Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a device suitable for simultaneous nitrogen and phosphorus removal from wastewater. Background Technology

[0002] Wastewater is typically generated from domestic, industrial, and agricultural activities, containing large amounts of organic matter such as nitrogen and phosphorus. If these organic substances are not treated, they can cause significant harm to water bodies. Nitrogen and phosphorus removal technology is an effective method for treating wastewater. During the treatment process, biological methods are used to convert nitrogen and phosphorus in the wastewater into nitrogen gas and oxygen, achieving the effect of purifying the wastewater. Wastewater nitrogen and phosphorus removal technology plays a crucial role in modern water treatment. By treating wastewater for nitrogen and phosphorus removal, we can protect the aquatic environment, conserve water resources, improve water quality, and reduce the impact of wastewater on the ecological environment, thus achieving the goal of sustainable development.

[0003] In wastewater denitrification and phosphorus removal systems, over time, impurities, microbial metabolites, and precipitates generated during the denitrification and phosphorus removal process in the wastewater will adhere to the inner wall of the treatment tank. This fouling not only reduces the effective volume of the equipment but also provides additional attachment sites for microorganisms, which may lead to microbial imbalance and reduce denitrification and phosphorus removal efficiency. Existing cleaning methods still rely on regular manual cleaning, which is labor-intensive, inefficient, and impractical.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a device suitable for simultaneous nitrogen and phosphorus removal from wastewater, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a device suitable for simultaneous nitrogen and phosphorus removal from wastewater, including a treatment tank, an inlet pipe and an outlet pipe installed at the upper end of the treatment tank, a stirring assembly installed inside the treatment tank, a cleaning assembly installed on the stirring assembly, and a locking assembly installed at the upper end of the treatment tank.

[0008] The stirring assembly is used to stir the wastewater poured into the treatment tank so that the wastewater can be fully denitrified and dephosphorized. The clockwise rotation of the stirring assembly can drive the cleaning assembly to rotate so that the cleaning assembly can perform cleaning operations on the inside of the treatment tank. The locking assembly is used to ensure that the cleaning assembly can only rotate in one direction.

[0009] Furthermore, the stirring assembly includes a motor, which is mounted on the top of the processing tank. A rotating rod is mounted on the motor shaft, and the rotating rod is aligned with the shaft of the processing tank. Several stirring rods are mounted on the rotating rod.

[0010] Furthermore, the cleaning assembly includes a one-way bearing, which is fixedly mounted on the rotating rod. A connecting rod is mounted on the one-way bearing, and a rotating column is rotatably mounted on one end of the connecting rod. Several brushes are evenly mounted on the rotating column, and each brush can contact the inner wall of the treatment tank.

[0011] Furthermore, a toothed ring is installed on the inner wall of the processing tank, and a rotating gear is installed on the upper end of the rotating column, the rotating gear meshing with the toothed ring.

[0012] Furthermore, the locking assembly includes a housing mounted on top of the processing tank, a wedge block slidably mounted inside the housing, one side of the wedge block being an inclined surface, and a spring installed inside the housing, the upper end of the spring contacting the inner wall of the housing, and the lower end of the spring contacting the upper surface of the wedge block.

[0013] Furthermore, a water supply pipe is installed at the upper end of the treatment tank, and a drainage pipe is installed at the lower end of the treatment tank, with a valve installed on the drainage pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses a stirring component to drive a cleaning component to rotate. The cleaning component repeatedly rubs against the inner wall of the treatment tank, thereby removing the dirt attached to the inner wall of the treatment tank. This allows the device to clean the inner wall of the treatment tank automatically, eliminating the need for regular manual cleaning and maintenance of the tank interior. This saves manpower, improves efficiency, and ensures that the inner wall of the treatment tank will no longer be covered with dirt, thus avoiding affecting the denitrification and phosphorus removal treatment of wastewater.

[0016] 2. This utility model installs a rotating gear on the upper end of the rotating column and a toothed ring on the inner wall of the treatment tank. When the connecting rod drives the rotating column to rotate, the rotating gear meshes with the toothed ring, causing the rotating gear to rotate. The rotation of the rotating gear drives the rotating column and the brush to rotate. During the rotation of the brush, the contact angle between the brush and the inner wall of the treatment tank changes continuously, enabling a more comprehensive and meticulous cleaning of the inner wall of the treatment tank. This comprehensively improves the cleaning effect of the cleaning component on the inner wall of the treatment tank, ensuring the cleaning quality of the treatment tank and the normal operation of subsequent wastewater denitrification and phosphorus removal treatment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a device suitable for simultaneous nitrogen and phosphorus removal from wastewater, including a treatment tank 1. The upper end of the treatment tank 1 is equipped with an inlet pipe 2 and an outlet pipe 3. The inside of the treatment tank 1 is equipped with a stirring assembly 4. A cleaning assembly 5 is installed on the stirring assembly 4. A locking assembly 6 is installed on the upper end of the treatment tank 1.

