DETAILED DESCRIPTION

[0020] The present application provides a bubble generating device, which improves the efficiency of disassembly and replacement of the components of the bubble generating device. The present application also provides a gas-liquid mixing device including the bubble generating device.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] like Figure 1 and Figure 2 As shown, the bubble generating device provided by the present application includes a bubble generating assembly 1, a supporting assembly 2 and a fastener 3. The bubble generating assembly 1 includes a gas delivery pipeline 11, a first connecting member 12 and a nozzle assembly 13. The gas delivery pipeline 11 is fixedly connected to the first connecting member 12. When the first connecting member 12 is moved, the gas delivery pipeline 11 can be moved at the same time, which is convenient for the overall replacement of the gas delivery pipeline 11 and the nozzle assembly 13 that are in contact with the liquid for a long time. The nozzle assembly 13 includes a nozzle 131, a connecting pipe 133 and a base 134. The nozzle 131 is detachably connected to the connecting pipe 133, the connecting pipe 133 is fixedly connected to the base 134, and the base 134 is fixedly connected to the gas delivery pipeline 11. The nozzle assembly 13 can be moved and taken out together with the gas delivery pipeline 11, and the nozzle 131 can be removed and replaced separately from the connecting pipe 133. When only the nozzle 131 has problems such as corrosion or blockage, replacement or cleaning is faster and more convenient. The support assembly 2 includes a second connector 21 and a support pipe 22, the second connector 21 is fixedly connected to the support pipe 22, and the support pipe 22 is connected to the liquid pipe 4. The fastener 3 connects the first connector 12 and the second connector 21, the inner diameter of the support pipe 22 is larger than the outer diameter of the gas delivery pipe 11, the gas delivery pipe 11 passes through the inside of the support pipe 22, and the nozzle 131 is set in the liquid pipe 4, and the pipe port where the gas delivery pipe 11 enters the liquid pipe 4 is sealed. Specifically, the pipe port where the gas delivery pipe 11 enters the liquid pipe 4 is sealed by a plugging plate. The sealed port of the gas delivery pipe 11 allows all the gas to be discharged from the nozzle 131 at a suitable amount and speed, so as to achieve the purpose of fully mixing the gas and liquid.

[0023] In a specific embodiment of the present application, the first connecting member 12 is a flange cover, and the second connecting member 21 is a flange. The flange cover can be tightly connected to the flange through a fastener 3 to prevent gas from entering the liquid pipeline 4, and at the same time, the gas delivery pipeline 11 can be stably connected to the support assembly 2.

[0024] In a specific embodiment of the present application, the air inlet end of the nozzle 131 is fixedly connected to the nozzle nut 132, and the connecting pipe 133 is not fixedly connected to the base end and is provided with a thread that matches the nozzle nut 132. In this way, by using an appropriate tool or method, such as using a rotating and tightening tool, etc., the nozzle 131 and the nozzle nut 132 fixedly connected thereto can be easily removed and a new nozzle 131 can be replaced.

[0025] In a specific embodiment of the present application, a shock-absorbing component 121 is further provided on the contact surface where the first connecting member 12 is connected to the second connecting member 21. The shock-absorbing component 121 is arranged around the gas delivery pipe 11 and supports the gas delivery pipe 11. Since one end of the gas delivery pipe 11 is arranged in the liquid flow of the liquid pipe, the flow impact of the liquid will cause the gas delivery pipe 11 to vibrate, thereby increasing wear and reducing the service life. In this embodiment, the shock-absorbing component 121 can relieve the vibration of the gas delivery pipe 11. Specifically, the shock-absorbing component 121 can be a rib plate, and the number of rib plates can be one or more. Preferably, the number of rib plates can be 3 or 4. The rib plates are arranged around the gas delivery pipe 11 so as to reduce vibration from multiple directions.

[0026] In a specific embodiment of the present application, the fastener 3 is a bolt and a nut. Using a bolt and a nut as the fastener 3 can be disassembled by using common rotating and tightening tools, and the operation is simple, convenient and fast.

[0027] Based on the bubble generating device provided in the above embodiments, the present application further provides a gas-liquid mixing device, including the bubble generating device of any one of the above embodiments.

[0028] During actual operation, when the nozzle 131 needs to be replaced, first, it is necessary to determine the outlet size of the nozzle 131 to be replaced by observing the liquid flow data in the liquid pipe 4. Using an appropriate tool or method, the connection between the first connecting member 12 and the second connecting member 21 is released by rotating the bolt and nut of the fastener 3. Once the connection is released, the first connecting member 12 and the gas delivery pipe 11 can be removed as a whole, and then using an appropriate tool or method, the nozzle 131 to be replaced and its nozzle nut 132 at the lower end of the gas delivery pipe 11 are disconnected from the connecting pipe 133. After removing the nozzle 131 and its nut 132, the new nozzle 131 and its nut 132 are carefully tightened onto the connecting pipe 133 and ensure good connection. After replacing the nozzle 131, the first connecting member 12 and the second connecting member 21 are re-fastened and connected by rotating the bolt and nut of the fastener 3, and then tests and verifications are carried out to ensure that the replaced new components are correctly installed and working properly. For example, functional tests are performed on the equipment, the bubble generation effect is observed, or performance indicators are monitored, etc. Similarly, when the gas delivery pipe 11 needs to be replaced, the above similar operations are also carried out, and it is decided whether to replace it together according to the situation of the nozzle 131, which will not be elaborated here.

[0029] Since the gas-liquid mixing device adopts the bubble generating device of the above embodiment, the beneficial effects brought by the bubble generating device to the gas-liquid mixing device can be referred to the above embodiment.
