Specific embodiment
The utility model provides a kind of multi-staged air dust removal by filtration device based on Coanda effect, which, which crosses, filters out
Dirt device filtering accuracy is high, high-efficient, and automatization level is high, and manual operation is easy, realizes multi-staged air dust removal by filtration device
Personalization and lightweight.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
Embodiment 1:
As shown in Figure 1, a kind of multi-staged air dust removal by filtration device based on Coanda effect, including the multiplication of Coanda effect air
Getter device, separator, bulky grain collecting box, little particle collecting box, sealing device；The Coanda effect air multiplication air-breathing
Device, separator, bulky grain collecting box, little particle collecting box are sealed inside housings by sealing device, the air multiplication
Getter device is connect with separation module, and the separator bottom is connect with bulky grain collecting box 11, and top and little particle are collected
Case 10 connects, and the setting of air entry 1 is connected to sucking dust-laden exhaust gas, exhaust pipe outside air multiplying assembly front end and shell 13
12 settings are connected to the purified air of conveying with outside at 14 top of case lid.
As shown in Fig. 3 and Fig. 8, the Coanda effect air multiplication getter device includes toroidal shell 2, air intake duct 3 and drum
Blower 4, the air blower 4 are connect by air intake duct 3 with 1 lower end of toroidal shell, and 2 inner hollow of toroidal shell states toroidal shell 2
There is a circle annular fissure 5 in inside, and 2 front end of toroidal shell is connect with air entry 1, and rear end is connect with separator, annular
The width of gap is 1-1.5 millimeters.
As shown in figure 4, the separator includes top connect with air multiplication getter device toroidal shell rear end it is upper
Portion's circular cylinder body 6, intermediate circular cylinder body 7, the conical shell 8 of lower part are equipped with gas-guide tube 9 at the top of the upper circular cylinder 6,
The gas-guide tube 9 is connect with little particle collecting box 10, and filtered fluid, the conical shell 8 of the lower part are filled in little particle collecting box
It is connect with bulky grain collecting box 11 by ash releasing tube 16.
As shown in fig. 6, being additionally provided with exhaust pipe 12 on the little particle collecting box 10, the exhaust pipe 12 passes through case top
It is connected to outside.
As shown in fig. 7, the sealing device includes shell 13 and case lid 14, single unit system and the external world are separated, greatly
Particle collecting bin 11 and little particle collecting box 10 are fixedly connected with the casing by snap ring.
The specific course of work are as follows: the air-flow that Coanda effect air multiplication getter device is provided by air blower 4 is through air intake duct 3
Into air multiplication getter device, because of Coanda effect, air-flow leaves former flow direction, becomes along air multiplier toroidal shell
2 inner ring surface flowing, it is final drive around about 15 times of air flowing, when 35 kilometers of scooter.Have on the inside of toroidal shell 2
One circle annular fissure 5, the width of annular fissure 5 are 1-1.5 millimeters, and the air of high-speed motion is overflowed from ring shake 5, in ring
The negative pressure region that 5 rear of shape crack generates, so that extraneous gas is sucked through air entry 1 and from 2 inside stream of toroidal shell
It crosses, achievees the purpose that suction.
Enter inside separator from the dust-laden exhaust gas of external world's suction, the gas under 8 inner wall disturbance state of conical shell
Motion state becomes circular motion from moving along a straight line.The overwhelming majority of swirling eddy is along upper circular cylinder 6 and intermediate circular cylinder
The wall surface of body 7 is twist downward, flows towards conical shell 8.Dusty gas generates centrifugal force in rotary course, and density is big
It gets rid of in the grit of gas to wall.Grit is once contacted with wall, just lose inertia force and by the momentum of entrance velocity and downwards
Gravity fall along wall surface, fall 16 into ash releasing tube to falling into bulky grain collecting box 11.The outer rotational gas flow of rotation decline arrives
When up to conical shell 8, drawn close due to the contraction of cone to center.According to rotation away from invariance principle, tangential velocity is constantly mentioned
It is high.When air-flow reaches a certain position in cone lower part, i.e., with identical direction of rotation from 8 middle part of conical shell, from bottom to top after
Continuous spin shape flowing, i.e. interior rotational airflow.Lead at this point, the lesser dust particles of density are upwardly into gas-guide tube 9 with interior rotational airflow
Entering to fill the little particle collecting box 10 of filtered fluid, gas comes into full contact with filtered fluid, and the lesser particle of specific gravity is absorbed by filtered fluid,
Remaining clean gas is discharged to the external world through exhaust pipe 12.
Specific embodiment of the utility model is described in detail above, but it is intended only as one such implementation
Example, the utility model are not restricted to particular embodiments described above.To those skilled in the art, any pair of this reality
With the novel equivalent modifications carried out and substitute also all among the scope of the utility model.Therefore, the utility model is not being departed from
Spirit and scope under made equal transformation and modification, should all cover in the scope of the utility model.
