Inert gas protection apparatus and rubber blending extrusion equipment

Abstract

The invention discloses an inert gas protection apparatus for rubber blending extrusion equipment. The inert gas protection apparatus comprises a sealing barrel, wherein both ends of the sealing barrel are respectively provided with a material inlet and a material outlet, and the material outlet position is provided with a gas introduction port for introducing an inert gas. According to the present invention, the inert gas protection apparatus is provided with the sealing barrel so as to reduce the possibility of air intrusion and prevent high-temperature rubber particles from being oxidized by air; the inert gas is introduced by arranging the gas introduction port, such that the inert gas atmosphere can be conveniently generated in the sealing barrel, and the rubber particles in the hightemperature state can be protected and can be prevented from being oxidized before cooling; and by arranging the gas introduction port for introducing the inert gas at the material outlet, the rubbermaterial discharge direction is opposite to the inert gas introduction direction, such that the rubber material can be completely enclosed by the inert gas to form the anti-oxidation atmosphere aroundthe rubber material so as to well protect the rubber material. The invention further discloses rubber blending extrusion equipment.

Description

technical field [0001] The invention relates to the technical field of rubber production and processing, more specifically, to an inert gas protection device, and to rubber blending and extrusion equipment. Background technique [0002] The traditional natural rubber processing technology is to store fresh latex statically, gel in a microbial or acid environment, wash, squeeze, and dry the gel to make standard rubber and provide it to downstream customers. When processing rubber products such as tires, it is necessary to add a certain amount of inorganic fillers. The current practice is to put the standard rubber and inorganic fillers into the internal mixer for dry mixing, which consumes a lot of energy, and the kneading and mixing process is harmful to the rubber. The molecular weight and physical properties are destroyed. In order to solve this problem, natural rubber wet mixing technology has been developed and applied in recent years, that is, natural rubber latex and ...
