DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0023] The following describes an embodiment of the utility model based on its overall structure.
[0024] A sewage treatment dosing device, such as Figure 1-7 As shown, the hull 1 includes a rotating motor that can control the rotation of the drum 2. The hull 1 is a hollow structure. The tops of both sides of the inner wall of the hull 1 are installed with dosing devices 7. Each dosing device 7 is connected to a dosing block 11 in an arc-shaped sliding manner. Each dosing block 11 is provided with a dosing groove 12. Each dosing groove 12 penetrates the corresponding dosing block 11 and extends out of one end of the dosing device 7. Each dosing block 11 is located on the top surface of the dosing block 11 that is biased toward the sealed end of the dosing groove 12. Each of the dosing devices 7 is provided with a drug inlet 10, a drug storage tank 8 is provided on the top surface, and a drug adding port 9 is provided on the bottom surface of each drug storage tank 8. The drug inlet 10 cooperates with the drug adding port 9, and the drug is placed in the drug storage tank 8. The drug slides to the sealed end of the drug adding tank 12 through the drug adding port 9 and the drug inlet 10. The drug inlet 10 slides, and the drug inlet 10 is separated from the drug adding port 9. The drug at the sealed end of the drug adding tank 12 slides out from the open end of the drug adding tank 12 due to gravity.
[0025] refer to Figure 6It can be seen that the two dosing devices 7 are located on the side close to each other, where the dosing devices 7 and the medicine box 4 cooperate, and both slide through the limit block 15, and each limit block 15 passes through the outer wall inside the dosing device 7 and is connected to a rack 14. One end of each limit block 15 that passes through the dosing device 7 cooperates with the corresponding medicine box 4. A return spring 16 sleeved on the outer wall of the corresponding limit block 15 is connected between the inner wall of each rack 14 and the inner wall of the corresponding dosing device 7. A transmission shaft 13 is rotatably connected between the upper and lower ends of the inner wall of each dosing device 7. A thread is provided on the upper end of each transmission shaft 13, and a tooth pattern is provided on the lower end of each transmission shaft 13. The lower end of each transmission shaft 13 is meshed with the corresponding rack 14, and each dosing device 7 is connected to the inner wall of each rack 14. The inner wall of the medicine device 7 is located above the corresponding limit block 15 and is rotatably connected with a gear 17, and the upper end of each gear 17 is meshed with the corresponding transmission shaft 13, and the ends of the two gears 17 that are close to each other are meshed with the inner part of the outer wall of the corresponding dosing block 11. When the medicine box 4 touches the corresponding dosing device 7, the limit block 15 is pushed back by the medicine box 4. At this time, the rack 14 arranged on the outer surface of the limit block 15 is meshed with the transmission shaft 13, so that the transmission shaft 13 rotates, and the transmission shaft 13 drives the dosing block 11 to slide out of the dosing device 7 through the gear 17. When the medicine box 4 is separated from the corresponding dosing device 7, the reset spring 16 pushes the limit block 15 to reset, and the rack 14 moves in the opposite direction. Repeat the above operation, and the dosing block 11 retreats to the inside of the dosing device 7.
[0026] refer to Figure 2 It can be seen that a rotating drum 2 is rotatably connected between the two sides of the inner wall of the hull 1 and below the dosing device 7. Both sides of the outer wall of the rotating drum 2 are wound with connecting wires 3, and the winding directions of the two connecting wires 3 are opposite. The movable ends of the two connecting wires 3 are connected to medicine boxes 4. The medicine boxes 4 are hollow structures. The bottom surfaces of the inner sides of the two dosing devices 7 are matched with the corresponding medicine boxes 4, and the two medicine boxes 4 do not contact the corresponding dosing devices 7 at the same time. The upper sides of the two medicine boxes 4 that are close to each other are connected with torsion springs 5, and each torsion spring 5 is connected to the upper side of the two medicine boxes 4. The bottom end of the spring 5 is connected to a limit plate 6 that cooperates with the opening of the corresponding medicine box 4. One end of the opening of the dosing block 11 cooperates with the corresponding limit plate 6. The sliding dosing block 11 pushes the limit plate 6 in the corresponding medicine box 4 to rotate along the torsion spring 5. The slipped medicine falls into the interior of the medicine box 4, the rotating drum 2 rotates, the medicine box 4 is separated from the dosing block 11, and the torsion spring 5 controls the limit plate 6 to reset. At this time, the medicine box 4 is closed and sinks into the water along the connecting line 3, and the other medicine box 4 rises synchronously until the other medicine box 4 contacts the dosing device 7.
[0027] Working principle: the hull 1 controls the equipment to move freely on the water surface, and the medicine storage tank 8 contains medicine. In the initial state, the medicine inlet 10 is located at the sealed end of the medicine dosing tank 12, which is biased toward the vertical plane of the axis of the medicine dosing block 11. Therefore, under the influence of gravity, the medicine slides to the sealed end of the medicine dosing tank 12 through the medicine dosing port 9 and the medicine inlet 10. When the drum 2 rotates, so that the medicine box 4 touches the corresponding dosing device 7, the limit block 15 is pushed back by the medicine box 4. At this time, the rack 14 arranged on the outer surface of the limit block 15 engages with the transmission shaft 13, so that the transmission shaft 13 rotates, and the transmission shaft 13 drives the dosing block 11 to slide out of the dosing device 7 through the gear 17, and the medicine inlet 10 is disengaged from the medicine dosing port 9. At this time, the sealed end and the open end of the dosing tank 12 are both on the same side of the vertical plane of the axis of the medicine dosing block 11, so the medicine at the sealed end of the dosing tank 12 is affected by gravity. It slides out from the open end of the dosing groove 12, and the dosing block 11 that slides out pushes the limit plate 6 in the corresponding medicine box 4 to rotate along the torsion spring 5, and the medicine that slides out falls into the inside of the medicine box 4, and the drum 2 rotates forward. When the medicine box 4 is separated from the corresponding dosing device 7, the reset spring 16 pushes the limit block 15 to reset, and the rack 14 moves in the opposite direction, and the above operation is repeated. The dosing block 11 retreats to the inside of the dosing device 7, and the medicine box 4 is separated from the dosing block 11. The torsion spring 5 controls the limit plate 6 to reset. At this time, the medicine box 4 is closed and sinks into the water along with the connecting line 3, and the medicine dissolves in the water. The other medicine box 4 rises synchronously until the other medicine box 4 contacts the dosing device 7. After a period of time, the above operation is repeated, the drum 2 reverses, and the medicine box 4 located above sinks into the water again, and the original medicine box 4 rises, and finally the automatic dosing of the equipment in deep water is completed.
