Description

Technical Field

[0001] This utility model relates to the field of busbar frame gas supply technology, and in particular to a busbar frame gas supply device and a busbar frame. Background Technology

[0002] Currently, busbar lifting frames in the electrolytic aluminum industry are largely automated, employing air-stop clamping busbar frames. These frames include clamping solenoid valves, whose input is always connected to the air tank, meaning the input is constantly ventilated. During busbar lifting operations, the clamping solenoid valve is closed upon receiving an electrical signal. Because its input is ventilated, if the valve core is stuck or the sealing ring is not properly sealed, air leakage can occur. When this leakage occurs, after the busbar frame releases the clamps, the air supply to the clamping cylinder is re-entered due to the leakage from the clamping solenoid valve, preventing the cylinder from fully releasing the clamping force.

[0003] During the lifting of the busbar, this abnormal clamping force causes relative slippage between the anode guide rod and the busbar frame, leading to a large-scale slippage accident. Such accidents not only cause serious production failures such as power outages and aluminum leakage in the electrolytic cell, but also pose significant safety risks. Utility Model Content

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0033] The busbar frame gas supply device provided in this embodiment of the invention, by setting a first switching valve, such as a ball valve, in the first gas supply pipeline, can control the first switching valve to be in a closed state during busbar lifting operations. Because the first switching valve is in a closed state, the input end of the clamping solenoid valve cannot be connected to the gas storage tank, thereby avoiding the gas leakage situation that occurs in related technologies due to valve core jamming or poor sealing of the sealing ring. Therefore, the busbar frame gas supply device provided in this embodiment of the invention can avoid gas leakage in the clamping solenoid valve during busbar lifting, thus preventing large-scale slippage accidents and ensuring safety during busbar lifting.

[0034] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the busbar frame air supply device and the busbar frame provided in the embodiments of this utility model.

[0035] Figure 1 This is a structural schematic diagram of a busbar frame air supply device provided in an embodiment of the present utility model. Figure 1 As shown, the busbar frame air supply device includes: a booster pump 10, an air tank 11, a clamping solenoid valve 12, a ground air intake pipe 13, a first air supply pipe 01, a clamping pipe 14, and a first switching valve 001; the input end A1 (with an interface) of the ground air intake pipe 13 is led to the ground, the output end A2 of the ground air intake pipe 13 is connected to the booster pump 10 through a connecting pipe 20, the booster pump 10 is connected to the air tank 11 through a connecting pipe 20, the air tank 11 is connected to the input end B1 of the clamping solenoid valve 12 through the first air supply pipe 01, and the output end B2 of the clamping solenoid valve 12 is connected to the input end of the clamping pipe 14; wherein, the first switching valve 001 is installed on the first air supply pipe 01.

[0036] Specifically, in this embodiment of the invention, ground air is supplied through the ground air intake pipe 13, and after passing through the booster pump 10, it flows into the air storage tank 11. The air storage tank 11 supplies air to the input end B1 of the clamping solenoid valve 12 through the first air supply pipe 01. By setting a first switching valve 001, such as a ball valve, on the first air supply pipe 01, the user can control the first switching valve 001 to close during the busbar lifting operation. When the first switching valve 001 is in the closed state, no air source is supplied to the input end of the clamping solenoid valve 12, which can prevent the clamping solenoid valve 12 from leaking air due to valve core jamming or poor sealing of the sealing ring. Thus, the clamping solenoid valve 12 will not be affected by the air source, thereby ensuring that the clamping cylinder will not open arbitrarily due to leakage of air from the clamping solenoid valve 12, achieving an absolutely safe state of the air circuit of the busbar lifting operation frame.

[0037] It should be noted that the output end B2 of the clamping solenoid valve 12 is connected to the clamping cylinder (not shown in the figure) through the clamping pipeline 14.

[0038] In related technologies, during the busbar lifting operation, the valve body of the clamping solenoid valve 12 is in a closed state. Since the input end of the clamping solenoid valve 12 is always in a venting state, if the clamping solenoid valve 12 is blocked by the valve core or the sealing ring is not sealed well, air leakage will occur. When air leakage occurs in the clamping solenoid valve 12, after the busbar frame is released from the clamp, the air in the clamping cylinder will re-enter the air source due to the air leakage in the clamping solenoid valve 12, causing the clamping cylinder to be unable to fully release the clamping force.

