Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety pressure relief equipment technology, and in particular to a safety pressure relief equipment for a busbar lifting frame. Background Technology
[0002] In the aluminum industry's electrolytic cells, the anode busbar is suspended on the electrolytic cell by an anode elevator. The guide rod of the anode carbon block is pressed against the busbar by a clamping device to fix it relative to the busbar. As the anode carbon block burns out, the anode elevator carries the anode carbon block down. When the anode elevator descends to the bottom dead center, it can no longer descend. At this time, the busbar needs to be lifted. When lifting the busbar, the anode clamping mechanism in the busbar lifting frame is used to clamp the anode carbon block so that it is close to the busbar. Then the busbar lifting begins. During the lifting process, the small box clamp needs to be loosened. After the busbar is lifted, the small box clamp needs to be tightened.
[0003] However, in existing fully automatic busbar lifting frames, during the busbar lifting process, the pipeline achieves air cut-off clamping after venting. But when a component malfunctions, gas can easily enter the pipeline, potentially causing the clamping cylinder to open. If the clamp has already loosened at this point, it can lead to a slippage accident, affecting the safe operation of the electrolytic cell. Therefore, those skilled in the art have provided a safety pressure relief device for busbar lifting frames to solve the problems mentioned in the background art. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a busbar lifting frame safety pressure relief device, which solves the problem mentioned in the background technology that when a component fails, gas can easily enter the pipeline, which can easily cause the clamping cylinder to open. If the clamp has already loosened at this time, it will lead to a sliding pole accident and affect the safe operation of the electrolytic cell.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a busbar lifting frame safety pressure relief device, comprising two sets of mounting plates, with two symmetrical sliding rods fixed between the two sets of mounting plates. A cylinder is slidably fitted onto the outer circumferential surface of each of the two sliding rods.

A bypass ball valve is fixedly and continuously connected to the bottom of the outer circumferential sidewall of the lifting rod. A block is fixedly connected to the outer top surface of the lifting rod. Pressure relief pipe one and pressure relief pipe two are fixedly fixed at the top two ends of the outer circumferential sidewall of the lifting rod, respectively. A bypass ball valve two is fixedly and continuously connected to the outer circumferential sidewall of both pressure relief pipe one and pressure relief pipe two.
[0006] As a further technical solution of this utility model, straight blocks are fixedly installed at both ends of the outer top surface of the electrolytic cell. A through square opening is opened on the outer side wall of the two straight blocks. One end of the two connecting plates is respectively inserted into the inner side of the two square openings and is threaded to the two straight blocks by positioning screws.
[0007] As a further technical solution of this utility model, the top of the outer peripheral sidewall of the two slide rods is provided with screw holes distributed in a linear array, and the two cylinders are fixed to each other by limiting screws and screw holes.
[0008] As a further technical solution of this utility model, both the first pressure relief pipe and the second pressure relief pipe are connected to the inner wall of the lifting rod.
[0009] As a further technical solution of this utility model, the movable end of the lifting rod is fixedly connected to the outer top surface of the busbar.
[0010] As a further technical solution of this utility model, the electrolytic cell has a circular barrel-shaped structure.
[0011] As a further technical solution of this utility model, both ends of the outer side walls of the two sets of mounting plates are threaded with fastening screws.
[0012] This utility model provides a safety pressure relief device for a busbar lifting frame, which has the following advantages compared with the prior art:
[0013] 1.

[0014] 2.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 This utility model provides a technical solution for a busbar lifting frame safety pressure relief device: it includes two sets of mounting plates 1, with two symmetrical sliding rods 101 fixed between the two sets of mounting plates 1. Cylindrical cylinders 102 are slidably sleeved on the outer circumferential surfaces of both sliding rods 101. L-shaped connecting plates 103 are fixedly installed at the bottom ends of the outer circumferential sidewalls of both cylinders 102. An electrolytic cell 104 is provided below the outer bottom surfaces of the two connecting plates 103. A busbar 105 is provided on the inner sidewall of the electrolytic cell 104. A lifting rod 106 is provided at the center of the outer top surface of the busbar 105. A bypass ball valve 107 is fixedly and continuously connected to the bottom of the outer peripheral sidewall. A block 108 is fixedly connected to the top surface of the lifting rod 106. Pressure relief pipe 109 and pressure relief pipe 110 are fixedly fixed at the top two ends of the outer peripheral sidewall of the lifting rod 106, respectively. A bypass ball valve 111 is fixedly and continuously connected to the outer peripheral sidewalls of both pressure relief pipe 109 and pressure relief pipe 110. Both pressure relief pipe 109 and pressure relief pipe 110 are interconnected with the inner sidewall of the lifting rod 106. The movable end of the lifting rod 106 is fixedly connected to the top surface of the busbar 105. The electrolytic cell 104 is a circular barrel structure.
[0025] In use, bypass ball valve 107 and bypass ball valve 211 are installed on the main pipeline of the lifting frame of busbar 105. After lifting and clamping busbar 105, the main air source control valve is closed. Bypass ball valve 107 and bypass ball valve 211 are kept open while lifting busbar 105. If the lifting element of busbar 105 malfunctions and leaks air when the lifting rod 106 controls the lifting of busbar 105, the air will be vented through bypass valve 1 and bypass valve 211, effectively depressurizing the lifting rod 106 and preventing air leakage from the device.
[0026] Straight blocks 2 are fixedly installed at both ends of the outer top surface of the electrolytic cell 104. A through square opening 201 is opened on the outer side wall of the two straight blocks 2. One end of the two connecting plates 103 is inserted into the inner side of the two square openings 201 respectively, and is threaded to the two straight blocks 2 by positioning screws 202. The top of the outer side wall of the two slide rods 101 is provided with screw holes 3 distributed in a linear array. The two cylinders 102 are threaded to the screw holes 3 by limiting screws 301. Fastening screws 4 are threaded to both ends of the outer side wall of the two sets of mounting plates 1. First, fix the mounting plate 1 in a suitable working position by tightening the screw 4. Then, after the connecting plate 103 moves the electrolytic cell 104 through the cylinder 102, tighten the limiting screw 301 to connect it with the screw hole 3, thereby fixing the cylinder 102 on the slide rod 101 to prevent slippage. At the same time, when disassembling and assembling the electrolytic cell 104, tighten and remove the positioning screw 202, and then let the connecting plate 103 detach from the straight block 2. The operation is simple and convenient.
[0027] The working principle of this utility model is as follows: When in use, the mounting plate 1 is first fixed in a suitable working position by fastening screw 4. Then, the electrolytic cell 104 is threadedly fixed to the two connecting plates 103. Then, the connecting plate 103 drives the electrolytic cell 104 to move on the slide rod 101 through the cylinder 102. When it reaches a suitable position, the limiting screw 301 is turned to fix the cylinder 102 on the slide rod 101.
[0028] At the same time, bypass ball valve 107 and bypass ball valve 211 are installed on the main pipeline of the lifting frame of bus 105. After lifting bus 105 and clamping it tightly, the main air source control valve is closed, so that bypass ball valve 107 and bypass ball valve 211 remain open when lifting bus 105.
[0029] Finally, when the lifting rod 106 controls the raising and lowering of the busbar 105, if the lifting busbar 105 component malfunctions and leaks gas, it will vent through the bypass valve 1 and bypass valve 2, effectively depressurizing the lifting rod 106 and preventing gas leakage from the device.
[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
