DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1: Please refer to Figure 1-Figure 4 A silicon material drying device for high-pressure pulse crushing of silicon material comprises a drying chamber 100, a pulse crushing chamber 200 is installed on the top of the drying chamber 100, a hot air conveying pipe 300 is installed on the bottom of the drying chamber 100, a ventilation placement plate 400 is installed inside the drying chamber 100, and an air guide plate 500 driven by a servo motor is installed inside the drying chamber 100. After the silicon material that has completed the crushing operation in the high-pressure pulse crushing chamber 200 falls onto the ventilation placement plate 400 in the drying chamber 100, hot air is sent into the hot air conveying pipe 300, and the servo motor is started at the same time to drive the air guide plate 500 connected to the servo motor to rotate, so as to guide the sent hot air to various positions of the silicon material; The side of the air guide plate 500 is connected to a sprocket wheel 1 601 in a transmission manner, and a chain 602 is installed on the outer side of the sprocket wheel 1 601. A fixed seat 603 is installed on the side of the drying chamber 100. A reciprocating screw rod 604 is rotatably connected to the inside of the fixed seat 603, and a sprocket wheel 2 605 is fixedly connected to the outer side of the reciprocating screw rod 604. One end of the chain 602 away from the sprocket wheel 1 601 is installed on the outer side of the sprocket wheel 2 605. When the air guide plate 500 rotates, the sprocket wheel 1 601 connected to it can be driven to rotate synchronously, and the chain 602 installed on the outer side of the sprocket wheel 1 601 can be used to rotate the sprocket wheel 2 605 connected to the sprocket wheel 1 601 through the chain 602.

[0019] The outer side of the reciprocating screw rod 604 is connected with a sliding block 606 by threading, and the sliding block 606 is located inside the fixed seat 603 and is in a sliding connection with the fixed seat 603. When the sprocket wheel 605 rotates, the fixedly connected reciprocating screw rod 604 can be driven to rotate, because the sliding block 606 is assembled on the outer side of the reciprocating screw rod 604 by threading, and the sliding block 606 is restricted by the fixed seat 603 slidably connected thereto, so that when the reciprocating screw rod 604 rotates, the sliding block 606 reciprocates in the horizontal direction.

[0020] The side of the sliding block 606 is rotatably connected to a gear 607, the side of the drying bin 100 is equipped with a gear rod 608, the gear rod 608 meshes with the gear 607, the side of the gear 607 is fixedly connected to a rotating cylinder 609, the outer side of the rotating cylinder 609 is rotatably connected to a flip plate 610, the interior of the drying bin 100 is equipped with a swing assembly 700 that can assist in flipping the silicon material, and the side of the drying bin 100 is equipped with a limit assembly 800 that can limit the ventilation placement plate 400. When the sliding block 606 moves back and forth in the horizontal direction, it can drive the gear 607 connected to it to move synchronously. Because the gear 607 is restricted by the gear rod 608 meshing with it, the gear 607 rotates synchronously when moving in the horizontal direction, thereby driving the rotating cylinder 609 connected to the gear 607 to move in the horizontal direction and rotate synchronously. The rotating cylinder 609 drives the flip plate 610 connected to it to flip the silicon material on the ventilation placement plate 400 in turn, thereby increasing the contact area between the silicon material and the hot air, and improving the drying efficiency of the device.

