Description

Mixing device for manufacturing recycled ascon by using waste ascon}

The present invention relates to a mixing apparatus for producing recycled ascon using waste ascon, and more preferably to mixing recycled ascon, a filling material (limestone, lime), an emulsifier, gravel and sand, etc. The apparatus is to separate the fine paste remaining on the surface of the waste ascon and mix well, and to control and discharge the mixing time by a timer, thereby obtaining high-quality recycled ascon.

In general, asphalt pavement is stacked in a plurality of layers on the road pavement or parking lot. Ascon is a term used to reduce asphalt concrete, and refers to a mixture of asphalt and sand, gravel, dust, and additives, which are heated, and are widely used in road paving and parking lots. In general, about 1,000 kg of asphalt concrete, it contains about 900 ~ 950 kg of aggregate (gravel, sand, dust, fila) and about 30 ~ 50 kg asphalt components. Ascon paved on the road is an important social overhead capital One must either be constantly on the road or be constantly repaired.

The road is rapidly deteriorated due to the rapid increase in weight and weight of the vehicle, and a large amount of waste ascon is generated as the road is continuously constructed and repaired for high speed and increased lanes.

That is, when it is collected due to construction work, natural disasters, road damage, etc., it is classified as industrial waste and treated or disposed of as waste.

Currently, some developed countries recycle 80-90% of the waste ascon, and Korea is strongly recommending recycling of the waste ascon. In addition, the waste ascon recycling policy is being systematically supplemented and strengthened, and progress has been made in terms of facilities for recycling waste ascon.

However, recycled ascon facilities that can recycle waste ascon still expose many problems.

Regenerated ascon facilities are implemented in various forms, including room temperature regenerated ascon equipment and heated regenerated ascon equipment. Currently, it is common in Korea to produce regenerated ascones by using a heated regenerated ascon equipment.

Heat regeneration ascon equipment is a facility to obtain regenerated ascon by heating and melting the separately collected waste ascon with a burner and a dryer and injecting the melted waste ascon into a mixer which is a new ascon mixing unit and mixing new aggregate and additive together. Are classified into a top type and a skip type.

However, in the reclaimed ascon facility of the prior art, the pulverized waste ascon stored in a cold bin, which is a reservoir, transfers and supplies the waste ascon to the upper regeneration dryer through a conveying means such as a conveyor and a hot elevator. Then, ascon is produced by heating and melting using a burner internal burner, transferring the mixture to a blender, and mixing the mixture.

Since the mixer apparatus used to produce the waste ascon as described above is composed mostly of a known device (not shown above) including a drive motor, a reduction mechanism, and a stirring blade, and a discharge port opened and closed by a hydraulic cylinder. For example, it is difficult to control the amount of the mixture, such as waste ascon, which is injected, and there is a problem in that it is impossible to accurately measure how much of the mixture should be discharged.

In addition, the waste ascon does not completely remove the paste attached to the waste ascon when broken in the impact crusher. Therefore, the waste ascon with paste is mixed into a conventional mixer as it is, so that the mixture flows between the waste ascon and the paste to weaken the strength of the recycled ascon, and thus there is a problem in that a high quality recycled ascon is not obtained.

The present invention was created in order to solve the above problems, in order to manufacture recycled ascon, stirring blades mounted on the stirring shaft rotating in the inner center of the mixing device for mixing by mixing waste ascone, filler and gravel and sand, etc. And, since the plurality of rotary blades mounted on the lower side of the main body of the mixing apparatus, the remaining fine paste is completely separated and mixed while rotating vertically and horizontally by the stirring blade and the rotating blade, without being separated from the surface of the waste ascon. The purpose of the present invention is to increase the strength of the waste ascon so as to obtain high quality recycled ascon.

In addition, the present invention is to automatically weigh the mixture such as the waste ascon into the mixing device is formed inclined cylindrical mixing container by the weighing machine attached to each storage tank automatically the amount of the mixture to be injected into the mixing device It is intended to block so that only the mixed mixture can be mixed perfectly.

In addition, by mixing the mixture such as waste ascon weighed by the weighing machine precisely for the time set in the timer, and discharged through the outlet formed in the side bottom of the mixing device, a high mixing ratio and high strength recycled ascon can be obtained For the purpose of

In addition, a plurality of stirring blades mounted on the stirring shaft are alternately repeatedly arranged in a cross shape at the top, and the lower part is formed in an arc shape so that the mixture at the bottom of the mixing device can be continuously discharged through the outlet without leaving any mixture. The purpose.
