Description

Technical Field

[0001] The utility model relates to the technical field of metal magnesium smelting and purification, and in particular to a plug-in type heat-resistant condenser. Background Art

[0002] At present, thermal reduction is usually used to smelt metallic magnesium, and the reduction tank device in the metal smelting furnace is indispensable as a key equipment in the magnesium smelting process. The traditional reduction tank device usually has a perforated fire baffle plate inside it. Under the premise of not affecting the circulation of magnesium vapor, the heat radiation is blocked by the plate itself. The traditional fire baffle plate not only has poor heat resistance effect, but also cannot filter impurities in the magnesium vapor, resulting in poor magnesium smelting quality. Nowadays, a heat-resistant interceptor has appeared. By setting a flow channel in the interceptor body, a phased cooling is formed inside it, so as to improve the heat resistance effect and the quality of magnesium smelting. However, as the heat-resistant interceptor continues to work, impurities on it continue to accumulate. If it is cleaned, it is often necessary to cut the interceptor body and weld it after the impurities are cleaned. Not only is the cleaning operation extremely troublesome, but it is also very easy to damage the interceptor and make it lose its function. Therefore, the existing heat-resistant interceptor cannot be reused many times and needs to be replaced frequently, which greatly increases the cost of use. Utility Model Content

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0038] Embodiment 1:

[0039] The utility model provides a plug-in heat-resistant condenser. Figure 1-Figure 3 As shown, the plug-in heat-resistant condenser includes a condenser body 1 and a plug-in board 2.

[0040] A flow guide cavity is provided in the condenser body 1, the air inlet end of the condenser body 1 is connected to the flow guide cavity and an air inlet 111 is provided, the air outlet end of the condenser body 1 is connected to the flow guide cavity and an air outlet 131 is provided, the plug-in board 2 is inserted into the flow guide cavity, and an overflow port 21 is provided on the plug-in board 2.

[0041] The air inlet 111 and the flow port 21 are arranged alternately, and the air outlet 131 and the flow port 21 are arranged alternately. The air inlet 111, the flow port 21 and the air outlet 131 are arranged alternately in sequence to form a curved flow channel.

[0042] During installation, the plug-in board 2 is plugged into the condenser body 1 .

[0043] When smelting metal magnesium, magnesium vapor enters the condenser body 1 from the air inlet 111 , flows through the flow port 21 , and then flows out from the air outlet 131 .

[0044] In the above process, due to the staggered distribution of the air inlet 111, the flow port 21 and the air outlet 131 forming a curved flow channel, the magnesium vapor is gradually cooled down during the flow in the condenser body 1. On the one hand, it can block the heat radiation of the metal smelting furnace in the high-temperature section of the furnace. On the other hand, the impurities in the magnesium vapor can condense in the condenser body 1 and on the plug-in board 2, thereby filtering out impurities.

[0045] When cleaning impurities, the plug-in board 2 is pulled out, and the impurities on the plug-in board 2 and the condenser body 1 are cleaned. After the cleaning is completed, the plug-in board 2 is plugged into the condenser body 1 again.

[0046] The connection structure between the plug-in board 2 and the ladder condenser body 1 adopts plug-in, and there is no need to damage the ladder condenser itself. The disassembly and assembly are convenient, thereby facilitating the cleaning of impurities on the plug-in board 2 and the ladder condenser body 1, facilitating the repeated use of the plug-in heat-resistant ladder condenser, and the use cost is low.

[0047] As an optional implementation, Figure 3 and Figure 4 As shown, the condenser body 1 includes a first end plate 11, a flow guide 12 and a second end plate 13 which are connected in sequence.

[0048] The air inlet 111 is disposed on the first end plate 11 , and the air outlet 131 is disposed on the second end plate 13 .

[0049] The flow guiding cavity is arranged in the flow guiding body 12 , and the plug board 2 , the first end board 11 and the second end board 13 are arranged in parallel.

[0050] The first end plate 11 is an air inlet end plate, the second end plate 13 is an air outlet end plate, and the guide body 12 can guide the magnesium vapor inside thereof and effectively block heat radiation without affecting the circulation of the magnesium vapor.

[0051] As an optional implementation, Figure 4 As shown, the air inlet 111 is arranged at the upper section of the first end plate 11 , and the flow opening 21 is arranged at the lower section of the plug board 2 .

[0052] During the process of smelting magnesium, if the raw material particles enter the condenser body 1, the magnesium produced by the reaction will adhere to the plug-in plate 2 and the condenser body 1, affecting the disassembly of the plug-in plate 2 and the condenser body 1, thereby increasing the difficulty of cleaning. The first end plate 11 adopts a semi-sealed structure of top-in and bottom-sealed. Under the premise of not affecting the gas flowability, it can effectively block the raw material particles piled in the reduction tank from entering the interior of the condenser body 1, avoid the occurrence of the aforementioned adhesion phenomenon, and facilitate the cleaning of impurities.

[0053] As an optional implementation, Figure 1 As shown, the air outlet 131 is arranged at the middle position of the second end plate 13 .

