On-site automatic preparation system for mixed injection slurry

Abstract

The invention provides an on-site automatic preparation system for mixed injection slurry, and relates to the technical field of mine curtain slurry injection or water conservancy anti-seepage slurry injection. External hardware equipment comprises weighing and adding equipment, slurry stirring equipment and slurry conveying equipment, wherein the slurry stirring equipment structurally comprises a stirring tank, and a pumping and jet flow water pump is connected with an inner cavity of the stirring tank through a slurry inlet pipe and a slurry outlet pipe. The external hardware equipment is in communication connection with central control equipment, power distribution control enables signals to be transmitted accurately and achieves accurate control over the equipment, and a single worker can independently finish continuous preparation of the slurry. A computer of the central automatic control equipment sends control instruction signals to the external hardware equipment according to the needed preparation proportion of the slurry and a corresponding slurry storage device. The on-site automatic preparation system for the mixed injection slurry achieves the purpose that the slurry is used once being prepared, avoids waste of the slurry, is easy and convenient to operate, can be operated only by one worker, saves manpower and material resources, guarantees the quality of the slurry, and largely improves economic and social benefits.

Description

technical field

[0001] The invention relates to the technical field of mine curtain grouting or water conservancy anti-seepage grouting. Background technique

[0002] At present, in order to save the cost of grouting, mixed grout is generally used for mine curtain grouting or water conservancy anti-seepage grouting. The preparation of the slurry is still in a relatively primitive semi-artificial state, that is, it is prepared at the wellhead, and the slurry materials and admixtures other than the base slurry are added manually according to the required slurry ratio. This method greatly increases the use of personnel, and it is necessary to set up multiple larger sites on site for equipment placement, and the capacity for secondary mixing is limited, and only 1-2 drill holes can be supplied for grouting. Artificially added materials cannot accurately and stably supply the same proportion of grout, thereby affecting the spread of the grout, thereby affecting the grouting eff...
