Description

[0002] The Komatsu method for synthesizing silane and disilane requires the preparation of silicon-magnesium alloy first. The preparation of silicon-magnesium alloy is to put the uniformly mixed silicon powder and magnesium powder into a fixed bed vacuum furnace tank, and heat and react in a well-type heating furnace to produce silicon-magnesium alloy. After the reaction, the alloy in the vacuum furnace tank is in a whole block. The whole block of material in the furnace tank is manually broken into small pieces before taking it out, which is a large workload and low efficiency.

[0003] At present, mechanical crushing is also adopted in the market, where a deformable cutting blade is inserted into the vacuum furnace and then automatically unfolds to crush the alloy. However, the solid blocks generated by this crushing accumulate more and more, which not only squeezes the cutting blade and causes the blade to wear, but also causes some solid blocks to be over-crushed multiple times, resulting in specifications that do not meet the standards.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] See also Figure 1-3 , an automatic crushing device for silicon-magnesium alloy in a fixed bed furnace, comprising a vacuum furnace body 1, a crushing mechanism 2 is arranged inside the vacuum furnace body 1, the crushing mechanism 2 comprises a driving shaft 21, a foldable cutting blade 22 is arranged at the bottom of the driving shaft 21, and a differential is arranged at the connection between the driving shaft 21 and the cutting blade 22, characterized in that: an operating frame 3 is arranged outside the vacuum furnace body 1, a reaction furnace 11 is fixedly connected to the inner bottom of the vacuum furnace body 1, a discharge hole 12 is opened at the outer end of the reaction furnace 11 near the top, a discharge hopper 13 near the discharge hole 12 is fixedly connected to the inner wall of the reaction furnace 11, and a driving component 5 is arranged inside the reaction furnace 11;

[0040] The driving component 5 includes a propeller 41 that rotates with the driving shaft 21. The driving component 5 is used to move the propeller 41 up and down, so that the propeller 41 lifts the crushed materials to the discharge hopper 13 during the rotation. The driving shaft 21 is a square structure, and a sliding sleeve 42 is slidably connected to the outside of the driving shaft 21. The inner wall of the sliding sleeve 42 is adapted to the outer wall of the driving shaft 21. A feed port is opened at the top of the reaction furnace 11.

[0041] See also Figure 1 A stepper motor 23 is arranged at the top of the driving shaft 21, and the end of the stepper motor 23 is movably connected to the top of the driving shaft 21. A support platform is fixedly connected to the top of the stepper motor 23. A pair of hydraulic cylinders are arranged between the support platform and the top of the operating frame 3. The hydraulic cylinders are responsible for slowly transporting the cutting blade 22 to the inner bottom of the reaction furnace 11. The cutting blade 22 can be folded automatically by electric control, and can pass through the inside of the sliding sleeve 42 after folding.

[0042] The internal structure of the reaction furnace 11 of this device is made of high temperature resistant materials.

[0043] During actual operation, the vacuum furnace body 1 is placed inside the operating frame 3, and the clamping cylinder is turned on. The cylinder starts to move with the buffer pad at the end until it touches the vacuum furnace body 1 to fix it. Then the cutting blade 22 is placed inside the reactor 11, and the stepper motor 23 is turned on. It not only drives the cutting blade 22 to rotate quickly through the differential, but also drives the propeller 41 to rotate continuously, thereby realizing the transportation of the crushed solid blocks to the propeller 41. The subsequent solid blocks are put into the discharge hopper 13, and finally slide to the outside of the reactor 11 for collection, so that the crushed solid blocks will not continue to press the crushing blade, nor will they be crushed by it for the second time, resulting in excessive crushing.

[0044] See also Figure 4-5 The reciprocating lifting component 4 includes a multi-stage telescopic cylinder 43, a plurality of arc-shaped pieces 44 are fixedly connected to the top of the multi-stage telescopic cylinder 43, a fixed plate 45 is fixedly connected to the inner wall of the reaction furnace 11, and the arc-shaped piece 44 is rotatably connected to the bottom of the fixed plate 45, and a cover plate 46 is fixedly connected to the inner wall of the multi-stage telescopic cylinder 43. The cover plate 46 is movably connected to the outside of the sliding sleeve 42 through a bearing, and a discharge hole 47 is opened on the cover plate 46. The first gear bar 48 and the second gear bar 49 are slidably connected to the cover plate 46. A driving component 5 is also provided on the vacuum furnace body 1, and the driving component 5 is used to alternately move the first gear bar 48 and the second gear bar 49 up and down.

[0045] The multi-stage telescopic cylinder 43 in this embodiment is specifically a three-stage telescopic structure, including a bottom cylinder 431, a middle cylinder 432 and an inner cylinder 433. The top of the inner cylinder 433 is connected to the fixed plate 45 through an arc-shaped piece 44, so the end of the inner cylinder 433 is fixed. Therefore, when the bottom cylinder 431 moves up and down, the transportation of solid blocks can be realized.

