Abstract

PURPOSE:To prevent secondary granulation by supporting a vessel contg. powder and granules on a base plate by means of a number of pieces of coil springs, vibrating the weights in the lower part of the vessel with a vibration generator mounted in the eccentric position of a revolving shaft, and mixing and grinding the powder and granules while ejecting compressed gases from the nozzles projected into the vessel. CONSTITUTION:A vessel 3 contg. powder and granules is supported on a cylindrical base plate 1 by means of a number of coil springs 2, and a motor 7 is mounted perpendicularly to the bottom surface of the bottom plate of the vessel 3 by means of a mounting ring 5 and mounting beams 6. Weights 9 are fitted to the eccentric position of a revolving shaft 8 projected in both top and bottom directions of said motor. Nozzles 10 of a cylindrical shape which eject compressed gases are provided in the lower part on the circumferential wall of the vessel 3. Thereupon, the motor 7 is driven to swivel the weights 9, thereby vibrating the vessel 3 and mixing and grinding the powder and granules in the vessel 3. If the compressed gases are blown to the powder and granules from the nozzles 10 at this same instant, secondary granulation is prevented.

Description

Detailed Description of the Invention The present invention generates vibrations by attaching a weight to an eccentric position of a rotating shaft of an electric motor, etc., and mixes powder or granular material in a container. This invention relates to a particle vibrator.

The medicine contained in the container is vibrated.

Foods, various types of Haraichi 4, etc. powders can be mixed together, or crushed as described in Matakejitsuko S. Goo No. 4110,
Alternatively, a vibrating device equipped with a sieve for separation is well known.

By the way, when such a vibrating device is used to image a powder or granule, if the powder or granule has some lag or viscosity, it may move inside the container.11+1. During this time, a new granulation phenomenon (this is referred to as secondary granulation) may occur, which may impede the effects of mixing, pulverization, and separation.

The purpose of vK/ of the present invention is to prevent the above-mentioned secondary granulation.

Furthermore, when the powder and granules are vibrated, frictional heat is generated, and over a long period of time, the heat accumulates and reaches a high temperature, which may impede the mixing of explosives.

Therefore, the first object of the present invention is to enable the powder and granular material to be effectively cooled during its y-motion.

The present invention will be explained in detail below. In FIG. 1, reference numeral 1 denotes a cylindrical base, 2 several coil springs provided at intervals on the upper surface of the base, 3 containers supported via the coil springs, and 4 lids.

A vibration generator shown below is fixedly installed at the bottom of the container 3.

That is, a motor 7 is directly fixed to the lower surface of the bottom plate of the container 3 with a mounting ring 5 and a mounting rod 6, and a weight 9 is mounted at an eccentric position of a rotating shaft 8.8 of the motor 7 that projects upward and downward. , 9 are detachably attached.

Reference numeral 10 denotes a cylindrical nozzle that protrudes from the circumferential wall of M3.The tip of the nozzle is closed and a number of nozzle holes are opened around the nozzle. The liquid is supplied and ejected from the nozzle hole. Note 1]
is a cone formed at the center of the container 3.

In the device configured in this way, if the powder granules are stored in the container 3 and the weight 9.9 is rotated by the drive of the electric motor 7,
Vibrations and swings are applied to the electric tiles 7 due to the imbalance, and the container 3 vibrates. For this reason, the powder and granules move in a spiral manner within the container and are mixed, stirred, or pulverized. At that time, if the squeezing medium 9 is ejected from the surface of the nozzle 10 and sprayed onto the moving powder or granules, the clumps of powder or granules can be cut and moved, and the secondary granulation is effective because it can destroy the snowball-like growth. There are six ways to prevent this.

Here, the shape of the nozzle 10 is not limited to the cylindrical shape shown in the embodiment, but can also be triangular or elliptical to change the movement of the powder and granules. Of course, there are thousands of options for the number or one column. Furthermore, the nozzles can be formed in the membrane so that matching landings can be made, and the nozzles can be fixed in an inclined manner as shown in Figure 3, or each nozzle is connected in a Y shape as shown in Figure 3. It can also be carried out.

In addition, it is possible to supply not only 7L of empty sword from the nozzle, but also reactive gas with powder and granules, non-oxidizing gas, etc., depending on the purpose, as well as low
It can also be safely used for mixing explosives, etc. by blowing out powder gas and cooling the powder.

Furthermore, it is also possible to carry out processes such as drying or reaction promotion simultaneously by blowing out high-temperature gas.

As described above with respect to the embodiments, the powder vibrator M according to the present invention has the effect of effectively preventing secondary granulation of powder and granules.
