Description

Technical Field

[0001] The utility model relates to the technical field of adsorption platform mechanisms, and particularly relates to a rotating adsorption platform mechanism for a PPS diaphragm cloth of an electrolytic cell. Background Technique

[0002] In the process of metal electrolytic refining, a PPS diaphragm is required to separate the anode and cathode regions, thereby controlling the ion migration and attachment deposition in the electrolyte. As one of the key components of the electrolytic cell, the main function of the PPS diaphragm is to prevent the mixing of hydrogen and oxygen and provide good ionic conductivity.

[0003] Publication No. CN218539849U discloses a rotating adsorption platform mechanism for a PPS diaphragm cloth of an electrolytic cell, which includes a box body, a rotating mechanism and an adsorption mechanism. The rotating mechanism and the adsorption mechanism are both arranged on the top of the box body. The adsorption mechanism includes a U-shaped frame, a communicating pipe, an annular disc, a flange disc and a suction cup.

[0004] The above device evacuates the air in the communicating pipe through a vacuum pump to form a vacuum state, so as to adsorb the PPS diaphragm cloth in the electrolytic cell. Inevitably, a small amount of electrolyte will be sucked into the communicating pipe during the adsorption process, and the electrolyte sucked into the communicating pipe is likely to enter the vacuum pump, causing corrosion inside the vacuum pump and reducing the service life of the adsorption platform. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a rotating adsorption platform mechanism for a PPS diaphragm cloth of an electrolytic cell, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A rotating adsorption platform mechanism for a PPS diaphragm cloth of an electrolytic cell includes an operating platform. An installation plate is fixedly installed at the bottom of the operating platform. A communicating pipe is arranged on the installation plate. A flange disc is connected to the communicating pipe. A blocking mechanism is arranged inside the communicating pipe. The blocking mechanism includes a positioning bracket fixedly installed inside the communicating pipe. A telescopic guide rod is movably installed on the positioning bracket. A blocking piston is fixedly installed at the upper end of the telescopic guide rod. A spring seat is fixedly installed at the lower end of the telescopic guide rod. A return spring is sleeved on the telescopic guide rod. A limiting mechanism is installed on one side of the positioning bracket. The limiting mechanism includes a mechanism housing fixedly installed on the positioning bracket. An electromagnet is fixedly installed at one end of the mechanism housing. A compression spring is arranged inside the mechanism housing. A limiting pin is movably installed on the mechanism housing. An armature is fixedly installed at one end of the limiting pin. The electromagnet will adsorb the armature, causing the armature to drive the limiting pin to move to one side.

[0008] Furthermore, a limiting hole is provided at the upper edge of the telescopic guide rod, and an access through hole is provided on the side wall of the positioning bracket.

[0009] Furthermore, a docking hole is provided at the bottom of the barrier piston. The upper end of the telescopic guide rod is connected to the bottom of the barrier piston through the docking hole. The telescopic guide rod is movably installed in the communication pipe through the positioning bracket. The barrier piston is movably installed in the communication pipe through the telescopic guide rod. The telescopic guide rod can move up and down following the barrier piston.

[0010] Furthermore, one end of the return spring is fixedly connected to the spring seat, and the other end of the return spring is fixedly connected to the positioning bracket. The return spring provides an upward elastic force to the positioning bracket.

[0011] Furthermore, the limiting mechanism further includes a docking base fixedly installed on the mechanism housing. A docking through hole is provided on the docking base. A hole is provided at the end of the mechanism housing, and the hole at the end of the mechanism housing is aligned with the access through hole.

[0012] Furthermore, a bolt is provided in the docking through hole, and the docking through hole is fixed to the positioning bracket through the bolt.

[0013] Furthermore, the limiting pin extends into the positioning bracket through the access through hole, and the limiting pin is embedded in the telescopic guide rod through the limiting hole. One end of the compression spring is connected to the armature, and the other end of the compression spring is connected to one end of the mechanism housing. The compression spring provides an elastic force to the armature, causing the armature to have a tendency to move forward.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] A vacuum pump is connected to the communication pipe. Through the vacuum pump, the air in the lower half of the communication pipe can be evacuated, causing the barrier piston to move downward. When the barrier piston moves downward, the air pressure in the upper half of the communication pipe will decrease, adsorbing the PPS diaphragm cloth in the electrolytic cell. And a small amount of electrolyte sucked into the communication pipe will be blocked by the barrier piston, preventing the electrolyte from being sucked into the vacuum pump and reducing the probability of corrosion of the vacuum pump, thereby extending the service life of the attachment platform.

