Wuhan Junwei AC Series Air Purge Cleaner is a non-contact cleaning equipment specially developed for fine cleaning of the surface of belt conveyors. Based on the Coanda effect principle and special flow channel structure design, it can form a high-intensity and high-uniformity linear impact air curtain to efficiently remove dust and fine particulate materials attached to the surface of the conveyor belt. Compared with traditional sweepers, it completely solves industry pain points such as belt scratches, blade wear, cracks and potholes cleaning blind areas, and is the preferred cleaning solution for powdery and fine-particulate material transportation scenarios.
The air outlet effect of the product is more than 30% higher than that of traditional sweeping air nozzles, and the energy consumption is 40% lower than that of ordinary nozzles; the air outlet can be freely adjusted, the air flow is uniformly and linearly output, and the operation is without vibration and low noise (65-80DBA). The structure is simple and strong; it comes with a high-pressure air source, and can flexibly configure a wind pressure of 50~290mbar according to on-site conditions. It can realize interlocking control with the conveyor and adapt to various automated conveying systems.
The products are widely suitable for conveying powdery and fine particulate materials such as mines, building materials, chemicals, grain, and electricity. They can be perfectly used with primary and secondary mechanical cleaners to form a full-process cleaning system of "mechanical rough sweeping + air fine sweeping"., completely solving the problem of residual materials and dust spillage from the belt.

Product core structure
working principleThe product is designed based on the core principle of the Coanda Effect. When the compressed air generated by the high-pressure fan enters the cleaner nozzle, it passes through a special flow channel structure to form a linear primary air curtain blown out at high speed; this air curtain is deflected by 45° to both sides from the outlet blade, which can divert 25-40 times of ambient air, and finally form a thin, high-intensity impact air curtain, with an air flow speed of 70 - 150m/s.
The high-intensity continuous air curtain can efficiently strip off the dust and fine particulate materials attached to the surface of the conveyor belt. Part of the material dropped by the blowing falls directly into the conveyor hopper. The remaining dust is sucked away by the negative pressure of the on-site dust removal system, achieving no residue, Efficient cleaning without secondary dust and completely solves the problem of cleaning blind areas of traditional cleaners.
core technology advantagesThe non-contact cleaning method of air blowing is adopted. There is no hard contact between the scraper and the belt. It will not cause any wear or scratch on the belt and joints. It is perfectly suitable for the conveyor belt with cracks, potholes, and patterned surfaces, completely solving the problem. Blind areas on the belt surface that cannot be cleaned by traditional cleaners greatly extend the service life of the conveyor belt.
The optimized flow channel design based on the Coanda effect improves the air outlet effect by more than 30% compared with traditional purging air nozzles, and the energy consumption is reduced by 40% compared with ordinary nozzles; the air outlet can be freely adjusted, and the air flow is uniformly and linearly output, forming a continuous and uninterrupted impact air curtain without a purging blind area. Even fine dust can be completely removed, and the cleaning efficiency far exceeds that of traditional purging solutions.
There are no easy-to-wear parts such as blades and rubber strips, there is no problem of frequent replacement of consumables, and there is no need for regular tension adjustments. Daily operation only requires simple air supply inspection to operate stably, greatly reducing equipment operation procurement costs and manual maintenance costs; The overall structure is simple and strong, vibration-free, low-noise operation, and its service life far exceeds that of traditional mechanical cleaners.
It comes with a high-pressure air source, which can provide a wind pressure of 50 - 290bar. It can be flexibly configured according to on-site working conditions to adapt to conveying scenarios with different bandwidths, different belt speeds, and different material characteristics; it can be interlocked with the conveyor and started and stopped randomly without manual operation; a remote control module can be optional, which can be connected to the centralized control system of the factory area to adapt to the upgrade needs of the intelligent conveying system.
