The dynamic water pipe and the static water pipe do not theoretically need to swing relatively, but the reason that the spherical part is matched with the spherical cavity is still set is as follows: 1. the relative axial movement of the dynamic water pipe and the static water pipe is avoided; 2. the vibration generated when the water-cooling screw conveyor works and the deformation of parts after long-term work can cause the dynamic water pipe and the static water pipe to generate small relative swing.
The shape of spherical portion and spherical chamber has decided that the sealed degree of difficulty of sealing member realization two is bigger relatively, and vibration and atress and fluid pressure's influence during operation lead to first seal structure to be effective easily, lead to leaking, influence material cooling effect, also make water-cooling screw conveyer maintenance frequency higher.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: provided is a sealing structure of a water-cooled screw conveyor, which has higher reliability.
The technical scheme adopted for solving the problems is as follows: the sealing structure of the water-cooling screw conveyor comprises a static water pipe and a dynamic water pipe, the static water pipe comprises a spherical part, the end part of the dynamic water pipe is provided with a spherical cavity, the spherical part is positioned in the spherical cavity and the spherical cavity are matched, a first sealing structure is arranged between the spherical part and the spherical cavity, the static water pipe further comprises an extension pipe, the extension pipe is positioned in the dynamic water pipe and is connected with the spherical part, and a second sealing structure is arranged between the extension pipe and the dynamic water pipe.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 2 and 3, the sealing structure of the water-cooling screw conveyor comprises a static water pipe 1 and a dynamic water pipe 2, the static water pipe 1 comprises a spherical part 11, the end part of the dynamic water pipe 2 is provided with a spherical cavity 21, the spherical part 11 is positioned in the spherical cavity 21 and matched with the spherical cavity 21, a first sealing structure 3 is arranged between the spherical part 11 and the spherical cavity 21, the static water pipe 1 further comprises an extension pipe 12, the extension pipe 12 is positioned in the dynamic water pipe 2 and connected with the spherical part 11, and a second sealing structure 4 is arranged between the extension pipe 12 and the dynamic water pipe 2.
An extension pipe 12 is additionally arranged on the static water pipe 1, and a second sealing structure 4 is arranged between the extension pipe 12 and the dynamic water pipe 2. Therefore, the sealing structures between the static water pipe 1 and the dynamic water pipe 2 are increased from one to two, and the sealing effect is improved, and the other sealing structure continues to play a role in keeping the sealing effect even if one sealing structure is damaged. Moreover, the two sealing structures bear the force together, the stress of a single sealing structure is reduced, and the probability of damage is reduced. Furthermore, the second sealing structure 4 is simpler and relatively more reliable than the first sealing structure 3.
The extension pipe 12 and the second sealing structure 4 have the function of resisting the relative swing of the dynamic water pipe 2 and the static water pipe 1, and have certain adverse effects. However, because the relative swing of the dynamic water pipe 2 and the static water pipe 1 is very small, the reasonable arrangement of the extension pipe 12 and the second sealing structure 4 can greatly reduce the resistance effect, thereby avoiding generating adverse effects.
For example, as shown in fig. 2, the extension pipe 12 includes an outer flange 121, the outer flange 121 is spaced apart from the dynamic water pipe 2, and the second sealing structure 4 is mounted on the outer flange 121. In this case, the extension pipe 12 should be short to reduce the swing amount, the distance between the outer flange 121 and the dynamic water pipe 2 should be suitable to avoid the contact between the two, and the width of the outer flange 121 and the second sealing structure 4 should be small to avoid the influence on the swing. The second sealing structure 4 can be an O-shaped rotary sealing ring which is a rotary sealing ring consisting of a slip ring made of filled polytetrafluoroethylene and an O-shaped ring for providing elasticity.
As shown in fig. 3, the extension pipe 12 may include an extension pipe main body 122 and a bellows 123, the bellows 123 may be connected to the spherical portion 11, the extension pipe main body 122 may be connected to the bellows 123, and the second sealing structure 4 may be mounted on the extension pipe main body 122. The bellows 123 is flexible to allow the extension pipe 12 to swing to accommodate relative swinging of the dynamic water pipe 2 and the static water pipe 1. In this case, the width of the second seal structure 4 may be large, and a packing seal structure with low cost may be selected.
