Description

Technical Field

[0001] The invention relates to the technical field of rutile preparation, and specifically relates to a calcined air-cooled discharging device for transition metal-doped rutile. Background Art

[0002] Rutile powder is one of the main minerals containing titanium (Ti). It is a tetragonal crystal system, often with a perfect tetragonal columnar or needle-shaped crystal shape. Rutile (TiO2) single crystals are used to make spectroscopic devices and filter devices, and play an irreplaceable role in modern optical communications such as optical isolators and optical circulators. After calcination, transition metals can be used as catalysts to catalyze important chemical reactions. Research on the growth technology of transition metal-doped rutile single crystals based on induction heating. The target crystals screened by theoretical calculations are used as the research object to achieve the growth of rutile crystals. After the transition metal-doped rutile is calcined, air cooling is required to achieve discharging. For example, the Chinese utility model patent with patent application number "CN202223247260.8" provides a rotary cooler for cooling synthetic rutile calcined materials. In the device, the cooling component includes two cooling shells, which are respectively located on the front and back of the rotary drum body. The left side of the cooling shell is connected to an air inlet pipe, and the right side is connected to an air outlet pipe. Air can be discharged into or out of the interior of the cooling shell through the air inlet pipe and the air outlet pipe, so as to quickly cool the calcined materials inside the rotary drum body.

[0003] The disadvantage of the device is that since there is no mechanism inside the cooling shell that can change the direction of air flow, the air enters from the air inlet pipe on the left and is directly discharged from the air outlet pipe on the right. In other words, the air at the top of the cooling shell flows more easily, while the air at the bottom of the cooling shell does not flow easily, resulting in a difference in the heat absorption capacity of the top and bottom of the cooling shell, which reduces the efficiency of cooling the calcined material inside the drum body.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1-20 The present invention provides a technical solution: a calcined air-cooled discharging device for transition metal-doped rutile, comprising a rotating drum 1 and an air-cooling assembly 2, the air-cooling assembly 2 comprising an air-cooling sleeve 21 and a plurality of air-guiding assemblies 22, the air-cooling sleeve 21 is sleeved in the middle of the outer surface of the rotating drum 1, the air-guiding assembly 22 is arranged inside the air-cooling sleeve 21, the air-guiding assembly 22 comprises an annular air-guiding plate 221, a spiral air duct 23 is formed between the inner wall of the air-cooling sleeve 21 and the plurality of annular air-guiding plates 221, and a first vent 211 and a second vent 212 are respectively arranged at both ends of the side wall of the air-cooling sleeve 21. When the present invention is used, the calcined material of transition metal-doped rutile is placed in the rotating drum 1, and then cold air is transported into the first vent 211, the cold air will enter the interior of the air-cooling sleeve 21 through the first vent 211, and move along the spiral air duct 23, and finally be discharged through the second vent 212. Since the spiral air duct 23 allows cold air to pass through various positions inside the air cooling sleeve 21 , the heat absorption capacity of various positions of the air cooling sleeve 21 can be kept consistent, thereby improving the efficiency of cooling the calcined material inside the drum.

[0044] See also Figure 1-5 In the present invention, the air-cooling sleeve 21 is composed of an inner ring, an outer ring and two blocking plates. The inner ring fits the outer surface of the drum 1, and the drum 1 can slide along the inner surface of the inner ring, so the drum 1 can rotate freely. The present invention also includes an assembly frame 3 and a wind-driven component 4, and the output end of the wind-driven component 4 is connected to the drum 1 for driving the drum 1 to rotate. The air-cooling sleeve 21 and the wind-driven component 4 are both fixedly connected to the assembly frame 3, so the air-cooling sleeve 21 and the wind-driven component 4 will not move at will. The two ends of the drum 1 are mounted on two support seats at the bottom of the assembly frame 3, and the support seats can provide support for the drum 1. The drum 1 is rotatably connected to the support seat. When the drum 1 rotates, the calcined rutile inside the drum 1 can be prevented from piling up, further increasing the efficiency of cooling.

[0045] See also Figure 1-3 and Figure 15-16The wind-driven assembly 4 includes a first blower 41, a first pipe 42, a first air-gathering ring 43, a second pipe 44, and a plurality of first transmission assemblies 45. The side walls of the first air-gathering ring 43 are provided with a third vent 432 and a fourth vent 433, respectively. The first blower 41 can deliver cold air into the first vent 211 through the first pipe 42. After the air that has absorbed heat is discharged through the second vent 212, it can enter the third vent 432 through the second pipe 44, and then enter the first air-gathering cavity 431 in the first air-gathering ring 43. The first transmission assembly 45 includes a force-bearing plate 451, which is fixedly connected to the rotating drum 1. At this time, the air will push the plurality of force-bearing plates 451 to rotate continuously, thereby driving the rotating drum 1 to rotate. The force-bearing plates 451 and the rotating drum 1 both slide along the inner wall of the first air-gathering ring 43. During the rotation of the plurality of force-bearing plates 451 , the air in the first air collecting chamber 431 can be discharged through the fourth vent 433 , thereby preventing the air pressure in the first air collecting chamber 431 from being too high.

