Description

Technical Field

[0001] The utility model relates to the technical field of geomembrane production, in particular to a mixing device for geomembrane production. Background Art

[0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and composited with non-woven fabric. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film, mainly polyvinyl chloride (PVC), polyethylene (PE), and EVA (ethylene / vinyl acetate copolymer). They are a kind of polymer chemical flexible material with low specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good antifreeze performance. At present, there is such a problem in the process of using polyethylene to produce geomembranes. Because polyethylene is insoluble in any organic solvent at room temperature, polyethylene needs to be heated and dried before mixing and stirring. In this way, the staff first puts the polyethylene into the drying device for heating and then puts it into the mixing device for mixing and stirring. This repeated work increases the workload and work pressure of the staff. At the same time, it also increases the time required for production during the production process, reducing the production of geomembranes.

[0003] According to a Chinese patent, a mixing device for geomembrane production is disclosed, and its announcement number is: CN217144464U. The patent is simple to operate, compact in structure, and reasonably designed. The air pump draws air between the outer bin and the inner bin through the air inlet pipe, and sends it into the heating bin through the connecting pipe. After being heated by the electric heating wire, it is discharged into the space between the outer bin and the inner bin through the exhaust pipe, thereby increasing the temperature of the air between the outer bin and the inner bin, thereby increasing the temperature in the inner bin and speeding up the mixing work. In this technical solution, when the raw materials are stirred, the heat is conducted through the inner bin, resulting in low heating efficiency of the raw materials in a short time, thereby affecting the mixing efficiency of the geomembrane raw materials. For this reason, we propose a mixing device for geomembrane production. Utility Model Content
