Description

The present invention relates to an apparatus and a method for processing materials. In particular, the invention relates to a cleaning apparatus and a method for processing materials containing granular material excavated from deposits and / or a cleaning apparatus and a method for crushing lumpy foreign matter such as loam or the like contained in raw gravel. A use in the field of recycling of, for example, slags, building materials is possible.

In the prior art, various cleaning devices for processing materials have become known.

With the DE 2 812 985 A1 has become known a device for processing crushed stone, which is equipped with a horizontal hollow rotary drum and a rotor inserted therein eccentric. The rotary drum is arranged slightly inclined to the horizontal. The rotary drive for the rotary drum has a reverse direction of rotation as the rotational drive of the rotor. Due to the eccentric arrangement of the rotor to the rotary drum a reduced gap for mechanical treatment of the crushed rock is provided at one point. Due to the horizontal arrangement of the rotary drum, the device requires in the DE 2 812 985 A1 a considerable amount of space, since only a small degree of filling is achievable.

With the DE 2 212 251 C3 a device for crushing contained in raw gravel lumpy foreign matter such as loam or the like has become known, wherein a vertically erected fixed tubular container is provided in which on a rotatable shaft, an agitator is arranged, which stirs the material present in the vertical container to be processed material. The device according to the DE 2 212 251 C3 has a smaller footprint, but also has limited throughput. The intensity of the energy input is due to the geometry of the agitator only very low, since only a few particles are directly in contact with the agitator.

It is therefore the object of the present invention to provide an apparatus and a method for the preparation of materials, which with a small space requirement, a high throughput is possible.

This object is achieved by a cleaning device having the features of claim 1 and by a method having the features of claim 15. Preferred developments of the invention are defined in the subclaims. Further advantages and features will become apparent from the general description and the description of the embodiment.

An inventive cleaning device is used for processing of materials. In particular, the cleaning device is for processing materials comprising granular mined material. The cleaning apparatus for processing materials may also be provided for crushing lumpy impurities contained in raw gravel such as loam or the like. The cleaning device according to the invention has an upright tubular container. An axis device is arranged essentially centrally in the tubular container. Between the axle device and the inner wall of the tubular Container is provided a process space for receiving the material to be processed. In this case, the tubular container is driven in rotation. In the process room drivers are provided as working bodies.

The cleaning device according to the invention has many advantages. A significant advantage of the cleaning device according to the invention is that in an upright arrangement of the tubular container, the container is driven in rotation. In this case, the axle device may be provided fixed. The relative movement between the dogs in the process space and the process space or the tubular container or the axis device is caused by the rotational movement of the tubular container.

Surprisingly, it has been shown that, in contrast to a rotating central axis, a driven rotating outer wall has a significantly higher entrainment effect on the introduced material and thus a better flow through and thus an increased cleaning effect can be achieved. Preferably, at least one working member is provided on the tubular container.

In a preferred embodiment, at least one working member is arranged interchangeably on the tubular container. Such a development is very advantageous because it allows easier maintenance and easier adjustment of different properties in the processing of materials. By replacing a working body, for example, in the case of wear, the operation can be continued without much effort. It is not necessary to first empty the material present in the process space in order to exchange the external working organs.

Preferably, at least one working member is interchangeably arranged on the axle device. An embodiment in which Both working organs are arranged on the tubular container and on the axle device, allows a particularly effective treatment and cleaning of the material to be processed. This is especially true when the working organs or at least two working organs process direction and / or overlap in the vertical direction. This is to be understood here as meaning that at least two working members overlap at least temporarily in the vertical direction during operation. In other words, the working areas of at least two working members overlap at least partially in the vertical direction.

Preferably, an adjustable or variable working gap is provided between the inner wall of the tubular container and an outer wall of the axle device. An adjustable working gap leads to the fact that the working speed of the cleaning device can be influenced. A larger working gap results in greater throughput, while a smaller working gap reduces throughput but increases intensity. Depending on the material to be processed, a corresponding working gap may be ideal, which can be adapted in this way.

In particular, it is possible that the working gap over the height of the tubular container is provided stepwise or continuously adjustable. This allows several different working gaps above the height of the tubular container. As a result, for example, the residence time can be increased in a first height section.

Preferably, the axle device has a non-circular axis and arranged around substantially spaced spacers. The non-circular axis may be polygonal or have a star-shaped, egg-shaped, oval, Torx-shaped cross-section or the like.

