[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 4The utility model provides a stirring and mixing device for a metal surface treatment agent, which comprises a support frame 1, on which a stirring barrel 2 with an open upper end is supported, a material outlet at the bottom of the stirring barrel 2 is connected to a circulation pipeline 3 conveyed by a conveying pump 4, a frame plate 5 is horizontally arranged on the top of the support frame 1, a motor 6 is downwardly arranged on the upper end of the frame plate 5, a stirring assembly 7 is connected to the output shaft of the motor 6, the stirring assembly 7 comprises a stirring shaft 7.1 keyed to the output shaft of the motor 6, a plurality of shaft sleeves 7.2 are mounted on the stirring shaft 7.1, and stirring blades 7.4 arranged obliquely are uniformly distributed on the left and right sides of the shaft sleeve 7.2 along the circumferential direction of its axis, the oblique stirring blades can stir the mixed liquid up and down during stirring, so that the mixing is more uniform, the left and right sides of the shaft sleeve 7.2 are vertical planes, and the stirring blades 7.4 are fixed to the vertical planes by welding. The raw materials are poured into the mixing barrel and mixed by the mixing component. The various raw materials of the metal surface treatment agent have different densities, and stratification will occur under the action of the centrifugal force of stirring. The inclined stirring blades can stir the mixed liquid up and down during stirring, so that the mixture is more evenly mixed, and the raw materials are circulated through the circulation pipeline to produce the metal surface treatment agent.
