DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer toFigures 1 to 4 , the utility model provides a Fenton oxidation device for pharmaceutical sewage treatment, which includes a tank body 1 and a conveying pipeline 2 connected to the bottom of the tank body 1. The side of the tank body 1 is tangentially communicated with a water inlet end 6. Sewage enters the tank body 1 through the water inlet end 6, and then an appropriate amount of catalyst and hydrogen peroxide are conveyed into the tank body 1 to generate strongly oxidizing hydroxyl groups to oxidize the organic matter in the water, achieving the purpose of purifying water. A fixing rod 7 is arranged in the tank body 1, and the fixing rod 7 is connected with a stirring mechanism 8.

[0021] The conveying pipeline 2 includes a plurality of S-shaped pipelines and a plurality of flanges. Adjacent S-shaped pipelines are connected by flanges. The conveying pipeline 2 prolongs the reaction time and achieves the purpose of full purification. When a certain section of the S-shaped pipeline is damaged, the corresponding flange can be loosened by using tools, which is convenient for installing a new S-shaped pipeline, and the operation is simple and convenient.

[0022] The bottom of the tank body 1 is connected with a liquid discharge end 5, and the liquid discharge end 5 is connected with the end of the conveying pipeline 2.

[0023] The stirring mechanism 8 includes three stirring blades 9, a connecting sleeve 10, a spring 11, and a spring seat 12. The stirring blades 9 are connected to the connecting sleeve 10, the connecting sleeve 10 is movably connected to the fixing rod 7, the spring seat 12 is fixed to the fixing rod 7, the spring 11 is sleeved on the fixing rod 7, and both ends of the spring 11 are connected to the connecting sleeve 10 and the spring seat 12. Due to the tangentially arranged water inlet end 6, sewage tangentially enters the inner wall of the tank body 1 from the water inlet end 6, forming a downward swirl of the sewage, which can drive the rotation of the stirring blades 9, facilitating the stirring operation of the sewage. And the eddy current has a vertically downward component force acting on the stirring blades 9, so that the spring 11 is compressed, and the stirring blades 9 move downward while stirring. When the spring 11 is compressed to a certain position, the stirring blades 9 can be pushed up, that is, the stirring blades 9 swing up and down while rotating, achieving the purpose of full stirring, further strengthening the reaction effect, replacing the traditional stirring method of driving the stirring head to rotate by a motor, reducing the maintenance cost and relatively complex installation steps, and being safe and reliable.

[0024] The connecting sleeve 10 includes an upper sleeve head 13 and a lower sleeve head 14. The upper sleeve head 13 is rotatably connected to the lower sleeve head 14, and the upper sleeve head 13 is movably connected to the fixing rod 7, and the lower sleeve head 14 is slidably connected to the fixing rod 7. The upper sleeve head 13 can perform lifting actions while rotating, and the lower sleeve head 14 performs lifting actions.

[0025] The end of the spring 11 is fixedly connected to the lower sleeve head 14. A sliding groove 15 is arranged on the outer side of the fixing rod 7, and the lower sleeve head 14 is slidably connected to the sliding groove 15, playing a guiding role for the lower sleeve head 14 and ensuring stable movement.

The water flow swirls down along the inner wall of the tank body 1, which can drive the rotation of the stirring blades 9. At the same time, the eddy current has a vertically downward component force acting on the stirring blades 9, so that the spring 11 is compressed, and the stirring blades 9 move downward while stirring. When the spring 11 is compressed to a certain position, the stirring blades 9 can be lifted, that is, the stirring blades 9 swing up and down while rotating, achieving the purpose of full stirring and further enhancing the reaction effect. Then the sewage is transported to the conveying pipeline 2 through the liquid discharge end 5, which can extend the reaction time and achieve the purpose of full purification, with strong practicability.
