When changing the materials in the Vibrating Spiral Elevator, it is very important to thoroughly clean the spiral conveying layer. This step is not only related to the efficient operation and long-life maintenance of the equipment, but also directly affects the purity and processing quality of the subsequent materials.

The spiral conveying layer is a key area for material transmission, and its surface state directly affects the fluidity and adhesion of the material. Due to the diverse designs of the spiral conveying layer, including water-cooled layer, air-cooled layer and ordinary conveying layer, each mode has different functions, but it is necessary to maintain the smoothness and cleanliness of the surface to ensure the transmission efficiency.

Due to differences in edge pressing technology, the ordinary conveying layer is prone to unevenness, which not only increases the risk of material residue, but also may cause blockage or uneven distribution of materials during transportation, thereby affecting production efficiency. Even under the drive of the vibration motor, the material can rise along the spiral trajectory, but for granular materials, its surface tension and the interaction force between particles can easily cause the material to be retained on the surface and gaps of the conveying layer, forming a residual layer that is difficult to fall off naturally.

Therefore, cleaning the spiral conveying layer before changing materials can remove the residue of the previous batch of materials, avoid cross-contamination between different materials, and ensure the purity and processing accuracy of the new materials. Sanyuantang recommends physical cleaning methods such as towel-assisted lifting, air pump blowing or vacuum cleaner vacuuming, which can effectively remove the residual materials on the spiral conveying layer and restore its smooth surface.

The specific cleaning steps are as follows:

First, before the vibration elevator enters the shutdown procedure, carefully lay a soft and wear-resistant clean towel that has been pre-treated (such as soaking to increase adsorption but avoid excessive moisture to cause material adhesion) at the starting position of the conveyor disc. As the vibration motor starts, the towel will gradually move upward with the vibration of the spiral conveying layer, and its surface will absorb and carry most of the materials up together.

When the towel approaches the discharge port, the operator should intervene quickly and safely, and use special tools (such as clamps, etc.) to smoothly remove the towel from the conveying path to ensure that the material on the towel can fall into the preset collection container, thereby minimizing the residue of the material on the conveying layer.

Subsequently, a high-efficiency air pump can be used to blow away the small amount of material that may remain on the spiral conveying layer. The air pump should be adjusted to an appropriate pressure, and its nozzle should be precisely aimed at the surface of the conveying layer and the hard-to-reach gaps, using high-speed airflow to completely blow the remaining material down to the feeding plate area. During this process, it is necessary to ensure that the air pump is operated safely to avoid unnecessary impact or damage to other parts of the equipment by the airflow.

As an alternative, for occasions with extremely high cleanliness requirements or extremely fine residual materials, a small industrial vacuum cleaner can be used for fine cleaning. The vacuum cleaner should be equipped with a nozzle and filter system suitable for the occasion to effectively remove tiny particles and dust on the conveying layer. During operation, the vacuum cleaner should be kept at an appropriate distance from the surface of the conveying layer to avoid damaging the surface of the conveying layer or causing clogging of the vacuum cleaner.
