Automatic large -traffic fluidic device

The utility model relates to an oil field technical field, in particular to automatic large -traffic fluidic device. The device includes outer taper pipe, stock solution chamber, dispersion room and advances the tube cell, advances the outer taper pipe of tube cell intercommunication, be equipped with the feed liquor pipe on the stock solution chamber, liquid is from the feed liquor duct flow through stock solution chamber, outer taper pipe and dispersion room, entering tube cell one side and connecting variable feeding mechanism, variable feeding mechanism includes servo motor and speed reducer, and servo motor drive speed reducer drives the motion of dispersion room, the formation negative pressure was taken the intraductal powder of outer cone out of and is dissolved with the liquid intensive mixing when high -speed flowing liquid flowed through outer taper pipe, connecting the variable flow feeder on one side of the feed liquor pipe and constructing, variable feeding mechanism and variable flow feeder structure come the manual work through the electronic display module and set for linkage and ratio adjustment that the proportion that supplies liquid, confession powder realized confession liquid, supplied the powder. The utility model provides an automatic large -traffic fluidic device, exquisite, the simple and practical of the device design can mix liquid and particulate matter effectively accurately according to the ratio.
