[0025] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the related art, the following will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0026] When electrolysis is performed in the electrolytic cell body, a large amount of flue gas is generated. The flue gas in the electrolytic cell body is recovered by a draft fan to generate negative pressure to discharge the flue gas in the electrolytic cell body. A flue for discharging flue gas and a valve arranged on the flue are arranged on each electrolytic cell body. In order to ensure the air pressure balance in the electrolytic cell body, the worker needs to manually adjust the opening degree of the valve according to the air pressure gauge on the electrolytic cell body, so as to control the discharge amount of flue gas in the electrolytic cell body. In the related art, the worker has the risk of electric shock when adjusting the valve, and in addition, the worker needs to stand on the frame of the electrolytic cell body to adjust the valve, which is also prone to falling accidents.

[0027] In view of the above situation, please refer to Figure 1 The present application provides a valve adjusting device 1 for opening and closing the valve (not shown in the figure) on the electrolytic cell body. The worker can adjust the opening degree of the valve on the electrolytic cell body by operating the valve adjusting device 1. The greater the opening degree of the valve, the more flue gas is discharged from the electrolytic cell in a certain period of time. The opening degree of the valve refers to the position of the valve core (or valve plate) when the valve core (or valve plate) changes the flow passage throttling area during adjustment. It is usually expressed by percentage. When the valve is in the closed state, the opening degree is 0%. When the valve is in the fully open state, the opening degree is 100%.

[0028] The valve adjusting device 1 comprises a main body 10, an insulating part 20 and a sleeve part 30. The insulating part 20 is arranged on the main body 10. The sleeve part 30 is connected with the end of the main body 10, and the sleeve part 30 is used for sleeving the valve on the electrolytic cell body.

[0029] Specifically, the worker can drive the movement of the sleeve piece 30 by operating the main body 10, so that the sleeve piece 30 adjusts the valve opening. In the embodiment of the application, the specific setting position of the insulating piece 20 is not limited, for example, the insulating piece 20 can be located between the main body 10 and the sleeve piece 30; or for example, the insulating piece 20 can be located on the side of the main body 10 away from the sleeve piece 30, so that when the worker adjusts the valve, the insulating piece 20 can isolate the valve from the worker, avoiding the human body from contacting the current on the electrolytic tank body, thereby reducing the risk of electric shock accidents. After the sleeve piece 30 is sleeved on the valve, the valve adjusting device 1 can make the valve move or rotate through the sleeve piece 30, which is not limited here.

[0030] It should be noted that, by setting the insulating piece 20 and the sleeve piece 30 on the main body 10, the sleeve piece 30 can be sleeved on the valve of the electrolytic tank body, and the worker does not need to directly contact the valve on the electrolytic tank body, and the insulating piece 20 can isolate the valve on the electrolytic tank body from the human body, that is, isolate the electrolytic tank body from the ground, to avoid electric shock accidents caused by the current flowing through the human body from the electrolytic tank body to the ground. That is, by setting a valve adjusting device 1 for the electrolytic tank body, the risk of electric shock accidents of the worker when adjusting the valve of the electrolytic tank body can be effectively reduced.

[0031] Further, in some embodiments of the application, the insulating piece 20 includes an insulating hard plastic rod to improve the strength of the insulating piece 20 and prolong the service life of the valve adjusting device 1.

[0032] Please continue to see Figure 1 In some embodiments of the application, the main body 10 and the insulating piece 20 extend along the first direction L1, at this time the sleeve piece 30 can be arranged at the end of the main body 10 along the first direction L1, and the main body 10, the insulating piece 20 and the sleeve piece 30 are arranged in the same direction, so as to facilitate the transmission of force on the valve adjusting device 1, that is, to facilitate the operation and use of the worker.

[0033] In the embodiment, the length of the main body 10 and the insulating piece 20 along the first direction L1 can be set to facilitate the worker to control the opening of the valve only by using the valve adjusting device 1. The size of the main body 10 and the insulating piece 20 is not limited in the embodiment of the application, for example, the length of the main body 10 can range from 50 cm to 100 cm, and the length of the insulating piece 20 can range from 30 cm to 70 cm. The diameter (or width) of the sleeve piece 30 can be selected according to the specific size of the valve, for example, the diameter of the sleeve piece 30 can be 24 mm, and at this time the diameter of the main body 10 and the insulating piece 20 can be 20 mm.

