Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device. Background Art

[0002] Filtration devices in wastewater treatment are key equipment for removing suspended particulate matter from wastewater. These devices purify the water by intercepting solid particles, organic matter, and other impurities in the water using filter screens or filter media of varying pore sizes. Filtration is a crucial component of the physical treatment process in modern wastewater treatment technology, helping to improve water quality, reduce pollutant emissions, and protect the environment.

[0003] my country's utility model patent publication number CN 221797094 U discloses a sewage treatment device that drives the circular metal filter to rotate by impacting it with water flow from a sewage pipe, thereby achieving an anti-clogging effect on the circular metal filter. However, when the water flow impacts the circular metal filter, the gravity distribution on the circular metal filter is not much different. Therefore, the circular metal filter rotates slowly and may even be unable to rotate due to the small water flow, resulting in a poor anti-clogging effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a sewage treatment device.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A sewage treatment device comprises a tank body and a circular metal filter screen, wherein a partition is provided in the tank body to separate the tank body into a sewage area and a sludge area; the sludge area is provided with a drainage pipe, and the sludge area is provided with a sewage pipe; the upper parts of both sides of the tank body are fixedly connected to a frame, a rotating shaft is provided at the midline of the circular metal filter screen, the rotating shaft is fixedly connected to the circular metal filter screen through a support rod group, and the two ends of the rotating shaft are rotatably connected to the corresponding frame and are arranged at an angle; the inner surface of the circular metal filter screen is evenly distributed with a plurality of baffles extending in the radial direction; a sewage pipe extending into one side of the upper side of the circular metal filter screen is provided at the higher end of the rotating shaft, and the sewage pipe is fixedly connected to the frame thereby through a bracket; the water outlet end of the sewage pipe is bent to point to the surface of the circular metal filter screen and does not interfere with the trajectory of the inner edge of the baffle.

[0007] Preferably, a roller is provided in the sludge area below the end of the circular metal filter, the roller is rotatably connected to the pool body, a plurality of crushing knives are provided on the surface of the roller, a reduction motor is fixedly connected to the outside of the pool body, and the output end of the reduction motor is fixedly connected to the corresponding end of the roller.

[0008] Preferably, a mounting plate is fixedly connected to the outer side of the pool body, and the reduction motor is mounted on the mounting plate.

[0009] Preferably, the inclination angle of the rotating shaft is 10-15°.

[0010] Preferably, the baffle is a flat plate or an arc-shaped plate.

[0011] Preferably, a splash guard is provided at the upper end of the sludge area.

[0012] The above technical solution has the following advantages:

[0013] This utility model incorporates multiple baffles on the inner surface of the circular metal filter. When positioned on one side of the sewage pipe, these baffles effectively absorb the impact of the falling water flow and the weight of the water, significantly increasing the differential weight acting on the circular metal filter. The key to this design is that it ensures that even with low water flow, the circular metal filter receives sufficient power to maintain its normal rotation, effectively preventing the circular metal filter from becoming immobilized due to insufficient water flow, thereby improving the overall system's operating efficiency and stability.

A partition 3 is provided in the tank body 1 to separate the tank body 1 into a sewage area 4 and a sludge area 5; the sludge area 5 is provided with a drainage pipe 6, and the sludge area 5 is provided with a sewage pipe 7; the upper part of both sides of the tank body 1 is fixedly connected with a frame 18, and a rotating shaft 19 is provided at the center line of the circular metal filter screen 2. The rotating shaft 19 is fixedly connected to the circular metal filter screen 2 through a support rod group 8, and the two ends of the rotating shaft 19 are connected to the corresponding The frame 18 is rotatably connected and inclined; a plurality of baffles 9 extending in the radial direction are evenly distributed on the inner surface of the circular metal filter screen 2; a sewage pipe 10 extending into the upper part of the circular metal filter screen 2 is provided at the higher end of the rotating shaft 19, and the sewage pipe 10 is fixedly connected to the frame 18 at this location by a bracket 11; the water outlet end of the sewage pipe 10 is bent to point to the surface of the circular metal filter screen 2, and does not interfere with the trajectory 12 of the inner edge of the baffle 9, and the water flow can fall onto the baffle 9 located below by inertia.

[0023] As a further improvement to this embodiment, a roller 13 is disposed within the sludge zone 5, below the end of the circular metal filter 2. The roller 13 is rotatably connected to the tank body 1. A plurality of crushing blades 14 are disposed on the surface of the roller 13. A reduction motor 15 is fixedly connected to the outside of the tank body 1, and the output end of the reduction motor 15 is fixedly connected to the corresponding end of the roller 13. The reduction motor 15 drives the roller 13 to rotate, allowing the sludge on the circular metal filter 2 to be crushed by the crushing blades 14, facilitating its discharge and subsequent processing.

[0024] As a specific technical solution of this embodiment, a mounting plate 16 is fixedly connected to the outer side of the cell body 1 , and the reduction motor 15 is mounted on the mounting plate 16 to facilitate the disassembly, assembly and maintenance of the reduction motor 15 .

The present invention ensures that even when the water flow is low, the circular metal filter 2 can obtain sufficient power to maintain its normal rotation, thereby effectively avoiding the problem of the circular metal filter 2 being stagnant due to insufficient water flow.
