Abstract
The utility model relates to a pneumatic lifting device for sludge, particularly an anti-reflux pneumatic lifting device for sludge, which comprises a pneumatic lifting cavity body (3) and a compressed air pipe (4), wherein the longitudinal section of the pneumatic lifting cavity body (3) is trapezoidal, and an elbow of the compressed air pipe (4) positioned in the pneumatic lifting cavity body (3) is upward. The utility model is characterized in that the lower end of the pneumatic lifting cavity body (3) is fixedly connected with an anti-reflux cavity body (5), and the longitudinal section of the anti-reflux cavity body (5) presents an inverted trapezoidal shape; a spherical body (6) is arranged in the anti-reflux cavity body (5), and the diameter of the spherical body (6) is larger than the diameter of a sludge inlet (7) on the lower end of the anti-reflux cavity body (5). The utility model has the characteristic of anti-reflux performance, and simultaneously, the lifting height can be largely improved.
Description
Technical field
The utility model relates to a kind of sewage gas force lifting apparatus, is applicable to the lifting of mud and slurries, particularly is used for the lifting of the mud and the slurries of metallurgy industry ironmaking, steel-making, steel rolling and other field.
Background technique
Metallurgy industry is used mud lifting device at present, general adopt screw pump, slag stock pump, diaphragm pump, airlift etc. are arranged, the ironmaking of metallurgy industry, steel-making, steel rolling mud often adopt strength lifting device, adopt pressurized air to utilize the sewage gas force lifting apparatus to carry out the lifting of mud, this device utilizes pressure reduction pulsation the carrying out lifting of mud of pressurized air and mud both sides, this apparatus structure is simple, less investment, generally adopts at metallurgy industry.Traditional sludge airlift system comprises deposition tank 1, strength lifting device, settling tank 2, and its structural type as shown in Figure 1.The tradition strength lifting device, as shown in Figure 2, it is made of airlift cavity 3, compressed air hose 4, and the longitudinal cross-section of airlift cavity 3 is trapezoidal, the elbow that compressed air hose 4 is positioned at airlift cavity 3 makes progress, and this strength lifting device has following shortcoming:
1) owing to there is not anti-backflow device, when lifting height is higher, the refluence phenomenon usually taking place, cause pressurized air to flow backwards toward deposition tank one side, make deposition tank mud rout up from deposition tank, influence the water outlet effect of deposition tank, also makes mud can not get effective lifting.
2) owing to there is not check device, mud that is raised and gaseous mixture can not effectively obtain jacking, cause lifting height limited, and use is restricted.
Summary of the invention
At above-mentioned deficiency, the purpose of this utility model is to provide a kind of anti-back flow sewage gas force lifting apparatus of anti-back flow.
To achieve these goals, the technical solution of the utility model is: anti-back flow sewage gas force lifting apparatus, it comprises airlift cavity 3, compressed air hose 4, and the longitudinal cross-section of airlift cavity 3 is trapezoidal, and the elbow that compressed air hose 4 is positioned at airlift cavity 3 makes progress; It is characterized in that: the fixedly connected anti-back flow cavity 5 in the lower end of airlift cavity 3, the longitudinal cross-section of anti-back flow cavity 5 is trapezoidal for standing upside down, be provided with a spheroid 6 in the anti-back flow cavity 5, the diameter of spheroid 6 is greater than the diameter of the mud import 7 of anti-back flow cavity 5 lower ends.
The utility model adopts said structure, when spheroid 6 upper ends one side pressure during greater than spheroid 6 lower ends one side, spheroid is blocked mud import 7, when spheroid 6 upper ends one side pressure during less than spheroid 6 lower ends one side, spheroid 6 is backed down, and promotes mud by the pressure reduction pulsation that forms pressurized air and mud both sides.
The utility model preferably resolves and returns gas and backward flow problem, because the pulsating fluid of mud and air has had spheroid 6 jackings, lifting height is greatly improved simultaneously.
