Description

Technical Field

[0001] This utility model relates to the field of jet ejector technology, and in particular to a gas-liquid mixing jet ejector. Background Technology

[0002] Ejectors are commonly used equipment in wastewater treatment in environmental engineering. They are used as oxygenation devices or as chemical mixing devices in aerobic biological wastewater treatment.

[0003] A search revealed that existing technology CN203886438U describes a gas-liquid mixing jet, mainly composed of a gas nozzle, a liquid nozzle, and an inner liquid nozzle. After entering the liquid pipe, the liquid splits into two paths. One path begins at the liquid inlet and ends at the liquid nozzle. The other path originates at the inner liquid pipe and terminates at the inner liquid nozzle. Both the liquid nozzle and the inner liquid nozzle have a tapered, narrower diameter. The inner liquid nozzle is installed inside the gas nozzle, and the liquid nozzle, gas nozzle, and inner liquid nozzle are concentric. Gas is drawn into the pipe through the gas inlet and ejected from the gas nozzle, mixing with the two liquid paths in the mixing zone. This invention, by adding an inner liquid nozzle, provides a larger contact area between the gas and liquid phases, resulting in more efficient mass transfer between the gas and liquid.

[0004] However, the above-mentioned equipment has the following problems in actual use: In the structure of this gas-liquid mixing jet, the gas enters directly from the gas inlet of the gas nozzle and is finally ejected from the gas outlet. However, this structure makes it difficult to adjust the gas-water mixing ratio, which is inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a gas-liquid mixing jet device, which aims to solve the problem that existing gas-liquid mixing jet devices are difficult to adjust the gas-liquid mixing ratio and are inconvenient to use.

[0006] To achieve the above objectives, this utility model provides a gas-liquid mixing jet device, including a connecting pipe, a jet nozzle installed on one side of the connecting pipe, and the water outlet end of the jet nozzle inside the connecting pipe is a conical part;

[0007] It also includes adjustment mechanisms;

[0008] The adjustment mechanism includes a fixed base, a support base, a vent pipe, a support plate, an adjusting screw, a mating mandrel, and an installation device. The fixed base is installed on the air inlet side of the connecting pipe via the installation device. The support base is detachably installed on the fixed base. The vent pipe is detachably installed on the top of a single air outlet inside the support base. The vent pipe has multiple vent holes arranged in a ring and at intervals. The support plate is detachably installed on the top of the support base and has an air inlet pipe. The adjusting screw is threaded to the support plate and passes through it. The mating mandrel is integrally formed with the adjusting screw and slidably connected to the vent pipe.

[0009] The water inlet pipe on the jet nozzle is connected to an external water supply pipe.

[0010] The installation device includes a fixing plate and a mating component. The fixing plate is detachably connected to the connecting pipe and is located on the air inlet side of the connecting pipe. The mating component is disposed on one side of the fixing plate.

[0011] The mating components include an inclined tube and a ball valve, with the inclined tube welded to the fixed plate; the ball valve is detachably connected to both the flange on the inclined tube and the flange on the fixed seat.

[0012] The gas-liquid mixing jet further includes a protective mechanism, which includes a base and a protective sleeve. The base is detachably connected to the support plate and is located outside the adjusting screw. The protective sleeve is threadedly connected to the base and is located outside the adjusting screw.

[0013] This utility model discloses a gas-liquid mixing jet injector. When in use, an external water pump is powered on, allowing water to flow through the jet nozzle into the connecting pipe. As the cross-sectional area of ​​the jet nozzle gradually decreases near the conical part, the water flow velocity increases, creating a vacuum zone between the conical part and the inner wall of the connecting pipe. This facilitates the entry of external air into the connecting pipe, allowing ozone or other gases to mix with the water. The depth of the fit between the mandrel and the vent pipe is adjusted by rotating the adjusting screw, thereby increasing or decreasing the number of vent holes for ventilation and regulating the air intake. This adjusts the gas-liquid mixing ratio, solving the problem of existing gas-liquid mixing jet injectors being difficult to adjust and inconvenient to use. Attached Figure Description

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of the gas-liquid mixing jet. Figure 2 This is a cross-sectional view of the connecting pipe 101. Figure 3 This is a schematic diagram of the structure of the vent tube 106. Figure 4 This is a schematic diagram of the structure of the mandrel 109. This utility model provides a gas-liquid mixing jet injector: including a connecting pipe 101, a jet nozzle 102, a conical part 103, and an adjusting mechanism. The adjusting mechanism includes a fixed base 104, a support base 105, a vent pipe 106, a support plate 107, an adjusting screw 108, a mandrel 109, and an installation device.

The aforementioned solution solves the problem of existing gas-liquid mixing jet injectors being difficult to adjust the gas-liquid mixing ratio and inconvenient to use. It is understood that the aforementioned solution can adjust the gas-liquid mixing ratio.

