Description

Technical Field

[0001] This invention relates to the field of nanomaterial preparation technology, specifically to a synchronously belt-driven dual-spray chamber opening and closing explosion groove electro-explosion powder making device. Background Technology

[0002] The current method for preparing nanomaterials using the electro-explosion method is a novel approach that produces nanomaterials through mechanical exfoliation. A powder carrier belt is fed into a confined explosion chamber, and a storage capacitor releases a high voltage through its two electrodes. A large current is introduced into the powder material using a gap discharge mode, causing it to heat up and explode. After passing through the high temperature and high pressure in the confined explosion chamber, the explosion products are ejected from the explosion nozzle accompanied by a shock wave. The powder material is exfoliated or broken into nanomaterials under the action of high temperature, high pressure, and shock wave.

[0003] Chinese patent CN202511080607X discloses a method for preparing nanopowders using a strongly constrained, focused, electrothermal explosion device. This invention involves creating a drop-in hole on the grounding ring to allow for the feeding action of the focused tube while completely sealing the high-voltage port, leaving only the drop-in hole in the grounding port as the sole escape channel. The connection and cooperation of the convex double stud, high-voltage ring, and inner electrothermal explosion tube achieve a sealing and locking effect, thus solving the problem of secondary escape channels caused by the continuous high impact pressure during electrothermal explosion leading to sealing failure and reduced focused energy effect. However, this method has a drawback: during the explosion process, the powder to be electro-exploded needs to be sheared and dropped into the explosion tube. The shearing device's positioning is inaccurate during operation, failing to complete the shearing in time, affecting the continuity of the electro-explosion.

[0004] Chinese patent CN223055617U discloses a continuous preparation device for the confined electro-explosion method with loaded powder. This device employs multiple confined explosion chambers on a disc, solving the problem of severe ablation damage to the explosion chamber caused by continuous electro-explosion in a single chamber, a problem inherent in previous devices. However, while the device has multiple explosion chambers, all are directly formed on the same disc substrate. This integrated structure means that if any explosion chamber fails due to high-temperature ablation, it cannot be replaced individually; the entire disc-based explosion device must be replaced. This defect severely restricts the reliability and production efficiency of the confined electro-explosion method for preparing nanomaterials. Furthermore, the loaded powder channel is concentric with the explosion chamber disc and overlaps with the inner side of the confined explosion chamber. The loaded powder moves synchronously with the explosion chamber disc under the friction of the channel, leading to frequent jamming during powder replacement during the explosion process, affecting the stability and continuity of the electro-explosion operation.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a synchronously belt-driven dual-cavity opening and closing explosion groove electro-explosion pulverizing device.

[0007] A synchronous belt driven dual-cavity opening and closing explosion groove electro-explosive pulverizing device includes a moving plate and a rack. One end of the rack is provided with a drive gear, which meshes with the rack. A motor is fixedly installed on the drive gear, and the motor can drive the rack to perform reciprocating motion.

[0008] The rack meshes with the first transmission gear, which is coaxially connected to the timing belt and mounted on the moving plate. The timing belt is provided with several double-spray chamber opening and closing explosion grooves. The reciprocating motion of the rack drives the timing belt to rotate through the first transmission gear, which can drive different double-spray chamber opening and closing explosion grooves to enter the electric explosion position in sequence.

[0009] A baffle is provided on the outside of the rack, and a first stop and a second stop are provided on the moving plate. When the baffle contacts the first stop, the rack can drive the moving plate to move forward as a whole, which can send the double-spray chamber opening and closing explosion groove into the pressure plate mechanism. When the baffle contacts the second stop, the rack can drive the moving plate to move backward as a whole, which can pull the double-spray chamber opening and closing explosion groove out of the pressure plate mechanism after the electric explosion is completed. When the baffle is located between the first stop and the second stop, the rack can drive the synchronous belt to rotate to change the groove.

[0010] Preferably, the dual-cavity opening and closing explosion groove is provided with a high-voltage load electrode, a low-voltage load electrode, and an insulated explosion channel for the powder carrier to pass through. The powder carrier is electrically exploded and powdered in the discharge area between the high-voltage load electrode and the low-voltage load electrode.

