[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example: Refer to Figures 1-3 A device for screening vitreous material from lunar soil, comprising:

[0035] Box 1, with a grinding chamber and a separation chamber formed inside the box 1, the feed end of the grinding chamber is used to introduce lunar soil;

[0036] Grinding components, set inside the grinding chamber, are used to grind lunar soil to prepare a mixture;

[0037] A blower 2 is installed inside the housing 1. The output end of the blower 2 forms a sorting channel inside the housing 1. The feed end of the sorting channel is connected to the discharge end of the grinding chamber. There are at least two discharge ends of the sorting channel. Several discharge ends are arranged in the housing 1 from top to bottom. The discharge ends cooperate with the blower 2 to sort the mixed material into glass stone mixture and stone. The discharge end located at the top is used to pass the glass stone mixture into the separation chamber, and the other discharge ends are used to pass the stone out of the housing 1.

[0038] The screening component includes a centrifuge tank 3 that rotates within the separation chamber. The centrifuge tank 3 generates centrifugal force within the separation chamber to separate the glass-stone mixture into glass material and stone material. The glass material exits the housing 1 through the centrifuge tank 3.

[0039] Reference Figure 2 and Figure 3 This invention introduces lunar soil into the grinding chamber of housing 1, where grinding media are used to grind the lunar soil, reducing materials of different densities to the same volume. The ground mixture is then sorted through a sorting channel connected to the discharge end of the grinding chamber. A blower 2 acts on the mixture, and it is sorted from top to bottom along the sorting channel by gravity. Glass particles and plagioclase with lower density (smaller mass per volume) and smaller mass per unit volume are fed to the top discharge end, while the remaining high-quality stone particles are discharged from the other discharge ends of housing 1. The top discharge end then feeds the glass-stone mixture into a centrifuge tank 3, where centrifugation further separates the larger stone particles from the smaller glass particles. Finally, the glass particles are discharged from the centrifuge tank 3, while the stone particles remain inside. This process of graded recovery of lunar soil not only effectively achieves full recovery of glass materials but also improves the applicability and efficiency of lunar soil material recovery.

[0040] Furthermore, it also includes:

[0041] The first tank 4 is set inside the box 1 to form a grinding chamber. The top side of the first tank 4 is connected to a feed pipe 22, and one end of the feed pipe 22 extends out of the box 1 and communicates with the outside.

[0042] The second tank 5 is located inside the box 1 to form a separation chamber, and the centrifuge tank 3 is transferred to the second tank 5;

[0043] The sorting pipe 6 has a V-shaped structure. Both ends of the sorting pipe 6 are connected and fixed to the first tank 4 and the second tank 5, respectively. The bent section of the sorting pipe 6 has a horizontal bottom end. One side of the bent section is connected to a blower 2 through a first pipe 7. The blower 2 is located below the first tank 4 and is arranged opposite to the second tank 5. The bottom end of the bent section is connected to at least one second pipe 8, which is used to pass the stone out of the box 1.

[0044] Reference Figure 2 By grinding lunar soil inside the first tank 4, it is understood that a filter screen (not shown in the figure) is installed at the end of the sorting pipe 6 connected to the first tank 4. Only when the volume of the ground lunar soil meets the filter pore size of the filter screen will the ground mixture be introduced into the sorting pipe 6. Then, using the V-shaped structure of the sorting pipe 6, the fan 2 at the bottom vents through the first pipe 7 to the bent section of the sorting pipe 6. Under the action of the wind, the heavy stones fall into the second pipe 8 and exit the box 1. The light glass and oblique stones enter the part of the sorting pipe 6 opposite to the first pipe 7 and are introduced into the second tank 5. The centrifuge tank 3 installed in the second tank 5 performs centrifugal separation to further separate the glass, realize the full recovery of glass materials in the lunar soil, and classify and screen the lunar soil according to the type of material, thereby improving the utilization efficiency of lunar soil.

[0045] Furthermore, the portion of the sorting pipe 6 that connects to the second tank 5 is located on the same axis as the first pipe 7.

[0046] Reference Figure 3 The first pipe 7 and the sorting pipe 6 are set on the same axis. Since the blower 2 and the second tank 5 are set opposite each other, the wind force output by the blower 2 directly corresponds to the sorting of the ground mixture, thereby improving the efficiency of the lighter glass material and plagioclase material entering the second tank 5.

