Abstract
The utility model discloses a dust filtering fan. The dust filtering fan is characterized in that blades of a centrifugal fan are in the shape of backward inclined arc and streamline; a dust filtering net cover is sheathed on a supporting rack and is mutually connected with a front disc of impellers of the centrifugal fan through the supporting rack; an air sealing ring is arranged on the front disc of the impeller, and a net cover head cover which is made of light material is arranged on the top of the dust filtering net cover; the air sealing ring is a double-folding and double-sealing ring. The utility model is extensively used for removing dust in factories, and is particularly suitable for filtering fiber dust in textile mills.
Description
The utility model relates to a kind of dust filtering fan.
Patent No. ZL96229957.X discloses a kind of name and has been called " dust filtering fan ", it comprises a motor this dust filtering fan, this motor links to each other with a centrifugal blower by its output shaft, before the suction inlet of this centrifugal blower, be provided with a taper dust filter net cover, this taper dust filter net cover is coaxial with described centrifugal blower, be positioned in described dust filter net cover back and be provided with a sealing gland ring on the described centrifugal blower fan blade wheel shroud, one dust collector hood is enclosed within outside the described dust filter net cover and is fixedly connected on the spiral case of described centrifugal blower, on this dust collector hood, be provided with an air intake pipe, the mouth of pipe of this air intake pipe is aimed at described dust filter net cover, at this dust collector hood by being provided with a steady air flow on the side inwall of air intake pipe and stopping that the voltage stabilizing plate that dust returns the dust filter net cover is provided with a dust collecting box below this voltage stabilizing plate.
This dust filtering fan, because the Blade Design of described centrifugal blower is reasonable inadequately, make the smaller of static pressure that moving air produced and dynamic pressure, cause clean air and dirt stream to produce a small amount of mixed flow phenomenon sometimes, be single folding inclination taper because of described sealing gland ring again, its sealing is poor, influence clean air separates with the strictness of dirt stream, so ride quality is relatively poor.In addition, this dust filtering fan also exists shortcomings such as stability of motions difference and dust filter net cover rapid wear.
The purpose of this utility model is to overcome the above-mentioned shortcoming that existing dust filtering fan exists, provide a kind of simple in structure, volume is little, power consumptive province, filter dirt are effective, the dust filtering fan of long service life.
The purpose of this utility model is achieved in that this dust filtering fan, it comprises a motor, this motor links to each other with a centrifugal blower by its output shaft, before the suction inlet of this centrifugal blower, be provided with a taper dust filter net cover, this taper dust filter net cover is coaxial with described centrifugal blower, be positioned in described dust filter net cover back and be provided with a sealing gland ring on the described centrifugal blower fan blade wheel shroud, one dust collector hood is enclosed within outside the described dust filter net cover and is fixedly connected on the spiral case of described centrifugal blower, on this dust collector hood, be provided with an air intake pipe, the mouth of pipe of this air intake pipe is aimed at described dust filter net cover, be provided with a steady air flow and stop that dust returns the voltage stabilizing plate of dust filter net cover by on the side inwall of air intake pipe at this dust collector hood, be provided with a dust collecting box below this voltage stabilizing plate, the blade shape that it is characterized in that described centrifuge wind is that the hypsokinesis arc is streamlined;
The described taper dust filter net enclosure and links to each other with the impeller shroud of described centrifugal blower by this supporting frame on a supporting frame, is provided with a guard top cover that is made by lightweight material on the top of this taper dust filter net cover;
Described sealing gland ring is the two envelope of a two-fold shape.
Dust filtering fan described in the utility model, because it is streamlined that the blade shape of described centrifugal blower is made the hypsokinesis arc, increased the ratio of the static pressure that moving air produced, made clean air and dirt stream be difficult for producing mixed flow, alleviated the burden of described sealing gland ring with dynamic pressure; Because of described sealing gland ring being made the two envelope of two-fold shape, strengthen the sealability of this sealing gland ring again, guaranteed the isolation fully of clean air and dirt stream, prevented the generation of mixed flow phenomenon, prolonged its working life; Because described dust filter net cover is installed on the supporting frame, increased the fastness and the working life of this dust filter net cover again; The utility model also is provided with a filter screen top cover that is made of lightweight material on the top of this dust filter net cover, therefore prevented the generation of this dust filter net cover movement of the top, thereby has guaranteed the stability of this dust filter net cover motion.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
