The core goal of silicon powder production is "purification" and "fineness", mainly including crushing, grinding, grading, purification, drying, and packaging steps, and the bucket elevator is needed for conveying between different steps.

[0011] Preferably, the inside of the feeding part is connected with a discharge bar, the discharge bar is a horizontal bar structure, the inside of the discharge bar is provided with a baffle movably inserted into the feeding part, the bottom of the baffle is connected with the bottom of the feeding part through a spring, the side structure of the baffle in contact with the discharge bar is the same as that of the discharge bar and coincides with the discharge bar in the natural state of the spring, and the position where the baffle is inserted into the feeding part is sealingly connected by a soft material, the end of the baffle at the bottom outlet of the feeding part is closed in the natural state of the spring, a discharge port is formed below the side part of the feeding part closed by the baffle, and the spring force required for the connecting spring of the feeding part to contract is smaller than the damping of the material rod connecting shaft, that is, after the material rod contacts the feeding part, the baffle is first moved upward, and then the material rod is deflected.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-2 A bucket elevator for silicon micropowder production includes a housing 1. A transmission mechanism 4 and a track 5 are installed inside the housing 1. The transmission mechanism 4 is connected to an external power source, driving the elevator during operation. Buckets 2 are connected to a conveyor belt outside the transmission mechanism 4. The two ends of the buckets 2 are movably engaged within the track 5, allowing the buckets 2 to move along the track 5 when the transmission mechanism 4 is operating. Feeding sections 3 and discharging plates 6 are located on the left and right sides of the housing 1. Material enters the buckets 2 from the feeding sections 3 and exits from the discharging plates 6, thus realizing the conveying function of the bucket elevator. The working principle of the bucket elevator is existing technology and will not be described in detail here. Please refer to [link to relevant documentation]. Figure 7 The hopper 2 has a semi-circular structure. A damping shaft connects a feed rod 21 to the center of each side of the hopper 2. The top of the feed rod 21 is connected to the top of the hopper 2 via an isolation cover 211. The isolation cover 211 is made of an airtight, soft material and can expand and retract with the movement of the feed rod 21. Simultaneously, as the hopper 2 gradually approaches the feed section 3 from below via the transmission mechanism 4, the feed rod 21 is in a retracted state, meaning its outer end overlaps with the bottom of the feed section 3. This allows the powdered material in the silicon micropowder production process to enter the hopper 2 along the feed rod 21, reducing material loss. Furthermore, when the feed rod 21 contacts the bottom of the feed section 3, it is deflected by the pressure of the feed section 3, causing the isolation cover 211 at the top of the feed rod 21 to expand, achieving a semi-closed top for the hopper 2. This reduces material loss during transport and facilitates material discharge.

[0021] Please see Figure 3The feed section 3 is internally connected to a discharge bar 31. The discharge bar 31 does not affect the feeding of the feed section 3. A baffle 32 is movably inserted into the bottom outlet of the feed section 3 on the inner side of the discharge bar 31. The bottom of the baffle 32 is movably connected to the bottom of the feed section 3 by a spring. The right side structure of the baffle 32 is the same as that of the discharge bar 31. In the natural state, the opening of the contact part between the baffle 32 and the discharge bar 31 overlaps, and external materials can enter the feed section 3 normally. At this time, the left side of the baffle 32 closes the inlet of the discharge bar 31, and the damping of the damping shaft of the material rod 21 is greater than the elastic force required for the deformation of the spring connected to the bottom of the baffle 32. When the material rod 21 contacts the baffle 32, the baffle 32 is pressed upward, so that the discharge port 32 opened on the lower side of the baffle 32... The outlet of the feed section 3 coincides with that of the feed section 3, and the right side of the baffle 32 is misaligned with the discharge rail 31, closing the discharge rail 31. At this time, the material between the baffle 32 and the discharge rail 31 enters the hopper 2 under the action of gravity, realizing quantitative feeding. This avoids the problems of material overflow and high hopper pressure that are easy to occur due to the difficulty in controlling the feeding rate of traditional bucket elevators. After the material between the baffle 32 and the discharge rail 31 is discharged, the baffle 32 will not return to its original position until the feed rod 21 leaves the feed section 3. At this time, the baffle 32 will close the outlet of the feed section 3 again until the next hopper 2 approaches the feed section 3. This can greatly avoid the problem of material feeding during the blank period between adjacent hoppers in traditional bucket elevators, reduce material loss, and improve the production capacity of silicon micro powder production line.

