Description
Technical field
It the utility model is related to fireproof coating painting device technical field, more particularly to a kind of fireproof coating spray gun special.
Background technology
Steel construction is applied to the building such as Standard Factory Room, large-scale stadium, airport, bridge, multi-storied garage more, in order to ensure
Its fire resistance, it will usually in steel structure surface brushing fireproof coating.To improve construction efficiency, fireproof coating construction uses machine
Tool spraying method.Spray gun is automatic arc spraying equipment one of the ost important components.Existing spray gun is sprayed in fireproof coating mechanization
During painting, it is discontinuous spraying often occur, blocks, it is uneven phenomena such as.
Utility model content
The purpose of this utility model is that solve the problems of the prior art, there is provided a kind of fireproof coating spray gun special, tool
When changing fireproof coating spraying, spraying is continuous, uniform, and putty will not occur.
The technical solution adopted in the utility model is：
A kind of fireproof coating spray gun special, including spraying gun body, pipette tips and material cup, the pipette tips are by being threadably mounted at spray
The left end of gun body is applied, the gas channel and one end and the air inlet pipe of gas channel being equipped with the spray gun body inside it
Connection, the other end stretch to pipette tips, the trigger for controlling air inlet pipe throughput are provided with the spraying gun body, for storing
The material cup of fireproof coating be installed on spraying gun body at the top of and by the coating material passage in material cup bottom and inside spray gun body with
Gas channel connects, it is characterised in that：The resonant cavity of an elliposoidal is internally provided with the pipette tips, the gas channel passes through
Inside resonant cavity and installation by adhering has atomizing orifice at terminal position, in the resonant cavity and gas channel vertical direction
Both ends are equipped with through hole and rotation set is provided with hole cap, and the both ends difference position of resonance pin and the pin that resonates is placed with the resonant cavity
In in through hole and lower bounce can be blown in air-flow.
Further, the resonance pin is into cylinder, 1 ~ 2mm of diameter, and length is between resonant cavity long axis length and two
Between the cap distance of hole, it is process by wear-resistant material, such as stainless steel etc..Resonance pin does not interfere with the stream of air-flow and fireproof coating
It is dynamic, and can beat under airflow function, ancillary air stream and fireproof coating mixing, since size limits, the bounce model for the pin that resonates
Enclose and be restricted, will not jump to influences spraying in resonant cavity or in gas channel.
Further, the gas channel is tapered into the junction on the right side of resonant cavity, diameter, and air-flow and fire prevention apply
, can be there are pressure differential when expecting that ejection enters resonant cavity from there, fireproof coating can occur small range and be limited atomization and finally from mist
Change orifice plate atomization to spray, it is favourable to the uniformity and atomization Chengdu of improvement fireproof coating.
The beneficial effects of the utility model are：
There is spraying discontinuously to solve existing spray gun during automatic arc spraying fireproof coating in the utility model,
Block, uneven the problem of waiting, the pipette tips part of spray gun is redesigned.By the resonance that elliposoidal is set in pipette tips
Chamber, can add the strength of resonance of the interior fireproof coating and air-flow by resonant cavity, for the dispersiveness of fireproof coating, uniformity and
Fogging degree all has good effect, and particularly with the coating that viscosity is larger, dispersion effect is more preferable, not putty.Supplemented by meanwhile
The aerodynamic atomization uniformity coefficient for improving fireproof coating sum in resonant cavity is helped, there is provided resonance pin and resonance pin to blow in high-speed flow
It is lower that lasting bounce occurs, dynamic agitation is carried out to the mixture of internal flow fireproof coating and air-flow, improves its uniformity coefficient.
When carrying out the spraying of mechanization fireproof coating using the spray gun in the utility model, spraying is continuous, uniform, and putty will not occur.
