Technical Field

[0001] The utility model relates to the technical field of dust removal and ventilation, and specifically, to a dust removal and ventilation device. Background Art

[0002] In the HVAC engineering, a dust removal and ventilation device refers to equipment used to remove dust, impurities, and pollutants from the air. It is usually used in industrial, commercial, or residential buildings to improve indoor air quality and keep the air clean. The dust removal and ventilation device can include various equipment such as filters, dust collectors, air purifiers, etc., which are used to remove solid particles, bacteria, viruses, harmful gases, and odors in the air. In commercial and residential buildings, the dust removal and ventilation device helps to provide a healthy and comfortable indoor environment and reduce the impact of allergens and harmful substances on the health of residents.

[0003] In the dust removal and ventilation device in the HVAC engineering, a set of devices usually needs to be responsible for the ventilation and dust removal tasks in a relatively large area. Therefore, when the pipeline is damaged and needs to be repaired, or during regular pipeline maintenance, it is necessary to stop working first, stop the ventilation and dust removal of the entire pipeline, and then carry out the repair or maintenance. If the repair or maintenance time is too long, it will lead to a decline in indoor air quality, especially in an environment that requires dust removal, it will cause dust or pollutants to accumulate, which will have an impact on the health of personnel.

A wind baffle is arranged inside the connecting pipeline, and the wind baffle is indirectly driven by a servo motor to move and control the threaded rod. When one of the pipelines in branch pipeline one and branch pipeline two needs to be repaired or maintained, the wind baffle can be moved to close one set of pipelines, so that it is not necessary to stop the entire ventilation and dust removal system. By setting two sets of working pipelines, it is possible to avoid the entire system from stopping working due to too long repair time, thereby improving its use stability.
