An unlocking module utilizes a hydraulic jack inside the tank to drive each opening and closing mechanism to slide and unlock synchronously and quickly.

The hydraulic jack section includes a hydraulic jack and a hydraulic jack rod movably disposed within the hydraulic jack cylinder body.

[0025] Preferably, each of the upper and lower parts of the hydraulic cylinder is connected to and extends a set of hydraulic pipes, wherein the upper set of hydraulic pipes is matched with the upper position of the opening and closing mechanism to cooperate with the hydraulic top part to provide the driving force for sliding unlocking from the upper part of the opening and closing mechanism, and the lower set of hydraulic pipes is matched with the lower position of the opening and closing mechanism to cooperate with the hydraulic top part to provide the driving force for sliding unlocking from the lower part of the opening and closing mechanism; correspondingly, the upper and lower parts of the rotating shaft are each connected to a sliding part.

[0026] The beneficial effects of this utility model are as follows: (1) This utility model is achieved by uniformly distributing exhaust sections around the tank body and sealing the exhaust sections with matching opening and closing mechanisms inside the tank body. A gas supply module is set up to supply high-pressure gas required for the gas explosion into the tank body. The opening and closing mechanisms are designed to be eccentrically rotated on the tank body and slide back and forth relative to the exhaust sections. With the help of the unlocking module, the hydraulic top inside the tank is used to drive each opening and closing mechanism to slide and unlock synchronously and quickly. Then, the strong pressure difference inside and outside the tank is used to drive each opening and closing mechanism to rotate instantaneously and open the exhaust section synchronously, so as to achieve synchronous instantaneous explosion of the tank body around the circumference. The structure is ingenious and compact, and can effectively seal the tank by using the high pressure inside the tank. In turn, it can achieve a higher pressure value and a better flash explosion effect. The two are complementary, ingeniously designed, and highly practical. The maximum pressure inside the tank in this utility model can reach 10MPa (nitrogen).

[0027] (2) This utility model achieves simultaneous instantaneous exhaust explosion in all directions by evenly distributing several exhaust sections around the tank body, which is more uniform and has a better explosion effect. Furthermore, the unlocking structure is matched with several sets of exhaust sections evenly distributed around the circumference, which can provide a stable and reliable unlocking driving force for each exhaust section. The layout is compact and reasonable, and it is suitable for practical applications.

[0028] (3) This utility model is based on the principle of using high pressure to decompose materials in a flash explosion tank system. It makes full use of the powerful driving force of the high pressure inside the tank to achieve multiple driving functions. The unlocking of the opening and closing mechanism relies on the high pressure inside the tank as the driving force for sliding unlocking. Its locking can also rely on the high pressure inside the tank for full compression and locking. During the pressurization process inside the tank, the opening and closing mechanism can be pressed more tightly onto the exhaust part by gradually increasing the pressure, achieving full and effective sealing, ensuring the locking stability of the opening and closing mechanism itself and the effectiveness of its compression and sealing of the exhaust part, ensuring the subsequent instantaneous steam explosion effect, and using the high pressure inside the tank to drive the opening and closing mechanism to complete the rotation instantly so that the exhaust part opens instantly within milliseconds and completes the flash explosion. Combined with the high pressure gas inside the tank being released instantly through the exhaust part to generate huge explosive force, thereby achieving a super strong explosion effect. This utility model makes full use of the system's own characteristics to achieve multiple driving functions to realize and ensure the system's super strong flash explosion function effect. The design concept is very ingenious.

