The specific embodiment
Below with reference to accompanying drawing, use following embodiment to be further elaborated the utility model.
As Figure 1-Figure 2, a kind of rotary backwash suction filter described in the present embodiment, comprises
Housing 1, forms cavity 2 in described housing 1, and one end of described cavity 2 is liquid sucting port 3, and the other end is liquid outlet 4;
Filter core 5, can be rotatably set in described cavity 2, and described cavity 2 is separated with described liquid outlet 4, and described liquid sucting port 3 communicates with described cavity 2, and the outlet of described filter core 5 communicates with described liquid outlet 4;
Block valve, is arranged on described liquid sucting port 3 places, controls the feed flow of liquid case to described liquid sucting port 3 places, and in the present embodiment, described block valve is preferably butterfly valve;
The sidewall of described housing 1 is provided with somely arranges along described filter core 5 length directions, and the backwash liquid spray-hole 7 communicating with described cavity 2, and the minimum sidewall in described housing 1 position is provided with backwash liquid outlet 8.
In the present embodiment, the two ends of described filter core 5 can be rotatably set on described housing 1 by bearing arrangement respectively.Described bearing arrangement is in the present embodiment: described filter core 5 forms the clutch shaft bearing hole that is applicable to installing clutch shaft bearing 11 on the end face of one end of described liquid sucting port, the position of the described outlet of the close described filter core 5 of described housing 1 forms the second dead eye that is applicable to installing the second bearing 12, described liquid sucting port place is also provided with logical liquid plug 13, on one end of described logical liquid plug 13, be formed with and make the liquid of described liquid sucting port toward some liquid-through holes 14 of described cavity 2 interior streams, the other end of described logical liquid plug 13 is formed with and is applicable to inserting the bolster in described clutch shaft bearing 11, the port of export of described filter core 5 is shaped to and is applicable to inserting the support column in described the second bearing 12.
The design of said structure makes rotary backwash suction filter of the present utility model possess under the prerequisite of rotary backwashing function realizing filter, and structure is more simple compact, and Operation and Maintenance is more convenient, and reliability is higher, and cost is lower.
Continual and steady in order to guarantee the high pressure backwash liquid feed flow in each backwash liquid spray-hole, on the lateral wall of described housing 1, be formed with the spray chamber 9 communicating with described backwash liquid spray-hole 7, described spray chamber 9 is provided with the recoil valve interface 10 being communicated with recoil valve.
Between the axis of described backwash liquid spray-hole 7 and excessively described filter core 5 axle center and the line of described backwash liquid spray-hole 7 outermost end points, be formed with an angle.This angle can be 30 °, also can be set to 60 ° in other embodiments, certainly in the present embodiment, this angle is preferably 45 °, and backwash liquid is sprayed onto on filter core 5 with 45 ° of angle directions, just in time can produce a power that makes filter core 5 rotations, and the two ends of filter core 5 are supported by two bearings respectively, when high-pressure spray liquid is flushed in its surface, filter core will rotate, thereby make covering the foul of cartridge surface, can clean up soon.
In order to realize the recycling of backwash liquid, described backwash liquid outlet 8 is communicated with the liquid filter that returns of described liquid case by drain outlet.
The course of work of rotary backwash suction filter of the present utility model:
During normal feed flow, butterfly valve 6 is opened, and recoil valve and backwash liquid outlet 8 are closed, and the liquid in liquid case enters filter core 5 through butterfly valve 6 by liquid sucting port 3, cavity 2, after filter core 5 filters, then from the imbibition chamber of the outlet supply pump of filter core 5.When needs clean filter core 5, to first stop the running of pump, close again after butterfly valve 6, recoil valve is opened, allow high pressure liquid enter the spray chamber 9 of filter housing, by backwash liquid spray-hole 7, be ejected on the surface of filter core, because jet is not by the axial line of filter, but with the direction at axial line angle at 45 °, therefore, produce a power that makes filter core 5 rotations, and the two ends of filter core 5 are supported by two bearings respectively, when high-pressure spray liquid is flushed in its surface, filter core will rotate, thereby make covering the foul of cartridge surface, can clean up soon, liquid after cleaning and the backwash liquid outlet 8 of the foul rinsing from below, through drain outlet, turning back to liquid case returns in liquid filter, reclaim.When rinsing suction filter, because this pump is to be in stopped status, the liquid suction valve of pump and the check valve in feather valve, all in closed condition, in the past the imbibition cavity direction of pump do not have liquid flow.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being extended out thus or change are still among the protection domain in the invention.