Preferably, spacers of different diameters are provided to provide different working gaps. Spacers with defined - same or different - lengths can be strung together on the axis. By juxtaposing spacers of different diameters, different working gaps are formed above the height. With the number of identical or different spacers, the number of working organs can be varied.

Preferably, at least one working member is designed as an inner working member which projects from the inside into the process space. Such an inner working member may be formed attachable in particular to the axle. Preferably, the inner working member is alignable at different angles to the axis.

It is possible that the inner working member or the internally arranged working member has one, two, three, four or more drivers. In the case of a plurality of drivers, the drivers are in particular distributed substantially symmetrically over the circumference of the working member. If a working member has, for example, three drivers, these preferably extend after mounting on the axle in each case at an angle of 120 ° to one another.

Preferably, at least one internally arranged working member is provided on the axis between at least two spacers. It is also possible that two or more spacers are directly adjacent. It is also possible that, instead of a working member, a similarly designed unit is provided which has no catch and does not act on the process space. Then, optionally, instead of a working member, such a unit can be placed between two spacers. In a simplest case, such a unit consists of a circular disk, which is on the axis is plugged.

Preferably, at least one working member is designed as an outer working member or as an externally arranged working member, which projects from the outside into the process space. In particular, the outer working member is introduced from outside through the wall of the tubular container into the process space. Such a configuration is particularly advantageous, since a very simple exchange of external Arbeitsorgangen is possible. A working member can be removed through the wall of the tubular container to the outside, and it can be a similar or another working organ to be reintroduced from the outside through the wall in the process room.

The insertion for the introduction of a working member can be closed, for example via a suitable closure member when no working member is needed at the insertion.

In this way it is possible to provide on the outer circumference of the tubular container a plurality of insertion openings, of which - as needed - only a smaller or larger proportion is used to hold work organs.

This allows a particularly flexible construction, in which the number and type of acting work organs can be adjusted as needed.

Accordingly, different working organs can be provided with carriers of different lengths and / or shape. It can be provided with drivers different length and / or shape both internally arranged work organs as well as externally arranged work organs.

Preferably, in the outer or externally arranged work organs these are secured by at least one bolt part.

Such a fuse can prevent unintentional pulling out or pushing out and can optionally serve as a torque arm during operation.

It is also possible that individual, several or all working organs can be equipped with drivers, which result in different angles to the longitudinal axis of the driver. For example, a driver may be formed as an elongated approximately sword-shaped rod whose sword surface is aligned in a vertical plane or inclined to the vertical plane. By tilting in one or the other direction, the material to be processed can be directed axially in the direction of the exit or in the direction of the entrance by the interaction with the corresponding driver in order to reduce or enlarge the processing period.

In preferred developments, the tubular container has a wear protection device on the inner wall. The wear protection device may in particular be designed as autogenous wear protection and in particular at least partially comprise circumferential webs and preferably extending transversely thereto longitudinal struts.

Such a wear protection device causes accumulating in the formed between the webs and longitudinal struts pockets aufzubereitendes material, which reliably protects the wall of the tubular container from abrasion. The frictional stress is then not directly on the inner surface of the tubular container, but there is a frictional stress within the material to be processed, whereby an effective extension of the service life is made possible.

Preferably, the tubular container is supported in at least one region at the upper and / or lower end. Of the tubular containers may also be stored in areas of the upper and lower ends. In this case, the tubular container can be mounted exactly at the upper and / or lower ends. But it is also possible that the storage is spaced from the upper and lower ends. Possible and preferred storage is only up and down and especially only below.

Preferably, at least one control device is provided with which, in particular, the rotational speed of the tubular container can be controlled.

For driving the rotatable tubular container, in particular at least one motor is provided, which drives the tubular container, for example via a belt drive or a transmission. As a motor, in particular a gearless direct drive, such as in particular a torque motor can be provided. Other drives are possible.

It is possible for at least one fill level sensor to be provided in order to enable control of the preparation as a function of the fill level in the process space or the tubular container.

In advantageous developments, at least one upper filling opening for the supply of material and at least one lower discharge opening for the removal of material are provided. The upper filling opening is associated in particular with a conveyor belt or a hopper, and the lower discharge opening is preferably arranged downstream of at least one take-off element, which is taken from a group of withdrawal organs comprising belt conveyors, chain scraper conveyors, rotary valves and vibratory conveyors.

