Abstract
The utility model relates to a filter, which comprises a casing body, a water inlet pipe and a water outlet pipe, wherein, the inner part of the casing body of the filter is provided with a round centrifugal treating pool of which the lower part is conical. A water outlet of the round centrifugal treating pool is arranged on the upper part of the treating pool and is a lateral spraying pipe, the water inlet pipe is connected inside from the upper part of the centrifugal treating pool, the conical bottom of the pool is provided with a sand elimination pipe, the inner part of the casing pipe of the lower part of the outer part of the centrifugal treating pool is provided with a filter layer, and the filter layer and the casing body form a filter pool. The utility model firstly discharges coarse sand stones in water, then filtering by the filter layer is carried out, and filtering effect is good. If a back flushing is added, the function of back flushing can be realized.
Description
The utility model relates to a kind of filter.
Along with the rise of water-saving agriculture, the drip irrigation and spray irrigation technology is just used more and more widely, because the specific (special) requirements of drip irrigation and spray irrigation, the filtration of water is just seemed very important.
The purpose of this utility model provides a kind of simple in structure, and the filter of cleaner water can be provided to drip irrigation and spray irrigation equipment, especially can handle the filter of river, water in a canal etc.
The utility model comprises shell body, water inlet pipe, outlet pipe, it is characterized in that being provided with in the filter housing body bottom is conical circular centrifugal treating pond, the delivery port in this centrifugal treating pond is located at the top of treatment pond, it is a horizontal shower, described water inlet pipe inserts from the top in centrifugal treating pond, the conical base in pond is provided with the sediment outflow pipe, is provided with filter course in the shell body of the bottom outside the centrifugal treating pond, forms filtering ponds with shell body.
At the external backwash return pipe that preferably is provided with of above-mentioned filter housing, the two ends of this backwash tube are connected on sediment outflow pipe and the blast pipe, are provided with valve between the interface of backwash tube and sediment outflow pipe and the filter.
Outlet pipe place at above-mentioned filter preferably is provided with the cascade filtration device, is made up of shell body and filtration web-roll core.
Filter of the present utility model and cascade filtration device best combination are used, and promptly form one group by a plurality of filters, and its outlet pipe place is provided with the combination of a plurality of cascade filtration devices.
Compared with prior art, the utility model is at first through the centrifugal action in circular centrifugal treating pond, make grit be deposited in the conical base of preprocessor and discharge from the sediment outflow pipe, removed current behind the smart grit and flowed out from top, circular centrifugal treating pond spray apertures and enter filtering ponds, the water purification after filtering through filtering layer flows out from outlet pipe.If will be better through cascade filtration device filter effect, also can increase backwash tube simultaneously, a plurality of filters and group are used, close the total valve of clear water output, close simultaneously in a plurality of filters in one or several water inlet pipe valve, keep one of them or several water inlet pipe valve open, the clear water in the filter of water inlet pipe valve open can oppositely inject clear water in the filter of water inlet pipe valve closing, dirt in the filter course is gone out, can be realized backwashing function.
Knot platform accompanying drawing describes the utility model and embodiment below.
Accompanying drawing is the structural representation of a most preferred embodiment of the utility model.
With reference to accompanying drawing, the utility model comprises shell body (4), water inlet pipe (1), outlet pipe (9), being provided with a bottom in the filter housing body is conical circular centrifugal treating pond (5), the delivery port in this centrifugal treating pond (3) is located at the top of treatment pond, it is a horizontal shower, described water inlet pipe inserts from the top in centrifugal treating pond, the conical base in pond is provided with sediment outflow pipe (8), be provided with filter course (6) in the shell body of the bottom outside the centrifugal treating pond, be made of the shelves bed in the present embodiment, casting bed and shell body are formed filtering ponds.For realizing backwashing function, at the external backwash return pipe (7) that preferably is provided with of above-mentioned filter housing, the two ends of this backwash tube are connected on sediment outflow pipe and the blast pipe, are provided with valve between the interface of backwash tube and sediment outflow pipe and the filter.For further improving filter effect, preferably be provided with the cascade filtration device at the outlet pipe place of above-mentioned filter, form by shell body, filtration web-roll core (10).For realizing cleaning function under the situation of not interrupting whole filtration system, filter of the present utility model and cascade filtration device best combination are used, and promptly form one group by a plurality of filters, and its outlet pipe place is provided with the combination of a plurality of cascade filtration devices.Present embodiment is made up by two set filters, is connected to three groups of cascade filtration devices at its outlet pipe place.
Embodiment 2:
Present embodiment is made up of the conical circular centrifugal treating pond (5) in shell body (4), water inlet pipe (1), outlet pipe (9), the shell body, the delivery port in centrifugal treating pond (3) is located at the top of treatment pond, it is a horizontal shower, water inlet pipe inserts from the top in centrifugal treating pond, the conical base in pond is provided with sediment outflow pipe (8), is provided with filter course (6) in the shell body of the bottom outside the centrifugal treating pond.
Claims (3)
1, a kind of automatic cleaning strainer, comprise shell body, water inlet pipe, outlet pipe, it is characterized in that being provided with in the filter housing body bottom is conical circular centrifugal treating pond, the delivery port in this centrifugal treating pond is located at the top of treatment pond, be a horizontal shower, described water inlet pipe inserts from the top in centrifugal treating pond, and the conical base in pond is provided with the sediment outflow pipe, be provided with filter course in the shell body of the bottom outside the centrifugal treating pond, form filtering ponds with shell body.
2, filter as claimed in claim 1, it is characterized in that the external backwash return pipe that is provided with of described filter housing, the two ends of this backwash tube are connected on sediment outflow pipe and the blast pipe, are provided with valve between the interface of backwash tube and sediment outflow pipe and the filter.
3, as claim 1 or described filter, it is characterized in that the outlet pipe place of described filter is provided with the cascade filtration device, form by shell body and filtration web-roll core.
