Detailed Implementation

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The crude magnesium conveying device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1-3 As shown, the crude magnesium conveying equipment 100 according to an embodiment of the present invention includes an air-cooled conveying device 1, a crystallizer conveying device 2, a crystallizer transfer device 3, a magnesium crushing device 41, a crusher 42, an air-cooled intermediate silo 5, a belt conveyor 6, and an unloading vehicle 7.

[0022] The crystallizer transfer device 3 cooperates with each of the air-cooled conveyor device 1 and the crystallizer conveyor device 2 to transfer the crystallizer on the air-cooled conveyor device 1 to the crystallizer conveyor device. The magnesium crushing device 41 cooperates with the crystallizer conveyor device 2 to remove crude magnesium from the crystallizer. The crusher 42 is located below the crystallizer conveyor device 2 to crush the crude magnesium. The inlet of the air-cooled intermediate silo 5 is connected to the outlet of the crusher 42, and the air-cooled intermediate silo 5 has a cooling air inlet. The belt conveyor 6 cooperates with the outlet of the air-cooled intermediate silo 5. The unloading car 7 is movably mounted on the belt conveyor 6 along the conveying direction of the belt conveyor 6.

[0023] The working process of the crude magnesium conveying device 100 of this application is described below. After the reduction reaction is completed, the crystallizer with crude magnesium attached is removed from the reactor and placed in the air-cooled conveying device 1. The air-cooled conveying device 1 conveys the crystallizer and cools the crystallizer and crude magnesium during the conveying process.

[0024] Subsequently, the crystallizer transfer device 3 transfers the crystallizer from the air-cooled conveyor device 1 to the crystallizer transfer device 3. The crystallizer transfer device 3 then conveys the crystallizer to the area below the magnesium crushing device 41. The magnesium crushing device 41 is used to remove the crude magnesium from the crystallizer. The crude magnesium falls into the crusher 42, where it is crushed to obtain fines.

[0025] Next, the crushed material falls into the air-cooled intermediate silo 5, and cold air is supplied into the air-cooled intermediate silo 5 to cool the crushed material inside. The cooled crushed material is then supplied to the belt conveyor 6. The crushed material is transported by the belt conveyor 6, and the unloading car 7 adds the crushed material on the belt conveyor 6 into the refining crucible 200.

[0026] According to an embodiment of the present invention, the crude magnesium conveying device 100 is equipped with an air-cooled conveying device 1, which provides preliminary cooling to the crystallizer during the conveying process. This not only reduces the cooling burden on the air-cooled intermediate silo 5, but also ensures that the temperature of the crude magnesium scrap is sufficiently low after cooling by the air-cooled intermediate silo 5, preventing the crude magnesium scrap from burning the belt of the belt conveyor 6.

[0027] According to an embodiment of the present invention, the coarse magnesium conveying device 100 can crush coarse magnesium into small pieces by setting a crusher 42, which can not only effectively improve the cooling effect of the coarse magnesium small pieces to prevent the coarse magnesium small pieces from burning the belt of the belt conveyor 6, but also accelerate the cooling speed of the coarse magnesium small pieces to improve the conveying efficiency of the coarse magnesium conveying device 100.

[0028] Moreover, by utilizing the crude magnesium conveying device 100 of the present invention, it is no longer necessary to use a forklift to transfer the crystallizer and crude magnesium, nor is it necessary to use a hook crane or forklift to add crude magnesium into the refining crucible for melting and refining.

[0029] Therefore, the crude magnesium conveying equipment 100 according to the embodiments of the present invention has the advantages of high automation, good process continuity, high conveying efficiency, low manual labor intensity, and good cooling effect.

[0030] like Figures 1-3 As shown, the crude magnesium conveying equipment 100 includes an air-cooled conveying device 1, a crystallizer conveying device 2, a crystallizer transfer device 3, a magnesium crushing device 41, a crusher 42, an air-cooled intermediate silo 5, a belt conveyor 6, and an unloading vehicle 7.

[0031] The air-cooled conveying device 1 includes an air-cooled conveying chamber, a conveyor, a first blower, a first induced draft fan, and a first dust collector. The air-cooled conveying chamber has an air-cooled space, and is equipped with a conveyor outlet and an induced draft fan, both of which are connected to the air-cooled space.

