Description
Technical field
The utility model relates to a kind of filter, particularly a kind of liquid filter with real-time self-cleaning function.
Background technology
Filter is a kind of widely used device that is used for decontaminating liquid, gas, utilizes it to filter out impurity in liquid or the gas, as the earth in the detected water sample, dust, coke tar particles etc. in the gas.Most of filters all adopt direct filtration means: allow liquid or gas all by the screen pack with certain pore size size in the filter, can be used for analyzing or using by liquid comparatively clean behind the screen pack or gas, impurity then is trapped within a side of described screen pack, thereby this filter stops up easily, need frequent dismounting filter to clear up screen pack, maintenance workload is big, and the service efficiency of filter is not high yet.
In order to solve the existing big technical problem of filter service workload, notification number is that the Chinese patent of CN2493650Y discloses a kind of filter rinsed of automatically exempting from, this filter has a rotatable filter screen that is driven by decelerator, fixing trumpet-shaped interface is arranged in filter screen, the outside of filter screen is provided with the dirty cutter of scraping of strip, described horn-like interface is corresponding with the press water rinse mouth, and with of filter screen between separate space corresponding.Working method is as follows: when usual the filtration, filter screen does not rotate, valve closing.Removing contamination during operating mode of setting, the blowdown motor-driven valve is opened, decelerator drives filter screen and rotates, strip is scraped dirty cutter and earlier the attachment of filter screen outer wall is struck off, when separate space between filter screen runs to rinse mouth, horn-like interface correspondence position, the flushing motor-driven valve is opened, the water under high pressure back flush filter screen of cleaning, thoroughly remove the remaining dirt that is attached on the filter screen clean, all dirts are discharged through the horn-like blowoff valve that is interfaced to, can realize differential pressure control by the differential pressure display, realize timing controlled, show operation manually by manual-operating mechanism by Programmable Logic Controller.This filter has been realized automatic cleaning function, but following deficiency is also arranged: 1) can not accomplish real-time cleaning, can not clean during filtration; 2) structure is complicated, also will be furnished with decelerator, scrape frame for movement and high pressure recoil water such as dirty cutter; 3) cost is higher, needs parts such as motor-driven valve, rotatable filter screen, decelerator.
The utility model content
In order to solve above shortcomings in the prior art, the utility model provides a kind of and can clean in real time, structure is simpler, lower-cost self-cleaning liquid filter.
For achieving the above object, the utility model is by the following technical solutions:
A kind of real-time self-cleaning liquid filter, described filter comprises urceolus, filter core and outlet; Described filter core is installed in the described urceolus, an end opening, other end sealing, and openend is connected with described outlet; Described urceolus is provided with import, and an end of described urceolus and outlet keep sealing, and the other end is provided with the waste discharge mouth; Flow by the waste discharge mouth is greater than the flow by outlet.
Described import is arranged on the top of urceolus, and the link of described outlet and filter core is lower than the position of described import.
The exit mounted valve of described urceolus.
Described filter core and outlet adopt welding or thread connecting mode.
On the described outlet connector is installed, described connector is connected with urceolus and keeps sealing.
The support member that is used to support filter core is installed on the described filter core.
According to the technical solution of the utility model, because liquid being filtered is when being filtered, wherein most liquid flows out by the waste discharge mouth place of urceolus, and this part liquid has washed away the outer surface of filter core in big flow ground when flowing between urceolus and filter core, avoided the impurity in the liquid to rest on the outer surface of filter core for a long time and then stopped up filter core, when really having realized filtering again self-cleaning the function of filter core; And the liquid of residue fraction is used for analyzing or using by being flowed out by outlet behind the filter element filtering.
Compared with prior art, the utlity model has following technique effect: 1) this self-cleaning liquid filter has been realized online real-time cleaning, has also cleaned filter core in the time of filtration, has prolonged maintenance period, has improved the service efficiency of analytical instrument; 2) simple in structure, need not motor-driven valve, parts such as rotatable filter screen, decelerator; 3) cost is lower, need not parts such as motor-driven valve, rotatable filter screen, decelerator.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is done further detailed description.
Embodiment 1:
As shown in Figure 1, a kind of real-time self-cleaning liquid filter is used for the impurity of filter liquide, comprises urceolus 1, filter core 2, outlet 3 and connector 7.
As shown in Figure 3, described filter core 2 is tubular filter screens, be installed in the described urceolus 1, and an end opening, end sealing, openend adopts welding manner to be connected with an end of described outlet 3; The inside of described filter core 2 is equipped with the support member (not shown), is used to support described filter core 2.The outer rim of described outlet 3 is welded with connector 7, and described connector 7 has internal thread.The other end of outlet 3 is filtrate (liquids 5.The top of described urceolus 1 sidewall is provided with inlet 4, the position of inlet 4 is higher than the link of described outlet 3 and filter core 2, one end of described urceolus 1 has external screw thread, the external screw thread on the described urceolus 1 and the screw-internal thread fit of connector 7, urceolus 1 is connected with described connector 7 and keep the sealing, the other end of urceolus 1 is provided with waste discharge mouth 6, and at described waste discharge mouth 6 place's mounted valves.
The course of work of above-mentioned real-time self-cleaning filter is: described self-cleaning filter is vertically installed, the liquid of certain flow enters from described inlet 4, as 30L/min, enter urceolus 1 interior backlash and hit outlet 3, and along described filter core 2 to dirty, the fluid flow of controlling waste discharge mouth 6 places that make urceolus 1 by valve is bigger, as 25L/min.Therefore, the liquid that enters in the urceolus 1 has only fraction to filter in the laggard inlet/outlet pipe 3 through described filter core 2, and flows out from described filtrate (liquid 5; And most liquid big flow ground when flowing downward has washed away the outer surface of described filter core 2, and from described waste discharge mouth 6 outflows, this part cleaning liquid the outer surface of described filter core 2, the outer surface of avoiding impurity in the liquid to rest on filter core 2 for a long time stops up filter core 2, when really having realized filtering again self-cleaning the function of filter core 2.
Embodiment 2:
As shown in Figure 2, a kind of real-time self-cleaning liquid filter is used for the impurity of filter liquide, comprises urceolus 1, filter core 2, outlet 3, connector and securing member 8.
