Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of Application The invention advantageously provides a kneading machine with mutually adjacent kneading chambers, each of which can be driven, in particular at different rotational speeds. It has two axes-parallel, for example oppositely oriented, kneading tools, the kneading chambers communicating with each other by an opening passing transversely to the axis of the kneading tools, and a first kneading chamber. The kneading chamber has a charging inlet, the last kneading chamber has an outlet, and two or more kneading chambers are arranged in a row.

Prior Art A kneading machine of the type described above is disclosed in Patent No. 351 of the Federal Republic of Germany.
It is known from specification No. 9349 and has a good reputation.

This is especially the case when materials and substances that are continuously consistent are kneaded and discharged.

However, if the kneading operation is interrupted or the product to be kneaded is replaced, cleaning of the kneading tool and the kneading chamber becomes necessary, at least when desired, or often unconditionally.

Therefore, in known kneading machines, the bearing cover is eventually released on one bearing support side of the kneading tool, and this bearing support is removed.

The kneading tool is then withdrawn from the kneading chamber in the axial direction of the kneading tool shaft or drive shaft, so that it can then be cleaned. The kneading chamber is further cleaned through the opening thus created.

However, this form of work is significantly costly and
The screws and fittings must be removed to move the kneading tool away from its bearing and then reinstalled.
The manual dexterity of the workers performing such work is extremely required. Furthermore, this is considerably time consuming since the kneading tools have to be assembled to each other in the correct relationship and position so that they are in the correct position to move in opposite directions and possibly do not collide with each other. Moreover, in such an assembly operation, care must be taken not only for the fitting portion but also for the seal ring so that the kneading machine does not become airtight during the cleaning process.

In addition, the kneading tool is placed on both sides of the kneading tool shaft.
Each shaft bearing bearing means a wall penetration,
The disadvantage therefore is that the wall penetrations have to be correspondingly rolled. This is because, if not sealed, additional risks arise, especially when compounding explosive products. In particular, the seals provided on the releasable cover are dangerous as they can become damaged during frequent assembly and disassembly.

Problem to be Solved by the Invention An object of the present invention is to provide the above-mentioned method in which it is easy to access the kneading tool and the inside of the kneading chamber for returning to the army, or the cost and time required to do so are reduced. Our objective is to provide a kneading machine for this purpose.

Means for Solving the Problem The measures taken to solve the above-mentioned problem are that the kneading tool is mounted on one side or in a floating manner, and that the casing or casings of the kneading chamber are mounted on the shaft of the kneading tool. The kneading tool has a separating point which extends in a transverse direction, and furthermore, the part of the casing at the separating point on the side opposite to the bearing bearing device is movable in a direction away from each other. be.

Function: In order to clean the kneading tool and the kneading chamber, only the separated part of the casing is opened and the casing part move them away from each other. Thereby, it is no longer necessary to separate the dynamic sealing and bearing points of the drive shaft or the shaft of the kneading tool, so that damage can no longer occur at these points. Even at the separation points, only statically loaded seals are required.

Effects of the Invention The advantage obtained by the invention is that the penetration or inlet for the kneading tool shaft or drive shaft is made in one wall of the kneading chamber, so that it is possible to reduce the pressure in some cases compared to the bearings on both sides. Overall, even expensive floating bearing bearings can be profitable. In particular, no airtightness occurs in walls that now no longer have shaft penetrations.

According to an advantageous embodiment of the invention, the housing part of the kneading tool facing away from the bearing support and the housing part with or near the bearing support are releasably connected; Furthermore, at least one housing part is movable in a direction away from the other housing part. The bearing bearing arrangement in one of the casing parts therefore remains uncontacted and unchanged upon separation and opening of the casing.

By arranging the separation points of the housing or of the kneading chamber in a plane extending at right angles to the kneading tool axis, a structurally simple and operationally advantageous configuration is obtained.

The separating movement takes place approximately in the direction of alignment of the tool axis, and the risk of a collision of the kneading tool with the inner wall of the casing part during the separating movement and later on the joining is therefore reduced if the kneading tool does not conform to the inner contour of the kneading chamber. Even the case of almost complete filling is almost eliminated.

