Description

Technical Field

[0001] The utility model relates to the technical field of workshop air supply volume adjustment, in particular to a dynamic adjustment device for air supply volume in an environmental protection workshop. Background Art

[0002] Make-up air refers to the amount of air that needs to be added when adding fresh air or processing air flow. Its function is to ensure the indoor air quality while maintaining comfortable indoor temperature and humidity.

[0003] In an environmental protection workshop, a larger air circulation is usually required to improve the working environment in the workshop and reduce the air pollution in the working environment. At the same time, a larger amount of make-up air is also required to ensure the air quality. However, the make-up air volume and air circulation speed will not remain unchanged, and will change at any time according to the actual needs of the workshop. The make-up air and air circulation are performed by two different sets of equipment respectively. When adjustments are needed, the operator needs to adjust the two devices separately, and there are certain safety hazards during the operation process. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0007] The utility model provides a dynamic adjustment device for the air supply volume of an environmentally friendly workshop.

[0008] Furthermore, the air supply duct and the air supply duct are arranged parallel to each other, and spherical tubes are arranged inside the spherical placement cavities inside the two ducts.

[0009] Furthermore, the spherical tube is a tubular structure which is spherical as a whole and has openings arranged on the surface as imagined, and the opening diameter of the spherical tube is adapted to the air supply duct and the air supply duct.

[0010] Furthermore, the connecting rod is located between the two spherical placement cavities, and passes through the spherical placement cavities to be connected with the spherical tube.

[0011] Furthermore, there are two fans, which are respectively arranged at the two ends of the air supply duct and the air supply duct.
