Technical Field
[0001] This utility model belongs to the field of alumina hollow sphere production technology, specifically a raw material mixing device for the production of alumina hollow spheres. Background Technology
[0002] Hollow alumina spheres are hollow spherical particles mainly composed of alumina. They are produced through specific processes, such as electric furnace smelting and blowing technology, to process industrial alumina into hollow spheres. This material is lightweight, high-strength, high-temperature resistant, and corrosion-resistant. The production process of hollow alumina spheres requires mixing the raw materials. According to the patent document CN214810225U, entitled "A Mixing Device for Preparing Hollow Alumina Sphere Bricks," a motor output drives a rotating rod to rotate, which in turn drives a stirring rod to stir the raw materials. Simultaneously, a reciprocating screw rotates. With the cooperation of a sliding groove and a sliding seat, the reciprocating screw and the threaded sleeve are connected, causing the filter screen to move up and down, effectively preventing filter screen clogging. However, the following drawbacks still exist:
[0003] It drives the filter screen to move only through a threaded connection, which makes it difficult for the filter screen to move fully, thus easily leading to poor anti-clogging effect of the filter screen. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example 1, by Figure 1-2 The present invention relates to a raw material mixing device for the production of hollow alumina spheres, comprising a mixing box 1, a feeding hopper 6 fixedly connected to the top of the mixing box 1, a discharging box 5 fixedly connected to the bottom of the mixing box 1, a discharging port 4 at the bottom of the discharging box 5, a box door 7 on the outside of the mixing box 1, and a stirring mechanism 2 on the mixing box 1.
[0026] Specifically, by Figure 3-4 The mixing mechanism 2 includes a V-shaped frame 201 located inside the mixing chamber 1. An installation frame 202 is provided on the inner side of the V-shaped frame 201, and a filter screen 203 is fixedly connected to the inner side of the installation frame 202. Two inner plates 205 are symmetrically fixedly connected inside the mixing chamber 1. The V-shaped frame 201 is located on top of the two inner plates 205. L-shaped round rods 2014 are fixedly connected between the bottom of each inner plate 205 and the mixing chamber 1. L-shaped plates 2015 are movably sleeved on the outer sides of each of the two L-shaped round rods 2014. Two L-shaped plates 2015 are fixed to the outside of the V-shaped frame 201. Return springs 2016 are fixedly connected between each L-shaped plate 2015 and the mixing chamber 1. The two return springs 2016 are respectively sleeved on the outside of two L-shaped round rods 2014. An L-shaped seat 2010 is fixedly connected to the top of the mixing chamber 1. A drive motor 208 is fixedly mounted on the L-shaped seat 2010. A stirring shaft 206 is fixedly connected to the drive motor 208. A rotating shaft 201 is rotatably connected to the L-shaped seat 2010. 1. The bottom end of the rotating shaft 2011 extends into the interior of the mixing chamber 1. An eccentric block 2013 located inside the mixing chamber 1 is fixedly installed on the outside of the rotating shaft 2011. A conveyor belt 209 is connected between the stirring shaft 206 and the rotating shaft 2011. Multiple lower stirring rods 204 are uniformly fixedly connected to the lower outer part of the stirring shaft 206. The lower stirring rods 204 are located inside the V-shaped frame 201. Multiple upper stirring rods 207 are uniformly fixedly connected to the upper outer part of the stirring shaft 206. 7 is located on the outside of the V-shaped frame 201. Two inclined plates 2012 are symmetrically fixedly connected inside the mixing box 1. The two inclined plates 2012 are respectively located above the two inner plates 205, and both inclined plates 2012 are located above the V-shaped frame 201. By setting the inclined plates 2012, it is convenient to guide the raw materials and prevent the raw materials from falling on the top of the inner plate 205. The rotating shaft 2011 passes through one of the inclined plates 2012 and the inner plate 205, and the eccentric block 2013 corresponds to one of the L-shaped plates 2015.
[0027] In operation, the drive motor 208 is first started, which drives the stirring shaft 206 to rotate. The conveyor belt 209 drives the rotating shaft 2011 to rotate, which in turn drives the eccentric block 2013 to rotate and impact one of the L-shaped plates 2015. At the same time, the two L-shaped plates 2015 slide along the two L-shaped round rods 2014 respectively, which then drives the V-shaped frame 201 to reciprocate and drive the filter screen 203 to reciprocate continuously, improving the anti-clogging effect. When the stirring shaft 206 rotates, it drives the upper stirring rod 207 and the lower stirring rod 204 to rotate, finally achieving full mixing of the raw materials.
[0028] Specifically, by Figure 5-6 As shown, a fixing mechanism 3 is provided between the mounting frame 202 and the V-shaped frame 201. The fixing mechanism 3 includes two bottom blocks 301 symmetrically fixed to the bottom of the mounting frame 202. Both bottom blocks 301 penetrate the V-shaped frame 201. Two screws 306 are symmetrically rotatably connected to the outer side of the V-shaped frame 201. A turntable 305 is fixedly connected to the end of each screw 306 away from the V-shaped frame 201. Threaded sleeves 303 are threaded onto the outer side of each screw 306. Insert rods 302 are fixedly connected to the bottom of each threaded sleeve 303. Insert holes 307 are provided on the side of each bottom block 301 that is away from each other. The two insert rods 302 are respectively inserted into the two insert holes 307. Limiting grooves 304 are provided at the bottom of each of the two L-shaped plates 2015. The two threaded sleeves 303 are slidably connected to the two limiting grooves 304 respectively.
[0029] In use, first open the box door 7, then rotate the two turntables 305 to drive the two screws 306 to rotate, and drive the two screw sleeves 303 to slide along the two limiting grooves 304 respectively. At the same time, the two insert rods 302 move away from each other until the two insert rods 302 are disengaged from the two insertion holes 307 respectively, releasing the fixation between the two bottom blocks 301 and the V-shaped frame 201. Then, remove the mounting frame 202 and the filter screen 203 from the mixing box 1. Finally, clean or replace the filter screen 203.
