Description

Technical Field

[0001] The present invention relates to the technical field of light source production, and in particular to a special light source gas distribution and processing method. Background Art

[0002] The current halogen lamp light source filling gas is mainly composed of inert gas and halogen gas. Among them, the inert gas is mainly argon, neon, helium and krypton, while the halogen gas is mainly iodine vapor or bromine vapor. There are two main processes for light source gas distribution: one is to mix the halogen gas and the inert gas according to the target gas ratio, and the other is to flush the mixed gas into the quartz bulb.

[0003] In the existing technology, manufacturers pre-inject the light source gas into a gas cylinder and mix it inside the cylinder to ensure that the various components of the light source gas are evenly distributed. During gas distribution, the light source gas is drawn from the gas cylinder through a pipe and injected into the quartz bulb. However, in actual production, common gas cylinders on the market have the following problems when mixing the light source gas: because the density of the halogen gas in the light source gas, mainly iodine vapor or bromine vapor, is much greater than that of the inert gas, the halogen gas is easily affected by the density when the gas cylinder is stirred and mixed, and it sinks and centrifuges easily. This causes the halogen gas and the inert gas to stratify, affecting the uniformity of the light source gas mixing. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that when the gas tank is stirred and mixed, the halogen gas is easily affected by the density and sinks and centrifuges, causing the halogen gas and the inert gas to be stratified, affecting the uniformity of the light source gas mixing.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1 , a special light source gas distribution and processing method, the steps are as follows:

[0035] S1: Use dry hot nitrogen to dry and clean the gas distribution equipment in advance;

[0036] S2: Then use the special light source gas distribution device to mix the halogen gas and the inert gas according to the proportion and fill them into the mixing bottle, such as Figure 2-Figure 4 As shown, the special light source gas distribution device includes a tank body 1 and an arc-shaped partition 103. The tank body 1 is used to contain the light source gas, and the tank body 1 has a heating function to maintain the temperature of the light source gas. The top of the tank body 1 is fixedly connected to an upper cover 3, and the top of the upper cover 3 is provided with an air inlet pipe 301 and an air outlet pipe 302. The bottom of the tank body 1 is fixedly connected to an end cover 2, and the end cover 2 is fixedly set. A rotating table 4 is rotatably installed in the middle of the end cover 2. The bottom of the rotating table 4 is fixedly connected to a main shaft 401, and the top thereof is fixedly connected to a pulse wheel 5.

[0037] The end cover 2 is fixedly arranged to provide support force for the entire device. During operation, the main shaft 401 drives the rotating table 4 to rotate, and the rotation of the rotating table 4 drives the impeller 5 to rotate to stir and mix the light source gas in the tank body 1.

[0038] like Figure 13-16As shown, a circular planetary carrier 101 is rotatably installed at the bottom of the tank body 1, and a plurality of planetary gears 17 are fixed to the planetary carrier 101. A first ring gear 15 is fixed to the outer wall of the rotating table 4, and the first ring gear 15 matches the planetary gear 17. A second ring gear 16 is fixed to the inner wall of the end cover 2, and the second ring gear 16 matches the planetary gear 17. A circular rotating ring 102 is rotatably installed at the top of the tank body 1, and an air hole 104 is opened on the partition 103. Two valves 105 are fixed in the air hole 104. One end of the partition 103 is fixed to the planetary carrier 101 and the other end is fixed to the rotating ring 102. A scraper 7 is slidably fitted between the partition 103 and the inner wall of the tank body 1. One side of the scraper 7 rests on the partition 103 and the other side rests on the inner wall of the tank body 1. The top of the scraper 7 rests on the rotating ring 102 and its bottom end rests on the planetary carrier 101.

[0039] During the rotation of the turntable 4, the first ring gear 15 is also driven to rotate, and the first ring gear 15 drives the planetary gear 17 to rotate. Since the planetary gear 17 is engaged with the second ring gear 16 and the second ring gear 16 is fixed on the end cover 2, the planetary gear 17 will also revolve around the turntable 4 during the rotation process.

