Description

Technical Field

[0001] This utility model relates to the field of jet technology, specifically to a jet ejector. Background Technology

[0002] Ejectors are primarily used in gas dosing systems and water treatment, achieving gas delivery and reagent dosing by generating a vacuum and mixed solution. Their core applications include chlorination systems and wastewater treatment. Operating on the Venturi principle, their main structure consists of a nozzle, suction chamber, and diffuser, and materials include PVC, stainless steel, and plexiglass.

[0003] Existing ejectors directly connect the pipeline for adding the agent (such as liquid cobalt) to a pipeline of high-pressure air, using the negative pressure generated by the high-pressure air to draw in and disperse the liquid cobalt. In practical use, the applicant has found that this direct-connection structure is prone to problems such as poor liquid cobalt input or backflow of high-pressure gas into the liquid cobalt input pipeline. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an ejector to solve the technical problem of poor cobalt liquid input caused by the direct connection structure in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides an ejector, including an ejector tube, which has a gas flow channel and a buffer chamber. The buffer chamber is connected to the gas flow channel through a connecting port. The ejector tube has an air inlet and an air outlet that connect to the gas flow channel, and a liquid outlet that connects to the buffer chamber. The liquid outlet and the connecting port are located on both sides of the gas flow channel, respectively.

[0006] In some embodiments, the gas flow channel is arranged along the length of the jet tube, and the air inlet and the air outlet are located at both ends of the jet tube.

[0007] In some embodiments, the buffer chamber is arranged around the gas flow channel, and the connection port connects to the bottom of the buffer chamber.

[0008] In some embodiments, the gas flow channel includes an inlet section, an intermediate section, and an outlet section connected in sequence. Along the direction of gas movement, the inner diameter of the inlet section gradually decreases, and the inner diameter of the outlet section gradually increases.

[0009] In some embodiments, the connection port connects to the intermediate section and is located near the air intake section.

[0010] In some embodiments, an air intake connector is further included, which is detachably connected to the air intake port. The air intake connector has an air intake pipe communicating with the gas flow channel, and one end of the air intake pipe communicating with the gas flow channel is formed with a flared structure with a gradually expanding inner diameter.

[0011] In some embodiments, the system further includes an exhaust connector, which is detachably connected to the exhaust port. The exhaust connector has an exhaust pipe communicating with the gas flow channel, and one end of the exhaust pipe communicating with the gas flow channel has a flared structure with a gradually decreasing inner diameter.

[0012] In some embodiments, a liquid connector is further included, which is detachably connected to the liquid port and has a liquid conduit communicating with the buffer chamber.

[0013] In some embodiments, the air inlet, air outlet, and liquid inlet are detachably connected to the jet pipe via threads or flanges.

[0014] In some embodiments, the jet tube is transparent.

[0015] Compared with the prior art, the jet ejector provided by this utility model has a buffer chamber. The liquid inlet is connected to the gas flow channel through the buffer chamber, and the connecting port is arranged on the other side away from the liquid inlet. This allows the high-pressure gas that is backflushing to collide and contact with the cobalt liquid in the buffer chamber, dissipating the kinetic energy and effectively protecting the cobalt liquid input pipe. This not only avoids the problem of poor cobalt liquid input, but also avoids the problem of leakage of the cobalt liquid input pipe caused by backflushing vibration. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem of poor cobalt liquid input caused by the direct connection structure of existing jet injectors, this invention provides a jet injector that buffers the backflow of high-pressure airflow by setting up a buffer chamber.

[0019] It should be noted that the jet ejector described in this utility model is used for, but not limited to, high-pressure air blowing to disperse cobalt liquid. For ease of explanation, this utility model only uses the application of the jet ejector to high-pressure air blowing to disperse cobalt liquid as an example. The principle of the jet ejector in other scenarios is essentially the same as that in high-pressure air blowing to disperse cobalt liquid, and will not be described in detail here.

[0020] Please see Figure 1 , Figure 1 This is a cross-sectional view of the jet ejector provided in an embodiment of the present invention. The jet ejector includes a jet pipe 1, which has a gas flow channel 11 and a buffer chamber 12. The buffer chamber 12 is connected to the gas flow channel 11 through a connecting port 13. The jet pipe 1 has an air inlet and an air outlet connecting to the gas flow channel 11, and a liquid outlet connecting to the buffer chamber 12. The liquid outlet and the connecting port 13 are located on both sides of the gas flow channel 11, respectively.

[0021] The ejector provided by this utility model features a buffer chamber 12, through which the liquid inlet is connected to the gas flow channel 11, and the connecting port 13 is located on the side away from the liquid inlet. The high-pressure gas from the backflow collides and contacts the cobalt liquid within the buffer chamber 12, dissipating its kinetic energy. This not only avoids the problem of poor cobalt liquid input but also prevents leakage from the cobalt liquid input pipe caused by backflow vibration.