[0021] When in use, after the silicon material that has completed the crushing operation in the high-pressure pulse crushing chamber 200 falls onto the ventilation placement plate 400 in the drying chamber 100, hot air is sent into the hot air conveying pipe 300, and the servo motor is started at the same time to drive the air guide plate 500 connected to it to rotate, so as to guide the sent hot air to various positions of the silicon material; the rotating air guide plate 500 synchronously drives the sprocket wheel 1 601 connected to it to rotate, and cooperates with the chain 602 assembled on the outside of the sprocket wheel 1 601, so that the sprocket wheel 2 605 connected to the sprocket wheel 1 601 through the chain 602 rotates, and the sprocket wheel 2 605 drives the fixedly connected reciprocating screw rod 604 to rotate, because the sliding block 606 is assembled on the reciprocating screw rod 604 through a thread. The sliding block 606 is on the outside of the rotating plate 400, and is restricted by the fixed seat 603 slidably connected thereto, so that when the reciprocating screw rod 604 rotates, the sliding block 606 reciprocates in the horizontal direction, and the sliding block 606 drives the gear 607 rotatably connected thereto to move synchronously. Because the gear 607 is restricted by the gear rod 608 meshing therewith, the gear 607 rotates synchronously when moving in the horizontal direction, thereby driving the rotating cylinder 609 connected to the gear 607 to move in the horizontal direction and rotate synchronously at the same time, so that the rotating cylinder 609 drives the flip plate 610 rotatably connected thereto to flip the silicon material on the ventilation placement plate 400 in turn, thereby increasing the contact area between the silicon material and the hot air.

[0022] Example 2: Please refer to Figure 1-Figure 6 On the basis of the first embodiment, the swing assembly 700 includes a mounting seat 701 fixed inside the rotating cylinder 609, a hydraulic device 702 is installed inside the mounting seat 701, a disc 703 is connected to the side of the reciprocating screw 604, and an extrusion block 705 is rotatably connected to the outer side of the disc 703 through a torsion spring block 704. Four extrusion blocks 705 are arranged, and the four extrusion blocks 705 are distributed in a circumferential array on the disc 703. Figure 5 From a middle perspective, when the reciprocating screw rod 604 is in a clockwise rotation state, it can drive the disc 703 connected to it to rotate clockwise, so that the disc 703 drives the extrusion block 705 connected to it through the torsion spring block 704 to rotate clockwise synchronously.

[0023] The side of the hydraulic device 702 is slidably connected with a force rod 706, which is located at the side of the extrusion block 705 and contacts the extrusion block 705. The side of the force rod 706 is equipped with a spring 707. When the extrusion block 705 rotates to the force rod 706, the force rod 706 can be squeezed. Since the extrusion block 705 is restricted by the disc 703 at this time, the extrusion block 705 squeezes the force rod 706 and slides into the hydraulic device 702. When the extrusion block 705 continues to rotate and moves away from the force rod 706, the force rod 706 can be reset under the action of the spring 707, so that the force rod 706 can reciprocate. The end of the hydraulic device 702 away from the force rod 706 is slidably connected with an arc rod 708, and the arc rod 708 is fixedly connected to the flip plate 610. When the force-bearing rod 706 moves back and forth, in cooperation with the hydraulic device 702 slidably connected to the force-bearing rod 706, the arc rod 708 slidably connected to the hydraulic device 702 can be driven to move back and forth, so that the arc rod 708 drives the flip plate 610 fixedly connected to it to swing back and forth to a certain extent, further increasing the contact area between the silicon material and the hot air, thereby further improving the drying efficiency of the device.

[0024] For situations where the flip plate 610 does not need to be swung, such as for some powdered silicon materials, the reciprocating screw 604 is adjusted to a counterclockwise rotation state, so that the disc 703 drives the extrusion block 705, which is rotatably connected to it through the torsion spring block 704, to rotate counterclockwise. The torsion force of the torsion spring inside the torsion spring block 704 is less than the elastic force of the spring 1 707, so that when the extrusion block 705 rotates to the force-bearing rod 706, the extrusion block 705 is squeezed by the force-bearing rod 706, resulting in a clockwise rotation of a certain angle. At this time, the force-bearing rod 706 does not move, so that the flip plate 610 does not swing back and forth, so that the device can be used for different situations, thereby improving the usability of the device.