[0040] During the revolution of the planetary gear 17, the planetary carrier 101 will be driven to rotate. Since the planetary carrier 101 is fixedly connected to the rotating ring 102 through the partition 103, the rotating ring 102, the planetary carrier 101 and the partition 103 will rotate synchronously. During the rotation of the partition 103, the scraper 7 will be driven to rotate in the tank body 1. Since the scraper 7 is against the inner wall of the tank body 1, the halogen gas attached to the inner wall of the tank body 1 will be cleaned during the rotation of the scraper 7.

[0041] like Figure 5-Figure 17 As shown, a pipe fitting 6 is fixed to the end face of the impeller 5, and a slot 601 is provided through the pipe fitting 6. A spherical shell 13 is rotatably installed at the bottom of the pipe fitting 6. A one-way valve 602 is provided on the wall of the pipe fitting 6. A connecting pipe 14 is fixed to the outer wall of the shell 13, and the connecting pipe 14 is connected to the partition 103. A plurality of guide grooves 9 are provided at equal intervals on the rotating ring 102, and two guide blocks 10 are slidingly fitted in the guide groove 9. The bottom end of the guide block 10 is fixed with a connecting rod 8, and the top end of the guide block 10 is hinged with a movable rod 11, which is fixed to the outer wall of the scraper 7. The movable rod 11 is rotatably connected to the end face of the roller 12. The two guide blocks 10 are connected by a spring 18, and the spring 18 is always in a stretched state to apply tension to the guide block 10. A plurality of wedge-shaped protrusions 303 are fixed at equal intervals on the inner end face of the upper cover 3, and the roller 12 rests on the protrusions 303.

[0042] During the rotation of the rotating ring 102, the roller 12 is driven to perform a circular motion in the upper cover 3. Since a plurality of protrusions 303 are distributed circumferentially on the inner wall of the upper cover 3, the roller 12 performs a linear reciprocating motion in the vertical direction under the action of the squeezing of the protrusions 303 and the elastic force of the spring 18 during the circular motion. The roller 12 performs a linear reciprocating motion in the vertical direction and periodically drives the guide block 10 to slide back and forth in the guide groove 9 through the movable rod 11. The guide block 10 drives the scraper 7 to move synchronously through the connecting rod 8.

[0043] like Figures 9-12 The inner wall of the tank body 1, the two scrapers 7 and the partition 103 form a closed space. During the movement of the two scrapers 7, the air pressure in the closed space fluctuates periodically, wherein:

[0044] When the air pressure in the enclosed space decreases, under the action of negative pressure, the enclosed space sucks the gas near the axis of the tank body 1 through the connecting pipe 14 and the pipe 6;

[0045] When the air pressure in the enclosed space increases, the gas drawn into the enclosed space forms a high-pressure airflow under the action of high pressure and is discharged from the air hole 104, and the direction of the high-pressure airflow points to the axis of the tank body 1.

[0046] When the impeller 5 stirs the light source gas, it will cause the light source gas to rotate in the tank body 1. The halogen gas with higher density will perform centrifugal motion under the action of centrifugal force, while the inert gas with lower density is near the axis. By utilizing the changes in air pressure in the above-mentioned confined space, part of the inert gas near the axis is sucked out, and the inert gas in the confined space is made to perform centripetal motion outside the rotation range of the light source gas. The high-speed airflow formed by the inert gas is used to impact the halogen gas in the outer layer of rotation, and the halogen gas is entrained and moved to the vicinity of the axis to alleviate the problem of reduced uniformity caused by the centrifugal phenomenon.

[0047] like Figure 6-Figure 8 As shown, the presence of the one-way valve 602 only allows the gas in the pipe 6 to move into the connecting pipe 14. A slot 601 for gas to pass through is provided on the pipe 6. The bottom end of the slot 601 is located near the bottom of the tank body 1. When the enclosed space is in a low-pressure state, the gas at the bottom of the tank body 1 will be sucked into the enclosed space.

