Industrial dust mop vacuum cleaner

Abstract

An improved, electric motor driven dust mop vacuum cleaner is provided that employs rotating brushes, high vacuum, and an efficient air filtration system. The rotating brushes housed in a closely fitting tub remove the dust and dirt from the dust mops and by means of impellers in the vacuum motor chamber. The dust and dirt are then passed on to the air filtration system. The air filtration system consisting of an intake port, removable particulate trapping tray, and exhaust port filters, remove the particulates from the air before returning it to the environment. The particulate trapping tray located at the base of the unit and behind a hinged door, contains an effective particulate trapping liquid. The entire apparatus is movable by means of casters mounted on the base of the unit.

I claim:  
     
         1 . An improved industrial dust mop vacuum cleaning apparatus incorporating a centrifugal high vacuum fan assembly comprised of fan housing  31 , impeller  32 , and electric motor  33 , connected to a close fitting tub  29  in which the cleaning brush  10  rotates and covered by close fitting brush cover  7  which provide high vacuum to extract dust and debris from dust mops cleaned therewith.  
     
     
         2 . An improved industrial dust mop vacuum cleaning apparatus incorporating an air filtration system comprised of air seal  35 , intake port  20 , dust collector box  16  containing dust-collecting liquid  18  for dust particle entrapment, exhaust port  21 , screen  13 , and air filter  19  for the final removal of dust and debris from the air used to clean the dust mop prior to returning that air into the environment. This configuration assures that dust and debris do not bypass the air filtration system.  
     
     
         3 . An improved industrial dust mop vacuum cleaning apparatus incorporating a removable dust collector box  16  that contains dust-collecting liquid  18  to assure that dust and debris cannot bypass the air filtration system but are completely collected in the air filtration system.  
     
     
         4 . An improved industrial dust mop vacuum cleaning apparatus incorporating a single clockwise rotating brush  10  whose axial length is greater than an industrial dust mop and is covered by adjustable brush guard  9  and brush cover  7 , and incorporating brush guide  8 , all in a configuration that provides superior dust mop cleaning by uniformly brushing all the strands of the dust mop without damage to the dust mop while preventing entrapment of the dust mop or the hands of the operator in the improved industrial dust mop vacuum cleaning apparatus.  
     
     
         5 . An improved industrial dust mop vacuum cleaning apparatus incorporating a hinged door  6  and removable cover  14  to provide easy access to the air filter  19 , dust collector box  16 , electric motors  23  and  32 , and V belt  26  which require access for periodic maintenance.
