Each first limiting block 243 and the second limiting block 244 are symmetrical to each other, and the first limiting block 243 and the second limiting block 244 are used to limit the placement of the test tube body 251. The inner cavity of the vacuum chamber 12 is also provided with an oxygen-acetylene spray gun body 346 and a driving assembly. The oxygen-acetylene spray gun body 346 is used to calcine the sidewalls of the test tube body 251 after it is limited, and the driving assembly is used to drive the circular turntable 2 to rotate.

The drive component drives the turntable to rotate intermittently, which, combined with the automatic lifting and positioning of the oxy-acetylene spray gun body 346, enables continuous heating of multiple samples, improving detection efficiency and consistency. The observation window 126 on the sliding door 125 facilitates real-time observation of the melt state.

[0021] like Figures 1 to 6 As shown, in a specific embodiment, a plurality of connectors 121 are provided on one side wall of the vacuum chamber 12, and a bracket 11 is provided through the inner cavity of each connector 121. A mounting base 1 is provided at the bottom end of the bracket 11, and a first interface 122 and a second interface 123 are also provided on the top of the vacuum chamber 12. In this configuration, the specific installation position of the vacuum chamber 12 is determined.

[0022] like Figures 4 to 9 As shown, furthermore, guide grooves 34 are provided on both opposite side walls of the inner cavity of the vacuum chamber 12. The two guide grooves 34 are symmetrical to each other. Sliding rods 341 are slidably arranged inside the inner cavities of the two guide grooves 34. Multiple mounting rods 342 are provided at equal intervals at the bottom of the sliding rods 341, and mounting plates 343 are provided at the bottom of the mounting rods 342. A placement plate 344 is provided on one side wall of the mounting plate 343. Multiple placement rods 345 are provided at the bottom of the placement plate 344, and the end of the placement rod 345 away from the placement plate 344 is attached to the oxygen-acetylene spray gun body 346. In this configuration, the specific installation position of the oxygen-acetylene spray gun body 346 is determined.

[0023] like Figures 4 to 9 As shown, further, movable slides 24 are respectively provided on both sides of the circular placement slot 25 above the circular turntable 2. Each movable slide 24 is symmetrical to the others. A movable slider 241 is slidably disposed in the inner cavity of each movable slide 24. Each movable slider 241 is symmetrical to the others. A first limiting block 243 and a second limiting block 244 are respectively provided above each pair of movable sliders 241. A first return spring 242 is provided in the movable slide 24 of each movable slider 241. The end of each first return spring 242 away from the movable slider 241 is disposed on the inner wall of the movable slide 24. In this configuration, the specific installation positions of the first limiting block 243 and the second limiting block 244 are determined.

[0024] like Figures 4 to 9 As shown, the drive assembly further includes a servo motor 23, which is located at the bottom center of the vacuum chamber 12. A rotating rod 231 is located at the output end of the servo motor 23, with one end of the rotating rod 231 away from the servo motor 23 positioned at the bottom of the circular turntable 2. Positioning blocks 21 are also provided on opposite sides of the vacuum chamber 12, with one end of each positioning block 21 rotatably mounted to the circular turntable 2. This configuration defines the installation position of the drive assembly.

[0025] Example 2:

[0026] The difference between the above embodiments and this embodiment is that: Figures 4 to 9As shown, a device for rapidly identifying the quality of quartz ore includes a circular turntable 2 with an irregularly shaped mounting plate 22 at its bottom. The bottom of the irregularly shaped mounting plate 22 consists of multiple arc-shaped convex surfaces 221 and arc-shaped concave surfaces 222, with each arc-shaped convex surface 221 and arc-shaped concave surface 222 arranged circumferentially. In this configuration, the components of the bottom of the irregularly shaped mounting plate 22 are defined.

