[0002] Aeration devices are a core component of wastewater treatment, acting as akin to "artificial lungs." Simply put, their primary function is to inject air into the wastewater, increasing dissolved oxygen levels. This creates suitable conditions for aerobic microorganisms that feed on organic pollutants in the wastewater, breaking them down into harmless carbon dioxide and water through their metabolism, thus purifying the water.

[0003] Patent CN222907670U discloses a process device for improving wastewater treatment capacity, including a wastewater aeration tank, a temperature-regulating aeration mechanism, a dust filtration mechanism, a transverse movement mechanism, and a sludge cleaning mechanism. A temperature-regulating aeration mechanism extending into the wastewater aeration tank is installed on one side, and the dust filtration mechanism is connected to it. A transverse movement mechanism is installed on the top of the wastewater aeration tank, and a sludge cleaning mechanism extending into the bottom of the tank is installed on it. This invention facilitates wastewater aeration and treatment, allows for easy adjustment of wastewater temperature based on weather conditions to maintain high bacterial activity and increase the rate of organic matter decomposition. It also facilitates the cleaning of sludge deposited in the wastewater.

[0004] The inventors have discovered at least the following problems in the prior art: The existing wastewater treatment process can clean the settled sludge, but during the cleaning process, the downward air jets from the aeration pipes cause the settled sludge to remix with the wastewater. In addition, the large proportion of wastewater in the sludge during the sludge cleaning process results in a large sludge volume, which not only increases the difficulty and transportation cost of subsequent sludge treatment, but also reduces the actual efficiency of sludge cleaning operations.

[0005] Therefore, this solution provides a process device to improve wastewater treatment capacity, thereby solving the above-mentioned problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a process device to improve the sewage treatment capacity, so as to solve the problems in the existing technology that the aeration effect during the sludge cleaning process will cause the settled sludge to be resuspended, and the cleaned sludge has a high water content and large volume, resulting in low treatment efficiency.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: A process device for improving wastewater treatment capacity includes a treatment mechanism and an aeration mechanism. The treatment mechanism is equipped with an air jet mechanism inside and two centrally symmetrical cleaning mechanisms are arranged around the treatment mechanism.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] According to the appendix Figure 1 - Figure 5 As shown, this utility model provides a process device for improving sewage treatment capacity, including a treatment mechanism 1 and an aeration mechanism 2. The treatment mechanism 1 is equipped with an air jet mechanism 3 inside, and two centrally symmetrical cleaning mechanisms 4 are arranged around the treatment mechanism 1. The treatment mechanism 1 includes a treatment tank 11, with discharge troughs 12 at both ends of the treatment tank 11 and sliding grooves 13 on both sides of the treatment tank 11. The output end of the aeration mechanism 2 is connected to an air jet pipe 31. The jet mechanism 3 includes a jet pipe 31 and downwardly inclined guide rings 34 evenly distributed at the bottom of the jet pipe 31; The cleaning mechanism 4 includes a cleaning box 41 fixedly connected to the periphery of the treatment pool 11. One end of the cleaning box 41 is provided with a one-way sludge pushing component 46, the other end of the cleaning box 41 is provided with an auger plate 48, and the outside of the cleaning box 41 is equipped with a drive motor 47. The treatment unit 1 and the aeration unit 2 constitute a sewage treatment tank in the prior art where the aeration temperature can be controlled at a constant temperature.

[0022] In a further embodiment, a chute 42 is provided on the side of the cleaning box 41 near the treatment pool 11. A screw 45 is rotatably connected inside the chute 42. A compression chamber 43 is provided inside one end of the cleaning box 41. The chute 42 and the compression chamber 43 are respectively connected to the sliding groove 13 and the discharge groove 12. A filter screen 44 is installed inside the compression chamber 43.

[0023] In this embodiment, the filter screen 44 occupies half of the compression chamber 43, and the other half is used for sludge entry; the cleaning box 41 and the treatment tank 11 are integrated; the drive motor 47 is L-shaped, and the slide 42 and the compression chamber 43 are both inside it.

