Description

Description: TECHNICAL FIELD The present invention relates to a vertical mixer having a cylindrical container and a removable lid for sealing the upper surface of the container.

The mixer must be thoroughly washed after each change of mixing material, as there is only a small amount of mixing material left, which can significantly change the color or consistency of the next mixing material. This is because the quality may be deteriorated. Often it is difficult to carry out the cleaning work, and this can be time consuming, even after removing the lid.
This is because it is difficult to reach the inside of the mixing container and the stirring tool. Therefore, it is necessary to completely disassemble the stirring tool. In the case of large mixers, it is often necessary to get into the mixing vessel. This task is further complicated by the heating of the vessel and stirrer that were typically intense during the previous mixing process. There is always the risk of leaving the rest of the mixing material behind, as it is difficult to reach the inside of the container.

Therefore, an object of the present invention is to provide a vertical mixer that can be easily and quickly washed.

According to the invention, this object is to tie a lifting device for removing the lid from the container to the lid, the lid being pivotable horizontally based on the lifting device and tiltable about a horizontal axis, Above, the container is bisected in one horizontal plane,
The lower part of the container in contact with the bottom and lifted from the lower part of the container,
The solution is to consist of a double-sided open or a container top that can be swiveled to the side.

Therefore, the lid can be removed from the container and swung to a position vertically adjacent to the container. When placed in this position,
Cleaning the lid becomes easier. The upper part of the suspicion is removable and can be swiveled in the lateral direction or divided into two arc-shaped wall plates, and it is also foldable, so that the inside of the container, the stirring tool, and the container can be easily handled. Arrives. There is no need to disassemble the tool.

The lifting device is tied loosely with the container top so that when operating the lifting device the lid and subsequently the container top are lifted together with the lid. Thus, the lifting device can, for example, be firmly tied to the lid or engage the upper part of the container via a cooperating stopper. Considered as lifting device is a pneumatic cylinder with a vertical lifting mechanism.

The horizontal pivoting movement of the lid to be lifted and / or the tilting movement of this lid is caused by the appropriate drive. Tilting the lid 90 degrees about the horizontal axis 92 eliminates the need for cleaning work from above.

Particularly preferably, two semi-cylindrical wall plates are provided, which are pivotally mounted on a vertical hinge shaft.

It is also possible to prepare an integrated one instead of the upper part of the container that can be opened in a double door. The container is lifted as a whole around a column based on the container part below, pivoted laterally and then rotated again into a horizontal position. This embodiment is easier to manufacture with certain prerequisites as the first embodiment. The vertical seams required for the pattern and the openable container top, which need to be carefully sealed, have been omitted. It is necessary to make the upper part of the container in a simple manner and more accurately in an annular shape.

Furthermore, in the case of this embodiment, a method is also available in which two equally upper container parts that can be used alternately are prepared, one of which is being moved each time, while the other is being washed. It is possible. This can greatly reduce the downtime created for each dose.

In the following, a particularly preferred embodiment of the invention will be described in more detail with reference to the accompanying drawings.

The mixer according to the invention comprises legs 12, 14, 16, 18
It is mounted on a box-shaped pedestal 10 having a. Pedestal 1
Above the 0 is a mixing vessel, which in the following will be referred to as the vessel for short, as well as the prime movers labeled 20, 22. A speedometer 24 is mounted on a casing (not shown) of the prime mover 22, and a ventilator 26 is mounted on the casing wall together with a ventilator prime mover 28. The prime mover 22 rotates a belt wheel 30 lying inside a box-shaped pedestal, which rotates a belt wheel 34 below the container 20 via a V-belt 32. By moving the prime mover 22 with respect to the base 10 using the tightening bolts 36, the V-belt 32 can be tensioned.

A belt wheel 34, also inside the pedestal 10, is mounted on a mixer shaft 38 which penetrates the bottom 40 vertically from below into the container 20. In the pedestal 10, bearings 42 and 44 bear the mixer shaft, and a packing 46 seals the bottom 40.

There is an outlet 48 in the lower part of the side of the container 20. A removable lid 50 is mounted on the container 20. The lid is provided with sealable openings 52, 54, 56 of different sizes and a peep window 58 for filling the mixing material and the admixture (FIG. 2). In addition, referring to FIG. 2, it can be seen that the temperature sensor 60 and the safety thermostat 62 are attached to the outer wall of the container.

The container 20 is mounted on the base 10 via a support structure (not shown).
It is fixed on the top. An agitator (not shown) is also fixed on the mixer shaft 38.

