Fig. 2 is the vertical view by filter shown in Figure 1.
Number in the figure:
1 is the water inlet butterfly valve, and 2 is filter, and 3 are the blowdown flexible pipe, and 4 are the maintenance hand hole, and 5 is hydroman, and 6 are the water outlet butterfly valve, and 7 is bypass pipe, and 8 is bypass regulator valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to Fig. 1 and Fig. 2, a kind of Y type self-cleaning filter of the present utility model mainly is made up of parts such as casing, filter 2, water inlet butterfly valve 1, blowdown flexible pipe 3, maintenance hand hole 4, hydroman 5, water outlet butterfly valve 6, bypass pipe 7, bypass regulator valves 8.
The inside of filter 2 is provided with net-filter assembly.The filter screen skeleton is made by stainless steel or engineering plastics, and filter screen is at least a in plain net, seat type net, the Z type net.The filtering accuracy of screen pack is 50 to 3000 microns.The material of screen pack is a stainless acid resistant steel.The cylindrical shell skeleton of net-filter assembly is the ABS engineering plastics.
The pipeline at filter 2 two ends is communicated with a bypass pipe 7, and an end of bypass pipe 7 is provided with bypass regulator valve 8.The surfaces externally and internally spraying epoxy polyester material of filter 2 can guarantee that like this product prevents the housing corrosion under abominable condition of water quality, and the succinct light in surface, is convenient to cleaning.
Blowdown flexible pipe 3 is a tubular part, and this tubular part is positioned at the casing core, and an above pollution-absorbing nozzle is housed on tubular part, and pollution-absorbing nozzle is facing to the fie screen inner face of net-filter assembly.
Hydroman is arranged on the casing outside.Hydroman detects the differential water pressures between the two-layer filter screen in the net-filter assembly, and the open and-shut mode of control bypass regulator valve.
Maintenance hand hole 4 is arranged on the low side of filter 2.Suspension ring are arranged on the position of centre of gravity of filter 2.
In the present embodiment, the casing of Y type self-cleaning filter is tubular, links to each other with water inlet pipe and water outlet pipe, is the critical piece of filter.Casing selects for use mild steel to make, and mainly is in order to guarantee product strength and weldability preferably.Housing has the movable hand hole of maintenance and maintenance usefulness, is convenient to operation.The housing seal element all adopts oil resistant rubber goods, good airproof performance, long service life.At the casing position of centre of gravity suspension ring are set, so that the product lifting is moved.
Net-filter assembly in the filter is the core component of filter, and its cylindrical shell skeleton is made with 0Cr18ni stainless steel or ABS engineering plastics, can be divided into plain net, seat type net, Z type net etc. by different filtering waters and requirement; Can in 50～3000 micrometer ranges, select by different filtering accuracies.The filter screen material is selected stainless acid resistant steel (0Cr18Ni9,1Cr18Ni9T) for use, can guarantee that filter screen has enough intensity and durable in use.
Filter screen and plastic skeleton melt technology with high frequency induction thermal to be finished, and it can guarantee filter screen and skeleton strong bonded, guarantees that filter screen does not deform in long-time, aliquation, come off etc.
Blowdown flexible pipe in the filter is a tubular part that places the product core, by the different flow requirement required pollution-absorbing nozzle is set, its function be the impurity dirt in the filter screen is collected and the discharge machine outside, it uses the stainless steel material manufacturing, can satisfy that it is corrosion-resistant, the aging-resistant requirement.
Rotary motor is provided in a side of an impeller body at blowdown flexible pipe rear portion, and the reaction force that it uses externally discharged waste water can make the rotation of blowdown flexible pipe, so that the blowdown flexible pipe is done the soil pick-up action in 360 ° of scopes.Blowdown apparatus is made up of blowoff valve and pipeline, and it is taken action under the instruction of control system, finishes unlatching---time-delay---closing function.
The course of work of Y type self-cleaning filter of the present utility model is as follows:
When the utility model used, water was entered by inlet, at first filtered the impurity of larger particles through coarse strainer, arrived fie screen then.In filter process, fie screen builds up foul, the impurity in the water, forms the impurity screening layer, because impurity layer is deposited in the inboard of fie screen, has therefore just formed a pressure reduction in the inside and outside both sides of fie screen.
When the pressure reduction of filter reaches preset value, automatic control system feeds back to pressure reduction cleaning and the blowdown apparatus that connects filter, this moment, blowoff valve was opened, cleaning device is worked simultaneously, begin automatic cleaning process, water purification supply around here continues to flow, because blowoff valve communicates with atmosphere, hydraulic pressure descends in blowdown chamber and the blowdown flexible pipe, form the pressure differential of a filter cylinder and dirt sucking tube, this pressure differential produces a powerful sucking power on the pollution-absorbing nozzle mouth, this sucking power is piled up the impurity layer on the filter cylinder inwall outside the aspiration machine, just forms a soil pick-up process.
Simultaneously, hydraulic motors drive dirt sucking tube is for the helical movement vertically, and the blowdown flexible pipe is done axially-movable and combining of rotatablely moving, and cleans up fully in whole filtering net inner surface scope, and whole cleaning process was finished in 6～10 seconds.
Blowdown apparatus is after cleaning finishes, and pressure reduction disappears in the system, and blowoff valve cuts out, and enters another and filters the work period.
In summary, Y type self-cleaning filter of the present utility model have automatic pollution discharge, need not external impetus, an advantage such as adaptability is good, functional, safe and reliable, the system that can guarantee continues to flow is installed.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
