Description

Technical Field

[0001] The utility model relates to the technical field of acrylic rubber processing, in particular to a demulsification device dedicated to acrylic rubber. Background Art

[0002] In the prior art, the addition of demulsifiers in rubber production adopts traditional equipment and methods, that is, pumping from the upper part of the coagulation kettle. This equipment and method are simple and easy to operate, but the demulsifier first contacts the surface of the rubber liquid, and it is difficult to quickly disperse into the interior, so that the surface rubber liquid forms larger particles. As the solubility of the rubber liquid and the demulsifier decreases with the demulsification process, the demulsified particles are too small, which easily leads to the particle size of the acrylic rubber particles not meeting the standard. At the same time, the extremely small particles of acrylic rubber are lost with the wastewater in the subsequent rubber washing process, generating solid waste at the back end, causing material waste and environmental pollution.

[0003] Chinese patent publication number CN216910286U discloses a demulsifier dedicated to acrylic rubber, which disperses the demulsifier through multiple through holes at the bottom of the annular feed pipe, which is conducive to the rapid and uniform dispersion of the demulsifier, making the particle size of the acrylic rubber particles uniform, and at the same time does not produce extremely small particles of acrylic rubber, and does not cause material waste and environmental pollution in the subsequent rubber washing process.

[0004] The demulsifier in the above application mainly performs particle coagulation operation by evenly conveying the demulsifier to the interior of the coagulation kettle through the feed port and the annular feed pipe. However, the demulsifier in the above application does not have a pressurized structure, and the liquid water level inside the coagulation kettle is higher than the position of the annular feed pipe. Therefore, the demulsifier cannot be easily fed into the interior of the coagulation kettle, so there are certain limitations. Utility Model Content
