Description
Technical field
The device that the present invention relates to a kind of powder fluidization for delivery of powder state solid material, especially relates to a kind of powder fluidization air-breather.
Background technology
In industries such as metallurgy, chemical industry and cement, often need to carry powder state solid material at present. For the conveying of powder state solid material, if adopt the mode of fluidisation in advance, can significantly improve the solid-gas ratio that strength is carried, its prerequisite must have well behaved aeration equipment, ensures that powder can obtain good fluidized state. If aeration equipment selects improper or function is not good, can cause powder in poor fluidized state, cause powder in course of conveying, easily stockpile in duct bottom; Meeting blocking pipe when serious, causes strength to carry and cannot carry out. In addition,, for powder conveying apparatus, the selection of aeration equipment also affects investment, construction and the operating cost of package unit.
For preferably aeration equipment of performance, the disclosed patented technology of latest domestic is divided into two kinds at present. A kind of taper aeration equipment with inner chamber (ventilation cone) taking patent CN201493478U, CN201495203U, CN201864703U as representative, a kind of board-like aeration equipment (vent board) with fluidisation air chamber taking patent CN201424293Y as representative.
" the sintering metal multi-hole conical taking stainless steel, titanium, nickel or nickel alloy as material of the circular cone bench-type of hollow " of patent CN201493478U invention is fixed on the inside of taper conveyance conduit, the fluidizing gas passing into from outside, enter the inner chamber that cone and conical pipeline form, from cone surface escaping, fluidisation powder material. Although the sintering metal multi-hole conical industrial applications shown in this patent is more, complex structure, involves great expense, and is of limited application, and also easily damages, and is difficult for maintenance.
Patent CN201495203U and CN201864703U all announce a kind of aeration equipment of mechanical tapping formula, equipment described in its outward appearance and patent CN201493478U there is no significant difference, be the truncated cone of hollow, difference is to adopt the steel plate of perforate, instead of adopts sintering metal to make inner chamber wall. The main distinction between CN201495203U and CN201864703U is the size of micropore size and cone cone angle. The shortcomings such as these two patents all exist indifferent gas consumption large, and smooth and easy blanking and solid-gas ratio exist contradiction, and inner chamber easily enters powder, not quick detachable, and fluid effect is not good.
The aeration equipment that patent CN201424293Y addresses is mainly made up of micropore fluidized plate and housing. Micropore fluidized plate is arranged on the below of powder conveying tank, and housing, in the bottom of micropore fluidized plate, forms fluidisation air chamber with micropore fluidized plate. Fluidized gas enters powder conveying tank from fluidisation air chamber, and fluidisation powder is sent powder from the carrier pipe of upper end. The micropore fluidized plate of this patent adopts improved arcs of recesses, can reduce the loss of inertia fluidized gas, but also has complex structure, the shortcoming such as not quick detachable.
