Here, the washing liquid can be injected into a recovery tank (not shown) provided with the filter, and the filtered washing liquid can be recycled.

Each path formed in the main body 100 of the mixed fluid injection apparatus 10 according to an embodiment of the present invention may be formed so as to pass through the main body 100. In the processing hole formed for processing, Can be inserted to prevent outflow of the subject, hardener, washing liquid or air to the outside.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that various changes and modifications will be apparent to those skilled in the art. And various modifications and variations are possible within the scope of the appended claims.
