Description

Technical Field

[0001] The utility model relates to the field of electrolytic cells, and in particular to a warning device installed at the bottom of an electrolytic aluminum cell. Background Art

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode. Most of them use a diaphragm to separate the anode chamber from the cathode chamber. Depending on the electrolyte, they are divided into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. Optimizing the design of the electrolytic cell structure and rationally selecting electrode and diaphragm materials are the keys to improving current efficiency, reducing cell voltage, and saving energy consumption.

[0003] Patent No. CN202220203U discloses an electrolytic cell. The utility model relates to an electrolytic cell, which includes a cell body, wherein the cell body is pre-embedded with reinforcing ribs, wherein the reinforcing ribs are mesh reinforcing ribs composed of glass fiber reinforced bars with a diameter of 6-12 mm and a thread, and the mesh size is 0.05-0.5 m2. The utility model pre-embeds glass fiber reinforced bars with a diameter of 6-12 mm in the electrolytic cell body, thereby enhancing the strength of the cell body. The reinforcing ribs are mesh-shaped, and the mesh size is 0.05-0.5 m2. When the cell body is broken, it can effectively reduce the splashing of fragments and reduce the risk to workers. In order to prevent injuries to workers, the electrolytic cell is divided into two areas, the upper area and the lower area. When working at the bottom of the cell, workers need to go in and out from the bottom door. When there are operations such as adjusting electrolyte or discharging aluminum, or quenching effect on the cell, it is easy to cause hot materials to be squeezed out and splashed, flowing to the bottom of the cell and scalding workers. Therefore, in addition to damage to the cell itself, splashing of high-temperature materials is the biggest safety hazard to workers. The mesh steel bars will still pass through small materials, and the structural strength of the cell cannot improve safety during discharging operations. Therefore, a warning device is proposed to be installed at the bottom of the electrolytic aluminum cell to solve the above problems. Utility Model Content

[0004] In order to overcome the safety accidents that may occur during the discharge operation in the prior art, the utility model provides a warning device installed at the bottom of an electrolytic aluminum electrolytic cell, comprising a base, an electrolytic reaction cell fixedly mounted on the top of the base, a movable cover movably mounted on the outside of the electrolytic reaction cell, and a warning mechanism fixedly mounted on the outer wall of the movable cover;

[0005] A support column is fixedly installed on the top of the base, and a support platform is fixedly installed on the top of the support column, and an empty slot is opened inside the support platform;

[0006] An audible and visual warning light is fixedly mounted on the outer wall of the electrolytic reaction tank, and a control panel is fixedly mounted on the outer wall of the support platform.

[0007] Preferably, the warning mechanism includes an external cover shell, a linear slide rail is fixedly installed on the inner wall of the external cover shell, a slider is slidably connected to the outside of the linear slide rail, a warning slide rail is fixedly installed on the end of the slider away from the linear slide rail, and a sliding groove is provided inside the external cover shell, and the shape of the sliding groove is adapted to the warning slide rail.

[0008] The warning mechanism serves the purpose of physical barrier and cooperates with sound and light warnings to ensure the safety of underground operations in all aspects.

[0009] Preferably, an anti-dropping block is fixedly mounted on the inner wall of the outer cover, and the anti-dropping block is located at one end of the linear slide rail.

[0010] The anti-drop block is used to limit the position of the slider to prevent the warning slide from derailing from the linear slide.

[0011] Preferably, a tank marker is provided on the outer wall of the electrolytic reaction tank.

[0012] The slot marker is used to assist in matching the slot and the corresponding audible and visual warning light positions.

[0013] Preferably, a mesh grille is fixedly installed inside the support platform.

[0014] Preferably, a discharge door is hinged on the outer wall of the electrolytic reaction tank.

[0015] Preferably, the sound and light warning light is electrically connected to the control panel.

[0016] Preferably, the number of the empty slots is consistent with the number of warning mechanisms.

[0017] Every two warning mechanisms form a group and are mounted on the outer wall of the movable cover plate, and the empty slots adapted to the number of the warning mechanisms are used to provide space so that the warning mechanisms can be moved to the position below the slots.

[0018] Beneficial effects:

[0019] The beneficial effects produced by adopting the technical solution of this utility model are as follows:

[0020] (1) By installing sound and light warning lights on the outer wall of the electrolytic reaction tank below the support platform, and each light position corresponds to a tank position, the position of the tank position and the corresponding sound and light warning light can be determined by the tank position mark. When discharging or other operations are carried out above the support platform, the control panel is operated to turn on the sound and light warning light of the corresponding tank position, and the movable cover is opened and placed on the support platform. At this time, the warning mechanism extends and passes through the empty tank position to the bottom of the support platform. Under the illumination of the light, the staff under the tank can intuitively observe the warning mechanism, so as to stay away from the tank position where the current discharging operation is carried out, avoiding the risk of safety accidents caused by the dimness under the tank and the inability to see the permanent warning sign.

