Working principle of mobile screw ship unloader

Screw ship unloader manufacturers talk about the working principle of mobile screw ship unloader. The flow direction of materials in the unloading process of screw ship unloader manufacturers is as follows:

1) The materials in the cabin enter the vertical screw conveyor through the relative rotary feeding device (screw feeding head).

2) The material continuously enters the pipe of the vertical screw conveyor and is lifted to the end of the boom, and is transferred to the boom horizontal screw conveyor through the discharge port.

3) The material enters the transfer funnel in the center of the rotating tower along the boom.

4) Finally, the materials are transferred to the belt conveyor of the front closed corridor parallel to the wharf through the horizontal screw conveyor on the gantry.

Spiral ship unloader uses Archimedes axial equal spiral pipe to transport bulk cargo. It can carry out continuous unloading operation of various bulk cargoes on one equipment, so it is also called multi-purpose continuous ship unloader. The parts and mechanisms of screw ship unloader from the cabin, out of the cabin and on shore are connected into one. During the unloading operation, the bulk cargo is transported in a flowing state, which realizes the real continuous operation. The goods flow in a closed pipe (usually a cylindrical barrel), so it can effectively prevent the goods from being polluted and ensure that the goods do not pollute the environment. When the equipment is working, it can be operated by remote control, and the operator can also choose to operate in the cab. Under the action of air conditioning, it can ensure that the indoor temperature is appropriate, and at the same time, it can avoid the contact between human body and cargo pollution, so as to realize the effective protection of labor. Its perfect solution makes the spiral continuous ship unloader become the landmark equipment of modern bulk cargo terminal.

The structure of the screw ship unloader is as follows: the vertical arm assembly is equipped with a vertical conveying spiral tube, whose basic shape is cylindrical barrel, and the main feature of the structural form is that the circular tube has an equal pitch spiral shaft. The vertical conveying screw feeding head of the vertical arm assembly excavates the materials from the cargo hold, and the lifting screw is responsible for lifting the materials into the vertical screw conveyor. The materials are transferred to the horizontal conveying screw through the vertical screw top transfer bin, and then transported to the gantry screw and the rear belt conveyor through the horizontal screw conveyor, and finally to the rear yard or warehouse. The feeding head of the screw ship unloader is a part that contacts and processes materials in the cargo hold, and it is also the core and key part of the ship unloader. The third is the 720mm long lifting screw at the bottom. The screw is made of special materials with high wear resistance index, which can maintain long-term and efficient wear in the material. The material from static to high-speed operation is done through the lifting screw, and works in the screw body through inertial speed until the material is transported to the belt conveyor through vertical screw, horizontal screw and gantry screw Reach the designated point. The characteristics of equipment conveying mode are very obvious - screw conveying. Based on this screw conveying mode, it can be clearly distinguished from other ship unloaders, so the screw ship unloader is named after it.
