Description
Technical field
The utility model relates to centrifugal blower, particularly a kind of novel centrifugal blower that dewaters that removes sand.
Background technique
For the equipment needing forced ventilation, much ventilate with centrifugal blower.But the blower fan used that ventilates does not have and removes sand except water function; namely after sand grains or water enter blower fan; can only be delivered in the equipment needing to ventilate with blower fan; conventional fan as shown in Figure 1; it is made up of Blower Housing, impeller; the outlet air end of Blower Housing is provided with an exhaust outlet, after the grains of sand or water enter Blower Housing, can only be delivered to the equipment needing to ventilate from exhaust outlet along with Blower Housing.If equipment needs to remove the sand grains in ventilating gas or water, can only adopt and increase special water removal device of removing sand before the impeller entering centrifugal blower.And this equipment is after sand grains or water enter impeller, utilize centrifugal principle, the absorption principle of solid crash characteristics and water is removed it.Therefore do not need to increase special water removal device of removing sand.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides the novel centrifugal blower that dewaters that removes sand that a kind of structure is simple, water removal effect of removing sand is good and wind loss is little.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel centrifugal blower that dewaters that removes sand, it comprises Blower Housing and impeller, impeller is arranged in Blower Housing, described Blower Housing is made up of snail plate and spiral case side plate, be front with the flow direction of wind, Blower Housing front end is provided with an exhaust outlet, the rear end of described snail plate is bent upwards at least 90 degree and forms snail tongue, a part for impeller is positioned at snail tongue, described exhaust outlet is provided with a flow distribution plate, and the blowdown that flow distribution plate and snail plate form a narrower in width is stitched.
Described exhaust outlet place is provided with one for connecting the outlet(discharge) flange of ventilation equipment.
Described Blower Housing internal surface is coated with water wetted material or vibration-absorptive material.
Described Blower Housing outer surface is coated with a coating.
The utility model has the following advantages: blower fan of the present utility model is provided with snail tongue, and snail tongue is beneficial to sand grains or water reaches spiral case inwall by centrifugal force, strengthens removing sand and water removal effect of blower fan; Blower Housing inwall is smeared or installs hydrophilic, the material of absorbing, make sand grains arrive spiral case inwall rebound effect to reduce, sand grains arrives Blower Housing inwall and then moves along inwall, rainwater then flows along inwall after reaching Blower Housing inwall, then being flowed out by blowdown seam, the function of removing sand and dewatering is played; Blowdown seam is very narrow, when ensureing to remove sand and dewater, makes again the wind loss of blower fan little.
Accompanying drawing explanation
Fig. 1 is the structural representation of conventional fan;
Fig. 2 is structural representation of the present utility model;
In figure, 1-Blower Housing, 2-impeller, 3-snail plate, 4-spiral case side plate, 5-exhaust outlet, 6-snail tongue, 7-flow distribution plate, 8-blowdown is stitched, 9-outlet(discharge) flange, 10-coating.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 2, a kind of novel centrifugal blower that dewaters that removes sand, it comprises Blower Housing 1 and impeller 2, impeller 2 is arranged in Blower Housing 1, described Blower Housing 1 is made up of snail plate 3 and spiral case side plate 4, be front with the flow direction of wind, Blower Housing 1 front end is provided with an exhaust outlet 5, the rear end of described snail plate 3 is bent upwards at least 90 degree and forms snail tongue 6, a part for impeller 2 is positioned at snail tongue 6, be beneficial to sand grains or water reaches snail plate 3 inwall by centrifugal force, described exhaust outlet 5 is provided with a flow distribution plate 7, the blowdown that flow distribution plate 7 and snail plate 3 form a narrower in width stitches 8, rainwater and grit discharge blower fan along blowdown seam 8, because blowdown seam is very little, so make the wind loss of blower fan very little.
In the present embodiment, described exhaust outlet 5 place is provided with one for connecting the outlet(discharge) flange 9 of ventilation equipment, as exhaust outlet connects a ventilation duct by outlet(discharge) flange 9, can realize long distance delivery air quantity, and not make air quantity weaken.
In the present embodiment, described Blower Housing 1 internal surface is coated with water wetted material or vibration-absorptive material, make sand grains arrive Blower Housing 1 inwall rebound effect to reduce, sand grains moves along inwall after arriving Blower Housing 1 inwall, and rainwater flows along inwall after arriving Blower Housing 1 inwall.
In the present embodiment, described Blower Housing 1 outer surface is coated with a coating 10, and way layer 10 can be paint, is not corroded easily, goes for rugged environment for the protection of blower fan.
The utility model also can use with water removal device of removing sand jointly, increases the cleaning effect to gas.
Claims (4)
