Description

Technical Field

[0001] The present invention relates to the technical field of water jet peening strengthening, and particularly relates to a non-submerged aerated cavitation jet generator that is convenient for replacing nozzles. Background Art

[0002] Non-submerged cavitation jet is a new type of two-phase jet that generates a large number of cavitation bubbles in the jet through artificial means to enhance the jet effect. When the cavitation jet contacts the target object, the cavitation bubbles collapse, and the chemical and mechanical effects accompanying the collapse of the cavitation bubbles bring huge destructive power. The principle of aerated cavitation is to introduce air at an appropriate position to make the water flow fully mix with the air to form an aerated jet rich in air bubbles. The aeration process is achieved by introducing compressed air into the nozzle. Cavitation jets are easy to generate and control. Traditional cavitation shot peening is submerged, but it cannot meet the processing requirements of large welded parts.

[0003] For this reason, Chinese Patent with the authorization announcement number CN114434343B discloses a non-submerged cavitation water jet nozzle structure, strengthening device and application thereof, which can form a cavitation effect equivalent to that in a submerged environment, and is suitable for carrying out cavitation jet impact on large welded parts in a non-submerged environment. Through the cavitator, gasket and the enlarged diameter section of the high-pressure inner nozzle, the cavitation effect is gradually enhanced to increase the cavitation jet impact pressure; through the nozzle support frame and the nozzle clamping mechanism, it is convenient to adjust the distance between the nozzle structure and the surface of the workpiece to be processed, and obtain the best cavitation effect under different pressures.

[0004] However, in order to adjust the impact pressure of the jet at the throat outlet, it is necessary to replace the embedded gemstone nozzles with different inner diameters to achieve the adjustment of the jet impact pressure. When the traditional generator replaces the nozzle, the steps are extremely complicated and the operation is rather inconvenient. Moreover, once the nozzle is not installed in place during the replacement process, it will affect the working stability of the generator. Summary of the Invention

Detailed implementation manners

[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] Refer to Figures 1 - 4 : A non-submerged aerated cavitation jet generator with a nozzle that is easy to replace, including a housing 1, a mounting base 2 and a clamping mechanism 3; both the housing 1 and the mounting base 2 are cylindrical, and a nozzle 21 is provided on the mounting base 2; when the mounting base 2 is inserted into the housing 1, the mounting base 2 is inserted and cooperated with the housing 1 through the clamping mechanism 3.

[0033] The present invention realizes the function of quickly disassembling and assembling the nozzle 21 through the housing 1, the mounting base 2 and the clamping mechanism 3. When replacing the nozzle 21, the mounting base 2 is quickly disassembled and assembled through the clamping mechanism 3, and then the nozzle 21 on the mounting base 2 is replaced. During the working process, according to the flow rate requirements in actual operations, nozzles 21 with different inner diameters and liquid outlet lengths are replaced to achieve different gas-liquid mixing effects and generate gas-liquid mixed jets in different states to achieve different impact pressures. A limiting ring 23 for restricting the insertion depth of the mounting base 2 is provided on the mounting base 2. When replacing the nozzle 21, first disconnect the connection of the clamping mechanism 3, remove the mounting base 2 from the housing 1, and then replace the nozzle 21 on the mounting base 2. Then insert the mounting base 2 into the housing 1 until the limiting ring 23 on the mounting base 2 abuts against the housing 1, and the clamping mechanism 3 connects the housing 1 and the mounting base 2.

[0034] Before working, slowly inject the liquid into the housing 1 while adjusting the liquid flow rate to the specified value. After a stable jet is formed at the liquid outlet of the nozzle 21, inject compressed air into the housing 1 and adjust the intake air flow rate so that a stable gas-liquid mixed jet is formed at the outlet of the housing 1. In the working state, the high-pressure liquid flows through the nozzle 21. Under the action of the flow channel sudden contraction structure, the fluid flow rate rapidly increases, the pressure energy is converted into kinetic energy, and the flow rate reaches the highest. The high-flow-rate liquid is ejected through the liquid outlet of the nozzle 21 to form a high-speed jet. Then a stable and uniform gas-liquid mixed jet is formed in the housing 1. Under the action of the ambient pressure, the cavitation bubbles in the gas-liquid mixed jet collapse downstream, generating a large pressure pulsation and releasing a strong impact pressure. To adjust the impact pressure of the jet at the outlet of the throat 12, nozzles 21 with different inner diameters can be replaced to achieve the adjustment of the jet impact pressure.

