Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mixing vessel,
More specifically, the present invention relates to a mixing container suitable for uniformly mixing a plurality of types of liquids, or a liquid and a powder or the like (hereinafter, referred to as “liquid or the like”).

[0002]

2. Description of the Related Art Conventionally, a mixing container provided with a stirrer in which a plurality of rotary stirring blades are arranged on the outer periphery of a stirring rod in a container body for uniformly mixing a liquid or the like has been known. I have. However, in this mixing container, since the stirring blades rotate only in one direction, it is difficult to mix liquids with each other, for example, when mixing a plurality of types of liquids having a large difference in viscosity or specific gravity, or a case where a liquid and a granular material are to be mixed. In some cases, the flow of the liquid or the like becomes unidirectional and the stirring cannot be performed sufficiently.

[0003] Therefore, a baffle plate is provided fixedly on the inner surface of the container so that the stirring blades do not hit it, and a turbulent flow is generated (for example, the column of the embodiment of Japanese Patent Application Laid-Open No. 10-337461) to reduce the stirring effect. It has been proposed to list.

However, when a liquid or the like is mixed by using such a container, not only the stirring blades hinder the supply of the liquid or the like, but also, for example, the liquid to be mixed contains air or the like. If there is a liquid component that reacts and solidifies with water, the liquid or the like hits the stirring blade or stirring rod, entrains air, and the liquid component reacts with water in the air and solidifies,
Attached as solids around the stirring blade and around the stirring rod,
In some cases, the stirring ability was reduced, or the attached solid material was peeled off and dispersed in the liquid.

Further, the effect of the stirring blade is hardly obtained at the bottom of the container, and there are problems that a liquid having a large specific gravity is separated and solids dispersed in the liquid precipitate.

[0006]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, and makes it possible to uniformly mix a plurality of types of liquids having a large difference in viscosity or specific gravity, or even to mix a liquid and a granular material. Even if there is a liquid component that reacts with moisture in the air and solidifies in the liquid to be mixed, solids due to the liquid component are not generated, and the bottom of the container is also formed. It is an object of the present invention to provide a mixing container capable of mixing uniformly.

[0007]

According to the present invention, there is provided a mixing container comprising: a container body; a vibrator for imparting mechanical vibration to the container body; and a propagating mechanical vibration from the vibrator to the outside of the container. It comprises a vibration absorber for suppressing, and a baffle plate is provided on the inner wall of the container body so as not to rotate.

[0008] The vibrator used in the present invention is not particularly limited as long as it can vibrate the container body, and ordinary vibrators, vibrators, industrial vibration motors and the like are used.

The frequency of vibration when the container body is vibrated by the vibrator is not particularly limited because it varies depending on the viscosity and the natural frequency of the liquid to be mixed.
For example, in the case of a Newtonian fluid such as water, if the frequency is too low, the liquid will not circulate sufficiently, and the stirring effect will be insufficient, and if it is too high, it will only wave and the circulation of the liquid will be insufficient. , 30 to 60 Hz.

If the amplitude of the vibration is too small, the liquid will not circulate sufficiently and the stirring effect will be insufficient, and if it is too large, the liquid will only swell and the circulation of the liquid will be insufficient.
It is set appropriately according to the viscosity and the natural frequency of the liquid to be mixed.

Further, the direction of the vibration may be an up-down direction, a left-right direction, a front-back direction, or any direction.

The vibration absorber used in the present invention is not particularly limited as long as it can vibrate the container body, and a damper, a spring, a vibration damping plate and the like are used.

In the baffle plate used in the present invention, when the container body is vibrated by the vibrator, the liquid or the like is swung in the container body, and hits the baffle plate to cause free vortices in the liquid or the like. It is set to occur.

The material of the baffle is not particularly limited, but, for example, a thin metal, a resilient synthetic resin, rubber or the like is used. Among them, aluminum, titanium,
Copper, iron, steel (including stainless steel) and their alloys are preferred because they can be designed not only to act as baffles, but also to provide the effect of vibration due to resonance.

The thickness of the baffle is not particularly limited, but if it is too thin, the mechanical strength is inferior. If it is too thick, the effect of vibration may be reduced. It is preferably 1.6 mm, and in the case of a synthetic resin, 4 to 6 mm.

(Function) The mixing container of the present invention has a container main body, a vibrator for applying mechanical vibration to the container main body, and a vibration for suppressing propagation of mechanical vibration from the vibrator to the outside of the container. Since it is made of an absorbent body and the baffle plate is provided on the inner wall of the container body so as not to rotate, even if it is desired to mix a plurality of types of liquids having a large difference in viscosity or specific gravity, or to mix a liquid and a granular material Since it can be mixed uniformly and there are no stirring blades or stirring rods, liquids etc. can be smoothly supplied to the container,
Even if there is a liquid component that reacts with the moisture in the air in the liquid to be mixed, the contact time between the moisture in the air and the liquid component is short when supplying the liquid to the container. ,
Therefore, no solid matter due to the liquid component is generated, and the bottom of the container can be uniformly mixed.

As shown in FIG. 1, the mixing vessel 1 of the present invention
Is composed of a container main body 2, an industrial vibration motor 3 for applying mechanical vibration to the container main body 2, and a damper 4 for suppressing propagation of mechanical vibration from the industrial vibration motor 3 out of the container 1. A lid 21 is provided on the upper side of the container body 2, a baffle plate 22 is provided on the inner wall, and a liquid discharge nozzle 23 is provided on the lower side.

The baffle plate 22 is made of SU 0.6 mm thick.
It is made of S304, and is provided on the inner wall of the container body 2 so as not to rotate. On the other hand, the liquid discharge nozzle 23 is connected to a pump (not shown) or the like.

In order to mix liquids using the mixing container 1 of the present invention, first, the lid 21 of the container body 2 is opened to supply the liquid to be mixed to the container body 2. After supplying a predetermined amount of liquid, the lid 21 is closed and the industrial vibration motor 3 is operated. Then, the vibration from the industrial vibration motor 3 is transmitted to the container main body 2, and the liquid supplied to the container main body 2 is mixed while being vibrated, and hits the baffle plate 22 to generate a free vortex, whereby sufficient stirring is performed. . Next, the industrial vibration motor 3 is stopped, the liquid discharge nozzle 23 is opened, and the sufficiently stirred liquid is discharged and applied to a desired place via a pump (not shown).

In this way, the liquid to be mixed is discharged without generating solids while being sufficiently stirred.

[0023]

Since the mixing container of the present invention is constructed as described above, even if it is desired to mix a plurality of types of liquids having a large difference in viscosity or specific gravity, or a mixture of liquid and powder, the mixing is performed uniformly. Even if there is a liquid component that reacts with moisture in the air and solidifies in the liquid or the like to be further mixed, no solid matter due to the liquid component is generated, and The bottom can also be mixed uniformly.
