Mortar conveying whirl depressurization system

The utility model discloses a mortar conveying whirl depressurization system belongs to mining machinery, aim at providing the depressurization system that can reduce the particulate slurry velocity of flow, guarantee thick liquids continuous uniform flow in the pipeline. It including be arranged in the buffer that leaks the hopper -shaped container, with the sand inlet pipe of this buffer intercommunication, buffer by spiral pipe (4) with sand inlet pipe (14) intercommunication, be located that this spiral pipe below and slope arrange at least two separate sieve (12) and constitute the adjacent slope opposite direction who separates sieve (12), the bottom of container (13) is fixed with blowing pipe (10) of taking baiting valve (11). The utility model discloses simple structure, convenient to use can not only subdue the mortar velocity of flow and kinetic energy, release pipeline delivery pressure, avoid pipeline rapid wear, but also can guarantee thick liquids in succession, even, full packages, stable tran
