Abstract

A novel high-strength micro-turbulence tube comprises at least two internal tube segments with the diameter gradually increasing. At least two round expanded tube segments are disposed on the inner wall of the tube segment with largest diameter. Flowing speed and direction of pulp along the inner sections of the expanded tube segments changes many times after the sectional area of the tube decreases and increases many times, inner fiber of the pulp is provided with disperse energy, good dispersing effect is obtained, consumption of raw materials is saved, and pumping energy consumption is decreased.

Description

Novel high-strength microturbulencd pipe

Technical field

The invention belongs to the turbulent pipe that turbulent pipe technical field of structures, especially papermaking-method reconstituted tobaccos in flow box are produced flow box used.

Background technique

In papermaking-method reconstituted tobaccos production technology, flow box is dispersed for the mixing material that the liquid such as paper making pulp or other fibers and water are mixed, and homodisperse slurry is arranged on filter screen.Because fluid is when being flow to filter screen and be shaped by pipeline from pump, the fiber in slurry has the poly-trend of wadding, and this wadding is poly-very fast and be very easy to, slurry concentration is higher, wadding is poly-also strong, and flow velocity is faster, and wadding is poly-also stronger, thereby must allow slurry pass through flow box time, device in flow box gives slurry fluid high-strength turbulence, in increasing to fluid can, allow fiber turbulence in very little scope, prevent that fleeces is poly-, in fluid, be uniformly dispersed.Traditional device is that the hole roller by rotating is that distributor roll rotates in fluid, allows fluid agitation, disperses.The result that this stirring brings is that slurry produces whirlpool on a large scale, makes slurry stream unstable, produces inhomogeneous on a large scale.Ye You producer adopts turbulent pipe to allow slurry produce turbulence, but traditional turbulent pipe just makes with pipe three grades of hierarchic structures that internal diameter increases step by step, by three grades of ladders, allows slurry produce turbulence.But this turbulence intensity is low, be conventionally only applicable to the dispersion of the fluid that concentration is lower, viscosity is lower, for the sugary height of slurry and the large papermaking-method reconstituted tobaccos slurry of viscosity, dispersion effect is undesirable.

Summary of the invention

The deficiency that object of the present invention exists in order to solve above-mentioned prior art just, provides a kind of turbulence intensity large, can be applicable to compared with high viscosity and concentration fluid dispersion, is specially adapted to the high-strength microturbulencd device that papermaking-method reconstituted tobaccos production headbox stock is disperseed.

Object of the present invention is achieved through the following technical solutions.

Novel high-strength microturbulencd pipe, the inner at least two-stage pipeline section increasing step by step for caliber of turbulent pipe, is provided with at least two pitch circle shape expanders at the pipeline section inwall of caliber maximum.

The present invention is provided with 3~6 pitch circle shape expanders at the pipeline section inwall of caliber maximum.The inner triode section increasing step by step for caliber of turbulent pipe.

Adopt the present invention, slurry enters the multistage pipeline section that caliber increases step by step, pulp flow speed is reduced step by step, pass through multi-stage circular expander, slurry is through the long-pending increase of pipeline section repeatedly and dwindle conversion again, in scalable pipeline section along cross-wise direction flow velocity with flow to constantly and repeatedly change, make slurry internal fiber obtain energy dispersive, the dispersion effect having obtained, and can economize in raw materials and expend, pumping energy consumption reduced.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

As shown in Figure 1, the inner at least two-stage pipeline section increasing step by step for caliber of turbulent pipe of the present invention, the present embodiment is provided with triode section 1,2,3, afterbody pipeline section inwall in caliber maximum is provided with at least two pitch circle shape expanders, circular expander can arrange 3~6 joints conventionally, and the present embodiment is provided with three pitch circle shape expanders 4,5,6.

Fluid as paper making pulp from left to right direction enter in turbulent pipe, the first order pipeline section of turbulent pipe 1 aperture is minimum, now fluid-flow rate is maximum, fluid is in turbulent.While entering first order pipeline section 2, because pipeline section aperture ratio first order pipeline section aperture, the second level increases, after fluid enters second level pipeline section, flow velocity reduces, and forms the micro-whirlpool of fluid at ladder place, and segment fluid flow flow direction changes, and produces the power disperseing; In like manner, fluid enters the rear flow velocity of third level pipeline section 3 further to be reduced, and further produces disperse power.Afterwards, fluid enters more piece expansion-contraction pipe, liquid speed reduces again, when through three pitch circle shape expanders 4,5,6 place, because the sectional area of pipe dwindles after repeatedly increasing, fluid alternately expands and the velocity in pipes and the flow direction that dwindle constantly repeatedly change at this section of sectional area, in cross-wise direction, flow velocity and flow direction annular change, and internal fluid fiber obtains energy dispersive, is disperseed preferably.

This high-strength microturbulencd device adopts static cell, and the part that do not turn round is applicable to slurry and the fluid dispersion of higher concentration.Because dispersion effect is good, can reduce the consumption of slurry and the power consumption of pumping fluid, energy-conserving and environment-protective, and safeguard simply long service life.
