Description
Technical field
The present invention relates to sander pipe of locomotive technical fields.
Background technique
The stucco system of locomotive is the important component of locomotive, is played to the adhesion coefficient and safe operation that improve locomotive
Vital effect.The process of railway locomotive stucco at present is that the wind of locomotive main air reservoir enters stucco unit by blast pipe and blows
Sand in stucco unit makes sand roll in stucco unit agitation, into stucco unit sand export and then along sand pipe
It flows between wheel track, plays the role of increasing wheel-rail friction power.Also often there are various problems in stucco system simultaneously, such as: sand
Son blocking blast pipe；Sand is had after stucco to remain in sand pipe out, is easy to keep sand hardened in rain and snow, is blocked
Sand pipe causes stucco system can not work normally out, has seriously affected the operational safety of locomotive.
Existing scheme is that cylinder stops air feed stucco stopping, when stopping air feed due between stucco unit and air inlet pipeline
There are pressure difference, sand easily passes through air outlet suck-back and enters air hose, and is easy Relict Sand when air feed stopping in sand pipe, leads
Cause stucco blockage.
1) the easy suck-back of sand enters blast pipe or blocking air outlet when existing stucco unit blowing stops, and leads to not again
Secondary stucco.
2) air feed stops after stucco, has sand and remains in sand pipe, is easy to make remaining sand in rain and snow
Daughter board knot, blocking sand pipe cause stucco system can not work normally.
3) existing stucco unit sand subflow amount, flow velocity are smaller.
Summary of the invention

Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
The present invention is as a kind of completely new stucco unit, as shown in Fig. 2, wind regime air inlet 4 is divided to for two stucco wind paths, one
Transportation work style stirs sand tuyere 2 by anti-suck and anti-suck blast tuyere 3 carries out stirring sand and blast, flows to sand through sand export 8 and takes turns
Between rail, another transportation work style enters energy storage device 6 through energy storage air inlet 5, and after energy storage device is filled with gas, gas is from energy storage outlet air
Mouth 7 enters sand export 8, makes gas flow rate quickening pressure at sand export reduce to form siphon, sand flow and flow rate increases, stucco
It is more smooth；Wind regime stops air feed when stucco stops, and energy storage device releases the gas of storage, blows to and shake out through energy storage air outlet 7
Mouth 8, sand remaining in sand pipe is blown away, and it is anticlogging to play the role of cleaning sand pipe.
Sand tuyere 2 is stirred in anti-suck of the present invention and anti-suck blast tuyere 3 is provided with anti-block apparatus and avoids sand reflux blocking
Blast pipe；As shown in Fig. 2, tuyere is anti-down suction nozzle, it is set with high-performance elastic set 23 outside tuyere 21, wind when pipeline air feed
Blowing resilient sleeve along tuyere air outlet 22, deformation occurs, and then tuyere is flowed out in gap of the wind between resilient sleeve and tuyere outer wall,
Air feed stops resilient sleeve and stops deformation, is tightly attached to tuyere outer wall and plays the role of blocking tuyere air outlet 22, prevents in sandbox
Sand sucks tuyere air outlet, effectively avoids tuyere and air inlet blockage.
As shown in figure 3, tuyere uses variable cross-section contraction type nozzle at sand export 8, the gas circuit of the nozzle in vertical direction with
60 ° of angles and nozzle air inlet 81 are big, gas outlet 82 is small, and the flow velocity after the variable nozzle of the gas in energy storage device increases,
Make pressure at air outlet 82 reduce to form siphon, makes the outflow sand pipe that sand is more smooth.Wind regime stops energy storage when air feed and fills
Setting the gas for releasing storage can make remaining sand cleaning in sandpipe more thorough after the nozzle.
Energy storage device 6 is as shown in figure 4, be elevated pressure plenum road, air outlet 3 65 between gas outlet 1 and gas outlet 2 62
It is pressure release ventilating duct between air outlet 2 62.When stucco works, a part of wind regime is pushed away through energy storage air inlet 5 into air inlet 64
Dynamic activity wind locking 63 enters energy storage device, and pressure is gradually increased in energy storage device, gradually rises piston 66 and spring 67, piston
When moving to gas outlet 1, spring, piston and energy storage device chamber pressure reach equilibrium state, as shown in figure 4, wind is by going out
Port 1 and gas outlet 2 62 are flowed out through energy storage air outlet 7, into sand export 8, wind regime flow velocity at sand export are made to accelerate pressure
Reduction forms siphon, and sand flow velocity improves at sand export, shakes out more smooth.Wind regime stops air feed, movable wind locking at the end of stucco
63 close, and gas outlet 3 65 is exposed, as shown in figure 5, the gas in energy storage device is by air outlet 3 65 then through air outlet two
62 outflows, pressure is gradually reduced in energy storage device, and spring pushes piston 66 slowly to decline, it is distinguished and admirable go out after through energy storage air outlet 7 into
Enter the sand export 8 with variable nozzle, sand remaining in sand pipe blown out into sand pipe, plays the role of clearing up sand pipe,
Prevent stucco blockage.
Spring rate K, piston floor space S, piston and spring weight G, piston stress when piston motion is to air outlet 1
Balance, amount of spring compression X, pressure P=(G+KX)/S in air accumulator, it is slightly less than wind regime wind pressure, is set with this when equilibrium state
Meter spring rate can make energy storage device store gas as much as possible.
The present invention devises auxiliary blast pipeline at sand export, makes in sand pipe as a kind of completely new stucco unit
Sand flowing is more smooth；Energy storage device can clear up the residual sand in sand pipe after stucco stopping automatically；Energy storage device
Inner spring rigidity rationally designs, and guarantees the maximum amount of gas of storage in energy storage device, and contraction type nozzle is equipped at sand export,
Air velocity is increased, cleans sand grains more thorough, prevents stucco blockage；It stirs sand and blast tuyere is provided with anti-suck dress
It sets, effectively prevent sand reflux blocking blast pipe.
