Description

Technical Field

[0001] This invention relates to the field of magnesium smelting and purification technology, specifically to an assembled heat-resistant condenser. Background Technology

[0002] Traditional metal smelting furnaces typically have perforated baffles installed between the high-temperature zone and the crystallization zone inside. These baffles block heat radiation from the high-temperature zone without affecting the flow of magnesium vapor. However, traditional perforated baffles not only have poor heat insulation effects but also cannot filter impurities contained in magnesium vapor, resulting in poor magnesium smelting quality.

[0003] A type of heat-blocking interceptor has emerged, which creates a staged cooling effect by setting a curved flow channel inside the interceptor body. It not only has a good heat-blocking effect, but also filters impurities through staged cooling. However, most existing heat-blocking interceptors are one-piece structures. With use, impurities accumulate inside. To clean them, the interceptor body must first be cut, and after cleaning, it must be re-welded. In this process, the heat-blocking interceptor is easily damaged. Existing heat-blocking interceptors are difficult to clean and cannot be reused. If they are directly replaced, the cost of use is extremely high. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated heat-resistant condenser to solve the technical problems of existing heat-resistant interceptors, which are difficult to clean internal impurities and have high operating costs due to their integrated fixed structure. The preferred technical solutions provided by this invention can produce many technical effects, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The locking mechanism includes a locking member and a fastening member; the locking member is mounted on the front condenser body, and the fastening member is mounted on the rear condenser body; the fastening member can be locked onto the locking member.

[0007] Preferably, the front ladder condenser is configured as a barrel structure with one open end; the rear ladder condenser is configured as a barrel structure with one open end; when the front ladder condenser and the rear ladder condenser are connected, the open end of the front ladder condenser abuts against the open end of the rear ladder condenser; the air inlet is disposed on the end face of the front ladder condenser, and the air outlet is disposed on the end face of the rear ladder condenser.

[0008] Preferably, the edge of the rear ladder body end face extends outward along the axial direction to form an annular transition section, and the annular transition section forms a notch; the end edge of the annular transition section away from the front ladder body extends outward along the radial direction to form an annular mounting flange.

[0009] Preferably, the front trapezoidal condensate is provided with a first annular guide fluid, and the number of the first annular guide fluids is set to multiple, with all the first annular guide fluids sequentially nested from the inside to the outside to form a first guide cavity sequentially nested from the inside to the outside; the rear trapezoidal condensate is provided with a second annular guide fluid, and the number of the second annular guide fluids is set to multiple, with all the second annular guide fluids sequentially nested from the inside to the outside to form a second guide cavity sequentially nested from the inside to the outside; when the front trapezoidal condensate and the rear trapezoidal condensate are connected, the first annular guide fluid is inserted into the corresponding second guide cavity, and the second annular guide fluid is inserted into the corresponding first guide cavity to form an annular flow channel sequentially connected from the inside to the outside.

[0010] Preferably, the outermost annular flow channel is connected to the air inlet; the inner cavity of the innermost second annular guide fluid penetrates the rear trapezoidal condensate, and the port of the innermost second annular guide fluid away from the front trapezoidal condensate forms the air outlet.

[0011] Preferably, the bottom sidewall of the front ladder body is provided with a first positioning support portion, and the bottom sidewall of the rear ladder body is provided with a second positioning support portion. When the front ladder body and the rear ladder body are connected, the first positioning support portion and the second positioning support portion are aligned.

[0012] Preferably, the first positioning support part is configured as a first positioning support rib, and the first positioning support rib is axially arranged on the bottom side wall of the front ladder body; the second positioning support part is configured as a second positioning support rib, and the second positioning support rib is axially arranged on the bottom side wall of the rear ladder body.

[0013] Preferably, the locking component is configured as a locking post, which is disposed on the front ladder body. The rear ladder body has a guide hole adapted to the locking post at a position corresponding to the locking post. The locking post passes through the guide hole and is detachably connected to the locking fastener.

[0014] Preferably, the locking post is provided with a locking groove, the fixed end of the locking fastener is rotatably disposed on the rear ladder body, and the locking end of the locking fastener is provided as a hook that can be engaged in the locking groove.

[0015] Preferably, a limiting eave is provided on the outer wall of the locking post. When the locking post is connected to the locking fastener, the limiting eave abuts against the opening of the guide hole to seal the gap between the guide hole and the locking post.

[0016] The assembled heat-resistant condenser provided by this invention has at least the following beneficial effects:

[0017] The assembled heat-resistant condenser includes a front condenser body, a rear condenser body, and a locking mechanism. The locking mechanism is used to connect the front condenser body and the rear condenser body, which are installed inside the metal smelting furnace body.

