Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a yellow phosphorus sludge treatment rotary kiln ring-forming prevention and scraping device. Background Art

[0002] The existing anti-ringing scraper in the yellow phosphorus sludge treatment rotary kiln is an integral setting and is placed in the yellow phosphorus sludge treatment rotary kiln. It has the following main disadvantages:

[0003] 1. Due to the high temperature in the rotary kiln for yellow phosphorus sludge treatment, the overall anti-ringing scooping stick will break after long-term use.

[0004] 2. After the overall anti-ringing sticks are broken, they gather at the rear end of the yellow phosphorus sludge treatment rotary kiln, which will cause rings to form at the front end of the yellow phosphorus sludge treatment rotary kiln. Summary of the Invention

[0005] The technical problem to be solved by the utility model is that an overlong copying roller is easy to break during operation and the breakage will cause the rotary kiln to be blocked.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a yellow phosphorus sludge treatment rotary kiln anti-ringing copying roller device, including retaining ring assemblies equidistantly distributed in the rotary kiln along the axial direction of the rotary kiln and copying rollers arranged between two adjacent retaining ring assemblies, the two ends of the copying roller respectively contact the opposite side walls of the two adjacent retaining ring assemblies, the middle and edge of the retaining ring assembly are provided with flow channels for material flow, and the edge of the retaining ring assembly is coaxially provided with an annular limiting structure for the copying roller to rotate around the center of the retaining ring assembly.

[0007] Preferably, the retaining ring assembly includes an annular ring body, which is coaxially arranged with the axis of the rotary kiln. The flow channel includes a circular notch in the center of the ring body and material passages evenly distributed on the edge of the ring body. The annular limiting structure includes a limiting ring coaxially fixed to the middle of the ring body, and the limiting ring is located outside the circular notch.

[0008] Preferably, the feed opening is fan-shaped, and the cross-sectional area of the copying roller is larger than the area of the feed opening.

[0009] Preferably, the edge of the ring body is provided with connecting ribs, and the thickness of the connecting ribs is greater than the thickness of the ring body.

[0010] Preferably, the cross-section of the copying roller is arc-shaped, and the copying roller is coaxial with the rotary kiln when located in the annular limiting structure. An arc-shaped adapting groove is provided at the end of the copying roller, and the adapting groove is adapted to the connecting rib.

[0011] Preferably, a gap is provided between the annular limiting structure and the copying roller.

[0012] The utility model provides a rotary kiln roller device for treating yellow phosphorus sludge. By equidistantly arranging retaining ring components and rollers in the rotary kiln, the rollers are arranged in sections instead of being an integral whole, and retaining ring components are arranged between each section of the rollers to prevent the rollers from axially moving in the rotary kiln. The annular limiting structure is used to ensure stable rotation of the rollers. At the same time, flow channels are provided at the center and edge of the retaining ring components to facilitate the smooth passage of the phosphorus sludge, thereby improving the stability of the rotary kiln operation and the service life of the rollers.

[0018] like Figure 1-3 As shown, the utility model proposes a yellow phosphorus sludge treatment rotary kiln anti-ringing device, comprising retaining ring assemblies 2 equidistantly distributed in the rotary kiln 1 along the axial direction of the rotary kiln 1 and a copying roller 3 arranged between two adjacent retaining ring assemblies 2, the two ends of the copying roller 3 respectively contact the opposite side walls of the two adjacent retaining ring assemblies 2, the middle and edge of the retaining ring assembly 2 are provided with flow channels for material flow, and the edge of the retaining ring assembly 2 is coaxially provided with an annular limiting structure for the copying roller 3 to rotate around the center of the retaining ring assembly 2.

[0019] The rotary kiln 1 is divided into equal parts according to its length, and a retaining ring assembly 2 is welded inside the rotary kiln 1. A copying roller 3 is processed according to the spacing between adjacent retaining ring assemblies 2 so that both ends of the copying roller 3 are in contact with adjacent retaining ring assemblies 2. During the rotation of the rotary kiln 1, the copying roller 3 rotates around the axis of the rotary kiln 1 under the restriction of the annular limiting structure, and scrapes the inner wall of the rotary kiln 1 during the rotation to clean the phosphorus mud attached to the inner wall of the rotary kiln 1. During the operation of the rotary kiln 1, the phosphorus mud inside the rotary kiln 1 flows through the flow channels in the middle and edges of the retaining ring assembly 2, so that the phosphorus mud moves along its axis inside the rotary kiln 1 and finally flows out from the discharge end of the rotary kiln 1, ensuring smooth circulation of the phosphorus mud.

[0020] like Figure 2The retaining ring assembly 2 includes an annular ring body 21, which is coaxially arranged with the axis of the rotary kiln 1. The flow channel includes a circular notch in the center of the ring body 21 and material passage openings 23 evenly distributed on the edge of the ring body 21. The annular limiting structure includes a limiting ring 22 coaxially fixed to the middle of the ring body 21, and the limiting ring 22 is located outside the circular notch.

[0021] The ring body 21 is made of an annular plate, with a feed opening 23 cut into its edge. Limiting rings 22 are welded to both end walls of the ring body 21. The diameter of the ring body 21 is equal to the inner diameter of the rotary kiln 1, and the ring body 21 is coaxially welded to the interior of the rotary kiln 1. The limiting rings 22 are welded after the copying roller 3 is placed inside the rotary kiln 1. An annular movable cavity is formed between the limiting rings 22 and the inner wall of the rotary kiln 1, allowing the copying roller 3 to rotate. After welding, the copying roller 3 moves within the annular movable cavity as the rotary kiln 1 rotates, ensuring stable rotation of the copying roller 3 around the axis of the rotary kiln 1.

[0022] As a preferred embodiment of the present invention, in order to prevent the axial movement of the copying roller 3 in the rotary kiln 1 and the blockage of the material opening 23 caused by the axial movement of the copying roller 3, the material opening 23 is fan-shaped, and the cross-sectional area of the copying roller 3 is larger than the area of the material opening 23.

[0023] like Figure 2 As shown, to improve the connection strength between the ring body 21 and the rotary kiln 1, the edge of the ring body 21 is provided with connecting ribs 24, the thickness of which is greater than that of the ring body 21. Except for the area where the material flow opening 23 is provided, the remaining positions of the edge of the ring body 21 are welded with connecting ribs 24, which are arc-shaped.

[0024] like Figure 3 As shown, the cross-section of the scoop roller 3 is arc-shaped. When located within the annular retaining structure, the scoop roller 3 is coaxial with the rotary kiln 1. An arc-shaped adapting groove 31 is formed at the end of the scoop roller 3, and the adapting groove 31 is adapted to fit the connecting rib 24. The cross-section of the scoop roller 3 is arc-shaped, and the structural ribs on the outside of the scoop roller 3 are capable of shoveling away phosphorus sludge adhering to the inner wall of the rotary kiln 1 during rotation, thereby enhancing the scoop roller 3's ability to clean phosphorus sludge.

[0025] As a preferred embodiment of the present invention, a gap is provided between the annular limiting structure and the scoop roller 3. Some phosphorus sludge is too tightly bonded to the inner wall of the rotary kiln 1. To prevent the scoop roller 3 from being stuck by the phosphorus sludge and to ensure that the scoop roller 3 does not become stuck by the phosphorus sludge during the rotation of the rotary kiln 1, the scoop roller 3 is rotated multiple times to continuously impact the phosphorus sludge on the inner wall of the rotary kiln 1, thereby scraping off the tightly adhered phosphorus sludge layer by layer.
