Thesis project at R&D Dusty and Slurry, Construction: Dust extractor cyclone auto dump

Are you a student within mechanical engineering and search for a thesis project? Husqvarna Group and our Construction division are searching for students to do their thesis work about "Dust extractor cyclone auto dump" at R&D Dust and Slurry.

Thesis project: Dust extractor cyclone auto dump
In order to increase uninterrupted runtime in our dust extractor systems. A way of automatically getting material out of the dust cyclones, without interrupting suction is required. Today’s extractors generally need to block off or drastically lower air flow in order to completely empty the cyclone into a bag system.


  • Investigate if it is possible to design a robust auto dump function that can be manually & automatically controlled added to our line of dust extractors. 
  • Develop and test a prototype using Husqvarnas in house and external prototype suppliers.

The thesis include:

  • Investigate different options for how to empty out a dust extractor cyclone without losing airflow in the dust extraction system.
  • Decide which option is viable. Design & develop a prototype that can be engaged/disengaged manually and with a potential to be managed automatically. With simplicity and robustness in mind.

Reporting will be through regular meetings and written documentation in the form of a "Husqvarna design guideline" as well as the wishes of the university.

Proper area of education: Mechanical Engineering
