Definitions
- the invention relates to a disintegrator for the very fine comminution of inorganic substances with a predominantly crystalline structure and of deep-frozen organic substances, as well as of corresponding substance mixtures, with two rotors driven in opposite directions, which carry at least four alternating intermeshing rows of blades arranged concentrically in a ring shape, which transport the substance from the inside Get out through the rows of blades, the blades being inclined forward and outward in the direction of rotation.
- Disintegrators have already been proposed in different embodiments for the very fine comminution of materials.
- a disintegrator is to be used, which is to be designed and operated in such a way that at least three successive impacts on each material particle with a time interval between two successive impacts of a maximum of 0.05 sec are guaranteed.
- the impacts on the particles caused by the impact body or by other particles should be at a speed of at least 1S m / s.
- This impact treatment is said to subject the material to activation which gives the material new and significantly improved properties.
- the disintegrator proposed for this purpose is equipped with beater bars which are circular in cross section and which are subject to extremely high wear.
- the rotors are mounted on one side, ie overhung, so that the high speeds required in the interest of good activation cannot be achieved because of dangerous vibration phenomena which inevitably occur.
- a protective layer which reduces the wear on the blades and which consists of the material to be shredded is automatically formed on the working surfaces of the blades .
- the blades are concave on their active surfaces in the interest of improved formation and maintenance of the protective layer.
- the leading and trailing edges of the blades can be reinforced by cutting inserts made of hard, abrasion-resistant material.
- the impactors ie the blades
- the maximum speeds that can be achieved are also limited by the one-sided, ie overhung bearing of the rotors, so that optimal activations of the comminution material cannot be achieved.
- the invention has for its object to provide a disintegrator, the blades of which are subject to comparatively little wear and the rotors of which can be driven at high speeds which are desirable for effective fine comminution and activation.
- the disintegrator should be suitable for technically flawless and economical fine grinding of a wide range of different materials.
- the stated object is achieved on the basis of a disintegrator of the type specified at the outset in that the blades are essentially curved in the manner of radial turbine blades, the concave curvature in each case in the direction of rotation at the front, and in that the rotors are fastened to respectively assigned hollow shafts which are rotatably mounted on a common fixed axis.
- the inventive design of the blades results in a turbo effect in the operation of the disintegrator, the immediate effect of which is that; that the blades mainly take on a guiding function for the materials to be shredded and the gas or air throughput and only serve as impact tools to a small extent.
- the bearing of the rotors via hollow shafts on a common fixed axis not only allows the disintegrator to run up and run continuously without vibrations, it also enables such speeds that the outer blade ring has peripheral speeds close to the speed of sound lend.
- an extremely effective micronization and activation is achieved, which can be maintained over economically long operating periods due to the reduced blade wear.
- the materials comminuted with the disintegrator according to the invention have unique properties with regard to the degree of comminution and the activation achieved. What is striking is the observation that the shredded materials do not tend to agglomerate.
- the comminution material also forms a wear-reducing protective layer on the active surfaces of the blades of the disintegrator according to the invention.
- leading and trailing edges of the blades can be protected against wear. This can advantageously be done in that the leading and trailing edges of the blades or their wear tabs are armored with a material whose material properties result from a legally derived "high position" between the comminution material and the blade material.
- relief bores are provided in the rotor disks between the first and third and between the second and fourth blade rings. These relief bores ensure pressure equalization between the individual chambers formed between the blade rings, as a result of which the wear on the blade end faces and the adjacent rotor disk regions is reduced.
- the housing surrounding the rotors is advantageously horizontally divided in the plane of the fixed axis and is sealed with respect to the hollow shafts led out of the housing, but is not non-positively connected to them.
- the arrangement is expediently such that the housing and the fixed axis supporting the rotors via the hollow shafts are arranged separately on a common base plate.
- the hollow shafts of the disintegrator can be directly connected to the drive motors via flat V-belts or via flanged gears with an intermediate coupling.
