Method and equipment for mixing modified asphalt through pump circulation

Abstract

This invention discloses an improved asphalt circulation pump mixing equipment, which comprises a tank, a stir axis and stir blades connected with the stir axis. The stir axis and the stir blades are in the tank. A high-pressure pump through connected with asphalt inflow pipe and asphalt outflow pipe is set beside the tank. The asphalt inflow pipe is through connected with the hollow chamber of the tank. The asphalt outflow pipe is connected with the circular high-pressure pipe in the hollow chamber of the tank. Multiple high-pressure spray nozzles that can form rotary flows are through connected with the high-pressure pipe with a certain interval. The said circulation pump apparatus is set at the low part of the tank. By combination of stirrer and circulation pump apparatus for stirring, the circulation pump apparatus can continuous extract asphalt mixture from the asphalt container. The asphalt mixture, after passing through the high-pressure pump, can be sprayed at a high speed approximately along the tangent direction by the spray nozzles, thus forming rotary flows. The equipment in this invention can improve the production capacity, save energy, prolong the equipment service life, reduce the cost, and guarantee the product quality.

Description

technical field [0001] The invention relates to a method and equipment for circulating and mixing modified asphalt pumps. Background technique [0002] The storage of modified asphalt and the mixing of various additives in the prior art use mechanical stirring, and the rotation of the stirring blade connected to the stirring shaft in the container makes the asphalt and additives continuously tumbling to achieve the mixing of various components. uniform effect. The utility model patent with the Chinese patent application authorization announcement number CN2161619Y discloses a stirring modified asphalt processing device, which is composed of a circular container, a power device, a speed change device, a stirring shaft, an impeller, and an asphalt pump, wherein the power device and The speed change device is installed outside the container, and one end of the shaft is equipped with an impeller placed in the container, and the container is provided with an inlet and equipped w...