[0030] The stirring component 4 is used to stir the sewage poured into the treatment tank 1 so that the sewage can be fully denitrified and dephosphorized. The clockwise rotation of the stirring component 4 can drive the cleaning component 5 to rotate so that the cleaning component 5 can perform cleaning operations on the inside of the treatment tank 1. The locking component 6 is used to ensure that the cleaning component 5 can only rotate in one direction.

[0031] In practical use, wastewater is fed into treatment tank 1 via inlet pipe 2 for simultaneous denitrification and phosphorus removal. Counterclockwise activation of stirring component 4 ensures thorough contact between nitrogen, phosphorus, and other organic matter in the wastewater and the biological and chemical substances involved in the denitrification and phosphorus removal reaction within treatment tank 1, achieving complete denitrification and phosphorus removal and improving treatment efficiency and quality. After treatment, the treated wastewater is discharged through outlet pipe 3, meeting discharge requirements and protecting the ecological environment. When significant amounts of dirt adhere to the inside of treatment tank 1, clockwise rotation of stirring component 4 activates cleaning components within the tank, thus removing impurities. The cleaning component repeatedly rubs against the inner wall of the treatment tank 1, thus removing the dirt attached to the inner wall of the treatment tank 1. The locking component 6 prevents the cleaning component from rotating when the stirring component 4 rotates counterclockwise to stir the sewage inside the treatment tank 1. This ensures that the stirring component 4 can only drive the cleaning component to rotate and clean the inner wall of the treatment tank 1 when it rotates clockwise, avoiding increased power consumption. This solves the problems of high labor intensity, low efficiency, and low practicality of existing manual cleaning methods, improves the cleaning efficiency and service life of the treatment tank 1, and ensures the stable operation of the sewage denitrification and phosphorus removal treatment system.

[0032] This invention uses a stirring component 4 to drive a cleaning component to rotate. The cleaning component repeatedly rubs against the inner wall of the treatment tank 1, thus removing the dirt attached to the inner wall of the treatment tank 1. This allows the device to clean the inner wall of the treatment tank 1 automatically, eliminating the need for regular manual cleaning and maintenance of the inside of the treatment tank 1. This saves manpower, improves efficiency, and ensures that the inner wall of the treatment tank 1 will not be covered with dirt, thus avoiding affecting the denitrification and phosphorus removal treatment of wastewater.

[0033] In one embodiment, the stirring assembly 4 includes a motor 7, which is mounted on the top of the processing tank 1. A rotating rod 8 is mounted on the shaft of the motor 7, and the rotating rod 8 is aligned with the shaft of the processing tank 1. A plurality of stirring rods 9 are mounted on the rotating rod 8.

[0034] When it is necessary to remove nitrogen and phosphorus from wastewater, the drive motor 7 can be used to drive the rotating rod 8 to rotate counterclockwise. The rotation of the rotating rod 8 drives the stirring rod 9 to rotate, thereby cutting and pushing the wastewater, causing the wastewater to flow in different directions and at different speeds. This breaks the static state of the wastewater and promotes the full mixing and contact of various substances in the wastewater, thereby achieving full nitrogen and phosphorus removal treatment.

[0035] In one embodiment, the cleaning assembly 5 includes a one-way bearing 10, which is fixedly mounted on the rotating rod 8. A connecting rod 11 is mounted on the one-way bearing 10, and a rotating column 12 is rotatably mounted on one end of the connecting rod 11. A plurality of brushes 13 are evenly mounted on the rotating column 12, and each brush 13 can contact the inner wall of the treatment tank 1.

[0036] When cleaning of the inner wall of the treatment tank 1 is required, the motor 7 can be driven to rotate the rotating rod 8 clockwise. Since the one-way bearing 10 is fixedly installed on the rotating rod 8, according to the characteristics of the one-way bearing 10, it will allow itself to rotate smoothly when it receives power in the clockwise direction, thereby transmitting the power to the connecting rod 11, driving the connecting rod 11 to rotate, thereby driving the rotating column 12 installed at one end of the connecting rod 11 to rotate, and begin to move in a circle along the inner wall of the treatment tank 1. Then, the brush 13 on the rotating column 12 repeatedly scrapes the inner wall of the treatment tank 1, scraping away the dirt attached to the inner wall of the treatment tank 1 little by little. This allows the device to clean the inner wall of the treatment tank 1 automatically, eliminating the need for manual periodic cleaning and maintenance of the inside of the treatment tank 1.

