[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please see Figure 1 - Figure 5This utility model provides an embodiment of a wastewater treatment agent application device, including a fixed base 1, a mixing tank 22, and a spraying assembly. A caster wheel 4 is fixedly connected to the bottom of the fixed base 1, and a push-pull rod 5 is fixedly connected to the right end of the fixed base 1. The spraying assembly is located on the top of the fixed base 1, and the mixing tank 22 is located on the top of the fixed base 1. A motor 26 is fixedly connected to the top of the mixing tank 22, and a first bevel gear 27 is fixedly connected to the output end of the motor 26. A second bevel gear 28 meshes with the external part of the first bevel gear 27. An L-shaped bracket 25 is fixedly connected to the top of the mixing tank 22. A rotating shaft 29 is fixedly connected inside the gear 28. The rotating shaft 29 is rotatably connected inside the L-shaped bracket 25. A stirring plate 210 is fixedly connected outside the rotating shaft 29. A third bevel gear 211 meshes with the first bevel gear 27. A rotating sleeve 212 is fixedly connected inside the third bevel gear 211. The rotating sleeve 212 is rotatably connected inside the mixing tank 22. The rotating shaft 29 is rotatably connected inside the rotating sleeve 212. A scraper 213 is fixedly connected outside the rotating sleeve 212. The stirring plate 210 is fixedly connected to the inner side of the scraper 213. The second bevel gear 28 and the third bevel gear 27 engage with the rotating shaft 27. Gears 211 mesh with the first bevel gear 27, causing the rotating shaft 29 and scraper 213 to rotate synchronously in opposite directions. The rotating shaft 29 drives the stirring plate 210 to perform centrifugal motion, and the scraper 213 also scrapes off the powdery wastewater treatment agent mixture adhering to the inner wall of the mixing tank 22 while the stirring plate 210 is performing centrifugal motion in the opposite direction to the rotation of the rotating shaft 29. This ensures that the wastewater treatment agent in the mixing tank 22 is fully mixed. The spraying assembly sprays the wastewater treatment agent mixture from the liquid pump 31 and moves it up and down via the moving frame 35. The device is movable to meet the user's needs. By removing the rigid tube 313 from the slot of the mounting bracket 312, it is easy to hold the nozzle 314 for spraying, thereby improving the spraying efficiency. Two sets of stirring plates 210 are provided. The two sets of stirring plates 210 are distributed on the outside of the rotating shaft 29 and the inside of the scraper 213, respectively. Both sets of stirring plates 210 are set inside the mixing tank 22. Through the two sets of opposite stirring, the mixing effect of the sewage treatment agent mixture in the mixing tank 22 is improved, and the powdery sewage treatment agent mixture adhering to the inner wall of the mixing tank 22 can be scraped off.
[0026] Please see Figure 1 - Figure 3In this embodiment, an installation frame 21 is fixedly connected to the outside of the mixing tank 22. An internal hexagon bolt 23 is installed inside the installation frame 21 and threadedly connected to the inside of the fixed base 1. A feed valve 24 is fixedly connected to the top of the mixing tank 22, which scrapes off the powdered wastewater treatment agent mixture adhering to the inner wall of the mixing tank 22, reducing waste of the wastewater treatment agent mixture, improving the wastewater treatment effect, and increasing the mixing efficiency of the wastewater treatment agent mixture inside the mixing tank 22, ensuring thorough mixing and improving the practicality of the device. Four sets of internal hexagon bolts 23 are provided, distributed inside the installation frame 21. The installation frame 21 has circular holes at corresponding positions of the four sets of internal hexagon bolts 23, with the internal hexagon bolts 23 positioned within these holes, allowing for easy installation and removal of the mixing tank 22 from the top of the fixed base 1.
