Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon preparation, in particular to an automatic refining device. Background Art

[0002] Industrial silicon, also known as semi-metallic silicon, is a trade name that emerged in the mid-1960s. Silicon metal is smelted in a submerged arc furnace using silica and a carbonaceous reducing agent. Its main component, silicon, accounts for approximately 98%, with other impurities such as iron, aluminum, and calcium. Currently, the refining process for industrial silicon is manual, with a constant turnover of personnel and a long learning curve. Without standardized refining process data, the process is significantly influenced by operator experience, leading to fluctuations in product quality.

[0003] In this regard, the existing technology (CN220283630U) discloses a silicon bag oxygen blowing refining device, which controls the air intake volume by changing the temperature, thereby achieving precise control of the temperature and avoiding phenomena such as bag penetration, bag hanging, bag deadness, and excessive calcium caused by excessively high or low temperature.

[0004] However, the above-mentioned existing silicon refining device has the following technical problems during use: during the silicon refining process, the reaction degree is monitored only by temperature changes to determine the oxygen flow rate, and the factors considered are relatively simple. In addition, the temperature sensor is set in the silicon package. Once the temperature sensor is damaged, it may cause greater losses to the silicon package, and it is not stable enough.

Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention. Example

[0032] See also Figure 1-2 The automatic refining device includes a ladle trolley 5 and a silicon ladle 1. A discharge nozzle 101 is provided on one side of the top of the silicon ladle 1. The silicon ladle 1 is suspended on the fixed hanging ear of the ladle trolley 5, and its bottom is supported on the bottom plate of the ladle trolley 5. The moving wheels 7 of the ladle trolley 5 are set on the track. An automatic tipping machine 3 is provided on one side of the ladle trolley 5 and the silicon ladle 1. The upper end of the silicon ladle 1 is suspended on the fixed hanging ear of the ladle trolley 5, and its bottom is supported on the bottom plate of the ladle trolley 5. The ladle trolley 5 is dragged and moved to the automatic tipping machine 3 by the winch wire rope. The hanging ring of the silicon ladle 1 cooperates with the lifting ear of the automatic tipping machine 3, which can facilitate the material in the silicon ladle 1 to be tilted at a certain angle and then unloaded.

[0033] An oxygen injection machine is provided at the bottom of the silicon bag 1 through an oxygen supply pipe 4, a fixed temperature measuring device 2 is provided on the outside of the silicon bag 1, and a weighing sensor 6 is provided inside the moving wheel 7 of the bag lifting vehicle 5; the oxygen injection machine and the fixed temperature measuring device are fixedly arranged on the outside of the bag lifting vehicle, and the oxygen injection machine delivers oxygen to the oxygen supply pipe 4 through a long and soft leather hose. The fixed temperature measuring device is adjusted at an angle to irradiate the inside of the silicon bag, so as to monitor the internal material temperature of the silicon bag. The weight change of the material can be timely known through the setting of the weighing sensor.

[0034] The oxygen injection machine, the fixed temperature measuring device 2 and the weighing sensor 6 are all connected through the host. The host calculates the amount of gas that needs to be input into the silicon bag 1 by the oxygen injection machine based on the temperature change and the weighing change. By monitoring the data through the host, human detection of data can be avoided and errors can be reduced.

[0035] Furthermore, in this embodiment, the ladle lifting vehicle 5 is mounted on a track laid on the ground, and the moving wheel 7 includes two grooved wheels and one flat wheel, and weighing sensors are fixedly installed in the axles of the grooved wheels and the flat wheels; the grooved wheels are used to keep the ladle lifting vehicle on the track and have an anti-pry function, and the flat wheels can keep the ladle lifting vehicle moving, and weighing sensors are installed in the axles of the grooved wheels and the flat wheels, which can weigh the material inside the silicon bag set on the ladle lifting vehicle.

[0036] Furthermore, in this embodiment, the fixed temperature measuring device 2 includes a temperature measuring camera and an infrared sensor. The temperature measuring camera and the infrared sensor are fixedly arranged on the column at the refining position on the second floor of the workshop and the angle is adjusted. The height from the ground of the second-floor platform is about 2 meters. An automatic protective cover is set on the outside of the temperature measuring camera. When the ladle car 5 pulls the silicon bag 1 and moves it to the refining position on the track, the infrared sensor detects the position of the silicon bag 1, and the automatic protective cover on the outside of the temperature measuring camera opens to measure the temperature of the silicon water in the silicon bag. The setting of the ladle car weighing sensor can timely know the change in material weight.

[0037] Furthermore, in this embodiment, the oxygen supply pipe 4 includes a connecting pipe 401, a hose 402, a straight pipe 403, a telescopic pipe 407, a bent pipe 408 and a connector 409. The connecting pipe 401, the hose 402, the straight pipe 403, the telescopic pipe 407, the bent pipe 408 and the connector 409 are fixed and connected in sequence.

[0038] The connecting pipe 401 passes through the bottom of the silicon bag 1 and extends into the interior thereof; the hose 402, the straight pipe 403 and the telescopic pipe 407 are located in the chute 501 opened on the bottom plate of the bag lifting vehicle 5; one end of the bent pipe 408 is located in the chute 501, and the other end is located outside the bottom plate of the bag lifting vehicle 5, and is fixedly connected to the oxygen injection machine through the connector 409 and the long soft leather hose.

[0039] At the same time, in this embodiment, the outer walls of both ends of the straight tube 403 are respectively provided with a fixed retaining ring 404 and a movable retaining ring 406, and the middle end is provided with a spring 405.

[0040] The fixed retaining ring 404 is fixed in the mounting groove 502 and maintains a sliding connection with the straight pipe 403 ; the movable retaining ring 406 is fixedly connected to the straight pipe 403 and moves as the straight pipe 403 moves.

[0041] It should be pointed out that the oxygen injection machine is not shown in the figure, and the automatic tilting machine 3 is a lifting device. Both are existing technologies that can be purchased and used directly, and their structures are not described in detail here.

[0042] Specifically, during use, when the material in the silicon bag 1 needs to be unloaded, the automatic tilting machine 3 is started to tilt the material in the silicon bag 1 to a certain angle before unloading.

[0043] When the silicon bag 1 tilts, due to its position change, the connecting pipe 401 is fixedly connected to the silicon bag 1. The silicon bag 1 drives the connecting pipe 401 to move, and the connecting pipe 401 pulls the flexible pipe 402 and the straight pipe 403 to move together. The bent pipe 408 is fixed in the chute 501. When the straight pipe 403 moves, it pulls the telescopic pipe 407 to stretch and lengthen. Under the action of the telescopic pipe 407, the connecting pipe 401 can move with the silicon bag 1 without affecting the connection between the bent pipe 408 and the oxygen injector.

[0044] At the same time, when the straight tube 403 moves, the movable retaining ring 406 moves along with the movement of the straight tube 403, causing the spring 405 to be compressed;

[0045] After the silicon bag 1 is reset, the reaction force of the spring 405 and the telescopic tube 407 pulls the connecting tube 401, the hose 402 and the straight tube 403 toward the chute position, so that the pipes are reset.

[0046] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structures, equivalent processes, or equivalent functional transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of protection of the present utility model patent.
