Description

Technical Field

[0001] This utility model belongs to the field of industrial silicon production and relates to silicon furnace feeding technology, specifically an industrial silicon furnace feeding device. Background Technology

[0002] Industrial silicon furnaces require the continuous addition of silica, carbonaceous reducing agents, and other necessary porosilicates to ensure the continuity of the smelting process, improve smelting efficiency, enhance product quality, reduce energy consumption and costs, and ensure production safety.

[0003] The reference patent title is: An industrial silicon furnace feeding device (patent publication number: CN220018113U). Through the rotating turntable and partition inside the industrial silicon furnace, the feed hole and feed pipe are aligned, and the silicon raw material falls into the material receiving cavity. The silicon raw material also rotates in the material receiving cavity, so that the silicon raw material falls evenly into the interior of the industrial silicon furnace through the discharge chute, thereby realizing the uniform addition of silicon raw material into the industrial silicon furnace.

[0004] However, the following problems exist when implementing the above technical solutions: The above devices have limitations on the size of the added raw materials. The feeding of the above devices is mainly achieved by downward leakage through a discharge trough of constant size. The size of the discharge trough further limits the size of the added silicon raw materials. If the silicon raw material is too large, it may get stuck at the edge of the discharge trough or be unable to pass through. Silicon raw materials stuck at the edge inevitably affect the rotation of the partition, thus affecting subsequent feeding. Furthermore, if silicon raw materials remain above the discharge trough for a long time and accumulate excessively, it will also affect subsequent feeding and the overall raw material ratio. Therefore, the size of the added silicon raw materials needs to be controlled when using the above devices, which imposes many limitations.

[0005] Therefore, this utility model proposes an industrial silicon furnace feeding device. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an industrial silicon furnace feeding device that addresses the problem that existing industrial silicon furnace feeding devices, which achieve uniform feeding via a rotating plate, struggle to directly process larger silicon raw materials, thus limiting the overall usability of the device.

[0007] To achieve the above objectives, an industrial silicon furnace feeding device is provided according to an embodiment of the first aspect of this utility model, comprising: an industrial silicon furnace, wherein a furnace cover is fixedly disposed on the top of the industrial silicon furnace, and a crushing mechanism is disposed inside the furnace cover, the crushing mechanism comprising:

[0008] A partition component is rotatably connected to the inside of the furnace cover. The partition component includes a turntable and a partition frame, which are fixedly connected but do not contact each other.

[0009] The furnace cover includes a crushing roller and an adjusting roller, both of which are rotatably connected to the inside of the furnace cover and are positioned between the turntable and the partition. A drive cone wheel is fixedly connected to the side of each crushing roller and adjusting roller closest to the furnace cover. Two reversing cone wheels are rotatably connected inside the furnace cover, meshing with the drive cone wheels. A drive rod is rotatably connected inside the furnace cover and fixedly mounted to the reversing cone wheels. The two reversing cone wheels and the drive cone wheels are symmetrically arranged along the same axis.

[0010] The feeding plate is fixedly connected to the inside of the furnace cover. The side of the feeding plate away from the industrial silicon furnace is attached to the partition. Several feeding grooves are opened on the surface of the feeding plate.

[0011] Optionally, the reversing cone wheel near the crushing roller is fixedly connected to the drive rod, and the reversing cone wheel near the adjusting roller is slidably connected to the drive rod.

[0012] Optionally, a sliding groove is provided inside each of the reversing cone pulleys, and a sliding rod is fixedly connected to the drive rod near the surface of the reversing cone pulley on that side, the sliding rod being adapted to the sliding groove.

[0013] Optionally, an adjusting block is slidably connected inside the furnace cover. The adjusting block is rotatably connected to the surface of the driving cone wheel on the adjusting roller. One end of the adjusting block is slidably connected to the surface of the reversing cone wheel on one side of the adjusting roller. A limiting gear is slidably connected inside the adjusting block. A limiting groove is opened on the surface of the furnace cover. Several guide teeth and several positioning teeth are fixedly connected inside the limiting groove. The guide teeth and positioning teeth mesh with the limiting gear.

