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 a modified asphalt pump. Background technique [0002] In the prior art, the storage of modified asphalt and the mixing of various additives adopt mechanical stirring, and use the rotation of the stirring blade connected with the stirring shaft in the container, so that the asphalt and additives are constantly tossed to achieve the mixing of multiple components. Uniform effect. The Chinese Patent Application Authorization Announcement No. CN2161619Y is a utility model patent, which discloses a mixing type modified asphalt processing device, which is composed of a circular container, a power device, a transmission device, a mixing shaft, an impeller, and an asphalt pump. The speed change device is installed outside the container, one end of the shaft is equipped with an impeller and placed in the container, and the container is provided with an inlet and an asphalt pump. With this str...