[0022] Please see Figures 4-6 A guide plate 61 is movably connected to the side of the discharge plate 6 near the hopper 2. The guide plate 61 is connected to both sides of the discharge plate 6 via a torsion spring shaft. In its natural state, the guide plate 61 coincides with the bottom outlet of the hopper 2 that is close to the discharge plate 6, thus achieving a guiding effect and greatly reducing material loss. Furthermore, the guide plate 61 is movably connected and can deflect downwards when subjected to pressure from the hopper 2 without affecting the movement of the hopper 2. Please refer to [link / reference]. Figure 7 The outer side of the hopper 2 is connected to a discharge block 22, the outer end of which has an arc-shaped structure. Both ends of the hopper 2 are symmetrically connected to limiting parts 23. (See reference...) Figure 2 The track 5 has a sliding groove 53, and the limiting part 23 is movably inserted into the vibrating block 52. At the same time, the limiting part 23 is movably connected to the spring block 231 by a spring. In its natural state, the spring block 231 maintains the balance of the hopper 2 in the left and right positions inside the shell 1. Meanwhile, the outer side of the transmission mechanism 4 is provided with multiple evenly distributed slots 41. (See reference...) Figure 4A plug block 24 is connected to the rear side of the hopper 2. The plug block 24 is movably inserted into the slot 41, and the width inside the slot 41 is greater than the width outside the plug block 24. Multiple vibrating blocks 52 are connected to the inner side of the track 5 opposite to the discharge block 22. The vibrating blocks 52 are evenly distributed and located above the discharge plate 6. When the discharge block 22 passes the vibrating block 52, the hopper 2 is inverted, and the material inside the hopper 2 falls onto the discharge plate 6 for discharge. At the same time, when the discharge block 22 passes the vibrating block 52, the arc-shaped part of the outer end of the discharge block 22 overlaps with the outer end of the vibrating block 52, and the discharge block 22 will be subjected to the pressure of the vibrating block 52. With the cooperation of the spring block 231, the hopper 2 vibrates left and right, which can promote the discharge of the material inside the hopper 2, greatly reduce the problem of material residue inside the hopper 2, and improve the conveying efficiency of the bucket elevator in silicon micro powder production.

[0023] Please see Figure 2 The bottom of track 5 is connected to a toothed block 51, which is located on one side of the chute 53. When the material inside the hopper 2 is discharged from the discharge plate 6 and continues to move downward along track 5, please refer to... Figure 7 The outer ends of the connecting shafts on both sides of the feed rod 21 are connected to return gears 25. After the feed bucket 2 moves to the position of the tooth block 51, the return gears 25 will mesh with the tooth block 51, causing the return gears 25 to deflect under the action of the tooth block 51, thereby causing the isolation cover 211 to retract and the feed rod 21 to return to its initial position, so that the feed rod 21 can re-cooperate with the feed section 3 to realize the material receiving function and realize the cyclic operation of the feed bucket 2 inside the bucket elevator.

[0024] Please see Figure 2 Through the cooperation of the feed rod 21 and the baffle 32, the effect of fixed-point and quantitative discharge can be achieved, reducing material loss during the silicon micro powder production process. It can also avoid the problem of overflow caused by excessive material inside the hopper 2 or excessive pressure on the hopper 2, thus reducing material loss and wear and tear on mechanical parts. By setting the damping of the connecting shaft of the feed rod 21 to be greater than the elastic force of the connecting spring of the baffle 32, the pressure of the feed rod 21 on the baffle 32 can be ensured to move the baffle 32 upward and realize the discharge of the feed section 3. At the same time, through the cooperation of the feed rod 21, a guiding effect can be achieved, reducing powder leakage. To address the issue of material dispersion, the pressure exerted by the feed section 3 on the feed rod 21 causes the feed rod 21 to deflect under pressure. This allows the isolation cover 211 to cover the top of the hopper 2, reducing the contact between the powder and the outside environment and preventing dispersion during powder transportation. Simultaneously, as the hopper 2 moves and rotates along the track 5, it also guides the material discharge. With the assistance of the guide plate 61, the powder is easily discharged, significantly improving the problem of material accumulation inside the machine, reducing losses during silicon micropowder production, and enhancing the efficiency and quality of the elevator in silicon micropowder production.

[0025] The method of using this invention is as follows: Install the bucket elevator at the corresponding position on the silicon micropowder production line according to the existing production requirements, so that the feeding section 3 and the discharge plate 6 are connected to other parts of the production line. After the power is turned on and the setup is completed, put it into use. The transmission mechanism 4 starts to work, and its external conveyor belt moves according to... Figure 2 The material moves counterclockwise, causing hopper 2 to approach feed section 3 from the bottom. External material directly enters feed section 3 and passes through discharge gate 31, where it is blocked by baffle 32. As hopper 2 approaches feed section 3, rod 21 first contacts baffle 32, exerting upward pressure. Baffle 32 moves upward, closing discharge gate 31. Powder confined within baffle 32 enters hopper 2 through discharge port 321 along rod 21. Rod 21 deflects towards the bottom of hopper 2 as it moves, causing isolation cover 211 to cover hopper 2. After hopper 2 leaves feed section 3, baffle 32 returns to its original position, and discharge gate 31 opens, allowing material to pass through the area of ​​baffle 32. Baffle 32 then seals the bottom outlet of feed section 3 until the next hopper 2 approaches feed section 3. 3. The hopper 2 containing powder moves along the slide 53 under the operation of the transmission mechanism 4. When the hopper 2 moves and flips along the transmission mechanism 4 to the top of the discharge plate 6, the discharge block 22 contacts the vibrating block 52, which puts pressure on the hopper 2. Under the action of the spring block 231, the hopper 2 vibrates left and right, which accelerates the powder inside the hopper 2 into the discharge plate 6 and discharges it from the discharge plate 6 along the guide plate 61. After the powder is discharged from the hopper 2, it moves closer to the guide plate 61. The guide plate 61 is pressed down and deflects, causing the hopper 2 to move to the bottom of the discharge plate 6. At this time, the guide plate 61 returns to its original position. When the hopper 2 continues to move to the position of the toothed block 51, the toothed block 51 and the return gear 25 mesh. The return gear 25 rotates along the toothed block 51 and causes the material rod 21 to return to its original position and continue to pass through the feeding part 3 to realize the material conveying function.
