Description

Technical Field

[0001] The present invention relates to a solid processing device and method, and particularly to a processing device and method capable of generating micro-explosion on solid materials. Background Art

[0002] Generally, solid materials often need to be appropriately decomposed to obtain the required micro-solid materials for utilization. For example, graphene micro-solid materials are thin films with a thickness of only one carbon atom and can be exfoliated by appropriately decomposing the layered structure of graphite. Generally, in the industry and academia, the methods for preparing graphene mostly use the oxidation-reduction method supplemented by ultrasonic oscillation, and then reduce graphene oxide to graphene, or directly exfoliate graphite into graphene by ultrasonic waves. The oxidation-reduction method is a way to mass-produce graphene. It uses an oxidant to oxidize graphite into graphite oxide, making the tightly connected graphite layer structure become looser, and then uniformly dispersing it into a graphene oxide solution by mechanical energy such as ultrasonic oscillation. Finally, functional groups containing oxygen atoms are removed by high temperature or a reducing agent to complete the preparation of graphene. However, when preparing graphene by the oxidation-reduction method, both the oxidation and reduction processes will damage the structure of graphene. Therefore, the prepared graphene has more structural defects and its conductivity is much lower than that of general graphene. If graphite is directly exfoliated into graphene by ultrasonic waves, the graphene is often not completely exfoliated due to the uneven standing wave distribution of the ultrasonic oscillator. In addition, when the ultrasonic oscillator operates, the temperature of the graphene solution often rises, which also reduces the exfoliation rate of graphene and is not conducive to large-scale production.

[0003] For another example, solid materials such as rice straw and bamboo contain abundant fiber micro-solids. If the fibers of non-wood plants or waste wood can be properly developed and utilized, it will surely help relieve the pressure of "cutting down trees for papermaking". In the past, the methods for producing fibers from non-wood plants around the world mostly used chemical or semi-chemical treatment methods to decompose plants. However, the chemical decomposition of plants has the following disadvantages: (1) A large amount of silicate and high-viscosity black liquid are generated in the process, causing serious sequelae in the recovery system; (2) When recovering the waste liquid, the silicate affects the sedimentation of calcium carbonate, causing scale in the steam tank, and the black mucus will coat the pipelines of the evaporator with scaly substances, often requiring shutdown for cleaning; (3) The cooking machine will be in an unstable state, thus wasting fuel and increasing production costs.

[0004] Therefore, after observing the above disadvantages, the inventor of this case believes that there is still a need for further improvement, and thus this invention is created. Summary of the Invention

[0005] The object of the present invention is to provide a processing device and method for generating micro-blasting on solid materials. Through this processing device and method, the solid materials can be micro-blasted instantaneously when the bubbles in the nano-bubble liquid burst, so that the solid materials can be properly decomposed to obtain the effect of obtaining micro-solids.

[0006] To achieve the above object, the processing device for solid micro-blasting provided by the present invention includes a pressure barrel, which further includes an outer barrel body and a cover provided above the outer barrel body. An inner bladder is further provided inside the outer barrel body, which can expand and contract and deform under the change of pressure. The inlet and outlet of the inner bladder can be closed by the cover, and a through port is provided on the cover. An air inlet is provided on the outer barrel body; a gas-liquid mixing device is connected to the through port of the pressure barrel, which can send the nano-bubble liquid formed by mixing gas and liquid into the inner bladder, and a three-way valve and a pulse pressure control valve are provided between the gas-liquid mixing device and the inner bladder.

[0007] Further, a pressure pump is further provided between the gas-liquid mixing device and the pressure barrel.

[0008] Further, an air compressor device is further included, which is connected to the air inlet of the outer barrel body to provide high-pressure gas for the outer barrel body.

[0009] Further, the pulse pressure control valve is further connected to a time-domain pulse controller, which can control the opening and closing time and period of the pulse pressure control valve instantaneously, so that the high-pressure gas in the inner bladder can be sent out instantaneously in a high-pressure and high-speed manner through the pulse pressure control valve and discharged to the outside through the three-way valve.