Disassembly, which is advantageous both for separation, for bonding and for cleaning, is such that the separation point is located in the closing wall of the casing, along the edge of said closing wall, which is penetrated by the drive shaft of the kneading tool. Obtained by extending. This allows a large part of the casing and a large part of the wall of the casing to be moved away from the other casing part, and both casing parts to be accessible for cleaning and yet to be separated from each other. However, it may be possible to have as few protrusions and wall connections as possible which have to be taken into account during cleaning.

As already mentioned, by separating the kneading chambers according to the invention, only statically loaded seals are required. In this case, at least one sealing element is arranged on the contact surface or surfaces of the casing parts with the separating point, in particular inserted into a retaining groove or the like of one of the casing parts to be separated. It is advantageous. When joining the two housing parts, such a seal contacts automatically and under pressure, so that the seal reaches its point of use without difficulty.

A significant advantage of the floating bearing mounting of the kneading tool is that the kneading machine, on the wall opposite to the floating bearing mounting, has a temperature regulating device or can be connected to the temperature regulating device. It lies in being able to configure it in a certain way. moreover,
Such a configuration is special since such a wall no longer needs to be used to receive a separate bearing of the kneading tool.
It is advantageous for In short, based on such a configuration,
A large amount of thermal energy can be supplied to the materials being kneaded while supplying heat.

An analogy also applies in some cases for cooling.

Furthermore, the disassembly and separation of the casing of the kneading chamber takes place mechanically and, in particular, by remote control, which significantly reduces operating costs and reduces downtime for cleaning.

In order to make the assembly and disassembly during separation of the mixing chamber casing as simple as possible and to ensure that the aforementioned mechanical separation can be carried out as accurately as possible, the movable casing part of the mixing chamber is supported on guides or guide rails. It is advantageous if a fitting device, for example a fitting surface or a fitting pin, is also arranged in the region of the separation point. In this case, the guide ensures that, when joining the casing parts, the mating device located in the region of the separation point is applied reliably, so that a coordinated closing of the kneading chamber after cleaning occurs problem-free and quickly. That is guaranteed.

For opening and closing the kneading chamber and for separating the casing parts, an actuating cylinder, in particular a hydraulic actuating cylinder, is provided.

In order to avoid soiling the area around the mixing chamber during separation, especially the underside of the separation point, at least one collection trough is provided below the separation point or under the movement path of the movable casing part. (It is being pulled.

Such a collection trough also collects the separating and cleaning elements and the residues removed from the kneading chamber and kneading tools during the final cleaning process and is therefore shielded by this collection trough. The guide is protected from this residue. moreover,
It is advantageous if a guide or guide rail for the movable casing part of the kneading chamber extends below the kneading chamber, and the collecting trough is arranged between the kneading chamber and the guide, in particular in a removable manner. It is. If the collection trough is removable, the collection trough itself can be easily emptied after the retrace process.

If the movable housing part of the kneading chamber is clamped in the closed position by a stationary housing part, especially hydraulically, assembly costs during the cleaning process can be further reduced. In this case, the closing position does not have to be fixed by a constant screw, which each time opens for separation and screws again for connection.

In order to keep the mass displaced during separation as small as possible, and thus also to reduce the outlay on the mechanical devices for this displacement or movement, the kneading tool is mounted on the side opposite the bearing arrangement of the kneading tool. It is particularly advantageous if the housing part of the Japanese-style chamber is a movable housing part and is furthermore movable in the axial direction of the drive shaft of the kneading tool in the direction away from the kneading tool or can be pivoted.

The ability to separate the kneading chamber of a kneading machine as in the present invention makes it particularly useful when kneading products that may cause a sudden increase in pressure within the kneading chamber, such as explosive substances. Allows you to configure. In other words,
The movable casing part is fixed in the closed position by means of a stop on the transmission casing or a similar stationary part of the bearing arrangement of the kneading tool, or in particular is hydraulically tensioned and further kneaded. The closing wall of the kneading chamber, which is pierced by the drive shaft of the kneading tool, is pressed in the axial direction optionally with a return force to the sealing surface of the adjustable casing part of the kneading chamber. This ensures that, in the event of a sudden overpressure in the kneading chamber, the walls are displaced against the return force, that is to say against the force of the spring which is advantageously pressed by the walls, and the caning explodes or ruptures. The overpressure can be extinguished immediately before it occurs. In short, the casing wall, which is stationary per se, can also be adjusted upon opening of the kneading chamber, in particular against an adjusting movement of the movable casing part, and of course only in this case against a significant return force of a significant overpressure. Adjustable.

