As shown in fig. 2 and 6, the mixing block 51 comprises an inner layer sleeve 511, an outer layer sleeve 512 and a mixing wheel 513, wherein the inner layer sleeve 511 is installed inside the outer layer sleeve 512, the outer layer sleeve 512 is rotatably connected with the inner layer sleeve 511, one end of the outer layer sleeve 512 is fixedly connected with one end of the air inlet pipe 2 far away from the purification unit 1, the other end of the outer layer sleeve 512 is fixedly connected with the atomizing nozzle 52, the mixing wheel 513 is installed inside the inner layer sleeve 511, and a plurality of circulation holes are arranged on the mixing wheel 513. When paint is mixed with air flow and enters the mixing block 51, the blades obliquely arranged on the mixing wheel 513 are driven by the air flow to rotate. More paint can concentrate on the pipeline the latter half under normal conditions, and mixing wheel 513 rotates and to roll up the paint of concentrating on the pipeline the latter half, and paint can follow the runner hole that sets up on mixing wheel 513 when rotating along with mixing wheel 513 and throws away, and inside paint can enter into atomizer 52 with more even distribution state at the in-process of rotatory throwing, atomizer 52 spun paint spraying also become more even.
The working principle of the invention is as follows: inside compressed air enters into purifying box 11 from air inlet joint 12, the metal ball can rise under the electric field force effect, then under electric field force and wind power, the metal ball can be thrown along the arc shape face at the straight chamber 16 top of air current, under the condition of throwing speed diverse, the metal ball can be in the straight chamber 16 of air current of chaotic dispersion, tiny flying dust can gather on the metal ball surface in the air current, can slide down along fall-back sieve 15 after the flying dust is collected to the metal ball, the metal ball rolls in fall-back chamber 17, the adsorbed impurity on metal ball surface can change and adsorb on fall-back sieve 15, can roll back again between electrode plate 14 after the metal ball takes off impurity. When the air flow passes through the air inlet pipe 2 at a high speed, a negative pressure is generated at the opening of the paint outlet pipe 33, at the moment, the sensor arranged on the control valve in the paint outlet pipe 33 senses that the air pressure is reduced, the control valve is opened, the paint in the temporary storage box 31 is pumped out, in the process of pumping out the paint, the impeller 321 is driven by wind power to rotate, the impeller 321 drives the driving bevel gear 323 to rotate, the driving bevel gear 323 drives the driven bevel gear 324 to rotate, the driven bevel gear 324 drives the stirring rod 325 to rotate, and the stirring rod 325 uniformly stirs the paint. The mixing block 51 causes the paint to be more evenly distributed as it is mixed with the rapid air flow entering the mixing block 51, the evenly distributed paint being ejected with the rapid air flow through the atomizer head 52. When the painting is finished, the supporting spring 44 will rebound, the pressure of the air inside the annular air bag 41 will be reduced, the external air will be sucked into the annular air bag 41, and the instant suction force can suck the paint remained in the painting process into the annular air bag 41.
