Description

Technical Field

[0001] The utility model belongs to the field of metal magnesium smelting and purification, and specifically relates to a metal vapor semi-enclosed heat-resistant condenser. Background Art

[0002] Taking magnesium metal as an example, in the smelting process of magnesium metal, a heat-resistant gradient condenser is often needed to gradient cool the magnesium vapor and remove impurities in the magnesium vapor during the cooling process.

[0003] However, during the use of the condenser, the spherical particle raw materials in the reduction tank will enter the condenser through the holes and block the magnesium vapor channel in the condenser, affecting the normal purification of crude magnesium.

[0004] Based on this, the technical solution of the utility model is proposed, and the effects of reducing the entry of dust, dividing areas and gradient cooling are achieved. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a metal vapor semi-enclosed heat-resistant ladder condenser. The metal vapor semi-enclosed heat-resistant ladder condenser is sealed at the lower area of ​​the air inlet end, directly blocking the path of the spherical granular raw materials in the reduction tank entering the heat-resistant ladder condenser, avoiding the situation of internal blockage of the heat-resistant ladder condenser; and because the ladder condenser adopts a detachable structure, it is more convenient to clean and maintain it later.

[0006] The utility model provides a metal vapor semi-enclosed heat-resistant ladder condenser, comprising a ladder condenser body, wherein:

[0007] The ladder condenser body is provided with an air inlet end, an air outlet end and a flow channel, and the flow channel is provided inside the ladder condenser body;

[0008] The upper section of the air inlet end is provided with an air inlet hole and the lower section is closed, and the air outlet end is provided with an air outlet hole;

[0009] One end of the flow channel is connected to the air inlet, and the other end is connected to the air outlet, so that metal vapor enters the interior of the condenser body from the air inlet, passes through the flow channel, and then flows out from the air outlet.

[0010] In order to facilitate the understanding of the present invention, the technical solution of the present invention is described by taking magnesium metal as an example:

[0011] In actual use, a metal vapor semi-closed heat-resistant ladder condenser (hereinafter referred to as the heat-resistant ladder condenser) is located at the outlet of the magnesium metal reduction tank. Under the high temperature conditions of the reduction tank, magnesium vapor enters the heat-resistant ladder condenser from the air inlet hole in the upper section of the air inlet end. At the same time, since the lower section of the air inlet end is closed, the spherical particle raw materials in the reduction tank can be effectively prevented from entering the heat-resistant ladder condenser, thereby avoiding the crystallization adhesion and dust pollution in the heat-resistant ladder condenser; then the magnesium vapor will move along the flow channel inside the heat-resistant ladder condenser. Due to the radial temperature gradient of the heat-resistant ladder condenser, the temperature of the metal vapor will gradually decrease during the flow process, and the impurity elements in the metal vapor will condense and crystallize in the ladder condenser at an appropriate temperature, thereby achieving the purpose of impurity removal. At the same time, the purity of the magnesium vapor is further improved, and finally the magnesium vapor flows out from the air outlet hole at the air outlet end, continues the next step of crystallization, and finally forms high-purity magnesium crystals in the crystallizer (the travel path of the magnesium vapor is as shown in FIG. Figure 6 shown).

[0012] Preferably, the cross section of the air inlet end is set to be circular, and the air inlet holes are evenly arranged along the circumference of the upper section.

[0013] Preferably, the flow channel is an annular flow channel; wherein:

[0014] The annular flow channels are sequentially sleeved from the inside to the outside along the interior of the ladder condenser body, and adjacent annular flow channels are sequentially connected.

[0015] Preferably, the air inlet is connected to the outermost annular flow channel, and the air outlet is connected to the innermost annular flow channel.

[0016] Preferably, the air inlet end is provided with an assembly connection plate, and the air outlet end is provided with an assembly hole; wherein:

[0017] The assembly connecting plate is connected through the assembly hole so that the air outlet end and the air inlet end cover are embedded.

[0018] Preferably, the metal vapor semi-enclosed heat-resistant condenser further comprises a locking component; wherein:

[0019] The locking component is provided with a locking hook, and the assembly connecting plate is provided with a hook groove; the locking hook can be embedded in the hook groove and locked with the assembly connecting plate.