[0046] Embodiment 2

[0047] Based on Example 1, please refer to Figure 1-9 The wind guide assembly 22 also includes a wind force enhancement assembly 222. Each annular wind guide plate 221 is provided with a notch 2211. The notches 2211 are spirally distributed, and the wind force enhancement assemblies 222 correspond to the positions of the notches 2211. The wind force enhancement assembly 222 is arranged on the path of the air duct 23. When the air passes through the wind enhancement assembly 222, the speed can be increased, ensuring that the air can generate sufficient thrust to drive the force-bearing plate 451 to rotate after being discharged through the second vent 212.

[0048] See also Figure 4-11The wind force enhancement assembly 222 includes a supercharging block 2221, a first air guide block 2222, a second air guide block 2223 and a shuttle block 2224. A supercharging channel 22211 is provided inside the supercharging block 2221. On the wind path of the air duct 23, the front opening width of the supercharging channel 22211 is greater than the rear opening width. Therefore, when air passes through the supercharging channel 22211, the speed will increase. The first air guide block 2222 and the second air guide block 2223 are respectively arranged on both sides of the supercharging channel 22211, and the shuttle block 2224 is arranged at the center of the notch 2211. A first arcuate surface 22221 is provided on the side wall of the first air guide block 2222, a second arcuate surface 22231 is provided on the side wall of the second air guide block 2223, the first end of the shuttle block 2224 is located at a position corresponding to the center of the rear end opening of the supercharging channel 22211, and the second end of the shuttle block 2224 is located at a position corresponding to the center of the gap between the second air guide block 2223 and the second end of the annular air guide plate 221. When the accelerated air leaves the supercharging block 2221, it will first be divided into two parts, left and right, by the shuttle block 2224. The air on the right side contacts the first air guide block 2222 and moves to the rear end of the shuttle block 2224 along the first arcuate surface 22221. The air on the left side contacts the second air guide block 2223 and moves to the rear end of the shuttle block 2224 along the second arcuate surface 22231, thereby converging with the air on the right side and continuing to flow along the spiral air duct 23. The first arc surface 22221 and the second arc surface 22231 can ensure that the air will not be blocked or backflow when passing through the notch 2211, thereby ensuring that the air can maintain the accelerated speed.

[0049] See also Figure 4-14 The first air guide block 2222, the second air guide block 2223 and the shuttle block 2224 are all hollow, and the end faces close to the outer surface of the drum 1 are open. The tops of the two side walls of the shuttle block 2224 are respectively provided with a third duct 2225 and a fourth duct 2226, and the top of the first end of the shuttle block 2224 is provided with a fifth vent 22241. When the air is divided into two parts by the shuttle block 2224, a part of the air will enter the interior of the shuttle block 2224 through the fifth vent 22241, and then enter the interiors of the first air guide block 2222 and the second air guide block 2223 through the third duct 2225 and the fourth duct 2226 respectively. That is to say, the first air guide block 2222, the second air guide block 2223 and the shuttle block 2224 will not reduce the contact area between the flowing air and the inner wall of the air cooling sleeve 21. After the air cooling sleeve 21 absorbs the heat of the rotating drum 1, it can transfer the heat to the flowing air more quickly, thereby improving the efficiency of cooling the calcined materials inside the rotating drum.

[0050] See also Figure 4-14The bottom of the first arc surface 22221 is provided with a sixth vent 22222 and a first air baffle 22223. When air enters the interior of the first air guide block 2222 and absorbs heat, it will be discharged through the sixth vent 22222 to prevent excessive air pressure inside the first air guide block 2222. The first air baffle 22223 can ensure that the flow direction of the air discharged through the sixth vent 22222 is the same as the flow direction of the air passing through the right side of the shuttle block 2224, so that the two air flows are merged.

[0051] See also Figure 4-14 The bottom of the second arc-shaped surface 22231 is provided with a seventh vent 22232 and a second air baffle 22233. When air enters the interior of the second air guide block 2223 and absorbs heat, it is discharged through the seventh vent 22232 to prevent excessive air pressure inside the second air guide block 2223. The second air baffle 22233 can ensure that the flow direction of the air discharged through the seventh vent 22232 is the same as the flow direction of the air passing through the left side of the shuttle block 2224, so that the two air flows are merged.

