    • A portable well treating fluid mixing system includes: a supply tank (12) having an inlet (24) receiving pneumatically conveyed dry treating material; a cyclone separator (28) having an inlet coupled to the supply tank and receiving dust laden air from the supply tank, and having a first outlet (30) venting clean air and having a second outlet (32) venting solids; a collection container (34) having a first inlet coupled to the cyclone separator second outlet and receiving solids from the cyclone separator and having an outlet; and, a pump (36) having an inlet (38) coupled to the collection container outlet and a pump outlet (40) coupled to the supply tank. In operation, the system continuously conveys dust from the collection container back into the supply tank to maintain the separator in proper operating condition and minimizes venting of dust during the transfer of material to the supply tank.
    • 便携式井处理流体混合系统包括:供给罐(12),其具有容纳气动输送的干燥处理材料的入口(24); 旋风分离器(28),其具有联接到所述供应罐的入口并且从所述供应罐接收载有灰尘的空气,并且具有排出清洁空气并具有排出固体的第二出口(32)的第一出口(30) 收集容器(34)具有连接到旋风分离器第二出口的第一入口并且接收来自旋风分离器的固体并具有出口; 以及具有联接到收集容器出口的入口(38)的泵(36)和联接到供应罐的泵出口(40)。 在操作中,系统连续地将收集容器中的灰尘返回到供应罐中,以将分离器保持在正确的操作状态,并最大限度地减少在将物料转移到供应罐中时排出灰尘。
