Description

Technical Field

[0001] The utility model relates to the technical field of electrowinning, and in particular to a louvered anode plate for nonferrous metal electrowinning, which has high electrolysis efficiency, low energy consumption and cost, and is convenient to clean and replace. Background Art

[0002] The electrolytic anode plate is a key component in the electrolysis process. The electrolytic anode plate is usually composed of three main parts: substrate, coating and connection part. Among them, the substrate is the main structure of the anode plate, bearing the weight and current of the entire anode plate. Therefore, the substrate structure design of the electrolytic anode plate should fully consider the actual needs of the electrolysis process, ensure uniform current distribution and a large enough anode reaction area, so as to improve the electrolysis efficiency, product quality and durability.

[0003] Traditional electrolytic anode plates generally use a rolled or cast whole lead alloy plate as a substrate. Since the lead alloy plate has low mechanical strength and is prone to peeling and cracking, in order to reduce the manufacturing cost of the anode plate, the plate is often thinned to reduce material costs. In addition, in order to increase the scale of production, the size of the plate is gradually increased, which causes the lead alloy anode plate to be easily deformed. This not only increases the workload of plate repair, but also easily causes inter-electrode short circuits after deformation, thereby increasing power consumption and reducing purification efficiency. In addition, the service life is only 8 to 10 months, resulting in high cost of use.

[0004] In the prior art, in order to overcome the problem of easy deformation of lead alloy anode plates, most companies adopt the method of increasing the thickness of anode plates to enhance the rigidity of the plates, but this will increase the manufacturing cost of anode plates and cannot completely solve the deformation problem of lead alloy anode plates. For this reason, titanium-based coated anodes are also used to overcome the shortcomings of lead alloy anodes, but the titanium in titanium-based anodes without an intermediate layer is easily passivated, resulting in difficulty in conducting electricity, and the high price of titanium makes the production cost high; although the use of titanium-based anodes containing intermediate layers can improve the firmness, conductivity and corrosion resistance of the anode to a certain extent, it further increases the cost, limiting the large-scale use of titanium-based coated anodes. In addition, there are also methods of providing circular holes instead of square holes on the substrate to improve the mechanical strength of the substrate under the condition of the same porosity; and enclosing rigid conductive parts in the substrate to improve the mechanical strength of the substrate, thereby achieving the purpose of suppressing the deformation of the plate to reduce power consumption and increase service life; but due to the limited mechanical strength of circular holes instead of square holes, the effect of suppressing the deformation of the plate is not obvious, and the rigid conductive parts enclosed in the substrate are complicated in manufacturing process due to the different properties of the materials, and the materials are easily delaminated, which makes the conductivity worse. In addition, fence-type anode plates are used to increase the current density of the anode plates, improve the flow properties of the electrolyte, and avoid the defect of the cathode plates touching the anode plates when they are lifted. However, the fence-type anode plates use insulating clamping strips to connect and fix the composite rods. The insulating strips are easily aged and deformed when immersed in the electrolyte for a long time, which is not conducive to the stability of the anode plate structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a louver-shaped anode plate for nonferrous metal electrolysis, which has high electrolysis efficiency, low energy consumption and cost, and is convenient to clean and replace.

[0006] The utility model is implemented as follows: comprising a conductive beam and a copper rod, wherein the middle portion of the copper rod is wrapped in the conductive beam;

[0007] It also includes a conductive side plate and a conductive blade. Two of the conductive side plates are arranged in parallel below the conductive beam.

The two ends of the conductive blades are respectively fixedly connected to the conductive side plates on the corresponding sides.

[0008] Furthermore, the bottom end of the upper conductive blade of the adjacent conductive blades is higher than the top end of the lower conductive blade to form a flow guide gap.

[0010] Furthermore, the conductive blades from top to bottom between the two conductive side plates are arranged to be inclined in the same direction and at the same inclination angle, or the conductive blades from top to bottom are arranged to be inclined in the same direction and at different inclination angles.

[0011] Furthermore, two ends of the conductive blade are respectively welded or detachably fixedly connected to the conductive side plates on the corresponding sides.

