Description

[Detailed Description of the Invention] The present invention relates to a powder mixer that improves mixing efficiency, workability such as attachment and detachment of containers, and safety.

Conventionally, as shown in FIG. 1, a powder mixer has a double cone type mixing tank 1 with a powder inlet 2 at the upper end.
A discharge port 3 is provided at the lower end, and the mixing tank 1 is fixed to a rotating shaft 5 connected to a drive source 4, or a V
Generally used is a mixing tank 1 of a mold, with input ports 2, 2 provided at the upper end thereof and an outlet 3 provided at the lower end thereof, and the mixing tank 1 fixed to a rotating shaft 5 connected to a drive source 4'. There is.

However, in all of the mixers having the above structure, the rotating mixing tank 1 is fixed to the rotating shaft 5 and cannot be removed.

Therefore, when the mixing ratio of the mixture changes, or when mixing contents that are sensitive to foreign matter or contamination, drain all the mixed material from the mixing tank each time, thoroughly wash and dry the inside, and then In order to add new contents, the mixer must be stopped during that time, resulting in extremely poor work efficiency.

Also, since the mixing tank 1 is fixed, when transporting the mixture to the next process, the mixture must be discharged from the mixing tank 1 and received in another container before being transported to the next process. First, there is a problem in that the mixed powder and granules spill or scatter during this discharge work, contaminating the work environment.

Furthermore, since the mixing tank 1 is symmetrically supported by a rotating shaft 5 installed horizontally, the powder and granules to be mixed move in a specific trajectory within the mixing tank 1, resulting in various problems such as poor mixing efficiency. There were drawbacks.

In view of these points, the present invention improves mixing efficiency, makes it possible to replace the mixed powder and granules in their entire container, and mixes a variety of types with one mixer, minimizes the downtime of the mixer, and The present invention has developed a powder mixer in which the container can be easily and reliably attached to and removed from the mixer, improving workability and greatly overcoming the drawbacks of conventional devices.

That is, the present invention provides a powder mixer equipped with a container holding mechanism for removably holding a container containing powder, which includes a polygonal cylindrical rotating casing that houses a container with a flat outer surface, and a rotary casing that houses a container with a flat outer surface. A container holding mechanism is constituted by a container loading/unloading □ attached to the sink, a container holding fitting provided in the casing so as to be freely removable and retractable, and a rotating shaft extending obliquely to the side surface of the casing,
The powder mixer also includes a drive source in which the rotating shaft is connected to a drive source.

The present invention will be described in detail below with reference to embodiments shown in the drawings.

Figures 3 and 4 show an embodiment of the present invention.
This powder and granular material mixer includes a rectangular parallelepiped container 6 for storing powder and granular material, a rotating casing γ having a square cylindrical cage shape that houses this container 6, and a rotary casing 7 arranged so as to match the diagonal line of the rotating casing 7. It consists of a rotating shaft 5 that extends and supports the casing 1, and a hydraulic drive source 4 that is connected to the rotating shaft 5.

The container 6 into which the granular material is placed is formed of a metal rectangular parallelepiped and has an input port 2 on the top surface and a discharge port 3 on the bottom surface, and a plurality of such containers 6 are prepared.

Furthermore, the rotary casing 1, which is shaped like a rectangular cylindrical cage and which houses the container 6, has a door 8 for loading and unloading the container hinged to the front thereof so as to be openable and closable, and is secured by a locking device 9VC. There is.

Further, on the upper part of the rotating casing 7, there are clamping fittings 10 for vertically supporting and fixing the stored container 6.
and clamping fittings 10 for horizontally supporting and fixing the container 6 are attached to both the left and right sides.

The clamping fittings 10 are operated by hydraulic cylinders and are designed to prevent the container 6 from moving during rotation.

Further, a rotating shaft 5 connected to the hydraulic drive source 4 is connected to the central part of the side surface of the rotating casing 1 so that the center of the rotating shaft is on the diagonal line a (
It is cantilevered from an oblique direction so as to be located at a position (indicated by a dashed line in the figure).