The above-described basic structure of the mixer is not the object of the present invention and will not be a problem in the following description.

A vertical stand pipe 64 stands between the container 20 on the pedestal 10 and the prime mover 22, and the internal space of this stand pipe communicates with the internal space of the pedestal 10 through a hole 66.
In the pedestal 10 below the hole 66, an air cylinder 68 having a piston rod 70 extending vertically through the hole 66.
And a lifting rod 72 extending vertically through the stand pipe 64 is attached to the air cylinder. The lifting rod 72 is firmly connected to the plate 74 at the upper end of the lifting rod projecting from the stand pipe 64, and at the lower end of the lifting rod, it is vertically movably guided at the upper part of the stand pipe 64. At the same time, a collared sleeve 76 guiding the lifting rod 72 is fixed. The lower edge of the collared sleeve 76 has a collar 78 protruding outward.

In the case of the illustrated embodiment, a frame 80 formed of a reinforcing material is mounted on the lid 50, and an exhaust filter 82 is fitted into the frame 80. This filter is lid 5 by a method not shown.
It penetrates through 0 and communicates with the inside of the container 20. further,
A stop 84 is provided on the side of the lid, back-to-back with the prime mover 22, which is rigidly connected to a horizontal shaft (not shown) which is eccentrically located inside a cylindrical casing 86. The casing 86 is also connected to the upper surface of the plate 74 via ribs 88. Horizontal casing 8
A rotary drive 90 is mounted at the outer end located to the right in FIGS. 1 and 2 of 6, which operates to rotate a shaft in casing 86 as described above but not shown. . This geometrical axis is labeled 92.

The sleeve 76 is not only movable in the axial direction at the upper end of the stand pipe 64, but also together with the plate 74, the casing 86, the stopper 84 and the lid 50.
It is also rotatable about its vertical axis.

Therefore, the lid 50 is lifted up from the container 20 through the lifting rod 72, the plate 74, the casing 86 and the stopper 84 by using the force of the air cylinder 68, and by rotating the sleeve 76, it is adjacent to the side of the container 20. After being swung to a suitable position, it is tilted to a vertical posture about the horizontal axis 92 with the help of the rotation driving device 90, and the lid can be sufficiently washed in this posture.

The container 20 is divided into a container lower part 96 and a container upper part 98 based on a horizontal plane 94. The bottom of the container, which ends somewhat higher than the outlet 48, forms with the bottom 40 a cohesive, inseparable unit. This lower part fits tightly and airtightly with the sealing seam 100 with the upper part of the container.

The container upper part 98 captures a cylindrical container part in the closed position shown in FIGS. 1 to 4 2
It is composed of a number of semi-cylindrical wall plates 102, 104.
In this closed position, they are connected to each other by the clamp 106 and to the container lower part 96 by the clamp 108. Supporting arms 110, 112, 114, 116 are attached to the outer surfaces of the wall plates 102, 104, the shape of which can be distinguished from FIGS. 2 and 4, in particular. These support arms 110, 112, 114,
116 is a stand pipe 64 of these lifting devices.
It is expanded like a plate with the sides that are back to back. Within this expanded range, generally labeled 118 in FIG. 2, they receive sleeve portions 120, 122, 124, 126 in vertical gaps not shown, which are shown in FIG. As shown, it encloses the collared sleeve 76 of the lifting device rotatably and axially movable. Therefore, the stand pipe 64 includes the sleeve portions 120, 122, 124, 126, and the support arm 1 fixed to the sleeve portions.
Wall plates 102, 1 along with 10, 112, 114, 116
It forms a hinge / suspension device for 04.

As can be seen in FIG. 1, the sleeve portions 120, 122,
124 and 126 are flush with each other in the closed position of the container, and also the sleeve portion 122 located below.
Is separated from the collar 78 of the collared sleeve 76 by 12
Have eight. As mentioned above, the collared sleeve 76 is lifted with the plate 74 when lifting the lid 50. After overcoming the gap 128, the collar 78 carries the sleeve portions 120-126 together so that the container top 98 is pulled apart from the container bottom 96. In this separated posture, the wall plates 102 and 104 are opened in a double door.

FIG. 1 additionally shows a clamp 130, which serves to tie the lid 50 to the container top 98.

