Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline static mixing equipment, in particular to a pipeline static mixer. Background Art
[0002] A static mixer is a common mixing device, mainly used to mix two or more liquids evenly. It usually consists of one or more static mixer blades, which are connected together in a spiral or star shape. Its basic working mechanism is to use the mixing unit fixed in the tube to change the flow state of the fluid in the tube to achieve good dispersion and sufficient mixing between different fluids. Static mixers can be used to prepare various mixtures, such as coatings, paints, cosmetics, medicines, etc.
[0003] The internal structure of the existing static mixer is a cross-welded structure. After the material enters, there are dead corners at the welding points, which can easily lead to poor material flow, thereby easily causing dead material on the surface of the product and unstable extrusion. The cross-welded static internal structure is prone to structural collapse and damage due to long-term use of the welding points and excessive pressure, affecting the material yield. In addition, when heating, the existing static mixer only pours oil into the outer interlayer, resulting in poor heating effect, which affects the processing efficiency of the material.

[0024] One end of the four oil inlet pipelines 5 away from the outer sleeve 1 is fixedly provided with a filtering device 9 for filtering impurities and particulate matter, a first connecting column 10 and a second connecting column 11 are further arranged in the inner sleeve 2, two ends of the first connecting column 10 are respectively communicated with the interiors of the two first interlayers 3, two ends of the second connecting column 11 are respectively communicated with the interiors of the two second interlayers 4, the first connecting column 10 and the second connecting column 11 are hollow structures, the calibers of the first connecting column 10 and the second connecting column 11 are larger than that of the connecting pipeline 6, rubber cushions 12 are fixedly arranged on the sides of the first connecting pipe 7 and the second connecting pipe 8 close to the inner sleeve 2, detection holes 13 for detecting the internal pressure are arranged at both ends of the inner sleeve 2, the rubber cushions 12 arranged on one side of the first connecting pipe 7 and the second connecting pipe 8 prevent materials from flowing out along the gap during installation, thereby enhancing the sealing performance of the pipeline, the filtering device 9 arranged at one end of the four oil inlet pipelines 5 filters impurities and particulate matter in the oil, thereby preventing the connecting pipeline 6 from being blocked by too many particulate matters and affecting the heating efficiency, and because the calibers of the first connecting column 10 and the second connecting column 11 arranged in the inner sleeve 2 are larger than that of the connecting pipeline 6, the materials can be better mixed when passing through.
[0025] The working principle of the utility model is as follows: when the mixture in the inner sleeve pipe 2 needs to be heated, the oil is transmitted to the two first interlayers 3 and the two second interlayers 4 of the outer sleeve pipe 1 and the inner sleeve pipe 2 through the four oil inlet pipes 5 arranged on the surface of the outer sleeve pipe 1, and the oil flows in the inner sleeve pipe 2 through the plurality of connecting pipes 6; because the plurality of connecting pipes 6 are staggered arranged in the inner sleeve pipe 2, when the oil enters the connecting pipes 6, the oil reaches the center of the mixture, so that the mixture can be heated better; when the material enters the inner sleeve pipe 2, the flow state of the two materials is changed constantly through the plurality of staggered connecting pipes 6, so that the two materials are mixed; because the connecting pipes 6 in the inner sleeve pipe 2 are all circular pipe structures, there is no dead angle welding point, so the problem of material flow not smooth caused by the dead angle does not occur; the pressure when the material enters and exits the inner sleeve pipe 2 can be detected through the detection holes 13 arranged at the two ends of the inner sleeve pipe 2, so that the pressure difference when the material enters and exits the inner sleeve pipe 2 can be calculated conveniently by the staff.
