Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an efficient and energy-saving aeration device for wastewater treatment. Background Technology
[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. In wastewater treatment processes, microorganisms are used to degrade the organic matter in the wastewater to achieve preliminary treatment. A crucial intermediate step in this wastewater treatment process is to fully aerate the wastewater to ensure the oxygen demand of the microorganisms, thereby achieving the function of fully degrading the organic matter in the wastewater.
[0003] A wastewater treatment aeration device with uniform aeration, disclosed in CN216472429U, connects to a hollow rotating shaft via an air pump's guide pipe. Gas enters the aeration component from the hollow rotating shaft, causing it to rotate laterally and slap against the wastewater. Simultaneously, the support rods are broken up to slap against the wastewater longitudinally. The device achieves slapping contact with the wastewater both laterally and longitudinally, while the numerous air outlets of the aeration component ensure full contact between the gas and the wastewater, significantly improving the uniformity of aeration and accelerating wastewater treatment efficiency.
[0004] The wastewater treatment uses aeration equipment with uniform aeration. The device uses a first filter screen and a second filter screen to filter the wastewater. However, the device cannot clean the first and second filter screens. When the filter screens are clogged, the resistance of the wastewater passing through the filter screens increases, the water flow speed slows down significantly, the amount of wastewater entering the aeration equipment for treatment through the filter screens decreases, and the overall wastewater treatment efficiency decreases. Therefore, improvements are needed. Utility Model Content

[0016] 1. This high-efficiency and energy-saving aeration equipment for sewage treatment can filter sewage through the filter plate in the lifting assembly. When the filter plate is clogged, the PLC controller turns on the drive motor, which drives the rotating plate and brush to rotate through the rotating shaft.

[0018] 2. This high-efficiency and energy-saving aeration equipment for sewage treatment uses a rotating motor in the aeration mechanism to drive the linkage rod and stirring plate to rotate. This not only allows the sewage to flow fully in the treatment tank, increasing the contact opportunity between the sewage and oxygen, but also promotes the uniform dispersion of the bubbles discharged from the aerator, thereby improving the oxygen mass transfer efficiency.

[0029] This utility model provides the following technical solution:
[0030] Example 1
[0031] Please see Figure 1-6 This utility model provides a technical solution: a high-efficiency and energy-saving aeration device for sewage treatment, including a fixed frame 1, a treatment box 5 fixedly connected to the top of the fixed frame 1, a lifting filter mechanism 2 provided inside the fixed frame 1, an outlet pipe 3 fixedly connected to the front of the treatment box 5, an electric butterfly valve 6 fixedly connected inside the outlet pipe 3, and an aeration mechanism 4 provided at the bottom inside the treatment box 5.

[0035] Furthermore, a sealing groove corresponding to the position of the sealing plate 212 is provided on the top of the processing box 5, and the sealing plate 212 is inserted into the sealing groove. Through the sealing groove, the sealing plate 212 can be inserted into the sealing groove to seal the top of the processing box 5.
[0036] Example 2
[0037] Please see Figure 1-6 Furthermore, based on Embodiment 1, the filter assembly 22 further includes a fixing plate 221, which is fixedly connected to the bottom of the sealing plate 212. A load-bearing plate 223 is fixedly connected to the bottom of the fixing plate 221. An insert plate 224 is inserted into the inner side of the load-bearing plate 223. A filter plate 225 is fixedly connected to the top of the insert plate 224. A bolt 222 is threadedly connected inside the filter plate 225.

[0039] Example 3
[0040] Please see Figure 1-6 Furthermore, based on Embodiment 1, the aeration mechanism 4 further includes a rotating motor 41, which is fixedly connected to the back end of the treatment box 5. A linkage rod 43 is fixedly connected to the front of the rotating motor 41. A stirring plate 42 is fixedly connected to the periphery of the linkage rod 43. A sealing ring 46 is rotatably connected to the front periphery of the linkage rod 43. The sealing ring 46 is fixedly connected to the front inner side of the treatment box 5. An air outlet pipe 45 is rotatably connected inside the linkage rod 43. An aerator 44 is fixedly connected to the front of the air outlet pipe 45. The aerator 44 is fixedly connected to the front of the treatment box 5.
[0041] Furthermore, exhaust ports are provided on the inner side of the linkage rod 43 and the inner side of the mixing plate 42. Through the exhaust ports, the aerator 44 can transmit gas into the treatment tank 5 for aeration treatment of sewage.
[0042] In actual operation, when this device is used, the filter plate 225 is placed on top of the load-bearing plate 223, and the filter plate 225 is installed on the inside of the linkage plate 211 by bolts 222. The cylinder 218 is opened by the PLC controller, so that the cylinder 218 drives the lifting plate 213 to move downward through the linkage plate 211. The lifting plate 213 drives the load-bearing plate 223 to move downward through the fixing plate 221, so that the load-bearing plate 223 drives the filter plate 225 into the treatment tank 5. The sewage to be treated is poured into the treatment tank 5, so that the sewage can be filtered through the filter plate 225. The filtered sewage enters the bottom of the treatment tank 5.
[0043] The PLC controller turns on the aerator 44, causing it to discharge gas through the outlet pipe 45 into the linkage rod 43. The PLC controller also turns on the rotary motor 41, causing it to drive the mixing plate 42 to rotate via the linkage rod 43. This allows the gas to be discharged through the exhaust holes inside the linkage rod 43 and the mixing plate 42, ensuring that the wastewater flows fully within the treatment tank 5. This increases the contact between the wastewater and oxygen, promotes the uniform dispersion of the bubbles discharged from the aerator 44, improves the oxygen mass transfer efficiency, and helps maintain the normal operation of various biological and chemical processes in the wastewater.
[0044] When the filter plate 225 becomes clogged, the PLC controller activates the drive motor 214, causing the drive motor 214 to rotate the rotating shaft 215 and the rotating plate 216. This allows the rotating plate 216 to rotate the brush bristles 219, enabling the brush bristles 219 to clean the top of the filter plate 225 and prevent clogging. When the filter plate 225 needs to be disassembled and cleaned after prolonged use, the PLC controller activates the cylinder 218, causing the cylinder 218 to move the adjusting plate 217 and the linkage plate 211 upwards, thus preventing the linkage plate from becoming clogged. 211 can move the fixed plate 221 and the load-bearing plate 223 upward through the lifting plate 213, so that the load-bearing plate 223 can move the filter plate 225 upward, so that the filter plate 225 is away from the inside of the treatment box 5. Rotate the bolt 222 so that the bolt 222 is away from the inside of the filter plate 225. The operator pulls the filter plate 225 upward, so that the filter plate 225 is away from the load-bearing plate 223, so that the filter plate 225 can be disassembled by the operator, so that the operator can clean the filter plate 225, so that the filter plate 225 can be reused after installation.
