[0031] The embodiments of the application are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the application are described in detail below.

[0033] In the description of this application, "multiple" means two or more.

[0034] The following description, in conjunction with the accompanying drawings, describes an electrolytic cell cooling device 1 according to an embodiment of this application.

[0035] like Figures 1-4 As shown, the electrolytic cell cooling device 1 according to an embodiment of this application includes a compressed air pipe 100, a guide pipe 200, an outlet pipe 300, a solenoid valve 400, and a time-type switch 500.

[0036] The air guide pipe 200 has a first end 201 and a second end 202 arranged opposite to each other. The first end 201 is connected to the compressed air pipe 100. The air outlet pipe 300 is connected to the second end 202 and has multiple air outlets 310. The multiple air outlets 310 are arranged at intervals along the length of the electrolytic cell 2, and the air outlets 310 spray air into the shell of the electrolytic cell 2. The solenoid valve 400 is provided in the compressed air pipe 100 and / or the air guide pipe 200, and the solenoid valve 400 is used to control the air flow between the compressed air pipe 100 and the air outlet pipe 300. The time-type switch 500 is connected to the solenoid valve 400 and is used to control the start and stop of the solenoid valve 400.

[0037] For example, the compressed air pipe 100 can be connected to a compressed air source, which can be a compressed air tank or an air compressor, or other device capable of storing or producing compressed air. Alternatively, the compressed air pipe 100 can integrate a compressed air source.

[0038] According to the embodiment of this application, the electrolytic cell cooling device 1 is equipped with a compressed air pipe 100 to transport compressed air. The compressed air pipe 100 has strong pressure resistance and a smooth inner wall. The air guide pipe 200 can guide the compressed air in the compressed air pipe 100 to the air outlet pipe 300, so as to realize the air cooling of the electrolytic cell 2 by the air outlet pipe 300.

[0039] Additionally, the solenoid valve 400 can be located at the end of the compressed air pipe 100 that connects to the air guide pipe 200. When the solenoid valve 400 is closed, the compressed air pipe 100 is disconnected from the air guide pipe 200, and the compressed air in the compressed air pipe 100 will not flow into the air guide pipe 200; when the solenoid valve 400 is open, the compressed air pipe 100 is connected to the air guide pipe 200, and the compressed air in the compressed air pipe 100 can flow into the air guide pipe 200 and then into the outlet pipe 300.

[0040] Alternatively, the electromagnetic valve 400 can be arranged in the air guide pipe 200. When the electromagnetic valve 400 is closed, the compressed air pipe 100 and the air guide pipe 200 can be in communication, but the compressed air pipe 100 and the air outlet pipe 300 are disconnected, and the compressed air of the compressed air pipe 100 cannot flow into the air outlet pipe 300; when the electromagnetic valve 400 is opened, the compressed air pipe 100 and the air outlet pipe 300 are in communication, and the compressed air of the compressed air pipe 100 can flow into the air guide pipe 200 and then into the air outlet pipe 300. Moreover, the distance between the electromagnetic valve 400 and the compressed air pipe 100 is increased, and the kinetic energy of the compressed air flowing to the electromagnetic valve 400 is reduced, thereby reducing the damage probability of the electromagnetic valve 400.

[0041] By controlling the opening and closing of the electromagnetic valve 400, whether the electrolytic cell air cooling device 1 blows air to the electrolytic cell 2 can be realized, and the air volume of the electrolytic cell air cooling device 1 can be effectively controlled. Moreover, the electromagnetic valve 400 is controlled by an electric signal, and manual operation by an operator is not required, thereby improving the degree of automation.

