Description

Technical Field

[0001] This utility model relates to the field of industrial silicon, and in particular to an industrial silicon lifting and refining feeding device. Background Technology

[0002] Industrial silicon, also known as metallic silicon, is elemental silicon produced by smelting silica and reducing agents in a submerged arc furnace. It typically contains over 98% silicon. In its solid state, it is dark gray, hard, and brittle, and possesses electrical conductivity. It is widely used in the photovoltaic and semiconductor industries and is a crucial raw material for the production of solar panels and microelectronic products.

[0003] Industrial silicon is smelted in a submerged arc furnace during production. The molten silicon produced is then discharged into a ladle for refining. The slagging refining process requires the addition of a slagging agent. Current feeding devices have the following shortcomings in use:

[0004] Current feeding devices cannot rotate and adjust the feed pipe. After feeding is complete, the feed pipe is too close to the ladle or electric arc furnace, and the high temperature can easily affect the feed pipe, making it inconvenient to adjust the angle for feeding. To address this problem, we propose an industrial silicon ladle refining feeding device. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes an industrial silicon lifting and refining feeding device to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides an industrial silicon ladle refining and feeding device comprising: a feeding hopper;

[0007] A feeding pipe is disposed at the bottom of the feeding hopper and communicates with the feeding hopper;

[0008] A material conveying pipe, one end of which passes through and enters the interior of the material conveying pipe;

[0009] A first connecting component is disposed at one end of the conveying pipe and is connected to the conveying pipe at an interval;

[0010] A second connecting assembly is disposed at the other end of the conveying pipe and connected to the conveying pipe;

[0011] The second connecting component includes a first mounting plate, a first Z-shaped plate, a second Z-shaped plate, a hollow block, and a movable block;

[0012] One end of the first Z-shaped plate is rotatably disposed at the bottom of the first mounting plate, and the other end is rotatably connected to one end of the second Z-shaped plate. The other end of the second Z-shaped plate is rotatably connected to the top of the hollow block. The movable block is disposed at one end of the hollow block, and the bottom of the movable block is connected to the conveying pipe.

[0013] Furthermore, the conveying pipeline includes:

[0014] A feeding pipe has an opening at its top, and one end of the discharge pipe passes through the opening and enters the interior of the feeding pipe;

[0015] An extension tube, wherein the extension tube is sleeved at one end of the conveying pipe;

[0016] Both the extended tube and the conveying tube have protrusions at their top ends;

[0017] The bottom of the moving block is connected to the protrusion at the top of the extended tube, and the conveying tube is connected to the second connecting assembly through the protrusion.

[0018] Furthermore, the second connecting component includes a second mounting plate, a third Z-shaped plate, and a fourth Z-shaped plate;

[0019] One end of the third Z-shaped plate is rotatably connected to the bottom of the second mounting plate, the other end of the third Z-shaped plate is rotatably connected to one end of the fourth Z-shaped plate, and the bottom of the fourth Z-shaped plate is hinged to the protrusion.

[0020] Furthermore, a second electric telescopic rod is provided inside the hollow block, and the output end of the second electric telescopic rod is connected to the top of the movable block.

[0021] Furthermore, a plurality of grooves are provided on the outer wall of one end of the conveying pipe, and the inner wall of the extended pipe is slidably connected to the grooves by a slider.

[0022] Furthermore, a connecting plate is provided at the top of the conveying pipe, and a first electric telescopic rod is provided on one side of the connecting plate. The output end of the first electric telescopic rod is fixedly connected to one end of the extension pipe.

[0023] Furthermore, a fixing block is provided at the bottom of the conveying pipe, and a vibration motor is provided on one side of the fixing block.

[0024] Furthermore, a weighing component is provided inside the conveying pipe.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. When it is necessary to rotate and adjust the feed pipe, the operator can simply push the extension pipe. Under the action of the first and second connecting components, the feed pipe can be rotated, and the angle can be adjusted, which is convenient for the operator to adjust. This keeps the feed pipe and extension pipe away from the lifting bag to prevent them from being affected by high temperature, and at the same time, it is convenient to adjust the feeding.

[0027] Second, by setting up a controller and signal transceiver, the system can calculate the amount of slagging agent required for refining based on the test indicators of the molten silica in the ladle. Then, this feeding device feeds the material according to the feeding time set by the system (when the molten silica in the ladle reaches more than 2 / 3 full), and the amount of material fed is the required amount of slagging agent calculated by the system. After feeding is completed, the feeding pipe automatically retracts to prevent high-temperature burn-off caused by prolonged proximity to the ladle.

[0038] This utility model provides a technical solution in which silica is fed into a conveying pipe 3 via a feeding hopper 1 and a feeding pipe 2, and then fed into a ladle or electric arc furnace for processing. The first mounting plate 11 is fixed to support the conveying pipe 3. When the conveying pipe 3 needs to be rotated and adjusted, the operator simply pushes the extension pipe 4. The first connecting component 10 and the second connecting component 11 allow the conveying pipe 3 to rotate, thus adjusting its angle for easy adjustment. This keeps the conveying pipe 3 and the extension pipe 4 away from the ladle or electric arc furnace to prevent them from being affected by high temperatures, while also facilitating feeding adjustments. The first Z-shaped plate 1002 and the second Z-shaped plate 1003 play a key role in enabling the rotation of the conveying pipe 3.

[0041] Preferably, a second electric telescopic rod 1006 is provided inside the hollow block 1004, and the output end of the second electric telescopic rod 1006 is connected to the top of the moving block 1005.

[0042] Specifically, the second electric telescopic rod 1006 can drive the moving block 1005 to move up and down, thereby driving one end of the material conveying pipe 3 to move up and down, making it convenient to adjust the angle.

A connecting plate 5 is provided on the top of the conveying pipe 3, and a first electric telescopic rod 6 is provided on one side of the connecting plate 5. The output end of the first electric telescopic rod 6 is fixedly connected to one end of the extension pipe 4.

[0046] Specifically, the system uses a weighing component to weigh the slagging agent, a vibrating motor for easy feeding, and a controller and transceiver to calculate the required amount of slagging agent for refining based on the analytical parameters of the molten silica in the ladle. The feeding device then adds the calculated amount of slagging agent when the molten silica in the ladle reaches at least 2 / 3 capacity, according to a pre-set feeding time. After feeding, the feeding pipe automatically retracts to prevent overheating and burn-out from prolonged proximity to the ladle.
