| titleOfInvention | Water injection and differential pressure water supply system and control method for wet dust removal system of down-the-hole rock drilling equipment |
| abstract | The invention provides a water injection and pressure difference water supply system and a control method of a wet-type dust-removing device for down-the-hole rock drilling. It is connected with the main working pipeline of the drilling rig; the position where the air intake pipeline and the water delivery pipeline are matched with the main working pipeline of the drilling rig is provided with a pressure difference generating device for generating pressure difference; the top side of the pressure vessel is installed with a device for rapid water injection and emptied water filling and draining device. This device can be used in the drilling rig wet dust removal device to form a pressure difference inside the pressure vessel, and then according to the fluid inside the main pipe, a pressure difference can be generated inside the pressure vessel, and then the water inside is automatically injected into the inside of the main pipe of the drilling rig, without the need for Additional pressurization equipment is added; and rapid water injection of closed pressure vessels can be achieved by adopting a rapid water injection structure. |
