Description

Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0062] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0063] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0064] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a high-position partition gas collection device for an electrolytic cell, including: an electrolytic cell 1 and a gas collection assembly installed on the top of the electrolytic cell 1. The gas collection assembly includes: a tank cover assembly 2, a smoke collection hood 3, two flue gas diversion plates 4, a first smoke pipe 5, a second smoke pipe 6, a main smoke pipe 7, an auxiliary treatment mechanism 8 and a flow control valve 9. The tank cover assembly 2 is installed on the top of the electrolytic cell 1 through a sealing assembly 21. The smoke collection hood 3 is installed on the top of the tank cover assembly 2. The top of the smoke collection hood 3 has an opening 31. At the bottom of the opening 31, there is a first installation hole 32 for installing a crust breaking and feeding machine. The side of the smoke collection hood 3 facing the electrolytic cell 1 has a first flue 33 and a second flue 34. The first flue 33 and the second flue are located on both sides of the opening 31. The flue gas diversion plates 4 are installed along the length direction of the smoke collection hood 3 and are located on opposite sides of the first installation hole 32. The first smoke pipe 5 is installed in the first flue 33. Along the axial direction of the first smoke pipe 5, there are a number of first air hoods 51. The second smoke pipe 6 is installed in the second flue 34. Along the axial direction of the second smoke pipe 6, there are a number of second air hoods 61. The main smoke pipe 7 is installed at the smoke outlet ends of the first smoke pipe 5 and the second smoke pipe 6. The smoke outlet end of the main smoke pipe 7 has an emission port 71 and an auxiliary treatment port 72. The auxiliary treatment mechanism 8 is connected to the auxiliary treatment port 72 through a pipeline. An automatic valve is provided on the pipeline, and the automatic valve is normally closed. The flow control valve 9 is installed at the emission port 71.

[0065] During use, the gas collection device is connected to the top of the electrolytic cell 1 through the sealing assembly 21, so that a reaction area is formed between the electrolytic cell 1 and the gas collection device, and aluminum is processed in the reaction area. The flue gas generated during the processing rises towards the top of the reaction area and is separated by the flue gas diversion plates 4 provided on the smoke collection hood 3 during the rising process, so that the flue gas is diverted into the first flue 33 and the second flue 34. The first smoke pipe 5 and the second smoke pipe 6 are respectively installed in the first flue 33 and the second flue 34. After the flue gas reaches a certain level, it is introduced into the first flue 33 and the second flue 34 through the first air hoods 51 and the second air hoods 61 provided on the first smoke pipe 5 and the second smoke pipe 6. The flue gas is sent into the main smoke pipe 7 through the first flue 33 and the second flue 34. The main smoke pipe 7 sends the fluorine-containing gas into a gas treatment device for treatment, and is discharged after reaching the standard, avoiding physical damage to workers in the workshop and environmental pollution. The flow control valve 9 provided at the emission port of the main smoke pipe 7 is for conveniently adjusting the emission amount and avoiding the problem of excessive emission.

[0066] During the treatment process, the pressure in the reaction area increases sharply, and it is necessary to quickly discharge the flue gas to reduce the pressure. However, when the gas treatment device reaches its upper limit, the automatic valve connected to the main smoke pipe 7 is opened, and the excess gas is discharged into the auxiliary treatment mechanism 8 for treatment, further reducing the risk of directly discharging the fluorine-containing gas into the atmosphere in the factory area.

[0067] It should be noted that both the gas treatment device and the auxiliary treatment mechanism 8 are existing gas treatment equipment, which can be understood as gas filters.

[0068] The first flue pipe 5 and the second flue pipe 6 of the equipment are arranged at the top of the smoke collecting hood 3, making full use of the upper structural space, so that the structure of the whole device is compact and beautiful. At the same time, the structure of high-position gas collection is adopted, which is convenient for replacing the anode and provides more sufficient operation space for processes such as tapping aluminum.

[0069] The two flue gas diversion plates 4 divert the rising flue gas to the lower parts of the first air hood 51 and the second air hood 61, facilitating the rapid entry of the flue gas into the first flue pipe 5 and the second flue pipe 6, and discharging through the main flue pipe 7 connected to the first flue pipe 5 and the second flue pipe 6.

[0070] In another embodiment, as Figure 1 shown, the sealing component 21 includes: a first sealing strip 22 and a second sealing strip 24. The first sealing strip 22 is arranged along the top edge of the electrolytic cell 1. After installation, the head and tail of the first sealing strip 22 are connected end to end, and a sealing groove 23 is provided at the top of the first sealing strip 22. The second sealing strip 24 is arranged along the bottom edge of the tank cover assembly 2. After installation, the head and tail of the second sealing strip are connected end to end, and a sealing rib 25 matching the sealing groove 23 is provided at the bottom of the second sealing strip 24.

[0071] The sealing groove 23 is provided on the first sealing strip 22 and the sealing rib 25 is provided on the second sealing strip 24 for the convenience of positioning during buckling. After installation, the sealing rib 25 on the second sealing strip 24 is located in the sealing groove 23 of the first sealing strip 22, facilitating the sealing of the gas collection device and the electrolytic cell 1.