[0032] The conveyor is located within the air-cooled space, with its outlet extending outwards. A first blower is also located within the air-cooled space, positioned opposite the conveyor to supply cool air to the crystallizer and crude magnesium on the conveyor. The inlet of the first induced draft fan is connected to its outlet, and the first dust collector is connected to its outlet.

[0033] For a magnesium smelter with a capacity of 50,000 tons / year (using the Pidgeon process vertical tank), the reduction workshop produces about 7 tons of crude magnesium per hour. Considering that the output of a single reduction tank is 120 kg of crude magnesium, about 60 reduction tanks are used for magnesium output per hour.

[0034] After the reduction reaction is complete, a crane is used to remove the crystallizer with crude magnesium attached from the reactor and place it on a conveyor belt equipped with a metal conveyor belt to prevent it from being damaged by the hot crystallizer. During the conveyor transport of the crystallizer, a first blower supplies cold air to the crystallizer and crude magnesium on the conveyor belt to cool them. The temperature of the crude magnesium is reduced to approximately 300 degrees Celsius. That is, when the crystallizer and crude magnesium leave the conveyor belt (air-cooled conveyor device 1), the temperature of the crude magnesium is approximately 300 degrees Celsius.

[0035] Optionally, there may be multiple first blowers, spaced apart along the conveying direction (length direction) of the conveyor, to more effectively cool the crystallizer and crude magnesium. Each first blower may be located above the conveyor so that each first blower continuously delivers cold air from top to bottom to the crystallizer and crude magnesium on the conveyor.

[0036] While the first blower cools the crude magnesium, the first induced draft fan is activated to draw the heat-exchanged hot air from the air-cooled space. The temperature of the heat-exchanged hot air is approximately 200 degrees Celsius. The first induced draft fan then delivers the hot air to the first dust collector to collect the dust carried by the hot air. The dust-removed hot air can be returned to the regenerative burner of the magnesium reduction furnace as combustion air. The dust can be returned to the refining process (e.g., the batching section) for magnesium recovery.

[0037] Optionally, a surface cooler can be installed between the first induced draft fan and the first dust collector to cool the hot air after heat exchange, thereby preventing the hot air from damaging the first dust collector. The first dust collector can be a baghouse dust collector.

[0038] The air-cooled conveying device 1 realizes both crystallizer conveying and cooling functions. It not only replaces forklift transportation, but also eliminates the need to set up a crude magnesium cooling buffer area, so as to effectively reduce the floor space.

[0039] When the crystallizer reaches the outlet end of the conveyor, it leaves the air-cooled space of the air-cooled conveying device 1, and the crystallizer transfer device 3 transfers the crystallizer to the crystallizer conveying device 2.

[0040] like Figure 1 and Figure 2 As shown, the crystallizer transfer device 3 is located at the outlet end of the air-cooled conveyor device 1. For example, the crystallizer transfer device 3 is located at the outlet end of the conveyor.

[0041] Optionally, the crystallizer transfer device 3 includes a frame, a clamping moving mechanism, and a hydraulic clamp. The clamping moving mechanism is movably mounted on the frame along a first direction and a second direction, with the first direction perpendicular to the second direction. The hydraulic clamp is mounted on the clamping moving mechanism so that the clamping moving mechanism drives the hydraulic clamp to move along the first and second directions. For example, the first direction can be horizontal, and the second direction can be vertical.

[0042] When the crystallizer reaches the outlet of the conveyor, the clamping moving mechanism drives the hydraulic clamp to move to the crystallizer. After the hydraulic clamp picks up the crystallizer, the clamping moving mechanism drives the hydraulic clamp and the crystallizer to move to the crystallizer conveying device 2, so that the crystallizer can be placed in the crystallizer conveying device 2, completing the transfer of the crystallizer.

[0043] The crystallizer conveyor 2 transports the crystallizer to below the magnesium-beating device 41, so as to transport the crystallizer to the magnesium-beating working position. The magnesium-beating device 41 cooperates with the crystallizer conveyor 2 to remove crude magnesium from the crystallizer.

[0044] like Figure 3As shown, the crystallizer conveying device 2 includes a frame 21, a motor 22, a reducer 23, a conveyor chain 24, and a crystallizer stabilizer 25. The motor 22 is mounted on the frame 21, and the conveyor chain 24 is mounted on the frame 21.