[0022] In some embodiments, the gas flow channel 11 is arranged along the length of the jet pipe 1, with the inlet and outlet located at both ends of the jet pipe. Preferably, the inlet is located at the upper end of the jet pipe 1, and the outlet is located at the lower end of the jet pipe 1.

[0023] Based on the above embodiment, the buffer chamber 12 is arranged around the gas flow channel 11, and the connecting port 13 connects to the bottom of the buffer chamber 12. This surrounding arrangement further enhances the buffering effect of the buffer chamber 12 on the backflow high-pressure gas, allowing the high-pressure gas to more fully collide and contact with the cobalt liquid within the buffer chamber 12, and more effectively dissipating kinetic energy. At the same time, this arrangement also makes the entire ejector structure more compact and improves space utilization.

[0024] In some embodiments, the gas flow channel 11 includes an inlet section 111, an intermediate section 112, and an outlet section 113 connected in sequence. Along the direction of gas movement, the inner diameter of the inlet section 111 gradually decreases, while the inner diameter of the outlet section 112 gradually increases. This structural design allows the gas to accelerate in the inlet section 111 and decelerate in the outlet section 113, which is beneficial for the stable flow of gas within the ejector and also enhances the ejector's ability to control the gas.

[0025] Based on the above embodiment, the connecting port connects to the middle section 112 and is close to the air inlet section 111. This arrangement allows the cobalt liquid entering the gas flow channel 11 from the buffer chamber 12 to mix more smoothly with the gas, thus improving the mixing effect.

[0026] In some embodiments, the jet injector further includes an air inlet connector 2, which is detachably connected to an air inlet. The air inlet connector 2 has an air inlet pipe 21 communicating with a gas flow channel 11. One end of the air inlet pipe 21 communicating with the gas flow channel 11 has a flared structure with a gradually expanding inner diameter. This structure facilitates the smooth entry of gas and reduces the resistance when the gas enters.

[0027] In some embodiments, the jet ejector further includes an outlet connector 3, which is detachably connected to an outlet. The outlet connector 3 has an outlet pipe 31 communicating with the gas flow channel 11. One end of the outlet pipe 31 communicating with the gas flow channel 11 forms a trumpet-shaped structure with a gradually decreasing inner diameter. This structure facilitates the smooth discharge of gas and also plays a certain role in rectifying the gas flow.

[0028] Preferably, the inner diameter of the exhaust pipe 31 is larger than the inner diameter of the intake pipe 21.

[0029] In some embodiments, the jet injector further includes a liquid connector 4, which is detachably connected to a liquid inlet. The liquid connector 4 has a liquid pipe 41 communicating with the buffer chamber 12. The air inlet connector 2, air outlet connector 3, and liquid connector 4 allow for convenient and quick connection to other equipment, such as air supply equipment, liquid supply equipment, and receiving equipment.

[0030] In some embodiments, the air inlet connector 2, air outlet connector 3, and liquid connector 4 are detachably connected to the jet pipe 1, facilitating the replacement of connectors of different specifications or types according to actual needs, thus enhancing the versatility and flexibility of the equipment. In this embodiment, the connection method adopts either threaded or flanged connection. Threaded connection is suitable for small equipment in laboratories where the overall load is not large, and the threaded connection can withstand it, while also being more convenient to assemble and disassemble. Flange connection is suitable for large equipment in industrial production, providing a more stable connection and being able to withstand greater pressure and vibration.

[0031] In some embodiments, the jet tube 1 is made of a transparent material, such as plexiglass. This design allows operators to visually observe the gas and liquid flow inside the jet injector, facilitating timely detection and handling of potential problems, such as cobalt liquid blockage or gas leakage. Simultaneously, the transparent material also facilitates monitoring and adjustment of the jet injector's operating status, improving the maintainability and ease of use of the equipment.

[0032] Compared with existing technologies, the ejector provided by this utility model, by setting a buffer chamber 12, connects the liquid inlet to the gas channel 11 through the buffer chamber 12, and the connecting port 13 is located on the other side away from the liquid inlet. This effectively avoids the problem of poor cobalt liquid input caused by direct impact of high-pressure gas. Simultaneously, the design of the buffer chamber 12 surrounding the gas channel 11 allows the liquid to be fully dispersed before entering the gas channel 11, further improving the mixing effect. In the gas channel 11, the design of the gradually decreasing inner diameter of the inlet section 111 and the gradually increasing inner diameter of the outlet section 113 helps to form a stable airflow, enhancing the ejector's suction capacity. Furthermore, the detachable connection design of the inlet connector 2, outlet connector 3, and liquid connector 4 not only facilitates the installation and maintenance of the equipment but also improves its versatility and flexibility. The transparent nature of the ejector tube allows operators to observe the internal fluid flow status in real time, enabling timely detection and resolution of problems.

[0033] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
