Description

Cleaning dust suppression system of middle-drive belt conveyor Technical Field The invention belongs to the technical field of bulk material transportation, and relates to a cleaning dust suppression system of a middle-drive belt conveyor. Background In the bulk material conveying process, part of conditions are limited by process conditions, the belt conveyor needs to adopt a transmission mode of middle driving, bulk materials can be adhered to the upper part of the conveyor belt in the conveying process because the conveyor belt is made of flexible materials, and meanwhile, the middle driving device arranged on the bottom layer platform can enable the conveyor belt to be tensioned and vibrated suddenly in the starting and running process because the conveyor belt is made of flexible materials, so that the bulk materials adhered to the conveyor belt form dust and spread into the environment, and environmental pollution is caused. Currently, most existing mid-drive devices are installed in enclosed buildings, with the intention of reducing the impact on the external environment. However, the portion of the drive belt from the upper deck to the lower deck is typically in an open form and no effective dust suppression measures are taken. This causes a more serious problem in that dust adhering to the conveyor belt spreads to the inside of the building without hindrance when the intermediate drive is suddenly started or is operating normally. The space in the building is relatively closed, and once the dust is generated, the dust is difficult to rapidly spread and dissipate, and a large amount of dust can be accumulated indoors. The dust diffused in the building not only can pollute and abrade indoor equipment and facilities and reduce the service life and the operation efficiency of the equipment, but also can pose serious threat to personnel working in the equipment. When the dust collector is exposed in a dust-raising environment for a long time, operators easily inhale a large amount of dust, and health problems such as respiratory diseases, pulmonary diseases and the like are caused, so that the operation safety and the physical health of the operators are seriously affected. Therefore, aiming at the series of technical problems generated in the operation process of the bulk conveying middle driving device, an effective solution is urgently needed to be provided so as to improve the operation environment, ensure the health and safety of personnel and realize the green and sustainable development of industrial production.