[0029] (4) In this utility model, the cylinder piston and the hydraulic cylinder piston of the unlocking module are rigidly coupled by hydraulic oil, and the piston area of ​​the cylinder is several times larger than that of the hydraulic cylinder piston. The pressure applied by the cylinder piston to the hydraulic cylinder piston is proportionally amplified according to the area ratio, and finally realizes the conversion of the pressure inside the tank to the higher pressure of the hydraulic cylinder, thereby providing a strong unlocking driving force, realizing the easy and quick opening and closing mechanism to be opened and unlocked, fully ensuring the instantaneous sliding unlocking of the opening and closing mechanism, and thus ensuring the instantaneous opening of the exhaust section, effectively avoiding the problem of insufficient force causing the exhaust section to fail to open and affecting the steam explosion effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Example 1 like Figures 1-3 As shown, a tank-type blasting device includes a tank body 1 and a gas supply module 2 for supplying high-pressure gas required for blasting into the tank body 1; it also includes: an opening and closing mechanism 3, wherein a plurality of exhaust sections 11 are evenly distributed on the side wall of the tank body 1 along its circumference, and an opening and closing mechanism 3 is provided inside the tank body 1 to match each exhaust section 11 to close the exhaust section 11, and the opening and closing mechanism 3 is in a rotationally locked state when the exhaust section 11 is completely closed; and an unlocking module 4, wherein the unlocking module 4 is connected to the tank body 1, and the high-pressure gas inside the tank drives the opening and closing mechanism 3 to slide to release the rotational lock, and then the high pressure difference inside and outside the tank drives the opening and closing mechanism 3 to rotate to instantly open the exhaust section 11.

[0034] In this embodiment, on the one hand, an eccentric rotation fit structure is designed for the opening and closing mechanism 3 on the tank body 1. The high pressure inside the tank drives the opening and closing mechanism 3 to rotate eccentrically so as to open the exhaust section 11 instantaneously and synchronously, thereby realizing the wall breaking effect of the material. On the other hand, a sliding locking fit structure is designed for the opening and closing mechanism 3 on the tank body 1. Its locking design can ensure the stable sealing effect and equipment reliability during the pressurization process inside the tank. The unlocking module 4 is set to drive the opening and closing mechanism 3 to slide and unlock under the high pressure inside the tank. The structure is ingenious.

[0035] As a preferred option, such as Figure 6 As shown, a rotating groove 12 is provided on one side of the tank body 1 of the opening and closing mechanism 3, such as... Figure 4 As shown, the opening and closing mechanism 3 is eccentrically rotated relative to the exhaust section 11 and its rotating shaft 301 is biased towards the rotating slide groove 12. Thus, the opening and closing mechanism 3 is triggered to rotate and slide into the rotating slide groove 12 when subjected to a high pressure difference between the inside and outside of the tank, so as to open the exhaust section 11.

[0036] In this embodiment, an exhaust section 11 is provided on the tank body 1, and an opening and closing component 31 is provided to match the eccentric rotation of the exhaust section 11. A rotating slide groove 12 is provided on the eccentric side of the opening and closing component 31, so that when the other side of the opening and closing component 31 is subjected to high pressure inside the tank, it is triggered to rotate and slide into the rotating slide groove 12 to open the exhaust section 11.

[0037] As a preferred option, such as Figure 5 and Figure 10 As shown, the rotating slide 12 includes an arc portion 121 that is adapted to the rotation trajectory of the opening and closing mechanism 3 and guides the rotation of the opening and closing mechanism 3, and a stop portion 122 located at the end position of the arc portion 121 and limiting the rotation of the opening and closing mechanism 3.

[0038] In this embodiment, the rotation of the opening and closing assembly 31 is guided by the arc portion 121, and the stop portion 122 limits the rotation endpoint of the opening and closing assembly 31. The elastic element 33 is used to reverse and reset after the high pressure in the tank is released.

[0039] As a preferred option, such as Figure 5 As shown, the sealing part 311 of the opening and closing mechanism 3 is used to block the front end face 310 of the exhaust part 11. It is set as a slope to make way for the sealing part 311 to rotate and slide into the rotating slide groove 12; the exhaust part 11 is correspondingly inclined to match and seal with the front end face 310.

[0040] As a supplementary explanation, the fact that the front end face 310 is set as a sloping surface means that the distance from the end of the front end face 310 close to the rotating slide 12 to the rotation center of the sealing part 311 is L1, and the distance from the end of the front end face 310 away from the rotating slide 12 to the rotation center of the sealing part 311 is L2, where L1≥L2, in order to ensure that the end of the front end face 310 away from the rotating slide 12 can smoothly enter the rotating slide 12.