[0027] like Figures 4 to 9 As shown in the specific embodiment, two circular mounting cylinders 3 are also provided at the bottom of the inner cavity of the vacuum box 12. The two circular mounting cylinders 3 are symmetrical to each other, and each of the two circular mounting cylinders 3 has a rectangular slot 31, which is symmetrical to each other. Circular insertion rods 32 are movably inserted into the top of each of the two circular mounting cylinders 3. The two circular insertion rods 32 are symmetrical to each other, and a circular ball bearing 321 is provided at the upper end of each of the two circular insertion rods 32. Circular movable plates 322 are provided at one end of each of the two circular insertion rods 32 in the inner cavity of the circular mounting cylinder 3. The two circular movable plates 322 are slidably disposed with respect to the inner cavity of the circular mounting cylinder 3. A second return spring 323 is provided at the bottom of each of the two circular movable plates 322, and the end of the second return spring 323 away from the circular movable plate 322 is located at the bottom of the inner cavity of the circular mounting cylinder 3. Two circular movable plates 322 are provided with connecting rods 33 on opposite sides. The two connecting rods 33 are symmetrical and each moves through a rectangular slot 31. Connecting plates 331 are provided at opposite ends of the two connecting rods 33. The two connecting plates 331 are symmetrical. Connecting rods 332 are provided above the two connecting plates 331. The two connecting rods 332 are symmetrical. Each of the two connecting rods 332 moves through a positioning block 21, and each end away from the connecting plate 331 is provided on a sliding rod 341. In this configuration, when the arc-shaped concave surface 222 of the irregular mounting plate 22 rotates to the circular ball bearing 321, the second return spring 323 is no longer compressed and releases its elastic force, pushing the circular moving plate 322 to slide vertically upward along the inner cavity of the circular mounting cylinder 3. The circular moving plate 322 drives the circular insertion rod 32 and the circular ball bearing 321 to return upward, so that the circular ball bearing 321 fits tightly against the arc-shaped concave surface 222. At the same time, the circular moving plate 322 drives the sliding rod 341 to slide upward along the guide groove 34 through the connecting rod 33, connecting plate 331, and connecting rod 332, thereby driving the oxygen-acetylene spray gun body 346 to move upward, thus ensuring that the oxygen-acetylene spray gun body 346 leaves the test tube body 251.

[0028] Example 3:

[0029] This invention also discloses a method for rapidly identifying the quality of quartz ore, the steps of which are as follows: Step 1: Sample preparation and test tube fixation; about 7g of quartz sand sample is loaded into the test tube body 251 made of high temperature resistant quartz glass, and then the test tube body 251 is placed in the circular placement slot 25 above the circular turntable 2 inside the vacuum chamber 12; at this time, the first reset spring 242 in the movable slide 24 pushes the movable slider 241 to slide, causing the first limiting block 243 and the second limiting block 244 to move closer to each other and fit against the side wall of the test tube body 251, thus completing the stable positioning of the test tube; Step 2: Vacuuming operation of the vacuum chamber; start the vacuum pump connected to the third interface 124 on one side wall of the vacuum chamber 12, and evacuate the inner cavity of the vacuum chamber 12 through the third interface 124. At the same time, use the first interface 122 and the second interface 123 on the top of the vacuum chamber 12 to help adjust the air pressure in the inner cavity until the vacuum degree of the inner cavity of the vacuum chamber 12 is evacuated to -0.1MPa, so as to eliminate the oxidation effect of the quartz sand sample and external contamination during subsequent heating. Step 3: Turntable rotation and spray gun heating; Start the servo motor 23 at the bottom of the vacuum chamber 12, and its output end drives the circular turntable 2 to rotate through the rotating rod 231. The irregularly shaped mounting plate 22 at the bottom of the circular turntable 2 rotates synchronously; When the arc-shaped convex surface 221 presses the circular ball 321 of the circular insertion rod 32 on the circular mounting cylinder 3, the circular moving plate 322 compresses the second return spring 323, and drives the sliding rod 341 to move down along the guide groove 34 through the connecting rod 33, connecting plate 331, and connecting rod 332, so that the oxygen-acetylene spray gun body 346 is aligned with the test tube body 251; After the circular turntable 2 rotates 90°, the servo motor 23 stops, and the oxygen-acetylene spray gun body 346 is heated to 1600-1800℃ and maintained at this temperature for about 3 minutes; Step 4: Stop heating and allow natural cooling; close the oxygen-acetylene torch body 346 and allow the test tube body 251 and the internal quartz sand melt to cool naturally in the vacuum chamber 12. During the cooling process, observe the state of the melt through the observation window 126 on the front sliding door 125 of the vacuum chamber 12. Step 5: Sample Removal and Quality Assessment; After cooling, open the sliding door 125 of the vacuum chamber 12, remove the test tube body 251, analyze the transparency and surface morphology of the melt inside the test tube body 251, and combine it with the preset quartz sand quality assessment database to finally determine the quality grade of the quartz sand sample.

