Novel down hole drilling rig dust exhaust rubber-coupled molding curing dust suppression system

Abstract

The invention discloses a novel down hole drilling rig dust exhaust rubber-coupled molding curing dust suppression system. The novel down hole drilling rig dust exhaust rubber-coupled molding curing dust suppression system comprises a dust catching cover, a settling chamber, a filter core dust collector and a dust removal fan, and a dust collecting box is arranged on the filter core dust collector; a backblow buffer filter chamber is arranged on the side wall of the dust collecting box; the novel down hole drilling rig dust exhaust rubber-coupled molding curing dust suppression system furthercomprises a forced mixing rubber-coupled dust exhaust mechanism and an intelligent control dust-fixing mechanism; the forced mixing rubber-coupled dust exhaust mechanism and the intelligent control dust-fixing mechanism are all connected with a controller; a mixing rubber-coupled moulding system is designed on the tail part of a fine dust collector dust exhaust system, the separated fine dust is subjected to wetting, stirring and cross-linking to form granular to be discharged, and an effectively eliminate drilling rig operates in the process of backblowing and regeneration of a filter core for dust leakage; and meanwhile, an electronic control automatic quantitative dust suppressant spraying device is designed on the upper part of a dust exhaust stack and on the upper part of a cyclone slag collecting and discharging cover, the dust discharge stack is subjected to surface layer gluing connection curing treatment to control the possibility of dust and slag discharge being temporarily stacked in stope under the influence of natural wind before blasting, and a secondary dust source is eliminated.

Description

technical field [0001] The invention relates to a dust suppression device, in particular to a novel dust suppression system for down-the-hole drilling rigs which are dust-expelled and cemented. Background technique [0002] At present, the dust removal method of the dust removal system of the down-the-hole drilling rig used in open pit mines mostly adopts a dry filter element and a gravity natural fall dust removal system. The existing dry dust removal system is mainly composed of a dust collection cover 1, a settling chamber 3, a filter element dust collector 4, and a dust removal fan 5, such as figure 1 shown. [0003] When the drilling rig drills a hole on the rock surface 8, the compressed air of the air compressor is blown into the borehole by the drill rod 2, and the dust residue in the hole is blown out. The dust removal fan 5 is started, and a negative pressure is formed in the dust collection cover 1 of the dust removal system, and the dust residue enters the dus...

Problems solved by technology

However, the filter element is bound to be easily blocked by fine dust during the dust and air separation process, which increases the filter resistance of the filter element and reduces or even eliminates the dust removal efficiency.

At this time, back blowing must be carried out to clean the filter element to restore the filtering function. This process needs to release the dust suction pressure. During the process, there is intermittent dust in the air, which cannot meet the environmental protection requirements.

[0007] 2. At the same time, the dust collection box discharges dust to the ground. At the same time, due to the blowing action of the natural wind in dry weather on the discharged dust, it is inevitable that dust will pollute the air environment near the drilling rig, causing pollution hazards to equipment and air.

At present, the dust and slag discharge can only be temporarily piled in the open air, waiting to be mixed into the explosion pile to be fused as raw materials during blasting or waiting to be processed here