[0021] (2) The sound and light warning light not only reminds the workers under the tank by sound and light prompts, but also cooperates with the warning mechanism. When the warning mechanism passes through the empty tank, the warning slide will slide out of the warning mechanism under the drive of the slider and the linear slide rail. At this time, there will be a physical barrier consisting of two external covers and warning slides under a tank position, and a closed space will be temporarily formed between the support column, the outer wall of the electrolytic reaction tank and the two warning slides to prevent people under the tank from approaching the area. At the same time, the interior of the closed space can also block the splashing and dripping of high-temperature materials, so that the overflowed materials slide smoothly to the ground to avoid scalding the workers under the tank. After the discharge is completed, the movable cover and the electrolytic reaction tank are re-closed to store the warning mechanism. It can be used repeatedly and has high reliability.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] This embodiment is adopted. The specific implementation is as follows:

[0030] like Figures 1 to 4 As shown, a warning device is installed on the bottom of an electrolytic aluminum electrolytic cell. In this embodiment 1, a plurality of empty slots 8 are opened inside a support platform 7, and a mesh grille is installed on the opposite side of each two empty slots 8. The length of the support platform 7 is determined by the length of the electrolytic reaction cell 3, and therefore the number of empty slots 8 and mesh grilles is also determined by the length of the electrolytic reaction cell 3.

[0031] It should be noted that, since two warning mechanisms 5 are installed on the outer wall of each movable cover plate 4, when performing operations such as adjusting the electrolyte or aluminum production, extinguishing the effect, etc., it is necessary to first remove the cover plate and place it on the support platform 7. Therefore, the upper part of the support platform 7 can be divided into the upper slot operation, and the lower part of the support platform 7 belongs to the lower slot operation. The shape of the warning mechanism 5 can be adapted to the empty slot 8. By inserting the warning mechanism 5 upside down into the empty slot 8, the external cover 50 and the warning slide 53 can be moved to the lower slot operation area.

[0032] like Figures 1 to 4 As shown, a warning device is installed on the bottom of an electrolytic aluminum electrolytic cell. In this embodiment 2, a linear slide 51 is installed in the outer cover 50, and the warning slide 53 is connected to the linear slide 51 via a slider 52. When the movable cover 4 is closed on the electrolytic reaction cell 3, the sliding groove in the outer cover 50 is notched upward, and the warning slide 53 is stored in the inner part of the outer cover 50. When the movable cover 4 is removed during operation and the warning mechanism 5 is inserted into the empty slot 8, the sliding groove is notched downward, and the warning slide 53 extends out through the sliding groove and reaches the bottom of the support platform 7.

[0033] In addition, since two warning mechanisms 5 are installed on the outer wall of each movable cover plate 4, when the warning slide 53 is extended to the bottom of the support platform 7, a closed space will be enclosed between the two warning slides 53, the support column 2 and the outer wall of the electrolytic reaction tank 3 to act as a barrier, thereby avoiding the risk of burns or splashes caused by the workers under the tank moving during the discharging operation.

[0034] like Figures 1 to 4 As shown, a warning device is installed at the bottom of an electrolytic aluminum electrolytic cell. In this embodiment 3, a slot mark plate 31 is set on the outer wall of the electrolytic reaction cell 3. The number of the slot mark plates 31 corresponds to the movable cover plate 4 one by one, and a corresponding number of sound and light warning lights 9 are also installed on the outer wall of the electrolytic reaction cell 3 under the cell. The control panel 10 is electrically connected to each sound and light warning light 9. When a certain slot needs to perform operations such as discharging, the sound and light warning light 9 at the corresponding position can be turned on through the control panel 10 to remind the staff under the cell. The sound and light warning light 9 will provide light and sound reminders when it is running. In addition, the dynamically appearing warning slide 53 can more intuitively remind the staff under the cell, avoiding the risk of safety accidents caused by the darkness under the cell and the inability to see the warning signs.

[0035] Working principle:

[0036] By installing a warning mechanism 5 on the outer wall of the movable cover 4 and opening an empty slot 8 inside the support 7 to provide movement space for the warning mechanism 5, when performing electrolyte adjustment or aluminum production operations or extinguishing effects, the operation control panel 10 turns on the sound and light warning light 9 of the corresponding slot, and at the same time, the movable cover 4 is removed and fitted with the support 7 so that the warning mechanism 5 extends through the empty slot 8 to the area under the slot. After the warning slide 53 slides out, it combines with the length of the external cover 50 itself to form a physical barrier in two directions, so that the staff under the slot can stay away from the working range of a slot, avoiding the risk of burns caused by splashing or dripping high-temperature raw materials, thereby improving the overall safety during operation, and the safety measures are reliable and not prone to failure, with good safety.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
