Among the figure: the paint can of the built-in agitator of 1-, 2-air pressure pump, 3-paint filter, 4-pressure maintaining valve, 5-pneumatics automatic spray gun, 6-magnetic valve, 7-check valve, the 8-pressure regulator valve, 8-1-pressure regulator valve a, 8-2-pressure regulator valve b, the 9-pressure regulator valve that atomizes, 10-striker pressure regulator valve, 11-air filter, 11-1-air filter a, 11-2-air filter b, 12, the prime magnetic valve, 12-1-prime magnetic valve a, 12-2-prime magnetic valve b.
The specific embodiment: with reference to Fig. 1,2, this spray equipment is installed in the top that nitrogen seals, and it is that the donut at center becomes miter angle to be evenly distributed that eight automatic spray guns wind with oxygen rifle work centre, and this utility model mainly comprises following components:
(1) vanish system:
Coating is contained in the paint can 1 of built-in agitator, the pneumatic drive mechanism and the air pressure pump 2 of agitator are installed on the bucket, driving by agitator prevents that the coating in the tube from precipitating, guarantee the uniformity of paint ingredient, coating is under the effect of air pressure pump 2 uniformly, behind paint filter 3 and check valve 7, flow to pneumatics automatic spray gun 5, automatic nozzle is led in an outlet of two fens valves in the pneumatics automatic spray gun 5, loop pipe is led in another outlet, and the coating in the loop pipe flows back to the paint can 1 of built-in agitator behind pressure maintaining valve 4.
(2) pneumatic circuit
The system pressure of the pneumatic circuit of this device is 0.5Mpa, mainly be divided into two parts: a part is behind air cleaner 11-1, flow to pressure regulator valve 8-1 and 8-2, after decompression, flow into two-position three way prime magnetic valve 12-1 and 12-2 respectively, gas behind magnetic valve 12-1 flows into the driving mechanism of agitator, and the gas behind magnetic valve 12-2 flows into air pressure pump 2; Another part flows to eight atomizing pressure regulator valves 9 respectively behind air cleaner 11-2, the gas that comes out from atomizing pressure regulator valve 9 is divided into two-way, one the road flows to the nozzle of pneumatics automatic spray gun 5, atomize to being used for the coating that oxygen lance spraying is coated with, another road flows to striker pressure regulator valve 10, flow to two-position three way magnetic valve 6 through the post-decompression gas of striker pressure regulator valve, by the action of magnetic valve 6, the outlet of determining two fens valves is to connect with nozzle or connect with loop pipe.
(3) control loop
Control loop is mainly used in must be controlled magnetic valve, and its voltage is 24V, and electric current is 20A.When prime magnetic valve 12-1 gets when electric, air-flow enters agitator executing agency, the agitator action; When prime magnetic valve 12-2 gets when electric, air-flow enters air pressure pump 2, and coating is exported in the compression pump action; When magnetic valve 6 dead electricity, air-flow flows to two fens valves of pneumatics automatic spray gun 5, promotes to move behind the piston, and valve was connected with nozzle in two minutes, and the formation under the effect of atomizing source of the gas of the coating of flow nozzle is vaporific, carries out spraying operation; When magnetic valve 6 when electric, cut off source of the gas, piston moves forward under the back-pressure effect of spring, and nozzle is closed, valve was connected with loop pipe in two minutes, the two fens interior coating of valve flows back to the paint can 1 of built-in agitator behind pressure maintaining valve 4 from loop pipe.Major spare part sees the following form:
