Description

Technical Field

[0001] The utility model relates to the field of electrolytic cells in the aluminum industry, in particular to an emergency material device for fire at the bottom of an electrolytic cell. Background Art

[0002] In recent years, electrolytic cell leakage accidents have frequently occurred in the aluminum industry. The current disposal solutions mainly include using an overhead crane to lift bagged alumina powder or relying on manual handling for fire extinguishing. However, these methods have obvious disadvantages. On the one hand, the control of the fire point is not accurate enough, and the alumina powder thrown from above often cannot quickly cover the fire site, resulting in poor fire extinguishing effect; on the other hand, during the manual handling of alumina powder, personnel are very likely to be scalded by high-temperature aluminum water. In addition, when using an overhead crane for lifting and fire extinguishing, the best time for repair and rescue will be delayed due to the complicated operation. Utility Model Content

[0003] In view of the above problems, an emergency material device for fire at the bottom of an electrolytic cell is provided, comprising a storage tank for storing emergency materials, a high-pressure gas source for providing the storage tank, and a transport vehicle for transporting the storage tank. A support plate is provided above the electrolytic cell, and a placement groove is provided on the support plate. The placement groove is used for placing a preset pipeline, and the preset pipeline is used to guide the emergency materials in the storage tank to the fire place.

[0004] Preferably, at least one air inlet is provided on the storage tank, and a one-way check valve is provided in the air inlet.

[0005] Preferably, the storage tank is provided with at least two discharge ports, one of which is connected to the preset pipeline through a material guiding pipeline; the other discharge ports are connected to a nozzle for manual holding through a material guiding pipeline, the material guiding pipeline is made of flexible high-temperature resistant material, and the contact between the nozzle and human hands is provided with anti-scalding material.

[0006] Preferably, the support plate supporting the head and tail ends of the preset pipeline is provided with a snap-fit ​​block hinged to the placement groove.

[0007] Preferably, the preset pipeline is provided with limit blocks at both ends of the axis, and the side of the preset pipeline is provided with a derivation pipe for guiding the emergency materials in the preset pipeline to the fire site.

[0008] Preferably, a blocking block is provided at the outlet of the outlet pipe.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. Through the cleverly designed preset pipeline system, the utility model can quickly and effectively guide the emergency materials stored in the storage tank to the fire at the bottom of the electrolytic cell. This innovative design greatly reduces the risk of direct manual contact with the fire source, thereby ensuring the life safety of the operator and reducing the potential damage caused by the accident. At the same time, due to the path optimization and precise layout of the preset pipeline, the emergency materials can reach the fire point more quickly, significantly improving the efficiency of emergency treatment. Not only that, the device is also equipped with a high-pressure gas source system to provide continuous and stable power for the transportation of emergency materials. This design ensures that the emergency materials can maintain a stable flow rate during the entire transportation process, and will not affect the transportation effect due to pipeline blockage or insufficient pressure. Therefore, whether it is a large-scale or local fire, the device can quickly and effectively transport the emergency materials to the designated location, thereby ensuring the smooth progress of the fire extinguishing work. In summary, through the synergistic effect of the preset pipeline and the high-pressure gas source, the electrolytic cell bottom fire emergency material device not only improves the efficiency and safety of emergency treatment, but also provides a more reliable and safe working environment for operators.

[0011] 2. When designing the emergency material device for electrolytic cell bottom fire, we fully considered the handling requirements of different fire situations to ensure that we can effectively deal with various emergency situations. The preset pipeline is the core component, and its layout is carefully planned to cover most possible fire areas. This design enables the emergency materials to be quickly transported to the fire point through the preset pipeline when a fire accident occurs at the bottom of the electrolytic cell, so as to quickly control the fire. However, we also realize that the preset pipeline may not cover all fire areas, especially when the fire is complex and changeable. In order to make up for this deficiency, we specially designed additional outlets. This design allows the operator to manually intervene when necessary, and use the handheld nozzle to aim at the fire area that is not covered by the preset pipeline for emergency treatment. The use of the nozzle not only increases the flexibility of emergency treatment, but also makes the fire extinguishing work more accurate and efficient. Therefore, by combining the design of preset pipelines and additional discharge ports connected to the nozzle, the electrolytic cell bottom fire emergency material device can fully cover various possible fire situations and ensure the complete handling of fire accidents. Whether it is a large-scale or local fire, the device can provide an effective solution to minimize the losses caused by fire.

