IPC: B08B9/08
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently assure a filter area and to continuously perform cleaning work by using a wire net of an inverted conical shape for a filter, dropping filth onto the outer edge of the filter by a diffusion plate and filtering the filth while moving the filth toward an inner peripheral side by the effect of gravity. SOLUTION: The filth flowing from a suction hose 23 into a housing 1 diffuses to the circumference along the disk-shaped diffusion plate 22 fixed to a cap 20 by four supporting members 21 and is dropped from the outer periphery of the diffusion plate 22 onto the filter section 2 having the inverted conical shape. The moisture of the filth falling onto the filter section 2, i.e., sewage, falls through the meshes of the filter section 2 and the remaining solids of the filth separated from the sewage fall downward along the slope of the cone. The sewage falls down to the lower part of a housing 1 and is discharged outside the housing 1 from a piping 12 by the suction force of a suction pump. The solid filth falls down to a housing section 3 by passing a communicating section 30.  The solid filth accumulates on the meshes of the filter section 2 and, therefore, a motor 7 is actuated to rotate a scraper 4 via a shaft 5.

Abstract: PURPOSE:To improve the surface brightness of a diffusion plate by forming the peak parts of a reflection plate as specular surfaces to reflect light and forming the valley parts as scattering surfaces to scatter the light. CONSTITUTION:The reflection plate 13 is formed to the shape projecting at 5 points to the diffusion plate 11 side, i.e., upward and has the peak parts 13M and the valley parts 13V existing between the peak parts 13M.

On the other hand, the downward light from the fluorescent lamp 13 is scattered by the scattering surfaces 13V' and a part of the scattered light is efficiently reflected by the specular surfaces 13M to improve the surface brightness of the diffusion plate 11 right above the center between the fluorescent lamps 12 and 12. The upward light from the fluorescent lamp 12 is added to the light from the reflection plate 13, by which the unequalness of the surface brightness of the diffusion plate 11 is minimized.
