Technical Field
[0001] The utility model relates to the technical field of silicon smelting, in particular to an industrial silicon smelting device. Background Art
[0002] Smelting is a refining technology, which refers to the extraction of metals from ores by roasting, smelting, electrolysis and the use of chemical agents, etc., to reduce the impurities contained in the metal or increase a certain component in the metal to refine the required metal. In the process of traditional silicon smelting, silicon slag is produced, which can be recycled and reused after screening, but the existing equipment cannot screen silicon slag of different sizes, and manual screening is required, which is not only time-consuming and labor-intensive, but also has low work efficiency and affects subsequent processing.
[0003] Upon investigation, the public (announcement) number: CN202122657774.X discloses an industrial silicon smelting device, which discloses "including a screening box, a feeding port is provided on the top of the screening box, a feeding hopper is installed outside the feeding port, a box door is installed on the front of the screening box, a hinge is installed on the left side wall of the box door, the box door is hinged to the screening box through the hinge, a discharge port is provided at the bottom of the screening box, a screening mechanism is provided inside the screening box, a buffer mechanism is also provided inside the screening box, and the buffer mechanism is arranged above the screening mechanism". Through the coordinated use of the screening frame, the first screening plate, the second screening plate, the first discharge channel, the second discharge channel and the guide trough, the multi-stage screening effect is achieved, and the silicon slag can be screened into multiple grades according to different particle sizes. The screening effect is good and the screening efficiency is high.
[0004] However, the multiple groups of screening plates arranged therein are all tilted and fixed in the screening box, and multi-stage screening is achieved by the silicon slag rolling on the screening plates. When the silicon slag has an irregular shape, it cannot roll on the screening plates, and the silicon slag remaining on the screening plates will block the subsequent falling of the silicon slag, seriously affecting the screening efficiency of the silicon slag. In addition, the silicon slag only relies on gravity to roll on the screening plates to achieve screening.

[0025] Reference Figure 1-6 The utility model provides an industrial silicon smelting device: an industrial silicon smelting device, comprising a screening box 1, a protective top plate 2 is fixedly installed on the top of the screening box 1 by screws, and a feed port is opened in the middle of the protective top plate 2, a discharge port 5 is arranged at the bottom end of the screening box 1, and supporting legs are fixedly installed around the bottom of the discharge port 5, and locking universal wheels are movably installed at the bottom of the supporting legs.
[0026] In this embodiment: After investigation, the public (announcement) number: CN202122657774.X discloses an industrial silicon smelting device, which discloses "including a screening box, a feeding port is opened on the top of the screening box, a feeding hopper is installed outside the feeding port, a box door is installed on the front of the screening box, a hinge is installed on the left side wall of the box door, the box door is hinged to the screening box through the hinge, a discharge port is opened at the bottom of the screening box, a screening mechanism is provided inside the screening box, and a buffer mechanism is also provided inside the screening box, and the buffer mechanism is arranged above the screening mechanism". Through the coordinated use of the screening frame, the first screening plate, the second screening plate, the first discharge channel, the second discharge channel and the guide trough, the multi-stage screening effect is achieved, and the silicon slag can be screened into multiple grades according to different particle sizes. The screening effect is good and the screening efficiency is high.
[0027] However, the multiple groups of screening plates arranged therein are all tilted and fixed in the screening box, and multi-stage screening is achieved by the silicon slag rolling on the screening plates. When the silicon slag has an irregular shape, it cannot roll on the screening plates, and the silicon slag remaining on the screening plates will block the subsequent falling of the silicon slag, seriously affecting the screening efficiency of the silicon slag. In addition, the silicon slag only relies on gravity to roll on the screening plates to achieve screening. The rolling speed of the silicon slag on the screening plates is too slow, which will further affect the screening speed of the silicon slag. In order to solve this technical problem, a transmission frame 6, a drive assembly 12, a drive shaft 13, and an eccentric wheel 14 are added to the application document.
[0028] A transmission frame 6 is movably installed at the bottom of the screening box 1, and the transmission frame 6 is fixedly installed with a first screening plate 7, a second screening plate 8, and a third screening plate 9 in sequence from bottom to top. By arranging a plurality of screening plates with different screening specifications inside the screening box 1, screening processing of different levels of silicon slag can be achieved. A driving assembly 12 is fixedly installed on the front of the screening box 1, and a driving shaft 13 is fixedly connected to the output shaft of the driving assembly 12. An eccentric wheel 14 that cooperates with the transmission frame 6 is fixedly sleeved on the outside of the driving shaft 13. The eccentric wheel 14 is driven to rotate by the driving assembly 12, thereby driving the transmission frame 6 and multiple groups of screening plates vibrate reciprocatingly up and down to accelerate the rolling speed of silicon slag on the screening plate, improve the screening speed of silicon slag, and prevent irregular silicon slag from staying on the screening plate. The driving component 12 is composed of a driving motor and a reducer, which is a common existing technology at present. A discharge port 15 is provided on the outer side of the screening box 1 to cooperate with the first screening plate 7, the third screening plate 9, and the third screening plate 9. The silicon slag after screening by the first screening plate 7, the second screening plate 8, and the third screening plate 9 can be discharged from the corresponding discharge port 15 along one end, which is convenient for collecting the screened silicon slag.
