Description
Technical field
This utility model belongs to material transfer equipment technical field, is specifically related to a kind of bucket elevator axle sealing structure.
Background technology
In modern industry production process, elevator is widely used in the industry materials such as various cement chemical industry dry powder and mortars
Promote conveying, such as: coal, cement, broken after Ore etc..And on elevator the installation of dynamic power transmission shaft and lower drive shaft need with
Sealing between housing, the sealing between the most traditional upper power transmission shaft and housing uses monolayer seal with elastometic washer, its defect
Being that sealing effectiveness is bad, it is impossible to stop the leakage of dry powder and mortar, rubber ring is changed after damaging wastes time and energy, and needs equipment downtime
The rear replacing having dismantled rubber ring on a large scale.
Summary of the invention
This utility model solves the technical problem that and there is provided a kind of good sealing effect and be convenient for changing the bucket type of sealing ring
Elevator axle sealing structure.
This utility model adopts the following technical scheme that for solving above-mentioned technical problem, bucket elevator axle sealing structure, bag
Include axle sealing structure and lower axle sealing structure, it is characterised in that: upper axle sealing structure uses double seal ring structure, this double containment
Ring includes fixing seal ring and rotating seal ring, and wherein fixing seal ring is fixedly installed in the joint portion of housing and upper power transmission shaft
Position, the inner circle of this fixing seal ring is slidably matched with upper power transmission shaft, and the cylindrical of fixing seal ring is provided with annular groove, elevator
Upper shell plate and lower house plate be respectively embedded into the annular groove of fixing seal ring in and fixing with fixing seal ring is connected, revolve
The structure turning sealing ring is consistent with the structure of fixing seal ring, and it is upper that this rotating seal ring is fixedly installed in inside fixing seal ring
On power transmission shaft, rotating seal ring coordinates with fixing seal czermak space.
Further preferably, described fixing seal ring and rotating seal ring all use wear resistant nylon material to make.
Further preferably, the gap of 0.2-0.5mm is kept between described rotating seal ring and fixing seal ring.
This utility model installs rotating seal ring additional and improves the sealing effectiveness of power transmission shaft and housing, and can be used as
Backup seal reduces the trouble that the equipment downtime brought because changing sealing ring is dismantled on a large scale.

In figure: 1, housing, 2, upper power transmission shaft, 3, chain, 4, lower drive shaft, 5, elevator bucket, 6, fixing seal ring, 7, rotate
Sealing ring.
Detailed description of the invention
Particular content of the present utility model is described in detail in conjunction with accompanying drawing.As Figure 1-3, at the housing 1 of bucket elevator
Inside being provided with lifting device, power passes to lifting device by upper power transmission shaft 2, chain 3 drive lower drive shaft 4 to carry out transmission, enter
And drive the elevator bucket 5 being arranged on chain 3 that material is risen to the upper outlet of elevator by the bottom feed end of elevator
End, is sent into hopper, and upper shaft sealing unit is arranged on the binding site at power transmission shaft 2 two ends and housing 1, and lower sealing unit is arranged
At the binding site at lower drive shaft 4 two ends Yu housing 1, upper shaft sealing unit uses double seal ring structure, and this double seal ring includes
Fixing seal ring 6 and rotating seal ring 7, fixing seal ring 6 and rotating seal ring 7 all use wear resistant nylon material to make, wherein
Fixing seal ring 6 is fixedly installed in the binding site of housing 1 and upper power transmission shaft 2, the inner circle of this fixing seal ring 6 and upper power transmission shaft
2 are slidably matched, and the cylindrical of fixing seal ring 6 is provided with annular groove, and upper shell plate and the lower house plate of elevator are respectively embedded into
Fix in the annular groove of fixing seal ring 6 and with fixing seal ring 6 and be connected, the structure of rotating seal ring 7 and fixing seal
The structure of ring 6 is consistent, and this rotating seal ring 7 is fixedly installed on the upper power transmission shaft 2 inside fixing seal ring 6, rotating seal ring 7
And keep the gap of 0.2-0.5mm between fixing seal ring 6.
In bucket elevator normal operation, rotating seal ring rotates with upper power transmission shaft, and fixing seal ring keeps
Static, the matched in clearance between rotating seal ring and rotating seal ring forms face seal, between fixing seal ring and upper power transmission shaft
Coordinated by high-precision slide and reach preferable sealing effectiveness；After fixing seal ring weares and teares with upper power transmission shaft long time running,
The upper shell plate of elevator can be pulled down, then rotating seal ring exits and be fixed on the position continuation of former fixing seal ring
Using, such rotating seal ring can form face seal with fixing seal ring before fixing seal ring lost efficacy and reach preferably to improve
Sealing effectiveness, also can reduce, as backup seal, the trouble that the equipment downtime brought because changing sealing ring is dismantled on a large scale.
Of the present utility model ultimate principle, principal character and advantage are more than shown and described, new without departing from this practicality
On the premise of type spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within requirement and protect
The scope of the present utility model protected.
