Description

Technical Field

[0001] The utility model relates to the technical field of magnesium ingot smelting, in particular to a charging device for a magnesium ingot smelting reduction furnace. Background Art

[0002] The existing magnesium ingot smelting process mainly includes:

[0003] Step 1: Using dolomite as the main raw material, calcining the dolomite in a rotary kiln at high temperature. The calcined dolomite is called calcined white, and its main components are calcium oxide and magnesium oxide.

[0004] Step 2: Calcined silicon, ferrosilicon and fluorite powder are measured and mixed evenly, wherein ferrosilicon is a reducing agent and fluorite is a catalyst, and the powders are ground and pressed into pellets.

[0005] Step 3: Manually push the pellets into the reduction furnace, which has several horizontal reduction tanks arranged in rows.

[0006] Step 4: After the pellets are filled, a fire baffle and a crystallization barrel are placed in the reduction tank, the tank lid is closed, and the interior of the reduction tank is evacuated (absolute pressure <13.3 Pa). The internal temperature of the reduction furnace is heated to approximately 1250°C and maintained for 8 to 10 hours. Under the above conditions, the magnesium oxide in the pellets is reduced to magnesium vapor, which forms crystalline magnesium, also known as crude magnesium, in the condensation crystallization barrel at the front end of the reduction tank.

[0007] Step 5: Destroy the vacuum, open the reduction tank cover, take out the crystallization barrel and fire baffle, and press out the magnesium ingot with a magnesium press after cooling. Then, refine it with flux, let it stand, and cast it to produce a commercial magnesium ingot.

[0008] Step 6: After the reduction slag in the reduction tank is removed, a production cycle is completed and the process returns to step 3 to reload the pellets.

[0009] The existing step 3 uses manual labor to shovel the pellets into the reduction tank multiple times, which has a low degree of mechanization, high labor intensity, and low loading efficiency. In addition, since the operation is carried out under high temperature, the working environment is poor and the work risk is high. Therefore, it is necessary to design a loading equipment that can simultaneously load the pellets from top to bottom to speed up step 3.

[0010] In addition, the inventor also found that the reduction tanks arranged in the upper and lower rows may have some angular displacement in position due to being subjected to long-term high-temperature working conditions of 1250°C, so this impact was also taken into consideration when designing the loading equipment.

[0047] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example

[0049] See Figures 1 to 5 The utility model provides a charging device for a magnesium ingot smelting reduction furnace, comprising: a movable base, a first guide hopper 203, a second guide hopper 205, a material lifting component 204, a first charging mechanism, and a second charging mechanism.

[0050] The movable base is used to drive the entire device to move. The movable base carries the entire device and can be designed to include: a base frame 101, and four base wheels 101. Taking weight factors into consideration, the base frame 101 can be welded and constructed using high-strength rods such as steel, and reinforcements can be appropriately added at the joints. The four base wheels 101 are installed at the bottom of the base frame 101 and form a rectangular four-point distribution, which makes it easier to disperse the force. Of course, the four base wheels 101 can be equipped with drive motors to drive their rotation to achieve free movement. You can also use Figure 3 In this way, a guide rail 102 is installed in front of the reduction furnace, and a track wheel is used as the base wheel 101, so that the base wheel 101 moves on the guide rail 102: when loading, it can be moved along the guide rail 102 to the front of the reduction tank to be loaded.

[0051] The guide hopper 1 203 and the guide hopper 2 205 are spaced apart along the length direction of the movable base. The guide hopper 1 203 is at a low position and is located at one end of the movable base. Figure 1 The guide hopper 203 is connected to the movable base via hopper brackets on both sides. The guide hopper 203 is located low and far from the reduction furnace, which not only facilitates manual refilling but also effectively prevents workers from being too close to the heat source. Of course, a storage bin 201 with a valve at the bottom can also be installed above the guide hopper 203. The storage bin 201 is connected to the movable base via a hydraulic lifting rod 202. The storage bin 201 can be lowered in advance to add a sufficient amount of pellet material, and then raised again. When the reduction tank needs to be charged, the valve is opened to refill the guide hopper 203.

