Principle of work:
Elder generation is material suspended in liquor with preliminary fragmentation, relies on to have high-tension apparatus generation high velocity liquid stream now.High velocity liquid stream produces resonance through resonatron, and liquid stream jet velocity further improves, and two strands of high velocity liquid streams are done buffering slightly in buffer tube, and oppressed entering rapidly forms two strands of high velocity liquid streams and sharp impacts in impact tube in the tiny isocon of diameter again.Produce a series of effects such as high speed shear effect, cavitation, vibration and oscillation effect, vortex effect, expanded effect, instantaneous temperature and instantaneous pressure drop in the working process, thus the material particles in the suspension is further broken.
Suspension liquid enters the feed-pipe of the impact cavity that is used for cell wall breaking under the high-pressure pump effect, cylindrical cavity is arranged as resonatron at the impact cavity that is used for cell wall breaking, this helps producing the self-vibration pulsing jet, it is right that fluidic disturbance frequency and chamber natural frequency are complementary, motive fluid resonance produces big amplitude, high-frequency oscillating pressure.After fluid is divided into two strands of high velocity liquid streams, because its powerful longitudinal velocity difference causes huge shearing action.When two bursts of positive collisions of identical high-velocity fluid, fluid loses the speed on the original flow direction suddenly, produces huge Impact energy.Bump against strongly between the solid particulate in the fluid.Simultaneously, fall, can form the effect of intensive vortex at impingement region because the huge pressure of generation is bumped against in the flow field.The bump and the friction of strong horizontal direction appears in fluid, and the particle in the fluid is laterally bump and friction of experience again behind vertical bump.Along with clarifixator ram pump output rating increases, fluid obtains big more momentum and clashes into.Except that the effect of vertical direction and horizontal direction, the vortex effect of other all directions all has different bump of degree and friction.Fluid bumps against the back huge pressure of generation and falls, and occurs cavitation when pressure is lower than the vapour pressure of liquid.When the increase along with the time and intensity of cavitation, the power that cavitation erosion produces also is indubitable, and its huge energy is then more to be married again around in the flow field, thereby stream field produces the destruction bigger than flow field in the valve homogenizer spool.
For the impact cavity that is used for cell wall breaking, it is mainly combined by binary master chamber and the secondary chamber of monobasic.Use the shell-broken effect in the secondary chamber of binary master chamber or monobasic not as binary master chamber and the secondary chamber of monobasic effect of Combination separately.
The invention has the advantages that: adopt the combination, particularly binary main resonance pipe in the secondary chamber of binary master chamber or monobasic, tiny bifilar isocon, tiny structures such as secondary jet pipe, allow high velocity liquid flow sharp impacts.Produce a series of effects such as high speed shear effect, cavitation, vibration and oscillation effect, vortex effect, expanded effect, instantaneous temperature and instantaneous pressure drop in the working process, thereby the further fragmentation of the cell walls of the material in the suspension is obtained fine debris.More complete cell wall breaking is very difficult, and adopting binary main resonance pipe is for the resonance through twice obtains more high speed liquid stream, helps more complete cell wall breaking after more high speed liquid stream brute force clashes.
For example for Ganoderma spore powder, under same processing condition: use binary master chamber separately, use the shell-broken effect in the secondary chamber of monobasic to be respectively 70.2%, 75.2% separately.The shell-broken effect of the two-chamber combination that the secondary feed-pipe in the main discharge nozzle in binary master chamber and the secondary chamber of monobasic is connected can reach 94.6%, and the shell-broken effect of the two-chamber combination that the secondary discharge nozzle in the secondary chamber of monobasic and the main feed-pipe in binary master chamber are connected can reach 96.2%.
