[0016] A method for preparing a device for preparing nano barium sulfate powder based on an electric explosion method comprises the following steps:

[0017] S1. Connect the device storing barium sulfate powder to the input pipe. After the connection is completed, start the material taking component. The reduction motor drives the fan blades in the fan through the belt transmission component. When the fan blades rotate, the barium sulfate powder will be drawn into the electric explosion chamber;

[0018] S2. After the barium sulfate powder is sucked into the electric explosion chamber by the fan, it will move along the route of the spiral guide convex strips, continue to move upward in a spiral route, and finally enter the discharge pipe, and then move to the inside of the air inlet pipe;

[0019] S3, remotely turning on the switch on the circuit board, so that the high-voltage package energizes the coil, generating a high-frequency electromagnetic pulse irradiation downward. Under the action of the pulse energy, mechanical stress is generated inside the barium sulfate powder, and the surface of the barium sulfate powder is also bombarded by the pulse, and finally the barium sulfate powder is deformed and broken into nano barium sulfate powder;

[0020] S4. Under the action of electromagnetic pulse bombardment, the volume of barium sulfate powder becomes smaller and the mass becomes lighter, and the original dynamic balance is broken. At this time, the centrifugal force generated by the vortex on the barium sulfate powder can suck the processed nano barium sulfate powder out of the raw material and throw it into the vortex to be carried away by the air, while the unbroken barium sulfate powder will continue to stay in the center of the vortex under the interaction of gravity, suction, electromagnetic pulse impact force and centrifugal force until it is bombarded into nano barium sulfate powder and then sucked away by the airflow;

[0021] S5. After being processed by the electric explosion component, the air is discharged from the air outlet pipe carrying the nano-barium sulfate powder. The nano-barium sulfate powder in the air will be sent to the collection room for centralized filtration, thus completing the processing of the nano-barium sulfate powder.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, nano-barium sulfate powder is prepared by an electric explosion method. The electric explosion method uses electromagnetic pulses to process barium sulfate powder. Compared with the mechanical structure of a ball mill, the electric explosion can release a large amount of energy in a short time, promote the rapid reaction of barium sulfate powder and form nano-barium sulfate powder, and improve the crystallinity and purity of the product. Compared with the repeated mechanical grinding of a ball mill, the electric explosion method can complete the preparation in a short time, improve production efficiency, and use electric energy to react, and also avoid the influence of mechanical wear on equipment and materials during ball milling, reducing the cost of equipment repair and maintenance. In addition, the electric explosion method does not require the use of organic solvents or other chemical reagents, which not only reduces production costs, but also reduces pollution to the environment.

[0024] 2. In the present invention, the material taking component provides a power source for the movement of the barium sulfate powder. By generating an air flow vortex in the electric explosion chamber, the large volume and mass of the barium sulfate powder are concentrated at the center of the electric explosion chamber, ensuring that the emitted electromagnetic pulse can accurately bombard the barium sulfate powder, further improving the processing efficiency and accuracy. The centrifugal force generated by the vortex will separate the barium sulfate powder that has been broken into nanometer level from the raw material, leaving only the unbroken barium sulfate powder, thereby completely avoiding the problem of repeated processing of the barium sulfate powder, and also saving the time of taking out the barium sulfate powder from the electric explosion chamber.

[0025] 3. In the present invention, spiral guide convex strips are arranged on the inner wall of the electric blasting chamber to guide the flow direction of the air, so as to ensure that the flow direction of the vortex is spirally ascending during the flow of air. A partition component for preliminary filtering of barium sulfate powder is also installed on the outer wall of the input pipe. The partition component performs preliminary filtering of the barium sulfate powder entering the electric blasting chamber through a filter screen to prevent some impurities from entering the electric blasting chamber and affecting the normal electric blasting processing, thereby ensuring the safety of the entire device during use.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of 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.

