Description

Technical Field

[0001] The invention relates to the technical field of gneiss asphalt mixture, in particular to an improved powder feeding device for producing gneiss asphalt mixture. Background Art

[0002] The types of diseases on green road surfaces include oil spills, cracks, rutting, looseness, etc., and the presence of water will inevitably accelerate the formation and development of various types of diseases, which is the water damage of asphalt pavement. Among many controllable factors, the rock properties of aggregates have the greatest impact on the water stability of asphalt mixtures. Acidic aggregates such as gneiss, granite and sandstone are not widely used in highway construction due to their poor adhesion to asphalt. In some areas rich in acidic stones, if we still blindly pursue the use of alkaline and neutral stones, it will inevitably increase the project cost and extend the construction period. In this case, we should actively find ways to use local materials, adapt to local conditions, and make rational use of local stones, which not only reduces the project cost, saves money, shortens the construction period, but also drives the development of the economy along the line. The two combined improvement methods of replacing slaked lime and limestone fine aggregate can significantly improve the various road performance of gneiss asphalt mixtures, so that they can meet the actual engineering application requirements. The optimal amount of slaked lime is 1% of the total amount of the mixture.

[0003] When the existing improved powder feeding device is in use, the powder tank for producing gneiss asphalt mixture in the asphalt mixing plant has problems such as difficulty in unloading and easy to get damp and agglomerate during use. The reasons are as follows: 1. The plug-in partition is not sealed enough, which is easy to cause rainwater and water vapor to penetrate and cause agglomeration, affecting the unloading of materials. 2. The opening of the plug-in partition is not easy to adjust, because the adjustment stroke screw hole on the plug-in partition has been set to a fixed value. If the opening is too large, it is easy to block the auger. If the opening is too small, it is easy to cause material accumulation on one side and hollowing on one side. It is not easy to adjust. In addition, the plug-in partition is not sealed enough and needs to be sealed with glue after adjustment. The next adjustment needs to be cut off with a utility knife to remove the sealant before disassembly, which is not conducive to quick adjustment. For this reason, we propose an improved powder feeding device for gneiss asphalt mixture production to solve the above problems. Summary of the invention

[0004] In view of the above problems, the present invention proposes an improved powder feeding device for producing gneiss asphalt mixture. The improved powder feeding device for producing gneiss asphalt mixture mainly utilizes the third motor, the middle shaft and the impeller blades installed on the impeller feeding component to achieve a rigid impeller feeder with no sliding loss in speed and almost no loss in transmission efficiency during output transmission. The rigid impeller feeder allows a larger transmission ratio. The rigid impeller feeder can transmit greater power at low speed and can work under higher temperatures or other harsh conditions. It has a compact structure, transmits the same power, and has a smaller outline size. The rigid impeller feeder has high separation efficiency and small equipment resistance. The performance of the rigid impeller feeder is stable, and the discharge is uniform and continuous. When the conveying conditions change, it must also have stable separation capabilities. The rigid impeller feeder has a simple structure, easy maintenance and manufacturing, and a long service life. The parts that are easily worn can be disassembled and replaced. It is best to have more transparent parts for observation and operation. When the material is not discharged smoothly, a micro vibration pump is used to vibrate, so that the material is not easy to clump and the powder is easy to flow, so that the powder can quickly pass through the impeller feeder and go down to the auger for production, which can significantly improve production efficiency.
