Description

Technical Field

[0001] This utility model relates to the field of mixing reactor technology, and more specifically, to a mixing reactor for processing styrene-butadiene rubber latex. Background Technology

[0002] Emulsion-polymerized styrene-butadiene rubber (SBR) is produced by emulsion polymerization of butadiene and styrene as the main monomers, along with other auxiliary chemical raw materials, under certain process conditions. First, SBR latex is generated through emulsion polymerization. After removing unconverted monomers from the latex, the product rubber is produced through processes such as coagulation and drying. During the processing of SBR latex, mixing equipment is needed to stir and mix the raw materials. For example, patent CN209188723U discloses a solid-liquid-gas mixing reactor, including an inner cylinder and a jacketed cylinder. The jacketed cylinder has lugs on its exterior, and the inner cylinder contains a gas distributor and a bubbling self-circulating agitator. The gas distributor is a horizontal annular gas distribution pipe with symmetrical gas inlets on both sides. The two gas inlets are connected to the flue gas inlet at the top of the inner cylinder via vertically arranged gas pipes. The gas distribution pipe also has two exhaust ports. The bubbling self-circulating agitator includes a stirring rod and two layers of stirring paddles, which are respectively positioned in the middle and bottom of the inner cylinder via the stirring rod.

[0003] When the above-mentioned device is in use, it can fully mix the solid, liquid and gas three-phase reactants to form a uniformly dispersed system, which is beneficial to accelerate the reaction rate. However, the liquid level of the styrene-butadiene rubber latex inside the stirrer is different, and the height of the stirring paddle cannot be adjusted according to the liquid level. When stirring styrene-butadiene rubber latex raw materials at different heights, the stirring efficiency is easily affected. Utility Model Content
