Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment agent mixing device for sewage treatment. Background Art

[0002] During the sewage treatment process, since it contains a large amount of difficult-to-degrade substances, it cannot be effectively removed by a single water treatment equipment. Therefore, in many cases, it is necessary to reasonably add sewage treatment chemicals according to the particularity of sewage quality so that the treated sewage meets the national emission standards.

[0003] At present, the Chinese utility model with the publication number of CN218307311U discloses a sewage treatment agent mixing device for sewage treatment, including a mixing box and a feed box, the feed box is connected to the top of the mixing box, a crushing mechanism is installed on the feed box, and a mixing mechanism is installed on the mixing box, the crushing mechanism includes a crushing motor and a crushing roller, two crushing rollers are rotatably connected in the feed box, the two crushing rollers are connected by gear transmission, the crushing motor is fixedly installed on the outside of the feed box, and the output end of the crushing motor is connected to one end of one of the crushing rollers through a coupling. The sewage treatment agent mixing device for sewage treatment, solid medicine for sewage treatment is put into the feed box, the crushing motor starts to mobilize the crushing roller to rotate, the two crushing rollers are connected by gear transmission, the two crushing rollers rotate to crush the solid medicine, and the crushed medicine is easy to mix and dissolve in water, which improves the mixing efficiency to a certain extent.

[0004] The existing reagent mixing device generally puts the reagent into the sewage treatment tank from a pipe or a feeding port on one side. This method of adding reagents is difficult to quickly and fully mix with the sewage, and it takes a long time to stir the sewage, resulting in low sewage treatment efficiency. At the same time, after the sewage is treated, since the sewage contains a large amount of impurities, it is not only easy to clog the drain pipe, but also difficult to separate the relatively clean sewage at the top from the turbid sewage at the bottom with more impurities, which is not convenient for subsequent differentiated treatment of different sewage. Utility Model Content

[0005] The utility model aims to provide a sewage treatment agent mixing device for sewage treatment, which has the advantages of improving the mixing efficiency of the agent and sewage and facilitating the separation of relatively clean sewage, thereby reducing the subsequent treatment procedures of this part of sewage.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a sewage treatment agent mixing device for sewage treatment, comprising a sewage tank, a motor is bolted to the top of the sewage tank, a first gear is fixedly connected to the output end of the motor, stirring rods are rotatably connected to both sides of the interior of the sewage tank, a second gear meshing with the first gear is fixedly sleeved on the top of the stirring rod, a connecting groove is provided inside the stirring rod, through holes communicating with the connecting groove are provided on both sides of the surface of the stirring rod, adding ports are fixedly installed on both sides of the top of the sewage tank, a sliding joint slidably connected to the adding port is fixedly connected to the top of the stirring rod, the connecting groove is communicated with the interior of the adding port through the sliding joint, a fixed pipe is fixedly connected to the bottom of the inner cavity of the sewage tank, a drainage pipe connected to the fixed pipe is fixedly connected to the bottom of the sewage tank, a telescopic pipe is slidably connected to the interior of the fixed pipe, an air bag is fixedly connected to the top of the telescopic pipe, and drainage holes are provided on both sides of the top of the telescopic pipe.

[0007] With the above technical solution, the agent enters the inside of the connection tank from the dosing port during the rotation of the stirring rod driven by the motor. Then it is evenly dispersed from the through holes at different positions and mixed with the sewage by stirring with the stirring rod. Thereby, the mixing effect of the agent and the sewage is improved, and the sewage treatment efficiency is improved; the buoyancy of the airbag in the sewage drives the telescopic tube to slide upward, so that the drainage hole is always kept below the sewage liquid level, so that the relatively clean sewage on the top is discharged through the drainage pipe. In turn, the subsequent treatment process of this part of the sewage can be reduced, reducing the sewage treatment cost.

[0008] The utility model is further configured as follows: a dosing pipe connected with two dosing ports is arranged on the top of the sewage tank, and a water inlet valve and a drain valve are fixedly connected to one side of the top and the bottom of the sewage tank that are away from each other.

[0009] By adopting the above technical solution, the reagent can be added to the two adding ports at the same time through the dosing pipe, and the turbid sewage in the sewage tank can be discharged by opening the drain valve for separate treatment.

[0010] The utility model is further configured as follows: both sides of the top of the stirring rod surface are fixedly connected with a defoaming rake.

[0011] By adopting the above technical solution, the defoaming rake can be driven to remove the bubbles on the sewage surface during the rotation of the stirring rod.

[0012] The utility model is further configured as follows: an observation window is fixedly connected to one side of the surface of the sewage tank.

[0013] The adoption of the technical solution makes it easy to observe the sewage treatment situation inside the sewage tank.

[0014] The utility model is further configured as follows: sealing rings that are slidably connected to each other are bonded between the sliding joint and the adding port, and between the fixed pipe and the telescopic pipe.

[0015] The above technical solution is adopted to improve the sealing performance and avoid leakage.

