[0004] The aforementioned patent proposes that the recycled powder can be broken down and screened to remove impurities, making the recycled powder finer. However, during the use of the recycled powder processing device in the asphalt mixing plant, the screen plate is easily clogged when the recycled powder is relatively wet, as the humidified recycled powder is removed by the screen plate, which affects the sieving of the recycled powder. Utility Model Content

[0005] The purpose of this invention is to provide a recycling powder processing device for asphalt mixing plants, in order to solve the problem mentioned in the background art that when the recycled powder is relatively wet, it is easy to cause clogging of the screen plate, which affects the sieving process of the recycled powder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an asphalt mixing plant recycled powder treatment device, including a support base and a treatment structure installed on the upper end of the support base. The upper end of the treatment structure is equipped with a feed pipe for the recycled powder to enter. The upper end of the support base is also equipped with a humidification structure, which is located on one side of the treatment structure. The recycled powder is moistened by the humidification structure and treated in conjunction with the treatment structure.

Several nozzles are evenly distributed on the surface of the air jet pipe. The nozzles are used for gas ejection, and the filter screen is placed outside the nozzles.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The system includes a support base, processing structure, feed pipe, and humidification structure. The recovered powder is fed into the processing tank through the feed pipe. The humidification structure wets the powder. When the motor is started, it drives the rotating shaft, which in turn rotates the screen plate, stirring rod, and scraper, agitating the recovered powder. The screen plate then filters out impurities. Simultaneously, air is blown upwards from below the screen plate using a clearing device to agitate the wet powder and clear the sieve holes, preventing blockage and ensuring proper sieving. A filter screen also prevents wet powder from entering the nozzles, maintaining smooth airflow.

[0013] 2. The triangular plate and the unblocking rod are used to assist in agitating the wet powder on the screen plate, which is conducive to sieving. The airflow, the unblocking rod and the stirring rod work together to agitate the wet powder, which can maintain the fluidity of the wet powder and prevent clumping. Attached Figure Description
