Description

Para aminobenzoic acid weighing equipment Technical Field The utility model relates to the technical field of aminobenzoic acid processing equipment, in particular to para-aminobenzoic acid weighing equipment. Background In the production and experimental links of para aminobenzoic acid, accurate weighing of the powder is a key operation. The traditional weighing equipment has a plurality of technical problems when processing powdery para-aminobenzoic acid, on one hand, powder is extremely easily influenced by external air flow in the dumping process, such as air flow generated by indoor ventilation, personnel walking and the like, so that the powder is scattered, not only is material waste caused, but also the operating environment is possibly polluted, and the cleaning cost is increased, on the other hand, the powder is easy to accidentally leak out during dumping, is scattered on a weighing equipment body and peripheral areas, influences the weighing accuracy, and increases the cleaning burden of operators, so that the para-aminobenzoic acid weighing equipment is particularly provided for the problems. Disclosure of utility model In order to overcome the defects of the prior art, the embodiment of the utility model provides para-aminobenzoic acid weighing equipment, wherein a rotating handle and a rotationally connected guard plate are arranged at the top end of a weighing equipment body, when powder is poured, the guard plate can form a physical barrier to prevent disturbance of external air flow to the powder, and simultaneously prevent the powder from accidentally leaking out. In order to achieve the purpose, the p-aminobenzoic acid weighing device comprises a weighing device body, wherein an aminobenzoic acid powder containing container is placed at the top end of the weighing device body, a rotating handle is fixedly connected to the top end of the weighing device body, a guard plate is rotatably arranged outside the rotating handle and above the aminobenzoic acid powder containing container, the guard plates are symmetrically arranged on the weighing device body, and two groups of guard plates are rotatably connected to the rotating handle. In a preferred embodiment, the guard plates are arranged in a semicircular shape, the caliber of the ring formed by combining the two groups of guard plates corresponds to the caliber of the aminobenzoic acid powder container, one group of guard plates is fixedly connected with a magnetic attraction block, the other guard plate is provided with a magnetic attraction groove at one end, and the magnetic attraction groove is in magnetic connection with the magnetic attraction block. In a preferred embodiment, a moving groove is formed in the guard plate, a pushing rod is movably arranged in the moving groove, a spring is arranged in the moving groove, and the pushing rod penetrates through the moving groove and is fixedly connected with a scraping plate.
