Embodiment
For making those of ordinary skill in the art clearly understand the purpose of this utility model, technical scheme and advantage, below in conjunction with accompanying drawing 1-3 and embodiment, the utility model is further elaborated.
A kind of scaling powder recycling device, include a collector 10, discharge pipe 30 that the exhaust column 20 and of the described collector of multiple access 10 is communicated in described collector 10, wherein, described collector 10 is provided with a thermal insulation layer 100, makes described collector 10 have heat insulation function.
During use, described exhaust column 20 is connected to the bottom surface of described collector 10, and described discharge pipe 30 is connected to a side of described collector 10.Exhaust column 20 extracts the scaling powder smog in stove, and the scaling powder smog that each exhaust column 20 extracts is pooled to collector 10, and the scaling powder smog collected is sent in wind chamber through discharge pipe 30, to realize the recovery of scaling powder smog.Described thermal insulation layer 100 can ensure that scaling powder smog is consistent with collector 10 inner wall temperature, avoids scaling powder smog to be condensed into by gaseous state in transport process solid-state, prevents scaling powder from blocking collector 10.
This thermal insulation layer 100 can have multiple embodiment, such as form thermal insulation layer at collector 10 outer wrapping heat-barrier material, or collector is designed to internal layer 101, skin 102, airtight air between this internal layer 101 and outer 102 forms this thermal insulation layer 100, or collector is designed to internal layer 101, skin 102, the heat-barrier material arranged between this internal layer 101 and outer 102 forms thermal insulation layer 100.Described heat-barrier material is alumina silicate heat-preservation cotton etc.
The casing 103 and one that described collector 10 includes a upper surface opening is covered on the upper cover 104 of described casing 103.One side of described upper cover 104 and a side chain connection of described casing 103, connect as adopted hinge 106.The free side edge of described upper cover 104 is provided with the pulling buckle 107 for described upper cover 104 being anchored on described casing 103.The design achieves quick unlatching, the closedown of upper cover 104, can clear up the film of flux residue in collector quickly and easily.Described collector 10 can be the shape such as tubulose, cuboid, in order to manufacture, easy to use be preferably rectangular structure.
