[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Example:

[0018] The accompanying drawings illustrate a specific embodiment of the automatic dosing device for defluorinating agents used to treat coal chemical wastewater according to this utility model. It mainly includes a wastewater treatment tank 1, with a wastewater inlet pipe 2 at the top of the wastewater treatment tank 1. Coal chemical wastewater is introduced into the wastewater treatment tank 1 through the wastewater inlet pipe 2. The wastewater treatment tank 1 is equipped with a stirring device inside to achieve a thorough mixing and reaction between the coal chemical wastewater and the defluorinating agent.

[0019] The wastewater treatment tank 1 is equipped with a chemical storage tank 3 on its top. The chemical storage tank 3 is connected to a first chemical dosing tank 4 and a second chemical dosing tank 5 via a first chemical dosing pump 6 and a second chemical dosing pump 7, respectively. The first chemical dosing tank 4 and the second chemical dosing tank 5 are of the same specifications. The first chemical dosing tank 4 and the second chemical dosing tank 5 are respectively equipped with a first water level sensor 8 and a second water level sensor 9.

[0020] The first dosing tank 4 is connected to a first metering tube A10 and a first metering tube B11. The heights of the first metering tubes A10 and B11 are the same as the height of the first dosing tank 4, but their capacities are different. The tops of the first dosing tank 4, the first metering tubes A10 and B11 are all open. The first metering tubes A10 and B11 are connected to the bottom of the first dosing tank 4, and a first flow valve A12 and a first flow valve B13 are respectively installed between the first metering tubes A10 and B11 and the first dosing tank 4.

[0021] The bottoms of the first metering tube A10 and the first metering tube B11 are respectively connected to the first dispensing tube A14 and the first dispensing tube B15. The connection between the bottom of the first metering tube A10 and the first dispensing tube A14 is provided with the first dispensing valve A16. The connection between the bottom of the first metering tube B11 and the first dispensing tube B15 is provided with the first dispensing valve B17. The first dispensing tubes A14 and B15 are inserted into the interior of the wastewater treatment tank 1.

[0022] The second dosing tank 5 is connected to a second metering tube A18 and a second metering tube B19. The heights of the second metering tubes A18 and B19 are the same as the height of the second dosing tank 5, but their capacities are different. The tops of the second dosing tank 5, the second metering tubes A18 and B19 are all open. The second metering tubes A18 and B19 are connected to the bottom of the second dosing tank 5. A second flow valve A20 and a second flow valve B21 are respectively installed between the second metering tubes A18 and B19 and the second dosing tank 5.

[0023] The bottoms of the second metering tubes A18 and B19 are respectively connected to the second dispensing tubes A22 and B23. A second dispensing valve A24 is provided at the connection between the bottom of the second metering tube A18 and the second dispensing tube A22. A second dispensing valve B25 is provided at the connection between the bottom of the second metering tube B19 and the second dispensing tube B23. The second dispensing tubes A22 and B23 are inserted into the interior of the wastewater treatment tank 1.

[0024] The first quantitative tube A10 and the second quantitative tube A18 have the same specifications, and the first quantitative tube B11 and the second quantitative tube B19 have the same specifications.

[0025] In practical operation, the defluoridating agent is stored in the storage tank 3. When one dosing tank is replenished, the other dosing tank adds a metered amount of agent to the wastewater treatment tank 1. When adding agent to the first dosing tank 4, the first dosing pump 6 draws the defluoridating agent from the storage tank 3 into the first dosing tank 4. At this time, the first flow valve A12 or the first flow valve B13 can be opened until the first water level sensor 8 detects a water level signal. Then, the first dosing pump 6 stops working and stops adding agent to the first dosing tank 4. At this time, the water level in the first metering tube A10 or the first metering tube B11 is the same as the water level in the first dosing tank 4. The same metering tube is used for each dosing. With the same quantity, after the first water level sensor 8 detects the water level signal and stops replenishing the agent, the first flow valve A12 or the first flow valve B13 closes, and the first outlet valve A16 or the first outlet valve B17 opens. A quantitative amount of agent is added to the wastewater treatment tank 1 through the first outlet pipe A14 or the first outlet pipe B15. Simultaneously with the addition of agent through the first outlet pipe A14 or the first outlet pipe B15, the second dosing pump 7 draws the defluoridating agent from the storage tank 3 into the second dosing tank 5. At this time, the second flow valve A12 can be opened. The second dosing pump 7 stops working and stops adding chemicals to the second dosing tank 5 after the second water level sensor 9 detects the water level signal, either through the second flow valve A20 or the second flow valve B21. At this time, the water level in the second metering pipe A18 or the second metering pipe B19 is the same as the water level in the second dosing tank 5. The second flow valve A20 or the second flow valve B21 is closed, and the second outlet valve A24 or the second outlet valve B25 is opened, adding chemicals quantitatively to the wastewater treatment tank 1 through the second outlet pipe A22 or the second outlet pipe B23. Similarly, while the second outlet pipe A22 or the second outlet pipe B23 is adding chemicals, the first dosing tank 4 is replenishing the chemicals. This cycle can achieve automatic and continuous dosing of defluoridating agent.

They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
