Compared with the prior art, the spray head has the advantages of uniform mixing, low resilience rate and less dusts on working face.
Description
Technical field
The utility model relates to a kind of pulp shooting machine and uses shower nozzle, be specially a kind of have usefulness pulp shooting machines such as the colliery of stirring and quickening function, mine, water conservancy, tunnel appurtenances---pulp shooting machine is used shower nozzle.
Background technology
The pulp shooting machine of present underground mine use; Generally to be jetting material (amalgam of cement, stone, sand, powder accelerator) deliver to shower nozzle from the pulp shooting machine main frame through conveyance conduit with wind adds water and mixes; Be ejected into again and receive spray plane, have the efficient height, the advantage that fed distance is far away.
But the following shortcoming of also bringing simultaneously: jetting material mixes inhomogeneous, and rebound degree is high, and its waste that brings is also high, and the work plane Dust Capacity is big, serious harm operator healthy.
Cause above most important reason to be the unreasonable structure of pulp shooting machine shower nozzle, backward in technique.
Summary of the invention
For addressing the above problem; The utility model provides a kind of pulp shooting machine to use shower nozzle; The utility model is provided with mixing assembly and wind accelerator in order between water spray assembly and jet blower, when possessing above-mentioned advantage, can reach mix, rebound degree is low, the work plane dust is little effect.
For achieving the above object the following technological means of the employing of the utility model:
A kind of pulp shooting machine is used shower nozzle; Comprise jet blower and the water spray assembly that is connected with defeated material sebific duct, the water spray assembly end of said shower nozzle is connected with mixing assembly, is provided with stirring vane in the described mixing assembly; The end of mixing assembly connects the wind accelerator, and the other end of wind accelerator connects jet blower.
Above-mentioned shower nozzle: mixing assembly comprises stirring pipe, is provided with helical mixing blade in the stirring pipe.
Above-mentioned shower nozzle, said wind accelerator is the spiral wind accelerator, is provided with the spiral duct towards the whitewashing direction in the accelerator.
Above-mentioned shower nozzle, described wind accelerator comprises pipe box, and the pipe box inwall is communicated with, and outer wall is communicated with high-pressure air hose.
Above-mentioned shower nozzle, wind accelerator front end is the convergent shape, the convergent direction is identical with the whitewashing flow direction.
Above-mentioned shower nozzle, mixing assembly and wind accelerator are integrated; Be provided with helicoid in the said jet blower, said helicoid is fixed on the jet blower inwall; Said mixing assembly and wind accelerator two ends are provided with flange, and an end connects the water spray assembly, an end connects shower nozzle.
The operating principle and the beneficial effect of the utility model show:
The utility model is provided with mixing assembly and wind accelerator between water spray assembly and water spout, the wind accelerator is positioned at the mixing assembly rear portion, after accomplishing stirring, quickens again, and agitator adopts helical mixing blade.The jetting material of doing that the pulp shooting machine conveyance conduit is sent here with wind has been realized mixing the first time of material and water behind the water spray assembly, forms wet feed, unmixed good water, the amalgam of siccative.
Amalgam arrives the helical stir assembly forward, and the amalgam of wet feed, unmixed good water, siccative mixes the effect that makes them become Wet-type patching machine fully and arrived once more under the effect of helical mixing blade.
Mixed material arrives the wind accelerator more forward, and jetting material wet under the effect of accelerator has increased kinetic energy, and spouting velocity is improved, the material that makes ejection receive on the spray plane bonding more firm, thereby reduced rebound degree.
Be provided with helicoid in the said jet blower, next mixed material arrives jet blower more forward behind accelerator, and helix on the jet blower and convergent centrum make the wind of spiral wind accelerator and wet jetting material mix more even.
Mixing assembly and wind accelerator are integrated; Said mixing assembly and wind accelerator two ends are provided with flange, and an end connects shower nozzle, an end connects the water spray assembly, are convenient to realize the transformation to existing shower nozzle; Between former water spray assembly and water spout, add this integral structure and get final product, it is convenient to transform.