[0037] In one embodiment, for the above-mentioned processing tank 1, a toothed ring 14 is installed on the inner wall of the processing tank 1, and a rotating gear 15 is installed on the upper end of the rotating column 12, and the rotating gear 15 meshes with the toothed ring 14.

[0038] By installing a rotating gear 15 on the upper end of the rotating column 12 and a toothed ring 14 on the inner wall of the treatment tank 1, when the connecting rod 11 drives the rotating column 12 to rotate, the rotating gear 15 meshes with the toothed ring 14, causing the rotating gear 15 to rotate. The rotation of the rotating gear 15 drives the rotating column 12 and the brush 13 to rotate. During the rotation of the brush 13, the contact angle between the brush 13 and the inner wall of the treatment tank 1 changes continuously, which can more comprehensively and meticulously clean the inner wall of the treatment tank 1. This comprehensively improves the cleaning effect of the cleaning component 5 on the inner wall of the treatment tank 1, ensuring the cleaning quality of the treatment tank 1 and the normal operation of subsequent wastewater denitrification and phosphorus removal treatment.

[0039] In one embodiment, the locking component 6 includes a housing 16, which is mounted on the top of the processing tank 1. A wedge 17 is slidably mounted inside the housing 16, with one side of the wedge 17 being an inclined surface. A spring 18 is installed inside the housing 16, with the upper end of the spring 18 contacting the inner wall of the housing 16 and the lower end of the spring 18 contacting the upper surface of the wedge 17.

[0040] The inclined block 17 can block the connecting rod 11, so that when the rotating rod 8 drives the stirring rod 9 to stir the sewage in the treatment tank 1, the connecting rod 11 cannot rotate counterclockwise with the rotating rod 8. The connecting rod 11 is blocked by the inclined block 17, so that the entire cleaning assembly will not rotate with the rotating rod 8. When cleaning is required, the drive motor 7 drives the rotating rod 8 to rotate clockwise, which drives the connecting rod 11 to rotate through the one-way bearing 10. When the connecting rod 11 contacts the inclined surface of the inclined block 17, the contact compresses the spring 18, causing the inclined block 17 to retract into its housing 16. Thus, the inclined block 17 can only make the connecting rod 11 rotate clockwise for cleaning, and will not move with the rotating rod 8 counterclockwise. This reduces the power consumption of the device and improves its practicality.

[0041] In one embodiment, for the above-mentioned treatment tank 1, a water supply pipe 19 is installed at the upper end of the treatment tank 1, a drainage pipe 20 is installed at the lower end of the treatment tank 1, and a valve 21 is installed on the drainage pipe 20.

[0042] The water supply pipe 19 can deliver cleaning water to the treatment tank 1 during the cleaning operation, thereby improving the cleaning effect. After the cleaning operation is completed, the drain pipe 20 can be activated by operating the valve 21 to create a smooth channel in the drain pipe 20, allowing the cleaning water and the cleaned dirt to be discharged outside the treatment tank 1 for appropriate disposal. In addition, the valve 21 can ensure that untreated sewage will not seep outside from the drain pipe 20 during the denitrification and phosphorus removal process.

[0043] Through the above technical solution, 1. The stirring component 4 drives the cleaning component to rotate, and the cleaning component repeatedly rubs against the inner wall of the treatment tank 1, thereby removing the dirt attached to the inner wall of the treatment tank 1. This allows the device to automatically clean the inner wall of the treatment tank 1, eliminating the need for regular manual cleaning and maintenance, saving manpower, improving efficiency, and ensuring that the inner wall of the treatment tank 1 will not accumulate dirt, thus avoiding affecting the denitrification and phosphorus removal treatment of wastewater; 2. By installing a rotating gear 15 on the upper end of the rotating column 12 and a gear ring 14 on the inner wall of the treatment tank 1, when continuous... When the connecting rod 11 drives its rotating column 12 to rotate, the rotating gear 15 meshes with its gear ring 14, causing the rotating gear 15 to rotate. The rotation of the rotating gear 15 drives the rotating column 12 and the brush 13 to rotate. During the rotation of the brush 13, the contact angle between the brush 13 and the inner wall of the treatment tank 1 changes continuously, which can more comprehensively and meticulously clean the inner wall of the treatment tank 1. This comprehensively improves the cleaning effect of the cleaning component 5 on the inner wall of the treatment tank 1, ensuring the cleaning quality of the treatment tank 1 and the normal operation of subsequent wastewater denitrification and phosphorus removal treatment.
