[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A reaction device for producing highly stable silane compounds, comprising: Figure 1 , Figure 2 and Figure 3As shown, a structural shell 1 is hinged with a first reaction shell 11 in the structural shell 1, a transfer plate 111 is movably connected to the bottom of the first reaction shell 11, a heating block 112 is arranged at the bottom of the transfer plate 111, and an opening and closing plate 113 is arranged on the side of the first reaction shell 11, and the opening and closing plate 113 is movably connected to the first reaction shell 11.

[0021] A first arc rail 13, a second arc rail 14, a third arc rail 15 and a fourth arc rail 16 are arranged on the inner side of the structural housing 1. The axis of the first arc rail 13 coincides with the structural housing 1. A first slider 131 is arranged in each first arc rail 13. Each first slider 131 is connected to the second arc rail 14. The second arc rail 14 can slide on the first arc rail 13 to achieve the up and down displacement of the second arc rail 14. In the channel, a translation telescopic rod 142 is provided, and the two ends of the translation telescopic rod 142 are connected to the second sliders 141. The translation telescopic block can be extended and retracted according to the corresponding position of the second slider 141. The translation telescopic block is connected to the transfer plate 111. When the translation telescopic rod 142 changes with the position of the two second sliders 141, the movement of the translation telescopic rod 142 drives the transfer plate 111 to move relative to the first reaction shell 11, thereby driving the magnesium silicide on the top of the transfer plate 111 to move out of the first reaction shell 11; Two third circular arc slide rails 15 are arranged above the second circular arc slide rail 14. The third circular arc slider is arranged perpendicular to the second circular arc slide rail 14. A third slider 151 is arranged in each third circular arc slide rail 15. One end of a connecting rope 152 is connected to the two third sliders 151. The other end of the connecting rope 152 is hinged to the opening and closing plate 113, so that the third slider 151 can control the opening and closing plate 113 to swing relative to the first reaction shell 11 through the movement in the up and down directions. The opening and closing plate 113 can swing relative to the first reaction shell 11. After the opening and closing plate 113 swings, a gap appears at the first reaction shell 11 due to the swinging of the opening and closing plate 113. Therefore, when the transfer plate 111 is moved out of the first reaction shell 11, the magnesium silicide on the top surface of the transfer plate 111 will not contact the first reaction shell 11, thereby realizing the stable removal of the magnesium silicide on the top surface of the transfer plate 111; A second screw slider 143 and a third screw slider 153 are respectively provided at the second slider 141 and the third slider 151. A linkage screw 17 is sleeved in the second screw slider 143 and the third screw slider 153. The linkage screw 17 is inclined. A vertical rod 18 is vertically provided on the outer side of the linkage screw 17. By controlling the vertical rod 18 to move along the axis of the vertical rod 18, when the vertical rod 18 moves along the axis of the vertical rod 18 toward the bottom of the structural shell 1, the connecting rope 152 connected to the second slider 141 can be controlled to move downward as a whole, so that the opening and closing plate 113 loses the tension of the connecting rope 152, and the third slider 151 can be controlled to connect the translation telescopic rod 142 to drive the transfer plate 111 to move toward the bottom of the first reaction shell 11; On the contrary, when the vertical rod 18 moves along the axis of the vertical rod 18 toward the top of the structural shell 1, the connecting rope 152 connected to the second slider 141 can be controlled to move upward as a whole, so that the opening and closing plate 113 is driven to swing upward by the tension provided by the connecting rope 152, and the third slider 151 connected to the translation telescopic rod 142 can be controlled to drive the transfer plate 111 to move in a direction away from the bottom of the first reaction shell 11.

