Description

Technical Field

[0001] This utility model relates to the field of sewage treatment technology, and in particular to a sewage treatment device for highway service areas. Background Technology

[0002] Highway service areas are places specifically designed for passengers and drivers to stop and rest, providing facilities such as parking lots, public restrooms, gas stations, vehicle repair shops, restaurants, and convenience stores. Due to the frequent flow of people and vehicles in highway service areas, water consumption is relatively high, resulting in continuous wastewater generation. To prevent wastewater discharge from polluting the environment, wastewater needs to be purified before being discharged.

[0003] A search revealed that Chinese Patent Publication No. CN213569928U discloses a wastewater treatment device for a highway service area. The device includes a wastewater storage tank, a first pump body, and a treatment tank. One end of the first pump body is connected to the wastewater storage tank via a first pipeline, and the other end is connected to the treatment tank via a second pipeline. An internal baffle plate divides the wastewater storage tank into a filter tank and a sedimentation tank. The baffle plate has through holes connecting the filter tank and the sedimentation tank. The filter tank has an inlet end, an opening channel, and a grid plate. One end of the grid plate abuts against the inner wall of the filter tank via parallel guide rails, and the other end is connected to the opening channel. The sedimentation tank has a first opening and a second opening at its top. The treatment tank has a third opening, a fourth opening, and an electrolytic mesh for ionizing and adsorbing heavy metals in the liquid medium to be treated. This device is rationally designed and facilitates wastewater treatment.

[0004] However, in the existing technology, flocculants and other agents are added to the wastewater during wastewater treatment. The flocculants adsorb and flocculate the particulate matter in the wastewater. However, the existing devices usually only have a device for stirring the wastewater and do not have a scraper or other mechanism on the inner wall of the treatment cylinder. As a result, the flocculated impurities and polymers are easy to stick to the inner wall of the treatment cylinder, making it inconvenient to clean the treatment cylinder later. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sewage treatment device for highway service areas. It aims to improve the current practice of adding flocculants and other agents to sewage for treatment. The flocculants adsorb and flocculate particulate matter in the sewage. However, existing devices usually only have a device for stirring the sewage and do not have scrapers or other mechanisms on the inner wall of the treatment cylinder. This causes the flocculated impurities and polymers to easily stick to the inner wall of the treatment cylinder, making subsequent cleaning of the treatment cylinder inconvenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a processing cylinder, characterized in that: a mounting frame is fixedly connected to the upper end of the processing cylinder; a motor is fixedly connected to one side of the upper end of the processing cylinder; a No. 3 bevel gear is rotatably connected to the upper end of the mounting frame; synchronous pulleys are fixedly connected to the upper end of the No. 3 bevel gear and the output end of the motor; a transmission belt is connected between the two synchronous pulleys; an input pipe is fixedly connected to one side of the upper end of the processing cylinder; a feeding pipe is fixedly connected to the other side of the upper end of the processing cylinder; a filter box is provided at the lower end of the processing cylinder; and a drive mechanism is provided inside the mounting frame.

[0007] As a further description of the above technical solution: When treating sewage, sewage can be fed into the treatment cylinder through the inlet pipe, and then the agent can be added into the treatment cylinder through the feeding pipe. Subsequently, the motor will drive one of the synchronous pulleys to rotate, and drive the other synchronous pulley to rotate through the transmission belt. At this time, the No. 3 bevel gear fixed to it can rotate accordingly and drive the rotating rod at the lower end to rotate. The rotating rod can drive the fixed rod inside the treatment cylinder to rotate, which in turn drives the scraper fixed at the end to move. The moving scraper will scrape off the impurities and polymers adhering to the inner wall of the treatment cylinder, so that they will not stick to the inner wall when discharged.

[0008] Preferably, a first bevel gear is rotatably connected to the lower part of the drive mechanism, and a second bevel gear is rotatably connected to one side of the mounting bracket. The outer surface of the first bevel gear meshes with the outer surface of the second bevel gear, and the outer surface of the second bevel gear meshes with the outer surface of the third bevel gear. A rotating rod is fixedly connected to the lower end of the third bevel gear.

