Description

TECHNICAL FIELD

[0001] The utility model relates to a shunt device for cyclone separator. BACKGROUND

[0002] The cyclone separator is a commonly used gas-solid separation equipment, which is widely used in air purification, atmospheric sampling, industrial dust removal and other fields. The cyclone separator for air pollen online observation equipment is disclosed in the utility model patent with the application number ZL202122600584.4, which has six air inlets and one air outlet. When the cyclone separator is applied to the patent with the application number ZL202122600547.3 and the name of a kind of air pollen online observation equipment with high precision, the air inlet and the air outlet need to be connected through different pipelines to realize, which will occupy more space and consumables. Moreover, the air inlet and the air outlet are often designed separately in traditional equipment, which makes the air path complex and the air path components many, and interference is easy to occur. Therefore, how to design a system that can realize air inlet and air outlet at the same time in the same equipment is crucial to improve the comprehensive performance and application range of the equipment.

[0003] In addition, during the atmospheric sampling process of the pollen equipment, the distribution and stability of aerosol particles in the atmosphere in the airflow directly affect the reliability of particle collection. Due to the different design methods of the six air inlet pipelines of the cyclone separator (such as different lengths, different bending angles, etc.), the inhaled air of the six air inlets will have time and space differences, which will cause the collected particles of the pollen equipment to have systematic deviation. The consistency of the inhaled air is closely related to the design of the air inlet and the air outlet of the pollen equipment. If the airflow cannot be effectively and uniformly distributed before entering the cyclone separator, or an unstable cyclone is formed in the cyclone separator, it will affect the authenticity of the final measurement results. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a shunt device for cyclone separator, which can realize simultaneous air inlet and air outlet of the equipment and ensure balanced distribution of the airflow.

Furthermore, by setting the top air inlet at the top center of the main body of the flow-dividing device, and evenly distributing six bottom air outlets around the bottom of the main body of the flow-dividing device, a balanced distribution of multi-channel airflow is achieved, effectively optimizing the airflow path.

It is suitable for use in portable air sampling and small laboratory equipment. This miniaturized design is particularly suitable for on-site sampling and mobile testing, thus broadening the application range of the device. Attached Figure Description