[0016] When the barrier piston moves to the lowermost end, the compression spring will push the limiting pin to be embedded in the limiting hole on the telescopic guide rod, fixing the barrier piston and keeping the PPS diaphragm cloth in an adsorbed state. Secondly, the electromagnet can adsorb the armature. After the electromagnet adsorbs the armature, the armature will pull the limiting pin out of the limiting hole. After the limiting pin is pulled out of the limiting hole, the return spring can push the barrier piston to reset, thereby releasing the PPS diaphragm cloth. Description of the Drawings

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 Figure 2 shown, an electrolytic cell PPS diaphragm cloth rotating adsorption platform mechanism includes an operating table 1, a mounting plate 2 is fixedly installed at the bottom of the operating table 1, a connecting pipe 3 is provided on the mounting plate 2, a flange 4 is connected to the connecting pipe 3, a barrier mechanism 5 is provided in the connecting pipe 3, the barrier mechanism 5 includes a positioning bracket 504 fixedly installed in the connecting pipe 3, a telescopic guide rod 501 is movably installed on the positioning bracket 504, a barrier piston 502 is fixedly installed at the upper end of the telescopic guide rod 501, a spring seat 505 is fixedly installed at the lower end of the telescopic guide rod 501, a return spring 506 is sleeved on the telescopic guide rod 501, a limit mechanism 6 is installed on one side of the positioning bracket 504, the air in the lower half of the connecting pipe 3 can be pumped out by a vacuum pump, so that the barrier piston 502 moves downward, a negative pressure is formed in the upper half of the connecting pipe 3, the PPS diaphragm cloth is adsorbed, and the barrier piston 502 on the barrier mechanism 5 can prevent the electrolyte from being sucked into the vacuum pump during the adsorption process, reducing the probability of corrosion of the vacuum pump.

[0024] As Figure 3As shown in the figure, the blocking mechanism 5 includes a positioning bracket 504 fixedly installed in the connecting pipe 3. A telescopic guide rod 501 is movably installed on the positioning bracket 504. A blocking piston 502 is fixedly installed at the upper end of the telescopic guide rod 501. A spring seat 505 is fixedly installed at the lower end of the telescopic guide rod 501. A return spring 506 is sleeved on the telescopic guide rod 501. A limiting hole 503 is opened at the edge of the upper end of the telescopic guide rod 501. An inlet and outlet through hole 507 is opened on the side wall of the positioning bracket 504.

[0025] Specifically, a vacuum pump is connected to the connecting pipe 3. The air in the lower half of the connecting pipe 3 can be evacuated through the vacuum pump, so that the blocking piston 502 moves downward. When the blocking piston 502 moves downward, the air pressure in the upper half of the connecting pipe 3 will decrease, adsorbing the PPS diaphragm cloth in the electrolytic cell. And a small amount of electrolyte sucked into the connecting pipe 3 will be blocked by the blocking piston 502, preventing the electrolyte from being sucked into the vacuum pump and reducing the probability of the vacuum pump being corroded, thus prolonging the service life of the attachment platform.

[0026] As Figure 3 shown in the figure, the limiting mechanism 6 includes a mechanism housing 604 fixedly installed on the positioning bracket 504. An electromagnet 602 is fixedly installed at one end of the mechanism housing 604. A compression spring 601 is arranged inside the mechanism housing 604. A limiting pin 607 is movably installed on the mechanism housing 604. An armature 603 is fixedly installed at one end of the limiting pin 607. The limiting mechanism 6 further includes a docking base 605 fixedly installed on the mechanism housing 604. A docking through hole 606 is opened on the docking base 605.

[0027] Specifically, when the blocking piston 502 moves to the lowermost end, the compression spring 601 will push the limiting pin 607 to embed into the limiting hole 503 on the telescopic guide rod 501, fixing the blocking piston 502 and keeping the PPS diaphragm cloth in the adsorbed state. Secondly, the electromagnet 602 can adsorb the armature 603. After the electromagnet 602 adsorbs the armature 603, the armature 603 will pull the limiting pin 607 out of the limiting hole 503. After the limiting pin 607 disengages from the limiting hole 503, the return spring 506 can push the blocking piston 502 to reset, thus releasing the PPS diaphragm cloth.

[0028] It should be noted that the present utility model is a rotating adsorption platform mechanism for an electrolytic cell PPS diaphragm cloth. During actual use, first, the air in the lower half of the connecting pipe 3 is pumped out by a vacuum pump, causing the blocking piston 502 to move downward. When the blocking piston 502 moves downward, the air pressure in the upper half of the connecting pipe 3 will decrease, adsorbing the PPS diaphragm cloth in the electrolytic cell. During the adsorption process, the electrolyte will be blocked by the blocking piston 502 to prevent the electrolyte from entering the vacuum pump. Since the limit pin 607 is inserted into the telescopic guide rod 501 through the limit hole 503, one end of the compression spring 601 is connected to the armature block 603, and the other end of the compression spring 601 is connected to one end of the mechanism housing 604. Therefore, when the blocking piston 502 moves to the lowest position, the compression spring 601 will push the limit pin 607 into the limit hole 503 on the telescopic guide rod 501 to limit the blocking piston 502 and keep the PPS diaphragm cloth in the adsorbed state. And the user can activate the electromagnet 602. After activating the electromagnet 602, it will adsorb the armature block 603. After the electromagnet 602 adsorbs the armature block 603, the armature block 603 will pull the limit pin 607 out of the limit hole 503. Since one end of the return spring 506 is fixedly connected to the spring seat 505 and the other end of the return spring 506 is fixedly connected to the positioning bracket 504, after the limit pin 607 is pulled out of the limit hole 503, the telescopic guide rod 501 will lose its block. After the telescopic guide rod 501 loses its block, the return spring 506 will push the blocking piston 502 upward to release the PPS diaphragm cloth.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
