The utility model has the technical scheme that the nozzle device for a concrete wet-blasting machine comprises a nozzle body and a nozzle socket, wherein the inner circle surface of the nozzle body and the outer circle surface of the tail part of the nozzle body are coaxially sheathed and matched in a sliding way; the nozzle body on the matching part of the inner circle surface and the outer circle surface is provided with three annular grooves, and sealing rings are arranged in the annular grooves; a fastening connector is arranged between the port of the nozzle socket and the outer circle surface of the nozzle body, the nozzle body among the three sealing rings on the tail part of the nozzle body is provided with a circle of annular accelerating agent slot, and accelerating agent bores are uniformly distributed along the circumferential direction of the bottom of the annular groove; the nozzle socket on the corresponding direction of the annular accelerating agent slot is provided with an air inlet port, and an air inlet device is connected outside the air inlet port.
Description
Technical field
The utility model relates to a kind of concrete spraying machine, especially relates to a kind of concrete spraying machine spray nozzle device.
Background technology
Along with applying of concrete spraying support, concrete spraying machine is widely used in national defence cave depot and railway, highway, reaches the quick repairing of the tunnel culvert of water conservancy.The concrete that mixer stirs is sent concrete into wet shot machine carrier pipe by pumping installations and is arrived nozzle, finally adds accelerator at the nozzle place, by compressed air the head of concrete from nozzle is ejected.
At present, the spray nozzle device that concrete spraying machine is used is to be peeled off by concrete to break up chamber, eddy flow cavity and sprayer body and constitute, break up chamber and eddy flow cavity and be provided with three compressed air inlet pipes, existing spray nozzle device is complex structure not only, be difficult for mounting or dismounting fast, and not having the accelerator inlet, three compressed air inlet pipes can't evenly mix gas, concrete, accelerator, can't realize that long distance injection adds the concrete of accelerator.
Summary of the invention
The purpose of this utility model is in order to overcome existing defective, to provide a kind of simple in structure, gas, concrete, accelerator evenly can be mixed, realizing that long distance injection adds the concrete spray nozzle device of accelerator.
The purpose of this utility model is to realize like this, a kind of concrete spraying machine spray nozzle device, comprise nozzle body and nozzle carrier, it is characterized in that, coaxial line slip sleeve cooperates between nozzle carrier inner headed face and the nozzle body afterbody periphery, on both cooperate partly nozzle body, three cannelures are arranged, sealing ring is housed in the groove, be provided with between nozzle carrier port and the nozzle body periphery and be fastenedly connected device; Have the annular accelerator groove of a circle on the nozzle body in the middle of nozzle body afterbody three sealing rings, be evenly equipped with the accelerator hole along cannelure bottom circumferencial direction, with the nozzle carrier of annular accelerator groove correspondence position on be provided with air inlet, air inlet connects inlet duct outward.
Concrete enters nozzle from the nozzle carrier afterbody in the utility model, and compressed air and accelerator enter nozzle by inlet duct, because accelerator trench bottom circumferencial direction is evenly equipped with the accelerator hole, accelerator passes through after being compressed air atomizing
Uniform accelerator hole enters in the concrete uniformly in the nozzle body afterbody cannelure, gas, concrete, accelerator evenly mix, make concrete arrive rapid solidification behind the working face, resilience reduces, and has avoided simultaneously stopping up the air inlet aperture because of sealing ring damages gas leakage, the leakage accelerator that brings and leaks concrete.
Be fastenedly connected device between described nozzle carrier port and the nozzle body periphery, can be set to: on the nozzle carrier port, be provided with radial flange, on the nozzle body periphery with on the corresponding position of nozzle carrier port radial protrusion is set, radial flange and radial protrusion are fastenedly connected.
Described inlet duct can be: a four-way air inlet pipe, its first mouth of pipe is a compressed air inlet port, on air inlet stop valve, air inlet snap joint are housed; Second mouth of pipe accelerator inlet, on connect a reverse flow check valve and accelerator snap joint; The 3rd mouth of pipe is gas vent, is connected to vent valve.
The reverse flow check valve is set in the accelerator inlet, has avoided refluxing because of the plugging accelerator.The air inlet stop valve is housed on the compressed air inlet port, and gas vent is connected to the venting ball valve, during the dismounting nozzle, closes stop valve, opens vent valve, is discharged into the pressure in the device of air, can avoid gas material concrete to hurt sb.'s feelings.
The utility model is simple in structure, gas, concrete, accelerator evenly can be mixed, and realizes that long distance injection adds the concrete of accelerator
