Existing bubble generator is mostly venturi type, and the negative pressure of the low-pressure area formed by Venturi tube structure introduces gas Body is passed directly into compressed air, then is discharged into molten gas in fluid in the form of bubble higher-pressure region.The master of this kind design It wants problem to be that the amount of gas inhalation is heavily dependent on the formation of negative pressure, is sent out in fluid Parameters variation itself or flow regime When changing, as fluid temperature and flow velocity variation when, the soakage of gas is difficult to control, and the variation of fluid parameter itself Seriously affect the release of bubble, it is difficult to guarantee stable bubble yield and bubble size.
Correspondingly, needing the nano-bubble generating apparatus that a kind of structure is simple and convenient to operate while frothing percentage is more stable To solve the above problems.
Summary of the invention
The purpose of the present invention is to solve the above problem present in existing bubble generator, the present invention provides one kind The bubble generator controllable, generation bubble is more uniform, fine.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of novel controllable nano bubble fills It sets, including Venturi tube, air inlet pipe, porous disc, pressure sensor, solenoid valve, control circuit, air pump, Venturi tube includes gradually Contracting section, throat, divergent segment and outlet section;Air inlet pipe outlet side is connected with Venturi tube in converging transition, air inlet pipe upper end and electromagnetism Valve is connected with air pump, and pressure sensor is located at throat exit, and control circuit connects solenoid valve and pressure sensor, divergent segment and Outlet section junction is equipped with the porous disc of the radially equidistant distribution of multi-turn, the identical cavitation hole of quantity, porous disc and junction wall Face forms secure fit.The shape in the cavitation hole is the clear opening that tail portion has reamer.The air inflow of the air pump by Control circuit passes through solenoid valve control.The pressure sensor is responsible for detecting the pressure of throat outlet, and signal is fed back to Control circuit.
The medicine have the advantages that 1, bubble generate stabilization, pressure sensor and solenoid valve provided by the invention all with control Circuit processed is connected, the input terminal connection of pressure sensor and control circuit, by the detection to throat's outlet pressure, by pressure Signal feeds back to control circuit;Solenoid valve and the output end of control circuit connect, the open and close control that control circuit passes through solenoid valve Air pump adjusts air inflow in this way, guarantees that the pressure in device is mutually in a stable state;2, bubble size is small, this Invention utilizes converging transition and throat, reduces flow area, and gas-liquid two-phase is made to realize gas-liquid mixed in throat, and gas passes through tracheae Into fluid mass, air pocket gas-liquid mixture is formed in converging transition, violent sky occurs in throat for air pocket gas-liquid mixture Change, is ground into microbubble gas-liquid mixture, subsequent microbubble gas-liquid mixture is crushed again through the cavitation hole of porous disc, shape At nano bubble gas-liquid mixture;3, structure is simple, and nano-bubble generating apparatus provided by the invention, structure is simple, user Just, it can run steadily in the long term, good manufacturability, be easily installed maintenance.
