[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] according to Figure 1 , 2 As shown in Figure 3, a phloroglucinol production wastewater treatment device is proposed in this embodiment, including a sedimentation tank 1 and a dosing tank 2, the dosing tank 2 is connected to the sedimentation tank 1, and three stirring rods 6 and two baffles 14 are arranged in the dosing tank 2, the two baffles 14 separate the three stirring rods 6 and divide three mutually connected stirring chambers in the dosing tank 2; the phloroglucinol production wastewater is injected into the dosing tank 2 through the wastewater pipe, and the sewage treatment agent passes through, and the two baffles 14 divide three stirring chambers in the dosing tank 2, and the drug-containing wastewater injected into the dosing tank 2 will flow into the next stirring chamber after entering the first stirring chamber and overflowing, until it flows out of the dosing tank 2 and enters the sedimentation tank 1 for the next step of treatment. A sewage outlet 15 is arranged at the lower end of the dosing tank 2, and the sewage outlet 15 is connected to each stirring chamber, and the sewage remaining in the stirring chamber is discharged through the sewage outlet 15.

[0022] A fixed plate 3 is provided at the upper end of the dosing tank 2, and the fixed plate 3 is fixedly connected to the dosing tank 2. A movable plate 4 is provided above the fixed plate 3, and a driving assembly for controlling the rotation of the stirring rod 6 is installed on the movable plate 4. Three through holes 7 are opened on the fixed plate 3, and each stirring rod 6 passes through each through hole 7 respectively; the movable plate 4 is arranged above the fixed plate 3, and the driving assembly is installed on the movable plate 4, which is used to control each stirring rod 6 to stir in the stirring chamber. The multi-chamber structural design enables the stirring rod 6 to be in contact with the fast-flowing wastewater for a long time, thereby improving the mixing effect between the drug and the sewage.

[0023] Lifting components for adjusting the height of the movable plate 4 are provided on both sides of the dosing tank 2, and the lifting components are detachably connected to the movable plate 4. Since the driving component is installed on the movable plate 4, when the lifting component controls the height of the movable plate 4, the height of the driving component and the stirring rod 6 will also be adjusted accordingly. The stirring rod 6 expands its stirring range by moving up and down, further improving the uniformity of the mixing of the drug and the wastewater, and improving the sewage treatment effect.

[0024] More specifically, an overflow port 12 is provided on the side of the dosing tank 2 close to the sedimentation tank 1. The sedimentation tank 1 is connected to the dosing tank 2 through the overflow port 12. The sewage overflowing from the last stirring chamber will be injected into the sedimentation tank 1 through the overflow port 12. In order to reduce the fluctuations caused by the injection of sewage into the sedimentation tank 1, an overflow weir 13 is provided on the inner side of the sedimentation tank 1. The overflow weir 13 is placed below the overflow port 12, and the overflow port 12 is fixedly connected to the inner wall of the sedimentation tank 1. When a large amount of water flows into the sedimentation tank 1 through the overflow port 12, the overflow weir 13 can slow down the speed of the water flow through its designed slope or step structure, reduce the fluctuations caused by the injection of sewage, avoid direct impact on the bottom or side wall of the sedimentation tank 1, and reduce erosion and damage to the tank structure.

[0025] About the driving assembly: the driving assembly includes three motors 5, the motors 5 are fixedly connected to the upper end of the movable plate 4, and the output end of the motor 5 passes through the movable plate 4 and is fixedly connected to the upper end of the stirring rod 6. The rotation of the stirring rod 6 is controlled by the motor 5, and the mounting end of the motor 5 is fixedly connected to the upper end of the movable plate 4. When the motor 5 is started, the stirring rod 6 will be driven to rotate, and the stirring rod 6 will stir the sewage in the dosing tank 2 during the rotation.

[0026] About the lifting assembly: The lifting assembly includes a pneumatic push rod 10 arranged on both sides of the dosing tank 2. The mounting end of the pneumatic push rod 10 is detachably connected to the dosing tank 2 through a mounting bolt 11. A triangular bracket 8 is provided at the output end of the mounting bolt 11. One end of the triangular bracket 8 is fixedly connected to the mounting bolt 11, and the other end of the triangular bracket 8 is detachably connected to both sides of the movable plate 4 through a bolt fixing. A slot that cooperates with the mounting bolt 11 is provided on the outside of the dosing tank 2. When the pneumatic push rod 10 is removed from the outside of the dosing tank 2, the mounting bolt 11 can be unscrewed from the slot. The height of the movable plate 4 is controlled by the pneumatic push rod 10. When the pneumatic push rod 10 pushes the triangular bracket 8 to rise, the movable plate 4 will also rise under the drive of the triangular bracket 8.

[0027] More specifically, the bolt fixing member includes a plurality of fixing bolts 9 assembled on the triangular bracket 8, and the fixing bolts 9 pass through the triangular bracket 8 and are threadedly connected to the mounting holes 16 opened on both sides of the movable plate 4. Similarly, the triangular bracket 8 is also fixed to the movable plate 4 by bolt connection, so that the staff can remove the upgrade component for replacement and maintenance.

[0028] In order to improve the stability of the movable plate 4 when it rises and falls, a limit rod 17 is provided at the upper end of the baffle 14. The limit rod 17 is fixedly connected to the baffle 14. The upper end of the limit rod 17 penetrates the fixed plate 3 and the movable plate 4. The fixed plate 3 and the movable plate 4 are both slidably connected to the limit rod 17. When the movable plate 4 is lifted and lowered driven by the lifting assembly, it slides along the limit rod 17. The limit rod 17 cooperates with the movable plate 4 to guide the movable plate 4, ensuring that the stirring rod 6 connected to the lower end of the movable plate 4 can rise and fall vertically along the fixed plate 3.

[0029] When the pneumatic push rod 10 pulls the movable plate 4 to fall completely, the lower end surface of the movable plate 4 will contact the upper end surface of the fixed plate 3. In order to reduce the impact of the rapid fall of the movable plate 4 on the fixed plate 3 and the movable plate 4, a rubber pad 18 is provided at the lower end of the movable plate 4. The rubber pad 18 is placed above the fixed plate 3 and is fixedly connected to the movable plate 4. When the movable plate 4 falls completely, the rubber pad 18 at the lower end surface of the movable plate 4 will first contact the upper end surface of the fixed plate 3. The rubber pad 18 shrinks by deformation to buffer the force acting on the movable plate 4, thereby protecting the movable plate 4, the drive assembly and the upgrade assembly.

[0030] The working principle of the present application: the wastewater produced by phloroglucinol is injected into the dosing tank 2 through the wastewater pipe, and the sewage treatment agent passes through. The two baffles 14 divide the dosing tank 2 into three stirring chambers. After the drug-containing wastewater injected into the dosing tank 2 enters the first stirring chamber and overflows, it will flow into the next stirring chamber until it flows out of the dosing tank 2 and enters the sedimentation tank 1 for the next step of treatment. The drive assembly is installed on the movable plate 4 to control each stirring rod 6 to stir in the stirring chamber. The multi-chamber structural design enables the stirring rod 6 to be in contact with the fast-flowing wastewater for a long time, thereby improving the mixing effect between the drug and the sewage. The height of the stirring rod 6 is adjustable, and the stirring rod 6 expands its stirring range by moving up and down, further improving the uniformity of the mixing of the drug and the wastewater, and improving the sewage treatment effect.