[0036] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown: a device for preparing nano-barium sulfate powder based on electric explosion method, comprising a support frame 1, an electric explosion component 2 is fixedly installed on the top of the support frame 1, one end of the electric explosion component 2 is fixedly connected to a material taking component 4, and one end of the material taking component 4 is fixedly connected to a collecting chamber 7;

[0037] The electric explosion assembly 2 includes an electric explosion chamber 21, a battery 26, a high-voltage package 27, a circuit board 28, a guide tube 29 and a coil 210. The battery 26 is inserted into the high-voltage package 27, and the output end of the battery 26 is movably connected to the power line of the high-voltage package 27. The positive and negative electrodes of the high-voltage package 27 are fixedly connected with a wire 213. The positive electrode of the high-voltage package 27 is fixedly connected to the positive electrode of the circuit board 28 through the wire 213. The wire 213 is fixedly installed on the circuit board 28. The coil 210 is wound on the outer wall of the guide tube 29. One end of the coil 210 is fixedly connected to the inside of the circuit board 28. A discharge gap is left between one end of the coil 210 and one of the wires 213. The other end of the coil 210 is fixedly connected to another wire 213 to avoid burning the high-voltage package 27. One end of the guide tube 29 is fixedly connected to the inside of the circuit board 28. One end of the guide tube 29 is fixedly connected to the inside of the electric explosion chamber 21. The guide tube 29 is located on the axis of the electric explosion chamber 21. The electric explosion chamber 21 is fixedly installed inside the support frame 1.

[0038] In this embodiment, the electric explosion component 2 is installed in the support frame 1, and the material taking component 4 connects the electric explosion component 2 and the collecting chamber 7. During processing, the barium sulfate powder is sucked into the electric explosion chamber 21 by the material taking component 4. In this process, the centrifugal force of the vortex on the barium sulfate powder and the suction force of the vortex on the barium sulfate powder and the gravity of the barium sulfate powder are in a state of dynamic equilibrium. The airflow first enters the conical cavity at the bottom of the electric explosion chamber 21, and then enters a cylindrical cavity. The whole process is affected by the shape of the electric explosion chamber 21, which will cause the airflow to start rotating, thereby forming a vortex-like flow state, and a spiral guide convex strip 212 is provided on the inner wall of the electric explosion chamber 21 to limit the direction of the air. At the same time, the discharge pipe 23 is tangent to the electric explosion chamber 21, so that the direction of the airflow in the electric explosion chamber 21 is generally in a spiral rising state along the inner wall of the electric explosion chamber 21, thereby generating a vortex. The center of the vortex is due to the air Aggregation will cause the pressure at the center to decrease, thereby generating suction for the barium sulfate powder. In addition, the barium sulfate powder itself has a certain weight. The sum of the two will reach a dynamic balance with the centrifugal force exerted by the vortex on the barium sulfate powder. Then the switch on the circuit board 28 is turned on by remote control. The voltage of the battery 26 is amplified by the high-voltage package 27 and then transmitted to the coil 210. At the same time, under the action of the guide tube 29, a downward high-frequency electromagnetic pulse irradiation is generated. The pulse energy directly bombards the barium sulfate powder, causing cracks on the surface of the barium sulfate powder, and also generates mechanical stress inside the barium sulfate powder, causing the barium sulfate powder to break into nano barium sulfate powder. The nano barium sulfate powder changes in volume and mass, which breaks the original dynamic balance and is eventually sucked into the airflow, while the unbroken barium sulfate powder particles continue to stay in the center of the vortex until they are bombarded into nano barium sulfate powder.

[0039] The positive and negative electrodes of the high-voltage package 27 are connected to the coil 210 through the wire 213. The wire 213 and the coil 210 are fixed on the circuit board 28. One wire 213 is directly connected to one end of the coil 210, and a discharge gap is left between the other wire 213 and the other end of the coil 210 to avoid burning the high-voltage package 27.

[0040] The guide tube 29 is directed vertically downward and is located on the axis of the electric explosion chamber 21 as a whole. It is used to determine the direction of the electromagnetic pulse to prevent the electromagnetic pulse from spreading around the device and affecting the normal use of other devices. A battery 26 is provided in the high-voltage package 27 to provide power for the electric explosion assembly 2.