[0024] In a further embodiment, the unidirectional mud-pushing assembly 46 includes a sliding frame 461 and a push plate 463 rotatably connected inside the sliding frame 461. A barrier plate 464 is fixedly connected to the bottom of the inner side of the sliding frame 461, and the barrier plate 464 cooperates with the push plate 463.

[0025] In this embodiment, the length of the sliding frame 461 is half the length of the compression chamber 43, which is used to push the sludge in half of the bottom area of ​​the treatment tank 11, so that the two cleaning mechanisms 4 can handle all the sludge as a whole; the obstruction of the barrier plate 464 makes the push plate 463 form a one-way opening and closing plate, so that when the one-way sludge pushing assembly 46 moves to the compression chamber 43 of the other cleaning box 41, the sludge can pass through the sliding frame 461.

[0026] In a further embodiment, a sliding seat 462 is fixedly connected to the outer side of the sliding frame 461. The sliding seat 462 passes through the sliding groove 13 and is slidably connected inside the sliding groove 42. The sliding seat 462 is threadedly connected by a screw 45.

[0027] In this embodiment, the rotation of the screw 45 allows the sliding seat 462 and the sliding frame 461 to move back and forth, thereby allowing the one-way sludge pushing assembly 46 to push the sludge into the interior of the compression chamber 43.

[0028] In a further embodiment, the output end of the drive motor 47 is provided with a drive shaft 471, the auger plate 48 is fixedly connected to the periphery of the drive shaft 471, a second bevel gear 472 is installed on the periphery of the drive shaft 471, the drive shaft 471 is perpendicular to the screw 45, one end of the screw 45 is fixedly connected to a first bevel gear 451, and the first bevel gear 451 meshes with the second bevel gear 472.

[0029] In this embodiment, when the drive shaft 471 rotates, the auger blades 48 can continuously transport the sludge, thereby continuously compressing the sludge inside the compression chamber 43. During compression, the water in the sludge will be discharged through the filter screen 44, thereby reducing the volume of the sludge.

[0030] In a further embodiment, a discharge port is provided at the bottom of the cleaning box 41, and a mud discharge gate 49 is installed at the discharge port.

[0031] In this embodiment, the sludge discharge gate 49 can be extracted after the sludge is compressed, thereby discharging it.

[0032] In a further embodiment, the bottom of the jet pipe 31 is provided with evenly distributed jet heads 32, the top of the lower inclined guide ring 34 is fixedly connected with a connecting post 33, the connecting posts 33 are all fixedly connected below the jet heads 32, and the lower periphery of the lower inclined guide ring 34 is fixedly connected with an upper inclined guide ring 35.

[0033] In this embodiment, the jet nozzle 32 can spray air downwards, preventing sludge from entering the jet nozzle 32 during sedimentation. The lower inclined guide ring 34 and the upper inclined guide ring 35 guide the sludge so that it cannot be sprayed towards the sedimented sludge, thus preventing disturbance to the already sedimented sludge.

[0034] The working principle of this utility model is as follows: When treating wastewater, airflow can be injected into the interior of each jet mechanism 3 through the aeration mechanism 2, and the gas temperature can be controlled in real time during injection. When the airflow enters the interior of the jet pipe 31, it will be ejected from the connecting column 33 at its bottom, so that the airflow first contacts the surface of the lower inclined guide ring 34 and spreads to the surroundings. Then, guided by the upper inclined guide ring 35, the airflow will be tilted upward, thereby avoiding disturbing the settled sludge. When the sludge settled at the bottom needs to be treated, the drive motor 47 can be driven to operate. After the meshing transmission of bevel gear 2 472 and bevel gear 1 451, the mutually perpendicular drive shaft 471 and screw 45 will both rotate. The rotation of drive shaft 471 will cause the auger plate 48 to rotate continuously, and the rotation of screw 45 will cause the one-way sludge pushing assembly 46 to move back and forth at the bottom of treatment tank 11, thereby pushing the sludge into the compression chamber 43, so that the auger plate 48 can continuously compress the sludge. During compression, the wastewater in the sludge will pass through filter screen 44 and return to the interior of treatment tank 11. In this way, not only can the sludge be treated, but it can also be compressed to remove its water content and reduce its volume, thereby facilitating transportation.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