[0009] As a further description of the above technical solution: the No. 3 bevel gear can drive the No. 2 bevel gear, which meshes with it, to rotate after rotating, thereby driving the No. 1 bevel gear to rotate.

[0012] Preferably, a fixing rod is fixedly connected to the lower end of the rotating rod, and a scraper is fixedly connected to one end of the fixing rod.

[0013] As a further description of the above technical solution: the rotating rod can drive the fixed rod to rotate after rotation, thereby driving the scraper to move.

[0014] Preferably, mounting rods are fixedly connected to both sides of the lower end of the rotating cylinder, and a toothed ring is fixedly connected to the upper part of the inside of the processing cylinder.

[0015] As a further description of the above technical solution: the rotating cylinder can drive the mounting rod to rotate after rotation, thereby driving the drive gear to move inside the toothed ring.

[0016] Preferably, one end of each of the two mounting rods is rotatably connected to a stirring rod, and the upper end of each of the two stirring rods is fixedly connected to a drive gear through one end of the two mounting rods, and the outer surfaces of the two drive gears respectively mesh with the inner surface of the toothed ring.

[0017] As a further description of the above technical solution: Since the outer surface of the movable drive gear meshes with the toothed ring, the drive gear can rotate after it is activated, thereby driving the stirring rod fixed at the lower end of the drive gear to revolve around the central axis while also rotating on its own axis.

[0018] Preferably, a support frame is fixedly connected to the upper end of the filter box, and the upper end of the support frame is fixedly connected to the upper end of the processing cylinder.

[0019] As a further description of the above technical solution: the support frame can be used to connect the treatment cylinder and the filter box.

[0020] Preferably, a liquid outlet pipe is fixedly connected to one side of the filter box, and a valve is fixedly connected to the lower end of the processing cylinder, with the lower end of the valve fixedly connected to the upper end of the filter box.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 5As shown, one embodiment of this utility model includes a processing cylinder 1. The processing cylinder 1 has a mounting frame 9 fixedly connected to its upper end, a motor 7 fixedly connected to one side of its upper end, a third bevel gear 11 rotatably connected to the upper end of the mounting frame 9, and synchronous pulleys 13 fixedly connected to both the upper end of the third bevel gear 11 and the output end of the motor 7. A transmission belt 14 drives between the two synchronous pulleys 13. An input pipe 6 is fixedly connected to one side of the upper end of the processing cylinder 1, and a feeding pipe 8 is fixedly connected to the other side of the upper end of the processing cylinder 1. A filter box 4 is located at the lower end of the processing cylinder 1. A drive mechanism is located inside the mounting frame 9, and the lower part of the drive mechanism is rotatably connected to... There is a first bevel gear 22, and a second bevel gear 10 is rotatably connected to one side inside the mounting bracket 9. The outer surface of the first bevel gear 22 meshes with the outer surface of the second bevel gear 10, and the outer surface of the second bevel gear 10 meshes with the outer surface of the third bevel gear 11. A rotating rod 12 is fixedly connected to the lower end of the third bevel gear 11. A rotating cylinder 18 is fixedly connected to the lower end of the first bevel gear 22. The outer surface of the rotating cylinder 18 is rotatably connected to the upper end of the processing cylinder 1. The outer surface of the rotating rod 12 is rotatably connected to the interior of the first bevel gear 22 and the interior of the rotating cylinder 18. A fixing rod 20 is fixedly connected to the lower end of the rotating rod 12, and a scraper 21 is fixedly connected to one end of the fixing rod 20.

[0033] In this embodiment, when treating wastewater, the wastewater is fed into the treatment cylinder 1 through the input pipe 6, and then the reagent is added into the treatment cylinder 1 through the feeding pipe 8. Subsequently, the motor 7 drives one of the synchronous pulleys 13 to rotate, and drives the other synchronous pulley 13 to rotate through the transmission belt 14. At this time, the No. 3 bevel gear 11 fixed to it can rotate accordingly and drive the rotating rod 12 at the lower end to rotate. The rotating rod 12 can drive the fixed rod 20 inside the treatment cylinder 1 to rotate, thereby driving the scraper 21 fixed at the end to move. The moving scraper 21 will scrape off the impurity polymers adhering to the inner wall of the treatment cylinder 1, so that they will not stick to the inner wall when discharged. In this way, when the device performs flocculation treatment on wastewater, the impurity polymers generated after flocculation can be scraped off by the scraper 21, avoiding polymers from sticking to the inside of the treatment cylinder 1, making the subsequent cleaning work of the device more convenient and the device more efficient.

