Specific implementation mode
With reference to embodiment, the invention will be further described, but not as a limitation of the invention.
Please refer to figs. 1 to 4, the present embodiment is related to cyclone it is same as the prior art be same include three Divide Whirlwind cyclone 1, spiral guide vane 2 and gas-guide tube 3, but spiral guide vane 2 is fixedly connected with 1 phase of Whirlwind cyclone, it is non-dismountable.Whirlwind cyclone 1 is the cylinder of one section of upper and lower opening, and cylinder includes a direct tube section 4 and a up big and down small truncted cone section 5, frustum of a cone Section 5 is connected to the lower end of direct tube section 4.Several spiral guide vanes 2, spiral is equally spacedly distributed in inner wall at the top of direct tube section 4 The quantity of guide vane 2 can be used 6 by the conventional amounts of the prior art, can not also be waited with the conventional amounts of the prior art and use 6 More than piece, it is considered that quantity is no more than 10.Since spiral guide vane 2 itself will occupy one of 1 area of section of Whirlwind cyclone Point, excessive spiral guide vane 2 will reduce the negotiable section of air-flow, while the too small whirlwind that is also unfavorable in single gas channel section removes Dirt.The boundary line of spiral guide vane 2 and cylinder is circular helix, and the vertical height H of monolithic spiral guide vane 2 is external spiral diameter D That is the circular helix inclination angle of 1~1.2 times of cylinder internal diameter, spiral guide vane 2 is 35 °~40 °, which makes list Piece spiral guide vane 2 has enough length in its vertical height H so that high-speed flow can lead in spiral guide vane 2 and flow downward Enough time achievees the purpose that air-flow plays rotation separation.It is that the blade of equal in width is different from spiral guide vane 2 in the prior art, this implementation The spiral guide vane 2 of monolithic includes that wide section 6 and transition 7 wide at the top and narrow at the bottom, transition 7 are connected to wide section 6 of lower end in example, 8 position of tie point of wide section 6 and transition 7 is the lower end of transition 7 at the 1/3~1/2 of the vertical height H of spiral guide vane 2 Width W1 is less than or equal to the 1/2 of wide section of 6 width W2.The side of transition 7 is fixedly connected with the inner wall of cylinder, that is to say, that spiral shell Revolve guide vane 2 transition 7 be to narrow from inside to outside, the inside edge of spiral guide vane 2 constitute be flared downwards it is horn-like.In order to make Air-flow does not cause sinuous flow in the intersection of wide section 6 and transition 7, and the inner edge line of wide section 6 and transition 7 is at wide section 6 8 position of tie point with transition 7 is circular sliding slopes.3 lower end of gas-guide tube is inserted into from the top of cylinder, makes to hold level with both hands under gas-guide tube 3 Face is at the 2/3~3/4 of the vertical height H of spiral guide vane 2, i.e., the Partial Height h that gas-guide tube 3 stretches into cylinder is spiral guide vane The 2/3~3/4 of 2 vertical height H.In conjunction with the width gradual change structure of spiral guide vane 2, the part of cylinder is stretched into gas-guide tube 3, Middle upper semisection is contacted with 2 inside edge of spiral guide vane, and spiral guide vane 2 is separated by the gap between gas-guide tube 3 and cylinder completely. Gas-guide tube 3 stretches into the lower semisection of the part of cylinder, and as spiral guide vane 2 becomes narrow gradually, the inside edge of spiral guide vane 2 is gradually distance from Gas-guide tube 3 forms the structure of part segregated portion connection, on the one hand can keep the guiding role of spiral guide vane 2, on the other hand The continuous rotation for promoting air-flow avoids dust-contained airflow from not detaching the reduction for just being exported by gas-guide tube 3 and causing efficiency of dust collection also.
