Bubble generator

This creation is directed to a bubble generator, and more particularly to a bubble generator that automatically discharges a blockage and that has a nozzle opening that can be adjusted.

The microbubbles released after decompression of air-dissolved water have been widely and successfully applied to water treatment and other procedures. The smaller the bubble, the longer it stays in the water and the greater the effect.

There are many means for generating bubbles, and the "ultra-fine bubble generator" disclosed in the domestic invention patent No. I245667 uses a multi-stage pump to dissolve air in water to generate a gas and liquid, and to deliver the gas and liquid. The pressure reducing device discharges the gas and liquid instantaneously to generate ultrafine bubbles.

The pressure reducing device is placed in the water tank and includes a main body and a first pressure reducer. The main body has a first end and a second end, the first end is in communication with the conduit, the gas and liquid enters the decompression device from here, and the second end of the main body has a water spray slit of 0.5-0.7 mm, and the gas-liquid is sprayed from the elongated water jet At the time of ejection, ultrafine bubbles are generated due to instantaneous decompression.

The first pressure reducer comprises a casing, a pressure regulating screw and a rotating buckle. The adjusting screw and the rotating buckle are respectively disposed on the casing, and the rotating screw is rotated to rotate the rotating screw to the second end of the main body, and the first pressure reducing device is fixed to the second end of the casing. The main body forms a first impact decompression chamber between the main body and the casing for receiving the ultra-fine bubbles sprayed by the water spray joint for the second decompression.

Because the water spray that provides the gas-liquid spray is narrow, even if the gas and liquid are Before flowing into the equipment, it has been filtered out with a filter to avoid clogging the water spray joint. However, if the treated water system contains industrial waste water and river sewage with solid impurities (such as sludge, sludge, sediment, corroded dead leaves and algae), These impurities are not completely filtered out by the filter. Therefore, after a period of use, the water spray seam will be blocked after a long period of time. If it is not removed, it will cause serious damage to the entire bubble generator. Since the conventional ultra-fine bubble generator does not have the function of automatically discharging the blockage, it must rely on manual removal, which makes maintenance work difficult to simplify.

On the other hand, although it is rotated by the way of adjusting the screw The axial direction of the second end of the main body advances and retreats, and can cover a part of the water spray joint, thereby finely adjusting the size of the water spray joint. However, the pressure regulating screw can only adjust the length of the water spray joint for controlling the water flow rate, and cannot adjust the width of the water spray joint which determines the bubble size.

This creation is made to solve the above problems, and its purpose is to provide one A novel bubble generator can use the sudden increase of pressure to further open the valve to expand the nozzle when the gas-liquid nozzle is blocked, so that the blockage can be automatically discharged with the gas and liquid, simplifying the maintenance work.

Figure 2 is an exploded view of the composition of the creation.

Figure 3 is an axial cross-sectional view of the creative working state, in which the arrows indicate the direction of gas-liquid flow.

Figure 1 is a section of the creation of the "bubble generator" 10, Figure 2 For the component decomposition state, it can explain the technical content of this creation. The bubble generator 10 includes a duct housing 12, a valve 14 and a pressure regulating device 16. Wherein: the pipe casing 12 comprises a first-rate inlet 18 and a first-rate outlet 20, the former for the high-pressure gas-liquid mixture to flow in, and the latter for the gas-liquid to decompress and generate bubbles and then flow out. The outer sides of the inflow port 18 and the outflow port 20 are respectively formed with threaded portions 22 and 24 for connecting the conveying pipe (not shown). For the purpose of manufacture, the duct housing 12 is formed by an inflow side joint 26 and a first-rate outlet joint 28. In the embodiment of the drawing, one end of the inflow side joint 26 is provided with a threaded portion 30, and one end of the outflow side joint 28 is provided with a threaded portion 32, and the two joints are interlocked with each other by the threads 30 and 32, but other Known method connections are not limited by thread locking. The inflow port 18 is provided inside the inflow side joint 26, and the outflow port 20 is formed inside the outflow side joint 28. Further, a valve port 34 is formed between the inflow port 18 and the outflow port 20, and an annular valve seat 36 is mounted on the valve port 34 for use with the valve 14. The valve seat 36 is made of an alloy having high hardness and high strength, such as a titanium alloy, and is subjected to surface treatment, and the crucible can withstand tremendous pressure to avoid deformation and fracture. The inflow side joint 26 has an axially disposed through hole 40 at one end with respect to the valve seat 36 for mounting a guide sleeve 42 for slidably passing through the valve rod 50 to be described later, and being fitted to the inflow side joint The inner leakage stop ring 26 forms a reliable airtight seal between the guide sleeve 42 and the contact surface of the through hole 40 and the valve stem 50, respectively, preventing gas and liquid leakage. In addition, the duct housing 12 further includes a plenum chamber 46 and a decompression chamber 48 formed between the inflow port 18 and the valve port 34 to receive the gas and liquid flowing from the inflow port 18 to make the gas The liquid accumulates here and stabilizes the pressure; the decompression chamber 48 is interposed between the valve port 34 and the outflow port 20, and the gas and liquid ejected from around the valve 14 are decompressed and disturbed here to generate bubbles and free radicals from the outflow port. 20 outflows.

