Vertical stirring tank for production of modified asphalt waterproof coiled material

Abstract

The invention discloses a vertical stirring tank for production of a modified asphalt waterproof coiled material. The vertical stirring tank comprises a tank body, the tank body is internally providedwith a stirring chamber, a feed pipe runs through the top side wall of the tank body, a discharge pipe runs through the lower side wall of the tan body, and an air vent runs through the top side wallof the tank body. Through the following two different stirring modes, i.e. double-helix belt impellers and stirring blades, the stirring can be fuller, the double-helix belt impellers can effectivelyscatter the produced agglomerates, promote the flow mixing of materials, roll and stir materials, and achieve a good stirring effect, not only can scrape the materials off the bottom of the stirringchamber, but also can scrape the materials off the inner side wall of the stirring chamber, thus effectively avoiding the high temperature ignition phenomenon caused by accumulation of a large numberof solid or powder modifiers on the stirring chamber inner wall around an asphalt liquid level.

Description

technical field [0001] The invention relates to the technical field of production equipment for waterproof coiled materials, in particular to a vertical mixing tank for production of modified asphalt waterproof coiled materials. Background technique [0002] Modified bitumen waterproofing membrane is made of synthetic high molecular polymer modified bitumen as the coating layer, fiber fabric or fiber felt as the carcass, and powdery, granular, sheet or film materials as the covering material to make a rollable sheet. The material, because of its excellent high and low temperature resistance, adopts the hot-melt method for construction, the method is simple and reliable, it can be constructed all year round, and is less affected by the construction area and ambient temperature, so it has been actively promoted and applied in China, and is widely used For building walls, roofs, tunnels, roads, landfills, etc., with the increase in demand, the single-line production capacity of...

AI Technical Summary

Problems solved by technology

[0003] The existing vertical mixing tanks for the production of modified asphalt waterproofing coils generally use only one mixing method for mixing. If the mixing is insufficient, it is easy to cause agglomeration due to the gravity of the material itself and the adhesion between the materials. The mixing effect Poor, and a large amount of solid or powder modifiers are accumulated on the inner wall of the mixing chamber around the asphalt liquid surface, which is prone to high-temperature ignition. Therefore, we propose a vertical mixing tank for the production of modified asphalt waterproof membranes. solve the above problems
