Description

Technical Field

[0001] The utility model belongs to the technical field of electrolysis equipment, and relates to a soluble anode diaphragm electrolytic cell with precise positioning. Background Technique

[0002] In the production process of soluble anode diaphragm electrolytic nickel, in the traditional electrolytic cell diaphragm frame, spacer sleeves with different lengths are placed at intervals, and titanium rods are inserted into the diaphragm frame ears for fixation to assemble into a diaphragm frame group. An electrolytic cell requires four to five groups of diaphragm frames. After the diaphragm frame group is lowered into the electrolytic cell, wooden wedges are driven in at multiple points on the upper part of the diaphragm frame group and both sides of the electrolytic cell for fixation. The lower part of the diaphragm frame is only supported by legs, lacking other fixation measures. If electric nickel sticks to the bag or the anode plate rubs during the charging and discharging operation, it is easy to cause the diaphragm frame to tilt, and in severe cases, the diaphragm frame will be pulled out. In addition, under the action of electrolyte acid corrosion and temperature, the spacer sleeves are aged to varying degrees with the extension of the use time, resulting in different sizes of the pole pitch, which increases the difficulty of the charging and discharging operation. In addition, due to the influence of the slope at the bottom of the electrolytic cell, it is very difficult to level the diaphragm frames of the whole cell, resulting in a small liquid level difference between the middle anode and cathode in the electrolytic cell and a large liquid level difference between the anode and cathode at the head and tail sides, leading to easy acid leaching and fracture of the copper ear wires of the middle anode plates and too high residual anode rates at the head and tail sides.

Along the length direction of the positioning plate, there are multiple clamping groups. Each clamping group includes a through-rod slot and a diaphragm frame socket. On both sides of the electrolytic cell body in the length direction, there is a positioning waist plate each. The positioning waist plate is located in the middle of the electrolytic cell body and is arranged along the length direction of the electrolytic cell body. Along the length direction of the positioning waist plate, there are multiple diaphragm frame slots corresponding to the diaphragm frame sockets one by one. Below the positioning waist plate, there is a diaphragm frame leg slot arranged horizontally along the length direction of the electrolytic cell body.

Specific Embodiments

[0016] The following will describe the present utility model in detail with reference to the drawings:

[0017] Such as Figure 1As shown in the figure, a soluble anode diaphragm electrolytic cell with precise positioning includes an electrolytic cell body 1. The electrolytic cell body 1 can adopt an existing conventional electrolytic cell body. On both sides of the electrolytic cell body 1 in the length direction, there is a horizontally arranged positioning plate 2 each. The positioning plate 2 is located above the electrolytic cell body 1 and is arranged along the length direction of the electrolytic cell body 1. Along the length direction of the positioning plate 2, there are multiple clamping groups 3 on the positioning plate 2. The clamping group 3 includes a rod-passing slot 301 and a diaphragm frame socket 302. The rod-passing slot 301 is used for positioning the rod, and the diaphragm frame socket 302 is used to clamp the edge of the diaphragm frame into the diaphragm frame socket 302 for positioning and installation. On both sides of the electrolytic cell body 1 in the length direction, there is a horizontally arranged positioning waist plate 4 each. The positioning waist plate 4 is located in the middle of the electrolytic cell body 1 and is arranged along the length direction of the electrolytic cell body 1. Along the length direction of the positioning waist plate 4, there are multiple diaphragm frame slots 5 corresponding to the diaphragm frame sockets 302 one by one. The middle part of the diaphragm frame can be clamped into the diaphragm frame slot for positioning. Below the positioning waist plate 4, there is a horizontally arranged diaphragm frame leg slot 6 along the length direction of the electrolytic cell body 1. The diaphragm frame leg can be placed into the diaphragm frame leg slot 6. Through the diaphragm frame leg slot 6, the bottoms of all diaphragm frames can be leveled (i.e., located in the same horizontal plane). Above the positioning plate 2, there are two limit blocks 7. The limit blocks 7 are fixed to the inner wall of the electrolytic cell body 1. The distance between the two limit blocks 7 is greater than the size of the cathode chamber diaphragm bag mouth. The two limit blocks 6 are in the same horizontal plane. A pressure rod 8 is arranged along the length direction of the positioning plate between the positioning plate 4 and the limit block 6. The pressure rod 8 can apply a downward pressure on the diaphragm frame and the rod, so that the diaphragm frame and the rod are firmly fixed and stable in the electrolytic cell body 1.

[0018] In addition, on both sides of the electrolytic cell body 1 in the length direction, there is an insulating plate 9 each. The insulating plate 9 is located at the top of the electrolytic cell body 1 and is arranged along the length direction of the electrolytic cell body 1. Along the length direction of the insulating plate 9, there are multiple anode positioning slots 10 and cathode positioning slots 11 on the insulating plate 9. Both the anode positioning slot 10 and the cathode positioning slot 11 are arc-shaped, and the diameter of the anode positioning slot 10 is adapted to the diameter of the anode rod, and the diameter of the cathode positioning slot 11 is adapted to the diameter of the cathode rod, so that the line contact between the anode and cathode rods is changed to surface contact, which is more stable. When in use, the two ends of the anode rod can be respectively placed into the anode positioning slots 10, and the two ends of the cathode rod can be respectively placed into the cathode positioning slots 11.

[0019] The usage method of the present utility model is as follows:

[0020] First, place the diaphragm frame into the electrolytic cell body 1. Specifically, when placing it, insert the two sides of the diaphragm frame into the diaphragm frame sockets 302 on the positioning plate 2 and the diaphragm frame clamping grooves 5 on the positioning waist plate 4 respectively. At the same time, insert the diaphragm frame legs into the diaphragm frame leg clamping grooves 6 at the lower part of the electrolytic cell body 1 to support the diaphragm frame legs and ensure that the diaphragm frame legs are flush. Then, install the through rod, making both ends of the through rod inserted into the through rod clamping grooves 301 respectively. After the installation is completed, place the pressure rod 8 at the position between the positioning plate 4 and the limit block 6. Finally, install the anode rod and the cathode rod. When installing, just insert both ends of the anode rod into the anode positioning grooves 10 respectively, and insert both ends of the cathode rod into the cathode positioning grooves 11 respectively.

[0021] With this electrolytic cell, the diaphragm frame can be firmly installed and fixed, and at the same time, ensure that the distance between the diaphragm frames meets the requirements.
