[0038] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1-Figure 4 As shown, the utility model proposes a dosing chain device for wastewater treatment, which mainly includes a dosing tank 1, a dosing pipe 2, a reflux pipe 5, a dosing tank 7, a first stirring member 8 and a second stirring member 9.

[0040] A liquid level gauge (not shown in the figure) is provided in the medicine tank 1, and the liquid level in the medicine tank 1 can be judged according to the liquid level gauge. One end of the dosing pipe 2 is connected to the bottom of the medicine tank 1, and a dosing pump 3 and a first solenoid valve 4 are provided on the dosing pipe 2. One end of the return pipe 5 is connected to the dosing pipe 2, and the connection between the return pipe 5 and the dosing pipe 2 is located between the dosing pump 3 and the first solenoid valve 4. A flow meter 10 is provided on the dosing pipe 2, and the flow meter 10 is located on the side of the first solenoid valve 4 away from the connection between the return pipe 5 and the dosing pipe 2. The other end of the return pipe 5 is connected to the top of the medicine tank 1, and a second solenoid valve 6 is provided on the return pipe 5. The top of the dosing tank 7 is connected to the other end of the dosing pipe 2, and an outlet is provided at the bottom of the dosing tank 7.

[0041] The first stirring member 8 is located in the dosing tank 7 and is rotatably arranged on the central axis of the dosing tank 7. The first stirring member 8 includes a first main rod 81, a first stirring blade 82 and a second stirring blade 83. The lower end of the first main rod 81 extends into the dosing tank 7. The first stirring blade 82 is arranged in a plurality of axially arranged along the first main rod 81. Each first stirring blade 82 is fixedly installed on the first main rod 81 in the transverse direction and is located in the dosing tank 7. The second stirring blade 83 is arranged in a plurality of axially arranged along the first main rod 81. Each second stirring blade 83 is fixedly installed on the first main rod 81 in the transverse direction and is located in the dosing tank 7. The plurality of second stirring blades 83 are alternately arranged with the plurality of first stirring blades 82, and the length direction of the second stirring blade 83 is perpendicular to the length direction of the first stirring blade 82. The first stirring blade 82 and the second stirring blade 83 can rotate simultaneously with the rotation of the first main rod 81. The length direction of the second stirring blade 83 is perpendicular to the length direction of the first stirring blade 82, and the alternating arrangement can enhance the stirring effect.

[0042] The second stirring member 9 is located in the dosing tank 7 and is arranged to rotate around the outside of the first stirring member 8. The second stirring member 9 includes a second main rod 91 and a stirring frame 92. The lower end of the second main rod 91 extends into the dosing tank 7. The stirring frame 92 is fixedly arranged on the side wall of the second main rod 91 and is located in the dosing tank 7. The stirring frame 92 rotates with the rotation of the second main rod 91, which is conducive to rotating outside the first stirring member 8 while the first stirring member 8 rotates and stirs, thereby enhancing the stirring effect by performing multiple stirring methods simultaneously. A cleaning brush 14 or a scraper is provided in the vertical direction on the side wall of the stirring frame 92 away from the second main rod 91. The cleaning brush 14 or the scraper is used to contact the side wall of the dosing tank 7. When the second main rod 91 rotates, the side wall of the dosing tank 7 can be cleaned or scraped to avoid the phenomenon of drug sticking to the wall.

[0043] The first stirring member 8 and the second stirring member 9 rotate synchronously through the transmission mechanism 11. Specifically, the transmission mechanism 11 includes a mounting frame 111, a transmission ring 112, a driving gear 114 and a driven gear 115. The mounting frame 111 is fixedly arranged on the top of the dosing tank 7, the transmission ring 112 is fixedly arranged on the mounting frame 111, and a plurality of transmission teeth 113 are circumferentially arranged on the inner wall of the transmission ring 112. A motor 116 is fixedly arranged on the mounting frame 111. The driving gear 114 is rotatably arranged on the mounting frame 111 by the motor 116, and is located in the middle of the transmission ring 112 and is coaxially arranged with the transmission ring 112. The first main rod 81 is fixedly penetrated on the central axis of the driving gear 114. The driven gear 115 is rotatably arranged between the driving gear 114 and the transmission ring 112, and is meshed with the driving gear 114 and the transmission teeth 113. The second main rod 91 is fixedly penetrated on the driven gear 115.

[0044] An annular groove 12 is provided on the mounting frame 111, and annular baffles are fixedly provided on both sides of the opening of the annular groove 12. The top of the second main rod 91 passes through the driven gear 115 and extends into the annular groove 12. The top of the second main rod 91 is rotatably sleeved with a pulley 13, and the pulley 13 is rollingly set in the annular groove 12. Two baffles are blocked at the bottom of the pulley 13, so that when the driven gear 115 drives the second main rod 91 to rotate, the pulley 13 at the top of the second main rod 91 rolls in the annular groove 12, and is always located inside the annular groove 12 under the blocking of the baffle, thereby limiting the top of the second main rod 91, so that the second main rod 91 can rotate stably with the driven gear 115, ensuring the stability of the stirring of the second stirring member 9, and at the same time reducing friction through the rolling contact between the pulley 13 and the inner wall of the annular groove 12, which is practical and reliable.

[0045] During use of this embodiment, the flow rate of the dosing pump 3 is first set, and then the dosing pump 3 is started, and the agent in the medicine tank 1 is added to the dosing pool 7 through the dosing pipe 2 to mix with the wastewater. At this time, the first solenoid valve 4 is opened according to the flow rate requirement, and the second solenoid valve 6 is closed. At the same time, the flow rate in the dosing pipe 2 is recorded by the flow meter 10. At the same time, the agent can be continuously added to the medicine tank 1. The addition of the agent in the medicine tank 1 and the outflow of the agent through the dosing pipe 2 will cause the liquid level in the medicine tank 1 to change. As the liquid level in the medicine tank 1 continues to change, the second solenoid valve 6 is opened. At this time, the agent flows from the dosing pipe 2 and the reflux pipe 5 into the dosing pool 7 and the medicine tank 1 respectively. By adjusting the opening of the first solenoid valve 4 and the second solenoid valve 6, the flow rate displayed by the flow meter 10 is kept constant, thereby ensuring that the flow into the dosing pool 7 is constant and the dosing effect is guaranteed.

[0046] When the medicine in the medicine tank 1 is added to the medicine dosing tank 7 through the dosing tube 2 and mixed with the wastewater, the first stirring member 8 and the second stirring member 9 are stirred in the dosing tank 7 at the same time, thereby enhancing the mixing effect of the medicine and the wastewater and promoting the reaction between the medicine and the substances in the wastewater. Specifically, the motor 116 drives the driving gear 114 to rotate, thereby causing the first main rod 81 and the first stirring blade 82 and the second stirring blade 83 thereon to rotate with it. At the same time, the driving gear 114 drives the driven gear 115 to rotate. The driven gear 115, in cooperation with the driving gear 114 and the transmission teeth 113 on the transmission ring 112, revolves around the central axis of the driving gear 114 as the axis. At the same time, the driven gear 115 rotates around its central axis as the axis, thereby driving the second main rod 91 and the stirring frame 92 thereon to revolve and rotate around the periphery of the first stirring member 8, thereby enhancing the stirring effect.

[0047] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
