The filter plate 303 and the filter cartridge 304 are both composed of a fixing frame 305, a folding filter cotton 306 and a filter screen 307;
folding filter pulp 306 is fixed through fixed frame 305, and folding filter pulp 306 both sides all are provided with filter screen 307 for filter large granule impurity, fixed frame 305 is the rubber material, makes whole filter 303 and cartridge filter 304 have certain deformation space.
The cross section of cartridge filter 304 is oval, the vertical setting of oval-shaped major axis, the purpose is in order to alleviate the impact of rainwater flow to cartridge filter 304 when rainwater flow is great, the life of extension cartridge filter 304, and simultaneously, when rainwater flow is great, the bottom of two adjacent filter 303 can be washed away by the rainwater, at this moment, cartridge filter 304 need take place the deformation of certain degree, oval-shaped setting, when making cartridge filter 304 take place deformation, with being connected inseparabler between the filter 303.
The working principle of the invention is as follows: firstly, fixing and installing a filtering and collecting device, installing a filter cylinder 304 below a filter plate 303, aligning a fixing inserted bar 302 on a filter component 3 with a fixing hole 2021 on a secondary fixing support 202, inserting the fixing inserted bar 302 to complete installation of the filter component 3, then lifting a lifting bar 4045 by hand, aligning a limiting fixture block 402 with a limiting fixture groove 2011, aligning a fixing inserted block 403 with a fixing slot 2012, completing installation of the collecting component 4, then covering a well lid 5 on the collecting component 4, and fixing the collecting component 4, namely completing installation of the filtering and collecting device;
after raining, non-point source pollutants caused by domestic wastewater, solid wastes, water and soil loss and the like can flow into a sewer along with rainwater, meanwhile, garbage such as leaves, plastic bags and the like can also flow into the sewer along with the rainwater, and when the rainwater carrying the non-point source pollutants and the garbage such as the leaves, the plastic bags and the like enters a drainage channel 2;
firstly, the garbage such as leaves and plastic bags is filtered through the drain hole 501 on the well lid 5, then rainwater enters the drainage channel 2 along the drain hole 501, at the moment, the collection hopper 401 collects large particles in the rainwater, meanwhile, the rainwater also enters the fixed pipe 4041 through the water seepage hole 4042, the rainwater is continuously gathered in the fixed pipe 4041, so that the water level in the fixed pipe 4041 is continuously raised, a certain buoyancy is provided for the floating ball 4044, at the moment, the floating ball 4044 rises to drive the jacking rod 4045 and the jacking ball 4046 to rise, the rising jacking ball 4046 penetrates through the drain hole 501, the blocked drain hole 501 can be dredged, and the rainwater can smoothly enter the drainage channel 2 without being influenced;
after large particles in rainwater are collected by the collecting hopper 401, small particles can enter the filtering component 3 along with rainwater, and non-point source pollutants in the rainwater are filtered by the filtering plate 303, and the filtering effect of the filtering plate 303 on the non-point source pollutants in the rainwater can be improved because the filtering plate 303 is arranged in a wave shape;
when the rainfall is great, the rainwater can be flushed the bottom of the filter 303 that is the wave setting, at this moment, the rainwater can get into the filter cartridge 304, and gather in the filter cartridge 304, can utilize the filter cartridge 304 to carry out the filtration of non-point source pollutant, the oval-shaped setting of filter cartridge 304, the impact of rainwater flow to the filter cartridge 304 has been alleviateed, the life of extension filter cartridge 304, when the bottom of two adjacent filter 303 is flushed by the rainwater, filter cartridge 304 need take place the deformation of certain degree, oval-shaped setting, when making filter cartridge 304 take place deformation, with being connected inseparabler between the filter 303, and, this closed filtering component 3 has certain water storage capacity, make the rainfall great time, also can carry out the filtration of non-point source pollutant, because the pressure of gathering can accelerate the filter effect to the rainwater.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
