Description

Technical Field

[0001] The present invention relates to the technical field of anode plates, and in particular to an integrated anode capable of collecting acid mist. Background Art

[0002] When electrolyzing / electrowinning metals such as zinc, copper, nickel, cobalt, and manganese in a sulfate system, acid mist will be generated at the anode. If not collected and treated, it will be emitted into the external environment, causing harm to the external environment and human health.

[0003] For this reason, Chinese invention patent CN111690953A discloses a non-soluble frame-shaped anode structure capable of collecting acid mist, which includes a frame-shaped anode. Connecting ribs are fixed on the frame-shaped anode. A conductive screw is threadedly connected to the top of the connecting rib, and the upper end of the conductive screw is connected to a conductive beam; A gas collection hood is fixed between the connecting rib and the conductive screw. The lower edge of the gas collection hood is hermetically connected with an isolation film. The isolation film is in the shape of a pocket, and the size of the isolation film matches that of the frame-shaped anode. The frame-shaped anode is completely wrapped in the closed space formed by the gas collection hood and the isolation film. The frame-shaped anode is composed of a frame and a titanium mesh (i.e., the anode) fixed on the frame; An acid mist outlet is provided on one side of the gas collection hood, and the acid mist outlet is connected to a suction fan or a negative pressure pump, so that air can be drawn at the acid mist outlet, and the acid mist can be directly drawn out and collected from the outlet, avoiding the direct discharge of the acid mist into the environment during the electrowinning process.

[0004] This anode structure has the following defects:

[0005] 1) The gas collection hood and the frame-shaped anode are separately manufactured, which is not only inconvenient for installation and production, but also has certain deficiencies in structural strength and sealing performance.

[0006] 2) Since only the mouth part of the pocket-shaped isolation film is hermetically connected to the lower edge of the gas collection hood, the side walls on both the front and back sides of the entire isolation film are in a fluffy state. This leads to: on the one hand, the thickness dimension of the entire anode structure becomes larger, which has an adverse impact on the pole pitch of the electrolytic cell; on the other hand, the side walls on both the front and back sides of the isolation film are likely to touch the anode or cathode during use, which will not only cause a decrease in the electrolysis / electrowinning efficiency of the anode or cathode, but also damage the isolation film, thereby affecting the service life of the isolation film. At the same time, it will also cause a short circuit phenomenon between the anode and the cathode.

[0007] 3) Since the pocket-shaped isolation film is usually sewn, after a long time of use, the thread at the sewing place is easily corroded, thus affecting the integrity and filtration performance of the pocket-shaped isolation film.

[0008] 4) Affected by the working pressure in the anode chamber, the side walls on both the front and back sides of the pocket-shaped isolation film are also prone to bulge outwards, further intensifying the contact with the cathode in the electrolytic cell, and causing the short circuit phenomenon between the anode and the cathode to occur frequently.

[0009] Therefore, it is necessary for relevant practitioners to make improvements. Summary of the Invention

[0025] The beneficial effects of the present invention are as follows:

[0026] 1) The integral anode of the present invention has high structural strength, long service life, good sealing performance, is easy to install and manufacture, and is convenient to maintain. When the anode plate in the anode chamber is damaged or reaches the service life, only the two sheet-like diaphragms and related components need to be opened, and then the anode plate is separated from the anode plate bracket and replaced separately, without replacing the anode plate frame, anode plate bracket, etc., thus greatly reducing the maintenance cost.

[0027] 2) The integral anode of the present invention is designed with two sheet-like diaphragms (i.e., the first diaphragm and the second diaphragm) respectively covering the lower part of the front side and the lower part of the back side of the anode plate frame to isolate the anode chamber. In this structure, the peripheries of the two sheet-like diaphragms are respectively detachably and sealingly connected to the lower part of the front side of the anode plate frame and the lower end of the first upper sealing plate and the lower part of the back side of the anode plate frame and the lower end of the second upper sealing plate. Therefore, the peripheries of the two sheet-like diaphragms are tightened, which can ensure the flatness of the diaphragm surfaces of the two sheet-like diaphragms, avoid the phenomenon of contacting the anode plate in the anode chamber or the adjacent cathode plate in the electrolytic cell during use, and solve the problems such as the decrease in the working efficiency of the anode plate / cathode plate and the easy damage and short service life of the diaphragm caused by this contact phenomenon.