[0045] The input end of the reducer 23 is connected to the output end of the motor 22, and the conveyor chain 24 is connected to the output end of the reducer 23, so that the motor 22 drives the conveyor chain 24 to move through the reducer 23. A crystallizer stabilizer 25 is mounted on the conveyor chain 24, and the crystallizer is mounted on the crystallizer stabilizer 25, so that the conveyor chain 24 drives the crystallizer stabilizer 25 and the crystallizer to move. The crystallizer stabilizer 25 cooperates with the magnesium removal device 41, so that the magnesium removal device 41 can be used to remove crude magnesium from the crystallizer.

[0046] Optionally, motor 22 drives the crystallizer stabilizer 25 and the crystallizer to move horizontally via reducer 23 and conveyor chain 24. When the crystallizer stabilizer 25 and the crystallizer move directly under the magnesium removal device 41, motor 22 shuts off to stop the crystallizer stabilizer 25 and the crystallizer from moving. Then, the magnesium removal device 41 acts on the coarse magnesium on the crystallizer to remove the coarse magnesium from the crystallizer. Subsequently, motor 22 restarts to move the next crystallizer directly under the magnesium removal device 41, and the magnesium removal device 41 is used again to remove the coarse magnesium from the crystallizer.

[0047] like Figure 3 As shown, the conveyor chain 24 includes teeth 241, and the crystallizer stabilizer 25 includes a lower flange 251. The lower flange 251 and the teeth 241 cooperate to make the crystallizer stabilizer 25 more stably positioned on the conveyor chain 24, and the conveyor chain 24 more stably drives the crystallizer stabilizer 25 and the crystallizer to move.

[0048] The magnesium removal device 41 can be hydraulically driven to press the crude magnesium adhering to the crystallizer out of the crystallizer. During the separation of crude magnesium, the crystallizer conveyor 2 stops operating so that the crystallizer and crude magnesium are in a stationary state. After the crude magnesium leaves the crystallizer, the crystallizer conveyor 2 continues to operate so that the magnesium removal operation can be performed on the subsequent crystallizers.

[0049] There can be multiple magnesium removal devices 41. Multiple magnesium removal devices 41 are arranged at intervals above the crystallizer conveying device 2 along the conveying direction (length direction) of the crystallizer conveying device 2 so as to perform magnesium removal operations on multiple crystallizers at the same time.

[0050] like Figure 1 and Figure 2 As shown, the crusher 42 is located below the crystallizer conveyor 2, and the crude magnesium separated from the crystallizer falls into the crusher 42. The crusher 42 crushes the crude magnesium into fragments of 50 mm to 100 mm. Optionally, the crusher 42 is a jaw crusher.

[0051] The discharge port of the crusher 42 is connected to the feed port of the air-cooled intermediate silo 5 so that the coarse magnesium crushed material enters the air-cooled intermediate silo 5. The air-cooled intermediate silo 5 has a cooling air inlet, through which cold air enters the air-cooled intermediate silo 5 to cool the coarse magnesium crushed material inside the air-cooled intermediate silo 5.

[0052] Optionally, the cooling air inlet is located at the bottom and / or lower part of the air-cooled intermediate silo to more thoroughly cool the coarse magnesium scrap within the air-cooled intermediate silo 5. Multiple cooling air inlets are provided to more rapidly cool the coarse magnesium scrap within the air-cooled intermediate silo 5. A cooling air outlet is located at the top of the air-cooled intermediate silo to further thoroughly cool the coarse magnesium scrap within the air-cooled intermediate silo 5.

[0053] The crude magnesium conveying equipment also includes a second blower, a second induced draft fan, and a second dust collector. The outlet of the second blower is connected to the cooling air inlet to continuously supply cold air into the air-cooled intermediate silo 5, cooling the crude magnesium fragments to 30-50 degrees Celsius.

[0054] The inlet of the second induced draft fan is connected to the cooling air outlet to draw out the hot air after heat exchange. The second dust collector works in conjunction with the outlet of the second induced draft fan to collect the dust carried by the hot air. The dust-removed hot air can be returned to the regenerative burner of the magnesium reduction furnace as combustion air. The dust can be returned to the refining process (e.g., the batching section) for magnesium recovery. The second dust collector can be a baghouse dust collector.

[0055] The discharge port of the air-cooled intermediate silo is located at the bottom of the air-cooled intermediate silo to facilitate the removal of coarse magnesium fragments from the air-cooled intermediate silo.

