Description

Technical Field

[0001] The invention relates to the technical field of bubble generation, in particular to a gas self-priming resonance micro-nano bubble generating device. Background Art

[0002] The key to micro-nano bubble technology is how to efficiently generate micro-nano bubbles. The micro-nano bubble generator is the main equipment in the micro-nano bubble manufacturing technology. Its performance directly affects the size, quantity and uniformity of the generated bubbles. There are many methods for making micro-bubbles, such as physical cutting method, pressurized dissolved gas release method, water temperature difference method, electric field method, ultrasonic method, etc. The micro-nano bubble generator based on the physical cutting method mainly shears and breaks the air through a porous filter medium, which can cut and form micro-bubbles with high efficiency.

[0003] The traditional Venturi-type micro-nano bubble generator relies on the negative pressure of the low-pressure zone formed by the Venturi structure to introduce gas or directly introduce compressed air, and then releases the dissolved gas into the fluid in the form of bubbles through the high-pressure zone, and finally breaks the large-sized bubbles through the hydraulic shearing action of the rotating flow field. The main problem with this design is that the amount of gas intake depends largely on the formation of negative pressure. When the parameters of the fluid itself change or the flow state changes, such as changes in liquid temperature and flow rate, the amount of gas intake is difficult to control. The change of the fluid parameters itself also seriously affects the release of bubbles, making it difficult to ensure a stable bubble generation amount and bubble size. Summary of the invention

[0004] The purpose of the present invention is to provide a gas self-absorption resonance micro-nano bubble generating device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention is an air self-priming resonant micro-nano bubble generating device, comprising: a pipeline body, which has a vertical cavity and a first horizontal part and a second horizontal part located on both sides outside the cavity and arranged oppositely, wherein a water inlet channel is arranged through the axis of the first horizontal part, and a water outlet hole is provided at the bottom of the cavity; a baffle plate is arranged at the end of the second horizontal part; a second piston is arranged in the second horizontal part, and a pressure regulating spring is arranged between the second piston and the baffle plate, and a gas filling port is provided on the second piston, and a conical one-way valve is arranged in the gas filling port; an air inlet pipe, one end of which is connected to the water inlet channel, and the other end of which is connected to the water inlet channel in the second horizontal part through the air inlet valve. The space between the baffle and the second piston is connected; a speed regulating motor is arranged outside the top of the cavity, and its rotating shaft is located in the cavity and is connected to a rotating impeller; a cylinder body is arranged in the cavity and below the rotating impeller, and its middle inner diameter is larger than the inner diameters at both ends; an upper orifice plate is arranged on the top of the cylinder body, and a first flow hole is opened on it; a lower orifice plate is arranged on the bottom plate of the cylinder body, and a second flow hole is opened on it; a piston rod, the top of which is connected to the upper orifice plate, and the bottom of which is connected to the lower orifice plate; a piston is sleeved on the piston rod, and an upper spring is connected between it and the upper orifice plate, and a lower spring is connected between it and the lower orifice plate.

[0007] Furthermore, a waterproof base pad is provided between the motor and the top of the cavity, and the motor, the waterproof base pad and the cavity are connected by fastening bolts.

[0008] Furthermore, a shearing membrane net is arranged in the cavity between the cylinder body and the water outlet, and shearing holes are arranged in the shearing membrane net.

[0009] Furthermore, the second horizontal portion is connected to the baffle through an adjusting thread.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the frequency and amplitude are precisely controlled by the reciprocating motion of the first piston, so that the system reaches an efficient resonance state, and micro-nano bubbles can be released efficiently. At the same time, the device cleverly adopts a self-priming air intake method to automatically and continuously replenish the required gas. This design not only greatly overcomes the defects of insufficient gas replenishment and low efficiency in traditional micro-nano bubble generation methods, but also significantly increases the gas intake, providing sufficient raw materials for the generation of micro-nano bubbles.

[0011] In addition, under the dual effects of resonance and self-priming air intake technology, the equipment effectively increases the number of micro-nano bubbles produced and makes the size of the bubbles more uniform, which is of great significance for improving the application effect of the bubbles. In addition, the overall structural design of the equipment is simple and clear, without unnecessary complex components, which not only reduces the production cost, but also makes the maintenance of the equipment more convenient.

[0012] In general, the micro-nano bubble generating device that achieves a resonant state through the reciprocating motion of the piston and combines a self-priming air intake method has broad application prospects and significant market competitive advantages in related fields due to its efficient gas intake, large amount of bubble output, uniform bubble size, low cost and simple structure.

