Description

Technical Field

[0001] This utility model relates to the technical field of silicon micropowder production equipment, specifically a feeding device for silicon micropowder production. Background Technology

[0002] Silica powder is a micron-grade inorganic non-metallic material produced from natural quartz or fused quartz through multiple processes including crushing, ball milling (or vibration, air jet milling), flotation, acid washing and purification, and high-purity water treatment. Its main component is silicon dioxide (SiO2), and it possesses excellent properties such as high purity (SiO2 content can reach over 99.9%), high insulation, low coefficient of expansion, high temperature resistance, and good chemical stability. In the production of silicon micropowder, the feeding device is a key piece of equipment to ensure production continuity, stability, and product quality. Silicon micropowder has a fine particle size, poor flowability, and is prone to agglomeration, and requires extremely high purity (impurity content must be controlled at the ppm level), which places stringent demands on the performance of the feeding device. Existing screw feeders have the following technical defects when conveying silicon micro powder: Material blockage and bridging: Due to its fine particle size and high internal friction, silicon micropowder is prone to accumulating at the end of the spiral blades, forming "bridging", which leads to poor material discharge or even blockage. Agglomeration and clumping: During the spiral conveying process, the material is squeezed and rubbed, which easily causes agglomeration. Agglomerated material will affect the uniformity of subsequent processes after being conveyed. Therefore, this patent proposes a feeding device for silicon micropowder production to solve the above problems. Utility Model Content

[0005] Furthermore, the auger conveyor includes a drive motor disposed at one end of the feed pipe, the output end of the drive motor is connected to an auger shaft adapted to the length of the feed pipe, the auger shaft is provided with auger blades adapted to the inner diameter of the feed pipe, and the auger shaft is fixedly connected to a drive gear to form a transmission to the drive gear.

[0006] Furthermore, the torque-increasing component includes a second linkage gear, and a reduction gear is fixedly connected to one end face of the second linkage gear. The transmission gear, the first linkage gear, and the second linkage gear are all gears with the same transmission ratio and mesh sequentially.

[0007] Furthermore, the dispersing component includes a sleeve fitted outside the auger shaft, an output gear for linkage is provided on the sleeve, the output gear meshes with the reduction gear, the transmission ratio of the reduction gear to the output gear is at least , and the sleeve is also provided with a winch for dispersing the raw materials.

[0008] Compared with the prior art, the technical solution of this application has the following beneficial effects: I. This feeding device for silicon micropowder production, by setting up a drive connection between the auger shaft and the dispersing component, can simultaneously disperse the raw materials during the conveying process, thereby avoiding the occurrence of agglomeration or bridging that would lead to poor conveying; at the same time, this transmission method only requires the connection of a single drive source during use, reducing its design and operating costs.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example 1: Please see Figure 1-5 This embodiment of a feeding device for silicon micropowder production includes a support frame 11 for support, a feeding pipe 12 for feeding is provided on the support frame 11, a feeding hopper 13 for adding raw materials is provided at the top of the feeding pipe 12 and communicates with it, an auger conveyor 14 for conveying raw materials is provided on the feeding pipe 12, and a discharge port 15 for discharging is provided at one end of the feeding pipe 12. The auger conveyor 14 is drivenly connected to a dispersing component 2, which is provided at one end of the feeding pipe 12 near the discharge port 15. The dispersing component 2 includes a housing installed on the feeding pipe 12, a transmission gear 21 is provided inside the housing, the transmission gear 21 is linked with the auger conveyor 14, the transmission gear 21 is also meshed with a first linkage gear 22, the first linkage gear 22 is drivenly connected to a torque amplifying component 23, and the torque amplifying component 23 is drivenly connected to a dispersing component 24 for dispersing raw materials to prevent agglomeration and bridging.

[0014] As a preferred technical solution in this embodiment: In actual use, the operator can first put the microsilica powder to be fed into the feeding hopper 13. Under the action of gravity, the microsilica powder will fall into the feeding pipe 12. Then, the operator can start the auger conveyor 14 to transport the microsilica powder to the discharge port 15 for discharge. During this process, the auger conveyor 14 can drive the transmission gear 21 in the dispersing component 2 to drive the first linkage gear 22 to rotate in the opposite direction. The first linkage gear 22 drives the torque amplifying component 23 to rotate in the opposite direction. The torque amplifying component 23 drives the dispersing component 24 to rotate in the opposite direction, so that the dispersing component 24 can generate a rotation opposite to the auger shaft 142, and can form a shearing force opposite to the direction of raw material conveying, thereby ensuring that it achieves a good dispersing effect on the raw material and avoiding the occurrence of agglomeration or bridging.

[0015] The technical effects of the above embodiments are as follows: by setting the auger shaft 142 to be connected to the dispersing component 2, the raw materials can be dispersed at the same time during the material conveying process, thereby avoiding the occurrence of agglomeration or bridging that would lead to poor material conveying; at the same time, this transmission method only requires the connection of one drive source during use, which reduces its design and use costs.

[0016] As a preferred technical solution in this embodiment: the auger conveyor 14 includes a drive motor 141 disposed at one end of the feed pipe 12. The output end of the drive motor 141 is connected to an auger shaft 142 adapted to the length of the feed pipe 12. An auger blade 143 adapted to the inner diameter of the feed pipe 12 is disposed on the auger shaft 142. The auger shaft 142 is fixedly connected to the drive gear 21 to form a transmission to the drive gear 21. In actual use, the auger shaft 142 drives the auger blade 143 to rotate within the feed pipe 12, enabling the raw materials to be conveyed effectively and ensuring its stability during the conveying process.

[0017] As a preferred technical solution in this embodiment: the torque-increasing component 23 includes a second linkage gear 231, and a reduction gear 232 is fixedly connected to one end face of the second linkage gear 231; the transmission gear 21, the first linkage gear 22, and the second linkage gear 231 are all gears with the same transmission ratio and mesh sequentially. This connection method allows for effective adjustment of the rotation direction of the dispersing component 24 during use, so that it can be opposite to the rotation direction of the first linkage gear 22; that is, the rotation direction of the transmission gear 21 is the same as that of the torque-increasing component 23, and the rotation direction of the first linkage gear 22 is the same as that of the dispersing component 24; so that the dispersing component 24 can generate a reverse shearing force with the raw material, ensuring its dispersing effect during use.

[0018] As a preferred technical solution in this embodiment: the dispersing component 24 includes a sleeve 241 sleeved outside the auger shaft 142. An output gear 242 for linkage is provided on the sleeve 241. The output gear 242 meshes with a reduction gear 232, and the transmission ratio between the reduction gear 232 and the output gear 242 is at least 2:1. A winch 243 for dispersing the raw materials is also provided on the sleeve 241. This arrangement ensures that when the reduction gear 232 rotates the output gear 242, the output gear 242 has a greater torque, thereby ensuring a better dispersing effect on the raw materials.