[0016] The utility model is further configured as follows: the insides of the through holes and the drainage holes are both fixedly connected with filter screens.

[0017] The above technical solution is used to filter the impurities suspended in the sewage.

[0018] The utility model is further configured as follows: a limit plate is fixedly sleeved on the surface of the telescopic tube.

[0019] By adopting the above technical solution, the sliding position of the telescopic tube is limited, so that the telescopic tube is stuck on the top of the fixed tube.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. Driven by the motor, during the rotation of the stirring rod, the reagent enters the inside of the connecting tank from the dosing port. Then it is evenly dispersed from the through holes at different positions and mixed with the sewage through the stirring rod. This improves the mixing effect of the reagent and sewage and improves the sewage treatment efficiency.

[0022] 2. The buoyancy of the airbag in the sewage drives the telescopic tube to slide upward, so that the drainage hole is always kept below the sewage level, so that the relatively clean sewage on the top can be discharged through the drainage pipe. This can reduce the subsequent treatment process of this part of sewage and reduce the cost of sewage treatment. BRIEF DESCRIPTION OF THE DRAWINGS

When the stirring rod 4 is driven by the motor 2 to rotate, the agent enters the inside of the connecting groove 6 from the feeding port 9. Then it is evenly dispersed from the through holes 7 at different positions and mixed with the sewage by stirring the stirring rod 4. Thereby, the mixing effect of the agent and the sewage is improved, and the sewage treatment efficiency is improved.

[0031] refer to Figure 1 , Figure 2 The top of the sewage tank 1 is provided with a dosing pipe 14 connected to the two dosing ports 9, and the top and bottom sides of the sewage tank 1 that are away from each other are fixedly connected with a water inlet valve 16 and a drain valve 17. The dosing pipe 14 can be used to simultaneously add chemicals to the two dosing ports 9, and the drain valve 17 can be opened to discharge the turbid sewage in the sewage tank 1 for separate treatment.

[0032] refer to Figure 2 , both sides of the top of the stirring rod 4 are fixedly connected with a defoaming rake 15. The defoaming rake 15 can be driven to knock out the bubbles on the sewage surface during the rotation of the stirring rod 4.

[0033] refer to Figure 1 An observation window 19 is fixedly connected to one side of the surface of the sewage tank 1. It is convenient to observe the sewage treatment situation inside the sewage tank 1.

[0034] Brief description of the use process: Turn on the motor 2 to drive the first gear 3 to rotate, so that the first gear 3 and the second gear 5 are meshed, thereby driving the stirring rod 4 to rotate to stir the sewage inside the sewage tank 1. Then add the medicine through the addition port 9, and the stirring rod 4 drives the sliding joint 8 to rotate at the bottom of the addition port 9 during the rotation process, but maintains communication with the inside of the addition port 9. Therefore, the medicine can enter the inside of the connecting groove 6 through the addition port 9, and then during the rotation process of the stirring rod 4, the medicine is evenly dispersed from the through holes 7 at different positions, and mixed with the sewage through the stirring rod 4.

[0035] Embodiment 2:

[0036] refer to Figure 1 , Figure 2 , Figure 4 A sewage treatment agent mixing device for sewage treatment, wherein a fixed pipe 10 is fixedly connected to the bottom of the inner cavity of a sewage tank 1, a drain pipe 18 connected to the fixed pipe 10 is fixedly connected to the bottom of the sewage tank 1, a telescopic pipe 11 is slidably connected inside the fixed pipe 10, an air bag 13 is fixedly connected to the top of the telescopic pipe 11, and drain holes 12 are opened on both sides of the top of the telescopic pipe 11. The buoyancy of the air bag 13 in the sewage drives the telescopic pipe 11 to slide upward, so that the drain hole 12 is always kept below the sewage liquid level, so that the relatively clean sewage on the top is discharged through the drain pipe 18. This can reduce the subsequent treatment process of this part of the sewage and reduce the sewage treatment cost.

[0037] refer to Figure 2 , Figure 3 A sealing ring 20 is bonded between the sliding joint 8 and the injection port 9 and between the fixed pipe 10 and the telescopic pipe 11 to improve the sealing performance and avoid leakage.

[0040] Brief description of the use process: The buoyancy of the airbag 13 in the sewage drives the telescopic tube 11 to slide upward on the top of the fixed tube 10, so that the sewage can enter the inside of the telescopic tube 11 from the drainage hole 12, and finally be discharged from the drainage pipe 18 at the bottom through the fixed tube 10. Since the fixed tube 10 can isolate the sewage at the bottom, after the sediment is deposited at the bottom, the turbid sewage cannot be directly discharged through the drainage pipe 18, while the cleaner sewage at the top can be discharged through the drainage hole 12. At the same time, the airbag 13 floats on the water surface, so that the drainage hole 12 is submerged below the water surface, and impurities floating on the water surface will not enter the inside of the telescopic tube 11.
