Ship loader

الوصف

Ship loaders are large bulk material machines used for loading at bulk material terminals. Generally, ship loaders are composed of arm belt conveyors, transition belt conveyors, telescopic chutes, tail cars, running devices, gantry, towers, pitch devices, slewing devices, and slewing devices.
Ship loaders can be divided into track loaders, telescopic loaders, swing loaders, fixed loaders, bulk loaders, and arc swing loaders according to the use method, as shown in Figure 1. Large port bulk material loading equipment plays an important role in the high-speed, stable, efficient, and rolling development of some large bulk material distribution centers in the energy, power, metallurgy, and ports industries. Ship loaders are usually continuous loading operations. Therefore, there must be matching equipment to provide continuous material flow so that the ship loader can load continuously. Such as feeding grain silos at grain terminals and continuous feeding of bucket wheel reclaimers in the material yard of coal terminals.
The development of global trade integration has promoted the demand for bulk transportation worldwide. From the perspective of major commodities, the seaborne volume of bulk cargoes such as iron ore, coal, and grain has increased rapidly. Accompanying this development is the continuous renewal of ocean-going bulk cargo transport ships. What follows is the demand for bulk cargo loading and unloading equipment for the construction of large ports that can dock and unload these large ships. The increase in the size of bulk cargo ships also poses new challenges to the design and manufacture of bulk cargo loading and unloading equipment. According to the development trend of bulk cargo automation, some development trends of ship loaders can be predicted.
Product Features:
Automation
Dry bulk cargo terminals have different characteristics of cargo to be loaded and unloaded, and there are many types of ships. In addition, the operating environment is relatively harsh when affected by bulk cargo dust, and there are more stringent requirements for detection equipment and technology. Therefore, the current bulk cargo loading system has a low degree of automation and basically relies on manual on-site operation. On the one hand, the use of on-site manual operation will endanger the physical and mental health of on-site workers due to the harsh working conditions (high temperature, high dust, high noise, etc.) of bulk cargo terminals. On the other hand, due to the harsh working conditions and long-term cargo loading, it is very easy to cause worker fatigue and cause accidents during loading. In addition, due to manual loading, the operation process will be irregular and unscientific. For example, to avoid collision, the chute is suspended above the cabin, causing dust and cargo loss. Since berths are scarce resources at the terminal, the loading process of bulk cargo terminals has become one of the bottlenecks restricting bulk cargo logistics, and an automated loading system is urgently needed. Therefore, one of the development trends of ship loaders in the future is the degree of automation.
Large-scale
Large-scale loading equipment accounts for an increasing proportion. At present, the productivity of ore loaders in the world is as high as *0,**0t/h, and the outreach is suitable for **0,***-ton ships.
Specialization
The different transport materials (such as coal, ore, cement, grain, fertilizer, etc.) make the design of loading equipment more and more specialized, such as explosion-proof, anti-corrosion, dust-proof, and anti-pollution design requirements, and the design standards are becoming more and more perfect. Foreign companies select fixed rotary, mobile rotary, and mobile non-rotary models according to the actual working conditions of materials, terminals, and ship types, and put forward an overall plan. The models used in my country are limited to mobile rotary and mobile non-rotary.
Environmental protection
Environmental protection is the premise of development. The development and application of effective methods such as mechanical seals, water mist dust suppression, air flow guidance or blocking, and the setting of an independently operated dust-proof aggregate system have become one of the research topics in the design of modern ship loaders. For example, the popularization and application of tubular belt conveyors, fully enclosed structures, and dust-proof chutes have greatly improved the dust-proof effect. In order to adapt to the increasingly stringent environmental protection requirements and pursue harmony with the environment, we continue to strengthen the technical development of equipment in terms of dust prevention, corrosion prevention, low noise, and pollution-free.
