Description

Technical Field

[0001] The utility model relates to the field of electrolytic cells, in particular to a deformable steel grating device for an electrolytic cell. Background Art

[0002] The application scope of electrolytic cells is very wide, including metallurgical industry, chemical industry, electronics industry, synthetic materials industry, wastewater treatment engineering, food industry and environmental protection engineering. For example, in the metallurgical industry, electrolytic cells are used for the refining and manufacturing of non-ferrous metals such as aluminum, copper, zinc, nickel and lead; in the chemical industry, it is used to manufacture chlor-alkali chemical products, sodium hydroxide, aluminum oxide, etc.; in the electronics industry, electrolytic cells are used to manufacture electrolytic capacitors and semiconductor materials; in the daily operation of the electrolytic cell, combustion or penetration may occur, resulting in the loss of aluminum liquid or other electrolytes from the cell, which is generally called electrolytic cell furnace leakage. The occurrence of electrolytic cell furnace leakage will not only cause waste of resources, but also have a serious impact on production stability; when the electrolytic cell has abnormalities such as leakage, it is necessary to quickly open the grid plate at the accident location, and use an emergency shovel at the open grid plate to protect the busbar, so as to protect the busbar from damage in time and avoid damage to a wider range of equipment.

[0003] Based on the above situation, steel gratings are usually laid on the operating surface of the electrolytic cell to ensure that after an abnormality such as a furnace leak occurs, the accident location can be quickly opened through the steel grating to protect the busbar in time. However, after long-term use, the steel gratings laid on the operating surface of the electrolytic cell will be deformed to varying degrees due to magnetic fields, high-temperature materials, and daily irregular operations, causing the edges of the steel gratings and the operating surface of the electrolytic cell to be unable to adapt, resulting in the steel gratings being stuck and unable to be opened smoothly when an unsafe accident occurs and the accident rescue work is delayed.

[0004] To solve this problem, the existing technology generally upgrades the material of the steel grating itself to make it less prone to deformation. However, it still cannot completely solve the deformation of the steel grating caused by high temperature or improper operation. This deformation causes the edge of the steel grating to be easily stuck on the edge of the electrolytic cell, so that there is still a high probability that the steel grating cannot be opened in time during emergency treatment; the two sides of the steel grating of the existing technology and the edge of the electrolytic cell, or between the steel grating and the adjacent steel grating, also have the situation that the steel grating cannot be opened after deformation; in addition, if the deformed steel grating needs to be opened, it must be opened with the help of external tools and equipment, which is time-consuming and labor-intensive, and delays the efficiency of emergency treatment. Utility Model Content

[0005] In view of the above problems, a deformable steel grating device for an electrolytic cell is provided, which solves the problem that the steel grating cannot be opened after being deformed by adding components that can be deformed and a structure that can offset the deformation through displacement.

[0006] In order to solve the problems of the prior art, the utility model provides a deformable steel grating device for an electrolytic cell, comprising a main steel plate, wherein the main steel plate is designed as two pieces, one side of which is equipped with a rigid hinge for connecting to an operating surface of the electrolytic cell; and a deformation assembly, wherein the deformation assembly comprises a sliding beam, and an intermediate ridge beam is symmetrically installed on the top and bottom of the sliding beam; arc-shaped steel coils are respectively installed on both sides of the intermediate ridge beam, and one end of the arc-shaped steel coil is connected to one side of the main steel plate; two main steel plates are installed on both sides of the intermediate ridge beam, and the two main steel plates form an elastic structure through the arc-shaped steel coils and the intermediate ridge beam.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model sets two separate main steel plates and connects the two main steel plates through arc-shaped steel coils. After the steel grating structure is deformed by heat or external force, the deformation can be offset through the adaptability of the structure and material of the arc-shaped steel coils, so that the steel grating can continue to adapt to the edge of the electrolytic cell without affecting its sealing effect while ensuring that it can be opened smoothly.

[0014] 2. The utility model adds side sealing plates and side connecting plates on both sides and connects the two by spherical rollers, so that the two sides of the steel grating can offset a certain degree of deformation through displacement, so that the steel grating will not be blocked by the edge of the electrolytic cell or other steel grating edges due to deformation and get stuck.

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-Figure 7 As shown, a deformable steel grating device for an electrolytic cell includes a main steel plate 1, which is designed as two pieces, one side of which is equipped with a rigid hinge for connecting to the operating surface of the electrolytic cell, and also includes a deformation component 2, which includes a sliding beam 21, and a middle ridgeline 22 is symmetrically installed on the top and bottom of the sliding beam 21, and arc-shaped steel coils 23 are respectively installed on both sides of the middle ridgeline 22, one end of the arc-shaped steel coil 23 is connected to one side of the main steel plate 1, and two main steel plates 1 are installed on both sides of the middle ridgeline 22, and the two main steel plates 1 form an elastic structure through the arc-shaped steel coil 23 and the middle ridgeline 22.

