Abstract
The utility model discloses a rotational air current type concrete dry-delivery wet shotcreting machine, which is formed by a spiral feeder, a spiral air current generator, an air and material mixer,a delivery pipeline and a decompressed atomization wet condenser, wherein the spiral air current generator is used to convert the compressed air in a mine pipeline into rotational air current which isused as a power source, and the air and material mixer is used to fully mix concrete with air to form gas-solid two-phase even mixtures; and the decompressed atomization wet condenser is used to enable dry concrete powder to form sticky mixtures after being filled with water and being atomized at the end of the pipeline. The utility model provides a mechanized device for the concrete gob-side entry retaining filling.
Description
Technical field
The utility model relates to concrete forming conveying technology field under the coal mine.
Background technology
In the underground mining of colliery, require to keep between two work planes 10 meters protection coal column, then 1,000,000 tons stope must leave 100,000 tons of protection coal columns, and these coals can not be exploited the serious waste that causes coal resources.The mine that has has at present adopted gob side entry retaining filling concrete that coal column is cemented out, but needs artificial concrete spice during concrete filling, and artificial transportation uses vibrating head to stir operations such as wet feed.Labor strength is big, and the concrete setting curring time is long, intensity is little, the roof timbering weak effect.Therefore be sought after a kind of concrete gob side entry retaining stowage unit of mechanization
The utility model content
For addressing the above problem, the utility model provides a kind of rotary air flow type concrete dry-conveying and wet-concreting machine.
Technical scheme is: it is made up of feed screw, spiral air flow generator, wind feed mixer, transfer pipeline and vacuum atomization condenser, wherein:
The structure of spiral air flow generator is with the end sealing of a segment pipe housing, at even oblique connection 2-4 breeches pipe of tube wall week side, to be connected with the down-hole high pressure airduct by a breeches pipe; The other end of pipeline shell is as air outlet; Breeches pipe outlet axially and pipeline axial be α=30-40 ° angle, and tangent with pipeline shell section circumference;
The structure of wind feed mixer is: an end of a segment pipe housing as air intake, and is connected with the air outlet of spiral air flow generator; Pipeline shell tube wall end face is provided with charging aperture, is tightly connected by charging aperture and feed screw discharging opening; The other end of pipeline shell is set to tubaeform discharging opening, connects transfer pipeline by tubaeform discharging opening, and the transfer pipeline outlet is gone up and connected vacuum atomization condenser;
