What is the main equipment of the negative pressure metering chamber divided into?A negative pressure metering room is common local purification equipment, which is very much used in pharmaceutical, microbiological research, and some other places. The weighing room is mainly used for the weighing of pharmaceutical ratios, weighing and dispensing of dust and reagents, controlling the overflow and rise of dust and reagents, preventing the inhalation hazards of dust and reagents to human beings, avoiding the cross-pollution of dust and reagents, and protecting the external environment and the safety of the personnel in the room.The main equipment of the negative pressure metering room is assembled from the working area, return air box, fan box, outlet air box, and outer box, which can be used to control the starting and stopping work of the fan through the control panel, and also to adjust the wind speed required for the work. Please note that after the installation of the equipment, professionals can make adjustments and set the information of the equipment to work autonomously according to the intelligent operating system in it. This is very helpful in our daily work. As far as its structure is concerned, it is not complicated. That is, by providing vertical airflow in one direction, part of the clean air is circulated in the working area, and the rest is discharged to the nearby area, generating negative atmospheric pressure through the exchange of airflow to ensure a high degree of cleanliness in the working area and prevent cross-contamination. Negative pressure metering chambers not only prevent dust and reagents from overflowing but also prevent harmful gases from damaging our bodies, so the protective effect of negative pressure metering chambers can be said to be very great. The specific working principle is as follows: This equipment adopts the form of vertical unidirectional flow of airflow, the return air is first pre-filtered with an initial filter to deal with the large particles of dust particles in the airflow, after pre-treatment of the air, the air is filtered with an intermediate effect filter for the second time, which serves as a full protection of the high-efficiency filter. Under the pressure provided by the centrifugal fan, it is made to pass through the high-efficiency filter to meet the clean requirements. The clean airflow is transported into the air supply box body, 90% passes through the even flow air supply screen to form a uniform vertical airflow, and 10% passes through the air volume adjustment plate and is discharged out of the equipment. All airflow is effectively filtered, air supply and exhaust without residual dust, avoiding secondary pollution. Since the working area forms a stable unidirectional flow, the dust released in the area will be captured by the middle school effect filter with the airflow under the influence of the unidirectional airflow. The equipment comes with 10% exhaust, forming a negative pressure on the external environment, which ensures to a certain extent that the dust in the area will not spread to the outdoors and plays a role in protecting the external environment. |
