Rainwater filtering device

Abstract

The invention relates to a rainwater filtering device, and belongs to the technical field of filtering equipment. The blade I, the spiral guide plate and the blade III are connected through the rotating shaft, water flow is pressurized through the water collecting hopper, the flow speed is increased, the blade I is impacted, the water flow is filtered, subjected to reducing pressurization through the annular guide plate and impacted on the blade III, the rotating shaft is driven by the blade I and the blade III to rotate, and the spiral guide plate is driven by the rotating shaft to rotate. Therefore, rotating water flow is formed in the filter cartridge, impact of the water flow on the wall of the filter cartridge is improved, the filtering effect of the filter cartridge is effectively improved, meanwhile, when the filter cartridge passes through the spiral guide plate, the water flow can drive the filter cartridge to rotate through the spiral guide plate, and it is guaranteed that the spiral guide plate can rotate when the water flow is small. In addition, in the rotating process of the spiral guide plate, sundries attached to the inner wall of the filter cartridge can be scraped up, so that the sundries can flow downwards to flow into the bottom of the filter cartridge, and the filtering capacity of the filter cartridge is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of filtering equipment, and in particular relates to a rainwater filtering device. Background technique [0002] With the development of society, in order to solve the problems of water shortage, environment and ecology, people pay more and more attention to the collection and utilization of rainwater. Rainwater collection has brought many life benefits. The collected rainwater is used for laundry, Wash the car or water it, etc. The collection and utilization of rainwater can also reduce the amount of rainwater runoff in urban streets, reduce the pressure of urban drainage, and at the same time effectively reduce the confluence of rainwater and sewage, and reduce the pressure of sewage treatment. However, nowadays, rainwater collection in special environments such as high slopes, rocky slopes, desert Gobi areas or areas with poor air quality and severe dust has problems of difficult collection and secondary...

Problems solved by technology

However, nowadays, rainwater collection in special environments such as high slopes, rocky slopes, desert Gobi areas, or areas with poor air quality and severe sand and dust has the problem of difficult collection and secondary application. Rainwater is easy to mix with impurities in the surrounding environment through contact. , resulting in the presence of impurities such as sediment particles in the collected rainwater, the application of sedimentation is time-consuming and laborious, and the impact of secondary evaporation also needs to be considered. The use of ordinary mesh filters requires manual follow-up cleaning of the plug, causing great inconvenience

[0003] Rainwater filtration is an important part of rainwater collection. Nowadays, most of the rainwater filtration is screen filtration, followed by sedimentation filtration. The filtration efficiency is average, and the filtration method requires a large investment. It is necessary to create a suitable filtration environment and space, which cannot be combined The real pipeline is used for filtering, which is not very practical
