Description
Technical field:
This utility model is a kind of to be applicable to the vertical type backwashing filter that impurities in water is filtered by the water systems such as power plant, iron and steel, papermaking, hot-water heating.
Background technology:
The vertical filter filtered impurities in water at present, is all installation drainage screen in a vertical filter cylinder, uses the mode of high in and low out to filter the water containing impurity, is intercepted by impurity on the filter screen in filter cylinder, it is achieved filter effect.The major defect that this traditional vertical filter exists is after the impurity filtered reaches some, it is accomplished by filter cylinder, take out filter screen carrying out clear net, not only dismantle inconvenience, and sealing and filter screen to filter all can affect in unloading process, reduce the service life of filter.
Summary of the invention:
The purpose of this utility model is to provide and a kind of can be carried out filter screen in the case of not dismantling, not shutting down, saves manpower, improves the vertical type backwashing filter of service life of equipment.
nullThe technical solution of the utility model completes as follows，A kind of vertical type backwashing filter，It is characterized in that: it includes a vertical filter cylinder，Filter cylinder inwall is provided with an annular boatswain chair in middle and upper part，One tubular filter screen is installed downwards along inner circle below boatswain chair，Cartridge wall is provided with a water inlet higher than boatswain chair from side，Filter cylinder mouth periphery on water inlet is provided with adpting flange，On flange, it is furnished with one seals upper cover，It is connected between upper cover with flange and has bolt，A piece rotating shaft is installed with filter screen concentric in filter cylinder at upper cover center，Upwards cover upper side connection in rotating shaft upper end and have a crank，In filter cylinder, in rotating shaft, on filter screen inwall, all standing is symmetrically installed with at least two brush，Cartridge wall is provided with an outlet less than boatswain chair in side，It is provided with a blowoff valve at filter cylinder one side bottom.
When this utility model needs to net clearly, only need to shake brush handle, the brush in rotating shaft filter screen is carried out, the impurity brush on filter screen is fallen, the blowoff valve bottom filter cylinder rolls out, have time saving and energy saving, efficient and convenient, prevent because of the advantage of dismounting infringement parts.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment is described in detail in conjunction with accompanying drawing, it includes a vertical filter cylinder 1, filter cylinder inwall is provided with an annular boatswain chair 3 in middle and upper part, one tubular filter screen 2 is installed downwards along inner circle below boatswain chair, cartridge wall is provided with a water inlet 4 higher than boatswain chair from side, filter cylinder mouth periphery on water inlet is provided with adpting flange 5, on flange, it is furnished with one seals upper cover 7, it is connected between upper cover with flange and has bolt 6, a piece rotating shaft 9 is installed with filter screen concentric in filter cylinder at upper cover center, upwards cover upper side connection in rotating shaft upper end and have a crank 8, in filter cylinder, in rotating shaft, on filter screen inwall, all standing is symmetrically installed with at least two brush 10, cartridge wall is provided with an outlet 11 less than boatswain chair in side, it is provided with a blowoff valve 12 at filter cylinder one side bottom.This structure, when fluid is through out-of-date, is got lodged in filter screen by the impurity of strainer filtering, after impurity reaches some, when causing network blocking, rotate as long as grasping crank, filter screen will be scrubbed by the brush in rotating shaft, and impurity runs past and discharged by blowoff valve bottom filter screen following current body inflow filter cylinder.Clean filter screen process to need not dismantle filter, it is not required that shut down, the most time saving and energy saving, be conducive to again improving the service life of drainage screen.
