[0002] The development of industry has driven the rapid development of related industries and has become one of the important pillars of the national economy. However, countries that have experienced rapid industrial development understand that the development of industry also means the destruction of the natural environment, especially the serious pollution of water sources. Therefore, the protection of water sources, the treatment of sewage, and the purification of water are very important. When treating industrial sewage, it is necessary to mix the medicine with the aqueous solution to make a liquid medicine before adding it into the sewage treatment cylinder. These medicines have solid particles and liquids. They must be dissolved, diluted, and quantitatively added according to the ratio during the addition process to achieve the best effect. In the publication number CN216303312U, a water treatment equipment water inlet dosing device is disclosed, which can quantitatively add medicine according to the water flow entering the water treatment equipment. It has a simple structure and does not require too much external power equipment. It relies on the water flow drive device to quantitatively add medicine. However, when the water flow is low or there is no water, the cam is prone to fail to lift the clamping wheel, so the internal medicine continues to enter the water inlet pipe, resulting in a waste of medicine.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a dosing device for a water inlet of a water treatment equipment, comprising a fixed pipe 1, wherein both ends of the fixed pipe 1 are connected to a water inlet pipe 2, the fixed pipe 1 and the water inlet pipe 2 are fixedly connected by bolts and are provided with a sealing ring, a dosing pipe 3 is fixedly connected to the top of the fixed pipe 1, a medicine storage box 4 is fixedly connected to the top of the dosing pipe 3, the dosing pipe 3 is communicated with the fixed pipe 1 and the medicine storage box 4, a first bracket 5 and a second bracket 6 are fixedly connected in sequence from top to bottom in the dosing pipe 3, a sliding rod 7 is vertically slidably connected to the center of the first bracket 5 and the second bracket 6, the top of the sliding rod 7 extends to the top of the first bracket 5 and is fixedly connected with a sealing plug 11, the inner wall of the dosing pipe 3 is provided with a sealing seat 12 adapted to the sealing plug 11, when the sealing plug 11 contacts the sealing seat 12, the medicine in the medicine storage box 4 cannot enter the fixed pipe 1, the surface of the sliding rod 7 and located above the second bracket 6 are threadedly connected with a fixing ring 8 and a locking nut 9, the top of the fixing ring 8 is connected to the bottom of the first bracket 5 A spring 10 is arranged between the parts, which is threadedly connected with the sliding rod 7 through the fixing ring 8, so that the position of the fixing ring 8 can be adjusted, thereby the length of the spring 10 can be adjusted, and the upward thrust required for adjusting the sliding rod 7 when sliding is realized, and the fixing of the fixing ring 8 is realized by the locking nut 9 to prevent the fixing ring 8 from loosening. A baffle 13 is arranged in the fixed tube 1, and a fixing shaft 14 is arranged on both sides of the baffle 13. The fixing shaft 14 is rotatably connected to the fixed tube 1, and a connecting rod 15 is rotatably connected between the top of the baffle 13 and the sliding rod 7. The baffle 13 includes a frame 131, and a panel 132 is fixedly connected in the frame 131. The surface of the panel 132 is provided with a water-permeable hole, and a connecting seat 133 is arranged on the top of the frame 131. When the surface of the baffle 13 is subjected to water flow resistance, the baffle 13 rotates around the fixing shaft 14, thereby driving the sliding rod 7 to move upward through the connecting rod 15, and the sealing plug 11 is separated from the sealing seat 12, and the medicine liquid in the medicine storage box 4 enters the fixed tube 1 and mixes with water to realize dosing.

[0018] Both ends of the fixed shaft 14 extend to the outside of the fixed tube 1 and are fixedly connected to a mounting block 22. A fixed frame 23 is fixedly connected to the surface of the fixed tube 1. A torsion spring 24 is arranged between the fixed frame 23 and the mounting block 22. The torsion spring 24 ensures that the baffle 13 can rotate in the absence of water flow, so that the slide rod 7 is in the lowest position. At this time, the sealing plug 11 is in contact with the sealing seat 12, and no liquid medicine flows out.

[0019] A limit block adapted to the baffle 13 is provided in the fixed tube 1. When one side of the baffle 13 contacts the limit block, the baffle 13 is in a vertical state, corresponding to the state of maximum water flow. At this time, the slide bar 7 is in the highest position. The limit block prevents the baffle 13 from rotating too much when the water flow is large, resulting in a reduction in the dosage.

[0020] A motor fixing frame 16 is arranged between the top sides of the fixed tube 1 and the bottom of the medicine storage box 4, and a motor 17 is arranged in the motor fixing frame 16. The two sides inside the medicine storage box 4 are vertically rotatably connected with stirring rods 18, and one end of the stirring rod 18 is transmission-connected to the output shaft end of the motor 17. A stirring blade 19 is arranged on the surface of the stirring rod 18. The motor 17 drives the stirring blade 19 to rotate around the stirring rod 18 through the stirring rod 18, so as to stir the medicine liquid and make the medicine liquid mixed evenly.

[0021] A dosing cover 20 is provided on the top of the medicine storage box 4 to facilitate dosing of medicine, and an observation window is provided on the surface of the medicine storage box 4 to facilitate observation of the remaining medicine liquid.

[0022] An adjustment hole cover 21 is provided on the surface of the dosing tube 3 at a position corresponding to the fixing ring 8. The adjustment hole cover 21 is fixed to the dosing tube 3 by screws and is provided with a sealing ring. By opening the adjustment hole cover 21, the position of the fixing ring 8 and the locking nut 9 can be adjusted conveniently, thereby adjusting the dosage.

[0023] When in use, water and liquid medicine are added through the dosing cover 20, and the liquid medicine is stirred by starting the motor 17. When water flows through the water inlet pipe 2, the water flow pushes one side of the baffle 13, causing the baffle 13 to rotate around the fixed axis 14, thereby driving the slide bar 7 to move upward through the connecting rod 15, and the sealing plug 11 is separated from the sealing seat 12, and the liquid medicine in the medicine storage box 4 enters the fixed pipe 1 and mixes with the water to achieve dosing; when there is no water in the water inlet pipe 2, the baffle 13 is reset under the action of the torsion spring 24, and the slide bar 7 is also reset under the action of the spring 10, and the sealing plug 11 contacts the sealing seat 12 to achieve sealing.
