Abstract
The utility model discloses a major-diameter bottom bin, wherein a steel sleeve (2) is sheathed outside a balance stock column (3) which is internally provided with an exhaust pipe (5); the exhaust pipe (5) is connected with a total exhaust pipe; the lower end of the balance stock column (3) is connected with a dust collection mouth of a pneumatic chute; the ground elevation of a bin bottom (1) is 2000mm; the length of the steel sleeve (2) is 1800mm; the diameter of the balance stock column (3) is 300mm, and the length of the balance stock column (3) is 2300mm; the balance stock column (3) is internally provided with a clapboard (6); the angle between the clapboard (6) and the vertical center line of the balance stock column (3) is 45 degrees; and the horizontal distance of the clapboard (6), over the center line, is 30mm. For the major-diameter bottom bin, the balance stock column of the pneumatic chute is hidden in the bottom bin, the height of the bin does not need to be increased, so that the normal convey of the pneumatic chute is ensured, increasing the height of the bin artificially is not needed, and the effects of being economical, practical and attractive are achieved.
Description
Technical field
The utility model relates to the feed bin that is used to store alumina powder in a kind of aluminium oxide and the aluminum electrolysis industry.
Background technology
Development along with modern aluminum industry, the continuous expansion of aluminium manufacturer's scale, in alumina producer, produce the amount of daily consumption aluminium oxide in alumina amount and the electrolytic aluminium factory daily all in continuous increase, the requirement of the bunker capacity that aluminium oxide is stored is also continuing to increase, in order to meet this requirement, under the present circumstances flat-bottom bin form that the enlarged diameter of feed bin is also adopted as far as possible the multiple spot blanking.Dispose pressure container or air-driven chute in the feed bin bottom and aluminium oxide is transported to next feed bin or uses a common mode that is the aluminium oxide conveying, the utility model is a kind of novel mode of balance stock column that disposes air-driven chute at the flat aluminium oxide feed bin of major diameter down.Smooth and easy according to traditional design for the conveying of air-driven chute, the design height of the balance stock column of chute generally is about 2.50 meters, add that the height at the bottom of the feed bin storehouse is approximately 4 meters after the setting height(from bottom) of air-driven chute, under same volume, just increased the height of feed bin like this, increased the consumption of material, increase the bearing capacity on feed bin basis, caused waste.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of major diameter flat-bottom bin is provided, and to overcome height at the bottom of the storehouse that prior art exists, increases material usage, increases the bearing capacity on feed bin basis, causes deficiencies such as waste.
The utility model is by the following technical solutions: outside the balance stock column steel sleeve is arranged, in the balance stock column freeing pipe is arranged, freeing pipe is connected with total air escape pipe; The lower end of balance stock column is connected with the mouth that gathers dust of air-driven chute; Ground elevation at the bottom of the storehouse is 2000 millimeters; The length of steel sleeve is 1800 millimeters.
The diameter of balance stock column is 300 millimeters, and length is 2300 millimeters.
Be provided with dividing plate in the balance stock column, the angle of dividing plate and balance stock column vertical center line is 45 °, and the horizontal throw that surpasses line of centers is 30 millimeters.
Upper spacer is 400 millimeters apart from the end face of balance stock column, and lower clapboard is 700 millimeters apart from the lower surface of balance stock column.
The bending angle that freeing pipe 5 stretches out outside the balance stock column is 45 °.
The utility model is that the balance stock column with air-driven chute is hidden in the flat feed bin, need not increase the height of feed bin, has both guaranteed the normal conveying of air-driven chute, and artificially too not high again feed bin height reaches effect economic, practical, attractive in appearance.

Fig. 2 is connection structure scheme drawings such as balance stock column of the present utility model and air-driven chute;
Fig. 3 is an integral structure scheme drawing of the present utility model.
The specific embodiment
Embodiment of the present utility model: it comprises balance stock column 3, blanking chute 4, and steel sleeve 2 is arranged outside balance stock column 3, and freeing pipe 5 is arranged in balance stock column 3, and freeing pipe 5 is connected with total air escape pipe; The lower end of balance stock column 3 is connected with the mouth that gathers dust of air-driven chute; 1 ground elevation is 2000 millimeters at the bottom of the storehouse; The length of steel sleeve 2 is 1800 millimeters, and diameter is 325 millimeters.
The diameter of balance stock column 3 is 300 millimeters, and length is 2300 millimeters.
Be provided with dividing plate 6 in balance stock column 3, the angle of itself and balance stock column 3 vertical center lines is 45 °, and the horizontal throw that surpasses line of centers is 30 millimeters.
Upper spacer is 400 millimeters apart from the end face of balance stock column 3, and lower clapboard is 700 millimeters apart from the lower surface of balance stock column 3.
The bending angle that freeing pipe 5 stretches out outside the balance stock column 3 is 45 °.
Imbedding a diameter according to air-driven chute balance stock column allocation position in advance when the major diameter flat-bottom bin is constructed is the steel sleeve 2 of 1.8m for 300mm length, with the freeing pipe optimal design of the version of conventional balanced stock column is novel balance stock column 3, the height that major diameter flat-bottom bin chute is installed passage only need be designed to 2m, when blanking chute 4 is installed, get final product being connected with the mouth that gathers dust of air-driven chute again in the balance stock column 3 feeding service sleeves.
