Description

Technical Field

[0001] This utility model relates to the field of anode plate technology, and in particular to an anode that can prevent crystallization blockage in the intake chamber. Background Technology

[0002] Chinese utility model patent CN212610931U discloses an insoluble frame-shaped anode structure for collecting acid mist. It includes a frame-shaped anode with connecting ribs fixed to it. A conductive screw is threaded to the top of the connecting ribs, and a conductive beam is connected to the upper end of the conductive screw. A gas collection hood is fixed between the connecting ribs and the conductive screw. An isolation membrane, pocket-shaped and matching the size of the isolation membrane, is sealed to the lower edge of the gas collection hood, completely enclosing the frame-shaped anode within the sealed space formed by the gas collection hood and the isolation membrane. An acid mist outlet is provided on one side of the gas collection hood, connected to an exhaust fan or negative pressure pump. This allows for ventilation at the acid mist outlet, enabling the acid mist to be directly drawn out and collected for treatment, thus preventing the acid mist from being directly released into the environment during the electrowinning process.

[0003] While this anode structure can effectively extract and collect acid mist generated during operation, it is prone to crystallization and blockage within the collection hood after prolonged use. This blockage obstructs the airflow within the collection hood, hindering the extraction of acid mist. Therefore, improvements are needed from relevant professionals. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anode that can prevent crystallization blockage in the intake chamber, has a reasonable and reliable structural design, and high working efficiency, thereby ensuring the reliability of acid mist extraction during the use of the anode.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An anode for preventing crystallization blockage in the intake chamber includes an anode chamber, an anode plate, an intake chamber, and a steam pipe. The anode plate is placed inside the anode chamber, and the intake chamber is located above the anode chamber, with its lower end connected to the upper end of the anode chamber. An outlet is provided on one side of the intake chamber. The left-right direction of the intake chamber is defined as its width direction, and the front-back direction of the intake chamber is defined as its thickness direction. The width dimension of the intake chamber is greater than its thickness dimension. One end of the steam pipe extends into the intake chamber from one side of its width direction and extends to the other side of its width direction. The end of the steam pipe extending into the intake chamber has a plurality of steam outlets spaced apart along its extension direction. The other end of the steam pipe is exposed outside the intake chamber and has a steam inlet.

[0007] Furthermore, it also includes a conductive beam, which is located above the air intake chamber, and the steam pipe is arranged parallel to the conductive beam.

[0008] Furthermore, it also includes an anode plate support and a conductive connecting plate. The upper part of the anode plate support extends into the suction chamber, and the end of the steam pipe extending into the suction chamber passes through at least a portion of the upper part of the anode plate support. The lower part of the anode plate support extends into the anode chamber, and the upper end of the anode plate is fixedly connected to the lower part of the anode plate support. The upper end of the conductive connecting plate is connected to the conductive beam, and the lower end of the conductive connecting plate extends into the suction chamber and is connected to the upper part of the anode plate support.

[0009] Furthermore, the anode plate support includes a plurality of ribs arranged parallel to each other along the width direction of the suction chamber; the upper part of each rib extends into the suction chamber, the lower part of each rib extends into the anode chamber, and a suction channel is formed between two adjacent ribs; each rib has a mounting hole cut out at its upper part, and the end of the steam pipe that extends into the suction chamber passes through the mounting hole of each rib laterally, and at least one steam outlet is provided on the pipe wall at the end of the steam pipe that extends into the suction chamber at a position corresponding to each suction channel.

[0010] Furthermore, each stiffener is also provided with ventilation holes extending in the vertical direction at the top, so that the air intake channels can be interconnected.

[0011] Furthermore, all vents are located on the same horizontal line, and each vent is located below its corresponding mounting hole.

[0012] Furthermore, each stiffener has a first mounting groove with an upward opening at its top, and the lower end of the conductive connecting plate is embedded in the first mounting groove of each stiffener and welded to it; each stiffener has a second mounting groove with a downward opening at its bottom, and the upper end of the anode plate is embedded in the second mounting groove of each stiffener and welded to it.

[0013] Furthermore, the upper wall of the air intake chamber is provided with an opening for the lower end of the conductive connecting plate to extend into the air intake chamber. The opening has a shape that matches the outer peripheral surface contour of the conductive connecting plate, and the conductive connecting plate is welded to the opening along its outer periphery.

[0014] Furthermore, the steam pipe is positioned higher than the air outlet, and all steam outlets are positioned downwards; alternatively, some steam outlets are positioned downwards, while others are positioned upwards.

[0015] Furthermore, the air outlet is also located on one side of the width direction of the air intake chamber, and a liquid outlet is also provided on the side of the air intake chamber opposite to the air outlet.

[0016] The beneficial effects of this utility model are as follows:

[0017] First, since a steam pipe is installed in the suction chamber, when crystallization occurs in the suction chamber, steam can be introduced into the suction chamber through the steam pipe, thereby dissolving the crystals and allowing them to flow back into the anode chamber. This prevents the suction channel in the suction chamber from being blocked by the crystals, thus ensuring the reliability of acid mist extraction during the use of the anode.

[0018] Secondly, since the steam pipe extends from one side of the suction chamber to the other side, and the insertion end of the steam pipe is provided with several steam outlets at intervals along its extension direction, the coverage and speed of steam when it enters the suction chamber can be increased, thereby enabling the crystals in the suction chamber to be dissolved quickly and fully, thus improving work efficiency.

