Description

The husky self-cleaning strainer of a kind of row
Technical field
The utility model belongs to industrial circulating water purification treatment technology field, relates in particular to the husky self-cleaning strainer of a kind of row.
Background technology
Industrial circulating water is carried out filtration device structure that in-line purification handles generally as shown in Figure 1, is existing industrial circulating water filter interior structural representation.Its operation principle is: former water is from water inlet 91 input coarse filtration chambeies 92, through coarse strainer 93 with former water in the bigger impurity interception of particle, enter fine filtering chamber 94 again, further filter the back water purification from delivery port 96 discharges through fie screen 95.After the regular hour filtration, the inwall of fie screen 95 tends to gather one deck impurity, at pressure reduction that progressively increases of fie screen 95 inside and outside generations, when this pressure reduction is excessive, will have influence on the normal rate of filtration, for this reason, central authorities are provided with dirt sucking device assembly 6 vertically in the cylindricality fine filtering chamber 94 that fie screen 95 surrounds, be arranged at intervals with a plurality of suction nozzles 61 on this dirt sucking device assembly 6, this dirt sucking device assembly 6 drives the shaft joint 9 that is connected on the screw rod 8 by rotary drive motor 7, when anti-cleaning is blowdown, electromagnetism blowoff valve 11 is opened automatically, this dirt sucking device assembly 6 is done the spiral translation to blowdown chamber 12 directions under the driving of rotary drive motor 7, cause suction nozzle 61 synchronous operations, electromagnetism blowoff valve 11 is opened, cause the hurried decline of pressure in blowdown chamber 12, blowdown chamber 12 is communicated with suction nozzle 61 with this soil pick-up assembly 6, thereby with respect to the synchronous hurried decline of the pressure in fine filtering chamber 94, thereby the comprehensive sucking that suction nozzle 61 is realized the impurity that is adsorbed on fie screen 95 inner wall surface, impurity arrives blowdown chamber 12 by soil pick-up assembly 6 and is discharged by electromagnetism blowoff valve 11, reaches the purpose of cleaning.In this backwash process, current can continue to flow, thereby can realize the operation of continuous and automation.
Self-cleaning strainer wants to realize above-mentioned functions, the device that in good time detection inside and outside differential pressure must be arranged, when this pressure reduction meets or exceeds preset threshold, the electronic control unit output signal of telecommunication, above-mentioned rotary drive motor 7 drives dirt sucking device assembly 6 and does the axial screw translation, electromagnetism blowoff valve 11 is opened, and dirt sucking device assembly 6 is started working; Inside and outside differential pressure progressively reduces subsequently, rotary drive motor 7 drives and correspondingly stops action after dirt sucking device assembly 6 resets in good time, electromagnetism blowoff valve 11 cuts out, in order to avoid influence normal recirculated water filter efficiency, moves when this pressure reduction increases to aforesaid threshold values next time again.Be the control device that 200510100534.2 Chinese patent discloses a kind of self-cleaning strainer as the patent No., this control device is provided with the pressure test device for detection of the fie screen inside and outside differential pressure of filter, and control drives the cleaning driver that the dirt sucking device assembly is done axially-movable when the fie screen inside and outside differential pressure meets or exceeds certain threshold value.
Another application number is the cleaning driver that 200810066637.5 Chinese patent application file also discloses a kind of self-cleaning mechanical type filter, comprise with the piston mandril of the axial interlock of dirt sucking device assembly and piston and, the back pressure chamber that walks abreast and arrange successively from inside to outside in the piston chamber outside, trigger chamber, drive chamber, the pressure release chamber, wherein, trigger chamber and drive chamber and separated by the rigid walls liquid sealing of an activity, when in rigid walls is triggering chamber, triggering signal being arranged, to driving the motion of chamber direction, the driving chamber is communicated with and pressure release with the pressure release chamber, makes piston actuated dirt sucking device assembly become axially-movable.
Yet, even add these automatic control equipments, existing self-cleaning strainer also must carry out former water precipitation process to a certain degree earlier when filtration treatment, the thing precipitation in big or the proportion particle dirt heavier than water removed and to carry out filtration treatment by the fie screen in the filter, and by suction nozzle fie screen is carried out soil pick-up; The suction that suction nozzle produces must produce according to the pressure of water system, when the diameter of the dirty foreign material of bulky grain during greater than the gap between suction nozzle and the fie screen, dirty foreign material then can not be discharged from the inside of filter, after using the long period, the fie screen inner surface can form certain deposit gradually, the filter efficiency that influences fie screen is stopped up fully until fie screen and is lost filtering function, and causes can't the formula of spinning advance motion and influence the soil pick-up function of suction nozzle, can not normally guarantee the stability of filtration system; For agricultural irrigation, geological conditions is comparatively complicated, and existing filter relative mass is heavier can only fixedly install, and is difficult to move according to different landform, influences the user demand of different geological conditions.