[0042] In addition, the time switch appliance 500 is connected with the electromagnetic valve 400, and the time switch appliance 500 is used to control the start and stop of the electromagnetic valve 400. The time switch appliance 500 can be a time relay, a time control switch or the like, which is controlled according to the running time. For example, the time switch appliance 500 controls the electromagnetic valve 400 to open every first preset time, so that the electrolytic cell air cooling device 1 blows air to the electrolytic cell 2 for cooling, and then the time switch appliance 500 controls the electromagnetic valve 400 to close after a second preset time, so that the electrolytic cell air cooling device 1 stops blowing air to the electrolytic cell 2. The first preset time can be 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds, 65 seconds, 70 seconds, 75 seconds, 80 seconds, 85 seconds, 90 seconds or 95 seconds. The second preset time can be 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds, 65 seconds, 70 seconds, 75 seconds, 80 seconds, 85 seconds, 90 seconds or 95 seconds.

[0043] By arranging the time switch appliance 500, the start and stop of the electromagnetic valve 400 are intermittently controlled, the electrolytic cell 2 is intermittently cooled, the electrolytic cell 2 is prevented from being damaged due to the high temperature of the electrolytic cell 2, the electrolytic cell air cooling device 1 is prevented from blowing air for a long time, the air source is not wasted, and the wear rate of the compressed air pipe 100, the air guide pipe 200, the air outlet pipe 300 and the electromagnetic valve 400 is reduced.

[0044] In this way, the electrolytic cell air cooling device 1 according to the embodiment of the present application can intermittently blow air to cool the electrolytic cell 2, the temperature of the electrolytic cell 2 can be kept low, the energy source can be prevented from being wasted, and the damage rate of the pipeline and the valve body is reduced.

[0045] AsFigure 1 As shown, the electrolytic cell cooling device 1 further includes a first manual valve 610 and a second manual valve 620. The first manual valve 610 and the second manual valve 620 can be ball valves.

[0046] A first manual valve 610 is located at the first end 201 and is used to control the air flow between the compressed air pipe 100 and the air guide pipe 200. A second manual valve 620 is located at the second end 202 and is used to control the air flow between the air guide pipe 200 and the air outlet pipe 300.

[0047] By setting a first manual valve 610, the operator can open and close the first manual valve 610. When the first manual valve 610 is open, the compressed air pipe 100 and the air guide pipe 200 are connected; when the first manual valve 610 is closed, the connection between the compressed air pipe 100 and the air guide pipe 200 is disconnected. By setting a second manual valve 620, the operator can open and close the second manual valve 620. When the second manual valve 620 is open, the air outlet pipe 300 and the air guide pipe 200 are connected; when the second manual valve 620 is closed, the connection between the air outlet pipe 300 and the air guide pipe 200 is disconnected.

[0048] In this way, compressed air in compressed air pipe 100 can only enter air outlet pipe 300 through air guide pipe 200 when both the first manual valve 610 and the second manual valve 620 are open, reducing the probability of compressed air in compressed air pipe 100 accidentally leaking from air outlet pipe 300. Furthermore, since the first manual valve 610 and the second manual valve 620 are located at both ends of air guide pipe 200, it is convenient for operators to adjust the connection between compressed air pipe 100 and air guide pipe 200, as well as the connection between air guide pipe 200 and air outlet pipe 300.

[0049] In addition, by setting a time-controlled switch 500 to intermittently control the start and stop of the solenoid valve 400, the electrolytic cell 2 can be cooled intermittently, thereby reducing the wear rate of the first manual valve 610 and the second manual valve 620.

[0050] like Figure 1 As shown, the above-mentioned vent pipe 300 is located below the electrolytic cell 2, and the vent pipe 300 is spaced apart from the electrolytic cell 2. The vent outlet 310 is located on the upper wall of the vent pipe 300. In this way, the vent pipe 300 mainly cools the bottom wall of the electrolytic cell 2, reduces the probability of the bottom wall of the electrolytic cell 2 being damaged by heat, prevents the aluminum liquid or electrolyte in the electrolytic cell 2 from flowing downward under the action of gravity, and ensures that the electrolyte can be effectively stored in the electrolytic cell 2.

