Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal smelting equipment technology, and more specifically, to a horizontal fire extinguishing device for a sponge titanium reactor. Background Technology

[0002] In the production process of sponge titanium, refined magnesium and titanium tetrachloride undergo a magnesium thermal reduction reaction in the distillation workshop to produce sponge titanium. The reduction reaction of refined magnesium and titanium tetrachloride is carried out in a cylindrical reactor. After the reduction reaction is completed, the residual magnesium and magnesium chloride in the reactor are distilled off by high-temperature distillation. The distilled sponge titanium is in the shape of an "approximately cylindrical with a pointed cap" in the reactor. The reactor is stored vertically, and personnel use pneumatic picks to remove the titanium that has climbed the walls.

[0003] During the titanium stripping process, the low-valence titanium on the surface is flammable. If it is not dealt with in time, it can easily cause the entire titanium mass to burn, posing a major safety hazard and economic loss. When sponge titanium metal catches fire, the most effective method is to use argon gas to extinguish the fire in a sealed environment. When the existing reactor is stored vertically, an overhead crane is used to hoist the reactor cover with a sealing gasket to cover the reactor, and argon gas is used for fire extinguishing.

[0004] To improve the cleaning efficiency of titanium climbing on the upper wall of the reactor, the existing technology usually rotates the reactor 90° from vertical to horizontal. At this time, the reactor flange face is vertical. Since the protective cover inside the reactor protrudes from the reactor flange face, there are problems such as difficulty in positioning the reactor and difficulty in pressing the gasket when the reactor is set horizontally. In order to ensure operational safety, a timely and effective emergency fire extinguishing device for horizontal reactors has become an urgent problem to be solved. Summary of the Invention

[0005] The problem solved by this invention is that, in the prior art, because the protective cover inside the reactor protrudes from the reactor flange surface, there are problems such as difficulty in positioning and pressing the rubber gasket when horizontally removing titanium climbing the reactor wall.

[0006] This invention discloses a horizontal fire extinguishing device for a titanium sponge reactor, comprising a fire extinguishing cover, an elastic sealing structure, and several fastening connection structures. The elastic sealing structure is disposed on one side of the fire extinguishing cover, and the fastening connection structures are distributed around the circumference of the fire extinguishing cover, with the fastening connection structures located on the outer periphery of the elastic sealing structure. The fastening connection structures can fasten the fire extinguishing cover to the reactor flange on the reactor, and during fastening, the elastic sealing structure and the reactor flange cooperate to seal. On the other side of the fire extinguishing cover, a second protective cover, an argon filling pipe, and one or more lifting lugs are provided. The second protective cover is used to assemble with the first protective cover of the reactor, the lifting lugs are used to assist in lifting the fire extinguishing device, and the argon filling pipe is used to supply argon gas to the side with the elastic sealing structure during fire extinguishing.

[0007] The aforementioned fire extinguishing device has a simple structure. During hoisting, it only needs to be connected to one lifting lug to achieve the corresponding hoisting. When the fire extinguishing device is hoisted to the vicinity of the reactor flange, since the reactor flange is in a vertical state, there is no need to reverse the fire extinguishing device. The position of the second protective cover can be directly adjusted to align with the first protective cover. This is simple and convenient, effectively improving the fire extinguishing speed during the titanium removal process and enhancing the safety and economy of the titanium removal work.

[0008] Furthermore, the elastic sealing structure is a rubber gasket.

[0009] The sealing structure made of rubber has excellent elasticity and deformation capacity, which facilitates sealing with the surface of the reactor flange.

[0010] Furthermore, the fastening connection structure is a G-clamp.

[0011] The G-clamp design eliminates the need for alignment of the cylinder and hole when fastening the fire extinguishing cover to the reactor flange, allowing for direct assembly and significantly improving assembly convenience and speed.

[0012] Furthermore, a retaining ring structure is fixedly installed on the fire extinguishing cover, and the elastic sealing structure is sleeved on the outer periphery of the retaining ring structure.

