A method of using the spray painting device for centrifugal pump processing according to any one of claims 1 to 4, characterized in that it includes the following steps:

S1. When using, the user pre-fills the card holder (7) with some paint, and then the user places the centrifugal pump body (8) in the card holder (7). At this time, the user turns on the first water pump ( 4) and the motor (10), and preset the reciprocating stroke of the motor (10). At this time, the first water pump (4) moves the paint in the storage tank (3) through the suction pipe (5) and the elbow (6) It is transferred to the telescopic tube (15), and then transferred to the square box (14) via the telescopic tube (15), and then transferred to the hollow shaft (13) via the square box (14), and the paint is sprayed out through multiple sets of nozzles. , spray paint the centrifugal pump body (8), and the motor (10) can drive the connecting vertical plate (11) and the fixed shaft (12) to swing, so that the hollow shaft (13) can drive the nozzle to swing, and then the centrifugal pump can be sprayed. The pump body (8) is spray-painted in all directions;

S2. Paint mist will be formed during the painting process. At this time, the user turns on the first exhaust fan (1716) through the controller. The first exhaust fan (1716) will pass the paint mist formed in the spray paint room (1) through the connecting pipe. (172), fixed pipe (173), connecting pipe (174) and L-shaped pipe (177) are quickly transferred to the mist outlet pipe (178). At the same time, the user turns on the second water pump (1713), and the second water pump (1713) The clean water in the water collection tank (2) can be transferred to multiple sets of ring pipes (1711) via the T-shaped pipe (1714) and the connecting frame (1715), and then sprayed out through multiple sets of water spray pipes (1712). The water curtain formed by spraying clean water from the set of water spray pipes (1712) sprays and settles the paint particles in the paint mist step by step. At the same time, the filter cartridge (179) and the first activated carbon filter plate (1710) can remove the formed paint particles. Capture to facilitate centralized processing in the later stage and avoid random discharge of paint from affecting the surrounding environment;

S3. When the fixed shaft (12) swings at the same time, it will synchronously drive multiple sets of arc-shaped stirring plates (16) to swing, continuously stirring the paint in the storage tank (3) to avoid paint precipitation, and at the same time, the third An exhaust fan (1716) draws the purified gas so that the gas can be quickly discharged through the exhaust pipe (22). If it is necessary to clean the filter cartridge (179) and the first activated carbon filter plate (1710), the user The user only needs to turn the threaded sleeve (19) to drive the connecting pipe (174) to move toward the back until it is out of contact with the fixed pipe (173), and then the user turns the sealing cover (176) to separate it from the treatment tank (175) , the filter cartridge (179) and the first activated carbon filter plate (1710) can be taken out together from the treatment tank (175), and then the user rotates the first activated carbon filter plate (1710), and the first activated carbon filter plate (1710) can be removed. 1710) is taken out from the filter cartridge (179) to facilitate the user to clean the paint particles in the filter cartridge (179) and the first activated carbon filter plate (1710).
