Abstract

The utility model discloses a dust filtering fan. The dust filtering fan comprises an electric motor, a centrifugal fan and a tapered dust filtering net cover which is arranged at the front of a suction port of the centrifugal fan. The electric motor, the centrifugal fan and the dust filtering net cover are coaxially rotated; the connection portion of the dust filtering net cover and the centrifugal fan is provided with an air sealing ring; a dust collecting box is sheathed at the outside of the dust filtering net cover and is fixed on the volute shell of the centrifugal fan; an air inlet pipe is arranged on the dust collecting box, and a voltage stabilization plate is arranged at the inside wall of the dust collecting box of one side of the air inlet pipe and is positioned at the lower part of the dust filtering net cover. The utility model is extensively suitable for the dust removal of factories, and particularly suitable for filtering fiber dust of textile mills.

Description

Dust filtering fan

The utility model relates to a kind of dust filtering fan.

The cleaner that is used for factory at present, the equipment that is used in particular for filter fiber dust on the plant equipment such as scutching cotton, comb and parallel cotton fibers prior to spinning, combing, spun yarn of spinnery mainly contains two classes: a class is to be provided with the huge cleaner of a cover before ventilation blower, it falls dust separation earlier, the air that comparatively cleans is discharged by blower fan, the major defect of this type of cleaner is a complex structure, volume is big, takes; The structure of another kind of cleaner is to establish the huge dust filtration equipment of a cover behind a dedusting fan, the impeller of described dedusting fan is the straight leaf formula impeller of no shroud, after dust and air entered blower fan simultaneously, blade wore and tore easily, and this dedusting fan efficient is very low.

The purpose of this utility model be to provide a kind of simple in structure, volume is little, the power consumptive province, the dust filtering fan of good dedusting effect.

This dust filtering fan, it comprises a motor, this motor links to each other with a centrifugal blower by its output shaft, it is characterized in that before the suction inlet of described centrifugal blower, being provided with a taper dirt filtrating screen cover, this taper dirt filtrating screen cover is coaxial with described centrifugal blower, and link to each other with the impeller shroud of this centrifugal blower, on described dirt filtrating screen cover and described impeller shroud junction, be provided with a sealing gland ring, one disposal box, it is outer and be fixedly connected on the volute of described centrifugal blower to be enclosed within described dirt filtrating screen cover, on this disposal box, be provided with a blast pipe, the mouth of pipe of this blast pipe is aimed at described dirt filtrating screen cover, on the side inwall of this disposal box blast pipe and be positioned at described dirt filtrating screen cover below be provided with the voltage stabilizing plate of a steady air flow.

Dust filtering fan described in the utility model is to utilize taper dirt filtrating screen cover and blower fan to be combined into one and the synchronous high-speed revolution, dust is by taper dirt filtrating screen shelves that cover hinders, thereby and be subjected to fly away under the influence of taper dirt filtrating screen cover high speed rotary air-flow and the action of centrifugal force bottom that to the inwall of disposal box tenesmus enters disposal box, air then can see through the dirt filtrating screen cover and be sucked by blower fan and pure air is discharged; Dust filtering fan described in the utility model also utilizes the sealing gland ring effectively clean gas flow and dirt stream to be isolated, thereby reaches the purpose of clean gas flow and dirt stream non-interference; The utility model also utilizes voltage stabilizing plate steady air flow to flow, and stops that the dust that stockpiles in the disposal box bottom returns the dirt filtrating screen cover, thereby improves dust removing effects, therefore the utlity model has simple in structure, volume is little, the power consumptive province, advantages such as good dedusting effect.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of dust filtering fan described in the utility model.

Describe structure in detail below in conjunction with Fig. 1 according to the concrete dust filtering fan that the utility model proposes.

This dust filtering fan, it comprises a motor 1, this motor 1 links to each other with a centrifugal blower 2 by its output shaft, before the suction inlet of described centrifugal blower 2, be provided with a taper dirt filtrating screen cover 3, this taper dirt filtrating screen cover 3 is coaxial with described centrifugal blower 2, and be connected with the impeller shroud of this centrifugal blower 2, on the junction of described dirt filtrating screen cover 3 and described impeller shroud, be provided with a sealing gland ring 4, one disposal box 5 is enclosed within outside the described dirt filtrating screen cover 3 and is fixedly connected on the volute 8 of described centrifugal blower, on this disposal box 5, be provided with a blast pipe 7, the mouth of pipe of this blast pipe is aimed at described dirt filtrating screen cover 3, on the side inwall of these disposal box 5 blast pipes 7 and be positioned at described dirt filtrating screen cover 3 below be provided with the voltage stabilizing plate 6 of a steady air flow, the perisporium of described sealing gland ring 4 is taper seats, described voltage stabilizing plate 6 is circular-arc, and the end of this voltage stabilizing plate 6 is upturned.

The utility model is widely used in factory's dedusting, and it is specially adapted to the usefulness of filter fiber dust on the plant equipment such as scutching cotton, comb and parallel cotton fibers prior to spinning, combing, spun yarn of spinnery.
