Description

Technical Field

[0001] This utility model relates to the technical field of batching and mixing devices, specifically a batching and mixing device for the production of metallic silicon. Background Technology

[0002] Metallic silicon is primarily used as an additive in non-ferrous alloys. It is a product smelted from quartz and coke in an electric furnace. It is widely used in the smelting of ferrosilicon alloys as an alloying element in the steel industry and as a reducing agent in the smelting of many metals. In the production of metallic silicon, auxiliary materials such as petroleum coke and coke need to be added and mixed with the main materials to achieve the required production standards and quality. Existing mixing devices include: forced mixers, which use rotating mixing blades to forcibly tumble and shear the material for rapid and uniform mixing; drum mixers, where the rotating drum tumbles the material, achieving mixing through friction and gravity; and plow-type mixers, where high-speed rotating plow blades on the main shaft throw the material up and create a vortex, while simultaneously using shearing blades for efficient mixing. These mixing devices directly pour the ingredients and silicon raw materials into them for direct mixing. They cannot pre-treat the ingredients during mixing. Since the size of coke or petroleum coke is not the same, it is easy to cause uneven mixing of the ingredients, which will affect the subsequent processing of silicon metal and reduce the quality of silicon metal products. At the same time, since the ingredients are directly introduced into the mixing chamber, the mixing time is relatively long. Utility Model Content

[0003] This utility model mainly provides a batching and mixing device for the production of metallic silicon, which solves the problems of existing technology, such as the inability to pre-treat the batching materials, which easily leads to uneven mixing of the batching materials, affecting product quality, and the long mixing time.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A batching and mixing device for silicon metal production includes a mixing chamber, a crushing and mixing chamber connected to the mixing chamber, a silicon raw material feeding channel connected to the mixing chamber, and a batching feeding channel connected to the crushing and mixing chamber. The crushing and mixing chamber is equipped with a crushing mechanism for crushing the batching materials, and a distribution mechanism is located below the crushing mechanism within the crushing and mixing chamber. The mixing chamber is equipped with a stirring mechanism for mixing, and a discharge port is located at the lower end of the mixing chamber, with a discharge gate on the discharge port. Specifically, the discharge end of the crushing and mixing chamber is connected to the feed port of the mixing chamber, thereby introducing the pre-treated batching materials into the mixing chamber. The specific structures of the mixing chamber and the stirring mechanism can adopt existing technologies, as long as the mixing of the materials can be achieved. It is important to note that the batching feed port of the mixing chamber is located at the top, facilitating the distribution mechanism to distribute the materials and then sprinkle them from above. Specifically, the discharge gate can be any type of discharge valve from the existing technology, as long as its technical principle is implemented; for example, several existing mixing devices can be directly used. In operation, silicon raw materials enter the mixing chamber directly through the silicon raw material feed channel and are stirred by the stirring mechanism, thus preventing the silicon raw materials from accumulating in the same position within the mixing chamber. Then, the batching materials enter the crushing and mixing chamber through the batching feed channel. The crushing mechanism first crushes the batching materials, breaking large pieces into smaller particles, improving the uniformity of subsequent mixing. The crushed batching materials are then evenly dispersed by the distribution mechanism and subsequently enter the mixing chamber through the connection structure between the crushing and mixing chamber and the mixing chamber. Inside the mixing chamber, the stirring mechanism operates, thoroughly mixing the silicon raw materials and the crushed and dispersed batching materials until the desired mixing effect is achieved. Finally, the discharge gate is opened, and the uniformly mixed material is discharged from the discharge port, completing the entire batching and mixing process. This structure, with the crushing mechanism pre-crushing the batching materials to refine their particle size, combined with the even dispersion by the distribution mechanism and the powerful stirring by the stirring mechanism, ensures thorough mixing of the silicon raw materials and batching materials. The silicon raw materials, entering separately and being stirred by the stirring mechanism, effectively prevents the silicon raw materials from accumulating in the same position within the mixing chamber, thus avoiding impacting subsequent feeding.

[0006] Furthermore, the crushing mechanism includes an active crushing roller and a driven crushing roller arranged parallel to each other within the crushing and mixing chamber. The active crushing roller drives the driven crushing roller via a gear transmission assembly. A first electric motor is installed on the crushing and mixing chamber to drive the active crushing roller. The first electric motor is connected to a speed reducer via a synchronous toothed belt, which then drives the active crushing roller. The driven roller rotates synchronously in the opposite direction to the active roller via a gear transmission assembly, which uses helical cylindrical gears. With this structure, the first electric motor drives the active crushing roller to rotate, and the gear transmission assembly drives the driven crushing roller to rotate in the opposite direction. The ingredients entering the crushing and mixing chamber are subjected to compression and shearing between the two crushing rollers, achieving crushing and breaking larger particles into smaller particles for easier subsequent mixing.

[0007] Furthermore, a converging discharge channel is provided in the crushing and mixing chamber below the crushing mechanism. With this structure, the converging discharge channel can gather the crushed materials, limiting their falling range and thus facilitating the operation of the distribution mechanism.

[0008] Furthermore, the distribution mechanism includes a mounting frame positioned below the convergence discharge channel. A second motor is mounted on the mounting frame, and a dispersing roller is mounted at the output end of the second motor. The dispersing roller rotates under the drive of the second motor. The power lines of the second and third motors can be housed in the wiring channels of the mounting frame or mixing frame, passing through the mixing chamber, and finally connecting to an external power supply. A sealing structure is provided at the point of penetration. With this structure, when the crushed materials pass through the convergence discharge channel, the second motor drives the dispersing roller to rotate at high speed. The dispersing roller disperses the gathered materials, distributing them evenly and preventing them from clumping together and entering the mixing chamber, thus improving the uniformity of subsequent mixing.