[0011] The rack meshes with the second transmission gear, which is coaxially connected to the pressure plate. The powder can pass between the pressure plate and the pressure wheel. When the rack moves, it drives the pressure plate to rotate through the second transmission gear. When the pressure plate rotates, it works together with the pressure wheel to drive the powder to move synchronously. This is to ensure that the replacement of the powder and the replacement of the dual-cavity opening and closing explosion tank do not affect each other.

[0012] Preferably, the dual-cavity opening and closing explosion groove is divided into an upper explosion groove and a lower explosion groove. Guide rods are provided on both sides of the upper explosion groove and the lower explosion groove, and support springs are provided on the guide rods to ensure the directional opening and closing of the upper explosion groove and the lower explosion groove. A load high-voltage electrode is provided at one end of the upper explosion groove, and a load low-voltage electrode is provided at one end of the lower explosion groove. An insulated explosion channel is provided between the load high-voltage electrode and the load low-voltage electrode.

[0013] Preferably, both ends of the upper explosion groove are provided with sealing rubber, which can seal the insulated explosion channel. After the upper explosion groove and the lower explosion groove are closed, an explosion spray cavity can be formed on both sides of the insulated explosion channel.

[0014] Preferably, the pressure plate mechanism includes an upper inclined pressure plate, a lower inclined pressure plate, and a support rod. The inlet of the pressure plate mechanism is wider at the front and narrower at the back. After the dual-cavity opening and closing explosion groove enters the pressure plate mechanism, the upper inclined pressure plate and the lower inclined pressure plate together squeeze and close the dual-cavity opening and closing explosion groove to close and seal it for electro-explosion. A guide wheel is fixedly installed at the lower end of the support rod, and the guide wheel is used to limit the movement of the powder-carrying part.

[0015] Preferably, the pressure roller is located below the powder-carrying belt, and the pressure roller is provided with a guide plate and a clamping spring. The bottom of the guide plate is connected to the clamping spring. The bottom end of the pressure roller presses against the powder-carrying belt through the clamping spring to compress and guide the belt. The pressure disc is located above the powder-carrying belt, and the pressure disc is provided with a limiting groove. The powder-carrying belt moves within the limiting groove. The pressure disc is used to press the powder-carrying belt and feed it into the double-spray chamber opening and closing explosion groove along the direction of the insulating explosion channel.

[0016] Preferably, the height of the insulating explosion channel is adapted to the thickness of the powder-carrying material, so as to seal the powder-carrying material within the insulating explosion channel.

[0017] Preferably, a plurality of dual-spray chamber opening and closing explosion grooves are evenly distributed around the synchronous belt.

[0018] Preferably, the first transmission gear is provided with a one-way bearing, so that when the rack moves backward, the synchronous belt does not rotate counterclockwise with the first transmission gear, and when the rack moves forward, the first transmission gear drives the synchronous belt to rotate clockwise.

[0019] Compared with the prior art, the present invention provides a synchronously belt-driven dual-cavity opening and closing explosion groove electro-explosion pulverizing device, which has the following beneficial effects:

[0020] 1. This synchronous belt-driven dual-cavity opening and closing explosion groove electro-explosive pulverizing device uses a first transmission gear to drive the synchronous belt to rotate, causing the new dual-cavity opening and closing explosion groove to reach the electro-explosive position. At the same time, the rack movement drives the pressure plate to rotate through the second transmission gear, which together with the pressure plate pulley drives the synchronous replacement of the powder-carrying device. The powder-carrying device continuously and stably transports the powder-carrying device between the load high-voltage electrode and the load low-voltage electrode. This process is repeated to achieve continuous electro-explosive pulverizing of the entire device. Throughout the process, the powder-carrying device and the dual-cavity opening and closing explosion groove can be replaced synchronously, thus enabling stable and continuous electro-explosive pulverizing operations.

