Agricultural non-point source pollution monitoring most importantly samples, and sampling is had to accurate；In order to keep sampling more accurate and side
Just, this filter device is provided with before sampling, the sewage removed in agricultural non-point source pollution contains the sundries such as many gravels.
Firstly, the sewage in agricultural non-point source pollution enters in primary filter 2 through water inlet pipe 1, sewage is along upper shell
The downward helical flow in 203 section, reach lower shell 204 after, due to the special shape of lower shell 204, sewage start along
The before spiral internal inside spin that formed rises, be equivalent to centrifugal action by sewage gravel and other sundries isolate
It goes, the lower part of lower shell 204 enters sand storage chamber 208, and settable helicla flute on the inner sidewall of lower shell 204 makes under sewage spiral
That drops is more smooth；It since sand storage chamber 208 is set as elliposoidal, easily falls, not will cause the accumulation of sandstone；Periodically by lower part
Cleaning is opened, and is cleaned by rinse mouth 207；Under use state, rinse mouth 207 is in off state.After sewage rises
It is flowed out by the outlet pipe 3 after strainer 202 along 203 top of upper shell, the strainer 202 being arranged herein, in order to not falling
Sandstone it is for re-filtering, strainer 202 is set as arc, will not reduce the pressure of sewage, makes sewage smoothly along water outlet
The outflow of pipe 3 enters secondary filter through diaphragm valve A-1.
During filter sewage, diaphragm valve A-1 is opened, and the second net flow valve A-2 is closed, and shutoff valve C -1 is opened, and first
Net flow valve C-2 is closed；At this time there are three types of the operating modes of the first filtration members 4 in secondary filter and the second filtration members 5: only the
The work of one filtration members 4, the first inlet valve B-1 and the first outlet valve B-2 are opened, the second inlet valve B-3 and the second outlet valve B-4
It is turned off；Only the second filtration members 5 work, the first inlet valve B-1 and the first outlet valve B-2 be turned off, the second inlet valve B-3 and the
Two outlet valve B-4 are opened；The work of first filtration members 4 and the second filtration members 5 work at the same time, the first inlet valve B-1, the first water outlet
Valve B-2, the second inlet valve B-3 and the second outlet valve B-4 are opened；First filtration members 4 and second are set in secondary filter
Filtration members 5 are the working efficiencies in order to guarantee filter device, once there is one of damage, another works on；Filtering
When the amount of sewage is excessive, the first filtration members 4 and the second filtration members 5 can also be opened simultaneously.
For ease of description, in the present embodiment, the operating mode of selection is the work of the first filtration members 4, and sewage is along the
After one inlet valve B-1, laminated filter 401 and the first outlet valve B-2 carry out secondary filter, it is flow to sampling pond 7, can be adopted
Sample analysis.
When using after a certain period of time, secondary filter is rinsed, flushing is identical with the process of filtering, can be right simultaneously
First filtration members 4 and the second filtration members 5 are rinsed, and can also individually be rinsed to it；For example, individually being carried out to the first filtration members 4
Rinse, close diaphragm valve A-1, close shutoff valve C -1, open the first inlet valve B-1 and the first outlet valve B-2, close second into
Water valve B-3 and the second outlet valve B-4 opens the second net flow valve A-2；Water pump 6 is opened, water pump 6 can directly adopt in sampling pond 7
Water reuses energy conservation and environmental protection, and water enters the first filtration members 4 by the first net flow valve C-2, passes through the second net flow after being rinsed
Valve A-2 flow to sewer pipe 8, and the other end of sewer pipe 8 can be connected to sewage collection equipment, thus can complete to the first filtration members
4 flushing, it is easy to operate, it is simple and easy.
The embodiment of the above, the only preferred embodiment of the utility model not limit the utility model
Practical range, therefore all equivalent change or modifications done according to structure, feature and principle described in the utility model patent range,
It should be included in present utility model application the scope of the patents.