[0041] When the high-voltage package 27 amplifies the voltage and transmits the current, the energy is released in the form of electromagnetic waves. In this process, the rapid change of the current will cause the electric field and the magnetic field to change rapidly, and the changing magnetic field will induce current in the conductor, thereby generating electromagnetic pulses.

[0042] Embodiment 2: According to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a protective shell 24 is fixedly installed on the top of the electric explosion chamber 21, a support rod 211 is fixedly installed on the inner wall of the protective shell 24, a guide tube 29 is located inside the protective shell 24, and the support rod 211 is made of insulating material.

[0043] In this embodiment, the protective shell 24 is used to protect the coil 210 and the circuit board 28, and is used to prevent the coil 210 and the circuit board 28 from contacting the outside, thereby improving the overall safety factor. At the same time, a top support rod 211 is provided inside the protective shell 24 to assist in improving the structural stability of the coil 210 and the guide tube 29, thereby preventing the guide tube 29 from loosening. A positioning platform 25 is provided on the top of the protective shell 24 to determine the position of the high-voltage package 27, thereby maintaining the overall stability.

The edge of the installation connecting plate 3 is fixedly connected to the outer wall of the electric explosion chamber 21. The partition assembly 5 includes a positioning block 51, which is fixedly installed on the outer wall of the input pipe 22. A first partition plate 52 and a second partition plate 53 are provided on one side of the positioning block 51. Filters with different apertures are fixedly installed inside the first partition plate 52 and the second partition plate 53. Extension rods 54 are fixedly installed at the edges of the first partition plate 52 and the second partition plate 53. One end of the extension rod 54 is rotatably connected to the inside of the positioning block 51.

[0046] In this embodiment, the fan blades in the fan 41 are connected to the belt drive assembly 45. When in operation, the reduction motor drives the fan blades through the belt drive assembly 45 to stir the air to flow, thereby achieving the purpose of drawing the barium sulfate powder into the electric explosion chamber 21. In addition, this method can also suck out the nano barium sulfate powder from the raw material, thereby improving the overall processing efficiency. The air inlet pipe 43 of the fan 41 is connected to the discharge pipe 23 of the electric explosion chamber 21, and a connection frame 44 is provided at the connection to improve the connection stability between the air inlet pipe 43 and the discharge pipe 23 to avoid the occurrence of pipeline misalignment.

[0047] The side of the support frame 1 is provided with an installation connecting plate 3 for installing the fan 41 and the reinforcement ring 6. The reinforcement ring 6 is mainly used to fix the air outlet pipe 42 to ensure that the air outlet pipe 42 is stably connected with the collection chamber 7. The edge of the installation connecting plate 3 is also connected with the electric explosion chamber 21, which can further improve the structural stability of the electric explosion chamber 21.

[0048] The positioning block 51 in the partition assembly 5 is fixedly installed on the outer wall of the input pipe 22. When in use, the partition assembly 5 mainly plays the role of preliminary filtering of barium sulfate powder. The first partition plate 52 and the second partition plate 53 are fixedly installed with filter screens of different calibers, which have two partitioning effects. One side of the first partition plate 52 and one side of the second partition plate 53 are covered with a cover plate, which is used to protect the filter screen. The first partition plate 52 and the second partition plate 53 are connected to the positioning block 51 through an extension rod 54. Different partition plates can be switched for use before use.

[0049] The use method and working principle of the device are as follows: first, the device storing barium sulfate powder is connected to the input pipe 22, and after the connection is completed, the material taking component 4 is started, and the reduction motor drives the fan blades in the fan 41 through the belt transmission component 45. When the fan blades rotate, the barium sulfate powder is sucked into the electric explosion chamber 21. After being processed by the electric explosion component 2, the air is discharged from the air outlet 42 carrying the nano barium sulfate powder, and the nano barium sulfate powder in the air is sent to the collection chamber 7 for centralized filtration, thereby completing the processing of the nano barium sulfate powder;

