Preferably, wherein, it is characterized in that, the angle that described access hole and the first pipeline are formed is 30 degree.
Preferably, wherein, described primary filter surfaces externally and internally carries out rust prevention by applying liquid material paint after preservative treatment, outside spray paint.
The utility model at least comprises following beneficial effect: 1, in the ordinary course of things, as long as open access hole dust catcher etc. can complete filtering net cleaning work, saving dismounting connector could this loaded down with trivial details step of repair of filter screen.2, adopt clamp connection part to be connected with pipeline by screen pack, the middle setting that is flexible coupling adopting rubber ring, is convenient for changing screen pack.
Part is embodied by explanation below by other advantage of the present utility model, target and feature, part also will by research and practice of the present utility model by those skilled in the art is understood.
Accompanying drawing explanation
Fig. 1 is the primary filter structure chart of air duct of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
Fig. 1 illustrates the primary filter of air duct of the present utility model, comprises screen pack 130, access hole 140 and clamp connection part 150.
Screen pack 130 material is GB235 mild steel, and it is made up of circular frame and screen pack, and the diameter of circular frame is identical with the junction diameter of second pipe 120 with the first pipeline 110; Screen pack is woven into grid by mutually perpendicular wire, and size of mesh opening is between 10 ~ 20mm, and the nearly step of size of mesh opening is preferably 15mm.After the air containing light refuse chip enters second pipe 120 from the first pipeline 110 by screen pack 130, the light refuse chip in air is filtered net 130 and intercepts in the first pipeline 110 side, and air then enters second pipe 120 by screen pack 130.
Access hole 140 and the first pipeline 110 and second pipe 120 are with the metallic conduit of material, and its one end is fixedly connected with the first pipeline 110 lower end, thus access hole 140 and the first pipeline 110 are formed overhaul path; The other end of described access hole 140 is provided with end cap 141, and its size and access hole 140 match; Described end cap 141 is circular, accompanies packing ring, and use bolt fixing seal between end cap 141 and access hole 140; Described access hole 140 is inclined at the first pipeline 110 towards ground surface end, and the angle of inclination formed with the first pipeline is 20-50 degree, and the nearly step in angle of inclination is preferably 30 degree.
Clamp connection part 150 comprises sealing rubber ring 151, clip 152 and clamping screw.The groove size of described sealing rubber ring 151 and the first pipeline 110 and second pipe 120 matches; Clip 152 is metal material annulus, and the inner circle diameter of clip 152 and the external diameter of the first pipeline 110, second pipe 120 and screen pack match; During work, be set in by 2 sealing rubber rings 151 in the groove of the first pipeline 110 and second pipe 120, clip 152 is buckled in outside, then uses bolted.Because its rubber seal and clip adopt distinctive sealable structural design, groove connector is made to have good sealing, and increasing with tube fluid pressure, the corresponding enhancing of its sealing.
In another embodiment, the primary filter surfaces externally and internally of described air duct carries out rust prevention by applying liquid material paint after preservative treatment, outside spray paint.
When primary filter is installed, first screen pack 130 is folded between the first pipeline 110 and second pipe 120, with 2 sealing rubber rings 151 sheathed enter the first pipeline 110 and second pipe 120 groove in, then to be tightened by bolts after junction clip 152 is buckled.The access hole 140 of the first pipeline 110 bottom carries out sealing locking with end cap 141.During work, after air containing light refuse chip enters second pipe 120 from the first pipeline 110 by screen pack 130, light refuse chip in air is filtered net 130 and intercepts in the first pipeline 110 side, and air then enters second pipe 120 by screen pack 130.After primary filter uses a period of time, need cleaned filter screen 130, open the end cap 141 of access hole 140, with the impurity under large suction dust catcher cleaning interception.
As mentioned above, the utility model at least comprises following beneficial effect: 1, in the ordinary course of things, as long as open access hole dust catcher etc. can complete filtering net cleaning work, saving dismounting connector could this loaded down with trivial details step of repair of filter screen.2, adopt clamp connection part to be connected with pipeline by screen pack, the middle setting that is flexible coupling adopting rubber ring, is convenient for changing screen pack.
Although embodiment of the present utility model is open as above, it is not restricted to listed in description and embodiment utilization.It can be applied to various applicable field of the present utility model completely.For those skilled in the art, can easily realize other amendment.Therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
