Technical Field

[0001] The invention relates to the technical field of cobalt electrolytic cells, and in particular to a cell diaphragm frame for cobalt electrolytic cells. Background Art

[0002] Electrowinning refers to the process of electrolytically depositing a solution containing metal ions after extraction and enrichment to produce cathode metal in hydrometallurgy. The copper concentration of the electrolytic inlet solution is generally 45-50 g / I, and the copper concentration of the solution after electrolysis is 30-35 g / I.

[0019] The beneficial effects of the present invention are:

[0020] Through the height adjustment mechanism provided in the present invention, the problems of difficult height adjustment of the diaphragm frame, low positioning accuracy, and easy wear of components caused by traditional wooden wedge fixation are effectively avoided. During use, the operator drives the first screw to rotate by rotating the handle, driving the first sliding seat to move horizontally in the chute. At this time, the push plate and the moving seat are linked, and through the guiding action of the support plate and the first slide rail, the horizontal movement is converted into the vertical lifting of the support, ensuring that the distance between the diaphragm frame and the electrolytic cell meets the process requirements, and improving the stability and efficiency of the cobalt electrowinning process;

[0021] Through the diaphragm frame assembly provided in the present invention, the problems of cumbersome disassembly and assembly and low maintenance efficiency of traditional fixed diaphragm frames are effectively avoided. During use, through the guiding action of the second slide rail, the outer frame can slide horizontally along the top of the support, and the inner frame can be vertically pulled out through the handle. When the diaphragm needs to be replaced, the operator only needs to pull the handle to lift the inner frame out of the electrolytic cell as a whole, without removing the entire frame structure. The grid design provides a uniform support surface for the diaphragm while ensuring the fluidity of the electrolyte, thus greatly shortening the time for maintaining and replacing the diaphragm and reducing the operation difficulty and labor intensity;

[0022] Through the spacing adjustment mechanism provided in the present invention, the problem of non-adjustable electrode spacing is effectively avoided. After starting the motor, the second screw is driven to rotate through the transmission assembly, driving the threaded seat to move along the fourth slide rail. The lifting movement of the adjustment plate forces the spacing adjustment groove to change its angle, and the vertical movement is converted into the horizontal displacement of the outer frame through the guiding column, ensuring accurate adjustment of the spacing of the diaphragm frame assembly. Therefore, the requirements for electrode spacing in different electrowinning processes are met, and the adaptability and flexibility of the cobalt electrowinning process are improved;

[0023] Through the scale assembly provided in the present invention, the pointer is fixed at the bottom of the support and corresponds to the scale inside the electrolytic cell. When the height of the support changes, the pointer moves on the scale, showing the current height value, which is convenient for the operator to accurately judge the height position of the diaphragm frame.

A chute 304 is fixedly arranged on one side of the support plate 303 close to the first slide rail 310. The height of the bracket 301 is adjusted by a first driving component at the top of the first slide rail 310. The first driving component includes a moving seat 307 movably arranged at the top of the first slide rail 310. A push plate 305 is fixedly arranged on one side of the moving seat 505307 corresponding to the support plate 303. A first sliding seat 306 which slides inside the chute 304 is fixedly arranged on one side of the push plate 305. A first screw rod 308 is arranged in the first sliding seat 306 in a threaded transmission manner. A rotating handle 309 is fixedly arranged at the end of the first screw rod 308. During use, an operator drives the first screw rod to rotate by rotating the rotating handle, driving the first sliding seat to move horizontally in the chute. At this time, the push plate and the moving seat are linked.

The transmission assembly 512 is composed of a belt pulley and a belt. The second screw rod is driven to rotate through the transmission assembly, and the threaded seat is driven to move along the fourth slide rail. The lifting movement of the adjustment plate forces the spacing adjustment groove to change the angle, and the vertical movement is converted into the horizontal displacement of the outer frame through the guide post to ensure the accurate adjustment of the spacing of the diaphragm frame assembly.

[0039] Embodiment 1: A transparent glass 2 is fixedly arranged inside the electrolytic cell 1. A scale assembly for observing the lifting distance is installed on one side corresponding to the transparent glass 2 between the electrolytic cell 1 and the bracket 301. The scale assembly includes a pointer 312 fixedly arranged at the bottom of the bracket 301 and a scale 313 fixedly arranged inside the electrolytic cell 1. The pointer 312 and the scale 313 correspond to each other. The pointer is fixed at the bottom of the bracket and corresponds to the scale inside the electrolytic cell. When the height of the bracket changes, the pointer moves on the scale to display the current height value, which is convenient for the operator to accurately judge the height position of the diaphragm frame.

[0040] Embodiment 2: The first screw rod 308 is rotatably arranged inside the electrolytic cell 1 through a support seat 311. Four lifting columns 302 are symmetrically arranged and are respectively located at the four corners between the bracket 301 and the electrolytic cell 1, so that the bracket has stability during the lifting process. Grids 404 are fixedly arranged inside both the outer frame 401 and the inner frame 403, ensuring the fluidity of the electrolyte while providing a uniform support surface for the diaphragm.

[0041] Embodiment 3: The second slide rail 402 is symmetrically and fixedly arranged at the top of the bracket 301. At the top of the inner frame 403, handles 405 are symmetrically and fixedly arranged. The inner frame can be vertically pulled out through the handles (405). The guide posts 509 are adapted to the spacing adjustment grooves 507 and are movably arranged. The support arms 508 are movably arranged outside the third slide rail 502. The lifting movement of the adjustment plate (506) forces the spacing adjustment grooves (507) to change in angle, so as to achieve the function of spacing adjustment.

[0042] Working principle: The operator rotates the rotary handle 309 to drive the first screw rod 308 to rotate, so that the first sliding seat 306 moves horizontally in the sliding groove 304. The push plate 305 is linked with the moving seat 307. Through the guidance of the support plate 303 and the first slide rail 310, the horizontal movement is converted into the vertical lifting of the bracket 301, ensuring that the spacing between the diaphragm frame and the electrolytic cell 1 meets the process requirements. The diaphragm frame assembly 4 includes an outer frame 401 and an inner frame 403. The outer frame 401 is placed on the second slide rail 402 and can slide horizontally along the top of the bracket. The inner frame 403 can be vertically pulled out through the handle 405, which is convenient for replacing the diaphragm. The grid 404 is designed to ensure the fluidity of the electrolyte and provide uniform support for the diaphragm. The spacing adjustment mechanism 5 adjusts the electrode spacing through the second drive assembly. The motor 511 drives the second screw rod 510 to rotate, driving the threaded seat 505 to move along the fourth slide rail 503. The adjustment plate 506 moves up and down, forcing the spacing adjustment grooves 507 to change in angle. The guide posts 509 convert the vertical movement into the horizontal displacement of the outer frame 401, realizing the accurate adjustment of the spacing of the diaphragm frame assembly. The scale assembly includes a pointer 312 and a scale 313, which are used to observe the lifting distance. The pointer is fixed at the bottom of the bracket and corresponds to the scale, displaying the current height value, which is convenient for the operator to accurately judge the height position of the diaphragm frame.