The rotating impeller 6 and the rotating shaft 7 are located directly above the cylinder body 10. The rotating impeller 6 has a spiral structure. The piston rod 8, the upper spring 21, the first piston 11 and the lower spring 26 are all located on the inner side of the cylinder body 10. The aperture sizes at both ends of the inner side of the cylinder body 10 are larger than the central aperture size. The first piston 11 is located at the center of the cylinder body 10. The end of the upper spring 21 away from the first piston 11 is fixedly connected to the bottom of the upper orifice plate 23, and the end of the lower spring 26 away from the first piston 11 is fixedly connected to the top of the lower orifice plate 27.

[0022] The working principle of the above technical solution is as follows: in the initial state, the first piston 11 is located at the smallest aperture inside the cylinder body 10, i.e., the middle. At this time, the gap between the first piston 11 and the internal hole of the cylinder body 10 is the smallest. At this time, the pressure in the internal space of the pipeline body 1 where the rotating impeller 6 and the rotating shaft 7 are located is large and the flow rate is small. The liquid pushes the second piston 17 to compress, the conical one-way valve 13 is opened, and the intake valve 16 is closed. The gas inside the pipeline body 1 where the second piston 17 is located flows through the conical one-way valve 13 to the internal space of the pipeline body 1 where the rotating impeller 6 and the rotating shaft 7 are located. The gas is sheared into larger bubbles by the rotating impeller 6 and the rotating shaft 7, and the liquid enters the gradually shrinking and expanding hole (internal hole) through the first flow hole 24 of the upper orifice plate 23. The first piston 11 is in Under the impact of liquid pressure, the first piston 11 accelerates axially in the direction of liquid flow, compresses the lower spring 26, and stretches the upper spring 21. As the first piston 11 moves, it gradually deviates from the throat of the internal hole of the cylinder body 10, so that the gap between the first piston 11 and the internal hole of the cylinder body 10 becomes larger and larger, resulting in the liquid impact pressure on the first piston 11 becoming smaller and smaller, reaching the balance point between the liquid impact pressure and the combined force formed by the upper spring 21 and the lower spring 26. At this time, the acceleration of the first piston 11 is zero, but due to the inertia of the fluid and the first piston 11 itself, the first piston 11 will not stop at this point, but will continue to move while decelerating, and finally reach the farthest position below the internal hole of the cylinder body 10. The first piston 11 is located at the expansion of the internal hole of the cylinder body 10. When the first piston 11 reaches the farthest position at the bottom and the gap with the hole is the largest, the pressure in the internal space of the pipeline body 1 where the rotating impeller 6 and the rotating shaft 7 are located is small and the flow is large, the pressure regulating spring 15 is released, the conical one-way valve 13 is closed, and the air inlet valve 16 is opened, and the external gas enters the second horizontal part 1-3 through the air inlet valve 16. Since the combined force of the compressed lower spring 26 and the restoring force of the pulled upper spring 21 is greater than the pressure of the liquid on the first piston 11, the first piston 11 moves axially against the flow direction of the liquid and gradually approaches the throat of the hole inside the cylinder body 10, so that the gap with the hole becomes smaller and smaller. Since the pressure rise of the liquid pump lags behind the movement of the first piston 11, the first piston 11 passes through the cylinder body 10 under the action of inertia. The throat of the hole in the lower part, and decelerates when compressing the upper spring 21 and stretching the lower spring 26. At the same time, due to the hysteresis effect, the pressure in the internal space of the pipeline main body 1 where the rotating impeller 6 and the rotating shaft 7 are located gradually rises, the second piston 17 is compressed, the conical one-way valve 13 is opened, and the intake valve 16 is closed. The internal gas in the pipeline main body 1 where the second piston 17 is located flows through the conical one-way valve 13 to the internal space of the pipeline main body 1 where the rotating impeller 6 and the rotating shaft 7 are located, further decelerating the first piston 11 and finally reaching the farthest position at the top. Under the combined force of the compressed upper spring 21, the stretched lower spring 26 restoring force and the liquid pressure, the first piston 11 makes axial movement in the direction of liquid flow to start a new cycle.In this way, the reciprocating motion of the first piston 11 will eventually cooperate with the internal space of the pipeline body 1 where the rotating impeller 6 and the rotating shaft 7 are located and the liquid pressure to make the generating mechanism reach an efficient resonance state. By adjusting the rigidity of the lower spring 26 and the upper spring 21 and adjusting the gap between the first piston 11 and the internal throat of the cylinder body 10, the resonance frequency of the generating mechanism can be changed to make it work in the best micro-nano bubble release state.

[0023] In another embodiment, Figure 1-Figure 5 As shown, a shearing film net 9 is fixedly installed inside the pipe body 1 , and the shearing film net 9 is located directly below the cylinder body 10 . A shearing hole 12 is opened inside the shearing film net 9 , and a water outlet hole 22 is opened at the bottom of the pipe body 1 .

[0024] Finally, under the action of the circular shearing membrane net 9 and the water outlet hole 22 , the micro-nano bubbles with large particle sizes are further sheared into smaller sizes and then discharged through the water outlet hole 22 .
