Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: as shown in connection with fig. 1-3, comprises a drum body 1; an air guide shell 2 is arranged on the outer side of the drum body 1; the air guide shell 2 is welded with the drum body 1; the air guide shells are symmetrically arranged on the outer side of the drum body 1 in pairs; an air guide passage 3 is formed between the air guide shell 2 and the outer wall of the drum body 1; an air inlet area 201 is arranged at one end of the air guide shell 2; the air inlet area 201 is provided with a plurality of radiating fins 101; the radiating fins 101 are welded with the outer wall of the drum body 1; an air increasing shell 4 is arranged outside the air inlet area 201; the air increasing shell 4 is welded with the air guide shell 2; an air outlet area 203 is arranged at the other end of the air guide shell 2; a main dust removal opening 102 is arranged between the air outlet areas 203 on the two sides; a speed change area 202 is arranged between the air inlet area 201 and the air outlet area 203; an auxiliary dust removal port 103 is arranged at a position of the drum body 1 corresponding to the speed change area 202; the plurality of radiating fins 101 are axially and symmetrically arranged in the air inlet area 201; the radiating fins 101 on the two sides are obliquely arranged towards the middle part; the axial width of the air guide shell 2 from the air inlet area 201 to the speed changing area 202 to the air outlet area 203 is gradually narrowed; the distance between the air guide shell 2 and the drum body 1 is from an air inlet area 201, a speed change area 202 to an air outlet area 203; the spacing is narrowed and widened again by the width.
