DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0029] In the description of the present invention, unless otherwise specified, the terms "upper", "lower", etc., indicating the orientation or state relationship are based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention will be understood according to specific circumstances.

[0031] like Figure 1-4 As shown, the zinc electrolyte circulation purification device includes a connecting tank 1, a distribution tank 2, a buffer tank A3, a buffer tank B4 and a slag discharge tank 15.

[0032] The connecting groove 1 is a U-shaped groove, and the distributing groove 2 is a square groove. The groove depth of the distributing groove 2 is greater than that of the connecting groove 1. The connecting groove 1 is arranged in the distributing groove 2. The bottom of the connecting groove 1 is provided with a supporting rib 18. The area between the connecting groove 1 and the distributing groove 2 is the distributing area 5. The buffer groove A is connected to the left side of the connecting groove 1 and the distributing groove 2 (with the attached Figure 1 , and an upper baffle 11 and a lower baffle 12 are respectively provided between the buffer tank A and the distribution area 5; a defoaming assembly is provided between the connecting tank 1 and the buffer tank A. The zinc electrolysis circulating liquid first enters the connecting tank 1, and enters the buffer tank A3 after the organic foam floating on the surface is blocked by the defoaming assembly. Although the buffer tank A3 is connected to the distribution area 5, the bottom slag sinks to the bottom of the buffer tank A due to the setting of the lower baffle 12, avoiding or reducing the bottom slag from entering the distribution area 5; at the same time, the setting of the upper baffle 11 also blocks the surface foam from entering the distribution area 5 from the buffer tank A, thereby realizing the open circuit of the foam and the bottom slag in the zinc electrolysis circulating liquid, reducing the enrichment of organic foam and crystal slag in the zinc electrolysis circulating liquid, and reducing or avoiding the enrichment of organic foam and crystal slag in the zinc electrolyte and the influence on the electrolysis efficiency and product quality. The distribution area 5 is provided with a siphon tube 6, which is arranged on the same side, making the overall structure of the utility model more compact. One end of the siphon tube 6 is connected to the distribution area 5, connected by a round nut, and the inlet pipe is upward; the other end is a 90° elbow, and the bottom pipe mouth extends to the top of the electrolytic cell to deliver the circulating electrolyte in the distribution area 5 into the electrolytic cell.

[0033] The defoaming assembly includes a positioning plate 7, a connecting screw 8, an overflow plate 9 and a guide plate 10; the overflow plate 9 and the guide plate 10 are integrally connected to form an inverted V-shaped structure with a high middle and low sides, and a reinforcing rib plate 21 is connected to the bottom; the overflow plate 9 and the guide plate 10 are connected to the positioning plate 7 through the connecting plate 8; the positioning plate 7 is fixed above the distribution groove 2 by means of a support rod (or direct welding), and the height of the overflow plate 9 and the guide plate 10 can be adjusted by adjusting the upper nut of the connecting screw 8 to adapt to the change of the liquid level in the connecting groove 1, so that the overflow plate 9 and the guide plate 10 can be adjusted to block the organic foam on the surface of the electrode liquid.

[0034] The foam floats on the surface of the electrolyte. When the electrolyte in the connecting tank 1 flows through the defoaming component, the through holes opened by the overflow plate 9 and the guide plate 10 allow the liquid to flow through, but the foam is blocked. Normally, the foam will be blocked on the right side of the overflow plate 9. The inventor has tried to set the overflow pipe 20 on the right side of the overflow plate 9 and slightly higher than the overflow plate 9. However, in actual use, due to the fluctuation of the liquid level in the connecting tank 1, a large amount of electrolyte is also discharged from the overflow pipe 20. To solve this problem, a U-shaped overflow tank 19 with the same height as the guide plate is set in the buffer tank A3 and close to the guide plate 10, so that the blocked foam can turn over the defoaming component and enter the overflow tank 19, and be discharged from the electrolyte circulation system through the overflow pipe 20, thereby achieving the removal of organic foam while avoiding the loss of electrolyte. Without affecting the normal circulation of the electrode liquid, the problem of organic enrichment in the electrolyte is solved.

[0035] The buffer tank B4 is arranged beside the buffer tank A3 and is connected to the buffer tank A3. The depth of the buffer tank B4 is greater than that of the buffer tank A3. Due to the height difference between the two, the bottom slag is more likely to enter the buffer tank B4. As a preferred solution, the bottom of the buffer tank A3 is provided with a slag discharge inclined plate 14 that is inclined toward the buffer tank B4, so that the bottom slag is more likely to enter the buffer tank B4 and avoid accumulation of the bottom slag in the buffer tank A3.

[0036] A slag discharge tank 15 is provided below the buffer tank B4; a slag inlet gate 16 is provided between the slag discharge tank 15 and the buffer tank B4; and a slag discharge gate 17 is provided at the bottom of the slag discharge tank 15. The slag inlet gate 16 and the slag discharge gate 17 are respectively equipped with control motors. By opening the slag inlet gate 16, the slag in the buffer tank B4 is discharged into the slag discharge tank 15, and by opening the slag discharge gate 17, the crystallized slag in the slag discharge tank 15 is discharged from the zinc electrolyte circulation system. A rubber sealing surface is provided between the slag inlet gate 16 and the slag discharge gate 17 and the tank wall of the slag discharge tank 15, which is actually equivalent to providing two gate valves in the slag discharge tank 15. The opening or closing of the slag inlet gate 16 and the slag discharge gate 17 is controlled by a control motor. As a preferred solution, a control program can be provided in the control motor, and the opening frequency of the slag inlet gate 16 and the slag discharge gate 17 is set by the control program to realize timed slag discharge.

[0037] According to the on-site layout structure of the electrolyte circulation system, the overall structure of the utility model is arranged at a high position, so there is enough space to set the slag discharge trough 15. In order to facilitate the discharge of the slag collected in the slag discharge trough 15, the bottom of the slag discharge trough 15 is set as a flange connection port, and is connected to the slag collecting trough at the production site through a pipeline.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