The degree of filling in operation is preferably on average greater than 0.4 and in particular greater than 0.6 and preferably greater than 0.7 and more preferably greater than 0.8. Even values of 0.9 and larger are possible. Preferably, the degree of filling is determined by the level sensor and controlled by the control device.

The axle device may be stationary. But it is also possible that the axle device is rotatable. If the axle device is designed to be rotatable, it is in particular provided rotatable in opposite directions to the tubular container.

The inventive method is used for processing of materials, such as granular material mined from deposits and / or crushing contained in the raw gravel lumpy foreign matter such as loam or the like and is carried out with a cleaning device, which in the cleaning device upright tubular container and a substantially having centrally disposed in the tubular container axis means. Between the axis device and the inner wall of the tubular container, a process space for receiving the material to be processed is clamped. The tubular container is driven in rotation and in the process space drivers are provided as working organs.

The method according to the invention is also very advantageous since it enables effective processing and preparation of materials.

For the purposes of the present invention, an uprightly arranged tubular container is understood in particular to mean a substantially vertically arranged tubular container. It is possible that the tubular container is aligned exactly vertically. But it is also possible that the tubular container and / or its axis of rotation are arranged inclined to the vertical by a slight angular amount. For example, angles of 2 °, 5 °, 10 °, 15 ° or even 20 ° possible. In any case, the angle of inclination is less than 30 ° and preferably less than 10 °.

Further advantages of the present invention will become apparent from the embodiment, which will be explained below with reference to the accompanying figures.

With reference to the accompanying figures, an embodiment of the system 100 according to the invention is described below, which comprises a cleaning device 1 according to the invention.

Fig. 1 shows a highly schematic side view of a plant 100 according to the invention, which here comprises a cleaning device 1 and a downstream screening machine 120.

The plant 100 is used for processing materials such. As materials comprising degraded granular material from deposits and / or for processing and in particular for crushing contained in raw gravel, lumpy foreign matter such as loam or the like. The plant 100 according to the invention is also suitable for processing other similar materials.

This in FIG. 1 schematically illustrated cleaning device 1 comprises a tubular container 2 and an axis means provided therein 3. While the axle device 3 is preferably arranged here fixed, the tubular container 2 is rotatably mounted.

Between the inner wall 4 of the tubular container 2 and the outer wall 11 of the axle device 3, a process chamber 5 is clamped, which is substantially completely filled with material 6 to be treated during operation, which is supplied to the cleaning device 1 from above via the upper insertion opening 34.

The material 6 to be processed can already be pretreated or pre-classified, for example in an upstream cleaning device.

The processed material emerging from the process chamber 5 at the lower end 30 is transported away via a take-off element 36, such as a belt conveyor.

In the illustrated embodiment, the discharged through the lower discharge opening 35 material 6 of a screening machine 120 of the processing plant 100 is supplied. At the screening machine 120, for example, water can be supplied as a liquid to to support the preparation. On the screening machine 120, the material to be treated is preferably separated into at least two fractions, which can subsequently be subjected to further treatment steps.

The tubular container 2 of the cleaning device 1 can be driven by an electric motor 32. For power transmission from the motor 32 to the tubular container 2 may serve a drive belt. It is also possible to use a transmission which consists of two or more gears or the like.

The rotation of the tubular container 2 is controlled by a control device 31, which can preferably also serve for process monitoring.

For monitoring the filling wheel 37, at least one fill level sensor 33 can be provided, which detects, for example optically, electrically or magnetically, a measure of the degree of filling 37. It is also possible that a weight sensor is used, for example, detects the weight of the tubular container 2 and the entire cleaning device 1 and derived therefrom a parameter for the degree of filling 37. With known density of the material to be processed and / or presentation of empirical data can be reliably deduced on the weight of the cleaning device to the degree of filling 37.

Depending on the degree of filling and / or empirical values and / or, for example, the electrical power consumption of the motor 32 and / or the current speed of the tubular container 2 can be deduced on the operating conditions and, accordingly, the speed of the tubular container 2 can be increased or decreased or, for example Amount of material supplied above 6 increased or decreased to obtain the desired operating point or observed.

It is also possible to control the process via the number and type of working members 9, 10 or the diameter of the spacers 15, 16.

On the axle device 3 working members 9 are arranged. The working members 9 are referred to here as inner or internally arranged working members 19, since they protrude from the inside into the process space 5. The number, type and orientation of the working members 9, which may include different numbers of dogs 7, is variable and can be selected as needed.