[0018] The front condenser is detachably mounted on the rear condenser. Both the front and rear condensers have curved gas channels. The front condenser has an inlet connected to the gas channels, and the rear condenser has an outlet connected to the gas channels. During the magnesium smelting process, magnesium vapor in the high-temperature zone enters the gas channels through the inlet and exits through the outlet. In this process, the curved gas channels cause the temperature to decrease gradually, thereby causing impurities in the magnesium vapor to separate and condense in the front and rear condensers. This not only has a good heat insulation effect but also effectively filters impurities and improves the quality of magnesium smelting.

[0019] The locking mechanism includes a locking element and a fastening element. The locking element is located on the front ladder condenser, and the fastening element is located on the rear ladder condenser. In use, the locking element and the fastening element cooperate to firmly lock the front and rear ladder condensers, thereby ensuring their effectiveness. When cleaning impurities, the locking element and the fastening element are released, allowing the front and rear ladder condensers to be disassembled and their internal impurities to be cleaned without damaging the ladder condenser. The cleaning operation is convenient and allows for repeated use of the device, thus significantly reducing operating costs.

[0020] The preferred embodiments of this application also have at least the following beneficial effects:

[0021] The concave structure formed by the annular transition section on the rear condenser end face is far from the crystallization end, which can reduce the radiation temperature and allow magnesium vapor to pass through smoothly, avoiding magnesium crystallization and blockage in the condenser and preventing the problem of furnace combustion caused by the precipitation of crystalline magnesium.

[0022] The positioning support ribs on the front and rear ladder condensers serve a positioning function, which helps to install the ladder condenser and reduction tank concentrically and prevents magnesium vapor from leaking from the edge of the ladder condenser.

[0023] The gas flow channel is formed by interlocking annular guide fluids, and has an annular structure that is distributed in layers from the inside to the outside. There are cooling gradients in both the axial and radial directions, which facilitates the separation and deposition of impurities. At the same time, it can increase the cross-sectional area, which facilitates the deposition of condensed impurities. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] Example 1:

[0039] This invention provides a prefabricated heat-resistant condenser, such as... Figure 1 and Figure 2 As shown, the assembled heat-resistant condenser includes a front condenser body 1, a rear condenser body 2, and a locking mechanism 3.

[0040] The front trapezoidal condenser 1 is detachably mounted on the rear trapezoidal condenser 2. Both the front trapezoidal condenser 1 and the rear trapezoidal condenser 2 are provided with curved gas flow channels. The front trapezoidal condenser 1 is provided with an air inlet 11 that communicates with the gas flow channels, and the rear trapezoidal condenser 2 is provided with an air outlet 21 that communicates with the gas flow channels.

[0041] The locking mechanism 3 includes a locking member 31 and a locking fastener 32. The locking member 31 is disposed on the front ladder body 1, and the locking fastener 32 is disposed on the rear ladder body 2. The locking fastener 32 can be locked onto the locking member 31.

[0042] refer to Figure 8 As shown, in use, the front ladder condenser 1 is located on the rear ladder condenser 2, and the locking fastener 32 is locked to the locking member 31, thereby locking the front ladder condenser 1 and the rear ladder condenser 2. The assembled heat-resistant ladder condenser is installed inside the furnace body 4 of the metal smelting furnace.

[0043] During magnesium smelting, the raw materials in the high-temperature zone of the furnace generate magnesium vapor. The magnesium vapor enters the gas flow channel through the gas inlet 11 and is then discharged through the gas outlet 21.

[0044] During the above process, the curved gas flow channel causes the temperature gradient to decrease gradually. On the one hand, it can effectively block the heat radiation of the high-temperature zone inside the metal smelting furnace body 4. On the other hand, impurities in magnesium vapor will be separated and condensed into the gas flow channel step by step, playing the role of filtering impurities.

[0045] When cleaning impurities, release the locking state between locking member 31 and locking member 32, remove the front ladder body 1 and the rear ladder body 2, and then clean the internal impurities. After cleaning, install the front ladder body 1 and the rear ladder body 2, and lock the locking member 32 onto the locking member 31.

[0046] The present invention, through the cooperation of locking member 31 and locking buckle 32, can not only firmly lock the front ladder body 1 and the rear ladder body 2, making the structure robust, but also allows the front ladder body 1 and the rear ladder body 2 to be disassembled by releasing the locking state, making disassembly and assembly convenient, enabling reuse, and reducing the cost of use.

[0047] Example 2

[0048] Example 2 is based on Example 1:

[0049] like Figures 1-4 As shown, the front ladder body 1 is configured as a barrel structure with one open end, and the rear ladder body 2 is configured as a barrel structure with one open end. When the front ladder body 1 and the rear ladder body 2 are connected, the open end of the front ladder body 1 abuts against the open end of the rear ladder body 2.

