Description

Elastic support piece and electrolytic cell with same

This application is a divisional application of the patent application with application number 202110913284.3 entitled "resilient support, electrolytic cell, manufacturing apparatus and manufacturing method".

Technical Field

The invention relates to the field of electrolytic cells, in particular to an elastic support member and an electrolytic cell with the same.

Background

An electrolysis cell common in the industry typically comprises an anode compartment and a cathode compartment. An anode structure is arranged in the anode chamber, a cathode structure is arranged in the cathode chamber, and the anode structure and the cathode structure are respectively positioned on two sides of the ion exchange membrane and form a certain polar distance. In the ionic membrane electrolytic cell, an ionic membrane is also arranged between the cathode structure and the anode structure.

The size of the electrode distance (pole pitch) between the anode structure and the cathode structure in the electrolytic cell has a large influence on the voltage of the electrolytic cell. By reducing the pole pitch, the voltage of the electrolytic bath can be reduced, thereby reducing the consumption of electric energy. Under some circumstances, the cathode structure in the electrolytic cell is non-rigidly connected with the cell body of the electrolytic cell, and the cathode structure can be arranged in the cell body of the electrolytic cell through the elastic supporting piece, so that the arrangement is favorable for adjusting the polar distance, and the damage to the rigid touch of the ionic membrane possibly caused by the cathode structure is avoided.

However, the known elastic supports have some drawbacks, such as: the elastic force application part is not uniformly contacted with the cathode structure, so that the reduction of the voltage of the electrolytic cell is not facilitated, the uniform support cannot be realized, and the damage of an ionic membrane and the like caused by the fluctuation of the electrolyte can be caused; the lack of support between adjacent force application portions of the resilient support typically results in a difference in stiffness at that location relative to other locations, thereby again compromising uniform contact of the resilient support with the cathode structure.

It is therefore desirable to provide an elastic support and an electrolytic cell having the same that at least partially address the above problems.

What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.

The invention provides an elastic support for an electrolytic cell, the electrolytic cell with the elastic support, and a manufacturing device and a manufacturing method for manufacturing the elastic support. The electrolytic cell is provided with a cathode part and an anode part in the cell body, wherein the cathode part is configured as a cathode net, for example, and the anode part is configured as an anode net, for example. The elastic support is mounted in the cell body and is positioned at a side of the cathode part facing away from the anode part and serves to support the cathode part.

Fig. 1-7 show some preferred embodiments according to the invention in respect of an elastic support. It should be noted that the directions, positions, etc. mentioned in the description of the present invention can be understood by referring to the specific embodiments shown in fig. 1 to 7, and the respective directions, positions, etc. should be understood as relative directions, relative positions, not absolute directions, absolute positions, between the respective components.

Referring first to fig. 1 to 2, the elastic support 100 includes a base plate 10, the base plate 10 having a flat plate structure and a cathode member spaced apart therefrom, and a plurality of elastic region portions 20 punched at predetermined positions of the base plate 10. Referring to fig. 1, each elastic region part 20 includes an elastic piece punch 23, a first row 21 and a second row 22, the contour lines of the elastic piece punch holes 23 are closed on the base plate 10, and the contour lines include a first contour line 201 and a second contour line 202 parallel to each other. Each of the first row of elastic pieces 21 extends from the first contour 201 towards the cathode part and towards the second contour 202, each of the second row of elastic pieces 22 extends from the second contour 202 of the substrate 10 towards the cathode part and towards the first contour 201, and the elastic pieces in the first row of elastic pieces 21 and the elastic pieces in the second row of elastic pieces 22 are arranged alternately.

It is understood that the first row of elastic sheets 21 and the second row of elastic sheets 22 are part of the plate material forming the base plate 10 before being processed, and the elastic sheets are processed by a blanking process in a stamping process, and the original positions of the elastic sheets form the elastic sheet stamping holes 23; and then bending the elastic sheet to form by a bending process in a stamping process.

