Lip ring is set to be connected with top hoop and fixed through pilot hole.
Preferably, in the assembled condition, the outer ring surface of lip ring with top hoop inner peripheral surface against.
Preferably, on lip ring and limited block is installed with positioned at the bottom of groove, the limited block has and lip ring
On the coaxially arranged pin-and-hole passed through for alignment pin of pilot hole.
Preferably, on lip ring and multiple suspension ring are installed with positioned at bottom portion of groove, each suspension ring are on lip ring around institute
State through hole annular uniform.
Preferably, side of second lug boss away from its middle terrace is flushed with lower terrace surfac.
Preferably, hoop outside in top is provided with the 3rd lug boss.
Preferably, middle terrace is provided with upper deep-slotted chip breaker close to the side of upper terrace, and lip ring lower surface is provided with lower arcuate slot,
And when lip ring is in confined state with top hoop, the upper deep-slotted chip breaker and lower arcuate slot are positioned opposite to be formed between
Neck.
Preferably, expansion loop is installed on the inside of through hole.
In the present invention, top hoop is used for installed in the end of rotary drum, make the port of lower terrace surfac and rotary drum against, inner circumferential surface with
The outer surface of rotary drum against;Lip ring is used to coordinate with top hoop, makes have neck therebetween, for the ring of filter bag port
It is caught in, its specific mounting means is:Top hoop is arranged on rotary drum, and the ring of filter bag port is stuck in middle terrace, so
Afterwards by lip ring and top hoop assembling so that the upper port of filter bag is firmly fixed between top hoop and lip ring, and the structure is steady
It is fixed reliable, and remove and install conveniently, greatly facilitate the replacing of filter bag.

Embodiment
Below, technical scheme is described in detail by specific embodiment.
As shown in Figure 1-2, Fig. 1 is the structure of fixed mechanism on a kind of easy-to-mount filtering bag of centrifuge proposed by the present invention
Schematic diagram;Fig. 2 is the schematic cross-section of fixed mechanism on a kind of easy-to-mount filtering bag of centrifuge proposed by the present invention.
Fixed mechanism on reference picture 1-2, a kind of easy-to-mount filtering bag of centrifuge that the embodiment of the present invention is proposed, including:
Top hoop 1, lip ring 2 and alignment pin 3, wherein:
Top hoop 1 inner side be provided with the first lug boss 11, the first lug boss 11 be along top hoop 1 inner peripheral surface detour a circle ring-type it is convex
Rise, and spacing is reserved between the upper and lower end face of the first lug boss 11 and the upper and lower end face of top hoop 1, with the first lug boss
Upper terrace is formed between 11 upper surface and the inner peripheral surface of top hoop 1, in the lower surface of the first lug boss 11 and the inner peripheral surface of top hoop 1
Between form lower terrace surfac;Side of first lug boss 11 away from top hoop 1 is provided with the second lug boss 12, and the second lug boss 12 is and the
The coaxially arranged annular projection of one lug boss 11, the second lug boss 12 has between the surface of upper terrace side and upper terrace
Spacing forms middle terrace, and middle terrace is provided with upper deep-slotted chip breaker close to the side of upper terrace, and the second lug boss 12 is away from the middle of it
The side of terrace is flushed with lower terrace surfac.Top hoop 1 side wall and positioned at upper terrace top be provided with radially extend and two ends insertion dress
Distribution.Lip ring 2 is circular slab, and the upper surface of lip ring 2, which is provided with to it to surface direction, to be extended and coaxially arranged with lip ring 2
Groove;The bottom of groove is provided with the inside of the through hole for being coaxial therewith arrangement, through hole and is provided with expansion loop 6;The side wall of groove is provided with