[0050] The air inlet 11 is located on the end face of the front trapezoidal condenser 1, which is the air inlet end face. The air outlet 21 is located on the end face of the rear trapezoidal condenser 2, which is the air outlet end face. Under the premise that the front trapezoidal condenser 1 and the rear trapezoidal condenser 2 are detachable and the gas flow is smooth, the front trapezoidal condenser 1 and the rear trapezoidal condenser 2 can form a closed cavity, which is convenient for impurity collection.

[0051] As an optional implementation, such as Figure 4 As shown, the edge of the air outlet end face of the rear condensate 2 extends outward along the axial direction to form an annular transition section 26, which forms a notch.

[0052] In practical use, the main body of the heat-resistant condenser is located in the high-temperature zone of the smelting furnace. The annular transition section 26 creates a concave structure on one side of the outlet end of the heat-resistant condenser, ensuring that the internal flow channel and the end face of the outlet end of the heat-resistant condenser are completely placed within the high-temperature zone. This not only facilitates the flow and removal of magnesium vapor but also effectively prevents magnesium vapor from condensing inside and at the outer edges of the condenser, making it easier to disassemble and clean internal impurities. Furthermore, magnesium vapor is less likely to condense on the end face of the outlet end of the condenser, solving the combustion problem caused by magnesium condensation on the outlet end face when the condenser is removed from the furnace. On the other hand, it effectively prevents the large-headed magnesium on the crystallizer located in the low-temperature zone of the smelting furnace from contacting the outlet end of the heat-resistant condenser, preventing adhesion. This not only effectively reduces the difficulty of removing the heat-resistant condenser and the crystallizer inside the smelting furnace but also effectively improves the combustion problem of the large-headed magnesium during crystallizer removal.

[0053] The locking element 32 is located inside the annular transition section 26, which also serves to accommodate the locking mechanism 3.

[0054] like Figure 4 and Figure 5 As shown, the annular transition section 26 extends radially outward from the end edge away from the front ladder body 1 and forms an annular mounting flange 27, as shown in the reference. Figure 8 As shown, the annular mounting flange 27 is used for the installation of the assembled heat-resistant condenser, ensuring a stable installation and achieving a seal.

[0055] As an optional implementation, such as Figures 3-6 As shown, a first annular guide fluid 12 is provided inside the front trapezoidal body 1. The number of first annular guide fluids 12 is set to multiple. All the first annular guide fluids 12 are nested from the inside to the outside, so that the front trapezoidal body 1 forms a first guide cavity 13 nested from the inside to the outside. The innermost first guide cavity 13 is a cylindrical cavity, and the outermost first guide cavity 13 is an annular cavity.

[0056] The rear stepped condensate 2 is provided with a second annular guide fluid 23. The number of second annular guide fluids 23 is set to multiple. All the second annular guide fluids 23 are arranged sequentially from the inside to the outside, so that the interior of the rear stepped condensate 2 forms a second guide cavity 24 nested sequentially from the inside to the outside. The innermost second guide cavity 24 is a cylindrical cavity, and the outermost second guide cavity 24 is an annular cavity.

[0057] The sum of the axial length of the barrel structure of the front ladder condensate 1 and the axial length of the barrel structure of the rear ladder condensate 2 is greater than the axial length of the first annular guide fluid 12.

[0058] The sum of the axial length of the barrel structure of the front ladder condensate 1 and the axial length of the barrel structure of the rear ladder condensate 2 is greater than the axial length of the second annular guide fluid 23.

[0059] The inner diameter of the innermost first annular guide fluid 12 is larger than the outer diameter of the innermost second annular guide fluid 23.

[0060] When the front ladder condenser 1 and the rear ladder condenser 2 are connected, the first annular guide fluid 12 is inserted into the corresponding second guide cavity 24, and the second annular guide fluid 23 is inserted into the corresponding first guide cavity 13, thereby forming an annular flow channel that is sequentially connected from the inside to the outside.

[0061] The gas flow channel is formed by the annular flow channels connected sequentially from the inside to the outside. This structure not only gives the condenser a cooling gradient in both the axial and radial directions, resulting in significant heat insulation and filtration effects, but also allows for the disassembly and separation of the front condenser 1 and the rear condenser 2, both of which are open structures, facilitating the cleaning of impurities inside them.

[0062] Optionally, the number of first annular guide fluid 12 is set to two, and the number of second annular guide fluid 23 is set to two.

[0063] Similarly, depending on actual usage requirements, a corresponding number of first annular guide fluids 12 and second annular guide fluids 23 can be set to obtain a corresponding degree of cooling effect.

[0064] As an optional implementation, such as Figure 6 As shown, the outermost annular flow channel is connected to the air inlet 11, which includes multiple elongated holes.

[0065] The innermost second annular guide fluid 23 penetrates the rear ladder condensate 2, and the port of the innermost second annular guide fluid 23 away from the front ladder condensate 1 forms an air outlet 21.