[0012] Furthermore, the conductive side plate is provided with a plurality of through holes at intervals along the length direction, screw holes are respectively provided at both ends of the conductive blade, and the conductive blade and the conductive side plate are connected by screws passing through the through holes and cooperating with the screw holes.

[0013] Furthermore, a plurality of oblique grooves are arranged at intervals along the length direction on the opposite inner sides of the two conductive side plates, and the two ends of the conductive blades are slidably inserted into the oblique grooves of the corresponding side conductive side plates, and a connecting rod is detachably connected between the two conductive side plates away from and / or close to the conductive beam.

[0014] Furthermore, a blank area is formed between the topmost conductive blade between the two conductive side plates and the bottom end of the conductive beam.

[0017] Beneficial effects of the utility model:

[0018] 1. The utility model innovatively adopts a structure in which a plurality of conductive blades are arranged obliquely between conductive side plates on both sides to form a substrate, and then a complete anode plate is formed by fixing the conductive side plates to the conductive beams at the top. This can not only significantly increase the actual conductive area of ​​the anode plate, but also reduce the actual current density of the anode plate, thereby reducing the cell voltage to achieve reduced power consumption; the substrate structure can also promote the flow and uniform distribution of the electrolyte, making the fluidity and circulation of the electrolyte more sufficient, which is beneficial to reducing concentration polarization to improve the efficiency of electrolysis; and the adjacent conductive blades arranged obliquely form a gap, so that the flow rate of the electrolyte becomes larger after entering the gap, and even forms a small turbulence, so that the anode mud deposited on the surface of the conductive blade can be taken away, which can not only reduce the problem of plate short circuit caused by excessive anode mud deposition, but also further improve the electrolysis efficiency.

[0019] 2. The substrate of the utility model is composed of a plurality of conductive blades fixedly connected to the conductive side plates, thereby decomposing the entire substrate into a plurality of smaller conductive blades, which can reduce or even avoid the stress deformation problem that is prone to occur in conventional large-size integral plates, effectively reduce the workload of plate repair and the inter-electrode short circuit after deformation, reduce the power consumption of electrolysis and increase the service life of the substrate, and ultimately reduce the use cost of the anode plate. In addition, the manufacturing process of the conductive side plates and the conductive blades is simple, which is also convenient for controlling the overall cost of the anode plate.

[0020] 3. The utility model further connects the two ends of the conductive blade to the conductive side plates on the corresponding sides in a detachable fixed manner, so that each conductive blade can be disassembled and installed separately, which is convenient for cleaning the blades and timely replacing the corresponding conductive blades according to the deformation conditions, thereby reducing the use cost of the anode plate and avoiding inter-electrode short circuits. Moreover, the deformed conductive blades are also easy to repair after being removed.

[0021] Therefore, the utility model has the characteristics of high electrolysis efficiency, low energy consumption and cost, and convenient cleaning and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figures 1 to 4 As shown, the utility model comprises a conductive beam 1 and a copper rod 2, wherein the middle portion of the copper rod 2 is wrapped in the conductive beam 1;

[0029] It also includes a conductive side plate 3 and a conductive blade 4. The two conductive side plates 3 are arranged in parallel below the conductive beam 1. The top of the conductive side plate 3 is fixedly connected to the conductive beam 1. A plurality of conductive blades 4 are arranged obliquely at intervals from top to bottom between the two conductive side plates 3. The two ends of the conductive blade 4 are respectively fixedly connected to the conductive side plates 3 on the corresponding sides.

[0030] The composition of the conductive side plate 3 and the conductive blade 4 meets the chemical composition requirements of "Lead Anode Plate for Electrolytic Deposition (YS / T 498)".

[0031] The bottom end of the upper conductive blade 4 adjacent to the conductive blade 4 is higher than the top end of the lower conductive blade 4 to form a flow guide gap 9.

[0032] The conductive blades 4 from top to bottom between the two conductive side plates 3 are tilted in the same direction, the adjacent conductive blades 4 are tilted in opposite directions, or the conductive blades 4 in the upper and lower parts are tilted in opposite directions.

[0033] The conductive blades 4 between the two conductive side plates 3 are arranged to be inclined in the same direction and at the same inclination angle from top to bottom, or the conductive blades 4 are arranged to be inclined in the same direction and at different inclination angles from top to bottom.