[0072] In another embodiment, as Figure 2 and Figure 3 shown, the smoke collecting hood 3 includes: a top plate 35, two connecting plates 36 and a transition plate 39. Two protrusions are processed on the top plate 35. On the side of the two protrusions facing the electrolytic cell 1, a first flue 33 and a second flue 34 are formed, and an opening 31 is formed between the two protrusions. The two connecting plates 36 are fixedly arranged on both sides of the top plate 35 along its length direction. At the top of the end of the connecting plate 36 away from the top plate 35, an installation opening 38 is provided. One end of the transition plate 39 is provided with an installation part 310 matching the installation opening 38, the other end of the transition plate 39 is connected to the tank cover assembly 2, and a second installation hole 37 for installing the anode rod is provided on the transition plate 39.

[0073] The top plate 35 and the two connecting plates 36 are formed by stamping a single plate. After stamping, two protrusions are formed, and an opening 31 is formed between the two protrusions. A first mounting hole 32 for installing the crust breaking and feeding machine is provided in the opening 31. On one side of the two connecting plates 36 close to the protrusions, second mounting holes 37 for installing the anode guide rod are provided.

A transition plate 39 is used to connect the connecting plate 36 and the tank cover assembly 2, and a mounting member 310 matching the mounting opening 38 is provided on the transition plate 39.

[0074] More specifically, the mounting member 310 is embedded in the mounting opening 38 and locked by screws, and a sealing gasket is provided at the connection between the transition plate 39 and the connecting plate 36. This improves the sealing performance during use and reduces the risk of fluorine-containing gas leaking from each connection.

[0075] In another embodiment, as Figure 2 and Figure 3 shown, in order to conveniently separate the inlets of the first flue pipe 5 and the second flue pipe 6, a plurality of baffles 311 are sequentially arranged along the axial directions of the first flue 33 and the second flue 34. The anode guide rod is installed between the two baffles 311 arranged in rows.

[0076] Partitioning is carried out through the partition plate, and at the same time, it is combined with the high-position gas collection structure, which reduces the resistance during the gas collection process, has a high self-flow utilization rate of the air pressure temperature difference, and a high gas capture efficiency.

[0077] More specifically, the baffle 311 is made of a ceramic plate because of the good corrosion resistance and non-conductive properties of the ceramic plate.

[0078] In another embodiment, as Figure 1 、 Figure 5 and Figure 6 shown, in order to make the gas collection device relatively sealed with the electrolytic cell 1 after installing the anode guide rod and the crust breaking and feeding machine, a sealing mechanism 10 is provided in both the first mounting hole 32 and the second mounting hole 37.

[0079] In another embodiment, as Figure 5 and Figure 6As shown in the figure, the sealing mechanism 10 includes: a sealing ring 101, a main seal 105, an auxiliary seal 106 and a sealing ring 107. The sealing ring 101 is fixedly installed on the top of the fume hood 3. A first installation groove 102, a second installation groove 103 and a third installation groove 104 are provided on the surface of the sealing ring 101 that cooperates with the anode rod or the tapping and feeding machine. The main seal 105 is installed in the first installation groove 102, and a through hole for the anode rod or the tapping and feeding machine to pass through is provided in the middle of the main seal 105. The auxiliary seal 106 is installed in the second installation groove 103, and serrated contact teeth are provided on one side wall of the auxiliary seal 106 that contacts the anode rod or the tapping and feeding machine. The sealing ring 107 is installed in the third installation groove 104. Among them, the first installation groove 102, the second installation groove 103 and the third installation groove 104 are arranged in sequence from the outside to the inside of the fume hood 3.

[0080] During use, the main seal 105 makes surface contact with the anode rod or the tapping and feeding machine to improve its sealing performance. The auxiliary seal 106 and the sealing ring 107 make line contact with the anode rod or the tapping and feeding machine, further improving the sealing performance of the sealing mechanism 10.

[0081] In another embodiment, as Figure 6 shown, in order to facilitate the installation of the positioning member 109, a positioning hole 108 is provided at the end of the sealing ring 101 where the first installation groove 102 is located. The positioning member 109 is in an "┐" shape and is installed between the main seal 105 and the first installation groove 102. In order to facilitate the adjustment of the position of the positioning member 109, a long circular hole 110 that cooperates with the positioning hole 108 is provided on the horizontal plate of the positioning member 109. The positioning member 109 is provided to make the main seal 105 fit more closely with the anode rod or the tapping and feeding machine.

[0082] In another embodiment, as Figure 6 shown, in order to more conveniently adjust the position of the positioning member 109 and at the same time reduce the gap between the positioning member 109 and the installation groove, an adjusting member 111 is provided between the positioning member 109 and the first installation groove 102.

[0083] In another embodiment, in order to make the pressure in the reaction area evenly distributed, the smoke inlet volume of each first smoke pipe 5 and second smoke pipe 6 is adjustable.

[0084] More specifically, the valve flow rates installed on the first air hood 51 and the second air hood 61 are controlled according to the detected data, so as to make the pressure evenly distributed within the reaction area. At the same time, the flow rates of the first air hood 51 and the second air hood 61 are adjustable, which is convenient for quickly discharging the excess flue gas when pressure relief is required, and improving the safety performance of the electrolysis device during use. It should be noted that flow regulating valves are installed on the air inlet pipes of the first air hood 52 and the second air hood 61. The pressure of each area is adjusted by the flow regulating valves at the air inlets of each air hood, so that the pressure within each reaction area is evenly distributed.

[0085] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
