In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.
[0027] like Figures 1-6As shown, a chemical dosing device includes a water conveying channel 1, a self-adjusting dosing mechanism 2 installed on the water conveying channel 1, and a chemical storage mechanism 3 installed on the front of the water conveying channel 1. The self-adjusting dosing mechanism 2 includes a support 21 and a buoyancy switch device 27. The support 21 is fixedly installed on the top of the water conveying channel 1. A diversion pipe 22 is fixedly installed at the end of the support 21 away from the water conveying channel 1. A diversion solenoid valve 23 is fixedly connected to the bottom of the diversion solenoid valve 23. An extension pipe 24 is fixedly connected to the bottom of the extension pipe 24. A square pipe 25 is fixedly connected to the bottom of the extension pipe 24. A perforated pipe 26 is fixedly connected to both the front and back of the square pipe 25. The chemical is conveyed into the inner cavity of the diversion pipe 22. Controlling the opening of the corresponding diversion solenoid valve 23 can cause the chemical to be conveyed through the extension pipe 24 and the square pipe 25, and then output from the perforated pipe 26 at the corresponding height, so as to control the output amount of the chemical according to the fluctuation of the water flow.
[0028] In this embodiment, the buoyancy switch device 27 includes a fixed housing 271, which is fixedly installed on the back side of the inner wall of the water conveying channel 1. A connecting arm 272 is fixedly installed on the outer wall of the fixed housing 271. A collar 273 is fixedly installed at the end of the connecting arm 272 away from the fixed housing 271. A sliding shaft 274 is slidably connected to the inner wall of the collar 273. A buoyancy block 275 is fixedly installed at the bottom of the sliding shaft 274. A push switch 276 is fixedly installed at the top of the inner wall of the fixed housing 271. A rubber pad 277 is fixedly connected to the bottom of the fixed housing 271. The push switch 276 is used to control a porous pipe at a similar height. The diversion solenoid valve 23 corresponding to 26 is opened and closed. The push switch 276 is an existing push button switch, that is, it is energized when pressed and de-energized when released. When the water flow inside the water conveyance channel 1 increases, the water level will rise. Through the buoyancy of the buoyant block 275 inside the water body, the buoyant block 275 can be driven to slide upward inside the collar 273 via the sliding shaft 274. Subsequently, it squeezes the rubber pad 277 to press the push switch 276, that is, to realize the function of controlling the opening of the corresponding diversion solenoid valve 23. After the water level drops, the buoyant block 275 then slides downward, releasing the pressing state of the push switch 276, and the corresponding diversion solenoid valve 23 will close.
[0029] In this embodiment, the drug storage mechanism 3 includes a drug storage tank 31, which is fixedly installed on the front of the water conveyance channel 1. A pump 32 is fixedly installed at the bottom of the drug storage tank 31, and the input pipe of the pump 32 is fixedly connected to the center of the bottom of the drug storage tank 31. A three-way pipe 33 is fixedly installed at the top of the drug storage tank 31, and the output pipe of the pump 32 is fixedly connected to the right side of the three-way pipe 33. An output solenoid valve 34 is fixedly connected to the top of the three-way pipe 33, and an output pipe 35 is fixedly connected to the top of the output solenoid valve 34. The end of the output pipe 35 away from the output solenoid valve 34 is fixedly connected to the top of the diversion pipe 22. A circulation solenoid valve 36 is fixedly connected to the left side of the three-way pipe 33, and a diversion block 37 is fixedly connected to the left side of the circulation solenoid valve 36. A return pipe 38 is fixedly connected to the outer wall of the diversion block 37, and the end of the return pipe 38 away from the diversion block 37 extends into the inner cavity of the drug storage tank 31 and is fixedly connected to a strip pipe 39. A nozzle 391 is fixedly connected to the outer wall of the strip tube 39. The medicine is pre-added into the inner cavity of the medicine storage chamber 31 for storage. The output solenoid valve 34 is opened and the circulation solenoid valve 36 is closed. The pump 32 is then controlled to work, which can draw the medicine inside the medicine storage chamber 31 and then transport it to the inside of the diversion pipe 22 through the three-way pipe 33, the output solenoid valve 34, and the output pipe 35 to facilitate the output of the medicine. If the medicine inside the medicine storage chamber 31 has been idle for too long, before adding medicine, the output solenoid valve 34 is closed and the circulation solenoid valve 36 is opened. The pump 32 is then controlled to work, draw the medicine inside the medicine storage chamber 31, and then transport it to the inside of the strip tube 39 through the circulation solenoid valve 36, the diversion block 37, and the return pipe 38. The medicine will be divided into two streams and output from two sets of nozzles 391. They will be impacted and mixed and then flow back into the inner cavity of the medicine storage chamber 31, thus realizing the function of internal circulation mixing of the medicine to ensure the effect of the medicine.
[0030] The working principle of this chemical dosing device is as follows: During use, water flows through the inner cavity of the water conveying channel 1 to the interior of the regulating tank. Chemicals are pre-added to the inner cavity of the chemical storage tank 31 for storage. Then, the output solenoid valve 34 is opened and the circulation solenoid valve 36 is closed. The pump 32 is then controlled to operate, drawing chemicals from the chemical storage tank 31 and transporting them through the three-way pipe 33, output solenoid valve 34, and output pipe 35 to the interior of the diversion pipe 22. The chemicals are then transported through the extension pipe 24 and square pipe 25, and finally output from the porous pipe 26 to the interior of the water body, thus achieving the dosing function. The buoyancy switch device 27 controls the corresponding diversion solenoid valve 23 to open when the water level in the water conveying channel 1 reaches a specified height, outputting chemicals from the outer surface of the porous pipe 26 at the corresponding height. When the water level drops, the corresponding diversion solenoid valve 23 is closed, achieving the function of automatically adjusting the amount of chemicals added according to the fluctuations in water flow.