The hydraulic drive source 4 is composed of a hydraulic motor and a hydraulic unit that controls the hydraulic motor, and the hydraulic unit further includes a pressurizing pump, a solenoid valve that operates the pump, a piping device that connects these, and the like. .

Further, these hydraulic drive sources 4 are housed in a casing 12 to which a base 11VC is attached.

To explain the operation of the powder mixer having the above configuration, first, the powder and granules to be mixed are put into the container 6 at a desired mixing ratio.

Similarly, powder may be placed in another container 6' in advance.

Next, this container 6 is lifted by a carrier such as a forklift and stored in the rotating casing γ, and then
is closed and locked, and then the clamping fittings 10 are extended to hold the stored container 6 from above and horizontally to fix it so that it does not move during rotation.

Next, the hydraulic drive source 4 is driven to rotate the container 6 together with the rotary casing 7 to mix the powder and granular materials.

In this mixer, the rotating casing 7 rotates around the diagonal line a, which is the center of its rotational axis, so that the powder and granules introduced are dispersed in a rectangular parallelepiped container 6 while forming an irregular trajectory. Mix thoroughly.

In particular, in a rectangular parallelepiped container with corner portions, such as the container 6, mixing is performed with better mixing efficiency than in a cylindrical container.

After mixing for a desired time in step 5, the hydraulic drive source 4 is stopped to restore the original state.

Next, the clamping fittings 10 of the rotary casing 1 are contracted and loosened, and s8 is opened to take out the mixed powder and granular material together with the container 6 using the conveyor and convey it to the next process.

Separately from this, another container 6 into which the powder and granules to be mixed are previously placed is lifted up by a transporter, stored in the rotating casing 7, and mixed in the same manner as described above. Work efficiency can be improved by minimizing downtime of the machine.

In the above embodiment, a rectangular parallelepiped was used as the container 6, but the present invention is not limited to this, and may be a cylindrical or elliptical container, but a rectangular parallelepiped with square corners to improve mixing efficiency may be used. The most desirable one is

Further, the rotating casing 1 is not limited to a rectangular cylindrical shape, but may be any polygonal cylindrical shape having a pentagonal shape or more, or a polygonal cylindrical shape in which a part of the polygonal cylindrical shape is curved to provide a radius.

Further, the rotating casing 1 is not limited to one formed in a liquid state, and may be formed in a box shape like the container 6.

Furthermore, the n8 provided on the rotating casing 7 is not limited to being provided on the front surface, but may be provided on both the front and rear surfaces so that the container 6 can be loaded and unloaded from opposite directions. The metal fitting 10 may be of any type, such as a jack type or a screw type.

Further, the rotating shaft 5 supporting the rotating casing 7 is not limited to one whose Ki is aligned with the diagonal a of the casing 7, but may be in any direction as long as it is inclined with respect to the side surface of the rotating shaft. 5 is not limited to being installed horizontally, but may be installed inclined upward or downward.

Furthermore, this rotating shaft 5 is connected to the rotating casing 7 as in the above embodiment.
The support is not limited to one side, but may be supported from both sides.

Further, the drive source 4 is not limited to a hydraulic type, but may be an electric drive type, and in this case, the electric drive type is composed of an electric motor and a brake.

As explained above, according to the powder mixer according to the present invention,
The entire container containing the mixed powder and granules can be easily replaced with another container containing the powder and granules to be mixed in advance, minimizing downtime and allowing the entire container to be mixed with a single mixer. Can be mixed efficiently.

The container can also be securely fixed to the casing of the Nu mixer using the clamping fittings.

As a result, when mixing materials with different mixing ratios or materials that are sensitive to foreign matter or contamination, workability is significantly improved and the mixing operation can be performed safely.

In addition, such a container can be easily removed from the mixer, making it easy to remove, and the mixed powder and granules can be sent to the next process while still being stored, which eliminates the need for discharging work as with conventional equipment. It is possible to prevent contamination of the working environment.

Further, according to the present invention, since the rotary casing is rotated while being inclined, the powder and granules contained in the container are sufficiently mixed, resulting in remarkable effects such as excellent mixing efficiency.
