Embodiment 1

[0036]Prepare the isolator of the present invention, which is composed of a box body, an exhaust system, an air intake system and a control system; the exhaust system adopts a high-efficiency filter, and a pneumatic switch valve is arranged on the pipeline, which is automatically closed when the equipment leaks. When the equipment is shut down, the exhaust valve is closed to avoid contact between the box and the outside world; the airflow mode of the air intake system is a turbulent flow mode, which is divided into air intake and nitrogen intake, which can be switched freely; the intake of the air intake system The air port is equipped with a manual butterfly valve to adjust the number of air changes of the equipment; the nitrogen intake system is divided into two intakes, and the intake flow is adjusted and monitored by the flow meter. The nitrogen intake is weighed when the intake is single. Mode, at this time, the nitrogen gas flow enters the box smoothly, without affecting ...

Embodiment 2

[0039] The isolator is used to adjust the oxygen concentration of the isolator cabin. The equipment includes two intake modes: nitrogen intake mode, which is suitable for materials sensitive to oxygen concentration; air intake mode, which is suitable for ordinary materials. Nitrogen gas intake mode: After starting the work, after the oxygen content meter detects that the oxygen content is higher than the set value, the nitrogen control valves 1, 2, exhaust valve 4, and fan 6 are opened, and the air intake valve 3 is closed, and the air in the box is started. After the detection value of the oxygen content meter 7 is lower than the set value, the nitrogen control valve 1 is closed, the air intake valve 3 is closed, and the nitrogen control valve 2, exhaust valve 4, and fan 6 are kept running, and the equipment enters In the slow air flow replacement mode, weighing and sub-packaging can be carried out at this time. During the whole process, the differential pressure transmitter 8...

Abstract

The invention relates to a novel isolator capable of adjusting concentration of oxygen in a cabin. The isolator comprises a box body, an air exhaust system, an air intake system and a control system. The air exhaust system adopts an efficient filter; a pipeline is provided with a pneumatic on-off valve, and when leakage detection is performed on equipment, the pneumatic on-off valve is automatically closed; when the equipment is in a shutdown state, an air exhaust valve is closed, so that the box body can be prevented from contacting the outside world; the air flow mode of the air intake system is a turbulent flow mode and is divided into an air intake mode and a nitrogen intake mode which can be switched freely; an air intake port of the air intake system is provided with an manual butterfly valve used for adjusting the air exchange times of the equipment; a nitrogen intake system is divided into two air-intake paths; air-intake flow can be adjusted and monitored through a flowmeter; when nitrogen intake is in a single-path air-intake state, a weighing mode is realized, nitrogen flow enters the box body slowly and smoothly, and weighing is not influenced; and when nitrogen intake is in a double-path air-intake state, a replacement mode is realized, and oxygen content quickly drops to 5% and below. The isolator has an oxygen concentration adjustment function in the turbulent flow mode, and is suitable for being applied to the production of highly-toxic or highly-active products requiring lower oxygen concentration.

Description

technical field [0001] The invention belongs to the field of isolator instruments, and relates to an isolator, especially a novel isolator which can adjust the oxygen concentration of the isolator cabin. production needs. Background technique [0002] Recently, relevant studies have found that the onset age of the population is earlier, and the types of diseases and their occurrence and development are diversified. Therefore, more and more antineoplastic drugs, hormone drugs, antipsychotic drugs, and biotechnology drugs are continuously developed and gradually put into practice. in production. Therefore, the matching isolators are also widely put into actual production. Since highly active drugs such as antineoplastic drugs, hormone drugs, and biotechnology drugs have serious hazards in the production and operation of drugs, they have been identified as high-risk production operations by domestic and foreign experts. In view of this, it is necessary to equip isolators in ...
