Mine multi-particle-size dust preparation and intelligent spraying device

Abstract

The invention discloses a mine multi-particle-size dust preparation and intelligent spraying device. The device comprises a device body, and the device body is provided with a dust preparation cavity and an intelligent spraying cavity; a driving cavity, a transmission cavity, a vibration cavity, a vibration reduction cavity, a control cavity, a rotating cavity and a balance cavity are formed in the dust preparation cavity; a driving motor and a driving wheel are mounted in the driving cavity; and vibration screens, a funnel, an electromagnetic valve and a spraying gear are mounted in the vibration cavity. The use result of the device shows that the device is firm in structure and good in sealing performance, an electrical system is reasonable in layout and stable in control, screen body vibration is stable, motor power is strong, use is convenient, operability is strong, three-door design is achieved, so that maintenance is convenient, dust falls naturally during vibration, spill-proof performance is good, the storage space of the funnel is large, the spraying amount and spraying force are adjustable, accurate preparation and intelligent spraying of test dust with different particle sizes can be well achieved, and the device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the related technical field of mine dust monitoring and safety early warning, in particular to a preparation and intelligent spraying device for mine multi-particle size dust. Background technique [0002] With the popularization of automation equipment in mine mining, the unit output of coal is getting higher and higher, and the unit dust production is also increasing. Mine dust is usually divided into full dust and exhaled dust. All dust refers to all dust that can enter the respiratory tract. Exhaled dust (respirable dust) refers to the collected dust with an aerodynamic diameter of less than 7.07 μm and an aerodynamic diameter of 5 μm. The collection efficiency of the dust is 50%, and the exhaled dust can be deposited in the alveoli, which is very harmful to the human body. In the process of coal mining, there are multiple dust sources such as cutting coal walls by coal cutters, dust falling from moving racks, ground dust,...

AI Technical Summary

Problems solved by technology

In the process of coal mining, there are multiple dust sources such as cutting coal walls by coal cutters, dust falling from moving racks, ground dust, reloading dust, and dust carried by fresh air currents. , Erosion equipment, in severe cases can induce pneumoconiosis and there is a risk of spontaneous combustion, which has caused great safety hazards to coal mining and miners' lives and properties. The problem of dust prevention and control is very urgent
