Description

Technical Field

[0001] The invention relates to the technical field of magnesium ingot smelting, and in particular to a charging device and a charging method 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, calcine the dolomite at high temperature in a rotary kiln. The calcined dolomite is called calcined white, and the main components of calcined white are calcium oxide and magnesium oxide.

[0004] Step 2: Calcine white, ferrosilicon and fluorite powder are weighed 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: Push the pellets into the reduction furnace manually. The reduction furnace has several horizontal reduction tanks arranged in upper and lower rows.

[0006] Step 4: After the pellets are filled, a fire baffle and a crystallization barrel are placed in the reduction tank, the tank cover is closed, the interior of the reduction tank is evacuated (absolute pressure <13.3 Pa), the internal temperature of the reduction furnace is heated to about 1250°C, and maintained for 8 to 10 hours. Under the above conditions, the magnesium oxide in the pellets is reduced to magnesium vapor, and the magnesium vapor 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 cover of the reduction tank, take out the crystallization barrel and the fire baffle, press out the magnesium ingot with a magnesium press after cooling, and then refine 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 work is done under high temperature, the working environment is poor and the work risk is high. Therefore, it is necessary to design a loading device that can simultaneously load the upper and lower rows to speed up step 3.

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

[0060] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 used to limit the present invention.

[0061] Example

[0062] See also Figure 1 to Figure 5 The present invention provides a charging device for a magnesium ingot smelting reduction furnace, comprising: a movable base, a guide hopper 1 203, a guide hopper 205, a lifting assembly 204, a charging mechanism 1, and a charging mechanism 2.

[0063] 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 a drive motor 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 a 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.

[0064] The guide hopper 1 203 and the guide hopper 2 205 are arranged at intervals 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 through the bucket frames on both sides. The guide hopper 203 is located at a low position and far away from the reduction furnace, which is not only convenient for manual feeding, 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 be set above the guide hopper 203. The storage bin 201 is connected to the movable base through a hydraulic lifting rod 202 - the storage bin 201 can be lowered in advance to add a sufficient amount of pellet material, and then the storage bin 201 can be raised; when the reduction tank needs to be charged, the valve can be opened to feed the guide hopper 203.

[0065] 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 at the top, which gradually divides into two paths downward.

[0066] The material lifting assembly 204 is arranged on a movable base. One end of the material lifting assembly 204 is located below the material guide hopper 1 203, and the other end extends to the top of the material guide hopper 205, and is used to convey the pelletized material in the material guide hopper 1 203 to the material guide hopper 205. The material lifting assembly 204 can be an existing commercially available material lifting machine (screw type, belt type, etc.), or can also be a Figure 1 to Figure 5The design of the material lifting component 204 includes: a material lifting mounting frame 2042, two material lifting pulleys, and a material lifting conveyor belt 2041. The material lifting mounting frame 2042 is connected to a movable base. The two material lifting pulleys are respectively mounted on the upper and lower ends of the material lifting mounting frame 2042. The material lifting conveyor belt 2041 is sleeved on the material lifting mounting frame 2042 and wraps around the two material lifting pulleys. At least one of the material lifting pulleys is equipped with a driving motor for driving the material lifting pulley and then driving the material lifting conveyor belt 2041. In this way, when the material lifting conveyor belt 2041 moves, the pelletized material in the guide hopper 1 203 can be transported to the guide hopper 2 205.

[0067] Of course, in order to ensure the use effect of the material lifting conveyor belt 2041, a plurality of support wheels 2043 can be arranged at intervals on the material lifting mounting frame 2042 to support and 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 through 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, so that the position of the tensioning wheel 2044 can be adjusted to adjust the tension of the material lifting conveyor belt 2041.

[0068] The first and second charging mechanisms are arranged at intervals along the width direction of the movable base. Referring to the above, the second guide hopper 205 is gradually divided into two paths, and its bottom has two discharge ports: the first discharge port feeds the first charging mechanism, and the second discharge port feeds the second charging mechanism.

[0069] Generally speaking, the first charging mechanism is at a high position, and when charging, it extends into the reduction tank in the upper row, and pushes the material dropped from the first discharge port into the reduction tank in the upper row to realize the charging. The second charging mechanism is at a low position, and when charging, it extends into the reduction tank in the lower row, and pushes the material dropped from the second discharge port into the reduction tank in the lower row to realize the charging.

[0070] Loading mechanism 1 and loading mechanism 2 can be used Figure 1 to Figure 5 Design:

[0071] 1. The loading mechanism includes: a mounting seat 301, a material guide conveyor belt mechanism 309, a feed barrel 307, a hydraulic barrel push rod 308, a push shovel head 306, a hydraulic push rod 305, and at least one hydraulic adjustment rod 302.

[0072] The mounting seat 301 is horizontally arranged, and one end is hinged to the movable base; the hydraulic adjustment rod 302 is longitudinally arranged, and its bottom end is hinged to the movable base, and its top end is hinged to the other end of the mounting seat 301, and is used to adjust the inclination angle of the mounting seat 301. Figure 1Considering the stability, two hydraulic adjustment rods 302 are provided and distributed on both sides of the mounting seat 301, which are extended and retracted synchronously. The hinged end of the mounting seat 301 and the movable base is provided with a mounting shaft 303, so as the hydraulic adjustment rod 302 is extended and retracted, the mounting seat 301 can deflect with the mounting shaft 303 as the center, thereby changing the inclination angle of the mounting seat 301.

