Device and method

for processing materials

Besehreibung

The present invention relates to an apparatus and a method for processing materials. Especially

The invention relates to a cleaning device and a method for processing materials from reservoirs

contain degraded granular material and / or a

Cleaning device and a method for crushing in

Crude gravel contained, lumpy foreign matter such as loam or the like. 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 DE 2 812 985 AI a device for processing of crushed stone is known, which with a

lying hollow rotary drum and a rotor inserted therein eccentrically. 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. By the eccentric

Arrangement of the rotor to the rotary drum is at one point a reduced gap for mechanical treatment of the

crushed rock provided. Due to the horizontal arrangement of the rotary drum, the device requires a considerable space requirement in DE 2 812 985 A1, since only a low degree of filling can be achieved.

CONFIRMATION COPY With 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 in the vertical container available

stirred material to be processed. The device according to DE 2 212 251 C3 has a smaller footprint, but also has a 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 with the

Features of claim 25. Preferred developments of the invention are defined in the subclaims. Further advantages and features emerge 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 used for

Processing materials comprising granular mined material from reservoirs. The cleaning device for processing materials can also be used for comminuting lumpy impurities contained in raw gravel such as loam or

may be provided. The invention

Cleaning device 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 on the

provided tubular container.

In a preferred embodiment is at least one

Worker replaceable on the tubular container

arranged. Such a development is very advantageous because it simplifies the maintenance and the easier adjustment of different properties in the preparation of

Materials allowed. 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

processing material. This is especially true when the working bodies or at least two working bodies

Process direction and / or overlap in the vertical direction.

By this is meant that at least two

Work organs overlap in operation at least temporarily in the vertical direction. In other words, the overlap

Working areas of at least two working members 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 causes 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, the like

can be adjusted.

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 the juxtaposition of

Spacers of different diameters are formed over the height of different working gaps. With the number of identical or different spacers, the number of working organs can be varied.

Preferably, at least one working organ is internal

Work organ formed, which protrudes from the inside into the process room. 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. Indicates

Working organ, for example, three drivers, they preferably extend after assembly on the axis in each case at an angle of 120 ° to each other.

Preferably, on the axis between at least two

Spacers provided at least one internally arranged working member. 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 driver and not _. acts on the process space. Then, instead of a

Working unit such a unit between two spacers are placed. 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 external

Work organ or designed as 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 on the outer circumference of the

tubular container to provide a plurality of insertion, 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 drivers of different lengths and / or shape. In this case, both internally arranged work organs as well as externally arranged work organs with drivers

be provided different length and / or shape.

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 as

Serve torque arm during operation.

It is also possible that single, several or all

Work organs can be equipped with drivers, resulting in different angles to the longitudinal axis of the driver. For example, a driver may be considered elongated about

be formed sword-shaped rod whose sword surface is aligned in a vertical plane or inclined to the vertical plane. By tilting in one direction or the other, the material to be processed by the interaction with the corresponding driver axially in

Direction of the output or towards the entrance 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 wear protection means that formed in the between the webs and longitudinal struts

Bags processed material accumulates, 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, thereby enabling an effective extension of the service life.

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

Store container exactly at the top and / or bottom 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 is controllable.

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 assigned in particular a conveyor belt or a hopper and the lower discharge opening is preferably arranged downstream of at least one trigger member, which is taken from a group of withdrawal organs, the

Belt conveyor, chain scraper conveyor, rotary valves and vibratory conveyor includes.

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 on the

Control device controlled.

The axle device may be stationary. But it is also possible that the axis device rotatable

is trained. When the axis device rotates

is formed, it is in particular provided in opposite directions rotatable to the tubular container.

The inventive method is used for processing of

Materials such as granular material excavated from deposits and / or crushing of lumpy foreign matter such as loam or the like contained in the raw gravel are carried out with a cleaning apparatus comprising a tubular container erected in the cleaning apparatus and a substantially central one in the tubular container having arranged 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.