[0041] It is worth noting that the switching structure of the exhaust section 11 on the tank 1 in this embodiment adopts a purely mechanical structure. Its switching action is stable and the sealing performance is always guaranteed, resulting in a good gas explosion effect and good reusability. It can also use the high pressure inside the tank to achieve the effect of pressing and sealing the exhaust section 11 and opening it instantly. The design is ingenious and effective. By setting an eccentric sealing door structure, when the high pressure inside the tank is used as the driving force, a bending moment is generated, which can achieve smooth opening of the sealing door and instantaneous swing effect, thereby realizing the instantaneous opening of the exhaust section 11 and ensuring the gas explosion effect.

[0042] As a preferred option, such as Figures 7-8 As shown, the opening and closing mechanism 3 includes: an opening and closing assembly 31, which includes a sealing part 311 and a rotating shaft part 301. The rotating shaft part 301 is connected to the rear end of the sealing part 311 to form an eccentric structure; and a locking assembly 32, which includes a sliding part 321 rotatably mounted on the rotating shaft part 301. The tank body 1 is provided with a slide rail 13 and a slot 14. The sliding part 321 is slidably mounted in the slide rail 13. The slot 14 is recessed in the inner side of the exhaust part 11. When subjected to force in the front-back direction, the sliding part 321 is triggered to slide so that the sealing part 311 is locked in the slot 14 to be rotated and locked or disengaged from the slot 14 to release the rotation lock.

[0043] See Figure 4 In one specific embodiment, the sealing part 311 and the rotating shaft part 301 located about 12cm away from the exhaust part 11 are an integrated structure. There is an eccentricity L between the center line of the exhaust part 11 and the center line of the rotating shaft. The sealing part 311 and the rotating shaft part 301 are rigidly connected. The vertical distance between the axis of the rotating shaft part 301 and the plane where the sealing part 311 is located is about 12cm, and there is an eccentricity (i.e., lateral offset) between the projection center of the rotating shaft part 301 on the plane where the sealing part 311 is located and the pressure-bearing center of the sealing part 311. Based on this structure, the driving principle of the opening and closing component 31 is as follows: when the rotating shaft part 301 is unlocked, the pressure difference (ΔP) inside and outside the tank acts on the sealing part 311, and the pressure applied to the sealing part 311 inside the tank is perpendicular to the exhaust part 11. The total pressure is P. Due to the eccentricity L, the pressure difference load is converted into rotational torque (T=pressure difference × pressure-bearing area × eccentricity), thereby pushing the sealing part 311 to rotate and open the exhaust part 11.

[0044] It is worth noting that the core technology of the exhaust opening and closing structure in this embodiment is to utilize pressure difference for self-drive, without the need for additional power, and the structure is simple. The eccentricity is a key parameter for torque generation, and the pressure difference and pressure-bearing area need to be matched to ensure that the sealing mechanism can be opened reliably.

[0045] In this embodiment, a sliding locking mechanism 3 is designed on the tank body. Specifically, the locking component 32 is slidably installed on the slide rail 13 of the tank body 1. When the locking component 32 slides toward the exhaust section 11, the opening and closing component 31 can be locked in the slot 14 for rotational locking. This locking design ensures that the opening and closing mechanism 3 will not rotate during the pressurization process inside the tank, ensuring a stable seal for the exhaust section 11. Furthermore, since the opening and closing mechanism 3 is installed inside the tank body 1, as the pressure inside the tank gradually increases, the opening and closing mechanism 3 can be pressed more tightly against the exhaust section, achieving a sufficient and effective seal. This ensures the locking stability of the opening and closing mechanism 3 itself and the effectiveness of its sealing of the exhaust section 11. The locking component 32 is then driven to slide out of the slot 14 by the unlocking module 4, which is configured to unlock the mechanism.

[0046] As a preferred option, such as Figure 2 As shown, the gas supply module 2 includes: at least one set of air inlet pipes 21 connected to the gas supply device, the air inlet pipes 21 leading into the tank body 1; and a solenoid valve A22, the solenoid valve A22 being disposed on the pipeline of the air inlet pipes 21.

[0047] Preferably, the air inlet pipe 21 is provided with at least two sets to accommodate different gases. In this embodiment, the gas / steam is supplied to the tank directly from a high-pressure nitrogen tank; if steam is required, it is supplied via a pipeline boiler.

[0048] In some embodiments, the solenoid valve A22 is a pilot-operated gas solenoid valve A.