[0014] Optionally, the guide teeth and the positioning teeth are symmetrically arranged relative to the limiting gear. The number of guide teeth and positioning teeth is the same, but their widths are different. The width of the guide teeth is greater than the width of the positioning teeth, and the ends of both that are away from the limiting gear are flush.

[0015] Optionally, a movable shaft is fixedly connected to the surface of the adjusting block, and a movable groove is provided on the surface of the reversing cone wheel located on one side of the adjusting roller, and the movable shaft is adapted to the movable groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the crushing roller and the adjusting roller are arranged in opposite directions between the turntable and the partition. The crushing roller and the adjusting roller are driven by the drive rod. Due to the different positions of the meshing reversing cone wheels, the crushing roller and the adjusting roller rotate in opposite directions. As a result, the silicon raw material that has not fallen from the discharge chute can come into contact with the surface of the crushing roller or the adjusting roller. Under the action of their rotation, the silicon raw material moves to the middle position and is squeezed and crushed again. The silicon raw material that is too large and has not fallen will be further crushed to reduce its size, ensuring that all subsequent silicon raw materials fall. Moreover, the silicon raw material can be crushed again under the action of the structure after being fed, which is simpler than the initial processing of silicon raw materials.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1-5 As shown, an industrial silicon furnace feeding device includes an industrial silicon furnace 1, a furnace cover 2 fixedly installed on the top of the industrial silicon furnace 1, and a crushing mechanism installed inside the furnace cover 2. The crushing mechanism includes:

[0029] A separating component is rotatably connected to the inside of the furnace cover 2. The separating component includes a turntable (not shown in the figure) and a partition 31. The turntable and the partition 31 are fixedly connected but do not contact each other.

[0030] It should be noted that a motor is fixedly connected to the top of the furnace cover 2, and a coupling (not shown in the figure) is fixedly connected to one end of the output shaft of the motor. The coupling is fixedly connected to the turntable and the partition 31.

[0031] It should be noted that the design of the turntable is the same as that in the reference patent, and the material feeding position corresponds to the position of the groove on the turntable surface so that the silicon raw material will fall into the industrial silicon furnace 1.

[0032] The furnace cover 2 includes a crushing roller 32 and an adjusting roller 33, both of which are rotatably connected to the inside of the furnace cover 2. Both rollers are positioned between the turntable and the partition 31. A drive cone wheel 34 is fixedly connected to the side of each roller near the furnace cover 2. Two reversing cone wheels 35 are rotatably connected inside the furnace cover 2, meshing with the drive cone wheels 34. A drive rod 36 is rotatably connected inside the furnace cover 2, and is fixedly mounted to the reversing cone wheels 35. The two reversing cone wheels 35 and the drive cone wheels 34 are symmetrically arranged along the same axis.

[0033] The side of the crushing roller 32 near the adjusting roller 33 is aligned with the center of the material feeding position on the surface of the furnace cover 2;

[0034] It should be noted that a motor (not shown in the figure) is fixedly connected inside the furnace cover 2, and a coupling (not shown in the figure) is fixedly connected to one end of the motor output shaft. The surface of the coupling is fixedly connected to one end of the drive rod 36.

[0035] The drive rod 36 causes the two reversing cones 35 to rotate in the same direction. The rotation of the reversing cones 35 drives the drive cone 34 to rotate. The reversing cones 35 and the drive cones 34 are symmetrically arranged relative to the same axis, so the two drive cones 34 rotate in different directions. This causes the crushing roller 32 and the adjusting roller 33 to rotate in different directions, which can bring silicon material between them for extrusion and crush large silicon materials.

[0036] The material feeding plate 37 is fixedly connected to the inside of the furnace cover 2. The side of the material feeding plate 37 away from the industrial silicon furnace 1 is attached to the partition 31. Several material feeding grooves are opened on the surface of the material feeding plate 37.