[0010] To achieve the above object, the method for solid micro-blasting provided by the present invention includes the following steps: 1. Preparation step: Prepare a pressure barrel, which has an outer barrel body and an inner bladder provided inside the outer barrel body. The outer barrel body is connected to an air compressor device, and the inner bladder is connected to a gas-liquid mixing device, which can generate nano-bubble liquid; Placement step: Put the solid material to be processed into the inner bladder, and use the gas-liquid mixing device to send the nano-bubble liquid into the inner bladder, so that the solid material is fully immersed in the nano-bubble liquid, and the inner bladder is formed into a closed state with a certain pressure; Micro-blasting step: Instantaneously relieve the pressure of the inner bladder, so that the bubbles of the nano-bubble liquid penetrating into the fibers of the solid material instantaneously expand and burst due to the sudden drop of the pressure in the inner bladder, and then the solid material is properly decomposed into micro-solid materials; Finished product completion step: The micro-solids after micro-blasting are taken out from the inner bladder to obtain the decomposed micro-solid finished products.

[0011] Further, in the preparation step, the nano-bubble liquid provided by the gas-liquid mixing device is the nano-bubble liquid formed by oxygen-containing gas and water.

[0012] Further, in the placing step, the solid material is selected as rice straw.

[0013] Further, a pressurizing step is added between the placing step and the micro-blasting step. In this pressurizing step, high-pressure gas is injected into the outer barrel of the pressure barrel by a pneumatic device, so that there is a certain pressure between the outer barrel and the inner bladder.

[0014] Further, the pressure in the outer barrel is greater than the pressure in the inner bladder.

[0015] Thus, the solid material can be oxidized and decomposed by the micro-blasting generated instantaneously when the bubbles in the nano-bubble liquid burst, achieving the effect of obtaining the decomposed micro-solids. Description of the Drawings

[0042] Please refer to Figure 1 and 2 as shown, the processing equipment provided by a preferred embodiment of the present invention for micro-blasting solid materials includes:

[0043] A pressure barrel 10, which further includes an outer barrel body 11 and a cover 12 provided above the outer barrel body 11. An inner bladder 13 is further provided inside the outer barrel 11 and can expand and contract under the change of pressure. The inlet and outlet of the inner bladder 13 can be closed by the cover 12, and a through hole 121 is provided on the cover 12. In addition, an air inlet 111 is provided on the outer barrel body 11.

[0044] A gas-liquid mixing device 30 is connected to the through hole 121 of the pressure barrel 10. The gas-liquid mixing device 30 has an intake pipe 35 and a water inlet pipe 36, and liquid and gas can enter the gas-liquid mixing device 30. The gas-liquid mixing device 30 can mix gas and liquid into nanobubble liquid and send it into the inner bladder 13. A pressure pump 31, a three-way valve 32 and a pulse pressure control valve 33 are sequentially arranged between the gas-liquid mixing device 30 and the inner bladder 13. The pressure pump 31 can make the inner bladder 13 form a predetermined pressure. The three-way valve 32 can be switched to make the inner bladder 13 communicate with the gas-liquid mixing device 30, or make the inner bladder 13 in a closed state, or make the inner bladder 13 communicate with the outside. In addition, the pulse pressure control valve 33 is further connected to a time-domain pulse controller 34. The time-domain pulse controller 34 can control the instantaneous opening and closing time and cycle of the pulse pressure control valve 33, so that the high-pressure gas in the inner bladder 13 can be instantaneously sent out in a high-pressure and high-speed manner through the pulse pressure control valve 33 and discharged to the outside synchronously by the three-way valve 32.

[0045] Please refer to again Figures 3 to 5 As shown, the method for generating micro - blasting on solid materials provided by the preferred embodiment of the present invention includes the following steps:

[0046] Preparation step: Prepare a pressure barrel 10, which has an outer barrel body 11 and an inner bladder 13 disposed within the outer barrel body 10. The outer barrel body 11 is connected to an air compressor device 20, and the inner bladder 13 is connected to a gas - liquid mixing device 30. Moreover, the gas - liquid mixing device 30 is connected to a pressure pump 31, a three - way valve 32, and a pulse pressure control valve 33, so that the gas - liquid mixing device 30 can generate a nano - bubble liquid 300 with a certain pressure. In this embodiment, the nano - bubble liquid 300 is a nano - bubble liquid formed by an oxygen - containing gas and water, such as O2, O3, or a gas with OH-.

