A rainwater collection filter

Abstract

The invention provides a rainwater collection filter. The rainwater collection filter comprises a collection device (1), a first filtering device (2), a settling device (3), a first air cylinder device (4), a second filtering device (5), a second air cylinder device (6) and a third filtering device (7), wherein the collection device (1) comprises a collection frame (11), a first filter screen (12) and a first spring (13); the first filtering device (2) comprises a first frame body (21), a second filter screen (22), a sponge rod (23), a second spring (24) and a first centralizing block (25); the settling device (3) comprises a settling frame (31), a first bracket (32), a third spring (33), a third filter screen (34) and a fourth spring (35); and the first air cylinder device (4) comprises a first air cylinder (41), a first push rod (42) and a first push plate. The rainwater collection filter has relatively good filtering effect and relative high efficiency and can be used for collecting and filtering rainwater, so that water resources are saved.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and purification treatment, in particular to a rainwater collection filter. Background technique [0002] China is a country suffering from severe drought and water shortage. The total water shortage in the country reaches 400 billion cubic meters, while the average annual total rainwater resources in my country exceed 6 trillion cubic meters. Rainwater is a very high-quality fresh water resource in nature and is a part of life. In recent years, domestic cities have been continuously affected by heavy rains, causing urban waterlogging. At the same time, in the north and some other cities, land subsidence has occurred due to excessive exploitation of groundwater. The emergence of these situations is directly or indirectly related to rainwater. At present, in terms of comprehensive utilization of rainwater, the water storage device adopts a water storage tank. The storage tank is a co...

Problems solved by technology

However, it does not have a special rainwater collection device and needs to be used in conjunction with other rainwater collection equipment, which is limited in use; and it cannot precipitate rainwater, and cannot effectively remove impurities in rainwater; at the same time, it cannot control the speed of rainwater filtration and cannot Adjust the flow rate of rainwater filtration according to the needs; and it is impossible to pre-filter the impurities with large particle sizes in the sewage, so that the impurities with large particle sizes can easily block the filter screen, making the sewage filtration impossible.
