Problems solved by technology

Mine dust has hazards such as reducing the service life and precision of equipment, reducing the visibility of the production site, and causing occupational diseases (pneumoconiosis) for long-term dust-exposed personnel. Coal dust also has the danger of explosion
Spray dust reduction is the most common way in the mine production process, but often due to the instability of the spray water pressure, the water spray volume of the nozzle is suddenly large and small, resulting in poor spray effect, and the fixed nozzle atomization angle of the mine is limited. There are problems such as dead angle areas and poor atomization effect of pure water spray

Abstract

The invention discloses a steady flow spraying device. A water inlet pipe and a gas inlet pipe are arranged on a base. An atomizing chamber is arranged at the front end of the base. The gas inlet pipe communicates with the atomizing chamber. A plurality of water inlets are formed in the positions, corresponding to the atomizing chamber, of the water inlet pipe and form a water inlet zone. An adjusting structure is arranged in the water inlet zone and used for keeping the flow entering the atomizing chamber from the water inlet pipe unchanged. When water flow enters the atomizing chamber through the water inlets of the water inlet pipe, water drops are broken through blowing and dispersed into smaller fog drops through high-pressure gas, and the atomizing effect is improved; meanwhile, when the water pressure in the water inlet pipe is low, the adjusting mechanism enables the multiple water inlets to communicate with the atomizing chamber, the water flow area is increased, and the flow is unchanged under the condition that the water speed is low; and when the water pressure in the water inlet pipe is high, the adjusting mechanism blocks the corresponding water inlets and enables the corresponding water inlets to communicate with the atomizing chamber, the water flow outlet area is decreased, and the flow is unchanged under the condition that the water speed is high, so that the stability of nozzle spraying is ensured.

Description

technical field [0001] The invention relates to the field of spray dust reduction, in particular to a steady flow spray device. Background technique [0002] In the process of mine production, a large amount of dust is produced, especially the high-yield, high-efficiency and highly mechanized mining process, which keeps the dust in the underground air at a high concentration. Mine dust has hazards such as reducing the service life and precision of equipment, reducing the visibility of the production site, and causing occupational diseases (pneumoconiosis) for long-term dust-exposed personnel. Coal dust also has the danger of explosion. Spray dust reduction is the most common way in the mine production process, but often due to the instability of the spray water pressure, the water spray volume of the nozzle is suddenly large and small, resulting in poor spray effect, and the fixed nozzle atomization angle of the mine is limited. There are problems such as dead angle areas a...
