Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in detail by embodiment.
As shown in Figure 1, 2, a kind of reverse-flow type boiler dust remover, including housing 1, the upper end of housing 1 connects upper cover, under
End connection has low head, and the lower end of low head connects dust collecting opening 7；Circular air inlet 2 it is provided with, in housing 1 on the top of housing 1
Portion is axially arranged with interior coil 9, and interior coil 9 extends upwardly to housing 1 outer formation air vent 11；In being provided with inside described housing 1
Entreating the dividing plate 10 passed with circular hole for interior coil 9, housing 1 is divided into upper and lower two cavitys by dividing plate 10；In in lower chamber
Coil 9 bottom is provided with the kuppe 4 of cylindrical shape, and the upper edge of kuppe 4 is less than the lower edge of air inlet 2, described dividing plate 10 and water conservancy diversion
It is provided with isocon 3 between cover 4；It is provided with baffle plate 5 in the bottom of described lower chamber, between baffle plate 5 outer rim and housing 1 inwall, leaves one
Fixed space, baffle plate 5 center has circular hole, and baffle plate 5 connects downwards dust leg 6；It is provided with epicoele in the outside of described housing 1
The return duct 8 being connected with dust leg 6 that body turns on lower chamber, the upper end of return duct 8 is connected to the lower end of upper cavity, with every
Plate 10 minimum point flushes.
Dividing plate 10 is the plectane tilted, and the height of plectane minimum point is identical with the height of air inlet 2 upper edge；Dividing plate 10 is oblique
Face is 22 ~ 26 ° with the angle of horizontal plane.
Being provided with arcuate groove on interior coil 9 in described upper cavity, the height of arcuate groove is 18～22 millimeters；Arc length is 30
～50 millimeters.
Realize the gas of air inlet 2 to the distance of air inlet 2 by controlling the internal diameter of isocon 3 or isocon 3 outer wall
Tangent with the cylindrical outer wall of the 1/2 of isocon 3.Described isocon is ceramic material.
Described upper cover is oval, and low head is taper；The bottom of interior coil 9 is bell-mouth structure of air, and baffle plate 5 is V-arrangement