[0049] As a preferred option, such as Figure 1 As shown, it also includes a feeding and discharging module. The tank body 1 has a material inlet 15. The feeding and discharging module includes a material cylinder 51 and a tank cover 52. The material cylinder 51 is used to carry the material to be blasted and enters and exits the tank body 1 through the material inlet 15. Mesh holes are distributed on its side wall. The tank cover 52 seals the material inlet 15.

[0050] Preferably, or as an improvement, the can lid 52 adopts an internal can lid structure to seal the feed inlet 15 from the inside of the can.

[0051] In one implementation, the can lid 52 has a built-in elliptical structure. The feed port 15 is also set to be elliptical, and the elliptical size of the can lid 52 is larger than that of the feed port 15. During installation, the short side of the ellipse of the can lid 52 is tilted to correspond to the long side of the ellipse of the feed port 15. After being inserted by the control of the robot, it is placed flat and then rotated 90 degrees to complete the installation of the can lid 52. Then, the can lid 52 is sealed by lifting and pressing it with the robot and setting a polytetrafluoroethylene sealing ring on the mating surface of the can lid 52 and the feed port 15.

[0052] It is worth noting that, in the closed state, the high pressure inside the tank assists the opening and closing mechanism 3 in fully pressing and sealing the exhaust section 11, and assists the tank cover 52 in fully pressing and sealing the material port 15. The greater the pressure, the better the sealing effect.

[0053] As a preferred option, such as Figure 7 As shown, the opening and closing mechanism 3 further includes an elastic element 33, which is connected between the tank body 1 and the opening and closing assembly 31. Its elastic force causes the opening and closing assembly 31 to reverse and reset from the rotating slide groove 12 to close the exhaust section 11, and causes the sealing section 311 to be locked in the slot 14 and pressed against the exhaust section 11.

[0054] In this embodiment, by setting the elastic element 33, the opening and closing assembly 31 is simultaneously reversed and reset to close the exhaust section 11 and slid reset to cooperate with the exhaust section 11 for sealing and locking. The structure is simple and the action is ingenious to achieve rapid self-reset and good effect.

[0055] When the opening and closing mechanism 3 is unlocked, it slides out of the slot 14 to complete the unlocking. During the process, the elastic element 33 is stretched and stored. When the high pressure inside the tank is fully released, the elastic element 33 releases its elastic force to drive the opening and closing mechanism 3 to slide back and reset. When the exhaust section 11 is opened, the opening and closing mechanism 3 rotates and slides into the rotating groove 12. During the process, the elastic element 33 on one side is stretched and stored, and the elastic element 33 on the other side is compressed and stored. So when the high pressure inside the tank is fully released, the elastic elements 33 on both sides release their elastic force to jointly drive the opening and closing mechanism 3 to reverse and reset.

[0056] As a preferred option, such as Figure 7 As shown, the exhaust section 11 includes an exhaust section 111 opened on the tank body 1 and a sealing ring 112 that is sealed to the inner side of the tank body 1 of the exhaust section 111. Under the elastic force of the elastic member 33, the opening and closing assembly 31 presses against the sealing ring 112 to effectively seal the exhaust section 111.

[0057] In a preferred embodiment, the main body of the sealing ring 112 is made of copper, and the contact side between the copper main body and the exhaust part 11 is made of soft PTFE, which is a soft metal that provides a sealing function and is corrosion resistant, making it suitable for gas explosion conditions of various materials.

[0058] As a preferred option, such as Figure 8 As shown, connecting plates 302 are provided at both ends of the rotating shaft 301. Each connecting plate 302 is connected to the corresponding tank body 1 with an elastic element 33, and the axial direction of the elastic element 33 is arranged along the front-back direction.

