Description

technical field [0001] The invention relates to an ion-type mixing internal mixer, which belongs to the technical field of raw rubber internal mixing. Background technique [0002] At present, there are two ways of refining raw rubber, one is the open refining method, and the other is the internal mixing method. From the overall effect, the internal mixing method is better than the open refining method. There are many types of internal mixing on the market. Most of the machines are simple in structure, single in function and consistent in principle. They are roughly divided into the following structures: hydraulic device, extrusion rotating device, cooling device, and control device. The principle of internal mixing is to put softened powder into the internal mixer, and then Put the raw rubber in, use the hydraulic cylinder to squeeze the raw rubber into the internal mixer, start the extrusion rotating device, the extrusion wheel starts to rotate, squeeze, tear and recombine...

[0002] At present, there are two ways of refining raw rubber, one is the open refining method, and the other is the internal mixing method. From the overall effect, the internal mixing method is better than the open refining method. There are many types of internal mixing on the market. Most of the machines are simple in structure, single in function and consistent in principle. They are roughly divided into the following structures: hydraulic device, extrusion rotating device, cooling device, and control device. The principle of internal mixing is to put softened powder into the internal mixer, and then Put the raw rubber in, use the hydraulic cylinder to squeeze the raw rubber into the internal mixer, start the extrusion rotating device, the extrusion wheel starts to rotate, squeeze, tear and recombine the raw rubber according to the special-shaped structure on it, and extrude The continuous rotation of the wheel can make the softened powder and the recombined raw rubber evenly mixed. However, a large amount of heat will be generated in the process of tearing and recombining the raw rubber, which will cause the temperature in the mixing wall to rise sharply. Temperature will affect the fluidity of rubber, which requires a large amount of water to circulate and cool, which will cause waste of water resources. At the same time, the uniform mixing of softened powder requires long-term rotation of the extrusion wheel, which reduces production efficiency. In addition, the fugitive dust generated during the banburying of the softened powder is easily extruded by the air of the equipment to cause environmental pollution, which is not conducive to the health of the operators. For example, a vacuum mixer provided by the Chinese invention patent application number: 201310525322. The top of the mixing room is equipped with a vacuum device for vacuuming the mixing room. During the working process, the mixing room is automatically vacuumed to prevent the harmful gas in the mixing room from being discharged to the outside and causing pollution, and to prevent the chemical industry in the mixing room. The raw material is oxidized by the outside air to ensure that high-quality products can be produced, but this vacuum effect will cause the added powder to be drawn out, which will affect the performance of the rubber after banburying. Therefore, the invention provides an ionic compound Internal mixer
