Abstract

The utility model relates to a machine for road construction and rehabilitation, in particular to a blender for preparing asphalt mixture of the road paving materials, which solves the problem that the current blender can not directly process cold mineral materials. The utility model can be directly applied to cold mineral materials, not only for heating the cold mineral materials, but also uniformly mixing the cold mineral materials with the emitted liquid asphalt. The utility model is characterized in that a microwave heating device is at least arranged on the upper part of the shell body of the blender. The blender can be widely used in road construction and rehabilitation for preparing asphalt mixture.

Description

A kind of agitator

One, technical field:

The utility model relates to a kind of machinery of using with repairing road of building, particularly a kind of agitator for preparing the road paving materials asphalt.

Two, background technology:

The function of agitator is that the liquid asphalt with load weighted aggregate, stone flour and ejection by a certain percentage mixes into needed finished product asphalt equably.Its used aggregate must will be dried in the drying drum of fuel oil earlier, and is heated to certain temperature, and then flows to it.So not only make the equipment of preparation finished product material numerous and jumbled, cause dust pollution during cylinder work, and a large amount of heat that in the course of conveying of heat material, can scatter and disappear, energy dissipation caused.

Three, summary of the invention;

The purpose of this utility model is exactly will solve agitator can not provide a kind of cold mineral aggregate that is directly used in directly to the problem of cold mineral aggregate processing, can heat it, again the agitator that itself and the liquid asphalt that sprays evenly can be mixed.

The technical solution of the utility model is such, a kind of agitator, it has housing, liner plate is housed in housing, be contained on the shaft in the housing mixing arm is housed, paddle is arranged on the mixing arm, charging aperture is arranged at housing top, discharging opening is arranged at the bottom, it is characterized in that on the top of housing a microwave heating equipment being housed at least.

This microwave heating equipment has the hood-shaped cavity of a metal lower open, and the waveguide mouth is housed in cavity, and the magnetron that links to each other with transformer is housed on the waveguide mouth.

In this microwave heating equipment, that the shape of waveguide mouth can be is tubular, basin shape or taper, comprises taper shape and pyramid, also can be their combined shaped, and the waveguide mouth is made by metal material.

After cold mineral aggregate was poured into from the charging aperture on this agitator top, elder generation is air blown asphalt not, starts agitator, and the microwave heating equipment on top promptly begins the mineral aggregate that is rolling is carried out drying and heating.Heating is rapid because heating using microwave has, penetration power is strong, and its external heat scatters and disappears less again, so it has the much higher thermal efficiency than drying drum.After mineral aggregate reaches certain temperature, with regard to ejectable liquid pitch, mineral aggregate and pitch are mixed under the environment that continues heating, therefore the uniformity that stirs like this can be better, improve the quality of finished product material.In addition, dust from flying also owing to its rolls into one heating and stirring, thereby had been simplified the equipment of producing the finished product material to the pollution of environment when this agitator had not only been eliminated drying drum work, had significantly reduced equipment investment and occupation area of equipment.When building, can extensively adopt this agitator to prepare asphalt with repairing road

Four, description of drawings:

Accompanying drawing 1 is the front view of the utility model embodiment one;

Accompanying drawing 2 is A-A cutaway views of the utility model embodiment one;

Accompanying drawing 3 is front views of the utility model embodiment two;

Accompanying drawing 4 is that the B of the utility model embodiment two is to view.

Five, the specific embodiment:

Embodiment one:

Present embodiment is a horizontal-type biaxial leaf slurry agitator.As can be seen from Figure 1, it has housing 1, and liner plate 7 is housed in housing 1, be contained on the shaft 2 in the housing 1, mixing arm 3 is housed, paddle 4 is arranged on the mixing arm 3, charging aperture 6 is arranged at housing 1 top, and discharging opening 5 is arranged at the bottom, near charging aperture 6 microwave heating equipment is housed on the top of housing 1.Find out from Fig. 1 and Fig. 2, the hood-shaped cavity 8 that microwave heating equipment has a steel plate to make, it uses bolted on end face on the housing 1.The bottom of cavity 8 is opened wide, and communicates with the inner chamber of housing 1, and end face on cavity 8 inside is equipped with 3 rows, 3 row totally nine waveguide mouths 12 with screw.The shape on the top of waveguide mouth 12 is that cross section is the straight tube of rectangle, and lower shape is a pyramid, and waveguide mouth 12 is made by copper coin, and the bottom of adjacent waveguide mouth 12 joins.A magnetron 9 all is housed on each waveguide mouth 12, and each magnetron 9 all is connected with the transformer 10 of the usefulness of boosting, and transformer 10 joins by lead 11 and external power source.

Embodiment 2:

Present embodiment also is a horizontal-type biaxial leaf slurry agitator.As can be seen from Figure 3, what it was different with embodiment one is, it housing 1 on first and two microwave heating equipments of second are housed on the end face, charging aperture 6 is positioned at the centre of these two microwave heating equipments.As can be seen from Figure 4, first and second respectively have 3 waveguide mouths.Because other structures of present embodiment are identical with embodiment one, so no longer repeat at this.

Claims

1, a kind of agitator, it has housing, and liner plate is housed in housing, be contained on the shaft in the housing mixing arm is housed, paddle is arranged on the mixing arm, charging aperture is arranged at housing top, discharging opening is arranged at the bottom, it is characterized in that on the top of housing a microwave heating equipment being housed at least.

2, a kind of agitator according to claim 1 is characterized in that each microwave heating equipment all has the hood-shaped cavity of a metal lower open, and the waveguide mouth is housed in cavity, and the magnetron that links to each other with transformer is housed on the waveguide mouth.。
