[0029] Example 1: A feeding device for a color sand masterbatch mixer, see Figure 1-Figure 4 As shown, it includes a support frame 1, an outer barrel wall 4, a feed inner barrel 5, a discharge hopper 7, a discharge pipe 8 and a feeding assembly. The outer barrel wall 4 is installed on the support frame 1 by bolt connection, and the feed inner barrel 5 is installed in the outer barrel wall 4 by welding. A cavity is formed between the outer barrel wall 4 and the feed inner barrel 5.

[0031] When it is necessary to feed the internal mixer, first pour the masterbatch raw material into the feed port 6 through the feed port 6, then open the ball valve 1202 by turning, and start the water pump 12 to transport the color oil auxiliary material in the water tank 10 through the water pipe 1201 to the feed inner barrel 5 to mix with the masterbatch raw material.