[0035] Refer to Figures 1 - 5 : An annular installation groove 11 is provided in the housing 1; an installation ring 31 is arranged in the installation groove 11; the end of the installation seat 2 is provided with a tail plate 22 that cooperates with the installation ring 31, and a notch for the tail plate 22 to pass through is provided on the installation ring 31. When the installation seat 2 is inserted and matched with the housing 1, the tail plate 22 of the installation seat 2 is clamped with the installation ring 31 through the clamping mechanism 3.

[0036] The present invention realizes the function of quickly connecting the housing 1 and the installation seat 2 when installing the nozzle 21 through the cooperation of the tail plate 22 and the installation ring 31. When installing the nozzle 21, first, the end of the installation seat 2 provided with the tail plate 22 is directed towards the housing 1 and axially inserted. Rotate the installation seat 2 circumferentially so that its tail plate 22 is aligned with the guiding notch of the installation ring 31 and then continue to push forward to make the tail plate 22 pass through the initial limiting area of the installation ring 31. Subsequently, rotate the installation seat 2 circumferentially for the second time until the tail plate 22 is clamped with the installation ring 31 through the clamping mechanism 3. At this time, the limiting ring 23 on the installation seat 2 abuts against the housing 1. The axial movement of the tail plate 22 is restricted by the coincidence of the tail plate 22 and the installation ring 31, and the connection between the installation seat 2 and the housing 1 is completed.

[0037] Refer to Figure 2 and Figure 5 : The clamping mechanism 3 includes a clamping component 32 and a control component 33; both the clamping component 32 and the control component 33 are arranged on the housing 1; the clamping component 32 is used to connect the installation ring 31 and the tail plate 22; the control component 33 is used to disconnect the connection of the clamping component 32.

[0038] The present invention realizes the functions of connecting and disconnecting the control mounting ring 31 and the tail plate 22 through the clamping component 32 and the control component 33, achieving the effect of quickly disassembling and assembling the nozzle 21. When replacing the type of the nozzle 21, first disconnect the connection of the clamping component 32 through the control component 33. Then the operator circumferentially rotates the mounting base 2 and applies a pulling force to the mounting base 2 away from the housing 1. As the mounting base 2 rotates, when the tail plate 22 of the mounting base 2 aligns with the housing 1 on the mounting ring 31, the mounting base 2 passes through the mounting ring 31 under the action of the pulling force. The operator continues to pull the mounting base 2 to pull out the mounting base 2 from the housing 1, completing the disassembly of the mounting base 2. Then the operator replaces the nozzle 21 on the mounting base 2. After the replacement is completed, the mounting base 2 is installed on the housing 1. During installation, align the end of the tail plate 22 of the mounting base 2 with the interface of the housing 1 and axially insert it. Circumferentially rotate the mounting base 2 so that its tail plate 22 is aligned with the guiding notch of the mounting ring 31 and then continue to push it forward to make the tail plate 22 pass through the initial limiting area of the mounting ring 31; then circumferentially rotate the mounting base 2 a second time until the clamping component 32 connects the mounting ring 31 and the tail plate 22. The replacement of the nozzle 21 is completed.

[0039] Refer to Figure 5 and Figure 6 : The mounting ring 31 is provided with a guiding rod 311 and a first elastic member 312; the guiding rod 311 is slidably engaged with the housing 1, and the guiding rod 311 is fixedly connected to the mounting ring 31; both ends of the first elastic member 312 are respectively connected to the mounting ring 31 and the housing 1.

[0040] The present invention realizes the functions of automatically controlling the movement and reset of the mounting ring 31 through the guiding rod 311 and the first elastic member 312, achieving the effect of facilitating the operator to install the mounting base 2 onto the housing 1. When installing the nozzle 21, the operator aligns the end of the tail plate 22 of the mounting base 2 with the interface of the housing 1 and axially inserts it. After the tail plate 22 contacts the mounting ring 31, it pushes the mounting ring 31 to move. During the movement, the guiding rod 311 guides the mounting ring 31 to avoid the mounting ring 31 rotating during the movement and keep the notch position of the mounting ring 31 unchanged, and the first elastic member 312 contracts under the pressure. Then the operator circumferentially rotates the mounting base 2, and the mounting base 2 drives the tail plate 22 to rotate. When the tail plate 22 aligns with the notch on the mounting ring 31, the mounting ring 31 moves towards the direction close to the mounting base 2 under the elastic force of the first elastic member 312 until the mounting ring 31 abuts against the wall of the mounting groove 11. After the operator senses the mechanical feedback generated by the reset of the mounting ring 31, the operator rotates the mounting base 2, and then connects the mounting ring 31 and the tail plate 22 through the clamping component 32 to complete the installation of the mounting base 2.

