[0002] Red mud is tailings produced during aluminum production. Its mineral composition is complex, primarily containing Al2O3, Fe2O3, SiO2, and other minerals. It is typically highly alkaline and corrosive. On average, 1.0-2.0 tons of red mud are generated for every ton of alumina produced.
[0003] Patent publication number CN116586400A discloses a thermal reaction red mud pretreatment process and a horizontal spiral thermal reactor. The process steps include: S1: performing a muffle preheating treatment on a mixed material in the first calcination zone of a calcination apparatus, controlling the preheating temperature to 600-1000 degrees Celsius; the mixed material includes red mud and a modifying agent; S2: performing a muffle reduction roasting on the material in the second calcination zone of the calcination apparatus, controlling the roasting temperature to 1200-1400 degrees Celsius, to convert the iron oxide in the red mud into ferroferric oxide. The calcination apparatus is a horizontal spiral thermal reactor that can perform a muffle heat treatment on the material, effectively preventing sulfur and nitrogen-containing fumes generated by combustion from contacting the material during heating, causing contamination and forming sulfur- and nitrogen-containing compound impurities.

A baffle 8 is fixed to the inner wall of the kettle body 2. The rotating rod 6 passes through the baffle 8 and fits in the penetration. An auxiliary device is provided on the top of the rotating rod 6 to facilitate the full reaction of the red mud. A feeding device is provided in the kettle body 2 to make the red mud evenly distributed in the kettle body 2. A promotion device is provided above the feeding device to prevent the accumulation of red mud. The auxiliary device includes an extrusion block 91, a transmission block 92, an extrusion plate 93, a connecting spring 94, a rotating block 96, a rotating rod 95, a flip plate 97, a friction wheel 910, an arc block 98, a rotating shaft 99, and a protrusion 91. 1. Transmission spring 913 and breaking up block 912; the extrusion block 91 is fixed to the outer wall of the rotating rod 6, the transmission block 92 passes through the top of the kettle body 2, and is slidably connected at the penetration point, the extrusion plate 93 is fixed to the top of the transmission block 92, one side of the connecting spring 94 is fixed to the top of the kettle body 2, and the other side of the connecting spring 94 is fixed to the bottom of the extrusion plate 93, the rotating rod 95 passes through the feed cover 3, and is rotatably connected at the penetration point, the rotating block 96 is fixed to the end point of the rotating rod 95, the flip plate 97 is fixed to the outer wall of the rotating rod 95, and the side wall of the rotating block 96 is fixed with a Torsion spring, the side of the No. 1 torsion spring away from the rotating block 96 is fixed to the side wall of the feed cover 3, the arc block 98 is fixed to the inner wall of the feed cover 3, the rotating shaft 99 is rotatably installed on the side wall of the flip plate 97, the friction wheel 910 is fixed to the outer wall of the rotating shaft 99, the outside of the friction wheel 910 is in contact with the outer wall of the arc block 98, the protrusion 911 is fixed to the outer wall of the rotating shaft 99, the scattering block 912 is slidably installed on the side wall of the flip plate 97, one side of the transmission spring 913 is fixed to the bottom of the flip plate 97, and the other side of the transmission spring 913 is fixed to the outer wall of the scattering block 912.
[0021] When the rotating rod 6 drives the extrusion block 91 to rotate, the extrusion block 91 squeezes the bottom arc surface of the transmission block 92 back and forth. Through the cooperation of the connecting spring 94, the extrusion plate 93, the rotating rod 95, the rotating block 96 and the first torsion spring, the flip plate 97 can open or close the feed cover 3 back and forth, thereby performing intermittent feeding, solving the problem that the red mud cannot fully react with the reducing agent due to one-time feeding. And when the flip plate 97 is flipping, the friction wheel 910 can move on the arc block 98, so that the friction wheel 910 can rotate under the extrusion force, and through the cooperation of the rotating shaft 99, the protrusion 911 and the transmission spring 913, the multiple groups of breaking rods on the breaking block 912 can break up the red mud that is stuck together, so that the broken up material can easily slide off the flip plate 97, preventing the material from being too large and causing the risk of being blocked in the feed cover 3.
[0022] When this embodiment is working: when it is necessary to reduce the red mud, the red mud and the reducing agent are added to the kettle body 2 through the feed cover 3, and the motor 5 is started to rotate the rotating rod 6, which drives the stirring rod 7 to rotate, and the red mud and the reducing agent are stirred and mixed. When the rotating rod 6 rotates, the extrusion block 91 can be driven to rotate. When the extrusion block 91 rotates to the top of the rotating rod 6, the extrusion block 91 will squeeze the bottom arc surface of the transmission block 92, so that the transmission block 92 will move upward under the extrusion force, and the extrusion plate 93 will move upward. When the extrusion plate 93 moves upward, the extrusion plate 93 can drive the connecting spring 94 to stretch, and the extrusion plate 93 The top will squeeze the bottom of the rotating block 96, so that the rotating block 96 can rotate upward, so that the rotating block 96 drives the rotating rod 95 to rotate, and the flip plate 97 rotates downward, so that the feed cover 3 is opened, and the material is fed into the kettle body 2. When the squeezing block 91 rotates to no longer contact the transmission block 92, the connecting spring 94 is in a stretched state, which causes the connecting spring 94 to drive the squeezing plate 93 to move downward, so that the squeezing plate 93 can squeeze the rotating block 96 to rotate downward for reset, and the rotating rod 95 drives the flip plate 97 to flip upward for reset, thereby blocking the feed cover 3, so that intermittent unloading operation can be performed by opening and closing the flip plate 97. When the flip plate 97 flips, since the center of the arc block 98 and the center of the rotating rod 95 are concentrically arranged, when the flip plate 97 drives the friction wheel 910 to rotate, the friction wheel 910 will move inside the arc block 98. The friction wheel 910 will rotate due to the extrusion force. When the friction wheel 910 rotates, it can drive the rotating shaft 99 to rotate. When the rotating shaft 99 rotates, it can drive the protrusion 911 to rotate. When the protrusion 911 rotates to the top of the rotating shaft 99, the protrusion 911 will hit the scattering block 912. Extrusion can make the scattering block 912 move upward and compress the transmission spring 913. When the scattering block 912 moves upward, the scattering rod fixed on the scattering block 912 can scatter the material on the flip plate 97. Because red mud is generally sticky, it may stick together and form blocks, which is inconvenient for unloading. When the protrusion 911 rotates to stop squeezing the scattering block 912, the transmission spring 913 is in a compressed state, which can make the transmission spring 913 drive the scattering block 912 to reset, so that the scattering block 912 can move back and forth up and down to scatter the material.

