Description

Technical Field

[0001] The utility model relates to the technical field of magnesium smelting equipment, in particular to a central tube top lifting and slag cleaning device and magnesium smelting reduction equipment. Background Art

[0002] Among magnesium smelting processes, the silicothermic method remains the most mature, and the reduction process directly affects the quality of the crude magnesium produced. Currently, the reduction tanks used in the silicothermic reduction process primarily consist of horizontal and vertical tanks. Horizontal tank reduction has been used for many years, and while the process still has some flaws, it is relatively well-established. Vertical tank reduction, on the other hand, is gaining popularity, and while it offers significant advantages over horizontal tank reduction, its process technology still has significant shortcomings and requires further improvement, optimization, and refinement.

[0003] In the vertical tank silicon-thermal magnesium reduction process, the tank is placed vertically within the reduction furnace. After the charge reacts within the tank, gravity is used to drain the slag, significantly reducing deslagging time and improving magnesium smelting efficiency. To deslagging the tank after the reduction furnace reaction is complete, the feed port at the top of the tank is opened, the center drum is lifted using a crane or other equipment, and the slag outlet at the bottom of the tank is opened. The slag is discharged through the outlet under the influence of gravity. Once deslagging is complete, the center drum is returned to the tank.

[0004] This slag discharge method requires that the feed port and the slag discharge port of the vertical tank must be opened at the same time during slag discharge, causing outside air to enter from the slag discharge port below the vertical tank. As the air moves from bottom to top, the air will be mixed with the reduced slag in the tank and sprayed out from the feed port of the vertical tank, making the operating environment above the vertical tank very harsh.

[0005] In addition, during the magnesium reduction reaction, the air vents on the surface of the central tube will be blocked by magnesium slag. After the slag is discharged from the vertical tank, it is necessary to manually clean the discharge port above the vertical tank under high temperature. This operation is not only time-consuming and labor-intensive, but also poses certain safety hazards. Utility Model Content

[0029] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] At present, the slag discharge method of the vertical tank of the magnesium smelting reduction tank is usually to open the feed port above the vertical tank, lift the center tube and open the slag outlet below the vertical tank for slag discharge. In this slag discharge method, outside air will enter the tank body from the slag discharge port below the vertical tank, making the operating environment above the vertical tank very harsh. In addition, during the magnesium reduction reaction process, the air vents on the surface of the center tube will be blocked by magnesium slag. After the slag discharge of the vertical tank is completed, the magnesium slag in the air vents needs to be manually cleaned, which is time-consuming and labor-intensive, and there are certain safety hazards. In this regard, the utility model provides a center tube lifting and slag cleaning device, which can not only improve the slag discharge operating environment, but also reduce the labor intensity of cleaning the slag from the air vents.

[0034] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present invention, a central tube lifting and slag removal device 10 is provided. The central tube lifting and slag removal device 10 includes an equipment platform 11, a central tube lifting mechanism 12, and a central tube vibrating mechanism 13. The central tube lifting mechanism 12 is mounted on the equipment platform 11 and is used to lift the central tube inside the reduction tank body for slag removal. The central tube vibrating mechanism 13 is mounted on the central tube lifting mechanism 12 and is used to generate vibration while the central tube lifting mechanism 12 lifts the central tube for slag removal, thereby causing magnesium slag clogged in the air holes on the side walls of the central tube to fall out of the air holes.

[0035] The above-mentioned center tube lifting and slag cleaning device 10 of the present invention is achieved by setting a center tube lifting mechanism 12 on the equipment platform and installing a center tube vibration mechanism 13 on the center tube lifting mechanism 12; after the magnesium reduction reaction in the vertical tank is completed, it is only necessary to move the center tube lifting and slag cleaning device 10 to the bottom of the center tube, and lift the center tube upward through the center tube lifting mechanism 12, so that the slag discharge port at the lower end of the reduction tank is opened and slag discharge can be carried out. During the slag discharge process, there is no need to open the feed port at the upper end of the reduction tank, which can effectively reduce the outside air from entering the reduction tank through the slag discharge port, so that the feed port of the reduction tank no longer sprays slag, improves the slag discharge operation environment, and can reduce the heat loss in the reduction tank. In addition, the center tube vibration mechanism 13 can vibrate the center tube to remove the magnesium slag blocked in the air vents, which can effectively reduce the labor intensity of slag cleaning, reduce safety hazards, shorten the production cycle, and improve production efficiency.

