Description

Technical Field

[0001] This utility model relates to the field of electrolyte circulation technology for electrolytic cells, and more specifically, to an adjustable flow rate electrolyte circulation machine for electrolytic cells. Background Technology

[0002] An electrolytic cell is a device that converts electrical energy into chemical energy. It uses an external direct current to trigger redox reactions in the electrolyte, solution, or molten electrolyte, thereby achieving the conversion and separation of substances. The electrolyte circulation method refers to the method and form in which the electrolyte continuously flows through the electrolytic cell at a specific flow rate during the electrolysis process. Its core function is to maintain the uniformity of composition and temperature within the cell and to optimize electrolysis efficiency through operations such as replenishing electrolytes and treating impurities outside the cell.

[0003] The shortcomings of existing technology are as follows: In existing electrolytic cell equipment, the flow direction of the electrolyte in the pipeline is controlled by the valve body. The flow rate is controlled by rotating the valve disc at the bottom of the valve stem. However, the flow rate increases exponentially from the closed to the fully open position of the valve disc without clear gradation. This makes it impossible to pre-control the electrolyte flow rate. If the electrolyte flow rate is greater than the preset value, flooding or bubble accumulation will occur, leading to overflow. If the electrolyte flow rate is less than the preset value, polarization of the electrode surface concentration will occur, leading to underflow. This can easily cause flow fluctuations, affecting the stability of the reaction, reducing the practicality of the equipment, and hindering actual application and operation. Utility Model Content

One end of the lever 521 passes through the first outer slot 524 and the first middle slot 523 in sequence and extends into the inside of the first inner slot 522.

[0023] In practical application, according to the required size of the flow port inside the simplified valve cavity 51, the area of ​​the corresponding valve disc is changed. The lever 517 is manually moved in the slide groove 516 at the top of the control box 514. S1: When it is necessary to pre-rotate the inner circular valve disc 511, the slide plate 515 is driven to slide in the control box 514. The connecting plates 518 on both sides of the lever 517 are inserted into the slots 520 of the first vertical column, which drives the slide plate 515 in the control box 514 to move synchronously. This causes one end of the two locking rods 521 to retract from the first inner locking groove 522 into the first middle locking groove 523, releasing the inner valve rod 51. S1: Limiting the position to 0, then manually rotating the inner valve stem 510, causing the inner circular valve disc 511 to rotate inside the middle annular valve disc 57, selecting the electrolyte flow channel with a relatively small area; S2: When it is necessary to pre-rotate the valve disc composed of the inner circular valve disc 511 and the middle annular valve disc 57, drive the slide plate 515 to continue sliding in the control box 514, insert the connecting plates 518 on both sides of the lever 517 into the second vertical slot 520, drive the slide plate 515 in the control box 514 to continue to move synchronously, and drive one end of the two locking rods 521 to retract from the first middle locking slot 523 to the first outer locking slot 523. Within 24, release the limiting restrictions of the inner valve stem 510 and the middle valve tube 56, and then manually rotate the inner valve stem 510 and the middle valve tube 56 to drive the valve disc composed of the inner circular valve disc 511 and the middle annular valve disc 57 to rotate inside the outer annular valve disc 53, selecting the electrolyte flow channel port with a relatively medium area; S3: When it is necessary to pre-rotate the valve disc composed of the inner circular valve disc 511, the middle annular valve disc 57 and the outer annular valve disc 53, drive the slide plate 515 to continue sliding in the control box 514, insert the connecting plates 518 on both sides of the lever 517 into the slot 520 of the third vertical column, and drive the control box 514 to continue sliding. The slide plate 515 continues to move synchronously, causing one end of the two locking rods 521 to retract from the first outer locking groove 524 to the outside of the outer valve tube 52, releasing the limiting restrictions of the inner valve rod 510, the middle valve tube 56, and the outer valve tube 52. Then, the inner valve rod 510, the middle valve tube 56, and the outer valve tube 52 are manually rotated, causing the valve disc composed of the inner circular valve disc 511, the middle annular valve disc 57, and the outer annular valve disc 53 to rotate inside the simple valve cavity 51, selecting the electrolyte flow channel with a relatively large area. In summary, the area of ​​the preset flow port on the three-stage adjustment valve disc is realized, further realizing the operation of controlling the flow rate of the electrolyte.

[0024] This embodiment, by setting the flow regulating component 5, facilitates three-level control of the area of ​​the preset flow port on the valve disc. This allows the required flow rate of the electrolyte to be directly selected from the corresponding flow port, solving the problem of the traditional valve body driving the valve disc to rotate without graded steps, which causes the electrolyte flow rate to be higher or lower than the preset value, resulting in flooding or bubble accumulation causing overcurrent or electrode surface concentration polarization causing undercurrent. This reduces flow fluctuations, improves reaction stability, and further enhances the practicality of the equipment, which is beneficial for actual application and operation.

[0025] In one embodiment, the outer annular valve disc 53, the middle annular valve disc 57, and the inner circular valve disc 511 can be made of stainless steel. Monel alloy Ni-Cu alloy can be used as the sealing material. Combined with the stainless steel valve body, it achieves a combination of soft and hard sealing, and has the characteristics of high strength and strong corrosion resistance, making it suitable for long-term immersion in electrolyte.

[0027] In practical application, when the electrolyte in the first connecting pipe 35 flows into the auxiliary tank 42 on the second fixed plate 41, the particulate impurities in the electrolyte are filtered twice by the two filter plates 45 of different materials in the auxiliary tank 42.

[0028] This embodiment uses a purification component 4 to facilitate dual filtration of particulate impurities in the electrolyte, thereby improving the purity of the electrolyte.

[0031] In practical application of this embodiment, S1: If only the inner valve stem 510 needs to be rotated, the inner valve stem 510 is rotated directly, causing the inner circular valve disc 511 at the bottom of the inner valve stem 510 to rotate within the middle annular valve disc 57; S2: First, the second middle retaining groove 62 is passed through the interior of the second middle retaining groove 62 and extended into the second inner retaining groove 61, so that the middle valve tube 56 and the inner valve stem 510 rotate synchronously and in the same direction, causing the middle annular valve disc 57 and the inner circular valve disc 511 to rotate simultaneously in the outer annular region. S3: First, the second middle slot 62 passes through the second outer slot 63 and the interior of the second middle slot 62 in sequence and extends into the second inner slot 61, so that the outer valve tube 52, the middle valve tube 56 and the inner valve rod 510 rotate synchronously in the same direction, driving the outer annular valve disc 53, the middle annular valve disc 57 and the inner circular valve disc 511 to rotate simultaneously in the channel opening of the simple valve cavity 51, opening the flow port of the corresponding area size, and controlling the flow rate of the electrolyte.

[0032] In this embodiment, by setting a synchronization component 6, it is convenient to limit and synchronize the rotation of the valve stem at the top of the valve disc, thereby improving the stability of combining two or three valve discs of different areas into a valve disc of the required area, and further improving the stability of the subsequent flow regulating component 5.

Positioning blocks 22 are fixedly installed on the top of both sides of the anode plate 12, cathode plate 13 and diaphragm 14 respectively, and the positioning blocks 22 and positioning double plates 21 are interlocked with each other.

[0038] In practical application, when the anode plate 12, cathode plate 13, or diaphragm 14 is damaged, one of them can be lifted upwards to remove the positioning blocks 22 on both sides from the corresponding positioning double plates 21 at the top of the pool body 11, thus achieving the disassembly operation.
