Detailed description of the invention
As depicted in figs. 1 and 2, full-automatic back washing filter includes cylinder barrel 5, water inlet pipe 7, outlet pipe 8, air motor 1, the filter element 14 of tubulose and control chamber 6, outlet pipe 8 and water inlet pipe 7 are separately positioned on the both sides of cylinder barrel, air motor 1 is fixed on the motor fixing base 2 at cylinder barrel top, and control chamber 6 is fixed on cylinder barrel sidewall；Air motor 1 output shaft connects blow-off pipe 11 and drives blow-off pipe 11 to rotate, and is provided with the pallet 15 of vertical inner wall of cylinder in the middle part of inner wall of cylinder, and pallet external diameter is equal to inner wall of cylinder diameter；Filter element 14 is provided with multiple, and around being connected on pallet 15, each filter element all equidistant with tray center, the bore of each filter element mouth of pipe is equal；Being provided with the bottom 17 being parallel to pallet below pallet 15, bottom, by being fixedly welded on inner wall of cylinder, bottom top supports many connecting bolts 16, and the screw thread on connecting bolt top is used for connecting trays 15, and connecting trays is supported by these many connecting bolts 16；Connecting on blow-off pipe 11 lateral wall and have bend pipe 18, upward, this outlet is equal with the centre-to-centre spacing of blow-off pipe with the centre-to-centre spacing of blow-off pipe 11 and filter element in the outlet of bend pipe；Being equipped with pressure transducer at described water inlet pipe 7 and outlet pipe 8 mouth of pipe, pressure transducer connects control chamber 6 internal controller；Controller 6 judges and controls the startup of air motor, stopping, rotating speed, the open and close of control electromagnetic valve according to the pressure differential of the inlet tube and outlet tube mouth of pipe.
Between filter element 14 and pallet 15 with bolts；Being welded with pallet axle sleeve 13 on pallet, blow-off pipe connects at the top of pallet axle sleeve inner pallet axle sleeve 13 packing ring 12.
Between described blow-off pipe 11 and cylinder barrel 5 top cover, junction is provided with mechanical seal 10；The bottom connecting bend 20 of blow-off pipe, elbow 20 connects straight tube, and this straight tube stretches out outside cylinder barrel through cylinder barrel 5, and cylinder barrel connects pneumatic operated valve, and pneumatic operated valve is opened and closed automatically by control chamber control realization.
Described water inlet pipe 7 is between pallet 15 and bottom 17；Water inlet pipe 7 is arranged on the lower section of outlet pipe, the top of blow-off pipe outlet 19.
Further as it can be seen, air motor 1 is fixed on motor fixing base 2, motor fixing base 2 is bolted with cylinder cap 3.Cylinder cap 3 and cylinder barrel 5, connected by connecting bolt 4, and control chamber 6 is welded on cylinder barrel 5.Water inlet pipe 7 and outlet pipe 8 are welded by adpting flange and straight-run of pipe, are respectively welded at the both sides of cylinder barrel.Air motor 1 drives blow-off pipe 11, is attached across cylinder cap 3 and cylinder barrel 5 by mechanical seal 10, and packing ring 12 is connected with pallet axle sleeve 13, welded together with pallet 15.The lower end of blow-off pipe 11 through bottom 17 by mechanical seal, is connected with elbow 20, is finally connected with pneumatic operated valve 9, blowdown.Elbow 20 welds together with bottom 17.The mode being threaded connection on pallet 15 is equipped with several filter elements 14.Pallet 15 is connected by connecting bolt 16 with bottom 17.Bottom 17 is welded on cylinder barrel 5.
During normal filtration, water flows into through filter element filtering from water inlet pipe, flows out from outlet pipe.And when filter element have accumulated certain impurity, when affecting filter effect, namely when the value that pressure difference switch in the difference of intake pressure and discharge pressure reaches this filter control chamber sets, pressure difference switch is opened, and controls air motor work, air motor drives blow-off pipe to rotate, interface below blow-off pipe is connected with certain filter element, filter cartridge flushing when water flows through filtration core, and now the pneumatic operated valve of blow-off pipe is opened, impurity is discharged through blow-off pipe, has reached the effect of filter cartridge flushing.Meanwhile, other filter element is still carrying out filtration work, and the water after filtering is discharged through outlet pipe.Air motor drives blow-off pipe to rotate by certain speed, blow-off pipe the most successively be rinsed blowdown to each filter element.The most do not affect system work, moreover it is possible to reach the effect of backwash.
The full-automatic back washing filter of this pneumatic control that the present invention relates to, pneumatic source can be by the compressed air in dry fog system, preferably and dry fog system globe area, eliminates complicated road of connecting wires, and system is safer, more stable has reached explosion-proof requirement.
Detailed description of the invention of the present invention is not intended that the restriction to the application scope; within every spirit at present inventive concept and principle, any amendment, equivalent and improvement etc. that one of skill in the art can make should be included within the scope of the present invention.