[0046] The first gear bar 48 and the second gear bar 49 move up and down intermittently, respectively, so that the propeller 41, the cover plate 46 and the bottom cylinder 431 move up and down. As the propeller 41 rotates, the solid blocks are lifted and climb on the propeller 41. When the inner cylinder 433 rises to the highest point, due to the action of centrifugal force, the solid blocks close to the discharge hole 47 will be thrown out, and the solid blocks fall on the discharge hopper 13 and finally slide to the outside of the reactor 11.

[0047] See also Figure 6-8 The driving component 5 includes a reduction motor 51, the output end of the reduction motor 51 is fixedly sleeved with a driving shaft 52, the shaft wall of the driving shaft 52 is fixedly sleeved with a driving gear 53, and the driving gear 53 is meshed with the first gear bar 48 or the second gear bar 49 when working. The outer ends of the first gear bar 48 and the second gear bar 49 are slidably connected with the first telescopic member 54 and the second telescopic member 55, respectively. The side ends of the first gear bar 48 and the second gear bar 49 are provided with guide grooves, and the first telescopic member 54 and the second telescopic member 55 slide in the guide grooves of the first gear bar 48 and the second gear bar 49 through sliders, respectively, and the outer end of the first telescopic member 54 is fixedly connected with a first air pipe 56, and the bottom of the first air pipe 56 is abutted with a one-way channel component 57, and the number of the one-way channel components 57 is two. A one-way channel component 57 is responsible for one-way gas transportation. The bottom of the one-way channel component 57 is abutted against a second air pipe 58. The end of the second air pipe 58 is fixedly connected to an air storage box 59. The inner wall of the air storage box 59 is fixedly connected to an air bag 510. The top of the air bag 510 is fixedly connected to a piston member 511 responsible for reciprocating pressing of the air bag 510. The shaft wall of the active shaft 52 is also fixedly sleeved with a pressure rod 512. A third air pipe 513 is fixedly connected between the outer end of the air storage box 59 and the outer end of the second telescopic member 55. Another one-way channel component 57 divides the third air pipe 513 into two and connects the inside thereof. The latch teeth on the first gear bar 48 and the second gear bar 49 adopt an elastic telescopic structure for left and right telescopic. When it is not well meshed with the driving gear 53, it can be telescoped first and then meshed.

[0048] The first telescopic member 54 and the second telescopic member 55 are both hollow cylinders and movable cylinders that move inside the hollow cylinders. After the gas enters the hollow cylinders, the movable cylinders are squeezed by the gas pressure, so that the movable cylinders can be freely extended and retracted.

[0049] Taking the meshing of the second gear bar 49 and the driving gear 53 as an example, the reduction motor 51 is turned on, and the second gear bar 49 will move the cover plate 46 and the bottom cylinder 431 downward by rotating the driving gear 53. During the movement, the fixed block 76 is continuously transported upward by the rotation of the propeller 41, and the solid block stays on the propeller 41. At the same time, the pressure rod 512 is also continuously rotating slowly. Each time it rotates, the airbag 510 will be pressed by the piston member 511, so that the internal gas of the second telescopic member 55 is continuously transported to the first telescopic member 54, so that the second telescopic member 55 is continuously shortened and the first telescopic member 54 is continuously extended. After a period of time, the second gear bar 49 is separated from the driving gear 53, and at this time the first gear bar 48 is meshed with the driving gear 53, and the first gear bar 48 moves the cover plate 46 and the propeller 41 upward. When it rises to the highest point, the solid block near the discharge hole 47 will be thrown out under the action of centrifugal force, and the solid block falls on the discharge hopper 13 and finally slides to the outside of the reactor 11.

[0050] When initially set, the gas can only be transported from the inside of the second telescopic member 55 to the inside of the first telescopic member 54 .

[0051] Preferably, the cover plate 46 may be arched or semicircular, with the curved surface slightly curved downward. If a very small amount of solid blocks fall on the cover plate 46 , when the cover plate 46 rises to the highest point, the solid blocks may automatically fall onto the discharge hopper 13 .

[0052] The one-way channel assembly 57 includes a movable disk 571 , on which a one-way air hole 572 is formed, and inside of the one-way air hole 572 a one-way valve 573 is fixedly connected.

[0053] See also Fig. 9 The side end of the movable disk 571 is fixedly connected with an intermittent rotating component 6, and the intermittent rotating component 6 is responsible for intermittently rotating the movable disk 571. The intermittent rotating component 6 includes a first driven shaft 61 and a pair of second driven shafts 62, one end of the second driven shaft 62 is fixedly connected with an intermittent rotating disk 63, and the other end of the second driven shaft 62 is fixedly connected to the movable disk 571. The outer end of the first driven shaft 61 is fixedly sleeved with a brake disk 64 and a driven gear 65, and an arc groove is provided at the outer end of the brake disk 64. The outer end of the driving shaft 52 is also fixedly sleeved with a driving gear 66, and the driving gear 66 is meshed with the driven gear 65. The side end of the brake disk 64 is fixedly connected with a toggle disk 67, and the side end of the toggle disk 67 is fixedly connected with a toggle rod 68. During the rotation of the toggle rod 68, the intermittent rotating disk 63 can be rotated to a set angle. In this embodiment, the pressure rod 512 is fixedly connected to the outer wall of the first driven shaft 61 to slow down the rotation speed of the pressure rod 512 (the figure also takes the fixing on the first driven shaft 61 as an example).

