Horizontal continuous polymerization reaction kettle for producing rubber powder modified bitumen

Abstract

The invention relates to a horizontal continuous polymerization reaction kettle for producing rubber powder modified bitumen, which is characterized by mainly comprising a reaction kettle main body, an additive bin, a rubber powder storage bin, a stirring shaft and a speed reducer. A rubber powder charge distributor and the additive bin are fixed on the upper cover of the reaction kettle main body respectively, wherein the rubber powder charge distributor is communicated with the inner cavity of the reaction kettle main body; a matrix bitumen inlet is formed on the front surface of the reaction kettle main body, and a finished product outlet is formed at the bottom of the reaction kettle main body; a front bearing box and a rear bearing box are fixed on the two side plates of the reactionkettle main body; the stirring shaft is supported by the front and rear bearing boxes; and the front bearing box is connected with the speed reducer through a coupling. The invention has the beneficial effects that: multiple independent bins separated by weir plates are arranged in the dual-kettle reaction kettle; the stirring blades completely cover the whole kettle, thereby eliminating the stirring dead angle; and various processing materials are sufficiently stirred and quickly blended in the reaction kettle. Due to closed production design, the reaction kettle can make full use of the heat energy in the production process, thereby reducing the energy consumption and lowering the production cost.

Description

Technical field [0001] The invention belongs to equipment for producing rubber powder modified asphalt, and particularly relates to a horizontal continuous polymerization reactor for producing rubber powder modified asphalt. Background technique [0002] Waste tires account for more than 60% of waste rubber products, so the comprehensive utilization of waste rubber mainly refers to the treatment and utilization of waste tires. Waste tires have strong heat resistance, mechanical resistance, and are difficult to degrade. They are stacked in the open for a long time, not only occupying land, but also prone to breeding mosquitoes, infectious diseases, and easy to cause fires. Reasonable disposal of waste tires has long been a problem for environmental protection. Waste rubber and waste plastic are called two major pollutants in modern society, and waste rubber is called "black pollution." With the advancement of science and technology, countries all over the world have actively dev...
