Description

A kind of cold spray gun
Technical field
A kind of spray gun for cold spray is the utility model is related to, belongs to field of fluid machinery.
Background technology
Organic coating is made to be used as corrosion-inhibiting coating, is industrially widely used, such as oil pipeline, marine ship Deng.For the customary preparation methods of coating just like the flame spraying method of routine, this method requirement is higher to the preheating temperature of matrix, holds Matrix structure is easily influenceed, for organic coating, spraying flame easily causes scaling loss and the degraded of organic dust;Other electrostatic Spraying and coating prepare conventional method, but this method can not site operation, therefore for the joints such as such as oil and gas pipeline, It is prepared by the coating on the surface of the parts such as three-way pipeline, generally use spread coating.Brushing organic coating, due to containing organic molten Agent, when organic solvent volatilizees, coating can be caused micropore occur, form the hidden danger of coating corrosion;The coating brushed in addition is relatively thin, Typically to pass through multiple tracks brushing, long construction period;Again due to main pipeline spray-on coating and the brushing coating layer thickness of joint, quality Inhomogeneity, make joint and valve, threeway of pipeline etc. place turn into corrosion protection weak link.
Cold spray is a kind of relatively effective preparation method of organic coating, and cold spray is taken using by certain gases at high pressure Band powder particle enters jet pipe and produces supersonic speed two phase flow, and powder particle hits matrix after acceleration with solid state, produces Violent plastic deformation and be deposited on matrix surface and form coating.The conventional single hose spray gun of current cold spray, can be present such as:One Secondary heating powder, organic material melt in lance pipe, when spraying stopping, blocking jet pipe;Powder is anxious when running into matrix Speed is cooled into coating, has little time to flow, therefore the planarization of spray-on coating is poor, the poor bonding strength of coating.
Utility model content
The utility model is directed to existing coating when the cold spray gun used in the prior art is sprayed and blocks jet pipe and painting Layer poor two technical problem of planarization, intend providing a kind of cold spray gun, mesh is asked by what improvements of facility reached improvement coating quality 's.
In order to reach purpose of utility model of the present utility model, the technical solution adopted in the utility model is:
The utility model provides a kind of cold spray gun, and the cold spray gun includes hopper, powder pre-heating system, the powder for providing powder Expect paint finishing and coating reheat system;Powder pre-heating system is arranged at the front end of hopper, includes heating voltage controller, gas Body heating coil and gas flow control valve, it is connected by pipeline with hopper;Powder paint finishing include heating voltage controller, Gas heating coil and gas flow control valve and tubular type spray gun, tubular type spray gun set are the powder delivering pipe being connected with hopper On road, and the end port of powder carry pipeline is discharging opening in tubular type spray gun;Tubular type spray gun afterbody is in the opposed shape of two loudspeaker;Powder Material is transported on matrix by the afterbody horn mouth of tubular type spray gun and completes to spray;Coating reheat system controls including heating voltage Device, gas heating coil and gas flow control valve and air shooter, are reached by the hot blast of heating by air shooter The coating of spraying is completed.
The beneficial effects of the utility model are:By increasing pre-heating system and carrying out powder heating in spout, and Further coating reheating so that the utility model overcomes the technology that prior art coating blocks jet pipe and coating planarization difference Problem, the adhesive force of coating is improved, porosity declines, and coating quality improves.
Brief description of the drawings
Fig. 1 is the schematic diagram of cold spray gun of the present utility model.Wherein 1 is matrix, and 2 be heating voltage controller, and 3 be gas Heating coil, 4 be gas flow control valve, and 5 be hopper, and 6 be air inlet, and 7 be tubular type spray gun, and 8 be coating.
Embodiment
The utility model is further illustrated below in conjunction with drawings and the specific embodiments.
Such as Fig. 1, a kind of cold spray gun is present embodiments provided, the cold spray gun includes providing the hopper of powder, powder preheating system System, powder paint finishing and coating reheat system.Powder pre-heating system is arranged at the front end of hopper, includes gas heater wire Circle, heating voltage controller and gas flow control valve, are connected by pipeline with hopper;Powder paint finishing includes heating voltage Controller, gas heating coil and gas flow control valve and tubular type spray gun, tubular type spray gun set are the powder being connected with hopper On material conveying tube road, and the end port of powder carry pipeline is discharging opening in tubular type spray gun;Tubular type spray gun afterbody is in two loudspeaker Opposed shape;Powder is transported on matrix by the afterbody horn mouth of tubular type spray gun and completes to spray;Coating reheat system includes heating Voltage controller, gas heating coil and gas flow control valve and air shooter, the hot blast by heating are defeated by gas Pipe is sent to reach the coating for having completed spraying.
In this embodiment, it is preferred that three powder pre-heating system, powder paint finishing and coating reheat system systems Air inlet be arranged to same.
Heating voltage controller, the gas heating coil of preferable powder paint finishing and coating reheat system share same One set, sets gas flow control valve to control respective gas flow on respective gas pipeline.
During work, air is blown into pipeline, is separately input to powder pre-heating system, powder paint finishing and coating reheating system System;Powder enters pipeline by hopper, is carried out the powder for entering pipeline from powder hopper tentatively by the air of powder pre-heating system Preheating;Powder is only carried out preliminary preheating, the heating voltage control that heating-up temperature passes through powder pre-heating system by powder pre-heating system Device processed is controlled, and makes its temperature at 70-80 DEG C, is not up to molten state, therefore even if subsequently when not working, in pipeline not The coating that after melting and cooling coalesces can be formed and block pipeline.Then powder continues to be transported to the pipeline of powder paint finishing Mouthful, heated in pipeline opening by the hot blast from powder paint finishing, the heating voltage that heating-up temperature passes through powder paint finishing Controller is controlled, and heating-up temperature is 150-300 DEG C, is determined according to the powder sprayed;Powder now reaches melting State, in tubular type spray gun of the pipeline opening by encirclement pipeline opening, in pipe outlet, tubular type spray gun powder reaches molten state, tubular type The horn mouth of use, it is not easy to the accumulation of powder is formed, in addition, tubular type spray gun can be connected with pipeline using detachable, energy Individually dismantled from pipeline, easy cleaning;Powder sprays from the tubaeform muzzle of tubular type spray gun, reaches matrix and hits matrix, produces Raw violent plastic deformation, and cooled down rapidly in matrix surface, and be deposited on matrix surface and form coating;At this moment, the painting of formation Layer is because the quick cooling of coating, have little time to flow, therefore the planarization of spray-on coating is poor, the poor bonding strength of coating;Now, The coating just formed, the hot blast blown out by coating reheat system, remelted and levelling again, form more smooth painting Layer.Preferably, mounted cold spray gun, the muzzle of its tubular type spray gun is with the air outlet of coating reheat system at a distance of 1-2cm.