[0052] The guide hopper 205 is at a high position and is located above the middle of the movable base. Figure 2 The second guide hopper 205 is also connected to the movable base through a frame, and has a larger inlet on the top, which gradually divides into two paths downward.

[0053] The lifting assembly 204 is set on a movable base. One end of the lifting assembly 204 is located below the guide hopper 1 203 and the other end extends above the guide hopper 2 205, and is used to transport the pellets in the guide hopper 1 203 to the guide hopper 2 205. The lifting assembly 204 can be an existing commercially available lifting machine (screw type, belt type, etc.), or it can be a Figures 1 to 5 The lifting assembly 204 includes a lifting frame 2042, two lifting pulleys, and a lifting conveyor belt 2041. The lifting frame 2042 is connected to a movable base. The two lifting pulleys are mounted on the upper and lower ends of the lifting frame 2042, respectively. The lifting conveyor belt 2041 is mounted on the lifting frame 2042 and surrounds the two lifting pulleys. At least one of the lifting pulleys is equipped with a drive motor, which drives the lifting pulley and thus drives the lifting conveyor belt 2041. As the lifting conveyor belt 2041 moves, it transports the pellets in the first guide hopper 203 to the second guide hopper 205.

[0054] Of course, to ensure the effective use of the material lifting conveyor belt 2041, a number of support wheels 2043 can be installed at intervals on the material lifting mounting frame 2042 to support the material lifting conveyor belt 2041 from the inside. A tensioning wheel 2044 can also be installed on the material lifting mounting frame 2042 via an adjustable wheel frame; the installation depth of the adjustable wheel frame and the material lifting mounting frame 2042 can be adjusted according to actual conditions, thereby making the position of the tensioning wheel 2044 adjustable to adjust the tension of the material lifting conveyor belt 2041.

[0055] The first and second feeding mechanisms are spaced apart along the width direction of the movable base. Referring to the above, the second guide hopper 205 gradually splits into two paths, and has two discharge ports at its bottom: one discharge port feeds the first feeding mechanism, and the other discharge port feeds the second feeding mechanism.

[0056] Generally speaking, the first charging mechanism is in a high position, and when charging, it extends into the upper row of reduction tanks and pushes the material dropped from the first discharge port into the upper row of reduction tanks to achieve loading. The second charging mechanism is in a low position, and when charging, it extends into the lower row of reduction tanks and pushes the material dropped from the second discharge port into the lower row of reduction tanks to achieve loading.

[0057] Loading mechanism 1 and loading mechanism 2 can be used Figures 1 to 5 Design:

[0058] 1. The loading mechanism includes: a mounting base 301, a material guide conveyor belt mechanism 309, a feed barrel 307, a hydraulic push barrel rod 308, a push shovel head 306, a hydraulic push rod 305, and at least one hydraulic adjustment rod 302.

[0059] The mounting seat 1 301 is arranged horizontally, with one end hinged to the movable base; the hydraulic adjustment rod 1 302 is arranged longitudinally, with its bottom end hinged to the movable base and its top end hinged to the other end of the mounting seat 1 301, for adjusting the tilt angle of the mounting seat 1 301. Figure 1 For stability, two hydraulic adjustment rods 302 are provided, one on each side of the mounting base 301, extending and retracting synchronously. A mounting axis 303 is provided at the hinged end of the mounting base 301 and the movable base. As the hydraulic adjustment rods 302 extend and retract, the mounting base 301 rotates about the mounting axis 303, thereby changing its tilt angle.

[0060] The feed barrel 307, hydraulic push rod 308, push shovel head 306, and hydraulic push rod 305 are all mounted on the mounting base 301 and therefore follow the tilt angle of the mounting base 301. The hydraulic push rod 308 is connected to the feed barrel 307, and its extension and retraction can drive the feed barrel 307 to move. The hydraulic push rod 305 is connected to the push shovel head 306, and its extension and retraction can drive the push shovel head 306 to move.