[0034] The two ends of the conductive blade 4 are respectively welded or detachably fixedly connected to the conductive side plate 3 on the corresponding side.

[0035] The conductive side plate 3 is provided with a plurality of through holes at intervals along the length direction, and screw holes are provided at both ends of the conductive blade 4. The conductive blade 4 is connected to the conductive side plate 3 by screws 5 that pass through the through holes and match the screw holes.

[0036] The inner sides of the two conductive side plates 3 facing each other are provided with a plurality of inclined grooves 6 at intervals along the length direction, and the two ends of the conductive blade 4 are respectively slidably inserted into the inclined grooves 6 of the conductive side plates 3 on the corresponding side, and a connecting rod 8 is detachably connected between the two conductive side plates 3 at a position away from and / or close to the conductive beam 1. The two ends of the conductive blade 4 are respectively slidably inserted into the inclined grooves 6 of the conductive side plates 3 on the corresponding side, and then the distance between the two conductive side plates 3 is adjusted by the connecting rod 8, so that the two conductive side plates 3 clamp the conductive blades 4 therebetween.

[0037] The connecting rod 8 is fixedly connected to the conductive side plate 3 via connecting screws, and the length of the connecting rod 8 is smaller than the inner side spacing of the two conductive side plates 3 when the conductive blades 4 are clamped.

[0038] At least one end of the conductive blade 4 is tightly fitted and slidably inserted into the inclined groove 6 of the conductive side plate 3 on the corresponding side.

[0039] Both ends of the connecting rod 8 are fixedly connected to the corresponding side conductive side plates 3 via connecting screws.

[0040] A blank area 7 is formed between the topmost conductive blade 4 between the two conductive side plates 3 and the bottom end of the conductive beam 1. Since there is no obstacle of the conductive blade 4 in the blank area 7, it can be used as a hoisting space for the anode plate to avoid manual lifting of the anode plate, thereby reducing the labor intensity of the anode plate installation and improving the installation efficiency.

[0041] The surface of the conductive side plate 3 and / or the conductive blade 4 is provided with a plurality of ribs extending along the length direction at intervals.

[0042] The conductive side plate 3 and / or conductive blade 4 are composed of a rigid frame and a lead alloy layer wrapping the rigid frame, the rigid frame is a rod-shaped or plate-shaped structure composed of copper, aluminum, silver, iron or alloys of the aforementioned metals, and the top of the rigid frame of the conductive side plate 3 is welded to the copper rod 2 in the conductive beam 1. The rigid frame is buried inside the conductive side plate 3 and / or the conductive blade 4, which can effectively improve the mechanical strength of the corresponding conductive side plate 3 and the conductive blade 4, overcome the disadvantage that the lead alloy is easy to deform, and greatly improve the service life of the anode plate.

[0043] An anti-corrosion plastic layer is applied between the liquid level of the conductive side plate 3 and the bottom end of the conductive beam 1 .

[0044] The production process of this utility model is as follows:

[0045] like Figure 4 As shown, a layer of lead alloy is coated on the middle surface of the copper rod 2 which has been surface treated by a continuous spiral lead alloy die-casting machine to obtain a composite conductive beam 1 of a copper core lead-based alloy; at the same time, the conductive side plate 3 and the conductive blade 4 are processed according to the design size, and then the top ends of the two conductive side plates 3 are respectively welded and fixed to the conductive beam 1, and an anti-corrosion plastic layer is applied between the liquid level line of the conductive side plate 3 and the bottom end of the conductive beam 1; then the conductive blade 4 is respectively fixed obliquely between the two conductive side plates 3 by screws 5, and a blank area 7 is formed between the topmost conductive blade 4 between the two conductive side plates 3 and the bottom end of the conductive beam 1 as a lifting groove, and finally a louver-type anode plate is formed.

[0046] During the use of the anode plate, if it is found during maintenance that the deformation of some conductive blades 4 or the anode mud deposited on the surface exceeds the standard, the anode plate can be lifted out, and then the screws 5 at both ends of the corresponding conductive blade 4 can be loosened, and the corresponding conductive blade 4 can be removed for repair, replacement or cleaning. After completion, the conductive blade 4 is fixed and reset with the screws 5.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
