Device for handling of toner powder

Abstract

A device for handling volatile particles, during emptying of vessels containing the particles, includes an opening for emptying the particles, a collection vessel for emptied particles, placed mainly vertically below the opening in order to catch particles that fall down by gravitation, an airflow creating element, at least one filter, whereby the airflow creating element is capable of creating an airflow through the opening towards the collection vessel, as well as an airflow guiding element arranged such that the direction of the airflow is altered towards the filter in order to catch particles that are brought with the airflow.

1 . Device for handling volatile particles, during emptying of vessels containing said particles, comprising:
 an opening in the device for emptying of particles,   a collection vessel for emptied particles, placed mainly vertically below the opening in order to catch particles that fall down by gravitation,   an airflow creating means,   at least one filter, whereby the airflow creating means is capable of create an airflow through the opening towards the said collection vessel, as well as   an airflow guiding means arranged such that the direction of the airflow is altered towards the filter in order to catch particles that are brought with the airflow.   
     
     
         2 . Device according to  claim 1 , wherein said filter is placed in the vicinity of said opening, and said air flow guiding means is capable of changing the direction of the air flow such that it passes up through said opening. 
     
     
         3 . Device according to  claim 2 , wherein said air flow guiding means comprises a plate placed in said opening in a mainly vertical position, whereby said opening is divided into two part-openings where the air flow is going down in one part-opening and the other in the second part-opening. 
     
     
         4 . Device according to  claim 3 , wherein said air flow guiding means further comprises a pipe that extends between the opening and the collection vessel. 
     
     
         5 . Device according to  claim 3 , wherein said filter is arranged with a certain angle over the second part-opening. 
     
     
         6 . Device according to  claim 1 , wherein the filter also comprises an absolute filter. 
     
     
         7 . Device according to  claim 1 , wherein the air flow creating means suitably is a fan. 
     
     
         8 . Device according to  claim 4 , wherein said filter is arranged with a certain angle over the second part-opening. 
     
     
         9 . Device according to  claim 2 , wherein the filter also comprises an absolute filter. 
     
     
         10 . Device according to  claim 2 , wherein the air flow creating means suitably is a fan.
