Medical intermediate grinding equipment

Abstract

The invention discloses medical intermediate grinding equipment which includes a grinding device, a circulating screening device, a collection bin and two frame bodies. The grinding device includes agrinding bin and a grinding mechanism, a feed inlet and a discharge port are formed in the upper side and the lower side of the grinding bin correspondingly; and the circulating screening device includes a screening bin, a screen plate and a circulation mechanism capable of driving the screening bin to move from the lower part of the grinding bin to the upper part of the grinding bin. The circulation mechanism can enable the screening bin to move from the lower part the grinding bin to the upper part of the grinding bin, so that scraps that do not meet the requirements of a coarse grain levelare poured into the grinding bin again, and the required grinding effect is achieved; manual operation by the operator is not required, the labor amount of the operator is reduced; and a second cylinder that can push the screening bin is arranged, so that the scraps that meet the requirements in one crushing can quickly pass through the screen plate, the scraps that meet the requirements are prevented from being crushed again, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the field of pharmaceutical intermediate production equipment, in particular to a grinding equipment for pharmaceutical intermediates. Background technique [0002] The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of pharmaceutical synthesis; such chemical products do not require a pharmaceutical production license, and can be produced in ordinary chemical factories, as long as they meet certain requirements. grade, which can be used for the synthesis of medicines; [0003] Grinding equipment is used for grinding some pharmaceutical raw materials. The patent application number 201811359530.X discloses an automatic grinding device for pharmaceutical intermediates, including a mobile support frame, a shearing device, a feeding hopper, a grinding chamber, Grinding rollers, collection boxes and control boxes, a workbench is set on the upper end of the mobi...
