Description

Technical Field

[0001] This utility model relates to the field of industrial silicon refining furnace technology, and more specifically, it relates to a gas mixing device for an industrial silicon refining furnace. Background Technology

[0002] In industrial silicon refining processes, various gases are typically supplied to the refining furnace to meet the process requirements at different stages. These gases include reducing gases, protective gases, and reactant gases. The input volume and flow rate of different gases have a significant impact on the refining effect. However, in existing technologies, gas input devices have significant limitations in terms of adjustment, making it difficult to precisely control the flow rate and velocity of multiple gases. They often rely on manual adjustment or fixed flow rates, resulting in a lack of flexibility and precision in the process. This operating method not only increases the workload of workers but also easily leads to process deviations due to improper adjustment, affecting product quality and refining efficiency.

[0003] Furthermore, in actual operation, due to the variety of gas types and frequent changes in flow rate requirements, traditional gas delivery systems often struggle to respond quickly during switching and adjustments, which can easily lead to uncontrolled gas mixing ratios or input fluctuations, causing process parameters to deviate from preset values. In particular, during the production process of industrial silicon refining furnaces, even slight changes in the flow rate of different gases can significantly affect the reaction intensity, refining temperature, and impurity removal effect. Due to the lack of flexible and efficient control mechanisms, existing equipment is unable to adapt to the changing production demands, thus hindering the optimization and upgrading of the refining process.

[0029] Please see Figures 1-5An industrial silicon refining furnace mixing device includes a mixing tank 1, a connecting pipe 2 connected to the top surface of the mixing tank 1, an input pipe 3 at the top of the connecting pipe 2, and multiple sets of input pipes 3 connected to the top of the connecting pipe 2. Each set of input pipes 3 has a dispensing mechanism installed at its top. The dispensing mechanism includes a connecting sleeve 4, a sliding groove 5, a slider 6, a baffle 7, a connecting plate 8, a connecting ring 9, a mating sleeve 10, an adjusting sleeve 11, a threaded groove 12, and a positioning mechanism. The connecting sleeve 4 is fixed to the top of the input pipe 3. Multiple sets of sliding grooves 5 are distributed inside the connecting sleeve 4. The slider 6 slides within the multiple sets of sliding grooves 5. The baffle 7 is fixed inside the multiple sets of sliders 6. The connecting plate 8 is fixed to the outer wall of the multiple sets of baffles 7. The connecting ring 9 is fixed to the top of the multiple sets of connecting plates 8. The mating sleeve 10 is fixed inside the connecting sleeve 4. The adjusting sleeve 11 is movable inside the connecting sleeve 4 and rotatably connected to the connecting ring 9. The threaded groove 12 is located inside the adjusting sleeve 11 and is threadedly connected to the mating sleeve 10.

[0030] The positioning mechanism includes a positioning groove 13, a positioning block 14, a return spring 15, and a limiting sleeve 16. The positioning groove 13 is provided with several sets distributed on the outer wall of the adjusting sleeve 11. The positioning block 14 is provided with multiple sets that slide on the outer wall of the connecting sleeve 4. The return spring 15 is connected to the top of the multiple sets of positioning blocks 14 and fixedly connected to the outer wall of the connecting sleeve 4 at its bottom end. The limiting sleeve 16 slides on the outer wall of the connecting sleeve 4. The positioning block 14 and the positioning groove 13 cooperate to achieve limiting by the elastic force of the return spring 15, so as to ensure the stable positioning of the adjusting sleeve 11 during use.

[0031] A limiting mechanism is provided on the outside of the limiting sleeve 16. The limiting mechanism includes a support rod 17, an abutment block 18, a rotating sleeve 19, an abutment plate 20, and an unlocking hole 21. Multiple sets of support rods 17 are fixed to the bottom surface of the limiting sleeve 16. The abutment block 18 is fixed to the bottom end of multiple sets of support rods 17. The rotating sleeve 19 rotates on the outer wall of the connecting sleeve 4. The abutment plate 20 is fixed to the top surface of the rotating sleeve 19. Multiple sets of unlocking holes 21 are distributed on the outside of the abutment plate 20. Through the cooperation of the abutment block 18 and the rotating mechanism, the limiting sleeve 16 can be locked and unlocked at a specific position, thereby enhancing the reliability of the overall structure.

[0032] A positioning sleeve 22 is fixedly provided on the bottom surface of the rotating sleeve 19. A compression spring 23 is fixedly provided on the inner side of the positioning sleeve 22. Multiple sets of compression springs 23 are provided. A blocking groove 24 is opened on the outer wall of the connecting sleeve 4. Multiple sets of blocking grooves 24 are distributed on the outer wall of the connecting sleeve 4. A blocking block 25 is fixedly provided at the bottom end of each set of compression springs 23. The multiple sets of blocking blocks 25 abut against the multiple sets of blocking grooves 24 respectively. The elastic force of the compression spring 23 pushes the blocking block 25 into the blocking groove 24, so that the rotating sleeve 19 can be stably positioned in different positions and prevent automatic rotation.

[0033] A limiting plate 26 is fixedly provided on the inner side of the limiting sleeve 16, and a limiting groove 27 is provided on the outer wall of the connecting sleeve 4. Multiple sets of limiting plates 26 and limiting grooves 27 are provided and slidably connected. Through the sliding cooperation between the limiting plates 26 and the limiting grooves 27, the movement range of the limiting sleeve 16 is limited to prevent it from falling out or being misaligned.

[0034] Multiple sets of sliders 6 are fixedly provided with guide blocks 28 on their outer sides, and multiple sets of slide grooves 5 are provided with guide grooves 29 on their outer sides. Multiple sets of guide blocks 28 slide in multiple sets of guide grooves 29 respectively. Through the sliding guidance of the guide blocks 28 in the guide grooves 29, the sliders 6 can move linearly and stably in the slide grooves 5, thereby improving the smoothness of the adjustment process.

