Abstract
The utility model discloses a nozzle of inside filter core dust removal usefulness of environmental protection sweeper, including columniform nozzle body, the lower tip edges and corners department of nozzle body is provided with oblique chamfer, insidely is a cylindrical cavity along the orientation of its axis in, the equipartition has a plurality of air vents in the chamfer to one side, the air vent sets up in oblique chamfer surface and extends to cylindrical cavity, the utility model has the advantage of scientific and reasonable design, weld it on blowback pipe, high -pressure gas gets into the blowback pipe, then blows out and to diffusion all around from a plurality of air vents that cylindrical cavity and chamfer to one side set up, above high -pressure gas blows to the filter core in the environmental protection sweeper, increased to the filter core to blow scan long -pending, improved to sweep efficiency, accord with the principle that the air flows and learns, reduced the frequency that needs the manual cleaning filter core.
Description
Technical field
This utility model is related to hygiene apparatus field and in particular to a kind of environmental protection sweeper internal core dedusting
Nozzle.
Background technology
A hole is only opened although ensureing certain altitude above anti-blowpipe in traditional filter box of environmental protection sweeper, but
Blowing to the area only having very little above filter element, the only sub-fraction of the dust above filter element in environmental protection sweeper blown off,
Therefore the frequency of labor cleaning's filter element is quite big, have a strong impact on the work efficiency of environmental protection sweeper.
Content of the invention
The problem existing for above-mentioned prior art, this utility model provides a kind of environmental protection sweeper internal core dedusting
Nozzle, increases the area that gas purges filter element, improves the efficiency of purging filter element.
This utility model is to solve above-mentioned technical problem to adopt the following technical scheme that, a kind of spray of sweeper filter element dedusting
Mouth, including cylindrical nozzle body, the lower surface of described nozzle body and side surface intersection are provided with ramp down angle, internal edge
On the direction of its axis is a cylindrical cavity；Multiple passages, described passage setting are evenly equipped with described ramp down angle
In ramp down angle surface and extend to cylindrical cavity.
It is further preferred that described ramp down angle surface is in 30 ° 60 ° with the angle of the side surface of nozzle body.
It is further preferred that described passage is vertically installed in the surface at ramp down angle and extends to cylindrical cavity.
It is further preferred that described passage point centered on the axis of nozzle body, in the form of space annular array
It is arranged at the surface at ramp down angle and extend to cylindrical cavity.
Compared with prior art, the beneficial effects of the utility model are: this modular construction is simple, and design science rationally, is led to
Cross and this utility model is welded on anti-blowpipe, make gases at high pressure enter anti-blowpipe, then from cylindrical cavity and ramp down angle
Multiple passage blowouts of setting are simultaneously spread to surrounding, and gases at high pressure blow to above the filter element in environmental protection sweeper, and it is right to increase
The purging area of filter element, improves purging efficiency, meets the principle of air flow, decreases the frequency needing hand sweeping filter element
Rate.
Brief description
Fig. 1 is this utility model structural representation,
Fig. 2 is sectional view of the present utility model.
In figure: 1, nozzle body, 2, ramp down angle, 3, cylindrical cavity, 4, passage.
Specific embodiment
In conjunction with accompanying drawing describe in detail the technical solution of the utility model, a kind of nozzle of sweeper filter element dedusting, including
Cylindrical nozzle body 1, the lower surface of described nozzle body 1 and side surface intersection are provided with ramp down angle 2, and inside is along it
One cylindrical cavity 3 is provided with the direction of axis；Multiple passages 4, described passage 4 are evenly equipped with described ramp down angle 2
It is arranged at ramp down angle 2 surface and extend to cylindrical cavity 3.
This utility model is rational in infrastructure simple, in actual use, this utility model is welded to above anti-blowpipe,
Gases at high pressure pass through in anti-blowpipe flow nozzle body 1, and gases at high pressure pass through cylindrical cavity 3 and spray purging filter element to underface
While and spray from the passage 4 with certain drift angle, to filter element surrounding blow, described ramp down angle 2 surface can be with nozzle
The angle of the side surface of body 1 is in 30 ° -60 °, and passage 4 is vertically installed in the surface at ramp down angle 2, with the axis of nozzle body 1
Centered on point, the form in space annular array is arranged at the surface at ramp down angle 2 and extends to cylindrical cavity 3, more meets sky
The principle of flow of air, increases the purging area to filter element, improves purging efficiency, decrease and need hand sweeping filter element
Frequency.
Of the present utility model ultimate principle, principal character and advantage have been shown and described above, new without departing from this practicality
On the premise of type spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within requirement and protect
The scope of the present utility model of shield.