A pair of adjacent elastic region portions 20, a first elastic region portion 20a and a second elastic region portion 20b, in the transverse direction D1 is shown in perspective view in fig. 2, and it can be understood with reference to fig. 2 that all the elastic sheets in the first and second rows of elastic sheets 21 and 22 are in elastic contact with the cathode assembly to provide uniform elastic support to the cathode assembly. Further, the base plate 10 is parallel to the surface of the cathode member facing the base plate 10, and each of the elastic pieces elastically supports the surface of the cathode member.

With continued reference to fig. 1 and 2, in the present embodiment, the base plate 10 is substantially rectangular, and the elastic piece punched hole 23 is also substantially rectangular. The base plate 10 and the elastic piece punched hole 23 are aligned in the lateral and longitudinal directions, each having a pair of edges (i.e., the width of the rectangle) extending in the lateral direction D1 and a pair of edges (i.e., the length of the rectangle) extending in the longitudinal direction D2, and the first contour 201 and the second contour 202 defining the elastic piece punched hole 23 are the edges of the elastic piece punched hole 23 extending in the longitudinal direction D2. Preferably, the plurality of elastic region parts 20 are arranged in a matrix on the substrate 10 in the longitudinal direction D2 and the transverse direction D1, and the intermediate supporting legs 30 are plural and respectively disposed between the elastic region parts 20 adjacent to each other in the transverse direction D1 of the substrate 10.

For convenience of description, a direction perpendicular to the substrate 10 is referred to as a height direction D3, and the height direction D3, the lateral direction D1, and the longitudinal direction D2 are orthogonal in a three-dimensional coordinate system.

The specific structure of the elastic sheet on the elastic support 100 is shown in fig. 2 and 3. Referring to fig. 2 and 3, the elastic pieces in the first row of elastic pieces 21 and the elastic pieces in the second row of elastic pieces 22 are identical in structure and shape, each of the first row of elastic pieces 21 includes a straight wall section 221 connected to the base plate 10 and an arc-shaped section 222 bent from an end of the straight wall section 221, and the arc-shaped section 222 is used for elastically contacting the cathode member; each of the second row elastic pieces 22 includes a straight wall section 212 connected to the base plate 10 and an arc-shaped section 211 bent from an end of the straight wall section 212, the arc-shaped section 211 for elastically contacting the cathode assembly. The first row of elastic blades 21 and the second row of elastic blades 22, each formed in a strip shape extending in the transverse direction D1 and towards the anode assembly of the electrolyzer, are arranged opposite to each other, the first row of elastic blades 21 and the second row of elastic blades 22 together forming a comb-like structure, the first row of elastic blades 21 and the second row of elastic blades 22 being crossed with each other in a front view as shown in fig. 3, forming an X-shape. That is, on a projection plane perpendicular to the longitudinal direction D2, a projection of the first row of elastic pieces 21 and a projection of the second row of elastic pieces 22 intersect in an X shape.

Preferably, for each elastic region part 20, a gap exists between adjacent two elastic sheets in the longitudinal direction D2 of the elastic sheet punched hole 23. When the elastic sheet is processed on the plate material constituting the base plate 10, the gap may be first punched out using a punching die in a punching apparatus, and then the elastic sheet may be bent and formed using a bending die in the punching apparatus. More preferably, before bending, the elastic sheet may be thinned and widened to make the thickness of the elastic sheet smaller than that of the substrate 10, and such elastic sheet is formed into a soft strip shape, which is more flexible and has better elasticity.

With continued reference to fig. 3, the resilient support 100 further includes a stamped middle support foot 30 and an edge support foot 40. The intermediate support leg 30 is formed on the side of the base plate 10 facing away from the cathode element and between two adjacent elastic zone portions 20, the intermediate support leg 30 being fixedly connected between the base plate 10 and the bottom wall of the tank. Since the intermediate support legs 30 are formed by punching a predetermined position of the substrate 10, the substrate 10 is also simultaneously formed with the support leg punching holes 12 adjacent to the intermediate support legs 30.