- a start control of the motors is expediently available.
- the method for operating a disintegrator which is part of the invention, is characterized in that the substances to be comminuted are forcibly dosed to the disintegrator and adjusted in quantity using gravity, and the comminuted substances are discharged from the disintegrator in accordance with the comminution performance using the force of gravity, and that Gas stream passing through the disintegrator is partially circulated between the feed zone and the discharge zone.
- This intended circulation enables the disintegrator according to the invention the peculiar different behavior of the air or gas flow when idling on the one hand and under load running on the other hand. It has been found that the disintegrator passes through the air or gas flow from outside to inside when idling, while this flow direction changes in the opposite direction during load running.
- the method for operating the disintegrator is furthermore advantageously characterized in that the disintegrator is operated in a closed comminution circuit with an airtight and gas-tight seal at the feed and discharge zone.
- the hollow shaft bearings of the disintegrator are circulated Run lubricated oil are lubricated, and that this oil flow is used with the help of its parameters pressure, temperature and quantity for protection and temperature control of the disintegrator.
- FIGS. 1 and 2 To explain the basic structure of the disintegrator, reference is first made to FIGS. 1 and 2.
- a fixed, rigid and cylindrical axis 3 is non-rotatably attached via lateral supports 2 attached to it.
- the separate drive of the hollow shafts 4 and 5 via flat V-belts or via flanged gearbox with intermediate coupling, and the two drive motors are not shown in Fig. 1.
- a rotationally symmetrical rotor In a plane perpendicular to the axis 3, a rotationally symmetrical rotor, generally designated by the reference number 7, is attached to the hollow shaft 4.
- a rotor generally designated 8 is fastened in a corresponding manner to the hollow shaft 5.
- the rotors 7 and 8 are driven in opposite directions via the respectively associated hollow shafts 4 and 5, as the direction of rotation arrows 9 and 10 indicate.
- the rotors 7 and 8 have full disks 11 and 12, respectively, on which the respectively associated blade rings are fastened, which are only indicated schematically in FIG. 1.
- the rotor 8 carries the first or inner blade ring 13 and the third blade ring 14.
- the second blade ring 15 and the fourth or outer blade ring 16 are fastened to the rotor 7.
- the vane rings 13 to 16 alternately intermesh in the sense that each vane ring of one rotor is followed by a vane ring of the other rotor viewed in the radial direction.
- the blade rings are of course arranged concentrically to one another and to the hollow shafts 4 and 5 and to the fixed axis 3.
- the base plate 1 has in the example shown a recess for the passage of the rotors 7 and 8 and a housing surrounding the rotors, which is horizontally divided in the plane of the fixed axis 3 and therefore consists of a lower part 17 and an upper part 18.
- Upper part and lower part can be known not be shown in more detail connected by releasable connecting means.
- the housing is firmly connected to the base plate via its lower part 17.
- the hollow shafts 4 and 5 are sealed at 19 and 20 and lead out of the housing 17, 18, to which they are not non-positively connected, however. Sealing at the hollow shaft passages 19 and 20 can be carried out, for example, by a sealing gas supplied under pressure.
- the housing 17, 18 has an inlet connection 21 which opens into the interior of the disintegrator, which is delimited by the rotor disk 12, the blade ring 13 and a housing wall. At the lower end, the lower housing part 17 has a discharge opening 22. Arrows 23 and 24 mark the throughput direction of the materials to be crushed by the disintegrator.
- each blade ring 13 to 16 is shown for the sake of simplifying the drawing, which blade is also shown in different exemplary embodiments.
- the blades of the different blade rings can also have corresponding or similar geometric configurations. It is characteristic of all blades that they are essentially curved in the manner of radial turbine blades, so that special flow conditions resulting from the aforementioned turbo effect result in the channels formed by adjacent blades of a blade ring can form. As can be seen, the concave curvature of all blades is in the direction of rotation (arrows 9 and 10) at the front.
