[0014] The magnesium ore to be reduced is placed on the filter plate. The electric cylinder is controlled to drive the gland downward, sealing it against the worktable surface. The air supply motor then delivers silicon gas from the gas tank through the air supply pipe to the gland. An air inlet is provided on the side of the gland facing the worktable. Silicon gas enters the empty slot through the inlet and reduces the magnesium ore.

DETAILED DESCRIPTION

[0020] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0021] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0022] In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0023] like Figure 1-Figure 4As shown, a silicon thermal method magnesium smelting device consists of a filter plate 1, a groove plate 2, a processing table 3, a support base 4, a protective box 5, a pressure cover 6, a connecting arc plate 7, a control electric cylinder 8, an air supply motor 9, an air supply pipe 10, an air storage box 11, a drain hole 12, a connecting pipe 13, a water supply pump 14, a water supply pipe 15, and a condensing coil 16.

[0024] A processing table 3 is provided on the support base 4, a pressure cover 6 is provided on the processing table 3, the pressure cover 6 is fixedly connected to the processing table 3 through a connecting component, and an air supply component is provided on the back of the support base 4;

[0025] The air supply assembly includes a fixed base arranged on the back, an air storage box 11 is arranged on the fixed base, an air supply motor 9 is arranged on the top of the air storage box 11, and air vents are respectively opened at both ends, the air vents are respectively connected to the air supply pipe 10, and the air supply pipe 10 is respectively fixedly connected to the two ends of the pressure cover 6.

[0026] The pressure cover 6 is provided with a plurality of air inlets on the side facing the processing table 3 .

[0027] An empty slot is provided on the processing table 3, and slot plates 2 are respectively installed at both ends of the empty slot.

[0028] A drainage hole 12 is provided on the surface of the empty groove, and the bottom of the drainage hole 12 is connected to the drainage assembly.

[0029] The drainage assembly includes a connecting pipe 13 connected to the drainage hole 12 , a water pump 14 connected to one end of the connecting pipe 13 , a water pipe 15 connected to the other end of the water pump 14 , and a condensing coil 16 connected to the water pipe 15 .

[0030] Several connectable filter plates 1 are arranged between the trough plates 2. During the reduction process, some debris and water vapor will appear. The debris will fall to the bottom of the filter plate 1 and separate from the reduced magnesium. At the same time, the water vapor will become liquid due to temperature changes and will eventually be discharged from the drainage hole 12.

[0031] The connecting assembly includes a control electric cylinder 8 and a connecting arc plate 7. The control electric cylinder 8 is fixedly mounted on the support base 4. One end of the connecting arc plate 7 is fixedly connected to the pressure cover 6, and the other end is in driving connection with the control electric cylinder 8.

[0033] How it works

[0034] The magnesium ore to be reduced is placed on the filter plate 1, and the electric cylinder 8 is controlled to drive the pressure cover 6 to be pressed down. After it is sealed with the surface of the processing table 3, the air supply motor 9 sends the silicon gas in the air storage box 11 to the pressure cover 6 through the air supply pipe 10. The pressure cover 6 has an air inlet on the side facing the processing table 3. The silicon gas enters the empty slot through the air inlet to reduce the magnesium ore. In the reduction process, water vapor and debris particles will be generated, all of which pass through the filter plate 1 and fall into the gap between the filter plate 1 and the processing table 3. The water vapor eventually forms liquid water and is discharged to the drainage component through the drainage hole 12. When the pressure cover 6 is tightened, silicon gas can be injected into the processing table 3 according to usage requirements. There is no need to open the pressure cover 6 to destroy its sealing environment and affect the reduction of the magnesium ore.
