Description

Technical Field

[0001] This utility model relates to the field of jet generator technology, specifically a multi-functional jetting device for a jet generator. Background Technology

[0002] Ejectors are commonly used equipment in wastewater treatment in environmental engineering, serving as oxygenation devices in aerobic biological wastewater treatment.

[0003] According to a publicized gas-liquid mixing jet injection device (publication number: CN222428285U), the aforementioned application includes a mounting box, a mounting frame, a dustproof net, a side plate, an elastic telescopic rod, and a locking block. During installation, the dustproof net is installed onto the mounting frame, then the locking block is moved upwards, the elastic telescopic rod shortens, and the mounting frame slides into the mounting box. Finally, the locking block is released, the elastic telescopic rod extends, and the locking block moves downwards to the side of the side plate, blocking the side plate. When air is drawn in, it must first pass through the dustproof net, thereby filtering the drawn-in air and preventing the intake of impurities.

[0004] However, in actual use, the water pressure of the jet nozzle is relatively low, and the mixing efficiency of the air and water when the air is sucked into the nozzle is poor, resulting in limited pressure increase within the jet nozzle. Therefore, we propose a multi-functional jetting device for jet units. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional jetting device for a jet generator set to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional jetting device for a jet generator, comprising a nozzle, wherein a pressurizing component is disposed inside the nozzle, the pressurizing component comprising:

[0007] An air inlet is fixedly installed on the top outer surface of the nozzle. An installation sleeve is fixedly installed on the top inner wall of the air inlet. A T-shaped post is slidably installed on the inner wall of the installation sleeve. A return spring is fixedly connected between the top lower surface of the T-shaped post and the bottom inner wall of the installation sleeve. A baffle is fixedly installed at the bottom end of the T-shaped post.

[0008] A spiral flow channel is formed on the arc-shaped inner wall of the nozzle. A narrow flow channel is provided on the arc-shaped inner surface at the center of the nozzle, and a reduced diameter orifice is provided on the inner wall of the end of the nozzle away from the air inlet.

[0009] Preferably, an air inlet is provided on the top inner wall of the air inlet, and the air inlet is located on the outside of the mounting sleeve. The air inlet is located above the baffle, so that the baffle can block the air inlet in the initial state.

[0010] Preferably, the outer diameter of the baffle is smaller than the inner diameter of the air inlet. Under atmospheric pressure, the external air will exert downward pressure on the baffle, so that the baffle is exposed at the air inlet, and the external air will enter the internal cavity of the nozzle through the air inlet.

[0011] Preferably, the spiral flow channel is spirally arranged, and the cross-section of the spiral flow channel is arc-shaped. The spiral flow channel is arranged to fit the internal cavity of the nozzle and the arc-shaped inner surface of the narrow flow channel, and the air inlet is arranged at the gap of the spiral flow channel.

[0012] Preferably, the narrow flow channel is located at the center of the nozzle, and the narrow flow channel is wide at both ends and narrow in the center, thereby forming a pressurized section in the internal cavity at the center of the nozzle.

[0013] Preferably, a protrusion is fixedly installed on the arc-shaped inner surface of the spiral flow channel.

[0014] Preferably, the number of protrusions is set in multiple groups, and the multiple groups of protrusions are evenly distributed at equal distances inside the spiral flow channel, so as to divert and disperse the water flow entering the spiral flow channel.

[0015] Compared with the prior art, this utility model provides a multi-functional jetting device for a jet generator set, which has the following beneficial effects:

[0016] 1. The multi-functional jetting device of this jetting unit is equipped with a spiral flow channel, which allows the air drawn into the air inlet to mix with the spiral water flow inside the nozzle. Combined with the pressurization of the narrow flow channel, it promotes better mixing of water and air, thereby accelerating the expansion of air in the water flow, so as to better pressurize the cavity inside the nozzle and improve the jetting force and jetting effect of the nozzle.

[0017] 2. The multi-functional jetting device of this jetting unit has several protrusions in the spiral channel to divert and disperse the water flow entering the spiral channel, so as to promote better mixing of water and air and generate an expansion and pressurization effect in the water flow.

[0022] like Figures 1-3 As shown, this utility model provides a technical solution: a multi-functional jetting device for a jetting unit, including a nozzle 1, and a pressurizing component 2 is provided inside the nozzle 1. The pressurizing component 2 includes an air inlet 21, a mounting sleeve 211, a T-shaped column 212, a return spring 214, a baffle 213, a spiral flow channel 22, a protrusion 221, a narrow flow channel 23, and a reduced diameter port 24.

