Abstract

A static mixing device of a trace moulding and extracting material comprises a mixing cavity, a mixing screw rod, and a connection sleeve, and the mixing cavity and mixing screw rod are connected by the connection sleeve. One end of the mixing screw rod is provided with a material inlet and a first joint part. One end of the mixing cavity is provided with a material outlet, and the other end is provided with a second joint part. The shape of the first joint part and the shape of the second joint part match with the shape of the connection sleeve. During the application process, a first component (eg. silicone rubber) and second component (eg. a vulcanizer) of a trace moulding and extracting material are injected into the two openings of the material inlet; the first component and second component are fully mixed when going through the left-rotation blades and the right-rotation blades; then the mixture advances spirally along the spiral direction; during the rotation process, axial shunting is formed, and thus the silicone rubber is fully stirred in the pipeline and completely mixed.

Description

technical field [0001] The invention relates to a mixing device, in particular to a static mixing device, and more particularly to a static mixing device for extracting materials from trace molding. Background technique [0002] The extraction rate of three-dimensional traces such as tool traces left in criminal cases and other scenes is low. The main reason is that there is a lack of extraction methods that are easy to operate and have high dimensional accuracy. In the prior art, silicone rubber, as an important extraction material for three-dimensional trace molding, is widely used in the extraction of three-dimensional traces at crime scenes. However, the most commonly used method in the prior art is manual mixing, which on the one hand increases the complexity of the trace extraction operation and prolongs the time; on the other hand, it will cause uncertainty in the curing time and changes in mechanical properties such as material strength. It directly affects the dime...
