Description
[technical field]
The present invention relates to the seal arrangement of a kind of acid tank with roller.
[background technique]
In a lot of band steel processing lines, acid tank equipment is arranged all, the sinking roller is housed in the acid tank.The two ends of roller will be stretched out the acid tank wall and be supported thereon, and this just needs sealing configuration, and existing sealing configuration all is equipped with axle spring, is used to provide axial force to guarantee that dynamic and static sealing surface fits tightly, and can not leak.But, this complex structure, cost height, inconvenient installation and maintenance.
[summary of the invention]
The present invention has overcome the deficiencies in the prior art, and the seal arrangement of a kind of simple in structure, acid tank of making things convenient for installation and maintenance with roller is provided.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of acid tank seal arrangement of roller, it is characterized in that including the live-rollers that is arranged in the acid tank, stretch out respectively outside the acid tank wall at the two ends of described live-rollers, be arranged with the elastic packing ring member that right edge is fixedlyed connected with the acid tank wall on the surface outside live-rollers stretches out the acid tank wall, on live-rollers, be arranged with the rotary seal ring member that right edge contacts with the sealing of elastic packing ring member, be provided with locking nut in the live-rollers end the locking of rotary seal ring member.
Aforesaid a kind of acid tank is characterized in that with the seal arrangement of roller described elastic packing ring member includes elastic rubber ring and stationary ring, and the right edge of elastic rubber ring is fixedlyed connected with the acid tank wall, and the limit, left side of elastic rubber ring is connected with stationary ring.
Aforesaid a kind of acid tank seal arrangement of roller, it is characterized in that described rotary seal ring member includes rotating seat and the rotating ring that is installed on the rotating seat, the right edge of described rotating ring closely contacts with stationary ring, and described locking nut roof pressure is on the limit, left side of rotating seat.
Aforesaid a kind of acid tank is characterized in that with the seal arrangement of roller described live-rollers includes roll body and the roll shaft that is connected the roll body two ends, is provided with outside thread on roll shaft, and described locking nut is threaded on the outside thread.
The present invention compared with prior art has following advantage:
The present invention has cancelled the seat ring of spring utilizing the elastic packing ring member to replace existing spring assembly, and simplified structure makes things convenient for installation and maintenance.
[description of drawings]
Fig. 1 is a cut-away view of the present invention.
[embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in the figure, a kind of acid tank includes the live-rollers 1 that is arranged in the acid tank with the seal arrangement of roller, and stretch out respectively outside the acid tank wall 5 at the two ends of described live-rollers 1.Be arranged with the elastic packing ring member 2 that right edge is fixedlyed connected with the acid tank wall on the surface outside live-rollers 1 stretches out the acid tank wall, make elastic packing ring member 2 transfixions.Be arranged with the rotary seal ring member 3 that 2 sealings of right edge and elastic packing ring member contact on live-rollers 1, rotary seal ring member 3 is to be fixed on the live-rollers 1 and with its rotation.Then rotary seal ring member 3 then can occur relatively rotating with two faces that 2 sealings of elastic packing ring member contact, thereby can make two contacted friction mutually.
Be provided with the locking nut 4 that rotary seal ring member 3 is locked in described live-rollers 1 end.
As the optimal way of present embodiment, described elastic packing ring member 2 includes elastic rubber ring 21 and stationary ring 22, and the right edge of elastic rubber ring 21 is fixedlyed connected with the acid tank wall, and the limit, left side of elastic rubber ring 21 is connected with stationary ring 22.
As the optimal way of present embodiment, described rotary seal ring member 3 includes rotating seat 32 and the rotating ring 31 that is installed on the rotating seat 32, and the right edge of described rotating ring 31 closely contacts with stationary ring 22, and described locking nut 4 roof pressures are on the limit, left side of rotating seat 32.
As the optimal way of present embodiment, described live-rollers 1 includes roll body 11 and is connected the roll shaft 12 at roll body 11 two ends, is provided with outside thread on roll shaft 12, and described locking nut 4 is threaded on the outside thread.
Because stationary ring 22 is fixed, and rotating ring 31 is followed live-rollers 1 rotation, and then stationary ring 22 is made frictional rotation with the sealing surface of rotating ring 31.Like this service time of a specified duration after, have wearing and tearing, the axial force of sealing surface can reduce, sealing effect is not all right.Only need the rotational lock nut this moment, and locking nut is pushed away rotating ring 31 forward, and pressure elasticity rubber ring 21 increases axial force, makes sealing effect recover normal state, regulates simple, easy to use.
