Abstract
Description
Technical Field
[0001] This utility model relates to the field of cobalt raw material extraction technology, specifically to a fireproof system for an extraction tank. Background Technology
[0002] Typically, after cobalt raw materials undergo reduction leaching, iron removal via sodium vanadium-iron method, magnesium removal via sodium fluoride, and impurity removal via P204, cobalt and nickel are separated using a P507 extraction tank (including an extraction section, a washing section, and a cobalt washing section). In the extraction section, the cobalt in the cobalt-nickel-sodium mixture is extracted into the extractant.
[0003] For example, Chinese utility model patent with publication number CN204779757U, entitled "A Cobalt-Nickel Separation and Purification Production Line in a Cobalt-Nickel Hydrometallurgical Process," states that P507 extractant enters a multi-stage countercurrent extraction tank through the extractant inlet. The cobalt-nickel-sodium mixture undergoes multi-stage countercurrent extraction in the extraction functional section of the multi-stage countercurrent extraction tank. The residual liquid formed after cobalt and nickel extraction is discharged from the residual liquid outlet. The organic phase enters a multi-stage countercurrent sodium washing extraction tank. The sodium washing acid undergoes multi-stage countercurrent sodium washing in the multi-stage countercurrent sodium washing extraction tank. The aqueous phase is returned to the cobalt-nickel-sodium mixture inlet for mixing. The organic phase enters a multi-stage countercurrent nickel washing extraction tank. The nickel washing solution undergoes multi-stage countercurrent cobalt-nickel exchange in the multi-stage countercurrent nickel washing extraction tank. The nickel solution is discharged from the nickel salt outlet. The organic phase enters a multi-stage countercurrent cobalt washing extraction tank. The cobalt washing acid undergoes multi-stage countercurrent cobalt washing in the multi-stage countercurrent cobalt washing extraction tank. The cobalt solution and organic phase extractant are discharged and can be recycled. The device performs integrated extraction of cobalt-nickel-sodium mixture, eliminating the need for a separate extraction line, thus saving production costs and reducing operational steps.
[0004] In the extraction process, the organic solvents added to the extraction tank and the resulting organic products are all flammable, which can easily cause fires or casualties. Therefore, it is necessary to upgrade the fire protection level of the extraction tank and the extraction workshop to prevent potential fire hazards. Utility Model Content

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] To address the technical problem of fire hazards in extraction workshops due to the lack of fire prevention devices, this invention provides a fire prevention system for extraction tanks. This system utilizes a discharge valve 220 installed on the extraction tank 400 to empty the material in the extraction tank 400 into a temporary storage tank 210 in the event of a fire, reducing combustible materials. Simultaneously, at least one foam gun 320 is installed relative to the extraction tank 400 to spray fire-extinguishing foam at the point of ignition. The foam gun 320 effectively prevents the spread of fire, achieving a fire extinguishing effect.
[0027] Please see Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the fire prevention system for an extraction tank according to one embodiment of the present invention. The fire prevention system for the extraction tank is configured in a connecting factory building 100. The factory building 100 includes a second-floor platform 110, which is configured to connect at least one extraction tank 400. The fire prevention system for the extraction tank includes a discharge device 200 and a fire extinguishing device 300. The discharge device 200 includes a temporary storage tank 210 and at least one discharge valve 220. The temporary storage tank 210 is spaced apart from the factory building 100, and the interior of the temporary storage tank 210 is connected to the interior of the extraction tank 400 via the discharge valve 220. The fire extinguishing device 300 includes a foam storage tank 310 and at least one foam gun 320. The foam storage tank 310 is connected to the second-floor platform 110, and the foam gun 320 is positioned opposite the extraction tank 400 and connected to the second-floor platform 110. The foam gun 320 is connected to the interior of the foam storage tank 310.
