Description

Multifunctional negative pressure feeding equipment Technical Field The utility model relates to the field of negative pressure feeding equipment, in particular to multifunctional negative pressure feeding equipment. Background In the production process of the industries of medicine, food, chemical industry and the like, the feeding link of solid materials is an important component part of the production flow, and directly influences the production efficiency, the product quality and the operation environment. Taking the pharmaceutical industry as an example, in the production of pharmaceutical preparations, solid materials such as bulk drugs, auxiliary materials and the like are required to be put into mixing equipment, a reaction kettle or crushing equipment according to an accurate proportion, and the process has extremely high requirements on the tightness, the metering precision and the operation safety of the materials. The traditional feeding equipment adopts a gravity type or positive pressure pushing type structure. Gravity feeding is usually achieved by manual dumping or a simple hopper arrangement, from which the material falls directly into the underlying equipment. Gravity type feeding relies on manual control pouring speed, continuous and uniform feeding is difficult to realize, and the phenomenon of 'inattention and inattention' easily occurs. Meanwhile, in the process of feeding the particulate matters, the existing feeding equipment is easy to splash due to the falling process of gravity, and a large amount of dust can fly up from a gap to a workshop environment. Not only pollutes the production environment, but also can lead to the proportion unbalance of material components caused by dust loss, and influence the quality stability of the product. Disclosure of utility model The utility model aims to provide multifunctional negative pressure feeding equipment, and aims to solve the problem that the existing feeding equipment cannot stably and safely feed materials.
