Accompanying drawing explanation
For ease of explanation, the present invention is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is that a kind of shotcrete pipe high pressure for fiberboard of the present invention quantitatively saves adhesive process flow chart;
Fig. 2 is striker high pressure nozzle of the present invention and steam jet structural representation.
The specific embodiment
As depicted in figs. 1 and 2, a kind of shotcrete pipe high pressure for fiberboard of the present invention quantitatively saves adhesive process, by high voltage power mixing arrangement 6, high voltage power pump 5, high steam shotcrete pipe size applicator 17 forms, described high voltage power mixing arrangement 6 inputs are provided with glue import 1, water inlet 2, reserved agent import 3 and the first compressed air inlet 7, described high voltage power mixing arrangement 6 outputs are connected with high voltage power pump 5 inputs, described high voltage power pump 5 is externally connected to the second compressed air inlet 8 and hot water cleans import 4, described high voltage power pump 5 outputs connect high steam shotcrete pipe size applicator 17.
Wherein, described high voltage power mixing arrangement 6 is mainly comprised of high-pressure pump, micrifying apparatus, filter, high-pressure flowmeter and compressed air pump.
Described high voltage power pump 5 is mainly comprised of high-pressure pump, air pressure pump and hot water scavenging pump.
Described high steam shotcrete pipe size applicator 17 mainly cleans import 4, applying glue pipe 9, the first compressed air inlet 7, the second compressed air inlet 8, vapours import, condensate water device 13 and drying machine 12 by striker high pressure nozzle 14, steam jet 15, hot water and forms.Between described striker high pressure nozzle 14 and steam jet 15, be provided with glue spraying pipe 11.
Described applying glue pipe 9 is provided with mixed glue solution import 10, and described mixed glue solution import 10 is connected with high voltage power pump 5 outputs.
During use, by the micrifying apparatus in high voltage power mixing arrangement, oarse-grained impurity such as urea etc. can be smashed to molecule, filtration through filter, the glue of spurting into nozzle is fine and smooth small glue and drips, thereby avoided the obstruction of nozzle, improved the fogging degree of glue, thereby glue and fiber are mixed more uniformly in shotcrete pipe the inside and saved resin added.By compressed air bucking-out system is set, in this process, compressed air enters filter, more efficiently glue is carried out to isolated by filtration.The high pressure conditions that glue is directly promoted to 100-200 bar by high voltage power system is spurted into shotcrete pipe, and has replaced the injection of using high steam, the increase of having saved steam consumption and following drying cost.By high voltage power system, compressed air is set high-pressure pump is played to good control and compensating action, reduce the load of high-pressure pump, extend the service life of high-pressure pump, be more conducive to the control of pressure limit.Counterpart place at high pressure striker nozzle arranges steam jet, and the flow of steam sprays according to the flow of fiber in applying glue pipe, realizes the pneumatic nebulization of fiber, and applying glue to fibers is more even.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