[0009] Furthermore, the stirring mechanism includes a stirring frame disposed within the stirring chamber, a third motor mounted on the stirring frame, a stirring shaft mounted on the third motor, and stirring blades mounted on the stirring shaft. With this structure, the third motor drives the stirring shaft to rotate, causing the stirring blades to rotate accordingly, thus thoroughly mixing the silicon raw materials entering the stirring chamber and the pre-treated ingredients, ensuring uniform distribution of the various materials and guaranteeing the mixing quality of the raw materials for silicon metal production.

[0010] Furthermore, both the second and third motors are equipped with material guide protective shells. This structure serves two purposes: firstly, it prevents material from damaging the motors, extending their lifespan; secondly, it guides the material, preventing accumulation and splashing. Specifically, the upper ends of both the mounting frame and the mixing frame can be designed as arc-shaped, inclined, or conical to effectively prevent material accumulation.

[0011] Beneficial effects: 1. The crushing mechanism breaks down large particles into smaller ones, increasing the contact area between the materials; the distribution mechanism evenly disperses the crushed materials, ensuring good dispersion before they enter the mixing chamber; combined with the thorough mixing by the stirring mechanism, this effectively improves the uniformity of the mixture, thereby enhancing the quality of the silicon metal product; 2. Because the materials have been pre-treated and are in a relatively dispersed state before entering the mixing chamber, the stirring mechanism can more quickly and evenly mix the silicon raw materials and the materials. Compared with traditional stirring devices, this significantly shortens the mixing time, improves production efficiency, and reduces production costs. Attached Figure Description

[0017] The following will provide a more detailed description of the technical solution of a batching and stirring device in the production of metallic silicon, in conjunction with the embodiments of this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in this embodiment, a batching and stirring device for silicon metal production includes a stirring chamber 1, a crushing and mixing chamber 2 connected to the stirring chamber 1, a silicon raw material feeding channel 3 connected to the stirring chamber 1, and a batching feeding channel 4 connected to the crushing and mixing chamber 2. The crushing and mixing chamber 2 is equipped with a crushing mechanism 5 for crushing the batching materials, and a distribution mechanism 6 is provided in the crushing and mixing chamber 2 below the crushing mechanism 5. The stirring chamber 1 is equipped with a stirring mechanism 7 for stirring and mixing, and a discharge port 8 is provided at the lower end of the stirring chamber 1, with a discharge gate on the discharge port 8. Specifically, the discharge end of the crushing and mixing chamber 2 is connected to the feed port of the stirring chamber 1, thereby introducing the pre-treated batching materials into the stirring chamber 1. The crushing mechanism 5 includes an active crushing roller 501 and a driven crushing roller 502 arranged parallel to each other in the crushing and mixing chamber 2. The active crushing roller 501 drives the driven crushing roller 502 through a gear rotation group. The crushing and mixing chamber 2 is equipped with a first motor 503 for driving the active crushing roller 501 to rotate. A converging discharge channel 9 is provided below the crushing mechanism 5 in the crushing and mixing chamber 2. The distribution mechanism 6 includes a mounting frame 601 located below the converging discharge channel 9. A second motor is mounted on the mounting frame 601, and a dispersing roller 602 is mounted on the output end of the second motor. The dispersing roller 602 rotates under the drive of the second motor. The stirring mechanism 7 includes a stirring frame 701 located within the stirring chamber 1. A third motor is mounted on the stirring frame 701, and a stirring shaft is mounted on the third motor. Stirring blades 702 are mounted on the stirring shaft. Both the second motor and the third motor are equipped with guide protective shells.

[0020] In use, silicon raw materials enter the mixing chamber 1 directly through the silicon raw material feed channel 3 and are stirred by the stirring mechanism 7, thus preventing the silicon raw materials from accumulating in the same position in the mixing chamber 1. Then, the batching materials enter the crushing and mixing chamber 2 through the batching feed channel 4. The first motor 503 drives the active crushing roller 501 to rotate, and drives the driven crushing roller 502 to rotate in the opposite direction through the gear rotation group. The batching materials entering the crushing and mixing chamber 2 are subjected to compression and shearing action between the two crushing rollers, realizing crushing and breaking larger particles into smaller particles, improving the uniformity of subsequent mixing. When the crushed ingredients pass through the converging discharge channel 9, the second motor drives the dispersing roller 602 to rotate at high speed. The dispersing roller 602 disperses the gathered ingredients, making them evenly distributed and preventing them from clumping together and entering the mixing chamber 1. Then, it enters the mixing chamber 1 through the connection structure between the crushing and mixing chamber 2 and the mixing chamber 1. Inside the mixing chamber 1, the stirring mechanism 7 operates to fully stir and mix the silicon raw material and the crushed and dispersed ingredients until the desired mixing effect is achieved. Finally, the discharge gate is opened, and the evenly mixed material is discharged from the discharge port 8, completing the entire batching and mixing process. Beneficial effects: The crushing mechanism 5 crushes the ingredients, breaking large particles into smaller ones, increasing the contact area of ​​the materials; the distribution mechanism 6 evenly disperses the crushed ingredients, ensuring good dispersion before they enter the mixing chamber 1; combined with the thorough mixing by the mixing mechanism 7, the mixing uniformity of the ingredients is effectively improved, thereby enhancing the product quality of metallic silicon; since the ingredients have been pre-treated and are in a relatively dispersed state before entering the mixing chamber 1, the mixing mechanism 7 can more quickly and evenly mix the silicon raw materials and ingredients, greatly shortening the mixing time compared to traditional mixing devices, improving production efficiency, and reducing production costs.
