As shown in Figure 1 and Figure 2, filter element comprises main body 1, and 4 filter cylinders and element kit 4 are installed on the main body 1, and filter cylinder and element kit 4 are provided with blowdown apparatus.The quantity of filter cylinder and element kit 4 is not limited to 4, can be 3,5,6,8 etc., or more quantity.
As shown in Figure 3, Figure 4, vertically have inlet opening Pin, fluid hole Pout and mudhole 12 in the main body 1.Have installation position 16 on the main body 1, be used to install filter cylinder and element kit 4, filter cylinder and element kit 4 are provided with blowdown apparatus, and blowdown apparatus is loaded on the bottom of described filter cylinder and element kit 4, can connect by the mode that is threaded, also can be with other connected mode.The middle part of blowdown apparatus is hollow, and the bottom is provided with blowdown apparatus control valve 6, is provided with filter core compressing member 20 between blowdown apparatus and the filter core, after blowdown apparatus is packed filter cylinder and element kit 4 into, can filter core upwards be compressed by filter core compressing member 20.Filter core compressing member 20 also can be that an end has rib-loop, the other end is hollow hexahedron, has through hole on six sidewalls of hollow hexahedron, is used for blowdown, with interior six side's planks rotate this part can be between filter core and filter cylinder stretching, prevent that filter core from axially being broken by hydraulic coupling.Filter core compressing member 20 also can be the hollow cylinder of other shape, as cylinder, multi-faceted column etc.
Also have many Hydraulic Elements interface channels in the main body 1, be used to connect Hydraulic Elements, as main control valve, filter cylinder and element kit, electronic control volume, electromagnetic priority valve, pressure sensor, Pressure gauge, pollution warning sprayer etc., each Hydraulic Elements can be installed top, below, the place ahead, rear and the two ends, the left and right sides etc. with main body 1.
Again referring to Fig. 1, Fig. 2, the structure of a specific embodiment is to comprise main body 1, main control valve 2, electronic control volume 3, filter cylinder and element kit 4, electric controller 5, blowdown apparatus control valve 6, electromagnetic priority valve 7, pressure sensor 8, Pressure gauge 9, pollute warning sprayer 10, joint commutation pipe fitting 11, mudhole 12, blowdown apparatus 13, support 14 etc.
Be that a filter element uses separately in the present embodiment, 9,2 pressure sensors 8 of 2,2 Pressure gauges of 2 main control valves are installed in the top of main body 1,2 electronic control volumes 3 are respectively installed to 2 main control valve 2 end faces, and 2 electromagnetic priority valves 7 are respectively installed to again on 2 electronic control volumes 3.Insert 1 in the side of main body 1 and pollute warning sprayer 10, below main body 1, mount 4 filter cylinders and element kit 4.More than all are installed to parts on the main body 1 directly, indirectly, be installed to 14 li on support by main body 1.Rubber hose is convenient establishes joint commutation pipe fitting 11 for external major diameter steel wire twines, and the one end inserts main body 1, and the other end is fixed on the support 14.Wherein, main control valve 2 is to merge 34 logical valves that form by two 23 logical valves.
Main characteristics of the present invention is with main body 1 other necessary parts to be fused, and has saved the complex pipeline connection.The above embodiments are electronic automatic control backwash processes.In another embodiment, can adopt manual control backwash process, like this, can remove elements such as electronic control volume 3, electromagnetic priority valve 7, pressure sensor 8, further simplified structure.
The contrast accompanying drawing is described in detail the operation principle of these two kinds of embodiment below:
Specific embodiment one as shown in Figure 5, is the schematic diagram of electronic automatic control backwash process, and inlet opening Pin is connected with element kit 4 with filter cylinder by main control valve 2 respectively with mudhole 12.
The control liquid road of described main control valve 2 is provided with electronic control element, and electronic control element comprises electronic control volume 3, electromagnetic priority valve 7, and electronic control volume 3 is located on the control liquid road of main control valve 2, by the commutation of the electronic control volume 3 of electromagnetic priority valve 7 controls.
Inlet opening Pin and fluid hole Pout can be connected with pressure sensor 8 respectively, be used to detect the hydraulic pressure of inlet opening Pin and fluid hole Pout, when the pressure differential that detects inlet opening Pin and fluid hole Pout when pressure sensor 8 is higher than preset threshold, electromagnetic priority valve 7 actions, and control 3 commutations of electronic control volume, backwash is carried out in the control liquid road pressure release of main control valve 2.
Can also be connected with between inlet opening Pin and the fluid hole Pout and pollute spraying alarm 10, when the pressure differential of fluid hole Pout and inlet opening Pin is higher than preset threshold, pollutes 10 sprayings of spraying alarm and report to the police, prompting should be carried out backwash.
Specific embodiment two as shown in Figure 6, is a schematic diagram of manually controlling backwash process, and the control liquid road of main control valve 2 is provided with manual control valve 15, and when opening manual control valve 15, the control liquid road pressure release of main control valve 2 can be carried out backwash.Because main control valve 2 adopts the guide to control 23 logical valves, and have two 23 logical valves to merge into one 34 logical valves, operating personnel turn handwheel lightly with hand, just can realize the backwash of manual backwash high pressure filtering station.Avoided large diameter 23 pass ball valves of available technology adopting, operating personnel move the difficulty of handwheel, also are automatically controlled the providing convenience of realization with this main control valve.
No matter be electronic automatic backwash high pressure filtering station among the present invention, or manual backwash high pressure filtering station, its guide's control is not to pressure, but pressure release.
Backwash high pressure filtering station of the present invention, simple and compact for structure, volume is little, pipeline connects fewly, and the spraying of pollution warning device is arranged.Can also dispose electronic automatic backwash and manual back purge system simultaneously, can realize manually by the backwash of electromagnetic priority valve button, manually by the backwash of electric controller button, manually sequential control backwash, timing controlled automatic backwash, pollute a plurality of functions such as pressure reduction control automatic backwash.The filter cylinder area is big, and water environment capacity is strong, and the down blow function is arranged.
Among the present invention, a basic filter element with 4 filter cylinders and element kit, flow can reach 1000L/min, during in parallel 2 basic filter elements, just constitutes the filter station of 2000L/min.Certainly, basic filter element can a plurality of filter cylinders of following extension and element kit, and a plurality of basic filter elements can in parallelly use, and form bigger filter station.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
