In order to preferably spray air-water mixture to brush portion 108, the diameter of the fixed ring 103 is less than in horizontal direction
The width in brush portion 108, the width in this brush portion 108 are maximum width.
In order to which the rubbish and air-water mixture that siphon away to positive pressure vacuum brush mechanism settled, is separated, the discharge pipe
It is connected with second level flow tank 9, second level flow tank 9 is connected with air filter 10, and air filter 10 is connected to air power source 7
On.
Above-mentioned level-one flow tank 8 can be structure as shown in Figure 3, and the case ontology including only upper end opening (is not marked in figure
Out), horizontal filter screen II 802 is provided in case ontology, case ontology is divided into upper layer waste compartment to filter screen II 802 and lower layer stores up
Water chamber, for rubbish and water to be isolated, the side of lower layer's reservoir chamber is provided with the tap (being not drawn into figure) to discharge water, case ontology top
Portion is installed with filter screen I 801, filter screen I 801 close to second level flow tank 9 side and edge be fixed in discharge pipe, filter screen
I 801 is different with II 802 mesh of filter screen；The structure of second level flow tank 9 is identical as the structure of level-one flow tank 8, but thereon
The mesh of filter screen is different, and mesh need to be determined according to the substance for wanting filtering.Certainly, level-one flow tank 8 and second level are heavy
Case 9 or other existing flow tanks or waste water treatment box that can play said function drop.Level-one flow tank 8 and second level are heavy
Drop 9 top of case is packed on discharge pipe.
When work, the mixture of sewage, rubbish and air, which is driven through discharge pipe by positive pressure vacuum, successively to be settled by level-one
Case 8, second level flow tank 9, air filter 10 are back to air power source 7, in above process, in the blocking of filter screen I 801
Under, bulk rubbish and sewage are blocked and naturally fall in level-one flow tank 8, under the action of filter screen II 802 bulk rubbish and
Sewage is completely separated, and sewage enters in the reservoir chamber of II 802 lower section of filter screen, and air and fritter rubbish pass through filter screen I 801
Into second level flow tank 9, in the case where first filter screen (not marking in figure) at 9 top of second level flow tank hinders, fritter rubbish and portion
Divide and fall under water, the first filter screen of air permeable enters air filter 10, obtains clean air after filtering, is then back to
Air power source 7.
For the ease of controlling the ratio of water and air, solenoid valve 5 is separately installed on the water pipe and air hose.
The present invention also provides a kind of positive pressure vacuum dust collecting systems, including the air/water composite cleaning device.
Further, positive pressure vacuum brush mechanism 1 is separately positioned on cleaning vehicle in the air/water composite cleaning device
(being not drawn into figure) two sides, the jet pipe 3 of inclined downward backward is provided in the middle part of cleaning vehicle, and the bottom of cleaning vehicle is arranged in jet pipe 3
Portion, jet pipe 3 are connected to venturi mixer 4, are provided with positive pressure vacuum mechanism II 2 on rear side of jet pipe 3, positive pressure vacuum mechanism II 2 with
There are gap between ground, the suction inlet of positive pressure vacuum mechanism II 2 is tilted to 3 direction of jet pipe, enters positive pressure vacuum convenient for rubbish
Mechanism II 2, positive pressure vacuum mechanism II 2 are identical as I structure of positive pressure vacuum mechanism.
For the ease of first carrying out once settling to reduce reentrainment of dust to bulk rubbish, the positive pressure vacuum mechanism II 2
Discharge pipe is connected with level-one flow tank 8, and level-one flow tank 8 is connected on second level flow tank 9.
Preferably, the positive pressure vacuum brush mechanism 1 in cleaning vehicle the same side is at least one, and particular number is according to clear
Carwash width and ground actual conditions determine, not more than three, are in interlaced arrangement when it is two or more, can prevent in this way
Gap between two adjacent positive pressure vacuum brush mechanisms 1 clean less than.
Rubbish for the ease of not siphoning away to positive pressure vacuum brush mechanism 1 carries out thorough cleaning, the positive pressure vacuum mechanism
II 2 two sides are respectively arranged with the baffle 11 that front extends outward, and the outermost of baffle 11 is close to positive pressure vacuum brush mechanism
1, as shown in Figure 1, there are holes between 11 bottom of baffle and ground to accept the rubbish that positive pressure vacuum brush mechanism 1 does not siphon away
Gap, this hole is smaller, rubbish cannot be allowed by being advisable.When work, the mainly fugitive dust that positive pressure vacuum brush mechanism 1 siphons away,
The brush portion 108 of positive pressure vacuum brush mechanism 1 rotates to II 2 direction of positive pressure vacuum mechanism carry out brush respectively, and such positive pressure is true
The rubbish that empty brush mechanism 1 does not siphon away will rotate into the front of baffle 11 with brush portion 108, and baffle 11 is by positive pressure vacuum brush
The rubbish that mechanism 1 does not siphon away is imported into the cleanup area of jet pipe 3, carries out thorough cleaning.
108 diameter of brush portion in above-mentioned positive pressure vacuum brush mechanism 1 can be 40cm, the bottom of positive pressure vacuum mechanism II 2
Portion's size can be 2m or more, and to adsorb most of rubbish, it may be other sizes certainly.
When the invention works, air a part that air power source 7 generates is respectively enteing positive pressure vacuum brush mechanism 1 just
It presses in vacuum mechanism I and the air inlet shell 102 of positive pressure vacuum mechanism II 2, passes through air inlet 102 lower end of shell and suction inlet shell
101 generate Coanda effect, generate Involving velocity, to form positive pressure vacuum, positive pressure vacuum driving fritter rubbish enters positive pressure
Vacuum mechanism I and be cleaned, bulk rubbish enters the cleaning of intermediate positive pressure vacuum mechanism II 2 under the rotation in brush portion 108
Range；The water that another part air and water tank 6 generate is mixed by venturi mixer 4, forms air-water mixture, mixing wastewater with air
Object respectively enters the fixed ring 103 and jet pipe 3 of positive pressure vacuum brush mechanism 1, and to carry out air water injection, jet pipe 3 is in cleaning vehicle
Portion carries out high pressure washing, and rubbish is rushed to the suction inlet of positive pressure vacuum mechanism II 2, carries out positive pressure absorption, the height in fixed ring 103
Pressure nozzle 104 is sprayed, and the part of injection flows to brush portion 108, and the water in another part carries out depositing dust, air promotes just
Press the formation of vacuum.The sewage rubbish mixture of the discharge pipe suction of positive pressure vacuum mechanism I enters second level flow tank 9, and positive pressure is true
The sewage rubbish mixture of the discharge pipe suction of empty mechanism II 2 is introduced into level-one flow tank 8 and enters back into second level flow tank 9, air
Filter 10, the filtered air return of air filter 10 to air power source 7 are recycled.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without depart from that overall concept of the invention, several changes and improvements can also be made, these also should be considered as of the invention
Protection scope, these all will not influence the effect and patent practicability that the present invention is implemented.
