*calculated in accordance with the technical characteristics of the conveyor and the cargo flow
Water is supplied from the fire-extinguishing tower with the addition of wetting concentrate from tank 8. As the transported mass moves along the conveyor belt, a slight sag of the belt occurs, and at this moment the wheel of the control irrigation device 4 contacts the belt and begins to move. When a certain wheel speed is reached, a valve inside the control irrigation device 4 opens, and water is supplied through flow regulator 2, filter 1 and injector unit 3, in which water is automatically mixed with wetting concentrate to pre-irrigation and humidification device 5. When water is supplied to injector unit 3, a vacuum pressure is generated in it, and the emulsion concentrate is sucked from tank 8 by self-priming. The concentration on the injector unit is adjusted by adjusting the throttle. When the conveyed material reaches the vertical control valve 7, it is activated to supply water or emulsion to the direct irrigation device 6, thereby irrigating the immediate transfer point. When there is no material on the conveyor belt, there is no contact with the vertical valve 7, no slack in the belt, and therefore no contact with the control device wheel. Thus, the water supply is stopped, enabling automatic operation of the automatic dust suppression system (ADS).
Automatic transmission system components
Injector unit ASPP.04.000
The injector unit is designed to effectively mix feed water with concentrate. When water is fed into the injector unit, the concentrate is automatically drawn in by vacuum. This is followed by uniform mixing in the mixing tube until a homogeneous emulsion is achieved. The emulsion concentration can be adjusted within a range of 1-10% using the adjustment device installed on the injector unit. Flow rate up to 250 l/min.
Technical specifications
Working pressure 5-50 bar Quick coupling connection:
water inlet nipple - OM 20
Concentrate input socket - OM 12.
emulsion outlet socket - OM 32
Control irrigation device ASLP.01-000
The control irrigation device is installed on the belt conveyor stand under the belt 10 meters from the conveyor drive drum and is connected to high-pressure hoses M1 2 nipple.
Operating principle
The ASPP.01.000 control irrigation device is designed to monitor the transported material on a conveyor belt. As the material moves along the conveyor belt, a slight sag occurs, causing the wheel of the control irrigation device to contact the belt and begin to move. When a certain wheel speed is reached, a valve inside the control irrigation device opens, dispensing water or emulsion.

Control device ASPP.07.000
The control device ASPP.07.000 is designed to supply or cut off water (emulsion) and is installed rigidly above the belt conveyor 0.5-1 meter before the transfer point.
Operating principle
When transporting the mass, a control device is activated and water is supplied. It is connected to the fire-fighting system using OM12 high-pressure hoses. Recommended pressure is from 5 to 50 bar.
Filter ASPP.03.000
The ASPP:03:000 filter is designed to filter water supplied from a fire-fighting tower. The filter element is flushed by opening the ball valve. Filtration rating: 500 µm.
Flow regulator ASPP.02.000
The ASPP.02.000 flow regulator is designed to regulate water flow for an irrigation system. Adjustment is made by opening or closing the valve.
Operating principle
This equipment is conveniently mounted on a belt conveyor line and connected to a fire-fighting line via 2M12 high-pressure hoses. Recommended pressure ranges from 5 to 50 bar. Capacity up to 100 ^/min.
