It has the characteristics of high melting point, high temperature resistance, corrosion resistance, etc. It is widely used in ceramics, abrasives, refractory materials, electronic materials and other fields. Alumina powder is produced in the raw material mill section. Bauxite, lime and circulating mother liquor are added to the raw material mill in proportion to grind the raw ore slurry. The raw ore slurry is classified by a hydraulic cyclone. The overflow of the classifier is qualified raw ore slurry, which is sent to the raw ore slurry tank, and then sent to the pre-desiliconization section of the dissolution workshop by a slurry pump. The bottom flow of the classifier returns to the raw material mill. In the last tank of the desiliconization tank, the mother liquor is used to adjust the solid content of the raw ore slurry after desiliconization. The adjusted slurry is sent to the diaphragm pump in the high-pressure pump room. The diaphragm pump is used to send the raw ore slurry to the casing preheater of the dissolution section, and then it is heated by high-pressure new steam.

Both ends of the pipeline group 3 are connected with a first flange 31, and both ends of the preheating pipe are sealed, and both ends of the material pipe are open. The double-layer pipeline group 3 can preheat the alumina slurry in the inner tube through the outer tube, and the first flange 31 facilitates the connection of the pipeline group 3 with the external pipeline, so that the alumina slurry enters the interior of the pipeline group 3.

[0027] The steam pipe group 4 is connected to the front of the pipeline group 3. The steam pipe group 4 includes a vertical pipe 41. The vertical pipe 41 allows steam to flow. The top of the vertical pipe 41 is connected with a short pipe 42. The short pipe 42 facilitates the connection between the steam pipe and the vertical pipe 41. The top of the short pipe 42 and the bottom of the vertical pipe 41 are both connected with a flange pipe 412. The flange pipe 412 facilitates the connection between the steam pipe group 4 and the external steam pipe, and the interior of the short pipe 42 is fixedly connected with a guide plate 421. The guide plate 421 can prevent the chain belt 53 and the second sprocket 54 from being too large to be transmitted. The flange pipe 412 facilitates the connection between the steam and the steam pipe group 4. The guide plate 421 can centrally guide the steam to drive the impeller 51 for transmission. The back of the vertical pipe 41 is evenly spaced with round pipes 43. The round pipes 43 can discharge steam into the interior of the pipeline group 3, and the round pipes 43 are connected to the pipeline group 3. Both ends of the vertical pipe 41 are connected with sprocket mechanisms 5.

[0028] See also Figure 3 and Figure 4 The sprocket mechanism 5 includes an impeller 51 and a second sprocket 54. The impeller 51 can be driven by steam to rotate and transmit blades. A short shaft 511 runs through the inside of the impeller 51. The short shaft 511 is connected to the first sprocket 52, and the junction of the short shaft 511 and the short tube 42 is connected through a sealed bearing. The short shaft 511 can support and install the impeller 51, and the impeller 51 is rotatably connected to the inside of the short tube 42.

[0029] The outside of the impeller 51 is connected to a first sprocket 52, which can transmit the chain belt 53. The second sprocket 54 is connected to the outside of the impeller 51 at equal intervals. The chain belt 53 is connected between the first sprocket 52 and the second sprocket 54, which can transmit the second sprocket 54 to rotate. The second sprocket 54 is meshed with the chain belt 53, and the back of the second sprocket 54 is connected to the vertical pipe 41 through a seat bearing. The second sprocket 54 can be driven by the first sprocket 52 and the chain belt 53. The seat bearing can support the second sprocket 54, and the outside of the vertical pipe 41 is connected to a tensioner 411 at equal intervals.

[0030] The tensioner 411 is connected to the chain belt 53, and the outside of the second sprocket 54 is connected to a vibration mechanism 6. The outside of the second sprocket 54 is also provided with a motor slot, so that the second sprocket 54 can be connected to an external motor. The second sprocket 54 is driven by the motor, and then the driving mode can be switched. The motor drives the second sprocket 54 and can also reversely drive the impeller 51 and the first sprocket 52 to rotate through the chain belt 53, thereby increasing the flow rate of the steam.

[0031] The vibration mechanism 6 includes a tooth frame 61, and first teeth are evenly connected on both sides of the tooth frame 61. Slotted blocks 622 are evenly connected to the front of the vertical tube 41, and a slider 621 is slidably connected inside the slotted block 622. The slider 621 is connected to the tooth frame 61. The slotted block 622 cooperates with the slider 621 to support and guide the tooth frame 61, so that the tooth frame 61 can perform linear reciprocating motion.

[0032] The tooth frame 61 is meshedly connected with a toothed wheel 62 inside, and a second tooth is evenly spacedly connected to the outer top of the toothed wheel 62, so that the toothed wheel 62 drives the toothed frame 61 to reciprocate left and right, and the toothed wheel 62 is connected to the second sprocket 54. The toothed frame 61 is fixedly connected with a hollow column 63 at one end close to the pipe group 3, and a collision block 65 is slidably connected inside the hollow column 63.

[0033] In this scheme, the aluminum oxide powder is first connected to the innermost pipe in the pipe group 3, so that the aluminum oxide powder flows inside the pipe group 3, and the steam is connected to the flange pipe 412, so that the steam circulates inside the vertical pipe 41 and the short pipe 42, and the aluminum oxide powder is preheated by the steam. At the same time, when the steam flows inside the short pipe 42, it passes through the guide plate 421 to drive the impeller 51 to rotate and then drive the first sprocket 52 to rotate, and then drive the second sprocket 54 to rotate through the transmission of the chain belt 53. At the same time, the chain belt 53 will be restricted by the tensioner 411 to prevent the chain belt 53 and the second sprocket 54 from being unable to transmit due to the large wrap angle. When the second sprocket 54 rotates, it drives the toothed wheel 62 to rotate, and then drives the toothed frame 61 to move. Through the cooperation of the hollow column 63, the spring 64 and the impact block 65, the pipe group 3 is rotated to make the pipe group 3 shake, and the aluminum oxide powder inside it is driven to prevent the aluminum oxide powder from only being able to contact the external materials with the steam during preheating.

[0034] When the alumina powder is preheated by steam, the added sprocket mechanism 5 and the vibration mechanism 6 cooperate to knock the alumina powder inside the pipeline group 3, so that the alumina powder is heated evenly and the preheating effect of the alumina powder is improved. At the same time, the sprocket mechanism 5 is driven by steam, and when the alumina powder is preheated by the steam thermal energy, the kinetic energy of the steam is recovered, saving energy loss, and increasing the green environmental protection performance of the device.
