[0002] In the field of house building construction, wastewater treatment device as the key equipment of environmental protection construction, its filtering efficiency, cleaning convenience and structural stability directly affect the environmental protection effect and operation and maintenance cost of construction site, however, current wastewater treatment device on the market still has many technical defects in practical application, these problems not only affect equipment performance, also can cause environmental pollution.
[0003] The primary problem is that the filtering efficiency decays seriously, the wastewater treatment device in the prior art has significant defects: first, a large amount of impurities and foreign matters are easily accumulated on the surface of the filter plate, affecting the filtering effect; second, the accumulation of sediments can cause the blockage of the filtering channel, reducing the processing efficiency; third, the scaling phenomenon on the surface of the filter plate is serious after long-term use, affecting the equipment performance, and the delay in cleaning of the filter plate not only reduces the wastewater treatment efficiency, but also can cause equipment damage due to blockage, which not only affects the actual effect of wastewater treatment, but also can cause environmental pollution due to insufficient filtration, increasing the environmental protection risk of the construction site.
[0004] More prominent is the inconvenience of cleaning mechanism, although some improved equipment adopts the cleaning method of stirring plate combined with brush, there are obvious problems: first, the brush is prone to wear and deformation after long-term use, and the replacement process of the brush is complex and time-consuming; second, professional tools are needed to assist in the disassembly and assembly process, and the cumbersome maintenance procedure not only increases the workload, but also can cause damage to the parts due to improper operation, which not only reduces the maintenance efficiency of the equipment, but also can cause the filtering effect to decrease due to the delay in cleaning, increasing the operation and maintenance cost and workload.
[0005] The most critical is the lack of structural stability, although some equipment realizes the quick disassembly and assembly function of the brush, there are serious problems: first, the connection structure is designed simply, and the vibration during equipment operation can cause the fastener to loosen, and the high-speed rotation of the stirring plate can generate centrifugal force, affecting the connection stability, and the loosening of the structure not only affects the cleaning effect, but also can cause the brush to fall off, causing equipment damage, which not only affects the reliability of the equipment, but also can cause secondary pollution due to structural failure, increasing the environmental risk of the construction site.
