Example one

As shown in fig. 1-3, the present embodiment provides a flow guide sleeve, which includes a flow guide sleeve body 1, wherein the flow guide sleeve body 1 is provided with a through hole 11 penetrating through two end surfaces thereof, the through hole 11 is used for penetrating through a power shaft 302 of a viscous fluid degassing device, and the periphery of the through hole 11 is provided with a flow blocking wall 12; a diversion trench 13 is arranged on the periphery of the flow blocking wall 12; the bottom of the diversion trench 13 is provided with a diversion hole 14, the height of the diversion baffle wall 12 is higher than that of the diversion trench 13, and the inlet of the diversion trench 13 is used for communicating with a feed inlet 101 of the viscous fluid degassing device. Wherein, the baffle wall 12 is a tubular structure, and the power shaft 302 is rotatably arranged on the inner side wall of the baffle wall 12. Preferably, the power shaft 302 is journaled to the inner sidewall of the baffle wall 12.

In this embodiment, with the above arrangement, the viscous fluid flows into the shed assembly 200 through the diversion holes 14 after entering the diversion trench 13 through the material inlet 101 of the viscous fluid degassing device, so that the viscous fluid is prevented from being stuck to the power shaft 302, and the degassing effect of the viscous fluid is improved. In addition, the baffle wall 12 can fix the power shaft 302, so that the rotation of the power shaft 302 is more stable.

Regarding the structure of the diversion trench 13, in the present embodiment, specifically, the inner diameter of the diversion trench 13 is gradually reduced after being unchanged from top to bottom. The structure enables the feeding port 101 to be far away from the power shaft 302, so that a container for containing viscous fluid in the process of injecting the viscous fluid is prevented from interfering with the power shaft 302, and the convenience of injecting the viscous fluid is improved. In addition, the structure is also beneficial to enabling the diversion holes 14 to be close to the power shaft 302, the surface of the umbrella skirt assembly 200 is utilized as much as possible, the tiled area of the viscous fluid is enlarged as much as possible, and the degassing efficiency of the viscous fluid is improved.

With the arrangement of the above configuration, the flow velocity of the viscous fluid is effectively suppressed, and the viscous fluid flowing out of the guide hole 14 hardly tends to move toward the power shaft 302.

Further, the length of the diversion hole 14 is greater than a predetermined distance. The preset distance is determined according to the viscosity of the fluid, the inclination of the side wall of the diversion trench 13 and the depth of the diversion trench 13, and specifically, it is required to ensure that the viscous fluid flowing downwards through the diversion trench 13 in the diversion hole 14 according to a parabolic line is intercepted by the side wall of the diversion hole 14, so that the viscous fluid is prevented from moving towards the direction of the power shaft 302 after flowing out of the diversion hole 14.