[0027] Please see Figure 4 - Figure 5In this embodiment, the spraying assembly includes a liquid pump 31, which is fixedly connected to the top of the fixed base 1. A first connecting hose 32 is fixedly connected between the liquid pump 31 and the mixing tank 22. A fixed plate 33 is fixedly connected to the top of the fixed base 1. A toothed plate 34 is fixedly connected to the front end of the fixed plate 33. A movable frame 35 is slidably connected inside the fixed plate 33. A semi-circular block 36 is fixedly connected inside the movable frame 35. A worm gear 37 is rotatably connected inside the semi-circular block 36. The worm gear 37 is rotatably connected inside the movable frame 35. A rotating disk 38 is fixedly connected to the worm gear 37. A worm wheel 39 meshes with the worm gear 37. An optical shaft 310 is fixedly connected inside the worm wheel 39. The optical shaft 310 is rotatably connected inside the moving frame 35. A circular gear 311 is fixedly connected to the outside of the optical shaft 310. The circular gear 311 meshes with the outside of the toothed plate 34. A placement frame 312 is fixedly connected to the left end of the moving frame 35. A rigid tube 313 is snapped into the inside of the placement frame 312. A nozzle 314 is fixedly connected to the left end of the rigid tube 313. A second connecting flexible tube is fixedly connected between the rigid tube 313 and the liquid pump 31. The rear end of the pipe 315 and the movable frame 35 is fixedly connected to a fixed bracket 316. The second connecting hose 315 is located inside the fixed bracket 316. By spraying the sewage treatment agent mixture from the liquid pump 31, the movable frame 35 can be raised and lowered to meet the user's needs. By removing the rigid pipe 313 from the slot in the placement bracket 312, it is easier to hold the nozzle 314 for spraying, thus improving spraying efficiency. The movable frame 35 has a slot at the corresponding position of the toothed plate 34. The outside of the frame slides so that it is not affected by the toothed plate 34 when the moving frame 35 moves up and down, thus improving its stability. The placement rack 312 has a slot at the corresponding position of the rigid tube 313. The rigid tube 313 is snapped into the slot of the placement rack 312 so that it can be snapped into the slot when it is not needed to be held by hand, thus meeting the user's needs. A limit sleeve is provided on the outside of the rigid tube 313 and the limit sleeve is fixedly connected to the outside of the rigid tube 313, so that it is limited to the inside of the placement rack 312 by the limit sleeve, thus improving its stability.
[0028] During operation, the entire assembly is moved to the desired location via the push-pull rod 5 and toothed plate 34. Then, a wastewater treatment agent mixture is added to the mixing tank 22 through the feed valve 24. At this point, the motor 26 is started, driving the first bevel gear 27 to rotate. The second bevel gear 28 and the third bevel gear 211 mesh with the first bevel gear 27, causing the rotating shaft 29 and scraper 213 to rotate synchronously. The rotating shaft 29 drives the mixing plate 210 in a centrifugal motion. Simultaneously, the scraper 213, driving the mixing plate 210 in a centrifugal motion opposite to the rotation of the rotating shaft 29, also scrapes away the powdery wastewater treatment agent mixture adhering to the inner wall of the mixing tank 22, thus achieving proper treatment of the wastewater treatment agent within the mixing tank 22. After thorough mixing, the liquid pump 31 is started. The liquid pump 31 discharges the wastewater treatment agent from the mixing tank 22 through the first connecting hose 32. The wastewater treatment agent mixture is sprayed from the nozzle 314 through the second connecting hose 315 and the rigid pipe 313. At the same time, the rotating disk 38 is rotated to drive the worm gear 37 to rotate. The worm wheel 39 of the same specification meshes with the worm gear 37, which drives the optical shaft 310 to rotate inside the moving frame 35. This drives the circular gear 311 to mesh with the toothed plate 34, which drives the moving frame 35 to move up and down, thereby meeting the user's needs. By removing the rigid pipe 313 from the slot of the placement rack 312, it is convenient to hold the nozzle 314 for spraying, thereby improving the spraying efficiency.
[0029] Through the above steps, the second bevel gear 28 and the third bevel gear 211 mesh with the first bevel gear 27, causing the rotating shaft 29 and the scraper 213 to rotate synchronously in opposite directions. This scrapes off the powdered wastewater treatment agent mixture adhering to the inner wall of the mixing tank 22, reducing the waste of the wastewater treatment agent mixture. This solves the problem of low mixing efficiency of the treatment agent and the problem of the powdered treatment agent sticking to the inner wall of the equipment because it is quite sticky when it comes into contact with water.
