the fixing plate 101, and the mounting plate 102 is bent and disposed at the end of the fixing plate 101. The mounting plate 102 is inclined at an angle of 3-5 degrees. The bending of the mounting plate 102 at an angle of 3-5 degrees allows the cleaning structure of this invention to adapt to the inclination of the rotary kiln.

[0023] Furthermore, a limiting groove is provided on the inner ring of the fixed ring 104, and the rotating ring 201 is located within the limiting groove. Both the outer surface of the rotating ring 201 and the inner surface of the limiting groove are provided with annular grooves 202. The cross-section of the annular groove 202 is hemispherical, and ball bearings 203 are disposed within the annular groove 202. The ball bearings 203 between the rotating ring 201 and the fixed ring 104 can greatly reduce the frictional force experienced by the rotating ring 201 during rotation, making the rotation process more stable and smooth.

[0024] It is worth noting that there are three reversing gears 205, which are arranged in an array about the rotating ring 201. The inner ring of the rotating ring 201 is provided with meshing teeth 204, which mesh with the three reversing gears 205. The three arrayed reversing gears 205 stably mesh with the meshing teeth 204 on the inner ring of the rotating ring 201, ensuring stable and reliable power transmission and guaranteeing the continuous and stable operation of the cleaning mechanism 300. Furthermore, the reversing gears 205 can change the rotation direction of the rotating shaft 301, so that the cleaning scraper 304 rotates in the opposite direction to the rotary kiln, ensuring the scraping efficiency of the adhering material.

[0025] It is worth mentioning that the front end of the rotating ring 201 is equipped with connecting rods 206, and the end of the connecting rods 206 is equipped with a pressure plate 207, which is L-shaped. The L-shaped design of the pressure plate 207 ensures stable contact between the pressure plate 207 and the rotary kiln port. Under the action of the pressure plate 207, the rotating ring 201 can be driven to rotate by the rotation of the rotary kiln itself during operation. The entire driving process does not require an additional power source, cleverly utilizing the power of the rotary kiln during operation to achieve automatic cleaning, which saves energy and reduces equipment maintenance costs.

[0026] It is worth noting that there are four cleaning scrapers 304. A fixing rod 303 is symmetrically installed on each cleaning scraper 304, and the end of the fixing rod 303 is connected to the rotating shaft 301. The cleaning scrapers 304 are spirally arranged along their long axis, and the spiral shape of the cleaning scrapers 304 is one-third of a complete spiral. The outer end of the cleaning scrapers 304 is a pointed design, and the outer surface of the cleaning scrapers 304 is coated with an anti-stick coating. The pointed design of the cleaning scrapers 304 can scoop up the material adhering to the rotary kiln's feed port. The spiral arrangement of the cleaning scrapers 304 allows for a wider cleaning range, avoiding cleaning dead zones. Furthermore, because the spiral shape of the cleaning scrapers 304 is one-third of a complete spiral, when the front end of the cleaning scrapers 304 is at a higher position, the starting end of the cleaning scrapers 304 is at a lower position. This height difference between the starting and ending ends of the cleaning scrapers 304, combined with the anti-stick coating, allows the material scooped up on the cleaning scrapers 304 to slide off, thus allowing the material to be discharged from the rotary kiln's feed port.

[0027] Working Principle: This embodiment provides a rotary kiln anti-clogging feeding device. In use, the entire feeding device is securely installed at the rotary kiln's discharge port using the array of mounting holes on the fixing plate 101. The mounting plate 102 is bent at a 3-5 degree angle to adapt to the rotary kiln's inclination. The cleaning scraper 304 is located inside the rotary kiln, with its tip contacting the inner wall of the rotary kiln's discharge port. The pressure plate 207 presses against the rotary kiln's discharge port (as shown in the figure). During operation, the rotary kiln rotates. Under the action of the pressure plate 207, the rotating ring 201 rotates within the fixing ring 104. The ball bearings 203 between the rotating ring 201 and the fixing ring 104 greatly reduce the friction experienced by the rotating ring 201 during rotation, making the rotation process smoother and more stable. During the rotation of the rotating ring 201, the meshing teeth 20... Under the action of 4, the reversing gear 205 can rotate, and the rotation of the reversing gear 205 can drive the driven gear 302 to rotate, which can change the direction of power transmission, so that the movement direction of the cleaning scraper 304 is opposite to the rotation direction of the rotary kiln. The movement of the cleaning scraper 304 can cause the tip of the cleaning scraper 304 to scrape the inner wall of the rotary kiln feed port. The tip of the cleaning scraper 304 can scoop up the material adhering to the feed port of the rotary kiln. Because the spiral shape of the cleaning scraper 304 is one-third of the complete spiral, when the front end of the cleaning scraper 304 is at a high position, the beginning end of the cleaning scraper 304 is at a low position. With the help of the anti-stick coating, the material scooped on the cleaning scraper 304 can slide off and be discharged from the feed port of the rotary kiln, effectively preventing the rotary kiln feed port from being blocked due to material adhesion or uneven accumulation, and ensuring that the material can be discharged smoothly from the rotary kiln.