[0013] The baffle structure can support the baffle structure and prevent it from undergoing radial irregular deformation under the action of the fire extinguishing cover and the reactor flange, which would affect the sealing between the fire extinguishing cover and the reactor cylinder and ensure the normal use of the fire extinguishing device.

[0014] Furthermore, the retaining ring structure includes an arc-shaped retaining block arranged in a ring shape, and the elastic sealing structure is sleeved on the outer periphery of the arc-shaped retaining block.

[0015] This setup only requires a single curved stop to accommodate the elastic sealing device.

[0016] Furthermore, the retaining ring structure includes two or more arc-shaped blocks, the outer circumferential arcs of the two or more arc-shaped blocks are on the same circle, and the elastic sealing structure is sleeved on the outer circumference of the arc-shaped blocks.

[0017] This design ensures that the elastic sealing structure is subjected to uniform force in the circumferential direction, thereby preventing irregular radial deformation when subjected to the forces of the fire extinguishing cover and the reactor flange, and ensuring the sealing performance of the fire extinguishing device.

[0018] Furthermore, the fire extinguishing cover is circular, and the elastic sealing structure and the retaining ring structure are annular structures. The diameter of the fire extinguishing cover is denoted as Φ1, the inner diameter of the retaining ring structure is denoted as Φ2, the outer diameter of the retaining ring structure is denoted as Φ3, the inner diameter of the elastic sealing structure is denoted as Φ4, and the outer diameter of the elastic sealing structure is denoted as Φ5. Then, Φ2<Φ4≤Φ3<Φ5<Φ1.

[0019] By setting Φ5<Φ1, a corresponding gap is provided at the outer edge of the fire extinguishing cover, which can be fixedly connected using G-clamps. By setting Φ2<Φ4≤Φ3<Φ5, the retaining ring structure and the elastic sealing structure are interference-fitted, thereby ensuring the installation stability of the elastic sealing structure and preventing it from falling off the retaining ring structure.

[0020] Furthermore, the thickness of the retaining ring structure is less than the compression thickness of the elastic sealing structure, wherein the compression thickness of the elastic sealing structure refers to the thickness of the elastic sealing structure after it is compressed and deformed after the fire extinguishing cover is fastened to the reactor flange.

[0021] This design prevents the retaining ring structure from coming into contact with the reactor flange during the fastening connection of the fire extinguishing cover and the reactor flange, which would prevent the elastic sealing structure from being fully compressed and deformed, resulting in poor sealing performance. This ensures the sealing performance after the fire extinguishing cover and the reactor flange are fastened together.

[0022] Furthermore, there are four lifting lugs, which are arranged in pairs near the outer edge of the fire extinguishing cover. The line connecting the geometric center of the projection of the second protective cover onto the fire extinguishing cover and the geometric center of the fire extinguishing cover is denoted as line segment M. The projection of the line connecting two of the four lifting lugs onto the fire extinguishing cover is collinear with line segment M, and the projection of the line connecting the other two lifting lugs onto the fire extinguishing cover forms a 90° angle with line segment M.

[0023] The above configuration ensures that the projection of the line connecting the two opposing lifting lugs on the fire extinguishing cover forms a cross shape. This allows the lifting lugs to be evenly distributed around the perimeter of the fire extinguishing cover near its outer edge. Consequently, during fire extinguishing, the second protective cover can be aligned and assembled with the first protective cover with only a slight rotation or without rotating the fire extinguishing cover. This significantly improves the assembly speed of the fire extinguishing device and the reactor during the climbing titanium removal process, and enhances its operational safety.

[0024] Further, there are eight lifting lugs, and the eight lifting lugs are arranged in pairs and located near the outer edge of the fire extinguishing cover plate. The two opposite lifting lugs are regarded as a group, and there are a total of four groups. The line connecting the geometric center of the projection of the second protective cover on the fire extinguishing cover plate and the geometric center of the fire extinguishing cover plate is denoted as line segment M. Among them, the projection of the connection line of the two lifting lugs in the first group on the fire extinguishing cover plate is collinear with line segment M, the projection of the connection line of the two lifting lugs in the second group on the fire extinguishing cover plate forms a 90° angle with line segment M, the projection of the connection line of the two lifting lugs in the third group on the fire extinguishing cover plate forms a 45° angle with line segment M, and the projection of the connection line of the two lifting lugs in the fourth group on the fire extinguishing cover plate forms a 135° angle with line segment M.

