Description
Technical field
The utility model is related to filter technology field, specially a kind of self-rotary negative pressure backwash fore filter.
Background technology
Fore filter can be formed by strainer filtering iron rust, silt and jelly after filtering for a long time in screen surface
Intractable attachment reduces water yield, cannot be fully erased by backwash, it is necessary to remove strainer using hairbrush and other items
Cleaning, time-consuming, laborious, dismounting repeatedly can also reduce leakproofness, and there are security risks.
Utility model content
The problem of for background technology, the utility model provide a kind of self-rotary negative pressure backwash prefilter
Device can effectively rinse out the intractable attachment for being attached to screen surface by the negative pressure plunger design added, without
Repeated disassembled and assembled is cleaned, time saving and energy saving.
To achieve the above object, the utility model provides following technical solution：A kind of self-rotary negative pressure backwashes preposition mistake
Filter, including housing, the housing upper end is connected with water inlet pipe, which is connected with blow-off pipe by backwashing handwheel,
Strainer and negative pressure plunger are provided in the filtrate chamber of the enclosure interior, the negative pressure plunger top is connected with strainer, should
Negative pressure plunger lower end is connected with blow-off pipe, and uith screw chamber, the negative pressure plunger and uith screw chamber are provided in the backwash handwheel
It is threadedly coupled.
As a kind of preferred technical solution of the utility model, the strainer is made of stainless steel.
As a kind of preferred technical solution of the utility model, the backwash handwheel outer wall is enclosed with Anti-slip cover.
As a kind of preferred technical solution of the utility model, the filter screen bottom is pyramidal structure.
Compared with prior art, the beneficial effects of the utility model are：The utility model is set by the negative pressure plunger added
Meter can effectively rinse out the intractable attachment for being attached to screen surface, be cleaned without repeated disassembled and assembled, time saving and energy saving, knot
Structure brief and practical, convenient for promoting.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Embodiment：
It please refers to Fig.1 and Fig. 2, the utility model provides a kind of self-rotary negative pressure backwash fore filter, including housing
1,1 upper end of housing is connected with water inlet pipe 2, which is connected with blow-off pipe 3, the housing by backwashing handwheel 7
Strainer 6 and negative pressure plunger 5 are provided in filtrate chamber 4 inside 1,5 top of negative pressure plunger is connected with strainer 6, this is negative
5 lower end of hydraulic plunger is connected with blow-off pipe 3, and uith screw chamber 8, the negative pressure plunger 5 and interior spiral shell are provided in the backwash handwheel 7
Chamber 8 is threadedly coupled.
Negative pressure plunger 5, the work of negative pressure plunger 5 are installed in the filtrate chamber 4 that the utility model passes through fore filter
Principle is similar to syringe, and by rotary back flushing handwheel 7, the position height that handwheel 7 is backwashed during rotation is solid
It is fixed constant, with the stopper rod of negative pressure plunger 5 that it is threadedly coupled be convenient for it is opposite move down, in this folding process
The negative pressure cavity of a part can be formed at 5 top of negative pressure plunger, backwash flow can collect shape rapidly into this negative pressure cavity
Flow is rotated clockwise into one, the backwash flow of rotation can effectively clean the attachment on 6 surface of strainer.
Specifically, the strainer 6 is made of stainless steel, preventing from getting rusty blocks the mesh of strainer 6.
Specifically, backwash 7 outer wall of handwheel is enclosed with Anti-slip cover 9, anti-skidding effect is played, convenient for backwashing handwheel
7 rotation.
Specifically, 6 bottom of strainer is pyramidal structure.
Based on above-mentioned, the utility model has the advantage that：The utility model designs energy by the negative pressure plunger added
It is enough effectively to rinse out the intractable attachment for being attached to screen surface, it is cleaned without repeated disassembled and assembled, time saving and energy saving, structure letter
Clean practicality, convenient for promoting.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
