Abstract
The utility model provides a moist leaf machine sealing device of drum -type, includes: sealing ring, fixing device, sealing ring adopt the preparation of wear resistant flexible material, and the sealing ring has top surface and lateral wall, and the sealing ring tangent plane is the L type of inversion, and the top surface is greater than 90 degrees with the contained angle of lateral wall. During the use, the lateral wall of sealing ring is flexible dynamic contact state with the cylinder of moist leaf machine because the contained angle of sealing washer top surface and lateral wall is greater than 90 degrees, the sealing washer can keep all the time with cylinder in close contact with.
Description
Technical field
The utility model is related to a kind of sealing device, more particularly to a kind of cylindrical seal device of tobacco leaf moisting machine rotary drum.
Background technology
At present, in the industry the tangent plane of the sealing device of same type equipment is plane or the conical surface, and sealing device is line with cylinder
Contact, after contact surface abrasion 1-2mm of sealing ring, internal diameter of the seal ring becomes big, and sealing ring inner ring loosens with cylinder contact, and material is opened
Beginning spills from gap.As the abrasion of sealing ring inner ring is increased, the gap of former contact surface is increasing, and substantial amounts of material is from abrasion
Spill in the gap for occurring afterwards, cause a large amount of tobacco leaves to be lost in and damage, have a strong impact on production and be normally carried out and work site environments,
Certain economic loss is caused to enterprise.Existing tangent plane is that plane or conical-surface type seal life are short, quick abrasion, more
Difficulty is changed, spare parts consumption is big.
Utility model content
The purpose of this utility model is to provide a kind of new drum-type tobacco leaf moisting machine sealing device, good with elasticity, is used
Life-span length, the advantages of not easy to wear, prevent material and leaks.
The utility model is achieved like this：The sealing device of drum-type tobacco leaf moisting machine, including：Sealing ring, fixing device,
Sealing ring is made using wear-resisting flexible material, and sealing ring has top surface and side wall, and sealing ring tangent plane is in inverted L-type, top surface
It is more than 90 degree with the angle of side wall.When using, the side wall of sealing ring is in flexible dynamic Contact state with the cylinder of tobacco leaf moisting machine, due to
Sealing ring top surface is more than 90 degree with the angle of side wall, and sealing ring can keep being in close contact with cylinder all the time.
In an embodiment, sealing ring is made using abrasive rubber, has the advantages that low cost, wear-resisting.
In an embodiment, sealing ring utilizes particular manufacturing craft, a sulfidization molding, sealing ring section in inverted L-type simultaneously
And non junction, there is low cost, long service life.
The sealing device of drum-type tobacco leaf moisting machine of the present utility model, because sealing ring tangent plane is in inverted L-type, top surface and side
Wall angle is more than 90 degree, and sealing ring can remain flexible sealing, and be in close contact with cylinder.
Description of the drawings
Fig. 1 is the tangent plane schematic diagram of the sealing device use state of drum-type tobacco leaf moisting machine of the present utility model.
Main element symbol description：
1 sealing ring
1a top surfaces
1b sides wall
2 hold-down rings
3 bolts
4 cylinders
5 frames
α seals the angle of top surface of ring and side wall
Specific embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1, the sealing device of drum-type tobacco leaf moisting machine of the present utility model, including：Sealing ring 1, fixing device.This
In embodiment, fixing device includes：Hold-down ring 2, bolt 3.Sealing ring 1 is fixedly mounted in frame 5 by fixing device.
Sealing ring 1 utilizes particular manufacturing craft, and a sulfidization molding is made using wear-resisting flexible material, such as wear-resisting
Rubber, has the advantages that non junction, low cost, wear-resisting.
Sealing ring 1 has top surface 1a and side wall 1b, and the tangent plane of sealing ring 1 is in inverted L-type, between top surface 1a and side wall 1b
With angle α, angle α is more than 90 degree.
When using, the side wall of sealing ring 1 is in flexible dynamic Contact state with the cylinder 4 of tobacco leaf moisting machine, due to sealing ring top surface
It is more than 90 degree with the angle α of side wall, sealing ring side wall can be close to all the time cylinder.No matter cylinder axial float or radial deflection,
Sealing ring side wall all will be tightly attached on cylinder, in flexible dynamic Contact state, be effectively sealed against and be attached to cylinder entry/exit
Fragment on mouth, it is ensured that clean and tidy, the elimination potential safety hazard of production environment, improves production efficiency and product quality.