[0026] The two main steel plates 1 can be designed to be installed symmetrically, or they can be designed to be asymmetrical in size according to actual needs, but their basic structure must remain consistent; the arc-shaped steel coil 23 is made of thinner steel sheet material, has good ductility, and can be deformed to a certain extent after being acted upon by external force. When the two main steel plates 1 are deformed and displaced by heat or by external force, they can still remain as a whole after the position change is achieved through the arc-shaped steel coil 23. The middle ridgeline 22 is fixedly connected to the sliding crossbeam 21, and the middle ridgeline 22 is symmetrically installed about the sliding crossbeam 21. The middle ridgeline 22 is installed in the middle position of the two main steel plates 1. When the two main steel plates 1 are affected by external force or high temperature and their positions change, they are displaced relative to the middle ridgeline 22.

[0027] like Figure 1 , Figure 3-Figure 6 As shown, a slot 12 is provided on one side of the surface of the main steel plate 1, and the slot 12 is adapted to one end of a sliding beam 21. A cylindrical roller 24 is provided inside the sliding beam 21, and a rotational connection is formed between the cylindrical roller 24 and the sliding beam 21. The sliding beam 21 forms a sliding connection with the inner wall of the slot 12 through the cylindrical roller 24.

[0028] The slot 12 of the main steel plate 1 has a certain depth. When the main steel plate 1 is displaced, it forms a relative movement with the sliding beam 21 through the slot 12. The cylindrical roller 24 arranged in the sliding beam 21 can reduce the friction between the sliding beam 21 and the main steel plate 1, so that the sliding beam 21 can easily form a sliding connection with the main steel plate 1.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, mounting grooves 25 are respectively provided on both sides of the middle ridge beam 22, and a winding rod is provided inside the mounting groove 25. One end of the arc-shaped steel coil 23 is fixedly connected to the winding rod in the mounting groove 25, and the arc-shaped steel coil 23 is wound around the winding rod for several turns.

[0030] The arc-shaped steel coil 23 is relatively loosely wound on the winding rod to ensure that there is enough reserved space when it is pulled by force; the material of the arc-shaped steel coil 23 itself also has corresponding ductility and can cope with the pulling or squeezing of a certain external force; at the same time, the arc structure of the arc-shaped steel plate can also offset part of the external force through deformation; the arc-shaped steel coil 23 can also be replaced by other materials, such as carbon fiber material with good ductility and high temperature resistance. The melting point of carbon fiber is very high, theoretically reaching 2600°C, and it has good high temperature resistance. At the same time, the ductility of carbon fiber can be improved by doping trace metals such as palladium in the carbon fiber material and changing the fiber structure. These improvements make the structure of the carbon fiber looser and improve its tensile capacity.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, side connecting plates 13 are welded on both sides of the main steel plate 1, and the main steel plate 1 is connected to a side sliding assembly 3 through the side connecting plates 13. The side sliding assembly includes a side sealing plate 31, and a docking track 32 is provided on one side of the side sealing plate 31. A spherical roller 33 is provided on the inner wall of the docking track 32. The side sealing plate 31 forms a sliding connection with the side connecting plate 13 through the spherical roller 33.

[0032] This structure can help the two sides of the device to undergo corresponding displacement to cope with the situation where the two sides are deformed when heated or affected by external forces, causing the two sides to be stuck with the edge of the electrolytic cell and unable to open; in this structure, the spherical roller 33 can reduce the friction between the side connecting plate 13 and the side sealing plate 31, and the number of spherical rollers 33 can be configured according to actual conditions. At the same time, the inner walls of the spherical rollers 33 and the docking track 32 can be injected with high-temperature resistant lubricating fluid to ensure their normal operation.

[0033] like Figure 2 and Figure 4 As shown, one end of the side sealing plate 31 is connected to a folded steel sheet 34 , and the side sealing plate 31 is connected to the other side sealing plate 31 through the folded steel sheet 34 .

[0034] The function of the folded steel sheet 34 is to seal and connect, to seal the gap between the two side sealing plates 31, and at the same time connect the two side sealing plates 31 so that they will not be disconnected; the folded steel sheet 34 can be made of thin steel plate, and metal welding with strong deformation ability is used at its folded position, or the folded part is connected by micro hinges, so that when the two side sealing plates 31 are squeezed or pulled against each other, the folded steel sheet 34 can offset the deformation force and maintain a good sealing effect.

[0035] like Figure 3 and Figure 4As shown, the deformable steel grating device also includes an adjusting handle 4, which includes a handle main rod 41. Both ends of the handle main rod 41 pass through a mounting seat 42 installed on the surface of the main steel plate 1. Both ends of the handle main rod 41 are respectively provided with threads 43, and the two ends of the handle main rod 41 are respectively connected to the mounting seat 42 through two adjusting nuts 44.

[0036] The function of the adjustable handle 4 is divided into two aspects. On the one hand, it can provide a handle that can quickly open the steel grating when the electrolytic cell needs to be opened; on the other hand, when the two main steel plates 1 undergo a large deformation, the steel grating cannot be opened. The fit between the adjusting nut 44 and the mounting seat 42 can be adjusted to change the distance between the two main steel plates 1, so that the device can be adapted to the edge of the electrolytic cell and can be opened smoothly.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
