粉を除去する清掃装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning an air-floating conveyor. In air-floating conveyors,
When the scraping efficiency of the belt cleaner is reduced, the powder of the transported material adhering to the belt surface cannot be completely scraped off, and whenever the belt comes into contact with the trough, or the belt vibrates slightly, the powder in the trough falls and the transport time is reduced. As the process progresses, the powder falling may also grow and grow, thereby closing the air blowing holes.
If the clogging occurs, a uniform air film cannot be formed between the belt and the trough, and the belt and the powder fall into contact with each other, which wastes power and wears the belt. The present invention relates to a cleaning device for removing such powder fall.

とって好適な洗浄が行える。According to the first aspect of the present invention, during normal operation of the conveyor, air for levitation is blown out from the air outlet to form an air film between the belt and the trough, and the belt is run. If air blowing holes are clogged or accumulated due to powder falling during normal operation, high-pressure air from a high-pressure air supply source is injected into the air duct through high-pressure air piping, causing impact around the air blowing holes. To blow off deposits. Further, if the washing water is guided from the washing water supply pipe into the air duct and flows from the washing water drain pipe, powder falling in the air duct can be discharged outside the machine. Claim 2
According to the invention, during normal operation, by opening the on-off valve on the inlet side of the pressure reducing valve of the low-pressure circuit in the high-low switching circuit and closing the on-off valve of the high-pressure circuit, the air duct has an appropriate low pressure to float the belt. When air is supplied and the on-off valve of the low-pressure circuit is closed and the on-off valve of the high-pressure circuit is opened, high-pressure air is supplied to the air duct, and the powder around the air outlet is blown off and removed. After that, the falling powder may be washed away with washing water. According to the third aspect of the present invention, the pressure in the air duct can be detected at any time, and the pressure in the air duct increases when the powder falling blocks the air blowout hole. The necessary time can be grasped appropriately. According to the fourth and fifth aspects of the present invention, powder falling around the air outlet can be sucked and collected in a vacuum car outside the machine, and in this case, there is no need to wash away with washing water. Therefore, it is possible to perform cleaning suitable for a conveyor that conveys cement, ash, or the like that dislikes moisture.

In addition, if cleaning water is guided from the cleaning water supply pipe into the air duct and flows from the cleaning water drain pipe,
Powder falling in the air duct can be discharged outside the machine.
According to the invention of claim 2, during normal operation, if the on-off valve on the inlet side of the pressure reducing valve of the low-pressure circuit in the high-low switching circuit is opened and the on-off valve of the high-pressure circuit is closed, the air duct is suitable for lifting the belt. When low-pressure air is supplied and the on-off valve of the low-pressure circuit is closed and the on-off valve of the high-pressure circuit is opened, high-pressure air is supplied to the air duct, and the dust from the air blowout holes is blown off and removed. After that, if the dust in the air duct is washed away with the washing water, the dust can be discharged outside the machine. According to the third aspect of the present invention, the pressure in the air duct can be detected at any time, and the pressure in the air duct increases when the powder falling blocks the air blowout hole. The necessary time can be grasped appropriately. According to the fourth and fifth aspects of the present invention, powder falling around the air outlet can be sucked and collected in a vacuum car outside the machine, and in this case, there is no need to wash away with washing water. Therefore, it is possible to perform cleaning suitable for a conveyor that conveys cement, ash, or the like that dislikes moisture.