[0047] Placement step: Place a plurality of solid materials 200 into the inner bladder 13. In this embodiment, the solid material 200 is made of rice straw. First, switch the three - way valve 32 to make the gas - liquid mixing device 30 send the nano - bubble liquid into the inner bladder 13, so that the solid material 200 is fully immersed in the nano - bubble liquid 300. Then, switch the three - way valve 32 again to make the inner bladder 13 form a closed state with a certain pressure. According to the softness and hardness of the solid material, the pressure formed inside the inner bladder 13 is about 1 - 18 kg / cm3, and the bubbles formed by the gas - liquid mixing device 30 are about between 25 nm - 363 nm, so that the bubbles of the nano - bubble liquid 300 can penetrate into the fiber cell walls of the solid material 200, and the bio - glue of the solid material 200 can be oxidized by the oxidation of the nano - bubble liquid.

[0048] Micro - blasting step: Switch the three - way valve 32 and start the pulse pressure control valve to make the inner bladder 13 communicate with the outside atmosphere. At this time, the inner bladder 13 instantaneously releases pressure, so that the bubbles of the nano - bubble liquid that penetrate into the fiber cell walls of the solid material 200 instantaneously expand and burst due to the sudden drop in pressure of the inner bladder 13 and gush out to the outside atmosphere, thereby decomposing the solid material 200 into micro - solids 400, and the original nano - bubble liquid 300 is restored to a liquid 500 with almost no bubbles.

[0049] Finished product completion step: The micro - solids 400 formed by micro - blasting are taken out from the inner bladder 13, and the finished product of the micro - solids 400 is obtained.

[0050] Please refer to Figure 6 As shown, another preferred embodiment of the solid micro - blasting processing equipment provided by the present invention further includes an air compressor device 20 connected to the air inlet 111 of the outer barrel body 11 to provide high - pressure gas to the outer barrel body 11.

[0051] Please refer to Figure 7 as shown in the figure, which is another preferred embodiment of the method for generating micro-blasting on solid materials provided by the present invention. A pressurizing step is further added between the placing step and the micro-blasting step. In this pressurizing step, the air compressor device 20 injects high-pressure gas into the outer barrel 11 of the pressure barrel 10, so that there is a certain pressure between the outer barrel 11 and the inner bladder 13. The pressure in the outer barrel 11 must be greater than the pressure in the inner bladder 13. In the preferred embodiment of the present invention, the pressure formed in the outer barrel 11 is about 2-20 kg / cm 3 .

[0052] The technical means and achieved effects used in the present invention are described as follows:

[0053] In the present invention, the blasting effect generated instantaneously when the bubbles of the nano-bubble liquid burst destroys the cell wall of the solid material 200. And since the nano-bubble liquid generates micro-nano bubbles, hydroxyl radicals and single oxygen atoms in the water body through a powerful vortex motor and a strong electric field to dissociate molecular bonds. Among them, the hydroxyl radical (—OH) is an important active oxygen. From the molecular formula, it is formed by the hydroxyl group (OHˉ) losing an electron. Therefore, the hydroxyl radical has extremely strong electron ability, that is, oxidation ability (the oxidation potential reaches 2.8V, which is the second most powerful oxidant in nature after fluorine). Therefore, it can further oxidize and decompose the solid material 200 to form micro-solids 400.

[0054] Therefore, through the processing equipment and processing method of the present invention, the solid material 200 can be decomposed into micro-solids 400 without the use of chemical agents and without generating pollution.

[0055] The above-mentioned embodiments are only for illustrating the technical means of the present invention rather than limiting it. All equivalent modifications made by the present invention should be regarded as the protection scope of the present invention. The present invention is the first in this field and has the improvement of practical efficacy, so an application is filed according to law.
