And contain a large amount of flocs in industrial waste water, this flocs can block the filter device of waste water treatment equipment when waste water is filtered, and existing waste water treatment equipment generally all is to install filter screen on waste water treatment equipment, through The filter screen filters out the flocs in the wastewater. This operation method will cause the filter screen to be blocked during long-term filtration, which will reduce the treatment speed of the wastewater, and the long-term contact of the flocs with the wastewater will easily cause floating microorganisms to interact with the wastewater. The reaction makes the waste water have the possibility of re-pollution. Therefore, the filter screen needs to be replaced frequently. At present, the filter screens in the sewage treatment equipment on the market are basically replaced according to the working conditions, and the filter screens are replaced regularly by special personnel, and the equipment needs to be stopped during the replacement. When the wastewater contains more flocs, the filter screens The replacement will be very frequent, which will reduce the continuity of wastewater filtration, thereby reducing the efficiency of wastewater treatment.

At present, the publication date is February 07, 2020, and the Chinese invention patent with the publication number CN110759502A proposes a treatment device for industrial wastewater with floc components, which includes a sedimentation mechanism, a driving mechanism, a filtering mechanism, and a drainage mechanism , decontamination mechanism; the sedimentation mechanism includes a sedimentation tank and a water outlet bucket, and the driving mechanism is installed on the top of the sedimentation tank; the decontamination mechanism is installed in the sedimentation tank, and the driving mechanism is installed on the top of the sedimentation tank, The transmission connection of the sewage mechanism, the drainage mechanism is installed on the side wall of the sedimentation tank, and is located at the bottom of the filter mechanism. Wherein the filter mechanism includes a fixed frame, a movable tank, a filter plate, a baffle, a support frame, a connecting column, a fixed nut and a rotating shaft; the fixed frame is fixedly connected on the opposite side walls of the sedimentation tank, and the rotating shaft is installed between the fixed frame The surface of the rotating shaft is rotatably connected with a connecting column, and the connecting column and the rotating shaft are fixedly connected by fixing nuts. The surface of the connecting column is relatively equidistantly welded with a support frame, and a filter plate is slidingly connected between the longitudinal support frames. Adjacent filter plates The surface of the connecting column between them is welded with a baffle plate parallel to the rotating shaft to avoid splashing of waste water. The side wall of the sedimentation mechanism is provided with a movable groove for providing a rotating space for the support frame and the filter plate. The filter plate is located at the bottom of the outlet bucket. .

When the wastewater in the sedimentation tank is discharged from the outlet bucket, the wastewater flows directly to the surface of the filter plate, the flocs in the wastewater are filtered by the filter plate, and the wastewater after the flocs are filtered flows out from the bottom of the filter plate. When the plate needs to be replaced, turn the support frame clockwise to replace the next filter plate.

It may fall into the drainage mechanism, which may cause secondary pollution of the water in the drainage mechanism; in order to reduce the probability of secondary pollution of the water in the drainage mechanism, when the operator rotates the filter plate, it is necessary to stop the sedimentation tank first. For sewage discharge, when the filter plate is rotated in place, the sewage in the sedimentation tank will continue to be drained again. This operation will reduce the continuity of the filter plate’s work, thereby reducing the efficiency of wastewater treatment.

At this time, the water supply tank 422 feeds the spray head through the third water outlet 4222. 421 supplies water, and the spray head 421 sprays water to the filter screen 320 from the water outlet hole, and runs the second driving member 431 at the same time, and the second driving member 431 drives the gear 432 to rotate, and the gear 432 and the rack 433 are meshed and driven, so that the spray head 421 Move back and forth along the moving direction of the filter screen 320, by moving the shower head 421, the cleaning range of the filter screen 320 is increased, and the cleaning efficiency of the filter screen 320 is improved; at the same time, the shower head 421 drives the brush roller 441 to move, and the brush roller 441 Rotate on the surface of the filter screen 320, so that the flocs on the filter screen 320 are adsorbed on the brush roller 441, and the cleaning of the flocs on the filter screen 320 is completed; The cleaning speed of the filter screen 320 is also reduced, and the content of flocs mixed in the water after cleaning is also reduced; at the same time, the water flowing out of the water spray hole 4211 flows into the filter screen 320 through the fourth water inlet 4511 after cleaning the filter screen 320 In the spray water collection box 451, when the waste water in the spray water collection box 451 is more, run the first water pump 452, make the waste water in the spray box flow into the first water inlet 101 through the fourth water outlet 4512, and then Back to the reservoir 100; and when the amount of water in the water supply tank 422 decreases, run the second water pump 453, so that the water in the drainage tank 201 enters the third water inlet 4221 through the second water outlet 203, thereby flowing into the water supply Box 422. In this way, the cleaning water of the filter screen 320 can be recycled, which saves the water consumption of the filter screen 320 in the cleaning process, and at the same time reduces the environmental pollution caused by the discharge of waste water generated during the cleaning process.

