Description

Technical Field

[0001] The utility model relates to the technical field of recycling and reuse of materials in the field of road construction engineering, in particular to a vertical recycled material stirring and heating device. Background Art

[0002] The current production process is to collect the damaged road surface by milling and transport it back to the mixing plant for reuse (commonly known as recycled asphalt). The asphalt and stone in the recycled asphalt material should be used. The production process is to screen the milled material and heat the drying cylinder. The burner heats the recycled material in the rotating drying cylinder. The recycled material is heated in an environment similar to open flame, which makes the fine material with high asphalt content easy to burn, greatly reducing the efficiency of effective asphalt reuse. Moreover, the heated recycled asphalt fine material is very easy to stick to the wall of the heated drying cylinder. With the extension of production time, the thickness of the fine material stuck to the drying cylinder increases rapidly, the heat exchange material curtain deteriorates, the driving load increases with the increase in thickness, the heat exchange efficiency decreases, and the heat loss increases. Therefore: there are two fatal problems. One is that the recycled fine material with high asphalt content is easy to be coked during the original heating method. The other is that the heated fine recycled material is easy to stick to the drying cylinder, which brings a bad user experience. Utility Model Content

[0026] The drying cylinder 1 is provided with a feed inlet at the top and a discharge outlet at the bottom;

[0027] The heating component 8 includes a partition 5 fixedly arranged in the drying cylinder 1 at a horizontal interval, and a heating component 8 arranged at the bottom of the partition 5. The partition 5 is provided with a feed groove 7, wherein the upper and lower adjacent feed grooves 7 are staggered, and the feed grooves 7 of each layer are arranged along the radial direction, the feed grooves 7 are small at the top and large at the bottom, and the feed grooves 7 of each layer are arranged in sequence along the rotation direction. The stirring component 2 includes a motor 201, a reducer 202, and a through shaft 203, and the stirrer 204 is fixedly connected to the through shaft 203. The mixer 204 includes two toothed plates, and the tooth holes of the two toothed plates are arranged in a staggered manner. The heating component 8 includes a heat-conducting coil 801, which is installed in the partition 5. The heat-conducting coil 801 and the heat-conducting plate 6 are arranged correspondingly, and the heat-conducting plate 6 is heated by heat-conducting oil; the heat-conducting oil of the heat-conducting coil has an independent circuit for each layer, and the heat-conducting coil of each layer is independently arranged, and the temperature can be set separately according to the situation. It can also be partially or partially connected in series and parallel in actual use to achieve a gradual increase in temperature or fine temperature control at a local position.

[0028] The stirring component 2 includes a plurality of stirrers 204 arranged corresponding to the partition 5. The stirrer 204 is driven by the central axis of the partition 5 to rotate so as to push the material to the feed groove 7. The stirring component 2 also includes a feed bin 3 and a storage bin 4. The feed bin 3 and the storage bin 4 are both arranged on the drying cylinder 1. The angle of the feed groove 7 of each layer on the partition 5 is different. At least six partitions 5 are arranged. The width of the feed groove 7 is 5cm-10cm from top to bottom. The setting of small top and large bottom can effectively avoid blockage. At the same time, the distance between the upper and lower partitions is generally controlled at about 10cm, which can ensure effective stirring space.

[0029] Specifically, the working principle of the vertical recycled material stirring and heating device is as follows: when in use, the motor 201 works to drive the shaft 203 to rotate, the rotation of the shaft 203 drives the stirrer 204 to rotate, the heat transfer oil circulation system works to inject heat transfer oil into the heat transfer coil 801, and the recycled asphalt fine material is injected into the drying cylinder 1 through the feed bin 3. After each layer is heated, the recycled asphalt fine material falls layer by layer under the joint action of the stirrer 204 and the feed groove 7. The staggered arrangement of the toothed plates allows the fine material falling from the upper layer to be spread out, and then pushed down to the next partition again, and then During the working process of slowly heating the raw asphalt fine material layer by layer from top to bottom, the heat source of each layer is stable, and the heat transfer oil exchanges heat with the recycled asphalt fine material, so that the recycled asphalt absorbs heat evenly and the temperature rises gradually and steadily, avoiding direct contact of the recycled asphalt fine material with open flame and high temperature, and has the characteristic of protecting the recycled asphalt. The vertical recycled material stirring and heating device allows the recycled asphalt to absorb heat evenly and the temperature rises gradually and steadily, effectively preventing the recycled asphalt fine material from coking, that is, the heated recycled asphalt fine material will not adhere to the drying cylinder 1, bringing better user experience.
