Description

Technical Field

[0001] The present invention relates to the field of precious metal preparation devices, and particularly to an apparatus for preparing precious metal nanomaterials by an ultrasonic electrochemical method. Background Art

[0002] The electrochemical method mainly refers to cathodic protection, that is, a method of sacrificing an anode to protect the cathode, so that the metal to be protected becomes the cathode and is protected. For example, for underground pipelines or chemical equipment, a metal block can be used as the anode and connected to it, and current is passed through for protection.

[0003] As in the prior art, Chinese Patent Application No. 201810848067.9 201420678819.9, an apparatus for preparing precious metal nanomaterials by an ultrasonic electrochemical method, which includes an electrolytic cell cover, a cell cover, a cathode guide rod, a cathode, an electrolyte, water, a housing, an ultrasonic generator, a cell body, an anode, an anode guide rod, and an electrolytic cell. The cell body is covered with a cell cover. Water and an electrolytic cell are installed inside the cell body. A circulating electrolyte inlet and an electrolyte outlet are provided on the side wall of the electrolytic cell. An ultrasonic generator is installed on the outer side wall of the cell body. The electrolytic cell is arranged in the water in the cell body. The electrolytic cell cover is covered on the upper part of the electrolytic cell. An air inlet and an air outlet are provided on the electrolytic cell cover. The cathode guide rod, the cathode, the electrolyte, the anode, and the anode guide rod are all arranged inside the electrolytic cell. The anode guide rod and the cathode guide rod are respectively connected to the positive and negative electrodes of the power supply. This solution is simple to operate, and each parameter is easy to control. By controlling the parameters of the device, the size and shape of the nanoparticles can be effectively controlled. It is suitable for preparing precious metal nanoparticles.

[0004] If the electrolytic cell is too large, when collecting precious metal nanomaterials, a large amount of precious metal nanomaterials will remain in the electrolytic cell. If multiple water rinses are used to take out the precious metal nanomaterials, a large amount of manpower is required, which is not convenient for industrial high-efficiency operation. Therefore, we designed an apparatus that can efficiently take out the prepared precious metal nanomaterials, and the device is automated and convenient for personnel to operate.

Detailed implementation manners

[0018] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention. Embodiment

[0019] With key reference to Figures 1-9 , a vertical plate 2 is fixedly connected to the top left of the bottom plate 1, a top plate 3 is fixedly connected to the top right of the vertical plate 2, two first connecting plates 4 are fixedly connected to the bottom of the top plate 3, and a baffle 5 is fixedly connected to the common bottom of the two first connecting plates 4.

[0020] A motor mounting plate 25 is fixedly connected to the right side of the vertical plate 2. A first rotating column 27 is rotatably connected to the motor mounting plate 25. A first gear 26 is fixedly connected to the outer wall of the first rotating column 27. A servo motor 28 is fixedly installed on the motor mounting plate 25, and the power output end of the servo motor 28 is connected to the first rotating column 27.

[0021] At least two auxiliary guide plates 53 are fixedly connected to the right side of the vertical plate 2. The limit sliding column 18 is vertically limited and slidably connected to the auxiliary guide plates 53, so that the limit sliding column 18 can only be vertically slidably connected. A first rack 29 is fixedly connected to the left side of the limit sliding column 18, and the first rack 29 meshes with the first gear 26. That is, starting the servo motor 28 can make the limit sliding column 18 move up and down.

[0022] A housing 6 is fixedly connected to the top of the bottom plate 1. An ultrasonic generator 12 is fixedly installed on the outer wall of the bottom of the housing 6, so that ultrasonic vibration can be carried out in the housing 7 to drop the precious metal nanomaterials generated on the cathode 13 into the electrolytic cell 16.

