Automatic following watering dust-suppression device for gantry crane coal work

Abstract

The invention discloses an automatic following watering dust-suppression device for gantry crane coal work. The device is characterized in that the device comprises an air curtain system and a water curtain system which are arranged on a rack platform, a water-collecting tray arranged on a rotary platform, and a watering device arranged on the end of a trunk beam; the air curtain system comprise several air curtain machines, which are arranged along the epitaxy of the rack platform to form a circle; a position sensor is arranged at an air outlet of each air curtain machine; the position sensor is connected to a control system of the rotary platform; and working condition of each air curtain machine in the air curtain system follows the rotary platform and is consistent with working position. Dust-suppression treatment is conducted by combining the watering device at the end of the trunk beam and the water and air curtains on the rack platform. The air curtain forms isolation; the water curtain runs to remove dust; and with the combination of the watering device, a good effect can be achieved.

Description

technical field [0001] The invention belongs to the dust suppression technology for port loading and unloading equipment, in particular to a dust suppression device for automatically following the coal operation of a portal crane. Background technique [0002] Portal cranes are widely used in port loading and unloading work because of their good versatility and various types of cargo that can be loaded and unloaded. However, when using portal cranes for coal and other bulk cargo operations, it is often accompanied by relatively serious dust pollution problems. At present, bulk cargo loading and unloading terminals in ports mostly install spray guns on the storage yard and the ground of the terminal to suppress dust by spraying water on the cargo stacks. Although this method can achieve a certain dust suppression effect, it also has some shortcomings: 1. The dust suppression range is small, and it is impossible to achieve three-dimensional, full-coverage dust suppression. G...

AI Technical Summary

Problems solved by technology

Although this method can achieve a certain dust suppression effect, it also has some shortcomings: 1. The dust suppression range is small, and it is impossible to achieve three-dimensional, full-coverage dust suppression

The dust suppression spray gun on the ground is easily affected by objective factors such as position and water pressure, and has insufficient ability to suppress dust during the process of picking up and discharging materials by the door machine and the operation of the door machine grab bucket.

2. Water resource utilization efficiency is not high

Due to the relatively single control function of the ground sprinkler and dust removal equipment, on-demand sprinkler and dust suppression operations cannot be carried out according to the operation of the equipment, resulting in unsatisfactory dust suppression effects and low water resource utilization efficiency

In open and semi-open unorganized discharge occasions, dust suppression and dust removal are generally adopted by dry fog and mist sprayer dust removal. Dry fog and fog particles are small, but due to the limited fog length, dust suppression cannot be achieved by using such methods in some places Function; the mist sprayer is generally a long-range sprayer with large fog particles, large water volume and strong wind force, but it is more suitable for dust control in open-pit coal and ore yards; dust control in building demolition, construction sites, and road dust, but For space restrictions, water restrictions, wind restrictions, the use of mist sprayer is not suitable
