Abstract

A helical and paddle type composite agitator with a special-shaped dispersing disc and a comb spoiler, characterized in that it consists of a stirring tank assembly, a helical agitator assembly, a paddle agitator assembly, a double-sided helical tooth dispersing Composed of disc assembly, turbine blade type dispersing disc assembly and motor; the inner wall of the tank is welded with a comb spoiler, when the agitator is working, the streamline coverage inside the agitator is better, and the streamline has a relatively ideal vortex area , the design of the comb teeth can reduce the fouling of the material at the spoiler; the diameter of the special-shaped dispersing disc is larger, which can increase the coverage of the streamline at the bottom and the velocity range of the flow field during the stirring process, reduce the dead zone of stirring, and improve Stirring efficiency; there are helical blades with variable diameter and variable pitch on the screw shaft, the lower pitch of the blade is smaller, the diameter is larger, the helix angle is small, the vertical lifting speed of the ingredients is smaller, the stirring effect is better, and the upper pitch of the blade is smaller. The larger diameter is smaller, and the vertical speed of ingredients is greatly increased, which is more conducive to the spiral upward movement of ingredients.

Description

technical field

[0001] The invention belongs to the field of fluid machinery, and in particular relates to a screw type and paddle type composite agitator with a special-shaped dispersing disc and a comb spoiler. Background technique

[0002] At present, asphalt waterproof material is a kind of building material widely used in industrial and civil building waterproofing, moistureproofing, municipal engineering waterproofing, and water conservancy facility waterproofing. It has good adhesion, plasticity, water resistance and corrosion resistance. Among them, Modified asphalt waterproofing membrane is the most widely used. Modified asphalt is an asphalt mixture made by adding high molecular polymers as modifiers to asphalt and uniformly mixing with asphalt to improve the properties of asphalt. Common modifiers include SBS and SBR; due to polymer polymerization The modified asphalt mixture is a high-viscosity, heterogeneous fluid, and there is partial adsorption between the po...
