Problems solved by technology

Once the hopper is blocked, it will greatly affect the normal operation of the grab ship unloader
At the same time, the manual cleaning required after the hopper is blocked adds a lot of work burden to the operation and maintenance of the wharf, and also causes a large increase in the operation and maintenance costs of the wharf. Research and analysis of the phenomenon, adopting a reasonable hopper anti-blocking material control method greatly reduces the risk of material hopper blockage of the grab ship unloader, thereby ensuring efficient and reliable operation of the equipment

Embodiment

[0056] Taking the grab ship unloader equipped with bucket wall vibrator, air cannon and belt scale as an example, the anti-blocking function of its hopper is explained. control flow such as Figure 8 Shown: After the hopper anti-blocking function is applied, the PLC control unit firstly confirms the operating status of the air cannon, hopper door and bucket wall vibrator in the blocking treatment system. If it is confirmed that the operation is normal, the hopper anti-blocking function will be activated. activation. After the hopper anti-blocking function is activated, the PLC control unit will monitor the material blockage in the hopper area in real time. When the material blockage warning system of the hopper has a blockage warning (the blockage detection switch is activated, the material flow of the belt scale is abnormally reduced, and the decreasing trend of the hopper weight disappears) When the PLC control unit issues an instruction, the hopper blockage processing syst...

Abstract

The invention discloses an anti-clogging material system for a hopper of a grab ship unloader, comprising an early warning unit for hopper blockage which is arranged in the hopper and feeding area of ​​the grab ship unloader, detects whether the hopper is blocked and monitors the actual operating condition of the material flow; A PLC control unit that receives the material blocking status and the actual operating status of the material flow transmitted by the hopper material blocking warning unit, and the PLC control unit reads the belt scale working status signal, hopper weighing signal and material blocking from the received information. Detect the switch signal, and judge whether the blockage detection switch action is abnormal, whether there is a downward trend in the weight of the hopper, and whether the material flow signal of the belt scale is abnormal. Corresponding operation instructions; a hopper blocking processing unit that receives the control instructions transmitted by the PLC control unit, and the hopper blocking processing unit performs dredging processing on the blocking condition of the hopper mouth.

Description

technical field [0001] The invention relates to the field of port bulk material loading and unloading machinery control, in particular to an anti-blocking material system for a hopper of a grab ship unloader. Background technique [0002] For port bulk material handling machines such as grab ship unloaders equipped with hopper mechanisms, due to the physical characteristics of bulk materials, especially when the material moisture content is large, the hopper mouth area is prone to material blockage. Once the hopper is blocked, it will greatly affect the normal operation of the grab ship unloader. At the same time, the manual cleaning required after the hopper is blocked adds a great workload to the operation and maintenance of the wharf, and also causes a large increase in the operation and maintenance cost of the wharf. Therefore, it is necessary in this field to block the hopper of the grab ship unloader. The phenomenon is studied and analyzed, and a reasonable hopper ant...
