Abstract
The utility model essentially discloses a kind of spiral-flow type self-cleaning filter, its technical solution: including cylinder, stainless steel filter core, flange, inlet, liquid outlet and sewage draining exit, the cylinder side connects inlet, connecting flange at the top of cylinder, liquid outlet is connected at the top of flange, the cylinder is up big and down small structure, hollow support pipe is connected with below the flange, it is connect on the downside of the hollow support pipe with stainless steel filter core, blowdown valve is equipped at the sewage draining exit, liquid is entered from inlet, after cylinder is hydraulically full, due to cylinder segmented different-diameter, the liquid or gas of filtering can rotate under the influence of centrifugal force after entering cylinder, the impurity of weight is at blowdown valve, light impurity can float up, partially liq is filtered through filtration core simultaneously, it is discharged from liquid outlet.Hollow support pipe had not only effectively avoided impact of the liquid to filter core, but also can play a supporting role to filter core, extended the service life of filter core.
Description
Technical field
The utility model relates to filter technology field, especially a kind of spiral-flow type self-cleaning filter.
Background technique
Self-cleaning filter is a kind of impurity directly intercepted in the liquid containing solid phase using strainer, and removal contains solid phase
Liquid suspension, particulate matter, reduce turbidity, purify the liquid matter containing solid phase, reduce system dirt, bacterium algae, corrosion etc. produce
It is raw, with the precision equipment for purifying the liquid matter containing solid phase and system other equipment being protected to work normally, the liquid containing solid phase
By entering self-cleaning filter body into the liquid port containing solid phase, filter cylinder is all integral structure at present, internal straight
Diameter size is the same, and cleaning effect is general, and filter core is directly impacted and can be had a certain impact.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of spiral-flow type self-cleaning filter, cylinder is utilized
Internal variable-diameter structure promotes liquid in rotation to form centrifugal force and effectively cleans filter core, prolonging service life of filter elements.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of spiral-flow type self-cleaning
Filter, including cylinder, stainless steel filter core, flange, inlet, liquid outlet and sewage draining exit, the cylinder side connect inlet, cylinder
Connecting flange at the top of body, flange top connect liquid outlet, and the cylinder is up big and down small structure, are connected with below the flange
Hollow support pipe, the hollow support pipe downside are connect with stainless steel filter core, and blowdown valve is equipped at the sewage draining exit.
The utility model is set between the large cylinder and small cylinder further, the cylinder includes large cylinder and small cylinder
First Transition portion is set, large cylinder bore is greater than small cylinder bore, and First Transition portion bore gradually becomes smaller from top to bottom, the small cylinder
Second transition part is set between body and blowdown valve, and the second transition part bore gradually becomes smaller from top to bottom.Filter cylinder segmentation
Formula different-diameter, liquid flows from top to bottom promotes liquid in rotation, forms centrifugal force, is pooled to impurity at liquid outlet, effectively
Cleaned filter core.
The utility model is further, the hollow support pipe is corresponding at inlet.Hollow support pipe was both effectively kept away
Exempt from impact of the liquid to filter core, and can play a supporting role to filter core, extends the service life of filter core.
The utility model is further, inlet uses pyramidal structure.
The utility model is further, stainless steel filter core bottom is closed, under stainless steel cartridge top and hollow support pipe
Side connection, and junction is equipped with sealing ring, sealing effect is good.
The utility model has the beneficial effect that
Liquid is entered from inlet, after cylinder is hydraulically full, due to cylinder segmented different-diameter, the liquid of filtering or
Person's gas can rotate under the influence of centrifugal force after entering cylinder, and at blowdown valve, light impurity can float the impurity of weight
It goes, while partially liq is filtered through filtration core, is discharged from liquid outlet.
Hollow support pipe had not only effectively avoided impact of the liquid to filter core, but also can play a supporting role to filter core, extended
The service life of filter core.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1.
Appended drawing reference: 1, cylinder；2, stainless steel filter core；3, flange；4, inlet；5, liquid outlet；6, sewage draining exit；7, blowdown
Valve；8, hollow support pipe；9, large cylinder；10, small cylinder；11, First Transition portion；12, the second transition part.
Specific embodiment
In conjunction with attached drawing, the utility model preferred embodiment is described in further details.
A kind of spiral-flow type self-cleaning filter as described in Fig. 1-2, including cylinder, stainless steel filter core 2, flange 3, inlet
4, liquid outlet 5 and sewage draining exit 6, blowdown valve 7 is equipped at the sewage draining exit 6, and 1 side of cylinder connects inlet 4, inlet 4
Using pyramidal structure, connecting flange 3 at the top of cylinder connects liquid outlet 5 at the top of flange 3, and the cylinder is up big and down small structure,
Cylinder described in the present embodiment includes large cylinder 9 and small cylinder 10, and First Transition is arranged between the large cylinder 9 and small cylinder 10
Portion 11,9 bore of large cylinder are greater than small 10 bore of cylinder, and 11 bore of First Transition portion gradually becomes smaller from top to bottom, the small cylinder
Second transition part 12 is set between 10 and blowdown valve 7, and 12 bore of the second transition part gradually becomes smaller from top to bottom.
Liquid is entered from inlet 4, after cylinder is hydraulically full, due to cylinder segmented different-diameter, the liquid of filtering
Or after gas enters cylinder, liquid will form rotation in cylinder inboard wall, and under the influence of centrifugal force, the impurity of weight is to down toward row
At dirty valve 7, to be filtered sewage draining exit 6 is opened after a certain period of time, and impurity is flowed out from sewage draining exit 6, and light impurity can float up, simultaneously
Partially liq is filtered through filtration core, and qualified liquid is discharged from liquid outlet 5.
Hollow support pipe 8,2 bottom of the stainless steel filter core closing are connected with below the flange 3, stainless steel filter core 2 pushes up
It being connected on the downside of portion and hollow support pipe 8, connection type can be socket and can also be threadedly coupled, and junction is equipped with sealing ring,
Sealing effect is good.The hollow support pipe 8 is corresponding at inlet 4, and hollow support pipe 8 had both effectively avoided liquid to filter
The impact of core, and can play a supporting role to filter core, extend the service life of filter core.
Above-described embodiment is only used for illustrating the inventive concept of the utility model, rather than to the utility model rights protection
Restriction, all non-essential modifications to the present invention made by this concept should all fall into the protection model of the utility model
It encloses.
