Abstract
The utility model relates to a cyclone duster which comprises a cyclone external cylinder body (4), a pipe joint (2), an inner cylinder body (6), an air outlet channel (1), wherein, the cylinder wall of the inner cylinder body (6) is distributed with a plurality of vent holes; the vent holes (7) cause the inner cavity of the inner cylinder body (6) to be communicated with the inner cavity of the cyclone external cylinder body (4). The utility model is characterized in that a filter layer (5) used for filtering dust and venting covers the outer surface of the inner cylinder body (6); the filter layer (5) shields the vent holes (7). Because the outer surface of the filter layer is arranged in the inner cavity of the cyclone external cylinder body, rotary airflow with high speed causes tiny dust granules are not easy to adhere to the filter layer and the air permeability of the filter layer can be kept good for a long time.
Description
The utility model relates to a kind of rotoclone collector.
In the prior art, Britain Notetry Ltd took the lead in developing the dust-separating appliance that utilizes the centrifugal mechanism of swirling eddy in 1996, it is based on a common physical principle: make object make circular motion with certain acceleration (a), the external force (F) that adds thereon is directly proportional with its quality (m), i.e. F=ma; After external force did not exist, object tendency to drift away in the high speed rotary course that quality is big was also big.Therefore, if make the air-flow that has dust with certain rotating at a high speed, then dust granule can be separated from air greatly because of its quality.The product of Britain Notetry Ltd as shown in Figure 4, interface tube is by air-flow bend and Whirlwind barrel intracavity inter-connection, the outside inwall of its air-flow bend and the inwall of Whirlwind barrel are tangent, make most of air-flow enter cylinder lumen by the inwall tangential direction of Whirlwind barrel.Dust can be separated from air and be attached on the internal chamber wall of whirlwind outer cylinder body fully in theory, and the air-flow of discharging from inner barrel is a clean gas flow.But in fact reach the high-speed of theory surely, so some dust still can enter inner barrel and outside the air-out passage is discharged dust catcher, make the dust removing effects of dust catcher greatly reduce because the speed of the swirling eddy of input differs.In order to address this problem, it is that cross-wise direction at the air-out passage of inner barrel is provided with a filter dirt film that a kind of design is arranged, the frequent micropore of filtering on the dirt film that makes is stopped up by dust but the sectional area of this filter dirt film is little, has influenced the air draft of dust catcher, and the filter dirt film that should locate is changed difficulty.Second kind of design is that inner barrel is directly made with the filtering material of a duricrust, the convex tendon that this inner barrel outer surface is provided with a plurality of radial protrusions and extends vertically, the purpose of this convex tendon is the external surface area that increases inner barrel, to prolong the working time of dust suction, but this convex tendon influences the air-flow rotation in the whirlwind outer cylinder body inner chamber, and the low-lying place of dust accretions between convex tendon makes this locate basic stuffiness, in fact Tong Qi effective external surface area is in use more and more littler on the contrary, and it is bad to cause filtering the dirt effect.When filtering material is clogged by micronic dust and is difficult to clean, this inner barrel will need to change, and causing more, the cost of conversion materials improves.
The purpose of this utility model is to provide a kind of effective rotoclone collector of dirt of filtering.
The technical solution of the utility model is: a kind of Cyclonic dust collector, the whirlwind outer cylinder body that comprises next the end sealing of dust suction state, the interface tube that is used for the air-flow input with the intracavity inter-connection of described whirlwind outer cylinder body, be arranged in the inner chamber of described whirlwind outer cylinder body and with the coaxial inner barrel of described whirlwind outer cylinder body, the air-out passage that is used for air-flow output with the intracavity inter-connection of described inner barrel, be distributed with a plurality of passages on the barrel of described inner barrel, this passage makes the inner chamber of described inner barrel and the intracavity inter-connection of described whirlwind outer cylinder body, the outer surface of described inner barrel is covered with and is used to filter dirt and ventilative filter course, and this filter course has hidden described passage.
The utility model compared with prior art has following advantage:
Owing to be attached with filter course on the outer wall of inner barrel, therefore the part dust can be filtered layer filtration before entering inner barrel, make that the air-flow that enters inner barrel through passage is a clean gas flow, and the external surface area of inner barrel is big, makes described filter course to use the longer time and does not need to change.Particularly the filter course outer surface is arranged in whirlwind outer cylinder body inner chamber, and the air-flow of rotation makes that small dust granules is difficult for can making the permeability of filter course keep good in a long time attached on the filter course at a high speed.This position is used or replacing after making described filter course be easy to pull down washing again.