[0021] 2. In this synchronous belt-driven double-cavity opening and closing explosion groove electro-explosion pulverizing device, after the discharge is completed, the double-cavity opening and closing explosion groove is pulled out from the pressure plate mechanism, the support spring is reset from the compressed state and lifts the upper explosion groove, so that the double-cavity opening and closing explosion groove returns to the open state. The guide rod plays a directional guiding role in the opening and closing process to ensure the stability of opening and closing. During the electro-explosion, the powder carrying the load is heated and exploded in the discharge area between the load high voltage electrode and the load low voltage electrode. During the heating process, the sealing rubber at both ends of the insulating explosion channel can seal and lock the insulating explosion channel to prevent the high impact pressure continuously generated during the electro-explosion heating process from causing the powder to escape secondary. After the explosion, the product is constrained and accelerated secondary by the sealing rubber in the insulating explosion channel and then escapes along the explosion spray cavity, so that the explosion spray particles completely escape from the explosion spray cavity.

[0022] 3. This synchronous belt-driven dual-cavity opening and closing explosion groove electro-explosive pulverizing device, after the dual-cavity opening and closing explosion groove completes electro-explosive pulverizing, the rack reciprocating motion drives the synchronous belt to rotate, so that the next dual-cavity opening and closing explosion groove enters the electro-explosive position, realizing continuous groove changing pulverizing. The first transmission gear is equipped with a one-way bearing. When the rack moves backward, the synchronous belt does not rotate counterclockwise with the first transmission gear, ensuring that no groove turning motion occurs when the rack moves backward during the explosion, thus completing electro-explosive pulverizing. During the groove turning process, when the rack moves forward, the first transmission gear drives the synchronous belt to rotate clockwise, so that the new dual-cavity opening and closing explosion groove reaches the ready-to-enter position, which is used to realize the groove turning motion and ensure the reliability of the synchronous belt sequential groove turning.

[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] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a synchronous belt driven dual-cavity opening and closing explosion groove electro-explosion pulverizing device.

[0034] Example 1:

[0035] Please see Figure 1 - Figure 8 A synchronous belt driven double-spray chamber opening and closing explosion groove electro-explosive powder making device includes a moving plate 1 and a rack 2. One end of the rack 2 is provided with a drive gear 3, which meshes with the rack 2. A motor 4 is fixedly installed on the drive gear 3, and the motor 4 can drive the rack 2 to perform reciprocating motion.

[0036] The rack 2 meshes with the first transmission gear 5, the first transmission gear 5 is coaxially connected to the timing belt 7 and mounted on the moving plate 1, the timing belt 7 is provided with several double-spray chamber opening and closing explosion grooves 6, the reciprocating motion of the rack 2 drives the timing belt 7 to rotate through the first transmission gear 5, which can drive different double-spray chamber opening and closing explosion grooves 6 to enter the electric explosion position in sequence.

[0037] A baffle 21 is provided on the outside of the rack 2, and a first stop 101 and a second stop 102 are provided on the moving plate 1. When the baffle 21 contacts the first stop 101, the rack 2 can drive the moving plate 1 to move forward as a whole, and can send the double-spray chamber opening and closing explosion groove 6 into the pressure plate mechanism 8. When the baffle 21 contacts the second stop 102, the rack 2 can drive the moving plate 1 to move backward as a whole, and can pull the double-spray chamber opening and closing explosion groove 6 after the electric explosion is completed out of the pressure plate mechanism 8. When the baffle 21 is between the first stop 101 and the second stop 102, the rack 2 can drive the synchronous belt 7 to rotate to change the groove.

[0038] The dual-cavity opening and closing explosion tank 6 is equipped with a high-voltage load electrode 65, a low-voltage load electrode 66, and an insulated explosion channel 67 for the powder-carrying 9 to pass through. The powder-carrying 9 is electrically exploded and powdered in the discharge area between the high-voltage load electrode 65 and the low-voltage load electrode 66.

[0039] The rack 2 meshes with the second transmission gear 15, which is coaxially connected to the pressure plate 11. The powder 9 can pass between the pressure plate 11 and the pressure wheel 12. When the rack 2 moves, it drives the pressure plate 11 to rotate through the second transmission gear 15. When the pressure plate 11 rotates, it works together with the pressure wheel 12 to drive the powder 9 to move synchronously. This is to ensure that the replacement of the powder 9 and the replacement of the double-spray chamber opening and closing explosion tank 6 do not affect each other.