[0048] like Figure 6 and Figure 8 As shown, the air hole 104 is located near the top of the tank body 1. Under the action of the two valves 105, the air hole 104 only allows the gas in the enclosed space to be discharged into the tank body 1. Therefore, when the enclosed space is under high pressure, the gas sucked from the bottom of the tank body 1 in the enclosed space will be transported from the air hole 104 to the top of the tank body 1 to prevent the light source gas from stratifying and reducing the uniformity of mixing.

[0049] The steps for gas mixing are as follows:

[0050] S21: injecting halogen gas and inert gas into the tank body 1 through the air inlet pipe 301 and driving the main shaft 401 to rotate;

[0051] S22 : The main shaft 401 drives the rotating table 4 to rotate. The rotation of the rotating table 4 drives the impeller 5 to rotate, so as to stir and mix the light source gas in the tank body 1 .

[0052] S23: During the rotation of the turntable 4, the first ring gear 15 is also driven to rotate, and the first ring gear 15 drives the planetary gear 17 to rotate. Since the planetary gear 17 is engaged with the second ring gear 16 and the second ring gear 16 is fixed on the end cover 2, the planetary gear 17 will also revolve around the turntable 4 during the rotation process.

[0053] During the revolution of the planetary gear 17, the planetary carrier 101 will be driven to rotate. Since the planetary carrier 101 is fixedly connected to the rotating ring 102 by the partition 103, the rotating ring 102, the planetary carrier 101 and the partition 103 will rotate synchronously. During the rotation of the partition 103, the scraper 7 will be driven to rotate in the tank body 1. Since the scraper 7 is against the inner wall of the tank body 1, the halogen gas attached to the inner wall of the tank body 1 due to centrifugal action will be cleaned during the rotation of the scraper 7.

[0054] S24: During the rotation of the rotating ring 102, the roller 12 is driven to perform circular motion in the upper cover 3. Since a plurality of protrusions 303 are distributed circumferentially on the inner wall of the upper cover 3, the roller 12 performs linear reciprocating motion in the vertical direction under the action of the squeezing of the protrusions 303 and the elastic force of the spring 18 during the circular motion. The roller 12 performs linear reciprocating motion in the vertical direction and periodically drives the guide block 10 to slide back and forth in the guide groove 9 through the movable rod 11. The guide block 10 drives the scraper 7 to move synchronously through the connecting rod 8.

[0055] The inner wall of the tank 1, the two scrapers 7 and the partition 103 form a closed space. During the movement of the two scrapers 7, the air pressure in the closed space fluctuates periodically, wherein:

[0056] When the air pressure in the enclosed space decreases, under the action of negative pressure, the enclosed space sucks the gas near the axis of the tank body 1 through the connecting pipe 14 and the pipe 6;

[0057] When the air pressure in the enclosed space increases, the gas drawn into the enclosed space forms a high-pressure airflow under the action of high pressure and is discharged from the air hole 104, and the direction of the high-pressure airflow points to the axis of the tank body 1.

[0058] When the impeller 5 stirs the light source gas, it will cause the light source gas to rotate in the tank body 1. The halogen gas with higher density will perform centrifugal motion under the action of centrifugal force, while the inert gas with lower density is near the axis. By utilizing the changes in air pressure in the above-mentioned confined space, part of the inert gas near the axis is sucked out, and the inert gas in the confined space is made to perform centripetal motion outside the rotation range of the light source gas. The high-speed airflow formed by the inert gas is used to impact the halogen gas in the outer layer of rotation, and the halogen gas is entrained and moved to the vicinity of the axis to alleviate the problem of reduced uniformity caused by the centrifugal phenomenon.

[0059] S3: The mixed gas bottle is then installed on the exhaust equipment and connected to the pipeline;

[0060] S4: Exhaust the quartz bulb. Before filling the mixed gas, flush the quartz bulb with dry hot nitrogen, and then fill it with the required mixed gas to complete the gas distribution and processing.

[0061] Compared with the existing technology, the gas distribution device provided by the present invention can significantly improve the uniformity of the mixing of halogen gas and inert gas in the lamp source gas during the lamp source gas mixing stage; during the exhaust stage, it can effectively control the mixing of impurity gases in the quartz bulb, thereby improving the various performance and uniformity of the product and extending the product life.
