Description

Technical Field

[0001] This application relates to the field of water jetting technology, and more particularly to a vacuum pump water jetting device. Background Technology

[0002] A water jet is a device that uses fluid dynamics principles to achieve energy transfer, fluid transport, or mixing. Its core principle is to use the high-speed flow of a high-pressure fluid (driving fluid) to eject and mix a low-pressure fluid (the ejected fluid), ultimately converting kinetic energy into pressure energy through a diffuser section.

[0003] Water jets are mostly made of metal and plastic. Water jets made of plastic (such as polyvinyl chloride) have lower manufacturing costs and are more flexible in installation and use, making them widely used. However, in actual use, it has been found that the inlet chamber and mixing pipe of this type of water jet are easily flattened and deformed under the immersion of the jetting fluid and the action of the working flow, which affects the normal operation of the water jet. Utility Model Content

[0004] The purpose of this application is to provide a vacuum pump water ejector to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this application is as follows:

[0006] A vacuum pump water ejector includes an inlet chamber, a nozzle, a pressurizing chamber, a mixing chamber, and a diffusion chamber; the nozzle is located in the inlet chamber, the inlet chamber is provided with an ejector inlet, and the inner walls of the inlet chamber, the pressurizing chamber, and the diffusion chamber are all provided with bushings.

[0007] Preferably, the bushing has a spiral structure; there are multiple bushings, and the multiple bushings are spaced apart along the axial direction of the inlet chamber and the pressurization chamber.

[0008] Preferably, the mixing chamber is provided with a first spiral flow channel, and there are multiple first spiral flow channels, which are spaced apart along the inner peripheral wall of the mixing chamber.

[0009] Preferably, the first spiral flow channel includes a first directional flow channel and a second directional flow channel, the first directional flow channel and the second directional flow channel have opposite spiral directions, and a plurality of first directional flow channels and a plurality of second directional flow channels are arranged alternately.

[0010] Preferably, the nozzle has a second spiral flow channel inside, and there are multiple second spiral flow channels, which are arranged at intervals along the inner peripheral wall of the nozzle.

[0011] Preferably, the interior of the inlet chamber is provided with a dispersion channel corresponding to the jet inlet, and the dispersion channel is annular.

[0012] Preferably, the outer peripheral walls of the pressurizing chamber and the diffusion chamber are provided with clamps, and there are multiple clamps. The multiple clamps are arranged at intervals along the axial direction of the pressurizing chamber and the diffusion chamber, and the clamps are located between two adjacent bushings.

[0013] The vacuum pump water ejector disclosed in this application provides good support for the inlet chamber, pressurization chamber, and diffusion chamber by installing bushings on the inner walls of the inlet chamber, pressurization chamber, and diffusion chamber. When the inlet chamber and mixing pipe collapse due to immersion in the ejector fluid and the action of the working flow, the bushings ensure that the internal space remains in a normal state, thereby effectively extending the service life of the water ejector, ensuring safe and stable long-term operation, and further reducing the maintenance cost of the water ejector.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0022] like Figure 1-5 As shown, a vacuum pump water ejector includes an inlet chamber 1, a nozzle 10, a pressurizing chamber 3, a mixing chamber 4, and a diffusion chamber 5; the nozzle 10 is located inside the inlet chamber 1, the inlet chamber 1 is provided with an ejector inlet 2, and the inner walls of the inlet chamber 1, the pressurizing chamber 3, and the diffusion chamber 5 are all provided with bushings 30.

[0023] The nozzle 10 is located inside the inlet chamber 1, which is equipped with an ejector inlet 2 for introducing the ejected fluid. To enhance the stability and deformation resistance of the structure, the inner walls of the inlet chamber 1, the pressurization chamber 3, and the diffusion chamber 5 are all equipped with bushings 30.

[0024] The bushing 30 can be made of metal to provide sufficient strength and rigidity, such as titanium.

[0025] The bushing 30 can be fixed to the inner wall of each chamber by adhesive bonding to ensure a firm and reliable fit.