[0054] Furthermore, the outer end of the air storage box 59 is fixedly connected to an air supply pipe 79 (see Fig.10), a pressure limiting valve is provided inside the air supply pipe 79, and when the air bag 510 exceeds the set air pressure, the pressure limiting valve opens.

[0055] The intermittent turntable 63 includes an arc portion 631 and a latch portion 632. The arc portion 631 and the latch portion 632 are evenly spaced. The number can be set according to actual conditions, generally 2-4. The lever 68 and the latch portion 632 are adapted to each other.

[0056] The driving shaft 52 is sleeved with a driving gear 66, which drives the driven gear 65 to rotate slowly, with a gear ratio of 1:5-10. The driven gear 65 drives the brake disc 64 and the toggle disc 67 to rotate. When the toggle lever 68 rotates to the inner wall of the latch portion 632, it drives the intermittent turntable 63 to rotate a specific angle, which is 90 degrees in this embodiment. At this time, the movable disc 571 rotates 90 degrees, and then the pressure rod 512 presses the piston member 511, which is in the shape of an "I". As the air pressure in the airbag 510 increases, the pressure limiting valve is opened, and the gas is released from the airbag 510. After the air supply pipe 79 comes out, after a period of time, the lever 68 drives the intermittent turntable 63 to rotate 90 degrees. At this time, the pair of intermittent turntables 63 will rotate 180 degrees. At this time, the position of the one-way valve 573 changes, and the gas can only enter the second telescopic member 55 from the inside of the first telescopic member 54. The pressure rod 512 continues to rotate, which will cause the first telescopic member 54 to continue to shorten and the second telescopic member 55 to continue to extend, and finally the first gear bar 48 is separated from the driving gear 53, and the second gear bar 49 is engaged with the driving gear 53, and continues to reciprocate up and down.

[0057] See also Figure 10-13 In an embodiment further provided by the present invention, a flow limiting component 7 is arranged inside the air storage box 59, and the flow limiting component 7 includes a baffle 71, and an elastic member 72 is fixedly connected to the bottom of the baffle 71 and the inner bottom of the air storage box 59, and evenly distributed baffle bars 73 are fixedly connected to the baffle 71. A movable frame 74 is slidably connected to the inner wall of the air storage box 59, and a limiting plate 75 is fixedly connected to the side end of the movable frame 74. A fixed block 76 is fixedly connected to the top of the air storage box 59, and a reset member 77 is fixedly connected between the fixed block 76 and the movable frame 74. A push rod 78 is fixedly connected to the outer end of the movable disk 571, and the push rod 78 will toggle the movable frame 74 during rotation. The reset member 77 and the elastic member 72 are both compression springs. Initially, the limiting plate 75 clamps the lowest baffle bar 73 to prevent the baffle 71 from moving downward.

[0058] Specifically, a hose is also provided in the air storage box 59, and the hose is connected to the airbag 510. Initially, the baffle 71 is located above the hose. When the movable disk 571 rotates to a specific angle, it will also rotate with the push rod 78, and the movable frame 74 is moved by the push rod 78 to temporarily separate the limit plate 75 from the baffle bar 73, so that the baffle 71 descends. Under the action of the reset member 77, the movable frame 74 is quickly reset to jam the baffle bar 73 of the second layer. At this time, the baffle 71 moves down one grid to reduce the air intake, so that the time required for the next extension of the first telescopic member 54 is lengthened (the value can be adjusted to one time as needed), that is, the second gear plate descends for a longer time, and the propeller 41 descends a longer distance, so that more solid blocks can be transported. When the solid blocks of the first layer are transported, it will move to the second layer next time to transport the fixed blocks 76 of the second layer, and finally the solid blocks are transported layer by layer to the outside of the reactor 11.

[0059] See also Fig.14 In an embodiment further provided by the present invention, a screening component 8 is also provided inside the vacuum furnace body 1, and the screening component 8 includes a screening plate 81, and a telescopic rod 82 is fixedly connected between the screening plate 81 and the fixed plate 45. When the cover plate 46 rises to the highest point, it is located above the screening plate 81.

[0060] A plurality of push rods 83 are fixedly connected to the top of the screening plate 81 , a reciprocating plate 84 is fixedly connected to the top of the push rod 83 , an eccentric wheel 85 is fixedly sleeved on the outer end of the driving shaft 52 , and the outer end of the eccentric wheel 85 contacts the reciprocating plate 84 .

[0061] By setting the screening plate 81, when the solid blocks are centrifugally thrown above the propeller 41, the screening plate 81 continues to rotate, and the solid blocks that meet the specifications are screened out and dropped to the outside of the reactor 11 through the discharge hopper 13, while the solid blocks that do not meet the specifications are squeezed and crushed for a second time by the rising screening plate 81 and the fixed plate 45, so that all the solid blocks are screened and reach the qualified specifications.

[0062] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