Under an upright tubular container is in the context of the present invention, in particular a in

Essentially vertically arranged tubular container understood. 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 inclined to the vertical by a slight angular amount

are arranged. For example, angles of 2 °, 5 °, 10 °, 15 ° or even 20 ° possible. In any case, the inclination angle ^¬ 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. 1 shows a highly schematic side view of a system 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.

The cleaning device 1 shown schematically in Figure 1 comprises a tubular container 2 and a therein

3. While the axle device 3 is preferably arranged fixed here, the

tubular container 2 rotatably mounted.

Between the inner wall 4 of the tubular container 2 and the outer wall 11 of the axle device 3 is a

Spaced process space 5, which is filled in operation substantially at any time almost completely with aufbereitendem material 6, which is supplied from above via the upper insertion opening 34 to the cleaning device 1.

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

The discharged from the process chamber 5 at the lower end 30 recycled material is via a trigger member 36, such as

For example, a belt conveyor, transported away.

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 processed is preferably separated into at least two fractions, which are further connected thereafter

Treatment steps can be subjected.

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 be a

Serve drive belt. Also possible is the use of a transmission, which consists of two or more gears or

the like exists.

The rotation of the tubular container 2 is by a

Controlled control device 31, which may 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. If the density of the material to be processed is known and / or empirical data is available, the weight of the material may be used

Cleaning device reliable on the degree of filling 37

be closed back.

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, the amount of material supplied above 6 increased or decreased to obtain the desired operating point or to comply.

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 from the inside in the

Protrude 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 as needed

to be selected.

At the tubular container 2 working members 10 with

Drivers 8 provided. 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 to be processed 6

can be received and responded.

In Figure 2 is an enlarged cross-section through the.

Cleaning device shown in Figure 1. 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, on the succession spacers 15 or 16 and working members 9 are attached.

The working members 9 have one or more drivers 7 each time. 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 can be clearly seen in FIG. 2, the spacers 15 provided in the upper region have a smaller diameter 17 than the spacers 16 provided in the lower region, 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 between the outer wall 11 of

Axle device 3 and the inner wall 4 of the tubular container 2 is present.

It is also possible that in a supreme area a

smaller gap 13 is provided, to which a larger gap 12 connects further below, which in turn is followed by a smaller gap 13 below.

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. The structure can be flexible

be changed, since the individual components are postponed here on the non-circular axis 14 from the outside cross section. The spacers 15, 16 turn turn a round

External cross-section available, 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 or through the tubular container 2 and the axle device 3. The axle device 3 here identical spacers 15 are provided, all of which 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 are the

Organs 9 and 10 and their drivers 7 and 8 in

vertical direction 38 is 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 for supporting the same bolt parts 25 are provided, depending on the orientation in one of the two

Openings 39 of the working members 10 can be introduced.

In addition, a wear protection device 26 can be seen in FIG. 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.

Figure 4 shows a highly schematic plan view of a tubular container 2, wherein through the wall 24 of the

tubular container 2 here 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 project from the inside into the process space 5

extend. Both working members 9 here each have a driver 7, which differ in their effective length.

In all embodiments it is possible to have different

Working organs 9, 10 use. FIGS. 5 to 7 show three different variants of working members 9.

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

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 possible at different angles

can be positioned to each other. By way of example, two different angular positions 21 and 22 to an axis 14 are shown schematically in Figure 6.

Figure 8 shows two different embodiments of a

Working member 10, wherein the driver 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 inserted through an insertion opening 23 in the process space 5, so that the

Driver 8 protrudes into the process space 5. The openings 39, however, remain outside of the tubular container 2. There, via a bolt part 25, which is inserted into one of the openings 39, the working member 10 on the

Cleaning device 1 are secured. 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.

Finally, FIG. 10 shows a perspective view of the cleaning appliance 1. At the upper end, the filling funnel 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 to insert not only work organs 10 but also closure organs 40, which need not necessarily be distinguished from work organs 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, which makes a more effective

Deagglomeration is possible. 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 adherent

Foreign substances of the discontinued material causes.