[0059] Example 2 The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that: As a preferred option, such as Figure 2 , Figure 7 , Figure 9 as well as Figure 11 As shown, the unlocking module 4 includes an air pipe 41, an air cylinder 42, a hydraulic cylinder 43, an oil pipe 44, and a hydraulic top part 45 connected in sequence. The air inlet of the air pipe 41 is connected to the tank body 1, and the air outlet is connected to the cylinder body of the air cylinder 42. The cylinder bodies of the air cylinder 42 and the hydraulic cylinder 43 are interconnected, and a piston 420 is movably disposed therein. The cross-sectional area of ​​the cylinder body of the air cylinder 42 and the cross-sectional area of ​​the piston 420 inside it are correspondingly larger than the cross-sectional area of ​​the cylinder body of the hydraulic cylinder 43 and the cross-sectional area of ​​the piston 420 inside it. The hydraulic top part 45 includes a hydraulic top 451 and a hydraulic top rod 452 movably disposed in the cylinder body of the hydraulic top 451. The cylinder body of the hydraulic cylinder 43 and the cylinder body of the hydraulic top 451 are connected by the oil pipe 44. The hydraulic top rod 452 extends out of the cylinder body of the hydraulic top 451 and is connected to the locking component 32. A solenoid valve B46 is also provided on the oil pipe 44.

[0060] As a supplementary explanation, the piston of cylinder 42 and the piston of hydraulic cylinder 43 are rigidly coupled by hydraulic oil, and the piston area of ​​cylinder 42 is larger than that of hydraulic cylinder 43.

[0061] When the unlocking action of the opening and closing mechanism 3 is performed, the unlocking module 4 provides the unlocking driving force, which acts on the locking component 32 of the opening and closing mechanism 3 in the front-back direction, causing the locking component 32 to slide about 5-6mm and thus disengage from the slot 14.

[0062] In this embodiment, the pressure of cylinder 42 comes from the pressure inside the tank and applies pressure to hydraulic cylinder 43. The pressure introduced by cylinder 42 is multiplied after being transmitted to hydraulic cylinder 43. The pressure inside hydraulic cylinder 43 is greater than the pressure inside the tank. As a result, hydraulic top part 45 can easily and quickly push open (create pressure difference) and unlock (after opening and closing component 31 is dislodged from slot 14 without obstruction, an eccentric torque is generated to automatically rotate and pop open the opening and closing component 31 without power). This provides a strong unlocking driving force, similar to the effect of a jack, which fully ensures the instantaneous sliding unlock of opening and closing mechanism 3 and thus ensures the instantaneous opening of exhaust part 11. This effectively avoids the problem of exhaust part failing to open due to insufficient force, which affects the steam explosion effect.

[0063] As a supplementary explanation, such as Figure 11 As shown, the piston of cylinder 42 and the piston of hydraulic cylinder 43 are rigidly coupled through hydraulic oil. Since the piston area of ​​cylinder 42 (cylinder A) is several times larger than the piston area of ​​hydraulic cylinder 43 (hydraulic A), when the piston rod of cylinder 42 applies a thrust to the piston of hydraulic cylinder, according to Pascal's principle, the hydraulic pressure (hydraulic P) in hydraulic cylinder will be amplified proportionally according to the area ratio, ultimately realizing the conversion of the pressure inside the tank to a higher pressure in hydraulic cylinder. The amplification factor is directly determined by the piston area ratio.

[0064] In this embodiment, the core mechanism of the unlocking module 4 lies in the pressure source. It integrates a gas-liquid conversion unit and does not require an external power source. That is, the pressure of the cylinder 42 is directly taken from the inside of the tank 1 without the need for an external power source. Moreover, the pressure is amplified through a purely mechanical structure. After the pressure is amplified, the unlocking force is strong and the action is rapid. It is suitable for quickly unlocking and opening the actuator (i.e., the opening and closing component 31 of the flash explosion device in this embodiment) that relies on the pressure inside the tank to drive the actuator. It has the advantages of rapid response and compact structure, and has no electrical components, which can fully adapt to high temperature and high pressure environments.

[0065] As a preferred implementation, during the pressurization process inside the tank, the system controls the adjustable pressure solenoid valve B46 to pre-release a small pressure on the sealing door, so that the opening and closing mechanism 3 bears the pre-opening force and is in a critical unlocking state. This pre-opening force can eliminate the gap between the force transmission components and reduce the impact force between the components at the moment the sealing door opens. After a few seconds, the pressure is released, so that the sealing door can be rotated and the exhaust section can be opened instantly, achieving instantaneous bursting. That is, after the pressurization inside the tank is completed, the opening and closing mechanism can be quickly unlocked and the exhaust section can be opened instantly.

