Example Embodiment

[0066] Example 1:

[0067] Method of manufacturing soft elastic container and mixing experiment (1)

[0068] (1) Preparation of mold: prepare two semi-circular plexiglass tubes (outer diameter 7cm, inner diameter 6cm, height 25cm), prepare a hollow plexiglass tube (outer diameter 5cm, inner diameter 4cm, height 30cm) as the inner tube, use The clamp (diameter 7cm) fixes the two semicircular tubes as the outer tube, and then fix the inner tube and the outer tube with screws. The bottom of the inner tube is higher than the bottom of the outer tube, and the bottom of the inner tube and the outer tube are sealed with glass plates ;

[0069] (2) Preparation of soft elastic container: mix liquid silica gel and crosslinking agent at a mass ratio of 10:1, defoam, and pour it into the mold obtained in step (1), and cure for 24 hours to make a soft elastic container. The outer diameter is 6cm, the inner diameter is 5cm, the height is 12cm, the tensile strength (kgf / c㎡) of the soft elasti...

Example Embodiment

[0073] Example 2

[0074] Method of manufacturing soft elastic container and mixing experiment (2)

[0075] Steps (1) to (3) are the same as in Example 1;

[0076] (4) Insert a baffle in the middle of the soft elastic container;

[0077] (5) Same as step (4) in Example 1;

[0078] (6) Mixing effect (see attached figure 2 ): After adding the T-shaped baffle, the uniformity of the overall fluid flow is increased, and no more characteristic flow is found. After 60s, half of the reactor is covered with red, and an irregular ellipse appears in the middle of the two baffles. Flow, the fluid in the container can achieve a good mixing effect after 300s. The mixing efficiency of the soft elastic container is greatly improved after the baffle is added, but a small undesirable mixing zone appears in the lower left corner of the soft elastic container.

Example Embodiment

[0079] Example 3

[0080] Method of manufacturing soft elastic container and mixing experiment (3)

[0081] Steps (1) to (3) are the same as in Example 1;

[0082] (4) Adjust the motor frequency to 100 times per minute;

[0083] (5) Same as step (4) in Example 1;

[0084] (6) Mixing effect (see attached Figure 4 ): Under high-frequency squeezing, the flow speed of the fluid in the soft elastic container increases as a whole, and the flow details become difficult to capture. At 15s, a part of the fluid can be observed flowing from top to bottom, and at 30s, it appears in the upper part of the soft elastic container. Some irregular flow, irregular annular flow appeared in the middle of the soft elastic container to the right, and no obvious mixing was found on the left half. From 90s to 210s, the fluid expanded to the left and the lower part. A good mixing effect was achieved in 240s.

Abstract

The invention relates to a material mixing method and device, a manufacturing method of a soft-elastic container in the device and a material mixing method based on the device; according to the material mixing method, mixing of container internal materials is achieved outside an extrusion container; the device achieving material mixing includes a reciprocating motion device and the soft-elastic container; the manufacturing method of the soft-elastic container includes a mold preparation step and a liquid silicone rubber casting step; the mixing method based on the device includes fixing the soft-elastic container and extruding the soft-elastic container. A stirring blade is not required to be put in a reactor; through extruding the soft-elastic reactor, self elastic deformation of the soft-elastic container is utilized to promote the materials to flow; in the process of original shape restoring of the container, the materials flow again, an extrusion head performs cyclic extrusion, ultimately, the effect of uniform mixing of the materials is achieved, and the stirring blade is avoided from destroying structures of some materials during the mixing process.

Description

technical field [0001] The invention relates to a material mixing method and device, a method for making a soft elastic container in the device, and a material mixing method based on the device, belonging to the field of material mixing. At least one fluid material flows to achieve a uniform mixing effect. Background technique [0002] As a basic unit in industrial production, agitators and reactors are widely used in chemical, pharmaceutical, food, coating and other industries. However, none of the stirrers is universal. Conventional stirring devices usually use a motor to drive the paddles to rotate at high speed, relying on the strong shear force of the paddles to promote the mixing of fluids. However, in cell culture experiments, good mixing is required and cells are not expected to be damaged by shear forces. Also in some food industries, it is necessary to add some solid particles to some foods to increase nutrition and taste, but it is not expected that these parti...
