Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, and in particular to a detachable lifting plate device for a rotary calcining furnace. Background Technology

[0002] Rotary kiln calciners are mainly used for high-temperature heat treatment of powdery and cake-shaped materials. During operation, a large amount of solidified material adheres to or cakes onto the inner wall of the calciner. Therefore, lifting plates are often used to clean the inner wall. However, existing lifting plate devices for cleaning the inner wall of rotary kiln calciners generally cannot be adjusted according to the length of the calciner, resulting in limited applicability.

[0003] A search revealed, for example (Authorization Announcement No. CN216245479U), a detachable lifting plate device for a rotary calcining kiln, comprising a lifting plate assembly. The lifting plate assembly includes a horizontal rotating shaft with radially arranged lifting plates densely distributed along its axial direction. The lifting plate assembly is inserted into and detachably connected to the rotary calcining kiln. The rotating shaft is parallel to the rotation axis of the rotary calcining kiln, and the lifting plate assembly rotates in the same direction as the rotary calcining kiln but at a different speed. This device solves the problem of existing equipment being unable to clean the inner walls of small-diameter orifices. However, the device still has the limitation of not being adjustable according to the length of the inner wall of different calcining furnaces, reducing its applicability. Utility Model Content

[0030] An embodiment of a detachable lifting plate device for a rotary calcining furnace, such as... Figures 1 to 5 As shown,

[0031] include:

[0032] Two electrically operated telescopic columns 1 are used for installation. The structure of the electrically operated telescopic columns 1 is similar to that of an electric actuator. The height of the electrically operated telescopic columns 1 can be adjusted according to the usage conditions. A mounting plate is welded to the bottom of the electrically operated telescopic columns 1. The mounting plate is connected to the ground by screws, so that the distance between the two electrically operated telescopic columns 1 can be adjusted for easy operation.

[0033] One of the electric telescopic columns 1 has a drive motor 3 connected to its moving part by screws. The output shaft of the drive motor 3 passes through its moving part and is connected to one end of the cylinder 4. The other end of the cylinder 4 is rotatably connected to the moving part of another electric telescopic column 1. The output shaft of the drive motor 3 is controlled to rotate, which drives the connected cylinder 4 to rotate on the side walls of the two electric telescopic columns 1, thus driving the cylinder 4 and facilitating the drive of the scraper 2 connected to the cylinder 4 to complete the cleaning of the inner wall of the rotary kiln calcining furnace.

[0034] Two sets of symmetrically arranged fixing seats 5 are welded to the side wall of the cylinder 4. The fixing seats 5 are evenly arranged. The end of the fixing seat 5 is provided with a mounting hole 8. The inner wall of the mounting hole 8 is slidably connected to the insert 14. The surface of the insert 14 is provided with four symmetrical threaded holes 15. The surface of the fixing seat 5 is also provided with bolts 9 corresponding to the threaded holes 15. The bolts 9 pass through the side wall of the fixing seat 5 and connect with the threaded holes 15 to complete the connection between the fixing seat 5 and the insert 14.

[0035] A connecting hole 11 is provided at one end of the cylinder 4 for easy connection. A guiding limiting groove 10 is also provided on the outer periphery of the connecting hole 11. A threaded rod 6 is fixed to the other end of the cylinder 4. An annular limiting plate 7 is provided on the outer side of the threaded rod 6. The end of the limiting plate 7 is welded to the cylinder 4. Through the connection of the connecting hole 11 and the threaded rod 6, the two cylinders 4 are stably connected under the action of the limiting plate 7 and the limiting groove 10, which facilitates real-time adjustment according to the length of the inner wall of the calcining furnace and makes it easy to use.

[0036] A fixing post 13 is welded to one side of the insert block 14. A movable post 12 is slidably connected to the other end of the fixing post 13. A toothed plate 16 is provided on the side wall of the fixing post 13. The toothed plate 16 is connected to the fixing post 13 through a fixing member. A handle is provided on the top of the toothed plate 16. The handle makes it easy to remove the toothed plate 16. A fixing tooth is also provided at the bottom of the toothed plate 16 for fixing.

[0037] A toothed belt 17 is provided on the side wall of the movable column 12. The toothed belt 17 has a toothed groove inside, which meshes with the fixed tooth, thereby completing the fixation of the toothed belt 17 and the toothed plate 16. The movable column 12 and the fixed column 13 can be adjusted by the fixing parts and the handle, which facilitates operation.

[0038] An insertion hole 19 is provided at the end of the movable column 12. A connecting block 18 is slidably connected to the inner wall of the insertion hole 19. The connecting block 18 is connected to the insertion hole 19 in the movable column 12 by screws. A scraper 2 is welded to the end of the connecting block 18. The end of the scraper 2 abuts against the movable column 12, thereby driving the scraper 2 by the fixed seat 5. Under the action of the drive motor 3, the cleaning of the inner wall of the calcining furnace is completed.

[0039] The electric telescopic column 1 and the drive motor 3 are both conventional instruments. Their working principles, dimensions and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0040] Working principle

[0041] The detachable lifting plate device for rotary kiln calcining furnace, when used, corresponds the connecting holes 11 and threaded rods 6 at both ends of the cylinder 4 according to the length of the inner wall of the rotary kiln calcining furnace, and completes the connection of the two cylinders 4 under the action of the limiting plate 7 and the limiting groove 10.

[0042] At this time, one of the electric telescopic columns 1 is installed on one side of the calcining furnace and connected to the ground through a fixing plate. The cylinder 4 penetrates the inner wall of the calcining furnace and is connected to the electric telescopic column 1. The other end of the cylinder 4 is connected to the electric telescopic column 1 on the other side of the calcining furnace, and one end of the cylinder 4 is connected to the output shaft of the installed drive motor 3.

[0043] When the cylinder 4 enters the calcining furnace, the positions of each fixed column 13 and moving column 12 are adjusted according to the position of the cylinder 4. Under the action of the toothed plate 16 and toothed belt 17, the extension length of the moving column 12 is adjusted, and the scraper 2 is connected to the moving column 12.

[0044] Finally, the output shaft of the drive motor 3 is rotated, which drives the connected cylinder 4 to rotate. Under the action of the scraper 2, the cleaning of the inner wall of the rotary kiln calcining furnace is completed.