[0061] For details, see Figure 6 The feed barrel 307 is slidably mounted on the mounting seat 301, with one end being end A and the other end being end B, and a feed port 1 being provided on the top. The material guide conveyor belt mechanism 309 is located between the discharge port 1 and the feed barrel 307. The material guide conveyor belt mechanism 309 is a belt-type transmission device, which is equipped with a motor drive. The material guide conveyor belt mechanism 309 is used to receive the pelletized material dropped from the discharge port 1 and transport it, and then drop it into the feed barrel 307 through the feed port 1. One end of the hydraulic push rod 308 is fixedly connected to the mounting seat 301, and the other end is connected to the A end of the feed barrel 307. Then, as the hydraulic push rod 308 extends, the position of the feed barrel 307 can be adjusted so that its B end extends into the reduction tank in the upper row. One end of the hydraulic push rod 305 is fixedly connected to the mounting seat 301, and the other end is connected to the push shovel head 306. Then, as the hydraulic push rod 305 extends, it drives the push shovel head 306 to extend into the feed barrel 307 from the A end of the feed barrel 307, and pushes the pellets in the feed barrel 307 from the B end of the feed barrel 307 into the upper reduction tank.

[0062] Of course, a feed hopper 310 can also be provided between the discharge port 1 and the guide conveyor belt mechanism 309 to direct the pellets falling from the discharge port 1 to the guide conveyor belt mechanism 309. Furthermore, considering that the pellets may be mixed with powder, a plurality of filter holes can be provided at the bottom of the feed barrel 307 to filter out the powder contained in the pellets that fall into the feed barrel 307. Of course, a receiving hopper 304 can also be connected below the mounting base 301 corresponding to the feed barrel 307 to collect the powder filtered out by the feed barrel 307.

[0063] 2. The second loading mechanism includes: a second mounting seat 401, a second material guide conveyor belt mechanism 409, a second feeding cylinder 407, a second hydraulic pushing cylinder rod 408, a second pushing shovel head 406, a second hydraulic pushing rod 405, and at least one second hydraulic adjusting rod 402.

[0064] The second mounting base 401 is arranged horizontally, with one end hinged to the movable base; the second hydraulic adjustment rod 402 is arranged longitudinally, with its bottom end hinged to the movable base and its top end hinged to the other end of the second mounting base 401, for adjusting the tilt angle of the second mounting base 401. Figure 2 For stability, two hydraulic adjustment rods 402 are provided, one on each side of the second mounting base 401, allowing for simultaneous extension and retraction. A second mounting axis 403 is provided at the hinged end of the second mounting base 401 and the movable base. As the hydraulic adjustment rods 402 extend or retract, the second mounting base 401 rotates about the second mounting axis 403, thereby changing its tilt angle.

[0065] Feed barrel 2 407, hydraulic push rod 2 408, push shovel head 2 406, and hydraulic push rod 2 405 are all mounted on mounting base 2 401 and therefore follow the tilt angle of mounting base 2 401. Hydraulic push rod 2 408 is connected to feed barrel 2 407, and its extension and retraction can drive feed barrel 2 407 to move. Hydraulic push rod 2 405 is connected to push shovel head 2 406, and its extension and retraction can drive push shovel head 2 406 to move.

[0066] Specifically, feed barrel 2 407 is slidably mounted on mounting base 2 401 , with one end being end A and the other end being end B, and a feed port 2 being provided at the top. A material guide conveyor belt mechanism 2 409 is located between discharge port 2 and feed barrel 2 407 . Material guide conveyor belt mechanism 2 409 is a belt-type transmission device equipped with a motor drive. Material guide conveyor belt mechanism 2 409 is used to receive and transport the pelletized material that falls from discharge port 2, and then the pelletized material falls into feed barrel 2 407 through feed port 2. One end of hydraulic push rod 2 408 is fixedly connected to mounting base 2 401 , and the other end is connected to end A of feed barrel 2 407 . As hydraulic push rod 2 408 extends, the position of feed barrel 2 407 can be adjusted so that its end B extends into the reduction tank in the lower row. One end of hydraulic push rod 2 405 is fixedly connected to mounting base 2 401 , and the other end is connected to push shovel head 2 406 . Then, as the hydraulic pushing rod 405 extends, it drives the pushing shovel head 406 to extend into the feeding barrel 407 from the A end of the feeding barrel 407, and pushes the pellets in the feeding barrel 407 from the B end of the feeding barrel 407 into the reduction tank in the lower row.