[0051] In addition, the lower wall of the air outlet pipe 300 is provided with the air inlet 320, and the air inlet 320 is connected with the second end 202. In this way, the air guide pipe 200 and the electrolytic cell 2 are arranged on the upper and lower sides of the air outlet pipe 300, avoiding mutual interference between the air guide pipe 200 and the electrolytic cell 2, and improving the convenience of the layout of the air guide pipe 200.

[0052] For example, the upper wall of the air outlet pipe 300 is provided with a protrusion protruding upward, and the air outlet 310 penetrates the protrusion of the upper wall of the air outlet pipe 300. In addition, the lower wall of the air outlet pipe 300 is provided with a protrusion protruding downward, and the air inlet 320 penetrates the protrusion of the lower wall of the air outlet pipe 300, and the air guide pipe 200 is connected with the lower wall of the air outlet pipe 300.

[0053] As shown in Figure 1 , the distance between the upper wall of the air outlet pipe 300 and the tank shell of the electrolytic cell 2 is 9mm-12mm. That is, the distance between the air outlet 310 and the tank shell of the electrolytic cell 2 is 9mm-12mm. For example, the distance between the protrusion of the upper wall of the air outlet pipe 300 and the tank shell of the electrolytic cell 2 is 9mm-12mm.

[0054] For example, the distance between the protrusion of the upper wall of the air outlet pipe 300 and the tank shell of the electrolytic cell 2 is 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, and the distance between the air outlet 310 and the tank shell of the electrolytic cell 2 is 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm.

[0055] When the distance between the protrusion of the upper wall of the air outlet pipe 300 and the tank shell of the electrolytic cell 2 is less than 9mm, the air outlet of each air outlet 310 covers a small area on the tank shell of the electrolytic cell 2, the air outlet of the air outlet 310 is not fully utilized, the tank shell of the electrolytic cell 2 is prone to uneven temperature, or the density of the air outlet 310 is larger; when the distance between the protrusion of the upper wall of the air outlet pipe 300 and the tank shell of the electrolytic cell 2 is greater than 12mm, the air outlet of the air outlet 310 is lost during transmission to the tank shell of the electrolytic cell 2, the loss of compressed air increases, and energy is wasted.

[0056] When the distance between the protrusion of the upper wall of the air outlet pipe 300 and the tank shell of the electrolytic cell 2 is 9mm-12mm, the air outlet of the air outlet 310 can cover a large area on the tank shell of the electrolytic cell 2, and the loss of the air outlet of the air outlet 310 during transmission to the tank shell of the electrolytic cell 2 can be reduced.

[0057] As shown in Figure 1 , the air inlet 320 is arranged at the center of the length direction of the air outlet pipe 300, that is, the center axis of the protrusion of the lower wall of the air outlet pipe 300 and the center line of the length direction of the air outlet pipe 300 coincide. Among them, a plurality of air outlets 310 can be symmetrically arranged about the air inlet 320.

[0058] In this way, the distance between the air outlet 310 and the air inlet 320 at both ends of the air outlet pipe 300 is the same, thereby reducing the distance between each air outlet 310 and air inlet 320, ensuring that the compressed air entering the air outlet pipe 300 from the air inlet 320 can flow to each air outlet 310 more quickly, improving the uniformity of the air output of the plurality of air outlets 310, and facilitating the uniformity of the temperature of the cell wall of the electrolytic cell 2, thereby reducing the probability of damage to the electrolytic cell 2 due to a large difference in the temperature of the cell wall.

[0059] As shown in Figure 1 the compressed air pipe 100 is provided as a hard pipe, for example, the compressed air pipe 100 can be a galvanized compressed air pipe 100, an aluminum alloy compressed air pipe 100, a carbon steel seamless compressed air pipe 100, etc. In this way, the compressed air pipe 100 is easy to install, the relative position between the compressed air pipe 100 and the air source is more stable, and the relative position between the compressed air pipe 100 and the air guide pipe 200 is more stable, thereby reducing the risk of compressed air leakage.