[0025] Through the above settings, the projections of the connection lines of the four groups of lifting lugs on the fire extinguishing cover plate are arranged in a "rice" shape, and the eight lifting lugs can be evenly arranged on the circumferential side of the fire extinguishing cover plate near the outer edge. Therefore, when extinguishing the fire, only fine-tuning or no rotation of the fire extinguishing cover plate is required to align and assemble the second protective cover with the first protective cover, significantly improving the assembly speed of the fire extinguishing device and the reactor during the wall-climbing titanium removal, and enhancing its working safety.

[0026] Compared with the prior art, the horizontal fire extinguishing device for the titanium sponge reactor of the present invention has the following advantages:

[0027] 1. Through the setting of the lifting lugs, while facilitating the lifting of the fire extinguishing device, it is convenient for the quick positioning and alignment of the first protective cover and the second protective cover, thereby improving the assembly efficiency of the fire extinguishing device and the reactor and enhancing the fire extinguishing speed;

[0028] 2. The outer diameter dimensions of the flanges of the fire extinguishing device and the reactor are the same, enabling quick alignment of the two. At the same time, G-clamps are used for locking, which can quickly form a sealed environment;

[0029] 3. Through the setting of the retaining ring structure, after the rubber pad is tensioned, it is sleeved on the outer circumference of the retaining ring, forming good support for the rubber pad, ensuring an effective compression seal between the rubber pad and the reactor flange, and solving the problem of fixing the rubber pad in the vertical state;

[0030] 4. An argon filling pipe is provided on the fire extinguishing cover plate, facilitating quick argon filling for quick fire extinguishing;

[0031] 3. The structure of the present invention is simple and easy to use. When a fire occurs during the horizontal stripping of the wall-climbing titanium of the reactor, it can be quickly assembled within 15S to form a sealed argon environment and extinguish the fire immediately.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a horizontal fire extinguishing device using a sponge titanium reactor.

[0040] Example 1

[0041] This embodiment provides a horizontal fire extinguishing device with a titanium sponge reactor, such as... Figures 1-4 As shown, the device includes a fire extinguishing cover 900, an elastic sealing structure, and several fastening connection structures. The elastic sealing structure is located on one side of the fire extinguishing cover 900. The fastening connection structures are distributed around the circumference of the fire extinguishing cover 900, with the fastening connection structures located on the outer periphery of the elastic sealing structure. The fastening connection structures can fasten the fire extinguishing cover 900 to the reactor flange 700 on the reactor, and during fastening, the elastic sealing structure and the reactor flange 700 cooperate to seal. On the other side of the fire extinguishing cover 900, a second protective cover 400, an argon filling pipe 300, and one or more lifting lugs 100 are provided. When the fire extinguishing cover 900 is fastened to the reactor flange 700, the second protective cover 400 cooperates with the first protective cover 600 of the reactor. The lifting lugs 100 are used to assist in lifting the fire extinguishing device, and the argon filling pipe 300 is used to supply argon gas to the side with the elastic sealing structure during fire extinguishing.

