Description

TECHNICAL FIELD

[0002] Floating suction type salt collection is a common salt collection method in salt industry production, which needs to use a specific floating suction type salt collection device. The device includes a power device, a salt collection device and a salt conveying device. The power device usually adopts a track type salt collector power device. The salt collection device is composed of a hydraulic lifting device and a salt collection bucket. The salt conveying device is composed of a connecting elbow, a mud pump, a universal joint pipe and a plastic hose. The feature of this method is that the discharge port of the salt collection bucket is connected with the suction inlet of the mud pump through the connecting elbow, and the outlet of the mud pump is connected with the plastic hose for conveying salt brine. The plastic hose is partially supported by a floating net in the brine pool and floats on the brine surface. In this way, the salt and brine mixture is sent to the collection point in the plastic hose and then separated and fed into the storage bin, thereby completing the salt collection process. This salt collection method has the advantages of simple structure, convenient use and maintenance, low maintenance cost, fast mechanical movement and the ability to cover rain and increase the amount of salt in the storage bin when it rains.
