[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic dosing system for wastewater treatment equipment, comprising a tank 1. A liquid level detection mechanism 2 is installed on the front side of the outer wall of the tank 1. The liquid level detection mechanism 2 is used to detect the remaining liquid level inside the equipment and prevent overflow during dosing. A flow limiting mechanism 3 is provided on the right side of the outer wall of the tank 1. The flow limiting mechanism 3 is used to regulate the liquid flow rate inside the equipment. The liquid level detection mechanism 2 includes a motor 201. The motor 201 is a micro motor. The micro motor 201 converts electrical energy into mechanical energy and uses the principle of electromagnetic induction to make the internal rotor rotate under the force of a magnetic field, thereby outputting power to drive the associated equipment. The components are in operation. The motor 201 is installed on the lower middle part of the front side of the inner wall of the barrel 1. The output end of the motor 201 is fixedly connected to the front side of the outer wall of the gear 202. The bottom of the outer wall of the gear 202 is meshed with the rack 203. The bottom of the outer wall of the rack 203 is fixedly connected to the movable door 204. The bottom of the front side of the inner wall of the barrel 1 is provided with a feeding hole 205. The right side of the feeding hole 205 is provided with a sliding groove 206. The left end of the front side of the outer wall of the barrel 1 is connected to a liquid level sensor 207. The liquid level sensor 207 is a float-type liquid level sensor 207. The top front side of the outer wall of the barrel 1 is fixedly connected to a three-color alarm light 208. The bottom of the outer wall of the multi-head pipe 13 is connected to a branch pipe 16. The bottom of the outer wall of the branch pipe 16 is connected to a three-way pipe 17. The top of the outer wall of the three-way pipe 17 is provided with a valve 18. The top of the valve 18 is connected to a nozzle 19, which sprays water. Specifically, when the equipment is storing materials, the motor 201 is first started, and the output end of the motor 201 rotates, driving the gear 202 to rotate synchronously. Since the gear 202 and the rack 203 are in a meshing state, the rotational motion of the gear 202 is converted into the movement of the rack 203 through meshing transmission, which synchronously drives the movable door 204 fixedly connected to it to move. The movable door 204 is retracted into the inner wall of the preset sliding groove 206. At this time, the movable door 204 is in the open state, and the equipment enters the material storage operation stage. The liquid level sensor 207 installed at a designated position in the barrel 1 monitors and marks the liquid level of the material inside the barrel 1. When the liquid level of the material inside the barrel 1 reaches the preset storage threshold, the liquid level sensor 207 immediately triggers a signal output. This signal is synchronously transmitted to the control system and the motor 201. The motor 201 starts the reverse operation program, driving the gear 202 to rotate in the reverse direction. Through the meshing transmission of the gear 202 and the rack 203, the rack 203 and the movable door 204 move in the reverse direction until the movable door 204 resets, thus sealing the barrel 1. At this time, the tri-color alarm light 208 receives the liquid level reaching the target signal and activates an early warning to indicate that the material storage operation has been completed. When the material level in the tank 1 drops to the preset low liquid level threshold, the liquid level sensor 207 triggers a signal output. This low liquid level signal is transmitted to the tri-color alarm light 208, which then provides a warning, indicating that the material level in the tank 1 is low and reminding the user to replenish the material in a timely manner.

