Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an energy-saving integrated sewage treatment device. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. The water after sewage treatment will be used for non-drinking purposes such as greening, flushing, and supplementing ornamental water bodies, enabling the water to be recycled and effectively reducing waste of water resources.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN213707941U discloses an energy-saving integrated sewage treatment device for industrial use, including a tank body. A sewage discharge channel is provided at the lower end of the tank body, a tank cover is hinged at the upper end of the tank body, a water inlet hopper is provided at the upper end of the tank cover, a buffer tank is provided at the lower end of the tank cover, a through port is provided on the buffer tank, an annular block is provided inside the tank body, a clamping block is in contact connection with the upper end of the annular block, a filter tank is provided at the lower end of the clamping block, a neutralization tank is provided below the filter tank, and the neutralization tank is arranged on the inner wall of the tank body. First, the sewage is filtered, then fully mixed with the sewage treatment agent, and then purified by activated carbon particles, facilitating the full treatment of the sewage; the device can take out the filter tank for cleaning by opening the tank cover, and then take out the filter plate for cleaning. The bolts on the connecting plate can be unscrewed, and the water passing frame can be pulled out through the connecting plate, facilitating the replacement of the activated carbon particles in the water passing frame.

[0004] The above mechanism treats the sewage through activated carbon particles and cleans the filter plate by taking it out, thus completing the overall sewage treatment. However, in the actual use process, before sewage treatment, a grille is needed to preliminarily filter large-particle impurities in the sewage. The grille is prone to blockage when in contact with large-particle impurities for a long time. If not cleaned synchronously during the filtration process in a timely manner, excessive impurities will cause the sewage to be unable to enter the interior of the treatment tank. Content of the Utility Model

[0005] The purpose of the utility model is to provide an energy-saving integrated sewage treatment device to solve the problem that before sewage treatment, a grille is needed to preliminarily filter large-particle impurities in the sewage, and the grille is prone to blockage when in contact with large-particle impurities for a long time as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An energy-saving integrated sewage treatment device, including a treatment tank, wherein a plurality of partition plates are fixedly connected inside the treatment tank, a sedimentation tank is arranged on one side inside the treatment tank, an aeration component is arranged on one side of the sedimentation tank inside the treatment tank, and a membrane separation component is snap-connected inside the treatment tank on one side of the aeration component. One side of the top of the treatment tank is installed with a water inlet through bolts;

[0007] A grille body is snap-connected to the lower end inside the water inlet, and a grille cleaning mechanism for cleaning the grille body is arranged inside the water inlet above the grille body. The grille cleaning mechanism includes a rotating shaft, and the rotating shaft is rotatably connected to one end between the water inlets. A fan blade is fixedly connected to the outer side of the rotating shaft. Both ends of the rotating shaft extend to the outside of the water inlet and are rotatably connected to a threaded rod through a pulley. A movable block is threadedly connected to the outer side of the threaded rod, and an installation box is fixedly connected to the top end of the movable block. A cleaning brush is fixedly connected to the bottom end of the installation box through a connecting spring, and the bottom end of the cleaning brush is attached to the top end of the grille body;

[0008] A driving motor is fixedly connected to the other side of the top of the treatment tank, and a disinfection stirring mechanism for disinfecting the water body is arranged inside the treatment tank at one end of the driving motor.

[0009] Furthermore, the cross-section of the water inlet is in an inverted "L" shape, and the fan blade is arranged at the corner of the water inlet.

[0010] Furthermore, a connecting spring is fixedly connected to the top end inside the installation box, and the installation box and the cleaning brush form an elastic structure through the connecting spring.

[0011] Furthermore, both sides of the movable block are slidably connected to the water inlet through connecting rods, and the movable block is arranged below the fan blade.

[0012] Furthermore, the disinfection stirring mechanism includes a rotating rod, and the rotating rod is fixedly connected to both ends on one side inside the treatment tank.

[0015] 1. When sewage enters the interior of the treatment tank through the water inlet, it needs to pass through the grid body for preliminary filtration to separate large-particle impurities from the water body. When filtering large-particle impurities, it is easy to cause the grid body to become blocked.

[0016] Furthermore, when the sewage enters the interior of the water inlet, it continuously impacts the fan blades, causing the fan blades and the rotating shaft to rotate due to the impact of the sewage and driving the threaded rod to rotate through the pulley.

[0017] Even further, when the fan blades are washed by the sewage, they will rotate. Utilizing the rotation of the fan blades can increase the flow rate of the water entering the interior of the water inlet, enabling the sewage to enter the treatment tank interior for treatment more quickly.

[0018] 2. The interior of the dosing box is separated by a limiting plate. The disinfectant to be dosed is placed between the inner sides of the limiting plate.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1:

[0031] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8The described technical solution is to solve the problem that before sewage treatment, a grille is needed to preliminarily filter large particle impurities in the sewage, and the grille is prone to blockage when in contact with large particle impurities for a long time: The energy-saving integrated sewage treatment equipment discloses a grille cleaning mechanism, including a treatment tank 1. A plurality of partition plates 3 are fixedly connected inside the treatment tank 1. A sedimentation tank 4 is arranged on one side inside the treatment tank 1. An aeration component 5 is arranged on one side of the sedimentation tank 4 inside the treatment tank 1. And a membrane separation component 6 is snap-connected inside the treatment tank 1 on one side of the aeration component 5. One side of the top of the treatment tank 1 is installed with a water inlet 2 through bolts. The lower end inside the water inlet 2 is snap-connected with a grille body 7. And a grille cleaning mechanism for cleaning the grille body 7 is arranged inside the water inlet 2 above the grille body 7. The grille cleaning mechanism includes a rotating shaft 9, and the rotating shaft 9 is rotatably connected to one end between the water inlets 2. A fan blade 8 is fixedly connected to the outside of the rotating shaft 9. Both ends of the rotating shaft 9 extend to the outside of the water inlet 2 and are rotatably connected with a threaded rod 10 through a pulley. A movable block 20 is threadedly connected to the outside of the threaded rod 10. And the top of the movable block 20 is fixedly connected with a mounting box 11. The bottom end of the mounting box 11 is fixedly connected with a cleaning brush 13 through a connecting spring 12. And the bottom end of the cleaning brush 13 is in contact with the top end of the grille body 7. The cross-section of the water inlet 2 is in an inverted "L" shape, and the fan blade 8 is arranged at the corner of the water inlet 2. The top end inside the mounting box 11 is fixedly connected with a connecting spring 12. And the mounting box 11 and the cleaning brush 13 form an elastic structure through the connecting spring 12. Both sides of the movable block 20 form a sliding structure with the water inlet 2 through connecting rods. And the movable block 20 is arranged below the fan blade 8.

[0032] In this example, the sewage enters the inside of the treatment tank 1 through the water inlet 2. And the inside of the treatment tank 1 is divided into multiple different spaces by the partition plates 3. The sewage first enters the inside of the sedimentation tank 4. The sedimentation tank 4 is used to sediment the sewage, so that small particle impurities in the sewage can be sedimented inside the sedimentation tank 4. The relatively clear sewage in the upper layer enters the anaerobic tank. The aeration component 5 is used to aerate the sewage. Then the sewage enters the membrane bioreactor. The membrane separation component 6 is used to react and treat the sewage. Finally, the sewage enters the inside of the disinfection tank. And finally, the disinfected water body can be discharged for secondary utilization.

[0033] When the sewage enters the inside of the treatment tank 1 through the water inlet 2, it needs to pass through the grille body 7 for preliminary filtration to separate large-particle impurities from the water body. When filtering large-particle impurities, it is easy to cause the grille body 7 to become blocked. When the sewage enters the inside of the water inlet 2, it continuously impacts the fan blade 8, causing the fan blade 8 to be pushed by the sewage and rotate continuously. As a result, the fan blade 8 and the rotating shaft 9 rotate due to the impact of the sewage and drive the threaded rod 10 to rotate through the pulley. During the rotation of the threaded rod 10, it can drive the movable block 20 to move, causing the movable block 20 to drive the lower mounting box 11 and the cleaning brush 13 to move on the surface of the grille body 7, shifting the blocked large-particle impurities to one side, effectively preventing the large-particle impurities from blocking the grille body 7, and enabling the grille body 7 to stably filter and convey sewage before regular cleaning.

[0034] Embodiment 2:

[0035] As Figures 1-4 shown in the technical solution, to solve the problem that the last step of sewage treatment is usually disinfection, and it is easy to have problems with the inconvenient control of the dosage of the disinfection agent during the disinfection process: The energy-saving integrated sewage treatment equipment discloses a quantitative dosing mechanism. One end of the top of the treatment tank 1 is provided with a quantitative dosing mechanism for disinfectant dosing. The quantitative dosing mechanism includes a dosing box 17, and the dosing box 17 is fixedly connected to one end of the top of the treatment tank 1. A limiting plate 18 is rotatably connected inside the dosing box 17, and the limiting plate 18 is connected to the driving motor 14 through a pulley. A plurality of feed ports 19 are opened at the bottom of the dosing box 17. The bottom end of the limiting plate 18 is slidably connected to the dosing box 17, and the length of the limiting plate 18 is less than the length of the inner side of the dosing box 17.

[0036] In this example, during the process of the water body entering the disinfection tank for treatment, the output end of the driving motor 14 drives the pulley to rotate, and the pulley drives the limiting plate 18 to rotate. The inside of the dosing box 17 is separated by the limiting plate 18. The disinfectant to be dosed is placed between the inner sides of the limiting plate 18. When the limiting plate 18 is driven to rotate, the disinfectant can be dialed, so that the disinfectant can fall into the inside of the disinfection tank through the feed port 19 and the conduit, enabling the disinfectant to come into contact with the water body and disinfect the water body, making the water body safer.

[0037] Embodiment 3:

[0038] As Figures 1-5The technical solution shown, based on Embodiment 2, is to solve the problem that the contact between the disinfection agent and the water body is not thorough enough, resulting in insufficient disinfection of some water bodies: The energy-saving integrated sewage treatment equipment discloses a disinfection stirring mechanism. On the other side of the top of the treatment tank 1, a driving motor 14 is fixedly connected, and inside the treatment tank 1 at one end of the driving motor 14, there is a disinfection stirring mechanism for disinfecting the water body. The disinfection stirring mechanism includes a rotating rod 16, and the rotating rod 16 is fixedly connected to both ends on one side inside the treatment tank 1. A plurality of stirring rods 15 are fixedly connected to the outer side of the rotating rod 16, and the stirring rods 15 are symmetric about the vertical central axis of the rotating rod 16.

[0039] In this example, when the output end of the driving motor 14 rotates, it will drive the lower stirring rods 15 and the rotating rod 16 to rotate through a pulley. The two groups of stirring rods 15 and the rotating rod 16 rotate in a staggered manner, so as to stir and mix the disinfectant and the water body inside the disinfection tank, making the disinfection of the water body more thorough.