[0067] Of course, a second feed hopper 410 can also be provided between the second feed port and the second guide conveyor mechanism 409 to direct the pellets falling from the second feed port to the second guide conveyor mechanism 409. Furthermore, considering that the pellets may be mixed with powder, a plurality of filter holes can be provided at the bottom of the second feed barrel 407 to filter out the powder contained in the pellets that fall into the second feed barrel 407. Of course, a second receiving hopper 404 can also be connected below the second mounting base 401 corresponding to the second feed barrel 407 to collect the powder filtered out by the second feed barrel 407.

[0068] In general, the method for charging using the charging device for the magnesium ingot smelting reduction furnace is as follows:

[0069] Step 1: Move the entire device to the front of the reduction furnace via the movable base and face the reduction tank that needs to be loaded.

[0070] Step 2: Adjust the extension and contraction of the hydraulic adjustment rod 302 and change the tilt angle of the mounting base 301 so that the feed cylinder 307 is aligned with the upper row of reduction tanks (referred to as tank 1);

[0071] Adjust the extension and contraction of the second hydraulic regulating rod 402 and change the tilt angle of the second mounting seat 401 so that the second feed barrel 407 is aligned with the reduction tank in the lower row (referred to as tank 2).

[0072] Step 3: Control the hydraulic push rod 308 to extend so that the B end of the feed cylinder 307 extends into the upper reduction tank (i.e., tank 1);

[0073] The hydraulic push cylinder rod 2 408 is controlled to extend so that the B end of the feed cylinder 2 407 extends into the reduction tank (i.e. tank 2) in the lower row.

[0074] Generally, the extension amount of the feed barrel 307 is controlled at 300-400 mm, ensuring that a part of the feed port is exposed to the outside so that the material guide conveyor belt mechanism 309 can drop the material into the feed barrel 307; the extension amount of the feed barrel 407 is controlled at 300-400 mm, ensuring that a part of the feed port is exposed to the outside so that the material guide conveyor belt mechanism 409 can drop the material into the feed barrel 407.

[0075] Step 4: Start the material lifting component 204 to transport the pelletized material in the guide hopper 1 203 to the guide hopper 2 205 and replenish the guide hopper 1 203 in time;

[0076] The charging mechanism 1 is operated cyclically until the upper reduction tank (i.e., tank 1) is fully loaded. Each round of operation of the charging mechanism 1 includes:

[0077] S411, start the material guide conveyor belt mechanism 309 to feed material into the feeding barrel 307;

[0078] S412, controlling the hydraulic push rod 305 to extend, and carrying the push shovel head 306 to extend into the feed barrel 307 from the A end of the feed barrel 307, and push the pellets in the feed barrel 307 from the B end of the feed barrel 307 into the upper row of reduction tanks (i.e., tank 1);

[0079] S413, controlling the hydraulic push rod 305 to shorten so that the push shovel head 306 exits the feed barrel 307;

[0080] The charging mechanism 2 is operated cyclically until the charging of the reduction tank in the lower row (i.e., tank 2) is completed. Each round of operation of the charging mechanism 2 includes:

[0083] S423, controlling the second hydraulic push rod 405 to shorten so that the second push shovel head 406 can withdraw from the second feed barrel 407.

[0084] It should be noted that:

[0085] In S412, the pushing shovel head 306 can also accelerate the filtration of the powder in the feeding barrel 307 when pushing the material;

[0086] In S422, the second pushing shovel head 406 can also accelerate the filtering of the powder in the second feeding barrel 407 when pushing the material.

[0087] Step 5: Control the hydraulic cylinder push rod 308 to shorten, so that the feed cylinder 307 exits the upper row of reduction tanks (i.e., tank 1);

[0088] The hydraulic push cylinder rod 2 408 is controlled to shorten so that the feed cylinder 2 407 exits the reduction tank (i.e. tank 2) in the lower row.
