[0002] In the industrial silicon smelting industry, it is necessary to study the factors that affect the quality of industrial silicon products during the process of industrial silicon being taken out of the furnace. Therefore, it is necessary to sample and test the samples taken out of the furnace and the silicon bag refining samples respectively. The existing samplers are spoon-shaped or long strip-shaped. The operation method is to insert the sample into the melt and take out the sample after the melt solidifies. However, the sampler is mostly made of cast iron and graphite. Since industrial silicon products require low iron, the cast iron sampler will bring impurities such as iron into the sample, so it is not suitable for industrial silicon sampling. Moreover, since the ore-fired furnace is too large and the temperature is too high, the sampler cannot be directly inserted into the ore-fired furnace for melt sampling. In addition, the sampler is costly and has low strength. When unloading the sample, the sampler will be directly destroyed for sampling, resulting in a low reuse rate and life of the sampler, which leads to an increase in sampling costs.

The push rod 212 is slidably matched with the hole wall of the unloading hole 112. The push rod 212 can extend from the end of the unloading hole 112 away from the melt tank 111 into the unloading hole 112. The end of the push rod 212 away from the plate 211 can abut against the ball valve 12 to push the ball valve 12 to expose the opening 1111 and drive the sample 200 to separate from the melt tank 111 through the ball valve 12; specifically, when the sample 200 is cooled and solidified, the sampler 11 containing the solidified sample 200 is inverted on the sampling platform, and then the push rod 212 of the unloader 21 is extended The push rod 212 is inserted into the discharge hole 112, so that the push rod 212 can slide up and down in the vertical direction relative to the hole wall of the discharge hole 112. When the push rod 212 moves downward along the hole wall of the discharge hole 112 until it abuts against the ball valve 12, the push rod 212 can continue to move downward by applying pressure to the flat plate 211 to push the ball valve 12 to expose the opening 1111, so that the ball valve 12 drives the sample 200 to move downward relative to the solution tank 111, thereby separating the ball valve 12 and the sample 200 from the solution tank 111. After taking out the sample 200 and the ball valve 12, the push rod 212 is separated from the hole wall of the discharge hole 112, the sample 200 can be tested, and the ball valve 12 and the material extractor can be cleaned and wait for the next use.
[0036] According to an embodiment of the present invention, the push rod 212 is slidably connected to the hole wall of the discharge hole 112. After the sampling is completed, the push rod 212 and the hole wall of the discharge hole 112 do not need to be separated.
[0037] In one embodiment, a groove 2121 for accommodating the ball valve 12 is provided at one end of the push rod 212 away from the flat plate 211, and the groove wall of the groove 2121 is used to abut against the ball valve 12; specifically, in order to increase the contact area between the push rod 212 and the ball valve 12, so that the push rod 212 can more easily push the ball valve 12 to leak out of the opening 1111, and also to protect the ball valve 12 from being damaged during the sampling process, a groove 2121 for accommodating the ball valve 12 is provided at one end of the push rod 212 away from the flat plate 211, and the groove wall of the groove 2121 is used to abut against the ball valve 12, thereby pushing the ball valve 12 so that the ball valve 12 drives the sample 200 to separate from the solution tank 111, and completing the sampling.
[0038] In one embodiment, the shape of the groove 2121 is adapted to the shape of the side of the ball valve 12 facing the groove 2121; specifically, in order to protect the ball valve 12 from being damaged during the sampling process and enable the ball valve 12 to be reused multiple times, the shape of the groove 2121 is adapted to the shape of the side of the ball valve 12 facing the groove 2121, the ball valve 12 is a spherical structure, and the groove 2121 is an arc structure matching the spherical structure, so that the groove 2121 and the ball valve 12 can fit together during unloading to prevent damage to the ball valve 12.
[0039] In one embodiment, the unloading mechanism 2 also includes an elastic member 22, and the elastic member 22 is connected to the flat plate 211, so that when the push rod 212 extends from the end of the unloading hole 112 away from the dissolving tank 111 into the unloading hole 112, the elastic member 22 abuts against the sampler 11; specifically, when the push rod 212 moves downward along the hole wall of the unloading hole 112 to abut against the ball valve 12, one side of the elastic member 22 is connected to the flat plate 211, and the other side of the elastic member 22 abuts against the sampler 11. By setting the elastic member 22, the purpose of elastic unloading can be achieved, and the flat plate 211 can be prevented from directly contacting the sampler 11, so as to avoid damage to the sampler 11 when pressure is applied to the flat plate 211, thereby extending the service life of the sampler 11, allowing the sampler 11 to be reused many times, thereby reducing the sampling cost.
[0040] In one embodiment, the elastic member 22 includes a rubber pad; specifically, the rubber pad is connected to the flat plate 211, and the size of the rubber pad can be the same as the size of the flat plate 211. The elastic force of the elastic member 22 can achieve the purpose of elastic unloading, prevent the flat plate 211 from directly contacting the sampler 11, and avoid damaging the sampler 11 when pressure is applied to the flat plate 211. When pressure is applied to the flat plate 211, the rubber pad will be compressed, and the height of the rubber pad compression is the same as the height of the push rod 212 moving downward. After the sampling is completed, the pressure disappears and the rubber pad returns to its original state. In this embodiment, the elastic member 22 can also be a nylon pad or other elastic structure, which is not limited in this embodiment.

[0042] In one embodiment, the melt tank 111 is an arc-shaped structure; specifically, in order to improve the unloading efficiency of the industrial silicon ore-fired furnace front feeder 100, the melt tank 111 is set to an arc-shaped structure, which can increase the demolding slope of the solidified sample 200, reduce the demolding resistance, and make the solidified sample 200 easier to separate from the melt tank 111, thereby improving the unloading efficiency.
[0043] In one embodiment, an opening 1111 is provided at the bottom of the solution tank 111; specifically, since the solution tank 111 is an arc-shaped structure, the opening 1111 is provided at the bottom of the solution tank 111, so that the ball valve 12 can automatically slide along the inner wall of the solution tank 111 to the opening 1111 at the bottom by its own gravity, and the size of the opening 1111 is smaller than the diameter of the ball valve 12, so that the ball valve 12 can be accurately stuck at the opening 1111 and cannot move or fall off. There is no need to deliberately place the ball valve 12 at the opening 1111, which can effectively improve the sampling efficiency.
[0044] In one embodiment, an annular groove 113 is provided on the outer wall of the sampler 11; specifically, the sampler 11 is a cylindrical structure, which is easy to process, and in order to facilitate the sampling device to clamp the sampler 11, an annular groove 113 is provided on the outer wall of the sampler 11. The sampling device clamps the inner wall of the annular groove 113 so that the sampling device and the sampler 11 are kept fixed, which facilitates the sampler 11 to be sent to the silicon outlet of the electric arc furnace to receive the sample 200.
