Description
Technical field
The present invention relates to a kind of pitch flusher in flexible pavement construction construction, specifically is that a kind of pitch with cleaning sprays transport.
Background technology
Because present its bitumenpump of distribution vehicle all is installed in the outside of pitch case, each starting all must be heated bitumenpump, not only wastes time and energy, and influences construction quality, and has potential safety hazard.Prior art is such as device shown in Figure 1; When pitch sees that stop valve 3, pitch spray that stop valve 5 is opened off and oil return stop valve 8 when closing; When starting bitumenpump 4; The liquid liquid of hot melt is blue or green just from 1 sucking-off of heated bitumen case, sees stop valve 3, bitumenpump 4, first threeway 10 and pitch off through fuel sucking pipe 2, pitch and sprays stop valve 5, is sprayed onto the road surface from Asphalt-distributing spray head 6 and gets on.When needs suspend sprinkling, just close pitch and spray stop valve 5 and open oil return stop valve 8 simultaneously; Under the effect of bitumenpump 4, just through first threeway 10, first oil return pipe 7, the oil return stop valve 8 and second oil return pipe 9 pump in the heated bitumen case 1 the hot melt liquid bitumen.When construction operation finishes; Then close pitch earlier and see stop valve 3 and oil return stop valve 8 off; Open pitch and spray stop valve 5; Bitumenpump 4 remains in operation a little while, with in the pump with pipeline in delayed heat liquation attitude pitch from Asphalt-distributing spray head 6, spray, the hot melt liquid bitumens of making every effort to bitumenpump 4 is interior are got rid of totally fully and are shut down.This form of structure has a very big defective, after device is finished the work, though do one's utmost to remove hot melt liquid bitumen in the bitumenpump, always has small amount of thermal liquation attitude pitch to remain in the bitumenpump, condenses after the cooling, and freezing bitumenpump can not rotate.
For addressing this problem; On December 19th, 2007; China utility model patent notice of authorization CN 200992674Y discloses a kind of asphalt distributor, is on body, to be provided with asphalt oil tank, diesel fuel tanks, tee pipe coupling, bitumenpump and manual electric spray gun, and the efferent duct that coal tar is irritated and the efferent duct of diesel fuel tanks are connected with two imports of tee pipe coupling through valve respectively; The outlet of tee pipe coupling is connected with the input of bitumenpump, and the output of bitumenpump is connected with manual electric spray gun; Clean the anti-effect of condensing of bitumenpump though this device plays, what clean bitumenpump is directly to wash with diesel oil.
Equally; The asphalt pavement maintanance truck mulseal flusher that on September 29th, 2010, Chinese utility model patent notice of authorization CN 201593153 U were opened; Comprise mulseal heater incubator, ball valve, filter, tee ball valve, bitumenpump, pneumatic hose, spray gun, one way valve, washing oil case; This device also is to adopt diesel oil through the conversion of control tee ball valve, directly washes bitumenpump.Same diesel consumption is big, and use cost is high.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of pitch with cleaning to spray transport; During this device work; Can clean remaining pitch in the bitumenpump easily; Make bitumenpump after cleaning, always be in a kind of state that can freely start, the pitch after can not being cooled congeals, and avoids naked light to bake unsafe way generations such as bright.Use cost is low simultaneously.
The technical scheme that the present invention adopted is: a kind of pitch with cleaning sprays transport, comprises that heated bitumen case 1, pitch sees stop valve 3, bitumenpump 4, pitch off and spray stop valve 5, Asphalt-distributing spray head 6, oil return stop valve 8, diesel fuel tanks 11 and diesel oil stop valve 13; Said heated bitumen case 1 is through fuel sucking pipe 2; Seeing stop valve 3 off through pitch is connected with second tee piece, 14 joints; The outlet of second tee piece 14 is connected with the input of bitumenpump 4, and first threeway 10 of the output warp of bitumenpump 4, pitch sprinkling stop valve 5 are connected with Asphalt-distributing spray head 6; Described bitumenpump 4 and oil return stop valve 8 and first oil return pipe, 7, the second oil return pipes, 9, the first threeways, 10, the second tee pieces 14, and diesel oil clean cycle pipe-line system of the 3rd tee piece 15 common compositions; Diesel fuel tanks 11 connects described the 3rd tee piece 15 through diesel oil carrier pipe 12; Described diesel fuel tanks 11 is casings that a volume 8-12 rises.
Beneficial effect of the present invention: this device can realize that the pitch in the flexible pavement construction construction sprays conveying immediately, and the work back is convenient to be cleaned, and guarantees that pitch sprays quality; Make bitumenpump after cleaning, always be in a kind of state that can freely start; At any time can start, the pitch after can not being cooled congeals, and avoids naked light to bake unsafe way generations such as bright; Alleviate manipulation strength, increase work efficiency.So the each cleaning of the present invention always lets a small amount of diesel oil in the diesel fuel tanks flow in the bitumenpump, and the residual bitumen in the bitumenpump is dissolved among the diesel oil, can not waste diesel oil, can use continuously, and the while use cost is low.
