Description

Technical Field

[0001] This utility model relates to the field of sodium production technology through electrolytic metal production, specifically, to a mechanical automatic scraper that replaces manual labor in sodium production through electrolytic metal production. Background Technology

[0002] During the electrolysis process in the electrolytic cell, a large amount of sticky substances on the cell wall and in the sodium metal collection device need to be cleaned in time, otherwise they will stick to the wall and block the pipes. Among them, the scraper is an important auxiliary tool used to scrape off the impurities and deposits accumulated in the electrolytic cell in order to maintain the stability and efficiency of the electrolysis process.

[0003] A search revealed a Chinese patent publication, CN201857429U, which discloses an "automatic lifting and rotating device for a scraper, comprising a horizontally arranged housing, in which a meshing gear and a rack are installed; a first driving device installed at one end of the housing for driving the rack; a second driving device installed above the housing, the second driving device being rotatably connected to a connecting rod, the connecting rod passing through the mounting hole of the gear and extending out of the housing, and connected to a scraper; the gear and the connecting rod being slidably fitted together, and the gear rotating causing the connecting rod to rotate synchronously; and a control device for controlling the alternating operation of the first driving device and the second driving device."

[0004] However, in the process of implementing the relevant technologies, this type of patent has certain technical defects:

[0005] This patent controls the piston rod of the first cylinder to extend and retract left and right at certain time intervals, causing the scraper to move up and down to clean the inner wall of the electrolytic cell. However, in this cleaning method, the scraper is always in contact with the inside of the electrolytic cell during cleaning. After the attachments are removed, these attachments will accumulate on the scraper, which will affect the scraper's subsequent cleaning ability.

[0006] The main function of this patent is to perform unidirectional cleaning in the vertical direction. The cleaning method is limited, and it is not possible to completely remove some impurities with strong adsorption by applying scraping force in one direction, resulting in poor cleaning effect. In view of this, this utility model proposes a mechanical automatic scraper to replace manual cleaning when producing sodium by electrolysis of metal. Utility Model Content

The top end of the main shaft is provided with a lifting component that drives the main shaft to move up and down reciprocally by cooperating with the rotation of the main shaft. The top end of the first rotating shaft is provided with a transmission component that drives the first rotating shaft to rotate by cooperating with the rotation of the rotating base.

[0009] Preferably, the telescopic shaft includes a sleeve shaft, the bottom end of which is fixedly connected to the main shaft, and the top end of which is slidably connected to an insert shaft. The top end of the insert shaft is fixedly connected to the output shaft of the motor, and a limit strip is fixedly connected to the outer side of the insert shaft. The limit strip is slidably connected to the inner wall of the sleeve shaft.

[0010] Preferably, the inner wall of the sleeve is provided with a limiting groove that matches the limiting strip, and the limiting strip can slide vertically along the limiting groove.

[0011] Preferably, the lifting component includes a rotating plate, which is fixedly connected to the top end of the main shaft. An arc-shaped top block is fixedly connected to one end of the bottom of the rotating plate, and an arc-shaped protrusion is fixedly connected to one end of the top of the mounting bracket. The arc-shaped top block intermittently contacts the arc-shaped protrusion in conjunction with the rotation of the main shaft. A return spring is sleeved on the main shaft, with the top end of the return spring contacting the bottom wall of the frame and the bottom end of the return spring contacting the rotating plate.

[0012] Preferably, the transmission component includes a fixed sleeve sleeved on the outside of the main shaft, the fixed sleeve being fixedly connected to the bottom of the mounting bracket, a spline being fixedly connected to the bottom end of the fixed sleeve, a transmission shaft being rotatably connected to the middle of the rotating seat, a first gear being fixedly connected to the top of the transmission shaft, the first gear meshing with the spline and being able to slide along the axis of the spline, and a second gear being fixedly connected to the top end of the first rotating shaft, the second gear meshing with the first gear.

[0013] Preferably, the flipping component includes an incomplete gear, which is coaxially and fixedly connected to a first gear. A third rotating shaft is rotatably connected to the inner side of the first rotating shaft, penetrating the top wall of the first rotating shaft. The third rotating shaft is concentrically arranged with the first rotating shaft. A third gear is fixedly connected to the top of the third rotating shaft. The incomplete gear and the third gear mesh intermittently. A plurality of first bevel gears are fixedly connected to the bottom of the third rotating shaft.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. By starting the motor, the telescopic shaft is driven to rotate, which in turn causes the main shaft to rotate. This causes the rotating seat to rotate synchronously, and the first rotating shaft to move circumferentially around the main shaft. This allows all the scraper blades to slide along the inner wall of the electrolytic cell, thus cleaning the deposits on the inner wall of the electrolytic cell. At the same time, the lifting component can drive the main shaft to move up and down, which in turn causes all the scraper blades to move up and down. This allows for the cleaning of deposits at different heights on the inner wall of the electrolytic cell, greatly improving the cleaning effect.

