Background
Known, in the production process in the fields of building materials, metallurgy, mines and the like, the condition of multipoint blanking of a belt conveyor movable type discharging trolley is often involved, and the discharging trolley often generates larger raised dust during discharging. At present, the following two methods are generally adopted for eliminating the dust at each discharging point: 1. one dust collector is independently and fixedly arranged, and multi-point dust collection is intensively carried out through a dust collection pipeline; 2. and a spraying device is arranged above the discharging point, and dust is reduced by utilizing atomized water vapor.
In the first mode, the discharge trolley isWhen the material is unloaded at an indefinite point, and dust is collected from a plurality of blanking points by adopting the method of independent fixed arrangement and concentrated dust collection of the dust collectors, the unreasonable arrangement that the system pipeline is too long, the angle of the dust collection pipeline is too small, and even all the dust collection pipelines are horizontal angles exists. In the actual production process, the synchronous operation of unloading and dust collection can be realized by means of an electric regulating valve and an automatic control system. Due to the fact that the dust collecting system is too long in pipeline and small in arrangement angle, dust accumulation in an air pipe is serious and wind resistance is larger and larger after the dust collecting system is used for a long time, the dust collecting effect is reduced, the dust collecting pipeline is completely blocked when the dust collecting system is serious, and raised dust in the whole working place is large and reaches 100g/Nm3Therefore, the working environment of field workers is severe, and the body health of workers is seriously affected.
In the second mode, although the atomized water vapor can play a role in dust suppression and dust fall, the atomizing device has high standard requirements on water quality, and the nozzle is easy to block if the water quality is poor; particularly in severe cold areas, when the water spraying device is operated in winter, the water spraying device can freeze materials, and in severe cases, the belt and the materials can be frozen, so that the production is seriously influenced.
