Abstract
The utility model discloses an automatic backwash sewage filter, which comprises a semilunar valve, a diverting plate, a filter screen, a pollution discharge diverting plate, a pollution discharge semilunar valve, and a pollution discharge valve, wherein the semilunar valve is coaxially connected with a semilunar valve hand-wheel, the diverting plate is rectangle and divides a tube, a pollution discharge opening and the filter screen into two parts, the filter screen is vertically connected with the diverting plate, the circumference of the filter screen is connected with the inner wall of the tube, and the pollution discharge diverting plate divides the pollution discharge opening and the pollution discharge tube into two parts and is connected with the diverting plate in the pollution discharge opening at the same plane. The utility model has the advantages of simple structure, easy operation and good filter property, and the utility model can automatically backwash filter screen and discharge impurity and sewage easily, so the utility model is suitable for any water supply system.
Description
Technical field
The utility model relates to a kind of automatic backwash drain filter.Be applicable to that impurity screening guarantees that water system normally moves, can also be to the screen pack backwash and with outside impurity and the dirt discharge pipe.
Background technology
In the water supply piping system, strainer plays the important function that impurity screening guarantees quality of water supply, protection rear portion equipment.Strainers such as common Y type or T type all can not be accomplished not disassembly, cleaning blowdown, and screen pack is because the accumulation of impurity often influences the normal operation of system.A kind of patent No. is 99237249.6 utility model " automatic pollution discharge filter ", and it is made up of cylindrical shell, first quarter moon valve, flow distribution plate, screen pack, sewage draining exit interlock cover plate, drive unit, blowoff valve, end cap.On cylindrical shell, be provided with water inlet and delivery port and sewage draining exit, end cap be housed at an end of cylindrical shell.It is characterized in that the first quarter moon valve in the cylindrical shell links to each other with drive unit, the first quarter moon valve links to each other with sewage draining exit interlock cover plate, the first quarter moon valve links to each other with flow distribution plate, flow distribution plate links to each other with cylindrical shell, sewage draining exit interlock cover plate links to each other with blowoff valve, flow distribution plate links to each other with screen pack, and blowoff valve is installed in the junction of sewage draining exit and blow-off line.By drive unit, the position that changes the first quarter moon valve can reach the effect of automatic backwash blowdown.But in actual applications, because its link gear, makes that the control of sewage draining exit interlock cover plate is easy to failure easily by impurity and dirt retardance.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic backwash drain filter, and strainability is good, to the screen pack automatic backwash, easily with outside impurity and the dirt discharge pipe.
In order to achieve the above object, the utility model adopts following technical measures:
Form by water inlet, first quarter moon valve, first quarter moon valve hand wheel, sewage draining exit, body, flow distribution plate, screen pack, delivery port, blowdown flow distribution plate, blowdown first quarter moon valve, blow-off pipe, blowoff valve.It is characterized in that the first quarter moon valve links to each other with the first quarter moon valve hand wheel is coaxial.Flow distribution plate is a rectangular metal sheet material, and body inside is divided into two, and the inwall with body is welded to connect up and down, and body is for having seam or seamless steel pipe.Flow distribution plate is divided into two sewage draining exit simultaneously, also screen pack is divided into two.Screen pack closely is connected with flow distribution plate is vertical, also closely is connected with inboard wall of tube body around it.In addition, the blowdown flow distribution plate is divided into two sewage draining exit and links to each other in the sewage draining exit isoplanar with flow distribution plate with blow-off pipe.The upper end of blow-off pipe and sewage draining exit coincide and weld.The blowdown flow distribution plate is welded to connect in blow-off pipe.Blowdown first quarter moon valve is installed in the lower end of blowdown flow distribution plate.
The utility model compared with prior art has simple in structurely, easy to operate, occupies little space, advantage such as setting height(from bottom) is low, and result of use is good.Because its sewage backwash function has avoided strainer to stop up because of long-time the use, causes the trouble of disassembly, cleaning or replacing screen pack.The utility model is applicable to any water system.
Description of drawings
Fig. 1 is the schematic diagram of automatic backwash drain filter.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
According to Fig. 1 as can be known, first quarter moon valve 2 and 3 coaxial linking to each other of first quarter moon valve hand wheel.Flow distribution plate 6 is a rectangular metal sheet material, and body 5 inside are divided into two, and the inwall with body 5 is welded to connect up and down, and body 5 is for having seam or seamless steel pipe.Flow distribution plate 6 is divided into two sewage draining exit 4 simultaneously, also screen pack 7 is divided into two.Screen pack 7 and flow distribution plate 6 are vertical closely to be connected, and also closely is connected with body 5 inwalls around it.In addition, blowdown flow distribution plate 9 is divided into two sewage draining exit 4 and links to each other in sewage draining exit 4 isoplanars with flow distribution plate 6 with blow-off pipe 11.The upper end of blow-off pipe 11 and sewage draining exit 4 coincide and weld.Blowdown flow distribution plate 9 is welded to connect in blow-off pipe 11.Blowdown first quarter moon valve 10 is installed in the lower end of blowdown flow distribution plate 9.Rotation first quarter moon valve hand wheel 3, first quarter moon valve 2 cuts out the latter half of body 5, a current part flows out through first half, the first half of screen pack 7, the delivery port 8 of water inlet 1, body 5, the latter half of another part backflow washing filter screen 7, impurity and dirt are discharged through the latter half and the blowoff valve 12 of sewage draining exit 4 and blow-off pipe 11.Rotation first quarter moon valve hand wheel 3, first quarter moon valve 2 cuts out the first half of body 5, a current part flows out through latter half, the latter half of screen pack 7, the delivery port 8 of water inlet 1, body 5, the first half of another part backflow washing filter screen 7, impurity and dirt are discharged through the first half and the blowoff valve 12 of sewage draining exit 4 and blow-off pipe 11.Rotate blowdown first quarter moon valve 10, can close front or rear half part of blow-off pipe 11, the discharge of control impurity and dirt.The driving of first quarter moon valve 2, blowdown first quarter moon valve 10 and blowoff valve 12 can be manual, pneumatic or electronic.Sewage backwash cycle and time length can be by program or sensor sensing controls.First quarter moon valve 2 is a sheet metal, after the installation, can be axe movement with the perpendicular end surface of flow distribution plate 6, closes front or rear half part of body 5.Blowdown first quarter moon valve 10 is a sheet metal, after the installation, can be axe movement with the lower end surface of blowdown flow distribution plate 9, closes front or rear half part of blow-off pipe 11.First quarter moon valve 2 and screen pack 7 lay respectively at water inlet 1 end and delivery port 8 ends of flow distribution plate 6 in body 5.Sewage draining exit 4 is between first quarter moon valve 2 and screen pack 7.Screen pack 7 usefulness are made by wire gauze or metal perforated plate.