At the tubular container 2 working members 10 are provided with carriers 8. The working members 10 may be referred to as outer or externally arranged working members 20, since the driver 8 protrude from the outside into the process space 5.

Here, as shown better in the following figures, the working members 10 are introduced from the outside through the wall 24 of the tubular container 2 in the process chamber 5. In this case, the length, shape and number of drivers 8 may be variable at the work organs 10.

Such a configuration enables a flexible number of working members 10, since, as required, working members 10 can be introduced from outside into the tubular container 2 and thus into the process space 5 through the insertion openings 23. This can optionally take place during a short stop during operation, so that, for example, changing conditions of the material 6 to be processed can be addressed and reacted.

In FIG. 2 is an enlarged cross section through the cleaning device after FIG. 1 displayed. Inside the tubular container 2, the axle device 3 is shown. The axle device 3 consists of a central and here polygonal and preferably square in cross-section axis 14, to the succession spacers 15 or 16 and working members 9 are attached.

The working members 9 each have one or more drivers 7. The drivers 7 extend from the axis 14 to the outside. The orientation of the driver 7 may be radial, but may also have tangential or vertical components.

For the necessary distance in the process direction or vertical direction 38 between two working members 9 provides an interposed spacer 15 or 16. It is also possible that two or more spacers 15 or 16 are attached directly one behind the other.

As FIG. 2 can be clearly seen, the provided in the upper region spacers 15 have a smaller diameter 17 than the provided in the lower region spacers 16, which have a larger outer diameter 18.

As a result, a larger working gap 12 is made possible here in the upper region than in the lower region, where a significantly smaller working gap 13 exists between the outer wall 11 of the axis device 3 and the inner wall 4 of the tubular container 2.

It is also possible for a smaller gap 13 to be provided in a topmost area, followed by a larger gap 12 further down, which in turn is followed by a smaller gap 13 further down.

By spacers 15, 16 with two or more different outer diameters 17, 18, the process space so be designed as it is optimal for the respective material to be processed 6. In this case, the structure can be changed flexibly, since the individual components are pushed onto the non-circular axis 14 from the outer cross section here. The spacers 15, 16 in turn provide a round outer cross-section, so that the wear is reduced. In addition, the axis 14 is protected from contamination to allow easy change of the working members 9.

A water supply 44 can be provided, which can be switched on as needed to influence the cleaning process.

FIG. 3 shows a further schematic cross section through the cleaning device 1 and through the tubular container 2 and the axle device 3. At the axle device 3 here each identical spacers 15 are provided, which all have the same outer diameter. The working elements 9 mounted on the axle device 3 are angularly different from the axis 14 in order to ensure a correspondingly homogeneous mixing of the process space 5.

On the outer surface of the tubular container 2, a plurality of insertion openings 23 are provided, which are distributed symmetrically about the circumference and arranged in several different heights. The insertion openings 23 allow a flexible number of inserted working members 10. The drivers 8 of the inserted from the outside working members 10 protrude into the interior of the process chamber 5 inside. Here, the working members 9 and 10 and their drivers 7 and 8 in the vertical direction 38 are formed and arranged so that the working areas of the drivers 7 and 8 at least partially overlap. This ensures a special: good mixing of the process area. A simple assembly and disassembly is still possible because during disassembly first the outer work organs 10 can be removed before the Axle device 3 in total or the spacers 15, 16 and the working members 9 can be removed.

To secure the outer working members 20 to the tubular container 2 and to support the same bolt members 25 are provided, which can be introduced depending on the orientation in one of the two openings 39 of the working members 10.

Additionally is in FIG. 3 to detect a wear protection device 26. The wear protection device 26 here comprises vertically arranged longitudinal struts 28, which are arranged distributed on the inner circumference of the tubular container 2 and horizontally arranged webs 27, which are arranged at periodic intervals above the height of the tubular container 2.

Here, each double webs 27 are provided, between each of which the insertion openings 23 are provided for insertion of the working members 10. As a result, the tubular container 2 is additionally reinforced at the insertion openings 23 in order to absorb the load. Furthermore, the wear protection device 26 also serves to protect the inner wall 4 of the tubular container 2 from wear. In the recesses between the webs 27 and the longitudinal struts 28 to be processed material 6 will accumulate during operation, which thus serves as autogenous wear protection. As a result, the frictional stress no longer takes place on the inner surface of the inner wall 4, but within the material to be processed. In addition, the webs 27 and struts 28 can support the working members 10 with a suitable arrangement.