The edge supporting leg 40 is formed by bending from the edge of the base plate 10 toward the bottom wall of the tank body. The edge support feet 40 are used to engage with the ribs within the tank. Specifically, referring to fig. 5, a plurality of elastic supporting members 100 can be co-located in the same electrolytic cell, a rib plate 401 extending toward the base plate 10 is disposed on a bottom wall 400 of the electrolytic cell body, and the rib plate 401 can be fastened to the inner side of the edge supporting leg 40 to further fix the elastic supporting members 100 relative to the electrolytic cell body. Referring to fig. 3 and 5, the dimension of the edge support foot 40 in the height direction D3 is smaller than the dimension of the middle support foot 30 in the height direction D3.

In the present embodiment, since the contour line of the elastic piece punching hole 23 is closed on the substrate 10, the elastic piece punching hole 23 does not extend from the substrate 10 to the edge supporting leg 40 or the middle supporting leg 30 other than the substrate 10. Such an arrangement enables the elastic support 100 to avoid a reduction in rigidity and stability due to the punched hole, and also avoid deformation during use.

Turning back to fig. 1. Preferably, two longitudinal edges (which will be referred to as a first longitudinal edge and a second longitudinal edge) of the base plate 10 extending in the longitudinal direction D1 thereof are each provided with a plurality of edge support feet 40, and on each longitudinal edge, there is a notch portion 41 recessed inward in the extending direction of the base plate 10 between the adjacent edge support feet 40. The edge support foot 40 at the first longitudinal edge and the edge support foot 40 at the second longitudinal edge are offset from each other in the transverse direction D1 of the base plate 10 such that in the transverse direction D1: the edge support foot 40 on the first longitudinal edge and the notch 41 on the second longitudinal edge are aligned; the notch 41 on the first longitudinal edge is aligned with the edge support foot 40 on the second longitudinal edge.

Such arrangement of the edge supporting foot 40 and the notch portion 41 facilitates the engagement between at least two elastic supports 100 with each other. As already mentioned in the foregoing, for example with reference to fig. 5, at least two elastic supports 100 can be used jointly within the same electrolytic cell. A plan view of a combined state of two adjacent elastic supports 100 is shown in fig. 4, and in fig. 4, at least two pieces of the elastic supports 100 are arranged in the transverse direction D1 of the base plate 10 such that the edge supporting legs 40 and the notched portions 41 of the adjacent elastic supports 100 are fitted to each other in a projection plane parallel to the base plate 10. Such an arrangement allows for a tighter arrangement of adjacent resilient supports 100, more fully utilizing the limited space within the cell body to provide a greater area of resilient support for the cathode assembly.

In this embodiment, the elastic region is formed by punching, and the elastic piece hole is an elastic piece punching hole. In other embodiments, not shown, however, the elastic region portion may be formed by other processes.

In addition, in other embodiments not shown, the elastic sheet may have other various arrangements. For example, instead of "the first row and the second row are alternately arranged", the first row and the second row may be arranged in alignment one by one in the transverse direction D1, in which case projections of the first row and the second row may together form a ". Shape" on a projection plane perpendicular to the longitudinal direction D2.

The preferred embodiment of the present invention also provides an electrolytic cell comprising the elastic support member 100 shown in fig. 1 to 5. As mentioned before, the cell further comprises a cathode part, e.g. a cathode mesh, an anode part, e.g. an anode mesh, the resilient support 100 being adapted to support the cathode part.

The electrolytic cell in the present embodiment may be an ion membrane electrolytic cell, and an electrolytic cell located between the cathode member and the anode member may be provided in the electrolytic cell.

The present invention also provides a production apparatus and a production method for manufacturing the elastic support 100 shown in fig. 1 to 5, for example. The production equipment comprises a stamping die for processing the sheet material, wherein the stamping die comprises a first stamping die series for processing the elastic sheet on the sheet material, a second stamping die series for processing the middle supporting leg on the sheet material and an edge supporting leg stamping die for bending a part of the edge of the sheet material to form an edge supporting leg.