[0039] Compared to related technologies, this utility model embodiment provides a first switching valve 001, such as a ball valve, in the first gas supply pipeline 01. During the busbar lifting operation, the first switching valve 001 can be controlled to be in a closed state. Since the first switching valve 001 is in a closed state, the input end of the clamping solenoid valve 12 cannot be connected to the gas storage tank 11, thereby avoiding the gas leakage situation that occurs in the clamping solenoid valve 12 due to valve core jamming or poor sealing of the sealing ring in related technologies.

[0040] In addition, before the first switch valve 001 is opened, the input end of the clamping solenoid valve 12 is always in a state of no air supply. Even if the user accidentally touches the remote control used to control the clamping cylinder, the clamping cylinder cannot be opened because there is no air supply.

[0041] Therefore, the busbar frame air supply device provided in this embodiment of the present invention can avoid air leakage during the process of lifting the busbar by clamping the solenoid valve, thereby avoiding large-scale slippage accidents and ensuring safety during the process of lifting the busbar.

[0042] The busbar frame air supply device provided in this embodiment includes: a booster pump, an air tank, a clamping solenoid valve, a ground air inlet pipe, a first air supply pipe, a clamping solenoid valve, and a first switching valve. The input end of the ground air inlet pipe leads to the ground, and the output end of the ground air inlet pipe is connected to the booster pump. The booster pump is connected to the air tank, and the air tank is connected to the input end of the clamping solenoid valve through the first air supply pipe. The output end of the clamping solenoid valve is connected to the input end of the clamping solenoid valve. The first switching valve is located on the first air supply pipe. By setting the first switching valve, such as a ball valve, in the first air supply pipe, the first switching valve can be controlled to be in a closed state during the busbar lifting operation. Since the first switching valve is in a closed state, the input end of the clamping solenoid valve cannot be connected to the air tank, thereby avoiding the air leakage situation that occurs in related technologies due to valve core jamming or poor sealing of the sealing ring. Therefore, the busbar frame air supply device provided in this embodiment of the present invention can avoid air leakage during the process of lifting the busbar by clamping the solenoid valve, thereby avoiding large-scale slippage accidents and ensuring safety during the process of lifting the busbar.

[0043] In some embodiments, such as Figure 1 As shown, the busbar frame gas supply device also includes:

[0044] The exhaust valve 15 is installed on the first air supply line 01, and the exhaust valve 15 is located between the first switch valve 001 and the clamping solenoid valve 12.

[0045] Specifically, by setting an exhaust valve 15 on the first air supply line 01, and the exhaust valve 15 being located between the first switch valve 001 and the clamping solenoid valve 12, the pressure in the pipeline between the clamping solenoid valve 12 and the first switch valve 001 is released, which is beneficial to manually supply air to the clamping solenoid valve 12 after the user operates the first switch valve 001.

[0046] In some embodiments, continue as follows Figure 1 As shown, the busbar frame gas supply device also includes:

[0047] The second air supply line 02 has an output end C2 connected to the clamping and holding line 14, and an input end C1 (with an interface) for connecting to an air source; a second switch valve 002 is provided on the second air supply line 02.

[0048] Specifically, when there is no power input to the busbar frame, it cannot provide an electrical signal to the clamping solenoid valve 12, and the clamping solenoid valve 12 cannot be opened, thus preventing the supply of air to the clamping pipeline 14 through the clamping solenoid valve 12.

[0049] Based on this, this embodiment of the invention provides a second air supply line 02, which serves as an emergency air supply line for the clamping and holding line 14. When there is no power input to the busbar frame, the input end C1 of the second air supply line 02 is connected to an air source, allowing air to be supplied to the clamping and holding line 14. Furthermore, by providing a second switching valve 002, such as a ball valve, on the second air supply line 02, the air flow status of the second air supply line 02 can be controlled.

[0050] In some embodiments, Figure 2 A schematic diagram of another busbar frame air supply device provided in an embodiment of this utility model. (See diagram below.) Figure 2 As shown, the busbar frame gas supply device also includes:

[0051] The system includes an ascending solenoid valve 16, a descending solenoid valve 17, an ascending pipeline 18, and a descending pipeline 19; the gas storage tank 11 comprises two tanks.

[0052] One gas storage tank 11 is connected to the input terminal F1 of the lifting solenoid valve 16 and the input terminal N1 of the lowering solenoid valve 17 respectively; another gas storage tank 11 is connected to the input terminal B1 of the clamping solenoid valve 12 through the first gas supply line 01.

[0053] The output terminal F2 of the lifting solenoid valve 16 is connected to the input terminal of the rising pipe 18, and the output terminal N2 of the lowering solenoid valve 17 is connected to the input terminal of the lowering pipe 19.