[0012] 3. In the design of the emergency material device for fire at the bottom of the electrolytic cell of the utility model, we cleverly combine the use of the snap-fit ​​block and the limit block to ensure the stable fixation of the preset pipe on the support plate. The design of the snap-fit ​​block takes into account the structural characteristics of the support plate. By hinged connection with the placement groove, the snap-fit ​​block can be tightly fitted on the outer wall of the preset pipe. When the preset pipe is placed on the support plate, the snap-fit ​​block can be rotated to fit closely with the support plate and tightly clamp the preset pipe, thereby effectively preventing the lateral movement of the pipe. The limit block further strengthens the stability of the preset pipe on the support plate. The limit block is set at the head and tail ends of the preset pipe, and its size is slightly larger than the opening of the placement groove, thereby ensuring the stability of the preset pipe in the radial direction. This double fixing mechanism ensures that the preset pipe always remains fixed during the working process, whether it is Facing strong fire or interference from the external environment, it can maintain its stability and reliability. In addition, we have designed multiple export pipes in the device and equipped them with blocking blocks. These export pipes are distributed in different positions of the preset pipelines and can be opened or closed according to actual needs. The design of the blocking blocks allows us to open specific export pipes through simple operations when needed, so that emergency materials can be accurately sprayed to the fire site as needed. This design not only improves the flexibility of emergency treatment, but also avoids unnecessary material loss and waste, and ensures the efficient use of emergency materials. In summary, through the stable fixation of the locking block and the limit block and the precise coordination of multiple export pipes and the blocking block, the electrolytic cell bottom fire emergency material device can accurately and stably transport emergency materials to the fire site in an emergency, achieving efficient and economical fire extinguishing effect.

[0022] 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.

[0023] Reference Figure 1-Figure 8 : An emergency material device for a fire at the bottom of an electrolytic cell includes a storage tank 2 for storing emergency materials, a high-pressure gas source for the storage tank 2, and a transport vehicle 1 for transporting the storage tank 2. A support plate 4 is provided above the electrolytic cell, and a placement groove 41 is provided on the support plate 4. The placement groove 41 is used to place a preset pipeline 3, and the preset pipeline 3 is used to guide the emergency materials in the storage tank 2 to the fire.

[0024] At present, there are problems of untimely treatment and great safety hazards in the treatment of the bottom fire of the electrolytic cell. In view of this problem, in the utility model, the emergency materials are uniformly placed in the storage tank 2. To facilitate the movement of the storage tank 2, the storage tank 2 is transported by a transport vehicle 1. A preset pipeline 3 is arranged on the top of the electrolytic cell. The preset pipeline 3 is positioned by a placement groove 41 arranged on a support plate 4 on the electrolytic cell. When the bottom fire of the electrolytic cell occurs, the transport vehicle 1 carrying the storage tank 2 containing the emergency materials is driven to the designated position, and the emergency materials in the storage tank 2 are guided to the fire place by the preset pipeline 3 for emergency treatment. In order to maintain the flow rate of the emergency materials in the whole process, a gas source is provided to continuously pump gas into the storage tank 2 during the working process, so that the interior is always in a high-pressure state, thereby ensuring the transportation efficiency of the emergency materials. Since there is no direct manual contact with the fire part, the risk of casualties is reduced, thereby improving the overall safety factor. .

