Card slot is formed between intermediate terrace, the pilot hole on the pilot hole on lip ring and top hoop is located on same axis, positioning pin
Lip ring and top hoop are connected across pilot hole and are fixed.
Preferably, in the assembled condition, the outer ring surface of lip ring and top hoop inner peripheral surface against.
Preferably, it is fixedly installed with limited block on lip ring and positioned at the bottom of groove, which has and lip ring
On the coaxially arranged pin hole passed through for positioning pin of pilot hole.
Preferably, multiple hanging rings are fixedly installed on lip ring and positioned at bottom portion of groove, each hanging ring is on lip ring around institute
It is uniformly distributed to state through-hole annular.
Preferably, the second lug boss is flushed far from the side of in-between terrace with lower terrace surfac.
Preferably, hoop outside in top is equipped with third protrusion portion.
Preferably, intermediate terrace is equipped with upper arc groove close to the side of upper terrace, and lip ring lower surface is equipped with lower arcuate slot,
And when lip ring and top hoop are in assembled state, the upper arc groove is positioned opposite to be formed between with lower arcuate slot
Card slot.
Preferably, expansion loop is installed on the inside of through-hole.
In the present invention, end for being mounted on rotary drum bind round on top, make the port of lower terrace surfac and rotary drum against, inner circumferential surface and
The outer surface of rotary drum against;Lip ring is used to cooperate with top hoop, makes have card slot therebetween, for the ring at filter bag port
It is caught in, specific mounting means is: top hoop being mounted on rotary drum, and the ring at filter bag port is stuck in intermediate terrace, so
Afterwards by lip ring and top hoop assembly, so that the upper port of filter bag is firmly fixed between top hoop and lip ring, the structure is steady
It is fixed reliable, and disassembly is easy for installation, greatly facilitates the replacement of filter bag.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fixed mechanism on a kind of easy-to-mount filtering bag of centrifuge proposed by the present invention;
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.
Specific embodiment
In the following, technical solution of the present invention is described in detail by specific embodiment.
As shown in Figs. 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.
Referring to Fig.1-2, fixed mechanism on a kind of easy-to-mount filtering bag of centrifuge that the embodiment of the present invention proposes, comprising:
Top hoop 1, lip ring 2 and positioning pin 3, in which:
For 1 inside of top hoop equipped with the first lug boss 11, the first lug boss 11 is convex for the ring-type enclosed along top 1 inner peripheral surface of hoop detour one
It rises, and is reserved with spacing between the upper and lower end face of the first lug boss 11 and the upper and lower end face of top hoop 1, in the first lug boss
Upper terrace is formed between 11 upper surface and the inner peripheral surface of top hoop 1, in the lower end surface of the first lug boss 11 and the inner peripheral surface of top hoop 1
Between form lower terrace surfac;First lug boss 11 is equipped with the second lug boss 12 far from the side of top hoop 1, and the second lug boss 12 is and the
The coaxially arranged annular projection of one lug boss 11, the second lug boss 12 have between the surface and upper terrace of upper terrace side
Spacing forms intermediate terrace, and intermediate terrace is equipped with upper arc groove close to the side of upper terrace, and the second lug boss 12 is far among it
The side of terrace is flushed with lower terrace surfac.It binds round 1 side wall and is located at the top of upper terrace equipped with the dress radially extended and both ends penetrate through in top
Distribution.Lip ring 2 is circular slab, and the upper surface of lip ring 2 is equipped with Xiang Qixiang surface direction and extends and coaxially arranged with lip ring 2
Groove;The bottom of groove is equipped with the through-hole coaxially arranged, is equipped with expansion loop 6 on the inside of through-hole;The side wall of groove is equipped with
Radially extend and both ends perforation pilot hole;2 lower surface of lip ring is equipped with lower arcuate slot.
Lip ring 2 is used to be assembled with top hoop 1, makes it in the assembled condition, outer ring surface and the top hoop 1 of lip ring 2
Inner peripheral surface is against, the lower surface of lip ring 2 and upper terrace against and upper arc groove and 2 lower surface of lip ring on intermediate terrace
The lower arcuate slot at place is positioned opposite to form card slot between;In the assembled condition, the pilot hole on lip ring 2 and top are bound round
Pilot hole on 1 is located on same axis, and positioning pin 3, which passes through pilot hole, makes lip ring 2 connect and fix with top hoop 1.
In the present invention, top hoop 1 makes the port of lower terrace surfac and rotary drum against inner circumferential surface for being mounted on the end of rotary drum
With the outer surface of rotary drum against;Lip ring 2 is used to cooperate with top hoop 1, makes have card slot therebetween, at filter bag port
Ring is caught in, and specific mounting means is: top hoop 1 being mounted on rotary drum, and the ring at filter bag port is stuck in scala media
Face, then by 1 assembly of lip ring 2 and top hoop, so that the upper port of filter bag is firmly fixed between top hoop 1 and lip ring 2,
The stable structure is reliable, and disassembly is easy for installation, greatly facilitates the replacement of filter bag.
In addition, being fixedly installed with limited block 4 on lip ring 2 and positioned at the bottom of groove, the limited block 4 in the present embodiment
With with the coaxially arranged pin hole passed through for positioning pin 3 of pilot hole on lip ring 2, to facilitate the quick assembling of positioning pin 3.
In the present embodiment, multiple hanging rings 5 are fixedly installed on lip ring 2 and positioned at bottom portion of groove, each hanging ring 5 is on lip ring 2 around institute
It is uniformly distributed to state through-hole annular, to facilitate the place for having elevator or grasping when pickup.Similarly hoop 1 outside in top is equipped with third protrusion
Portion 13, in order to there is the place for grabbing card in pickup.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