[0050] When the barium sulfate powder is drawn into the electric explosion chamber 21 by the fan 41, the discharge pipe 23 connected to the air inlet pipe 43 is located on the side of the electric explosion chamber 21, and a spiral guide convex strip 212 is provided on the inner wall of the electric explosion chamber 21 to limit the direction of the air. Therefore, the direction of the airflow in the electric explosion chamber 21 is generally in a spiral upward state along the inner wall of the electric explosion chamber 21, thereby generating a vortex. Due to the gathering of air at the center of the vortex, the pressure at the center is reduced, thereby generating suction for the barium sulfate powder. In addition, the barium sulfate powder itself has a certain weight, and the sum of the two will reach a dynamic balance with the centrifugal force exerted by the vortex on the barium sulfate powder, so that the barium sulfate powder gathers in the central area of ​​the electric explosion chamber 21;

[0051] Then, the switch on the circuit board 28 is turned on by remote control, so that the high-voltage package 27 energizes the coil 210, and generates a high-frequency electromagnetic pulse irradiation downward. Under the action of the pulse energy, mechanical stress is generated inside the barium sulfate powder, and the surface of the barium sulfate powder is also bombarded by the pulse, and finally the barium sulfate powder is deformed and broken into nano barium sulfate powder;

[0052] Under the action of electromagnetic pulse bombardment, the volume of barium sulfate powder becomes smaller and the mass becomes lighter, and the original dynamic balance is broken. At this time, the gravity of the barium sulfate powder with lighter mass will become smaller, making the original gravity of the barium sulfate powder plus the suction of the vortex on the barium sulfate powder equal to the centrifugal force exerted by the vortex on the barium sulfate powder, and it becomes that the gravity of the barium sulfate powder plus the suction of the vortex on the barium sulfate powder is less than the centrifugal force exerted by the vortex on the barium sulfate powder. Therefore, the centrifugal force generated by the vortex on the barium sulfate powder can suck the processed nano barium sulfate powder out of the raw material, throw it into the vortex and be carried away by the air, while the unbroken barium sulfate powder will continue to stay in the center of the vortex under the interaction of gravity, suction, electromagnetic pulse impact force and centrifugal force until it is bombarded into nano barium sulfate powder and then sucked away by the airflow.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

10. A method for preparing a device for preparing nano-barium sulfate powder based on electric explosion method, characterized in that: The device for preparing nano-barium sulfate powder based on the electric explosion method according to any one of claims 1 to 9 is used, comprising the following steps: S1, connecting the device storing the barium sulfate powder to the input pipe (22), and after the connection is completed, starting the material taking component (4), and the reduction motor drives the fan blades in the fan (41) through the belt transmission component (45), and when the fan blades rotate, the barium sulfate powder will be sucked into the electric explosion chamber (21); S2, after the barium sulfate powder is sucked into the electric explosion chamber (21) by the fan (41), it moves along the route of the spiral guide convex strip (212), continues to move upward in a spiral route, and finally enters the discharge pipe (23), and then moves to the inside of the air inlet pipe (43); S3, remotely turning on the switch on the circuit board (28), so that the high-voltage package (27) energizes the coil (210), generating a high-frequency electromagnetic pulse irradiation downward, and under the action of the pulse energy, mechanical stress is generated inside the barium sulfate powder, and at the same time, the surface of the barium sulfate powder is also bombarded by the pulse, and finally the barium sulfate powder is deformed and broken into nano barium sulfate powder; S4. Under the action of electromagnetic pulse bombardment, the volume of barium sulfate powder becomes smaller and the mass becomes lighter, and the original dynamic balance is broken. At this time, the centrifugal force generated by the vortex on the barium sulfate powder can suck the processed nano barium sulfate powder out of the raw material and throw it into the vortex to be carried away by the air, while the unbroken barium sulfate powder will continue to stay in the center of the vortex under the interaction of gravity, suction, electromagnetic pulse impact force and centrifugal force until it is bombarded into nano barium sulfate powder and then sucked away by the airflow; S5. After being processed by the electric explosion component (2), the air carrying the nano-barium sulfate powder is discharged from the air outlet pipe (42). The nano-barium sulfate powder in the air is sent to the collection chamber (7) and filtered out, thereby completing the processing of the nano-barium sulfate powder.
