[0002] The wastewater triplex box is a very important device in the wet flue gas desulfurization wastewater treatment system. It is used to filter the wastewater generated by the cyclone of the gypsum dehydration system. It generally includes a neutralization zone, a sedimentation zone and a flocculation zone. Most triplex boxes now often add reagents at one time. The one-time addition of reagents is prone to problems such as too much or too little dosage, which leads to the situation that too much dosage cannot fully react with the sewage and too little dosage cannot achieve the treatment effect, thereby reducing the effect of wastewater treatment.

However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0027] like Figures 1 to 5 A triple-tank device for treating desulfurization wastewater is shown, comprising three tanks 1, which are respectively configured as a neutralization tank, a sedimentation tank and a flocculation tank, and can perform different treatments on wastewater. A connecting block 2 is connected between every two tanks 1, and the two connecting blocks 2 are respectively connected to the two connected tanks 1, so that the wastewater entering one of the tanks 1 will pass through the connecting block 2 and enter the other tanks 1 for other treatment processes. A liquid inlet for the wastewater to enter is provided on one side of the tank 1 on one side, and a liquid outlet for the wastewater to be discharged is provided on one side of the tank 1 on the other side.

[0028] A hydraulic cylinder 16 is fixedly provided on one side of the top surface of the two connecting blocks 2, and the piston rods of the two hydraulic cylinders 16 are fixedly provided with an inverted L-shaped baffle 17. The bottom surfaces of the two baffles 17 penetrate the connecting block 2 and press against the bottom surface of the inner cavity of the connecting block 2. When the baffle 17 presses against the bottom surface of the inner cavity of the connecting block 2, the space between the two boxes 1 can be isolated. After the wastewater enters one of the boxes 1 and is processed, the hydraulic cylinder 16 is opened to drive the baffle 17 to move upward, so that the wastewater can pass through the space opened by the baffle 17 and enter the other box 1 for other processing steps.

[0029] A metering bucket 3 is provided on one side of each box body 1, and each metering bucket 3 is fixed on one side of the box body 1 through a fixed block. A transverse plate 7 is fixedly provided on the inner side wall of the metering bucket 3 in the transverse direction, and a through groove 8 for the medicine to pass through is penetrated through the top surface of the transverse plate 7. A groove 4 is provided on the bottom surface of the metering bucket 3, and a volume box 5 is provided in the inner cavity of the groove 4 to be slidably matched therewith. The inner wall and the peripheral wall of the volume box 5 are in frictional contact with the inner wall of the groove 4. A connecting pipe 6 is connected to the bottom surface of the volume box 5, and a valve can be installed on the peripheral side of the connecting pipe 6. The free end of the connecting pipe 6 is connected to the peripheral side of the box body 1. A bottom plate 11 is fixedly provided on one side surface of the box body 1 and located below the volume box 5. A cylinder 12 is fixedly provided on the top surface of the bottom plate 11, and the piston rod of the cylinder 12 is passed through the bottom plate 11. A fixed plate is arranged on one side of the volume box 5, and the cylinder 12 is turned on, so that the cylinder 12 drives the volume box 5 to move in the inner cavity of the groove 4 through the fixed plate, thereby changing the space between the volume box 5 and the horizontal plate 7. At this time, the medicine liquid to be administered is administered into the quantitative bucket 3, and the medicine liquid will pass through the through groove 8 into the space between the volume box 5 and the horizontal plate 7. When the space is filled, the valve is opened so that the medicine liquid can move along the connecting pipe 6 into the box body 1, so that the medicine liquid is mixed with the wastewater to achieve the effect of quantitative administration of the medicine liquid. A transparent partition and scale markings may be provided on one side of the volume box 5 and the quantitative bucket 3 to facilitate the adjustment of the space between the volume box 5 and the horizontal plate 7 to match the required amount of medicine.

[0030] A transverse groove 9 is provided on one side wall of the through groove 8, and the transverse groove 9 is connected with the through groove 8. The inner cavities of the through groove 8 and the transverse groove 9 are provided with an adaptive limiting plate 10. One side of the transverse groove 9 penetrates to one side of the transverse plate 7, and one side of the limiting plate 10 penetrates to one side of the quantitative bucket 3, and one side of the quantitative bucket 3 is provided with a rectangular groove for the limiting plate 10 to pass through. After the space between the volume box 5 and the transverse plate 7 is filled, the limiting plate 10 is pushed to move the limiting plate 10 in the inner cavity of the transverse groove 9 and move to the inner cavity of the through groove 8, and the peripheral side wall of the limiting plate 10 is pressed against the inner side wall of the through groove 8, so that the limiting plate 10 is pressed against the through groove 8 is used to limit the medicine below the horizontal plate 7 and the medicine above it, so as to avoid the situation where the medicine between the volume box 5 and the horizontal plate 7 is transported to the inside of the box body 1 through the connecting pipe 6, and the medicine above the horizontal plate 7 will also move into the box body 1. When it is necessary to quantify the medicine first, the limit plate 10 can be pulled to move the limit plate 10 from the through groove 8 to the inner cavity of the horizontal groove 9, so that the medicine can pass through the through groove 8 for quantification, avoiding the situation of excessive or insufficient dosage of medicine, thereby improving the effect of wastewater treatment, and the setting of multiple quantitative buckets 3 can quantitatively dose different medicines or flocculants.

[0031] A driving motor 13 is fixedly arranged on the top surface of each box body 1, and the output shaft of each driving motor 13 passes through the box body 1 and is connected to a rotating shaft 14, and a plurality of mixing rods 15 are fixedly arranged at equal intervals on the circumference of each rotating shaft 14. After the wastewater and the reagent are put into the box body 1, the driving motor 13 is turned on, so that the driving motor 13 can drive the rotating shaft 14 and the mixing rod 15 to rotate, so as to mix the wastewater and the reagent.

[0032] The rotating shaft 14 and the mixing rod 15 for mixing the liquid medicine and the wastewater in the box 1, as well as the baffle 17 for separating the box 1, can be set to the existing technical structure, and it is only necessary to ensure that the wastewater entering the box 1 and the quantitative liquid medicine can be mixed.

[0033] Working principle:

[0034] The triple-box device for desulfurization wastewater treatment puts wastewater into the box body 1 through the liquid inlet, and then turns on the cylinder 12, allowing the cylinder 12 to drive the volume box 5 to move longitudinally through the fixed plate, so that the space between the volume box 5 and the horizontal plate 7 is adapted to the amount of medicine required to be put in. At this time, the medicine for wastewater treatment is put into the quantitative bucket 3, and the medicine is allowed to fall into the volume box 5 through the through groove 8, and the medicine is allowed to fill the space between the volume box 5 and the horizontal plate 7. When the space is filled, the limit plate 10 is pushed to move the limit plate 10 in the inner cavity of the horizontal groove 9 and enter the inner cavity of the through groove 8, so that the limit plate One side of 10 can be against the inner wall of one side of the through groove 8, so that the limit plate 10 can limit the through groove 8, so that the medicine in the delivery box 1 can be quantified to avoid excessive or insufficient delivery of medicine, thereby improving the effect of wastewater treatment. At this time, the valve is opened to allow the medicine between the volume box 5 and the cross plate 7 to be delivered into the box 1, and mixed by driving the motor 13, the rotating shaft 14 and the mixing rod 15. After one treatment process is completed, the baffle 17 can be driven by the hydraulic cylinder 16 to move upward, so that the wastewater can pass through the connecting block 2 into another box 1 for treatment.