[0054] Specifically, an air tank 11 is connected to the input terminal F1 of the lifting solenoid valve 16 and the input terminal N1 of the lowering solenoid valve 17. Both the rising pipeline 18 and the lowering pipeline 19 are connected to the lifting cylinder (not shown in the figure). When the lifting cylinder needs to be raised, the valve body of the lifting solenoid valve 16 is opened, and the air tank 11 supplies air to the rising pipeline 18 through the lifting solenoid valve 16, thereby raising the lifting cylinder. When the lifting cylinder needs to be lowered, the valve body of the lowering solenoid valve 17 is opened, and the air tank 11 supplies air to the lowering pipeline 19 through the lowering solenoid valve 17, thereby lowering the lifting cylinder.

[0055] Specifically, another gas storage tank 11 is connected to the input end B1 of the clamping solenoid valve 12 via the first gas supply line 01, so that the other gas storage tank 11 can supply gas to the clamping solenoid valve 12 through the clamping solenoid valve 12.

[0056] Therefore, in this embodiment of the utility model, an air storage tank 11 is provided for the rising pipe 18 and the falling pipe 19, and an air storage tank 11 is provided for the clamping and holding pipe 14, which is beneficial to the layout of the pipes.

[0057] In some embodiments, a gas storage tank 11 may be provided, through which gas is supplied to the rising pipeline 18, the descending pipeline 19 and the clamping pipeline 14 respectively. This embodiment of the present invention does not specifically limit this.

[0058] In some embodiments, such as Figure 2 As shown, the busbar frame gas supply device also includes:

[0059] The third gas supply line 03 has an output end D2 connected to the riser line 18 and an input end D1 (with an interface) for connecting to a gas source. The third gas supply line 03 is equipped with a third switch valve 003.

[0060] Specifically, when there is no power input to the busbar frame, it cannot provide an electrical signal to the lifting solenoid valve 16, so the lifting solenoid valve 16 cannot be opened, and thus cannot provide air supply to the rising pipeline 18 through the lifting solenoid valve 16.

[0061] Based on this, this embodiment of the invention includes a third gas supply line 03, which serves as an emergency gas supply line for the riser line 18. When there is no power input to the busbar frame, the input terminal D1 of the third gas supply line 03 is connected to a gas source, allowing gas to be supplied to the riser line 18. Furthermore, by installing a third switching valve 003, such as a ball valve, on the third gas supply line 03, the gas flow status of the third gas supply line 03 can be controlled.

[0062] In some embodiments, continue as follows Figure 2 As shown, the busbar frame gas supply device also includes:

[0063] The fourth gas supply line 04 has an output end E2 connected to the downcomer line 19 and an input end E1 (with an interface) for connecting to a gas source. The fourth gas supply line 04 is equipped with a fourth switch valve 004.

[0064] Specifically, when there is no power input to the busbar frame, it cannot provide an electrical signal to the lifting solenoid valve 16, so the lifting solenoid valve 16 cannot be opened, and thus cannot provide air supply to the rising pipeline 18 through the lifting solenoid valve 16.

[0065] Based on this, this embodiment of the invention provides a fourth gas supply line 04, which serves as an emergency gas supply line for the downcomer line 19. When there is no power input to the busbar frame, the input terminal E1 of the fourth gas supply line 04 is connected to a gas source, allowing gas to be supplied to the downcomer line 19. Furthermore, by providing a fourth switching valve 004, such as a ball valve, on the fourth gas supply line 04, the gas flow status of the third gas supply line 03 can be controlled.

[0066] In some embodiments, continue as follows Figure 2As shown, the booster pump 10 includes multiple pumps; the input end of each booster pump 10 is connected to the output end A2 of the ground air intake pipe 13 through the connecting pipe 20, and the output end of each booster pump 10 is connected to the input end of the air storage tank 11 through the connecting pipe 20. Figure 2 Two booster pumps 10 are shown as an example.

[0067] Specifically, by setting multiple booster pumps 10 to work in parallel, more gas can be delivered in the same amount of time, increasing the gas flow rate and meeting the demand for large flow rates. Furthermore, some booster pumps 10 can be turned on or off according to actual needs, flexibly adjusting the gas pressure and flow rate. Additionally, if one booster pump 10 fails, the others can continue to operate.

[0068] Based on the above embodiments, this utility model also provides a busbar frame, including the busbar frame air supply device as described in the above embodiments, and thus has the same or similar beneficial effects, which will not be repeated here.