[0041] Refer to Figure 4 、 Figure 5 and Figure 7: The snap - fit component 32 includes a docking post 321 and a second elastic member 322; the docking post 321 is slidably mounted on the mounting ring 31, and a card slot 221 cooperating with the docking post 321 is provided on the tail plate 22; both ends of the second elastic member 322 are respectively connected to the mounting ring 31 and the docking post 321.

[0042] The present invention realizes the function of connecting the tail plate 22 and the mounting ring 31 through the docking post 321, the card slot 221 and the second elastic member 322. The tail plate 22 has elasticity. During the process of installing the nozzle 21, the mounting seat 2 is inserted into the housing 1, and after the tail plate 22 on the mounting seat 2 passes through the notch on the mounting ring 31, the operator rotates the mounting seat 2, and the mounting seat 2 drives the tail plate 22 to rotate. When the tail plate 22 contacts the docking post 321 and is squeezed, until the card slot 221 on the tail plate 22 aligns with the clamping post, the docking post 321 cooperates with the card slot 221 to restrict the circumferential rotation of the tail plate 22. When disassembling the nozzle 21, the operator pushes the docking post 321 through the control component 33, and the second elastic member 322 contracts under the thrust, so that the docking post 321 is separated from the card slot 221. Then the operator rotates the mounting seat 2 in the reverse direction, and the mounting seat 2 drives the tail plate 22 to rotate until the tail plate 22 rotates to the notch on the mounting ring 31, and then the operator pulls out the mounting seat 2 from the housing 1 to complete the disassembly of the nozzle 21.

[0043] Refer to Figure 5 and Figure 8 : The control component 33 includes a linear driver 331 and a push block 332; the linear driver 331 is arranged in the housing 1; the push block 332 is connected to the driving end of the linear driver 331; when the linear driver 331 drives the push block 332 to move towards the docking post 321, it pushes the docking post 321 until the docking post 321 is separated from the card slot 221.

[0044] The present invention realizes the function of controlling the separation of the docking post 321 and the card slot 221 through the linear driver 331 and the push block 332. A controller for human - machine interaction is provided on the housing 1. The linear driver 331 is preferably a linear cylinder, and the linear driver 331 is electrically connected to the controller. When disassembling the nozzle 21, the operator sends a signal to the linear driver 331 through the controller. After receiving the signal, the linear driver 331 drives the push block 332 to move towards the docking post 321, and then pushes the docking post 321 to move through the push block 332. The second elastic member 322 contracts under the pressure until the docking post 321 is separated from the card slot 221. Then the operator rotates the mounting seat 2 so that the tail plate 22 aligns with the notch on the mounting ring 31, and then pulls out the mounting seat 2. Then the controller sends a signal to the linear driver 331, and the linear driver 331 controls the push block 332 to reset. The docking post 321 resets under the elastic force of the second elastic member 322.

[0045] Reference Figure 5 and Figure 8 : A connecting ring 333 is provided in the installation groove 11, and a convex block 3331 is provided on the connecting ring 333. The convex block 3331 is connected to the docking column 321.

[0046] The present invention realizes the function of connecting multiple docking columns 321 through the connecting ring 333. Through the setting of the connecting ring 333, when the linear actuator 331 drives the push block 332 to extend, the push block 332 pushes the connecting ring 333 to move, and then drives multiple docking columns 321 to move synchronously through the connecting ring 333. There are at least three docking columns 321, and multiple docking columns 321 are circularly arrayed about the axis of the housing 1. Each docking column 321 is connected to a second elastic member 322, and multiple docking columns 321 are all connected to the connecting ring 333. There are three linear actuators 331 and push blocks 332, and multiple linear actuators 331 and push blocks 332 are circularly arrayed along the axis of the housing 1. When disassembling the nozzle 21, the operator sends a signal to the linear actuator 331 through the controller. After receiving the signal, the linear actuator 331 drives the push block 332 to extend. After the push block 332 contacts the connecting ring 333, it pushes the connecting ring 333, and then drives multiple docking columns 321 to move through the connecting ring 333 until the docking column 321 is separated from the card slot 221.

[0047] Reference Figure 4 、 Figure 9 and Figure 10 : A threaded pipe 211 is connected to the nozzle 21; an internal thread sleeve is provided on the mounting seat 2, and the threaded pipe 211 is threadedly connected to the internal thread sleeve.