[0023] A first water inlet pipe 9 is installed on the left side of the housing 7 near the top. The first water inlet pipe 9 penetrates through the housing 6 and extends to the outside, so that the first water inlet pipe 9 can conduct water into the housing 7, and a valve is installed on the first water inlet pipe 9. A first water outlet pipe 8 is installed on the right side of the housing 7 near the bottom. The first water outlet pipe 8 penetrates through the housing 6, and the outer end is located outside the housing 6. A valve is also installed on the first water outlet pipe 8. Water is placed in the housing 7 to facilitate ultrasonic vibration of the precious metal nanomaterials on the cathode 13. Water is put in from the first water inlet pipe 9 and discharged from the first water outlet pipe 8.

[0024] An electrolytic cell 16 is fixedly installed or stably placed in the housing 7, so that the electrolytic cell 16 is placed in the housing 7. A second water inlet pipe 34 is installed on the left side of the electrolytic cell 16 near the top. The second water inlet pipe 34 is located on the top of the housing 7, and a valve is provided on the second water inlet pipe 34. A second water outlet pipe 14 is installed on the right side of the electrolytic cell 16 near the bottom. A valve is installed on the second water outlet pipe 14. An electrolyte is applied at the second water inlet pipe 34, and then when the electrolyte needs to be discharged, it is discharged from the second water outlet pipe 14. In order not to pollute the housing 7, a discharge pipe can be installed at the second water outlet pipe 14, and the outside of the discharge pipe is inserted into the first water outlet pipe 8, so that when the electrolyte needs to be discharged, it is discharged from the second water outlet pipe 14 to the first water outlet pipe 8. Or a water pump is connected to the second water outlet pipe 14 for pumping water.

[0025] A heavy cover plate 10 with a relatively heavy weight is placed on the top of the electrolytic cell 16. A first chute 11 is opened at the center of the bottom of the heavy cover plate 10. Sealing blocks 33 are fixedly connected to both sides of the top of the electrolytic cell 16. The sealing blocks 33 can seal the first chute 11, so that the heavy cover plate 10 can stably seal the top of the electrolytic cell 16. Coupled with the sealing of the valve, a relatively sealed environment is formed in the electrolytic cell 16. A protective gas is introduced into the second water inlet pipe 34, and then at this time, through mechanisms such as a motor, the heavy cover plate 10 is slightly higher than the electrolytic cell 16. When passing the protective gas, the air is discharged through the top of the electrolytic cell 16, and then through mechanisms such as a motor, the heavy cover plate 10 is pressed on the electrolytic cell 16, so that almost only the protective gas remains inside. The sealing block 33 just plugs at the first chute 11, sealing both sides of the first chute 11. Almost only the protective gas remains in the electrolytic cell 16, thus facilitating the electrolysis reaction.

[0026] Two guide rods 52 are fixedly installed on the heavy cover plate 10. The bottom parts of the two guide rods 52 are respectively fixedly installed with an anode 17 and a cathode 13. When the heavy cover plate 10 is placed on the electrolytic cell 16, the anode 17 and the cathode 13 are placed in the electrolyte in the electrolytic cell 16. By applying positive electricity to the anode 17 and negative electricity to the cathode 13, an electrolytic chemical reaction is carried out in the electrolyte in the electrolytic cell 16.

[0027] The bottom of the above-mentioned limit sliding column 18 is connected to the heavy cover plate 10 in a vertically limited sliding manner, and it is a sealed limit sliding connection. A rubber pad is arranged in the chute on the heavy cover plate 10 so that gas will not leak out.

[0028] The limit sliding column 18 leans against the left inner wall of the electrolytic cell 16 and is slidably connected to the left inner wall of the electrolytic cell 16.

[0029] A auxiliary bottom bar 19 is fixedly connected to the right side of the bottom of the limit sliding column 18. Two hinge rods 20 are hinged to the top of the auxiliary bottom bar 19. The other sides of the two hinge rods 20 away from the auxiliary bottom bar 19 are hinged to the first cross plate 22. A spring 21 is fixedly connected between the first cross plate 22 and the auxiliary bottom bar 19. The spring 21 is a mechanism that can keep the first cross plate 22 above the auxiliary bottom bar 19. Due to the restraining force of the spring 21, the first cross plate 22 and the auxiliary bottom bar 19 can stably maintain a parallel state. Multiple springs 21 can be adopted to better restrain the first cross plate 22 above the auxiliary bottom bar 19.