[0052] See also Figure 4-14 The bottom of the second end of the shuttle block 2224 is provided with an eighth vent 22242, and a wind shield 2227 is provided inside the shuttle block 2224. An inclined air delivery channel 22271 is provided inside the wind shield 2227, and the air delivery channel 22271 runs through the wind shield 2227. When air enters the interior of the shuttle block 2224 through the fifth vent 22241, it will first be blocked by the wind shield 2227, ensuring that the air inside the shuttle block 2224 will definitely enter the third pipe 2225 and the fourth pipe 2226, rather than being directly discharged through the eighth vent 22242. When the air at the top of the wind shield block 2227 enters the air supply channel 22271 and moves to the bottom of the wind shield block 2227 through the air supply channel 22271, this part of the air first absorbs heat from the air cooling sleeve 21 below the wind shield block 2227, and then is discharged through the eighth vent 22242 to merge with the air passing through the left and right sides of the shuttle block 2224.

[0053] Embodiment 3

[0054] Based on Example 1, please refer to Figure 1-9The interior of the annular air guide plate 221 is a cavity, and the end surface close to the outer surface of the drum 1 is open. The second end of the annular air guide plate 221 is provided with a splicing pipe 223, and the interiors of two adjacent annular air guide plates 221 are connected through the splicing pipe 223. In other words, after the air enters the interior of the annular air guide plate 221 at the edge, it can enter the adjacent annular air guide plates 221 one by one through the splicing pipe 223 and directly reach the interior of the annular air guide plate 221 at the edge on the other side. The annular air guide plate 221 will not reduce the contact area between the flowing air and the inner wall of the air cooling sleeve 21. After the air cooling sleeve 21 absorbs the heat of the drum 1, it can transfer the heat to the flowing air more quickly, thereby improving the efficiency of cooling the calcined material inside the drum.

[0055] See also Figure 1-17 The wind-driven assembly 4 also includes a second blower 46, a fifth pipe 47, a second air-gathering ring 48, a sixth pipe 49 and a plurality of second transmission assemblies 410. The side walls of the second air-gathering ring 48 are respectively provided with a ninth vent 482 and a tenth vent 483. The second blower 46 can deliver cold air into the interior of the rightmost annular air guide plate 221 through the fifth pipe 47. When the air enters the adjacent annular air guide plates 221 one by one and reaches the interior of the leftmost annular air guide plate 221, it will enter the sixth pipe 49 through the leftmost splicing pipe 223, and enter the ninth vent 482 through the sixth pipe 49, and then enter the second air-gathering cavity 481 in the second air-gathering ring 48. The plurality of second transmission assemblies 410 are all arranged in the second air-gathering cavity 481, and the structure of the second transmission assembly 410 is the same as that of the first transmission assembly 45. When the air enters the second air collecting chamber 481, it will push the second transmission components 410 to rotate continuously, thereby driving the rotating drum 1 to rotate. The second transmission components 410 cooperate with the first transmission components 45, not only making the rotating drum 1 evenly stressed, but also increasing the rotation speed of the rotating drum 1. During the rotation of the second transmission components 410, the air in the second air collecting chamber 481 can be discharged through the tenth vent 483 to prevent the air pressure in the second air collecting chamber 481 from being too high.

[0056] See also Figure 1-20The first transmission assembly 45 further includes an annular enclosure 452 and a conical block 453. The annular enclosure 452 and the conical block 453 are both fixedly arranged in the middle of the force-bearing plate 451, but are located on different sides. The height of the annular enclosure 452 is the same as the height of the force-bearing plate 451, and the width of the annular enclosure 452 is the same as the width of the conical block 453. Wind shelters 4511 are provided at the bottom of the force-bearing plate 451 and on both sides of the conical block 453. When air enters the first air-gathering cavity 431 in the first air-gathering ring 43 through the third vent 432, it will blow toward the middle of the force-bearing plate 451. At this time, the annular enclosure 452 can gather the wind and increase the thrust of the air on the force-bearing plate 451. When the force-bearing plate 451 rotates under force, the conical block 453 can reduce the air resistance on the rotation path of the force-bearing plate 451, so that the air in the first wind collecting cavity 431 flows to both sides of the conical block 453. These two parts of air can directly pass through the force-bearing plate 451 through the wind shelter 4511, further reducing the resistance of the force-bearing plate 451 during rotation.
