Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
The specific embodiment
as shown in Figure 1, the utility model discloses a kind of concrete gun, comprise the spray gun body that nylon material is made, its profile is substantially the revolving body structure, described spray gun body center is provided with the concrete access way 1 of perforation, the direction of concrete material turnover spray gun indicates with arrow, also be provided with auxiliary agent import 2 on described spray gun body, auxiliary agent passage 3, air intlet 4, air duct 5, annular eddy flow chamber 6 and aerosol passage 7, described auxiliary agent import, the auxiliary agent passage, annular eddy flow chamber and aerosol passage are communicated with successively, described air intlet, air duct, annular eddy flow chamber and aerosol passage are communicated with successively, the outlet of aerosol passage is located on the wall of described concrete access way.Described auxiliary agent import and air intlet are symmetrical with respect to the axis of described concrete access way substantially, and its axis separately is parallel with the axis of described concrete access way.auxiliary agent enters from the auxiliary agent import, enter annular eddy flow chamber through the auxiliary agent passage, compressed air enters from air intlet, enter annular eddy flow chamber through air duct, auxiliary agent is atomized in annular eddy flow chamber under compressed air is swept along, the auxiliary agent that becomes gas phase mixes also more even with compressed air, mixture both enters described concrete access way rapidly by the aerosol passage, the even blending of concrete wet feed that enters with feed end from the concrete access way again, concrete wet feed after blending is also spouting by the concrete access way fast under compressed-air actuated promotion.Compressed-air actuated Main Function is that the motive force of outside injection is provided for entering concrete in spray gun.
Described auxiliary agent import and air intlet connect respectively auxiliary agent and air to be carried and uses valve, realizes the purpose of switch and/or Flow-rate adjustment.
The described concrete access way of the coaxial encirclement in described annular eddy flow chamber, described aerosol passage can be for a plurality of, as 6-12, the medium that its import is located at described annular eddy flow chamber flows out on the wall of a side, and even circumferential distributes centered by the axis of described concrete access way.The 1/3-1/2 in auxiliary agent passage and air duct equivalent aperture is arranged in the equivalent aperture of aerosol passage, and the mixture that can effectively improve compressed air or compressed air and auxiliary agent enters speed and the impulsive force of described concrete access way.Between the axis of each described aerosol passage and described concrete access way, angle can be 20-45 °, and the outlet of described aerosol passage is towards the discharge end of described concrete access way.Between the axis of described aerosol passage and described concrete access way, angle is preferably 20-25 °, if this angle too small, the discharge end of the described concrete access way of outlet distance of aerosol passage will be excessively near, auxiliary agent and concrete blending time will be partially short, be unfavorable for that auxiliary agent fully mixes with concrete, do not wish again to extend auxiliary agent and concrete incorporation time if do not change this angle, need to lengthen the length of discharge end one side of described concrete access way; And if this angle is excessive, the component of power on the axis direction of described concrete access way that auxiliary agent and compressed-air actuated mixture are applied on the concrete wet feed will be less, is unfavorable for promoting concrete injection.
The feed end of described concrete access way is fixed with the conveying pipeline joint of metal material; be used for connecting the pipeline of delivering concrete wet feed; can one metal lining be set to protect the inwall of this section by heat cure on one section inwall of feed end, extend its service life.In the present embodiment, above-mentioned conveying pipeline joint and lining are two parts of same joint part 8, and this two-part internal diameter is a continuous gauge structure such as grade.The outer wall of described lining is the conical surface or the ladder cylinder that forms for the Cylinder Combination that do not waited by some diameters, and the outer diameter the closer to described conveying pipeline joint is larger, by lining and the heat cure of spray gun body, realizes this joint part being connected and fixing on spray gun.
Do not arrange on the inwall of part of described concrete access way of lining wear-resisting, corrosion-inhibiting coating (not looking out in figure) can be set; further to protect the inwall of described concrete access way, and can extend the service life of spray gun by the reparation to coating.
in order to improve the mixed effect of compressed air and auxiliary agent, the present embodiment carries out following optimization setting to described auxiliary agent passage and air duct: make axis both become the space different surface beeline, and the axis with respect to described concrete access way is obliquely installed, the outlet that makes two passages is all towards the discharge end of described concrete access way, make the projection of axis on the plane of the axis perpendicular to described concrete access way of described auxiliary agent passage and air duct all be clockwise or all be counterclockwise, make compressed air and auxiliary agent enter annular eddy flow chamber along spatially spiral line direction respectively and form eddy flow, under compressed-air actuated pressure and impact force action, auxiliary agent is being broken up atomization, and at the edge of compressed air stream, entrainmented into gradually realization and compressed-air actuated even the mixing.
Described spray gun body consists of body of feedstock a and nozzle b two parts thread connection, mounting or dismounting are convenient, the central evagination of described body of feedstock center female parts and nozzle partly surrounds described annular eddy flow chamber, the center through hole of described body of feedstock and the center through hole of nozzle are joined and are formed described concrete access way, described lining is fixed on the center through hole wall of described body of feedstock, described auxiliary agent import, auxiliary agent passage and described air intlet, air duct are located on described body of feedstock, and described aerosol passage is located on described nozzle.As shown in Figure 1, the center through hole of described body of feedstock runs through wherein intracardiac concave portion, and the circumferential edges that runs through the center through hole of position is provided with male cone (strobilus masculinus).The central evagination of described nozzle partly is provided with inner conical surface, and under confined state, described male cone (strobilus masculinus) and inner conical surface offset, and makes described annular eddy flow chamber, auxiliary agent passage, air duct and described concrete access way not connected.
The center through hole of described nozzle can be circular hole, can be also its part or all be taper hole, described taper hole is less near the aperture of discharge end one side of described concrete access way, in the situation that the input concrete flow quantity remains unchanged, can further improve jet velocity and dynamics, be conducive to improve spray efficiency, improve concrete at the adhesion effect by sprayed surface.
