Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3 The figure shows an automatic dosing device for sewage treatment, including a sewage treatment tank 1. An automatic dosing mechanism is provided on the upper side of the sewage treatment tank 1. The automatic dosing mechanism is used to automatically add chemical solution into the sewage treatment tank 1. The automatic dosing mechanism includes a dosing tank 11 provided on the upper end of the sewage treatment tank 1. A guide rod 12 is provided at the bottom of each dosing tank 11. A limiting block 13 is connected to the upper end of the guide rod 12. A spring 14 is sleeved on the outer side of the guide rod 12. A sealing plug 15 is slidably sleeved on the outer side of the guide rod 12. A connecting rod 16 is connected to the lower end of the sealing plug 15. A float ball 17 is connected to the lower end of the connecting rod 16. A chemical inlet 18 is provided at the upper end of the dosing tank 11. The sewage treatment tank 1 is equipped with an internal stirring mechanism to accelerate the mixing of sewage and chemical solution. The stirring mechanism includes a motor 2 installed on the lower end face of the sewage treatment tank 1. The motor 2 converts electrical energy into mechanical energy to drive the structure to rotate. The rotation speed of the motor 2 can be adjusted by a speed controller. The change in the speed controller is transmitted to the current of the motor 2, thereby controlling the speed of the stirrer. The rotating shaft of the motor 2 is connected to the drive pipe 21. A first sealed bearing 22 is installed at the bottom of the sewage treatment tank 1. Drainage holes 23 are provided inside the drive pipe 21. Stirring blades 24 are provided on the outside of the drive pipe 21. The upper end of the drive pipe 21 is connected to a second sealed bearing 25. A flushing mechanism is provided at the upper end of the sewage treatment tank 1. The flushing mechanism is used to flush out impurities inside the sewage treatment tank 1. The flushing mechanism includes a water pipe 26 provided at the upper end of the sewage treatment tank 1. One end of the water pipe 26 is connected to a water pump 27. An inlet pipe 28 is provided at the upper end of the water pump 27.
[0018] The water pump 27 is a machine that transfers the mechanical energy of the prime mover and other external energy to the liquid, thereby increasing the energy of the liquid. Its core purpose is to realize the transportation and pressurization of the liquid.
[0019] Please see Figure 1-3 The bottom of the dosing tank 11 is tightly attached to the sealing plug 15, and the bottom of the dosing tank 11 is fitted with the connecting rod 16; When the sewage inside the sewage treatment tank 1 rises to the position of the float ball 17, the float ball 17 is driven by the buoyancy of the water to move the connecting rod 16 upward, which causes the spring 14 to contract, and the chemical solution inside the dosing tank 11 will automatically flow into the sewage treatment tank 1 for dosing.
[0020] Please see Figure 1-3 The upper end of the spring 14 is connected to the limiting block 13, and the lower end of the spring 14 is connected to the sealing plug 15. The guide rod 12 is designed to guide the longitudinal movement of the spring 14, sealing plug 15, connecting rod 16 and float 17, preventing lateral deviation from affecting normal drug dosing.
[0021] Please see Figure 1 The sewage treatment tank 1 is internally fitted with a stirring blade 24, and the lower end of the drive pipe 21 is connected to a sealed bearing 22. By starting the motor 2, the drive tube 21 and the stirring blade 24 are driven to stir the sewage, thereby accelerating the mixing of sewage and medicine.
[0022] Please see Figure 1 A sewage pipe 29 is installed at the upper end of the sewage treatment tank 1, and a drain pipe 210 is installed at the lower end of one side of the sewage treatment tank 1. The upper end of the outer steel ring of the sealing bearing 25 is connected to the water pipe 26. A water pump 27 is installed at the upper end of the sewage treatment tank 1, and the drive pipe 21 and the water pipe 26 are connected. With this setup, the water pump 27 is started to draw clean water from the water pipe 26 into the drive pipe 21, and the motor 2 is started to drive the drive pipe 21 to rotate. The water is discharged from the drain hole 23 due to centrifugal force, which facilitates cleaning, maintenance and upkeep of the inside of the sewage treatment tank 1.
[0023] The working principle of this embodiment is as follows: When the sewage inside the sewage treatment tank 1 rises to the position of the float ball 17, the float ball 17 is driven by the buoyancy of the water to move the connecting rod 16 upward, which drives the spring 14 to contract, and the chemical solution inside the dosing tank 11 will automatically flow into the sewage treatment tank 1 for dosing. It is worth noting that the design of the guide rod 12 can guide the longitudinal movement of the spring 14, sealing plug 15, connecting rod 16 and float 17 to prevent lateral deviation from affecting normal drug dosing, and the design of the limiting block 13 can limit the range of movement of the sealing plug 15, connecting rod 16 and float 17.
[0024] By starting the motor 2, the drive pipe 21 and the stirring blade 24 are driven to stir the sewage, thereby accelerating the mixing of sewage and medicine. By starting the water pump 27, clean water is drawn from the water pipe 26 into the drive pipe 21. The motor 2 drives the drive pipe 21 to rotate. The water is discharged from the drain hole 23 due to the centrifugal force, which facilitates the cleaning, maintenance and upkeep of the sewage treatment tank 1.
