Abstract

The utility model discloses a pipeline filter comprising a shell, wherein the middle part of the top end of the shell is provided with a rack; a speed reducer is fixed on the rack and is connected with a stirring shaft through a shaft coupling; the top end of the shell is also provided with an access hole; the middle part of the shell is provided with a water inlet and a water outlet which are both connected with a filter cartridge; the filter cartridge is provided with more than two filter pipes, and the bottom ends of the filter pipes are connected with drainage pipes. According to the utility model, a filter screen is replaced with the stainless steel wedged filter pipes, gaps at the water inlet ends of the wedged filter pipes are relatively small, and gaps at the water outlet ends of the wedged filter pipes are relatively large, so that the defect that the filter screen is blocked is well overcome; meanwhile, the traditional large-diameter filter cartridge is changed into multi-column filter pipe distribution, so that the defect that the filter cartridge is easy to deform is well overcome.

Description

A kind of piping filter

Technical field

The utility model relates to a kind of filter, is specifically related to a kind of piping filter.

Background technology

Full-automatic filter is called again Full-automatic self-cleaning filter, backwash filter, automatic dirt-removing filtering device on market, and full-automatic filter discrete and horizontal two kinds are divided into by type of drive: pneumatic and hydraulic-driven; Full-automatic differential pressure formula Jenag strainer is roughly divided into two kinds by function, I and II type.

Filter medium is entered by filter cylinder inner side, after multiple filtration, solid suspension in liquid is trapped within filter cylinder inwall, because increasing gradually, dirt causes the poor increase of filter inlet and outlet pressure, Full-automatic self-cleaning filter is in the time that pressure reduction reaches setting value (0.01-0.10Mpa), blowdown suction nozzle goes to a certain filter cylinder below, blowoff valve is opened simultaneously, cause the pressure in this filter cylinder sharply to decline, now filter cylinder inside and outside differential pressure increases rapidly, the outer water purification of cylinder carries out powerful backwash to this filter cylinder, moment can thoroughly clean up dirt in filter cylinder, then blowdown mouth goes to next filter cylinder and carries out backwash, until each filter cylinder all cleans up, Full-automatic self-cleaning filter pressure reduction returns to set condition.

Utility model content

The utility model object is to provide a kind of simple in structure, and the piping filter of good filtration effect is also realized the interception of impurity simultaneously by the gap of screen pipe is set, and reaches the object that purifies former water.

Scheme of the present utility model is as follows: a kind of piping filter, comprise housing, housing top middle portion arranges frame, decelerator is fixed in frame, decelerator be connected with shaft by shaft coupling; Described housing top is also provided with access hole; Housing middle part is provided with water inlet, delivery port, and described water inlet, delivery port are connected with cartridge filter; More than two screen pipe is set on described cartridge filter, and described screen pipe bottom is connected with blow-off pipe.

Further, described screen pipe is stainless steel wedge shape chimney filter.

Further, described frame side is provided with single port exhaust-valve.

Further, described water inlet lower end is connected with differential pressure controller, and differential pressure controller is connected with y-type filter.

Further, described housing bottom arranges access hole II.

Further, on described blow-off pipe, be provided with hand-operated valve and electric butterfly valve.

The utility model replaces filter screen by design stainless steel wedge shape chimney filter, and wedge shape chimney filter water inlet end gap is little, and gap, water side is large, has well solved the defect of filter net jam; Traditional major diameter filter cylinder is changed into polystyle chimney filter simultaneously and distribute, well solved filter cylinder and held yielding defect.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of piping filter, comprises housing 1, and housing 1 top middle portion arranges frame 2, and decelerator 3 is fixed in frame 2, decelerator 3 be connected with shaft 5 by shaft coupling 4; Described housing 1 top is also provided with access hole 6; Housing 1 middle part is provided with water inlet 7, delivery port 8, and described water inlet 7, delivery port 8 are connected with cartridge filter 9; More than two screen pipe 10 is set on described cartridge filter, and described screen pipe 10 bottoms are connected with blow-off pipe 11.

Described screen pipe 10 is stainless steel wedge shape chimney filter; Described frame 2 sides are provided with single port exhaust-valve 12; Described water inlet 7 lower ends are connected with differential pressure controller 13, and differential pressure controller 13 is connected with y-type filter 14; Described housing 1 bottom arranges access hole II 15; On described blow-off pipe 11, be provided with hand-operated valve 16 and electric butterfly valve 17.

Although above detailed description of the invention of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that description contains yet, all should be within protection domain of the present utility model.
