Abstract
The utility model discloses a rainwater primary filtering device which comprises a case and a top cover plate. The case and the top cover plate are made of polypropylene plastic plates, a water inlet is formed in one side of the case, a water outlet is formed in the other side of the case, a vertical exhaust valve and a ball valve are arranged on the top cover plate, a filter screen and an accumulating hopper are arranged in the case, and the accumulating hopper is positioned below the filter screen. The rainwater primary filtering device has the advantages that the case and the top cover plate are selectively made of the polypropylene plastic plates, the filter screen and the accumulating hopper are arranged in the case, accordingly, suspended matters and particulate matters can be effectively filtered in a rainwater collecting procedure, and the rainwater primary filtering device is simple in structure and easy to install and maintain.
Description
Technical field
The utility model relates to a kind of rainwater-collecting treating apparatus, relates in particular to a kind of rainwater initial filter device.
Background technology
Water is the most valuable resources of the mankind, but due to the mankind's waste and the pollution of environment, cause clean water resource day by day to reduce, along with society and economic developing rapidly, the city process is accelerated, water resource worsens, groundwater table descends, the water difficult problem in city is also day by day serious, in 600 cities of China, 300 lacks of water are arranged, having more than 100 of serious water shortage is individual, and just in rising trend, for this reason, country spends huge sums and carries out project of South-to-North water diversion, yet can only meet the problem of water consumption of some areas, can not fundamentally solve the problem of lack of water, urbanization makes original vegetation and soil be replaced by waterproof ground in addition, a large amount of rainwater run off, the broken natural, ecological hydrological environment of having changed, underground water can not get effectively supplementing, reduce year by year, the deterioration of the ecological environment in city, in soil, water content reduces, the heat island effect aggravation, the air drying, during rainfall, because the urbanization infiltration of rainwater is not strong, rainwater accelerates to collect to the river course in city, peak flood flow is built rapid formation, the load of urban sewerage and drainage facility strengthens, waterlogging disaster takes place frequently, rainwater is as a kind of clean water source, comprehensive utilization of resources and control, in environment and water resource utilization, the control aspect plays and must act on, to our human settlement, water conservancy ecosystem has profound significance.
At present, increasing country starts to note collecting clean rainwater, rainwater collects common employing roof, ground level road, greenery patches, natural hillside etc., early-stage rainwater is after cutting dirt, the a large amount of suspensions that are mingled with (branch, leaf, foam, plastic sheeting, paper scrap etc.) particle (garrulous bricks and stones, silt particle soil etc.) major part has been cut dirty the filtration, but remain the not diffluent objects such as the suspension of (particle diameter≤3mm) and particle in rainwater, therefore, early-stage rainwater is collected after filtration treatment again, rainwater is further filtered, and the system of assurance security of operation.Traditional early-stage rainwater filter method filter well, drawback is that civilwork engineering quantity is large, invests highly, labour intensity is large.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rainwater initial filter device, suspension and particle in the rainwater-collecting process of can effectively coming, and simple in structure, be easy to installation and maintenance.
The utility model is to solve the problems of the technologies described above the technical scheme adopted to be to provide a kind of rainwater initial filter device, comprise casing and lamina tecti, the material of described casing and lamina tecti is the polypropylene plastics flitch, one side of described casing is provided with water inlet, opposite side is provided with delivery port, described lamina tecti is provided with vertical outlet valve and ball valve, is provided with screen pack and hopper in described casing, and described hopper is positioned at the below of screen pack.
Above-mentioned rainwater initial filter device, wherein, described screen pack is three layers of stainless steel plate mesh, the order number of described three layers of stainless steel plate mesh is respectively 60 orders, 40 orders and 20 orders from top to bottom.
Above-mentioned rainwater initial filter device, wherein, described lamina tecti comprises the two layers of polypropylene plastic plate, between described two layers of polypropylene plastic plate, is provided with rubber sheet gasket.
