Abstract
A kind of compound sealing structure with air seal of paddle-dryer disclosed by the utility model includes drying machine sealing cup dolly, seal chamber, circular cover, seals.The sealing cup dolly can be directly with drying machine end plate soldering, and seal chamber connect with sealing cup dolly, and inside seal chamber, first plus 3-5 encloses sealing material, is then placed in seals, then plus 3-5 circle sealing material, finally compressed with circular cover.The problem of the utility model provides a kind of compound sealing structure with air seal of paddle-dryer, is able to solve paddle-dryer vacuum sealing, to promote the development of special material and vacuum paddle-dryer.
Description
Technical field
The utility model relates to paddle-dryer technical fields, are particularly suitable for the shaft head seal of paddle-dryer
A kind of compound sealing structure with air seal of paddle-dryer.
Background technique
The sealing structure of spindle nose directly affects the operation of drying machine, and traditional sealing structure is by circular sealed base
Whole airtight and watertight padding cavity and its gland is added to constitute.This sealing structure can only seal the blade of the ordinary material under normal pressure
Formula drying machine, if the material dried can not ingress of air, this sealing structure is not much of that.Due to oar blade type
Application and the development of the evacuation of drying machine, the sealing effect of shaft head seal filler just directly affect oar blade type vacuum drier
Development.
Summary of the invention
To overcome the shortcomings of existing structure, the utility model provide a kind of paddle-dryer with the compound of air seal
Sealing structure, the problem of being able to solve paddle-dryer vacuum sealing, to promote special material and vacuum Paddle Drying
The development of machine.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of compound sealing structure with air seal of paddle-dryer, include drying machine sealing cup dolly,
Seal chamber, circular cover, seals；The sealing cup dolly is directly connect with drying machine end plate soldering, seal chamber with
Cup dolly connection is sealed, 3-5 circle sealing material, seals, 3-5 circle sealing material are sequentially provided with inside seal chamber
Material, sealing accent are compressed by circular cover and are connected.
Due to the adoption of the above technical scheme, the specific advantage of the utility model is as follows:
1. material sealing is tighter；
2. air seal can guarantee that special material is not contacted with air；
3. guaranteeing the vacuum degree of vacuum drier.
Detailed description of the invention
Fig. 1 is the schematic diagram of compound sealing structure of the paddle-dryer with air seal；
Fig. 2 is Fig. 1 to cross-sectional view；
In figure: sealing cup dolly 1, seal chamber 2, circular cover 3, seals 4, end plate 5, sealing material 6, spindle nose
7。
Specific embodiment
As shown in Figure 1, 2, the compound sealing structure with air seal of a kind of paddle-dryer includes dry secret
Seal cup dolly 1, seal chamber 2, circular cover 3, seals 4；The sealing cup dolly 1 directly with drying machine end plate 5
Soldering connection, seal chamber 2 are connect with sealing cup dolly 1, and 3-5 circle sealing material 6, gas are sequentially provided with inside seal chamber 2
Body sealing element 4,3-5 enclose sealing material 6, and 2 mouthfuls of seal chamber compress connection by circular cover 3.I.e. inside seal chamber 2, first plus
3-5 encloses sealing material 6, is then placed in seals 4, then plus 3-5 enclose sealing material 6, be finally with the compression of circular cover 3
It can.
The utility model air seal can guarantee that special material is not contacted with air；Keep material sealing tighter；It protects
Demonstrate,prove the vacuum degree of vacuum drier.