[0028] Compared to existing technologies, this device, by installing a discharge valve 220 on the extraction tank 400, can empty the material in the extraction tank 400 into the temporary storage tank 210 in the event of a fire, reducing combustibles. At the same time, by installing at least one foam gun 320 relative to the extraction tank 400, fire-extinguishing foam can be sprayed onto the fire point in the event of a fire. The foam gun 320 can effectively prevent the spread of fire and achieve the effect of extinguishing the fire. This can solve the technical problem in existing technologies where the lack of fire prevention devices in the production workshop of the extraction process leads to fire hazards in the extraction workshop.
[0029] Furthermore, the extraction plant 100 typically has multiple extraction tanks 400 arranged side by side and spaced apart from each other. The plant 100 also has a replenishment tank, a material collection tank, and a tail liquid circulation treatment tank connected to the extraction tanks 400. You can also refer to the Chinese utility model patent with publication number CN218601299U, entitled "An Automatic Detection and Automatic Adjustment Device in the Extraction Production Process". This is a conventional setting known to those skilled in the art and will not be described in detail here.
[0030] In this embodiment, as Figure 1 , Figure 2 As shown, the plant 100 also includes multiple support columns 120, which are parallel to each other and spaced apart between the second-floor platform 110 and the extraction tank 400, and are connected to both the second-floor platform 110 and the extraction tank 400.
[0031] By using multiple support columns 120 to elevate multiple extraction tanks 400, it is easy to set up anti-leakage dikes and emergency collection systems. In the event of solvent or cobalt-containing solution leakage, it can be directly intercepted to prevent ground pollution, increase air circulation and reduce fire risk. It also facilitates the installation of pipes, valves and pump sets, while providing operating channels for tank maintenance and cleaning.
[0032] Furthermore, the support column 120 here is made of steel or ductile iron, which are common and readily available on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.
[0033] In one embodiment, please refer to Figures 1 to 3 The factory building 100 also includes multiple fireproof and heat-insulating coatings 130, which are set one-to-one with the support columns 120 and are evenly applied to the surface of the support columns 120.
[0034] By applying a fireproof and heat-insulating coating 130 to the surface of the support column 120, it is possible to effectively prevent the support column 120 from tipping over due to high temperatures generated after weathering, thereby improving safety.
[0035] Furthermore, the material of the fireproof and heat-insulating coating 130 is a fireproof coating that is commonly available and readily procurable on the market, such as inorganic heat-insulating materials (e.g., expanded vermiculite, perlite), containing organic resins and expanding flame retardants (e.g., ammonium polyphosphate). This is a conventional setup known to those skilled in the art and will not be elaborated further here.
[0036] In one embodiment, please refer to Figure 1 , Figure 2The plant 100 also includes multiple support beams 140, which are distributed in a grid pattern and connected to each other. The multiple support beams 140 are located between the extraction tank 400 and the multiple support columns 120, and are connected to both the extraction tank 400 and the multiple support columns 120.
[0037] By setting up multiple interconnected support beams 140 in a grid pattern, stable support can be formed for multiple extraction tanks 400, thereby improving the safety of extraction production.
[0038] Furthermore, the supporting beam 140 here is made of steel or ductile iron, which are common and readily available in the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.
[0039] In one embodiment, please refer to Figure 1 The unloading device 200 also includes a firewall 230, which is located between the plant 100 and the temporary storage tank 210.
[0040] By setting up firewall 230, the fire can be effectively prevented from spreading from extraction tank 400 to temporary storage tank 210 after it starts, thus reducing losses.
[0041] Furthermore, the firewall 230 here is a common and readily available device on the market, and is a standard configuration known to those skilled in the art, so it will not be described in detail here.
[0042] In one embodiment, please refer to Figure 1 The unloading device 200 also includes at least one connecting pipe 240 and at least one pump body 250. One end of the connecting pipe 240 is connected to the bottom inner wall of the extraction tank 400. The unloading valve 220 is disposed on the connecting pipe 240. The liquid inlet end of the pump body 250 is connected to the other end of the connecting pipe 240, and the liquid outlet end is connected to the interior of the temporary storage tank 210.
[0043] The connecting pipe 240 is located at the bottom of the extraction tank 400 and is connected to the temporary storage tank 210 via the pump body 250.
