Problems solved by technology

Sometimes larger and more SBS particles are added to the asphalt tank. Due to the high viscosity of the liquid, ordinary mixing tanks cannot completely break the rubber particles, so that they cannot be completely dissolved in the liquid, and the mixing is very uneven. So the mixing effect is not ideal

Abstract

The invention belongs to the technical field of machines, and discloses a stirring tank used for blending high-molecular rubber and asphalt. The stirring tank comprises: a rubber feeding opening and an asphalt feeding opening which are arranged at the top end of the stirring tank; a discharging opening arranged at the bottom end of the stirring tank; and a stirring shaft arranged in the stirring tank, wherein the stirring shaft is connected with a stirring motor through a connecting flange arranged at the top end of the stirring shaft, and a heat conduction channel is formed by a stirring tank outer wall and a channel shell part fixed on the stirring tank outer wall; and the periphery of the stirring shaft is sheathed with middle blade structures and a bottom blade structure from top to bottom, the bottom blade structure is provided with bottom blades, every middle blade structure comprises a blade sleeve and stirring blades, the middle blade structures sleeve the stirring shaft through the blade sleeves, and every stirring blade is provided with a sawtooth. The stirring tank has the advantages of guaranteeing of the quality of rubber modified asphalt, direct heating of the stirring tank outer wall, large heating area, uniform heating, facilitation of fusion of rubber and asphalt, and good stirring effect.

Description

technical field [0001] The invention relates to a mixing tank, in particular to a mixing tank blended with polymer rubber and asphalt, and belongs to the field of mechanical technology. Background technique [0002] In the prior art, the heating treatment of the stirring tank is realized by providing an external heating jacket and a built-in heating coil on the horizontal stirring tank. However, the heating coil is arranged inside the mixing tank. On the one hand, there are many dead angles on the contact surface between the coil and the inner wall of the mixing tank. When the rubber powder and asphalt are stirred in the horizontal mixing tank, they cannot be uniformly dispersed. Segregation and a small part of the rubber powder and asphalt mixture will remain in the dead corner during the mixing process, and will not flow out of the mixing tank with the rubber asphalt mixture; therefore, sticking to the dead corner around the heating coil inside the horizontal mixing tank ...