[0023] In one embodiment of this utility model, the air inlet 21 is fixedly installed on the top outer surface of the nozzle 1, and an installation sleeve 211 is fixedly installed on the top inner wall of the air inlet 21. A T-shaped post 212 is slidably installed on the inner wall of the installation sleeve 211. A return spring 214 is fixedly connected between the top lower surface of the T-shaped post 212 and the bottom inner wall of the installation sleeve 211. A baffle 213 is fixedly installed at the bottom end of the T-shaped post 212. A spiral flow channel 22 is opened on the arc-shaped inner wall of the nozzle 1. A protrusion 221 is fixedly installed on the arc-shaped inner surface of the spiral flow channel 22. A narrow flow channel 23 is provided on the arc-shaped inner surface at the center of the nozzle 1. A reduced diameter orifice 24 is provided on the inner wall of the end of the nozzle 1 away from the air inlet 21.

[0024] Furthermore, the inner wall of nozzle 1 is hollow, and a connecting sleeve is provided at the end of nozzle 1 near air inlet 21 to facilitate the installation of nozzle 1 on the output end of jet generator. This allows the central cavity of nozzle 1 to spray water out under the pressure of jet generator to form a jet. At the same time, an air inlet is provided on the top inner wall of air inlet 21, and the air inlet is located outside the mounting sleeve 211. The air inlet is located above baffle 213, so that in the initial state, baffle 213 can block the air inlet. The outer diameter of baffle 213 is smaller than the inner diameter of air inlet 21. Therefore, when the water inside nozzle 1 is affected by high pressure and flows rapidly, due to the Venturi effect, the pressure on the side near the central cavity of nozzle 1 is smaller. Under the action of atmospheric pressure, the external air will exert downward pressure on baffle 213, so that baffle 213 is exposed to air inlet, and the external air will enter the internal cavity of nozzle 1 through air inlet 21.

[0025] Furthermore, the spiral flow channel 22 is spirally arranged, and its cross-section is arc-shaped. The spiral flow channel 22 fits the internal cavity of the nozzle 1 and the arc-shaped inner surface of the narrow flow channel 23. Additionally, the air inlet 21 is positioned at the gap in the spiral flow channel 22 to ensure the overall continuity of the spiral flow channel 22 within the nozzle 1. This allows the water flow to form a spiral-like trend within the nozzle 1 when passing through the internal cavity of the nozzle 1 equipped with the spiral flow channel 22. This better draws the air inhaled by the air inlet 21 into the water flow, creating a mixing effect. Simultaneously, multiple sets of protrusions 221 are evenly distributed at equal intervals within the spiral flow channel 22 to divert and disperse the water flow entering the spiral flow channel 22, promoting better mixing of the water and air. This accelerates the expansion of air in the water flow, better pressurizing the internal cavity of the nozzle 1 and enhancing the spray force and effect of the nozzle 1.

[0026] In an embodiment of this utility model, the narrow flow channel 23 is disposed at the center of the nozzle 1, and the narrow flow channel 23 is wide at both ends and narrow in the center, thereby forming a pressurized section in the internal cavity at the center of the nozzle 1, which further pressurizes the water flow after it has been mixed with the gas through the spiral flow channel 22, thereby increasing the spray intensity of the nozzle 1.

[0027] Specifically, the reduced diameter orifice 24 is arranged such that the inner diameter gradually decreases near the end of the nozzle 1, thereby reducing the size of the spray nozzle at the outlet of the nozzle 1, thereby reducing the effective range of the sprayed water flow of the nozzle 1 and increasing the impact intensity of the sprayed water flow of the nozzle 1.

[0028] In this invention, during use, the end of the nozzle 1 near the air inlet 21 is connected to the output end of the jet generator. When jetting is required, the jet generator is started to input high-pressure water into the nozzle 1. Through the flow of high-pressure water, the pressure in the internal cavity of the nozzle 1 is reduced. Under the action of atmospheric pressure, the baffle 213 is pressed downward, so that the baffle 213 is exposed at the air inlet. External air will enter the internal cavity of the nozzle 1 through the air inlet 21. When the water flows through the internal cavity of the nozzle 1 equipped with the spiral flow channel 22, it can form a spiral water flow inside the nozzle 1, thereby better entraining the air drawn in from the air inlet 21 into the water flow, so as to produce a mixing effect in the water flow, thereby accelerating the expansion of air in the water flow, so as to better pressurize the internal cavity of the nozzle 1 and improve the jetting force and jetting effect of the nozzle 1.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
