Description

Technical field:

[0001] The utility model relates to the technical field of sodium metal production equipment, in particular to a track-type rotary vibration mechanical automatic scraper driving device. Background technology:

[0002] In the production process of metallic sodium, sodium chloride is electrolyzed in an electrolytic cell to produce metallic sodium. The sodium liquid produced during the electrolysis process will be fed into the electrolytic cell receiver. During the rising process of the liquid sodium, it will gather in the riser, and metallic calcium will adhere to the pipe wall, affecting the entry of metallic sodium into the receiver.

[0003] At present, the accumulation on the inner wall of the receiver riser is removed by manually operating a scraper, but the manual removal operation is labor-intensive. In order to reduce the labor intensity, the prior art usually adopts pneumatically driven scraper lifting and pulling, such as the Chinese patent "Scraper Shaft Driving Device" with patent number 202222667378.X, which includes a drive motor and a scraper lifting drive. The scraper lifting drive is a cylinder, which controls the scraper spline shaft to move up and down in the scraper drive sleeve through the extension and retraction of the cylinder to achieve the lifting effect on the scraper.

[0004] However, the above patented technology has the following problems in actual application: (1) The air source supplying air to the cylinder has unstable pressure, and there are many components on the air path, which is prone to air leakage, resulting in a decrease in the activity of the scraper, poor reliability, and failure to meet production needs; (2) After the cylinder is frequently operated for a certain period of time, air leakage will occur, resulting in poor cleaning effect and failure to meet process requirements; (3) Since there are many accessories driven by the cylinder and the failure rate is high, long-term stable production cannot be achieved, and frequent replacement of cylinders increases production costs. Utility model content:

[0007] Furthermore, the cover shell is a cylindrical structure.

[0008] Furthermore, a plurality of guide keys are evenly distributed along the circumferential direction on the side wall of the rotating shaft.

[0009] Furthermore, the transmission assembly is a gear meshing transmission or a sprocket chain transmission.

[0010] Furthermore, the guide track is a spiral structure, and the rotating arm moves along the top surface of the guide track.

[0011] Furthermore, the guide track includes two tracks placed on both sides of the rotating shaft, the lowest end of each guide track is placed below the highest end of another guide track, and two rotating arms that move along the corresponding guide tracks are fixed on the rotating shaft.

[0012] Furthermore, each section of the guide rail is a three-section structure, which is divided into a movable rail in the middle section, and two fixed rails in the low section and the high section. One end of the movable rail is hinged to the fixed rail in the low section, and the other end of the movable rail is overlapped on the fixed rail in the high section through an inclined surface.

[0013] Furthermore, a reverse low-position track and a reverse high-position track are symmetrically fixed on the inner wall of the cover shell and the two sections of the fixed track of the low section and the high section of each section of the guide track; the hinge axis of the movable track on the same side of the reverse low-position track is simultaneously passed through the reverse low-position track, and the other end of the movable track is movably overlapped on the reverse high-position track on the same side through an inclined surface.

[0015] The advantages of the utility model are as follows: during the rotation of the shaft, the rotating arm moves from the lowest position to the highest position along the guide track, and at the same time drives the shaft to lift upward under the action of the spline guide. After passing the highest position, the rotating arm falls to the lowest position of the guide track. At this time, the shaft also falls downward, which effectively vibrates the aggregates on the inner wall of the receiver and on the scraper, and is more conducive to removing the aggregates. In this way, while the shaft rotates, it rises and falls back and forth according to the above process, so as to achieve the purpose of effectively removing the aggregates on the inner wall of the receiver.

[0027] Example 1: Figures 1 to 3 As shown, this embodiment provides an orbital rotary vibration mechanical automatic scraper drive device, which includes a drive motor 1, a transition shaft 2, a scraper shaft 8, a sleeve 4, a cover shell 3, a rotating shaft 5, a guide track 9 and a rotating arm 10; the cover shell 3 is a cylindrical structure, and a shield 18 is connected to the cover shell 3. The drive motor 1 is fixed on the top surface of the shield 18. The output shaft of the drive motor 1 is arranged downward, and after passing through the shield 18, it is coaxially connected to the top end of the transition shaft 2 through a coupling. The bottom end of the transition shaft 2 is rotatably connected to the bottom surface of the shield 18, and the transition shaft 2 is driven to rotate by the drive motor 1.

