Vacuumizing mixing machine

Abstract

The invention relates to the technical field of chemical-material mixing equipment and particularly relates to a vacuumizing mixing machine. The vacuumizing mixing machine comprises a rack, wherein the lower part of the rack is provided with a mixing chamber; the upper part of the rack is provided with a pressing device; the mixing chamber is connected with a mixing device; a vacuumizing device for vacuumizing the mixing chamber is arranged above the mixing chamber. The vacuumizing mixing machine has the advantages that the mixing chamber can be automatically vacuumized in a working process, so that harmful gases in the mixing chamber are prevented from being exhausted to the outside and further causing pollution, chemical materials in the mixing chamber are prevented from being oxidized by outside air, and high-quality products can be produced; the vacuumizing mixing machine is of great significance in low-carbon development of the rubber and plastic industry and reduction of the energy consumption; the production efficiency and the quality of rubber products are guaranteed, and the vacuumizing mixing machine has an important strategic interest in building the modern high-quality, high-efficiency, energy-saving and emission-reducing type enterprises and establishing the environment-friendly society.

Description

technical field [0001] The invention relates to the technical field of chemical raw material internal mixing equipment, in particular to a vacuum internal mixer. Background technique [0002] The production of chemical and rubber and plastic products is generally through the blending of various chemical raw materials (such as: EVA, PE, PVC, TPV foaming agent, crosslinking agent, masterbatch, carbon fiber, carbon nanotubes, rubber and plastic blending, etc. Chemical raw materials) are colloidal and powdery synthetic materials formed after mixing. The internal mixer is a kind of mechanical equipment that can mix and stir a variety of chemical raw materials, and finally process them into a mixed jelly. When the existing internal mixer is mixing and mixing, there will be a phenomenon that the chemical formula raw materials are in the process of pressurized movement, and the air goes in and out repeatedly. At the same time, the air with high oxygen content around the banbur...

AI Technical Summary

Problems solved by technology

When the existing internal mixer is mixing and mixing, there will be a phenomenon that the chemical formula raw materials are in the process of pressurized movement, and the air goes in and out repeatedly. At the same time, the air with high oxygen content around the banbury room will be continuously and fully contacted with the materials in the banbury room, resulting in the following technical defects of the existing banbury mixer: 1. The workshop environment is polluted, During the mixing process of chemical raw materials, harmful gases may be produced, such as: polyoxymethylene, epoxy resin and other harmful gases; Second, chemical raw materials are constantly oxidized, resulting in the deterioration of chemical raw materials before they are fully mixed ; 3. The proportion of various chemical raw material formulas is out of balance, which seriously affects the quality of products
