Description

Wastewater treatment device

Technical Field

The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device.

Background Art

According to a corporate wastewater treatment device provided by Chinese patent document CN218262005U, it includes a treatment box, a fixed base, an inlet pipe and an outlet pipe, wherein a first filter screen and a second filter screen are fixedly installed inside the treatment box, and scrapers are rotatably connected to the surfaces of the first filter screen and the second filter screen, and a transmission pipe is fixedly installed on the upper surface of the treatment box and located between the first filter screen and the second filter screen, and a turntable is rotatably connected to the inner bottom of the transmission pipe, and a longitudinal stirring shaft is rotatably connected to the interior of the treatment box and located between the first filter screen and the second filter screen. In the corporate wastewater treatment device described in the utility model, two scrapers rotate on the surfaces of the first filter screen and the second filter screen respectively to clean the particles on the surfaces of the first filter screen and the second filter screen, thereby avoiding the clogging of the first filter screen and the second filter screen by the particles and accelerating the efficiency of treatment, and at the same time, the particles enter the waste residue storage box through the transmission pipe.

However, there are still some shortcomings in the actual use of the wastewater treatment device. For example, after the particles on the No. 1 filter and the No. 2 filter are scraped off by the scraper, the scraped particles will still be suspended in the wastewater, and then re-attach to the filter under the flow of wastewater. At the same time, the particles suspended in the wastewater will not enter the waste residue storage box on the lower side. In addition, the disinfectant can be added in one time after the dosage is calculated, without the need to use other structures for uniform addition, which increases the cost. When adding it to the wastewater to make it mix evenly, the water flow needs to surge, and the mixing effect achieved by only two sets of smaller stirring shafts is poor. For this reason, we propose a wastewater treatment device to solve the above problems.

The reduction motor 16 is started to drive the shaft 15 to rotate, and the rotation of the shaft 15 drives the stirring rod 17 to rotate, and the rotation of the stirring rod 17 drives the flow plate 18 to rotate. The larger area of the flow plate 18 can effectively drive a large amount of wastewater to turn over when rotating to achieve the purpose of stirring and mixing. Further, the resistance of the wastewater to the flow plate 18 can be greatly reduced through the through hole 19. At the same time, the through hole 19 can improve the stirring effect and speed up the mixing efficiency. Due to the limiting effect of the coarse filter 2 and the fine filter 3 on the scraper box 9, the screw rod 4 can be rotated to make The threaded sleeve 10 drives the scraper box 9 to move up and down, so that the particles attached to the coarse filter 2 and the fine filter 3 can be scraped off and confined inside the scraper box 9 by descending. When the scraper box 9 descends to the filter plate 12 in the collection box 11, it stops. The particles can be blocked by the filter plate 12, and then the wastewater under the filter plate 12 in the collection box 11 is pumped out and re-discharged into the next treatment mechanism in the filter box 1 by starting the water pump 14, thereby avoiding the coarse filter 2 and the fine filter 3 being blocked by particles, thereby accelerating the treatment efficiency.

Further, the resistance of the wastewater to the flow plate 18 can be greatly reduced through the through hole 19. At the same time, the stirring effect can be improved through the through hole 19, and the mixing efficiency can be accelerated. The main pulley 7 is driven to rotate by starting the driving motor 6, and the transmission belt 8 is driven by the main pulley 7 to make the slave pulley 5 rotate synchronously, and the screw rod 4 is driven by the slave pulley 5. The filter screen 2 and the fine filter screen 3 have a limiting effect on the scraper box 9. The rotation of the screw rod 4 can make the threaded sleeve 10 drive the scraper box 9 to move up and down, so that the particles attached to the coarse filter screen 2 and the fine filter screen 3 can be scraped and confined inside the scraper box 9 when it descends. When the scraper box 9 descends to the filter plate 12 in the collection box 11, it stops. The particles can be blocked by the filter plate 12, and then the wastewater under the filter plate 12 in the collection box 11 is pumped out and re-discharged into the next treatment mechanism in the filter box 1 by starting the water pump 14, thereby avoiding the coarse filter screen 2 and the fine filter screen 3 being blocked by particles, thereby accelerating the treatment efficiency.
