Description

Technical Field

[0001] The invention relates to the technical field of pharmaceutical and chemical equipment, and in particular to an auxiliary device for adding high-risk liquid materials and a use method thereof. Background Art

[0002] In the production process of chemical products or medicines, liquid feeding is a common operation. To implement this feeding method in the factory, it is often necessary to open the barrel cover and add materials through a gun diaphragm pump. However, the existing feeding operation often has no strict protective measures and only uses nitrogen for inert protection, which will cause odor to escape. When the material is a high-risk liquid material, it will bring hidden dangers to the physical and mental health of the feeding personnel. In addition, due to the opening of the cover operation, it is also easy to introduce foreign matter from the external environment into the reaction system, resulting in cross contamination, which will also bring risks to product quality.

[0003] In the prior art, some protective covers for solid materials are disclosed, which can isolate dust and prevent dust from escaping when solid materials are added. However, this type of protective cover has a fixed structure and poor flexibility, and cannot be well adapted to the feeding gun head of liquid materials. Therefore, it is not suitable for the feeding operation of liquid high-risk liquid materials.

[0004] Therefore, there is an urgent need in the art for an auxiliary device for adding high-risk liquid materials, which is suitable for the addition operation of high-risk liquid materials and is compatible with the liquid feeding gun head. At the same time, it has a simple structure and is easy to operate, and can isolate the material system from the external environment to avoid the escape of materials, thereby ensuring product quality while protecting the physical and mental health of operators.