[0044] Furthermore, in the event of a fire, the user can empty the raw materials in the extraction tank 400 with a single click using the pump body 250, which can effectively prevent the spread of fire. The pump body 250 is a common and readily available device on the market, such as a corrosion-resistant screw pump, which can transport materials containing solid particles (such as cobalt slag, incompletely dissolved raw materials) and highly corrosive media (such as cobalt sulfate solution, acidic leachate) to accelerate emptying. Further details will not be provided here.
[0045] In one embodiment, please refer to Figure 1The fire extinguishing device 300 also includes a delivery pipe 330, which is ring-shaped and laid around the periphery of at least one extraction tank 400 and connected to the second-floor platform 110. The delivery pipe 330 is connected to at least one foam gun 320.
[0046] The annular delivery pipe 330 can surround the extraction tank 400, so that if any ignition point on the extraction tank 400 causes a fire, the foam gun 320 can effectively extinguish the fire, thereby improving safety.
[0047] Furthermore, the infusion tubing here is a common and readily available fire-fighting pipe on the market, which is a standard installation known to those skilled in the art, and will not be described in detail here.
[0048] In one embodiment, please refer to Figure 2 The fire extinguishing device 300 also includes at least one rotating support 340 and at least one connecting hose 350. The rotating support 340 is connected to the second-floor platform 110 and to the foam gun 320. The two ends of the connecting hose 350 are respectively connected to the foam gun 320 and the delivery pipe 330.
[0049] The connecting hose 350 is used to connect the delivery pipe 330 and the foam gun 320. The rotating support 340 can support the foam gun 320 and realize multi-angle foam spraying.
[0050] Furthermore, the rotating support 340 and the connecting hose 350 are common and readily available equipment on the market. For reference, please refer to the Chinese utility model with publication number CN219721760U, entitled "A Foam Fire Extinguishing Unit". Further details will not be provided here.
[0051] In one embodiment, please refer to Figure 1 , Figure 2 The plant 100 also includes a first-floor platform 150, which is located below the second-floor platform 110 and is connected to the ground. The plane of the first-floor platform 150 extends downward to form a settling tank 160, which is positioned relative to the extraction tank 400.
[0052] By setting a settling tank 160 below the extraction tank 400, when the extraction tank 400 tilts, the flowing fire will collect in the settling tank 160, thus preventing a fire risk to the surrounding factory buildings 100.
[0053] In one embodiment, the depth of the settling tank 160 is 1 meter.
[0054] By setting up a settling tank 160 with a depth of 1M, the flowing liquid in multiple extraction tanks 400 can be effectively collected.
[0055] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:
[0056] At least one extraction tank 400 is installed on the second-floor platform 110 of the plant 100. A temporary storage tank 210 is connected to the interior of the extraction tank 400 via at least one discharge valve 220, enabling the emptying of material from the extraction tank 400. At least one foam gun 320 is positioned relative to the extraction tank 400 and connected to a foam storage tank, used to spray foam into the burning extraction tank 400 to extinguish the fire. Compared to existing technologies, by installing a discharge valve 220 on the extraction tank 400, the material in the extraction tank 400 can be emptied into the temporary storage tank 210 in the event of a fire, reducing combustibles. Simultaneously, by installing at least one foam gun 320 relative to the extraction tank 400, fire-extinguishing foam can be sprayed onto the fire point in the event of a fire. The foam gun 320 can effectively prevent the spread of fire, achieving the effect of extinguishing the fire.
[0057] In the specific working process of this utility model, when the extraction tank 400 catches fire due to an accident, the user can control the pump body 250 and the unloading tank to control the raw materials in the extraction tank 400 after the fire with one click. At the same time, the fireproof and heat-insulating coating 130 can effectively prevent the support column 120 from tipping over due to high temperature. In addition, the user can also use multiple foam guns 320 to spray and extinguish the fire in the extraction tank 400 after the fire, which can effectively extinguish the fire and reduce safety hazards.
[0058] This application, through the aforementioned system and structure, can solve the technical problem in the prior art where the lack of fire prevention devices in the production workshop of the extraction process leads to fire hazards in the extraction workshop.
[0059] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
