1. Introduction:
The rotary mechanical bar screen machine (grilling spotter) is a kind of solid-liquid separation device, which can continuous automatic eliminate all kinds of figure sundries in the fluid. It is widely used as special equipment in urban sewage treatment, water supply industry and electric plant water inlet. At the same time, it can be seen as essential special equipment in the production processing of textile, food processing, paper making, leather etc. industry , which is the most advanced Solid-liquid separation equipment in China.
2. Structure and working principle
A rotary bar screen is mainly composed of a driven device, a rake tooth facility ,a flush facility etc., which is assembled to be a group of rotary bar screen chain by a unique rake tooth. Driven by Motor reducer, the rake tooth chain goes Rotary motion as reverse flow.
When the rake tooth chain operates to upside of equipment, due to the guiding of Geneva wheel and curve, which produces the relative self-cleaning motion between each group rake tooth, most of the solid drop down by gravity. Another part clean up the sundries sticking in the rake tooth by sweeper‘s reverse movement.
Rake tooth chain is similar to grilling by water flow direction, the rake tooth clearance which assembled in rake tooth chain shaft can be chose according to usage condition , which can guarantee water flow pass by smoothly after the rake tooth separates the suspended solid in the fluid. The whole process can be continuous and intermittent.
