The invention relates to the technical field of silica conveying and discloses conveying equipment used for fumed silica production. The equipment comprises a first through pipe, a second through pipe, a third through pipe, a fourth through pipe and a driving pump. The driving pump comprises a shell, a first diaphragm, a second diaphragm, a first laminated film plate, a second laminated film plate, a connecting rod and a middle body. The equipment is simple in overall structure, the first diaphragm and the second diaphragm are connected to the two ends of the connecting rod, accordingly, smallvacuums are produced in the third through pipe and the fourth through pipe in sequence, therefore, pressure in the first through pipe, the second through pipe, the third through pipe and the fourth through pipe is stable, the silica production quality is improved, meanwhile, not much air enters a conveying system, HCL is absorbed by a tail gas recovery system more easily, accordingly, a small vacuum sucks silica in and presses the silica out of the equipment, a silica conveying effect is achieved, moreover, the amount of gas required for the driving pump is small, the gas amount for the wholeproduction system is decreased, and therefore, the power consumption of the system is reduced.
Description
technical field [0001] The invention relates to the technical field of fumed white carbon black transportation, in particular to a conveying device for the production of fumed white carbon black. Background technique [0002] At present, in the production process of domestic fumed silica, Venturi jet mixers are used to transport silica. A large amount of gas is required in the transportation process, and the fluctuation of the injected gas volume will cause the system pressure to be unstable, especially the instability of the deacidification furnace material level. If the gas delivery volume is reduced, the gas injection velocity during the Venturi delivery process will decrease, which will cause system blockage. If the gas delivery volume is increased, the gas injection velocity of the Venturi mixer will increase, and the residence time of white carbon black in the deacidification furnace may be too short. , the material level of silica in the deacidification furnace is di...