Furthermore, the stationary casing part can be deflected by a predetermined displacement distance from the interior of the kneading chamber when the kneading chamber is closed.

In this case, in particular, a closing wall with a penetration for the drive shaft of the kneading tool is pressed against the sealing surface of the separation point by spring force, and furthermore in the axial direction of the drive shaft away from the separation point. It is possible to exercise. It is furthermore advantageous if the bearing arrangement of the shaft of the kneading tool is provided not only in the closing wall, but also in the stationary part of the bearing arrangement or in the transmission casing, which is used as a collar for the movable casing part. It is provided in

Alternatively or additionally as an overpressure safety device,
The kneading chamber has a second separation point, in particular the wall of the movable housing part opposite the wall is separated with respect to said wall and is provided with a return force, preferably a spring. The second separation point is crimped by force. As a result, the bearing-free wall of the movable casing part can be used as an overpressure safety device, since the kneading tool is mounted floatingly, that is, on one side. It is advantageous that such a wall does not have a bearing arrangement and does not have a through-hole with a corresponding sealing element.

Overall, cleaning is significantly easier and faster;
Furthermore, a kneading machine is obtained which can be used as a continuous kneading machine if the last kneading chamber is equipped with a discharge screw conveyor, for example a l-shaft or two-shaft screw conveyor. Furthermore, an overpressure safety device can also be installed in the kneading chamber in a simple manner on the basis of the floating bearing arrangement of the kneading tool.

In order to also be able to clean the drive shaft of the kneading tool in the area of the through-opening in the kneading chamber, a further development of the invention provides for the movable casing part as well as the kneading tool to open the kneading chamber. The casing wall with the penetration of the drive shaft is adjustable or movable in mutually opposite directions away from the kneading machine, and the drive shaft also has a return thread in the area of the penetration; This is because the drive shaft can be advantageously accessed after opening the kneading chamber for cleaning. Furthermore, the closed position of the casing relative to the movable casing part can be determined by a spring force, in particular a compression spring, which spring force can be overcome by the working cylinder when the kneading chamber is opened.

Example #II! The kneading machine 1 shown schematically in FIG. Two kneading tools 3 are engaged which are parallel to each other and can be driven at mutually different rotational speeds as the case may be. Furthermore, the kneading chambers 2 are arranged next to each other in horizontal rows and are connected to each other by openings 5 which are penetrable at right angles to the axis or drive shaft 4 of the kneading tool 3, so that the kneading material From the first kneading chamber 2, which has a charging port 6 and a charging hopper 7, the material can reach the next kneading chamber 2 and be further processed.

The last kneading chamber is provided with a discharge opening 8 and, if necessary, a discharge screw 9 or similar auxiliary means for discharging the kneaded material.

As can be seen from Figures 1, 83 and 4, the kneading tool 3
are mounted on one side, that is, floatingly in roller bearings 10 of the transmission housing 11, said roller bearings IO respectively at the ends of this transmission housing 11! ! It is located at 12.

Figure 1, Figure 3 and! As shown in FIG. 4, one drive shaft 4 of the kneading tool 3 has a gear 13 with a small diameter.
A parallel drive shaft 4 of a kneading tool 3 operating in the same kneading chamber 2
have a large gear 14, which allows mutually different rotational speeds of the kneading tool 3 within one common kneading chamber 2. Furthermore, as is clear from Fig. 2, the cross-sectional shape of the kneading chamber is formed by two circles that intersect in the overlapping range of the kneading tool 3, and in short, it is very precisely adapted to the envelope circle of the kneading tool. There is. Correspondingly, the individual kneading chambers 2 are small and the cleaning of the kneading chambers and of the kneading tools appears to be correspondingly difficult.However, according to the invention, the kneading tools 3 and the kneading chambers to the inside of 2,
In particular for good access to cleaning or repair vessels, the kneading tool 3 is, as already mentioned, mounted in a floating manner;
The casing 15 of the kneading chamber 2 has a separation point 16 extending at right angles to the axis of the kneading tool, the kneading chamber being provided with a casing part 17 opposite the roller bearing 10 at this separation point 16 of the bearing arrangement. and the kneading tool 3 are movable apart from each other by means of their bearings, which means that in the exemplary embodiment the casing part 17 can be moved from the position shown in solid lines to the position shown in broken lines. This is achieved by being However, the part with the kneading tool 3 can also be moved in the opposite direction for separation.