[0028] A shaft sleeve 4 is installed on the bottom surface of the cover shell 3 and is parallel to and rotatably arranged relative to the transition shaft 2. A rotating shaft 5 is coaxially penetrated on the shaft sleeve 4. The rotating shaft 5 is provided with a plurality of guide keys 6, i.e., splines, which cooperate with the key grooves on the inner wall of the shaft sleeve 4. The transition shaft 2 is connected to the shaft sleeve 4 through a transmission assembly 7. In this embodiment, the transmission assembly 7 is a sprocket chain transmission, i.e., a driving sprocket is fixedly mounted on the transition shaft 2, and a driven sprocket is fixedly mounted on the shaft sleeve 4. The driving sprocket is connected to the driven sprocket through a chain. The bottom end of the rotating shaft 5 is connected to the top end of the scraper shaft 8 through a coupling, and the top end of the rotating shaft 5 passes through the top surface of the cover shell 3.

[0029] In this embodiment, the bottom surface of the protective cover 18 is fixed to the top of the receiver 20 through the connecting column 19, and the part of the scraper shaft 8 fixed with the scraper at the bottom is placed in the receiver 20; when the driving motor 1 drives the transition shaft 2 to rotate, the transmission assembly 7 drives the sleeve 4 to rotate, and the sleeve 4 drives the rotating shaft 5 to rotate under the action of the spline, and the rotating shaft 5 drives the scraper shaft 8 to rotate through the coupling. During the rotation of the scraper shaft 8, the scraper fixed on it is driven to remove the aggregates on the inner wall of the receiver 20.

[0030] The inner wall of the cover 3 is connected with a guide track 9 arranged along the circumference of the rotating shaft 5. The guide track 9 is arranged obliquely along the axial direction of the rotating shaft 5. In this embodiment, the guide track 9 is a spiral structure. A rotating arm 10 that moves along the top surface of the guide track 9 is fixed to the rotating shaft 5. During the rotation of the rotating shaft 5, the rotating arm 10 moves from the lowest position to the highest position along the guide track 9, and at the same time drives the rotating shaft 5 to rise upward under the action of the spline guide. During the lifting process from the lowest position to the highest position, the rotating shaft 5 rotates 360° and then falls. After passing the highest position, the rotating arm 10 falls to the lowest position of the guide track 9. At this time, the rotating shaft 5 also falls downward, which is conducive to the receiving The accumulation on the inner wall of the receiver 20 and on the scraper is effectively vibrated, which is more conducive to removing the accumulation. In this way, while the shaft 5 rotates, it rises and falls back and forth according to the above process, so as to achieve the purpose of effectively removing the accumulation on the inner wall of the receiver 20. In addition, the present embodiment has a simple structure and is driven by only one drive motor 1 to complete the rotation of the shaft 5 and the lifting and lowering at the same time. A large impact is formed during the landing process to achieve a vibration effect. Compared with the prior art, it not only reduces the labor intensity of manual work, but also does not require the use of air source and corresponding accessories, eliminates the problem of air leakage and the failure rate of pneumatic accessories, and achieves long-term stable operation.

[0031] Example 2: Figure 4 As shown, this embodiment provides a track-type rotary vibration mechanical automatic scraper drive device, which is different from Example 1 in that the guide track 9 includes two sections of tracks separately placed on both sides of the rotating shaft 5, and the lowest end of each guide track 9 is placed below the highest end of the other guide track 9. Specifically, the highest ends of the two guide tracks 9 are symmetrical and at the same height relative to the rotating shaft 5, and the lowest ends of the two guide tracks 9 are also symmetrical relative to the rotating shaft 5 and fit with the bottom surface of the cover 3. Two rotating arms 10 that move along the corresponding guide tracks 9 are symmetrically fixed on the rotating shaft 5; other structures are the same as Example 1.

