screening device

Abstract

A screening device comprising: a container (1) through which a liquid containing solids, in particular liquid manure containing foreign bodies, can be pumped so that it flows from an inlet (13) to an outlet (15) of the container (1), a screen (29) for separating solids, which is arranged between the inlet (13) and the outlet (15) and extends between a container bottom (3) and a container top (9), and a flow barrier (37) arranged between the screen (29) and the inlet (13) and designed to deflect liquid flowing in through the inlet (13) so that at least some of the solids separate on the container bottom (3), the liquid flows through between the flow barrier (37) and the container bottom (3) and flows onto the screen (29), wherein the flow barrier (37) and the container bottom (3) are designed to deflect the liquid containing the solids in such a way to distract,that at least some of the solids are separated from the liquid on the container bottom (3) before flowing through the sieve (29), in that solids no longer follow a flow movement of the liquid when swirled by the flow barrier (37) and the container bottom (3) and are already separated on the container bottom (3) before the sieve (29).

Claims

[1] Screening device with - a container (1) through which a liquid containing solids, in particular liquid manure containing foreign bodies, can be pumped so that it flows from an inlet (13) to an outlet (15) of the container (1), - a sieve (29) for separating solids, which is arranged between the inlet (13) and the outlet (15) and extends between a container bottom (3) and a container top (9), and - a flow barrier (37) arranged between the screen (29) and the inlet (13) and designed to deflect liquid flowing in through the inlet (13) so that at least some of the solids are deposited on the container bottom (3), the liquid flows through between the flow barrier (37) and the container bottom (3) and flows onto the screen (29) - wherein the flow barrier (37) and the container base (3) are designed to deflect the liquid with the solids in such a way that at least some of the solids are separated from the liquid on the container base (3) before flowing through the sieve (29), in that solids no longer follow a flow movement of the liquid when swirling is caused by the flow barrier (37) and the container base (3) and are already separated on the container base (3) in front of the sieve (29). [2] Screening device according to claim 1, wherein a pumping device can be connected to the outlet (15) and / or the inlet (13), which pumping device is designed to pump the liquid through the screening device. [3] Screening device according to one of the preceding claims, wherein the inlet (13) has a check valve (27). [4] Screening device according to one of the preceding claims, wherein the inlet (13) is arranged in an upper region of an end face (5) of the container (1). [5] Screening device according to claim 4, wherein the outlet (15) is arranged in a container top (9) and adjacent to the opposite end face (5). [6] Screening device according to one of the preceding claims, wherein the screen (29) is arranged between side walls (7) at an angle to the longitudinal axis of the screen device. [7] Screening device according to one of the preceding claims, wherein the screen (29) has a grid-shaped screen lining (31). [8] Screening device according to one of the preceding claims, wherein the flow barrier (37) is designed as a wall extending in an upper container region between the side walls (7). [9] Screening device according to claim 8, wherein the wall as which the flow barrier (37) is formed does not extend to the container bottom (3). [10] Screening device according to one of the preceding claims, wherein the flow barrier (37) is arranged at an angle to the longitudinal axis of the screening device. [11] Screening device according to one of the preceding claims, wherein the flow barrier (37) extends at an angle, in particular perpendicular, to the flow direction of the inflowing liquid. [12] Screening device according to one of the preceding claims, wherein the container (1) has a hinged or removable lid (11). [13] Screening device according to one of the preceding claims, wherein the container (1) has a drain (17) for draining the liquid from the container. [14] Screening device according to one of the preceding claims, which is designed to be mobile and / or can be coupled to a tractor.