[0047] Furthermore, the grinding parts include:

[0048] Grinding roller 9 is rotatably fitted inside the grinding chamber;

[0049] The first driving component is mounted on the housing 1. The driving end of the first driving component is connected to the grinding roller 9. The driving end of the first driving component is connected to the centrifuge tank 3 through a transmission component, which is an acceleration transmission structure.

[0050] Reference Figure 2The first driving component drives the grinding roller 9 to rotate and grind the lunar soil. The driving end of the first driving component is connected to the centrifuge tank 3 through the transmission component. The acceleration transmission structure is used to improve the output speed of the driving end of the first driving component and ensure the centrifugal effect generated by the rotation of the centrifuge tank 3.

[0051] Furthermore, the first driving component includes:

[0052] The drive motor 10 is fixed to the outer wall of the housing 1. The output shaft of the drive motor 10 is fixed to the first rotating rod 11 through a coupling. The first rotating rod 11 is rotated inside the housing 1 and one end extends into the first tank 4. The end of the first rotating rod 11 extending into the first tank 4 is fixed to the axis of the eccentric wheel 12. The eccentric wheel 12 is rotated to the first tank 4. One end of the eccentric shaft is fixed to the bottom surface of the eccentric wheel 12, and the other end of the eccentric shaft is fixed to the grinding roller 9.

[0053] Furthermore, the bottom of the first tank 4 has an arc-shaped structure, and the grinding roller 9 is inclinedly arranged inside the first tank 4 and slides in contact with the center of the bottom of the first tank 4.

[0054] Reference Figure 2 , Figure 3 The connecting end of the sorting pipe 6 and the first tank 4 is located above the lowest end of the arc-shaped structure. The feed pipe 22 is connected to the top side of the first tank 4. When lunar soil is introduced through the feed pipe 22, the drive motor 10 drives the first rotating rod 11 to rotate. The eccentric wheel 12 rotates and drives the grinding roller 9 to rotate to grind the lunar soil. The grinding roller 9 slides in contact with the inner wall of the arc-shaped bottom end of the first tank 4. As grinding progresses, the mixed material gradually accumulates. When it accumulates to the height connected to the sorting pipe 6, it is introduced into the sorting pipe 6. The eccentric wheel 12 drives the grinding roller 9, which is inclined and whose bottom end slides in contact with the center of the first tank 4, to rotate, thereby improving the grinding effect.

[0055] Furthermore, the transmission components include:

[0056] A pair of drive wheels 13, with different diameters, wherein the drive wheel 13 with a larger diameter is fitted and fixed on the first rotating rod 11, and the drive wheel 13 with a smaller diameter is fitted and fixed on the second rotating rod 14. One end of the second rotating rod 14 is rotatably connected to the box body 1, and the other end of the second rotating rod 14 extends into the second tank body 5 and is fixedly connected to the centrifuge tank 3. A belt 15 is used to drive the pair of drive wheels 13.

[0057] The drive motor 10 rotates the first rotating rod 11, which drives the large transmission wheel 13 to rotate. The large transmission wheel 13 drives the small transmission wheel 13 to rotate via the belt 15, and then drives the centrifuge tank 3 via the second rotating rod 14. This accelerates the transmission mechanism, increases the speed of the drive end of the drive motor 10, improves the centrifugal effect, and speeds up the efficiency of further sorting of the glass stone mixture.

[0058] Furthermore, the top of the centrifuge tank 3 is an open end. The centrifuge tank 3 is connected to the sorting channel through the second tank body 5. The bottom of the centrifuge tank 3 is an inverted frustum structure and there is a gap between it and the second tank body 5. A material distribution hopper 16 is integrally formed at the bottom axis of the centrifuge tank 3. The material distribution hopper 16 is set inside the centrifuge tank 3. When the centrifuge tank 3 rotates, the glass material moves along the direction of the material distribution hopper 16 under centrifugal action and passes out of the second tank body 5 through the material distribution hopper 16. The bottom of the second tank body 5 is connected to the outside through the connecting pipe 17.

