Description

[Detailed Description of the Invention] The present invention relates to a mixing container for stirring and mixing fluid substances.

Conventionally, a stirring mixing tank has been proposed in which a liquid substance is supplied into a mixing tank equipped with an agitator and mixed. However, a low viscosity fluid is supplied from outside the tank to a high viscosity substance in the tank to mix or react. However, due to the difference in viscosity, it is difficult to achieve uniform mixing, and short passes of the supplied materials tend to occur.

The inventor of the present invention has conducted various studies in view of the above circumstances, and has found that the above-mentioned drawbacks can be solved all at once by providing a special structure for the supply port of the supplied substance, and has completed the present invention.

The gist of the present invention is that a conduit 6 is provided in the opening 5 of the supply pipe 2 provided by penetrating the wall of the mixing container 1, through which the substance in the container flows, and that a static mixer 1 is connected to the conduit 6.
2 in a mixing container.

FIG. 1 is a partially cutaway side sectional view of the mixing container according to the present invention, shown to make the structure of the mixing container easier to understand.

In FIG. 1, 1 is a mixing container equipped with a jacket, 2
3 is a fluid substance supply pipe, 3 is a stirring blade, 4 is a fluid substance supply inlet, 5 is an opening of the supply pipe 2 provided in the tank, 6 is a conduit,
7 is a mixed substance outlet, 8.8' is a heating medium inlet/outlet, 9 is a jacket, 10 is a mixed substance in the container, 11 is a drive device,
12 indicates a static mixer, respectively.

In the mixing container of the present invention, as shown in FIG. tube 2
It is necessary to provide a conduit 6 in the opening 5 at the tip.

Further, it is preferable that the conduit 6 provided in the supply pipe opening 5 has a shape such as a trumpet-taper shape with one side widening, as shown in FIGS. 2 and 3.

However, if a liquid feeding means for forcibly feeding the substance inside the container is provided, the container can also be formed into a cylindrical shape as shown in FIG.

This conduit 6 is further provided with a static mixer 12 for better mixing.

Further, if necessary, this conduit 6 can be provided with a direction plate 13 at the outlet of the mixer to change the direction of the fluid as shown in FIG.

In some cases, it is preferable for the supply liquid to be supplied to the conduit 6 to have a faster flow rate, and in this case, the diameter of the supply pipe can be freely changed by selecting the diameter of the supply pipe as necessary.

Also, the direction of the nozzle can be selected to be countercurrent or forward to the flow direction of the substance in the vessel flowing in the conduit depending on the properties of the substance in the vessel.
In general, forward flow is preferable.

Furthermore, the mounting position of the supply pipe 2 can be roughly divided into two cases: one is attached to the body of the container, and the other is attached to the upper and lower dish parts (mirror parts).

In either case, forced liquid feeding means may be installed to guide the substance inside the vessel into the conduit.

The liquid feeding means can be freely attached either inside or outside the container.

An example of this is shown in FIG.

15 in FIG. 5 is a liquid feeding means using a pump.

The size of the conduit 6 may be determined by considering the capacity of the container, the size of the stirrer, etc., and is not particularly limited, but it is preferable that the length to diameter ratio is 5/1 or more.

Further, as shown in FIG. 5, the opening of the conduit is preferably oriented along the flow direction of the agitated mixed substance in the tank so that good agitation and mixing can be performed.

The stirrer used in the mixing container of the present invention is as follows:
Commonly used ones, such as spiral bands, paddles, anchors, variations thereof, or combinations thereof, having vanes are used.

The mixing container of the present invention can be used in either a batch type or a flow type.

The mixing container of the present invention having the above-described structure can uniformly mix the substance in the container and the material to be supplied, and can be used as a stirring mixing tank for mixing various fluid substances or for polymerization reactions.

The container can also be adapted to both horizontal and vertical configurations.