[0042] The second protective cover 400 can be assembled with the first protective cover 600 during assembly. This creates a sealed space between the fire extinguishing cover 900 and the reactor cylinder 800 when the elastic sealing structure seals with the reactor flange 700. In this case, if a fire breaks out during the titanium removal process, the fire extinguishing device can be hoisted to the horizontally positioned reactor, and the second protective cover 400 can be positioned in conjunction with the first protective cover 600. Then, the fire extinguishing cover 900 and the reactor flange 700 are fastened together using a fastening connection structure. During this fastening, the elastic sealing structure deforms under the action of the fire extinguishing cover 900 and the reactor flange 700, achieving a sealed assembly between them and creating a sealed space between the fire extinguishing cover 900 and the reactor cylinder 800. Argon gas is then injected into the sealed space through the argon filling pipe 300 to quickly extinguish the fire inside the reactor. The fire extinguishing device provided in this embodiment has a simple structure. During hoisting, it only needs to be connected to one lifting lug 100. When hoisting the fire extinguishing device to the vicinity of the reactor flange 700, since the reactor flange 700 is in a vertical position, there is no need to reverse the fire extinguishing device. The position of the second protective cover 400 can be directly adjusted to align with the first protective cover 600. This is simple and convenient, effectively improving the fire extinguishing speed during the titanium removal process and enhancing the safety and economy of the titanium removal work. It should be noted that the first protective cover 600 is an existing component inside the reactor, its function being to protect other components inside the reactor. This invention does not involve any improvement to the first protective cover 600; only a corresponding second protective cover 400 needs to be installed on the fire extinguishing cover 900. The specific structure of the first protective cover 600 and the position and connection relationship of the components it protects will not be elaborated further. It should be understood that the fire extinguishing cover 900 is provided with a through hole, which is connected to the argon filling pipe 300 to facilitate the delivery of argon gas. The through hole can be located at the geometric center of the fire extinguishing cover 900, or it can be located at any position inside the elastic sealing structure other than the second protective cover 400.

[0043] As an embodiment of the present invention, the elastic sealing structure is a rubber gasket 500. The sealing structure made of rubber has excellent elasticity and deformation capacity, which facilitates sealing with the surface of the reactor flange 700.

[0044] In this embodiment, the fastening connection structure is a G-clamp (not shown in the attached diagram). Existing technologies often use bolts to fasten two plates together. This method requires alignment of the bolts with the holes for assembly, resulting in slow assembly speed. However, in this embodiment, the G-clamp eliminates the need for alignment of the cylinder and hole when fastening the fire extinguishing cover 900 to the reactor flange 700, allowing for direct assembly and significantly improving assembly convenience and speed. The structure of the G-clamp can be referenced from existing technologies and will not be elaborated upon or limited here.

[0045] As one of the alternative embodiments, such as Figure 3 , Figure 4 As shown, a retaining ring structure 200 is fixedly installed on the fire extinguishing cover 900, and the elastic sealing structure is sleeved on the outer periphery of the retaining ring structure 200. The retaining ring structure 200 can support the retaining ring structure 200, preventing it from undergoing radial irregular deformation under the action of the fire extinguishing cover 900 and the reactor flange 700, thus affecting the sealing between the fire extinguishing cover 900 and the reactor cylinder 800 and ensuring the normal use of the fire extinguishing device. To ensure the supporting effect of the retaining ring structure 200 and prevent the elastic sealing structure from falling off, the outer diameter of the retaining ring structure 200 is smaller than the inner diameter of the elastic sealing structure.

[0046] In one embodiment, the retaining ring structure 200 includes an arc-shaped retaining block arranged in a ring, and the elastic sealing structure is sleeved on the outer periphery of the arc-shaped retaining block. In this case, the angle corresponding to the outer arc of the arc-shaped retaining block is denoted as θ1, then 180° < θ1 ≤ 360°. This arrangement requires only one arc-shaped retaining block for the elastic sealing device.

[0047] In another embodiment therein, such as Figure 4 As shown, the retaining ring structure 200 includes two or more arc-shaped blocks, with the outer circumferential arcs of the two or more arc-shaped blocks on the same circle. The elastic sealing structure is fitted onto the outer circumference of the arc-shaped blocks. Here, the angle corresponding to the outer circumferential arc of the arc-shaped block is denoted as θ1, where 0° < θ1 ≤ 180°. It should be noted that when θ1 is less than 180°, the two or more arc-shaped blocks are dispersed on the same outer circumferential circle. Preferably, the two or more arc-shaped blocks are evenly spaced on the same outer circumferential circle. This arrangement ensures that the elastic sealing structure is uniformly stressed in the circumferential direction, thereby preventing irregular radial deformation when subjected to the forces of the fire extinguishing cover 900 and the reactor flange 700, thus ensuring the sealing performance of the fire extinguishing device. Furthermore, the θ1 corresponding to the two or more arc-shaped blocks can be the same or different, which will not be elaborated further here.