[0059] In this technical solution, the second tank 5 is a sealed tube. One end of the second rotating rod 14 extends into the second tank 5 and is fixedly connected to the centrifuge tank 3. A sealing ring 21 is fixedly connected to the top surface of the second tank 5. The sealing ring 21 is sleeved around the second rotating rod 14 and slides in contact with the second rotating rod 14. The centrifuge tank 3 is rotated by the second rotating rod 14, and the glass-stone mixture is centrifugally separated. The larger orthorhombic stones gradually move to the periphery of the inner wall of the centrifuge tank 3 under the centrifugal action, while the glass material is squeezed towards the axis of the centrifuge tank 3 under the pressure of the orthorhombic stones. The glass material at the axis is then discharged from the second tank 5 through the distribution hopper 16 and collected by the connecting pipe 17. A valve 23 is provided on the connecting pipe 17 for opening and closing the connecting pipe 17 to collect the glass material.

[0060] In one embodiment of the present invention, the second tank 5 is a common sealed tank equipped with an openable and closable sealing door, which is existing technology and will not be described in detail. After the glass material separation is completed, the separated orthorhombic material can be recovered by opening the second tank 5, so as to make full use of lunar soil material.

[0061] Furthermore, the distributing hopper 16 has a frustum-shaped structure, with the top of the distributing hopper 16 extending vertically upwards. A hollow cavity is formed inside the distributing hopper 16, and the two ends of the hollow cavity are connected to the centrifuge tank 3 and the second tank body 5, respectively. A gap is provided between the outer wall of the distributing hopper 16 and the inner wall of the centrifuge tank 3. One end of the second rotating rod 14 extends into the second tank body 5 and into the distributing hopper 16. Several fixed rods 18 are fixedly connected at equal intervals between the second rotating rod 14 and the distributing hopper 16.

[0062] By setting the distribution hopper 16 as a frustum-shaped structure, when the centrifuge tank 3 rotates centrifugally, the glass material moves towards the axis of the centrifuge tank 3. As the glass material gradually accumulates and increases in height, it rises along the inclined surface of the distribution hopper 16 and finally enters the hollow cavity through the top opening of the distribution hopper 16. Through the gap between the fixing rods 18, it passes through the hollow cavity into the second tank 5 and exits the box 1 through the connecting pipe 17 set at the bottom of the second tank 5, thus completing the sorting and collection of the glass material. By setting the distribution hopper 16, the purity of the separated glass material can be effectively improved, and the recovery effect is enhanced on the basis of fully recovering the glass material.

[0063] Furthermore, a slider 19 is fixed to the outer periphery of the centrifuge tank 3, and a slide rail 20 is provided around the inner wall of the second tank 5. One end of the slider 19 extends into the slide rail 20 and slides with the slide rail 20.

[0064] By circumferentially installing a slide rail 20 on the inner wall of the second tank 5, the second tank 5 is fixed to the box 1. The connecting pipe 17 passes through the second tank 5 and the box 1. When the second rotating rod 14 rotates the centrifuge tank 3, the slider 19 and the slide rail 20 maintain the stability of the centrifugal force.

[0065] The working process of this embodiment is as follows:

[0066] After the lunar soil is fed into the feed pipe 22, the drive motor 10 is started to rotate the first rotating rod 11, which drives the eccentric wheel 12 and the transmission wheel 13 to rotate. At the same time, the second rotating rod 14 and the eccentric wheel 12 rotate. The eccentric wheel 12 rotates the grinding roller 9 to grind the lunar soil. After grinding, the mixture is fed into the sorting pipe 6. The blower 2 separates the materials with different densities. The stone material is discharged through the second pipe 8. The glass-stone mixture is fed into the second tank 5 through the sorting pipe 6 and falls into the centrifuge tank 3. The second rotating rod 14 rotates the centrifuge tank 3 to further separate the glass-stone mixture, resulting in glass material located at the axis of the centrifuge tank 3 and stone material located on the inner wall of the centrifuge tank 3. As the glass material accumulates, it enters the hollow cavity at the top of the distribution hopper 16. The pure glass is fed into the second tank 5 through the distribution hopper 16 and discharged from the box 1 through the connecting pipe 17. The remaining rhombic stone material is stored in the centrifuge tank 3. After the separation is completed, the second tank 5 is opened to take out the rhombic stone material.
