Description
Technical Field
The utility model relates to the technical field of asphalt production equipment, in particular to a multi-effect compound asphalt colloid mill.
Background
The gap between the stator and the rotor of the conventional common colloid mill can be adjusted, and the gap between the stator and the rotor is constant from the feed inlet to the discharge outlet after adjustment. And the particle size of the material is largest at the feed inlet and smallest at the discharge outlet. The impact force and shearing force of the stator and the rotor near the feed port are greatly higher than those of the stator and the rotor at the discharge port. The abrasion of the stator and the rotor near the feed inlet is large, and the service life is short. The stator and the rotor close to the discharge port end are small in impact force and shearing force and relatively long in service life. It is obvious that the life of stator and rotor is not in accordance with the life principle of parts used in mechanical design. Moreover, the existing asphalt colloid mill is often only suitable for the production of a certain type of asphalt, and is difficult to be simultaneously suitable for the production of different types of asphalt such as rubber asphalt, modified asphalt, composite rubber asphalt and the like.
For example, existing modified asphalt colloid mills are only suitable for SBS (or SBR) modified asphalt production, and cannot be simply imitated for rubber asphalt production, particularly high-blending-amount rubber asphalt production. The additives such as scrap iron, calcium powder, carbon black and the like in the rubber powder can cause accelerated abrasion of a grinding seal, a grinding main shaft and a grinding disc, leakage and grinding disc scrapping. The millstone clearance of the traditional modified asphalt colloid mill is smaller, and if rubber asphalt is to be produced, the colloid mill is blocked and cannot be produced due to large mixing amount of rubber powder; if rubber powder is not added during rubber asphalt production, but rubber particles are added, the existing colloid mill is more difficult to finish production, and particles are easy to block at an inlet after being sent into the colloid mill. The imported colloid mill has high price and high maintenance cost, and is also not suitable for producing rubber asphalt.
In addition, if the existing emulsified asphalt fails in the production process, demulsification is caused, the obtained demulsified emulsified asphalt can be only discarded, and is difficult to recycle, and the existing asphalt colloid mill cannot process the emulsified asphalt, so that resource waste and cost are increased.

the surface of the stator, which is close to the rotor, is an arc convex surface, the surface of the rotor, which is close to the stator, is an arc concave surface, and cutting edges are uniformly distributed on the arc convex surface of the stator and the arc concave surface of the rotor;
the gap between the stator and the rotor forms a processing area, one end of the processing area faces the feed inlet, and the other end of the processing area faces the discharge outlet;
and the radian of the arc convex surface of the stator is different from that of the arc concave surface of the rotor, so that the opening gap of the processing area towards one end of the feeding port is larger, the opening gap of the processing area towards one end of the discharging port is smaller, and the whole processing area is conical.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model easy to understand, the following further describes how the present utility model is implemented with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the utility model provides a multi-effect compound asphalt colloid mill, which comprises a shell 1, a stator 3 and a rotor 4 arranged in the shell 1; the stator 3 is fixedly arranged in the shell 1, and the rotor 4 can rotate relative to the stator 3; the shell 1 is also provided with a feed inlet and a discharge outlet; the surface of the stator 3, which is close to the rotor 4, is an arc convex surface, the surface of the rotor 4, which is close to the stator 3, is an arc concave surface, and cutting edges are uniformly distributed on the arc convex surface of the stator 3 and the arc concave surface of the rotor 4; the gap between the stator 3 and the rotor 4 forms a processing area 2, one end of the processing area 2 faces the feed inlet, and the other end faces the discharge outlet; moreover, the radian of the arc-shaped convex surface of the stator 3 is different from that of the arc-shaped concave surface of the rotor 4, so that the opening gap of the machining area 2 towards one end of the feed inlet is larger, the opening gap of the machining area 2 towards one end of the discharge outlet is smaller, and the whole machining area 2 is conical.
Further, the rotor 4 can rotate under the control of an external motor, and the output end of the motor extends into the housing 1 through the rotating shaft 5 and is fixedly connected with one end, far away from the stator 3, of the rotor 4.
Preferably, the blades on the arcuate concave surface of the rotor 4 are conical helical blades.
It can be understood that the working principle of the colloid mill is as follows: the rotor 4 and the matched stator 3 rotate at a relatively high speed, the processed material is pressurized by the weight of the processed material or external pressure to generate downward spiral impact force, and the processed material is subjected to strong physical actions such as shearing force, friction force, high-frequency vibration and the like when passing through a gap between the stator and the rotor 4, so that the processed material is effectively emulsified, dispersed and crushed, and the effect of finely crushing the processed material is achieved.
As described in the background art, the existing colloid mill has various problems, and is difficult to adapt to the production of different kinds of asphalt. The multi-effect compound asphalt colloid mill provided by the utility model is suitable for producing different asphalt types such as rubber asphalt, modified asphalt, compound rubber asphalt and the like. Taking the production of rubber asphalt as an example, adjacent convex and concave surfaces of a stator 3 and a rotor 4 adopt special structures so as to form a conical processing area 2. When the rotor 4 rotates at a high speed along with the rotating shaft 5, under the action of strong shearing force, huge angular impulse is generated at the edges of the convex and concave surfaces of the stator 3 and the rotor 4 of the colloid mill, and meanwhile, intense relative friction, rotation, impact and collision are generated, and the conical spiral blades uniformly distributed on the rotor 4 are beneficial to the generation of tearing and cutting actions, so that the effects of dispersion, homogenization and fine grinding are achieved; additional axial force can be generated to assist in pushing crushed rubber asphalt micro molecules to a discharge port; in the high-speed rotation motion of the rotor 4, the momentum and mass exchange between the speed fluctuation and the adjacent convex and concave surfaces of the stator 3 occurs, and turbulence is generated, so that the mixing, stirring and suspending effects are realized. The high-viscosity rubber asphalt causes a suction effect to press objects into the dispersed and ground conical processing area 2 under the self gravity and the pushing action of the conical spiral blade on the rotor 4, thereby being more beneficial to suction, conveying and grinding of the rubber asphalt.
In addition, in the utility model, the inlet end opening is large, which is beneficial to feeding the block-shaped rubber asphalt; the small opening of the outlet end is beneficial to controlling the particle size of the rubber asphalt flowing to the discharge port, and meets the requirements. The opening of the inlet end is large, which is beneficial to reducing the friction force between the rubber asphalt block and the convex and concave surfaces of the stator 3 and the rotor 4; the gap at the outlet end of the tapered processing region 2 is small, but the particle size of the asphalt molecules reaching the region is very small and uniform in all directions, so that the asphalt molecules can smoothly pass through the gap between the convex and concave surfaces. Therefore, the stator 3 and the rotor 4 have small fluctuation before and after stress in the whole area, which is more beneficial to the improvement of the service life of the stator 3 and the rotor 4.
In addition, for the demulsified asphalt, the multi-effect compound asphalt colloid mill provided by the utility model can grind and thin the bulk or strip demulsified asphalt, so that the activation and recycling of the waste asphalt are realized.
In summary, the multi-effect compound asphalt colloid mill provided by the utility model has the advantages that the conical processing area 2 is designed, the opening is gradual from large to small, the large-particle-size materials can enter conveniently, the problems of the conventional colloid mill can be effectively solved, the suction, the conveying and the grinding of asphalt are more facilitated, and the service lives of a rotor and a stator can be prolonged; is suitable for producing different asphalt types such as rubber asphalt, modified asphalt, composite rubber asphalt and the like, and can realize reutilization after demulsification emulsified asphalt is treated.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