[0048] The present invention realizes the function of connecting the nozzle 21 and the mounting seat 2 through the threaded pipe 211 and the internal thread sleeve. The jet flow channel on the nozzle 21 has a diameter-expanded section 212. When high-pressure water flow passes through the nozzle 21, attached cavitation is generated on the inner wall of the diameter-expanded section 212, which helps the cavitation bubbles to grow and further enhances the cavitation effect. After removing the mounting seat 2, the operator rotates the nozzle 21. Since the nozzle 21 is threadedly connected to the internal thread sleeve of the mounting seat 2 through the threaded pipe 211, when the nozzle 21 is rotated, the threaded pipe 211 is driven to rotate until the threaded pipe 211 is separated from the internal thread sleeve, completing the disassembly of the nozzle 21. Through the threaded connection design, the position of the nozzle 21 can be stabilized while quickly installing the nozzle 21. And it makes the axis of the nozzle 21 collinear with the axis of the mounting seat 2, stabilizing the jetting effect of the high-pressure jet flow.

[0049] Reference Figure 1 and Figure 2 : A throat pipe 12 is provided on the housing 1; a suction chamber 13 is provided inside the housing 1, and the suction chamber 13 is communicated with the throat pipe 12; an air inlet hole 14 communicated with the suction chamber 13 is opened on the housing 1.

[0050] The present invention realizes the function of introducing compressed gas into the housing 1 through the throat tube 12, the suction chamber 13, and the air inlet hole 14. The throat tube 12 is detachably arranged on the housing 1. Before operation, liquid is slowly injected into the aerated cavitation jet generator, and at the same time, the liquid flow rate is adjusted to the target value; after a stable jet is formed at the liquid outlet of the nozzle 21, air is injected into the suction chamber 13, and the air inlet flow rate is adjusted to an appropriate value to form a stable gas-liquid mixed jet at the outlet of the throat tube 12. During operation, high-pressure liquid flows through the nozzle 21. Under the action of the flow path sudden contraction structure, the fluid flow rate rapidly increases, and the pressure energy is converted into kinetic energy, reaching the highest flow rate; the high-flow-rate liquid is ejected through the liquid outlet of the nozzle 21 to form a high-speed jet and flow into the suction chamber 13; in the suction chamber 13 filled with gas, the high-speed jet generates strong shear and entrainment effects with the gas, the jet interface fluctuates, and a large amount of gas is entrained into the throat tube 12; after the jet passes through the inlet of the throat tube 12, under the action of the wall surface of the throat tube 12, the fluid vortex increases, the liquid interface quickly becomes unstable and breaks into discrete droplets, and strong mixing occurs with the gas; after the development of the throat tube 12 section, the mixing degree between the gas and the liquid increases, and a uniform gas-liquid mixed jet is formed at the outlet of the throat tube 12; under the action of the ambient pressure, the cavitation bubbles in the gas-liquid mixed jet collapse downstream, generating a large pressure pulsation and releasing a strong impact pressure. To adjust the impact pressure of the jet at the outlet of the throat tube 12, nozzles 21 with different inner diameters, nozzle bodies 21 with different liquid outlet section lengths, and throat tubes 12 with different length-diameter ratios can be replaced to achieve the adjustment of the jet impact pressure.

[0051] Refer to Figure 2 , Figure 3 , Figure 9 and Figure 10 : An inner ring 15 is provided in the housing 1, and a sealing ring 16 is installed on the inner ring 15; when the mounting seat 2 is installed into the housing 1, the mounting seat 2 abuts against the sealing ring 16.

[0052] The present invention realizes the function of improving the sealing performance at the abutting part of the mounting seat 2 and the housing 1 after installing the nozzle 21 through the inner ring 15 and the sealing ring 16. The sealing ring 16 is made of rubber, and a washer is provided between the sealing ring 16 and the inner ring 15. The washer is made of graphite, and the graphite washer can reduce the frictional resistance when the mounting seat 2 rotates, enabling the operator to smoothly rotate the mounting seat 2 when disassembling and assembling the mounting seat 2. In the working state, when the operator inserts the mounting seat 2 into the housing 1 and connects the mounting seat 2 and the housing 1 through the clamping mechanism 3, the end of the mounting seat 2 abuts against the sealing ring 16, and then the sealing performance of the connection is improved through the deformation performance of the sealing ring 16.

[0053] The above embodiments only represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
