The specific working process is as follows: when the dust removing equipment designed by the utility model is used, when air passes through the air suction pipe orifice on the dust removing equipment, the air is sucked into the air suction pipe 2 under the suction force of the inlet booster fan 7, the air can bring the particle dust in the air into the air simultaneously when being sucked, the air entering the air suction pipe 2 enters the spiral filter pipe 4 along the air suction pipe 2, and the air entering the spiral filter pipe 4 flows downwards along the spiral filter pipe 4; during the downward air flow, because the spiral filter tube 4 is spiral, the particulate dust in the air will be subjected to a certain centrifugal force while flowing downward, under the action of the centrifugal force, as shown in a in fig. 19, a part of the heavier particulate dust will stick to the tube wall of the spiral filter tube 4 located at the upper side and move downward along the tube wall of the spiral filter tube 4, and when the part of the particulate dust reaches one of the two filter outlets 22 opened on the spiral filter tube 4 and located at the upper side 22 during the movement, the heavier particulate dust will flow into the corresponding fixed casing 24 through the corresponding filter outlet 22 and the corresponding collecting inlet 27 opened on the fixed casing 24 along the tube wall of the spiral filter tube 4, and when the part of the particulate dust flows into the fixed casing 24, a part of the air will flow into the fixed casing 24 together, but because the resistance of the air flow in the fixed casing 24 is large, the air flowing into the fixed casing 24 is relatively small, and the air filtered by the second inclined plate 28 in the corresponding fixed casing 24 and the first inclined plate 26 in the corresponding collecting casing 25 flows into the spiral filter pipe 4 through the corresponding air inlet passage 23 to continue flowing downwards, while the particulate dust entering the corresponding fixed casing 24 is retained in the corresponding collecting casing 25; at the same time, the air that does not flow into the upper fixed shell 24 continues to flow downwards along the spiral filter tube 4, as shown in b of fig. 19, because the cross-sectional area of the middle portion of the spiral filter tube 4 is smaller than that of the upper portion, the flow velocity of the air flowing into the middle spiral filter tube 4 is relatively increased without a small reduction of the air flow, the spiral diameter of the spiral filter tube 4 is relatively reduced, the centrifugal force to which the dust particles with reduced spiral diameter are subjected is relatively increased, and the centrifugal force to which the dust particles in the air are subjected is relatively increased, in this case, a part of the dust particles in the air are attached to the wall of the middle spiral filter tube 4 under the action of the centrifugal force and move downwards along the wall of the spiral filter tube 4, and when the part of the dust particles reaches one of the two filter outlets 22 opened on the spiral filter tube 4, which is located at the lower side, during the movement 22, the particulate dust will flow into the corresponding fixed casing 24 through the corresponding filtering outlet 22 and the corresponding collecting inlet 27 formed on the fixed casing 24 along the wall of the spiral filtering pipe 4, and simultaneously a part of air will flow into the fixed casing 24, the part of air filtered by the second inclined plate 28 in the corresponding fixed casing 24 and the first inclined plate 26 in the corresponding collecting casing 25 will flow into the spiral filtering pipe 4 through the corresponding air inlet channel 23 and continue flowing downwards, and the part of particulate dust entering the corresponding fixed casing 24 will remain in the corresponding collecting casing 25; the air which flows into the spiral filter pipe 4 is filtered twice, and the air which is filtered twice flows into the exhaust pipe 3 through the connecting pipe 21 and the corrugated pipe 17 and is exhausted to the indoor through the exhaust pipe 3.

In summary, the following steps: the utility model discloses a dust collecting equipment has designed two collection device 16 on spiral filter tube 4 for the air that flows into spiral filter tube 4 filters twice in different degree, filters the granule dirt of different size in the air in spiral filter tube 4 step by step, finally flows into blast pipe 3 through connecting pipe 21 and bellows 17 with the air that filters twice, then discharges to indoor, and the dust removal effect of this equipment is good; the utility model relates to a dust removing equipment, when the air gets into corresponding set casing 24 and collects in the shell 25, because the air flow resistance in set casing 24 and the collection shell 25 is great, under this state, the air that gets into in corresponding set casing 24 and the collection shell 25 will appear the random flow state, and the utility model discloses in prevent that the air random flow from blowing up the granule dirt that flows into in collection shell 25 and set casing 24 through first swash plate 26 and second swash plate 28, return to spiral filter tube 4 in from the collection entry 27 and the inlet channel 23 that open on set casing 24 once more, influence the filtration of spiral filter tube 4; the utility model relates to a dust collecting equipment, the first division board 29, the second division board 30 and the inlet channel 23 that design in this equipment play the water conservancy diversion effect for the air that flows into in the set casing 24 and the collection shell 25 for this part of air flows back to the spiral filter tube 4 through the inlet channel 23 in, reduce the air flow resistance in the set casing 24 and the collection shell 25 because of sealing causes, guarantee that some air current can get into and bring into some granules; the dust removing equipment designed by the utility model can control the pitch change of the spiral filter pipe 4 by controlling the lower end of the spiral filter pipe 4 to move up and down; when the screw pitch is relatively small, the curvature of the spiral filter pipe 4 is relatively large, the centrifugal force applied to the particle dust is relatively large, the number of particles capable of being filtered is relatively large, the dust removal effect is relatively good, but the air flow is relatively small due to the large resistance; when the screw pitch is relatively large, the curvature of the spiral filter pipe 4 is relatively small, the centrifugal force applied to the particle dust is relatively small, the particles capable of being filtered are relatively few, the dust removal effect is relatively poor, but the air flow is relatively large due to relatively small resistance; the device has the dust removal capacity and the function of adjusting the air flow; the control of the regulating motor 5 enables a user to better systematically regulate the dust removal effect and the dust removal flow during operation.