[0034] Example 2, as Figures 1 to 5As shown, mounting rods 17 are fixedly connected to both sides of the lower end of the rotating cylinder 18. A toothed ring 15 is fixedly connected to the upper part of the inside of the processing cylinder 1. A stirring rod 19 is rotatably connected to one end of each of the two mounting rods 17. A drive gear 16 is fixedly connected to the upper end of each of the two stirring rods 19 through one end of each of the two mounting rods 17. The outer surfaces of the two drive gears 16 mesh with the inner surfaces of the toothed ring 15. A support frame 3 is fixedly connected to the upper end of the filter box 4. The upper end of the support frame 3 is fixedly connected to the upper end of the processing cylinder 1. A liquid outlet pipe 5 is fixedly connected to one side of the filter box 4. A valve 2 is fixedly connected to the lower end of the processing cylinder 1. The lower end of the valve 2 is fixedly connected to the upper end of the filter box 4.

[0035] In this embodiment, after the agent is added to the sewage, the motor 7 drives the third bevel gear 11 to rotate, and the second bevel gear 10, which meshes with the third bevel gear 11 on the side, will also rotate. This will drive the first bevel gear 22, which meshes with the second bevel gear 10, to rotate. The first bevel gear 22 can drive the rotating cylinder 18 to rotate, and drive the mounting rods 17 fixed on both sides to move. The moving mounting rods 17 will drive the drive gear 16 at its end to move. Since the outer surface of the moving drive gear 16 meshes with the toothed ring 15, the drive gear 16 can rotate after it moves. This will drive the stirring rod 19 fixed at the lower end of the drive gear 16 to revolve and rotate at the same time. In this way, when mixing sewage and agents, the stirring rod 19 can be used to fully stir the sewage and agents, making the mixing between the agents and sewage more thorough and efficient, and improving the efficiency of sewage treatment.

[0036] Working Principle: When treating wastewater, wastewater is fed into the treatment cylinder 1 through the inlet pipe 6, and then the reagent is added into the treatment cylinder 1 through the feed pipe 8. The motor 7 then drives one of the synchronous pulleys 13 to rotate, which in turn drives the other synchronous pulley 13 to rotate via the transmission belt 14. At this time, the fixed bevel gear 11 rotates accordingly, driving the lower rotating rod 12 to rotate. The rotating rod 12 drives the fixed rod 20 inside the treatment cylinder 1 to rotate, which in turn drives the scraper 21 fixed at the end to move. The moving scraper 21 scrapes away the impurities and polymers adhering to the inner wall of the treatment cylinder 1, preventing them from sticking to the inner wall during discharge. This method allows the device to remove the impurities and polymers generated after flocculation during wastewater treatment by scraping them away, preventing polymer adhesion to the treatment cylinder 1, making subsequent cleaning easier and the device more efficient. After the reagent is added to the wastewater, the motor 7... After the third bevel gear 11 rotates, the second bevel gear 10, which meshes with the third bevel gear 11 on the side, will also rotate, thereby driving the first bevel gear 22, which meshes with the second bevel gear 10, to rotate. The first bevel gear 22 can drive the rotating cylinder 18 to rotate, and drive the mounting rods 17 fixed on both sides to move. The moving mounting rods 17 will drive the drive gear 16 at its end to move. Since the outer surface of the moving drive gear 16 meshes with the toothed ring 15, the drive gear 16 can rotate after moving, thereby driving the stirring rod 19 fixed at the lower end of the drive gear 16 to revolve and rotate at the same time. In this way, when mixing sewage and chemicals, the stirring rod 19 can be set to fully stir the sewage and chemicals, making the mixing between the chemicals and sewage more thorough and efficient, and improving the efficiency of sewage treatment. After the sewage treatment is completed, the sewage can be injected into the filter box 4 by opening the valve 2 for subsequent sewage treatment.
