Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
Embodiment mono-:
As shown in Figure 2 and Figure 3, cylindrical shell 11 of the present utility model comprises top vertical tube part 5 and bottom cone cylinder portion 7, at cylindrical shell 11 periphery walls, has at least two vertical ribs 4, and the present embodiment is provided with four vertical ribs 4 of circumference uniform distribution.Vertical rib 4, from vertical tube part 5 top side end faces, extends downward part cone cylinder portion 7 and finishes; Vertical rib 4 can be squarish at the rib cross section of vertical tube part 5 peripheries, can be also circular arc or other shapes, bores cylinder portion 7 peripheries while finishing when extending to, and has formed the local step surface 6 that is greater than vertical tube part 5 external circumferential ribs sliver transvers sections.Certainly, also can extend to cone cylinder portion 7 peripheries and finish, and directly finish in vertical tube part 5 peripheries, direct like this using rib cross section as local step surface 6, although the less carrying object that can realize equally of loading end.
The local step surface 6 of vertical rib of the present utility model 4 bottom sides has larger area, and carrying is uniform and stable more.Simultaneously vertical rib 4 has played the effect of reinforcement to a certain extent, to improving cyclone cylinder intensity, preventing its torsional deformation in the time firing, prevents from hardening cracking, and all can play important effect.
As shown in Figure 4, loading plate 3 of the present utility model is no longer positioned at the bottom of cylindrical shell 11, but rises to the periphery wall of cylindrical shell 11 central authorities, comprises the periphery wall of vertical tube part 5 or cone cylinder portion 7.In the time that assembling cyclone separator is installed, only need cylindrical shell 11 directly to lift to loading plate 3, directly fall into circular hole 8, the cylindrical shell outer circumference diameter of local step surface 6 At The Heights of vertical rib 4 bottom sides of the diameter of circular hole 8 and cylindrical shell 11 is suitable, there is fit clearance, to prevent that tension from coordinating, cylindrical shell 11 is produced to lateral pressure crushing cylindrical shell 11.The local step surface 6 of four vertical ribs 4 contacts with loading plate 3, can bear the weight of cylindrical shell 11 balance and stability, this load is normal pressure and do not have side force, neither can produce extruding force radially to cylindrical shell 11, unstable also can not cause cyclone separator work time.As shown in Figure 5, symmetrical four the uniform vertical ribs 4 of cylindrical shell 11 peripheries lay respectively at four 45 degree positions while arranging, like this in the time that arranged in arrays forms cyclone separator, adjacent cylindrical shell 11 still can be close to, and vertical rib 4 is just in time positioned at the clearance spaces in its bight, therefore whole cyclone separator does not need to increase additional space, has ensured the compactness of system.
Embodiment bis-:
As shown in Figure 6, Figure 7, in vertical tube part 5 and cone cylinder portion 7 intersections of cylindrical shell 11, the periphery of vertical tube part 5 is continued to form annular table terrace 10 as loading end to downward-extension one segment distance.Due to annular table terrace 10 entirety continuously, thereby carry stressed more even reasonable.Meanwhile, the basic uniformity of this structure wall thickness, be not easy because the internal stress that wall unevenness produces ftractures, thereby yield rate is higher in the time firing.
Fig. 8 is the another kind of embodiment of cylindrical shell 11, and the top wall thickness of vertical tube part 5 is thicker, and bottom wall thickness is thinner, and wall thickness change place forms annular table terrace 10, plays equally carrying effect.
As shown in Figure 7, the height and position of step surface of the present utility model, is positioned at taking vertical tube part 5 and bores cylinder portion 7 intersecting lenses as center line, and the region in the middle part 2/3H of cylindrical shell 11 overall total heights, preferably in the region of H/2.
As shown in Figure 9, the loading plate 3 of embodiment mono-and embodiment bis-moves to cylindrical shell 11 middle parts on all, substantially vertical tube part 5 and cone cylinder portion 7 intersecting lenses up and down near, utilize local step surface 6 or annular table terrace 10 to carry cyclone cylinder 1.Thereby being fixed when sealing, only thermal insulation concrete 9 need to be poured between adjacent cyclone cylinder 1, owing to there not being the large space of bottom between adjacent circular cone, thereby the consumption of thermal insulation concrete 9 greatly reduces, and the weight of whole cyclone separator at least can reduce more than 15%.After moving on loading plate 3, flue-dust retainer 16 moves on also can be corresponding, thereby the height of whole equipment also can reduce.Simultaneously because the thermal insulation concrete 9 for fixing is fewer, and enbrittle after long-term use, after therefore simply destroying thermal insulation concrete 9, just can change easily the cylindrical shell 11 of cracking gas leakage, thereby having extended significantly the service life of cyclone separator.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and without prejudice to the utility model spirit in the situation that, the utility model can be done any type of amendment.
