Novel device and process for passive spiral homogenization and dustfall of injecting paste 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 homogenization and dust reduction facilities for grouting materials in geotechnical and mining engineering, in particular to a passive spiral homogenization and separator dust reduction device and process. Background technique [0002] In the process of rock soil, tunnel, water conservancy, and mine mining, grouting technology is an effective technical means that takes into account the effects of surrounding rock reinforcement and water prevention. Grouting technology is to use hydraulic, pneumatic, electrochemical principles and other methods to inject grout into the formation through grouting boreholes or grouting devices placed in them. The grout is filled, penetrated, compacted, and split. After driving away the water and air in the rock and soil particles or in the rock fissures, they occupy their spatial positions. After a certain time of manual control, the grout cements the original loose soil or fissu...