[0026] By installing bushings 30 on the inner walls of the inlet chamber 1, the pressurization chamber 3, and the diffusion chamber 5, when the inlet chamber 1 and the mixing pipe collapse under the immersion of the ejector fluid and the action of the working flow, the bushings 30 can effectively support the inlet chamber 1, the pressurization chamber 3, and the diffusion chamber 5, ensuring that the internal space remains in a normal state. This effectively extends the service life of the water jet, ensures safe and stable long-term operation, and further reduces the maintenance cost of the water jet.

[0027] In some further embodiments, the bushing 30 has a spiral structure; there are multiple bushings 30, which are spaced apart along the axial direction of the inlet chamber 1 and the pressurization chamber 3.

[0028] The spiral structure of the bushing 30 has good elasticity and support. Multiple bushings 30 are spaced apart along the axial direction to ensure full support for the chamber wall, so as to better distribute the pressure on the chamber wall and improve the coverage of effective support.

[0029] In some further embodiments, the mixing chamber 4 is provided with a first spiral flow channel 40, and there are multiple first spiral flow channels 40, which are spaced apart along the inner peripheral wall of the mixing chamber 4.

[0030] The first spiral flow channel 40 has a smooth surface to reduce fluid resistance. Multiple first spiral flow channels 40 are spaced circumferentially to ensure uniform distribution and thorough mixing of the entrained fluid and the driving fluid within the mixing chamber 4. The first spiral flow channels 40 guide the fluid to form a spiral flow within the mixing chamber 4, increasing the contact area and mixing time between the fluids, promoting thorough mixing of the driving fluid and the entrained fluid, and improving mixing efficiency.

[0031] In some further embodiments, the first spiral channel 40 includes a first directional channel (not shown in the figure) and a second directional channel (not shown in the figure), the first directional channel and the second directional channel have opposite spiral directions, and a plurality of first directional channels and a plurality of second directional channels are arranged alternately.

[0032] The first spiral flow channel 40 includes first-direction and second-direction flow channels with opposite spiral directions, and multiple first-direction flow channels are alternately arranged with multiple second-direction flow channels. The alternating flow channels form a more complex fluid flow path, enhance the mixing effect, and cause the fluid to generate rotation and shearing action in the mixing chamber 4, further improving the mixing efficiency.

[0033] In some further embodiments, the nozzle 10 is provided with a second spiral flow channel 11 inside, and there are multiple second spiral flow channels 11, which are arranged at intervals along the inner peripheral wall of the nozzle 10.

[0034] Multiple second spiral channels 11 are arranged at circumferential intervals to ensure uniform ejection and rotational flow of the driving fluid. This allows the driving fluid to form a rotating flow before ejection, enhancing its ability to entrain the fluid being ejected, improving ejection efficiency, and reducing energy loss.

[0035] In some further embodiments, the interior of the inlet chamber 1 is provided with a dispersion channel 12 corresponding to the jet inlet 2, and the dispersion channel 12 is annular.

[0036] The interior of the inlet chamber 1 is provided with a dispersing channel 12 corresponding to the ejector inlet 2, and the dispersing channel 12 is annular. The design of the annular dispersing channel 12 allows the ejected fluid to enter the inlet chamber 1 uniformly, avoiding local impact and eddy current generation, improving the uniformity and stability of the fluid, reducing energy loss, and facilitating the subsequent mixing and ejection process.

[0037] In some further embodiments, clamps (not shown in the figure) are provided on the outer peripheral walls of the pressurizing chamber 3 and the diffusion chamber 5. There are multiple clamps, which are arranged at intervals along the axial direction of the pressurizing chamber 3 and the diffusion chamber 5, and the clamps are located between two adjacent bushings 30.

[0038] The clamps are bonded and fixed to the outer peripheral walls of the pressurization chamber 3 and the diffusion chamber 5, ensuring a firm and reliable fit. Multiple clamps are spaced apart along the axial direction, providing comprehensive support for the pressurization chamber 3 and the diffusion chamber 5, enhancing their structural strength and resistance to deformation. When the inlet chamber 1, the pressurization chamber 3, or the diffusion chamber 5 collapses, the externally bonded clamps can effectively provide a certain degree of reinforcement to the outer peripheral walls, thereby further preventing collapse.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