[0019] 2. The transmission component can work with the rotation of the rotating seat to make the first rotating shaft rotate, which in turn makes all the scraper pieces move circumferentially on the horizontal plane, causing the scraper pieces to disengage from the inner wall of the electrolytic cell intermittently. This allows the scraper pieces to throw out the accumulated impurities when they disengage from the inner wall of the electrolytic cell, thus avoiding the problem of impurities accumulating on the scraper pieces and reducing their cleaning ability.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-8As shown, this embodiment proposes a mechanical automatic scraper to replace manual labor in the electrolytic production of sodium from metals. It includes a frame 1, with a mounting frame 4 fixedly connected to the bottom of the frame 1. A scraper structure 2 for cleaning the inner wall of the electrolytic cell 3 is provided at the bottom of the mounting frame 4. The scraper structure 2 includes a main shaft 22 penetrating the mounting frame 4, which is movably connected to the mounting frame 4. A telescopic shaft 23 is fixedly connected to the top of the main shaft 22. A motor 21 is fixedly mounted on the top of the frame 1, and the output shaft of the motor 21 is fixedly connected to the top end of the telescopic shaft 23. A rotating seat 24 is fixedly connected to the bottom of the main shaft 22, and a through-hole is rotatably connected to one end of the rotating seat 24. The first rotating shaft 25 is rotatably connected to a number of second rotating shafts 26 on its outer side. The number of second rotating shafts 26 are equidistantly distributed along the vertical direction. One end of each of the number of second rotating shafts 26 is provided with a scraper 27 that abuts against the inner wall of the electrolytic cell 3. The top end of the main shaft 22 is provided with a lifting member 28 that drives the main shaft 22 to move up and down reciprocally by cooperating with the rotation of the main shaft 22. The top end of the first rotating shaft 25 is provided with a transmission assembly 29 that drives the first rotating shaft 25 to rotate by cooperating with the rotation of the rotating seat 24. The inner side of the first rotating shaft 25 is provided with a flipping member 20 that drives all the second rotating shafts 26 to flip intermittently by cooperating with the rotation of the rotating seat 24.

[0032] By starting the motor 21, the telescopic shaft 23 is driven to rotate, which causes the main shaft 22 to rotate. This causes the rotating seat 24 to rotate synchronously, and the first rotating shaft 25 to move circumferentially around the main shaft 22. This allows all the scraper pieces 27 to slide along the inner wall of the electrolytic cell 3, thereby cleaning the deposits on the inner wall of the electrolytic cell 3. At the same time, the lifting member 28 can drive the main shaft 22 to move up and down, which also causes all the scraper pieces 27 to move up and down. This allows the deposits at different heights on the inner wall of the electrolytic cell 3 to be cleaned, greatly improving the cleaning effect.

[0033] The transmission assembly 29 can cooperate with the rotation of the rotating seat 24 to make the first rotating shaft 25 rotate, which in turn makes all the scraper pieces 27 move circumferentially on the horizontal plane, causing the scraper pieces 27 to disengage from the inner wall of the electrolytic cell 3 intermittently. This allows the scraper pieces 27 to throw out the accumulated impurities when they disengage from the inner wall of the electrolytic cell 3, thus avoiding the problem of reduced cleaning ability of the scraper pieces 27 due to the accumulation of impurities on the scraper pieces 27.

[0034] Furthermore, the telescopic shaft 23 includes a sleeve shaft 231, the bottom end of which is fixedly connected to the main shaft 22. A plug shaft 232 is slidably connected to the top end of the sleeve shaft 231, and the top end of the plug shaft 232 is fixedly connected to the output shaft of the motor 21. A limit strip 233 is fixedly connected to the outer side of the plug shaft 232, and the limit strip 233 is slidably connected to the inner wall of the sleeve shaft 231. A limit groove 234 matching the limit strip 233 is provided on the inner wall of the sleeve shaft 231, allowing the limit strip 233 to slide vertically along the limit groove 234. When the main shaft 22 reciprocates up and down, the sleeve shaft 231 and the plug shaft 232 slide relative to each other. The limit strip 233 restricts the relative rotation between the sleeve shaft 231 and the plug shaft 232, thereby ensuring stable power transmission between them.

[0035] Furthermore, the lifting component 28 includes a rotating plate 281, which is fixedly connected to the top of the main shaft 22. An arc-shaped top block 282 is fixedly connected to one end of the bottom of the rotating plate 281. An arc-shaped protrusion 283 is fixedly connected to one end of the top of the mounting bracket 4. The arc-shaped top block 282 intermittently contacts the arc-shaped protrusion 283 in coordination with the rotation of the main shaft 22. A return spring 284 is sleeved on the main shaft 22. The top of the return spring 284 contacts the bottom wall of the frame 1, and the bottom of the return spring 284 contacts the rotating plate 281. By starting the motor 21, the telescopic shaft 23 is driven to rotate, causing the main shaft 22 to rotate. This causes the rotating plate 281 to drive the arc-shaped top block 282 to rotate. When the arc-shaped top block 282 contacts the arc-shaped protrusion 283, the arc-shaped top block 282 is squeezed and moves upward, causing the main shaft 22 to move upward. This compresses the return spring 284 and accumulates potential energy. When the arc-shaped top block 282 disengages from the arc-shaped protrusion 283, the return spring 284 releases potential energy, causing the arc-shaped top block 282 to move downward, which in turn causes the main shaft 22 to move downward. This cycle repeats, allowing the main shaft 2 to move up and down repeatedly, causing all the scraper pieces 27 to move up and down repeatedly. This allows for the cleaning of deposits at different heights on the inner wall of the electrolytic cell 3, greatly improving the cleaning effect.

