Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the full-automatic high-precision filter of the utility model.
Detailed description of the invention
As shown in Figure 1, this filter is pressure vessel, centre is cylindrical, two is circular head, by motor 1, reductor 2, main shaft sealing device 23, backwash positioner 24, upper shell 20, upper blowdown connection 22, upper backwash blowoff valve 21, upper backwash dirt sucking tube 3, upper spacer 5, main shaft 8, filter core 6, central tube 19, middle cylinder 7, delivery port 18 on middle cylinder, lower clapboard 9, lower backwash dirt sucking tube 11, lower house 16, down blow adapter 14, lower backwash blowoff valve 15, water inlet 12 on lower house, the differential pressure controller interface 13 of influent side, the differential pressure controller interface 17 of water outlet side forms.Reductor 2 passes through the ring flange of himself and the ring flange flange connect that upper shell 20 welds, reductor 2 output shaft and main shaft 8 adopt key connecting, main shaft 8 and upper shell 20 are by main shaft sealing device 23 sealed attachment, upper shell 20, middle cylinder 7, lower house 16 adopts flange seal to connect, upper spacer 5, lower clapboard 9, middle cylinder 7, central tube 19 adopts the mode of ring flange to connect, upper backwash dirt sucking tube 3 and main shaft 8 key connecting, upper backwash dirt sucking tube 3 connects with upper blowdown connection 22 movable sealing, upper seal disc 4 on upper backwash dirt sucking tube 11 connects with upper spacer 5 movable sealing, filter core 6 is placed between upper spacer 5 and lower clapboard 9, with upper spacer 5 and lower clapboard 9 for spigot-and-socket fixing seal connects, and circumferentially formula distribution, lower backwash dirt sucking tube 11 and main shaft 8 key connecting, lower backwash dirt sucking tube 11 connects with the movable sealing of down blow adapter 14 spigot-and-socket, lower seal dish 10 on lower backwash dirt sucking tube 11 connects with lower clapboard 9 movable sealing.
In order to can effectively the impurity of filter core 6 inner upper end be discharged, at upper backwash dirt sucking tube 3, seal disc 4 is housed, seal disc 4 is one large one small cylinder, the inner opened round through hole of cylinder, and be connected with upper backwash dirt sucking tube 3 sliding sleeve by manhole, the object that sliding sleeve connects be ensure upper seal disc 4 can well and upper spacer 5 fit tightly.
In order to can effectively the impurity of filter core 6 interior lower end be discharged, at lower backwash dirt sucking tube 11, lower seal dish 10 is housed, lower seal dish 10 is one large one small cylinder, the inner opened round through hole of cylinder, and be connected with lower backwash dirt sucking tube 11 sliding sleeve by manhole, the object that sliding sleeve connects be ensure lower seal dish 10 can well and lower clapboard 9 fit tightly.
Filter is when backwash, require the sealing of filter core 6 two ends, and require that former water does not enter in filter core 6, filter core 6 is oppositely poured in water outlet after filtration, in order to ensure above-mentioned requirements, upper backwash dirt sucking tube 3, lower backwash dirt sucking tube 11 and main shaft 8 key connecting, and make upper backwash dirt sucking tube 3 and lower backwash dirt sucking tube 11 at grade by main shaft.
Filter is in the process of filtering, a lot of situation there will be impurity that density is less than water and concentrates on filter core 6 middle and upper part in filter, the impurity that density is greater than water concentrates on the middle and lower part of filter inner filter core 6, arrange outside effectively that these are assorted, filter top and bottom are provided with backwash blowoff valve 21 and lower backwash blowoff valve 15 simultaneously, upper backwash blowoff valve 21 is communicated with upper backwash dirt sucking tube 3 by upper blowdown connection 22, and lower backwash blowoff valve 15 is communicated with lower backwash dirt sucking tube 11 by down blow adapter 14..
In order to better the present embodiment is described, below its operation principle is described in detail as follows:
During normal filtration, with pressurely treat that drainage enters lower house from water inlet, major part enters filter element filtering after drainage is by the distribution of lower clapboard, remaining part enters upper shell after drainage is by central tube, then filter element filtering is entered by the distribution of upper spacer, qualified water after filtration enters middle cylinder, flow out finally by the delivery port on middle cylinder, along with the carrying out of filtering, impurity in filter core progressively increases, the resistance filtered strengthens gradually, when reaching setting value, control system can send instruction, carry out the cleaning of filter core, now fill upper backwash blowoff valve on the filter and lower backwash blowoff valve is opened, motor via reducer drives main axis simultaneously, main shaft drives upper backwash dirt sucking tube to rotate together with lower backwash dirt sucking tube, when control system receives the position signalling that backwash positioner sends, motor is out of service, now, on, certain the filter core both ends open be contained on upper lower clapboard just in time seals by the seal disc on lower backwash dirt sucking tube, after filter core both ends open seals, filter core inside is directly communicated with air by blowoff valve, after filter core inside is communicated with air, its pressure is normal pressure, after that filter with pressure, fast of water oppositely pours filter core inside, filter core is cleaned, the impurity that density is less is discharged from upper backwash blowoff valve, the impurity that density is larger is discharged from lower backwash blowoff valve, after this filter element cleaning completes, motor reruns, same method, next filter core is cleaned, until all filter element cleanings complete, backwash terminates.Owing to there being multiple filter core in filter, when one of them filter core is in backwash, other filter core is in normal filtration condition, so filter is when backwash, whole filter is also in normal filtration condition, thus realizes online automatic cleaning.
