Description
Technical Field
[0001] This utility model relates to the field of injector technology, and in particular to an injector with a precision control and delivery system. Background Technology
[0002] An ejector, also known as a jet vacuum pump, jet vacuum ejector, jet pump, water ejector, or vacuum ejector, is a vacuum-generating device that uses fluid to transfer energy and mass. It employs a pressurized water stream ejected through symmetrically distributed nozzles at a certain angle, converging at a focal point. Due to the extremely high velocity of the ejected water, pressure energy is converted into velocity energy, causing a pressure drop in the intake zone and creating a vacuum.
[0003] The hybrid power of the ejector comes from the high-speed jet of the working fluid. When the working fluid passes through the nozzle, the flow area decreases sharply, the flow velocity increases rapidly, and the pressure drops significantly, forming a local low-pressure zone. This entrains another phase of fluid and achieves mixing through flow field disturbance.
[0004] While the aforementioned technologies achieve the screening and weighing of coarse-grained soil, the gas-liquid mixing relies solely on the injector without stirring, which affects the mixing efficiency, process stability, and application performance in multiple dimensions. It also leads to disordered gas-liquid distribution, significant concentration differences, and a substantial decrease in overall mixing uniformity, making it less convenient to use. Therefore, an injector with a precise control and delivery system is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Reference Figures 1-3The present invention provides an embodiment of an injector with a precision control and delivery system, comprising an injector 1, a gas input pipe 4 whose inner diameter is perfectly matched with the size of the top interface of the injector 1 and whose inner wall is polished, and a liquid input pipe 3 whose installation position is about 5cm lower than the gas input pipe 4 is fixedly connected to the outer wall of the injector 1. This design allows the liquid to enter and form convection with the falling gas above, optimizing the initial state of the medium mixing. A nozzle control assembly 2 is provided on the top of the injector 1, and a mixing assembly 5 is provided inside the injector 1.
[0033] The mixing component 5 includes a filter screen 51 made of stainless steel woven mesh with a mesh diameter of 0.5 mm and a mesh count of approximately 32 meshes. This filter screen can block large particles without excessively hindering the flow of the medium. A fixing rod 52 is fixedly connected to the bottom of the filter screen 51, with its axis coinciding with the center of the filter screen 51. The fixing rod 52 is argon-arc welded to the filter screen 51. A bottom filter screen 56 with a mesh density greater than that of the filter screen 51 and a mesh diameter of 0.2 mm is fixedly connected to the bottom of the fixing rod 52. This bottom filter further filters out fine particles that may agglomerate after mixing, improving the purity of the medium and meeting the requirements of high-precision spraying. A retaining ring 55 is fixedly connected to the outer wall of the fixing rod 52, effectively limiting the axial displacement of the ring 53 on the fixing rod 52 and ensuring that the ring 53 rotates only around the fixing rod 52. The outer wall of the retaining ring 55 is rotatably connected to the ring 53. Four rings equidistantly distributed in a ring shape are fixedly connected to the outer wall of the ring 53. The outer wall of the blade has a 30° inclination angle. This angle design maximizes the utilization of the kinetic energy of the medium flow, increases the blade rotation speed, and enhances the stirring effect. The bottom of the filter screen 51 is snapped into the top of the injector 1, and the outer wall of the bottom filter screen 56 is attached to the inside of the injector 1. During the medium flow, it will drive the rotating blade 54 on the outer wall of the ring 53 in the mixing component 5 to rotate. The ring 53 is rotatably connected to the retaining ring 55 on the outer wall of the fixed rod 52, and can rotate stably around the fixed rod 52. The rotation of the rotating blade 54 can actively stir the gas and liquid. At the same time, the medium needs to pass through the top filter screen 51 and the bottom filter screen 56 in sequence. The filter screen 51 can filter impurities in the initially entering medium, and the bottom filter screen 56 further refines the medium particles and filters residual impurities after stirring. The combination of dual filtration and stirring ensures that the gas and liquid are mixed evenly and the medium is pure, providing a high-quality mixed medium for subsequent injection.