[0036] Furthermore, the transmission component 29 includes a fixed sleeve 291 sleeved on the outside of the main shaft 22. The fixed sleeve 291 is fixedly connected to the bottom of the mounting bracket 4. A spline 292 is fixedly connected to the bottom end of the fixed sleeve 291. A transmission shaft 293 is rotatably connected to the middle of the rotating seat 24. A first gear 294 is fixedly connected to the top of the transmission shaft 293. The first gear 294 meshes with the spline 292 and can slide along the axial direction of the spline 292. A second gear 295 is fixedly connected to the top end of the first rotating shaft 25. The second gear 295 meshes with the first gear 294. The inner diameter of the fixed sleeve 291 is larger than the diameter of the main shaft 22. The inner diameter of the spline 292 is the same as the inner diameter of the fixed sleeve 291.

[0037] When the rotating seat 24 rotates, the transmission shaft 293 will rotate circumferentially along with the rotating seat 24, which causes the first gear 294 to roll around the spline 292, causing the transmission shaft 293 to rotate, which in turn causes the first gear 294 to drive the second gear 295 to rotate, thereby causing the first rotating shaft 25 to rotate synchronously. This causes all the scraper pieces 27 to move circumferentially on the horizontal plane, causing the scraper pieces 27 to intermittently detach from the inner wall of the electrolytic cell 3. This allows the scraper pieces 27 to throw out the accumulated impurities when they detach from the inner wall of the electrolytic cell 3, thus avoiding the problem of impurities accumulating on the scraper pieces 27 and reducing the cleaning ability of the scraper pieces 27.

[0038] Furthermore, the flipping component 20 includes an incomplete gear 201, which is coaxially and fixedly connected to the first gear 294. A third rotating shaft 202, which passes through the top wall of the first rotating shaft 25, is rotatably connected to the inner side of the first rotating shaft 25. The third rotating shaft 202 is concentrically arranged with the first rotating shaft 25. A third gear 203 is fixedly connected to the top of the third rotating shaft 202. The incomplete gear 201 and the third gear 203 mesh intermittently. The number of teeth of the incomplete gear 201 is one-quarter of the number of teeth of the third gear 203. A plurality of first bevel gears 204 are fixedly connected to the bottom of the third rotating shaft 202. The plurality of first bevel gears 204 are equidistantly distributed along the vertical direction. A second bevel gear 205 is fixedly connected to one end of a plurality of second rotating shafts 26. The plurality of second bevel gears 205 mesh with the corresponding first bevel gears 204.

[0039] When the rotating seat 24 rotates, the transmission shaft 293 rotates circumferentially along with the rotating seat 24, causing the first gear 294 to roll around the spline 292, causing the transmission shaft 293 to rotate, which in turn causes the incomplete gear 201 to rotate. When the incomplete gear 201 meshes with the third gear 203, the third gear 203 rotates, causing the third shaft 202 to rotate. When the incomplete gear 201 disengages from the third gear 203, the third shaft 202 stops rotating. This cycle repeats, causing the third shaft 202 to rotate intermittently. Due to the number of teeth on the incomplete gear 201... Since the number of teeth on the third gear 203 is one-quarter, the third gear 203 rotates 90 degrees each time, which causes the third shaft 202 to drive all the first bevel gears 204 to rotate 90 degrees periodically. This causes the second bevel gear 205 to drive the second shaft 26 to rotate 90 degrees periodically, which in turn causes all the scraper pieces 27 to rotate 90 degrees periodically. This allows the scraper pieces 27 to periodically switch cleaning directions, enabling them to clean the inner wall of the electrolytic cell 3 in both horizontal and vertical directions, greatly improving the cleaning effect of the deposits on the inner wall of the electrolytic cell 3.

[0040] Furthermore, the scraper component 27 includes a blade holder 271. One side of the blade holder 271 is fixedly connected to a corresponding second rotating shaft 26, and the other side of the blade holder 271 is slidably connected to two parallel sliding rods 272. A blade 273, which abuts against the inner wall of the electrolytic cell 3, is fixedly connected to the end of each sliding rod 272 away from the blade holder 271. An installation groove 274 is provided on the inner side of the blade holder 271 to slide against the sliding rods 272. A connecting spring 275 is welded to one end of the inner side of the installation groove 274, and one end of the connecting spring 275 is welded to the sliding rod 272. The connecting spring 275 can apply elastic force to the sliding rod 272, making the blade 273 elastically contact the inner wall of the electrolytic cell 3, thereby ensuring that the blade 273 is always in close contact with the inner wall of the electrolytic cell 3, thus improving the cleaning effect on the deposits adhering to the inner wall of the electrolytic cell 3.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
