Description

Technical Field

[0001] This utility model relates to the field of silicon water impurity removal, specifically to a silicon package. Background Technology

[0002] The silicon ladle is used to hold molten silicon and remove impurities outside the electric arc furnace. The top of the silicon ladle has a core structure, which is the main component for removing impurities such as aluminum and calcium in the silicon refining process. The core has ventilation holes. When oxygen is introduced through the ventilation holes, the molten silicon reacts with oxygen to form oxides, which are deposited at the bottom of the silicon ladle, ultimately producing qualified products. The silicon ladle core is the core component of the industrial silicon refining process, and it is also the most easily damaged component, requiring the most frequent maintenance. Currently, the silicon ladle core in the industrial silicon industry is constructed by fully mixing corundum castable with water and casting it.

[0003] The existing core has too few and unevenly distributed vent holes, and the oxygen is introduced too quickly, which prevents the reaction from being fully and effectively carried out. Utility Model Content

[0004] The purpose of this invention is to provide a silicon package.

[0005] This utility model is implemented by the following technical solution:

[0006] A silicon package includes a package body that is frustum-shaped with an opening at the top and an inner diameter at the top that is larger than the inner diameter at the bottom.

[0007] The core is frustum-shaped and cast and fixed to the center of the inner bottom of the package body. Inside the core, from bottom to top, there is a cylindrical air cylinder and two spiral tubes. The bottom of the cylindrical air cylinder is connected to an air inlet pipe that passes through the package body. Several first air pipes are provided between the cylindrical air cylinder and the lower spiral tube. The two ends of the first air pipes are respectively connected to the top of the cylindrical air cylinder and the lower spiral tube. Several second air pipes are provided between the two spiral tubes. The two ends of the second air pipes are respectively connected to the two spiral tubes. Several third air pipes are connected to the upper spiral tube. The third air pipes pass through the top of the core and communicate with the interior of the package body.

[0008] Preferably, the core is made of refractory bricks inside and castable refractory outside.

[0009] Preferably, the first trachea, the second trachea, and the third trachea are all copper tubes.

[0010] Preferably, the diameters of the first trachea, the second trachea, and the third trachea gradually decrease in that order.

[0011] Preferably, the number of the first trachea, the number of the second trachea, and the number of the third trachea gradually increase in sequence.

[0012] The advantages of this invention are: multi-stage oxygen supply, which allows oxygen to be supplied through multiple capillary-like third gas tubes. The number of third gas tubes increases the ventilation distribution and is evenly arranged. While increasing the amount of oxygen, the oxygen is concentrated but at a uniform speed due to the limitation of the tube diameter, which avoids being too fast and allows the silicon water to react fully and effectively.

[0019] 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.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a silicon package includes a package body 1, which is shaped like an inverted frustum with an opening at the top. The inner diameter of the top is larger than the inner diameter of the bottom, which reduces the scouring and burning of the inner wall of the silicon package by the high-temperature silicon water and helps to extend the service life of the silicon package.

[0021] Core 2 is made of inner refractory bricks and outer castable material, and the castable material is corundum casting material.

[0022] The core 2 is shaped like a frustum and is cast and fixed to the center of the bottom of the body 1. Inside the core 2, from bottom to top, there is a cylindrical air cylinder 3 and two spiral tubes 4. The bottom of the cylindrical air cylinder 3 is connected to an air inlet pipe 5 that passes through the body 1. Several first air pipes 6 are provided between the cylindrical air cylinder 3 and the lower spiral tube 4. The two ends of the first air pipes 6 are connected to the top of the cylindrical air cylinder 3 and the lower spiral tube 4, respectively. Several second air pipes 7 are provided between the two spiral tubes 4. The two ends of the second air pipes 7 are connected to the two spiral tubes 4, respectively. Several third air pipes 8 are connected to the upper spiral tube 4. The third air pipes 8 pass through the top of the core 2 and are connected to the interior of the body 1.

[0023] The diameters of the first trachea 6, the second trachea 7, and the third trachea 8 gradually decrease in that order.

[0024] The number of first trachea 6, the number of second trachea 7, and the number of third trachea 8 gradually increase in sequence.

[0025] Oxygen is introduced through the intake pipe 5, collected by the cylindrical air cylinder 3, and then dispersed through several first air pipes 6 to the lower spiral tube 4 for even distribution. After being evenly distributed, it passes through a larger number of second air pipes 7 with smaller diameters and is distributed to the upper spiral tube 4. After being collected, it finally passes through a larger number of third air pipes 8 with even smaller diameters to the silicon water to participate in the reaction.

[0026] The first air pipe 6, the second air pipe 7, and the third air pipe 8 are all copper pipes. When the copper pipes are burned out, it will not affect the product quality. At the same time, the connection operation after the copper pipes are burned out is simple and low in cost.

[0027] Working principle: When this utility model is in use, oxygen is introduced through the air inlet pipe 5, collected by the cylindrical air cylinder 3, and then dispersed through several first air pipes 6 to the lower spiral tube 4 for even distribution. After being evenly distributed, it then passes through a larger number of second air pipes 7 with smaller diameters, and is distributed to the upper spiral tube 4. After being collected, it finally passes through a larger number of third air pipes 8 with even smaller diameters to the silicon water to participate in the reaction.

[0028] Advantages: The multi-stage oxygen supply through the first trachea 6, the second trachea 7 to the third trachea 8, and the oxygen collection through the cylindrical air cylinder 3 and the spiral tube 4, allow oxygen to be supplied through multiple capillary-like third tracheas 8. The multiple third tracheas 8 increase the ventilation distribution and are evenly arranged, increasing the amount of oxygen in the silicon package. At the same time, due to the limitation of the pipe diameter, the oxygen is dense but at a uniform speed, avoiding excessive speed, so that the silicon water can react fully and effectively.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