[0040] When entering the slot, rack 2 moves forward, baffle 21 contacts the first stop 101, driving the moving plate 1 to move forward as a whole, sending the double-spray chamber opening and closing explosion slot 6 into the pressure plate mechanism 8. When exiting the slot, rack 2 moves backward, baffle 21 contacts the second stop 102, driving the moving plate 1 to move backward as a whole, pulling the double-spray chamber opening and closing explosion slot 6, after electro-explosion, out of the pressure plate mechanism 8. When rotating the slot, baffle 21 reciprocates between the first stop 101 and the second stop 102, and the first transmission gear 5 drives the synchronous belt 7 to rotate, causing the new double-spray chamber to rotate. When the opening and closing explosion trough 6 reaches the electric explosion position, the rack 2 moves and drives the pressure plate 11 to rotate through the second transmission gear 15. Together with the pressure roller 12, it drives the carrier powder 9 to be replaced synchronously. The carrier powder 9 with powder is continuously and stably transported between the load high voltage electrode 65 and the load low voltage electrode 66. This process is repeated to realize continuous electric explosion powder making of the whole set of devices. In the whole process, the carrier powder 9 and the dual-spray chamber opening and closing explosion trough 6 can be replaced synchronously, so as to carry out electric explosion powder making operation stably and continuously.

[0041] Example 2:

[0042] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 8 The dual-cavity opening and closing explosion groove 6 is divided into an upper explosion groove 63 and a lower explosion groove 64. Guide rods 61 are provided on both sides of the upper explosion groove 63 and the lower explosion groove 64. Support springs 62 are provided on the guide rods 61 to ensure the directional opening and closing of the upper explosion groove 63 and the lower explosion groove 64. A load high voltage electrode 65 is provided at one end of the upper explosion groove 63, and a load low voltage electrode 66 is provided at one end of the lower explosion groove 64. An insulated explosion channel 67 is provided between the load high voltage electrode 65 and the load low voltage electrode 66.

[0043] The upper explosion groove 63 is provided with sealing rubber 68 at both ends. The sealing rubber 68 can seal the insulated explosion channel 67. After the upper explosion groove 63 and the lower explosion groove 64 are closed, they can form explosion spray chambers 69 on both sides of the insulated explosion channel 67.

[0044] During the slot replacement process, the dual-cavity opening and closing explosion slot 6 is in an open state. The powder-carrying material 9 enters the space between the upper explosion slot 63 and the lower explosion slot 64 along the direction of the insulating explosion channel 67. After entering the pressure plate mechanism 8, the upper explosion slot 63 and the lower explosion slot 64 are squeezed and closed to form the insulating explosion channel 67. The sealing rubber 68 set at both ends of the upper explosion slot 63 seals and constrains the energy accumulation of the insulating explosion channel 67, forming two explosion spray chambers 69 connected to the insulating explosion channel 67. After the discharge ends, the dual-cavity opening and closing explosion slot 6 is pulled out from the pressure plate mechanism 8, and the support spring 62 returns to its original state from compression and lifts the upper explosion slot 63, so that the dual-cavity opening and closing explosion slot 6 returns to its open state. In the open state, the guide rod 61 plays a directional guiding role during the opening and closing process, ensuring the stability of opening and closing. During the electric explosion, the powder 9 carrying the load is heated and explodes in the discharge area between the load high voltage electrode 65 and the load low voltage electrode 66. During the heating process, the sealing rubber 68 at both ends of the insulating explosion channel 67 can seal and lock the insulating explosion channel 67 to prevent the high impact pressure continuously generated during the electric explosion heating process from causing the powder to escape secondary. After the explosion, the products are constrained and accelerated twice in the insulating explosion channel 67 by the sealing rubber 68, and then escape along the explosion nozzle 69, which can make the explosion ejected particles completely escape from the explosion nozzle 69.

[0045] Example 3:

[0046] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 8The pressure plate mechanism 8 includes an upper inclined pressure plate 81, a lower inclined pressure plate 82, and a support rod 83. The entrance of the pressure plate mechanism 8 is wider at the front and narrower at the back. After the double-spray chamber opening and closing explosion groove 6 enters the pressure plate mechanism 8, the upper inclined pressure plate 81 and the lower inclined pressure plate 82 together squeeze and close the double-spray chamber opening and closing explosion groove 6, which is used to close and seal the double-spray chamber opening and closing explosion groove 6 for electric explosion. The lower end of the support rod 83 is fixedly installed with a guide wheel 10, which is used to limit the movement of the powder 9.

