Affiliated technical field:

The utility model relates to a kind of filtration cycle water device, relates in particular to a kind of twin-channel drainage utensil that automaticallyes switch and clean automatically that has.

Background technology:

Conventional at present several self-cleaning drainage utensils generally adopt the single channel form; it is one side water inlet another side water outlet of passage; several citation forms that single dirt, double dirt, single filter cylinder, many filter cylinders are arranged again, they all have a common weak point, after backwash; if the front and back differential pressure still can not be fallen; overhaul with regard to shutting down, filter cylinder is taken out laggard pedestrian worker clean, refill use; on-line operation influences normal technical water supply so continuously.

Summary of the invention:

The utility model provides a kind of binary channels to clean the drainage utensil automatically, its objective is to overcome the deficiencies in the prior art, and a kind of twin-channel drainage utensil that can continuous on-line automatic operation that can effectively carry out automatic pollutant removal, blowdown is provided.

For realizing goal of the invention, the technical solution of the utility model is:

A kind of binary channels is cleaned the drainage utensil automatically, comprises cylindrical shell, it is characterized in that: establish dividing plate in the cylindrical shell, dividing plate is divided into two isolated cavitys with cylindrical shell becomes two passages; Passage has water inlet and delivery port, be installed with filter cylinder in the passage, also be provided with the rotating shaft that is provided with the blowdown suction nozzle of passing filter cylinder in the passage, rotating shaft is connected with drive motors, the passage below is provided with the blow-off pipe that is connected with electronic Blowoff ball valve, is provided with differential pressure controller in the passage; The water inlet of two passages is connected with pipeline with same water inlet electric three-way ball valve; The differential pressure controller of establishing in the drive motors of two passage correspondences, two passages, the electronic Blowoff ball valve of two passage correspondences, above-mentioned water inlet electric three-way ball valve all are connected with same PLC control cabinet able to programme.

The beneficial effects of the utility model: realized binary channels self-cleaning filtration; Then passage I water inlet, filtration, water outlet when coming water to get to passage I through the electric three-way ball valve, according to setting differential pressure, duty parameter regularly,, then carry out the backwash dirt eliminating function of removing contamination automatically if reach when setting duty parameter, passage II is not then intake, and can overhaul; When passage I need overhaul, water inlet electric three-way ball valve can be got to passage II, and then passage II advances water, filtration, water outlet, the automatic backwash dirt eliminating function of removing contamination; Two passage I, II can realize the using and the reserved function; The utility model can be realized control function automatically such as single channel water inlet, filtration, backwash, blowdown, can also decide differential pressure or regularly carry out the automatic switchover of passway.This device is real realizes unattended on-line continuous operation, and this device practicality simultaneously, installation, dismounting, maintenance are all very convenient, greatly improve the efficient that continuous water supply filters.

Realize the on-line continuous operation function, overall structure is simple, and is safe in utilization, and installation, dismounting, easy to maintenance have improved continuous water supply drainage efficient.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an Inlet and outlet water apparatus structure schematic diagram;

Fig. 3 is the utility model control system schematic diagram.

The specific embodiment:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Fig. 1, Fig. 2, Fig. 3, the utility model comprises cylindrical shell 8, establish the dividing plate 18 of setting in the cylindrical shell 8, dividing plate 18 is divided into two passages with cylindrical shell 8: passage I, passage II, and adopt the flange bolt modes to connect formation with cylindrical shell 8 with two top boards 11 to make passage I, passage II become two cavitys; Passage I, passage II structure are identical.

Passage has water inlet 100 and delivery port 200, be installed with filter cylinder 10 in the passage, the filter cylinder that filter cylinder 10 is fixed by bolts in the cylindrical shell 8 supports on ring flat-plate 19 and the filter cylinder fixed ring plate 17, also be provided with the rotating shaft that is provided with the blowdown suction nozzle 9 of passing filter cylinder 10 in the passage, rotating shaft 9 is set up in cylindrical shell 8 with top chock 12 and step 7, rotating shaft 9 upper ends are connected with drive motors 300 by shaft coupling 13, cycloidal-pin wheel decelerator 14, the passage below is provided with the blow-off pipe 4 that is connected with electronic Blowoff ball valve 5, is provided with differential pressure controller 500 in the passage.Cylindrical shell 8 bottoms of passage I, passage II correspondence are designed the maintenance hand hole respectively, and the cylindrical shell top is the designing and arranging air valve respectively.

The water inlet 100 of passage I, passage II is connected with pipeline 2 with same water inlet electric three-way ball valve 1; The delivery port 200 of passage I, passage II is connected with pipeline 3 with same water outlet electric three-way ball valve 6; The electronic Blowoff ball valve 5 of two differential pressure controllers 500 establishing in two drive motors 300 of passage I, passage II correspondence, passage I, the passage II, passage I, passage II correspondence, water inlet electric three-way ball valve 1, water outlet electric three-way ball valve 6 all are electrically connected with same PLC control cabinet 400 able to programme also all by PLC control cabinet 400 controls able to programme.

When the utility model carried out work, water entered into water inlet electric three passes ball valve 1 through water pump, when water inlet electric three passes ball valve 1 switches to passage I, from water inlet pipe 2 admission passage I bottoms, flowed out through delivery port electric three passes ball valve 6 from outlet pipe 3 through filter cylinder 10.Filter medium is entered by filter cylinder 10 inboards, through behind the multiple filtration, solid suspension in the liquid is trapped within filter cylinder 10 inwalls, because of increasing gradually, dirt cause filter inlet and outlet pressure difference to increase, this pressure difference data detects and is transported to PLC control cabinet 400 able to programme by differential pressure controller 500, when pressure reduction reaches setting value, PLC control cabinet 400 able to programme sends the drive motors 300 of signal enabling passage I correspondence, by cycloidal-pin wheel decelerator 14, shaft coupling 13 drives rotating shaft 9 and rotates, the blowdown suction nozzle goes to filter cylinder 10 belows, PLC control cabinet 400 able to programme sends the electronic Blowoff ball valve 5 that signal is opened passage I correspondence simultaneously, cause the pressure in this filter cylinder 10 sharply to descend, this moment, filter cylinder 10 inside and outside differential pressures increased rapidly, the outer water purification of tube carries out powerful backwash to this filter cylinder 10, moment can thoroughly clean up backwash impurity with dirt in the filter cylinder 10, sediment is discharged from passage I bottom blow-down pipe 4.Return to set condition up to pressure reduction, PLC control cabinet 400 able to programme sends the drive motors 300 that signal stops passage I correspondence.

Filter inlet and outlet pressure difference still can not be fallen after backwash; passage I must shut down maintenance; then PLC control cabinet 400 able to programme sends signal and drives water inlet electric three-way ball valve 1 and water outlet electric three-way ball valve 6 switching states, switches to passage II and filters backwashing procedures.

Above-mentioned whole process all is automatic control, but also can regularly change.Automatic switchover passage I, passage II filter continuously, the sewage backwash function, guarantee that the on-line operation connecting technique supplies water, and improves the continuity of drainage and the efficient of drainage.
