[0002] Reaction liquid dosing device for wastewater treatment: It is a dosing device for processing wastewater. It has a simple structure and is easy to operate. However, with the advancement of science and technology, people have higher and higher functional requirements for reaction liquid dosing devices for wastewater treatment. The existing reaction liquid dosing device has certain disadvantages when used. First of all, the existing reaction liquid dosing device cannot handle the odor produced after the wastewater is dosed, which is easy to endanger the health of others and has certain inconveniences, which has brought certain impacts to people's use process. For this reason, we propose a reaction liquid dosing device for wastewater treatment.

[0003] In order to solve the above technical problems, a Chinese patent with authorization announcement number CN110337255A discloses a reaction liquid dosing device for wastewater treatment; the article proposes: first connect the guide pipe with the upper cover of the dosing device, and then fix the rubber sealing port with the upper cover of the dosing device. After that, fix the upper cover of the dosing device with the shell of the dosing device through a slot, and then add medicine to the inside of the rubber sealing port. Because the inner wall of the guide pipe is long, it causes the flow time to the bottom to be slow, which can play a buffering role. At this time, people fix the sliding cover with the upper cover of the dosing device through the sliding groove to prevent the gas generated by the excessive reaction from endangering the health of others. The whole reaction liquid dosing device for wastewater treatment has a simple structure, is easy to operate, and has a better effect than the traditional method.

[0004] Although the above device can add medicine to the reaction liquid, when liquid medicine needs to be added, intermittent addition cannot be performed, which can easily lead to excessive addition of medicine, resulting in waste of medicine. Utility Model Content

[0023] Working principle: When in use, the medicine in the medicine tank 1 enters the interior of the containing box 32 from the drainage pipe 2, and the medicine enters the interior of the containing frame 39 through the docking hole 42 and the medicine discharge port 41, and is finally discharged through the liquid outlet pipe 40 and added to the sewage tank. The containing box 32 rotates slowly under the drive of the servo motor 43, the driving gear 45, and the driven gear 46. When the medicine discharge port 41 and the docking hole 42 are disengaged, the liquid outlet pipe 40 stops discharging medicine, thereby realizing intermittent medicine addition to the sewage tank. When the medicine addition is completed, the valve on the drainage pipe 2 is closed to stop the medicine addition, so that the amount of medicine added can be controlled to avoid waste caused by excessive medicine addition.

[0024] As a preferred embodiment, a fixing plate 31 is fixedly installed on the outer side of the blocking cover 30, and the bottom of the fixing plate 31 is movably connected to the containing box 32 via a sealed bearing, and both the blocking cover 30 and the containing box 32 are circular structures.

[0025] like Figure 2 As shown: when the lower medicine port 41 and the docking hole 42 are offset, the internal liquid of the receiving box 32 will gather. At this time, the blocking cover 30 and the receiving box 32 are movably connected through a sealing bearing to avoid leakage between the blocking cover 30 and the receiving box 32.

[0026] As a preferred embodiment, a side sealing gasket 33 is fixedly provided on the outer side of the switching seat 34 , and the bottom of the switching seat 34 is fixedly connected to the bottom sealing gasket 35 , and the accommodating box 32 and the switching seat 34 are sealed by the side sealing gasket 33 and the bottom sealing gasket 35 .

[0027] like Figure 2 As shown: the containing box 32 and the switching seat 34 are sealed by the side sealing gasket 33 and the bottom sealing gasket 35; the setting of the sealing gasket 33 and the bottom sealing gasket 35 ensures that when the lower medicine port 41 and the docking hole 42 are staggered, the liquid inside the containing box 32 will not enter the gap between the containing box 32 and the switching seat 34.

[0028] As a preferred embodiment, the medicine discharge port 41 and the docking hole 42 are in relative positions, and the medicine inside the medicine tank 1 enters the interior of the containing frame 39 from the drainage pipe 2, the docking hole 42, and the medicine discharge port 41, and is finally discharged through the liquid outlet pipe 40 and added to the sewage tank.

[0031] The output shaft of the servo motor 43 drives the driving gear 45 to rotate slowly, and the driving gear 45 drives the docking hole 42 to rotate slowly through the driven gear 46. By changing the docking time between the drug dispensing port 41 and the docking hole 42, slow intermittent drug addition to the sewage tank is achieved.

[0032] As a preferred embodiment, the rotating shaft of the driving gear 45 is fixed to the output shaft of the servo motor 43, and the servo motor 43 is screwed on the "U"-shaped limit seat 44. At the same time, the bottom of the limit seat 44 is screwed and fixed to the base 38, and a slide groove 381 is opened on the surface of the base 38. Four groups of sliders 37 are slidingly arranged inside the slide groove 381, and the four groups of sliders 37 are evenly screwed to the circumferential position of the bottom of the receiving box 32 through the bottom plate 36.

[0033] When the receiving box 32 rotates, the four groups of sliders 37 at the bottom thereof are slidably arranged inside the slide groove 381, which can limit and guide the receiving box 32 during movement, thereby ensuring the stability of the receiving box 32 during movement and preventing the driving gear 45 and the driven gear 46 from disengaging.
