Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, to sewage treatment and purification equipment for drainage engineering. Background Art

[0002] The sewage flocculation treatment and purification equipment of the drainage project plays an important role in the sewage treatment process. Its main use is that the sewage flocculation treatment equipment can effectively remove suspended matter, colloidal particles, organic matter, inorganic matter and other pollutants in the sewage through flocculation. If these substances are discharged directly into the environment without treatment, they will cause serious damage to the water body, soil and ecosystem. After flocculation treatment, these pollutants will gather into larger clusters, which are convenient for subsequent precipitation or filtration, thereby achieving the purpose of purifying the water body.

[0003] In the existing public documents, the patent announcement number CN219730643U discloses a sewage treatment device with good purification effect. The treatment device is fixedly connected with a water suction pump above the cylindrical net slot seat through the lower opening cylindrical tube, and the surface of the cylindrical net slot seat is fixedly connected with a sealing plate. The water suction pump, the lower opening cylindrical tube and the drainage pipe can fully promote the circulation of water in the equipment, and the solid medicine for treating sewage can be fully contacted during the water circulation, which greatly improves the purification effect of sewage and is more suitable for the treatment of large amounts of sewage in water conservancy projects. However, this technology still has the following defects.

[0004] When sewage treatment and purification equipment is in use, flocculants need to be added to mix with sewage, thereby producing a large amount of impurity precipitation. During the precipitation process, the sewage needs to be filtered and treated, and the purified sewage is discharged, which will leave a large amount of impurities. The impurities are very easy to clog, and it is inconvenient to clean the impurities inside. The flocculation treatment and purification efficiency is greatly reduced. Therefore, a sewage treatment and purification equipment for drainage projects is needed. Summary of the invention

Finally, the impurities adsorbed on the outer wall of the rotating shaft are discharged to the upper surface of the filter plate, and the impurities are discharged along the inside of the purification tank. In summary, the flocculated impurities are not easy to be blocked, and the flocculated impurities are quickly discharged. In this way, the internal flocculated impurities are more convenient to handle, which greatly improves the flocculation treatment and purification efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The working principle of the sewage treatment and purification equipment of the drainage project of the present invention is as follows: Step 1, during sewage treatment and purification, the sewage from the drainage project is poured into the purification tank 1, and the flocculant is inserted into the purification tank 1, so that by starting the position shifting motor 5, the position shifting motor 5 drives the sensing end of the angle sensor 4 to rotate forward 90 degrees and then reverse 90 degrees, the sensing end of the angle sensor 4 drives the rotating shaft 3 to rotate forward 90 degrees and then reverse 90 degrees, the rotating shaft 3 drives the filter plate 6 to rotate forward 90 degrees and then reverse 90 degrees, and the rotating shaft 3 drives the sleeve rotating block 20 to rotate forward 90 degrees and then reverse 90 degrees, the sleeve rotating block 20 drives the slide block 23 to rotate forward 90 degrees and then reverse 90 degrees, the lower discharge pipe 30 drives the guide bar 13 to rotate forward 90 degrees and then reverse 90 degrees, the guide bar 13 drives the lower discharge ring 14 to rotate forward 90 degrees and then reverse 90 degrees, the lower discharge ring 14 drives the linkage guide ring 15 to rotate forward 90 degrees and then reverse 90 degrees, and the rotating shaft 3 drives the filter plate 6 to rotate forward 90 degrees and then reverse 90 degrees.

[0034] At the same time, the sleeve rotating block 20 drives the linkage rod 21 to rotate forward 90 degrees and then reverse 90 degrees, the linkage rod 21 drives the mixing blade 22 to rotate forward 90 degrees and then reverse 90 degrees, the slide block 23 drives the guide bar 13 to rotate forward 90 degrees and then reverse 90 degrees, the guide bar 13 drives the sliding column 12 to rotate forward 90 degrees and then reverse 90 degrees, the sliding column 12 rotates forward 90 degrees along the inside of the groove ring 11 and then reverses 90 degrees, so as to realize the flocculation sewage treatment operation for the water inside the purification tank 1.

[0035] Step 2: When the water flows downward, the output pump 34 is started by the controller 18, and the mounting frame 17 supports the controller 18, so that the output pump 34 can make the water inside the purification tank 1 be discharged into the discharge pipe 31, and poured into the guide pipe 32 through the discharge pipe 31, and the discharge valve 33 is opened by the controller 18, so that the water is poured into the discharge valve 33, and poured into the output pump 34 through the discharge valve 33, so that the output pump 34 can discharge the purified water.

[0036] When the water inside the purification tank 1 is completely discharged, the electric valve 29 is opened by the controller 18. By opening the electric valve 29, the purification tank 1 is connected with the discharge pipe 28. At the same time, the discharge pipe 28 is connected with the electric valve 29, and the electric valve 29 is connected with the discharge pipe 30.

[0037] Step three, when diverting downward, the support block 27 is provided with supporting force through the rotating shaft 3, the support block 27 supports the electric cylinder 24, the controller 18 starts the electric cylinder 24, the electric cylinder 24 pushes the impact sleeve 25 to move downward, the impact sleeve 25 drives the impact pad 26 to move downward, the impact sleeve 25 moves downward along the inner wall of the rotating shaft 3, and at the same time, the impact sleeve 25 drives the impact pad 26 to move downward, so that the impurities adsorbed on the outer wall of the rotating shaft 3 are discharged to the upper surface of the filter plate 6.

[0038] Step 4: During flocculation and diversion treatment, the controller 18 is used to start the rotating motor 9, which drives the screw 8 to rotate. The screw 8 rotates inside the groove column 7, and the screw 8 drives the threaded sleeve 10 to move downward under the action of the thread transmission force.

In this way, the upper surface of the linkage guide ring 15 is located below the filter plate 6, so that the rotating motor 9 is turned off by the controller 18.

[0039] The controller 18 is used to start the position shifting motor 5, which drives the sensing end of the angle sensor 4 to rotate forward 90 degrees and then reverse 90 degrees. The sensing end of the angle sensor 4 drives the rotating shaft 3 to rotate forward 90 degrees and then reverse 90 degrees. The rotating shaft 3 drives the filter plate 6 to rotate forward 90 degrees and then reverse 90 degrees. In this way, the impurities on the upper surface of the filter plate 6 can rotate back and forth, so that the impurities can rotate into the inner wall of the purification tank 1, and the impurities flow down along the gap between the purification tank 1 and the filter plate 6. The impurities flow down along the top of the linkage guide ring 15, so that the impurities are discharged into the discharge pipe 28 along the inside of the purification tank 1, and the impurities are poured into the lower discharge pipe 30 along the electric valve 29, and the lower discharge pipe 30 performs the lower discharge operation. In this way, the flocculant impurities can be quickly discharged, and the lower discharge efficiency is greatly improved.