[0047] The pressure roller 12 is located below the powder-carrying belt 9. The pressure roller 12 is equipped with a guide plate 13 and a clamping spring 14. The bottom of the guide plate 13 is connected to the clamping spring 14. The bottom end of the pressure roller 12 presses against the powder-carrying belt 9 through the clamping spring 14 to press and guide the belt. The pressure disc 11 is located above the powder-carrying belt 9. The pressure disc 11 is equipped with a limiting groove. The powder-carrying belt 9 moves in the limiting groove. The pressure disc 11 is used to press the powder-carrying belt 9 and feed it into the double-spray chamber opening and closing explosion groove 6 along the direction of the insulating explosion channel 67.

[0048] The height of the insulating explosion channel 67 is adapted to the thickness of the powder 9, and is used to seal the powder 9 within the insulating explosion channel 67.

[0049] Several double-spray chamber opening and closing explosion grooves 6 are evenly distributed around the synchronous belt 7.

[0050] The first transmission gear 5 is equipped with a one-way bearing. When the rack 2 moves backward, the synchronous belt 7 does not rotate counterclockwise with the first transmission gear 5. When the rack 2 moves forward, the first transmission gear 5 drives the synchronous belt 7 to rotate clockwise.

[0051] During the entry process, the double-cavity opening and closing explosion trough 6 is fed into the pressure plate mechanism 8. The inlet structure, which is wider at the front and narrower at the back, allows the double-cavity opening and closing explosion trough 6 to gradually transition from an open state to a closed and sealed state. The upper inclined pressure plate 81 and the lower inclined pressure plate 82 together squeeze and close the double-cavity opening and closing explosion trough 6, which is used to close and seal the double-cavity opening and closing explosion trough 6 for electro-explosion. At the same time, the guide pulley 10 guides the powder-carrying belt 9 to enter the double-cavity opening and closing explosion trough 6 along the direction of the insulated explosion channel 67. The pressure pulley... Located below the powder-carrying roller 9, the pressure roller 12 is equipped with a guide plate 13 and a clamping spring 14. The pressure roller 11 is located above the powder-carrying roller 9 and is coaxially connected to the second transmission gear 15. The pressure roller 11 is provided with a limiting groove. During the rotation process, the rack 2 moves and drives the pressure roller 11 to rotate through the second transmission gear 15. Together with the pressure roller 12, it continuously conveys the powder-carrying roller 9 along the limiting groove to the space between the two electrodes. The clamping spring 14 ensures that the powder-carrying roller 9 is within the pressure roller 11 during the wire feeding process and the stationary process. The belt is pressed against the pressure roller 12. The movement and replacement of the powder-carrying 9 are synchronized with the replacement of the double-cavity opening and closing explosion groove 6 without affecting each other. After the double-cavity opening and closing explosion groove 6 is closed, the height of the insulating explosion channel 67 is adapted to the thickness of the powder-carrying 9, which is used to seal the powder-carrying 9 in the insulating explosion channel 67 to prevent lateral leakage of powder during the electric explosion. Several double-cavity opening and closing explosion grooves 6 are evenly distributed around the synchronous belt 7. When a double-cavity opening and closing explosion groove 6 completes the electric explosion powder making, the rack 2 reciprocates and drives the synchronous belt 7 to rotate so that the next double-cavity opening and closing explosion groove 6 enters the electric explosion position. At the same time, the second transmission gear 15 meshing with the rack 2 rotates, driving the pressure plate 11 connected to it to rotate. Under the joint action of the pressure roller 12, the movement and replacement of the powder-carrying 9 are carried out, and the powder-carrying 9 is continuously and stably transported between the load high-voltage electrode 65 and the load low-voltage electrode 66. This is repeated to realize the continuous electric explosion powder making of the whole device. Throughout the process, the powder carrier 9 and the dual-spray chamber opening and closing explosion trough 6 move synchronously to replace each other, resulting in stable and continuous electro-explosive powder production.
