Description

[Detailed Description of the Invention] The present invention relates to an improvement of an apparatus for mixing and stirring powder and granular materials and chemical solutions in batches, and for pulverizing lumps.

When a mixer/pulverizer is used to knead and stir granules and chemical solutions, or to crush lumps, the progress of these processes has conventionally been detected by temporarily stopping the machine, taking out the processed material, and then This has been done either by detecting it by applying it to a predetermined detector, or by guiding a portion of the processed material to a detector while the machine is running continuously.

However, with both methods, it takes time to obtain the detection results.The former method requires the machine to be stopped for a long time, resulting in poor productivity, while the latter method requires processing until the detection results are available. As the processing progresses, there is a problem that the processing results are largely different from the desired processing state.

This invention was made to solve the above problems.
It is an object of the present invention to provide a kneading/pulverizing machine capable of easily and accurately detecting the degree of progress of kneading powder or granular material or crushing agglomerates even while the machine is continuously operated.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a cylindrical crosstalk tank with a flat bottom plate, which is installed on a foundation via four leg members 2.2.

A rotating shaft 3 oriented vertically is rotatably mounted at the center of the mixing tank 1, and a support member 4 extending left and right is fixed to the upper end of the rotating shaft 3.

Two support pins 5, 5 oriented in the front-rear direction are fixed to the front and rear surfaces of the support member 4 symmetrically about the rotation axis 3, and L-shaped links 6 are attached to the support pins 5, 5. .6 is rotatably fitted in the bent position.

Rotating wheels 8, 8 are vertically rotatably supported at the lower end of the link 6.6 via support shafts 7, 7, and one end is supported at the upper end of the link 6.6 via brackets 9, 9. Support member 4
The other end of the tension coil spring 10.10 attached to the coil spring 10.10 is connected to the rotating ring 8,8.
The links 6, 6 are rotated about the support pins 5, 5 by the pulling of the kneading tank 1, thereby pressing the objects to be processed in the kneading tank 1 with a constant force.

Further, a funnel 11 for adding a predetermined chemical solution to the mixing tank 1 is fixed to the center of the upper surface of the support member 4.
A displacement meter 12.12 for detecting the level of the lower end of the link 6.6 is attached to the outer surface of the link 6.1 via brackets 13, 13. .6 is abutted on the lower end.

Note that 14 and 15 are souffle bars that scratch the top surface of the bottom plate of the mixing tank 1, 16 are souffle bars that scratch the inner surface of the body of the kneading tank 1, and 17 is a drive device for rotating the rotating shaft 3 in a predetermined direction.

With this structure, the powder and granules and the chemical solution or the lumps are put into the kneading tank 1, and the rotating shaft 3 is rotated clockwise in FIG. 15. Mixing or crushing powder, granules, etc. or lumps with the rotating wheels 8, 8 while scraping in step 16 is similar to the kneading and crushing machine in the United States, but in this case, when kneading powder or granules, As the crosstalk progresses, the powder becomes viscous and adheres to the bottom of the crosstalk tank 1 in a layered manner.
The resistance pressure of the granular material against the rotating wheels 8, 8 increases, and the level of the rotating wheels 8, 8 pressing the granular material gradually rises,
This is detected via link 6.6 by displacement meter 12.12.

Therefore, by determining in advance the correlation between the level of the rotating wheel 8 and the viscosity of the powder, the degree of kneading of the powder can be perceived from the data of the displacement meter 12. When crushing something, as the lumps are crushed, they become finer and are passed through the rotating wheel 8.8.
gradually decreases, which is also detected by displacement meter 12.12 via link 6.6.

Therefore, similar to the above-mentioned mixed line of powder and granular materials, the rotating wheel 8,
By determining the correlation between the level of 8 and the degree of crushing of the lumps in advance, the degree of progress of crushing of the lumps can be perceived from the data of the displacement meter 12.12.

In the embodiment described above, the level of the rotary wheel 8 is detected, but it is also possible to detect the level of an appropriate pressing means that is elastically supported and is configured to constantly press two surfaces of the workpiece. It may also be detected.

As is clear from the above explanation, the present invention has a displacement meter fixedly disposed inside the kneading tank to detect the level of the rotating wheel or the level of the pressing means that can constantly press the top surface of the workpiece.・Since it is a crusher, when kneading powder or pulverizing lumps, it can detect the upper surface level of the powder, which moves up and down depending on the progress of the processing, even while the machine is running continuously. This provides excellent practical effects such as being able to accurately and easily perceive the degree of progress of these processes.