[0030] A filter funnel 15 is connected to the top of the first cross plate 22. The left side of the filter funnel 15 leans against the right side of the limit sliding column 18, so that the filter funnel 15 can be stably translated to the right in the later stage. And the right side of the filter funnel 15 is also ideally in contact with the left side of the electrolytic cell 16. In order to make the filter funnel 15 better return to the electrolytic cell 16, there is a certain distance between the right side of the filter funnel 15 and the left inner wall of the electrolytic cell 16. Thus, it is convenient for the filter funnel 15 to return to the electrolytic cell 16. The filter funnel 15 is placed directly below the anode 17 and the cathode 13. The cross-sectional area of the top opening of the filter funnel 15 almost includes the cross-sectional area of the electrolytic cell 16, that is, the cross-sectional area of the filter funnel 15 is slightly smaller than the cross-sectional area of the electrolytic cell 16.

[0031] Two roller mounting plates 32 are fixedly connected to the top of the filter funnel 15. The top of the two roller mounting plates 32 is rotatably connected with a first roller 31. The first roller 31 is limited to roll in the first chute 11 of the heavy cover plate 10. And the first roller 31 is always pressed against the first chute 11 in the heavy cover plate 10, so that the upward moving filter funnel 15 drives the heavy cover plate 10 to move upward through the roller mounting plates 32 and the first roller 31. Since the heavy cover plate 10 is limited by the limit sliding column 18, the heavy cover plate 10 can only move up and down.

[0032] The baffle 5 is placed directly above the heavy cover plate 10.

[0033] When driving the servo motor 28 to act, at this time, the first gear 26 meshes with the first rack 29, driving the limit sliding column 18 to move upward. When the filter funnel 15 is moved out of the electrolytic cell 16 by a preset distance, at this time, the heavy cover plate 10 is pressed against the bottom of the baffle 5. At this time, the limit sliding column 18 continues to move upward. At this time, the first roller 31 rolls in the first chute 11. At this time, the hinge rod 20 is inclined and the spring 21 is stretched. At this time, the auxiliary bottom strip 19 that continues to move upward causes the filter funnel 15 to move to the right. At this time, the heavy cover plate 10 no longer moves, so that the filter funnel 15 is placed on the right side of the electrolytic cell 16. At this time, it is convenient to take out the precious metal nanomaterials in the filter funnel 15. And when the ultrasonic generator 12 is not in use, the state of the precious metal nanomaterials formed on the cathode 13 can be observed by raising the limit sliding column 18, which is convenient for personnel to study various data of the electrolytic chemical reaction.

[0034] Embodiment 2: On the basis of Embodiment 1, the technical effect of facilitating self-cleaning of the electrolytic cell 16 is added.

[0035] The filter funnel 15 is in the shape of a conical funnel, and filter holes are evenly distributed on the outer wall of the filter funnel 15, which can filter the electrolyte but not the precious metal nanomaterials. That is, the precious metal nanomaterials will be placed on the inner wall of the filter funnel 15.

[0036] A cylinder 47 is fixedly installed at the bottom of the filter funnel 15. The cylinder 47 is open at the top and bottom. The filter funnel 15 is also open at the top and bottom, and the top of the cylinder 47 is communicated with the bottom of the filter funnel 15. A cap 46 is installed at the bottom of the cylinder 47. The cap 46 can be stuck on the outer wall of the cylinder 47 or can be threadedly connected to the bottom of the cylinder 47, so that the cap 46 can block the bottom of the cylinder 47 and is convenient for disassembly. When the ultrasonic generator 12 is started, the precious metal nanomaterials formed on the cathode 13 are mixed into the electrolyte in the electrolytic cell 16. When discharging the electrolyte in the electrolytic cell 16, at this time, the precious metal nanomaterials are placed on the inner wall of the filter funnel 15 or in the cylinder 47.

[0037] The outer wall of the cylinder 47 is rotationally connected with a limit rotating cylinder 45 in a limited way. A second bevel gear 44 is fixedly connected to the outer wall of the limit rotating cylinder 45 near the bottom.