The implementation principle of a kind of waste water treatment equipment that can handle flocs in the embodiment of the present invention is as follows:

When the waste water in the reservoir 100 needs to be filtered, the first driving member 333 is operated, and the first driving member 333 drives the first rotary shaft 331 to rotate, and the rotation of the first rotary shaft 331 drives the filter screen 320 to rotate, and the filter screen 320 drives the second rotary shaft 331 to rotate. The rotating shaft 332 and the supporting roller 341 rotate, and then the filter screen 320 is moved circularly between the first rotating shaft 331 and the second rotating shaft 332. When the filter screen 320 is in the circular operation process, the perimeter of the filter screen 320 becomes longer, and the lower side When there is an underlap, the up and down position of the adjusting plate 342 can be adjusted by adjusting the position of the mounting nut 344 on the adjusting bolt 343, and then the up and down position of the idler roller 341 can be adjusted so that the lower edge of the filter screen 320 is supported by the idler roller 341. The tension state is restored again, so the setting can reduce the probability of slipping of the filter screen 320 in the annular running process, so as to maintain the filtering effect of the filter screen 320. At the same time, waste water flows out through the first water outlet 102, and falls on the filter screen 320 from the U-shaped mouth position on the baffle plate 351, because a sealing brush 352 is arranged between the baffle plate 351 and the filter screen 320, at this time The sealing brush 352 can reduce the probability that unfiltered waste water enters the drainage tank 201; then the waste water continues to fall through the filter screen 320, and the flocs in the waste water stay on the filter screen 320 surface during the falling process, and the floc-free The waste water flows into the drainage pool 201 from the second water inlet 202 . Because the filter screen 320 always moves circularly during the filtering process, such setting indirectly increases the filtering area of the filter screen 320 and reduces the probability of the filter screen 320 clogging caused by the accumulation of flocs in the filter screen 320 per unit time. The filtering efficiency of the filter screen 320 is indirectly improved, thereby improving the wastewater treatment efficiency.

At the same time, when the filter screen 320 moves circularly, the flocs on the filter screen 320 will be moved to one end of the first rotating shaft 331 along with the movement of the filter screen 320. At this time, the water supply tank 422 is sprayed through the third water outlet 4222. The head 421 supplies water, and the spray head 421 sprays water on the filter screen 320 from the water outlet hole, and at the same time runs the second drive member 431, which drives the gear 432 to rotate, and the gear 432 and the rack 433 are meshed for transmission, so that the spray head 421 reciprocates along the moving direction of the filter screen 320, by moving the shower head 421, the cleaning range of the filter screen 320 is increased, and the cleaning efficiency of the filter screen 320 is improved; at the same time, the shower head 421 drives the brush roller 441 to move, and the brush roller 441 rotates on the surface of the filter screen 320, so that the flocs on the filter screen 320 are adsorbed on the brush roller 441, and the cleaning of the flocs on the filter screen 320 is completed; The cleaning speed of the filter screen 320 is also reduced, and the content of flocs mixed in the water after cleaning is also reduced; at the same time, the water flowing out of the water spray hole 4211 passes through the fourth water inlet 4511 after cleaning the filter screen 320 Flow into the spray water collection box 451, when the waste water in the spray water collection box 451 is more, run the first water pump 452, make the waste water in the spray box flow into the first water inlet 101 through the fourth water outlet 4512, And then back to the water storage tank 100; and when the water volume in the water supply tank 422 decreases, run the second water pump 453, so that the water in the drainage tank 201 enters the third water inlet 4221 through the second water outlet 203, thereby flowing into In the water supply tank 422. In this way, the cleaning water of the filter screen 320 can be recycled, which saves the water consumption of the filter screen 320 in the cleaning process, and at the same time reduces the environmental pollution caused by the discharge of waste water generated during the cleaning process.

The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention, so: all equivalent changes made according to the structure, shape and principle of the present invention should be covered by the protection scope of the present invention Inside.
