For the ease of mobile air power source 1, air power source 1 and air operated reversing valve 7 are placed on propulsion source dolly 9.Described propulsion source dolly 9 is mainly made up of vehicle frame and four wheels that are arranged under vehicle frame, is also provided with handle in a side of vehicle frame.
On feed pipe 6, be provided with a switch handle 10 opening and closing for controlling suction gun 3, on gas-solid separating device 2, be provided with an electric cabinet 25, be provided with the wireless transmission box 11 being connected by wireless signal with electric cabinet 25 in switch handle 10 1 sides.
Be described in detail with regard to principle of work and the working process of suction gun in the present embodiment 3 and blowback washing system below:
First, open air power source 1, and the spray gun urceolus 31 of suction gun 3 is inserted in powder lot in bags, then spray gun inner core 32 is inserted to spray gun urceolus 31 internal directs to bottom.When being sucked away with back pocket internal pressure, reduces the powder of spray gun urceolus 31 inside, tonifying Qi hole 311 is mended wind generation suction pocket top is adsorbed on to spray gun urceolus 31 surfaces, form the pocket of a sealing, tonifying Qi hole 311 tonifying Qi deficiencies cause pocket inside and external pressure gap to strengthen, pressure difference is by pocket toward intermediate compression, and the powder between pocket and spray gun urceolus 31 is clamp-oned in the cavity between spray gun urceolus 31 and spray gun inner core 32 by charging hole 312 the most at last.The powder being deposited in cavity is fluidized and siphons away finally by the material sucking port 321 of punishment in advance tube 32.
After powder is siphoned away by suction gun 3, air driven powder enters gas-solid separating device 2 through feed pipe 6 by the feed check valve 21 of opening.Now, most of powder is leaked in the hopper under stay bearing plate 4 with air separation in cyclone 22 inside of gas-solid separating device 2, all the other superfine powders are intercepted by dust removal filter element 24, pure air is through connecting tube 5, enter the pipe joint 713 of air operated reversing valve 7 and gas vent 712(now, the right piston 73 of air operated reversing valve 7 is positioned at left side, passage between pipe joint 713 and gas access 711 is blocked, make air to flow to air power source 1 from gas vent 712, as shown in Figure 2), air in last air power source 1 enters into gas outlet 78(now by gas access 711 again, passage between right piston 73 and gas outlet 78 is connected), and flow in atmosphere from the gas port 781 of gas outlet 78.
In use for some time, dust removal filter element 24 stops up serious, need to clear up.Now, only need control system to 7 one instructions of air operated reversing valve, cylinder actuating mechanism will move right, drive left piston 72 and right piston 73 to move simultaneously, thereby left piston 72 is blocked the passage between pipe joint 713 and gas vent 712, passage between passage and gas access 711 and the pipe joint 713 between gas outlet 78 and the gas vent 712 in left side is connected, make the gas port 781 of outside air through left side gas outlet 78, gas vent 712, after air power source 1, enter gas access 711 and flow to pipe joint 713, finally flow to gas-solid separating device 2 through connecting tube 5.Because dust removal filter element 24 is placed in gas-solid separating device 2, when air flows to gas-solid separating device 2 when interior from connecting tube 5, the superfine powder of dust removal filter element 24 surface adhesion will be blown off and falls in the hopper under stay bearing plate 4.Now, be arranged on blowback dust discharge check valve 41 on stay bearing plate 4 in open mode, superfine powder will enter into and be attached thereto logical dust-proof water tank 8 through blowback dust discharge check valve 41.Finally, the air after dedusting enters into atmosphere.
In blowback process, be arranged on the feed check valve 21 at gas-solid separating device 2 inlet point places in closed condition, prevent from entering into suction gun 3 and entering environment through feed pipe 6 with the air blowback of superfine powder bringing dust pollution.
In the present embodiment, described air power source 1 is high pressure positive blower.Described air operated reversing valve 7 be by be arranged on wireless transmission box 11 on feed pipe 6 to be arranged on electric cabinet transmitted signal on gas-solid separating device 2 (when long during by switch handle 10, wireless transmission box 11 can be received blowback signal), then commutated to cylinder actuating mechanism transmission instruction by control system.In the time of specific works, also can timing blowback be set by electric cabinet panel, the automatic back blow several seconds after the time that system works arranges; Also can pressure difference be set by system and carry out blowback, before and after final dusting filter core, difference of pressure reaches the settings automatic back blow several seconds later.
On stay bearing plate 4, be also provided with pneumatic valve disc (not marking in figure), in the time that system is normally worked, pneumatic valve disc is in opening-wide state, and the powder in gas-solid separating device can leak in hopper via Pneumatic butterfly valve; In hopper, be provided with sensor, in the time that sensor detects in delivery duct that liquid is counter to be poured in hopper, sensor will be thought control system transmitted signal, closes pneumatic valve disc, prevents that liquid from entering in gas-solid separating device 2, damages whole system.
In the present embodiment, in order to increase safety performance, on stay bearing plate 4, be provided with an annular safety barrier 12.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention but not restriction technologies scheme, although applicant has been described in detail the present invention with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technical scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