[0060] As shown in Figure 1 the air outlet pipe 300 is provided as a hard pipe, for example, the air outlet pipe 300 can be a steel pipe, a copper pipe, a plastic pipe, etc. In this way, the air outlet pipe 300 is easy to install, the relative position between the air outlet pipe 300 and the electrolytic cell 2 is stable, the relative position between the air outlet pipe 300 and the air guide pipe 200 is stable, the air outlet pipe 300 uniformly cools the electrolytic cell 2, and can cool the preset part of the electrolytic cell 2, thereby reducing the probability of damage to the electrolytic cell 2.

[0061] As shown in Figure 1 the air guide pipe 200 includes a soft pipe section 210, and the hardness of the hard pipe is greater than the hardness of the soft pipe section 210. For example, the soft pipe section 210 can be a polyurethane foam (PUR) pipe, an ethylene propylene diene monomer (EPDM) pipe, or a plastic pipe. In this way, the soft pipe section 210 of the air guide pipe 200 is easy to deform, so that the soft pipe section 210 can adapt to different installation spaces, facilitating the connection of the air outlet pipe 300 and the compressed air pipe 100 through the air guide pipe 200, and the layout of the electrolytic cell blowing and cooling device 1 is more convenient.

[0062] As shown in Figure 1 the air guide pipe 200 further includes a hard pipe section 220, the soft pipe section 210 is connected to the compressed air pipe 100, the hard pipe section 220 is connected between the soft pipe section 210 and the air outlet pipe 300, and the hardness of the hard pipe section 220 is greater than the hardness of the soft pipe section 210. For example, the hard pipe section 220 can be a steel pipe, a copper pipe, or a plastic pipe.

[0063] The angle between the central axis of the compressed air pipe 100 and the central axis of the air outlet pipe 300 is not less than 45°. For example, the compressed air pipe 100 can extend in the vertical direction, and the air outlet pipe 300 can extend in the horizontal direction, that is, the central axis of the compressed air pipe 100 is perpendicular to the central axis of the air outlet pipe 300.

[0064] Since the hose section 210 is easy to deform, the relative angle between the hose section 210 and the compressed air pipe 100 is easy to adjust, and the relative angle between the hose section 210 and the hard pipe section 220 is also easy to adjust. The hard pipe section 220 and the air outlet pipe 300 can be connected by welding or the like to ensure the connection strength between the hard pipe section 220 and the air outlet pipe 300, and the relative position between the hard pipe section 220 and the air outlet pipe 300 is reliable, the sealing performance is better, and the risk of compressed air leakage is reduced.

[0065] As shown in Figure 1 The electrolytic tank air blowing cooling device 1 further comprises a flow meter 700, and the flow meter 700 is arranged in the air guide pipe 200. The flow meter 700 is used to measure the air flow in the air guide pipe 200.

[0066] In this way, the electrolytic tank air blowing cooling device 1 can clearly display the air flow in the air guide pipe 200, so that the operating personnel can timely understand the running state of the electrolytic tank air blowing cooling device 1. On the one hand, it can more reliably judge whether the electrolytic tank air blowing cooling device 1 is damaged and has a fault, and on the other hand, according to the data of the flow meter 700, the air amount used by the electrolytic tank 2 cooled by the electrolytic tank air blowing cooling device 1 in a preset time (one day, one month or one quarter) can be compared with the air amount used by the electrolytic tank cooled by the ground wind (i.e. without using the electrolytic tank air blowing cooling device 1) in the preset time (one day, one month or one quarter), so as to adjust the parameters of the time type switch electric appliance 500, optimize the switching interval time of the electromagnetic valve 400, and thus optimize the working performance of the electrolytic tank air blowing cooling device 1, and achieve the balance between the low temperature of the tank shell of the electrolytic tank 2, the low energy consumption, and the slow damage speed of the pipeline and the valve body.