[0030] The implementation principle of the device for rapidly identifying the quality of quartz ore in this embodiment is as follows: First, sample preparation and fixation are carried out before testing. Approximately 7g of quartz sand sample is placed into a test tube body 251 made of high-temperature resistant quartz glass. Then, the test tube body 251 containing the sample is placed in the circular placement slot 25 above the circular turntable 2 inside the vacuum chamber 12. At this time, the movable slider 241 in the movable sliding grooves 24 on both sides of the circular placement slot 25 slides under the elastic force of the first return spring 242, which drives the first limiting block 243 and the second limiting block 244 respectively set above the movable slider 241 to move closer to each other until they are tightly attached to the side wall of the test tube body 251, thus achieving stable positioning of the test tube body 251. Next, the vacuuming process begins. The vacuum pump connected to the third interface 124 on one side wall of the vacuum chamber 12 is started. The vacuum pump pumps the air inside the vacuum chamber 12 through the third interface 124. During the process, the first interface 122 and the second interface 123 set on the top of the vacuum chamber 12 can be used to help adjust the air pressure inside the chamber until the vacuum degree inside the vacuum chamber 12 is reduced to -0.1MPa. This eliminates the oxidation effect and external contamination that the quartz sand sample may be affected by during subsequent heating, and provides a clean vacuum environment for testing. The heating process is then initiated. First, the servo motor 23, located in the middle of the bottom of the vacuum chamber 12, is turned on. The output of the servo motor 23 drives the rotating rod 231 to rotate, which in turn drives the circular turntable 2 connected to the top to rotate. When the circular turntable 2 rotates, the irregularly shaped mounting plate 22 at its bottom rotates synchronously. The bottom of the irregularly shaped mounting plate 22 consists of multiple circumferentially distributed arc-shaped convex surfaces 221 and arc-shaped concave surfaces 222. When the arc-shaped convex surfaces 221 of the irregularly shaped mounting plate 22 rotate to above the two mutually symmetrical circular mounting cylinders 3 at the bottom of the vacuum chamber 12, the arc-shaped convex surfaces 221 will squeeze the circular ball bearing 321 at the top of the circular insertion rod 32 above the circular mounting cylinder 3, causing the circular insertion rod 32 to move vertically downward along the inner cavity of the circular mounting cylinder 3. The circular moving plate 322 connected to one end of the circular insertion rod 32 in the inner cavity of the circular mounting cylinder 3 slides downward synchronously, compressing the second return spring 323 connected to the bottom of the circular moving plate 322 and the bottom of the inner cavity of the circular mounting cylinder 3. The connecting rod 33, located on the opposite side of the movable plate 322, moves downward along the rectangular slot 31 on the circular mounting cylinder 3. The connecting plate 331 connected to the opposite end of the connecting rod 33 and the connecting rod 332 connected above the connecting plate 331 move downward synchronously. The end of the connecting rod 332 away from the connecting plate 331 passes through the positioning blocks 21 on both sides of the vacuum chamber 12 and connects to the sliding rod 341. Therefore, the connecting rod 332 will drive the sliding rod 341 to slide downward in the guide grooves 34 opened on the opposite side walls of the inner cavity of the vacuum chamber 12. The multiple equally spaced mounting rods 342 at the bottom of the sliding rod 341, the mounting plate 343 at the bottom of the mounting rod 342, and the placement rod 345 at the bottom of the placement plate 344 on one side wall of the mounting plate 343 move downward synchronously. Finally, the oxygen-acetylene spray gun body 346 connected to the end of the placement rod 345 away from the placement plate 344 moves downward until the oxygen-acetylene spray gun body 346 moves to the position corresponding to the quartz sand sample in the test tube body 251. When the arc-shaped concave surface 222 of the irregular mounting plate 22 rotates to the circular ball bearing 321, the second return spring 323 is no longer compressed and releases its elastic force, pushing the circular moving plate 322 to slide vertically upward along the inner cavity of the circular mounting cylinder 3. The circular moving plate 322 drives the circular insertion rod 32 and the circular ball bearing 321 to return upward, so that the circular ball bearing 321 tightly fits the arc-shaped concave surface 222. At the same time, the circular moving plate 322 drives the sliding rod 341 to slide upward along the guide groove 34 through the connecting rod 33, connecting plate 331, and connecting rod 332, thereby driving the oxygen-acetylene spray gun body 346 to move upward, thus ensuring The oxy-acetylene spray gun body 346 leaves the test tube body 251; during the rotation of the circular turntable 2, the positioning blocks 21 on both sides of the vacuum chamber 12 play an auxiliary positioning role for the circular turntable 2. When the circular turntable 2 rotates 90 degrees, the servo motor 23 stops running, realizing the switching of the test tube body 251. At this time, the oxy-acetylene spray gun body 346 is exactly located on the outer wall of the switched test tube body 251. Then the oxy-acetylene spray gun body 346 is started, its heating temperature is adjusted to 1600-1800℃, and this temperature is maintained for about 3 minutes to heat the quartz sand sample in the test tube body 251. Finally, the cooling analysis is performed. After the heating maintenance time is over, the oxy-acetylene torch body 346 is turned off, and the test tube body 251 and the quartz sand melt inside are allowed to cool naturally in the vacuum chamber 12. During the cooling process, the state of the melt can be observed through the observation window 126 set on the sliding door 125. After cooling is completed, the sliding door 125 is opened, the test tube body 251 is taken out, and the transparency and surface morphology of the melt inside the test tube body 251 are analyzed. Combined with the preset quartz sand quality judgment database, the quality grade of the quartz sand sample is finally determined.