[0036] See also Figure 1 In some embodiments, the central tube lifting mechanism 12 includes a first lifting mechanism 121, a first support rod 122, and a lifting rod 123. The first lifting mechanism 121 is vertically mounted on the equipment platform 11, one end of the first support rod 122 is connected to the output end of the first lifting mechanism 121, the lifting rod 123 is mounted on the first support rod 122, and the central tube vibration mechanism 13 is mounted on the lifting rod 123. By vertically mounting the first lifting mechanism 121 on the equipment platform 11, the first lifting mechanism 121 can drive the first support rod 122 and the lifting rod 123 to rise and fall together. When the lifting rod 123 rises, it can lift the central tube for slag discharge and vibration cleaning. After the slag discharge and slag cleaning are completed, the first support rod 122 and the lifting rod 123 are lowered, and the central tube is lowered and reset.

[0037] In some embodiments, the center tube vibration mechanism 13 is mounted on an end of the jacking rod 123 away from the first support rod 122, and the end of the center tube vibration mechanism 13 away from the jacking rod 123 is used to contact the center tube. In this configuration, the center tube vibration mechanism 13 is arranged on the end of the jacking rod 123 away from the first support rod 122, so that the center tube vibration mechanism 13 is located between the center tube and the jacking rod 123 during jacking slag removal and vibration slag cleaning. This can better vibrate the center tube, better clean the magnesium slag blocked in the air vents, and further improve the slag cleaning effect.

[0038] It is understandable that the central tube vibration mechanism 13 may also be installed at other positions on the lifting rod 123. In this case, the central tube vibration mechanism 13 can vibrate, driving the lifting rod 123 to vibrate, thereby indirectly causing the central tube to vibrate.

[0039] It should be noted that the first lifting mechanism 121 can be an existing commonly used lifting mechanism. In some embodiments, the first lifting mechanism 121 includes one or more of a chain lifting mechanism, a scissor lift mechanism, a rack and pinion lifting mechanism, a cylinder lifting mechanism, and a hydraulic cylinder lifting mechanism.

[0040] See also Figure 2 In some embodiments, the center tube lifting mechanism 12 includes a second support rod 124 and a second lifting mechanism 125. One end of the second support rod 124 is fixedly mounted on the equipment platform 11, the second lifting mechanism 125 is mounted on the second support rod 124, and the center tube vibrating mechanism 13 is mounted on the second lifting mechanism 125. With this arrangement, during slag discharge, the second support rod 124 remains stationary, the second lifting mechanism 125 mounted on the second support rod 124 lifts the center tube for slag discharge, and the center tube vibrating mechanism 13 mounted on the second lifting mechanism 125 simultaneously vibrates to remove slag.

[0041] In some embodiments, the central cylinder vibration mechanism 13 is connected to the output end of the second lifting mechanism 125, and the end of the central cylinder vibration mechanism 13 away from the second lifting mechanism 125 is used to contact the central cylinder. In this arrangement, the central cylinder vibration mechanism 13 is connected to the output end of the second lifting mechanism 125, so that the central cylinder vibration mechanism 13 is located between the central cylinder and the second lifting mechanism 125 during slag lifting and vibration slag cleaning. This can better vibrate the central cylinder, better clear magnesium slag blocked in the air vents, and further improve the slag cleaning effect.

[0042] It is understood that the central cylinder vibration mechanism 13 does not necessarily need to be connected to the output end of the second lifting mechanism 125, and can also be installed at other locations on the second lifting mechanism 125. In this case, the second lifting mechanism 125 will not drive the central cylinder vibration mechanism 13 to move up and down. In this case, the vibration of the central cylinder vibration mechanism 13 can drive the vibration of the second lifting mechanism 125, thereby indirectly causing the central cylinder to vibrate.

[0043] See also Figure 3 In some embodiments, the central tube lifting mechanism 12 further includes a third lifting mechanism 126, which is vertically mounted on the equipment platform 11. One end of the second support rod 124 is connected to the output end of the third lifting mechanism 126. Specifically, the second support rod 124 is mounted on the third lifting mechanism 126, and the third lifting mechanism 126 can drive the second support rod 124 and the third lifting mechanism 126 to move upward and downward as a whole. Simultaneously, the third lifting mechanism 126 on the second support rod 124 can also move upward and downward.

[0044] It should be noted that both the second lifting mechanism 125 and the third lifting mechanism 126 can be conventional lifting mechanisms. In some embodiments, the second lifting mechanism 125 and the third lifting mechanism 126 each independently include one or more of a chain lifting mechanism, a scissors lifting mechanism, a rack and pinion lifting mechanism, a cylinder lifting mechanism, and a hydraulic cylinder lifting mechanism.

