DE102007028102A1 - Rotatable separator drum, has barrage arranged in region between inlet and outlet openings of flow channel, and solid mass formed before barrage and during processing of solid matter containing product - Google Patents

Abstract

The drum (1) has a vertical rotary axis (D), and a flow channel (6) with an inlet opening (11) and an outlet opening (12). A barrage is arranged in a region between the inlet and outlet openings of flow channel. A solid mass is formed before the barrage and during the processing of a solid matter containing product. A rib is formed in the transmission region between one of a side wall and a compressor base cover. The rib comprises a triangular section, which crosses over at the lower side of compressor base cover in a base section.

Description

The The invention relates to a rotatable Separatortrommel with a vertical Rotary axis according to the preamble of claim 1 or 2.

A respective generic separator drum is for example from the DE 19519693 C1 or the DE 10 2006 047478 A1 known, wherein the plate-like component is the distributor foot, which has on its underside a substantially conical and therefore insofar exemplary plate-like shape.

The Distributors are used to process the product to be processed from an inlet pipe through flow channels - here also distribution channels called - to lead into the drum. This construction has proven itself. However, the problem is that the flow channels in particular in the Processing of products containing abrasive solids, are exposed to increased wear, the may adversely affect the life of the distributor. Analogous problems can occur on other elements of the separator drum, especially on plate-like components such as dish plates, on drum parts or sheets, which are on the inner surfaces the drum parts are mounted occur. For example, on Scheideteller the flow goes from outside to inside, otherwise from the inside to the outside.

The Invention has the task to reduce this problem.

The Invention solves this problem by the subject matter of the claim 1 and the subject of claim 2.

After that is in each case in the area between the inlet opening and the exit opening in the at least one flow channel arranged at least one weir, in front of which in operation at the Processing a solids-containing product accumulation of solids formed.

Especially this is preferably plate-like on at least one surface Component a foot section of a distributor, with the Drum is rotatably connected, wherein the foot section with at least one or more of the flow channels is provided, which is at an angle to the axis of rotation, preferably radially extend outward, being in the area between the Inlet opening and the outlet opening in the at least one flow channel of at least one of the weirs is arranged.

The Weir control is designed in such a way that during operation during processing a solids-containing product (in the flow direction from inside to outside) in front of the weir we see a build-up of solid matter formed. This material accumulation (s) work in operation of the separator as a wear protection for the plate-like part, in particular for the Verteilerfußabdeckung. The object of the invention is thus encompassed by simple means solved.

advantageous Embodiments of the invention are the subclaims refer to.

following The invention will be described with reference to the drawing based on embodiments described in more detail, wherein also further advantages of the invention be explained. It shows:

1 a schematic view of a separator drum;

2 a section through a known distributor for a separator drum;

3 a perspective view of a flow channel of a distributor according to the invention.

1 shows a separator drum 1 with a vertical axis of rotation D, which is a centric inlet pipe 2 that is in a distributor 3 empties. The distributor 3 has at its entrance a centric inlet pipe section 4 in axial extension of the inlet pipe 2 on that in a foot section 5 passes.

To the centric inlet pipe section 4 close in the foot section 5 circumferentially distributes angularly, preferably at an acute angle or at right angles to the axis of rotation radially outwardly extending flow channels 6 at. The flow channels 6 run here with respect to the axis of rotation here obliquely down, but they could also acute angle of the supply pipe section 4 be directed diagonally upwards.

In the drum 1 is a separator plate stack 7 from separation plates 8th arranged. derivations 9 . 10 for at least one or more liquid and preferably a solid phase are used for the derivation of the separated and / or clarified phases from the drum 1 , The distributor 4 is by appropriate means on the drum 1 attached. The product flow is indicated by arrows.

The flow channels 6 extend in the distributor foot 5 of entrance openings 11 into the flow channels up to outlet openings 12 from the flow channels 6 in the interior of the centrifugal drum.

At the top, the flow channels of a here conical Verteilerfußabdeckung 13 covered. Laterally or in the circumferential direction, the flow channels 6 of wall sections 14 be borders. In any case, at the bottom of the Verteilerfußabdeckung is plate-like.

In the area between the inlet openings 11 and the outlet openings 12 are in the flow channels, of which 3 one under the look of the distributor foot 13 illustrates several weirs 15 arranged, which narrow the cross-section of the flow channel in this area.

Preferably, the weirs are 15 designed as ribs. These ribs 15 are preferably in the transition region between each of the side walls 14 and the distributor foot cover 13 arranged or formed, in particular in the transition region between the rear in operation in the direction of rotation U wall section 14 and the distributor foot cover 13 , In the circumferential direction are the flow channels 6 here through the wall sections 14 separated from each other.

Particularly preferably, the ribs in this area have a triangular section 16 on, located at the bottom of the distributor foot cover 13 over part of the circumferential length of the flow channel 6 extends and then into a web section 17 passes. The essentially triangular section 16 can be in the range of its base page 18 also have, for example, an arch shape. The height H of the sections 15 and 16 is at least 2 mm or more. The section 16 preferably extends to the next side wall in the circumferential direction 14 , Preferably, more than three weirs are in each flow channel 6 The goal is to have a continuous wear-resistant coating on the underside of the distributor foot cover over time 13 formed.

In the direction of flow - which extends radially from the inside to the outside - are formed in the flow direction from the inside to the outside in front of the ribs 15 In the flow channels accumulation of material or a layer of material from the solid, which is unproblematic in the processing of hygienic non-critical products on the one hand and on the other hand advantageous as wear protection and thus increases life.
