Description

Technical Field

[0001] This utility model relates to the field of electrolytic cells, specifically to a liquid level regulating device for electrolytic cell liquid. Background Technology

[0002] In actual production, the electrolyte level of the copper electrolytic cell needs to be precisely controlled according to the process flow. In the production sequence, the level needs to be adjusted to the high-flow circulation level, the power supply level, the lowering level, and the copper outlet level. The copper outlet level height should be consistent with the power supply level height. In order to adjust the corresponding liquid level height, there are relevant designs in the existing technology.

[0003] Patent document titled "An Electrolyte Level Adjustment Device" (Publication No. CN 208829772 U, hereinafter referred to as Document 1) discloses a related technical solution: It includes a level sleeve and an adjusting pipe inserted into the inner side of the top of the level sleeve, wherein the top of the level sleeve and the top of the adjusting pipe are provided with stepped notches. The electrolyte level adjustment device is fixed to the return pipe of the electrolyte, and the adjusting pipe is removed to adjust the lowest level of the electrolyte; the adjusting pipe is inserted into the level sleeve, and the stepped notch of the adjusting pipe is axially symmetrically aligned with the stepped notch of the level sleeve to adjust the second level of the electrolyte; by selecting a suitable notch arrangement, multi-level level adjustment can be achieved.

[0004] The shortcomings and defects of the solution provided in Reference 1 are as follows: the regulating tube is inserted into the liquid level sleeve and the upper end of the regulating tube also supports the upper crossbar of the exhaust pipe, which makes the rotation operation of the regulating tube extremely inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a liquid level regulating device for electrolytic cell liquid, which can accurately control the liquid level while conveniently adjusting the liquid level height.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a liquid level regulating device for an electrolytic cell liquid, characterized in that: it includes a cylindrical socket tube and a regulating tube, the outer circumferential surface of the middle part of the socket tube has a ring-shaped support platform, the upper end of the socket tube has a notch, the two ends of the bottom edge of the notch extend upward to the upper end face of the socket tube, the upper end of the regulating tube has an regulating notch, the regulating notch is a lower liquid level and an upper liquid level from bottom to top, the lower liquid level and the upper liquid level to the top of the regulating tube are stepped, the regulating tube is sleeved on the socket tube and the support platform supports the lower end of the regulating tube, the height of the upper end of the socket tube is between the upper liquid level and the top of the regulating tube.

[0007] The above technical solution solves the problem of difficulty in quickly and accurately adjusting the electrolyte level in the copper electrolytic cell when it is necessary to adjust it to different levels in different production stages. By rotating the regulating tube, the lower liquid-passing surface, the upper liquid-passing surface and the upper end face of the socket tube on the regulating tube respectively form the liquid-passing control surface to undertake the liquid level control task. The liquid level regulating device provided in this application can achieve accurate liquid level control without the need for any auxiliary tools and by manually rotating the regulating tube.

[0013] like Figure 1 , 2 As shown in Figure 3, a liquid level regulating device for an electrolytic cell includes a cylindrical socket tube 10 and a regulating tube 20. The outer circumferential surface of the middle part of the socket tube 10 has a ring-shaped support platform 11. A notch 12 is provided on the upper end of the socket tube 10. The two ends of the bottom edge 121 of the notch 12 have side edges 122 extending upward to the upper end face of the socket tube 10. The upper end of the regulating tube 20 has an regulating notch 21. The regulating notch 21 has a lower liquid level 211 and an upper liquid level 212 from bottom to top. The lower liquid level 211, the upper liquid level 212 and the top of the regulating tube 20 are stepped. The regulating tube 20 is sleeved on the socket tube 10 and the support platform 11 supports the lower end of the regulating tube 20. The height of the upper end of the socket tube 10 is between the upper liquid level 212 and the top of the regulating tube 20.

[0014] The above technical solution involves inserting the socket tube 10 into the drain pipe of the electrolytic cell, with the support platform 11 supporting the regulating tube 20. During liquid level adjustment, rotating the regulating tube 20 causes the regulating notch 21 on the regulating tube 20 to correspond to the notch 12 on the socket tube 10. This ensures the lower liquid level 211 is exposed, thus becoming the overflow surface for liquid level control, thereby establishing the control height for a large-flow circulating liquid level. Figure 1 As shown; when the lower liquid level 211 is blocked by the pipe wall next to the notch 12 on the socket tube 10, the upper liquid level 212 is exposed at the position of the notch 12 on the socket tube 10, as shown. Figure 2 As shown, the upper liquid surface 212 becomes the overflow surface for liquid level control, thus constituting the control height for the power supply liquid level or the copper outlet liquid level; as Figure 3 As shown, the regulating tube 20 is rotated further until its wall surrounds the notch 12 on the socket tube 10. The upper end of the socket tube 10, located at the regulating notch 21 of the regulating tube 20, becomes the control height for lowering the liquid level. Therefore, the solution provided in this application achieves the requirement for accurate control of the liquid level during copper electrolysis.

[0015] like Figure 1 , 2 As shown in Figure 3, the annular support platform 11 surrounds the outer circumference of the socket tube 10. The upper surface of the support platform 11 serves as the lower end face of the regulating tube 20, and the height positions of the lower liquid-passing surface 211 and the upper liquid-passing surface 212 on the regulating tube 20 are thus determined. In specific manufacturing, a small section of the tube blank used to make the regulating tube 20 can be cut and placed inside the socket tube 10, and then the two can be welded or bonded together. This can reduce the specifications of the blank tube preparation. At the beginning of processing, the length of the annular support platform 11 and the height positions of the lower liquid-passing surface 211 and the upper liquid-passing surface 212 are determined in a coordinated manner according to the height position of the upper end of the drain pipe of the electrolytic cell.

[0016] like Figure 1 As shown, the circumferential arc length of the bottom edge 121 is less than the circumferential arc length of the upper end face 213 of the regulating tube 20. This ensures that the rotating regulating tube 20 can completely block the notch 12 area on the socket tube 10, and only the upper end face of the socket tube 10 forms a liquid surface to control the liquid level.

[0017] like Figure 3 As shown, the height of the bottom edge 121 is equal to the height below the lower liquid level 211. This makes it easy to directly observe the position of the lower liquid level 211 when adjusting the liquid level, as the lower liquid level 211 is located on the regulating pipe 20, which serves as the outer pipe, resulting in a significant visual effect.

[0018] like Figure 2 , 3 As shown, the circumferential arc length of the bottom edge 121 is greater than or equal to the circumferential arc lengths of the lower liquid-passing surface 211 and the upper liquid-passing surface 212. By designing the circumferential arc length of the bottom edge 121 to be greater than or equal to both the lower liquid-passing surface 211 and the upper liquid-passing surface 212, it is ensured that the entire circumferential range of the lower liquid-passing surface 211 and the upper liquid-passing surface 212 is used for flow passage. This ensures the accuracy of liquid level height control and ease of operation.

[0019] Preferably, the outer wall of the socket tube 10 and the inner wall of the regulating tube 20 are in dynamic fit with a small gap. This allows for convenient adjustment of the rotating regulating tube 20, while the small gap does not affect the flow rate of each controlled liquid surface. That is, the flow rate of the small gap has almost no effect on the flow rate of the lower liquid surface 211, the upper liquid surface 212, and other liquid level control surfaces.