[0045] Similarly, the central cylinder vibration mechanism 13 may also employ existing vibration mechanisms commonly used in the art. In some embodiments, the central cylinder vibration mechanism 13 includes one or more of an ultrasonic vibrator and a vibration motor. It should be noted that the central cylinder vibration mechanism 13 only needs to cause the central cylinder to vibrate slightly to clean the slag from the air vents. The degree of central cylinder vibration can be adjusted by adjusting the amplitude of the vibration generated by the central cylinder vibration mechanism 13.

[0046] In some embodiments, the equipment platform 11 is a movable platform. The use of the movable equipment platform 11 allows the central tube lifting and slag cleaning device 10 to be conveniently moved to the bottom of the central tube when lifting and slag removal and vibration slag cleaning are required, and the central tube lifting and slag cleaning device 10 can be removed after the slag removal and slag cleaning are completed. Furthermore, one central tube lifting and slag cleaning device 10 can be used to sequentially discharge and clean slag in multiple reduction tanks, that is, one central tube lifting and slag cleaning device 10 can be used with multiple reduction tanks, providing greater flexibility.

[0047] See also Figure 4In one embodiment of the present invention, a magnesium smelting reduction device 20 is provided. The magnesium smelting reduction device 20 includes a reduction tank 21 and the central tube lifting and slag cleaning device 10 described above. The reduction tank 21 includes a tank body 211 and a central tube 212. The tank body 211 has a feed port 211a at its upper end and a slag discharge port 211b at its lower end. The central tube 212 is liftably disposed within the tank body 211. A plurality of air holes 212a are provided on the sidewalls of the central tube 212.

[0048] The above-mentioned magnesium smelting reduction equipment 20 is provided with the central tube lifting slag cleaning device 10 of the utility model. After the magnesium reduction reaction in the tank body 211 is completed, the central tube lifting slag cleaning device 10 is moved to the bottom of the central tube 212, and the central tube lifting mechanism 12 is used to lift the central tube 212 upward, so that the slag discharge port 211b at the lower end of the tank body 211 is opened to discharge slag. During the slag discharge process, there is no need to open the feed port 211a at the upper end of the tank body 211, which can effectively reduce the outside air from the slag discharge port 211b entering the tank body 211, so that the feed port 211a of the tank body 211 no longer sprays slag, improves the slag discharge operation environment, and can reduce the heat loss in the tank body 211. The central tube vibration mechanism 13 can vibrate the central tube 212 to remove the magnesium slag blocked in the air vent 212a, which can effectively reduce the labor intensity of slag removal, reduce safety hazards, shorten the production cycle, and improve production efficiency.

[0049] In some embodiments, the magnesium smelting reduction equipment 20 may further include a slag box 22. During the process of lifting and vibrating the central cylinder 212 to remove slag, the slag box 22 may be placed below the slag outlet 211b to collect the magnesium slag falling from the slag outlet 211b.

[0050] The following describes the process of slag removal and vibration slag removal using a central tube jacking and slag cleaning device 10 and a corresponding magnesium smelting reduction device 20 according to an embodiment of the present invention as an example:

[0051] The silicon thermal method vertical tank reduction process is adopted. After the reduction reaction in the tank body 211 is completed, the central tube lifting and slag cleaning device 10 is moved to the bottom of the tank body 211, so that the central tube lifting mechanism 12 is directly below the central tube 212; further, when discharging slag, the first lifting mechanism 121 is started to drive the first support rod 122 and the lifting rod 123 to rise, so that the top of the lifting rod 123 is combined with the bottom end of the central tube 212; after the combination is successful, the first lifting mechanism 121 is continued to be started, so that the lifting rod 123 lifts the central tube 212, the slag discharge port 211b is opened, and the magnesium slag 30 is discharged from the slag discharge port 21 1b is discharged, and the lifting rod 123 stops lifting the central tube 212 when it reaches 0.5 meters. After the magnesium slag in the tank body 211 is discharged, the central tube vibration mechanism 13 is started to vibrate the central tube 212, and the magnesium slag 30 blocked in the air vent 212a is cleared by the vibration of the central tube 212. The central tube vibration mechanism 13 is started and stopped 10 minutes later, and the first lifting mechanism 121 controls the first support rod 122 and the lifting rod 123 to slowly descend, driving the central tube 212 to slowly descend. After the central tube 212 is reset, the central tube lifts the slag cleaning device 10 to go to the next vertical tank.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
