Quantitative filling device for preparing o-nitrobenzoic acid and production process thereof

Abstract

The invention relates to the technical field of quantitative filling, and discloses a quantitative filling device for preparing o-nitrobenzoic acid and a production process thereof. The quantitative filling device comprises a support, a movable shaft is movably connected to one side of the support, a material box is arranged at the outer side of the movable shaft, and fan-shaped holes are formed in the middle of the material box at equal angles; and the material box is fixedly connected with a flexible sheet through the fan-shaped holes. When materials are filled into a package, gas mixed with the materials in the package is introduced into the position between the material box and a recycling box to be stacked and recycled, and the cross section of a fixing plate is arranged, so that the output amount of the gas mixed with the materials is reduced, the mixed gas is stored between the material box and the recycling box, and the materials are prevented from being sprayed outwards and wasted; and meanwhile, through the shape arrangement of the material box and the recycling box, the materials in the mixed gas can be quickly accumulated between the material box and the recycling box and can be accumulated at the outer side of a movable air bag for next filling, and the filling cost of the materials is reduced.

Description

technical field [0001] The invention relates to the technical field of quantitative filling, in particular to a quantitative filling device for preparing o-nitrobenzoic acid and a production process thereof. Background technique [0002] O-nitrobenzoic acid is usually filled and stored in ziplock bags, aluminum foil bags, cardboard barrels and plastic barrels during filling, among which cardboard barrels and plastic barrels with stable bottle mouth size and easy filling are most commonly used. During the filling process, the filling machine is used for filling. During the operation of the filling machine, the filling machine is composed of multiple parts, among which the filling motor controls the filling of the material, and the stirring motor stirs the material through the agitator. , the material box is filled with the material to be filled. [0003] During the canning process of the filling machine, the packaging is placed below the bottom of the material box, and the b...