FIG. 4 shows a highly schematic plan view of a tubular container 2, wherein through the wall 24 of the tubular container 2 here a total of four working members 10 are pushed through with their drivers 8. The working members 10 are each offset here at an angle of 90 degrees.

On the axle device 3, two working members 9 can be seen here, which extend from the inside into the process space 5. Both working members 9 here each have a driver 7, which differ in their effective length.

In all embodiments, it is possible to use different working organs 9, 10. The FIGS. 5 to 7 show three different variants of working organs 9.

FIG. 5 shows a working member 9 with a single driver. 7 FIG. 6 shows a working member 9 with two opposite drivers 7a and 7b. FIG. 7 represents a working member 9 with three drivers 7a, 7b and 7c, which are each provided at an angle of 120 degrees offset from one another.

The inner circumference of the working members 9 is adapted to the outer circumference of the axis 14, that the working members 9 can be arranged on the one hand rotationally fixed on the axis 14 and on the other hand possible to position each other at different angles. Exemplary are in FIG. 6 two different angular positions 21 and 22 to an axis 14 schematically drawn.

FIG. 8 shows two different embodiments of a working member 10, wherein the drivers 8 are configured differently long. Plotted drawn a length 43 of the entire working body, while dashed another variant of a working member 10 is shown with a shorter length 42. The working members 10 are introduced through an insertion opening 23 in the process chamber 5, so that the driver 8 protrudes into the process space 5. On the other hand, the openings 39 remain outside of the tubular container 2. There, the working member 10 can be secured to the cleaning device 1 via a bolt part 25, which is inserted into one of the openings 39.

If no working member 10 is needed at one position, a closure member 40 may be used instead, which does not or substantially not dive into the process space 5.

FIG. 10 finally shows a perspective view of the cleaning device 1. At the upper end of the hopper 41 can be seen. Therein, the axle device 3 can be seen with the fixed here axis 14, which here has a square cross-section. On the outside of the tubular container 2, the inserted working members 10 are shown, which are inserted into insertion openings 23. It is also possible here to insert not only working members 10, but also closure members 40, which need not necessarily be distinguished from working members 10 from the outside. However, it is preferred that the closure members 40 differ, for example, in color or in structural features, so that it can be recognized at first glance whether a working member 10 or a closure member 40 is inserted at a position.

Overall, the invention provides a highly compact cleaning device 1 available, which can be operated with a high degree of filling 37 of greater than 75% and in particular greater than 90%, thus ensuring a high throughput with low space requirements.

Because the working members 9 and 10 can be flexibly inserted and replaced, an optimum operating point can be found for almost every material to be reprocessed. Due to the flexible adjustment of the working gap 12 or 13, which can be varied even within the implement 1, the throughput can be limited in a simple manner, for example, if the gap is tapered downwards.

In addition, the cleaning device 1 according to the invention allows easier maintenance, since in particular the inserted from the outside Work modules can be replaced even without a short stop without emptying the container 2.

The fact that the tubular container is rotated, an energy-saving and little space-requiring and effective treatment can take place. Due to the rotating outer wall, the stress intensity within the process space 5 is considerably higher than in the prior art. The introduced energy density is larger, allowing a more effective deagglomeration. The shear gradient acts on the entire rotating surface, which is greater than if only individual stirring arms are moved. Overall, an efficient and intensive selective comminution of the adhering foreign substances of the discontinued material is effected. <B> LIST OF REFERENCES: </ b> 1 cleaner 23 insertion 2 tubular container 24 wall 3 axis unit 25 bolt part 4 inner wall 26 wear protection 5 process space 27 web 6 material 28 longitudinal strut 7 Driver 29 top end 7a Driver 30 lower end 7b Driver 31 control device 7c Driver 32 engine 8th Driver (outside) 33 level sensor 9 Working organ 34 fill opening 10 Working organ (outside) 35 discharge opening 11 outer wall 36 off element 12 working gap 37 fill factor 13 working gap 38 vertical direction 14 axis 39 Hole (for 25) 15 spacer 40 tuck 16 spacer 41 hopper 17 diameter 42 length 18 diameter 43 length 19 internal working organ 44 water supply 20 external working organ 100 investment 21 angle 120 screening machine 22 angle
