Except purpose described above, feature and advantage, the present invention also has other purpose, feature and advantage.The below is with reference to figure, and the present invention is further detailed explanation.

Description of drawings

The accompanying drawing that consists of the application's a part is used to provide a further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:

Fig. 1 is the provision for disengagement that is used for the unloading disc of the preferred embodiment of the present invention and the schematic diagram that cooperates of disc; And

Fig. 2 is the structural representation of the provision for disengagement that is used for the unloading disc of the preferred embodiment of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.

Referring to Fig. 1 and Fig. 2, the preferred embodiments of the present invention provide a kind of provision for disengagement for the unloading disc, are used for the disc 1 that is fixed on the line shaft 2 is dismantled, and disc 1 is arranged in the burner inner liner 3; Provision for disengagement comprises the sleeve 10 that clamps disc 1, fixed muffle 20 that sleeve 10 is fixing and is arranged on adjustable compressing member 30 on the fixed muffle 20; Wherein, disc 1 is arranged in the sleeve 10, and sleeve 10 comprises the first sleeve 11 and the second sleeve 12 that matches with the first sleeve 11, the end of compressing member 30 contact line shafts 2.According to provision for disengagement of the present invention, sleeve 10 is fixed and be combined into to the first sleeve 11 and the second sleeve 12 by fixed muffle 20, sleeve 10 clamps disc 1, to be fixed on compressing member 30 contacts on the fixed muffle 20 in the end of line shaft 2, compress the pressure of line shaft 2 by increasing compressing member 30, line shaft 2 is separated with disc 1, thereby with disc 1 dismounting, unload convenient and simple and time saving and energy saving, therefore pressure-acting can not destroy the dynamic balancing of disc 1 and line shaft 2 in the end of line shaft 2.

Sleeve 10 comprises the first sleeve 11 and the second sleeve 12 that matches with the first sleeve 11; When needs dismounting disc 1, the first sleeve 11 and the second sleeve 12 separately are installed between disc 1 and the burner inner liner 3 convenience quick for installation.Preferably, the first sleeve 11 and the second sleeve 12 are symmetrical about the axis of sleeve 10.The end of the first end of the first sleeve 11 and the second sleeve 12 is provided with inward flange 111, inward flange 111 contacts are between the internal face and disc 1 of burner inner liner 3, when exerting pressure to line shaft 2, inward flange 111 supports disc 1, with convenient disc 1 is separated with line shaft 2.The center of the second end that sleeve 10 is relative with first end is provided with inner groove 112.
