The purpose of this utility model is achieved through the following technical solutions: for the agitator tank that etching solution is processed, comprise inner hollow, and the tank body of an end opening, the openend of described tank body is provided with seal cover, is provided with motor on the seal cover, and described motor is connected with decelerator, decelerator is arranged between seal cover and the motor, described decelerator is connected with power transmission shaft, and power transmission shaft is connected with agitating device, and agitating device is arranged on tank interior.
Further, be provided with two fixed heads that be arranged in parallel on the described seal cover, be provided with bracing frame on the fixed head, power transmission shaft is arranged between the fixed head.
Further, support frame as described above comprises four supporting legs and is provided with the gripper shoe of through hole, supporting leg is divided into two groups, each group is arranged on respectively on the corresponding fixed head, gripper shoe is arranged on the top of supporting leg, and be connected with supporting leg is vertical, the center line of through hole and the center line of power transmission shaft are on same straight line.
Further, described decelerator is arranged on the gripper shoe and an end contacts with gripper shoe, and the other end contacts with motor, and the center line of decelerator and the center line of through hole are on same straight line.
Further, be provided with charging aperture on the described seal cover, and a side of described charging aperture is connected with the sidewall of tank body.
Further, described tank body and seal cover all are to adopt plastics to make.
In sum, the beneficial effects of the utility model are: this agitator tank simple in structure, production cost is low, can effectively the etching solution in the tank body be stirred incessantly, prevents the precipitation of etching solution, makes things convenient for the carrying out of subsequent treatment work.
