Definitions
- the invention relates to a device for conveying, crushing and mixing conveyed material with and without solids content.
- the device is used in particular in wastewater management and in every branch of industry in which the flow phase has to be homogenized, dispersed or treated. Another application is in the field of mixing processes.
- the stator consists of a cylindrical drum with inwardly directed teeth which mesh with the teeth of the rotor at a distance.
- the inside of this stator drum is in flow connection to the inlet opening via an end opening and to the outlet opening via slots or bores provided in the region of this outlet opening in the cylinder wall of the stator.
- the rest of the cylinder wall has no openings.
- stator drum is designed as a one-piece component, the teeth projecting inwards having to be produced in a costly manner on a lathe.
- the drum is to be provided with slots or openings at the predetermined point, so that the material to be conveyed can exit the interior of the drum in the region of the discharge opening.
- a further disadvantage is that the material to be conveyed can only pass through the stator cylinder wall at the point of the discharge opening, so that there is a constriction here for the material flow.
- the stator wall consists of a one-piece cylinder, which is provided on the inside with zanniform ribs. Openings are formed in the ribs to enable the material to flow through the screw-shaped discharge gap to the discharge opening.
- a conveyor for suspensions and viscous substances with a basket-like perforated housing is known.
- This housing consists of adjacent rack-like elements, which are received in their respective ends in ring grooves. These ring grooves are formed on flanges that form the upper and lower edges of the basket-like housing. In order to keep the racks at a distance, projections are formed on the side walls, which are supported on the respective neighboring element.
- This design has the disadvantage that an additional material accumulation can take place in the gap between the rack elements, which builds up on the projections.
- the invention has for its object to provide a device of the type mentioned, the stator ensures simple and inexpensive training an undisturbed outflow of the material to be conveyed.
- the stator cylinder now essentially consists of two fixing rings, which are each arranged on the end face, and of a large number of toothed racks, which are particularly easy to manufacture in terms of production.
- the fixing rings are advantageously equipped on their circular outer circumference with wings, the thickness of which in the circumferential direction defines the spacing of the toothed racks and thus the gap width between the toothed racks. This measure eliminates the costly machining to produce through openings for the material to be comminuted or comminuted.
- the wings are provided on the fixing ring only over part of the circumference of the fixing ring and the Racks are arranged side by side in the remaining peripheral area without a gap.
- the toothed racks may also be expedient to design the toothed racks as a two-component part, the toothed part of the toothed rack being able to consist of a material which is adapted to the later field of application of the device.
- This tooth part can be soldered or screwed to the carrier part.
- the housing has a helical cross section, the discharge gap between the outer circumference of the stator and the inner wall of the housing continuously widening in the circumferential direction towards the discharge opening.
- a particularly advantageous measure can be seen in the fact that the gap between the toothed racks of the stator and the gap distance between the teeth of the stator and the rotor that passes by is the same. In this way the Shredding effect not only between the teeth brushing past each other, but also caused by the passage of the conveyed material through the gap between the toothed racks, whereby the quality of the shredding and the efficiency are significantly increased.
- FIG. 1 is a sectional view of a device for conveying, crushing and mixing of conveyed material with and without solids content, as is common in wastewater technology.
- the device has a housing 2 with a shaft stub 3 projecting into it, on which a rotor 7 is attached in a rotationally fixed manner.
- the housing 2 is provided on the end face with an entry opening 4 and at an angle to the shaft axis 5 with an exit opening 6.
- the discharge opening 6 can intersect the shaft axis with its axis or be suitably located tangentially to a suitable circumferential diameter in such a way that a favorable flow behavior is achieved.
- a cylindrical stator 8 is received in the housing, in which the rotor fixed on the stub shaft 3 rotates.
- the cylindrical stator 8 has an annular toothing 9 which meshes with teeth correspondingly formed on the rotor 7.
- the rotor consists of an inclined disc, as is known in the prior art. Because of the oblique arrangement leads the disc wobbles in the axial direction, with the result that a pumping action is brought about due to the centrifugal acceleration of the conveyed material.
- the stator 8 consists of individual racks 13, which are each held at the cylindrical ends of the stator by two fixing rings 15.
- the fixing rings 15 have on their outer circumference, depending on the application, over the entire outer circumference or only over a partial area of wings 16 (see FIG. 2), which, due to their material thickness, define the gap distance 17 between the toothed racks 13.
- a discharge gap 20 is provided between the outer wall 21 of the cylindrical stator 8 and the inner wall 22 of the housing 2, which has a constant width over the entire circumference.
- the housing is offset eccentrically to the shaft axis 5 or is designed to widen in a helical shape, so that the discharge gap widens continuously over the circumference and the material to be conveyed can flow more easily over the entire stator circumference to the discharge gap and to the discharge opening 6.
- the racks of the cylindrical stator 8 are fixed over the entire circumference with a gap distance to the adjacent rack on the fixing rings 15, so that the material to be conveyed and crushed can escape over the entire circumferential surface of the cylinder and thus offers only an extremely low flow resistance .
- FIG. 6 shows a three-bladed rotor, the teeth of which are designed as a separate tooth part 23.
- the toothed part 23, in FIG. 3 in a single illustration, has a device in the area facing the rotor for fixing the toothed part to the actual rotor.
- this device consists of a projecting tab 24 which can be inserted into a corresponding cutout in the rotor and screwed there.
- this toothed part can be made in two parts, the actual toothed area 18 consisting of a hardenable or hardened material, the actual support area (19) consisting of a simple cast steel that is adapted to the function.
- FIG. 5 shows a further type of fastening for the tooth part on the rotor in section, the fixing being carried out either by means of a soldered connection or by means of a screw connection at the end.
- the design of the stator cylinder in the form of racks standing next to one another at a distance makes it possible to make the gap 28 between the teeth of the stator and the teeth of the rotor particularly narrow, a distance dimension which has proven particularly advantageous to correspond to the distance dimension of the racks from one another , such as 1.6 mm rack distance and 1.6 mm distance between the teeth of the rotor and the teeth of the stator.
