The wet concrete ejection assembly comprises an extrusion pump, a concrete mixer, and a gas material mixing chamber which is provided with an air inlet, a material inlet and a material outlet. The extrusion rubber hose inlet in extrusion pump is communicated with the outlet of concrete mixer. The air inlet is communicated with compressed air. The material outlet is communicated with a material conveying pipe. The material outlet of extrusion pump is communicated with a conveying pipe, and the other end of conveying pipe is communicated with the material inlet of gas material mixing chamber. The material inlet distance (length of conveying pipe) between the material outlet of extrusion pump and the gas material mixing chamber is in the distance area which can be pumped by the extrusion pump.
Description
Technical field
The utility model relates generally to underground construction (especially under the coal mine) wet type concrete support construction equipment, specifically, is the wet concrete sprayer group.
Background technology
Wet-spray technique is a concrete spraying technique of new generation, can well control quality of concrete, reduces concrete springback capacity when spraying, and improves raw-material utilization rate, reduces the engineering construction cost; The dust that produces in the time of can effectively reducing sprayed construction is compared face dust concentration and is significantly reduced with dried, tide spray, thereby can well protect the healthy of worker, especially has bigger using value under coal mine.
In current domestic every engineering construction, the realization of concrete spraying technology is generally effectively made up by spraying machine and the supporting concrete batch plant in back (mixer) and is finished, promptly compound (sand, stone, cement) and Admixture and water must be carried out proportioning, make concrete slump reach the requirement that to spray by the mixer stirring, then concrete is flowed to concrete sprayer by certain mode, by spraying machine transmission and concrete transmission is ejected into and is subjected to spray plane.The wet shot machine that in the various wet shot machines with the extrusion pump is core is relatively simple for structure relatively, operates easy care well.
Concrete sprayer must need matching used with it concrete mixer, and both are indispensable.The wet concrete sprayer group of present extrusion pump formula comprises accelerating admixture adding set, extrusion pump, concrete mixing plant, air inlet port is arranged, the gas material mixing chamber of charging aperture, three interfaces of discharging opening; Extruding sebific duct import in the extrusion pump is communicated with the outlet of concrete mixing plant, and the extrusion pump discharging opening connects charging aperture, and air inlet port connects compressed air, and discharging opening connects the conveying pipeline road.
Utilize the compressed air delivery concrete, have characteristics simply and easily, but its fed distance is shorter, the scope of application is subjected to certain restriction.
Summary of the invention
What the utility model solved is the relatively shorter problem of existing wet concrete sprayer group delivering concrete distance, and the wet concrete sprayer group that a kind of delivering concrete distance is long, be applicable to coal mine operation is provided.
This wet concrete sprayer group comprises extrusion pump, concrete mixing plant, air inlet port is arranged, the gas material mixing chamber of charging aperture, three interfaces of discharging opening; Extruding sebific duct import in the extrusion pump is communicated with the outlet of concrete mixing plant; Air inlet port connects compressed air, and discharging opening connects the conveying pipeline road; The extrusion pump discharging opening connects carrier pipe, the charging aperture of another termination gas material mixing chamber of carrier pipe, extrusion pump discharging opening to the charging aperture of gas material mixing chamber distance (delivery tube) in the pumpable distance range of extrusion pump.
We know, if the extrusion pump discharging opening is directly received the charging aperture of gas material mixing chamber by compressed air delivery, the delivering concrete distance is shorter.And the utility model just is transported to gas material mixing chamber with concrete by the carrier pipe of length in the pumpable distance range of extrusion pump by extrusion pump, by compressed air concrete is carried again, accomplish pumping and combining that wind send, increased the distance of transmission and concrete transmission.
For above-mentioned wet concrete sprayer group, it also comprises the accelerating admixture adding set; The outlet on conveying pipeline road is connected with a import in the spray gun that two imports are arranged; Another import of spray gun connects the outlet of accelerating admixture adding set.The accelerating admixture adding set is a prior art.
For above-mentioned wet concrete sprayer group, concrete mixing plant is the horizontal mixing plant of single shaft preferably, with low material loading height, alleviates artificial material loading intensity.The horizontal mixing plant of single shaft belongs to prior art, for example, the horizontal mixing plant of single shaft comprise material is stirred, be arranged on the stirring vane on the horizontal shaft.
