Description
Technical field
The present invention relates to Dry ice cleaning field more particularly to it is a kind of with stablize dry ice flow to function Dry ice cleaning spray
Mouth.
Background technique
Dry ice cleaning is also known as cold spray, is using compressed air as power and carrier, is accelerated particle with dry ice particles,
It is ejected into cleaned body surface by dedicated jet cleaner, it will not be to cleaned body surface, especially metal surface
It causes any harm, the finish of metal surface will not be influenced.In order to reach good dry ice blasting effect, dry ice spray head
It designs very important.
As shown in Figure 1, it discloses one kind in existing patent document (patent application publication number, CN107377531A)
Dry ice snowflake cleaning nozzle device, including nozzle body, the outer cover and pedestal that are connect with nozzle body；There is CO in nozzle body2
Spray head, by the CO being mounted in pedestal2Connecting tube compresses；Base side wall has inlet for pressurised gas, the CO of pedestal2Import and CO2Spray
The CO of head2Outlet between form CO2Channel, around stating CO in nozzle body2Spray head ring sets multiple compressed gas through holes；CO2Connection
Compressed gas channel is formed between pipe and pedestal and nozzle body inner wall, outer cover front end has compressed gas outlet opening, nozzle body
Front end stretch out outer cover it is outer after protrude into compressed gas outlet opening and form compressed gas between compressed gas outlet opening inner wall
Mouth is so that compressed gas is discharged through the airflow channel between compressed gas through hole and nozzle body and outer cover inner wall.
In above-mentioned prior art, the compressed gas of preceding case is only discharged via cavity (i.e. airflow channel) at one,
And the nozzle body in preceding case and housing opening are located in same level, the compressed air ejected is dry to what is sprayed
The package degree of ice particle is not strong, does not play the role of stronger current stabilization, the flow direction of dry ice after the injection to the dry ice sprayed
It is not sufficiently stable.
In addition, nozzle body is cylinder, the spray angle of such spray head jet exit is smaller, the model covered after injection
Enclose narrow, the area of cleaning is smaller.
In view of the drawbacks described above of the prior art, it is really necessary to design a kind of improved dry ice cleaning nozzle device.
Summary of the invention
Technical problem to be solved by the present invention lies in: provide it is a kind of with stablize dry ice flow to function Dry ice cleaning spray
Mouth.
In order to solve the above technical problems, the technical scheme is that
It is a kind of with the Dry ice cleaning nozzle for stablizing dry ice and flowing to function, including dry ice jet pipe, compressed air jet pipe and spray
Mouth outer cover；Wherein: dry ice jet pipe has the first air intake duct and the first jet port, and first air intake duct connects dry ice air inlet pipe；

In head A (dry ice air inlet pipe fitting is docked with dry ice air inlet pipe), and limited by the flange.Pass through each section above
Connection, first air intake duct 12 connect with dry ice air inlet pipe (not shown), dry ice gas can by described first into
Air flue 12 is sprayed by first jet port 11 again.The caliber of first air intake duct 12 is from connecting the dry ice air inlet pipe fitting
It is gradually increased at A to first jet port 11.
The compressed air jet pipe 2 has compressed air spray head 25, the second air intake duct 22, the connection compressed air spray head
The interconnecting piece 23 and connection the second air intake duct other end of 25 ends and injection gas one end of second air intake duct 22
Air inlet interconnecting piece 26.Wherein, as shown in figure 3, the compressed air spray head 25 offers the second jet port 21, and the compression
Air nozzle 25 is gradually increased along injection direction until the second jet port from the caliber for the end that it connect with the interconnecting piece 23
At 21, the compressed air spray head 25, which is sheathed on dry ice jet pipe periphery, to be made to form the first gap W between the two；It is described
Interconnecting piece 23 offers several deflector holes for compressing air flow, shunts compressed air here；The air inlet connection
Portion 26 has the cavity that can be accommodated the dry ice jet pipe 1 and circulate for compressed gas, as shown in figure 5, the right side opening of the cavity
Mouth is arranged with the dry ice air inlet pipe fitting A to be connect, and the air inlet interconnecting piece 26 is also provided in its lower end for connecting pressure
The aperture of contracting air inlet pipe fitting B, make compressed air get enter into shown in cavity, flowed via the first gap W
Out；The compressed air inlet pipe connector B, second air intake duct 22 and compressed air are connected by the air inlet interconnecting piece 26
Air inlet pipe (being not shown in the figure, compressed air inlet pipe is connect with compressed air inlet pipe connector B) connection.In the present embodiment,
As shown in figure 5, the interior caliber of second air intake duct 22 is greater than the interior caliber of the interconnecting piece 23, the inner tube of the interconnecting piece 23
Diameter is greater than caliber in the minimum of compressed air spray head 25.
The nozzle outer cover 3 has third jet port 31, housing body 32 and mounting base 33.Wherein, the housing body 3
It is sheathed on 2 periphery of the compressed air jet pipe, forms the second gap Q between the two so as to distribute from the interconnecting piece 23
Blast injection is to the external world；The end of the housing body 32 is connected as one with the mounting base 33, the third injection
