Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.

Fig. 1 to Fig. 6 is please referred to, the utility model embodiment includes:

A kind of sealing structure of recuperation of heat runner, comprising: be fixed in recuperation of heat rotor shell 11 and set around runner 12 The fixed ring 2 set is fixed in the fixed ring 2 and around the outer hairbrush 3 of the setting of fixed ring 2, is fixed about outside runner 12 Interior hairbrush 5 on circle, and be fixed on recuperation of heat runner central sill 13 and along the middle hairbrush 7 of 13 length direction of central sill setting；By In on recuperation of heat runner 1 there are two central sill 13, so there are two middle hairbrush 7 is also corresponding, to guarantee corresponding on a central sill 13 There is a middle hairbrush 7.There are two the fixed rings 2, and two fixed rings 2 are located at the two sides of recuperation of heat rotor shell 11；By In there are two fixed rings 2, other than institute hairbrush 3 it is also corresponding there are two, to guarantee to be corresponding with an outer hairbrush in each fixed ring 2 3.There are two the Interior hairbrush 5, and two Interior hairbrush 5 are arranged respectively close to two fixed rings 2.The cross section of the fixed ring 2 is in U Font, the fixed ring 2 include the outer panel 21 being fixedly connected with the shell 11, the inside opposite with 12 end face of runner Plate, and the bottom plate 23 of the connection outer panel 21 and interior plate.One end of the outer hairbrush 3 is pressed in using outer tabletting 4 fixation On the bottom plate 23, the other end of the outer hairbrush 3 is against on the end face of the runner 12；A side of the outer tabletting 4 with The bottom plate 23 is fixedly connected, and the outer fixation of hairbrush 3 is compressed on the bottom plate 23 by another side of the outer tabletting 4； Since outer hairbrush 3 is fixed on the inner ring of fixed ring 2, so outer hairbrush 3 can be well fixed on using outer 4 fixation of tabletting On bottom plate 23, good fixing effect；Outer hairbrush 3 realizes the sealing of 12 outer ring of runner.One end of the Interior hairbrush 5 uses self-tapping screw (not shown) is fixed on the outer ring of the runner 12, and the other end of the Interior hairbrush 5 is against on the interior plate；Due to Interior hairbrush 5 are packaged on runner 12, thus it is fixed simple using self-tapping screw, conveniently, it is at low cost, while can also play Good fixed effect；Interior hairbrush 5 realize the sealing of 12 inner ring of runner, and Interior hairbrush 5 and outer hairbrush 3 can make up double-layer seal knot Structure can play good sealing effect when air-flow passes through runner 12.Press strip 8 is fixed in one end use of the middle hairbrush 7 On the central sill 13, the other end of the middle hairbrush 7 is against on the end face of the runner 12；A side of medium pressure item 8 It is fixedly connected with the central sill 13, the middle fixation of hairbrush 7 is compressed on the central sill 13 by another side of medium pressure item 8 On；Since middle hairbrush 7 is fixedly installed along 13 length direction of central sill, so press strip 8 fixes 7 energy of hairbrush in limitation in Fixed restriction effect well is enough played, existing local crowning will not be rotated out of with runner 12 to influence showing for sealing effect As, and then can guarantee preferable sealing effect.It is provided with two layers of middle hairbrush 7 on the central sill 13, central sill can be reinforced Situations such as being sealed at 13, guarantee the leakproofness between central sill 13 and runner 12, effectively preventing air-flow mixed flow and leakage.It is described outer Hairbrush 3 includes the brush 31 for the fixed part 32 of fixed installation and for cooperating sealing；The fixed part 32 is L-shaped, institute State fixed part 32 one end it is vertical with the brush 31 be fixedly connected, the other end of the fixed part 32 has to far from hairbrush The inclined bending part 33 in 31 side of portion；Fixed part 32 can carry out pressure convenient for outer tabletting 4 and set fixation, and bending part 33 can make to fix Portion 32 is fitted in well on bottom plate 23, is further ensured that leakproofness when outer hairbrush 3 is fixed.The Interior hairbrush 5 and it is described in The structural principle of hairbrush 7 is identical as the structural principle of the outer hairbrush 3 so that Interior hairbrush 5 guarantee itself and 12 outer ring of runner it Between leakproofness, so that middle hairbrush 7 is guaranteed its leakproofness between central sill 13.

The utility model can play good sealing effect, and the double-deck hair brush structure on runner 12 can be avoided effectively Situations such as air-flow mixed flow and leakage, the working efficiency of recuperation of heat runner 1 is increased, mass energy is saved；Its structure is simple, pacifies It fills easy to operate.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
