[0024] Please refer to Figures 1 - 4As shown in the figure, the utility model provides a technical solution: a composite electroplating device based on low-temperature ionic liquid, which includes an electrolysis tank 1. The middle end of the bottom of the electrolysis tank 1 is fixedly connected with a liquid storage tank 2. A liquid guide pipe 6 with a manual valve body 7 arranged on its inner surface is communicated between the upper end on the right side of the liquid storage tank 2 and the lower end on the right side of the electrolysis tank 1. And a filter screen is fixedly connected to the inner side of one end of the liquid guide pipe 6 communicating with the electrolysis tank 1. A slag discharge pipe groove 18 is arranged at the lower end on the left side of the electrolysis tank 1, and a sealing cover is arranged at one end of the slag discharge pipe groove 18 away from the electrolysis tank 1. Fixed plates 4 are fixedly connected to both the left and right sides of the upper end of the electrolysis tank 1. A lifting motor 5 is fixedly installed at the bottom of the fixed plate 4. The output end of the lifting motor 5 is fixedly connected with a lifting threaded rod 13. A limit block is fixedly connected to the end of the lifting threaded rod 13 away from the lifting motor 5. An active plate 12 is threadedly connected to the upper end of the outer surface of the lifting threaded rod 13. One end of the bottom of the active plate 12 away from the lifting threaded rod 13 is fixedly connected with a connecting plate 8. The length of the connecting plate 8 is greater than the depth of the electrolysis tank 1. A frame plate 9 is fixedly connected to the bottom of the connecting plate 8. The frame plate 9 is movable inside the electrolysis tank 1. A first brush plate 21 adapted to the inner wall of the electrolysis tank 1 is fixedly connected to the outside of the frame plate 9. Limiting chute 24s are respectively arranged on the front and rear sides inside the frame plate 9. Tooth plates 22 are fixedly connected to both the front and rear ends of the top of the frame plate 9. A moving plate 25 is arranged at the right end inside the frame plate 9. Limiting sliders 23 slidably connected to the limiting chute 24s are fixedly connected to both the front and rear sides of the moving plate 25. A second brush plate 20 adapted to the bottom of the inner cavity of the electrolysis tank 1 is fixedly connected to the bottom of the moving plate 25. Driving motors 14 are fixedly installed at both the front and rear ends of the top of the moving plate 25. The output end of the driving motor 14 is fixedly connected with a driving gear 15 meshing with the tooth plate 22. A control switch 3 is fixedly installed at the left end of the front surface of the electrolysis tank 1. And the output end of the control switch 3 is electrically connected to the input ends of the lifting motor 5 and the driving motor 14 through wires respectively. A low-temperature ionic liquid 26 is arranged at the lower end of the inner cavity of the electrolysis tank 1.

[0025] Technical solution: Through the setting of the liquid guide pipe 6, when it is necessary to clean the inside of the electrolysis tank 1, the manual valve body 7 is opened, so that the low-temperature ionic liquid 26 in the electrolysis tank 1 enters the storage tank 2 for storage after being filtered by the filter screen at the upper end of the liquid guide pipe 6. Then, the sealing cover at one end of the slag discharge pipe groove 18 is removed. Then, the control switch 3 is used to turn on the lifting motor 5 to drive the lifting screw rod 13 to rotate. As a result, the movable plate 12 can move downward on the outer surface of the lifting screw rod 13, and the movement of the movable plate 12 can drive the frame plate 9 to enter the inside of the electrolysis tank 1 through the connecting plate 8. When the frame plate 9 enters the inside of the electrolysis tank 1, it can drive the first brush plate 21 to clean the inner wall of the electrolysis tank 1. When the frame plate 9 moves to the lower end of the inner cavity of the electrolysis tank 1 and the bottom of the second brush plate 20 contacts the bottom of the electrolysis tank 1, the control switch 3 is used to turn on the driving motor 14 to drive the driving gear 15 to rotate.

Embodiment

[0026] On the basis of Embodiment 1, the present utility model is as Figures 2 - 4 shown, and a pump 19 is fixedly installed at the middle end of the bottom of the inner cavity of the storage tank 2, and the liquid outlet end of the pump 19 is communicated with the upper end at the rear side of the electrolysis tank 1 through a pipeline.

[0027] Technical solution: Through the setting of the pump 19, after the inside of the electrolysis tank 1 is cleaned, and at the same time the manual valve body 7 is closed and the sealing cover is reinstalled at one end of the slag discharge pipe groove 18, the external controller is used to turn on the pump 19. Then, the pump 19 can send the low-temperature ionic liquid 26 in the storage tank 2 back into the electrolysis tank 1 again, which is convenient for the reuse of the low-temperature ionic liquid 26 (Low-temperature ionic liquids, such as room temperature ionic liquids, have some unique physical and chemical properties, such as high working voltage, low volatility, non-toxic and safer than organic electrolytes. However, ionic liquids have low ionic conductivity, high viscosity and high melting point, resulting in poor performance at low temperatures. In order to improve this performance, researchers compounded the solvent γ-butyrolactone (GBL) with the ionic liquid EMIMBF4 to obtain a new electrolyte without melting point and a glass transition temperature as low as -126°C, thus significantly improving its performance in low-temperature environments. This discovery shows that the performance of low-temperature ionic liquids can be improved through technical means without frequent liquid replacement). Embodiment