The valve 14 is held by the valve stem 50 to move outside the valve seat 36, which can closely engage the valve seat 36. When the valve 14 is in the open position, the gas and liquid can be looped from between the valve 14 and the valve seat 38. The nozzle 52 is ejected. If not, the valve 14 is moved to the closed (seat) position. In other words, the valve 14 completely closes the valve port 34 and the gas and liquid cannot flow. In the case of a seated engagement, the valve face 54 of the valve 14 mates with the seating surface 38 of the valve seat 36. The valve rod 50 is integrally formed with the valve 14 and extends from the inner side of the valve 14 along the central axis thereof through the guide sleeve 42 and is provided with a threaded portion 56 on the rod body opposite to the end of the valve 14 to cooperate with the latter. The nut 62 is used, and the details are left to be described later. In order to provide a tight fit between the valve 14 and the valve seat 36, in the preferred embodiment, the seating surface 38 formed at the open end of the valve seat 36 and the valve face 54 formed around the valve 14 are both conical and have a taper therebetween. 30 to 60 degrees, preferably 45 degrees.

The pressure regulating device 16 includes a spring 58, a washer 60 and a nut 62. The spring 58 surrounds the valve rod 50 with a compression spring acting on the compression force, one end of which is fitted over the first step portion 64 of the end of the inflow side joint 26 against the first step surface 66 and the other end against the sleeve. On the washer 60 on the valve stem 50, the nut 62 is mounted on the threaded portion 56 of the valve stem 50 to contact the washer 60 such that the spring 58 can be adjusted as the nut 62 advances and retracts along the threaded portion 56. The tension, in turn, changes the size of the nozzle 52 to achieve the purpose of controlling the size of the bubble. It should be noted that in the embodiment of the drawings, the washer 60 is a separate body, but may be integrally formed with the nut 62 such that the washer 60 forms part of the nut 62. Further, the inflow side joint 26 is provided with an inflow side pressure gauge 68 communicating with the plenum 46, The outflow side joint 28 is provided with an outflow side pressure gauge 70 communicating with the decompression chamber 48 to indicate the inflow side and outflow side pressures, respectively. In addition, a protective cover 72 may be further used. The protective cover 72 has a cylindrical shape, one end is closed, and the other end is open to fit over the second step portion 74 of the end of the inflow side joint 26 and against the second step surface 76. It is used to cover the pressure regulating device 16 to prevent the nut 62 from being arbitrarily rotated.

As shown in Fig. 1, the bubble generator 10 is in a stationary state or flows in. When the side gas-liquid pressure is lower than the set spring force, the valve 14 will be held by the spring 58 at the position of the valve seat 36, and the valve port 34 is completely closed, so that the gas and liquid cannot flow.

As shown in Figure 3, when the inflow side pressure is higher than the set spring force, The valve 14 will be pushed away from the valve seat 36 to open the valve port 34 so that the gas and liquid can be instantaneously removed from the periphery of the valve 14, i.e., when the valve 14 is pushed open, by the nozzle 52 defined by the seating surface 38 and the valve face 54. The pressure is ejected, and a second decompression and disturbance are performed in the decompression chamber 48 to generate bubbles and radicals, and then flow out from the outflow port 20.

The size of the bubble generated above depends on the size of the nozzle 52, and the nozzle The size of 52 is closely related to the gas-liquid pressure and the spring force, the former depending on the liquid pump selected, and the latter can be adjusted by the nut 62. Specifically, in a state where the gas-liquid pressure is constant, the spring force is larger, and the smaller the nozzle 52 formed by the opening of the valve 14, the smaller the bubble generated; on the contrary, the smaller the spring force, the larger the nozzle 52 is. The larger the bubbles produced. In addition, this creation can dissolve oxygen, carbon dioxide or ozone into the water as needed, and is not limited by general air. Different sizes of bubbles and gases are suitable for different procedures.

When the gas-liquid pressure on the inflow side is increased because the nozzle 52 is blocked At this time, since the protruding pressure is much larger than the spring force, the valve 14 is further pushed open, so that the nozzle 52 is enlarged with it, so that the blockage can be automatically discharged with the gas and liquid. Once the inflow side pressure returns to normal, the valve 14 is again pulled back into position by the spring 58.

Of course, the above embodiments may be modified without departing from the scope of the present invention, and all the matters included in the above description and the drawings should be regarded as illustrative, and not intended to limit the scope of patent application of the present invention. .