[0034] Please continue to see Figure 1 In some embodiments of the present application, the main body 10 comprises a connecting part 11, which is located between the sleeve part 30 and the insulating part 20, and is fixedly connected with the sleeve part 30 and the insulating part 20. The sleeve part 30 is used to sleeve with the valve on the electrolytic tank body, and the opening degree of the valve is adjusted through the sleeve part 30. The sleeve part 30 has a force on the valve, that is, the sleeve part 30 also has a force between the sleeve part 30 and the connecting part 11. In order to ensure the connecting strength of the connecting part 11 and the sleeve part 30, the connecting part 11 and the sleeve part 30 can be made of metal material.

[0035] Further, the connecting part 11 comprises a metal rod, which can improve the strength of the main body 10 and prevent the sleeve part 30 from loosening when controlling the valve. For example, the connecting part 11 comprises a steel pipe. The connecting part 11 can be specifically set as a telescopic metal rod, so that the length of the main body 10 can be adjusted according to the actual height of the valve, to facilitate the use and operation of the staff.

[0036] Please see Figure 1 In some embodiments of the present application, the main body 10 further comprises a handle part 12, which is located on the side of the insulating part 20 away from the connecting part 11, and is fixedly connected with the insulating part 20. The connecting part 11 needs to provide sufficient strength for the sleeve part 30 to adjust the valve, and the handle part 12 is used for the staff to hold and operate. Therefore, the handle part 12 needs to withstand external force, and the handle part 12 also needs to have sufficient strength. Further, the handle part 12 comprises a metal handle, so that the handle part 12 has sufficient strength for the staff to hold. The insulating part 20 is located between the handle part 12 and the connecting part 11, so that the handle part 12 and the connecting part 11 protect the insulating part 20.

[0037] Further, please continue to see Figure 1 In some embodiments of the present application, the handle part 12 comprises a first part 121 and a second part 122, which are vertically arranged. The first part 121 is connected with the first end of the second part 122, and the second end of the second part 122 is fixedly connected with the insulating part 20, so as to facilitate the staff to manually hold and exert force.

[0038] Wherein, the embodiment of the present application does not limit the specific connection mode between the first part 121 and the second part 122, for example, the first part 121 and the second part 122 can be fixedly connected to improve the strength of the handle part 12; for another example, the first part 121 and the second part 122 can be detachably connected to facilitate the storage and installation of the valve adjusting device 1.

[0039] Further, please continue to see Figure 1 In some embodiments of the present application, the first part 121 and the second part 122 are arranged in a T-shaped structure, so as to facilitate the worker to hold the first part 121 with both hands and apply a force in a direction perpendicular to the first part 121.

[0040] Please see Figures 1-2 In some embodiments of the present application, the sleeve joint 30 includes a sleeve 31 and a limiting part 32, the sleeve 31 is fixed with the end of the main body 10, the sleeve 31 has a first opening 311 for the valve to extend into the sleeve 31, and the limiting part 32 is arranged inside the sleeve 31 and is used to limit the valve to prevent the relative movement of the valve inside the sleeve 31. It can be understood that when the valve extends into the sleeve 31 from the first opening 311, the limiting part 32 in the sleeve 31 contacts the valve, and when the valve adjusting device 1 adjusts the valve opening through the sleeve 31, the limiting part 32 abuts against the valve, that is, the limiting part 32 and the valve generate a force between them, and the limiting part 32 drives the valve to move or rotate.

[0041] Specifically, the sleeve 31 has a containing cavity, and the limiting part 32 is arranged around the inner wall of the containing cavity, and the valve extends into the containing cavity through the first opening 311, wherein the shape of the limiting part 32 formed by surrounding is the same as the shape of the valve, for example, the shape of the limiting part 32 formed by surrounding can be a regular polygon, an ellipse or an irregular shape, and the embodiment of the present application does not make specific limitation.

[0042] Please see Figures 2-3 In some embodiments of the present application, the sleeve joint 30 further includes a guide part 33, the first end of the guide part 33 is connected with the end of the sleeve 31 away from the main body 10, and the second end of the guide part 33 is inclinedly arranged away from the sleeve 31, and the guide part 33 is used to guide the valve into the sleeve 31.

[0043] Specifically, the guide part 33 is annularly arranged at the first opening 311 of the sleeve 31, and the sleeve 31 is located in the middle part of the annular guide part 33. Since the first opening 311 on the sleeve 31 is small, the valve is not easy to pass through the first opening 311 when the staff aligns the valve using the valve adjusting device 1. In the embodiment of the present application, the side surface of the guide part 33 is obliquely arranged, that is, the guide part 33 has a guide inclined surface, and the valve can more easily slide along the guide inclined surface and enter the sleeve 31 through the first opening 311.