[0025] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0026] like Figures 1 to 6As shown in the figure, the anode described in this embodiment, which can prevent crystallization and blockage in the suction chamber, includes an anode chamber 1, an anode plate 2, a suction chamber 3, and a steam pipe 4. The anode plate 2 is placed inside the anode chamber 1, and the suction chamber 3 is located above the anode chamber 1, with its lower end connected to the upper end of the anode chamber 1. An outlet 5 is provided on one side of the suction chamber 3, and the outlet 5 can be connected to an external suction device to remove and treat the acid mist entering the suction chamber 3.

[0027] The left-right direction of the suction chamber 3 is defined as the width direction W, and the front-back direction of the suction chamber 3 is defined as the thickness direction T. The width dimension W1 of the suction chamber 3 is greater than the thickness dimension T1. One end 4a of the steam pipe 4 extends into the suction chamber 3 from the width direction W side and extends to the other side of the width direction W of the suction chamber 3. The end 4a of the steam pipe 4 that extends into the suction chamber has several steam outlets 4a1 at intervals along its extension direction. The other end 4b of the steam pipe 4 is exposed outside the suction chamber 3 and has a steam inlet 4b1. The steam inlet 4b1 can be connected to a steam device.

[0028] The acid mist generated by the anode plate 2 during operation flows upward from the anode chamber 1 into the suction chamber 3, and is then drawn out to an external collection device for cleaning via the suction device connected to the outlet 5. When crystallization occurs in the suction chamber 3, steam can be introduced into the steam pipe 4 through the steam inlet 4b1. Simultaneously, the steam introduced into the steam pipe 4 is discharged into the suction chamber 3 through each steam outlet 4a1, thereby dissolving the crystals in the suction chamber 3 and allowing them to flow back into the anode chamber. This prevents the suction channel in the suction chamber 3 from being blocked by crystals, thus preventing the acid mist from being drawn out. Furthermore, since there are multiple steam outlets 4b1 arranged at intervals along the extension direction of the steam pipe 4, the coverage and speed of steam entering the suction chamber 3 can be increased, allowing the crystals generated in various locations within the suction chamber 3 to be dissolved quickly and completely, thereby improving working efficiency.

[0029] In this embodiment, the anode further includes a conductive beam 6, an anode plate support 7, and a conductive connecting plate 8. The conductive beam 6 is located above the suction chamber 3, and the steam pipe 4 is arranged parallel to the conductive beam 6. The upper part of the anode plate support 7 extends into the suction chamber 3, and the end 4a of the steam pipe 4 extending into the suction chamber passes through at least a portion of the upper part of the anode plate support 7. The lower part of the anode plate support 7 extends into the anode chamber 1, and the upper end of the anode plate 2 is fixedly connected to the lower part of the anode plate support 7. The upper end of the conductive connecting plate 8 is connected to the conductive beam 6, and the lower end of the conductive connecting plate 8 extends into the suction chamber 3 and is connected to the upper part of the anode plate support 7.

[0030] The conductive connecting plate 8, the anode plate support 7, and the anode plate 2 are all made of titanium or titanium alloy, thus possessing excellent electrical conductivity and corrosion resistance. After the conductive beam 6 is energized, the anode plate 2 becomes conductive through the electrical conduction of the conductive connecting plate 8 and the anode plate support 7.

[0031] Specifically, the anode plate support 7 includes several ribs 71 arranged parallel to each other along the width W of the intake chamber 3. The upper part of each rib 71 extends into the intake chamber, and the lower part of each rib 71 extends into the anode chamber 1, forming an intake channel 70 between two adjacent ribs 71. Each rib 71 has a mounting hole 711 cut out at its upper part. The end 4a of the steam pipe 4 extending into the intake chamber 3 passes laterally through the mounting hole 711 of each rib 71, and at least one steam outlet 4a1 is provided on the pipe wall of the end 4a of the steam pipe 4 extending into the intake chamber 3 at a position corresponding to each intake channel 70, so that steam can quickly enter each intake channel 70.

[0032] Each stiffener 71 is also provided with a vent 712 extending vertically at its upper part, so that the intake channels 70 are interconnected, and the acid mist entering each intake channel 70 can be drawn out through the outlet 5. Preferably, all vents 712 are located on the same horizontal line, and all vents 712 are located below the corresponding mounting hole 711.

[0033] Each stiffener 71 has a first mounting groove 713 with an upward opening at its top. The lower end of the conductive connecting plate 8 is embedded in the first mounting groove 713 of each stiffener 71 and welded to it. Each stiffener 71 has a second mounting groove 714 with a downward opening at its bottom. The upper end of the anode plate 2 is embedded in the second mounting groove 714 of each stiffener 71 and welded to it.

[0034] The upper wall of the air intake chamber 3 is provided with an opening 31 for the lower end of the conductive connecting plate 8 to extend into the air intake chamber 3. The opening 31 has a shape that matches the outer peripheral surface contour of the conductive connecting plate 8, and the conductive connecting plate 8 is welded to the opening 31 along its outer periphery, so that the gas in the air intake chamber 3 will not overflow outward through the opening 31.

[0035] Preferably, the steam pipe 4 is positioned higher than the outlet 5, and all steam outlets 4a1 are positioned downwards; alternatively, some of the steam outlets 4a1 are positioned downwards, while others are positioned upwards.

[0036] Preferably, the air outlet 5 is also located on one side of the width direction of the air intake chamber 3, and the air intake chamber 3 is also provided with a liquid outlet 9 on the side opposite to the air outlet 5.

[0037] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
