Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a two-component lining material mixer that can be used, for example, to prepare a two-component lining material used for lining pipes.

Conventional technology and its problems Conventionally, mixers used to prepare two-component lining materials for pipes, etc. mix the main component and curing agent of the lining material by rotating a rotating body driven by an air motor. There are two known methods, one in which the lining material is mixed with a static mixer and the other in which it is mixed using a static mixer, but these known methods are not very effective in mixing the main lining material and hardening agent, considering the complexity of the structure. Nakatsuta.

Therefore, the present invention eliminates the drawbacks of the above technology,
The object of the present invention is to provide a two-component lining material mixer that has a simple structure and can effectively mix a main lining material and a curing agent.

Means for Solving the Problems In order to achieve the above object, the two-component lining material mixer of the present invention has a first spiral flow path through which compressed air is swirled in a direction around an axis; A second flow path for flowing the main agent of the lining material and a third flow path for flowing the curing agent, which are separated from each other, are arranged such that the first flow path is on the inside and the second and third flow paths are on the inside of the first flow path. It is characterized in that it is disposed outside the channel, and a mixing chamber is connected to the outlet side of the first, second and third flow channels, in which the main ingredient of the lining material and the curing agent are mixed by the compressed air.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings.

A member 4 having a spiral-shaped first flow path 3 is provided on the end side (left end side in FIG. 1) of the inner space 2 of the annular body 1. A second flow path 5 and a third flow path 6 are provided on the outside and separated from each other. The flow passages 5 and 6 can have their end portions shaped like holes 5a and 6a, and the other portion shaped like an annular passage along the axis of the inner space 2. Said annular body 1
A compressed air source, for example, an air compressor (not shown) is connected to the starting end of the inner space 2, and a pump (not shown) is connected to the starting end of the second flow path 5 for pumping the main ingredient of the lining material. ) is connected to the starting end side of the third flow path 6, and a pump (not shown) for pumping the curing agent for the lining material is connected to the starting end side of the third flow path 6.

The compressed air from the first flow path 3, the compressed air from the first flow path 3, and the second flow path 5 A mixing chamber 7 is provided to mix the main lining material from the lining material and the curing agent from the third flow path 6, and the inlet of the mixing chamber 7 is connected to the end side of the flow paths 3, 5, and 6, that is, the exit side. Connect to. The mixing chamber 7 is connected to the flow paths 3, 5 and 6.
On the side opposite to the side to which the lining material is connected, there is a spout 8 for spouting out a mixture of compressed air, a lining material base material, and a curing agent. If necessary, a deflector plate 9 extending in a direction perpendicular to the axis of the jet nozzle 8 is disposed near the front surface of the jet nozzle 8 . The mixing chamber 7 includes a conical torpedo-shaped body 10 with a conical tip end, a flow path 3,
It is located inside the chamber 7, facing the end sides of the tubes 5 and 6. Further, the mixing chamber 7 has a cylindrical tip portion 1 forming a spout 8.
1. Located in the front end zone of the inclined cylindrical part 12 following the part 11 and the cylindrical part 13 that forms the main body of the chamber 7,
It has a core 14 arranged concentrically with the sections 11, 12, 13, and a flow path 15 is formed between the core 14 and the zones of the sections 11, 12, 13. The torpedo-shaped body 10 and the core 14 may be of a separately combined type or a single unit, and may be supported by a support body 16 fixed to the inner surface of the cylindrical portion 13.

In the illustrated embodiment of the mixer of the present invention, compressed air is fed into the mixing chamber 7 through the first channel 3, and the main ingredient of the lining material is introduced into the mixing chamber 7 from the second channel 5. When the curing agent is introduced from the flow path 6, the compressed air follows the spiral of the first flow path 3 and flows into the mixing chamber 7 as a swirling flow that is swirled in the direction around the axis. The lining material main ingredient from 5 and the curing agent from the third flow path 6 are stirred and mixed in the mixing chamber 7. In this case, since the first channel 3 is arranged inside and the second channel 5 and third channel 6 are arranged outside the first channel 3, the ends of the channels 5 and 6 That is, the compressed air that has flowed into the mixing chamber 7 as a swirling flow effectively encounters the main agent and curing agent that flow into the mixing chamber 7 from the outlet side, and the compressed air in the mixing chamber 7 causes The above-mentioned main ingredient and curing agent are effectively mixed.

When the mixer of the present invention is equipped with a baffle plate 9, the mixture of compressed air in the mixing chamber 7, the main lining material, and the curing agent is ejected to the outside from the spout 8 through the flow path 15, and is sprayed onto the front surface of the baffle plate 9. It is sprayed and scattered in all directions.

Therefore, by placing the mixer with the deflecting plate 9 in advance inside the object to be lined, such as a pipe, and pre-injecting a mixture of compressed air, lining material base material, and hardening agent to the deflecting plate 9. , a two-component mixed lining material can be applied to the object to be lined.

Effects of the invention As described above, according to the invention, compressed air is flowed into the mixing chamber as a swirling flow through the first flow path, and the
Since the compressed air can effectively meet the lining material base material and curing agent that have flowed into the mixing chamber from the flow path and the third flow path, a simple method as illustrated in FIG. With this structure, two-component mixed lining materials can be effectively mixed using the flow of compressed air.