[0021] Reference Figure 2 , Figure 5 and Figure 6 The flow limiting mechanism 3 includes a connecting pipe 303. An adjusting groove 301 is provided on the top of the outer wall of the connecting pipe 303. Outer rings 309 are installed on both the left and right sides of the inner wall of the connecting pipe 303. A movable groove 311 is provided on the top of the outer wall of the outer ring 309. A lever 302 is provided on the inner wall of the movable groove 311. A second rotating groove 310 is equidistantly provided on the middle of the left side of the inner wall of the outer ring 309. A second fixing bolt 308 is rotatably connected to the inner wall of the second rotating groove 310. A hinge 306 is rotatably connected to the left side of the outer wall of the second fixing bolt 308. A first fixing bolt 307 is fixedly connected to the left side of the outer wall of the hinge 306. A limit switch is installed on the left side of the inner wall of the outer ring 309. Ring 304, the outer wall of the limiting ring 304 is provided with rotating grooves 305 at equal intervals, the top of the outer wall of the fixing bolt 307 is fixedly connected to the lever 302, the lever 302 is installed on the inner wall of the movable groove 311, the bottom of the operating cabinet 7 is fixedly connected to the four corners of the bottom, the bottom of the outer wall of the base 8 is fixedly connected to the rubber pad 11, the bottom left side of the frame 6 is fixedly connected to multiple water pumps 12, the water pumps 12 are centrifugal water pumps 12 (IH), the right side of the outer wall of the water pump 12 is connected to the multi-head pipe 13, the top of the outer wall of the multi-head pipe 13 is connected to the branch pipe 14, the top of the outer wall of the branch pipe 14 is connected to the pressure valve 15. Specifically, align the discharge pipe 5 with the interface end of the connecting pipe 303, insert the discharge pipe 5 into the connecting pipe 303 to ensure they fit together and form a fluid channel, thus connecting the equipment pipeline. When it is necessary to adjust the discharge flow rate of the equipment, press the lever 302. The lever 302 slides along the inner wall of the preset movable groove 311. Since the lever 302 is connected to the limiting ring 304, the sliding of the lever 302 will synchronously drive the limiting ring 304 to rotate. As the limiting ring 304 rotates, the preset rotating groove 305 on its inner wall will rotate with the limiting ring 304. Through the groove wall of the rotating groove 305, the fixing bolt 307 is transmitted, pushing the fixing bolt 307 to move in a direction along the trajectory of the rotating groove 305. The movement of the fixing bolt 307 drives the hinge 306, causing the hinge 306 to retract around the hinge point, changing the opening and closing angle of the hinge 306. During the retraction of hinge 306, the other end fixing bolt 308 will rotate within the preset rotating groove 310 as the angle of hinge 306 changes. Fixing bolt 308 is always engaged inside the rotating groove 310. Through the limiting effect of rotating groove 310, one end of hinge 306 is kept in a stable position, preventing hinge 306 from shifting as a whole during adjustment, and ultimately achieving the adjustment of the equipment's output flow rate.

[0022] Reference Figure 1 , Figure 2 and Figure 3A discharge pipe 5 is connected to the bottom right side of the outer wall of the barrel 1. A sign 4 is fixedly connected to the middle front side of the outer wall of the barrel 1. A frame 6 is set on the right side of the barrel 1. An operating cabinet 7 is fixedly connected to the bottom front side of the outer wall of the frame 6. Multiple buttons 10 are installed on the lower middle front side of the outer wall of the operating cabinet 7. A display screen 9 is fixedly connected to the middle front side of the outer wall of the operating cabinet 7. Specifically, the discharge pipe 5 connects the entire equipment, the sign 4 marks the inside of the barrel 1 for easy use, the frame 6 connects the equipment, the control cabinet 7 controls the equipment, and the buttons 10 and the display screen 9 operate the equipment.

[0023] Working principle: When the equipment is storing materials, the motor 201 is started, and the output end of the motor 201 rotates, driving the gear 202 to rotate. Since the gear 202 meshes with the rack 203, the rack 203 moves, and the rack 203 drives the movable door 204 to move, retracting the movable door 204 into the inner wall of the sliding groove 206. At this time, the material is stored. The liquid level sensor 207 marks the liquid level in the tank 1. When the liquid level reaches the storage capacity, the liquid level sensor 207 sends a signal, and at the same time, the motor 201 starts to reset the movable door 204, and the three-color alarm light 208 provides a warning. When the liquid level in the tank 1 is low, the liquid level sensor 207 sends a signal and the three-color alarm light 208 provides a warning. Insert the discharge pipe 5 into the connecting pipe 303 to connect the equipment. When it is necessary to adjust the equipment flow rate, pull the lever 302 so that the lever 302 slides inside the movable groove 311. The lever 302 drives the limiting ring 304 to rotate. The rotation of the limiting ring 304 causes the first rotating groove 305 to shift, thereby pushing the first fixing bolt 307 to move. The first fixing bolt 307 then pushes the hinge 306 to retract. The hinge 306 causes the second fixing bolt 308 to rotate. The second fixing bolt 308 rotates on the inner wall of the second rotating groove 310, so that one end of the hinge 306 can be fixed to prevent positional displacement, thereby realizing the adjustment of the equipment flow rate.
