Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to an apparatus for instantly mixing and applying multi-component reactive materials having particularly high viscosity.

Conventionally, main resins and curing agents such as urethane resins, unsaturated polyester resins, and alkali silicates, as well as reaction accelerators that are added as necessary, have been used.
Multi-liquid reactive materials consisting of additives etc. are mixed well before being applied to the target object.
Once mixed, reaction time is limited, so the problem is how to mix efficiently within a short period of time, and various types of condensation mixing devices have been developed for this purpose. They tend to solidify uniformly at the introduction and mixing parts of each agent, and such solidification causes pressure loss, and it is troublesome to clean the solidified parts. Furthermore, in conventional instant mixers, the shape of the nozzle part is almost fixed, and is fixed, for example, only to a spray type or only to an injection type, which does not require much pressure.

The present invention was made with the intention of solving the above-mentioned conventional drawbacks, and uses a multi-way pot in the introduction section of each agent of the multi-liquid reaction type material, and the mixing section is tubular and divided into two. Furthermore, the nozzle part is designed so that it can be easily changed to a spray type or injection type nozzle depending on the degree of pumping of each agent,
By creating a device consisting of such a series of main parts,
It is possible to reduce the occurrence of solidification, improve the ease of cleaning the solidified part, and simplify the construction method, which can contribute to a significant improvement in the workability of multi-liquid reactive materials and, by extension, in the reactivity.

The present invention will be explained in detail with reference to the drawings. FIG. 1 shows a conceptual sectional view of the entire apparatus of the present invention, which mainly consists of a mixing tube 5 of a female part 1 of a liquid introduction pot and an injection nozzle 8. The liquid introduction female part 1 is
Although the male part is omitted for the purpose of explanation, the combination with the male part will be described in FIGS. 2 to 6. Now, taking as an example the three-way pot for two-component reaction type materials shown in the figure, the reaction liquid is pumped and guided to joints 2 and 3, respectively, and either stands still at the pot, or only one liquid passes through, or two The liquid is introduced into the mixing tube 5 through the connecting joint 4 and the connecting socket 9. As shown in FIG. 7, this mixing tube 5 is divided into two in the tube axis direction, so it is fixed by a presser tube 7, and a kneading plate 6 is attached, so that the two liquids come into contact with the kneading plate and flow in the direction of flow. By being bent, the mixture is mixed in the mixing tube 5 while being kneaded in a spiral shape. The mixed liquid is then led to the injection nozzle 8 through the connection socket 9,
The mixed liquid is discharged from the tip of the nozzle.
Figures 2 to 6 are cross-sectional views of the operation status of the Kotsukosu section 10. Figure 2 shows a state in which each liquid is stationary, Figure 3 shows a state in which only one liquid passes through the joint 3, and Figure 3 shows a state in which only one liquid is passing through the joint 3. Figure 4 shows a state in which two liquids pass through joints 2 and 3 at the same time and transfers to connecting joint 4. Figure 5 shows a state in which only one liquid passes through joints 2 and 3 at the same time, and Figure 5 shows a state in which only one liquid passes through joints 2 and 3 at the same time. The purpose is to clean the pipe 5, and FIG. 6 shows the same state as FIG. 2 when the operation has been completed, and the liquid is all still. In these Figures 2 to 6, only three-sided pots are explained, but four-sided pots, five-sided pots, etc. can also be made in the same manner. It is desirable that the numbers be the same. Next, FIG. 7 shows two directions of the mixing tube 5 of the present invention in the tube axis direction.
It is a developed view to show the split structure, and kneading plates 6 are attached alternately to the upper and lower half-tubes, respectively.
These are overlapped in the direction of the arrow and fixed in a normal tubular shape with a presser ring. FIG. 8 shows a spray type nozzle 11 replacing the injection type nozzle 8 in FIG.
The spray is applied to the object through the nozzle tip 14 using the air pressure of 3. In the figure, the compressed air is supplied through the air pipe 15.
The air passes through an air nozzle 13 through an air tank 12, and the height of the air nozzle section 13 can be adjusted as appropriate.

When two-component reactive materials are instantaneously mixed using the apparatus of the present invention having the above-mentioned configuration, especially in the case of high viscosity, they can be mixed uniformly in an extremely short time under advantageous conditions, and the pot life of the materials can be shortened. There are no restrictions. In addition, even if solidification occurs partially, the supply of liquid is temporarily stopped, and during that time the pot, mixing pipe, and nozzle can be easily separated for inspection and repair, making construction work very efficient. It is. In addition, the pressure resistance of both the pot and the mixing pipe is quite strong, so whether the construction is an injection method or a spray method, it can be easily changed by simply adjusting the pumping pressure of the liquid. The materials of the pots, mixing pipes, nozzles, joints, connection sockets, etc. are not particularly specified, and can be selected from steel, plastics, etc. that are effective in engineering, and the connection means can be made using ordinary methods. good.
