Abstract

The invention discloses a chain structure for a rotary filtering net. The chain structure comprises a roller shaft, wherein two outer chain plates are respectively and fixedly connected at two ends of the roller shaft; a sleeve is sleeved on the roller shaft between the outer chain plates; an inner chain plate is fixedly connected to two ends of the sleeve; and the periphery of the sleeve is connected with a roller. According to the chain structure, the wear between the roller shaft and the inner chain plate can be reduced, and the wear of the chain part is eliminated after impurities are doped in an oil-free bearing, so that the service life of the chain of the rotary filtering net is prolonged, and the reliable operation of a water circulation system of a power station is guaranteed.

Description

The chain structure of rotary sieve
Technical field
The present invention relates to rotary sieve device field, relate in particular to the chain structure field of rotary sieve.
Background technique
Rotary sieve is the important component part in the water circulation system of power station, is used for filtering the impurity of the water that enters water circulation system, guarantees the normal operation of water circulation system.
Present rotary sieve generally all drags by chain, at the continuous low-speed running of vertical direction.At chaindriven two ends, chain need to turn round, and will rub this moment at the junction point of chain link.At present the chain structure of rotary sieve as shown in Figure 1, the outer plate 1 of chain and inner plate 6 are connected on the roller shaft 4; As shown in Figure 2, the two ends of roller shaft 4 are with tenon 7; Outer plate 1 joggle is on tenon 7, and inner plate 6 is connected on the roller shaft 4 by oilless bearing 9; Roller shaft 4 peripheries also are connected with roller 2, play leading role in the chain operation process.In actual use, because oilless bearing 9 is less with the surface of contact area of inner plate 6 and roller shaft 4, when turning round, can produce larger pressure, unstable wear at the surface of contact of inner plate 6 and roller shaft 4, cause shorten working life, affected the reliable operation of power station water circulation system.
In addition, oilless bearing 9 relies on the self lubricating material in the bearing matrix that oil-free lubrication is provided, and is comparatively responsive to impurity.Rotary sieve has very long one section minute time need to be immersed in the water in running, and sediment charge is generally larger in present China river, silt enters the slit of the drive chain of rotary sieve, and oilless bearing 9 is polluted, and has also accelerated the wearing and tearing of inner plate 6 and roller shaft 4.
Summary of the invention
The applicant is for short problem of serious wear in the above-mentioned existing rotary sieve chain structure, working life, carry out Improvement, the chain structure of another kind of rotary sieve is provided, can reduce the wearing and tearing of roller shaft and inner plate, eliminate simultaneously oilless bearing and mix behind the impurity wearing and tearing to chain part, thereby prolong the working life of rotary sieve chain, guarantee the reliable operation of power station water circulation system.
Technological scheme of the present invention is as follows:
A kind of rotary sieve chain structure comprises roller shaft, and two outer plates are fixedly connected on respectively the two ends of described roller shaft, and overlapping on described roller shaft between the outer plate has sleeve, inner plate to be fixedly connected on the two ends of described sleeve; The periphery of described sleeve also is connected with roller.
Its further technological scheme is: device has bearing between described sleeve and the described roller.
Beneficial effect of the present invention is:
Inner plate is fixedly connected with sleeve, has avoided the wearing and tearing of inner plate and sleeve; Compare the direct contact roller wheel shaft of inner plate, the area of contact of sleeve and roller shaft increases greatly, thereby pressure reduces, and can alleviate the wearing and tearing that roller shaft is subject to; Because the roller shaft wearing and tearing alleviate, and between sleeve and the roller shaft bearing can be set, thereby eliminate the phenomenon of being polluted unstable wear because of oilless bearing.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
, the present invention includes two ends and be fixedly connected on respectively on the first tenon 7 with 4, two outer plates 1 of roller shaft of the first tenon 7 to shown in Figure 5 such as Fig. 3, between the outer plate 1 on roller shaft 4 cover sleeve 3 is arranged; The two ends of sleeve 3 are with the second tenon 8, and inner plate 6 is fixedly connected on the second tenon 8; The periphery of sleeve 3 also is connected with roller 2 between inner plate 6; Device has oilless bearing 5 between sleeve 3 and the roller 2.
Above description is explanation of the invention, is not limitation of the present invention, and limited range of the present invention is referring to claim.In the situation that without prejudice to basic structure of the present invention, the present invention can do any type of modification.
