Or imply that signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore be not understood that
For the limitation to scope of protection of the utility model.
The utility model provides a kind of sealing structure for being used to fix floating type cyclone, as shown in figure 1, including fixed board
1 with pressing plate 2, fixed board 1 and pressing plate 2 is hollow annular construction, and the outer face of fixed board 1 is provided with welding ends, to be welded with plenum chamber
Connect, pressing plate 2 is detachably attached in the ring-type plate face of fixed board 1, and annular groove 5, the openings of annular groove 5 are formed between fixed board 1
To the center towards the floating type cyclone, to accommodate the outer end of the floating type cyclone.
It should be noted that fixed board 1 is respectively provided with interior outside with pressing plate 2, it can be Q-RING or the circle of standard
Ring structure, the Q-RING refer to that symmetrical centre overlaps, and the part between two parallel squares, the present embodiment are distinguished in four sides
In, according to the inner edge of the concrete structure design pressing plate of floating type cyclone, floating type cyclone is generally class sector structure not
Rule body, fixed board are then the irregular shape of class Q-RING with pressing plate, for convenience of description, represent fixed with internal diameter or external diameter below
The interior outside size relation in any section of plate or pressing plate, it is impossible to understand fixed board in the present embodiment and the protection model of pressing plate
Enclose and be defined to circular ring structure.
As described above, fixed board 1 and pressing plate 2 are cyclic structure, the floating type cyclone of ring-type is fixed to plenum chamber by it
Principle is as shown in Figure 2.The accompanying drawing is schematic cross-section, and 6 be plenum chamber, and 7 be floating type cyclone, floating type cyclone 7 it is outer
End face is accommodated by the annular groove 5 just, and the size of annular groove 5 matches the outer face size of the floating type cyclone 7, in fact,
It is to fix the floating type cyclone crimping, or is interference fit.And the welding ends 13 that the outer face of fixed board 1 is set being capable of jail
Solid the sealing structure is fixed on plenum chamber, so as to which the floating type cyclone is fixed on plenum chamber.
In the present embodiment, the outside dimension of the fixed board 1 adapts to the cylinder external diameter of plenum chamber, the internal diameter size of fixed board 1
Less than the external diameter of floating type cyclone 7, so as to which floating type cyclone 7 is placed on fixed board 1, in addition, the outside dimension of pressing plate 2 is big
Internal diameter size in fixed board 1 and the outside dimension less than floating type cyclone 7, so as to which floating type cyclone 7 is crimped onto
On fixed board 1.The step of floating type cyclone is fixed to plenum chamber, or change the installation steps of sealing structure and include：
Fixed board 1 and plenum chamber 6 are welded；
Floating type cyclone 7 is positioned on fixed board 1；
Pressing plate 2 is crimped onto on floating type cyclone 7, and pressing plate and fixed board 1 are fixed.
Fig. 3 and Fig. 4 is the building block detailed maps of the present embodiment sealing structure.Fig. 3 is that the concrete structure of fixed board 1 shows
It is intended to, with reference to figure 3, the fixed board 1 includes extruded segment 11 and canned paragraph 12 from the inside to the outside, and the plate face thickness of the extruded segment 11 is low
In the plate face thickness of canned paragraph 12, the pressing plate 2 is detachably connected at the extruded segment 11, with reference to figure 4, pressing plate 2 by it is interior extremely
Include placement section 21 and joining section 22 outside, the plate face thickness of the placement section 21 is less than the thickness of joining section 22, so that described
The annular groove 5 is formed between placement section 21 and extruded segment 11.
It is understood that the above-mentioned design (or referred to as design of step) to plate face thickness causes sealing structure from whole
In seamlessly transitting from the point of view of on body, in the absence of protrusion or the place of depression, therefore, the plate face thickness of the joining section 22 is not more than
The difference of the plate face thickness of the canned paragraph 12 and the plate face thickness of extruded segment 11, with reference to figure 1, it is however generally that, the plate of joining section 22
Face thickness is slightly less than the difference of the plate face thickness of the canned paragraph 12 and the plate face thickness of extruded segment 11, to place sealing structure,
For example, after the second pad 32 is placed between the two, just cause the right side plate face of pressing plate 2 with the right plate of fixed board 1 in face of neat,
In alternate embodiment, fixed board 1 can be the ring-type board face structure of rule, and pressing plate 2 only is done into step processing to form annular groove；Or
Person's pressing plate 2 can be the ring-type board face structure of rule, and fixed board 1 only is done into step processing to form annular groove, this practicality can be achieved
New purpose.
In the present embodiment, foregoing welding ends 13 is located on canned paragraph 12, and the canned paragraph is fixed into plenum chamber.
It is circumferentially arranged in the extruded segment 11 of the fixed board 1 to have some screws, the engagement of the pressing plate 2 referring again to Fig. 1
The corresponding position of section 22 is provided with the matching screw of identical quantity, and the extruded segment 11 passes through the second spiral shell with the joining section 22
Bolt 42 connects, and the quantity of screw is 10-20.For example, circumferentially arranged in extruded segment 11 have 16 screws, it is right on joining section 22
Answer position to set and be also provided with 16 screws.
As shown in figure 1, the present embodiment also includes some pads, be mainly used in preventing flow leakage, including extruded segment 11 with
The second pad 32 set between joining section 22, the first pad 31 that the opening position of installation bolt is set on canned paragraph 12, pressing plate 2
Placement section 21 in the 3rd pad 33 set with the floating type cyclone contact position.Pad typically selects elastomeric material system
Into.
It is circumferentially arranged at above-mentioned canned paragraph 12 to have some screws in the present embodiment, and the first bolt 41 is equipped with, in fixed board
1 is due to observation or other demands the reason for being provided with screw at this and opens up, and when not in use, passes through the first bolt 41 and the
One pad 31 is sealed.
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than it is limited
System.Although the utility model is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art should manage
Solution：It can still be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model
The spirit and scope of technical scheme.
