Definitions
- the invention relates to a rotatable Separatortrommel with a vertical axis of rotation according to the preamble of claim 1 or 2.
- a respective generic separator drum is known, for example, from DE 19519693 C1 or DE 10 2006 047478 A1, wherein the plate-like component is the distributor foot, which on its underside has a substantially conical shape and therefore an exemplary plate-like shape.
- the distributors serve to guide the product to be processed from an inlet pipe through flow channels - also called distribution channels - into the drum.
- This construction has proven itself.
- the problem is that the flow channels, especially in the processing of products containing abrasive solids, are exposed to increased wear, which can adversely affect the life of the distributor.
- Similar problems can occur on other elements of the separator drum, in particular on plate-like components such as separator plates, on drum parts or on plates which are attached to the inner surfaces of the drum parts. For example, on divider plate, the flow goes from outside to inside, otherwise from the inside out.
- the invention has the object to reduce this problem.
- the invention solves this problem by the subject matter of claim 1 and the subject of claim 2.
- At least one dam weir is arranged in each case in the region between the inlet opening and the outlet opening in the at least one flow channel. in front of which an accumulation of solids forms during operation when processing a product containing solids.
- the plate-like component on at least one surface is particularly preferably a foot section of a distributor which is connected in a rotationally fixed manner to the drum, wherein the foot section is provided with at least one or more of the flow channels, which preferably extend radially outwardly at an angle to the axis of rotation at least one of the weirs is arranged in the region between the inlet opening and the outlet opening in the at least one flow channel.
- the weir is designed in such a way that during operation of the processing of a solids-containing product (in the direction of flow from the inside to the outside) in front of the weir, an accumulation of solids is formed.
- This material accumulation (s) act in the operation of the separator as a wear protection for the plate-like part, in particular for the Verteilerfußabdeckung.
- the object of the invention is achieved in a comprehensive manner by simple means.
- Fig. 1 is a schematic view of a separator drum
- FIG. 2 shows a section through a known distributor for a separator drum.
- Fig. 3 is a perspective view of a flow channel of a distributor according to the invention.
- FIG. 1 shows a separator drum 1 with a vertical axis of rotation D, which has a centric feed pipe 2, which opens into a distributor 3.
- the distributor 3 has at its inlet a centric inlet pipe section 4 in the axial extension of the inlet pipe 2, which merges into a foot section 5.
- flow channels 6 extend radially outward at an angle in the base section 5, preferably at an acute angle or at right angles to the axis of rotation.
- the flow channels 6 run obliquely downwards with respect to the axis of rotation, but they could also be directed at an acute angle from the feed pipe section 4 obliquely upwards.
- a separation plate stack 7 is arranged from separation plates 8.
- Discharges 9, 10 for at least one or more liquid and preferably a solid phase are used to derive the separated and / or clarified phases from the drum 1.
- the distributor 4 is attached by suitable means to the drum 1.
- the product flow is indicated by arrows.
- the flow channels 6 extend in the distributor foot 5 from inlet openings 11 into the flow channels up to outlet openings 12 from the flow channels 6 into the interior of the centrifugal drum.
- the flow channels are covered by a conical distributor foot cover 13. Laterally or in the circumferential direction, the flow channels 6 are bounded by wall sections 14. In any case, at the bottom of the Verteilerfuß- cover plate-like.
- FIG. 3 illustrates a kind of view under the distributor foot 13, which narrow the cross-section of the flow channel in this area.
- the weirs 15 are formed as ribs. These ribs 15 are preferably arranged or formed in the transition region between one of the side walls 14 and the Verteilerfußabdeckung 13, in particular in the transition region between the rear in operation U wall portion 14 and the Verteilerfußabdeckung 13. In the circumferential direction, the flow channels 6 here separated from each other by the wall sections 14. Particularly preferably, the ribs in this area on a triangular portion 16 which extends on the underside of the Verteilerfußabdeckung 13 over part of the circumferential length of the flow channel 6 and then merges into a web section 17.
- the substantially triangular section 16 may also have, for example, a curved shape in the region of its base side 18.
- the height H of the sections 15 and 16 is at least 2 mm or more. Preferably, more than three weirs are distributed in each flow channel 6. The goal is that, as far as possible, a continuous wear-resistant coating is formed on the underside of the distributor foot cover 13.