[0067] As shown in Figure 1 The flow meter 700 is located downstream of the electromagnetic valve 400. In this way, after the electromagnetic valve 400 is closed, the compressed air in the compressed air pipe 100 will not contact the flow meter 700, so that the data of the flow meter 700 will not change after the electromagnetic valve 400 is closed, and the accuracy of the detection data of the flow meter 700 is improved.

[0068] As shown in Figure 1 The electrolytic tank air blowing cooling device 1 further comprises a controller 800 and a temperature detection member 900. The temperature detection member 900 can be a temperature sensor or a thermocouple.

[0069] The controller 800 is electrically connected with the electromagnetic valve 400 respectively, the temperature detecting piece 900 is electrically connected with the controller 800, the temperature detecting piece 900 is used for detecting the temperature of the tank bottom of the electrolytic tank 2, and the controller 800 controls whether the electromagnetic valve 400 is opened according to the electric signal of the temperature detecting piece 900 and the electric signal of the electromagnetic valve 400.

[0070] For example, the temperature detecting piece 900 can be arranged at the tank bottom of the electrolytic tank 2, the temperature detecting piece 900 is used for detecting the temperature of the tank bottom of the electrolytic tank 2, and the temperature detecting piece 900 can be arranged in a staggered manner with the gas outlet 310 in the length direction of the electrolytic tank 2, so as to avoid the influence of the gas outlet of the gas outlet 310 on the detection result of the temperature detecting piece 900, and improve the detection accuracy of the temperature detecting piece 900.

[0071] Specifically, the temperature detecting piece 900 can detect the temperature of the tank bottom of the electrolytic tank 2, and then feed back the detected temperature to the controller 800, and the controller 800 can acquire the opening and closing state of the electromagnetic valve 400. For example, as shown in Figure 3 and Figure 4 , the controller 800 can judge the opening and closing state of the electromagnetic valve 400 through the electric signal fed back by the electromagnetic valve 400, so that when the time type switching electric appliance 500 is damaged, the result of judging the opening and closing state of the electromagnetic valve 400 by the controller 800 is not affected, and the accuracy of the judgment is higher; or as shown in Figure 2 and Figure 4 , the controller 800 can be connected with the time type switching electric appliance 500, and the opening and closing state of the electromagnetic valve 400 can be judged through the electric signal fed back by the time type switching electric appliance 500, so that the number of wires between the controller 800 and the electromagnetic valve 400 is reduced, and the layout is simpler.

[0072] When the temperature fed back by the temperature detecting piece 900 is greater than the preset temperature, it indicates that the temperature of the tank shell of the electrolytic tank 2 may be high at present, if the electromagnetic valve 400 is in the closed state at this time, the tank shell of the electrolytic tank 2 cannot be cooled, and the risk of damage of the tank shell of the electrolytic tank 2 rises. As shown in Figure 3 and Figure 4 , the controller 800 can directly output a control signal to the electromagnetic valve 400 to make the electromagnetic valve 400 open, so that when the time type switching electric appliance 500 is damaged, the opening of the electromagnetic valve 400 controlled by the controller 800 is not affected, and the control reliability is higher; or as shown in Figure 2 and Figure 4 , the controller 800 can output a control signal to the time type switching electric appliance 500 to make the time type switching electric appliance 500 control the electromagnetic valve 400 to open, so that the number of wires between the controller 800 and the electromagnetic valve 400 is reduced, and the layout is simpler.

[0073] For example, the controller 800 and the time switch electrical apparatus 500 can be integrated in the same power distribution cabinet 510, and the power distribution cabinet 510 can be provided with an air switch or a circuit breaker protector and the like, which on the one hand improves the integration degree, reduces the space occupancy rate, and facilitates the layout, and on the other hand improves the control speed and improves the circuit safety.
