Description

Technical Field

[0001] This utility model belongs to the field of alumina dehydration technology, and in particular relates to filters for alumina production. Background Technology

[0002] Alumina dehydration is a crucial step in bauxite production. After a series of processes such as dissolution and decomposition, bauxite needs to have its moisture removed from the alumina to obtain a high-quality alumina product.

[0003] In the dehydration process of alumina, diatomaceous earth is usually added as a dehydrating agent. However, diatomaceous earth particles are small and have a porous structure, so the best dehydration effect can only be achieved by thoroughly and evenly mixing diatomaceous earth with alumina. In actual production, diatomaceous earth and alumina are often added simultaneously and then directly stirred, which makes it difficult to achieve the desired mixing effect. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to the following: Figures 1 to 4 This utility model provides a filter for alumina production, the filter comprising:

[0030] A support frame 101 is provided, on which a feeding mechanism 2 is installed, and a filtering mechanism 3 is installed inside the support frame 101. The feeding mechanism 2 includes a fixed body 201, within which a motor 202 is installed. The motor 202 is connected to the fixed body 201 and its position is fixed. The output shaft of the motor 202 is fixedly connected to a rotating shaft 203 via a coupling. A drive wheel 204 is fixedly connected to the rotating shaft 203, and a belt 205 is driven through the drive wheel 204. A driven wheel 206 is driven through the end of the belt 205 away from the drive wheel 204. Thus, the motor 202 connects to the rotating shaft 203 and drives the rotating shaft 203 to rotate. A stirring shaft 207 is fixedly connected to the driven wheel 206. A lever 208 is fixedly connected to the outer surface of the mixing shaft 207. A platform 209 is fixedly connected to the outer surface of the support frame 101. A discharge bucket 210 is slidably connected to the inner wall of the platform 209. Thus, the platform 209 connects to the discharge bucket 210 and provides support for it. A mounting base 211 is fixedly connected to the outer surface of the support frame 101. A baffle 212 is slidably connected inside the mounting base 211. A guide rod 213 is fixedly connected to the outer surface of the baffle 212. A spring 214 is connected to the baffle 212. The baffle 212 compresses the spring 214 during movement.

[0031] Obviously, the filter for alumina production provided in this embodiment of the invention uses a stirring shaft 207 to drive a lever 208 to rotate. During rotation, the lever 208 actuates the baffle 212, causing the baffle 212 to move the guide rod 213 towards the spring 214. This compression of the spring 214 opens the bottom of the discharge bucket 210, allowing diatomaceous earth to fall into the alumina. In this way, diatomaceous earth is gradually added to the alumina while stirring, resulting in a more uniform mixture. The uniformly mixed diatomaceous earth can better contact the moisture in the alumina slurry, allowing the moisture to separate from the alumina slurry more quickly.

[0032] Please refer to further details. Figure 2 , Figure 3 and Figure 4In a further embodiment of this application, the bottom of the fixed body 201 is fixedly connected to the top of the support frame 101, the rotating shaft 203 is rotatably connected to the support frame 101, the stirring shaft 207 is rotatably connected to the support frame 101, and the top of the baffle 212 contacts the bottom of the discharge bucket 210. Clearly, the stirring shaft 207 is connected to the support frame 101, and the support frame 101 restricts the position of the stirring shaft 207. The guide rod 213 is slidably connected to the mounting base 211, and the end of the spring 214 away from the baffle 212 is fixedly connected to the mounting base 211. The inner side of the spring 214 is sleeved with the outer surface of the guide rod 213. Thus, the guide rod 213 is connected via the spring 214, and the guide rod 213 restricts the movement trajectory of the spring 214.

