Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, a kind of PLC technology automatic back-flushing filtering device, is comprised the backwash filter unit 3 of robot control system(RCS) unit 1 and several backwash filter modules 2 composition, is connected between backwash filter unit 3 and robot control system(RCS) unit 1 by holding wire; Backwash filter unit 3 is respectively arranged with upstream pressure and detects mouth 16 and downstream pressure detection mouth 17; Robot control system(RCS) unit 1 comprises control cabinet 4, and control cabinet 4 surface is provided with human-computer interaction module 5, and control cabinet 4 inside is provided with power module, Programmable Logic Controller, relay and differential pressure pickup, and wherein, the model of Programmable Logic Controller is mitsubishi FX2N; Differential pressure pickup detects mouth 16 and downstream pressure respectively by wire and detects mouth 17 and be connected with upstream pressure; Power module is used for AC/DC conversion, and 220V civil power is converted into 24V direct current; Programmable Logic Controller is connected with human-computer interaction module 5, thus reaches human-computer interaction function; Differential pressure pickup is by the Signal transmissions that detects to Programmable Logic Controller, and Programmable Logic Controller sends the opening and closing of instruction Controlling solenoid valve.
As shown in Figure 2, backwash filter module 2 comprises the pipeline group be formed by connecting by water inlet pipe 7 and outlet pipe 13, is disposed with filter electromagnetic valve 10 and blow-off pipe 14, blow-off pipe 14 is provided with blowoff electromagnetic valve 15 between water inlet pipe 7 and outlet pipe 13; Filter 12 is provided with between blowoff electromagnetic valve 15 and outlet pipe 13; Water inlet pipe 7, to be connected by loose joint 11 between blow-off pipe 14 and outlet pipe 13; The water inlet of water inlet pipe 7 is provided with Pressure gauge 6 and support 8, and the end of support 8 is provided with lower margin 9.
As shown in Figure 3, also connected by loose joint 11 between backwash filter module 2.
In the utility model, water inlet pipe, outlet pipe and blow-off pipe can according to materials such as the optional PVC-U of different application field divided parts material, PP-R, sanitation-grade stainless steels.
The operation principle of a kind of PLC technology automatic back-flushing filtering device of the utility model is: during system cloud gray model, water enters backwash filter unit 3 by water inlet pipe 7, first each group of filter electromagnetic valve 10 of opening is flow through, then each set filter 12 is arrived inner, internal screen adheres to particle such as interception impurities in water or sandstone etc., and the water now being completed filtration by filter screen is flowed out can supply use through outlet pipe 13.In filter process, filter screen builds up the impurity such as the sandstone in water, form impurity screening layer, because impurity layer is deposited in the inner side of filter screen, therefore a pressure reduction is just defined in the inside and outside both sides of fie screen, the i.e. pressure differential of upstream pressure and downstream pressure, when the pressure reduction that upstream pressure is greater than downstream pressure reaches preset value, performs automatic backwash process by starting.As shown in Figure 3, (filter electromagnetic valve 10 cuts out in the magnetic valve action of now A group backwash filter module 2, blowoff electromagnetic valve 15 is opened), the magnetic valve of B group backwash filter module 2 continues to be that filtration condition (open by filter electromagnetic valve 10, blowoff electromagnetic valve 15 is closed), a water part through the filtration of B group backwash filter module 2 flows out supply and uses, the filter 12 that another part water then oppositely flows into A group backwash filter module 2 is inner, back flush is carried out to internal screen, the impurity be attached on filter screen is rinsed well, by blow-off pipe 14, above material is discharged.Water purification supply around here continues to flow, and at the end of cleaning, blowoff electromagnetic valve 15 is closed, and filter electromagnetic valve 10 is opened, and filter 12 starts to perform the backwash of B group backwash filter module 2, and cleaning way is alternate run.If any the more backwash filter modules 2 of expansion, to the last one group of backwash terminates, and filter 12 just can be next backwashing period and prepares.
In addition, backwash also selecting time cyclic pattern backwash is carried out to filter 12.User only need carry out the switching of mode of operation by the human-computer interaction module 5 of robot control system(RCS) unit 1, the parameter of setting cycle time and backwashing time, just execution cycle property backwashing function.
If in use water quality is poor, now user can increase the filter area of filter to improve filtering accuracy.Its method as shown in Figure 4, installs multiple backwash filter module, forms high efficiency filter pipe network system, reaches water quality demanding criteria.