Each stamping die in the first series of stamping dies forms a continuously stamping progressive die in the sequence described above.

The second punching die includes: a middle support leg stamping die for stamping the shape profile of the middle support leg on the sheet material, the stamping die is a blanking die for example; and the middle supporting leg bending stamping die is used for bending and shaping the middle supporting leg relative to the main body of the plate material, and the stamping die is a bending die for example. The stamping progressive die for continuously stamping is formed by each stamping die in the stamping die series for processing the middle supporting leg on the plate according to the sequence.

Preferably, the manufacturing apparatus further includes a measurement calibration device 300 for measuring and calibrating the protrusion height of the elastic sheet after the completion of the process, and the measurement calibration device 300 includes a positioning base 311, a distance measuring device 309, a calibration device, and a control module. Wherein the positioning base 311 is configured to fixedly support the base plate 10 of the elastic support 100; the distance measuring device 309 is configured to obtain a distance value in the height direction D3 between the end (i.e., the top end of the arc-shaped segment of the elastic piece in fig. 6) of each elastic piece (e.g., the first row of elastic pieces 21 and the second row of elastic pieces 22) away from the substrate 10 and a reference plane, which is a plane on which the substrate 10 is located or is parallel to the substrate 10; the calibration device is configured to provide a force perpendicular to the reference plane, i.e., a force in the height direction D3, to the elastic sheet; the control module is configured to communicate with the ranging device 309, the calibration device.

The control module can be integrated in a PLC control system or an MCU monolithic control system, and further configured to: receiving a signal containing the range value from ranging device 309; judging whether the distance value is within a pre-stored threshold range; if the judgment result is negative, controlling the calibration device to provide corresponding acting force to the elastic sheet so as to adjust the height of the elastic sheet relative to the substrate 10, thereby calibrating the distance value between the elastic sheet and the reference surface; the ranging means 309 and the calibration means are controlled to repeat the above ranging, determining and calibrating steps until the obtained range value falls within the threshold range.

Specifically, in the present embodiment, the calibration device further includes a top frame 301 and a bottom frame 302, wherein the positioning base 311 is configured as a straight wall protruding from the bottom frame 302 toward the top frame 301, so that the elastic support 100 can be supported by the straight wall in a suspended manner. The elastic support member 100 is fixed to the bottom frame 302 by bolts 310 penetrating the elastic piece punching holes 23 and the support leg punching holes 12, respectively.

A distance measuring device 309, such as an infrared distance measuring device or an ultrasonic distance measuring device, is disposed on top frame 301 and faces bottom frame 302. In such an embodiment, the reference plane is substantially the plane in which the emitter head of the ranging device 309 is located, and may be substantially the bottom surface of the top frame 301, for example. In other embodiments, not shown, however, the distance measuring device may be mounted on the base frame below the arcuate segment of the flexible sheet and emit an infrared or ultrasonic signal upwardly, and in such embodiments, the reference plane may be, for example, the plane of the base plate or may be the top surface of the base frame.

The calibration device includes a top power ram 303 and a bottom power ram 304. A top power push rod 303 extends from the top frame 301 toward the elastic sheet to directly or indirectly apply a force to the elastic sheet. A bottom electric push rod 304 extends from the bottom frame 302 toward the elastic sheet to directly or indirectly apply force to the elastic sheet. In the present embodiment, the top electric ram 303 and the bottom electric ram 304 indirectly urge the elastic pieces via the air bags, but in other embodiments not shown, the respective ends of the top electric ram 303 and the bottom electric ram 304 may directly act on the elastic pieces.