[0056] like Figure 1 and Figure 2 As shown, the crude magnesium conveying equipment 100 also includes a vibrating hopper feeder 8, which is located at the bottom of the air-cooled intermediate silo 5. The inlet of the vibrating hopper feeder 8 is matched with the outlet of the air-cooled intermediate silo 5, and the outlet of the vibrating hopper feeder 8 is matched with the belt conveyor 6. Thus, the crushed crude magnesium in the air-cooled intermediate silo 5 is vibrated and fed to the belt conveyor 6 by the vibrating hopper feeder 8.

[0057] like Figure 1 and Figure 2 As shown, the crude magnesium conveying equipment 100 also includes a frame 9, on which the magnesium crushing device 41, the crystallizer conveying device 2, the crusher 42, and the air-cooled intermediate silo 5 are arranged vertically. By setting the frame 9, the magnesium crushing device 41, the crystallizer conveying device 2, the crusher 42, and the air-cooled intermediate silo 5 can be installed more conveniently and more stably, so as to make the structure of the crude magnesium conveying equipment 100 more stable.

[0058] Furthermore, by mounting the magnesium crushing device 41, the crystallizer conveying device 2, the crusher 42, and the air-cooled intermediate chamber 5 onto the frame 9, the structure of the crude magnesium conveying equipment 100 can be made more compact and rational, effectively reducing the space occupied by the crude magnesium conveying equipment 100. (Up and down direction as follows) Figure 1 As shown by arrow A in the diagram.

[0059] like Figure 1 and Figure 2 As shown, the crystallizer transfer device 3 is mounted on the frame 9 and is located above the crystallizer conveying device 2. This not only makes it easier and more stable to install the crystallizer transfer device 3, but also makes the structure of the crude magnesium conveying equipment 100 more compact and reasonable, further reducing the space occupied by the crude magnesium conveying equipment 100.

[0060] Finally, the coarse magnesium scrap is transported by belt conveyor 6, and the scrap is added to the refining crucible 200 by unloading car 7. There can be multiple belt conveyors 6, which are connected in sequence to increase the conveying distance and allow for a more flexible layout of the magnesium refining workshop.

[0061] The unloading car 7 is movably mounted on the belt conveyor 6 along the conveying direction of the belt conveyor 6. The unloading car 7 can move to the feeding position of the refining crucible 200, and the unloading car 7 adds the crude magnesium scrap from the belt conveyor 6 into the refining crucible 200 to complete the feeding operation. The refining crucible 200 melts and refines the crude magnesium scrap.

[0062] The present invention also discloses a magnesium smelting system. The magnesium smelting system according to an embodiment of the present invention includes a crude magnesium conveying device 100 and a plurality of refining crucibles 200. The plurality of refining crucibles 200 are arranged along the conveying direction (length direction) of the belt conveyor 6. A discharge car 7 cooperates with each refining crucible 200 to add the crude magnesium scraps from the belt conveyor 6 into each refining crucible 200.

[0063] Accordingly, the magnesium smelting system according to embodiments of the present invention has advantages such as high degree of automation, good process continuity, high conveying efficiency, low labor intensity, and good cooling effect.

[0064] The present invention also discloses a method for conveying crude magnesium. The crude magnesium conveying method according to embodiments of the present invention is implemented using a crude magnesium conveying device 100. Figure 4 As shown, the crude magnesium conveying method according to an embodiment of the present invention includes: The crystallizer with crude magnesium attached is transferred from the reduction tank to the air-cooled conveying device 1, and the air-cooled conveying device 1 is used to transport and cool the crystallizer and crude magnesium. The crystallizer is transferred from the air-cooled conveying device 1 to the crystallizer conveying device 2 using the crystallizer transfer device 3, and the crystallizer conveying device 2 transports the crystallizer to the area below the magnesium-beating device 41. The crude magnesium is removed from the crystallizer by the magnesium crushing device 41 and falls into the crusher 42 so that the crude magnesium can be crushed by the crusher 42 to obtain the crushed material. The crushed material falls into the air-cooled intermediate silo 5, where it is cooled. The cooled crushed material is then fed to the belt conveyor 6. The crushed material is transported by belt conveyor 6, and the crushed material on belt conveyor 6 is added into refining crucible 200 by unloading car 7.

[0065] The crude magnesium conveying method according to embodiments of the present invention has advantages such as high degree of automation, good process continuity, high conveying efficiency, low labor intensity, and good cooling effect.
