However, in the treatment process of existing flotation technology, the incorrect location of adding drugs and the unsatisfactory effect of the mixing link between the agent and the wastewater will lead to the phenomenon of no scum in the flotation tank, unsatisfactory reaction effect of the flotation tank and low treatment efficiency.

[0030] The utility model embodiment provides a flotation tank dosing pipeline, such as Figure 1-Figure 2 As shown, the flotation tank dosing pipeline is used for connecting the intermediate tank, the dosing tank and the flotation tank, and includes:
[0031] A first liquid inlet pipeline 110 and a second liquid inlet pipe 120, wherein the first liquid inlet pipeline 110 is connected to the dosing tank, and the second liquid inlet pipe 120 is connected to the intermediate tank; an end of the first liquid inlet pipeline 110 away from the dosing tank is connected to the second liquid inlet pipe 120;
[0032] A main pipeline 300, a gas-liquid mixing pump 220 is provided at the end of the pipeline of the second liquid inlet pipe 120, the main pipeline 300 is connected to the outlet of the gas-liquid mixing pump 220, and the end of the main pipeline 300 away from the gas-liquid mixing pump 220 is connected to the flotation tank;
[0033] The main pipeline 300 is provided with a plurality of pipeline mixers in sequence; the chemical agent in the dosing tank is mixed with the dissolved gas water delivered by the first liquid inlet pipeline 110 and the second liquid inlet pipe 120, and is uniformly delivered to the flotation tank by the gas-liquid mixing pump 220 through the main pipeline 300;
[0034] In this embodiment, the intermediate tank, the dosing tank and the flotation tank are all prior art. The intermediate tank stores dissolved air water, and the chemical agent in the dosing tank is added to the dissolved air water before the dissolved air water reaches the gas-liquid mixing pump 220. The chemical agent and the dissolved air water are pressurized by the gas-liquid mixing pump 220 and then sent to the main pipeline 300. Under the action of the pipeline mixer, the chemical agent and the dissolved air water are fully mixed. The intermediate tank, the dosing tank and the flotation tank are prior art. This application mainly utilizes the advance mixing of the agent and the dissolved air water. The purpose of this is to allow the agent and the water to merge in advance before entering the flotation tank, thereby reducing the time for the agent and the water to be mixed and integrated. When the agent mixed into the water enters the flotation tank, it directly contacts the impurities in the aqueous solution in the flotation tank and is easier to combine, thereby improving the reaction effect and improving the treatment efficiency of the flotation tank.
[0035] Meanwhile, in the present application, a branch pipeline is provided on the main pipeline 300, and the branch pipeline helps several groups of pipeline mixers to achieve a multi-stage or single-stage mixing effect. The purpose of using several groups of different pipeline mixers to mix with branch pipelines is to meet the purpose of different mixing effects, while ensuring the mixing effect, shortening the mixing time and reducing the need for the output power of the gas-liquid mixing pump 220, thereby reducing the operating cost of the equipment;
[0036] As a preferred implementation in this embodiment, the branch pipeline includes a first branch pipeline 410 and a second branch pipeline 420; a plurality of groups of pipeline mixers are respectively a first pipeline mixer 310, a second pipeline mixer 320 and a third pipeline mixer 330, and the first pipeline mixer 310, the second pipeline mixer 320 and the third pipeline mixer 330 constitute a pipeline mixer module;
[0037] The first pipeline mixer 310, the second pipeline mixer 320 and the third pipeline mixer 330 are sequentially connected in series on the main pipeline 300;
[0038] One end of the first branch pipeline 410 is connected to the main pipeline 300 between the first pipeline mixer 310 and the second pipeline mixer 320, and the other end is connected to the main pipeline 300 between the third pipeline mixer 330 and the flotation tank; a first three-way valve 510 is provided at the connection point between the first branch pipeline 410 and the main pipeline 300 between the first pipeline mixer 310 and the second pipeline mixer 320, and the first three-way valve 510 helps the mixed liquid output by the gas-liquid mixing pump 220 to directly skip the second pipeline mixer 320 and the third pipeline mixer 330;
[0039] One end of the second branch pipeline 420 is connected to the main pipeline 300 between the second pipeline mixer 320 and the third pipeline mixer 330, and the other end is connected to the main pipeline 300 between the third pipeline mixer 330 and the flotation tank; a second three-way valve 520 is provided at the connection point between the second branch pipeline 420 and the main pipeline 300 between the second pipeline mixer 320 and the third pipeline mixer 330, and the second three-way valve 520 helps the mixed liquid output by the gas-liquid mixing pump 220 to directly skip the third pipeline mixer 330;
[0040] In this embodiment, the mixed liquid output from the gas-liquid mixing pump 220 has three modes in total:
[0041] In the first mode, the first three-way valve 510 closes the port connected to the first branch pipeline 410, and the second three-way valve 520 closes the port connected to the second branch pipeline 420, so that the mixed liquid output by the gas-liquid mixing pump 220 can only pass through the first pipeline mixer 310, the second pipeline mixer 320 and the third pipeline mixer 330 in sequence along the main pipeline 300 and finally reach the flotation tank;
[0042] The second mode is that the first three-way valve 510 closes the port connected to the first branch pipeline 410, and the second three-way valve 520 closes the port connected to the main pipeline 300, and opens the port connected to the second branch pipeline 420; in this way, the mixed liquid output by the gas-liquid mixing pump 220 will stop moving along the main pipeline 300 after passing through the first pipeline mixer 310 and the second pipeline mixer 320 in sequence, and will instead move along the second branch pipeline 420 to the main pipeline 300 located at the rear end of the third pipeline mixer 330, so that the third pipeline mixer 330 will be skipped to reduce the mixing process;
[0043] In the third mode, the first three-way valve 510 closes the port connected to the main pipeline 300 and opens the port connected to the first branch pipeline 410. The mixed liquid output by the gas-liquid mixing pump 220 flows along the main pipeline 300 through the first pipeline mixer 310 and directly enters the first branch pipeline 410 to reach the main pipeline 300 located at the rear end of the third pipeline mixer 330, thus skipping the second pipeline mixer 320 and the third pipeline mixer 330.
[0044] The first branch pipeline 410, the second branch pipeline 420, the first three-way valve 510 and the second three-way valve 520 cooperate to realize the conversion between single-stage and multi-stage mixing, improve the mixing effect and grading effect of the dosing pipeline of the flotation tank, adapt to different agents through different mixing effects, ensure the mixing effect while reducing the occurrence of excessive mixing energy loss, and avoid energy waste;
[0045] In this embodiment, check valves are respectively provided at the outlets of the second pipeline mixer 320 and the third pipeline mixer 330 to prevent the liquid from flowing back into the second pipeline mixer 320 and the third pipeline mixer 330 during the mixing process;
[0046] As a preferred implementation in this embodiment, a dosing pump 210 is provided on the first liquid inlet pipeline 110, and the dosing pump 210 mainly adds chemicals to the second liquid inlet pipe 120; a check valve is provided on the second liquid inlet pipe 120 between the connection point between the first liquid inlet pipeline 110 and the second liquid inlet pipe 120 and the intermediate tank, and the check valve here prevents the chemical from flowing back into the intermediate tank;