[0066] When detonation is required, the unlocking module 4 pushes the opening / closing assembly 31 approximately 5mm, disengaging it from the exhaust section 11. At this time, the pressure difference between the inner and outer sides of the opening / closing assembly 31 generates a force, which, combined with the eccentricity of the rotating shaft, forms a torque. Due to the 5mm high limit stop, when the opening / closing assembly 31 moves more than 5mm, the stop fails. Driven by the torque, the rotating shaft 301 drives the sealing section 311 to rotate rapidly, and the exhaust section 11 opens quickly, achieving a highly efficient flash detonation.

[0067] Preferably, the oil pipe 44 includes a main oil pipe 441 and a plurality of branch oil pipes 442 connected to the main oil pipe 441 and matched one-to-one with the opening and closing mechanism 3. The solenoid valve B46 is disposed on the main oil pipe 441. A branch oil cylinder 443 is connected between the main oil pipe 441 and the branch oil pipes 442. The oil outlet end of each branch oil pipe 442 is connected to a hydraulic top part 45.

[0068] In some embodiments, the slide rails 13 are provided on both sides of the hydraulic jack 451 and the hydraulic jack rod 452 as limiting walls. Their main function is to provide limiting and guiding when the hydraulic jack rod 452 drives the locking component 32 to move. Since the hydraulic jack rod 452 is subjected to a large force, setting the limiting walls can ensure that the hydraulic jack rod 452 drives the locking component 32 to move in a straight line, avoiding damage to the hydraulic jack 451 due to deviation.

[0069] In some embodiments, the solenoid valve B46 is an adjustable hydraulic oil solenoid valve.

[0070] In some embodiments, the pneumatic cylinder 42 and the hydraulic cylinder 43 are an integral structure, and the two together constitute a pneumatic-hydraulic booster cylinder. The pneumatic pipe 11, which communicates with the tank body 1, connects to the pneumatic portion of the pneumatic-hydraulic booster cylinder. The hydraulic cylinder portion is connected to the main oil pipe 441, which sequentially connects to the adjustable hydraulic solenoid valve B46 and the distributor cylinder 443. The distributor cylinder 443 is connected to multiple hydraulic jacks 45 via multi-way distributor pipes 442. The hydraulic jack rods 452 of the hydraulic jacks 45 are connected to the locking assembly 32. In the pneumatic-hydraulic booster cylinder, the piston area inside the pneumatic cylinder is several times the piston area inside the hydraulic cylinder.

[0071] Example 3 The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that: like Figure 1 As shown, Figures 2-3 As shown, preferably, the tank body 1 has several sides evenly distributed around its circumference, and each side is provided with a set of exhaust sections 11, and each set includes several exhaust sections 11 evenly distributed side by side.

[0072] In this embodiment, by evenly distributing several exhaust sections 11 around the tank body 1, simultaneous explosions in all directions are achieved, resulting in a more uniform explosion and a better explosion effect.

[0073] Example 4 The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that: As a preferred option, such as Figures 2-3 As shown, the tank body 1 is provided with N sets of exhaust sections 11 evenly distributed around its circumference, each set including M exhaust sections 11 arranged side by side, and the unlocking module 4 is provided with N / 2 units, with each pair of adjacent sets of exhaust sections 11 sharing one unlocking module 4.

[0074] Preferably, the oil distribution cylinder 443 of each unlocking module 4 is arranged between the two sets of exhaust sections 11 that are shared. Each oil distribution cylinder 443 is connected to and extended to both horizontal sides with a set of oil distribution pipes 442 that match the set of exhaust sections 11 on that side. Each set of oil distribution pipes 442 includes M oil distribution pipes 442 to match the opening and closing mechanism 3 one by one.

[0075] In one specific implementation, N=4, M=4.

[0076] In a preferred embodiment, the oil distribution cylinder 443 is arranged vertically and the oil distribution pipe 442 is arranged horizontally.