[0028] 3) Both diaphragms in the present invention are of an integral sheet-like structure without sewing thread ends, so the phenomenon of thread end corrosion as in the prior art will not occur to affect the integrity and filtration performance of the diaphragm.

[0029] 4) Outer guardrails are respectively arranged on the outer sides of the two sheet-like diaphragms of the present invention, which can effectively prevent the two sheet-like diaphragms from bulging outwards during work, and further avoid the problem of short circuit between the anode and the cathode caused by the contact between the diaphragm and the adjacent cathode plate.

[0030] 5) The thickness dimension of the integral anode of the present invention is smaller than that of the existing anode sleeve method, which can avoid adverse effects on the pole pitch of the electrolytic cell. Description of the Drawings

[0041] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0042] As Figures 1 to 10 shown, an integrated anode capable of collecting acid mist provided by the present invention includes an anode plate 1, an anode plate frame 2, an anode plate support 3, a conductive beam 4, a conductive connecting piece 5, a first upper sealing plate 6, a second upper sealing plate 7, a first diaphragm 8, and a second diaphragm 9.

[0043] The first upper sealing plate 6 is connected to the upper part of the front side of the anode plate frame 2, the second upper sealing plate 7 is connected to the upper part of the back side of the anode plate frame 2, and a gas collecting chamber 10 is formed between the first upper sealing plate 6 and the second upper sealing plate 7 and the upper part of the anode plate frame 2.

[0044] Both the first diaphragm 8 and the second diaphragm 9 are sheet-like structures. The first diaphragm 8 covers the lower part of the front side of the anode plate frame 2, and the second diaphragm 9 covers the lower part of the back side of the anode plate frame 2. Moreover, the periphery 800 of the first diaphragm 8 is detachably and sealingly connected to the lower part of the front side of the anode plate frame 2 and the lower end of the first upper sealing plate 6, and the periphery 900 of the second diaphragm 9 is detachably and sealingly connected to the lower part of the back side of the anode plate frame 2 and the lower end of the second upper sealing plate 7. An anode chamber 11 communicating with the gas collecting chamber 10 is formed between the first diaphragm 8 and the second diaphragm 9 and the lower part of the anode plate frame 2, and the anode plate 1 is placed in the anode chamber 11. Specifically, the first diaphragm 8 and the second diaphragm 9 can be made of common materials in the industry, which have many micropores for allowing the passage of electric ions, but are barrier to the electrolyte and gas.

[0045] The upper part of the anode plate support 3 extends into the gas collecting chamber 10, and the lower part of the anode plate support 3 extends into the upper end of the anode chamber 11 and is formed with an anode plate mounting portion 300. The upper end of the anode plate 1 is fixedly connected to the anode plate mounting portion 300. The conductive beam 4 is located above the anode plate frame 2. The upper end of the conductive connecting member 5 is connected to the conductive beam 4, and the lower end of the conductive connecting member 5 extends into the gas collecting chamber 10 and is connected to the upper part of the anode plate support 3. The conductive beam 4 is composed of a copper beam body 42 and a cast lead layer 41 coated on the outer surface of the copper beam body 42, so it has good electrical conductivity and corrosion resistance. The conductive connecting member 5, the anode plate support 3 and the anode plate 1 are all made of titanium or titanium alloy, and also have good electrical conductivity and corrosion resistance. When the conductive beam 4 is electrified, through the electrical conduction of the conductive connecting member 5 and the anode plate support 3, the anode plate 1 can be electrified to work.

[0046] An exhaust port 201 communicating with the gas collecting chamber 10 and / or the anode chamber 11 is provided in the upper part of the anode plate frame 2. The acid mist generated when the anode plate 1 is electrified to work will flow upward from the anode chamber 11 into the gas collecting chamber 10 and be exported outward through the exhaust port 201 to an external collecting device for cleaning. At the same time, in order to ensure that the acid mist can be smoothly exported from the exhaust port 201, an exhaust fan or a negative pressure pump can be externally connected to the exhaust port 201.