[0073] The feed barrel 307, hydraulic push rod 308, push shovel head 306, and hydraulic push rod 305 are all installed on the mounting seat 301, and therefore also follow the change of the tilt angle of the mounting seat 301. The hydraulic push rod 308 is connected to the feed barrel 307, and the feed barrel 307 can be driven to move by the extension of the hydraulic push rod 308. The hydraulic push rod 305 is connected to the push shovel head 306, and the push shovel head 306 can be driven to move by the extension of the hydraulic push rod 305.

[0074] For details, see Figure 6 , the feed barrel 307 is slidably arranged on the mounting seat 301, one end is end A, the other end is end B, and a feed port 1 is arranged 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 and transport the pelletized material dropped from the discharge port 1, 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 is extended, 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, the push shovel head 306 is driven to extend into the feed barrel 307 from the A end of the feed barrel 307, and the pellet material in the feed barrel 307 is pushed into the upper reduction tank from the B end of the feed barrel 307.

[0075] Of course, a feed hopper 310 may be provided between the feed port 1 and the guide conveyor belt mechanism 309 to guide the pellets falling from the feed port 1 to the guide conveyor belt mechanism 309. In addition, considering that the pellets may be mixed with powder, a plurality of filter holes may be provided at the bottom of the feed barrel 307 to filter out the powder contained in the pellets falling into the feed barrel 307. Of course, a feed hopper 304 may be connected below the mounting seat 301 corresponding to the feed barrel 307 to collect the powder filtered out by the feed barrel 307.

[0076] 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 cylinder push rod 408, a second pushing shovel head 406, a second hydraulic pushing rod 405, and at least one second hydraulic adjustment rod 402.

[0077] The second mounting seat 401 is arranged horizontally, and one end is hinged to the movable base; the second hydraulic adjustment rod 402 is arranged longitudinally, and its bottom end is hinged to the movable base, and its top end is hinged to the other end of the second mounting seat 401, and is used to adjust the tilt angle of the second mounting seat 401. Figure 2 Considering the stability, two hydraulic adjustment rods 402 are provided and distributed on both sides of the second mounting seat 401, and they are extended and retracted synchronously. The hinged end of the second mounting seat 401 and the movable base is provided with a second mounting shaft 403, so as the hydraulic adjustment rod 402 is extended and retracted, the second mounting seat 401 can deflect with the second mounting shaft 403 as the center, thereby changing the inclination angle of the second mounting seat 401.

[0078] The feed barrel 2 407, the hydraulic push rod 2 408, the push shovel head 2 406, and the hydraulic push rod 2 405 are all mounted on the mounting seat 2 401, and thus also follow the change of the tilt angle of the mounting seat 2 401. The hydraulic push rod 2 408 is connected to the feed barrel 2 407, and the feed barrel 2 407 can be driven to move by the extension and retraction of the hydraulic push rod 2 408. The hydraulic push rod 2 405 is connected to the push shovel head 2 406, and the push shovel head 2 406 can be driven to move by the extension and retraction of the hydraulic push rod 2 405.

[0079] Specifically, the feed barrel 407 is slidably arranged on the mounting seat 401, one end is the A end, the other end is the B end, and the top is provided with a feed port 2. The material guide conveyor belt mechanism 409 is located between the discharge port 2 and the feed barrel 407. The material guide conveyor belt mechanism 409 is a belt-type transmission device, which is equipped with a motor drive. The material guide conveyor belt mechanism 409 is used to receive and transport the pelletized material dropped from the discharge port 2, and then drop it into the feed barrel 407 through the feed port 2. One end of the hydraulic push rod 408 is fixedly connected to the mounting seat 401, and the other end is connected to the A end of the feed barrel 407. Then, as the hydraulic push rod 408 is extended, the position of the feed barrel 407 can be adjusted so that its B end extends into the reduction tank of the lower row. One end of the hydraulic push rod 405 is fixedly connected to the mounting seat 401, and the other end is connected to the push shovel head 406. Then, as the hydraulic push rod 405 is extended, the push shovel head 406 is driven to extend into the feed barrel 407 from the A end of the feed barrel 407, and the pelletized material in the feed barrel 407 is pushed into the reduction tank in the lower row from the B end of the feed barrel 407.

[0080] Of course, a second feed hopper 410 may be provided between the second feed port and the second material guide conveyor belt mechanism 409 to guide the pellets falling from the second feed port to the second material guide conveyor belt mechanism 409. In addition, considering that the pellets may be mixed with powder, a plurality of filter holes may be provided at the bottom of the second feed barrel 407 to filter out the powder contained in the pellets falling into the second feed barrel 407. Of course, a second feed hopper 404 may be connected below the second feed barrel 407 corresponding to the second mounting seat 401 to collect the powder filtered out by the second feed barrel 407.
