Description

Technical Field

[0001] The utility model relates to the technical field related to bubble generators, in particular to a gas volume detection device for a nano bubble generator. Background Art

[0002] The charged micron bubbles produced by the nano bubble generator have a negative charge on their surface, and compared with ordinary bubbles, they have a higher negative charge. Generally, the surface load of bubbles below 30um is about -40mV, which is one of the reasons why micron bubbles can gather together in large quantities for a long time without breaking. The negative charge of micron bubbles can be used to adsorb positively charged substances in the water, which has a good effect on the adsorption and separation of suspended matter or pollutants in the water. A gas-liquid mixing device is often used in a micro-nano bubble generator. The main function of the gas-liquid mixing device is to fully mix the gas and liquid. The common gas-liquid mixing device is to input gas into the liquid and stir it to achieve full mixing of the gas and liquid.

[0003] Existing micro-nano bubble generators have the following deficiencies when in use: lack of detection of the gas volume in the output bubble flow. In some applications, especially when precise control of the amount of bubble generation is required, this defect may cause the system to be unable to meet specific process requirements; at the same time, due to the lack of gas volume monitoring means, it is difficult for traditional systems to achieve precise regulation of the amount of bubble generation, which is not desirable in some experiments or production processes that require highly precise control; due to the inability to accurately monitor the amount of bubble generation, traditional systems may waste water and gas resources, resulting in unnecessary costs and waste of resources.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The gas volume detection device of the nano bubble generator provided by the utility model comprises a shell 1, a water pump 2, an air pump 3, a mixing chamber 4, a detection mechanism, and a control box 5 arranged inside the shell 1. An air inlet pipe 6, a water inlet pipe 7, and a release pipe 8 are arranged on the shell 1. The air inlet pipe 6 and the water inlet pipe 7 are respectively connected to the air inlet end of the air pump 3 and the water inlet end of the water pump 2. The water outlet end of the water pump 2 and the air outlet end of the air pump 3 are extended to the interior of the mixing chamber 4. One end of the release pipe 8 is connected to the upper end of the mixing chamber 4. The detection mechanism is composed of a branch pipe 9, a gas-liquid separator 10, an exhaust pipe 11, a drain pipe 12, a first electromagnetic flowmeter 13, and a second electromagnetic flowmeter 14. The first electromagnetic flowmeter 13 and the second electromagnetic flowmeter 14 are electrically connected to the control box 5.

[0019] The gas-liquid separator 10 is connected to the release pipe 8 through the branch pipe 9. The drain pipe 12 and the exhaust pipe 11 are respectively connected to the drain port and the exhaust port of the gas-liquid separator 10. The first electromagnetic flowmeter 13 and the second electromagnetic flowmeter 14 are respectively arranged on the branch pipe 9 and the exhaust pipe 11.

[0020] The branch pipe 9 is provided with a solenoid valve 15 electrically connected to the control box 5 at one end close to the release pipe 8 .

[0021] One end of the drain pipe 12 away from the gas-liquid separator 10 is communicated with the water inlet pipe 7 .

[0022] An air chamber 17 and a mixing chamber 18 are provided inside the mixing chamber 4 through a partition 16 . The water outlet of the water pump 2 extends to the inside of the mixing chamber 18 , and the air outlet of the air pump 3 extends to the air chamber 17 .

[0023] A hollow rotating shaft 19 and a plurality of conveying pipes 20 are arranged inside the mixing chamber 18. The upper end of the hollow rotating shaft 19 passes through the partition 16 and is connected to the output shaft of a motor 21 arranged outside the shell 1. The upper end of the hollow rotating shaft 19 is connected to the air chamber 17 through a through hole 22. An air passage connected to the hollow rotating shaft 19 is arranged inside the conveying pipe 20.

[0024] It can be understood that the motor 21, the air pump 3 and the water pump 2 are all electrically connected to the control box 5 via wires.

[0025] Specifically, when the utility model is used, the motor 21, the water pump 2, and the air pump 3 are started through the control box 5. The motor 21 works, and the delivery pipe 20 and the nozzle at the end are driven to rotate synchronously through the hollow shaft 19. The water pump 2 pumps water into the mixing chamber 18 of the mixing bin 4, and the air pump 3 pumps gas into the air chamber 17 of the mixing bin 4, and enters the interior of the hollow shaft 19 through the through hole 22, and is subsequently sprayed out from the nozzle 23 through the airway to form bubbles, which are finally discharged through the release pipe 8.

[0026] In the above process, the solenoid valve 15 is opened through the control box 5, so that part of the bubbles enter the gas-liquid separator 10 through the branch pipe 9, and form air flow and water flow, which are discharged through the exhaust pipe 11 and the drain pipe 12 respectively. At the same time, the first electromagnetic flowmeter 13 and the second electromagnetic flowmeter 14 monitor the flow of the branch pipe 9 and the exhaust pipe 11 respectively. The effective monitoring of the gas volume in the release pipe 8 is achieved through the monitoring data, which helps to ensure the precise control and adjustment of the bubble generation amount in the application. Compared with the existing method, it can significantly improve the detection accuracy.