[0048] In one specific embodiment, the retaining ring structure 200 includes four arc-shaped blocks, all disposed on the same outer circumference and evenly spaced. The elastic sealing structure is fitted onto the outer circumference of the four arc-shaped blocks. Through the coordinated arrangement of the arc-shaped blocks and the elastic sealing structure, a uniform and stable support is formed on the outer circumference of the elastic sealing structure, thereby ensuring its sealing effect. To ensure the stability of the elastic sealing structure, the diameter of the outer circumference is larger than the inner diameter of the elastic sealing structure.

[0049] In this embodiment, there are four lifting lugs 100. The four lifting lugs 100 are arranged in pairs near the outer edge of the fire extinguishing cover 900. The line connecting the geometric center of the projection of the second protective cover 400 onto the fire extinguishing cover 900 and the geometric center of the fire extinguishing cover 900 is denoted as line segment M. The projection of the line connecting two of the four lifting lugs 100 onto the fire extinguishing cover 900 is collinear with line segment M, and the projection of the line connecting the other two lifting lugs 100 onto the fire extinguishing cover 900 forms a 90° angle with line segment M. It should be understood that when the reactor is placed horizontally, its first protective cover 600 may be in any position. If only one lifting lug 100 is installed, during fire extinguishing, the lifting lug 100 and the first protective cover 600 may be nearly 180° apart. In this case, the fire extinguishing cover 900 needs to be rotated significantly to align the second protective cover 400 with the first protective cover 600, which is time-consuming and laborious. With the above-mentioned arrangement, the projection of the line connecting the two opposing lifting lugs 100 on the fire extinguishing cover 900 is arranged in a "+" shape. The lifting lugs 100 can be evenly distributed on the periphery of the fire extinguishing cover 900 near the outer edge. Thus, during fire extinguishing, only a small rotation or no rotation of the fire extinguishing cover 900 is needed to align and assemble the second protective cover 400 with the first protective cover 600. This significantly improves the assembly speed of the fire extinguishing device and the reactor during the climbing titanium removal process and enhances its operational safety.

[0050] In another optional embodiment, there are eight lifting lugs 100. The eight lifting lugs 100 are arranged in pairs opposite to each other at positions close to the outer edge of the fire extinguishing cover plate 900. The two opposite lifting lugs 100 are regarded as a group, and there are a total of four groups. The line connecting the geometric center of the projection of the second protective cover 400 on the fire extinguishing cover plate 900 and the geometric center of the fire extinguishing cover plate 900 is denoted as line segment M. Among them, the projection of the connection line of the two lifting lugs 100 in the first group on the fire extinguishing cover plate 900 is collinear with line segment M, the projection of the connection line of the two lifting lugs 100 in the second group on the fire extinguishing cover plate 900 forms a 90° angle with line segment M, the projection of the connection line of the two lifting lugs 100 in the third group on the fire extinguishing cover plate 900 forms a 45° angle with line segment M, and the projection of the connection line of the two lifting lugs 100 in the fourth group on the fire extinguishing cover plate 900 forms a 135° angle with line segment M. Through the above settings, the projections of the connection lines of the four groups of lifting lugs 100 on the fire extinguishing cover plate 900 are arranged in a "rice" shape, and the eight lifting lugs 100 can be evenly arranged on the circumferential side of the fire extinguishing cover plate 900 close to the outer edge. Thus, when extinguishing a fire, it is only necessary to slightly adjust or not rotate the fire extinguishing cover plate 900 to align and assemble the second protective cover 400 with the first protective cover 600, significantly improving the assembly speed of the fire extinguishing device and the reactor during wall-climbing titanium removal and enhancing its working safety.