[0047] In one embodiment of the present invention, the integrated anode further includes a first gasket 12, a second gasket 13, a first pressing plate 14, and a second pressing plate 15, which are respectively in a frame shape. The first gasket 12 is placed between the inner surface of the periphery of the first diaphragm 8, the outer surface of the lower part of the front side of the anode plate frame 2, and the outer surface of the lower end of the first upper sealing plate 6. The first pressing plate 14 presses against the outer surface of the periphery of the first diaphragm 8. The second gasket 13 is placed between the inner surface of the periphery of the second diaphragm 9, the outer surface of the lower part of the reverse side of the anode plate frame 2, and the outer surface of the lower end of the second upper sealing plate 7. The second pressing plate 15 presses against the outer surface of the periphery of the second diaphragm 9. Such a structural arrangement can not only improve the sealing performance of the peripheries of the first diaphragm 8 and the second diaphragm 9, so that the gas and liquid in the anode chamber 11 will not overflow through the connection gap at the peripheries of the first diaphragm 8 and the second diaphragm 9, but also make the peripheries of the first diaphragm 8 and the second diaphragm 9 tightened, thus ensuring the flatness of the membrane surface during use.

[0048] In one embodiment of the present invention, the integrated anode further includes a plurality of fastening bolts 16 arranged at intervals along the frame contour of the first pressing plate 14 or the second pressing plate 15, and lock nuts 17 matching with the respective fastening bolts 16.

[0049] Each fastening bolt 16 sequentially passes through the second pressing plate 15, the periphery of the second diaphragm 9, the second gasket 13, the lower part of the reverse side of the anode plate frame 2 or the lower end of the second upper sealing plate 7, the lower part of the front side of the anode plate frame 2 or the lower end of the first upper sealing plate 6, the first gasket 12, the periphery of the first diaphragm 8, and the first pressing plate 14, and then is tightly connected with the corresponding lock nut 17, so as to realize the detachable sealing connection between the periphery 800 of the first diaphragm 8 and the lower part of the front side of the anode plate frame 2 and the lower end of the first upper sealing plate 6, and the detachable sealing connection between the periphery 900 of the second diaphragm 9 and the lower part of the reverse side of the anode plate frame 2 and the lower end of the second upper sealing plate 7.

[0050] Alternatively, each fastening bolt 16 sequentially passes through the first pressing plate 14, the periphery of the first diaphragm 8, the first gasket 12, the lower part of the front side of the anode plate frame 2 or the lower end of the first upper sealing plate 6, the lower part of the reverse side of the anode plate frame 2 or the lower end of the second upper sealing plate 7, the second gasket 13, the periphery of the second diaphragm 9, and the second pressing plate 15, and then is tightly connected with the corresponding lock nut 17, so as to realize the detachable sealing connection between the periphery 800 of the first diaphragm 8 and the lower part of the front side of the anode plate frame 2 and the lower end of the first upper sealing plate 6, and the detachable sealing connection between the periphery 900 of the second diaphragm 9 and the lower part of the reverse side of the anode plate frame 2 and the lower end of the second upper sealing plate 7.

[0051] In this structure, since the peripheral edge 800 of the first diaphragm 8 and the peripheral edge 900 of the second diaphragm 9 are respectively pressed by the first pressing plate 14 and the second pressing plate 15, and the fastening bolts 16 are arranged at intervals according to the frame-shaped contour of the first pressing plate 14 or the second pressing plate 15, the peripheral edges of the first diaphragm 8 and the second diaphragm 9 are fully tightened, thereby ensuring the flatness of the two diaphragm surfaces. At the same time, the fastening bolt and the lock nut are used in combination to achieve locking, which is not only conducive to installation and disassembly, but also conducive to improving the firmness of the connection.

[0052] Moreover, connection holes for the corresponding fastening bolts 16 to penetrate are preset on the first pressing plate 14, the peripheral edge of the first diaphragm 8, the first gasket 12, the lower part of the front side of the anode plate frame 2 or the lower end of the first upper sealing plate 6, the lower part of the reverse side of the anode plate frame 2 or the lower end of the second upper sealing plate 7, the second gasket 13, the peripheral edge of the second diaphragm 9 and the second pressing plate 15.

