Device for collecting and discharging solid matter

A device for collecting and discharging solid matter from a liquid-solid mixture flowing in a conduit in a waste collecting stream, comprising:

• an inclined grid structure formed by a series of stationary bars defining a stationary grid and a series of displaceable bars defining a displaceable grid and alternating with the stationary bars, the bars being arranged obliquely in a conduit adapted to be positioned in a waste collecting stream containing a liquid-solid mixture, with the grid structure having an upper portion of sufficient length so as to extend above the surface of the waste collecting stream, with displaceable bars positioned at the outermost position of the series,
• a plurality of the stationary bars and the displaceable bars having edges curved back in the general ascending direction of the inclined grid structure so as to be turned toward the flow of the waste collecting stream,
• the stationary bars and the displaceable bars being arranged to form generally uniform steps having terraces on which solid matter from the waste collecting stream may be deposited,
• vertical side plates formed on the outermost displaceable bars which move in tandem with the displaceable bars so as to prevent any solid matter from falling along the sides of the grid structures,
• means interconnecting the displaceable bars into one unit in the displaceable grid,
• saw teeth formed on selected combinations of the stationary bars so as to prevent the displaceable bars from becoming blocked at the interconnecting means, driving means having a power source and a connecting means connected to the vertical side plates such that, when the power source is engaged, the driving means will impart a movement to the vertical side plates in said one unit so that at any point the edges of the displaceable bars will perform a generally closed circuitous path of movement including at least one vertical component of movement within each path, to cause solid matter collected at the grid structure to move upwardly along the displaceable bars, and
• a compacting conveyor including a reciprocal piston located so as to receive matter lifted to the upper end of said grid structure and feed it into a delivery conduit.

A device including a grid structure located in a conduit for collecting and discharging solid matter from a waste collecting stream having a liquid-solid mixture therein, comprising:

• an inclined grid structure formed by a series of stationary bars defining a stationary grid and a series of displaceable bars defining a displaceable grid, the displaceable bars alternating with the stationary bars, the series of stationary and displaceable bars being configured to form steps, and further with displaceable bars being placed at outermost positions of the series,
• the stationary and displaceable bars having means to retard the downward movement of solid matter on the inclined grid structure,
• displaceable vertical side plates affixed to the outermost displaceable which move in tandem with the displaceable bars and are displaceable therewith so as to substantially prevent any solid matter from falling along the sides of the grid structure,
• the stationary bars and the displaceable bars being inclined at an angle such that, in use, any solid matter collected on the bars will be substantially prevented from falling back down the inclined grid structure,
• means including a beam structure connected to the displaceable vertical side plates and running transversely below the displaceable bars and positioned on the inclined grid structure so as to be above the waste collecting stream for interconnecting at least two of the displaceable bars,
• driving means having a power source and a connecting means connected to the displaceable vertical side plates such that, when the power source is engaged, the driving means will impart a movement to the displaceable vertical side plates in the at least one unit so that at any point the edges of the displaceable bars will perform a generally closed circuitous path of movement including at least one vertical component of movement within each path to caorm a generally closed circuitous path of movement including at least one vertical component of movement within each path to cause solid matter collected at the grid structure to move upwardly along the displaceable bars.