[0032] Compared with Example 1, two rotating arms 10 are provided in this embodiment to move along the corresponding guide rails 9, which is beneficial to increase the force strength and balance. During the lifting process of the rotating shaft 5 from the lowest position to the highest position, it rotates 180° and then falls, which accelerates the lifting frequency and is more conducive to clearing aggregates.

[0033] Example 3: Figures 5 to 7As shown, this embodiment provides a track-type rotary vibration mechanical automatic scraper driving device, which is different from Example 2 in that each section of the guide track 9 is a three-section structure, which is divided into a movable track 11 in the middle section, and two fixed tracks 12 in the low section and the high section. One end of the movable track 11 is hinged to the end of the fixed track 12 in the low section, and the other end of the movable track 11 is overlapped on the fixed track 12 in the high section through an inclined surface 13, that is, the other end of the movable track 11 and the corresponding end of the fixed track 12 in the high section are provided with inclined surfaces 13 in the same direction, and the inclined surface 13 at the other end of the movable track 11 is movably overlapped on the inclined surface 13 of the fixed track 12 in the high section, that is, after the movable track 11 is swung around the hinge shaft 16 and overlapped on the fixed track 12 in the high section, the fixed track 12 in the low section, the movable track 11 and the fixed track 12 in the high section form a complete track.

[0034] On the inner wall of the cover shell 3, two fixed rails 12 of the low section and the high section of each guide rail 9 are symmetrically fixed with a reverse low rail 14 and a reverse high rail 15 relative to the rotating shaft 5; the hinge shaft 16 of the movable rail 11 on the same side of the reverse low rail 14 is simultaneously penetrated on the reverse low rail 14, and the other end of the movable rail 11 is movably overlapped on the reverse high rail 15 on the same side through the inclined surface 13; when the movable rail 11 is forced to swing in the reverse direction around the hinge shaft 16 and overlapped on the reverse high rail 15, the reverse low rail 14, the movable rail 11 and the reverse high rail 15 form a complete track.

[0035] A high-level drop opening is left between the highest end of the fixed rail 12 of the high-level section and the highest end of the symmetrical reverse high-level rail 15, and the lowest end of the fixed rail 12 of the low-level section abuts against the lowest end of the symmetrical reverse low-level rail 14, and a "V"-shaped slope 17 is provided at the abutment, and the slope 17 is placed directly below the high-level drop opening between the fixed rail 12 and the reverse high-level rail 15.

[0036] After the two sections of movable rails 11 are swung around the corresponding hinge shafts 16 and overlapped on the fixed rails 12 of the corresponding high-position section, during the forward rotation of the shaft 5, the two rotating arms 10 on the shaft 5 move upward from the low position to the high position along the corresponding guide rails 9, and then fall from the high-position drop mouth to the low-position slope 17, and so on, so as to realize the lifting and lowering of the shaft 5 while rotating in the forward direction; in order to further improve the cleaning efficiency, in this embodiment, after the shaft 5 rotates forward for a period of time, the drive motor 1 is controlled to reverse to drive the shaft 5 to rotate in the reverse direction, thereby driving the two rotating arms 10 from the slope 17 along the reverse direction The low-level track 14 climbs, and when it climbs to the movable track 11, the rotating arm 10 drives the movable track 11 to swing in the opposite direction around the hinge shaft 16 and overlaps the reverse high-level track 15. In this way, the rotating arm 10 continues to climb along the movable track 11 and the reverse high-level track 15 until it falls from the high-level drop mouth to the low-level slope 17, and this reciprocating process is performed to achieve the lifting and lowering of the rotating shaft 5 while rotating in the reverse direction; therefore, this embodiment can achieve the alternating operation of the rotating shaft 5 while lifting and lowering in the forward rotation and while lifting and lowering in the reverse rotation, so as to achieve the purpose of efficiently removing the aggregates on the inner wall of the receiver 20.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