[0022] like Figure 4 As shown, an absorption rod 2 is arranged in the first reaction shell 11, a symmetrical absorption through hole 21 is arranged on the side of the absorption rod 2, a partition rod 22 is arranged inside the absorption rod 2, and a symmetrical partition block 23 is arranged on the side of the partition rod 22. The partition block 23 covers and separates the absorption through hole 21 as the partition rod 2 rotates. A plurality of discharge pipes 24 are arranged on the side of the partition rod 2. A uniform distribution disk 25 is arranged at the bottom of the absorption rod 2. The uniform distribution disk 25 includes an arc disk 251 and a guide disk 252. The two arc disks 251 are symmetrically arranged at the bottom of the absorption rod 2 with the absorption rod 2 as the center, and the two guide disks 252 are symmetrically arranged at the bottom of the two arc disks 251 with the absorption rod 2 as the center. The arc disk 251 and the guide disk 252 are both arc-shaped in shape. The absorption rod 2 can drive the uniform distribution disk 25 to move up and down, and can drive the guide disk 252 to rotate when the absorption rod 2 rotates. When the guide disk 252 rotates, it can control The positional relationship between the guide disk 252 and the arc disk 251, the change of the positional relationship between the guide disk 252 and the arc disk 251 can realize the connection between the top and the bottom of the uniformly distributed disk 25. The guide disk 252 and the arc disk 251 in the first reaction shell 11 are both provided with a connecting port that is not covered by the arc disk 251 and the guide disk 252 in the same plane. The rotation of the guide disk 252 can make the connecting port of the arc disk 251 and the guide disk 252 in the same plane be compensated by the arc disk 251 and the guide disk 252, thereby realizing the isolation of the top and the bottom of the uniformly distributed disk 25 with the uniformly distributed disk 25 as the boundary. When gas absorption and supply are being performed, the partition block 23 is moved out of the absorption through hole 21, and when gas absorption and supply are not being performed, the partition block 23 covers the absorption through hole 21. The relative position change of the absorption through hole 21 and the partition block 23 inside the absorption rod 2 can absorb and supply the airflow in the top area of ​​the uniform distribution plate 25, so that the isolation of the area inside the first reaction shell 11 by the uniform distribution plate 25 can reduce the absorption of magnesium powder and silicon powder at the bottom of the uniform distribution plate 25 while absorbing the floating silicon powder dust and magnesium powder dust in the top area of ​​the uniform distribution plate 25 when the absorption through hole 21 absorbs the airflow, thereby reducing the waste of raw materials. When the first reaction shell 11 needs to be supplied with gas, the connection of the uniform distribution plate 25 to the area inside the first reaction shell 11 can facilitate the gas to flow into the bottom of the uniform distribution plate 25, so that the magnesium powder and silicon powder can react under heating; The discharge pipe 24 connected inside the absorption rod 2 can input raw materials from the outside into the top of the transfer plate 111 at the bottom of the first reaction shell 11. At the same time, the rotation of the absorption rod 2 can achieve a certain degree of uniform arrangement of magnesium powder and silicon powder. A uniformly distributed groove 26 is provided at the bottom of the guide plate 252. When the guide plate 252 is close to the top of the transfer plate 111, the magnesium powder and silicon powder on the top of the transfer plate 111 can enter the uniformly distributed groove 26 while the guide plate 252 rotates. When the guide plate 252 rotates, different raw materials can change their relative positions in the uniformly distributed groove 26, thereby further achieving the mixing of the magnesium powder and silicon powder on the top of the transfer plate 111, so that the magnesium powder and silicon powder can react more evenly during the reaction, thereby obtaining the target product to the greatest extent.

[0023] like Figure 5 As shown, a fourth arc slide rail 16 is arranged above the second arc slide rail 14, and the fourth arc slide rail 16 is arranged parallel to the second arc slide rail 14. A fourth slider 161 is arranged in the fourth arc slide rail 16, and a scraper plate 3 is connected to the fourth slider 161. The side of the scraper plate 3 closest to the first reaction shell 11 is arranged in an arc shape, and a scraper block 31 is arranged on the arc-shaped side of the scraper plate 3 and is hinged to the arc-shaped side of the scraper plate 3. The scraper block 31 can swing relative to the scraper plate 3, so that when the bottom surface of the scraper plate 3 contacts the magnesium silicide on the top surface of the transfer plate 111, the swing of the scraper block 31 can more effectively scrape the magnesium silicide on the top surface of the transfer plate 111, so as to better realize the cleaning of the top surface of the transfer plate 111, and at the same time ensure that as much magnesium silicide as possible is obtained and the loss of magnesium silicide is reduced; A dust removal block 8 is provided on the top surface of the scraping plate 3, and the dust removal block 8 corresponds to one side of the scraping block 31 of the scraping plate 3. When the scraping plate 3 and the scraping block 31 jointly scrape the magnesium silicide on the top surface of the transfer plate 111, the dust removal block 8 starts to work and absorbs the magnesium silicide dust floating in the air that may be generated during the scraping process, thereby avoiding the escape of magnesium silicide, thereby effectively reducing the potential risks caused by the floating precipitation of magnesium silicide, and effectively improving the safety and stability of the operation of the device.

