Passive spiral homogenization and dust suppression device and technology for grouting materials

Abstract

The invention discloses a novel device and process for passive spiral homogenization and dustfall of injecting paste materials. According to the device and the process, intelligent flow control valves are used for controlling the ratio of the injecting paste materials on line; the dead weight of the injecting paste materials and the wind power are used as a power source for homogenization of the injecting paste materials; after the injecting paste materials are uniformly mixed through a passive spiral homogenizer, the uniformly mixed injecting paste material is conveyed into a stirring pool through wind power, dust particles in dusty gas are comprehensively separated through a high cyclone separator and an electrostatic re-separating device, the clean air separated from the dust particles is discharged into atmosphere through an air outlet, the separated dust is collected in a storage area at the bottom of the high cyclone separator, through the adjusting of a closed controller, the dust is finally discharged into the stirring pool, water of which amount meets the design requirement is fed into the stirring pool, and the mixture is fully stirred and then is pumped into a project which needs the injecting paste materials. According to the device and the process, the ratio of the injecting paste materials is controlled on line, the dead weight of the injecting paste materials and the wind power are used to replace a conventional spiral stirring homogenization manner, meanwhile, the separating devices (namely, the high cyclone separator and the electrostatic re-separating device) are used to separate dusty gas, and the separated dust is discharged into the stirring pool, so that the high-accuracy material ratio is realized.

Description

technical field [0001] The invention relates to the technical field of rock soil and mine engineering grouting material homogenization and dust reduction facilities, in particular to a passive spiral homogenization and separator dust reduction device and process. Background technique [0002] In the process of rock and soil, tunnel, water conservancy, and mining, grouting technology is an effective technical means that takes into account both the reinforcement of surrounding rock and the prevention and control of water. Grouting technology is to use hydraulic pressure, air pressure, electrochemical principles and other methods to inject grout into the formation through grouting drilling or a grouting device placed in it. The grout is filled, infiltrated, compacted and split. After driving away the moisture and air in the rock and soil particles or in the rock fissures, it occupies its spatial position. After a certain period of manual control, the grout will cement the origi...
