[0034] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.

[0035] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] In the description of this application, "multiple" means two or more.

[0037] The aluminum electrolysis feeding system 1 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0038] like Figures 1-4 As shown, the aluminum electrolysis feeding system 1 according to an embodiment of this application includes a main blower 100, a pneumatic lifting device 200, a chute 300, and a chute air duct 400. The main blower 100 can be a Roots blower.

[0039] The pneumatic lifting device 200 is equipped with an air inlet 210, an air outlet 220, and a feed inlet 230, which are interconnected. The air inlet 210 is connected to the main blower 100 via a lifting air supply duct 500. The chute 300 is connected to the feed inlet 230, and the chute air duct 400 is connected to the air outlet 220. The chute air duct 400 is used to spray air into the chute 300. The air spray from the chute air duct 400 can drive the material on the chute 300 to move towards the pneumatic lifting device 200. When the chute air duct 400 stops spraying air, the material on the chute 300 stops moving towards the pneumatic lifting device 200.

[0040] Since the air inlet 210 of the pneumatic lifting device 200 is connected to the main fan 100 through the lifting air supply duct 500, and the air outlet 220 of the pneumatic lifting device 200 is connected to the chute air duct 400, the main fan 100, the lifting air supply duct 500, the pneumatic lifting device 200 and the chute air duct 400 are connected in series.

[0041] In addition, both the pneumatic lifting device 200 and the chute air passage 400 are supplied with air by the main blower 100. When the main blower 100 unexpectedly stops, there will be no airflow in both the pneumatic lifting device 200 and the chute air passage 400. The material in the pneumatic lifting device 200 will not be conveyed outward, and the chute 300 will also stop conveying material to the pneumatic lifting device 200, thus avoiding the accumulation of material in the pneumatic lifting device 200.

[0042] In addition, since the pneumatic conveying device 200 and the chute air channel 400 are connected in series, and the pneumatic conveying device 200 is located downstream of the chute air channel 400, the chute air channel 400 stops blowing air earlier than the pneumatic conveying device 200, that is, the chute 300 stops conveying material to the pneumatic conveying device 200 first, and then the material in the pneumatic conveying device 200 stops conveying outward, which can more reliably ensure that the pneumatic conveying device 200 does not have the problem of material accumulation, improve the speed of handling abnormal situations, and be beneficial to ensuring the feeding efficiency of the aluminum electrolysis feeding system 1.

[0043] In some embodiments of the present application, as shown in Figures 1-4 The aluminum electrolysis feeding system 1 further includes a gas permeable membrane 221 arranged at the air outlet 220. In this way, the gas can flow from the air outlet 220 to the chute air channel 400 through the gas permeable membrane 221, and the gas permeable membrane 221 prevents the material in the pneumatic conveying device 200 from flowing from the air outlet 220 to the chute air channel 400, thereby preventing the material in the pneumatic conveying device 200 from accidentally flowing into the chute air channel 400, and improving the utilization rate of the material.

[0044] In some embodiments of the present application, as shown in Figures 3-4 The lifting air supply channel 500 and the chute air channel 400 are located on the same side of the pneumatic conveying device 200, and the lifting air supply channel 500 is located below the chute air channel 400. In this way, the arrangement space required by the lifting air supply channel 500, the chute air channel 400, and the pneumatic conveying device 200 is small, which can improve the space utilization rate, and since the lifting air supply channel 500 and the chute air channel 400 are arranged in the up-down direction, interference between the lifting air supply channel 500 and the chute air channel 400 can be avoided.

[0045] In some embodiments of the present application, as shown in Figures 1-2 The lifting air supply channel 500 and the chute air channel 400 are located on the same side of the pneumatic conveying device 200, and the lifting air supply channel 500 is located below the chute air channel 400. In this way, the arrangement space required by the lifting air supply channel 500, the chute air channel 400, and the pneumatic conveying device 200 is small, which can improve the space utilization rate, and since the lifting air supply channel 500 and the chute air channel 400 are arranged in the up-down direction, interference between the lifting air supply channel 500 and the chute air channel 400 can be avoided.

[0046] In some embodiments of the present application, as shown in Figures 1-5As shown, the aluminum electrolysis feeding system 1 further comprises a first sensor 510, a second sensor 610 and a controller 700. The first sensor 510 is arranged at the lifting air supply channel 500, and is configured to detect the air flow of the lifting air supply channel 500. The second sensor 610 is arranged at the chute air channel 400, and is configured to detect the air flow of the chute air channel 400. The controller 700 is electrically connected with the second sensor 610, the first sensor 510 and the main air blower 100 respectively, and is configured to control the air output of the main air blower 100.

[0047] By arranging the first sensor 510, it can be determined whether the air flow in the lifting air supply channel 500 is sufficient, and the material in the chute 300 can be effectively driven to move only when the air flow in the lifting air supply channel 500 is sufficient, so as to ensure the transportation speed of the material in the chute 300. By arranging the second sensor 610, it can be determined whether the air flow in the chute air channel 400 is sufficient, and the material in the pneumatic lifting device 200 can be effectively driven to move only when the air flow in the chute air channel 400 is sufficient, so as to ensure the discharging speed of the pneumatic lifting device 200.

[0048] In addition, the controller 700 can adjust the air output of the main air blower 100 according to the feedback results of the first sensor 510 and the second sensor 610. For example, when the air flow in the lifting air supply channel 500 is insufficient or the air flow in the chute air channel 400 is insufficient, the air output of the main air blower 100 can be increased, and the air output of the main air blower 100 can be increased by increasing the power or the fan speed of the main air blower 100. When the air flow in the lifting air supply channel 500 is sufficient and the air flow in the chute air channel 400 is sufficient, the main air blower 100 can be controlled to maintain the current air output. When the air flow in the lifting air supply channel 500 is excessive or the air flow in the chute air channel 400 is excessive, the air output of the main air blower 100 can be reduced, and the air output of the main air blower 100 can be reduced by reducing the power or the fan speed of the main air blower 100.

