Description

Vehicle-mounted movable type ship oil stain collecting and transferring system

Technical Field

The invention relates to the field of sewage treatment equipment, in particular to a vehicle-mounted mobile ship oil stain collecting and transferring system.

Background

Vessels can produce large amounts of domestic sewage and waste during operation, including sewage and waste from personnel or object cleaning processes, sewage and waste from cooking processes, and waste from personnel excretions processes. These contaminants typically flow into the domestic sewage storage tanks through the sewer system on the vessel. Because the ship cannot perform harmless treatment on living needs, the ship usually discharges pollutants in the domestic sewage storage tank after being supplied to the shore; or the sewage in the ship is pumped and transported by a special sewage transportation ship in the course of navigation.

Most of the existing ship sewage storage tanks are simple in structure, are only used as temporary pollutant storage containers, and can be used for sucking and discharging sewage through a fecal suction truck when in shore or transportation, so that the pretreatment of pollutants can not be performed. Domestic sewage often contains a large amount of organic matters, and biological fermentation of the pollutants in the storage tank can occur, so that a large amount of flammable and explosive gas is generated, and great potential safety hazards are brought to the storage process of the domestic sewage. Meanwhile, the solid matters in the sewage can be adhered to the inner wall of the container in the temporary storage process, so that the pipeline is blocked, and the sewage is not discharged. Meanwhile, the existing sewage storage tank needs personnel to watch the sewage storage tank periodically to check the internal reserves, and special personnel are also needed to watch and operate in the sewage discharge process.

Besides the sewage storage facilities on the ship, there are also disadvantages of the sewage transfer and collection devices on the shore. For example, existing on-shore sewage collection and transfer are mainly completed through a manure suction vehicle, and the manure suction vehicle needs to be in butt joint with a sewage storage tank on a ship through a pipeline when in use, and the pipeline is recovered after sewage discharge storage is completed. The existing pipeline release and recovery are mostly completed by manpower, which is time-consuming and labor-consuming, messy and bad, and sewage leakage can be generated, so that pollution is caused to a ship body, a water body, a embankment or a wharf.

In the process of collecting and transferring the ship sewage, the automation degree of various related equipment is relatively low, manual operation and butt joint are needed, and flow statistics, cost settlement and the like are performed manually. These greatly reduce the efficiency of the sewage collection and transfer work, and the inefficiency is reflected in the high cost of sewage collection and transfer.

The sewage recovery, transfer and treatment costs are high, so that illegal and illegal actions such as disordered arrangement and arrangement occur in part of shipping enterprises. If the pollutants on the ship are discharged into the water body, serious water pollution accidents can be caused. Therefore, governments in various places in China are required to comprehensively plan and accelerate the construction of onshore fixed receiving facilities and water flowing receiving capacity; the ship pollutant receiving system taking the shore fixed facility receiving as a main body and the water flowing receiving as a supplement is gradually formed, the ship pollutant receiving capacity of the areas such as the ports and the wharfs in the jurisdiction is comprehensively improved, the 'fully received' is achieved, and the effective connection of the links of receiving, transferring and disposing the ship pollutant is well achieved. Despite the huge sewage collection and transfer demands, the running efficiency, safety and the like of the existing ship sewage collection and transfer system and equipment are obviously insufficient, the automation degree of the equipment is low, a plurality of operators are needed to participate in the treatment in the sewage recovery treatment process, and the performance of the equipment cannot meet the market demands.

The transmission mechanism allows the first stand-alone to drive the rotation of both the drum 46 and the screw 58 simultaneously, and the rotational speed of the screw 58 and the drum 46 is not constant because the drum 46 varies with the outer diameter of the combination of the drum 46 and the hose 44 during the process of transceiving the hose 44, so the rotational speed of both is adjusted and adapted by the gear ratio and the speed reduction of the sprocket.

In this example, the third controller 66 is further connected to a third communication module 77, where the third communication module 77 is configured to communicate with external equipment or a system, obtain a volume of sewage or oil to be transported on the ship, and receive an operation instruction sent by the external equipment or the cloud system.
