Description
Technical field
The present invention relates to the dual component material spray equipment that a kind of spray gun, passage and storage tank constitute, the double component nanometer material spray gun that particularly a kind of spray tip, blending bunker, rifle body and handle constitute.
Background technology
" the foam gap filler spray gun " of CN2505181Y comprises barral of a gun, rifle body and handle, and this architectural feature mainly is applicable to the narrow slit filling, for quick cap holes or tunnel emitted dose deficiency, and does not have the material dispenser.
" the foam distribution rifle " of USP4399.930, this patent structure device is to be communicated with spray gun by two raw material storage tanks by feeder sleeve to constitute, its spray gun structure is to be provided with inlet valve on handle, by connecing the charging aperture that mouth is communicated with sprinkler body, be provided with slot on both sides, sprinkler body frame lower surface, and in the slot with the corresponding insert edge insertion in both sides, handle upper surface sprinkler body frame, the place is hinged with trigger at sprinkler body frame outer wall pivot point, and make trigger rotation roof pressure needle make the needle switch, be provided with chute and be communicated with fixing hole at sprinkler body frame middle part, and two sprinkler body fixed axis on the sprinkler body are packed in the fixing hole on the sprinkler body frame, it is corresponding with the valve body discharging opening and be connected that two charging apertures of sprinkler body connect mouth by two.This spray gun structure complexity, very narrow during the material spraying through the runner of needle-valve, to stop up easily, cleaning is inconvenient, and flow is little, dismounting inconvenience.Especially the control valve in this rifle body is cylindrical, and rotation brings the spraying fault easily when spraying.Also having the nozzle of spray gun shower nozzle is the roundlet hole shape, and the material that is sprayed during spraying is cylinder or some spraying, can not satisfy large-area fast spraying requirement.
Disclosed CN1672803 nanometer material spray gun, be provided with the shower nozzle of positive and reverse return batch mixing reaction warehouse in this spray gun, connect the rifle body feed bin of shower nozzle and the rifle body of feed bin ingress pipe and control valve, be articulated in the spray gun handle that is connected on Switch of spray pistol handle on the rifle body bonnet and quantity for spray handle control piece and the rifle body.This spray gun has been simplified internal structure, it is efficient and convenient to make mounting or dismounting clean, but this spray gun makes that material hybrid reaction in actual spraying process is even inadequately owing to simplified internal structure, and because the problem of nozzle arrangements and emitted dose does not satisfy the requirement of large tracts of land fast spraying.
Above-mentioned existing dual component material spray equipment, in actual application, when its subject matter still solves not spray gun spraying fortunately, the relation of its spraying material mixture velocity and spray gun mixed structure, when spray gun blending bunker complex structure, mixed material flow velocity resistance is big, and mixing of materials is more even, but easily adhesion caking and obstruction, service time is shorter; When the spray gun blending bunker was simple in structure, mixed material flow velocity resistance was little, and flow velocity is fast, solved adhesion caking and blockage problem in the spray gun, service time is longer, but mixing of materials is even inadequately, and the mixed structure of various spray guns all is welded on the rifle body, is not easy to mounting or dismounting and cleans.The inventor is with regard to this problem, once more the spray gun blending bunker is improved, simultaneously at existing spray tip when the shutoff of enforcement large tracts of land hole fast spraying, do not satisfy on-the-spot actual demand, affect the problem on opportunity adversely, nozzle to spray gun improves, and according to simple in structure, easily adorn readily removablely, it is convenient to clean, the principle of fast spraying, and repeatedly on design and the basis of practical application experience, it is even to invent a kind of mixing of materials, economy rational in infrastructure, a kind of spray finishing device for bi-component nano material of applied range.
Summary of the invention
The present invention uses on the basis of double component nanometer material spray gun in design, at the batch mixing structure of the inner blending bunker of existing spray gun and the problem of mixing of materials flow velocity relation, and when implementing the large tracts of land spraying problem of the emitted dose deficiency of nozzle, the spray equipment structure has been done further improvement, its objective is provides a kind of simple in structure, mounting or dismounting are convenient, mix the spray finishing device for bi-component nano material of fast spraying.
The present invention analyzes design around the mixing of materials and the batch mixing structural relation of spray gun, at first considers the homogeneity question that the monocomponent nanocomposite material reaction mixes in the storage filling, the homogeneity question of bi-component nanomaterial reaction mixing in the spray gun; Next is the flow behavior according to the material reaction mixed liquor, material reaction mixes the relation with mixed structure, consider the problem of bi-component nanomaterial tank structure and spray gun internal mix structure, on the basis of designing and using, bi-component nanomaterial tank structure and double component nanometer material spray gun structure are made further improvement, simplify the spray gun internal structure with appropriateness on structure, appropriateness increases the reaction resistance of material and the reaction time of material on the structure, and accomplish to install and remove convenient and swift, mixing of materials is even, spraying spray equipment rapidly and efficiently, concrete technical scheme is as follows:
A kind of spray finishing device for bi-component nano material of the present invention, it contains the storage tank that spray gun is communicated with by passage, and its spray gun comprises the handle that the rifle body of blending bunker connection is connected with the rifle body; Wherein, blending bunker contains blending bunker and import and export thereof, flow distribution plate; The rifle body contains seal bar and spring, feed bin A feed pipe and rifle body feed bin B feed pipe, bonnet handle bearing, feed bin sealing pole spacing head, handle socket and the fixing threaded hole thereof that feed bin sealing plate and outlet thereof, seal head connect; Handle contains feed bin A feed pipe and feed bin B feed pipe and control valve thereof, handle plug; Switch knob contains handle control screw hole, and handle bearing hole and handle connecting hole is characterized in that: described blending bunker is provided with one-level and sprays blending bunker I, two stage countercurrent blending bunker II and three grades of overflow blending bunker III; One-level is sprayed blending bunker I and fixedly is made of the connector that the arc that circumferential edge is provided with material outlet is fitted in blending bunker and rifle body; Two stage countercurrent blending bunker II are provided with runner by the centre
The shape plectane is supported on the bearing folder, and its underpart is provided with material outlet
The shape plectane is supported on the bearing folder and goes up formation; Three grades of overflow blending bunker III are provided with runner by the centre that is supported on the bearing folder