Returning to the present embodiment, the tip of the top electric putter 303 is provided with a top air bag 305, and the top air bag 305 abuts against the top surface of the elastic sheet to directly apply force to the elastic sheet; the end of the bottom power pushrod 304 is provided with a bottom air bag 306, and the bottom air bag 306 abuts against the bottom surface of the elastic sheet to directly apply force to the elastic sheet. In such an embodiment, the top airbag 305 and the bottom airbag 306 are used to adjust the height of the extension of the elastic sheet, and the top electric push rod 303 and the bottom electric push rod 304 are used to adjust the position of the airbags. Specifically, the top electric putter 303 is configured to be retractable in the height direction D3 for adjusting the initial position of the top air bag 305; the bottom electric push rod 304 is configured to be able to telescope in the height direction D3 for adjusting the initial position of the bottom air bag 306; the top airbag 305 and the bottom airbag 306 are configured to be able to adjust the distance value (i.e., adjust the height at which the elastic pieces protrude) by changing the airbag pressure. To ensure accurate ranging, the top bladder 305 and the bottom bladder 306 are out of contact with the flexible sheet during the ranging step. Of course, the top electric push rod 303 and the bottom electric push rod 304 can also be directly used for adjusting the height of the elastic piece.

Preferably, the top bladder 305 and the bottom bladder 306 are disposed at the position where the elastic sheet is connected to the base plate 10, that is, the position where the calibration means applies force to the elastic sheet. According to the lever principle, it can be known that for the cantilever structure of the elastic sheet, the force arm at the position of the elastic sheet close to the substrate 10 is smaller, so that the force applied at the position is not easy to cause the elastic sheet to be greatly raised or greatly reduced, and the accurate adjustment of the height of the elastic sheet is facilitated.

It is also preferred that the top bladder 305 and the bottom bladder 306 acting on the same elastic sheet are slightly offset in the transverse direction D1, such an arrangement avoiding the top bladder 305 and the bottom bladder 306 interfering with each other, to promote flexibility and effectiveness of adjustment.

Further, the apparatus comprises an ultrasonic generator 308 connected to the top balloon 305 and the bottom balloon 306 via an ultrasonic vibrator 307, the ultrasonic generator 308 being configured to perform vibration correction of the elastomeric strip via the top balloon 305 and the bottom balloon 306. The top air bag 305 and the bottom air bag 306 are respectively connected with a compressed air source through pneumatic pipelines, an electric air release valve, an electric stop valve and an electric pressure regulating valve are sequentially arranged on the pneumatic pipelines from the pressurized air bag to the compressed air source, and the electric air release valve, the electric stop valve and the electric pressure regulating valve are also communicated with the control module.

The distance measuring devices 309, the top electric push rod 303, the bottom electric push rod 304, the top air bag 305, the bottom air bag 306 and the like are all multiple and are respectively arranged on the top frame 301 and the bottom frame 302 in an array mode so as to correspond to the elastic sheets one by one.

The preferred embodiment of the present invention also provides a method of manufacturing the elastic support 100 as shown in fig. 1 to 5, which can be implemented by the above-described manufacturing apparatus. Referring to fig. 7, the method comprises a processing step S1, which processing step S1 in turn comprises the following steps: selecting a plate in a flat plate form; processing an elastic sheet on a plate through a blanking die in a stamping die, thinning and widening the elastic sheet by adopting a plane punch, bending and forming the elastic sheet relative to a main body of the plate by using a bending die in the stamping die, and blanking the appearance of the elastic sheet; forming a middle supporting leg on the plate through a stamping process, and bending and forming the middle supporting leg relative to the main body of the plate; and bending the edge of the plate to form an edge supporting leg. The body of the sheet material constitutes the base plate of the elastic support. According to the invention, the complete elastic supporting piece is processed on one plate through a stamping process, the manufacturing process is efficient and convenient, and the processed elastic supporting piece has good stability.

