[0030] Such as Figure 1 to Figure 6 As shown, the method for preparing a supported zinc oxide photocatalyst of the present invention includes the following steps:
[0031] S1: Weigh the raw materials in parts by weight: 30-50 parts of zinc nitrate hexahydrate, 5-10 parts of polyethylene glycol stearate, 15-20 parts of thiourea, 5-10 parts of red mud, 1 part of cobalt carbonate -2 parts and 10-15 parts of kaolin;
[0032] S2: Add zinc nitrate hexahydrate to the ultrasonic generator, add absolute ethanol to dissolve, then add sodium hydroxide solution to adjust the pH to 12-13, and continue to sonicate for 20-30 minutes at a frequency of 40-60KHz to obtain a suspension M;
[0033] S3: Add thiourea to the stirrer, then add an appropriate amount of water and stir to dissolve it to obtain suspension N;
[0034] S4: Pour suspension N into an ultrasonic generator equipped with suspension M, then add polyethylene glycol stearate, and continue to sonicate at a frequency of 40-60KHz for 30-6...
Example Embodiment
[0038] As an embodiment of the present invention, a set of rollers 3 arranged in parallel are provided in the cylinder 1, and the rollers 3 are rotatably connected to a fixed frame 31 in the cylinder 1. The rotating shaft on the side of the roller 3 Gears 32 meshing with each other are fixedly connected; one of the rollers 3 shaft is fixedly connected with a gravity ball 33 through a rigid rod; when the cylinder 1 rotates, the gravity ball 33 drives the roller 3 to rotate under the action of gravity, and the two rollers 3 Speed up the crushing speed of the raw materials in the cylinder 1 after rotation, and further increase the grinding and crushing efficiency of the ball mill; when the raw materials are rotated and ground in the cylinder 1, when the cylinder 1 rotates, the gravity ball 33 always maintains a drooping state under the action of gravity , The gravity ball 33 drives the roller 3 to rotate through a rigid rod, and the two rollers 3 rotate together through a gear 32...