[0054] like Figure 4 and Figure 5 As shown, the first end plate 11 and the second end plate 13 are both circular end plates, the air inlet 111 includes a semicircular air inlet hole 1111 and a fan-ring air inlet hole 1112 which are cocentrically arranged, the semicircular air inlet hole 1111 is located at the center of the first end plate 11, the two fan-ring air inlet holes 1112 are symmetrically arranged relative to the semicircular air inlet hole 1111, the air outlet 131 is arranged as a circular air outlet, the flow port 21 includes a fan-shaped flow hole 211, the two fan-shaped flow holes 211 are arranged in the lower section of the plug-in board 2, and are located on both sides of the circular air outlet, and the two fan-shaped flow holes 211 are symmetrically arranged.

[0055] With such arrangement, not only the gas flows smoothly, but also the air inlet 111, the flow port 21 and the air outlet 131 are staggered in sequence to form a curved flow channel, thereby ensuring the heat-blocking and impurity-removing effects.

[0056] As an optional implementation, Figure 4 As shown, the flow guide 12 is configured as a semi-cylindrical structure that is axially penetrated and has open top and side walls. The top end of the flow guide 12 forms an open end, and the inner cavity of the flow guide 12 forms the flow guide cavity.

[0057] When assembling the plug-in heat-resistant condenser, the lower section of the plug-in board 2 is inserted into the guide cavity along the open end. The guide body 12 with a semi-cylindrical structure not only has a good guide effect, but also has open top and side walls, which further facilitates the disassembly and assembly operations of the plug-in board 2.

[0058] As an optional implementation, the inner wall of the flow guide 12 is provided with a limiting slot 121, the limiting slot 121 is adapted to the plug board 2, the lower section of the plug board 2 passes through the limiting slot 121, and the plug board 2 is firmly plugged in.

[0059] like Figure 3 and Figure 4 As shown, the number of the limiting slots 121 is set to two, the two limiting slots 121 are arranged opposite to each other, and the left and right sides of the lower section of the plug-in board 2 are interspersed with corresponding limiting slots 121.

[0060] Two limiting structures are relatively arranged on the inner wall of the flow guide 12 . The limiting structures include two limiting strips arranged in parallel. The gap between the two limiting strips forms a limiting slot 121 . The structure is simple and the limiting plug-in effect is significant.

[0061] As an optional implementation, Figure 2-Figure 5 As shown, the plug board 2 is provided with a first abutting surface 22 . When the bottom of the plug board 2 is plugged into the inner bottom wall of the flow guide 12 , the first abutting surface 22 abuts against the open end of the flow guide 12 .

[0062] The upper section and the lower section of the plug board 2 are both arranged in a semicircular shape. The semicircular upper section and the semicircular lower section are arranged concentrically. The bottom surface of the semicircular upper section is located on both sides of the semicircular lower section to form a first abutting surface 22.

[0063] The diameter of the lower section of the plug board 2 is the same as the inner diameter of the flow guide 12, the diameter of the upper section of the plug board 2, the outer diameter of the flow guide 12 and the diameter of the first end plate 11 are the same, the diameter of the second end plate 13 is larger than the outer diameter of the flow guide 12, and the edge section of the second end plate 13 forms an annular mounting flange, refer to Figure 6 As shown, the annular mounting flange is used for mounting the plug-in thermal resistance condenser.

[0064] Example 2

[0067] In actual use, the corresponding number of plug-in boards 2 can be selected according to needs. It is not only flexible and convenient to use and has a wide range of applications, but also the number and position can be freely adjusted to better adapt to the temperature zone of the tank mouth. The coordination of the temperature zone and the plug-in board further improves the filtering and impurity removal effects.

[0068] The plug-in boards 2 of Embodiments 1 and 2 adopt a lower section plug-in structure.

[0069] Example 3

[0070] The difference between Example 3 and Example 1 is that:

[0071] like Figure 8-Figure 13 As shown, the open end of the guide body 12 extends upward at the same arc as the guide body 12 to form an extended limit section 122 .

[0072] A limiting groove 1221 is provided on the extended limiting section 122 . The limiting groove 1221 is matched with the plug board 2 , and the upper section of the plug board 2 is inserted into the limiting groove 1221 .

[0073] The plug-in board 2 is provided with a second abutting surface 23 . When the bottom of the plug-in board 2 is plugged into the inner bottom wall of the flow guide 12 , the second abutting surface 23 abuts against the bottom of the limiting groove 1221 .

[0074] The upper section of the plug board 2 is arranged in a fan shape, and the lower section is arranged in a fan shape. The diameter of the fan-shaped upper section is larger than the diameter of the fan-shaped lower section. The bottom surface of the fan-shaped upper section is located on both sides of the fan-shaped lower section to form a second abutment surface 23, and the limiting groove 1221 is adapted to the fan-shaped upper section.

At this time, the upper section of the plug-in board 2 is semicircular, and the lower section of the plug-in board 2 is semicircular.

[0076] Example 4

[0079] In actual use, the corresponding number of plug-in boards 2 can be selected according to needs. It is not only flexible and convenient to use and has a wide range of applications, but also the number and position can be freely adjusted to better adapt to the temperature zone of the tank mouth. The coordination of the temperature zone and the plug-in board further improves the filtering and impurity removal effects.

[0080] The plug-in boards 2 of Embodiments 3 and 4 adopt an upper section plug-in structure.
