Abstract
The utility model discloses a self-cleaning filter. The self-cleaning filter comprises a main filter tube and a side filter tube which is arranged in a manner of being inclined to the main filter tube, wherein the left end of the main filter tube is provided with a water inlet, and the right end of the main filter tube is provided with a water outlet; a filtering cavity is formed in the side filter tube; a filtering screen is arranged in the filtering cavity; a filtering screen fixing sealing seat is arranged at the tail end of the side filter tube; a valve is arranged in the filtering screen fixing sealing seat. The characteristics of a Y-type filter and a backwash filter are combined, and the self-cleaning filter is simple in structure, low in manufacturing cost and small in equipment volume. Compared with the Y-type filter which is wide in application, the self-cleaning filter has the advantage that the manual or automatic pollution discharge can be realized by additionally arranging a manual valve or an electric valve on an inner notch only.
Description
Technical field
The utility model relates to a kind of filter, is a kind of small-sized self-cleaning filter of cheapness specifically.
Background technology
Filter is indispensable a kind of device on the pumped (conveying) medium pipeline, usually is arranged on the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment, is used for eliminating the impurity in medium, with the normal use of protection valve and equipment.After fluid enters the filter cylinder that is equipped with the certain specification filter screen, its impurity is blocked, clean filtrate is discharged by filter outlet, when needs clean, as long as dismountable filter cylinder is taken out, reloads and get final product after processing, therefore, pipeline need to be closed while safeguarding, assemble again after then dismantling, clearing up.The equipment that not only affects is normally used, and safeguard cumbersome, not quick detachable or situation after death of rust.
Although backwash filter has on the market overcome the shortcoming of the maintenance inconvenience of conventional filter, it be the more important thing is and lack the following small-bore product of DN50 because complex structure own, manufacturing cost is high, maintenance cost is high, equipment volume is large.
Summary of the invention
The utility model purport, for overcoming the deficiencies in the prior art, provides a kind of self-cleaning filter.
To achieve these goals, according to the utility model by the following technical solutions:
A kind of self-cleaning filter, it comprises main chimney filter and the side chimney filter be obliquely installed with main chimney filter, main chimney filter left end is water inlet, right-hand member is delivery port, be provided with filter chamber in the side chimney filter, screen pack is installed in filter chamber, and the end of described side chimney filter is provided with screen pack fixing seal seat, in screen pack fixing seal seat, is provided with valve.
Described valve is hand-operated valve or motor-driven valve.
Be provided with internal sealing plug in described screen pack fixing seal seat, valve is connected with screen pack fixing seal seat by internal sealing plug.
Described main chimney filter inwall is provided with projection, and this projection this projection 10 that contacts with described screen pack has inclined-plane, impurity accumulation place of inclined-plane on screen pack 6.This projection plays and stops current, makes current scour be deposited in after filtration the effect of the impurity on screen pack.
Using method of the present utility model:
The utility model combines the characteristics of y-type filter and backwash filter, not only simple in structure, cheap for manufacturing cost, equipment volume is small and exquisite.With respect to using widely used y-type filter, only need on internal sealing plug, increase a hand-operated valve or motor-driven valve just can be realized blowdown manually or automatically.
Additional aspect of the present utility model and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present utility model.
The accompanying drawing explanation
Fig. 1 is the structural representation according to the self-cleaning filter of the utility model embodiment.
Wherein, 1. main chimney filter, 2. side chimney filter, 3. water inlet, 4. delivery port, 5. filter chamber, 6. screen pack, 7. screen pack fixing seal seat, 8. internal sealing plug, 9. impurity accumulation place, 10. projection.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Below with reference to Fig. 1, the self-cleaning filter according to the utility model embodiment is described.It comprises main chimney filter 1 and the side chimney filter 2 be obliquely installed with main chimney filter, and main chimney filter 1 left end is water inlet 3, and right-hand member is delivery port 4.Be provided with filter chamber 5 in side chimney filter 2, screen pack 6 is installed in filter chamber 5.The end of described side chimney filter 2 is provided with screen pack fixing seal seat 7, between screen pack fixing seal seat 7 and side chimney filter 2, is threaded connection.Be provided with internal sealing plug 8 in screen pack fixing seal seat 7, also be provided with the hand-operated valve (not shown), valve is connected with screen pack fixing seal seat 7 by internal sealing plug 8.
Described main chimney filter 1 inwall is provided with projection 10, and this projection 10 contacts with the upper end of described screen pack 6.This projection 10 has inclined-plane, impurity accumulation place of inclined-plane on screen pack 6.Projection 10 plays the effect that stops current, makes the alluviation power of current larger, and the direction that can make water impact can the self-cleaning filter be deposited in the impurity on screen pack for filtering impurity accumulation place 9 on meat 7.After opening hand-operated valve, the impurity under washing away is flowed out by valve, play the self-cleaning effect.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that do not break away from principle of the present utility model and aim can be carried out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