With continued reference to fig. 7, the method further includes a detection and correction step S2 after the step S1 of machining the elastic support 100, and the detection and correction step S2 may be implemented by the detection and correction device 300 shown in fig. 6. The detection correction step S2 includes:

step S21: a value of a distance between an end of each elastic piece remote from the substrate 10 and a reference plane in a direction perpendicular to the reference plane, the reference plane being a plane on which the substrate 10 is located or a plane parallel to the substrate 10, is obtained. This step may be implemented, for example, by the ranging device 309 in fig. 6, where the ranging device 309 sends a signal containing the ranging result to the control module after ranging.

Step S22: a determination is made as to whether the distance value is within a threshold range, the determination being made in the control module.

If the judgment result is yes (Y), the manufacturing is finished; if the determination result is no (N), step S23 is entered (for example, by the measurement calibration apparatus 300 shown in fig. 6): the control module sends a control signal to the calibration device to control the calibration device to apply a force perpendicular to the substrate 10 to the elastic sheet to calibrate the distance value between the elastic sheet and the reference plane. The calibration means comprise, for example, a top electric push rod 303, a bottom electric push rod 304, a top air bag 305, a bottom air bag 306 in fig. 6.

That is, step S23 is to perform ultrasonic correction on the strip-shaped elastic piece whose height position error exceeds the threshold value, and refer to fig. 6 at the same time, specifically, the control module controls the top electric push rod 303 and the bottom electric push rod 304 to adjust the positions of the top airbag 305 and the bottom airbag 306, then the control module controls to activate the top airbag 305 and the bottom airbag 306 to respectively press and clamp the elastic piece from the top surface and the bottom surface of the root of the elastic piece, and adjusts the height of the arc-shaped section of the elastic piece by respectively adjusting the airbag pressures of the top airbag 305 and the bottom airbag 306, so that the elastic piece performs a certain reverse pre-deformation with respect to the height error direction, and then the ultrasonic generator 30818 is activated to perform vibration correction to reduce the rebound deformation amount of the elastic piece 4.

The above steps S21, S22 and S23 are repeated. Specifically, after step S23, the control module controls the top airbag 305 and the bottom airbag 306 to deflate, so that the top airbag 305 and the bottom airbag 306 are out of contact with the strip-shaped elastic sheet, and then detects the height error of the arc-shaped section of the elastic sheet again, if the height error still exceeds the height error, the reverse pre-deformation amount is adjusted by the top airbag 305 and the bottom airbag 306 again according to the height error, and then vibration correction is performed again to reduce the rebound deformation amount of the elastic sheet. And then, the above steps S21, S22 and S23 are continuously repeated until the obtained distance value falls within the threshold range.

As described above, the top airbag 305 and the bottom airbag 306 are used to adjust the height of the arc-shaped section of the elastic sheet, and the top electric push rod 303 and the bottom electric push rod 304 are used to adjust the initial positions of the top airbag 305 and the bottom airbag 306. However, if necessary, the control module can also adjust the amount of the reverse pre-deformation of the elastic sheet by synchronously adjusting the telescopic rods of the top electric push rod 303 and the bottom electric push rod 304, and maintain the proper clamping force on the strip-shaped elastic sheet by controlling the pressures of the top air bag 305 and the bottom air bag 306.

The distance measurement calibration step provided by the invention can ensure that all the elastic sheets on the elastic support part have consistent extension heights, so that the elastic force provided by all the elastic areas of the elastic support part is consistent.

The method may further comprise other steps, such as designing a stamping die before the machining starts, the designed stamping die comprising the first stamping die series, the second stamping die series, etc. as described above.

The elastic support piece provided by the invention has better strength and stability, and can provide stable and uniform elastic support for the cathode assembly in the electrolytic cell so as to integrally improve the service performance of the electrolytic cell. For example, the provision of the intermediate support foot provides the resilient support with greater stability. And because the contour line of the elastic sheet punching hole is closed on the substrate, the elastic sheet punching hole does not extend to the edge supporting leg and the middle supporting leg outside the substrate from the substrate, so that the rigidity and the stability of the elastic supporting piece can not be lost due to the punching hole, and the deformation in the use process can also be avoided.