[0053] In an embodiment of the present invention, the integrated anode further includes a first outer guardrail 18 and a second outer guardrail 19. The first outer guardrail 18 is arranged outside the first diaphragm 8 to prevent the first diaphragm 8 from bulging outwards. At the same time, the upper and lower ends of the first outer guardrail 18 respectively press against the outer surface of the first pressing plate 14, and first fixing holes 180 for the corresponding fastening bolts 16 to penetrate are respectively provided at the upper and lower ends of the first outer guardrail 18. The second outer guardrail 19 is arranged outside the second diaphragm 9 to prevent the second diaphragm 9 from bulging outwards. At the same time, the upper and lower ends of the second outer guardrail 19 respectively press against the outer surface of the second pressing plate 15, and second fixing holes 190 for the corresponding fastening bolts 16 to penetrate are respectively provided at the upper and lower ends of the second outer guardrail 19. In this structure, since the first outer guardrail 18 and the second outer guardrail 19 can respectively prevent the first diaphragm 8 and the second diaphragm 9 from bulging outwards, it can effectively ensure that the two diaphragms will not come into contact short circuit with the cathode plates adjacent to them in the electrolytic cell during use.

[0054] Further, both the first outer guardrail 18 and the second outer guardrail 19 include: two longitudinal bars 181 or 191 spaced along the width direction of the anode plate frame 2, an upper end portion 182 or 192 connected to the upper ends of the two longitudinal bars 181 or 191 and used to press against the outer surface of the upper end of the first pressing plate 14 or the second pressing plate 15, a lower end portion 183 or 193 connected to the lower ends of the two longitudinal bars 181 or 191 and used to press against the outer surface of the lower end of the first pressing plate 14 or the second pressing plate 15, and several cross bars 184 or 194 spaced along the up-down direction between the two longitudinal bars 181 or 191. Through holes 185 or 195 are formed between two adjacent cross bars 184 or 194, between the uppermost cross bar 184 or 194 and the upper end portion 182 or 192, and between the lowermost cross bar 184 or 194 and the lower end portion 183 or 193. Moreover, the first fixing holes 180 or the second fixing holes 190 are respectively provided on the upper end portion 182 or 192 and the lower end portion 183 or 193. In this structure, the arrangement of the through holes 185 or 195 can reduce the shielding area of the first outer guardrail 18 and the second outer guardrail 19 on the first diaphragm 8 and the second diaphragm 9, and further increase the passing area of the ions during operation.

[0055] Furthermore, there are two or more first outer guardrails 18 and two or more second outer guardrails 19. The two or more first outer guardrails 18 are spaced along the width direction of the anode plate frame 2 outside the first diaphragm 8, and the two or more second outer guardrails 19 are spaced along the width direction of the anode plate frame 2 outside the second diaphragm 9, so as to increase the performance of preventing the first diaphragm 8 and the second diaphragm 9 from bulging outwards.

[0056] In an embodiment of the present invention, the anode plate frame 2 includes a U-shaped frame body 2a integrally formed and opening upwards and an upper frame edge 2b connected to the open end of the U-shaped frame body 2a to close the open end. The U-shaped frame body 2a includes two side frame edges 2a1 and a bottom frame edge 2a2. The gas collection chamber 10 is formed by surrounding the first upper sealing plate 6, the second upper sealing plate 7, the upper frame edge 2b and the upper parts of the two side frame edges 2a1. A through hole 2b1 for the conductive connecting member 5 to pass through is provided on the upper frame edge 2b. The conductive connecting member 5 has a shape matching the through hole 2b1, and the conductive connecting member 5 is sealed and welded along its circumference with the through hole 2b1, so that the gas in the gas collection chamber 10 will not overflow through the gap between the conductive connecting member 5 and the through hole 2b1. At the same time, the anode chamber 11 is formed by surrounding the first diaphragm 8, the second diaphragm 9, the lower parts of the two side frame edges 2a1 and the bottom frame edge 2a2.

[0057] Furthermore, the upper edge of the first upper sealing plate 6 is sealed and welded to the inner edge on the front side of the upper frame edge 2b, the upper edge of the second upper sealing plate 7 is sealed and welded to the inner edge on the reverse side of the upper frame edge 2b, the two side edges of the first upper sealing plate 6 are respectively sealed and welded to the inner edges on the front side of the upper parts of the two side frame edges 2a1, and the two side edges of the second upper sealing plate 7 are respectively sealed and welded to the inner edges on the reverse side of the upper parts of the two side frame edges 2a1, so that the outer surfaces of the first upper sealing plate 6 and the second upper sealing plate 7 are respectively flush with the outer surfaces on the front and reverse sides of the anode plate frame 2. Furthermore, on the one hand, it provides favorable conditions for the sealing fit between the peripheries of the first diaphragm 8 and the second diaphragm 9 and the corresponding connection surfaces, and on the other hand, it is also beneficial to reduce the size of the integral anode described in the present invention in the thickness direction.