- the blades 25 of the outer blade ring 16 are equipped with an outwardly facing projection 26 located in the direction of rotation at the rear, which forms an outer deflecting surface 27 which forms an angle ⁇ of approximately 80 ° with the blade position marked by the auxiliary line 28.
- the angle ⁇ between the blade position 28 and the circumferential direction marked by the auxiliary line 29 is between 20 and 32 °. This angular range is also used for the corresponding angles ⁇ of the other blade rings 13 to 15.
- the circumferential direction 29 is the perpendicular to the radial line 30 passed through the leading edge of the blade 25.
- the angles oC of the blades of the other blade rings are defined accordingly.
- the example of the blade 31 of the blade ring 14 demonstrates the attachment of wear lugs 32 and 33 at the blade inlet and at the blade outlet. These wear lugs 32 and 33 reduce the wear of the blade 31 in the sense that the wear lugs can be slowly reduced by wear without impairing the blade effectiveness.
- a possible blade design without wear lugs is shown using the example of the blade 34 of the blade ring 15.
- blades 25, 31, 34 produced in one piece blades welded together from several parts can also be used, as is shown using the example of the blade 35 of the blade ring 13.
- the blade 35 consists of two Flat pieces 36 and 37 welded to one another at an obtuse angle. It is also possible to weld more than two pieces to one another in order to approximate the shape of the blade to a curved shape of the blade.
- the blades In order to protect the leading and trailing edges of the blades against wear, they can be provided with an armored material, as is schematically indicated at 38 in the example of the blades 34 and 35. Corresponding armouring 39 can also be attached to the wear lugs, if present, as indicated by the wear lugs 32 and 33 of the blade 31 of the blade ring 14.
- the full rotor disk 11 of the rotor 7 has relief bores 40 between the blade rings 15 and 16 for pressure equalization.
- Corresponding relief bores 41 are made in the rotor 8, specifically in an annular disk 42 connecting the two blade rings 13 and 14 to one another.
- FIG. 4 A system integration of the disintegrator is shown in FIG. 4.
- the two drive motors 43 and 44 can also be located on the base plate 1.
- the materials to be shredded are fed to the inlet connection 21 of the disintegrator via controllable and force-dosing cellular wheel locks 45 and 46, an adjoining downpipe 47, a feed zone 48 and a compensator 49.
- the comminuted material leaves the disintegrator via a compensator 50, a discharge zone 51 and a downpipe 52 and is fed from there to two further discharge rotary valves 53 and 54.
- To the Feed zone 48 and discharge zone 51 are connected to an air or gas circulation line 55, in which arrows drawn in both possible flow directions indicate the flow change between empty operation and load operation.
- the circulation lines 55 can also be installed in the disintegrator housing itself as flow channels. Air or inert gas is supplied to the system via line 56 during load operation. Air or gas is supplied in idle mode via line 57. Any air or gas overpressure can escape from the system via line 58, which leads to a filter. A gas connection 59 can also open directly into the circulation line 55.
- the disintegrator can be operated in an air-tight and gas-tight seal at the feed and discharge zone in a closed comminution circuit, so that the dusts produced during the comminution process cannot escape to the outside.
- the disintegrator according to the invention was used, for example, for comminuting different minerals up to a Mohs hardness of 9.3 at throughputs between 6 and 8 t / h.
- the maximum rotor diameter ie the maximum diameter of the rotor 7 on the outer blade ring 16, was 750 mm.
- the average grain size of the feed was about 12 mm.
- a fly ash made of lignite coal with the following chemical composition was used
- This electrostatic precipitator ash had an average grain size before disintegration of 200 ⁇ m.
- the specific surface area according to Blaine was approximately 4200 cm 2 / g. After disintegration, the grain size was only about 20 ⁇ m and the specific surface area was 9195 cm 2 / g. After subsequent sighting at
- Fine fraction the specific surface area was 13,360 cm 2 / g.
- the average residence time of the particles to be comminuted in the disintegrator was less than 1 sec.