[0025] Reference Figure 2 : The storage tank 2 is provided with at least one air inlet 21, and a one-way check valve is provided in the air inlet 21.

[0026] In order to ensure the air intake effect, a one-way check valve is provided at the air inlet 21, so that when the gas source fills the gas into the storage tank 2, no accident of backflow or outflow of the contents will occur.

[0027] Reference Figure 1 and Figure 2 : The storage tank 2 is provided with at least two discharge ports 22, one of which is connected to the preset pipeline 3 through a material guiding pipeline; the other discharge ports 22 are connected to a nozzle for manual holding through a material guiding pipeline, and the material guiding pipeline is made of flexible high-temperature resistant material, and the nozzle is provided with anti-scalding material at the contact point with human hands.

[0028] The preset pipeline 3 can spray emergency materials directly onto the fire. In addition, the emergency materials can also be sprayed out from the nozzle held by the worker through the material guide pipeline. There are at least two discharge ports 22. The purpose of the setting is: when the storage tank 2 is connected to the preset pipeline 3 through a discharge port 22 and sprays emergency materials to deal with most fire accidents, if there are still some areas where the fire cannot be extinguished because the preset pipeline 3 cannot cover them, manual intervention is adopted to allow workers to use nozzles connected to other discharge ports 22 to aim at these positions and spray emergency materials to these positions, thereby ensuring that the fire accident is completely handled.

[0029] Reference Figure 3-Figure 5 A clamping block 42 hinged to the placement groove 41 is provided on the support plate 4 supporting the head and tail ends of the preset pipeline 3.

[0030] Since the preset pipe 3 is relatively long, in order to ensure that the preset pipe 3 will not be offset, a locking block 42 is provided on the placement groove 41 of the head and tail support plates 4 supporting the preset pipe 3. One side of the locking block 42 is hinged to the placement groove 41. When the preset pipe 3 is located in the placement groove 41, the locking block 42 is rotated. The locking block 42 is in contact with the support plate 4 and also with the outer wall of the preset pipe 3, thereby achieving the effect of limiting the preset pipe 3.

[0031] Reference Figure 3-Figure 8 The preset pipeline 3 is provided with limit blocks 31 at both ends of the axis, and the side of the preset pipeline 3 is provided with an outlet pipe 32 for guiding the emergency materials in the preset pipeline 3 to the fire site.

[0032] Although the preset pipe 3 has been limited by the locking block 42, there is still the possibility of radial movement in the placement groove 41 on the support plate 4. In order to limit the movement in this direction, limit blocks 31 are provided at both ends of the preset pipe 3. The size of the limit block 31 is slightly larger than the opening of the placement groove 41, ensuring that the radial movement of the preset pipe 3 in the placement groove 41 can be firmly limited. The locking block 42 first performs a preliminary limit on the preset pipe 3, and then the limit block 31 further ensures the stability of the preset pipe 3 in the radial direction to prevent it from moving, thereby ensuring that the preset pipe 3 always remains in a fixed state during operation.

[0033] Reference Figure 7 and Figure 8 : A blocking block 33 is provided at the outlet of the outlet pipe 32.

[0034] Since the position of the leakage furnace of the electrolytic cell is uncertain, a plurality of outlet pipes 32 are also provided on the preset pipeline 3. In order to avoid that emergency materials are sprayed out of all outlets at the same time, causing unnecessary material loss and waste, a blocking block 33 is provided at the outlet of each outlet pipe 32. The blocking block 33 can be made of a material that is resistant to stretching but not resistant to impact. The blocking block 33 is fixedly connected to the outlet of the outlet pipe 32 by welding or the like. When a fire accident is found at the bottom of the electrolytic cell, the blocking block 33 at the corresponding position can be knocked to break the blocking block 33, so that the outlet pipe 32 is changed from a closed state to an open state, and then the emergency material can be sprayed on the fire through the outlet pipe 32.

[0035] 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.
