  However, in the above prior art, since the outlets of the two flow paths are formed at positions close to the gap between the Mixin Groter and the mixer pipe, away from the lower opening of the penetrating part. The mainstream is to flow downward from the gap and merge, and the two types of chemicals that merged in the gap between the upper surface of the Mixing Groter and the lower surface of the head part will stop and completely cure, so the mixing Groter immediately rotates. There were problems that had to be solved, such as being obstructed and increasing the frequency of maintenance.

  In view of the problem that the two types of chemicals that join together in the gap between the upper surface of the Mixin Groter and the lower surface of the head portion are stopped and completely cured based on the above-described conventional technology, A means for supplying various kinds of chemical solutions is arranged in an opposing state, a rotary mixer is arranged at the lower part of the head part, a drive motor for the rotary mixer is arranged at the upper part, and the penetrating part is formed vertically through the head part. The upper end of the inserted drive shaft is connected to the drive motor, and the mixer rotator in the rotary mixer is attached to the lower end, and the receiving port for the chemical solution supply means is formed in the head portion, and is continuously formed in one receiving port. The flow path formed in communication with the penetrating part is used as a lower opening of the penetrating part, and the flow path continuously formed in the other receiving port is formed in an inverted L shape. The outlet is formed on the lower surface of the head portion, and a seal member is provided between a portion of the inner peripheral surface of the penetrating portion above the communication portion of the one flow path and the outer peripheral surface of the drive shaft. By providing the drive shaft so as to be rotatable, one chemical solution is supplied from one outlet located at the center of the lower surface of the head portion through a gap between the upper surface of the Mixin Groter and the lower surface of the head portion. The above-mentioned problem is solved by making the fluid flow to the gap side between the pipes so as not to be constantly stagnated.

In short, in the present invention, means for supplying two kinds of chemical solutions are arranged opposite to each other on both sides of the head part, a rotary mixer is arranged at the lower part of the head part, and a drive motor for the rotary mixer is arranged at the upper part. The upper end of the drive shaft that is inserted into the through-portion formed in the head portion is connected to the drive motor, and the mixer rotator in the rotary mixer is attached to the lower end, and the chemical solution supply means is received at the head portion. An inlet is formed as an opening, a flow path formed continuously at one receiving port is formed so as to communicate with the penetrating part, and an outlet thereof is used as a lower opening of the penetrating part, and a flow formed continuously at the other receiving port. A path is bent in an inverted L shape, and an outlet thereof is formed on the lower surface of the head portion. A portion above the communicating portion of the one flow path on the inner peripheral surface of the penetrating portion and the drive unit are formed. Since the seal member is provided between the outer peripheral surface of the shaft and the drive shaft is rotatable, one outlet is formed in the center of the lower surface of the head portion, so that one chemical solution is mixed from the one outlet. Since it can always be supplied to the gap between the upper surface of the rotor and the lower surface of the head part, the stagnation of the chemical solution in the gap can be completely prevented, and thus the occurrence of problems associated with complete curing in the rotary mixer. Can be prevented and the maintenance period can be extended.
In addition, since only one of the chemical liquids is filled below the seal member in the penetrating part, the other chemical liquid can be prevented from flowing in, so that mixing of two liquids in the penetrating part can be prevented. Its practical effect is great, such as a maintenance-free configuration on the side.