The outer wall of the large gear 107 is engaged with the inner side of the gear ring 108, and the scraper 109 is fixed on the side wall of the gear ring 108. The end of the scraper 109 is fitted with the inner side of the kettle body 2. A semicircular arc groove is provided on the side wall of the baffle 8, and the scraper 109 runs through the semicircular arc groove, so that when the gear ring 108 rotates, it can drive the scraper 109 to rotate in a circle in the baffle 8.
[0024] By providing multiple groups of discharge holes on the discharge plate 106, and the number of discharge holes increases from left to right on the discharge plate 106, and the discharge plate 106 is inclined, the material dropped from the feed hood 3 on the discharge plate 106 slides down and falls from the discharge holes of the discharge plate 106 in sequence, so that the material can fall evenly into the kettle body 2, solving the problem of material accumulation in one position of the kettle body 2, which reduces the reaction efficiency. When the transmission block 92 moves upward, the teeth 102 can move on the pinion 103, thereby driving the pinion 103 to rotate, and the pinion 103 drives the disc 104 to rotate. Through the cooperation of the push rod 105, the blanking plate 106 can be shaken up and down, thereby increasing the blanking rate of the blanking plate 106 and preventing the material from sticking to the blanking plate 106 and being difficult to fall off; When the rotating rod 101 rotates, the scraper 109 can be fitted against the inner wall of the upper half of the kettle body 2 and rotate through the cooperation of the large gear 107 and the gear ring 108, so as to scrape off the material splashed on the inner wall of the upper half of the kettle body 2, thereby solving the problem of auxiliary material on the inner wall of the upper half of the kettle body 2 causing insufficient reaction.

[0026] When the scraper 109 rotates, it squeezes the bottom of the transmission column 114. Through the cooperation of the slider 113 and the second torsion spring, the knocking plate 112 can knock the outer wall of the feed cover 3 back and forth, so that the material stuck to the inner wall of the feed cover 3 can fall off quickly, solving the problem that the material sticks to the inner wall of the feed cover 3 and may cause blockage at the feed cover 3. And when the discharge plate 106 moves back and forth, through the cooperation of the inclined block 116, the L-shaped plate 115 and the return spring 117, the toggle rod 119 can toggle the material on the top of the discharge plate 106 back and forth, and toggle the material dropped from the bottom of the feed cover 3, so that the material is evenly distributed on the top of the discharge plate 106, solving the problem of the risk of blockage caused by the accumulation of materials on the discharge plate 106, ensuring the smooth flow of materials and improving the discharge speed.
[0027] When this embodiment works: when the transmission block 92 moves upward, the teeth 102 can rotate on the pinion 103, so that the teeth 102 can drive the pinion 103 to rotate counterclockwise, so that the pinion 103 drives the rotating rod 101 to rotate counterclockwise, and when the rotating rod 101 rotates counterclockwise, the rotating rod 101 drives the disc 104 to rotate counterclockwise, so that the disc 104 pulls the push rod 105 to move downward, so that the push rod 105 pulls the blanking plate 106 to move downward, and when the disc 104 drives the push rod 105 to move upward, it can The push rod 105 can push the blanking plate 106 to move upward, so that when the material falls from the feed cover 3 onto the blanking plate 106, the material is discharged through the discharge hole opened on the blanking plate 106, and the blanking plate 106 shakes up and down back and forth, which can improve the efficiency of the blanking plate 106; and when the rotating rod 101 rotates counterclockwise, the large gear 107 can rotate counterclockwise, so that the large gear 107 drives the gear ring 108 to rotate on the baffle 8, so that the gear ring 108 drives the scraper 109 to scrape off the material attached to the upper half of the kettle body 2; When the scraper 109 rotates to contact the bottom arc surface of the transmission column 114, the bottom of the transmission column 114 will be squeezed and moved upward.

[0028] When the lower plate 106 moves downward, the inclined surface of the L-shaped plate 115 will be squeezed against the inclined surface of the inclined surface block 116, and the L-shaped plate 115 will be subjected to the extrusion force and move outward of the lower plate 106, thereby stretching the return spring 117. When the lower plate 106 moves upward, the inclined surface of the L-shaped plate 115 will not contact the inclined surface of the inclined surface block 116. Because the return spring 117 is in a stretched state, the L-shaped plate 115 can move into the lower plate 106. When the L-shaped plate 115 moves back and forth, it can drive the moving plate 118 to move back and forth, so that the toggle rod 119 moves back and forth on the top of the lower plate 106, which can evenly distribute the materials accumulated on the lower plate 106, facilitating the unloading operation. When the materials react well, the sealing cover 4 can be opened and the reacted materials can be taken out from the kettle body 2.
