Description

A kind of micro-nano bubble spray head of auto-excitation type
Technical field
The utility model category spray head technical field is related to a kind of micro-nano bubble spray head, and in particular to a kind of self-excitation declines Nano bubble spray head.
Background technique
In sewage treatment, micro-nano bubble air flotation technology is largely used.Micro-nano bubble spray head is at sewage The component that usage quantity is most in system equipment is managed, and spray head blocking is the major failure in micro-nano air bearing sewage treatment.
The working principle of micro-nano bubble air flotation technology: it exactly goes to wrap up with the bubble more than 10 times or more quantity, sewage In suspended pollution particle, force suspended pollution particle to float on the surface of the water, collect concentrate, then drying and other treatment is fallen.Bubble will wrap up Particle is polluted, the partial size of bubble is necessarily less than pollution particle three times or more, therefore the higher the better for nanoscale bubble percentage.Only Have and most tiny pollution particle is taken clean, water could be so clear that you can see the bottom.
That there are outlet gaps is small for existing micro-nano bubble spray head, easy blocking, the micro-nano bubble diameter that generates are biggish Shortcoming.
Utility model content
Avoid that blocking, structure are simple, it is smaller to produce more partial sizes the purpose of this utility model is to provide one kind The micro-nano bubble spray head of the auto-excitation type of micro-nano bubble, to solve shortcoming in the prior art.
The technical solution adopted in the utility model is: a kind of micro-nano bubble spray head of auto-excitation type, including hollow sprayer body, From sprayer body one end by screwing into the nozzle boss of sprayer body, nozzle boss and sprayer body are inserted into from the sprayer body other end The sprinkler core of inner wall cooperation clamping, the space between the sprayer body other end and sprinkler core one end are that mixed liquor enters room, institute It states sprinkler core center and is equipped with 90 degree of water conservancy diversion taper holes being connected to the mixed liquor room of entrance, 90 degree of deflection cone hole exits are ultra-thin injection Mouthful, described nozzle boss one end is equipped with the ring port being connected to ultra-thin jet port, and center is reversed equipped with being connected to ring port Diversion cavity, ring port, which extends downwards, is formed with circumference gas bubble generating area, and circumference gas bubble generating area is communicated with that lead to nozzle boss another Multiple micro-nano bubble squit holes of one end.
Further, the reversed diversion cavity is cylindrical, and both ends are equipped with arc training wall.
Further, the spray head body sidewall is equipped with the pressurized gas inlet being connected to the mixed liquor room of entrance.
Further, the spray head body sidewall is equipped with the low-pressure gas entrance being connected to circumference gas bubble generating area.
Further, the sprayer body passes through the tight fit clamping corresponding with sprinkler core inner wall of two sections of different outer diameters.
Further, the sprayer body is equipped with the internal screw thread being threadedly coupled with mixed liquor efferent duct in the mixed liquor room of entrance.
Further, the ring port widens 30-35% relative to existing spray head, is not easy to plug this spray head.
The utility model compared with prior art, has the advantages that
1, the utility model auto-excitation type bubble spray head only has three nozzle boss, sprayer body, sprinkler core part compositions, structure letter List, production cost are low, and mixed liquor collides with each other to form self-excitation phenomena in the reversed diversion cavity of nozzle boss, and gas and liquid are carried out Further strong mixing, produces the smaller micro-nano bubble of more partial sizes.
2, the utility model ozone can be added from pressurized gas inlet, ozone conduct by setting pressurized gas inlet The gas source of micro-nano bubble, what spray head generated is " the micro-nano bubble of ozone ", is diffused into whole water bodys of processing pond, smelly Coefficient of oxygen utilization is higher than 95%.
3, the utility model is added by setting low-pressure gas entrance, ozone from low-pressure gas entrance, and ozone meeting " is wrapped up in and taken " The diffusion of micro-nano bubble, ozone utilization rate be higher than 80%.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1 and Figure 2, the micro-nano bubble spray head of a kind of auto-excitation type of the utility model, including hollow sprayer body 1, from Sprayer body one end is inserted into nozzle boss 2, by two sections by screwing into the nozzle boss 2 of sprayer body 1, from the sprayer body other end Different outer diameter and 1 inner wall of sprayer body are fitted close the sprinkler core 3 of clamping, between 3 one end of 1 other end of sprayer body and sprinkler core Space is that mixed liquor enters room 4, and 3 center of sprinkler core, which is equipped with, to be entered 5,90 degree of 90 degree of water conservancy diversion taper holes that room 4 is connected to mixed liquor and lead The outlet of flow cone hole 5 is ultra-thin jet port 6, and 2 one end of nozzle boss is equipped with the ring port 7 being connected to ultra-thin jet port 6, and center is equipped with The reversed diversion cavity 8 of the cylinder being connected to ring port 7, ring port 7 are widened 30-35% relative to existing spray head, are reversely led It flows 8 both ends of chamber and is equipped with arc training wall 9, ring port 7, which extends downwards, is formed with circumference gas bubble generating area 10, and circumference bubble generates Area 10 is communicated with the multiple micro-nano bubble squit holes 11 for leading to 2 other end of nozzle boss, and 1 side wall of sprayer body is equipped with and mixed liquor Into room 4 be connected to pressurized gas inlet 12, the low-pressure gas entrance 13 being connected to circumference gas bubble generating area 10, sprayer body 1 in Mixed liquor enters room 4 and is equipped with the internal screw thread being threadedly coupled with mixed liquor efferent duct.
As shown in figure 3, the gas and liquid mixture from gas-liquid mixing pump enters room 4 into spray head, in 90 ° of water conservancy diversion from mixed liquor The flow direction of mixed liquor is reduced to 0 ° of formation umbrella jet stream to rush at reversed diversion cavity from 45 °, 25 ° to center under the action of cone 5 8, it rapidly returns, is returned in reversed diversion cavity 8 along jet stream because being oriented to by arc training wall 9, due to arc after being rebuffed The self-excitation jet stream 14 of R z bend is formed under the action of shape training wall 9, R z bend jet stream is in jet stream voluntarily excitation area 15 It collides with each other to form voluntarily induced phenomenon with the power stream 16 moved forward, inspires the fluid of many and diverse high-speed stirred, it is many and diverse The fluid of high-speed stirred causes very big resistance to the flowing of mixed liquor, and gas is further mixed strongly with liquid progress, 150 nanometers to 4 microns of bubble diameter of bubble is produced in circumference gas bubble generating area 10, from multiple micro-nano bubble squit holes 11 Middle ejection.
Above embodiment is specific embodiment of the utility model, be not intended to limit the implementation of the utility model with Interest field, all equivalence changes and modification made according to content described in utility model application scope of patent protection, should all wrap It includes in present utility model application the scope of the patents.
