Abstract

The invention discloses a hollow pneumatic motor with an outer motor, wherein blades (29) can be movably embedded into a blade groove (211) in a rotor body (21) radially; a spring (262) is movably mounted in the inner cavity (2611) of a spring pressure lever (261); the spring pressure lever (261) is fixed to the rotor body (21); all spring pockets (262) are contacted with the outside of each blade (29); through holes (14) are arranged in the position of a fixing shaft (1) slightly deviating a central axis; at least two air inlet / outlet pipes (11, 15) are arranged in the fixing shaft (1); one end of the air inlet / outlet pipes (11, 15) is respectively connected with different air cavities (27) of the rotor (2); the other end of the air inlet / outlet pipes is respectively connected with the outer air source or the discharging air pipe. The pneumatic motor enables the liquor stream to pass through the through holes (14) in the fixing shaft, the problem of filtering media bulking and filtrate distributary in the sewage-treatment filtration equipment. The hollow pneumatic motor with outer motor has the advantages with simple structure and easy production, and thus it is applied to the sewage-treatment equipment in the environmental protection field.

Description

technical field [0001] This invention relates to rotary piston machines or engines, other than internal shaft rotary machines, and more particularly to external rotor air motors with hollow water passages. Background technique [0002] The air motor in the prior art includes a stator housing and an inner rotor, and the inner rotor is installed at the central axis of the stator housing. However, in the sewage treatment and filtration engineering system in the field of environmental protection, the inner rotor air motor in the prior art is not suitable for the engineering system because the air motor is required to work in water and there is liquid flow inside the air motor. Contents of the invention [0003] Aiming at the disadvantage that the inner rotor air motor is not suitable for the sewage treatment and filtration engineering system in the field of environmental protection, the technical problem to be solved by the present invention is to avoid the disadvantages of th...
