Dispersion machine with airtight structure

Abstract

The invention discloses a dispersion machine with an airtight structure. The dispersion machine comprises a dispersion barrel, a dispersion wheel, a driving motor, a driving main shaft, a bearing seat and a sealing assembly, wherein the sealing assembly comprises a sealing disc, a static ring and a follow-up ring; at least a part of the static ring is arranged in a sealing disc hole of the sealing disc, and the static ring and the sealing disc are in rotation stopping connection; the driving main shaft penetrates through a static ring hole and can rotate relative to the static ring; a static ring air channel comprises a radial air channel extending in the radial direction of an central axis and capable of being in butt joint with an induction through hole, and an axial air channel axially extending along the central axis; the follow-up ring is connected to the driving main shaft in a rotation stopping mode, so the follow-up ring can synchronously rotate along with the driving main shaft; and a plurality of sealing gear rings distributed in the axial direction of the central axis are arranged on the outer side of the follow-up ring. The dispersion machine with the airtight structure has the beneficial effects that the sealing effect of the main shaft can be guaranteed, and meanwhile, heat dissipation of the main shaft can be guaranteed.

AI Technical Summary

Problems solved by technology

[0003] When the high-speed disperser is running, the material will generate a lot of centrifugal force and splash during the high-speed dispersing process. Due to the strong centrifugal force brought by the speed of the high-speed disperser, the material is easy to leak to the transmission part along the gap between the main shaft accessories, thereby affecting the operation of the equipment. bring adverse effects

[0004] In related technologies, a multi-layer sealing structure is used to shield the leakage of materials, but due to the high speed of the driving spindle of the high-speed disperser, contact sealing cannot be performed, and the sealing effect is poor

[0005] In other related technologies, such as the technology recorded in the Chinese patent document CN209370459U, a certain pressure gas is used to achieve the effect of gas sealing, so that a certain sealing effect can be achieved without contacting the driving spindle, but the structure in this technical solution It is designed so that the gas forming the air film seal is relatively static (in order to ensure the corresponding volume to bring sufficient pressure), and when the driving spindle rotates at high speed (tens of thousands of revolutions per minute), the gas will be rubbed to generate heat, which is not conducive to driving the spindle heat dissipation

[0006] At present, there is no dispersing machine that can not only ensure the sealing effect of the main shaft, but also ensure the heat dissipation of the main shaft.