[0058] Furthermore, the upper frame edge 2b, the two side frame edges 2a1 and the bottom frame edge 2a2 are all U-shaped profile structures opening towards the inside of the anode plate frame 2, and U-shaped opening parts 2a11 are respectively formed at the upper ends of the two side frame edges 2a1. Flanges 2b2 extending horizontally outwards are respectively provided on both sides of the upper end wall of the upper frame edge 2b, and the flanges 2b2 are embedded in the corresponding U-shaped opening parts 2a11 and sealed and welded together therewith, so that the gas in the gas collecting chamber 10 will not overflow through the connection gap between the upper frame edge 2b and the two side frame edges 2a1.

[0059] In an embodiment of the present invention, the anode plate support 3 includes a plurality of rib plates 31 arranged in parallel at intervals along the width direction of the anode plate frame 2. The upper parts of each rib plate 31 extend into the gas collecting chamber 10, and a first installation groove 311 opening upwards is provided at the top end of each rib plate 31. The lower end of the conductive connecting member 5 is embedded in the first installation groove 311 of each rib plate 31 and welded and fixed thereto. The lower parts of each rib plate 31 extend into the upper end of the anode chamber 11, and a second installation groove 312 opening downwards is provided at the bottom end of each rib plate 31, and the second installation groove 312 constitutes the aforementioned anode plate installation part 300. The upper end of the anode plate 1 is embedded in the second installation groove 312 of each rib plate 31 and welded and fixed thereto. When the anode plate 1 is damaged or reaches the service life, only the solder joints at the upper end of the anode plate 1 need to be cut open, and then the anode plate 1 can be disassembled and replaced.

[0060] Furthermore, the two sides of the upper part of each rib plate 31 are respectively attached to the inner surfaces of the first sealing plate 6 and the second sealing plate 7, so as to provide support for the first sealing plate 6 and the second sealing plate 7 and improve the structural strength of the first sealing plate 6 and the second sealing plate 7. At the same time, ventilation holes 313 extending in the up and down direction are also engraved on the upper part of each rib plate 31, so that the gas entering the gas collecting chamber 10 can flow between the spaces 10a formed between every two adjacent rib plates 31. In other words, the fluid (i.e., gas or liquid) entering the gas collecting chamber 10 can flow in the internal space of the entire gas collecting chamber 10.

[0061] Furthermore, an installation hole 314 is provided in the upper part of each rib plate 31 between the ventilation hole 313 and the first installation groove 311. A steam pipe 20 horizontally penetrates through the installation holes 314 of each rib plate 31. One end of the steam pipe 20 penetrates through the upper side of the anode plate frame 2 and forms a steam inlet 20a. A plurality of steam outlets 20b are provided at intervals along the length direction on the pipe wall of the part of the steam pipe 20 located in the gas collection chamber 10. When crystallization occurs in the gas collection chamber 10 during use, steam can be introduced into the gas collection chamber through the steam pipe 20, so that the crystals dissolve and flow back into the anode chamber, thereby avoiding blockage of the fluid channel in the gas collection chamber by the crystals.

[0062] In an embodiment of the present invention, the anode plate 1 can be a titanium-based single mesh plate or a titanium-based double mesh plate, and a plug-in part 101 for inserting into and being welded and fixed to the second installation groove 312 of each rib plate 31 is formed at the upper end of the titanium-based single mesh plate or the titanium-based double mesh plate. At the same time, in order to improve the stability of the anode plate 1 in the anode chamber, several first abutting blocks 102 that abut against the inner sides of the aforementioned two side frame edges 2a1 can be respectively provided on both sides in the width direction of the anode plate 1, and several second abutting blocks 103 that abut against the inner sides of the aforementioned bottom frame edge 2a2 can be provided at the bottom of the anode plate 1.