[0049] In some embodiments of the present application, as shown in Figures 1-4 As shown, the aluminum electrolysis feeding system 1 further comprises a feeding control valve 620 arranged at the chute air channel 400, and configured to control the air flow of the chute air channel 400. When it is necessary to empty the material in the pneumatic lifting device 200, the feeding control valve 620 can be closed at this time, the chute air channel 400 stops blowing air to the chute 300, and the material in the chute 300 stops being transported to the pneumatic lifting device 200, so as to facilitate emptying the material in the pneumatic lifting device 200. The feeding control valve 620 can be a manual valve or an electric valve, and the manual valve is operated manually and the electric valve is operated by an electric signal.

[0050] Further, as shown inFigures 1-4 As shown in FIG. 1, the aluminum electrolysis feeding system 1 further comprises a lifting control valve 520, which is arranged in the lifting air supply channel 500 and is electrically connected with the feeding control valve 620. The opening degree of the lifting control valve 520 is proportional to the opening degree of the feeding control valve 620. The lifting control valve 520 can be a manual valve or an electric valve. The manual valve is operated manually, and the electric valve is operated by an electric signal.

[0051] When the feeding control valve 620 is closed, the air flow in the pneumatic lifting device 200 increases, and the moving speed of the material in the pneumatic lifting device 200 is too fast, which leads to unstable output of the material in the pneumatic lifting device 200. By associating the opening degree of the control valve with the opening degree of the feeding control valve 620, when the feeding control valve 620 is closed, the opening degree of the lifting control valve 520 is also reduced, thereby avoiding the increase of the air flow in the pneumatic lifting device 200, ensuring that the air flow in the pneumatic lifting device 200 is constant or has a small variation range, so as to stabilize the output of the material in the pneumatic lifting device 200.

[0052] In some embodiments, when the feeding control valve 620 is closed, the opening degree of the lifting control valve 520 can be unchanged, and the air output of the main air blower 100 is reduced, thereby avoiding the increase of the air flow in the pneumatic lifting device 200, ensuring that the air flow in the pneumatic lifting device 200 is constant or has a small variation range, so as to stabilize the output of the material in the pneumatic lifting device 200.

[0053] Of course, in some embodiments, when the feeding control valve 620 is closed, the opening degree of the lifting control valve 520 can be reduced, and the air output of the main air blower 100 is reduced, so as to realize the associated action among the feeding control valve 620, the lifting control valve 520 and the main air blower 100.

[0054] In some embodiments of the present application, as shown in FIG. 1, the aluminum electrolysis feeding system 1 further comprises a lifting control valve 520, which is arranged in the lifting air supply channel 500 and is electrically connected with the feeding control valve 620. The opening degree of the lifting control valve 520 is proportional to the opening degree of the feeding control valve 620. The lifting control valve 520 can be a manual valve or an electric valve. The manual valve is operated manually, and the electric valve is operated by an electric signal. Figure 1 Figure 3 Figure 5 As shown in FIG. 1, the aluminum electrolysis feeding system 1 further comprises a standby air blower 800, which is in communication with the lifting air supply channel 500 and is electrically connected with the main air blower 100. The standby air blower 800 is started when the main air blower 100 stops running. The standby air blower 800 can be a Roots blower, and the standby air blower 800 can be connected with the controller 700.

[0055] ​​In this way, when the main air blower 100 is unexpectedly stopped, the controller 700 controls the standby air blower 800 to start, and the standby air blower 800 supplies air to the air lifting device 200 and the chute air duct 400 through the lifting air supply duct 500, so as to ensure the continuous operation of the aluminum electrolysis feeding system 1, improve the production efficiency, and the standby air blower 800 is linked with the main air blower 100, that is, when the main air blower 100 is stopped, the standby air blower 800 starts, and when the main air blower 100 starts, the standby air blower 800 stops, which can not only reduce the energy consumption, but also ensure the production efficiency.

[0056] Of course, in some scenarios, if the air output of the main air blower 100 is insufficient, the main air blower 100 and the standby air blower 800 are started together to ensure sufficient air output and higher material conveying efficiency.

[0057] In some other embodiments of the present application, as shown in Figure 2 and Figure 4 The aluminum electrolysis feeding system 1 further includes a standby air blower 800 and a third sensor 820. The standby air blower 800 is in communication with the air inlet 210 through a standby air duct 810, and the third sensor 820 is in communication with the standby air blower 800. The third sensor 820 is used to detect the air flow of the air inlet 210. The standby air blower 800 can be a Roots blower, and the standby air blower 800 can be connected with the controller 700.

[0058] In this way, when the third sensor 820 detects that the air flow of the air inlet 210 is insufficient, the main air blower 100 may be unexpectedly stopped, the sealing performance of the lifting air supply duct 500 may be reduced, or the lifting air supply duct 500 may be blocked. At this time, the controller 700 controls the standby air blower 800 to start, and the standby air blower 800 supplies air to the air lifting device 200 and the chute air duct 400 through the standby air duct 810, so as to ensure the continuous operation of the aluminum electrolysis feeding system 1, improve the production efficiency, and the standby air blower 800 is linked with the main air blower 100, that is, when the main air blower 100 is stopped, the standby air blower 800 starts, and when the main air blower 100 starts, the standby air blower 800 stops, which can not only reduce the energy consumption, but also ensure the production efficiency.

[0059] Of course, in some scenarios, if the air output of the main air blower 100 is insufficient, the main air blower 100 and the standby air blower 800 are started together to ensure sufficient air output and higher material conveying efficiency.