[0077] Preferably, each of the upper and lower sides of the hydraulic cylinder 443 is connected to and extends a set of hydraulic pipes 442, wherein the upper set of hydraulic pipes 442 is matched with the upper position of the opening and closing mechanism 3 to cooperate with the hydraulic top part 45 to provide the driving force for sliding unlocking from the upper part of the opening and closing mechanism 3, and the lower set of hydraulic pipes 442 is matched with the lower position of the opening and closing mechanism 3 to cooperate with the hydraulic top part 45 to provide the driving force for sliding unlocking from the lower part of the opening and closing mechanism 3; correspondingly, the upper and lower parts of the rotating shaft part 301 are respectively connected to a sliding part 321.

[0078] In this embodiment, by matching several groups of exhaust sections 11 evenly distributed in the circumference with the unlocking module 4 of the above-described structure, a stable and reliable unlocking driving force can be provided for each exhaust section 11, and the layout is compact and reasonable, suitable for practical applications.

[0079] Example 5 The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that: like Figure 8 As shown, preferably, the opening and closing mechanism 3 is provided with a hollow part 313 to balance the left and right pressure difference when the opening and closing mechanism 3 rotates to open the exhaust part 11.

[0080] Preferably, a plurality of the hollowed-out portions 313 are provided at the connection between the rear part of the sealing portion 311 and the pivot portion 301.

[0081] Based on the principles of fluid mechanics, combined with Figure 5 As shown, at the instant the opening and closing mechanism 3 rotates to open the exhaust section 11, a pressure difference is generated on the left and right sides of the opening and closing mechanism 3, and the air pressure on the left side is released first due to the opening of the exhaust section 11. Therefore, the pressure on the left side of the opening and closing mechanism 3 is less than the pressure on the right side, and a negative pressure is formed on the left side. Under this situation, the pressure on the right side acts on the opening and closing mechanism 3, thereby generating resistance to the continued rotation of the opening and closing mechanism 3 and forming rotational resistance. By setting the hollow part 313, the pressure on the left and right sides of the opening and closing mechanism 3 can be made consistent, thereby effectively resolving the rotational resistance caused by the negative pressure.

[0082] At the moment the opening and closing mechanism 3 is opened, the airflow velocity is high on the side near the exhaust section 11 and low on the other side, resulting in negative pressure on the exhaust section 11 side. This causes the opening and closing mechanism 3 to be subjected to a thrust in the direction of the exhaust section 11. To reduce this thrust, the side wall of the opening and closing mechanism 3 is not designed as a single plate, but rather has openings, i.e., hollowed-out portions 313, on the side wall plate.

[0083] During work: After the material to be blasted is loaded into the tank 1 through the feed inlet 15, the tank cover 52 seals the feed inlet 15, and the exhaust part 11 is sealed by the opening and closing assembly 31. The gas supply module 2 introduces the high-pressure gas required for blasting into the tank 1, creating a high-pressure environment inside the tank. During the pressurization process inside the tank, the pressure gradually increases, pressing the opening and closing mechanism 3 against the exhaust part 11 for sealing. At the same time, the solenoid valve B44 of the system-controlled unlocking module 4 opens to a certain extent. The gas pipe 41 leads the high pressure inside the tank to the cylinder 42, and then the hydraulic cylinder 43 generates hydraulic driving force to act on the locking assembly 32, causing the opening and closing assembly 31 to slide to its critical unlocking state. After the pressurization inside the tank is completed, the system-controlled solenoid valve B44 is fully opened, thereby driving the unlocking module 4 to open. The closing component 31 slides out of the slot 14, instantly unlocking, at which point the elastic element 33 stores force. At the instant the opening and closing component 31 unlocks, the high pressure inside the tank acts on the opening and closing component 31, triggering it to rotate and slide into the rotating groove 12, thereby instantly opening the exhaust section 11. At this time, the elastic element 33 stores force, and the high-pressure gas inside the tank is released instantly through the exhaust section 11, generating a huge explosive force, which fully vaporizes and decomposes the material in the cylinder. After the high pressure inside the tank is fully released, the elastic element 33 releases its elastic force, driving the opening and closing mechanism 3 to first reverse and reset to face the exhaust section 11, and then slide and reset to lock into the slot 14 to achieve a seal and lock. The tank cover 52 is opened, and the cylinder 51 containing the material that has completed the flash explosion is taken out.

[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