[0035] Multiple sets of connecting plates 8 are all set as elastic plates, and a limiting rod 30 is fixedly provided inside the connecting sleeve 4. There are multiple sets of limiting rods 30, and they are all slidably connected to the connecting ring 9. With the help of the elasticity of the connecting plate 8 and the guiding effect of the limiting rod 30, the connection and movement between the connecting ring 9 and the connecting sleeve 4 can be flexibly and controllably achieved.

[0036] Multiple sets of adjusting sleeves 11 are rotatably connected to the top of a connecting shaft 31. A pressure relief valve 32 is installed on the top surface of the mixing tank 1. The adjusting sleeve 11 and the mixing tank 1 are rotatably connected through the connecting shaft 31. The pressure relief valve 32 is used to automatically release gas when the gas pressure is too high, so as to ensure the safe operation of the system.

[0037] In this embodiment, during use, multiple sets of connecting shafts 31 are connected to external gas delivery pipes, and various gases are delivered to the mixing tank 1 for mixing via the input pipe 3. When it is necessary to adjust the input amount of different gases, rotating the adjusting sleeve 11 causes the mating sleeve 10 to engage with the threaded groove 12, which in turn causes the adjusting sleeve 11 to drive the connecting ring 9, thereby moving the multiple sets of connecting plates 8 and the baffles 7. The multiple sets of baffles 7 slide along the sliding groove 5 and the guide groove 29 via the slider 6 and the guide block 28, respectively. Adjusting the gap between multiple sets of baffles 7 adjusts the flow area of ​​the gas, thereby adjusting the flow rate and flow rate of the gas. After adjustment, the limiting sleeve 16 abuts against the outer wall of multiple sets of positioning blocks 14, so that the bottom end of the multiple sets of positioning blocks 14 abuts against the adjusting sleeve 11 in the positioning groove 13 for limiting. The abutting plate 20 abuts against the bottom end of multiple sets of abutting blocks 18 to support and limit the limiting sleeve 16. The multiple sets of compression springs 23 push the blocking block 25 to abut against the blocking groove 24 to rotate and position the rotating sleeve 19.

[0038] More specifically, before adjustment, rotating the rotating sleeve 19 causes the abutment plate 20 to rotate, moving multiple sets of unlocking holes 21 below the abutment block 18. This releases the multiple sets of abutment blocks 18 from contact with the abutment plate 20, releasing the limit sleeve 16 and pushing the limit sleeve 16 to release its contact with multiple sets of positioning blocks 14. Multiple sets of reset springs 15 pull the positioning blocks 14 so that their bottom ends disengage from the positioning grooves 13, releasing the positioning of the adjusting sleeve 11. When rotating the rotating sleeve 19, a certain amount of torque needs to be applied, causing multiple sets of blocking grooves 24 to push the blocking blocks 25 away and compress the compression springs 23. When the multiple sets of blocking blocks 25 move to the next set of blocking grooves 24, the compression springs 23 reset and push the blocking blocks 25 to abut against the blocking grooves 24. When the rotating sleeve 19 is continuously rotated, the multiple sets of blocking blocks 25 continuously move within the multiple sets of blocking grooves 24.

[0039] In summary, during use or operation of the overall equipment: In use, multiple sets of connecting shafts 31 are connected to external gas delivery pipes, and various gases are delivered to the mixing tank 1 for mixing via the input pipe 3. When it is necessary to adjust the input volume of different gases, rotating the adjusting sleeve 11 causes the mating sleeve 10 to engage with the threaded groove 12, which in turn causes the adjusting sleeve 11 to drive the connecting ring 9, thereby moving the multiple sets of connecting plates 8 and the baffles 7. The multiple sets of baffles 7 move along the sliding groove 5 and the guide groove 29 via the slider 6 and the guide block 28. The sliding mechanism adjusts the gap between multiple sets of baffles 7, thereby adjusting the flow area of ​​the gas and thus regulating the flow rate and volume of the gas. After adjustment, the limiting sleeve 16 abuts against the outer wall of multiple sets of positioning blocks 14, causing the bottom of the multiple sets of positioning blocks 14 to abut against the adjusting sleeve 11 in the positioning groove 13 for limiting. The abutting plate 20 abuts against the bottom of multiple sets of abutting blocks 18 to support and limit the limiting sleeve 16. The multiple sets of compression springs 23 push the blocking block 25 to abut against the blocking groove 24 to rotate and position the rotating sleeve 19.

[0040] Before adjustment, rotating the rotating sleeve 19 causes the abutment plate 20 to rotate, moving multiple sets of unlocking holes 21 below the abutment block 18. This releases the multiple sets of abutment blocks 18 from contact with the abutment plate 20, releasing the limit sleeve 16 and pushing the limit sleeve 16 to release its contact with multiple sets of positioning blocks 14. Multiple sets of reset springs 15 pull the positioning blocks 14 so that their bottom ends disengage from the positioning grooves 13, releasing the positioning of the adjusting sleeve 11. When rotating the rotating sleeve 19, a certain amount of torque needs to be applied, causing multiple sets of blocking grooves 24 to push the blocking blocks 25 away and compress the compression springs 23. When the multiple sets of blocking blocks 25 move to the next set of blocking grooves 24, the compression springs 23 reset and push the blocking blocks 25 to abut against the blocking grooves 24. When the rotating sleeve 19 is continuously rotated, the multiple sets of blocking blocks 25 continuously move within the multiple sets of blocking grooves 24.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
