Taizhou water-soluble fertilizer production line Taizhou water-soluble fertilizer production equipment

Description :

　　On the platform, materials are manually or transported to the feeding port. A small amount of pre mixed materials are manually prepared and directly fed into the pre mixed material bin through the feeding port. The feeding port is equipped with a reserved DN200 material inlet with a flange short circuit, a dust collector interface on the top of the bin, and an anti dust bag opening station and dust removal system.

　　working principle

　　3.1 The powdered raw materials in bags are manually moved to the feeding port, the feeding port movable door is opened, the bag opening station fan is started, and air suction or other conveying devices are used to feed the materials from the feeding port into the raw material storage bin. The suspended dust is adsorbed on the filter bag, and over time, more and more dust accumulates on the filter bag, increasing the resistance of the filter bag and reducing its passability. At this time, the PLC control system starts the pulse valve according to the thickness of the material on the filter bag, triggering the opening in sequence. The compressed air in the air bag is instantly sprayed through the pulse valve to each hole of the spray pipe, and then sprayed into the corresponding filter bag through the pipe; The filter bag rapidly expands under the reverse action of the airflow, causing the material dust accumulated on the filter bag to fall off, regenerating the filter bag, and the cleaned material to fall into the lower box. The dust accumulated on the filter bag is periodically removed by pulse blowing, ensuring good passability of the filter bag and continuous operation of the dust removal system.

　　3.2 Adding a pulse dust removal system to the powder feeding port can solve the problem of dust flying and environmental pollution caused by powder feeding, ensuring a good working environment.

　　The equipment composition of the bag opening station includes: feeding port, discharging port, fan suction system, bag filter, pulse blowback system, electrical control system, etc.