5. A method for rapidly identifying the quality of quartz ore, characterized in that, The apparatus for rapidly identifying the quality of quartz ore using any one of claims 1 to 4 comprises the following steps: Step 1: Sample preparation and test tube fixation; about 7g of quartz sand sample is loaded into the test tube body (251) made of high temperature resistant quartz glass, and then the test tube body (251) is placed in the circular placement slot (25) above the circular turntable (2) inside the vacuum chamber (12); at this time, the first reset spring (242) in the sliding groove (24) pushes the sliding slider (241) to slide, causing the first limiting block (243) and the second limiting block (244) to approach each other and fit against the side wall of the test tube body (251), thus completing the stable positioning of the test tube; Step 2: Vacuuming operation of vacuum chamber; start the pump connected to the third interface (124) pipe on one side wall of vacuum chamber (12), and pump air into the inner cavity of vacuum chamber (12) through the third interface (124). At the same time, use the first interface (122) and the second interface (123) on the top of vacuum chamber (12) to help adjust the air pressure in the inner cavity until the vacuum degree of the inner cavity of vacuum chamber (12) is pumped down to -0.1MPa to eliminate the oxidation effect of quartz sand sample and external contamination during subsequent heating; Step 3: Rotating the turntable and heating the spray gun; Start the servo motor (23) at the bottom of the vacuum chamber (12), and its output end drives the circular turntable (2) to rotate through the rotating rod (231). The irregular mounting plate (22) at the bottom of the circular turntable (2) rotates synchronously; When the arc-shaped convex surface (221) squeezes the circular ball (321) of the circular insertion rod (32) on the circular mounting cylinder (3), the circular moving plate (322) compresses the second reset spring (323), and drives the sliding rod (341) to move down along the guide groove (34) through the connecting rod (33), connecting plate (331), and connecting rod (332), so that the oxygen-acetylene spray gun body (346) is aligned with the test tube body (251); After the circular turntable (2) rotates 90°, the servo motor (23) stops, and the oxygen-acetylene spray gun body (346) is heated to 1600-1800℃ and maintained at this temperature for about 3 minutes; Step 4: Stop heating and allow natural cooling; close the oxygen-acetylene torch body (346) and allow the test tube body (251) and the internal quartz sand melt to cool naturally in the vacuum chamber (12). During the cooling process, observe the state of the melt through the observation window (126) on the front sliding door (125) of the vacuum chamber (12). Step 5: Sample removal and quality assessment; After cooling, open the sliding door (125) of the vacuum chamber (12), remove the test tube body (251), analyze the transparency and surface morphology of the melt inside the test tube body (251), and finally determine the quality grade of the quartz sand sample by combining the preset quartz sand quality assessment database.
