Abstract

The utility model discloses a modified asphalt processing device which comprises a reaction kettle, a raw asphalt feed port, a modifying agent feed port, and a discharge port, wherein, a heating tube is wound around the outer wall of the reaction kettle, and a high velocity shearing emulsifier is installed in the reaction kettle and is connected with a motor. The utility model utilizes the high velocity shearing emulsifier to carry out tearing, shearing, crushing, and stirring operation to the mixture of raw asphalt and modifying agents to achieve the modifying effect and has the advantages of simple and compact structure, favorable sealing performance, high efficiency, low cost and favorable effect.

Description

A kind of modifying asphalt processing units

The utility model relates to a kind of processing modified bituminous equipment that is used for.

Common modified asphalt processing technic mainly contains parent method, direct throw-in play, mechanical mixing method etc., and wherein the parent method need consume a large amount of valency height, virose solvent, modifying asphalt cost height, and be unfavorable for environmental protection; Directly throw-in play needs elder generation with the material modified latex of making, because the latex water content is big, has increased complicated dehydration, and modified effect is also higher; Mechanical mixing method production efficiency is low, material modifiedly is difficult to be crushed to enough fineness and being uniformly dispersed.And because the aforesaid method complex process causes the also corresponding complexity of processing units.Up-to-date colloid milling employing colloidal mill is pulverized properties-correcting agent and is made it and mixes with protobitumen, and processing effect is better, but the colloidal mill price is higher, wearing and tearing easily, and sealing problem also is difficult to solve simultaneously.

The purpose of this utility model provides a kind of simple in structure, compact, good airproof performance, efficient height, can simplified processing process guarantees the modifying asphalt processing units of modified effect simultaneously.

Protobitumen opening for feed, properties-correcting agent opening for feed and discharge port that the utility model comprises reactor, links to each other with reactor, the reactor outer wall is around heating tube, and the high speed shear emulsor is installed in reactor inside, and links to each other with motor.

High speed shear emulsor in the reactor is driven by high-speed electric expreess locomotive, properties-correcting agent and bituminous compound are sucked from the reactor bottom, make it from the fine gap of the rotor of high speed shear emulsor and stator, to pass through, accept intensive mechanical shearing and fluid power and shear, at this, properties-correcting agent is torn, shears, pulverizes and disperses, then, the hole of compound on stator made radial spray and gone out, and forms the effect of rolling up and down in reactor, guarantees the thorough mixing of protobitumen and properties-correcting agent.Simultaneously, pass to high-temperature oil liquid in the heating tube, make reactor inside in the course of processing, remain the condition of high temperature, thereby make compound that good flowability be arranged, help carrying out smoothly of work program.The utility model is simple in structure, compact, just can finish the course of processing of modifying asphalt in single device substantially, and good airproof performance, cost are low, effective.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, protobitumen opening for feed 2, properties-correcting agent import 3 and discharge port 4 that the utility model comprises reactor 1, links to each other with reactor, reactor outer wall are around heating tube 5, and high speed shear emulsor 6 is installed in reactor 1 inside, and links to each other with motor 7.Wherein the high speed shear emulsor is a prior art.Adjustable for height dispersion impeller 9 also is housed in the rotating shaft 8 of motor 7, this impeller produces in the material in reactor during with the machine shaft high speed rotating to the eddy current that presses down, be engaged in the violent turbulent flow of formation in the reactor with the high speed shear emulsor, make protobitumen fully contact and mix with properties-correcting agent.A wiper agitator 10 that is the anchor shape also is equipped with in reactor 1 bottom, and the wiper agitator links to each other near the reactor inwall and with motor.Its effect is that wiper is deposited at the bottom of the still or sticks to the material of still wall, and it is joined in the circulation of high speed shear emulsive again, and it is more even to help properties-correcting agent to disperse, and prevents the dead angle.
