Uniform heating and mixing device for magnetic centrifugal bubble-removal road construction material

Abstract

The invention discloses a uniform heating and mixing device for a magnetic centrifugal bubble-removal road construction material. The uniform heating and mixing device structurally comprises a rotarymotor, a heating circulating pump, a feeding pipe, a uniform circulating heat-conducting and bubble-removal device, a discharging pipe and a support base, wherein the heating circulating pump is mounted on the left side of the rotary motor. According to the uniform heating and mixing device, bubbles of a mixed solution bubbling outside a first heat-conducting pipe and a second heat-conducting aretimely removed through a flow-guiding and bubble-removal structure, the mixed solution and the bubbles are separated through different centrifugal forces of a magnetic centrifuging mechanism in a flow-guiding plate to the mixed solution and the bubbles, the mixed solution slowly flows downwards along an inner wall plate and is circulated through a draining hole, the separated bubbles are discharged into atmosphere through the filtration and purification of a filter, so that the situation that the quality of an asphalt mixed solution is influenced because the bubbles are dispersed in all directions and are difficult to be cleared is prevented.

Description

technical field [0001] The invention relates to the field of uniform heating and mixing devices for road building materials, more precisely, it relates to a uniform heating and mixing device for road building materials by magnetic centrifugal degassing. Background technique [0002] At present, asphalt materials are used more and more widely in road construction. Asphalt has functions such as waterproof and anti-corrosion. However, the temperature control of asphalt during processing should be more precise. At present, it is mainly heated by steam or electric heating. The existing traditional Technical considerations are not comprehensive and have the following disadvantages: [0003] The heating temperature control of the asphalt is not precise enough, and the heat conduction heating is not uniform enough, so that the local heating temperature of the asphalt is too high. Due to the temperature difference, air bubbles are easily generated on the contact surface between the a...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a magnetic centrifuge air removal and uniform heating and mixing device for road building materials, so as to solve the problems in the prior art that the heating temperature control of the asphalt is not accurate enough, and the heat conduction heating is not uniform enough, so that the asphalt is locally heated The temperature is too high. Due to the temperature difference, air bubbles are easy to form on the contact surface between the asphalt mixture and the heater, and the asphalt mixture is relatively viscous, so the generated air bubbles are not easy to float up and get rid of, and the air bubbles in the asphalt mixture destroy its tight adhesion. The structure reduces the waterproof and anti-corrosion performance of asphalt and reduces its service life.