[0066] refer to Figure 7 As shown, the magnesium vapor in the assembled heat-resistant condenser adopts an external inlet and internal outlet gas flow mode.

[0067] like Figure 2 As shown, the air inlet 11 is located in the upper section of the air inlet end face of the front trapezoid 1 and is evenly distributed along the circumference, while the lower section of the air inlet end face is sealed.

[0068] During the magnesium smelting process, if raw material particles enter the condenser, the magnesium produced by the reaction will adhere to the front condenser 1 and the rear condenser 2, affecting their disassembly and increasing the difficulty of cleaning. The inlet end face adopts a semi-sealed structure with the top inlet and the bottom sealed. Without affecting the gas flow, it can effectively block the raw material particles piled up in the furnace body from entering the condenser, avoiding the aforementioned adhesion phenomenon and facilitating the cleaning of impurities.

[0069] Optionally, such as Figures 1-4As shown, the locking member 31 is located at the end of the innermost first annular guide fluid 12 of the front trapezoidal body 1, and the fixing shaft is located outside the guide hole 22.

[0070] Alternatively, such as Figure 9 and Figure 10 As shown, the locking member 31 is located at the end of the outermost first annular guide fluid 12 of the front trapezoidal body 1, and the fixed shaft is located inside the guide hole 22.

[0071] The assembled ladder condenser comes in a variety of types.

[0072] As an optional implementation, the bottom side wall of the front ladder 1 is provided with a first positioning support 14, and the bottom side wall of the rear ladder 2 is provided with a second positioning support 25. When the front ladder 1 and the rear ladder 2 are connected, the first positioning support 14 and the second positioning support 25 are aligned.

[0073] The first positioning support 14 and the second positioning support 25 cooperate with each other, providing both support and positioning, ensuring that the front ladder body 1 and the rear ladder body 2 are coaxially connected, and effectively ensuring the sealing effect of the annular mounting flange 27.

[0074] As an optional implementation, such as Figure 2 As shown, the first positioning support part 14 is configured as a first positioning support rib, and the first positioning support rib is axially arranged on the bottom side wall of the front trapezoidal body 1.

[0075] The second positioning support part 25 is configured as a second positioning support rib, which is axially arranged on the bottom side wall of the rear trapezoidal body 2.

[0076] The positioning support adopts a rib structure, which is simple in structure and has a significant positioning and support effect.

[0077] like Figure 3 and Figure 4 As shown, the locking component 31 is configured as a locking post 311, which is mounted on the front ladder body 1 and is integrally mounted with the front ladder body 1.

[0078] The rear ladder body 2 has a guide hole 22 that matches the locking post 311 at the position corresponding to the locking post 311. The locking post 311 passes through the guide hole 22 and is detachably connected to the locking fastener 32.

[0079] The guide hole 22 has a significant positioning and guiding effect. When the front ladder body 1 and the rear ladder body 2 are installed, it can effectively guide the locking pin 311 to the position of the locking fastener 32, which facilitates the locking and unlocking of the locking mechanism 3. At the same time, it is compatible with the locking pin 311 and has a limiting function, which can effectively prevent the front ladder body 1 and the rear ladder body 2 from shifting.

[0080] As an optional implementation, such as Figure 3 As shown, the locking post 311 is provided with a locking groove 3111.

[0081] A fixed shaft is provided on the end face of the rear ladder body 2. The fixed end of the locking fastener 32 is rotatably mounted on the fixed shaft. The locking end of the locking fastener 32 is configured as a hook 321, which is adapted to the locking groove 3111.

[0082] When connecting the front ladder body 1 and the rear ladder body 2, move the locking fastener 32 to make the hook 321 engage in the locking groove 3111.

[0083] This design uses a snap-fit ​​connection method, resulting in a simple structure that is sturdy during installation and easy to assemble and disassemble.

[0084] As an optional implementation, such as Figure 3 As shown, a limiting eave 3112 is provided on the outer wall of the locking post 311.

[0085] When the locking post 311 is connected to the locking fastener 32, the limiting eaves 3112 abuts against the opening of the guide hole 22. At this time, the limiting eaves 3112 blocks the gap between the guide hole 22 and the locking post 311, and the locking post 311 is inserted into place, and the locking groove 3111 corresponds to the locking fastener 32.

[0086] The limiting eaves 3112 serves two purposes: firstly, it limits the movement of the locking post 311 and the locking fastener 32; secondly, it provides a sealing function, sealing the gap between the guide hole 22 and the locking post 311 and improving the airtightness.

[0087] As an optional implementation, the number of locking pins 311, guide holes 22 and locking members 31 are the same, and each is provided in multiples.

[0088] Preferably, such as Figure 3 and Figure 4 As shown, the number of locking pins 311, guide holes 22, and locking components 31 are all set to two.