[0038] A second auxiliary ring plate 41 is fixedly connected to the outer wall of the limit rotating cylinder 45 near the top. A plurality of stirring extension rods 40 are evenly distributed at the bottom of the second auxiliary ring plate 41, which are used for stirring the electrolyte in the electrolytic cell 16 when the second auxiliary ring plate 41 rotates.

[0039] A vertical plate 23 is fixedly connected to the left top of the first horizontal plate 22. A first auxiliary ring plate 24 is fixedly connected to the right side of the vertical plate 23 near the top. The first auxiliary ring plate 24 is also fixedly connected to the outer wall of the cylinder 47.

[0040] A second rotating column 35 and a third rotating column 36 are rotatably connected to the vertical plate 23. A second gear 37 is fixedly connected to the outer wall of the middle part of the second rotating column 35, and a first bevel gear 43 is fixedly connected to the outer wall on the right side of the second rotating column 35. The first bevel gear 43 meshes with a second bevel gear 44. A third gear 39 is fixedly connected to the outer wall of the third rotating column 36, and the third gear 39 meshes with the second gear 37. A second rack 38 is fixedly connected to the inner wall of the electrolytic cell 16, and the third gear 39 meshes with the second rack 38. It is used to drive the limit rotating cylinder 45 to rotate when the limit sliding column 18 moves up or down, so as to drive the second auxiliary ring plate 41 and the stirring extension rod 40 to rotate, so that the electrolyte in the electrolytic cell 16 can be automatically stirred.

[0041] The other structures of the second embodiment are the same as those of the first embodiment.

[0042] Embodiment 3: On the basis of Embodiment 2, technical means are added to enable the electrolyte to flow out quickly and facilitate the extraction of noble metal nanomaterials.

[0043] A plurality of arc-shaped convex plates 42 are fixedly connected to the top of the second auxiliary ring plate 41, and the plurality of arc-shaped convex plates 42 are circumferentially distributed on the outer periphery of the cylinder 47.

[0044] A plurality of first limit sliding grooves 50 are circumferentially distributed on the first auxiliary ring plate 24. A sliding strip 48 is connected to the plurality of first limit sliding grooves 50 in a vertically limited sliding manner. A rubber ball 49 is fixedly installed at the top of the sliding strip 48. The bottom of the sliding strip 48 is rotatably connected to a second roller 51, and the second roller 51 rolls on the plurality of arc-shaped convex plates 42, so that the rubber ball 49 moves up and down intermittently. The rubber ball 49 moves upward and impacts the outer wall of the filter funnel 15. Thereby, the noble metal nanomaterials move into the cylinder 47, or the noble metal nanomaterials do not block the filter holes on the filter funnel 15, so that the electrolyte leaks out better and faster, so as to facilitate the integrated and efficient extraction of the noble metal nanomaterials. Moreover, such impact vibration also facilitates the extraction of the noble metal nanomaterials placed on the outer wall of the filter funnel 15.

[0045] The other structures of the third embodiment are the same as those of the second embodiment.

[0046] In specific implementation, first pour water into the tank body 7, and then pour electrolyte into the electrolytic cell 16. At this time, start the servo motor 28 to rotate the first gear 26. The first gear 26 meshes with the first rack 29, causing the limit sliding column 18 to move downward. At this time, make the heavy cover plate 10 slightly higher than the top of the electrolytic cell 16. At this time, introduce a protective gas at the second water inlet pipe 34. After introducing the protective gas for a preset time, start the servo motor 28 to move the limit sliding column 18 downward to cover the top of the electrolytic cell 16. At this time, the electrolytic cell 16 is in a sealed state through the cooperation of the sealing block 33. At this time, apply positive and negative electricity to the anode 17 and the cathode 13 respectively, causing an electrochemical reaction in the electrolyte in the electrolytic cell 16. At this time, noble metal nanomaterials are generated on the cathode 13. After the electrochemical reaction reaches the preset time, stop supplying positive and negative electricity.