[0037] In practical application, the industrial silicon furnace 1 feeding device uses a crushing roller 32 and an adjusting roller 33 that rotate in opposite directions between the turntable and the partition 31. The crushing roller 32 and the adjusting roller 33 are driven by a drive rod 36. Due to the different positions of the meshing reversing cone wheel 35, the crushing roller 32 and the adjusting roller 33 rotate in opposite directions. As a result, silicon raw materials that do not fall from the discharge chute can come into contact with the surface of the crushing roller 32 or the adjusting roller 33. Under the action of their rotation, they move towards the middle position and are squeezed and crushed again. Silicon raw materials that are too large and do not fall will be further crushed to reduce their size, ensuring the fall of all subsequent silicon raw materials. Moreover, the silicon raw materials can be crushed again under the action of the structure after feeding, which is simpler than the initial processing of silicon raw materials.

[0038] In some specific implementations, the reversing cone 35 located near the crushing roller 32 is fixedly connected to the drive rod 36, and the reversing cone 35 located near the adjusting roller 33 is slidably connected to the drive rod 36.

[0039] In a further embodiment, a sliding groove 41 is provided inside the individual reversing cone wheel 35, and a sliding rod 42 is fixedly connected to the drive rod 36 near the surface of the reversing cone wheel 35 on that side, and the sliding rod 42 is adapted to the sliding groove 41;

[0040] In some specific implementations, an adjusting block 51 is slidably connected inside the furnace cover 2. The adjusting block 51 is rotatably connected to the surface of the driving cone wheel 34 on the adjusting roller 33. One end of the adjusting block 51 is slidably connected to the surface of the reversing cone wheel 35 on one side of the adjusting roller 33. A limiting gear 52 is slidably connected inside the adjusting block 51. A limiting groove 53 is formed on the surface of the furnace cover 2. A plurality of guide teeth 54 and a plurality of positioning teeth 55 are fixedly connected inside the limiting groove 53. The guide teeth 54 and the positioning teeth 55 are symmetrically arranged relative to the limiting gear 52. The number of guide teeth 54 and positioning teeth 55 is the same, but their widths are different. The width of the guide teeth 54 is greater than the width of the positioning teeth 55, and the ends of the guide teeth 54 away from the limiting gear 52 are flush. The guide teeth 54 and the positioning teeth 55 can simultaneously mesh with the limiting gear 52.

[0041] The limiting groove 53 is provided with guide teeth 54 and positioning teeth 55 of different widths. The ends of both are flush with the end away from the limiting gear 52, and both mesh with the surface of the limiting gear 52. When the limiting gear 52 is positioned between the two, there are meshing teeth with fixed positions on both sides of the limiting gear 52. At this time, the limiting gear 52 cannot rotate. When the limiting gear 52 is located in the longer area on the guide teeth 54, the limiting gear 52 can rotate and slide between the guide teeth 54, which can drive the adjusting block 51 to slide, causing the reversing cone wheel 35 and the driving cone wheel 34 on one side of the adjusting roller 33 to change their positions.

[0042] In a further embodiment, a movable shaft 61 is fixedly connected to the surface of the adjusting block 51, and a movable groove 62 is provided on the surface of the reversing cone wheel 35 located on one side of the adjusting roller 33, and the movable shaft 61 is adapted to the movable groove 62.

[0043] The working principle of this utility model is as follows: The motors on the surface and inside the furnace cover 2 are started. The motors cause the turntable, partition 31, and reversing cone 35 to rotate. The rotation of the reversing cone 35 drives the driving cone 34 to rotate, which in turn causes the crushing roller 32 and adjusting roller 33 to rotate in opposite directions, feeding silicon raw materials into the industrial silicon furnace 1. When the silicon raw materials fall through the turntable, they directly contact the surfaces of the crushing roller 32 and adjusting roller 33, move towards the middle between them, are crushed again, and then fall onto the surface of the discharge plate 37. Under the action of the partition 31, they move and fall through the discharge chute. Inside the industrial silicon furnace 1, larger silicon raw materials will come into contact with the crushing roller 32 and adjusting roller 33 again under the action of the partition 31, and be crushed again until they fall into the industrial silicon furnace 1. When the size of a single batch of silicon raw materials is obviously too large, the limiting gear 52 can be pulled to make the surface of the limiting gear 52 contact only with the guide tooth 54. Rotating the limiting gear 52 will cause the adjusting block 51 to slide, which will drive the adjusting roller 33 to change position, thereby changing the distance between the adjusting roller 33 and the crushing roller 32, so that larger silicon raw materials can enter between them for crushing.

[0044] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
