The disc type centrifugal machine is a purifying and separating machine, which utilizes the principle that the mixed liquid has different densities and mutually incompatible light and heavy liquid phases and solid phases have different sedimentation speeds under the action of centrifugal force to achieve the purposes of separating and layering or settling solid particles.
The bottom of the feeding pipe of the existing disc type centrifuge is not treated, the mixed liquid enters the inner space of the disc through the neutral hole in an axial entering mode, the heavy phase is thrown to the outer edge of the rotary drum body under the action of centrifugal force and flows out along the fixed flow passage, the light phase flows along the inward radial direction of the disc, kinetic energy is converted into pressure potential energy through the radial pump, and finally the pressure potential energy flows out of the light phase outlet.
When the mixed liquid enters the rotary drum body from the feeding pipe in an axial speed mode, the mixed liquid finally enters the disc inner space for separation under the flow guiding effect of the wall surface of the rotary drum body.
For the related art, the inventors consider that the separator does not accelerate the fluid circumferentially before entering the disc, but the disc rotates at a high speed with a relatively high rotation speed (typically 5000-10000 rpm), and the difference between the two causes the fluid to be greatly sheared, so that the fluid drops are easily broken and emulsified, and further the local instability is increased, the stable interface inside the flow channel is damaged, and finally the separation efficiency is reduced, especially for the working condition with high separation precision requirement, the influence is relatively large, and the separation index may not reach the standard.