When the mixing process is finished and the container has to be cleaned, the clamp 130 is first released. Then, pressure is applied to the air cylinder 68, and the lifting rod 72 and the plate 74 support the lid 50, so that the lid is lifted from the container. Subsequently, the lid 50 can be swung laterally while rotating the sleeve 76 with a collar around the upper portion of the stand pipe 64. Then, the lid 50 is tilted about 90 degrees by the rotation driving device 90 as shown in FIGS. 5 and 6. This is tilted about the axis 92 of the sleeve 86 supporting the lid, while the lateral pivoting of the lid occurs about the axis labeled 132 of the standpipe 64 of the lifting device. Be done. In essence, this clamp 108, which connects the container top 98 with the container bottom, is finally released. Upon further lifting of the lifting rod 72, the collar 78 of the collared sleeve 76 grips the four-sleeve portion 120, 122, 124, 126 which secures the support arms 110, 112, 114, 116 of the container top 98. Therefore, the upper part of the container is lifted from the lower part of the container. After opening the high speed fastener 106, the semi-cylindrical wall plates 102, 104 are opened in a pattern. At the same time, the corresponding sleeve portions 120, 122, 124, 126 are rotated about the collared sleeve 76 or its axis 132. FIG. 5 and FIG. 6 show the opened posture.

Thus, the lifting mechanism first removes the lid from the top of the container, and subsequently removes the top of the container from the bottom of the container, during which time the lid is lifted much higher. That is, the lid 50
Keeps a sufficient distance from the top of the container that its lid must also be pivoted laterally after removing the top of the container.

Each lifting operation can be controlled manually or by using a terminal switch or fully automatically.

It is also possible to prepare a new servo motor for pivoting the lid to the side and opening the container with a pattern.

As shown in FIG. 1, the present invention is also applicable to a mixing container with a jacket for cooling or temperature control.

7 to 10 show another embodiment of the present invention. This is different from the embodiment described above, so it is necessary to explain it.

In the case of the embodiment shown in FIGS. 7 to 10, the prime mover 2
A trapping post 140 stands on the opposite side of the container 20 opposite the two. The lower part of the container labeled 96 of the mixing container 20 is basically formed as in the first embodiment, but the upper part of the container labeled 142 is the upper part 98 of the first embodiment. Differs from the fact that the container part 142 cannot be opened in a double fold and is formed as an integrated ring or cylindrical part. The pillar 140 includes a stationary lower shaft 114 and a sleeve 146 that is movable while sliding on the lower shaft 114 and that can be lifted and lowered. A horizontal mandrel 148 emerges from the upper end of the sleeve 146, which extends radially towards the container top 142. Lifting the sleeve 146
As can be seen by comparing FIG. 8 and FIG.
2 can be removed from the lower part 96 of the container and lifted away via a stirrer, mixer shaft, etc., not shown.

The sleeve 146 is simultaneously rotatable about the axis of the lower shaft 144. After the container upper part 142 has been lifted to the side of the mixer (FIG. 9),
It becomes possible to turn along the double arrow 150 in FIG.
The outward pivoted position shown in phantom is labeled 142 '. In addition to this, the container upper part 142 'can be swiveled 90 degrees about the horizontal mandrel 148, so that the rotation axes of the upper parts 142 to 142' of the cylindrical container are horizontal. This position is labeled 142 "in FIG. 10 and is shown by the solid line. When the container upper part 142 is in this position, it is also shown in FIGS. 7, 8 and 9 as well. Cleaning is also easy because the inside of the upper part is particularly accessible.By vertically shifting the sleeve 146 on the shaft 144, the upper part of the container can be adjusted to a desired height, so that work can be performed. The conditions can be further improved.

Besides, FIG. 10 makes it possible to recognize other advantages provided by this embodiment. A horizontal mandrel 148'152 is additionally mounted on the vertical column 140 or on the movable sleeve 146 of this vertical column. These horizontal mandrels 1
Two container upper parts 142 can be suspended from 48 'and 152. FIG. 10 shows another container component 154 by a dotted line based on the postures of both ends of the turning motion about the horizontal axis. Therefore, it is possible to use one of the upper parts of the container for the mixing step each time and at the same time wash the other part. This can further reduce the downtime between the two mixing steps.

As with the first embodiment, this embodiment also
Similarly, a suspension 50 and a lid 50 with all the details are prepared. However, it is used in the first embodiment, between the container 20 and the prime mover 22, and in the case of the first embodiment on the stand pipe 64 at the top of this container which can be lifted or opened in a double door. The suspension device provided is omitted. These parts are this second
In the case of the embodiment, a container top 142 integrated with an additional post 140 is substituted.