Furthermore, as can be seen from Fig. 1, the roller bearing 1 of the kneading tool 3
The housing part 17 opposite 0 and the housing part 8 near the bearing are releasably connected, and at least one housing part can be moved apart from the other housing part. In this case, in Figure 1,
The movable song part is indicated by 17 and is the casing part.

As shown in FIGS. 3 and 4, for opening the kneading chamber 2, the movable casing part 17 also has a penetration 19 for the drive shaft 4 of the kneading tool 3, here the casing The casing parts 18 forming the walls are also adjustable or movable away from the kneading tool 3 in opposite directions, as will be explained in more detail below.

This results in J of the 40th order of the drive shaft.

Such points, i.e., located in the area of the penetration 19 of the connecting part 18 in the position of use, may have, for example, a return thread, which may have to be cleaned from time to time in order to improve the sealing properties. You can also get close to the place.

As already mentioned in FIG. 1, the casing part 917 of the kneading chamber 2 opposite to the roller bearing of the kneading tool 3 is a movable casing part, and the drive shaft 4 of the kneading tool 3 is movable. By being movable away from this kneading tool in a direction or possibly pivoting away in some suitable manner, both in the kneading tool 3 itself and inside the kneading chamber 2. Good access for cleaning. However, the aforementioned additional movement of the woosing portion 18, as shown in FIGS. 3 and 4, improves the cleaning possibilities in certain ways. This also applies to the wall 4 shown in FIG.
This is because the area provided with the return screw thread 20 can be accessed well.

Moreover, in both cases the separation point 16 extends in a plane running at right angles to the kneading tool axis and thus in the axial direction of the housing part 17 and/or the housing part 18 which is formed as a closing wall on the bearing side. Movement leads to correspondingly simple separation.

Furthermore, the kneading tool 3 has a separation point 16 in the casing 15.
In the closing wall (casing part 18) pierced by the drive shaft 4 of , extending along the edge of this closing wall:
This is particularly advantageous both for accessibility during cleaning and for simplifying the construction of the separation point. This ensures that after separation the user can completely remove the almost generally smooth inside of the closed M wall on one side and from the side wall on the other side; clean the casing part 17 in front and both well. can do.

As can be seen from FIGS. 3 and 4, a sealing member 2 is provided on the contact surface of the casing parts 17 and 18 with the separation point 16.
1 is arranged and placed in a holding groove of one of the housing parts to be separated, in the exemplary embodiment a gauging part 18 which serves as a closing wall. Since the kneading tool 3 and its drive shaft 4 are floatingly mounted, only one wall, in the exemplary embodiment the closing wall, is provided with a penetration 19 and a corresponding dynamic sealing element, whereas Thus, the oppositely located wall 22 has no movement, even if this wall 22 is not removably attached to the casing part 17 and can be sealed by a static seal member 23. No physically loaded sealing members are required.

Said wall 22 opposite the floating bearing bearing device has a temperature regulating device in a simple manner on the basis of the fact that it does not have any bearing gap and no cover, or can be equipped with a temperature regulating device. The possibility of heating or cooling the kneading material into the kneading chamber 2 by means of a connectable and therefore floating bearing arrangement is created.

As can be seen from FIGS. 3 and 4, the disassembly and separation of the casing 15 of the kneading chamber 2 is carried out mechanically and also remotely controlled by the actuating cylinder 24. In this case, the movable casing part 17 moves along the guide.
In other words, in the embodiment, the guide rail 2 is circular in cross section.
5 and also has a mating surface or mating pin in the area of the separation point 16, which allows for precise and precise joining of the movable housing parts 17 and 18. The original position will be automatically restored again.

