Description

[Detailed description of the invention] This invention is an arcuate baffle plate with two types of strings, long and short, which is applied to a static in-tube mixer for liquids.
The present invention relates to a modification of a known mixing element consisting of a fle plate (hereinafter simply referred to as arcuate plate).

The purpose of this is when the liquid to be mixed consisting of two or more types is a particularly viscous liquid or a colloidal solution, and when coarse grained or gel-like condensates or fibrous contaminants are mixed therein, In the process of flowing through the pipe of the mixer, deflocculation and dispersion of the coagulated material into the liquid, and defibration and diffusion of the entangled fibrous contaminants into the liquid are automatically carried out. The object of the present invention is to provide a mixing element capable of obtaining a homogeneous mixed liquid.

The details of the mixing element according to this invention will be explained below with reference to drawings showing respective embodiments, while comparing with mixing elements of known structures.

Fig. 1 is a front view of the mixing element that appears when half of the pipe wall of the mixer containing a built-in mixing element of a known structure is vertically cut away, Fig. 2 is a back view of the mixing element, and Fig. 3 is a partially cut away view of the mixing element. As shown in the respective perspective views, the mixing element inserted and fixed into a tube body 3 having an inlet 1 for the liquid to be mixed and an outlet 2 for the mixed liquid is aligned with an axis 4 parallel to the flow direction of the liquid to be mixed. The string consists of two types of bow-shaped plates, long and short, fixed in layers.

At this time, on one side of the shaft 4, each string 6 (a plurality of short strings) of arcuate plates 5 (a plurality) of short strings, which are inclined at approximately 40 degrees with respect to the shaft 4 and parallel to each other at regular intervals, are attached. (see Figure 3) is fixed at the center to the shaft 4, and at each end of the adjacent short-string bow-shaped plate 5 on the opposite side in the direction of the axis 4, there is a long-chord bow-shaped plate γ inclined at approximately 60 degrees with respect to the axis 4. (Both ends of a plurality of 9 are joined together to form an integrated joint 8, and the center of the string 9 of the long chord bow plate 7 is fixed to the shaft 4 to form a double laminated layer consisting of long and short chord bow plates. is composed of

On the other hand, on the opposite side or behind this double stack with respect to the axis 4 (see FIG. 2), it intersects the arcuate plates 5 of said short chords and is inclined at approximately 40 degrees to the axis 4, and said The center of each string 6 (see FIG. 3) of the short string bow plates 5 (see FIG. 3), which are parallel to each other at approximately the same interval as the parallel short string bow plates 50, is connected to each string of the long string bow plates 1. It consists of a monolithic laminate consisting only of short chord arcuate plates 5, which are fixed to the shaft 4 on the opposite side to which the plate 9 is fixed.

The known mixing element has the above-mentioned structure, and a large number of large and small, wide and narrow gaps, so to speak, windows are formed between the axis and the long and short chord arcuate plates.

Therefore, if the liquid to be mixed has a relatively low viscosity and does not contain coarse particles or fibrous impurities, it flows through the many windows in a zigzag manner while colliding with each of the long and short chord arcuate plates. The desired homogeneous mixed liquid can be easily obtained by the liquid stirring action of the turbulent flow that automatically occurs during the process.

However, if coarse particles or gel-like condensates or fibrous contaminants are mixed in a liquid to be mixed consisting of two or more types such as a high viscosity liquid or a colloidal solution, these condensates or contaminants may be mixed with known mixtures. The crack formed in the joint 8 of the element is a sharp gap like an eye (
The window) 10 is clogged and accumulates on top of it one after another, making this gap even more narrow, which obstructs the flow of the liquid to be mixed, and at the same time, the coagulated substances and Experience has shown that it makes it impossible to deflocculate, defibrate, disperse, diffuse, etc., all of the impurities, making it impossible to achieve the purpose of mixing.

This invention was made in order to eliminate such inconveniences, and is essentially a modification of the known mixing element to a mixing element having a structure in which the sharp window 10 as described above is removed.

That is, as shown in FIG. 4, FIG. 5, and FIG. 6, 120 strings of the tipless bow-shaped plate 11 in which the tip of the bow-shaped plate 7 of the long string bow-shaped plate 7 is cut off in the known mixing element. The tip surfaces 13, 13' are joined to the chords 6' of the short chord arcuate plates 5' behind the axis 4, and
The center of this string 12 was fixed to the shaft 4 while being inclined at approximately 60 degrees with respect to the shaft 4, and a double laminate was constructed by comprising a short string bow plate 5' and a tipless bow plate 5''.

By partially modifying a known mixing element, the sharp gap 10 can be eliminated, and the mixing element can be mixed with two or more types of highly viscous liquids or colloidal solutions containing condensates and impurities as described above. They succeeded in effectively and easily mixing the liquids to be mixed.
