Abstract

PURPOSE:To efficiently produce granular material improved in strength and in uniformity of grains, by oscillating a vessel by a oscillation generator to put a material packed in the vessel in a oscillating fluidization, and agitating the material by a chopper with a high speed. CONSTITUTION:When an eccentric weight 11 (an oscillation generator) is rotated, an oscillation is given to a vertical cylindrical vessel 21, and the material A to be treated packed in the vessel 21 is put in a good uniform oscillating fluidization state. When the chopper 51 is rotated with a high speed in the above-mentioned state, the material to be treated is disintegrated on one hand, and on the other hand granulated at the same time. The material A to be treated originally contains water to some extent and comparatively has a coagulating characteristics. Thus, by a simple optional operation, a granular material excellent in strength and in uniformly of grains is efficiently obtained.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a vibratory granulator.

Various types of granulators are used in many manufacturing and processing plants. Needless to say, these granulating machines must be capable of easily performing any granulation operation, and can efficiently perform granulation as desired in terms of strength, granulation degree, etc. is requested.

The present invention relates to a vibratory granulator that meets such demands.

<Conventional techniques and their problems> Conventional techniques include methods that dry and solidify a liquid material sprayed into a gas, methods that use a rotating drum or conveyor with a perforated plate, and methods that rely exclusively on mechanical suppression.

Various granulators are in practical use.

However, in addition to problems with the above-mentioned granulator, such as the overall size of the device being too large and the operating conditions being cumbersome, the granulate has insufficient strength and granularity, and in many cases Although it is desired to crush the material to be processed and granulate it at the same time, it is difficult to carry out such an operation due to the structure of the material, and in many cases, granulation is not possible under controlled conditions of temperature and pressure. Despite the desire to perform such an operation, there are various problems, such as the fact that it is difficult to perform such an operation due to its configuration.

<Problems to be Solved by the Invention> Means for Solving the Problems The present invention solves the conventional problems as described above, and produces granulated products excellent in terms of strength, granularity, etc. by simple arbitrary operations. The present invention provides a vibratory granulator that can efficiently obtain the following.

Therefore, in the present invention, the container equipped with the vibration generating source is supported by an elastic body such as a spring so as to be given a certain kind of free movement.
A chopper is attached to the container, and the object to be processed filled in the container is vibrated and fluidized by applying vibration to the container with a vibration source, and the object to be processed is stirred at high speed by the chopper. A first invention relating to a vibratory granulator configured to granulate particles, and in the first invention, the container is further equipped with a sprayer, and the sprayer sprays a bonding medium onto the vibratory fluidized workpiece. The second invention is characterized in that the object to be processed is agitated at high speed by a chopper while being supplied.

The important point of the present invention is that the material to be treated is vibrated and fluidized in a container and is agitated at high speed with a chopper, and at the same time, a binding medium is supplied by spray. It is composed of:

Hereinafter, the configuration of the present invention will be explained in more detail based on the drawings.

<Embodiment> FIG. 1 is an overall side view showing an embodiment of the present invention. Vertical cylindrical container 2 equipped with an eccentric weight 11 as a vibration source
1 is supported on a base 31 by springs 41 and 42. A chopper 51 is inserted into the vertically placed cylindrical container 21 whose top surface is open.

The vertically placed cylindrical container 21 is supported by springs 41 and 42 to give it some kind of free movement, and when a motor (not shown) is driven to rotate the eccentric weight 11,
Vibration is applied to the vertically placed cylindrical container 21, and the vertically placed cylindrical container 2
This is a configuration in which the processed material A filled in the container 1 is vibrated and fluidized, and the chopper 51 agitates the processed material A at high speed.

Fig. 2 is an overall side view (partially omitted) showing another embodiment of the present invention, and Fig. 3 is a partially enlarged internal view of the embodiment. A horizontal cylindrical container 22 equipped with an eccentric weight 12 as a vibration generating source is supported by springs 43 and 44 on a base 32. A jacket 61 for circulating a heating or cooling medium is provided around the closed horizontal cylindrical container 22, and the inside thereof is communicated with a vacuum pump 62, and the inside is connected to a pipe from the outside. A sprayer 71 and a chopper 52 inserted from the outside are attached.

The horizontal cylindrical container 22 is supported by springs 43 and 44 to give it some kind of free movement, and when a motor (not shown) is driven to rotate the eccentric weight 12,
Vibration is applied to the horizontally placed cylindrical container 22, and the horizontally placed cylindrical container 2
The object to be treated B filled into the chamber 2 is fluidized by vibration. And on this occasion.

For example, water vapor as a heating medium is circulated into the jacket 22, and while the pressure inside the horizontal cylindrical container 22 is reduced by the vacuum pump 62, the spray 71 as a bonding medium is applied to the vibratory fluidized workpiece B. For example, the processing object B is agitated at high speed by a chopper 52 while an organic binder solution is being sprayed.

Although the illustrated embodiments are both preferred examples of the present invention, the present invention has a number of features such as the shape and structure of the container itself, the number of vibration sources and springs, the form of the chopper and spray, etc.
For example, the shape of the container may be U-shaped, and the container may have a supply port and a discharge port for the material to be processed, and a perforated plate may be provided to separate the discharge port. You can also leave it there. In addition, already known choppers and sprays can be used, and water may be used as the binding medium, depending on the type and properties of the material to be treated.
Furthermore, it is appropriately selected depending on the characteristics such as particle size desired for the granulated product.

Next, the operation of the present invention will be explained based on the illustrated embodiment. When the eccentric weights 11 and 12 are rotated by driving a motor (not shown), the vertical cylindrical container 21 or the horizontal cylindrical container 22 is rotated.
Vibration is applied to the objects A and B filled in the container, and the objects A and B are brought into a good and uniform vibration-flowing state. In this state, in the case of the embodiment shown in FIG. 1, when the chopper 51 is rotated at high speed, the material to be processed A is crushed on one side and granulated on the other at the same time. The object A to be treated originally contains a certain amount of moisture and is relatively highly cohesive, or it is mixed with a binding medium in advance, or it is treated in the same state as above. In the case of the embodiment shown in FIG. 2, the binding medium is sprayed from the spray 71 onto the workpiece B under predetermined temperature and pressure conditions (it goes without saying that the spraying does not necessarily have to be carried out continuously), When the chopper 52 is rotated at high speed, the object to be processed B is crushed on one side and granulated on the other side at the same time. In both examples, since the material to be treated is subjected to high-speed agitation by a chopper in a vibratory fluid state, granules with excellent strength, particle size distribution, etc. can be obtained.

<Effects of the Invention> As explained above, the present invention has the effect of being able to efficiently obtain a granulated material excellent in terms of strength, particle size distribution, etc. by a simple arbitrary operation.
