分析了传统一体化净水器斜管易堵塞弊端和反冲洗缺陷,并进行了相应的改进研究。首先,将一体化净水器的沉淀装置改为下层小间距斜板加上层斜管的双层沉淀装置,它能有效增加沉淀面积,克服下层斜管频繁堵塞的问题;其次,在无阀滤池的虹吸破坏管顶端及进水管末端分别设置放气阀及进水控制阀,通过出水浊度及虹吸下降管中水流流量分别控制两个阀门的启闭,既能避免由于积气等问题导致的频繁冲洗,又能解决反冲洗时进水不间断,水源浪费问题,实现反冲洗自动识别;此外,在无阀滤池反冲洗出水管管口加设可旋转式阻砂及砂水分离器,有效避免反冲洗时滤料流失。新型一体化净水器比传统净水器体积更小,智能化程度更高,在相同处理能力下,反冲洗水量及滤料流失更少,制水成本更低。
The defects of easy plugging and backwash of the traditional integrated water purifier oblique pipe were analyzed and corresponding improvement research was carried out. First of all, the integrated water purifier settling device was changed to the lower small-pitch inclined plate plus inclined pipe double-layer sedimentation device, which can effectively increase the precipitation area, to overcome the lower inclined pipe frequent plugging problems; Second, Pool siphon damage pipe top and inlet pipe ends were set deflation valve and inlet control valve, through the water turbidity and siphon drop in the water flow control flow of two valves were opened and closed, both to avoid problems due to gas accumulation Of the flushing, but also solve the uninterrupted backwash water, waste water problems, to achieve automatic identification of backwash; In addition, no valve filter backwash outlet pipe nozzle can be added rotary sand and sand separator , Effectively prevent backwash filter loss. The new integrated water purifier smaller than the traditional water purifier, a higher degree of intelligence, the same processing power, backwash water and less media loss, lower water costs.
