Abstract
The utility model discloses an external mixing gas ejection gun. An auxiliary liquid through-hole is arranged along the axis of the gun body and the nozzle. A main liquid passage is arranged outside the circle of the auxiliary liquid through-hole. A gas passage is arranged outside the front part of the main liquid passage, which is formed as that the gas passage on the gun body is a through cavity, and the gas passage on the nozzle is more than two through-holes communicated with the through cavity and inclined to the axis from the front part of the nozzle. With good effect and high speed in forming waterproof films, the ejection gun can eject and form thicker waterproof films, effectively avoiding the splash of the ejected liquid and the blockage of the nozzle, which has the advantages of flexible and convenient operation, low labor intensity, easy maintenance and high reliability.
Description
Affiliated technical field
The utility model relates to a kind of exterior mixing of the bi-component moment hybrid reaction of tunnel and underground engineering spray film waterproof construction that is applicable to gas spray gun.
Background technology
In the tunnel and during the spray film waterproof construction of underground engineering, need with spray regime with acrylic acid magnesium master's liquid and other auxilliary liquid moment when spraying mix, polymerization forms structural material spray film.In this work progress, because the particularity of tunnel and underground engineering needs the most coarse injustice of basal plane, humidity and the part of waterproof that infiltration or flowing water are arranged, basal plane and ground angle are again greater than 90 °.Therefore, require spraying bed thickness (be more than the 3mm) that the spray film watertight composition on this basal plane requires than other place and film forming rapidly in the construction, and can be with various humidities, have the steep basal plane of open fire to produce good the bonding.Under such working environment, to spraying tool particularly spray gun specific (special) requirements is arranged.Existing spray gun has the following disadvantages: emitted dose is not enough, because main liquid and auxilliary liquid fully do not mix, influences film-formation result; The liquid that sprays during operation is easy to generate everywhere and splashes, and influences jeting effect, and harmful; When spray suspending or finish, the many components liquid that remains in the nozzle place also can polymerization reaction take place causes the obstruction of nozzle, the proceeding of influence construction.
Summary of the invention
The purpose of this utility model provides a kind of exterior mixing that is used for bi-component moment hybrid reaction gas spray gun, and this kind spray gun film-formation result is good, and film forming is rapid, can spray to form thicker waterproof membrane, and can effectively prevent to spray splashing and the obstruction of nozzle of liquid.And this spray gun flexible operation, easy to use, labour intensity is low, maintenance is simple, reliability is high.
The utility model solves its technical problem, the technical scheme that is adopted is: a kind of exterior mixing that is used for bi-component moment hybrid reaction has gas spray gun, the nozzle that comprises removable connection on rifle body and the rifle body, its design feature is: rifle body and nozzle are provided with through-hole for auxiliary liquid along the axis, periphery around through-hole for auxiliary liquid is provided with channel for main liquid, and the anterior outside of channel for main liquid then is provided with gas passage; Specifically consisting of of this gas passage: the gas passage at rifle body place is a cavity, and gas passage then is the plural through hole that is communicated with cavity and tilts to the axis along spray nozzle front end on the nozzle.
During use, nozzle is installed on the rifle body, main liquid, auxilliary liquid and Compressed Gas are sent into from passage separately respectively by required flow and pressure.Compressed air is by the airflow hole ejection of annular spread on the nozzle, form the high speed cluster air flow, because airflow hole, the ejection air-flow with directive by the main liquid of its encirclement and auxilliary liquid, force the atomizing of main liquid and auxilliary liquid fully to mix, the assurance polymerisation was finished in moment, formed evenly, has the membrane waterproofing of adequate thickness; By the adjusting of gas flow and gas pressure, can regulate main liquid, auxilliary liquid by required atomized particle size, further guarantee the abundant polymerization of main and auxiliary liquid.Simultaneously, since gas in the periphery of main liquid and auxilliary liquid passage to spray along spray nozzle front end introversion certain angle, the angle of inclination of each airflow hole can be inconsistent, form the multilayer annular flow, main liquid, auxilliary liquid atomizing both can have been guaranteed, can form tight air-flow parcel circle to the liquid of ejection again, stop after the atomizing drop to around splash.Significantly reduced like this to operating personnel's actual bodily harm with to the destruction of surrounding environment, saved material simultaneously again.
The utility model can be replaced respective nozzles according to the requirement of sprayed construction.Different nozzles, its airflow hole is to the inclined angle and the axis length difference of central axis.Thereby the replacing nozzle, the angle of inclination difference that air-flow is sprayed, the far and near difference of injection.Thereby adjust the size of the jet face of liquid formation, change the emitted dose on the unit basal plane.As can adopt the big nozzle of inclined angle at the basal plane that water environment is arranged to strengthen the emitted dose on the unit basal plane, form thicker membrane waterproofing rapidly, realize the waterproof requirement of instant water blockoff.
Compared with prior art, the beneficial effect of the technical solution of the utility model is: because gas passage surrounds fluid passage on nozzle, and the angled inclination of airflow hole, the gas that makes ejection like this introversion forward forms the parcel circle, can guarantee that main liquid, auxilliary liquid fully mix, film-formation result is good, and film forming is rapid, can spray to form thicker waterproof membrane; Can effectively prevent to spray splashing of liquid again.
The back-connected feed tube of the channel for main liquid of above-mentioned rifle body, this feed tube side direction are connected with the rinse water passage of band valve block.
Like this, when stabilization sub stage before injection beginning and technical time-out, by the conversion of valve block, clear water in the water-dilution channel is sprayed from channel for main liquid, both isolated main and auxiliary liquid, again channel for main liquid had been cleaned, prevented that the residual of two component fluids from causing that polymerization causes spray nozzle clogging.Make that the utility model is easy to use, it is simple to safeguard, reliability is high, labour intensity is low.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