[0051] As one of the optional embodiments, as Figure 4 shown, the fire extinguishing cover plate 900 is circular, and the elastic sealing structure and the retaining ring structure 200 are circular ring structures. The diameter of the fire extinguishing cover plate 900 is denoted as Φ1, the inner diameter of the retaining ring structure 200 is denoted as Φ2, the outer diameter of the retaining ring structure 200 is denoted as Φ3, the inner diameter of the elastic sealing structure is denoted as Φ4, and the outer diameter of the elastic sealing structure is denoted as Φ5. Then Φ2 < Φ4 ≤ Φ3 < Φ5 < Φ1. Among them, the outer diameter of the retaining ring structure 200 is the diameter of the circle where its outer circumference is located, and its inner diameter is the diameter of the circle where the inner circumference of the retaining ring structure 200 is located. Through the setting of Φ5 < Φ1, there is a corresponding gap at the outer edge position of the fire extinguishing cover plate 900, and a G-clamp can be used for fixed connection. Through the setting of Φ2 < Φ4 ≤ Φ3 < Φ5, the retaining ring structure 200 and the elastic sealing structure are in interference fit, thus ensuring the installation stability of the elastic sealing structure and preventing it from falling off the retaining ring structure 200. It should be understood that the inner diameter of the opening position of the reactor is denoted as Φ6 (not marked in the drawing), and the outer diameter of the reactor flange 700 is denoted as Φ7 (not marked in the drawing). Then Φ6 < Φ5 < Φ7, and this setting can ensure that the elastic seal and the reactor cooperate to form a corresponding sealing structure. Preferably, in order to ensure that the fire extinguishing cover plate 900 and the reactor flange 700 can be fixedly connected through a G-clamp, Φ7 = Φ1.

[0053] This embodiment provides a horizontal fire extinguishing device for a titanium sponge reactor, which includes a fire extinguishing cover plate 900, lifting lugs 100, a retaining ring structure 200, an argon filling pipe 300, a second protective cover 400, an elastic sealing structure and G-clamps. Among them, there are four lifting lugs 100, and the four lifting lugs 100 are designed diagonally. The projection of the connection line of two of the lifting lugs 100 and the projection of the second protective cover 400 and the geometric center connection line of the fire extinguishing cover plate 900 are collinear or at a 90° angle. During use, according to the position of the first protective cover 600, the corresponding lifting lug 100 is selected to ensure the alignment and assembly of the second protective cover 400 and the first protective cover 600. The elastic sealing structure is a rubber pad 500. The retaining ring structure 200 is fixedly connected to the fire extinguishing cover plate 900. After the rubber pad 500 is tensioned, it is sleeved on the outer periphery of the retaining ring structure 200. The height of the retaining ring structure is lower than the compression thickness of the rubber pad 500, so as to ensure the compression seal between the rubber pad 500 and the reactor flange 700. An argon filling pipe 300 is arranged at the center of the fire extinguishing cover plate 900 to facilitate rapid argon filling for fire extinguishing. During use, the reactor is horizontally stored on a roller rack, and the reactor is rotated to a suitable position (convenient for aligning the first protective cover 600 and the second protective cover 400) for the peeling operation of the wall-climbing titanium. Once a fire occurs during the peeling process, the overhead crane hoists the fire extinguishing device to align it with the reactor flange 700, fixes it with G-clamps, and supplements argon through the argon filling pipe 300 to quickly extinguish the fire. Among them, the thickness of the fire extinguishing cover plate 900 is denoted as L1, the thickness of the elastic sealing structure is denoted as L2, and the height of the retaining ring structure 200 is denoted as L3 (not marked in the attached drawing). Among them, L1 is 10 - 100 mm, L2 is 20 - 200 mm, L3 is 10 - 190 mm, L3 < L2, 0° < θ1 ≤ 360°, Φ1 is 2500 - 4000 mm, Φ2 is 2200 - 3400 mm, Φ3 is Φ2 + (10 - 500) mm; Φ4 is Φ3 - (0 - 200) mm; Φ5 is Φ4 + (10 - 500) mm. When the fire extinguishing cover plate 900 is fixedly connected to the reactor flange 700, the elastic sealing structure is compressed and deformed, and its thickness after compression deformation is the compression thickness, which is denoted as L4, and L2 < L4 < L3.

[0057] This embodiment provides a horizontal fire extinguishing device for a titanium sponge reactor, which includes a fire extinguishing cover plate 900, lifting lugs 100, a retaining ring structure 200, an argon filling pipe 300, a second protective cover 400, an elastic sealing structure and G-clamps.