[0034] Reference Figures 2-4Multiple sets of retaining rings 55 are provided, and these sets of retaining rings 55 are equidistantly distributed along the length of the fixed rod 52. The nozzle control assembly 2 includes a nozzle 21 with a tapered outlet end and a taper of 15°. The inner wall of the tapered end is finely ground to guide the medium to diffuse evenly along the tapered surface. The top of the nozzle 21 has a hexagonal mesh. Compared with circular mesh, the hexagonal structure can improve structural stability with the same opening area, and the mesh distribution is more uniform, ensuring a consistent flow rate when the medium passes through. A first spray net 22 is fixedly connected to the outer wall of the first spray net 22 with an inner diameter that is exactly the same as the outer diameter of the first spray net 22. A first connecting plate 24 is fixedly connected to the outer wall of the first ring 23, and a moving block 25 is fixedly connected to the outer wall of the first connecting plate 24. The top of the first spray net 22 has a mesh with the same mesh size as the first spray net 22, which is 0.2mm, to ensure that the spray parameters will not change abruptly due to the difference in mesh size during adjustment. The second spray net 28 improves the precision of adjustment. A connecting block 27 is fixedly connected to the outer wall of the second spray net 28. A second ring 26 is fixedly connected to the outer wall of the connecting block 27. A second connecting plate 29 with the same thickness as the first connecting plate 24 (3mm) is fixedly connected to the outer wall of the second ring 26 to ensure that the friction force experienced by the two is the same when sliding, which facilitates synchronous or independent control of the moving speed. A second moving block 210 is fixedly connected to the outer wall of the second connecting plate 29. The top of the nozzle 21 is fixedly connected to the bottom of the injector 1. The outer walls of the first ring 23 and the second ring 26 are rotatably connected to the inside of the bottom end of the injector 1. Lithium-based grease is provided between the first ring 23, the second ring 26 and the inner wall of the bottom end of the injector 1. The outer walls of the second connecting plate 29 and the first connecting plate 24 are slidably connected to the inside of the bottom end of the injector 1. The mixed medium enters the nozzle control assembly 2 at the bottom of the injector 1 and achieves basic spraying through the nozzle 21. This can be achieved by controlling the positions of the first spray net 22 and the second spray net 28: the first spray net 22 is connected to the first connecting plate 24 via the first ring 23 on its outer wall, and the moving block 25 on the outer wall of the first connecting plate 24 can slide inside the bottom of the injector 1, driving the first spray net 22 to move axially or radially along the nozzle 21; similarly, the second spray net 28 is aligned with the first spray net 22, realizing the position adjustment of the second spray net 28. By changing the relative distance and coverage area of the first spray net 22 and the second spray net 28, the spray orifice diameter, medium flow rate and spray range of the nozzle 21 can be precisely controlled, ultimately achieving spraying operation with precise control and efficient delivery.
[0035] Working principle: During use, the flow of the medium drives the rotating blade 54 on the outer wall of the ring 53 in the mixing component 5 to rotate. The ring 53 is rotatably connected to the retaining ring 55 on the outer wall of the fixed rod 52, and can rotate stably around the fixed rod 52. The rotation of the rotating blade 54 can actively stir the gas and liquid. At the same time, the medium needs to pass through the top filter screen 51 and the bottom filter screen 56 in sequence. The filter screen 51 can filter impurities in the initially entering medium, and the bottom filter screen 56 further refines the medium particles and filters residual impurities after stirring. The combination of dual filtration and stirring ensures that the gas and liquid are mixed evenly and the medium is pure, providing a high-quality mixed medium for subsequent spraying. The mixed medium enters the nozzle control component 2 at the bottom of the injector 1, and the basic spraying is achieved through the nozzle 21. This can be achieved by controlling the positions of the first spray net 22 and the second spray net 28: the first spray net 22 is connected to the first connecting plate 24 via the first ring 23 on its outer wall, and the moving block 25 on the outer wall of the first connecting plate 24 can slide inside the bottom of the injector 1, driving the first spray net 22 to move axially or radially along the nozzle 21; similarly, the second spray net 28 is aligned with the first spray net 22, realizing the position adjustment of the second spray net 28. By changing the relative distance and coverage area of the first spray net 22 and the second spray net 28, the spray orifice diameter, medium flow rate and spray range of the nozzle 21 can be precisely controlled, ultimately achieving spraying operation with precise control and efficient delivery.
