Abstract
The utility model relates to a slotting type static mixing tube. A static mixer is widely applied to industries such as water treatment industries, chemical industries, oil industries and environmental protection industries. The slotting type static mixing tube comprises a tube body and a spiral blade, wherein the spiral blade is arranged in the tube body, and the spiral blade and the tube body are coaxially arranged. The spiral blade is formed by twisting a rectangle metal sheet along a center line, the width H of the rectangle metal sheet is the same with the diameter of the tube body, the torsional angle is 180 degrees, and a left spiral blade and a right spiral blade are arranged in the tube in a staggering way with 90 degrees. The rectangle metal sheet is provided with slits with the width of h symmetrically along the center line, and the ratio of h to H is equal to 0.1-0.6. On the basis of the traditional mixing tube, the spiral blade is divided into two, a gap is left between the two spiral blades, and the quantity of vortex and the intensity are larger than that of the traditional static mixing tube.
Description
Technical field
The utility model relates to a kind of split static mixing tube.
Background technology
In the coagulating treatment process of former water, can coagulation effect and flocculant spread rapidly in water confidential relation, and the quality of coagulation effect directly influences effluent quality.In China's water treatment field, often use static mixer to strengthen mixing, to reach the purpose of enhanced coagulation.Static mixer is morning, widely used a kind of tubular static mixer to occur.Except water treatment field, it all is widely used in industries such as chemical industry, oil, environmental protection.The hybrid element of traditional static mixer is the helical blade of 180 ° of torsional angles, and left-handed, dextrorotation blade staggers in pipe 90 ° and alternately arranges.As Fig. 1, be provided with helical blade 1-2 among the pipe 1-1.Rotate, twist, cut apart because the adding of helical blade, tube fluid produce in the engineering that flows, mixed performance is strengthened.
Summary of the invention
The purpose of this utility model provides a kind of novel split static mixing tube.
The utility model comprises body and helical blade, and helical blade is arranged in the body, and helical blade and the coaxial setting of body.
Described helical blade is that a rectangular metal sheet forms along center line is twisted, and the width H of rectangular metal sheet is identical with the diameter of body, and torsional angle is 180 °, and left-handed, dextrorotation blade staggers in pipe 90 ° and alternately arranges.Described rectangular metal sheet has the slit that width is h, h:H=0.1～0.6:1 along the center line symmetry.
In the hybrid technique process, vortex diffusion, molecular diffusion exist simultaneously.Because molecular diffusion speed is much larger than the vortex diffusion velocity, vortex diffusion couple incorporation time plays a leading role.Turbulent flow can regard that eddying motion by the different scale varying strength constitutes as, and turbulence intensity increases, and can improve the mixed performance of blender effectively.The utility model is divided into two helical blade on the basis of traditional type hybrid element, leaves the gap in the centre, and vortex quantity and intensity are all greater than the traditional type blender.Mixed effect is better than the conventional hybrid device, its within the specific limits flow resistance also be lower than the traditional type blender.
Description of drawings
Fig. 1 is the structural representation of traditional static mixing tube;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the expansion planar structure schematic diagram of helical blade in the utility model.
The specific embodiment
As shown in Figure 2, a kind of split static mixing tube comprises body 2-1 and helical blade 2-2, and helical blade 2-2 is arranged in the body 2-1, and helical blade 2-2 and the coaxial setting of body 2-1.
Helical blade 2-2 is that a rectangular metal sheet forms along center line is twisted, and the width H of rectangular metal sheet is identical with the diameter of body 2-1, and torsional angle is 180 °, and left-handed, dextrorotation blade staggers in pipe 90 ° and alternately arranges.As shown in Figure 3, rectangular metal sheet has the slit 2-3 that width is h, h:H=0.1～0.6:1 along the center line symmetry.Like this, the twisted back of rectangular metal sheet forms two helical blades (dotted line among Fig. 2 and chain line are represented two helical blades respectively), has the space between two helical blades.
Claims (1)