[0029] As a further implementation scheme of the above technical scheme: the first screen plate 7, the second screen plate 8, and the third screen plate 9 are all tiltedly arranged on the transmission frame 6, the first screen plate 7 and the third screen plate 9 have the same tilt direction, and the second screen plate 8 is tilted in the opposite direction to the first screen plate 7 and the third screen plate 9, so that the silicon slag screened by the first screen plate 7, the second screen plate 8, and the third screen plate 9 can be discharged along both sides of the screening box 1 for easy classification and collection.
[0030] The surfaces of the first screening plate 7, the second screening plate 8 and the third screening plate 9 are all provided with dense screening holes, and the sizes of the screening holes on the first screening plate 7, the second screening plate 8 and the third screening plate 9 gradually increase. By using multiple groups of screening plates with different screening specifications, multi-stage screening of silicon slag can be achieved, thereby improving the screening effect and efficiency.
[0031] According to the above content, in order to be able to buffer when silicon slag is fed, a buffer plate 3 and a spring telescopic rod 4 are arranged inside the screening box 1;
[0032] Two groups of buffer plates 3 are movably installed on the upper part of the screening box 1, and a plurality of spring telescopic rods 4 are movably connected to the bottom of the two groups of buffer plates 3. After the silicon slag falls on the buffer plates 3, pressure is applied to the buffer plates 3. The buffer plates 3 flip downward and apply pressure to the spring telescopic rods 4, so that the spring telescopic rods 4 shrink inward, and the springs in the spring telescopic rods 4 are used to buffer the impact force, thereby effectively slowing down the falling speed of the silicon slag.
[0033] As a further implementation scheme of the above technical scheme: two groups of buffer plates 3 are located on the left and right sides of the inside of the screening box 1. The two groups of buffer plates 3 cooperate with each other to perform multi-level buffering on the falling silicon slag, thereby improving the buffering effect on the falling silicon slag, and the ends of the two groups of buffer plates 3 away from the inner wall of the screening box 1 are tilted downward, and the inclination angle of the buffer plates 3 is 30-60°. The buffer plates 3 are tilted to facilitate the silicon slag to slide down along the top slope of the buffer plates 3.
[0034] The number of spring telescopic rods 4 under a single buffer plate 3 is 2-4 groups. The end of the spring telescopic rod 4 away from the buffer plate 3 is hingedly connected to the inner wall of the screening box 1, and the two ends of the spring telescopic rod 4 are movably connected to the buffer plate 3 and the screening box 1. When the buffer plate 3 is subjected to force to squeeze the spring telescopic rod 4, the spring telescopic rod 4 can automatically adjust its position to ensure that the buffer plate 3 can be stably flipped downward.
[0035] According to the above content, in order to buffer the silicon slag when it is fed, a guide rail 10 is provided on the inner wall of the screening box 1 and a guide sleeve 11 is provided on the transmission frame 6;
[0036] A plurality of guide sleeves 11 are arranged below the transmission frame 6, and a guide rail 10 cooperating with the guide sleeve 11 is fixedly installed on the inner wall of the screening box 1. The transmission frame 6 is movably installed inside the screening box 1 through the guide rail 10 and the guide sleeve 11. The moving direction of the transmission frame 6 can be restricted by cooperating with the guide rail 10 and the guide sleeve 11, thereby improving the stability of the transmission frame 6 and multiple groups of screening plates during movement, thereby improving the screening effect of the overall screening of silicon slag.
[0037] According to the above content, in order to improve the stability of the transmission frame 6 during reciprocating movement, two sets of eccentric wheels 14 are provided on the driving shaft 13;
[0038] There are two groups of eccentric wheels 14, both of which are located below the transmission frame 6. The outer walls of the eccentric wheels 14 are against the bottom of the transmission frame 6. The driving assembly 12 drives the driving shaft 13 and the two groups of eccentric wheels 14 to rotate, which can provide power for the movement of the transmission frame 6 at two locations to ensure that the transmission frame 6 can move up and down stably.
[0039] Working principle:
[0040] When the utility model is used, the silicon slag produced by smelting is put into the screening box 1 along the feeding port on the protective top plate 2. After entering the screening box 1, the silicon slag falls on the two groups of buffer plates 3 in succession. After the silicon slag falls on the buffer plates 3, pressure is applied to the buffer plates 3. The buffer plates 3 turn downward and apply pressure to the spring telescopic rods 4, so that the spring telescopic rods 4 shrink inwardly. The springs in the spring telescopic rods 4 are used to buffer the impact force, which effectively slows down the falling speed of the silicon slag and reduces the impact force on the screening plate below. After the silicon slag passes through the two groups of buffer plates 3, it is sequentially The silicon slag falls onto the third screening plate 9, the second screening plate 8 and the first screening plate 7, and is screened at multiple levels by multiple groups of screening plates, and the screened silicon slag is discharged along the discharge port 15 and the discharge port 5 on both sides. At the same time, during screening, the driving shaft 13 and the eccentric wheel 14 are driven to rotate by the driving assembly 12, and the transmission frame 6 and multiple groups of screening plates are driven to move up and down reciprocatingly, thereby accelerating the rolling speed of the silicon slag on the screening plate and improving the screening speed of the silicon slag. At the same time, the screening plate vibrates up and down to prevent irregular silicon slag from staying on the screening plate.