[0033] Please refer to the following: Figure 1 , Figure 5 , Figure 6 and Figure 7 In a further embodiment of this application, the filtration mechanism 3 includes a fixed platform 301 fixedly connected to the support frame 101, a stirring tank 302 fixedly connected inside the fixed platform 301, a heating coil 303 fixedly connected to the outer surface of the stirring tank 302, and a stirring blade 304 fixedly connected to the stirring shaft 207. Thus, the heating coil 303 is connected to the stirring tank 302, and the heating coil 303 can heat the inside of the stirring tank 302. In addition, a discharge port 305 is provided inside the stirring tank 302, and a cover 306 is threadedly connected to the outer surface of the discharge port 305. A mounting frame 307 is slidably connected inside the support frame 101, and a connecting block 308 is fixedly connected to the outer surface of the mounting frame 307. Thus, the mounting frame 307 is connected to the support frame 101, and the mounting frame 307 can slide inside the support frame 101.

[0034] Optionally, four connecting blocks 308 are provided, and bolts 309 are threadedly connected to the inner wall of the connecting blocks 308. The bolts 309 are threadedly connected to the support frame 101 so as to connect the support frame 101 through the bolts 309 to fix the mounting frame 307.

[0035] Please refer to further information. Figure 6 In a further embodiment of this application, a filter plate 310 is fixedly connected to the inner wall of the mounting frame 307, and a flip cover 311 is rotatably connected to the support frame 101. A handle 312 is fixedly connected to the outer surface of the flip cover 311. Thus, by connecting the flip cover 311 to the handle 312, the flip cover 311 can be rotated within the support frame 101 via the handle 312. Furthermore, a sliding groove 313 is provided inside the support frame 101, and a sliding strip 314 is slidably connected to the inner wall of the sliding groove 313. A collection box 315 is fixedly connected to the top of the sliding strip 314, and the collection box 315 is slidably connected to the support frame 101. Thus, the collection box 315 can slide within the sliding groove 313 by connecting the sliding strip 314 to the sliding groove 313.

[0036] In light of the specific content of the above embodiments, one specific application of this application is as follows:

[0037] When the equipment is needed, the diatomaceous earth is placed into the discharge bin 210, and then the motor 202 is started. The motor 202 causes the rotating shaft 203 to rotate, which in turn drives the drive wheel 204 to rotate. The drive wheel 204 then drives the driven wheel 206 to rotate via the belt 205, which in turn drives the stirring shaft 207 to rotate. The rotation of the stirring shaft 207 drives the actuating rod 208 to rotate. During this rotation, the actuating rod 208 actuates the baffle 212, causing the baffle 212 to move the guide rod 213 towards the spring 214. This compression of the spring 214 opens the bottom of the discharge bin 210, allowing the diatomaceous earth to fall out. When the actuating rod 208 disengages from the baffle 212, the spring 214 returns to its original position, causing the bottom of the discharge bin 210 to close again. Under such conditions, diatomaceous earth can be gradually added to alumina, making the two mix more evenly. The evenly mixed diatomaceous earth can better contact the water in the alumina slurry, allowing the water to separate from the alumina slurry more quickly.

[0038] Based on this, the heating coil 303 heats the mixing tank 302, further accelerating the removal of moisture from the alumina. Next, after processing, the cover 306 is unscrewed from the discharge port 305. At this point, the alumina and diatomaceous earth fall together into the mounting frame 307, where they are filtered by the filter plate 310. The alumina continues to fall into the collection box 315, while the diatomaceous earth remains on the filter plate 310. After filtration, the bolt 309 can be unscrewed from the connecting block 308, and the mounting frame 307 can be removed from the support frame 101 to recycle the diatomaceous earth.

[0039] In this way, diatomaceous earth can be filtered and recycled after processing. After proper cleaning and reprocessing, the recycled diatomaceous earth can still maintain good filtration performance, ensuring the effectiveness of diatomaceous earth recycling. Finally, by rotating the handle 312 to turn the flip cover 311 and opening the support frame 101, the collection box 315 can be pulled out from the support frame 101 to collect the alumina inside the collection box 315.