[0020] Preferably, the locking component is provided with a pin hole, and the air outlet end is provided with a fixing pin; wherein:

[0021] The fixing pin passes through the pin hole and is used to limit the locking component.

[0022] Preferably, the gas outlet end is provided with a gas outlet end surface, an annular wall and an annular convex eaves; wherein:

[0023] The annular wall is arranged around the gas outlet end surface to form a groove;

[0024] The annular convex eave is arranged on the top of the annular wall to form a section extending outwards.

[0025] The beneficial effects of the utility model are:

[0026] The metal vapor semi-sealed heat-resistant ladder condenser described in the utility model closes the lower area of ​​the air inlet end, directly blocking the path of the spherical particle raw materials in the reduction tank entering the heat-resistant ladder condenser, avoiding blockage inside the heat-resistant ladder condenser; and because the ladder condenser adopts a detachable structure, later cleaning and maintenance are also more convenient.

[0027] The preferred solution of the utility model also has the following beneficial effects:

[0028] The semi-enclosed heat-resistant ladder condenser needs to be placed at the outlet of the high-temperature reduction tank, and the gas outlet end is flush with the outlet of the high-temperature reduction tank. The gas outlet end is set in a groove shape, which can make the ladder condenser body extend to the high-temperature section of the high-temperature reduction tank, thereby making the flow channel temperature inside the ladder condenser body higher, which is more conducive to the circulation and impurity removal of magnesium vapor; in addition, since the overall temperature of the ladder condenser is relatively high, magnesium vapor is not easy to condense at the connection between the ladder condenser and the high-temperature reduction tank, which is convenient for the later removal and replacement of the ladder condenser from the reduction tank, and also improves the problem of "big head magnesium". At the same time, the higher temperature also makes it difficult for magnesium vapor to crystallize inside the ladder condenser, which is more conducive to opening and cleaning after the ladder condenser is removed.

[0029] That is, setting the outlet end into a groove shape (which can be understood as a heat-resistant condenser with an outer eaves) can isolate the distance between the open end face and the crystallization end face, effectively reduce the temperature of the crystallization end face, avoid high-temperature combustion, and at the same time improve the crystallization efficiency of magnesium vapor, avoiding crystallization to the end face due to increased steam partial pressure.

[0044] Example 1

[0045] refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 This embodiment provides a metal vapor semi-enclosed heat-resistant ladder condenser, including a ladder condenser body 1, wherein:

[0046] The ladder condenser body 1 is provided with an air inlet 2, an air outlet 3 and a flow channel 4, and the flow channel 4 is provided inside the ladder condenser body 1; in addition, the air outlet 3 and the air inlet 2 are provided with a removable cover that is interlocked and connected. With such a configuration, when cleaning impurities, it is more convenient to directly disassemble and clean the inside.

[0047] The upper section of the air inlet end 2 is provided with an air inlet hole 21 and the lower section is closed, and the air outlet end 3 is provided with an air outlet hole 31;

[0048] One end of the flow channel 4 is connected to the air inlet 21 , and the other end is connected to the air outlet 31 , so that metal vapor enters the interior of the condenser body 1 from the air inlet 21 , passes through the flow channel 4 and then flows out from the air outlet 31 .

[0049] Example 2

[0050] refer to Figure 2 As an optional embodiment, the cross section of the air inlet end 2 is set to be circular, and the air inlet holes 21 are evenly arranged along the circumference of the upper section. The air inlet holes 21 are actually the air inlet of magnesium vapor. Such a setting can increase the amount of magnesium vapor entering per unit time, and at the same time make the magnesium vapor enter evenly, which can improve efficiency.

[0051] Example 3

[0052] refer to Figure 3 and Figure 4 As an optional embodiment, the flow channel 4 is an annular flow channel; wherein:

[0053] The annular flow channel is sequentially arranged from the inside to the outside of the ladder condenser body 1, and adjacent annular flow channels are sequentially connected. The flow channel 4 is arranged in an annular shape, so that the length of the flow channel can be extended as much as possible. On the one hand, the temperature of the magnesium vapor can be gradually reduced, which is beneficial to the subsequent magnesium crystallization process; on the other hand, impurities can be fully crystallized and condensed inside the ladder condenser body 1, so as to further purify the magnesium vapor.

