Problems solved by technology

The structure of other types of mixing elements (SMV, SMK, SMXL, ISG, IS50, SMR, screw) is relatively complicated. Although the mixing effect is good, the pressure drop during the mixing process is large, and for higher concentration, higher viscosity or Fibrous fluids are prone to clogging during the mixing process; among them, IS50 type spiral structure, complex processing, easy clogging, etc. are more obvious
[0013] The common deficiencies that the above ten types of static mixers have are: one, various mixing elements for fluids such as pulp fibers are easy to hang slurry on the inflow direction of the slurry fi

Example Embodiment

[0047] Example 1:

[0048] Depend on figure 2 and image 3 It can be seen that the basic unit section consists of a circular tube and three triangular tube wall blades welded on its inner wall. The solid line part in the figure is the blade, and the dotted line or dot-dash line part is the circular tube; the right figure is the axonometric view of the left figure (viewed from right to left).

[0049] For the production of leaves, see Figure 4 , the material of each blade is taken from the circumscribed circular tube; when making, take a section of circular tube (determine the tube height according to the design size of the blade), and cut it on the tube wall according to the dotted line to form a vertical plane 3; The arc surface 4 is formed by scribe cutting (the arc surface 4 is kept perpendicular to the cylinder wall surface), and the bottom surface 5 is formed by keeping it perpendicular to the axis. The length of the bottom surface depends on the designed blade angle...

[0053] Example 2:

[0054] In the process of engineering design and specific implementation, the following aspects should be grasped:

[0055] (1) The static mixer created by the present invention is based on the basic unit section in use, and flanges are machined at both ends of each (or every two) unit section, and each (or each group) mixing unit is connected by flanges, The blade rotation of adjacent unit nodes or adjacent mixing units can be changed to reverse stagger.

[0056] (2) Determine the size of the blade according to the characteristics and concentration of the main fluid material to be mixed, as well as the type and mixing amount of the external material. leaf size Figure 5 In "the length of the vertical surface 3 and the arc length of the arc surface 5", the ratio of the two lengths determines the "length of the surface 4" and "the angle formed by the surface 4 and the surface 3" (also used in the blade manufacturing process). is called the cutting angle α)...

[0059] Example 3

[0060] Experimental device: In order to determine the effect of the static mixer created by the present invention through experiments, such as Figure 15 experimental device. Figure 4 is the static mixer unit under test, and each mixer uses 2 unit sections. 1 is a stainless steel water tank; 2 is a small medium and thick slurry pump; 3 is a flow meter; 5 is a valve; 6 is a pressure gauge. It mainly measures the pressure drop, flow rate change and distribution and slurry hanging of the fluid material passing through the mixing unit. There are two types of static mixer units to be tested, one is a mixer with 2 unit sections created by the present invention; the other is a standard static mixer - Kenics static mixer with 2 sets of mixing unit elements. The material is plexiglass, customized processing.

[0061] The purpose of the experiment is to compare the pressure, flow rate change and distribution of the two mixers and the situation of hanging pulp.

Abstract

The invention discloses a triangular pipe wall blade type static mixer.The triangular pipe wall blade type static mixer comprises a unit section cylinder and blades fixedly installed on the inner wall of the cylinder.The blades are triangular pipe wall blades formed by cutting the cylinder, and the three triangular pipe wall blades are evenly distributed on the inner wall at 120 degrees and are used for separating fluid materials into three rough incompletely-cutoff zones.The triangular pipe wall blade type static mixer is good in mixing effect, easy to manufacture, capable of saving energy, not likely to hook fiber fluid materials and convenient to clean.

Description

technical field [0001] The invention relates to a static mixer, in particular to a triangular tube wall blade type static mixer. Background technique [0002] Background: In many industrial production and related fields, such as process production and wastewater treatment with fluid materials as processing objects, in addition to the main fluid materials, auxiliary materials and other chemicals must be added. With the continuous improvement of product variety and quality performance requirements in various industries and the development of science and technology, there are more and more auxiliary additives in terms of quantity and type. Therefore, some kind of mixing device or equipment must be used to realize the mixing of liquid-liquid, gas-liquid and other multiphase flows. In industrial production, the equipment that uses the turbulent mixing mechanism to realize these multiphase flow mixing mainly includes mechanical stirring mixing reactors, jet mixers, jet mixers, im...
