Automatic spray dust suppression device for overrun of dust concentration

Abstract

The invention discloses an automatic spray dust suppression device for overrun of dust concentration, comprising a ground monitoring master station, a plurality of underground monitoring substations, a plurality of spray and sprinkling dust suppression host machines, a dust concentration sensor, a mine light control sensor and a mine explosive-proof electromagnetic valve, wherein the underground monitoring substations are connected with the ground monitoring master station; the spray and sprinkling dust suppression host machines are connected with the underground monitoring substations; the dust concentration sensor, mine light control sensor and mine explosive-proof electromagnetic valve are connected with the spray and sprinkling dust suppression host machines; the output end of the mine explosive-proof electromagnetic valve is connected with a spray component; and the spray component is composed of a plurality of high-pressure spray nozzles arranged in a spiral sector on a water pipe frame. The ground monitoring master station carries out hierarchical management on the underground monitoring substations and the spray and sprinkling dust suppression host machines and reports status words periodically, the normal work or abnormal work conditions of all underground devices are displayed on the ground monitoring master station through judgment of the status words, and the underground position of a device in abnormal condition is displayed by an underground position serial number. The automatic spray dust suppression device for overrun of dust concentration has the advantages of good spray effect, large coverage area, simultaneous control of automatic operation of a plurality of sprinkling points, good atomization effect, low water consumption and high sprinkling efficiency.

Description

technical field [0001] The invention relates to a dust suppression device, in particular to an automatic spray dust suppression device with dust concentration exceeding the limit. Background technique [0002] Water spray dust suppression devices such as light control, touch control, and sound control are commonly used in the spray dust suppression devices in coal mines. Due to the need for light control, manual or sound activation, low efficiency, small spray area, and water consumption are common. Large and inconvenient to use, and the opening time cannot be automatically changed with the change of dust concentration. [0003] In order to solve these problems, the Chinese patent (application number 201310681991.X) provides an automatic sprinkler and dust suppression device that includes a water inlet pipeline connected to a water source, and the water inlet pipeline is connected with several water spraying branches. The water spraying branch is provided with a number of w...

Problems solved by technology

The system disclosed in this patent seems to be comprehensive, but there are still problems in reality. Too many devices are installed and constructed underground, which is costly, and only one PLC is used for management. Although the PLC can self-check and report errors, any part of it is damaged or The connection line is damaged, and the maintenance staff can’t know it until they arrive at the scene. Moreover, the system has a small spray area, large water consumption, and inconvenient use