[0025] When used, based on the first embodiment, Figure 5From a middle perspective, when the reciprocating screw rod 604 is in a clockwise rotation state, it can drive the disc 703 connected to it to rotate clockwise, so that the disc 703 drives the extrusion block 705 connected to it through the torsion spring block 704 to rotate clockwise synchronously. When the extrusion block 705 rotates to the force-bearing rod 706, the force-bearing rod 706 can be squeezed. Because the extrusion block 705 is restricted by the disc 703 at this time, the extrusion block 705 squeezes the force-bearing rod 706 and slides into the hydraulic device 702. When the extrusion block 705 continues to rotate and moves away from the force-bearing rod 706, the force-bearing rod 706 can be reset under the action of the spring 707. In this way, the force-bearing rod 706 can move back and forth, cooperating with the hydraulic device 702 slidably connected to the force-bearing rod 706. , which can drive the arc rod 708 slidably connected to the hydraulic device 702 to move back and forth, so that the arc rod 708 drives the flip plate 610 fixedly connected thereto to swing back and forth to a certain extent; when there is no need to use the flip plate 610 to swing, the reciprocating screw rod 604 is adjusted to a counterclockwise rotation state, so that the disc 703 drives the extrusion block 705 rotatably connected to it through the torsion spring block 704 to rotate counterclockwise, and the torsion force of the torsion spring inside the torsion spring block 704 is less than the elastic force of the spring 1 707, so that when the extrusion block 705 rotates to the force-bearing rod 706, the extrusion block 705 is squeezed by the force-bearing rod 706, and produces a clockwise rotation of a certain angle. At this time, the force-bearing rod 706 does not move, so that the flip plate 610 does not swing back and forth.

[0026] Example 3: Please refer to Figure 1-Figure 8 On the basis of the first and second embodiments, the limit assembly 800 includes a hydraulic chamber 801, one end of which is slidably connected to a sensing rod 802, which is located at the side of the sliding block 606. When the limit assembly 800 is enabled, the sensing rod 802 contacts the sliding block 606. When the sliding block 606 drives the flip plate 610 to move to the side close to the ventilation placement plate 400 that can be withdrawn, the sliding block 606 can squeeze the sensing rod 802 and drive the sensing rod 802 to move to the side, and cooperate with the hydraulic chamber 801 slidably connected to the sensing rod 802, so that the pressure in the hydraulic chamber 801 increases.

[0027] The other end of the hydraulic chamber 801 is slidably connected to a limit rod 803, a spring 2 804 is mounted on the side of the sensing rod 802, and a limit slot 805 is provided on the side of the drying chamber 100 and the ventilation placement plate 400. When the pressure in the hydraulic chamber 801 increases, the limit rod 803 slidably connected to the hydraulic chamber 801 is driven to move, and the limit rod 803 then passes through the limit slot 805 on the drying chamber 100 and is inserted into the limit slot 805 on the side of the ventilation placement plate 400, preventing the ventilation placement plate 400 from being shaken out of the slot on the drying chamber 100 when the flip plate 610 moves to that side, thereby improving the stability of the device when in use. When the sliding block 606 is away from the side where the ventilation placement plate 400 can be withdrawn, the sensing rod 802 loses its limit and can be reset under the action of the spring 2 804, and similarly, the limit rod 803 is reset to facilitate the next use of the limit assembly 800.

[0028] When in use, on the basis of Example 1 and Example 2, when the sliding block 606 drives the flip plate 610 to move to the side close to the ventilation placement plate 400 that can be pulled out, the sliding block 606 can squeeze the sensing rod 802 and drive the sensing rod 802 to move sideways, and cooperate with the hydraulic bin 801 that is slidably connected to the sensing rod 802, so that the pressure in the hydraulic bin 801 increases, driving the limit rod 803 that is slidably connected to the hydraulic bin 801 to move, and the limit rod 803 then passes through the limit groove 805 on the drying bin 100 and is inserted into the limit groove 805 on the side of the ventilation placement plate 400; when the sliding block 606 is away from the side where the ventilation placement plate 400 can be pulled out, the sensing rod 802 loses its restriction and can be reset under the action of the spring 2 804, and similarly, the limit rod 803 is reset.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