[0047] At this time, start the ultrasonic generator 12 to mix the noble metal nanomaterials on the cathode 13 into the electrolyte in the electrolytic cell 16. After the ultrasonic generator 12 is started for a preset time, at this time, open the valve on the second water outlet pipe 14, and drain the electrolyte in the electrolytic cell 16 through an external water pump or pipeline. At this time, the noble metal nanomaterials are placed on the filter funnel 15. After the water pump is started for a preset time, then start the servo motor 28 to move the limit sliding column 18 upward, driving the filter funnel 15, the heavy cover plate 10, the cathode 13, and the anode 17 to move upward. When the heavy cover plate 10 abuts against the baffle 5, at this time, the heavy cover plate 10, the cathode 13, and the anode 17 no longer move. At this time, the filter funnel 15 is also placed at a preset position on the top of the electrolytic cell 16. At this time, under the cooperation of the first roller 31 and the hinge rod 20, the filter funnel 15 moves to the right, enabling personnel to take out the noble metal nanomaterials in the filter funnel 15.

[0048] After taking out the noble metal nanomaterials, at this time, move the limit sliding column 18 downward. At this time, under the action of the spring 21, the first cross plate 22 first returns to the state directly above the initial auxiliary bottom strip 19, and then gradually moves into the electrolytic cell 16. Thus, the device returns to its initial state completely.

[0049] This device has multiple working effects: the effect of self-cleaning the inside of the electrolytic cell 16, the effect of efficient leakage of the electrolyte, the effect of automatic collection of high-efficiency noble metal nanomaterials, the effect of facilitating the extraction of noble metal nanomaterials, and the effect of facilitating the observation of the forming state of the noble metal nanomaterials on the cathode 13.

[0050] After electrolysis is completed, the ultrasonic generator 12 is started for a preset time at this time, so that foreign objects will not be firmly adsorbed on the electrolytic cell 16. At this time, the servo motor 28 is started to move the limit sliding column 18 upward. The upward-moving limit sliding column 18 drives the third gear 39 to engage with the second rack 38. Through the engagement of the second gear 37 and the third gear 39, and the engagement of the first bevel gear 43 and the second bevel gear 44, the limit rotating cylinder 45 rotates. The rotating limit rotating cylinder 45 drives the second auxiliary ring plate 41 and the stirring extension rod 40 to rotate. The rotating second auxiliary ring plate 41 and stirring extension rod 40 stir the solution in the electrolytic cell 16. The mixed solution is pumped out from the second water outlet pipe 14 by an external water pump. At this time, there are no fixed impurities in the electrolytic cell 16, achieving self-cleaning of the electrolytic cell 16.

[0051] When the limit sliding column 18 moves upward, the filter funnel 15 will be moved outside the electrolytic cell 16. However, sometimes the electrolyte cannot leak out of the filter funnel 15 quickly, and the electrolyte will leak outside, which is not reasonable. And this device is an integrated automatic device with coherent actions and will not wait slowly for the electrolyte in the filter funnel 15 to leak out slowly. The upward-moving limit sliding column 18 drives the second auxiliary ring plate 41 to rotate, and the second auxiliary ring plate 41 drives the arc-shaped convex plate 42 to rotate. At this time, the second roller 51 rolls on the arc-shaped convex plate 42, causing each rubber ball 49 to intermittently hit the outer wall of the filter funnel 15, so that the filter holes on the outer wall of the filter funnel 15 will not be blocked by the noble metal nanomaterials, thereby accelerating the leakage of the electrolyte from the filter holes on the outer wall of the filter funnel 15. When discharging the electrolyte, the limit sliding column 18 can be moved upward at the same time, so that the noble metal nanomaterials move into the cylinder 47 under the assistance of vibration and water, facilitating collection. Thus, the device can efficiently and integrally and highly safely take out the noble metal nanomaterials. And the sliding bar 48 that moves up and down can also better mix the electrolyte, thus better self-cleaning the electrolytic cell 16. The sliding bar 48 that moves up and down and the stirring extension rod 40 for stirring can also act according to the actual situation, facilitating better electrochemical reactions.

[0052] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
