Nanofiller pre-dispersing device for wet mixing

Abstract

The invention discloses a nanofiller pre-dispersing device for wet mixing. The nanofiller pre-dispersing device comprises a rack, a graduated scale fixed on the right side of the rack; an air blower fixed above the graduated scale; a control valve connected with the air outlet buffer pipe section of the air blower; a straight pipe section connected with the control valve; a gas flow meter arranged on the straight pipe section; an inhaul cable used for reinforcing the straight pipe section and fixed on the cantilever beam; a right-angled elbow connected with the left end surface of the straight pipe section; a hopper fixed on the square elbow; a buffer straight pipe section connected with the lower end surface of the square elbow; a pressure gauge fixed on the left side of the buffer straight pipe section; a diverging pipe being in butt joint with the buffer straight pipe section; a cylindrical enclosure positioned right below the diverging pipe; and a supporting mechanism of the cylindrical fence. The nanofiller pre-dispersing device for wet-process mixing provided by the invention aims to realize filler pre-dispersion before latex-filler stirring and mixing in wet-process mixing, and can improve the uniform dispersion effect of the nano-filler, reduce the stirring and mixing time and improve the production efficiency in comparison with direct feeding of the filler, thereby realizing consumption reduction, emission reduction, low carbon and environmental protection.

Description

technical field [0001] The invention relates to the technical field of rubber wet mixing, in particular to a nano filler predispersing device for wet mixing. Background technique [0002] The mixing process is essential in the production process of rubber products. Wet mixing technology is to complete the mixing and dispersion of filler and latex in the container. Compared with the dry mixing method, the wet mixing technology can reduce mixing energy consumption, realize energy saving and carbon reduction, reduce dust pollution, and provide a clean working environment. [0003] In the existing wet mixing technology, in order to improve the dispersion uniformity of nano fillers, the latex can be ultrasonically treated and then mixed with fillers. After drying, the masterbatch can be obtained; the latex and the filler solution can also be atomized separately, and then mixed, or the latex-filler mixture can be atomized and mixed to obtain a coagulated rubber mixture, and then...

Problems solved by technology

However, it is difficult to expand the production scale by using ultrasonic treatment, which cannot meet the needs of existing production; and the latex and filler solution are atomized separately or the latex-filler mixture is atomized and then mixed, and it needs to be well sealed and contains high-pressure static electricity.