[0025] In this embodiment, an air inlet is provided on the middle side of the top of the connecting pipe 101.

[0026] The fixed base 104 is installed on the air inlet side of the connecting pipe 101 via the mounting device. The support base 105 is detachably installed on the fixed base 104. The vent pipe 106 is detachably installed on the top of a single air outlet inside the support base 105. The vent pipe 106 has a plurality of vent holes 110 arranged in a ring and at intervals. The support plate 107 is detachably installed on the top of the support base 105 and is provided with an air inlet pipe 111. The adjusting screw 108 is threadedly connected to the support plate 107 and passes through it. The mating mandrel 109 is integrally formed with the adjusting screw 108 and is slidably connected to the vent pipe 106. The fixed base 104 has a T-shaped structure. The flange is connected to the air inlet flange of the ball valve 114 by a screw and nut. The fixed plate of the support base 105 is connected to the fixed base 104 by bolts. The top of the support base 105 is fixed to the support plate 107 by bolts. The support plate 107 is provided with an air inlet pipe 111 for air intake. The support plate 107 is provided with a through threaded hole to facilitate the setting of the adjusting screw 108. The adjusting screw 108 has an external hexagonal end for easy adjustment by wrench rotation. The adjusting screw 108 is integrally provided with the mating mandrel 109. The mating mandrel 109 has the same internal cavity size as the vent pipe 106, which facilitates sliding installation and rotational adjustment. The vent pipe 106 is U-shaped and fixed by bolts. The vent pipe 106 is provided with a ring of multiple vent holes 110. The vent holes 110 are also arranged vertically at intervals to form multiple sets of air intake structures that cooperate with the mating mandrel 109. The installation device is used to connect and install the fixed base 104 with the connecting pipe 101 and to enable ventilation after installation.

[0027] Secondly, the inlet pipe on the jet nozzle 102 is connected to an external water supply pipe. This structure facilitates the delivery of water into the jet nozzle 102 when the external water pump is activated.

[0028] Then, the fixing plate 112 is detached from the connecting pipe 101 and located on the air inlet side of the connecting pipe 101; the mating assembly is disposed on one side of the fixing plate 112. The fixing plate 112 is provided with an inclined hole and is fixed by bolts, and a sealing gasket is provided on its contact end face with the connecting pipe 101 for sealing. The mating assembly is used for air passage mating.

[0029] Finally, the inclined pipe 113 is welded to the fixed plate 112; the ball valve 114 is detachably connected to the flange on the inclined pipe 113 and the flange on the fixed seat 104, respectively. A connecting flange is provided on the inclined pipe 113, and the connecting flanges on both sides of the ball valve 114 are connected by screws and nuts, respectively, for cutting off the gas.

[0030] When using this invention to solve the problem of existing gas-liquid mixing jets being difficult to adjust the gas-water mixing ratio and inconvenient to use, the first step is to control the external water pump to be powered on, so that water flows through the jet nozzle 102 into the interior of the connecting pipe 101. As the cross-sectional area of ​​the jet nozzle 102 gradually decreases near the conical part 103, the water flow rate can be increased, creating a vacuum zone between the conical part 103 and the inner wall of the connecting pipe 101. This facilitates the entry of external air into the interior of the connecting pipe 101, thereby facilitating the mixing of external ozone or other gases with the water flow. By rotating the adjusting screw 108 to adjust the mating depth between the mating mandrel 109 and the vent pipe 106, the number of vent holes 110 used for venting can be increased or decreased, thus adjusting the air intake and adjusting the gas-liquid mixing ratio. This solves the problem of existing gas-liquid mixing jets being difficult to adjust the gas-water mixing ratio and inconvenient to use.

[0031] Example 2:

[0032] like Figure 5 and Figure 6 As shown, where Figure 5 This is a schematic diagram of the overall structure of the gas-liquid mixing jet. Figure 6 yes Figure 5 The enlarged view at point A shows that, based on the first embodiment, this utility model provides a gas-liquid mixing jet, which further includes a protective mechanism, comprising a base 201 and a protective sleeve 202.

[0033] The base 201 is detachably connected to the support plate 107 and is located outside the adjusting screw 108. The protective sleeve 202 is threadedly connected to the base 201 and is also located outside the adjusting screw 108. The base 201 is fixed by bolts and has a circular threaded cavity inside, which facilitates the avoidance of the adjusting screw 108 and the installation of the protective sleeve 202. The protective sleeve 202 has a U-shaped cross-section, and its length is greater than the length of the structure formed by the adjusting screw 108 and the mating mandrel 109. The external threaded end directly mates with the threaded cavity on the base 201 for installation.

[0034] In this embodiment, by providing the base 201 and the protective sleeve 202, the exposed threads of the adjusting screw 108 can be protected, and the protective sleeve 202 can be removed directly for subsequent adjustment.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
