Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment equipment, and in particular to a micro-arc oxidation sewage treatment device. Background Art

[0002] Micro-arc oxidation, also known as plasma electrolytic oxidation, is developed from the anodic oxidation technology, and the coating formed is superior to anodic oxidation. Micro-arc oxidation products will produce a lot of wastewater during production and cleaning of micro-arc oxidation products after production. Most of these wastewaters contain a lot of pollutants, so they need to be treated before discharge.

[0003] In the process of micro-arc oxidation wastewater treatment in most manufacturers, the wastewater is usually discharged into a tank, and chemicals are added into the wastewater to precipitate the pollutants and impurities in the wastewater, and then the precipitates are collected uniformly. In the process of mixing the sewage and the chemicals, in order to make the chemicals and sewage mix quickly, a motor-controlled stirring rod is usually used to stir the sewage. However, during the stirring process, the sewage around the stirring rod flows faster, and the liquid flow rate near the corner of the tank is slower, which is not convenient for rapid mixing of the sewage and the chemicals in the tank. At the same time, the slow liquid flow rate in the corner of the tank can easily cause the sediment in the sewage to settle, and when the sewage and sediment are transferred out of the mixing tank, there is a lot of sediment residue.

After the sewage and the liquid medicine are mixed, the first conveying component 3 conveys the mixed liquid to the static tank 13, and the mixed liquid is statically precipitated in the static tank 13. After the precipitation is completed, the liquid on the upper layer of the precipitate is conveyed to the liquid storage tank 14 by the second conveying component 4, and the displacement component 5 transports the precipitate out of the static tank 13 and continues the next round of static separation of the mixed liquid, thereby facilitating the rapid treatment of sewage and helping to improve the efficiency of the micro-arc oxidation sewage treatment device during use.

[0034] Reference Figure 2 and Figure 3 The stirring device 2 is divided into three parts: a main stirring component 21, a first auxiliary stirring component 22 and a second auxiliary stirring component 23. The main stirring component 21 includes a first stirring disk 211, which is arranged close to the inner bottom wall of the chassis 1. A first motor 212 for controlling the rotation of the first stirring disk 211 is fixedly installed on the chassis 1. The first motor 212 is arranged on the outer bottom wall of the chassis 1. A first paddle 213 for paddle liquid is fixedly installed on the vertical side wall of the first stirring disk 211. A connecting rod 214 is fixedly installed on the first stirring disk 211. A second stirring disk 215 is fixedly installed on one end of the connecting rod 214 away from the first stirring disk 211. The second stirring disk 215 is coaxially arranged with the first stirring disk 211, and a second paddle 216 is fixedly installed on the vertical side wall of the second stirring disk 215.

[0035] Reference Figure 3 and Figure 4 Two arc-shaped rod segments 2141 are arranged on the connecting rod 214, and a straight rod segment 2142 is hingedly arranged in the middle of the arc of each arc-shaped rod segment 2141. The first auxiliary stirring component 22 includes a pull rod 221, and the end of the pull rod 221 close to the connecting rod 214 is hinged to the straight rod segment 2142. Mounting blocks 222 are fixedly installed on both sides of the connecting rod 214 on the chassis 1, and a T-shaped slide groove 223 is opened on the mounting block 222.

The end of the pull rod 221 away from the connecting rod 214 is hinged to the first slider 224, and a movable plate 225 is fixedly installed on the end of the first slider 224 away from the connecting rod 214, and a first stirring rod 226 is fixedly installed on the movable plate 225.

[0036] When medicine and sewage are put into the mixing tank 12, the first motor 212 controls the first stirring plate 211 to rotate to stir the liquid at the bottom of the mixing tank 12. The first stirring plate 211 drives the second stirring plate 215 to rotate through the connecting rod 214 to stir the liquid in the middle position of the mixing tank 12, and the first paddle plate 213 and the second paddle plate 216 are used to paddle the liquid to enhance the flow of the liquid, so as to facilitate the rapid mixing of sewage and medicine and accelerate the mixing effect. When the arc rod segment 2141 connected to the pull rod 221 rotates in the direction close to the mounting block 222, the pull rod 221 pushes the first slider 224 to slide on the mounting block 222 in the direction away from the first stirring plate 211. When the arc rod segment 2141 connected to the pull rod 221 rotates in the direction away from the mounting block 222, the pull rod 221 will pull the first slider 224 on the mounting block 222 to slide in the direction close to the first stirring plate 211. Therefore, when the first stirring plate 211 rotates to stir the liquid, the connecting rod 214 will pull the pull rod 221 to move so that the first slider 224 slides back and forth on the mounting block 222. The first slider 224 will drive the movable plate 225 and the first stirring rod 226 to slide back and forth to stir the liquid on both sides of the first stirring plate 211, which is beneficial to enhance the mixing effect of the liquid and accelerate the mixing speed of sewage and liquid medicine.

When the second slider 234 slides, it will drive the rack 235 to push the gear 237 to rotate, and the gear 237 will drive the turntable 238 to rotate synchronously. The second stirring rod 239 on the turntable 238 will make a circular motion to stir the liquid in the corner of the mixing pool 12, thereby enhancing the fluidity of the liquid in the corner of the mixing pool 12, preventing the liquid in the corner of the mixing pool 12 from accumulating and precipitating due to the slow flow rate, and also improving the mixing effect of the liquid in the corner of the mixing pool 12, so that the liquid in various parts of the mixing pool 12 can be quickly mixed.