[0024] like Figure 6 As shown, a material collecting block 4 is arranged below the scraper plate 3, the bottom of the material collecting block 4 is connected to the top surface of the second reaction shell 12, air supply pipes 5 and air suction pipes 6 are arranged on both sides of the material collecting block 4, a material pipe 7 is arranged at the bottom of the second reaction shell 12, and a closing plate 41 is symmetrically arranged on the inner side of the material collecting block 4. The closing plate 41 can swing relative to the inner side of the material collecting block 4. The swinging of the closing plate 41 can stop the communication between the material collecting block 4 and the second reaction shell 12. When the closing plate 41 swings, the magnesium silicide attached to the surface of the closing plate 41 can be affected by vibration and gravity changes so that it can smoothly enter the second reaction shell 12, thereby reducing the loss caused during the transmission of magnesium silicide and reducing production costs.

[0025] In this embodiment, the working scenario of a high-stability silane production reaction device is as follows: Solid dry ammonium chloride necessary for the reaction is added into the second reaction shell 12 through the material pipe 7 in advance.

[0026] A plurality of discharge pipes 24 respectively transfer the external magnesium powder and silicon powder to the top of the transfer plate 111. During the transfer process, the absorption rod 2 rotates. After the magnesium powder and silicon powder are transferred, when the top and bottom of the uniform distribution plate 25 are connected, the absorption rod 2 controls the uniform distribution plate 25 to move downward until it stops moving at the mixed raw materials close to the top surface of the transfer plate 111. Then, the top and bottom of the uniform distribution plate 25 are controlled to be isolated, and the partition block 23 moves out of the absorption through hole 21. The absorption rod 2 absorbs gas from the area on the top of the uniform distribution plate 25 through the absorption through hole 21. After the raw material dust floating on the top of the uniform distribution disk 25 is absorbed, the bottom surface of the guide disk 252 is controlled to contact the raw material on the top surface of the transfer plate 111, and then the guide disk 252 is rotated, so that the raw materials are mixed and evenly distributed in the uniform distribution groove 26. After the mixing is completed, the position of the uniform distribution disk 25 is lifted, and the top and bottom of the uniform distribution disk 25 are controlled to be connected. Then, argon gas is supplied to the first reaction shell 11 through the absorption through hole 21, and at the same time, the heating block 112 located at the bottom of the transfer plate 111 begins to heat up, and then the corresponding chemical reaction is carried out in the first reaction shell 11.

[0027] After the reaction in the first reaction shell 11 is completed, the partition block 23 covers the absorption through hole 21, controls the vertical rod 18 to move along the axis of the vertical rod 18 toward the top of the structural shell 1, and at the same time, the vertical rod 18 drives the linkage screw rod 17 to move accordingly. When the linkage screw rod 17 moves accordingly, it will drive the second slider 141 away from the first reaction shell 11 and drive the third slider 151 to move upward, so that the connecting rope 152 can drive the opening and closing plate 113 to swing upward while the translation telescopic rod 142 drives the transfer plate 111 away from the first reaction shell 11.

[0028] After the transfer plate 111 moves out of the first reaction housing 11, until the top surface of the transfer plate 111 contacts the bottom surface of the scraper plate 3, the scraper block 31 hinged to the scraper plate 3 and the dust removal block 8 on the top surface of the scraper plate 3 start working at the same time. At this time, when the scraper plate 3 and the scraper block 31 separate the magnesium silicide on the surface of the transfer plate 111 from the transfer plate 111, the floating magnesium silicide dust is absorbed by the dust removal block 8, and the translation telescopic rod 142 is continuously moved until the scraper plate 3 and the scraper block 31 push the magnesium silicide to the receiving block 4, and then the receiving block 4 transports the magnesium silicide to the second reaction housing 12. After the magnesium silicide enters the receiving block 4, the closing plate 41 swings to allow part of the magnesium silicide attached to the closing plate 41 to enter the second reaction shell 12. After all the magnesium silicide has entered, the closing plate 41 swings to close the communicating area between the receiving block 4 and the second reaction shell 12. Then, the gas supply pipe 5 inputs liquid ammonia into the second reaction shell 12, so that the ammonium chloride and magnesium silicide in the second reaction shell 12 react in the liquid ammonia to generate monosilane, magnesium chloride and ammonia gas. Then, the gas is drawn out from the suction pipe 6, and the solid and liquid are drawn out from the material pipe 7.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
