RESEARCH BENCH FOR SAPROPEL TRANSPORT-AND-PRODUCING COMPLEX Russian patent published in 2007 - IPC E02F3/88 

FIELD: dredgers, soil-shifting machines with arrangements acting by a sucking or forcing effect, for instance suction dredgers.

SUBSTANCE: research bench comprises drag-chain loop provided with drive and closed in vertical plane. The drag-chain loop has separable load-carrying and idle branches which may pass over driving and reversing sprockets. The bench also has vertically fixed guiding gutter secured to support member. The guiding gutter with load-carrying branch of drag-chain loop arranged in it is connected to bottom of chamber to be filled with sapropel mass. The chamber is made as triangular prism having vertically directed bases. One reversing sprocket is located inside the chamber, another idle sprocket and driving sprocket are arranged over upper chamber surface. The gutter is located on one side prism wall, which defines chamber bottom. The chamber is attached to frame by means of horizontal hinge and provided with screw tie, which connects the chamber with frame carrying gauging tank so that sapropel mass may be discharged into the tank from load-carrying branch of drag-chain loop. The chamber is provided with angular instrument. The drive has means to regulate drag-chain loop movement speed.

EFFECT: increased range of device parameters to be researched, possibility to optimize device parameters to minimize power inputs and to maximize output of the complex.