[0054] refer to Figure 3 and Figure 4 As an optional embodiment, the air inlet 21 is connected to the outermost annular flow channel, and the air outlet 31 is connected to the innermost annular flow channel. In this configuration, the air inlet 21 is actually located outside the upper section of the air inlet end 2, and the air outlet 31 is located in the middle of the air outlet end 3. At this time, the magnesium vapor can be evenly filled into the subsequent cavity after flowing out, so as to form high-purity magnesium crystals.

[0055] Example 4

[0056] refer to Figure 3 As an optional embodiment, the air inlet end 2 is provided with an assembly connecting plate 22, and the air outlet end 3 is provided with an assembly hole 32; wherein:

[0057] The assembly connecting plate 22 is connected to the assembly hole 32 so that the air outlet 3 is covered and embedded with the air inlet 2. Such an arrangement can make the air inlet 2 and the air outlet 3 embedded more tightly and not easy to fall off.

[0058] refer to Figure 3 and Figure 5 As an optional embodiment, the metal vapor semi-enclosed heat-resistant condenser further includes a locking component 5; wherein:

[0059] The locking component 5 is provided with a locking hook 51, and the assembly connecting plate 22 is provided with a hook groove; the locking hook 51 can be inserted into the hook groove and locked with the assembly connecting plate 22. In this way, the locking component 5 and the assembly connecting plate 22 can be relatively locked, and the fitting tightness of the air inlet end 2 and the air outlet end 3 can be further improved.

[0060] refer to Figure 3 and Figure 5 As an optional embodiment, the locking component 5 is provided with a pin hole 52, and the air outlet end 3 is provided with a fixing pin 33; wherein:

[0061] The fixing pin 33 passes through the pin hole 52 and is used to limit the locking component 5. In this way, the locking component 5 can be limited, thereby further improving the fitting tightness of the air inlet end 2 and the air outlet end 3.

[0062] Example 5

[0063] refer to Figure 3 As an optional embodiment, a bracket 11 is provided at the lower part of the condenser body 1 to stably place the metal vapor semi-enclosed heat-resistant condenser. After being stably placed, the center of the heat-resistant condenser can be ensured to be concentric with the reduction tank, thereby ensuring the sealing effect of the heat-resistant condenser and the reduction tank opening.

[0064] Example 6

[0065] refer to Figure 7 As an optional embodiment, the outlet end is provided with an outlet end surface 34, an annular wall 35 and an annular convex eave 36; wherein:

[0066] The annular wall 35 is disposed around the gas outlet end surface 34 to form a groove;

[0067] The annular convex eave 36 is disposed on the top of the annular wall 35 to form a section extending outward.

[0068] It should be emphasized that in actual use, the semi-enclosed heat-resistant ladder condenser needs to be placed at the outlet of the high-temperature reduction tank, and the gas outlet end 3 is flush with the outlet of the high-temperature reduction tank. The gas outlet end 3 is set in a groove shape, so that the ladder condenser body 1 can extend to the high-temperature section of the high-temperature reduction tank, thereby making the flow channel 4 inside the ladder condenser body 1 higher in temperature, which is more conducive to the circulation and impurity removal of magnesium vapor; in addition, since the overall temperature of the ladder condenser is relatively high, magnesium vapor is not easy to condense at the junction of the ladder condenser and the high-temperature reduction tank, which is convenient for the later removal and replacement of the ladder condenser from the reduction tank, and also improves the problem of "big head magnesium". At the same time, the higher temperature also makes it difficult for magnesium vapor to crystallize inside the ladder condenser, which is more conducive to opening and cleaning after the ladder condenser is removed.

[0069] As an optional implementation, refer to Figure 7 The bottom of the ladder condenser body 1 is provided with positioning ribs 37, and the positioning ribs 37 are arranged in pairs, which have a supporting function on the one hand and a positioning and centering function on the other hand. In actual use, the ladder condenser body 1 can be ensured to be coaxial with the high-temperature reduction tank, the filtration area, and the low-temperature crystallization area, so as to achieve the effect of fast crystallization speed and central crystallization.

[0070] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