Opening, closing and cleaning section 17.1 of kneading chamber 2
The working cylinder 24 used for the separation of 8 is preferably a hydraulic working cylinder, the piston rod 26 (FIGS. 3, 4) of this working cylinder being preferably fitted with a piston rod. A folding bellows 27 is arranged to protect and cover 26.

As shown in FIG. 2, at least one collecting trough 28 is provided below the separation point 16 and below the travel path of the movable casing part, which collects the products that fall when opened. Collects residue and contaminants that fall during cleaning,
In addition, the guide rail 25 is prevented from being damaged by these objects.

In this case, the guide rail 25 for the movable casing part 17 of the kneading chamber 2 is connected to the kneading chamber 2 and the casing 15.
A running and collecting trough 28 which may alternatively be located below, for example laterally or even entirely above the
is particularly removably arranged between the kneading chamber 2 and the guide, so that this collecting trough 28 itself can be emptied or cleaned easily.

In the closed position of the kneading chamber 2, the movable casing part 17
can be constant by being in particular hydraulically tensioned in the closed position with a fixed casing part 18, which, as already mentioned, may itself be movable; The tensioning with 18 can be realized in a simple manner in that the actuating cylinder 24 has a dual action. Additionally, in the embodiment according to FIGS. 3 and 4, the housing part 18 is subjected to a pressing force by a compression spring 29, which compresses the shoulder 30 of the push port 31 for the housing part 18. and a casing wall 32, which may be a continuous part of the transmission casing 11. Further, in parallel to this push port 31, a fitting pin 33
is provided on an adjustable carriage 34 by means of a push port 31, which engages a dowel pin 33 when the movable casing part 17 is moved together with a stop 36 of this casing part into the closed position shown in FIG. , the stopper 36
7 langes 35 are fitted through their fitting openings.

As can be seen by comparing FIGS. 3 and 4, when the kneading chamber 2 is opened, the carriage 34 is movable away from the movable casing part 17 and thus the casing part 18 and thus the kneading chamber. The wall on the bearing side of the sealing member 21 is moved from the use position to the open position in the direction of arrow Pfl.
to open. At the same time, movable casing part 17 is moved in the direction of arrow Pf2, which is effected by actuating cylinder 24. Since the carriage 34 is also moved in the direction of the arrow Pfl, the compression spring 29 is relaxed in accordance with FIG. It will be done.

In short, in the embodiment according to FIGS. 3 and 4, the through-guiding opening or through-hole 19 of the drive shaft 4 of the kneading tool 3 is
a housing part 18 with a casing part 18 is pressed against the sealing surface of the separation region and separation point 16 by spring force;
It can be seen that it is also movable axially away from the separation point 16.

The axial movement of the casing part 18 is possible against the force of the compression spring 29, which is not fully compressed in the closed position even without adjustment of the carriage 34, so that during kneading there is no pressure in the kneading chamber 2. This device can additionally be used as an overpressure safety device in the event of a sudden pressure increase. This possibility is further improved if the wall 22 of the casing part 17 is axially separable and movable away from the sealing or contact surface of the wall 22 against a return force. A kneading machine 1 with mutually adjacent kneading chambers 2 in which the kneading chambers 2 can be used is equipped with a kneading tool 3 which is floatingly mounted on one side. The casing 15 of the kneading chamber 2 has a separation point 16 extending transversely to the drive shaft 4 of the kneading tool, preferably in a plane running at right angles to the drive shaft 1. It has been placed. For example, in order to have good access to the inside of the kneading chamber 2 and the kneading tool 3 for cleaning,
The housing part 17 opposite the separation point 16 of the bearing bearing and the kneading tool 3 with this bearing support can be moved away from each other, so that the kneading tool is completely exposed. Additionally, the housing part 18 with the penetration 19 for the drive shaft 4 of the kneading tool can also be moved away from the kneading tool 3, so that the kneading tool 3 and the sealing element 21 in the housing part 18 are also exposed. Therefore, it is movable in the opposite direction to the casing part.
