Description
Technical field
The utility model relates to the filter, particularly laminated type slight irrigation water filter that contains the slight irrigation water of impurity such as sandstone, microorganism for filtration.
Background technology
Existing slight irrigation is divided into two kinds of lamination and net formulas basically with water filter, and during filtration, current enter the slight irrigation pipe network again with the filtration hole that linear state directly is combined to form by screen cloth or lamination.This existing slight irrigation can not classified filtering with water filter, and can not guarantee the long-acting work of filter medium, can not stop effectively that linear impurity enters the slight irrigation pipe network, and filter area is less than normal.
The utility model content
The purpose of this utility model is to provide a kind of laminated type slight irrigation water filter, and is rational in infrastructure, can carry out classified filtering, guarantees long-acting work; Current with the operation of dual slope track, can stop effectively that linear impurity enters the slight irrigation pipe network in filter process; Under the situation that the filter medium volume does not increase, increase considerably filter area.
The purpose of this utility model is achieved in that a kind of laminated type slight irrigation water filter, comprise the annular lamellar body, the correspondence of annular lamellar body own is arranging the centre bore that penetrates its lamellar body, in the front of annular lamellar body first fin is being set, first fin by the linearity fin join end to end constitute and adjacent at least two linearity fins not on same straight line so that first fin along dog-leg path extend and closed-loop around centre bore, the first water conservancy diversion groove that penetrates its rib body along its width is being set at first fin, on the front of annular lamellar body, also arranging respectively along different circumference tracks extend and together closed-loop around second fin and the 3rd fin of centre bore, the 3rd fin ring is around first fin, first fin ring is around second fin, the second water conservancy diversion groove that penetrates its rib body along its width is being set at second fin, at the 3rd fin the 3rd water conservancy diversion groove that penetrates its rib body along its width is being set, the back side of annular lamellar body is the plane; In the middle of adjacent two annular lamellar bodies, positive whole fins-first fin that arranges of the back side of the first annular lamellar body and the second annular lamellar body, second fin contacts with the 3rd fin top separately so that do not stay the gap between the back side of the first annular lamellar body and the whole fin, and the cross section in the 3rd duct that surrounds, the 3rd water conservancy diversion groove internal groove side wall and the annular lamellar body back side, the cross section in second duct that the cross section in first duct that the first water conservancy diversion groove internal groove side wall and the annular lamellar body back side surround and the second water conservancy diversion groove internal groove side wall and the annular lamellar body back side surround is rectangular or triangle all, the cross-sectional area in the 3rd duct is greater than the cross-sectional area in first duct, and the cross-sectional area in first duct is greater than the cross-sectional area in second duct.
When the utility model carries out normal filtration work, constituting some annular lamellar bodies of the present utility model is superimposed also compacted, the slight irrigation current are second duct that the 3rd duct of a, first duct that cross-sectional area is b and cross-sectional area are c by cross-sectional area successively, finally enter slight irrigation pipe network (a〉b〉c), slight irrigation water successively by the 3rd, the process in first, second duct flows along dog-leg path.After the utility model work a period of time, by accumulating a certain amount of impurity in first fin, the 3rd fin and second fin and the adjacent formed filtering chamber of two annular lamellar bodies and the duct, therefore, need in time clear up the annular lamellar body.Before the utility model annular lamellar body is cleared up, the lamination that compresses is loosed off, change open groove fully into by compressing the formed filtration of lamination duct mutually, like this, when clean water stream is sprayed to annular lamellar body outer circumferential side from the slit of lamination inside between lamination, just can will accumulate in the impurity that filters in the duct and remove away fully, especially can remove the impurity of easy embedding net formula filter medium.The technical advantage that the utility model annular lamellar body is compared with existing filter medium is: 1. can carry out classified filtering impurity, guarantee the long-acting work of filter medium; 2. current are advanced with the dual slope track in filter process, can stop effectively that linear impurity enters the slight irrigation pipe network; 3. under the situation that the filter medium volume does not increase, increased considerably filter area.
