DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] Please refer to Figures 1-6 As shown in the figure, a dosing device for water pollution prevention and control includes a dosing mechanism 100, which includes a sewage pool 110 and the following parts: the dosage adjusting mechanism 300 is fixed to one end of the top wall of the sewage pool 110, and the pipe pressing mechanism 200 is fixed to the top wall of the pool opening of the sewage pool 110, and the filter replacement mechanism 400 is fixed to the dosage adjusting mechanism 300. The pipe pressing mechanism 200 includes the following parts: the support frame 210 is fixedly connected with the pool opening of the sewage pool 110, and the water pipe 211 is inserted into the inside of the support frame 210, the spray head 220 is provided with a plurality of equidistantly fixed outer walls on the water pipe 211, and is slidably inserted with the outer wall of the support frame 210, the arc-shaped frame 231 is provided with a plurality of equidistantly slidably inserted inside the support frame 210, and the partition 230 is fixed to the top wall of the arc-shaped frame 231, and the spring telescopic rod 242 is provided with a plurality of equidistantly fixed between the partition 230 and the outer wall of the support frame 210. The filter replacement mechanism 400 includes the following parts: the slide rail one 410 is fixed with the outer wall of the dosage adjusting mechanism 300, and the rack 411 is slidably inserted into the slide rail one 410, the round rod 420 is fixed to one end of the outer wall of the slide rail one 410, the spur gear 421 is fixed to the shaft of the round rod 420, and is engaged with the rack 411.

[0050] The round rod 420 is provided with several equally spaced rotational points on the outer wall of the dosage adjustment mechanism 300. The spur gear 421 is fixed on the outer wall of the round rod 420 and meshes with the outer wall of the rack 411 for transmission. The ring frame 426 is provided with several fixed points on the outer wall of the dosage adjustment mechanism 300 near the round rod 420. The inclined block 427 is provided with several fixed points at equal angles on the outer wall of the ring frame 426. The slide rail 422 is provided with two fixed points at equal angles on the outer wall of the round rod 420. The square rod 423 slides inside the slide rail 422. The round tube 425 is fixed to the outer wall of one end of the square rod 423. The filter screen 428 is fixed to one end inside the round tube 425. The spring 424 is fixed between the outer wall of the square rod 423 and the inner wall of the slide rail 422.

[0051] Specifically, during operation, the reagent flows through the filter screen 428 for filtration. When the round tube 425 becomes clogged due to excessive impurities, the round rod 420 drives the spur gear 421 to rotate and mesh with the rack 411. This causes the rack 411 to move and mesh with the spur gear 421, resulting in the used round tube 425 and the unused round tube 425 exchanging positions. During this process, the outer wall of the square rod 423 contacts the outer wall of the inclined block 427, causing the square rod 423 to be squeezed and slide inward toward the slide rail 422. Through rapid movement, coupled with the rebound of the spring 424, the movement... The process causes the circular tube 425 to vibrate, shaking out impurities from one end. The impurities and residual chemicals fall into the filter tank. After filtration, the residual chemicals are discharged through the pipe. When the chemicals flow into the water pipe 211 through the dosage adjustment mechanism 300, the arc frame 231 slides upward under the pressure of the chemicals. When the chemicals are discharged from the nozzle 220, the residual chemicals will be pushed downward by the spring extension rod 242, squeezing the water pipe 211 and discharging the residual chemicals from the nozzle 220.

[0052] Example 1

[0053] like Figures 4-5 As shown, in this embodiment, the filter replacement mechanism 400 includes: a slide rail 410 fixed to the outer wall of the dosage adjustment mechanism 300, a rack 411 sliding inside the slide rail 410, a round rod 420 fixed to the outer wall of one end of the slide rail 410, a spur gear 421 fixed to the rotating shaft of the round rod 420 and meshing with the rack 411 for transmission, and the round rod 420 having several equally spaced spurs that rotate with the outer wall of the dosage adjustment mechanism 300, while the spur gear 421 is fixed to the outer wall of the round rod 420 and meshing with the outer wall of the rack 411 for transmission.

[0054] In this embodiment, the round rod 420 drives the spur gear 421 to rotate and mesh with the rack 411, which in turn drives the rack 411 to move and mesh with the spur gear 421. This causes the used round tube 425 to exchange positions with the unused round tube 425. The movement of the rack 411 can simultaneously drive multiple round tubes 425 to be replaced, effectively improving mechanical linkage. Quick replacement can be performed without human intervention, effectively improving operational convenience. Sealing elements are provided on the outer walls of both ends of the round tube 425 to effectively improve sealing performance.

[0055] like Figures 4-6 As shown, in this embodiment, the filter replacement mechanism 400 includes the following parts: its ring frame 426 is provided with several fixed to the outer wall of the drug dosage adjustment mechanism 300 near the round rod 420, and the inclined block 427 is provided with several fixed at equal angles to the outer wall of the ring frame 426; the slide rail 422 is provided with two fixed at equal angles to the outer wall of the round rod 420; its square rod 423 slides inside the slide rail 422; and the round tube 425 is fixed to the outer wall of one end of the square rod 423; the filter screen 428 is fixed to one end inside the round tube 425; and its spring 424 is fixed between the outer wall of the square rod 423 and the inner wall of the slide rail 422.

[0056] In practice, during the movement of the circular tube 425, the outer wall of the square rod 423 contacts the outer wall of the inclined block 427, causing the square rod 423 to be squeezed and slide inward toward the slide rail 422. Through rapid movement, coupled with the rebound of the spring 424, the circular tube 425 vibrates during the movement, shaking out impurities from one end. The impurities and residual chemicals fall into the filter tank. After filtration in the filter tank, the residual chemicals are discharged along the pipe. By vibrating during the movement of the circular tube 425, impurities can be shaken out. Combined with water flushing by personnel, the circular tube 425 can be quickly cleaned, making it convenient for the next use. At the same time, it simplifies the cleaning operation for personnel, effectively improving convenience and cleaning efficiency.
