Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to continuous purification equipment for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily life of ordinary people. According to the nature of sewage, water pollution can be divided into two categories: one is natural pollution; the other is man-made pollution. Currently, man-made pollution is the greatest threat to water bodies. Water pollution can be mainly divided into three categories according to the different pollutants: chemical pollution, physical pollution and biological pollution. There are many ways to treat sewage, which can generally be summarized as physical, chemical and biological methods.

[0003] The invention patent with the patent number CN116553651A discloses an assembled sewage treatment tower capable of continuous filtration, including a treatment cylinder and a support frame, wherein the treatment cylinder is arranged inside the support frame and fixedly connected to the inner wall of the support frame, and also includes a coarse filtration device, which is arranged inside the treatment cylinder and slidably connected to the inner wall of the treatment cylinder, and the coarse filtration device is used to perform a coarse filtration operation on the sewage entering the treatment cylinder; an adsorption device, which is arranged in the part of the treatment cylinder below the coarse filtration device, and the adsorption device is slidably connected to the inner wall of the treatment cylinder, and the adsorption device is used to perform an adsorption operation on the sewage filtered by the coarse filtration device; and a fine filtration device, which is arranged in the part of the treatment cylinder below the adsorption device. The invention relates to the technical field of sewage treatment. The assembled sewage treatment tower capable of continuous filtration can freely delete or add devices according to the needs of use, and is convenient for free adjustment according to the characteristics of the sewage.

[0004] The above-mentioned device can be freely adjusted according to the characteristics of the sewage by freely deleting or adding devices. However, in the prior art, it is necessary to add an appropriate amount of coagulant according to the content of sludge impurities in the sewage, and accelerate the mixing by stirring. However, stirring and adding coagulants can only accelerate sedimentation, or sewage treatment is performed by filtration, but the filter screen may still be clogged. Therefore, no matter what method is used to treat the sewage, the actual sewage filtration still has a certain sedimentation reaction time or the time for cleaning the filter screen, and continuous treatment cannot be achieved, resulting in poor sewage treatment efficiency.

The second bevel gear 411 is driven to rotate synchronously by the rotation of the connecting shaft 412; it is realized that an appropriate amount of flocculant needs to be added according to the sewage with different impurity contents, so that the clogging time of the filter mechanism 5 is adaptively judged according to the amount of flocculant added, thereby adjusting the frequency of backwashing of the filter mechanism 5, without manual adjustment, simple operation, convenient and fast, and strong adaptability.

[0029] Specifically, the resistance assembly includes two triangular blocks 43, two resistance rods 44, two rotating shafts 414, two rotating blocks 415, two torsion springs 416 and four fixed plates 417.

[0032] Specifically, a plurality of turnover grooves 151 are provided in the hollow ring 15. The cooperation between the turnover plate 73 and the turnover grooves 151 ensures that the first filter plate 51 will not rotate when working normally.

In addition, through the setting of the one-way plate 611, only the suction holes 67 can take in air during suction, which ensures the suction force while preventing the impurities in the annular cavity 612 from being re-sucked into the protective shell 63, avoiding the backflow of impurities and ensuring its cleaning effect.

[0034] Working principle: First, the output shaft of the stirring motor 3 rotates to drive the stirring wheel 14 to rotate, then sewage is added from the first feed port 9, and flocculant is added from the second feed port 8, and the flow rate of the coagulant at the second feed port 8 is adjusted by moving the baffle 41, and then the rotating block 415 is driven to rotate under the action of the torsion spring 416, and the rotation of the rotating block 415 drives the resistance rod 44 to rotate, and the resistance rod 44 drives the triangular block 43 at the end to resist the side wall of the sealing plate 42 to avoid shaking and causing flow changes, and synchronously drives the L-shaped telescopic plate 45 to move, and the movement of the L-shaped telescopic plate 45 drives the limit column 46 to move along the inclined groove 47, and the synchronous movement of the L-shaped telescopic plate 45 drives the speed regulating motor 49 and the first bevel gear 410 to move along the inclined groove 47 , so that the meshing position of the first bevel gear 410 and the second bevel gear 411 changes, thereby adjusting the transmission speed thereof, and then the first bevel gear 410 is driven to rotate by the output shaft of the speed regulating motor 49, the first bevel gear 410 is driven to rotate by the rotation of the first bevel gear 410, the second bevel gear 411 is driven to rotate by the rotation of the second bevel gear 411, the connecting shaft 412 is driven to rotate synchronously by the rotation of the connecting shaft 412, the gear ring 57 is driven to rotate by the rotation of the gear ring 57, the rotating ring 53 above is driven to rotate by the rotation of the gear ring 57, the rotating ring 53 drives another rotating ring 53 to rotate synchronously through the connecting rod 12, the rotating ring 53 rotates to drive the flip shaft 58 to revolve, the revolving of the flip shaft 58 drives the third bevel gear 59 to revolve synchronously, and the third bevel gear 59 rotates to the position where it meshes with the arc rack 510 The third bevel gear 59 is driven to rotate, and the rotation of the third bevel gear 59 drives the flip shaft 58 to rotate. The rotation of the flip shaft 58 drives the first filter plate 51 to rotate 180 degrees. Then, the back of the first filter plate 51 is backwashed by sewage, and the filtered water is recycled through the drain port 11. Then, the third bevel gear 59 drives the first transmission shaft 72 and the first rotating wheel to rotate. The rotation of the first transmission wheel 71 drives the transmission belt 75 to drive the second transmission wheel 76 to rotate. The rotation of the second transmission wheel 76 drives the second transmission shaft 74 to rotate. The rotation of the second transmission shaft 74 drives the symmetrical reciprocating screw rod 64 to rotate. The rotation of the symmetrical reciprocating screw rod 64 drives the two push plates 65 to reciprocate. The push plates 65 move The U-shaped telescopic plate 62 is driven to move. As the U-shaped telescopic plate 62 moves, the vacant part between the U-shaped telescopic plate 62 and the push plate 65 is aligned with the suction hole 67 in turn, thereby ensuring that there is always at least one suction hole 67 for sucking impurities. Due to the setting of the one-way turntable 66, the sucked impurities are prevented from falling back onto the second filter plate 52. The push plate 65 moves in the opposite direction, driving the push plate 65 on the other side to suck the impurities blocked on the second filter plate 52 into the U-shaped telescopic plate 62. The original push plate 65 pushes the previously sucked impurities from the first discharge port 61 into the rotating ring 53. As the impurities in the rotating ring 53 accumulate, the impurities are squeezed into the annular cavity 612 and the storage box 610, and are finally discharged from the one-way plate 611.
